METHODS: Kromasil C18 column(250 mm?4.6 mm,5 ?m)was used as chromatographic column,and the mobile phrase consisted of methanol-0.2% phosphoric acid(80∶20) at a flow rate of 1.0 mL?min-1 and the det-ection wavelength was set at 208 nm,and the column temperature was maintained at room temperature.RESULTS:The calibration curve of Oleanolic acid was in good linearity over the range of 0.237～4.740 ?g(r=0.999 8).The average recovery of Oleanolic acid was 98.84% with RSD at 1.19%(n=6).CONCLUSION:The method is simple,feasible and reproducible, and can be used for the quality control of Ziyin shugan granule.

Schistosomiasis hematobia is one major human schistosomiasis. The disease is endemic in Africa and Mediterra-nean region,and is the main cause of urogenital diseases. Although only Schistosoma japonicum is spreading across the Main-land China,now more schistosomiasis hematobia cases are reported among aid projects and migrant workers to Africa,with the economy development and the increasing degree of foreign exchanges. Meanwhile,the relevant clinical data of schistosomiasis hematobia are rare in China. This article reviews the clinical manifestations and progress in diagnosis and treatment of the dis-ease.

Objective To investigate the protective effect of prostaglandin E1 (PGE1) on platelet during cardiopulmonary bypass (CPB).Methods A total of 24 patients undergoing cardiac valve replacement were randomly divided into the experimental group (n=12) and the control group (n=12).The levels of thromboxane B2 (TXB2) and 6-keto-prostaglandin F1?(6-K-PGF1?) in serum were measured at different intervals during and after CPB. The ultrastructure of platelets was also observed by transmission electron microscope.Results The levels of TXB2 and 6-K-PGF1? during CPB were significantly higher than those before CPB in the both groups(P

Objective To compare the therapeutic effect of anatomic plate (AP)and locking compression plate(LCP) in treatment of fermoral intertrochanteric fracture in elderly patients. Methods Nineteen and three patients with fermoral intertrochanteric fracture were treated with anatomic plate (AP) and locking compression plate (LCP). The therapeutic effects were compared in the study. Results All operations were done successfully. Of all cases,72 patients were followed up for 5-24 months. Excellence rate: AP was 66. 7% and LCP was 88. 2%.Conclusions AP had significantly low excellence rate with more complications when compared with LCP. LCP could be the first choice in treatment of fermoral intertrochanteric fractures with high excellence rates and few complications.

Objective To evaluate the management of biliary complications (BC) following orthotopic liver transplantation (OLT). Methods From Feb 1999 to Feb 2004, 236 cases underwent OLT with end-to-end choledocho-choledochostomy. Biliary anastomosis was performed by intermittent suture with T tube placement in 96 cases, without T tube in 39 cases, by continuous suture in posterior wall and intermittent suture in anterior wall and without T tube in 101 cases. Results Thirty-two (13.3%) patients developed BC, with incidences in group 1, 2 and 3 of 17.7%, 15.4% and 7.9%, respectively. The incidence of hepatic hilar and/or intrahepatic bile duct strictures was 8.3%, 2.6% and 1.0%, respectively. BC incidence in group 3 significantly decreased. Twenty patients with biliary stricture underwent endoscopic and/or radiological interventions, and stricture resolution was achieved in 90% of patients with anastomotic strictures and 60% of patients with hepatic hilar and/or intrahepatic strictures. Conclusions Modified biliary tract reconstruction technique contributes to the decrease of BC. Endoscopic and/or radiological interventions should be used for non-ischemic anastomotic biliary strictures or simple hepatic hilar strictures.

Objective To report effects of microsurgical treatment for tumors in cervical spinal canal. Methods A total of 32 cases of tumors in cervical spinal canal had received microneurosurgery through a posternmedial approach. 22 cases had received reconstruction of cervical spinal canal stability. Results A total tumor resection was performed in 26 cases (81.25%),a subtotal tumor resection was conducted in 6 cases(18.75%). A cemplete recovery was achieved in 23 cases(71.88%), an improvement of symptoms was achieved in 6 cases(18.75%), and no improvement in 3 cases(9.38%), no death was encountered. Follow up observations were carded out in 30 cases for 3 months to 3 years. MRI examinatious 3 months after operation in 26 cases found no residual or recurrent tumor,recurrence was seen in 3cases of astrocytoma, 1 case was invariable. X-ray radiography in 26 cases showed good vertebral stability ,spinal deformation was found in 4 eases. Conclusion Microsurgery in early period play a key role in treatment of cervical spinal tumors. Reconstruction of spinal canal stability is important to patients.

Objective To assess the preventive effect of artesunate against reinfection of Schistosoma japonicum.Methods Volunteers were divided into 3 groups,Medication Group Ⅰ took artesunate 6 mg/kg ,once a week for 4 weeks,Medication Group Ⅱ took artesunate 6 mg/kg in the 1st and 3rd week,twice a week,and a control group was given a placebo.The 3 teams took praziquantel 40 mg/kg on the 4th weekend.The effects of artesunate in early treatment were observed at the 8th weekend,and the preventive effects of artesunate against reinfection were assessed at the 12th weekend.The positive rate of fecal examination was used as the indicator.Results In the stage of early treatment,the positive rates of fecal examination in Medication Group Ⅰ ,Ⅱdecreased significantly compared with the data before the study with all P values less than 0.05 ;in the stage of preventing reinfection,compared with the data before the study,the positive rates of the fecal examination declined significantly in Medication Group Ⅰ,Ⅱ ,with all P values less than 0.05.While in the control group,the positive rates of the fecal examination had no significant changes in the two stages.Conclusions Artesunate has a valid effect against schistosome infections in the early treatment and can prevent residents from reinfection,and the suitable dosage is 6 mg/kg,once a week for 4 weeks.
