Objective The clinical effect of the lateral femoral cutaneous artery flap for soft tissue defects of leg wounds. Methods From October 2007 to January 2016, VSD was firstly used to promote the growth of granulation tissue. When the growth of granulation tissue became satisfactory, flaps were designed based on the anatomical characteristics of the lateral femoral cutaneous artery. We repaired 20 cases of wound defects by cutting flaps that coincide with the recipient vessels. Result 20 cases were followed up for 6 to 24 months, 12 months on average. All flaps were survived and only one case had small area of necrosis flap which was healed by replacing medicines. In all cases, wounds were healed and flaps showed good color and good texture. The strength of quadriceps muscle was good and the extension of knee flexion was 0° to 150°. Conclusion To The lateral femoral cutaneous artery flap is used for soft tissue defects of refractory wounds on leg , flap donor sites are sutured directly, the treatment period is shorten and the method is safe and effective. The lateral femoral cutaneous artery flap is one of ideal choices for wound tissue defects.

Porcine interleukin-18 mature protein gene was amplified from porcine spleen cells by RT-PCR. PCR product was cloned into the T vector pGEM-T for sequencing. The nucleotide sequence of this gene was 474 bp. Then, it was subcloned into the prokaryotic expressing plasmid vector pGEX6P-1 and transformed into host E. coli strain BL21 for expression. The expression of pIL-18 mature protein gene was identified by SDS-PAGE .The expression product was fusion protein with molecular weight of 45 kD and the percentage of expression protein in E. coil protein was 28%. The protein was purified by washing of inclusion bodies and the activity was measured by methyl thiazolyl tetrazolium (MTT).

Primary liver cancer is one of the most malignant tumor in the worldwide.5 years recurrence rate of patients in the early phase is exceeding 70%.Recurrence of HCC is one of the vital factors leading to adverse outcomes.Researchers found that characteristics of tumors,such as tumor size,differentiation and vascular invasion;operation aspect,such as surgical margin width,surgical approach,intraoperative bleeding and transfusion;patient-self and liver transplantation related factors,such as liver disease,donor's age,hepatitis B virus infection of recipient can affect the postoperative recurrence of hepatocellular carcinoma.We summarized the influence factors of postoperative recurrence of HCC via literature review.

Postoperative complications of ERCP include pancreatitis,cholangitis,hemorrhage,mechanical damage (such as perforation) of the digestive tract and drug reaction.Since the the complications definition,surgical indications,operation technique,data collection and processing method were inconsistent,there were controversies for the incidences of complications after ERCP and its risk factors for different institutions.This paper discussed the evolution of ERCP risk factors,current situation and prophylaxis of major complications after ERCP and summarized the current research progress in order to provide theoretical help for prevention and prophylaxis of postoperative complications of ERCP.

Objective To investigate the effects of a 45%high-fat diet(HFD)with isocaloric intake on energy metabolism and endurance exercise capacity in SD rats.Methods Twenty-four male SD rats were randomly divided into normal chow diet group(CON),HFD group,normal chow diet+exercise training group(CONT),and HFD+exercise training group(HFDT).The CON and CONT groups received normal chow diet,while the HFD and HFDT groups received a 45%high-fat diet with isocaloric intake.The HFDT and CONT groups underwent an endurance training of moderate-intensity running for 6 weeks.Body weight,fat mass,and lean mass were measured weekly.Energy expenditure and basal metabolic rate during rest and exercise states were measured using Pheno Master/Calo Treadmill system.Blood glucose,lipids,and creatine kinase levels were detected after the exhaustion test.Results In 6 weeks after intervention,the endurance exercise capacity was significantly enhanced in the HFDT group than the CONT group(P<0.05).There were no obvious differences in body weight and body composition among the groups under isoenergetic feeding conditions.At rest,no statistical differences were observed in total energy expenditure and basal metabolic rate among the groups.However,prior to the 4th week,the CON group primarily metabolized carbohydrates while the HFD group primarily metabolized fats.But the carbohydrate metabolism was decreased and then increased,and the substrate metabolism rates eventually reached similar levels between the 2 groups on the 5th to 6th week.The HFDT group primarily metabolized fats while the CONT group primarily metabolized carbohydrates,with significant differences persisting after 6 weeks of training(P<0.05).HFD led to elevated levels of serum cholesterol,triglycerides(TG),and high-density lipoprotein cholesterol(HDL-C),but,endurance training resulted in decreased lipid levels in the HFDT group,accompanied by an increase inβ-hydroxybutyrate(βHB)level(P<0.05).Isoenergetic diets had no significant differences in their effects on liver and kidney function or muscle damage indicators.Conclusion An isoenergetic HFD can improve fat utilization ability and extend endurance exercise time in rats without altering body composition or affecting liver and kidney function.

Objective To develop a nutritional formula on enhancing the endurance of heavy load exercise,and evaluate its efficacy comprehensively.Methods Sixty C57BL/6J male mice were randomly divided into control group(CON group)and low-,medium-and high-dose nutritional formula groups(LDF,MDF and HDF groups),with 15 mice in each group.Each group received intervention with nutritional formula at corresponding dose for 2 weeks,and underwent adaptive training and heavy load exercise in the 1 st and 2nd weeks,respectively.Exhaustion exercise time,skeletal muscle antioxidant indicators(SOD,MDA,PC and GSH),fatigue related indicators(serum URA,LDH and LA),muscle glycogen,and serum exercise injury related indicators(ALT,AST,CK and CK-MB)were measured and detected in the mice,and comprehensive evaluation was conducted according to relevant evaluation standards.Results The LDF group,MDF group and HDF group had significantly prolonged running exhaustion time than the CON group(P<0.05),with the HDF group showing the greatest improvement(P<0.05).Compared with the CON group,the activities of SOD and GSH in the skeletal muscles were significantly increased(P<0.05),while the levels of MDA and PC in skeletal muscles were obviously decreased in the 3 doses of nutritional formula groups(P<0.05).PAS staining of the skeletal muscles displayed that the glycogen content was significantly increased in the MDF group and the HDF group than the CON group(P<0.05),and the highest increase was observed in the HDF group(P<0.05).Biochemical test revealed that the levels of LDH,LA,ALT,AST,CK,and CK-MB were remarkably lower in the 3 doses of nutritional formula groups than the CON group(P<0.05).Conclusion The nutritional formula can significantly improve the endurance and skeletal muscle antioxidant capacity in mice under heavy load exercise,and has anti-fatigue and-injury protection effects.This nutritional formula can be used to support physical fitness during heavy load endurance exercise.
