Objective To investigate the effect of vitamin D (VD) on macrophage to phagocytize Staphylococcus aureus (SA). Method Macrophoge cell lines RAW264.7 were allocated into 3 groups:control group(C),bacterium group(B),active vitamin D+ bacterium group (VD+B). Cells in the VD+B group were incubated with 10-8mol/L active vitamin D for 24h,then cells in the VD+B group and the B group were cultured with SA for 1h,and phagocytosis rate,mitochondrial membrane potential,[Ca～(2+)]i,reactive oxygen species were determined by flow cytometry (FCM). Results The phagocytizing activity of macrophage in VD+B group was significantly higher than that in B group 1h after infection,At the same time,the mitochondrial member potential and [Ca～(2+)]i of macrophage in VD+B group were distinctly lower than that in B group; but reactive oxygen species of macrophage in the VD+B group was insignificantly different from B group. Conclusion Vitamin D can reinforce the phagocytizing activity of macrophage and inhibit the apoptosis of macrophage after phagocytize Staphylococrcus aureus.

OBJECTIVE To investigate the effect of arctigenin(ATG) on liver fibrosis in rats induced by carbon tetrachloride(CCl4)and to explore its underlying mechanism. METHODS Sprague-Dawley rats were randomly divided into six groups:vehicle,ATG 3.0 mg · kg-1 group,CCl4 model group,CCl4+ATG 1.0 and 3.0 mg·kg-1 groups,and CCl4+colchicine(COL)0.1 mg·kg-1(toxicity)group. Liver fibrosis was induced by subcutaneous injection of CCl4 in rats for 8 weeks. ATG and colchicine were administrated ig once a day starting from the fifth week after the CCl4 treatment for 4 weeks subsequent. At the end of the study,glutamic pyruvic transaminase (GPT),glutamic oxaloacetic transaminase(GOT),albumin(ALB),and total bilirubin (TBIL) as well as the contents of hydroxyproline (HYP) in liver tissues were measured. Histopathological changes were observed in the liver tissues using hematoxyline-eosin(HE)and Masson’s trichrome staining. The proliferation of hepatic stellate cells (HSC) and expression of cell cycle-related proteins were assayed by indirect immunofluores?cence staining and Western blotting,respectively. RESULTS Compared with CCl4 model group,ATG 1.0 and 3.0 mg · kg-1 improved the liver function by decreasing serum contents of GPT,GOT and TBIL (P<0.05),and increasing serum content of albumin(P<0.05). Histological results indicated that ATG 1.0 and 3.0 mg · kg-1 alleviated liver damage and reduced the formation of fibrous septa. Moreover, ATG 1.0 and 3.0 mg · kg-1 significantly decreased liver HYP when compared with CCl4 model group(P<0.05). In addition,CCl4-induced proliferation of activated HSC was inhibited by ATG 1.0 and 3.0 mg·kg-1, and this was accompanied by down-regulation of cyclin D1,cyclin-dependent kinase(CDK)2,CDK4, and proliferating cell nuclear antigen (PCNA)(P<0.05),and up-regulation of p27kip1 in activated HSC (P<0.05). CONCLUSION ATG can alleviate hepatic injury and fibrosis induced by CCl4,which is probably associated with suppression of the proliferation of activated HSC.

Objective To compare the effects of different antiplatelet therapy on outcomes in patients with acute coronary syndrome (ACS). Methods 338 hospitalized patients with ACS were enrolled. They were assigned to three groups: group 1, aspirin alone after discharge, n=93; group 2, dual antiplatelet treatment of aspirin and clopidogrel after discharge for 6～12 months, then aspirin, n=127; and group 3, dual antiplatelet treatment of aspirin and clopidogrel after discharge for 2 years, n=118. All the patients were followed up for 2 years. The clinical data (basic clinical data, platelet count and serum lipids indeices), primary end point (cardiovascular death, nonfatal myocardial infarction and stroke) and hemorrhagic events (major hemorrhage, moderate hemorrhage and minor hemorrhage) within 1 and 2 years were analyzed. Results During 1 and 2 years, compared with group 1, the incidence of cardiovascular death and all primary end points of groups 2 and 3 decreased significantly (P＜0.05), but the nonfatal myocardial infarction and stroke did not （P＞0.05）. The difference was not statistically significant between groups 2 and 3 in all the end points （P＞0.05）. The difference of hemorrhagic events was not statistically significant among the 3 groups（P＞0.05）. Conclusion Dual antiplatelet treatment of clopidogrel plus aspirin for 2 years may decrease the mortality of cardiovascular disease while the incidence of severe hemorrhage doesn't increase.

Objective To observe the efficacy and safety of recombinant human endostatin injection (en-dostar) combined with GP(gemcitabine plus cisplatin)regimen in patients with advanced non- small cell lung cancer (NSCLC). Methods Thirty seven histologically confirmed advanced NSCLC patients were enrolled in the group. The patients were administered with endostar 15 mg from day 1 to 14,gemcitabine 1 000 mg/m2 day 1 and 8,cisplatin 80 mg/m2 on days devided into 1 - 3, repeated 21 days. Each patient should complete two cycles. Results 37 patients were valuable for response. One patient achieved complete response(CR), 15 partial response(PR), 14 stable disease (SD) ,and 7 were found to have disease progression(PD). The total response rate was 43.2% ,median TIP was 5.2 months. The main toxicities was leukopenia. There was no treatment-related death in this series. Conclusion En-dostar combined GP regimen was effective and safe in treatment of advanced NSCLC.

Objective To detect the genetic association between schizophrenia and polymorphism of phosphodiesterase 4B (PDE4B) gene. Methods Observed in a sample of 98 parent/offspring trios where the proband net the Amerecan Classification and diagnostic Criteria for Mental Disorders The Forth Revised Edition,criteria for schizophrenia using correlation analysis and haplotype relative risk analysis. The polymorphism of phosphodiesterase 4B gene was detected with PCR methods and SNP typing in all nucleus families. Results The rs2180335 al-lele was connected with schizophrenia (P = 0.02131). Allele A was protective factor (Z = -2. 184) and allele G was the hazard factor (Z = 2.184). The frequency of rs2180335 allele A was 0.452 and the allele G was 0.548. The rs1040716, rs 3767311 and rs472952 allele was independence with schizophrenia. Five kinds haplotypes of A/A in the rs2180335-rs3767311, A/A in the rs 3767311-rs472952, A/A/A in the rs2180335-rs3767311-rs472952,A/G/G/A and T/A/A/A in the rs1040716-rs2180335-rs3767311-rs472952 associated with schizophrenia (P values were 0. 028715,0. 034845,0. 024177,0. 023967,0. 010839,genotype frequencies were 0. 223, 0.223,0.127,0.081,0.073). Conclusion It shows an association between schizophrenia and the rs2180335 polymorphism at nucleotide of phosphodiesterase 4B gene in Chinese.

Objective To investigate the relationship between with or without non?alcoholic fatty liver disease(NAFLD) and diabetic retinopathy(DR) in type 2 diabetes mellitus(T2DM)?Methods Clinical and laboratorial data of 517 cases T2DM hospitalized patients were collected,and the patients were divided into two groups according to if the NAFLD was complicated or not?Group A was T2DM with NAFLD and group B was T2DM without NAFLD?The general information and the laboratorial checking results were Compared, then various index were used as the independent variable, DR was used as the dependent variable for Logistic regression analysis?Results (1)In the 517 cases of T2DM patients,the incorporative rate of the NAFLD was 65?7%(349/517)?(2)Compared with group B,the levels of body mass index(BMI),insulin resistance index (HOMA?IR),glutamyltransferase(GGT),alanine aminotransferase(ALT),aspartate aminotransferase(AST), triglyceride(TG),total cholesterol(TC),low?density lipoprotein cholesterol(LDL?C) and uric acid(UA) for group A were significantly increased, while the high?density lipoprotein cholesterol ( HDL?C ) level was significantly decreased?All the differences were statistically significant( P<0?05)?( 3) Logistic analysis showed that the duration of the extension,hypertension,the increasing level of NAFLD,LDL?C were the risk factors of DR?Even though excluded the influence of duration,high blood pressure and LDL?C level,NAFLD was still the risk factor for T2DM complicated by the DR( OR=2?176,95% CI ( 1?354,3?199) )?Conclusion NAFLD and DR are closely related, so early diagnosis and intervention of NAFLD may prevent the occurrence and development of DR.
