Objective:To describe antipsychotic medication prescription patterns and estimate the associated costs for patients with schizophrenia in Tianjin,China. Methods:Data were 30%random sampling from the Tianjin Urban Employee Basic Medical Insurance (UEBMI)database. Adult patients with≥ 1 diagnosis of schizophrenia, antipsychotics prescribed at the first diagnosis of schizophrenia (index date),and 12-month continuous enrollment after the first antipsychotic prescription (follow-up period)between 2008 and 2010 were included. The classes and number of antipsychotics patients prescribed at index date and patterns of antipsychotics patients maintained/changed during the study period were described. The total direct medical costs were also estimated. Results:Among 2125 patients with schizophrenia,1739 (81. 8%)prescribed with antipsychotic medication prescriptions were in-cluded. At the index date,1461 (84. 0%)of the patients prescribed with one antipsychotic medication,278 (16. 0%)with more than two antipsychotics,and 747 (43. 0%)were prescribed with first-generation antipsychot-ics,813 (46. 8%)with second-generation antipsychotics and 179 (10. 2%)with both. During the following 12 months,1387 (79. 8%)patients remained on the index antipsychotic class. The total cost for 1739 patients was (12498. 9 ±14575. 2)CNY. The total direct medical cost was significantly lower for patients only prescribed with second-generation antipsychotics compared with ones only with first-generation antipsychotics [(9064. 1 ±13209. 8) CNY vs. (1 1928. 6 ±13767. 4)CNY,P<0. 001 ]. In addition,the cost for patients prescribed with first-generation and second-generation antipsychotics was 18821. 8 ±15702. 7 CNY. Conclusion:Majority of patients are prescribed with monotherapy,and tend to stay with one antipsychotic medication class. The total medical cost for patients with second-generation antipsychotic medications is lower than first-generation ones.

This paper reported 65 cases of hepatectomy on patients with intrahepatic cholelithiasis, among which 62 were left lateral lobectomy, 2 left hemihepatectomy and 1, right hemihepatectomy. The incidence of postoperative complication was 21.5%: incision infection (8 cases), subphrenic abscess (3 cases), biliary fistula (1 case), and septicemia and duodenal fistula which caused the death of the patients (one each). The complications are related to the number of previous operations, the biliary infection and the improper drainage. Attention should be paid to the following aspects to prevent complications: (1) strict observation of indications for hepatectomy; (2) correct management of the raw surface; (3) adequate maintenance of bile drainage; (4) proper choice of drains.

Objective:To study the effects of somatostatin on portal pressure and operative complications in patients of portal hypertension treated with porta-azygous disconnection. Methods:Twenty patients with portal hypertension were treated with azygoportal disconnection. The severity of liver disease according to the Child-Pugh's grade was B in all patients. The patients were divided into two groups. The patients in group A were treated with intravenous infusion of somatostatin (6 mg/24 h) one day before operation and five days after operation. The patients in group B were treated with azygoportal disconnection without the use of somatostatin. The portal pressure, the volume of bleeding during operation, and the ascites and complications after operation were evaluated. The serum concentration of GLU, NO and ET-1 were determined. Results:The portal pressure and GLU concentration in patients of group A were lower than those in patients of group B. There were no differences of NO, ET-1 in patients between group A and group B. The volume of bleeding, ascites and complications in patients of group B were higher than in patients of group A. Conclusion:The use of somatostatin before and after porta-azygous disconnection can decrease portal pressure. It is beneficial in reducing the volume of bleeding in operation, ascites and complications after operation.
