Objective:To study the anti-fibrogenetic effect of matrine compound injection and its mechanism. Methods: Experimental liver fibrosis induced by tetrachloride in rats was treated by matrine compound injection. Liver function index, interleukin-1? (IL-1?) and pathological changes in liver tissue were observed in model and therapy groups during the 4th,6th and 9th week. Results:The serum IL-1? levels of model and therapy groups were (25. 51?14. 31) and (10. 49?7. 49) pg/ml in the 4th week, (109. 67?20. 87) and (15. 06?2. 65) pg/ml in the 6th week, and (40. 26?10. 63) and (23. 27?7. 56) pg/ml in the 9th week. The liver function (ALT, AST, TBil) of therapy group was better than that of model group at each stage. Pathological changes indicated that the infiltration of inflammatory cells,the degree of liver cell necrosis and the degree of fi-broplastic proliferation in the therapy group were obviously better than those of the model group. Conclusion : Matrine compound injection has an anti-fibrogenetic action on the liver fibrosis induced by tetrachloride.

With its abilities of trans-synaptic tracing and self-replication and wide host range, pseudorabies virus (PRV) has been applied in the field of neuroanatomy since the 1970s. Four decades of PRV application have made many advances in researches on neuronal tracing with PRV. Mechanism studies focused on investigating infection of primary neurons and tracing direction in secondary neurons, while application studies focused on development of new pathological strains and innovation of tracing techniques. To date, the mechanism and application of viral tracing are not completely figured out yet. Integration of molecular biology technology will improve the efficiency in related researches.

The postpartum depression outcome and the effect of psychological intervention were studied in order to reduce the occurrence and development of the postpartum depression. A survey of 4000 women within 4-6 weeks postpartum in 80 communities in Shenzhen, China was performed using random cluster sampling method. By employing Edinburgh Postnatal Depression Scale (EPDS) as a screening tool, the positive women (defined as EPDS ≥10) were randomly divided into intervention group and control group at a ratio of 1:2. The women in the intervention group were treated by means of mailing postpartum depression prevention and treatment knowledge manual, face-to-face counseling, and telephone psychological counseling interventions aiming at individual risk factors, while those in the control group were treated with conventional methods. EPDS scores were assessed in these two groups again at 6th month postpartum. Totally, 3907 valid questionnaires were obtained. All the 771 positive women were divided into two groups: 257 in the intervention group, and 514 in the control group. At 6th month postpartum, the EPDS scores in the intervention group were decreased significantly, from baseline stage (12.84±3.02) to end stage (3.05±2.93), while EPDS scores in the control group were reduced from 12.44±2.78 to 6.94±4.02. There were significant differences in the EPDS scores at end stage between the two groups (t=13.059, P<0.001). Psychological intervention can reduce postpartum depression, with better maternal compliance. It is feasible and necessary to establish postpartum depression screening and psychological intervention model in community-hospital and include the postpartum depression screening, intervention, and follow-up into the conventional healthcare.

A transmissible gastroenteritis virus strain was isolated from suspect samples in Sichuan province and identified by ST cell culture, direct fluorescent antibody test (FA), neutralization test (NT), TME examination and some other methods, then it was named SC-Y. The isolated strain could produce obvious cytopathic effects (CPE), The TCID50 was 10(-3.664)/0.05 mL, The neutralization index is 52.5. cDNA fragments covering the complete genome were amplified by the long reverse transcription PCR. The amplified fragments were further cloned and sequenced. The genome of SC-Y strain was assembled by BioEdit. The length of complete genome was 28590 nucletides, and was composed of 7 ORFs, which was flanked by untranslated regions (UTRs) with 315 bases at the 5'-end and 277 bases at the 3'-end. Phylogenetic analysis based on genome suggested that SC-Y might belong to same subgroup with Purdue strain.

OBJECTIVE:To study the relative bioavailability,pharmacokinetics and bioequivalence of domestic nisoldipine tablets in healthy volunteers.METHODS:A single oral dose of 10 mg test and reference nisoldipine tablets were given to 24 male healthy volunteers in an open randomized 2?2 latin square design.The plasma concentrations of nisoldipine at different time points were determined by LC-MS and the pharmacokinetic parameters of the two kinds of tablets were computed and their bioequiavailability was evaluated.RESULTS:The main pharmacokinetic parameters of the test vs.reference formulations of nisoldipine in 24 healthy volunteers were as follows:Cmax(2.94?2.78)ng?mL-1 vs.(3.22?2.16)ng?mL-1,tmax(1.70?1.00)h vs.(1.40?1.00)h,t1/2(6.81?4.11)h vs.(5.55?2.35)h,AUC0～24(10.60?7.70)ng?h?mL-1 vs.(9.90?6.76)ng?h?mL-1,AUC0～∞(11.30?7.90)ng?h?mL-1 vs.(10.20?7.00)ng?h?mL-1.The relative bioavailability of domestic nisoldipine tablets was(110.3?30.8)%.CONCLUSION:The reference preparation and the test preparation of nisoldipine tablets were proved to be bioequivalent.

OBJECTIVE:To investigate the effectiveness and economics of 10 mg/d rosuvastatin and 20 mg/d atorvastatin in the treatment of hyperlipidemia (HLP). METHODS:The information of 180 HLP patients selected from Tianmen Municipal First People's Hospital during Mar. 2015-Feb. 2016 were divided into group A and B according to medication regimen,with 90 cases in each group. Group A was given Atorvastatin calcium tablet 20 mg,qd;group B was given Rosuvastatin calcium tablet 10 mg,qd. Treatment course of 2 groups lasted for 8 weeks. Blood lipid indexes before and after treatment,lipid-lowering efficacy,the rate of qualified blood lipid and the occurrence of ADR after treatment were compared between 2 groups. Cost-effectiveness analysis was adopted for economic evaluation. RESULTS:Before treatment,there was no statistical significance in the levels of blood lipid in-dexes between 2 groups (P>0.05). After treatment,TC and LDL-C levels of 2 groups were significantly lower than before treat-ment,and those of group B were significantly lower than those of group A,with statistical significance(P<0.05). Total response rate of lipid-lowering in group B(97.78％)was significantly higher than group A(86.67％),and the rate of qualified blood lipid (66.67％)was also significantly higher than group A(51.11％),with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). The costs of group A and B were 488.32,436.24 yuan,and cost-effectiveness ratios were 5.63,4.46;incremental cost-effectiveness ratio was -4.69. The plan of group B had cost-effective-ness advantage. The results of cost-effectiveness analysis were supported by sensitivity analysis. CONCLUSIONS:In the view of short-term efficacy,10 mg/d rosuvastatin plan is better than 20 mg/d atorvastatin plan in lowering lipid and has cost-effectiveness advantage,and both have similar safety.

To study the proliferation characteristics of PPV in differently infected way and the variance of concentrations in different cells. A strain of porcine parvovirus(PPV) was adapted to PK-15 cells, and a Real-time fluorescent quantitative PCR (FQ-PCR) assay was developed based on the specific region of the NS1 gene of PPV to quantify the PPV. The FQ-PCR was used to measure the viral concentration of virus-infected cells by simultaneous or step by step inoculation and plot one-step growth curves. The proliferation characteristics of PPV strain in different cells lines (HeLa, MDBK, PK-15 ,ST, F81, BHK-21 and Marc-145) was also compared. The results showed the PK-15 cell -adapted strain of PPV produced CPE after 12 passages, and maintained stable CPE at the following 10 messages. The one-step growth curve showed that the virus concentration of simultaneous inoculation was higher than that of the step-by-step inoculation, and the proliferation cycle of step-by-step inoculation was shorter. The proliferation ability of PPV strain in different cells showed that CPE appeared first inPK-15, followed by ST, HeLa and MDBK, and the virus concentration was highest in ST, followed byPK-15, MDBK and HeLa. NO proliferation was observed in F81, BHK-21 and Marc-145 cells. These findings lay a material foundation for the basic researches on PPV and the development of vaccine.
