Abstract：

Objective To discuss the influence of aerosol bioelectricity on the expression of interleukin (IL) -8 and IL-10 in wound healing of burned rats. Methods The deep Ⅱ degree scalding models were established in Sprague Dawley (SD) rats. Rats were randomly divided into experimental group (n1 =20) and control group (n2 =20). The rats in experimental group were treated with aerosol bioelectricity.Samples were collected at the first to eleventh day post-scalding. Immunohistochemistry and image analysis methods were conducted to examine the expression of IL-8 and IL-10 in both experimental and control groups. Results The average wound healing time in experimental group was 7. 00 ± 1. 15 days, and that in control group was 9. 00 ± 1. 34 days. IL-8 and IL-10 were observed mainly in polylmorphonuclear and mononuclear cells in both experimental and control groups on the 1 st day. On the third day, fibroblasts abounded, IL-8 expression was increased evidently and reached a peak. The peak value (6. 73 ± 1. 36) in experimental group was lower significantly than that in control group ( 2. 85 ± 0. 72, P ＜ 0. 01). From the 5th to 11th day, IL-8 expression was declined rapidly. IL-10 was expressed in keratode cells and had the peak value in experimental group (1. 24 ±0. 15) and control group (5. 69 ± 1. 32) on the 3rd day. IL-10 expression was declined gradually from the 5th to 11th days. The expression level of IL-10 in experimental group was significantly higher than in control group from the 3rd day to 11th days post-scalding (P＜0. 01). On the 3rd day, both IL-8 and IL-10 in experimental and control groups were expressed abundantly , and there was negative relationship between them (r = - 0. 862, P ＜ 0. 01). Conclusion Aerosol bioelectricity can indicate active cells proliferation through down-regulating the expression of IL-8 and up-regulating the expression of IL-10, accelerating burned wound healing.

更进一步提高深度烧伤创面修复质量

This article summarizes methods of repair of massive and deep wounds, elucidates how to improve wound healing quality and avoid scar deformity after deep hum. A part of denatured dermis (non-necrotic)in deep partial-thickness burn, "mixed degree" burn, even in full-thickness burn wounds before forming eschar can be preserved and covered with autolo-gous skin, thereby to avoid secondary damage to the structure of subcutaneous tissue and the junction of dermis-adipose, thus to result in good functions, appearance, and survival rate. After skin grafting, wound healing quality and appearance are im-proved, joint function and elasticity of skin are enhanced, the degree of scar contracture is relieved due to preservation of nor-mal adipose tissue after escharectomy. The study of composite artifical skin will be actively developed in the future. Tissue-en-gineering skin and stem cells can be successfully used in pa-tients with deep burns for starless healing with restoration of physiological functions in a short period.
