OBJECTIVE To investigate the drug resistance of Escherichia coli in biliary tract infection and genotype of ESBLs.METHODS Antimicrobial susceptibility test was performed using Kirby-Bauer method.The genotypes of ESBLs were detected by PCR.RESULTS The detection rate of ESBLs producing bacteria was 32.4%(23 strains),and the drug-sensitivity test indicated that E.coli was sensitive to imipenem,meropenem and cefoperazone/subactam,but these ESBLs producing strains were resistant to other antimicrobial agents.ESBLs were identified as TEM type in 16 strains,SHV type in 4 strains,CTX-M type in 12 strains and OXA type in 5 strains.CONCLUSIONS ESBLs-producing E.coli in biliary tract infections show strous resistance.TEM and CTX-M are the most common ESBLs genotypes.

Totally 1136 individuals aged over 40 underwent health check up in March to May 2009. Fasting blood glucose, 2-h post-challenge blood glucose, glycated hemoglobin A1c ( HbA1c), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and serum uric acid were measured. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Criteria. The results shows that total body fat, region body fat indices, blood pressure, blood glucose and serum uric acid levels increased with the age ( P < 0.01) . The prevalence rate of metabolic syndrome in this group of individuals were 15. 1% (171/1136) , and increased with age (P<0.01). The most common combination of metabolic syndrome was central obesity-hypertension-dyslipidemia (40. 9% , 70/171). Unconditional logistic regression revealed that waist-hip-ratio, body mass index and uric acid were the risk factors for metabolic syndrome.

A total of 1342 individuals underwent physical examinations according to the criteria of metabolic syndrome of International Diabetes Federation (IDF) in 2005.And 314 patients with metabolic disorders were screened for diabetes by standard meal and methods oral glucose tolerance test (OGTT).Newly diagnosed diabetics was 12 (4.1％ ) vs.17 (5.8％) respectively.No significant difference existed between two methods (P =0.332).Kendall's (τ)b =0.313,Kendall's (τ)c =0.208 and Gamma coefficient =0.580 (P =0.000).The mixed meal method was correlated with OGTT,Kappa =0.258 (P =0.000) and two methods were consistent.Diabetic screening should be stressed in the subjects with metabolic abnormalities.And the detecting efficiency of postprandial plasma glucose is similar to OGTT.

Objective This study was to investigate the association of certain single nucleotide polymorphisms (SNPs) of the ER with genetic susceptibility to ISS .Methods Genomic DNA was extracted from peripheral blood of children with ISS (n=355) and of normal growth and development individuals as controls from Jiangxi province (n=345) .The association between the ER gene polymorphisms with the height-related clinical traits was analysed .Results The allele T of rs6557177 is significantly lower in the ISS group than in the control group(P=0 .021 ,OR=0 .624) .The clinical indexes of two kinds of different genotypes were analyzed and compared ,there was no statistical difference(P>0 .05) .Conclusion The allele T of rs6557177 of ER gene is a protection factor of ISS .C gene and T gene grouping clinical parameters (hight ,weight ,IGF-1 ,IGFBP3 ,E2 and BMI) were analyzed and found no statistically significant difference .

In order to compare the difference of cyp2e1 gene expression between patients with hepatic cirrhosis and obstructive jaundice,and to investigate the pharmacologic significance behind this difference,liver samples were obtained from patients undergoing hepatic surgery with hepatic cirrhosis( n =7),obstructive jaundice( n =6) and normal tissue of hepatic angioma (controls, n =6). Total hepatic RNA were extracted using the one step method, cyp2e1 cDNA probe prepared by primer randomly marked method, and difference of cyp2e1 expression was compared among patients by Northern blotting.Compared with control group, the expressions of cyp2e1 in liver tissue among patients with obstructive jaundice were evidently reduced, while expression of this gene in cirrhosis liver was unaltered. CYP2E1 isoenzyme encoded by cyp2e1 decreased among patients with obstructive jaundice as expression of cyp2e1 gene significantly reduced, liver ability for metabolism of inhalant anesthetics declined consequently, under some special conditions, hepato nephric toxicity of anesthetics might be aggravated.

Objective To explore the acute toxicity and LD 50 of Tripterygium Hypoglaucum (Levl) Hutch(THH) solution to provide information for safe clinical application. Methods After oral administration of THH solution in mice, the mortality and the physiological and pathological changes were observed. Results The LD 50 (95% confidence limit) of THH in male and female mice was 79 g/kg(69～89 g/kg) and 100 g/kg (90～112 g/kg), respectively. No marked pathological change of the organs was found. Conclusion According to the standard of grading of acute toxicity, THH solution belongs to the moderate class. Therefore, it is safe in clinical practice and has a wide application.
