OBJECTIVE:To discuss the significance of passing GSP authentication of mono-drugstores by joining in the drugstore chain.METHODS:The status quo of GSP authentication was surveyed so as to find the merits of the GSP authenti-cation-passed drug chain retailers and the drug chain wholesalers.RESULTS&CONCLUSION:The mode of achieving the passage of GSP authentication of the mono-drugstore by joining in the drug store chain is feasible and essential.

Objective: To build up rabbit models of hepatic cirrhosis in through common bile duct partial ligation (CBDPL). Methods: Male New Zealand rabbits were subjected to CBDPL to induce hepatic cirrhosis. The liver biopsies were performed during the surgery and after sacrifice to evaluate hepatic fibrosis. The serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), total protein (TP) and albumin (ALB) were determined at week 0, 1, 2, 4 and 11 following the occlusion. Results: There were two kinds of morphological and histological manifestations after CBDPL, the one was inconspicuous hepatic fibrosis coexisted with sacculation-like bile ductal dilation and muddy stone; the other is remarkable hepatic fibrosis and cirrhosis along with uneven bile ductal dilation. The serum levels of ALT, AST, TBIL and DBIL were significantly higher after one week of operation. The levels of ALT, AST, TP and ALB decreased after two-week of operation, and the levels of TBIL and DBIL were returned to the normal level after two-week of operation. Conclusion: The animal models of hepatic cirrhosis can be built up through CBDPL in rabbits.

Objective:To investigate effects of hydrogen sulfide (H2S) on inducible nitric oxide synthase (iNOS) in kidneys of Type 1 diabetic rats.Methods:Thirty-two male SD rats were randomly divided into four groups:A normal control (NC) group,a diabetes mellitus (DM) group,a NaHS (NaHS+DM) group,and a NaHS control (NaHS) group (n=8 per group).Type 1 diabetes was induced by a single intraperitoneal injection of streptozotocin (55 mg/kg).After successful establishment of models,the rats in NaHS+DM and NaHS groups were injected with NaHS solution (56 μmol/kg) intraperitoneally.Eight weeks later,the activities of total nitric oxide synthase (T-NOS) and iNOS,as well as the level of nitric oxide (NO) were detected in serum and renal tissues,respectively,The activity of glutathione peroxidase (GSH-Px) was determined in renal tissues,The ultrastructures of renal tissues were observed by transmission electron microscope,The protein expression ofiNOS in renal tissues was detected by Western blot.Results:Compared with the NC group,there was no significant difference in the various indexes in the NaHS group (P＞0.05).However,in the DM group,the activities of T-NOS and iNOS,and the level of NO were all increased significantly in serum and renal tissues,while the activity of GSH-Px was decreased in renal tissues.Under the electronic microscope,the thickening of the glomerular capillary basement membrane,the proliferation of mesangial matrix,and the foot fusion were observed.The protein expression ofiNOS was increased obviously in renal tissues in the DM group (P＜0.01).Compared with the DM group,the activities of T-NOS and iNOS and the level of NO were all decreased in serum and renal tissues,while the activity of GSH-Px was increased in renal tissues in the NaHS+DM group (P＜0.01).The renal ultrastructural damages were ameliorated obviously.The protein expression ofiNOS was decreased significantly (P＜0.01).Conclusion:H2S exerts a protective effect on kidney injury in type 1 diabetic rats.The mechanism might be related to inhibition of iNOS activity and protein expression,in turn leading to reduction of NO content in renal tissues.

Objective To investigate the impact of early enteral nutrition on the nutritional status and complications of patients with advanced esophageal carcinomas.Methods Sixty-five patients with advanced esophageal carcinomas were randomly divided into the enteral nutrition group group (n =33) and the control group (n =32).The two groups were given enteral nutrition support and normal nasogastric feeding diet respectively in 24-72 h after hospitalization.The two groups were tested with nutrition indicators:body Mass Index (BMI)/brachial triceps skinfold thickness/upper arm circumference measurement,fasting blood glucose/serum total protein/albumin/cholesterol/triglyceride and the liver function (alanine aminotransferase (ALT)/aspartate aminotransferase(AST)/total bilirubin (TBiL)),and were observed the incidences of complications with liver/intestinal and infection diseases.Results After one month's treatment,compared with the control group,there was significant statistical difference between the two group in patients' nutritional status (BMI index:(22.1 ±4.5) kg/m2 vs.(19.2±4.3) kg/m2; skinfold thickness:(6.2 ±0.4) mm vs.(5.1 ±0.4)mm ; upper arm circumference:(22.8 ± 3.0) cm vs.(20.4 ± 3.2) cm ; serum total protein:(49.2 ± 10.1) g/L vs.(45.1 ± 9.9) g/L; Albumin:(35.5 ± 5.8) g/L vs.(30.6 ± 6.1) g/L; Cholesterol:(5.0 ± 0.6) mmol/L)vs.(4.3 ± 0.7) mmol/L)),the liver function(ALT:(36.0 ± 4.7) U/L vs.(61.5 ± 9.9) U/L; AST:(29.6 ±6.7) U/Lvs.(88.9±10.6) U/L;TBiL:(17.7±3.8) μmol/Lvs.(31.6 ±9.4) μmol/L) (t=2.624,2.036,2.220,2.256,4.155,2.207,2.349,2.476,2.280 respectively,P ＜ 0.05 for all),and the incidence of diarrhea (12％ (4/33) vs.34％ (11/32)) and infection (15％ (5/33) vs.41％ (13/32)) (x2 =2.501,2.193 respectively;P ＜0.05).No statistical difference was observed between the two groups on the levels of serum glucose and triglycerides,and the incidences of complications like bloating/constipation/reflux (P ＞ 0.05).Conclusion The early enteral nutrition could improve the nutritional status of patients with advanced esophageal carcinomas effectively,and reduce the incidence of liver injury,diarrhea and infection.
