Objective To analyze the relation between glycosylated hemoglobin (HbA1c) and coronary heart disease (CHD) among diabetic and non-diabetic individuals.Methods A total of 1190 in patients from January 2009 to September 2009 were selected and divided into two groups:225 patients with diabete mellitus and 965 patients without.We collected the age,sex,triglyceride ( TG),total cholesterol ( CHO),high-density lipoprotein ( HDL-C),low-density lipoprotein ( LDL-C),fasting blood-glucose (FBG),glycosylated hemoglobin (HbA1c),high-sensitivity CRP (hs-CRP) and analyzed the relation between these indexes and CHD in diabetic and non-diabetic individuals respectively,then,analyzed the difference of HbA1c between patients with and without CHD after correcting the differentiating factor with a multivariable-adjusted model.Meanwhile,according the HbA1c level,we divided all participants into four groups:4.0％ -5.4％( Ⅰ),5.5％ -5.9％ ( Ⅱ),6.0％ -6.4％ ( Ⅲ),≥6.5％ ( Ⅳ),and observed the distribution of HbA1c and coronary heart disease in diabetic and non-diabetic individuals respectively.Results ( 1) In non-diabetic individuals,statistically significant difference of male( 80.5％ υs 62.7％),age [ ( 59 ±11) years υs (55 ± 11) years],FBG [(5.62 ± 1.48) mmol/L υs (5.30 ±0.84) mmol/L],HbA1c [(5.98±0.92)％ υs (5.65 ±0.53)％],CHO [(4.48 ±1.01) mmol/L υs (4.77 ±1.04) mmol/L],LDL-C [(2.59±0.87) mmol/L υs (2.79 ±0.86) mmol/L],HDL-C [(1.08 ±0.26) mmol/L υs(1.21 ±0.32) mmol/L] was observed between patients with and without CHD (P ＜0.01),however,in diabetic individuals,only LDL-C [ ( 2.56 ± 0.81) mmol/L υs ( 3.07 ± 0.90) mmol/L],CHO [ (4.44 ±0.95) mmol/L υs ( 5.08 ± 1.16) mmol/L] were observed ( P ＜ 0.0 1).(2) In all participants,the higher of HbA1c,the higher of CHD percent,compared to patients without CHD,the percent of high HbA1c in CHD patients was significantly higher.After adjusting for age,sex,HDL-C,HbA1c was an independent risk marker for CHD in non-diabetic individuals ( OR:1.935,95％ CI:1.356 - 2.762,P ＜ 0.05),however,links between FBG in the non-diabetic range and CHD appeared weaker after controlling indexes listed above( OR:1.507,95％CI:1.082 -2.098,P＜0.05).Conclusion HbA1c is an independent risk factor for CHD in nondiabetic individuals and prior to FBG.

Objective To assess the effect of polygonum peffoliatum L on the expression of Hypoxia inducible factor-1 (HIF-1α) and vascular endothelia growth factor (VEGF) in hepatic fibrosis rats induced by Dimethylnitrosamine (DMN) . Methods Seventy-two SD rats were randomly divided into six groups, after the model of HF rat induced by DMN and intervened by different concentrations of Polygonum perfoliatum L. Conventional flaking of liver and HE were used to observed histopathological change. Immunohistochemstry was used to detect HIF-1αand VEGF in hepatic tissues of hepatic fibrosis rats. Results The expression of HIF-1α and VEGF in hepatic fibrosis rats of the high dose of Polygonum perfoliatum L from (-) to (3 +) were one , nine, one, zero and one, eight, two, zero, respectively. The expression of HIF-1α and VEGF in hepatic fibrosis rats of the middle dose of Polygonum perfoliatum L from (-) to (3 +)were one , seven, two, zero and one, six, three, zero, respectively. Compared with the model group, the high and middle dose of Polygonum perfoliatum L can reduce the expression of HIF-1 oand VEGF in hepatic fibrosis rats (P ＜ 0. 01). Conclusions Polygonum peffoliatum L has a good curative effect of anti hepatic fibrosis. Its therapeutic mechanism mainly maybe due to adjust the metabolism of extracellular matrix by decreasing HIF-1 αand VEGF expression.

OBJECTIVE:To explore the risk factors of adverse reaction of cefazolin drugs by Logistic model. METHODS:Re-lated information was collected from the information system of our hospital,and SPSS 19.0 software was conducted for statistical analysis. RESULTS:Totally 855 patients were enrolled,30 of which had adverse reactions(3.51%). According to the results of Logistic analysis,intravenous administration with the concentration of ≥20 mg/ml (OR=7.857,95% CI:1.566-39.431,P=0.003) was the risk factor of adverse reaction of cefazolin drugs when single dose was above 2 g (OR=13.75,95% CI:2.423-78.028,P<0.001)at 0:00-8:00(OR=2.340,95% CI:1.043-5.253,P=0.034). CONCLUSIONS:Adverse reaction of ce-fazolin drugs might be dose-related type. The drug adverse reaction predictive thresholds are single dose above >1.75 g with ad-ministration time of 0:00-9:05 and concentration of above 7 mg/ml. According to the predictive thresholds,the risk of patients with adverse reaction can be predicted to promote safe and effective use of cefazolin.

Objective To study the anti-neuroglioma effect of methyl-mercuric chloride(MMC) by observing the morphological changes of apoptotic neuroglioma cells induced with MMC in rats with brain neuroglioma.Methods The rat models of neuroglioma were established,and divided into two groups.The rats in experimental group were lavaged with MMC 1 week after injected with C6 glioma cells,10 mg?kg-1every day,the rats in control group were treated with sodium chloride at the same dose.24 d after inoculation all rats were sacrificed except natural death,the brain tissues were obtained,and the pathohistological changes were observed under light microscope and transmission electron microscope.Results The macropathological result showed that the tumor volume in experimental group was smaller than that in control group.Under light microscope,in experimental group the growth density of C6 ghioma cells was lower than that in control group,and the apoptotic cells with smaller volume and karyopyknosis were found.The result of transmission electron microscope showed that in experimental group,the glioma cells had some changes such as karyopyknosis,chromoplasm margination,nuclear fragmentation and vacuolar degeneration and so on.Conclusion MMC has inhibitory effect on the proliferation of C6 glioma in rats in vivo,its mechanism may be related to inducing the apoptosis of neuroglioma cells.
