RESUMO
Skin is a kind of tissue that surrounds the surface of body, it is the first barrier for animals to resist mechanical, chemical and pathogenic microorganisms. Skin wound is one of the most common surgical diseases. The process of wound healing can be summarized as three stages: inflammation stage, fibrous tissue proliferation stage, and scar formation and repair stage. Incomplete repair of the wound leads to skin scarring, which causes the tissue to lose its normal structure and function, and seriously affects the aesthetic appearance. Traditional treatment methods can not restore the normal function of the skin and have obvious adverse reactions, which can not meet people's needs. Stem cell therapy, especially adipose derived stem cells (ADSCs) plays a essential rule in the process of wound healing making it a research hotspot in recent years. ADSCs can secrete a variety of growth factors during wound healing to reduce wound inflammatory response, promote wound regeneration epithelialization and vascular reconstruction, thereby promoting wound healing. In this paper, the wound healing process and its regulation mechanism were summarized, and the role of ADSCs in wound healing at home and abroad and its clinical application progress were reviewed.
RESUMO
Objective To investigate the changeof plasmadiponectin and N-terminal pro-brain natriuretipeptide (NT-proBNP) levelin the patientwith differentypeof atrial fibrillation (Af) .MethodTwo hundred and thirty-fouresearch sub-jectwere divided into 4 group:sinurhythm group (n= 70) ,paroxysmal Af group (n=52) ,permanenAf group (n=62) and control group (n=50) .The plasmadiponectin level wameasured by the enzyme-linked immunosorbenassay (ELISA) and the NT-proBNP level wadetected by chemiluminescence .4 groupwere comparable in age ,gende,body masindex and basidisea-se.ResultThe NT-proBNP level in the paroxysmal Af group and the permanenAf group wasignificantly increased compared with the sinurhythm group and the control group ,the difference wastatistically significan(P＜0 .05) ,buthe difference be-tween the sinurhythm group and the control group had no statistical significance (P＞0 .05) .The NT-proBNP level in the perma-nenAf group wasignificantly increased compared with the paroxysmal Af group (P＜0 .05) .Compared with control group ,the adiponectin level in the sinurhythm group wasignificantly decreased (P＜0 .05) ,which in the paroxysmal Af group and the per-manenAf group wasignificantly increased compared with the sinurhythm group and the control group ,the difference wastatis-tically significan(P＜0 .05) .The adiponectin level in the permanenAf group wasignificantly increased compared with the parox-ysmal Af group (P＜0 .05) .Conclusion The adiponectin level could be related with the repeated occurrence of permanen Af .
