Objective To explore serratus anterior muscle transplantation for the repair of soft tissue defects in foot and ankle. Methods Seventeen patients consisted of 11 males and 6 females aging from 13 to 58 years with the mean age of 35.2 years. The anatomical parameters of serratus anterior of 17 cases were measured, the thickness of the muscle was (1.24?0.65) cm, and the diameter of origin point of the nutrient artery to the muscle was (1.4?0.6) mm. There were two veins arising from the muscle, the diameter of larger one was (2.5?0.8) mm. The length of vascular pedicle was (8.31?1.48) cm. 17 patients with soft tissue defect of foot and ankle were treated with free serratus anterior muscle transfer and split skin graft overlying the muscle. The primary lesions were soft tissue defect around the ankle and Pilon fracture in 5 cases, non-union of distal tibial fracture in 3, Achilles tendon and soft tissue defect in 3, metatarsal fracture and soft tissue defect in 4, and calcaneal fracture with soft tissue defect in 2. All of the patients suffered from infection or exposure of bone or applied plate, the area of soft tissue defect ranged from 4.5 cm?6 cm to 11 cm?13 cm. Results The average operative time was (6.5?1.2) hours. The complications included local hematoma in 2 cases, superficial infection in 2, winged scapula without function loss in 1,scar pain in 2, and numbness of lateral thoracic wall in 1. Furthermore, weakness and decreased shoulder mobility were noted in 3 patients comparing with the contralateral side, but the condition improved half year following the operation. The transferred muscle flap appeared thinner and less bulky , and healed intimately with the adjacent foot tissue, the patients resumed good function in walking. Conclusion The serratus anterior muscle flap is a good choice for treatment of soft tissue defects in foot and ankle.

ObjectiveTo evaluate intraoperative cholangiograhy during cholecystectomy for patients with preoperative benign gallbladder disease. Methods Unexpected biliary disease and anomaly found by intraoperative cholangiography in 904 cases of preoperatively diagnosed simple gallbladder stone and polypoid lesions were analyzed. Results Choledocholithiasis was found in 79 cases, anomalous pancreaticobiliary junction (APBJ)in 21, gallbladder cystic duct variations in 28, right accessory hepatic duct in 4 . Conclusions Intraoperative cholangiograhy during the process of simple cholecystectomy helps to discover preoperatively mis-diagnosed choledocholithiasis, hence to avoid secondary exploration of common bile duct which is otherwise inevitable, it may also demonstrate the anomalous pancreaticobiliary junction and bile ductal anatomic variations.

Objective To study the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) ,cy-clooxygenase-2 ( COX-2 ) inhibitor Piroxicam on the growth of colorectal cancer cells and to evaluate the preventive significance from COX-2 expression and apoptosis. Methods The cell growth of colorectal adenocar-cinoma cell line SW1116 was measured by MTT (3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl tetrazolium bromide) assay, and COX-2 protein expression by Immunohistochemistry and Western Blot. Apoptosis was characterized by DNA fragmentation. Results The results showed that COX-2 inhibitor Piroxicam could restrain the proliferation of SW1116, which had positively related to its concentration. Concentration higher than 1. 0mmol/L showed cytotoxic effects. The inhibition of COX-2 by Piroxicam appeared within 12 hours, but COX-2 protein level recovered within 24 hours, its expression had negatively related to the concentration of Piroxicam. Apoptosis was induced in SW1116 culture with Piroxicam higher than 0. 1mmol/L. Conclusion It can be concluded that cell inhibition effect is associated with Piroxicam-mediated cell apoptosis and inhibition of COX-2 protein expression in SW1116 cell, because the effects of Piroxicam have the concentration and time dependence, in further clinical research its dosage and time of medication should be considered in preventing or treating colorectal cancer.

Objective To investigate effect of guanosine diphosphate (GDP) on the mitochondrial respiratory oxygen consumption and the mitochondrial membrane potential (MMP) of rat brain and explore the relationship of the change of uncoupling proteins (UCPS) activity with the oxygen consumption and MMP. Methods The mitochondria of rat brain were isolated by centrifugation. Mitochondria oxidative respiratory consumption was measured by Clark electrode after the treatment of GDP at different concentrations so as to calculate mitochondrial state 3 respiration (ST3), mitochondrial state 4 respiration (ST4), respiratory control rate (RCR), and the rate of oxidative phosphorylation (OPR). MMP was detected by Rhodamine 123 method at the different concentrations of GDP. Results With the increase of GDP concentration form 0 to 1.0 mmol/L, the values of ST3, ST4 and OPR were reduced while RCR was elevated. But when the concentration increased to 1.4 mmol/L, the former 3 indexes begun to increase while the later declined. When the GDP concentration reached to 1 mmol/L, the inhibitory rate was only 35.1%, 51.3%, 14.2% to ST3, ST4 and OPR respectively, while RCR was increased to 133.2%. No matter the concentration was over 1 mmol/L or under 1 mmol/L, the ability of inhibition was attenuated. MMP reached to the highest point when GDP exerted the highest inhibitory rate on mitochondrial respiratory oxygen consumption. Conclusion GDP, an inhibitor of UCPS, can regulate the respiratory oxygen consumption and MMP of the isolated rat brain mitochondrial directly in a dose-effect fashion. The change of UCPS activity can affect the respiratory oxygen consumption and MMP.

Objective To explore the effects of glucocorticoid(GC)and lipid metabolism on the pathogenesis of avascular necrosis of femoral head(ANFH).Methods Thirty-two New Zealand rabbits were randomly assigned into two groups as experiment group(n=24)and control group(n=8).Each rabbit in experiment group was given injection with 8.0mg/kg of hydrocortisone acetate for two times per week,while rabbits in control group were given normal saline in same quantity.Serum glucocorticoid(GC)concentration,total cholesterol(TC)and triglyceride(TG)were determined respectively before and 2,4,6 and 8 weeks after treatment.Rabbits were sacrificed at the 2nd,4th,6th and 8th week.The rabbits,sacrificed at the same time point,were stratified into group A(low concentration group)and group B(high concentration group)according to the GC concentration,in an attempt to observe the rate of empty bone lacuna and glucocorticoid receptor(GR)expression in the soft tissue around hips.Results The concentration of TC of experiment group began to increase since the 6th week,and that of TG since 2nd week(P0.05).In addition,the rate of bone lacuna and OD scores of GR were positively correlated at the 4th and 8th week(r=0.699 0,0.605 0,P
