Objective To investigate the effect of Suanzaoren Decoction on hippocampus, cortex BDNF and TrKB gene expression in depression model rats. Methods Depression rat models were established by social-isolated raise and chronic stress stimulation. Suanzaoren decoction was administrated to the models. RT-PCR was adopted to detect the expression of mRNA BDNF and TrKB genes. Results The mRNA expression of BDNF and TrKB in cortex of Suanzaoren decoction high dose group、medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580±0.012, 1.860±0.019)were all higher than the model group(0.032±0.008, 0.001±0.000), showing a significant difference among four groups (P<0.01), and the mRNA expression of BDNF and TrKB in hippocampus of Suanzaoren decoction high dose group, medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580± 0.012, 1.860±0.019)were higher than the model group (0.021±0.015, 0.125±0.013), there was a significant difference between four groups(P<0.01). Compared with the model group, the mRNA expression of low-dose group of Suanzaoren decoction in both cortex and hippocampus of BDNF and TrKB was not significantly different to the model group(P>0.05). Conclusion Suanzaoren decoction can increase the expression of BDNF and TrKB gene, promote neuronal proliferation, and resist depression.

Objective To investigate the effects of recombinant human growth hormone (rhGH) on tumor growth and vascular endothelial growth factor (VEGF) expression of human gastric carcinoma xenografts in nude mice with different expressions of growth hormone receptor (GHR). Methods Immunocytochemical method was used to pick out one GHR-positive and one GHR-negative cell line. Then the cells were subcutaneously injected into 24 nude mice separately. The nude mice bearing two different kinds of human gastric caicinoma were equalges of body weight and tumor volume of nude mice were recorded. Serum concentrations of VEGF in peripheral blood were analyzed by ELISA. VEGF protein and mRNA expression in tumor tissue were detected by immunohistochemistry and RT-PCR, respectively. Results We chose SGC-7901 as GHR positive group, and MKN-45 as the negative one. For nude mice bearing GHR + SGC-7901 xenografts, the tumor volumes were significantly larger in rhGH groups than in control group (P < 0.05), and the high-dose rhGH group revealed greater effect (P < 0. 05).Body weights were not significantly different among three groups (P > 0. 05). Serum VEGF concentration was (252.94 ± 15.32) ng/L in the high-dose rhGH group, which was significantly higher than that in control group [(49.94 ± 5.73) ng/L] and low-dose rhGH group [(167.60 ± 9.54) ng/L] (P < 0.05). Moderate positive staining with VEGF was observed in the control group, while VEGF staining was strong in rhGH administration groups. The relative expression of VEGF mRNA for the high-dose rhGH group was 0. 6470 ± 0. 0447, which was significantly higher than that in control group (0. 3230 ± 0. 0258)and low-dose rhGH group (0. 412 ± 0. 0351)(P < 0.05). While for nude mice bearing GHR-MKN-45 xenografts, the body weights of the rhGH-administrated groups were significantly higher than that of control group (P < 0.05), while tumor growth, serum VEGF concentration, and the expressions of VEGF mRNA and protein in tumor tissue were not significantly different (P > 0.05).Conclusions rhGH can promote tumor growth and increase the expression of VEGF in the GHR-highly-expressed SGC-7901 xenograft tumor model. However, such effects do not exist in GHR-negatively-expressed MKN-45 xenograft tumor model. The existence of GHR may be a key target where rhGH influences the secretion of VEGF.

Human enterovirus 71 (EV71) is one of the major etiological agents for the hand, foot, and month disease (HFMD) and is causing frequent, widespread occurrence in the mainland of China. The single positive-stranded RNA genome of EV71 is translated into a single polyprotein which is autocleavaged into structural and nonstructural proteins. The functions of many nonstructural proteins characterized in the life cycle of virus are potential targets for blocking viral replication. This article reviews the studies of the structures and functions of nonstructural proteins of EV71 and the anti-enterovirus 71 drugs targeting on these nonstructural proteins.

Objective To investigate the effect of norcantharidin on growth inhibition and induction of apoptosis of human rectal cancer Colo 320 cells. Methods Norcantharidin (NCTD) in different concentrations were added to rectal cancer Colo 320 cells. Morphological characteristics of apoptosis were observed using the light microscope and transmission electron microscope. The expressions of Bag-1 and Bcl-2 proteins were tested by Western blotting. The growth inhibition of Colo 320 cells on the cell cycle was observed by flow cytometry. Results The apoptosis morphological changes of Colo 320 cells were observed by the light microscope and transmission electron microscopy. Flow cytometry analysis showed that the cell count of G2/M phase in experimental group was higher than that in control group ( <0.05) but the cell counts of G0/G1 and S phases have decreased in experimental group after treatment with NCTD at the concentrations of 5μg/mL, 10μg/mL and 20 μg/mL, and presented dosage dependence relations. The expressions of Bag-1 and Bcl-2 proteins have decreased. Conclusion Norcantharidin has inhibitory effect on rectal cancer Colo 320 cells, and the effect may be related to the cell cycle arrest and apoptosis.

OBJECTIVE:To provide reference for the development and improvement of pharmaceutical care in our hospital. METHODS:By questionnaire investigation,habits and understarding situation and demand of knowledge of drug use among pa-tients in our hospital were randomly collected by face-to-face interview or network platform. A statistical analysis was carried out on obtained results. RESULTS:In this questionnaire investigation,289 questionnaires were sent out face-to-face,and 282 valid ques-tionnaires were returned with effective feedback rate of 97.58%. Totally 51 valid questionnaires were returned through network plat-form. A total of 333 valid questionnaires were returned through two ways. The results of questionnaire investigation showed that 44.14% of the surveyed patients would read the drug instructions before taking drugs;41.14% of the surveyed patients would pay more attention to ADR and cautions stated in drug instructions. More than 60% of the surveyed patients had various bad habits of drug use. When getting better,66.07% of the surveyed patients would stop using drugs or reduce the dosage. When having not im-proved,26.73% of them would change drugs or increase dosage.Consulting with the medical staff was the most common source(69.07%)of drug use knowledge,and it was also the most trusted source(84.08%). Among the knowledge of drug use, surveyed patients most expected to understand theADR and side effects(65.46%),and the selectionindication and main us-er,cautions,drug interaction in multiple useandusage and dosagewere also selected frequently,and the choices of some options were significantly affected by the characteristics of people,such as age and education degree(P<0.05). The most expected way to acquire drug use knowledge wasface-to-face consultation with medical staff (72.97%),followed bytelephone consulta-tionandnetwork consultation,and the choices of some options were significantly affected by the characteristics of people,such as age and education (P<0.05). CONCLUSIONS:Patients in our hospital haven't pay enough attention to drug instructions and their content,and bad habits of drug use still exist. Sources of drug use knowledge are diverse,but confidence of other sources is not enough except for source of medical staff. The demands for the knowledge of drug use are different,however,the present form and content of pharmaceutical care in our hospital cannot fully meet the needs of patients.
