Objective To investigate the feasibility and clinical effects of suture anchors technique for acute distal avulsion fracture of patella. Methods From January 2007 to July 2009, 33 patients(18males and 15 females, ranging from 28 to 72 years, with an average of 49.3 years) were treated with the suture anchors technique. The average time from injury to surgery was 3.5 days(2 to 7 d). Injury reason: traffic accident in 12 cases, injured in daily life in 11 cases, sports injury 9 cases, no clear trauma history in one case. The Bostman evaluation system, follow-up X-ray, and knee mobility were used to analyze the clinical effects of suture anchors technique. Results All patients obtained the follow-up and the average time was 16.5 months(12 to 23 months ). One patient suffered foreign body reaction, and his wound healing was good after operation. The remaining patient wound healing was good. No complications were found in all patients,such as popliteal fossa artery, tibial nerves or peroneal nerve complication. Bostman patella fracture functional score 27.3±2.3 points at the sixth months follow up, 28 cases were rated as excellent, 5 cases were good, and the excellent and good rate was 100%. Six months later, X-ray showed bone healing, knee activity recovered well. The Range of Motion was extension for -2.5°±2.1° and flexion for 122°±5.3°. Conclusion Suture anchors fixation in treatment of acute distal avulsion fracture of patella has a good efficacy, safety and reliability advantages, and without the second operation. This technique provides an alternative in lower pole patella fracture.

Objective To evaluate the clinical efficacy of 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) in the treatment of condyloma acuminatum. Methods Thirty-six cases of condyloma acuminatum were treated with ALA-PDT. Results After the treatment, 33 (91.67%) patients were cured, 35 (97.22%) improved. Relapse occurred in 3 (8.33%) patients. Side effects were noted in 2 (5.56%) patients. Conclusions ALA-PDT is a relatively simple, effective and safe treatment with a lower recurrence rate for condyloma acuminatum, especially for small skin lesions or lesions at specific area. However, the high expense required for multiple treatments with ALA-PDT may restrict its application.

Objective To summarize the experience of surgical management of postoperative intrahepatic duct stones and strictures with choledochoscope.Methods The clinical data of 1241 patients with intrahepatic duct stones and strictures who were admitted to the Shenzhen People's Hospital from January 2000 to December 2011 were retrospectively analyzed.All patients were divided into postoperative choledochoscopy group (652 patients were treated by choledochoscope through T-tube fistula) and conservative treatment group (589 patients were treated by cholangic and antibiotic drugs) according to treatment plan.The clinical data including stricture alleviation,incidence of complications and treatment efficacies of the 2 groups were compared using the chi-square test.Results In the postoperative choledochoscopy group,the intrahepatic duct stones of 630 patients were completely removed,with the removal rate of 96.63% (630/652),which was significandy higher than 76.23% (449/589) of the conservative treatment group (x2=113.407,P < 0.05).A total of 1237 intrahepatic duct strictures were detected in the postoperative choledochoscopy group,including 698 cases of membranous stricture (the length of strictured bile duct < 2 mm),529 cases of spool-shaped stricture (2 mm ≤ the length of strictured bile duct ≤5 mm),8 cases of long tube-shaped stricture (the length of strictured bile duct > 5 mm),2 cases of crackshaped stricture.The alleviation rate of the stricture was 99.35% (1229/1237).The conditions of 6 cases of long tube-shaped stricture and 2 cases of crack-shaped stricture were not alleviated.There were 986 cases of intrahepatic duct strictures in the conservative treatment group,and the stricture alleviation rate was 80.43% (793/986).There was a significant difference in the stricture alleviation rate between the 2 groups (x2=238.994,P < 0.05).Nine patients in the postoperative choledochoscopy group had severe complications.Five patients had intrahepatic duct hemorrhage with a volume of blood loss more than 1500 ml,and they were treated by balloon dilatation hemostasis.One patient with repeated intrahepatic duct bleeding received hepatectomy.Two patients with severe intrahepatic cholangitis received choledochoscopy.Two patients had incomplete formation of sinus and they received implantation of biliary stents under duodenoscope.Conclusion Standard surgical management with choledochoscope can effectively alleviate postoperative intrahepatic duct stones and strictures.

The nutritional and food hygienic character of the new developed soy protein concentrate and soy protein isolate in Heilongjiang province were studied by chemical analysis and rat experiment. These products have not yet been reported in China. The results indicated that the content of protein of soy protein concentrate and isolate was 69.76 and 83.11%(as anhydr-ate basic), the PER 2.00 and 1.34, the apparent digestibility 77.54 and 85.72%, the true digestibility 84.33 and 93.19%, the biological value 79.80 and 62.54%, the NPU 67.39 and 58.28% respectively.The essential amino acid composition of the two samples was the same as the products prepared in the other countries. By the hematological and pathological examination in rats, the contents of serveral harmful substan- ces were allowable or not detected. The authors belived that the nutritional quality of the two soy protein products was nearly the same as those in other countries, and its food safety was satisfactory.

Objective To explore effects of ginsenosides Rg1 on the expression of poly(ADP-ribose) polymerase-1 (PARP-1) and tumor necrosis factor receptor (TNFR) 1 in cortex cells after focal cerebral ischemia in rats. Methods Ninety healthy rats were randomly divided into sham-operative group, focal cerebral ischemia group, ginsenoside Rg 1groups (low, medium and high concentrations) and drug control group. Rats were intraperitoneally injected saline 45 mg/kg, saline 45 mg/kg+ginsenosides Rg1 10, 20 and 40 mg/kg, nimodipine 1 mg/kg 5 d before surgery, respectively. Focal cerebral isch?emia model was made by middle cerebral artery occluding in rats. The neurological deficit score and TTC staining were used to verify the success of the rat model. The expressions of PARP-1 and TNFR1 were evaluated by immunohistochemical meth?od and Western blot technique. Results There were obvious symptoms of neurological deficit and large pale infarct area in focal cerebral ischemia group compared with those of sham-operative group. There were higher percentages of neurological deficit score and infarct area in ginsenosides Rg1 groups and positive control group than those of sham-operative group, but which were lower than those of ischemia group (P<0.05). There were no significant differences between ginsenosides Rg1 groups and positive control group. The positive cells of PARP-1 and TNFR1 were higher in ginsenosides Rg1 low-dose group than those of sham-operative group and positive control group, while ones of medium and high-dose Rg1 group were higher than those of sham-operative group, and were lower than those of ischemia group (P<0.05). Compared with sham-op?erative group, PARP-1 and TNFR1 expression strips were significantly enhanced in ischemia group. Expression strips were higher in ginsenosides Rg1 low-dose group than those of sham-operative group. Expression strips were higher in ginsen?osides Rg1 medium-dose group than those of sham-operative group, but which were lower than those of ischemia group, and ones of high-dose group were lower than ischemia group (P<0.05). Conclusion Ginsenoside Rg1 shows protective effects on focal ischemia injury, which may be related with down-regulation of the expression of PARP-1 and TNFR1.
