Objective To discuss the clinical effect of combination therapy under the theory of "treating soft tissue for bone disease" on knee osteoarthritis.Methods The 160 cases were randomly divided into control group(80 cases) and experimental group(80 cases).The control group was treated by diclofenac sodium sustained release capsules(per os) and sodium hyaluronate(intra-joint injection).The experimental group was treated by traction,steaming and washing,massage,needle-knife therapy,manipulation on soft tissues for loosening the joint,and orthepedic insoles.The course of treatment was 3 weeks.The effect was evaluated according to Lysholm Score,knee movement and subjective satisfaction after the follow-up for 6 months.Results Of the 154 cases completed the study(control group 75 cases and experimental group 79 cases),the Lysholm Score and knee movement had a very significant improvement(P

Objective To evaluate upfront common bile duct suturing against T-tube drainage after exploration in the treatment of common bile duct stone.Methods 253 cases of extrahepatic bile duct stones treated at our department from 2008 June to 2012 January were randomly divided into primary suture group and T tube drainage group,by t test or analysis of variance independent sample comparison.Results All operations were successful.Postoperative bile leakage was observed in 2 patients in group A and 4 in group B respectively(P ＞ 0.05),there was no reoperations in the two groups.In group B retrograde biliary tract infection developed in one and was cured by biliary tract flush combined with antibiotics administration.The abdominal drainage was bile tainted fluid about 5-10 ml a day in bile leakage cases in both groups and healed itself in 3-4 days without fever,jaundice symptoms.There was no other severe complications such as pancreatitis.The postoperative biliary complication rate (P =0.802),operative time (P =0.137),intraoperative blood loss (P =0.069) and liver function recovery(ALT P =0.087,AST P =0.752,TBIL P =0.459,DBIL P =0.217,ALP P =0.576,GGT P =0.362) was not significantly different between the two groups.In group A postoperative flatus passing (P =0.037),postoperative fluid volume (P =0.008),postoperative hospital stay(P =0.015) were better than that in T-tube drainage group.At 3 to 12 months follow-up,no patients were found to have residual stones and biliary stricture in group A and group B.Conclusions With the definite indication and proficient surgical technology,primary suture of common bile duct after exploration is a safe and effective way after treatment of choledocholithiasis.

A new-designed axial flow blood pump, dived by magnetic coupling and using internal hollow brushless DC motor and inlet and outlet in line with impeller, was tested in mimic circuit. The results showed good performance of the new pump and indicated that its hydrodynamic characteristic can meet the demands of clinical extracorporeal circulation and auxiliary circulation.
