and scarring of the wound While SD-Ag offers a degree of

prevention of wound infection, it does so at the expense of

wound regeneration and tissue repair because SD-Ag

inhibits these healthy recovery processes In an effort to

reduce the negative consequences of SD-Ag on tissue

regeneration, a modification of SD-Ag application was

developed whereby more frequent applications in an

occlusive manner strove to enhance the retention of tissue

moisture However, when SD-Ag cream has been used at

an increased frequency to avoid wound desiccation, many

disadvantages occur including toxicity, and other side

effects of using SD-Ag have been reported These include:

transient leukopenia; sulfonamide hypersensitivity and

kernicterus; argyria; local reactions of burning, itching

and skin rash; delayed separation of burn eschar and

regeneration of epithelial cells resulting in an increase of

scar formation; increase of bacterial resistance, etc The

pharmacological mechanism of MEBO to treat burns

wounds is completely different from SD-Ag MEBO can

promote the regeneration of survival viable skin tissue

and cells, then accelerate wound healing by keeping burns

wounds in a three-dimensional physiological moist

envi-ronment while simultaneously facilitating the

liquefac-tion and discharge of necrotic tissues without causing

fur-ther injury to viable tissue MEBO achieves its infection

control by means of enhancing the resistance of local

tis-sue to infection in the context of an environment which is

no longer conducive to bacterial colonization and

prolif-eration Rather than exercising a direct bactericidal

ac-tion, MEBO changes the biological characteristics and

decreases the toxicity and invasive activity of bacteria

Therefore, we selected SD-Ag as a control to clarify the

irrefutably superior therapeutic effects of MEBO as

com-pared to the industry’s standards

Effects of MEBO on Burns Wounds Management

According to the results of this trial, MEBO promotes

burns wound healing for each depth of wound

Remark-ably, all of the deep partial-thickness burns wounds

healed spontaneously after treatment with MEBO,

there-by requiring no skin grafting The rate of scar formation

was also markedly reduced compared to that of the

con-trol group Furthermore, in this trial, more than half of the

clinically diagnosed full-thickness burns wounds could be

healed spontaneously by treating with MEBO throughout

the treatment procedure without requiring any skin

graft-ing Treatment with MEBO provided burns wounds an

optimum physiological environment for regeneration and

repair Subsequent to application of MEBO, the wound

would heal spontaneously without further damage to

via-ble tissue Therefore, the rates of scar formation,

deformi-ty and disabilideformi-ty were all significantly decreased

com-pared to those of the control group Meanwhile, it was

found that in the MEBO treatment group, the incidence

rate of wound infection was significantly reduced com-pared to that in the control group, indicating that MEBO

is capable of preventing wound infection

Analgesic Effect and Alleviation of Pain of MEBO

It was determined in this trial that throughout the treatment and during dressing changes, the analgesic ef-fect and alleviation of pain in the MEBO treatment group was dramatically superior to that of the SD-Ag control group Unlike SD-Ag which required painful peeling away

of crusted and dried dressing from fragile tissue, treat-ment with MEBO neither aggravated the suffering and pain sensation during the treatment and changing of dressing, nor did it fail to offer a satisfactory analgesic effect The need for an analgesic agent was rare in the MEBO-treated group

Feasibility of MEBO for Treating Extensive Burns Patients

In this trial, 75 extensive burns patients with TBSA 150% were treated by BRT with MEBT/MEBO which resulted in a 100% success rate whereby all patients were completely healed when discharged from the hospital No toxicity, side effects and local or systemic allergic reac-tions were found In contrast, 2 of 31 extensive burns patients in the SD-Ag control group died and 18 of them were discharged with some residual wounds Meanwhile, almost half of the extensive burns patients in the SD-Ag control group who were failing treatment due to complica-tions of wound infection, bleeding, severe painful or delayed healing were switched into the MEBO group for ethical reasons, and, despite the relatively late access to MEBO, these patients achieved the same satisfactory results Therefore, it was concluded that treatment with MEBO throughout the clinical procedure for extensive burns patients was both feasible and safe In addition, it indicated that when the treatment with SD-Ag for exten-sive burns patients appeared to be unsatisfactory, switch-ing them into a MEBO protocol was reasonable and ap-propriate MEBO seemed to promote spontaneous heal-ing in the delayed-healheal-ing wound and was able to prevent

or decrease the need for skin grafting

In conclusion, a clinical display of MEBT/MEBO on

treating superficial and deep partial-thickness burns is shown in figure 50 In figure 51, the clinical procedure and display of MEBT/MEBO on treating facial full-thick-ness burns can be seen Figure 52 is a clinical graphic report of the granulation tissue regenerating from burned bone wounds treated with MEBT/MEBO Finally, a case report on the treatment of electrical injury with MEBT/ MEBO is shown in figure 53

day after injury, most of the necrotic tissue has liquefied and dis-charged and the wound of deep partial thickness degree has started to

heal h On the 15th day after burn, most of the deep partial-thickness wounds is healed i On the 25th day after burn, the wound of deep

partial thickness degree has healed completely.

example of the process of wound liquefaction on day 12 postburn.

g On day 18 postburn, the necrotic tissues were almost liquefied and

painlessly discharged while subcutaneous tissues were allowed to

regenerate new skin h On day 27 postburn, some burns wounds

healed with complete regeneration while other burn lesions were in

the process of healing i On day 50 postburn, burns wounds healed

and skin regenerated physiologically Note the symmetrical smile and the lack of scarring Full sensation has returned.

e Appearance of tibial surface after drilling f Subsequent to the

appli-cation of preserved soaked MEBO gauze to cover the wound, within

a few days, small granulating buds grew up through the drilled holes.

g With continuous treatment with BRT, the granulation tissue

devel-oped and spread to form a granulated wound Skin grafting was then performed to close the wound.

Fig 53 a This case involved sustained

elec-trical injury to wrist and forearm The pic-ture shows necrosis of anterior forearm muscles, radial and ulnar arteries The in-terosseous artery was viable The pressure pain point of the upper extremity was at the

elbow b After 55 days of treatment with

BRT, the necrotic tissues were liquefied and discharged while the wound on

anteri-or wrist at the site of defective muscles was filled with granulation tissue The wound is now healing from its margins by epithelial

migration c In another case, a 9-year-old

patient was injured by a 150,00-volt electric impulse on the head The injury went deep

into the skull d Two days after the burn,

the wound was cleaned and the necrotic tis-sue removed, then multiple holes were drilled into the skull followed by treatment with bone BRT MEBO was applied

direct-ly onto the wound e Fifteen days after

treatment with MEBT/MEBO, small gran-ulating buds grew up through the holes.

f Twenty-two days of treatment with BRT and MEBT/MEBO, granulating tissue developed and spread to form a

granulated wound and the new epithelial skin island appeared g Follow-up picture 2 years later The wound was

healed and the skull was completely covered.

Remarkably, rigorous sterile conditions are not

re-quired if burns regenerative medicine and therapy

(MEBT/MEBO) is used in the care of extensive burns

patients Basic equipment and general surgical conditions

typically suffice However, ambient room temperature of

32–36° C and careful, well-trained, intelligent nursing

care are required so that removing liquefied product in a

timely manner is accomplished In general, surgical

prin-ciples of systemic comprehensive treatment should be

fol-lowed Figure 54a–e shows Prof Rong Xiang Xu,

inven-tor of burns regenerative medicine and therapy (MEBT/

MEBO), as he assesses and directs the treatment for a

burns patient with deep burns of TBSA 100%
