To analyze the prescription and medication regularities of traditional Chinese medicines in the treatment of melancholia in the Chinese journal full text database (CNKI), Wanfang Data knowledge service platform, VIP, Chinese biomedical literature database (CBM) in based on the traditional Chinese medicine inheritance support platform software, in order to provide reference for further mining traditional Chinese medicines for the treatment of melancholia and new drug development. The traditional Chinese medicine inheritance support platform software V2.0 was used to establish the prescription database of traditional Chinese medicines for treating melancholia. The software integrated data mining method was adopted to analyze four Qis, five flavors, meridian distribution, frequency statistics, syndrome distribution, composition regularity and new prescriptions. Totally 358 prescriptions for treating melancholia were analyzed to determine the frequency of prescription drugs, commonly used drug pairs and combinations and develop 22 new prescriptions. According to this study, prescriptions for treating depression collected in modern literature databases mainly have the effects in soothing liver and resolving melancholia, strengthening spleen and eliminating phlegm, activating and replenishing blood, regulating liver qi, tonifying spleen qi, clearing heat and purging heat, soothing the mind, nourishing yin and tonifying kidney, with neutral drug property and sweet or bitter flavor, and follow the melancholia treatment principle of "regulating qi and opening the mind, regulating qi and empathy".

Objective To investigate the changes in metabolic indexes and anesthesia administration during perioperation in patients undergoing orthotopic liver transplantation. Methods Eleven patients who underwent orthotopic liver transplantation were selected. Their pH, BE, HCO 3 -, K +, Ca 2+, blood glucose, PT, APTT and FIB were assessed at 60 min of pretransplantation, 20 min and 40 min of liver transplantation, 20 min and 40 min of new liver reperfusion. Results The pH, BE, HCO 3 -, K +, Ca 2+ during 20 min and 40 min of liver transplantation decreased more significantly than those during pretransplantation 60 min, PT and APTT extended markedly, the level of blood glucose did not change markedly; pH, BE, HCO 3-, K +, Ca 2+ and the level of blood glucose during new liver reperfusion 20 min and 40 min increased significantly compared to those during liver transplantation 20 min and 40 min; PT, APTT and FIB did not change markedly. Conclusion Metabolic indexes during liver transplantation change more markedly than those during pretransplantation or new liver reperfusion.

Objective: To study the effects of vitamin E and selenium on apoptosis and c-Myc expression in human leukemia cells. Methods: DNA gel electrophoresis and Northern blotting hybridization were used to detect the apoptosis and the expression of c-Myc gene, respectively. Human leukemia cell line HL-60 and K562 were cultured in vitro. Results: The apoptosis of HL-60 and K562 cells were induced after being exposed to vitamin E (100 ?mol/L) and selenium (8 ?mol/L) for 24 hours, respectively. In HL-60 cell line, c-Myc mRNA was down-regulated significantly by vitamin E(100 ?mol/L),but not selenium(8 ?mol/L).In contrast, the expression of c-Myc gene was repressed by selenium(8 ?mol/L) and not by vitamin E(100 ?mol/L) in K562 cell. Conclusion: Our observations suggest that c-Myc down-regulation and induction of apoptosis by selenium and vitamin E are important pathways in repressing leukemia cell proliferation.The results suggest there are different mechanisms of repressing leukemia cell proliferation for selenium and vitamin E.

Hepatitis B virus(HBV) infection is a severe health problem in the world.However,there is still not a satisfactory therapeutic strategy for the HBV infection.To search for new anti-HBV agents with higher efficacy and less side-effects,the inhibitory activities of traditional Chinese medicine Rheum palmatum L.ethanol extract(RPE) against HBV replication were investigated in this study.Quantitative real-time polymerase chain reaction(PCR) was employed to analyze the inhibitory activity of RPE against HBV-DNA replication in a stable HBV-producing cell line HepAD38; the expression levels of HBV surface antigen(HBsAg) and e antigen(HBeAg) were also determined by enzyme linked immunosorbent assay(ELISA) after RPE treatment.RPE could dose-dependently inhibit the production of HBV-DNA and HBsAg.The concentration of 50% inhibition(IC50) was calculated at 209.63,252.53 μg/mL,respectively.However,its inhibitory activity against HBeAg expression was slight even at high concentrations.RPE had a weak cytotoxic effect on HepAD38 cells(CC50 = 1 640 μg/mL) and the selectivity index(SI) was calculated at 7.82.Compared with two anthraquinone derivatives emodin and rhein,RPE showed higher ability of anti-HBV and weaker cytotoxicity.So Rheum palmatum L.might possess other functional agents which could effectively inhibit HBV-DNA replication and HBsAg expression.Further purification of the active agents,identification and modification of their structures to improve the efficacy and decrease the cytotoxicity are required.

Sucking mice, 2～3 day after birth, were intraperiton eally inoculated with 0.05mL F1M10 of Chen Strain Hantaan virus. At diff erent t ime point after inoculation, the brains were taken, routinely fixed and embedded in paraffin for preparing 5 μm serial sections. Traditional and confocal immun ochemical detection of viral antigens and heat shock protein 70 were performed t o exp lore the cerebral stress response after viral infection. The results showed that HSP70 immunoreactivities could be stably detected in the viral antigen positive neurons, but not in the viral antigen negative or uninfected control tissues. B y confocal microscopic examination, the HSP70 and viral antigens were colocolize d in the neuronal cytoplasm. Our result, comparable to our previous findings in human tissues and culture cells, indicated that Hantavirus infection can induce the expression of HSP70 in the infected cells, and HSP70 expression might be n ecessary but not sufficient to keep the cell survival.

Background Researches showed that the content of nitric oxide (NO) and nitric oxide synthetase (NOS) increases in blood,aqueous humor and tear of cataract patient.But the function of NO and NOS in cataract formation is still elusive.Objective The aim of this study was to explore the prevention and treatment effect of NOS inhibitor,1-nitro-arginine methyl ester (L-NAME),on galactose cataract.Methods Sixty clean three-week-old Wistar rats were equally and randomly divided into 3 groups.0.9％ Normal saline solution (30 ml/kg) was subcutaneously injected every day for 30 days in the rats of the control group,and 50％ of D-galactose solution (30 ml/kg) was used in the rats of the model and L-NAME group at the same way.L-NAME eye drops was simultaneously administered in the L-NAME group 3 times per day for 30 days.The eyes of the rats were examined under the slit lamp in 10,20 and 30 days,and the degree of lens opacification was scored.Lenses of the rats were obtained at the end of this experiment for the detect of NO,NOS contents.Flow cytometry was used to assay the caspase-3 level of rat lens.Repeated measurement two factor analysis of variance was used to analyze the difference of lens opacification scores in different groups and different time points,and one-way ANOVA was used to analyze the differences of NO,NOS and caspase-3 contents in lens among the groups.Results Lens opacification appeared in 10 days after injection of 50％ D-galactose solution in the rats of the model group and L-NAME group.Lens opacification score was higher among the different groups and different time points (Ftime =435.251,P =0.000 ;Fgroup =395.120,P=0.000).NO content in the lens was (0.45±0.15) μmol/g,(2.67 ± 0.47) μmol/g and (1.68±0.34) μmol/g in the control group,model group and L-NAME group,showing a significant difference (F=58.872,P=0.000).The NOS contents in the lens was (0.0160±0.0020) U/ml,(0.0370±0.0040) U/ml and (0.0270±0.0010) U/ml in the control group,model group and L-NAME group,showing a significant difference (F =66.174,P=0.000).Caspase-3 contents in the lens was (339.4 ± 37.9),(697.7 ± 46.5) and (650.7 ± 53.1),Showing a significant difference among them (F =100.005,P =0.000).Conclusions The increase of NO,NOS and caspase3 levels are associated with lens opacification.Topical administration of L-NAME eye drops can down-regulate NOS content in lens,reduce the NO formation and inhibit the apoptosis of lens epithelial cells.
