Objective To adjust the layout of secondary medicine shelves in hospital pharmacy for outpatient services and optimize the varieties of automated equipment to improve working process and promote human-machine cooperation.Methods This article discussed the adjustment of the layout of secondary medicine shelves in hospital pharmacy for outpatient services and the optimization of varieties of automated equipment for storing by analyzing actual problems in automated system and clinical drug uses and the requirements of the automated equipment for drug storage respectively to improve working process and to adapt to the operation of outpatient pharmacy automated system.Results Dispensing efficiency of outpatient pharmacy automated system was improved, patients′ waiting time was significantly shortened, and the workload of pharmacists was decreased.Conclusion Optimization of hospital pharmacy drug delivery system and its operation can obviously improve work efficiency, shorten patients′ waiting time and reduce dispensing error, thus ensuring the safety of medication.

AIM: To study the apoptotic role of wild-type p53 in induction of plaque instability in atherosclerotic rabbits. METHODS: Fifty-four New Zealand White rabbits underwent balloon-induced abdominal aortic wall injury and then were fed on a diet of 1% cholesterol. At the end of the eighth week, the rabbits were randomly divided into two groups: group A and group B. Recombinant adenovirus carrying p53 and ?-galactosidase (LacZ) genes were injected in group A and B, respectively. Two weeks later, 10 rabbits each in group A and B was killed and the remaining rabbits all underwent pharmacological triggering with injection of Chinese Russell's viper venom and histamine. RESULTS: Compared with group B, p53 gene over-expression in group A resulted in a marked increase in number of positive apoptotic cells (2.5%?0.8% vs 1.0%?0.3%, P

OBJECTIVE To investigate the antibiotical resistance and to understand the phenotype and genotype of metallo-?-lactamase in Chryseobacterium indologenes.METHODS The MIC to 25 C.!indologenes strains was detected by agar dilution method.Phenotype of metallo-?-lactamase was detected by three-disc synergy test and modified three dimension test.Polymerase chain reaction(PCR)amplification for both metallo?-lactamase and integrase gene was conducted for all isolates.Complete coding gene of metallo-?-lactamase and their DNA sequence analysis was conducted.Conjugation experiment was used to study the transmission of metallo-?-lactamase encoding gene.pIs Of ?-lactamase was measured by isoelectric focusing assay.RESULTS The antibiotical resistance of C.indologenes to imipenem and meropenem was 88.0%,respectively.However,gatifloxacin,levofloxacin and rifampin had better antimicrobiotial ability to C.indologenes compared with other antibiotics in MIC Nineteen strains were identified to produce metallo-?-lactamase using three-disc synergy test and modified three dimension test.Twenty strains were detected to have metallo-?-lactamase genotype by PCR amplification using IND-like common prime sets and four prime sets of complete coding gene.Among them,9 strains were detected to have blaIND-1 genotype and 10 strains to have blaIND-2 genotype,strain CI-25 was identified to have blaIND-like genotype.The mutation of base sequences and amino acid sequences in 5 strains were found simultaneously.Conjugation experiment showed that metallo-?-lactamase encoding gene couldn′t transfer.Nineteen strains had 1 or 2 bands on isoelectric focusing electrophoresis.Strain CI-5 was proved to have blaIND-1,but phenotype of metallo-?-lactamase was negative.CONCLUSIONS C.indologenes has high rate of metallo-?-lactamase producing,and thus it is difficult to treat.The major genotype of metallo-?-lactamase for C.indologenes is blaIND-1 and blaIND-2 in Hefei.The expression of blaIND could exist negative or low level occasionally.

ObjectiveTo evaluate the effectiveness of transcatheter Amplatzer device closure on patent ductus arteriosus(PDA),and to give some evidences for the clinical application.MethodsAll studies in the world regard to the controlled trials(CT) about transcatheter Amplatzer device closure and cardiac surgery on PDA were searched and made synthetic evaluation by means of Meta-analysis.RevMan 4.2.2 software was used for statistical analysis.Cases relative risk(RR)and its 95% confidence interval(CI)of procedure failure,the incidence of complication and residual shunt were calculated.ResultsTotally 5 studies including 349 cases were analyzed.Operation failure of Amplatzer device occlusion was higher than cardiac surgery [5 CT,349 cases,3.0% vs 0,RR=4.29,95%CI(0.77,23.95)](P=0.10).Incidence of complication of Amplatzer device occlusion was lower than cardiac surgery[5 CT,343 cases,3.1% vs 38.0%,RR=0.11,95%CI(0.05,0.23)](P

Objective To study the relationship between Nogo-B and transforming growth factor-β1 (TGF-β1)/Smad2 signaling pathway in mice models of hepatic fibrosis.Methods Twenty four healthy male ICR mice were divided into two groups,with 6 in the control group and 18 in the model group.Mice in the model group were further divided into three subgroups according to different time points:subgroups of 4,8 and 12 weeks,with 6 mice in each subgroup.Hepatic fibrosis of mice was induced by subcutaneous injection of carbon tetrachloride (CCl4).The histopathologic changes of the liver were observed by optical microscope using hematoxylin-eosin and Masson trichrome stainings of the liver tissues.Expressions of Nogo-B,Smad2 and TGF-β1 mRNA and proteins in liver were detected by reverse transcription-polymerase chain reaction (RT-PCR),Western blot and immunohistochemistry assays,respectively.Means among groups were compared by univariate analysis of variance.Results The hepatic fibrosis models were successfully induced by CCl4 injection.The expressions of two subtypes of Nogo-B,Nogo-B1 and Nogo-B2 mRNA in normal livers were 0.140±0.050 and 0.104±0.023,but both significantly increased in the livers of mice in the 12 week model subgroup (1.054±0.040 and 0.500±0.057,F=431.41 and 135.46,respectively; both P＜0.01).The Nogo-B protein was mainly expressed in nonparenchymal cells of the liver,and was hardly expressed in hepatocytes.Linear correlation analysis showed that the expressions of Nogo-B mRNA and proteins were positively correlated with Smad2 and TGF-β1 mRNA and proteins (all P＜0.01),which were considered to participate in the signaling pathway of hepatic fibrosis.Conclusion Nogo-B might play a role in the development and progression of hepatic fibrosis by participating in TGF-β1/Smad2 signaling pathway.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.
