Dạng phổ biến nhất là Thiếu cả tim tỳ vị hư nhược được nói đến trong 93,2% số bài, tiếp theo là Chứng hư hỏa do âm hư (63,1%), Gan khí ngưng trệ chuyển hóa thành hỏa khí (42,7%), Nội nhiệt đờm nhiệt (34,0%), Suy tim - thận (30,1%) và thiếu hụt Qi của tim và túi mật (29,1%) Mặc dù chỉ có các mẫu chẩn đoán TCM được liệt kê trong sách giáo khoa tiêu chuẩn về TCM, đánh giá của chúng tôi cho rằng không có tim - thận, không được liệt kê trong sách tiêu chuẩn , được xếp hạng giữa các mẫu chẩn đoán TCM phổ biến thứ hai đến thứ sáu theo các tiêu chí lựa chọn khác nhau Chúng tôi đã tìm thấy 23 thuật ngữ khác nhau cho các triệu chứng liên quan đến giấc ngủ và 89 các triệu chứng không liên quan đến giấc ngủ khác nhau liên quan đến wi Các mô hình hội chứng TCM đối với chứng mất ngủ Các triệu chứng liên quan đến giấc ngủ phổ biến nhất trong các tài liệu về bệnh TCM là giấc ngủ bị rối loạn giấc mơ, dễ thức giấc và ngủ không yên giấc Các triệu chứng không liên quan đến giấc ngủ phổ biến nhất là chóng mặt, hồi hộp và trí nhớ kém Ngoài ra còn có Các đặc điểm về lưỡi và mạch được đề cập trong tài liệu về bệnh TCM Chúng tôi nhận thấy một số điểm trùng lặp về triệu chứng và dấu hiệu giữa các mô hình TCM phổ biến đối với chứng mất ngủ Ví dụ, giấc ngủ bị rối loạn giấc mơ và chóng mặt có trong các mô hình phổ biến nhất So sánh các mẫu TCM với chẩn đoán mất ngủ theo phân loại của phương Tây hệ thống, chúng tôi phát hiện ra rằng chứng mất ngủ nguyên phát có thể kết hợp với chứng Thiếu cả tim và lá lách và chứng Tâm hỏa do thiếu âm; mất ngủ liên quan đến rối loạn lo âu tương thích với thiếu khí của tim và túi mật và gan-khí ngưng trệ chuyển hóa thành hỏa; mất ngủ liên quan đến rối loạn trầm cảm có thể giống như thiếu Qi của tim và túi mật; trong khi mất ngủ do tắc nghẽn hội chứng ngưng thở khi ngủ có một số điểm tương đồng với Thiếu cả tim Kết luận: Chúng tôi đã xác định được một số dạng hội chứng TCM phổ biến liên quan đến chứng mất ngủ đáng được nghiên cứu thêm, đặc biệt, chứng tim-thận không được liệt kê trong Sách giáo khoa về bệnh TCM Một số triệu chứng liên quan đến giấc ngủ bao gồm giấc ngủ bị rối loạn giấc mơ và giấc ngủ không yên không được sử dụng thường xuyên trong các hệ thống chẩn đoán phương Tây, nhưng thường được đề cập trong hệ thống bệnh TCM. Cần phải xem xét thêm tầm quan trọng lâm sàng của các triệu chứng liên quan đến giấc ngủ. Đánh giá của chúng tôi cho thấy rằng nhiều thuật ngữ Trung Quốc khác nhau đã được sử dụng trong tài liệu về TCM để mô tả hiện tượng tương tự

Trang 4Abstract
Objective: Previous reviews regarding Traditional Chinese Medicine (TCM) diagnosis
for insomnia were either limited to non-systematic search of Chinese language
literature or a particular TCM syndrome pattern A comprehensive review of Chinese
and English language literatures was therefore conducted to review the classification
of insomnia using TCM diagnostic system
Methods: We performed systematic review of all studies on insomnia that used TCM
diagnostic system Two independent researchers were responsible for paper retrieval
At the second phase, data from the final set of relevant papers was extracted using a
standardized data extraction form
Results: The search yielded 4795 potential articles titles; after going through our
inclusion and exclusion criteria for paper selection, a total of 103 studies and 9499
insomniac subjects were included in the second phase review We found a total of 69
different TCM syndrome patterns for insomnia The most common pattern was
Deficiency of both the heart and spleen, which was mentioned in 93.2% of the articles,
followed by Hyperactivity of fire due to yin deficiency (63.1%), Liver-qi stagnation
transforming into fire (42.7%), Internal disturbance of phlegm-heat (34.0%), Heart-kidney noninteraction (30.1%) and Qi deficiency of the heart and gallbladder
(29.1%) Although only 5 TCM diagnostic patterns are listed in the standard TCM
textbook, our review suggested that Heart-Kidney noninteraction, which was not
listed in the standard textbook, was ranked between second to sixth commonest TCM
diagnostic patterns by different selection criteria We found 23 different terms for
sleep-related symptoms and 89 different non-sleep-related symptoms associated with
the TCM syndrome patterns for insomnia The most common sleep-related symptoms
Trang 5in the TCM literature were dream-disturbed sleep, easy awakening from sleep and
restless sleep The most common non-sleep-related symptoms were dizziness,
palpitation and poor memory There were also tongue and pulse features mentioned in
the TCM literature We found some overlaps in symptom and sign among the
common TCM patterns for insomnia For example, dream disturbed sleep and
dizziness were present in 5 of the 6 most common patterns Comparing TCM patterns
with insomnia diagnoses in the Western classification systems, we found that primary
insomnia can probably be matched with Deficiency of both the heart and spleen and
Hyperactivity of fire due to yin deficiency; insomnia related to anxiety disorders is
compatible with Qi deficiency of the heart and gallbladder and Liver-qi stagnation
transforming into fire; insomnia related to depressive disorder may resemble Qi deficiency of the heart and gallbladder; while insomnia due to obstructive sleep apnea
syndrome has some similarities with Deficiency of both the heart
Conclusion: We identified some common TCM syndrome patterns related to insomnia
that were worthy of further studies, in particular, Heart-Kidney noninteraction, which
was not listed in the TCM textbook Some sleep-related symptoms including dream
disturbed sleep and restless sleep are not frequently used in the Western diagnostic
systems, but are commonly mentioned in the TCM system It is worthwhile to further
examine the clinical importance of those sleep-related symptoms Our review showed
that many different Chinese terms were used in the TCM literature to describe similar
phenomenon This lack of standardization in the terminology can definitely affect the
scientific studies of TCM Lastly, we found some similarities between the TCM and
Western classification for insomnia Further studies are needed to examine the
integration of TCM and Western classification systems in the diagnosis of insomnia
disorder

Introduction
1.1 Definition of insomnia
According to the American Academy of Sleep Medicine Work Group, the research
diagnostic criteria for insomnia include one or more of the following sleep related
complaints: difficulty initiating sleep, difficulty maintaining sleep, waking up too
early or sleep that is chronically nonrestorative or poor in quality The above sleep
difficulties occur despite adequate opportunity and circumstances for sleep Moreover,
at least one or more of the following forms of daytime impairment related to the
nighttime sleep difficulties are reported by the individual: fatigue or malaise; attention,
concentration or memory impairment; social or vocational dysfunction or poor school
performance; mood disturbance or irritability; daytime sleepiness; motivation, energy
or initiative reduction; proneness for errors or accidents at work or while driving;
tension headaches and/or gastrointestinal symptoms in response to sleep loss; and
concerns or worries about sleep1
In the revised edition of the International Classification of Sleep Disorders (ICSD),
more than 100 differential diagnoses of insomnia are listed 2 The recent report of the
American Academy of Sleep Medicine Work Group found that several insomnia
phenotypes that appear most valid and defensible1 Standardized research criteria for
the most valid phenotypes are developed, which include primary insomnia, insomnia
due to a mental disorder, psychophysiological insomnia, paradoxical insomnia,
Trang 12idiopathic (childhood onset) insomnia, insomnia related to periodic limb movement
disorder, insomnia related to sleep apnea, insomnia due to medical condition, and
insomnia due to drug or substance2
1.2 Epidemiology of insomnia
Concluding from more than 50 studies of insomnia based on data collected in various
representative community-dwelling samples,about one-third of the general population
presents at least one of the insomnia symptoms3.If daytime consequences of insomnia
are taken into account, the prevalence of insomnia is between 9% and 15%3 The
prevalence of insomnia disorder according to the Diagnostic and Statistical Manual of
Mental Disorders, Forth Edition (DSM-IV) criteria is roughly 6% 3.Moreover, there is
a trend of increasing insomnia symptoms with age; women are shown to have a higher
prevalence of insomnia than men 3
1.3 Traditional Chinese Medicine (TCM) theory of insomnia
TCM is one of the longest history medical systems in the world Over the past two
thousand years, the TCM medical system has become more conceptual and less
technologically driven while the TCM treatment becomes more individualistic than
Western medical therapies The TCM theory originates from doctors’ experience on
patients in ancient times 4; some TCM diagnostic issues regarding insomnia are not
considered in Western medicine theory
In term of the TCM theory, insomnia is due to a disharmony of Yin and Yang in their
Trang 13daily cycle in human body Quoting from chapter 80 of “Spiritual Axis” in “Huang Di
Nei Jing”: “If Defensive Qi does not enter into Yin at night and remains in Yang,
Yang-Qi will become full and Yang Qiao Mai in excess, Yin becomes deficient and the
eyes cannot close.”5 There is physiological decline of Qi and Blood in the elderly;
they normally have less sleep than younger people Chapter 18 of “Spiritual Axis” in
“Huang Di Nei Jing” says: “Young people have abundant Qi and Blood … they are
energetic in the daytime and sleep well at night Old people have declining Qi and
There are other quotes in TCM literature mentioned about sleep disturbances Chapter
34 of “Simple Questions” in “Huang Di Nei Jing” says: “If Stomach is not in peace,
sleep will not sound.”6 Body position also has a significant implication in sleep If a
person could not sleep in a supine position, it means an excess condition, usually the
Lung or Heart Chapter 46 of “Simple Questions” in “Huang Di Nei Jing” says: The Lung is the “lid” of the other organs When Lung-Qi is in excess, the Channels and Blood Vessels are full and the person cannot lie on his back This condition often
occurs in asthma patients, for example, when the Lung is obstructed by Phlegm If a
person can only sleep on one side, it indicates that there is either a deficiency of Qi
and Blood on that side of the body or an excess Qi and Blood on the opposite side
This condition especially applies to problems related to the Heart or Lung and can be
checked by testing the pulse By rolling the finger medially and laterally on the Lung
pulse, one can feel the state of Qi in right (lateral) and left (medial) Lung If there is
an imbalance in pulse, the person is only able to sleep on the Deficiency side 6
In term of TCM theory, noisy breathing is usually due to Phlegm affecting the
Trang 14Stomach Channel or caused by rebellious Qi in the three Yang Channels of the leg
Chapter 34 of “Simple Questions” in “Huang Di Nei Jing” says: “Those who suffer
from rebellious Qi cannot sleep well and have noisy breathing; this is due to
rebellious Qi in the Yang Ming Channels When the Qi of the three Yang Channels of
the leg cannot flow down and rebels upwards, it causes insomnia and noisy
breathing.”6
Sleep problems are mentioned in TCM literatures two thousand years ago5-6 TCM is
largely based on philosophical concepts Sophisticated and interconnected systems
work in balance to maintain the healthy function of the human body5-6 Although most
of the TCM concepts cannot be proven by scientific methods, the diagnostic system of
the TCM continues to be practiced nowadays
1.4 TCM diagnostic approach
TCM diagnostic process relies entirely on recognition of clinical symptoms by the
practitioners The use of technological aids to verify the findings is seldom necessary
The two diagnostic approaches in TCM are “disease differentiation” and “syndrome
differentiation”7 Disease differentiation aims to identify different diseases, for
example, stroke, diabetes, frozen shoulder or insomnia disorder Syndrome
differentiation aims to identify different patterns of disease and provide specific
treatment plan There are four diagnostic techniques - observation, auscultation and
olfaction, interrogation and palpation7 Practitioners discern subtle symptoms and
signs, and describe patients’ disharmony using the TCM diagnostic pattern that most
interferes with optimal state of wellness7
Trang 151.5 Syndrome differentiation
Syndrome differentiation describes patients’ disharmony in term of eight parameters:
diagnostic patterns are given by a combination of the above eight parameters and
others principles, such as Qi, Blood and Body-fluid differentiation, Zang Fu Organ
differentiation7 Using these different parameters and principles, the TCM syndrome
diagnostic pattern can be worked out Overall, the TCM diagnosis is characterized by
its comprehensive symptom-based approach and emphasis on imbalance of body
elements and functional status Because the diagnosis is based on the presence of a
group of subtle symptoms and signs, changes in only one symptom or sign can alter
the diagnostic pattern In addition, the TCM diagnostic pattern can change over time8
Yin and Yang are complementary opposites within a greater whole Everything has Yin
and Yang aspects that constantly interact and never exist in absolute stasis Yin and
Yang have several properties: opposing to each other, rooted together, transformed to
each other, and are in a dynamic equilibrium External refers to skin and hair while
Internal refers to internal organs, bone marrow, Qi and blood Excess is usually
caused by pathogenic factors; while Deficiency refers to dysfunction or lowering of
body function Hot refers to heat due to Yang excess or Yin Deficiency; while Cold
can be due to Yang Deficiency or Yin Excess7
1.6 Qi, Blood and Body-fluid Differentiation
Trang 16According to TCM theory, Qi refers to the essential energy flow that maintains the
vital body function If Qi is Excess or Deficiency, it may cause energy-related
disorders Disorder of the flow of Qi may cause stagnation, which can transform into
Blood is the most important nutrient that maintains vital body function According to
TCM theory, Spleen produces Blood and is responsible for the normal function of
Blood Blood is stored in the Liver, while Heart governs Blood Vessels The pathology
of Blood includes Blood Deficiency, Blood Stasis and Bleeding9
Body-fluid includes Phlegm and Fluids Phlegm can be tangible or intangible The
symptoms of Phlegm Excess may include chest oppression, gastric fullness, nausea,
vomiting, diarrhea, vertigo, palpitation, skin numbness, joint swelling, subcutaneous
lumps and mania Phlegm Excess results from dysfunction of the Lung, Spleen and
Kidney or Fire due to Yin Deficiency of the Zang Fu organs After mixing with Qi,
1.7 Zang Fu organs Differentiation
Zang Fu organs are consisted of five “Zang” and six “Fu” The five “Zang” refers to Liver, Heart, Spleen, Lung and Kidney, while the six “Fu” refers to Large intestine, Small intestine, Gall bladder, Stomach, Urinary bladder and Pericardium The
common sleep abnormalities involve dysfunction of Spleen, Stomach, Liver,
Trang 17Spleen and Stomach work together to generate Qi and Blood from food Spleen
controls Blood and governs the transportation and transformation of the water, food
and body fluids Spleen-Qi Deficiency may cause bleeding and retention of water
(tangible or intangible) Stomach governs the intake and decomposition of food
Either dysfunction of Spleen or Stomach can cause malnutrition of the body Worry,
over thinking, overwork will harm the Spleen and Stomach 9
Liver governs the flow of Qi Emotional distress can cause damage to the Liver
Chronic Liver-Qi stagnation, Liver-Blood Deficiency, Liver-Yin Deficiency, Liver-Fire
and Liver-Yang Excess are common Liver problems that cause insomnia9
Phlegm Fire and Gallbladder-Qi Deficiency are common causes of insomnia caused
by Gallbladder problem Gallbladder Overact may cause Fire, while Fire consumes
Fluids and produces Phlegm Phlegm-Fire always disturbs the Heart, which results in
insomnia Gallbladder is responsible for decision making Gallbladder-Qi Deficiency
may cause difficulty in decision making, which may cause insomnia Gallbladder is
attached to the Liver; hence problems of Liver may lead to Gallbladder problems9
Kidney is considered as the congenial base, which stores the primordial Yin and Yang
and Essence that are essential for the human growth Constitutional weakness,
overstrain, and malnutrition due to chronic disease will damage the Yin, Yang and
Essence of the Kidney The pathology of Kidney includes Kidney-Qi Deficiency, Kidney-Yin Deficiency, Kidney-Yang Deficiency and Kidney-Yin-Yang Deficiency and
Trang 18Heart governs Blood Vessels and stores the Mind Pericardium is the outside
protection of the Heart; hence it is sometimes attacked by exogenous pathogenic
factors, e.g., insomnia occurring after a contagious disease is always caused by
residue of pathogens in the Pericardium Heart Deficiency mostly refers to Heart-Yin
1.8 Classification of insomnia using TCM diagnostic system
The recognition of insomnia as a major medical problem by TCM practitioners has
been more than 2000 years The first written text about insomnia is Huang Di Nei Jing
first published around 100B.C , insomnia was classified as the disharmony of Yin and
Yang, disharmony in stomach, due to aging or secondary to other diseases such as
cough, vomit 5-6 Zhang Zhongjing (~220) classified insomnia into two types:
External and Internal 10 Dai Yuenli (~1400) states insomnia mainly classified into two
types, first type is due to sickness or Yang Deficiency caused by aging, second type is
due to Disturbance of phlegm in Gall bladder causing Deficiency in Heart Qi 11
Zhang Jiebin (1624) classified insomnia into with or without exogenous factors,
insomnia caused by exogenous factors mostly are expressed in excess syndrome and
for all insomnia not caused by exogenous factors are expressed in deficiency
syndrome 12 Li Zhongzi (1637) first classified insomnia into five syndromes clearly:
Deficiency of Qi, Deficiency of Yin, Stagnation of Phlegm, Water distention, Stomach
insomnia found that there were 45 possible TCM syndrome patterns14 The standard
textbook Traditional Chinese Internal Medicine recommended by the Ministry of
Health of China listed five TCM syndrome diagnostic patterns of insomnia9 Another
Trang 19standard textbook Internal Medicine of Traditional Chinese Medicine also listed five
TCM syndrome diagnostic patterns15; however, the two standard textbooks used
different terminology for the diagnostic patterns The five TCM syndrome diagnostic
patterns listed in Traditional Chinese Internal Medicine are Liver-qi stagnation
transforming into fire, Internal disturbance of Phlegm-Heat, Deficiency of both the heart and spleen, Hyperactivity of fire due to yin deficiency and Heart-gallbladder qi Deficiency The first two syndrome diagnostic patterns are Excess patterns, while the
other three are Deficiency patterns9
The common sleep problems of Liver-qi stagnation transforming into fire include
sleeplessness and dream disturbed sleep, while the common symptoms and signs are
irritability, thirst with desire to drink water, hypochondriac distension, poor appetite,
red face, bitter taste, constipation and bloody urine The tongue feature is red tongue
with a yellow coating, and the pulse is wiry and rapid The treatment principle is to
clear the Liver Fire and calm the Heart Mind 9
Regarding Internal disturbance of phlegm-heat, the common sleep problem is
sleeplessness Other common symptoms and signs include heavy sensation in the head
profuse sputum, chest stuffiness, nausea, belching, restlessness, bitter taste and
blurred vision The tongue features are red with a yellow and greasy coating The
pulse is slippery and rapid The treatment principle is to resolve Phlegm, clear Heat
and calm the Mind 9
The common sleep problem of Deficiency of both the heart and spleen is dream
disturbed sleep, while other common symptoms and signs include palpitation, poor
Trang 20memory, dizziness, blurred vision, weakness of the limbs, lassitude, poor appetite and
lusterless complexion The tongue features are pale tongue with thin and white
coating The pulse is thready and weak The treatment principle is to tonify the Heart
and Spleen, nourish Blood and calm the Mind 9
For Hyperactivity of fire due to yin deficiency, the common sleep problems are
restlessness and sleeplessness and other common symptoms and signs include
palpitation, uneasiness, dizziness, tinnitus, poor memory and weakness in the lumbar
region and knee joints, feverish sensation in the palms, soles and chest, and dry mouth
The tongue is red with scanty coating The pulse is thready and rapid The treatment
principle is to nourish Yin, reduce Fire, nourish the Heart and calm the Mind 9
The common sleep problems of Qi deficiency of the heart and gallbladder are
sleeplessness, dream disturbed sleep and frequent waking with a start Other common
symptoms and signs are timidity, palpitation, susceptibility to fright, shortness of
breath, lassitude and clear and profuse urine The tongue is pale and the pulse is wiry
and thready The treatment principle is to supplement Qi, relieve fright and calm the
Mind 9
There are some problems with TCM syndrome diagnostic pattern, including the lack
of standardization in the terminology of symptoms and signs and the lack of
agreement between TCM practitioners in the presence or absence of specific
symptoms and signs Another problem is the lack of standardization in the
terminology of syndromes Overall, the agreement between practitioners in syndrome
diagnostic pattern and treatment recommendation remains uncertain
Trang 21TCM is one of the longest history medical systems in the world, however further
development is hindered by the lack of standardization in the terminology of
symptoms, signs and syndrome diagnostic patterns As many studies of TCM
diagnostic patterns on insomnia have been published in Chinese and English scientific
literatures, and have not been systematic reviewed, it is therefore worthwhile to
undertake a systematic review on the TCM diagnostic patterns of insomnia
1.9 Aim of study
We aimed to find out the most common TCM diagnostic patterns given by TCM
practitioners for subjects with insomnia and the core symptoms and signs agreed by
TCM practitioners for the TCM diagnostic patterns We would also compare the TCM
diagnostic patterns with the insomnia phenotypes of the Western diagnostic system
Trang 22Chapter 2
Methods
This systematic review used a 2-stage approach The first stage was to retrieve
relevant literatures and textbooks using a standardized search strategy The second
stage was to retrieve the information regarding TCM diagnostic issues of insomnia
using a standardized record form
2.1 Databases searched
We searched the English language literatures using computerized databases, including
the Cochrane Central Register of Controlled Trials (CENTRAL) (1999-2009),
MEDLINE (1966-2009), EMBASE (1980-2009), PsycINFO (1887-2009), PUBMED
(1948-2009), Dissertation Abstracts International (1861-2009), Cumulative Index to
Nursing and Allied Health Literature (CINAHL) (1982-2009), Allied and
Complementary Medicine Database (AMED) (1985-2009), National Center for
Complementary and Alternative Medicine (1991-2009), and National Institute of
Health Clinical Trials Database (1997-2009) The keywords used were “Chinese
Medicine or TCM or acupunc* or acupress* or electroacupunc* or meridian* or
acupoint* or tuna*” and “sleep* or insomnia* or wakeful* or sleepless* or
somnambul*” The reference lists of the retrieved papers were further searched for
relevant articles
Trang 23We searched the China Journals Full-text Database from inception in 1915 to
November, 2008 Equivalent Chinese terms that were used to search the English
language databases are “中醫 or 中藥 or 針 or 推拿 or 穴 or 經絡 or 證型 or
診斷 or 辨證 or 分類” and “失眠 or 不寐 or 不得臥 or 睡眠困難” The China Journals Full-text Database was one of the major Chinese language literature
databases containing over 1143 medical journals including 129 major TCM journals
The reference lists of the retrieved papers were further searched for relevant articles
Studies included in this review were clinical trials that examined participants with
chief complaint of insomnia who have been classified with TCM diagnostic patterns
The participants using TCM treatments, placebo, Western medication or no treatment
will be included We did not set any specification for the treatments, outcome
measures, study quality and validity for our review
2.2 Paper selection process
The authors (M.K.P and H.K.Y.) searched the databases and independently examined
titles and abstracts of the retrieved papers and selected all potentially relevant
publications The investigators were not blind to the authors’ name and affiliation, or
journal name Full paper of the relevant publications were obtained and reviewed in
details against the inclusion and exclusion criteria We included all studies involving
participants with a chief complaint of insomnia The exclusion criteria were: (1)
discussion papers or magazine articles; (2) studies with less than 30 subjects; (3)
studies of male or female only; (4) studies that focus on a specific medical and
psychiatric condition; (5) studies that focus on a particular life transition period; (6)
Trang 24studies that focus on subjects aged >70 or <18 years; (7) studies that focus on a
specific TCM diagnostic pattern; (8) studies without statistical information regarding
TCM diagnostic pattern; and (9) duplicate publications reporting the same group of
participants The authors then discussed the selected articles; any disagreement about
the eligibility of articles was resolved by consensus and a final set of relevant papers
was confirmed
We have excluded those papers on either sex, specific medical/ psychiatric conditions,
life transition period and a specific TCM pattern were excluded in order to obtain a
representative picture of the frequency of various TCM syndrome for insomnia
Further studies may be needed to examine specific diagnostic pattern in specific
patient groups
2.3 Data extraction process
At the second phase, data from the final set of relevant papers was extracted using a
standardized data extraction form Study design, diagnostic criteria, participants’
characteristics including mode of recruitment, sampling procedure, inclusion and
exclusion criteria, number of subjects, age and sex distribution, duration of insomnia
and TCM diagnostic patterns including types of TCM diagnosis, symptoms of each
TCM diagnosis were extracted All Chinese to English translations in this paper were
deduced from the book Traditional Chinese Internal Medicine published by People’s
Medical Publishing House in 20079 and WHO International Standard Terminologies
on Traditional Medicine in the Western Pacific Region published by World Health
Organization in 200716
Trang 25Chapter 3
Results
3.1 Excluded papers
The search yielded 4795 potential articles titles for review; of which 1058 articles
were duplicate papers (Figure 1) A total of 1972 articles were excluded for reasons of
irrelevancy to insomnia or TCM; while 336 articles were excluded due to non-study
design Among the remaining 1423 studies, 95 studies with subjects aged below 18 or
above 70 years, 33 studies focus on either male or female only, 73 studies focus on a
specific medical and psychiatric condition, and 19 studies focus on a particular life
transition period There were 145 papers focusing on a specific TCM diagnostic
pattern, 264 papers with less than 30 subjects, and 364 studies without specific TCM
diagnostic patterns In addition, 16 papers were written neither in Chinese nor English,
310 studies without statistical information regarding TCM diagnostic pattern, and 1
paper could not be retrieved in full text A total of 103 studies were included in this
review17-119 Full details of the excluded studies are available from the authors upon
request
3.2 Description of the included studies
Table 1 presents the characteristics of the 103 reviewed studies17-119 Sample size of
the studies ranged from 30 to 856, with a total of 10035 subjects A total of 56.5% of
the sample was female The mean age of the subjects was 44.0 years, based on the 51
Trang 26studies that had the demographic data The duration of insomnia reported in the
reviewed studies ranged from 3 days to 51 years The 103 reviewed studies were all
conducted in China; only 5 studies (4.9%) were published in English language
literature
3.3 Types of study
Twenty-six (25.2%) of the 103 reviewed studies were RCT, 12 (11.7%) were
controlled non-randomized studies, 16 (15.5%) were case studies, 48 (46.6%) were
uncontrolled trials, and 1 (1.0%) was an epidemiological study
3.4 Types of journal
The 103 reviewed studies were published in 63 different journals; 7 studies were
extracted from English computerized databases, 96 studies were extracted from China
Journals Full-text Database Fifty-two of the 63 journals (82.5%); of which 85
reviewed studies were published, were known to have impact factor; while 17 journals
had impact factor higher than 0.5120
3.5 Diagnosis of insomnia disorders
Ninety-nine of the 103 reviewed studies (96.1%) had not used structured interview,
questionnaires, or polysomnography for the assessment of insomnia disorder Only 4
studies27, 65, 69-70 reported the use of standardized assessment procedure Gao27 and
Shi65 used the Pittsburgh Sleep Quality Index (PSQI)121 to assess the severity of
Trang 27insomnia Tian70 used the Spiegel Sleep Questionnaire122 Tang69 used
polysomnography for diagnosis and assessment of insomnia
Table 2 presents the diagnostic criteria for insomnia used in the reviewed studies
Sixty-nine of 103 studies (67.0%) mentioned that TCM diagnosis was based on the
criteria of a particular textbook Twelve of the 103 studies (11.7%) used the insomnia
criteria of the Diagnosis and Therapeutic Effect of Diseases and Syndromes in
Traditional Chinese Medicine (TCM-NJ) published by the State Administration of
Traditional Chinese Medicine of the People’s Republic of China123, which include: (1)
either difficulty falling asleep, frequent awakening, or difficulty falling asleep after
awakening, and (2) the sleep disturbance is the patients’ major concern and is
associated with daytime consequences The TCM-NJ criteria further classifies
insomnia into different subtypes based on TCM theory
Eleven of the included studies (10.7%) used the criteria for insomnia in the Chinese
Classification of Mental Disorder (CCMD) published by the Chinese Psychiatric
Association124, which include: (1) either difficulty falling asleep, frequent dreaming or
early awakening that occurs at least three nights per week for at least 1 month, and (2)
the sleep disturbance is the patients’ major concern and is associated with daytime
consequences
Nine studies used the Clinical Research Guidelines of New Chinese Herbal Medicine
(CRG) for diagnosis of insomnia; it includes a quantitative criterion of total sleep time
less than five hours per day and classifies insomnia into different subtypes based on
TCM theory125 One study used both the CCMD and CRG as diagnostic criteria, two
Trang 28studies used Hollister Diagnostic Criteria126, one study used the diagnostic criteria
published by the World Health Organization and one of the TCM textbook -
report the diagnostic criteria used None of the studies used DSM-IV criteria for
diagnosis of insomnia disorders Although both TCM-NJ and CRG criteria use
quantitative measures to define insomnia, the rest of their criteria are no different
from other traditional TCM diagnostic criteria
3.6 TCM syndrome diagnostic patterns mentioned in the reviewed papers
A total of 74 different TCM syndrome patterns were reported in the 103 reviewed
papers The number of TCM syndrome patterns used in individual study varied from 2
to 7 We found that some syndrome patterns were similar, for example, Heart
deficiency with timidity (心虛膽怯) and Heart-gall bladder deficiency and timidity
(心膽虛怯) After grouping similar TCM syndromes as one single syndrome, we
found 69 different TCM syndrome patterns as etiology of insomnia Table 3.1 shows
the 10 most common TCM syndrome patterns The six most common patterns were
Deficiency of both the heart and spleen (93.2%), Hyperactivity of fire due to yin deficiency (63.1%), Liver-qi stagnation transforming into fire (42.7%), Internal disturbance of phlegm-heat (34.0%), Heart-kidney noninteraction (30.1%) and Qi deficiency of the heart and gallbladder (29.1%)
3.7 TCM syndrome diagnostic patterns in RCT study design papers and papers
published in high impact factor journals
Trang 29We found 28 different TCM syndrome patterns mentioned in the 26 included papers
with RCT study design In order to compare the number of TCM syndrome patterns
for insomnia in RCT study design papers vs non-RCT papers, we randomly selected
26 of the 77 non-RCT papers for the comparison We found 34 different TCM
syndrome patterns, which was slightly greater than the number of TCM patterns in
RCT papers Table 3.2 presents the 12 most common TCM syndrome diagnostic
patterns reported in the RCT papers The six most common patterns were Deficiency
of the heart and spleen (92.3%), Hyperactivity of fire due to yin deficiency (61.5%), Liver-qi stagnation transforming into fire (50.0%), Heart-kidney noninteraction
(38.5%), Internal disturbance of phlegm-heat (34.6%), Heart deficiency with timidity
(23.1%) and Qi deficiency of the heart and gallbladder (23.1%)
Researches of the high quality papers and RCT studies were probably more stringent
in the diagnostic process; hence, they tend to follow the major diagnostic system with
the hypothesis number of TCM syndrome less than other papers Table 3.3 presents
the top 11 TCM syndrome diagnostic patterns in the 17 papers that were published in
journals with impact factor ≥0.5 We found that the papers with impact factor ≥0.5 had included 32 TCM syndrome diagnostic patterns In order to compare the number
of TCM syndrome patterns for insomnia in papers with impact factor ≥0.5 vs papers with no impact factor or impact factor <0.5, we randomly selected 17 of the 86 papers
with no impact factor or impact factor <0.5 for the comparison We found 16 different
TCM syndrome patterns in the papers published in journals with no or low impact
factor, which was much less than that the number of syndrome patterns in papers with
impact factor ≥0.5 The six most common TCM syndrome patterns in the papers published in journals with impact factor ≥0.5 were Deficiency of both the heart and
Trang 30spleen (94.1%), Heart-kidney noninteraction (52.9%), Hyperactivity of fire due to yin deficiency (41.2%), Liver-qi stagnation transforming into fire (35.3%), Qi deficiency
of the heart and gallbladder (29.4%) and Internal disturbance of phlegm-heat
(23.5%)
3.8 TCM syndrome diagnostic patterns in subjects with insomnia
A total of 9499 subjects in the reviewed studies had data on their TCM syndrome
diagnostic patterns Table 3.4 presents the 10 most common TCM syndrome patterns
in subjects with insomnia The most common pattern was Deficiency of both the heart
and spleen, which was diagnosed in 2365 subjects (25.0%), followed by Hyperactivity
of fire due to yin deficiency (17.1%), Liver-qi stagnation transforming into fire (9.7%), Heart-kidney noninteraction (8.1%), Qi deficiency of the heart and gallbladder (5.7
%), and Internal disturbance of phlegm-heat (4.9%) About 70% of the subjects were
diagnosed with Deficiency of both the heart and spleen, Hyperactivity of fire due to
yin deficiency, Liver-qi stagnation transforming into fire, Heart-kidney noninteraction, Internal disturbance of phlegm-heat, or Qi deficiency of the heart and gallbladder –
the 6 most common syndrome diagnostic patterns; and roughly 10% of the subjects
were diagnosed with the next 5 most common syndrome patterns
Table 4 shows a summary of the top 10 TCM syndrome diagnostic patterns in
different types of paper The top 6 patterns were the same regardless of the type of
papers, namely Deficiency of both the heart and spleen, Hyperactivity of fire due to
yin deficiency, Liver-qi stagnation transforming into fire, Heart-kidney noninteraction, Internal disturbance of phlegm-heat, and Qi deficiency of the heart and gallbladder
or Heart deficiency with timidity
Trang 313.9 Clinical features of the TCM syndrome diagnostic patterns
Thirty-seven reviewed papers had presented the symptoms and signs of individual
TCM syndrome diagnostic patterns Most of the terminology of the symptoms and
signs were in Chinese We translated all the Chinese terms to English Table 5
presents the sleep-related symptoms of the 6 most common TCM syndrome
diagnostic patterns There were a total of 51 different Chinese terminologies for
sleep-related symptoms; some of them appeared to be very similar For example, 入
睡困難, 不易入寐, 不易入睡, 難以入眠, and 難以入睡 were used to describe difficulty falling asleep After grouping some similar Chinese terminologies, the
number of terminology in English for the sleep-related symptoms was 23 We further
simplified the 23 different terminologies in English by grouping some similar terms,
for example, sometimes shallow sleep and shallow sleep, frequently wakes up with a
start and sometimes wakes up with a start, late night difficulty in falling asleep and
difficulty in falling asleep Finally, we found 21 terminologies in English for the
sleep-related symptoms The most frequently mentioned sleep-related symptom in the
TCM syndrome diagnostic patterns was dream-disturbed sleep (43.6%), followed by
easy awakening from sleep (34.3%), restless sleep (21.3%), and difficulty falling
asleep (13.9%)
There were a total of 158 different Chinese terminologies for non-sleep-related
symptoms; some of them also appeared to be very similar The number of different
terminologies in English for the non-sleep-related symptoms was reduced to 109 We
grouped some similar English terminologies, for example, little saliva and dry mouth,
Trang 32loss of strength and tiredness, reduction in luster complexion and lusterless
complexion Finally, we found 89 terminologies in English for the non-sleep-related
symptoms The most frequently mentioned non-sleep-related symptom was dizziness

feature was red tongue (50%), followed by pale tongue (36.2%), yellow coating
(29.6%), thin coating (26.9%), slimy coating (13.9%), scanty coating (11.1%), and
white coating (10.2%)

most frequent pulse feature was thready pulse (66.7%), followed by rapid pulse
(52.8%), weak pulse (28.7%), wiry pulse (25%), and slippery pulse (14.8%)

prescribed in subjects with insomnia and accounted for 8.1% among 9499 patients
complaining of insomnia (Table 3.4)
3.11 Comparing the clinical features among the top 6 TCM syndrome diagnostic
patterns
We found that some sleep-related symptoms, such as dream-disturbed sleep, restless
sleep, easy awakening from sleep were found in more than 1 TCM syndrome patterns
We found that dream-disturbed sleep was found in 5 of the 6 most common patterns,
except Heart-Kidney noninteraction; restless sleep was present in Internal
disturbance of phlegm-heat, Hyperactivity of fire due to yin deficiency, and Heart-kidney noninteraction; while easy awakening from sleep was present in Deficiency of both heart and spleen and Hyperactivity of fire due to yin deficiency
Trang 37Three sleep-related symptoms were only present in 1 pattern The symptom
sometimes shallow sleep was mentioned in Hyperactivity of fire due to yin deficiency,
difficulty falling asleep in Liver-qi stagnation transforming into fire and frequent
awakening with a start in Qi deficiency of the heart and gallbladder
Comparing the non-sleep-related symptoms among the top 6 TCM diagnostic patterns,
we found that dizziness, palpitation, restlessness, tinnitus, acid regurgitation, bitter
taste, blurred vision, oppression in the chest, poor memory, and feverish sensations in
the palms, soles and chest were present in more than 1 TCM syndrome patterns
Dizziness was present in 5 of the 6 patterns, except Qi deficiency of the heart and
gallbladder Palpitation was present in the 4 deficiency patterns Restlessness was
found in the 2 excess patterns, Hyperactivity of fire due to yin deficiency and
Heart-kidney noninteraction Tinnitus was present in Liver-qi stagnation transforming into fire, Hyperactivity of fire due to yin deficiency and Heart-kidney noninteraction Acid regurgitation, bitter taste, and oppression in the chest were
present in the 2 excess patterns Blurred vision was present in Internal disturbance of
phlegm-heat and Heart-kidney noninteraction Feverish sensations in the palms, soles
and chest were present in Hyperactivity of fire due to yin deficiency and Heart-kidney
noninteraction Poor memory was found in Deficiency of both the heart and spleen
and Hyperactivity of fire due to yin deficiency
Some symptoms were found in 1 pattern only Anguish in the heart, anorexia,
belching, heavy sensation in the head, profuse sputum and stuffiness in the stomach
were found in Internal disturbance of phlegm-heat Agitation, constipation, headache,
Trang 38hypochondriac distension, impatience, irritability, poor appetite, red face, reddish eyes,
thirst and yellow urine were found only in Liver-qi stagnation transforming into fire
Fatigue of the limbs, lack of strength, lassitude, reduction in luster complexion or
lusterless complexion and tasteless were present in Deficiency of both the heart and
spleen Emission of semen and night sweating were found in Heart-kidney noninteraction These 2 symptoms, emission of semen and night sweating were also
found in Hyperactivity of fire due to yin deficiency, but with a slightly different term,
emission of semen during dream and sweating Other symptoms only found in
Hyperactivity of fire due to yin deficiency were dry mouth or throat, scant fluid and
sore waist Prolonged and clear urine, shortness of breath, susceptibility to fright,
timidity and tiredness were found only in Qi deficiency of the heart and gallbladder
The tongue features of the 2 excess patterns were red tongue with yellow coating,
however, the tongue feature in Internal disturbance of phlegm-heat was different from
that in Liver-qi stagnation transforming into fire because the former pattern had a
slimy tongue coating Red tongue was also found in deficiency patterns with Yin
Deficiency, including Hyperactivity of fire due to yin deficiency and Heart-kidney noninteraction, but the former pattern had a scanty coating Pale tongue was present
in both Deficiency of both the heart and spleen and Qi deficiency of the heart and
gallbladder, but the former pattern had thin and white tongue coating
The pulse feature of the 2 excess TCM syndrome patterns was rapid pulse, while in
the 4 deficiency patterns; the pulse feature was fine pulse Rapid pulse also found in
the 2 Yin deficiency patterns, Hyperactivity of fire due to yin deficiency and Heart-
kidney noninteraction The pulse features of Deficiency of both the heart and spleen
Trang 39and Qi deficiency of the heart and gallbladder were different from those in other
deficiency patterns because the former had weak pulse, while the latter had wiry
pulse
3.12 TCM syndrome diagnostic patterns for insomnia vs Western insomnia
diagnoses
There are many diagnostic systems for insomnia, such as the DSM-IV, ICD-10 and
ICSD-2 This review only compared the TCM syndrome patterns with the DSM-IV
classification system We focused on 6 most common DSM-IV insomnia diagnoses,
namely, primary insomnia, substance-induced sleep disorder – insomnia type,
insomnia related to another mental disorder – anxiety disorders, insomnia related to
another mental disorder – depressive disorder, insomnia due to a general medical
condition, and insomnia due to specific sleep disorders, e.g OSAS, PLMD
Primary insomnia
Comparing the common TCM syndrome patterns of insomnia with the DSM-IV
primary insomnia, we found that difficulty initiating sleep was similar to difficulty
falling asleep in Liver-qi stagnation transforming into fire; difficulty maintaining
sleep in the DSM-IV system was similar to easy awakening from sleep in Deficiency
of both the heart and spleen and Hyperactivity of fire due to yin deficiency;
nonrestorative sleep was comparable to lassitude, lack of strength, fatigue of limbs in
also states that sleep disturbance and the associated daytime fatigue causes clinically
Trang 40significant distress or impairment in social, occupational, or other important areas of
functioning These daytime symptoms of primary insomnia are comparable to the
non-sleep-related symptoms in the TCM syndrome patterns The tongue and pulse
features mentioned in the TCM patterns are not reported in the DSM-IV primary
insomnia diagnosis As a whole, all common TCM syndrome patterns for insomnia
seem to be compatible with the DSM-IV primary insomnia diagnosis
Substance-induced sleep disorder – insomnia type
The DSM-IV diagnosis of substance-induced sleep disorder – insomnia type would
require the subjects’ sleep disturbance to be sufficiently severe to warrant independent
clinical attention and there is evidence from the history, physical examination, or
laboratory findings that the sleep disturbance is developed during, or within a month
of, substance intoxication or withdrawal; or medication use is etiologically related to
the sleep disturbance Moreover, the sleep disturbance causes clinically significant
distress or impairment in social, occupational, or other important areas of
functioning128 It seems that none of the common TCM diagnostic patterns for
insomnia mentioned about sleep disturbance associated with substances use We
concluded that none of the TCM syndrome patterns was compatible with the DSM-IV
substance-induced sleep disorder – insomnia type
Insomnia related to another mental disorder – anxiety disorders
The diagnostic criteria for insomnia related to another mental disorder – anxiety
disorders from DSM-IV 128 are basically the same as those for primary insomnia, but
