Objective To evaluate the precision of the ACCU-CHEK Performa glucose monitor,the Optium Xceed glucose monitor,the Breeze glucose monitor and the Contour glucose monitor.Methods A total of 102 patients (diabetic patients or un-diabetic patients) who visited our endocrinology outpatient department were randomly selected.The venous blood samples were collected using the laboratory auto-analyzer,and the synchronous finger tip capillary blood were collected using the ACCU-CHEK Performa glucose monitor and the Optium Xceed glucose monitor,or using the Breeze glucose monitor and the Contour glucose monitor.Results The correlation coefficients between VPG by the laboratory auto-analyzer and CBG by the four kinds of glucose monitors was good,and R values were 0.990,0.985,0.963,0.952,and there was no significant difference between the CBG of Breeze glucose monitor and the same VPG(P ＞ 0.05).When the blood glucose concentration was higher than 4.2mmol/L,and compared with the VPG detected by synchronous measurement laboratory,95％ of the CBG test results detected by four kinds of blood glucose meters were in the range of ± 20％.Conclusion The four kinds of glucose monitors can provide high accurate.

Objective:To investigate the role of Leukotactin-1(LKN-1),CC receptor 1(CCR1)and CC receptor 3(CCR3)in the pathogenesis of hypertensive disorder complicating pregnancy(HDCP),the expressions of these factors in placentas were measured.Methods:The levels of LKN-1,CCR1 and CCR3 in placentas were measured from 32 patients with HDCP(study group)and 32 normal pregnant women(control group)by western blot(WB).The localization of these factorsin placentas were detected by immunohistochemistry(IHC).Results:LKN-1 protein expression was negative in placentas from the two groups by WB and IHC,while both CCR1 and CCR3 in the HDCP group were significantly lower than those in the control group(CCR1 0.66±0.06 vs 0.88±0.03.CCR3 0.17±0.01 vs 0.27±0.01,P<0.01).CCR1 was localized in vascular endothelial cells and stroma cells in both groups,but rare in the trophoblast layer.CCR3 was localized in vascular endothelial cells and trophoblast cells in both groups.Conclusions:There is no LKN-1expression in placentas from the two groups.Down regulation of CCR1 and CCR3 may associate with the pathogenesis of HDCP.

Objective To examine the effects of formaldehyde on the process of sperm development and reproductive capacity in male mice and the micronucleus rate of liver cells from offspring.Methods The mice were randomly divided into negative control group(NC),formaldehyde exposed group and positive control group (PC).The exposed dose was 21 mg?m-3 (1/24 LC50),42 mg?m-3 (1/12 LC50) and 84 mg?m-3 (1/6 LC50),respectively. 12 male mice were included in each group.Male mice from different formaldehyde exposed groups were inhaled with formaldehyde for 2 h one day,6 d each week,lasted for 13 weeks.The aberration rate of sperm in male mice and the micronucleus rate of liver cells from offspring were observed,and the reproductive capacity of male mice was detected by dominant lethal test.Results The aberration rates of sperm in mice from different formaldehyde exposed groups were significantly higher than that in negative control (P

By feeding rats with high-fat diet insulin resistant models were induced.Some of the models were treated with intragastric administration of curcumin,then the effects were evaluated by hyperinsulinaemic-euglycaemic clamp technique.Curcumin reduced the level of serum resistin and the expression of resistin mRNA in adipose tissue,and thus ameliorated insulin resistance in rats.

Objective To explore the distribution on-511C/T,-31T/C single nucleotide polymorphism of IL-1β gene among Uygur population in Xinjiang,and to analyze the correlation between IL-1β gene polymorphism and depressive disorders.Methods A total of 100 patients with depressive disorders and 120 control subjects were selected.Polymerase chain reaction and restriction fragment length polymorphism (RFLP-PCR),enzyme digestion and sequence reaction were used to detect the common-511C/T,-31T/C polymorphism of the IL-1β gene.The relationship between the polymorphism in the IL-1β gene and the severity of depressive disorders was analyzed.Results The frequencies of CC,CT,TT in-511 were 19.0％,58.0％ and 23.0％ in patient group,while those were 19.2％,55.0％,25.8％ in the control group,which did not show statistically significant differences (x2=0.266,P=0.875).The frequencies of CC,CT,TT in-31 were 24.0％,58.0％ and 18.0％ in the patient group,while those were 24.2％,58.3％,17.5％ in the control group,which did not show statistically significant differences (x2=0.0093,P=0.995).The frequencies of CC,CT,TT genotypes of the IL-1β gene polymorphism (-511 C/T,-31 T/C) were not statistically different between depressive patients and healthy controls.Conclusion The findings suggest no significant association between-511C/T,-31T/C polymorphism and depressive disorders in Uygur population of Xinjiang.

[ ABSTRACT] AIM:To establish the insulin resistance rat model for evaluating the correlation of omentin-1 level and insulin resistance.METHODS: SPF male Wistar rats ( n =30 ) were randomly divided into normal control group (NC, n=15) and high-fat diet group (HF, n=15).The rats in NC group were fed with basic diet.The insulin resistant model was established by feeding the rats with high-fat diet in HF group.After 10 weeks, 5 rats in each group were as-sessed by the technique of hyperinsulinaemic-euglycaemic clamp.After the insulin resistant model was successfully estab-lished, the body weight and fasting blood glucose were detected.The concentration of fasting serum omentin-1 was analyzed by ELISA.Fasting serum insulin was measured by radioimmunoassay.RESULTS: No difference of fasting blood glucose between the 2 groups was observed.The level of fasting serum insulin in HF group was significantly higher than that in NC group ( P <0.05 ) .The level of serum omentin-1 in HF group were significantly decreased compared with NC group (P<0.01).Pearson’s correlation analysis showed that negative correlations between serum omentin-1 and fasting serum insulin (r=-0.654,P<0.01), serum omentin-1 and free fatty acid (r=-0.446, P<0.05) was found.CONCLU-SION:In rats, serum omentin-1 level began to decrease at insulin resistance stage.As serum omentin-1 level decreased, the basal insulin level increased, indicating that decreased serum omentin-1 level may be an early factor of IR, diabetes and cardiovascular diseases.

Objective To develop a new flow-injection chemiluminescence(FI-CL) method for the determination of acyclovir and gancyclovir by using the CL system of Ce(IV)-Rhodamine B.Methods The redoxreaction of Ce(IV) and acyclovir/gancyclovir in H2SO4 medium could generate CL signal.Rhodamine B could obviously sensitize this signal,and the CL intensity was proportional to the concentration of acyclovir and gancyclovir.Therefore,a new FI-CL method has been described for the determination of acyclovir and gancyclovir.Results For acyclovir,the determination range was 3.0?10-5g/L-7.0?10-2g/L,with 1.56?10-5g/L as its determination limit.During 11 repeated measurements for 1.0?10-3g/L acyclovir,the relative standard deviation was 2.08%.For ganciclovir,the determination range was 5.0?10-5g/L-7.0?10-2g/L,with 2.35?10-5g/L as its determination limit.The relative standard deviation was 2.83%,with 11 repeated measurements of 1.0?10-3g/L ganciclovir.Conclusion This method has broad linear range,high sensitivity,and convenience and speediness,it therefore,can be successfully used to determine the content of ganciclovir in injections.
