Objective To study the advantage and disadvantage of different treatments of unstable distal radial fractures in elderly patients. Methods In the period from August 2005 to January 2010, 55 elderly patients with unstable d istal radial fractures were treated with manual diaplasis and external plaster splint fixation, operation and internal plate fixation, or external fixation. Clinical outcomes were evaluated by Gartland-Werley wrist scoring systems and questionnaire of the disabilities of the Arm, Shoulder and Hand (DASH). We used SPSS13.0 software package for statistical analysis. Results Compared with the manual diaplasis group, the operation and internal plate fixation group or external fixation group was better in Gartland-Werley scores, the differences were statistically significant (P<0.05), but there were no differences in DASH scores among the 3 groups. Conclusions The treatment of unstable distal radial fractures in elderly patients should be chosen based on the characteristics of the fractare and patients desire.

Objective To observe the effect of depside salt from Salvia Miltiorrhiza on platelet endothelial nitric oxide synthase(eNOS) activity in health adults.Methods Peripheral venous blood was collected,platelets were isolated with gel-filtration chromatography and incubated with eNOS agonist histamine,eNOS inhibitor L-NAME and different concentrations of depside salt from Salvia Miltiorrhiza(0.1,1,10,100,1000 mg/L) for 30 minutes,then eNOS activity was measured as formation of 3H-L-citrulline from 3H-L-arginine.Results(1)Platelet eNOS activity was significantly inhibited after incubated platelets with L-NAME and increased after incubated with histamine(P

Objective To explore the role of inflammatory mediators in the pathogenesis of acute pancreatitis(AP).Methods Observation the relationship betweent the changes in serum TNF and IL-6 and(histopathology) of the pancreas in AP rats.Results(1)Rats in sham operation group survived throughout the experiment.Compared with of sham operation group,in AP group survival time shortened significantly(P

Objective To explore the role of apoptosis in the pathogenesis of acute pancreatitis(AP)and to (investigate) the effect of ligustrazin(LGT) on the apoptosis in acute pancreatitis .Methods Experimental animals were divided into three groups randomly: (1) AP group, (2) comparison group,and (3) therapy group. Pathologic score and TUNEL method were used to detect the pathologic mophology of pancreatic tissue and the pancreatic cell apoptosis index in the 3 groups. Results In the early stage of AP,the majority of cells are apototic and the degree of AP is slight.In the late stage of AP,the majority of cells show necrosis,and the degree of AP is severe.The (induction) of cell apoptosis can lessen the pathologic state of AP. Conclusions The degree of pathologic changes in AP can be lessened by the induction of cell apoptosis,but there is a definte time limit.

Objective To explore the changes of plasma endotoxin and D-lactate during intestinal mucosal barrier injury of acute pancreatitis.Methods Wistar rats were randomly divided into sham-operation(SO)group,and severe acute pancreatitis(SAP)group.Plasma endotoxin and D-lactate were determined at 1,3,6 and 12 hour after operations.Results The plasma endotoxin and D-lactate in SAP group increased obviously with time,and the difference betueen the 2 groups was significante(P

目的观察苁蓉通便汤治疗老年性便秘的临床疗效。方法将 62例老年性便秘患者分为两组。治疗组(32例)内服苁蓉通便汤,对照组(30例)内服麻仁润肠丸。结果治疗组疗效优于对照组(P<0.05)。结论苁蓉通便汤对老年性便秘疗效显著。

Objective To study a simple surgical method for continuous rapid tissue expansion and its clinical application. Methods The operation was accomplished in two-stage procedures. First, expanders were placed in the subcutaneous pocket through interlesional perpendicular short incisions. Continuous expansion by trace syringe pump began from the second day after expander placement. The speed of water injection was set according to patient's algesthesia reaction and vascularity of skin. The second operation was carried out at the third to fifth day after the expansion completed.Results The method was put into clinical practice in 22 cases (16 cases of scar, 2 cases of capillary angioma, and 4 cases of black nevus), and 35 expanders were placed. The speed of water injection was set in 0.2～0.8ml/hr/100ml.The mean time of water injection was 15.3 days. In the process of expansion, all cases were satisfactory except 1 case, in which the expander exposed in the incision. After the second operation, all flaps survived except one showing distal skin necrosis. The result was satisfactory after 3 months to 1 year follow-up. Conclusion The procedure consists of expander placement through interlesional perpendicular short incisions and continuous expansion in advance, which maximally shortens the time of expansion and hospitalization. This expansion method is a simple, safe, reliable, and ideal rapid tissue expansion technique.

The expression of transforming growth factor(TGF)-β supeffamily co-receptor (Tβ3R) Ⅲ is often lost in many kinds of cancers.Tβ3RⅢ plays a role of negative regulation in tumorigenesis.T3RⅢ could regulate the cellular invasion,migration,proliferation and apoptosis by multiple mechanisms,such as mediating the TGF-β signaling pathway,impacting the mitogen-activated protein kinase(MAPK),nuclear factor-kappa B (NF-κB) and Cdc42 and producing soluble TβR(sTβR) Ⅲ.Defining the mechanisms of absence and physiological functions of TβR Ⅲ in cancers has great significant for the diagnosis,treatment and prognosis of cancer.
