Objective To investigate the levels and clinical significance of the ratio of apolipoprotein B(apoB)and apolipoprotein A1(apoA1)in the patients with cerebral infarction,and to determine the critical value of apoB/apoA1 inthe patients with ischemic cerebral infarction.Methods 126 inpatients with cerebal infraction diagnosed by MRI enhancement scanning of the head in our hos-pital.From November 1,2012 to May 15,2013 were selected.Among them,51 cases were common carotid artery intima-media thickening(carotid artery intima-media >0.9 mm)and 75 cases were carotid artery intima-media non-thickening by the color ultra-sonic examination;81 cases had atherosclerosis plaque and 45 cases had no atherosclerosis plaque.57 individuals with healthy physi-cal examination were selected as the control group.The fasting serum samples were collected from all the research subjects.The in-dexes of TG,CHOL,HDL-C,LDL-C,apoB,apoA,etc.were detected.Then the independent t-test was adopted to analyze and com-pare the ratio of apoB/apoA1 and others related indictors(including TG,AIP,apoB,apoA1,etc.)in the various groups.The ROC curves were made,the area under the curve was read and the specificity and sensitivity of apoB/apoA1 for diagnosing ischemic cere-bral infarction were calculated.Results (1)AIP and the ratio of apoB/apoA1 in the ischemic cerebral infarction patients were high-er than those in the control group,the rise rate of apoB/apoA1 ratio in the ischemic cerebral infarction patients was 5.43 times of that in the control group,especially the patients with carotid atherosclerosis or carotid artery intima-media thickenning were more significant,while TG and apoB had no obvious changes.(2)the ratio of apoB/apoA1 had no obvious difference between the carotid artery intima-media thickening group and the carotid artery intima-media non-thickening group,while which in the atherosclerotic plaques group was significantly increased compared with no carotid atherosclerosis group and 1.6 times of that in the normal control group.So it could be considered that the apoB/apoA1 ratio was a specific indicator for atherosclerosis.(3)In the diagnosis of ische-mic cerebral infarction,the area under the apoB/apoA1ROC curve was 0.86.its specificity and sensitivity were higher than other in-dexes.Conclusion The apoB/apoA1 ratio is the most specific and sensitive index in the patients with ischemic cerebral infarction and has good correlation with ischemic cerebral infarction,especially in the presence of carotid atherosclerosis plaque it is more sen-sitive,and is a good index of laboratory diagnosis of ischemic cerebral infarction.

Objective To investigate the relationship between endothelial damage and p120-catenin (p120-ctn) in a model of paraquat intoxication,and the modulatory effect of mangiferin on p120-ctn.Methods Human umbilical vein endothelial cells (HUVECs) were cultured in two compartment spreading apparatus in vitro.The endothelial cells were divided into three groups:control group (cultured in DMEM with 10％ fetal bovine serum),paraquat group (paraquat was added to the medium with final concentration of 0.05 μmol/L) and mangiferin group (cultured in medium with addition of paraquat for 30 minutes,then mangiferin was added in a final concentration of 20 μmol/L).The cellular permeability at 6,12,24,48,72 hours after culture in the three groups was measured.The expressions of p120-ctn 1A,p120-ctn 3A mRNA and p120-ctn protein were measured by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot analysis.The distribution of p120-ctn protein was observed by immunofluorescence.Results Compared with control group,cellular permeability in paraquat and mangiferin groups were increased with prolongation of time,and peaked at 72 hours [(29.86 ± 3.98)％,(24.39 ± 2.79)％ vs.(11.71 ± 1.67)％,both P＜0.05].The cellular permeability was significantly lower in mangiferin group than that in paraquat group at different time points (all P＜0.05).At 6 hours after intoxication,the expressions of p120-ctn 1A,p 120-ctn 3A mRNA (gray value) and p 120-ctn protein (gray value) were significantly lower in paraquat group than those in control group (p120-ctn 1A mRNA:0.150 ± 0.024 vs.0.433 ± 0.024,p120-ctn 3A mRNA:0.316 ± 0.043 vs.0.701 ±0.020,p120-ctn protein:0.485 ±0.031 vs.0.763 ±0.038,all P＜0.01).The expressions of p120-ctn 1A,p120-ctn 3A mRNA and p120-ctn protein were significantly higher in mangiferin group than those in paraquat group from 6 hours on (p120-ctn 1A mRNA:0.281 ± 0.021 vs.0.150 ± 0.024,p120-ctn 3A mRNA:0.602 ± 0.042 vs.0.316 ± 0.043,p120-ctn protein:0.675 ± 0.031 vs.0.485 ± 0.031,all P＜0.01),and they were gradually increased with prolongation of time,and peaked at 72 hours (p120-ctn 1A mRNA:1.376 ±0.128 vs.0.150 ± 0.024,p120-ctn 3A mRNA:1.251 ± 0.059 vs.0.316 ± 0.043,p120-ctn protein:0.844 ± 0.050 vs.0.485 ± 0.031,all P＜ 0.01).Under upright fluorescence microscope,p120-ctn was mainly distributed in the cell membrane in control group,with a slight expression in cytoplasm,and no expression in the nuclei.With prolongation of time,p120-ctn expression in the cell membrane was gradually decreased in paraquat group,while it was increased in the cytoplasm and nuclei,with blurring of cell membrane and widening of cellular gap.p120-ctn expression was improved on the cell membrane in mangiferin group at corresponding time points,with decreased in expression in nuclei and cytoplasm.Conclusion The p120-ctn protein plays an important role in the enhancement of endothelial permeability in paraquat intoxication,and mangiferin may attenuate endothelial injury in paraquat intoxication possibly through modulation of p 120-ctn protein.

This study was designed to assess the immune protective effects of the vaccine strain of a precocious line of Eimeria necatrix with different doses and at different immunization times. The immunizations had a negative effect on weight gains of chickens to a certain degree but could be compensated during the “compensatory growth period” after immunity was established in the chickens. The number of oocysts excreted was positively correlated with the immunization dose. All the immunized chickens, whether they were immunized once or twice or immunized with different doses of sporulated oocysts, were able to resist attack from 1x105 virulent sporulated oocysts of E. necatrix. The lesion scoring showed that no significant difference existed in the chicken groups immunized with different doses (300 and 600) of sporulated oocysts. However, a difference existed in the immune homogeneity established in the different immunized groups, and two artificial immunizations were superior to one artificial immunization, indicating that two could extend the duration of oocyst excretion and allow more chances for the immunized chickens to become repeatedly infected.

OBJECTIVE: We previously found the hepatoprotective effects of metformin (Met) in mice with lipopolysaccharide/D-galactosamine (LPS/D-Gal)-induced endotoxic liver injury, the present studies were designed to further explore the potential association between the hepatoprotective effects of Met and catalse (CAT). METHODS: Acute liver injury was induced by intraperitoneal injection of LPS/D-Gal. The activity of hepatic CAT was determined and whether the CAT inhibitor aminotriazole (ATZ) could abolish the protective effects of Met was tested. RESULTS: Met enhanced the activity of CAT in the liver of LPS/D-Gal-exposed mice, suppressed the elevation of hydrogen peroxide (H2O2) and malondialdehyde (MDA). The CAT inhibitor ATZ obviously suppressed the stimulatory effects of Met on CAT activity, but ATZ partially reversed the suppressive effects of Met on H2O2 content. ATZ did not reverse the inhibitory effects of Met on MDA production or ALT and AST elevation, it has no effects on morphological abnormalites. CONCLUSION: These data suggest although Met can improve the activity of CAT in LPS/D-Gal challenged mice, these effects seem not important for the protective benefits of Met.

In order to promote the Shenqifuzheng injection (SQFZ) clinical medication safety, this study reevaluate on SQFZ post marketing safety study systematically. Including multi center large sample registration type safety monitoring research, the analysis based on national spontaneous reporting system data, the analysis based on the 20 national hospital information system data and literature research. Above the analysis, it suggests that SQFZ has good security. The more adverse drug reaction (ADR) as allergic reactions, mainly involved in the damage of skin, appendages and its systemic damage, serious person can appear allergic shock. ADR/E is more common in the elderly, may be related to medication (tumor) populations. Early warning analysis based on SRS data and literature research are of the view that "phlebitis" has a strong association with SQFZ used.
