Objective To investigate the effect of medial collateral ligament reconstruction using semitendinosus autograft.Methods A total of 12 patients with medial collateral ligament injury received knee examinations.Among them,2 had lateral meniscus injury,and received partial resection of the lateral meniscus;2 had cruciate ligament(CL) injury(anterior CL in one and posterior CL in the other),and underwent bone-ligament-bone reconstruction.Medial collateral ligament reconstruction was performed using the semitendinosus tendon autograft ingrowth in the tibial tunnel.Results Primary healing was achieved in all the cases.In 10 of them,the stability of the knee was regained in 6-month follow-up;stress X-ray examination showed that the medial joint space was smaller than the contralateral one by less than 5 mm,and the position of the interference screw was optimal.Of the 12 patients,11 achieved an active knee flexion between 0? and 120?,the other,who had fracture of the lateral condyle of the femur,had a flexion of 90?.Conclusions Semitendinosus autograft provides sufficient tension for medial collateral ligament reconstruction.The fixation of the knee and the closure of the joint capsule can be achieved by using the method.

Pulmonary valve stenosis (PS) is a relatively common congenital heart disease,and there are 2 treatment methods of surgical operation and intervention.Percutaneous balloon pulmonary valvuloplasty (PBPV) was applied successfully in children with PS for the first time by Kan.For more than 30 years,with the update of intervention equipment,improvement of operation method and accumulation of clinical experience,the application of PBPV continuously has made new progress.Most of the previous reports of the PBPV were for the immediate and short-term efficacy,while long-term follow-up data and some special types of PS review research were less.Now,combined with PBPV clinical data and long-term follow-up study in recent years,an overview of the application progress of PBPV including indications,methods,curative effect and follow-up,prevention and cure of complications and some special type of PS are provided.

Cholangiocarcinoma (CCA) is a malignant neoplasm derived from cholangiocytes. The incidence of CCA is only lower than that of hepatocellular carcinoma and ranked the second in liver malignant cancers. The prognosis of CCA patients is poor and most patients will die within a few months after diagnosis. CCA is related to various risk factors, including primary sclerosing cholangitis, cirrhosis, certain chemical agents and liver fluke. Establishment of proper animal models of CCA can not only be helpful for understanding the mechanisms of incidence and development, but also lay a solid foundation for developing novel treatment strategies. Common animal models of CCA include carcinogen-induced models, implantation models, operation models, and genetically engineered models.

OBJECTIVE:To study the potential targets of Guizhi decoction regulating Ying and Wei based oncorrespondence between formulation and syndromerelationship and reverse molecular docking technology. METHODS:Active ingredients related to Guizhi decoction were obtained by literature retrievals,and PharmMapper Server was used for reverse molecular docking for ac-tive ingredients. The potential receptors of Guizhi decoction were found on the basis of docking scores,then AutoDock Vina was conducted for positive molecular docking test to observe the affinity between the ligand and the receptor molecule. 75 rats were ran-domly divided into normal group,model group,Guizhi decoction high-dose,medium-dose,low-dose groups(12,8,4 g/kg),15 in each group. Except for normal group,rats in other groups were induced for models with disharmony between Ying and Wei. Af-ter modeling,rats were intragastrically administrated once a day,for 5 d. After administration,11β-HSD1 expression levels in adi-pose tissue and muscle tissue of rats were detected. RESULTS:Reverse molecular docking for active ingredients of Guizhi decoc-tion found that 11β-HSD1 was the frequent receptor,and positive docking test confirmed that uralsaponin b,glycyrrhetnic acid and carbenoxolone and so on had higher affinity with 11β-HSD1. Results of animal test showed,compared with normal group,11β-HSD1 expression levels in adipose tissue and muscle tissue in model group were increased (P<0.05);and compared with model group,11β-HSD1 expression levels in adipose tissue and muscle tissue in Guizhi decoction high-dose group were decreased (P<0.05). CONCLUSIONS:Guizhi decoction regulating Ying and Wei has certain correlation with 11β-HSD1,while the reverse molec-ular docking technology can provide a feasible technical way to studycorrespondence between formulation and syndromerelation-ship.
