Objective To investigate the effective method of the treatment of the infective, complex defect of skin and bone in crus. Methods On the basis of through anti-infection, the infective surface of wound with bone and skin complex defect was completely debrided. The infective and necrotic skin and bone were moved away, and the wound surface was covered with flaps having abundant circulation. The anti-infection therapy was continued after operation. When the infection healed and the normal skin covered the wound, the bone defect was renovated at the second stage. Result The transplanted flaps all survived and the skin covering the wound remained normal. After the follow-up of four to five years, all the transplanted bones healed completely. No limbs were amputured because of wound infection or the complex defect of bone and skin. Conclusion After the infective surface of wound was completely debrided, the skin defect was renovated with flaps having abundant circulation. On the basis of infection being totally cured, the lone-piece-bone defect was renovated. This method can maintain the limbs and creat conditon for the functional recovery.

Objective To investigate the effects of radiotherapy combined with resveratrol( Res)on proliferation, invasion and apoptosis of hepatoma cell line Bel-7404. Methods Bel-7404 cell line was treated with Res(25 μmol·L-1 ) combined with radiotherapy,then divided into four groups( group 1:the control;group 2:radiation at dose of 2 Gy;group 3:radiation at dose of 4 Gy;group 4:radiation at dose of 6 Gy). Cell proliferation and invasion were detected by MTT assay. Cell apoptosis were observed by fluorescence microscopy. Expressions of MMP-2 and VEGF proteins were determined by Western blotting. Results Compared with the control group,cell proliferation and invasion were significantly inhibited,while cell apoptosis was increased in all radiation groups(P〈0. 05). Conclusion The sensitivity of hepatoma Bel-7404 cells to radiation can be enhanced by resveratrol. Radiation therapy combined with resveratrol can inhibit proliferation and invasion of hepatoma cells and increase the cell apoptosis,which may be related with the down-regulation of MMP-2 and VEGF proteins.

Success was obtained in all cases. The operative method, indication, selection of the skin donor area and the key factor of operative success were introduced and discussed in the article.

Objective To investigate the effects of acarbose versus fenofibrate on insulin secretion and insulin resistance in the subjects with impaired glucose tolerance (IGT) and hypertriglyceridemia. Methods Eighty subjects were allocated to acarbose group (28 cases),fenofibrate group (30 cases),and control group (22 cases) without intervention for 3 months,and also divided into elderly (46 cases) and younger groups (34 cases). Fasting blood samples were collected for measuring fasting plasma glucose and lipid.Oral glucose tolerance test (OGTT) were carried out with measurement of plasma insulin and glucose before ad after treatment.Early insulin secretion indexes(△I30/△G30),insulin secretion indexes (HOMA -β) and insulin resistance indexes (HOMA-IR)were calculated. Results After 3-months of treatment,the lipid profile was evidently improved in fenofibrate group. Levels of triglyceride (TG) and total cholesterol (TC) were significantly reduced ( both P ＜ 0.01 ),△I30/△G30 was significantly increased (P ＜ 0.05) and HOMA-IR was decreased (P＜＜0.01).In acarbose group,levels of fasting plasma glucose (FPG),2hours postprandial plasma glucose (2 hPG) and HOMA-IR were reduced (all P＜0.01),△I30/△G30 and HOMA-β were enhanced (P＜0.01 or P＜0.05).No change of above indicators was found in the control group.Compared with fenofibrate group,acarbose group had higher △ I30/△G30 (P＜ 0.05),HOMA-β (P＜ 0.01 ) and lower HOMA-IR ( P ＜ 0.01 ).The improvement of △△I30/△G30 was correlated with the decreasing of plasma FPG,2 hPG and TG(r=0.5812,0.6327,0.3872,P＜0.01),while HOMA-1R was related with the decreasing of plasma 2 hPG,TG and TC(r=0.8126,0.4671,0.2895,P＜ 0.01). HOMA-IR,△I30/△G30 and HOMA-β were lower (P＜0.01) and acarbose improved insulin resistance better (P＜0.05) in the elderly than in the younger with type 2 diabetes. Conclusions Pancreatic β-cell function declines gradually with aging,acarbose may have advantage over fenofibrate in improving early insulin secretion and resistance which was more relieved by diminishing glucotoxity in comparison with lipotoxity.
