Objective To investigate the characteristics of distribution and the changes in drug resistance of Enterococci,providing reference for clinical treatment.Methods The distribution and drug resistance in 2547 clinical isolates of Enterococci from 2001 to 2007 in Huzhou Central Hospital and the First People's Hospital of Huzhou were retrospectively analyzed.Results A total of 2547 strains of Enterococci were isolated from 94876 clinical specimens(2.68%),in which Enterococcus faecalis wag primary and Enterococcus faecium Wag ranking the second.The positive rate of Enterococci in urine specimens was the highest,and that in sputum specimens was increasing recently.Enterococci showed higg resistance to erythromycin,rifampin,ciprofloxacin and levofloxacin;Enterococcus faecalis Wag more sensitive to penicillin,ampiciilin and ndtrofurantoin than Enterococcus faecium,while Euterococcus faecium was more sensitive to chloramphended and tetracycline than Enterococcus faecalis;both of them were sensitive to vaneomycin and teicoplanin.Conclusions Enterococcus faecalis and Enterococcus faecium are the common pathogen in Enterococci infections.Enterococci show high drug resistance,so the clinical use of antibiotics should be based on the resuhs of drug sensitivity test.

Objective To study the correlation between individual gene polymorphisms of transforming growth factor (TGF)-β1 + 869 T/C,tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) + 1525 G/A genes and nodular thyroid disease.Methods From September 2007 to December 2009,a total of 544 patients with nodular thyroid disease diagnosed in the Department of Endocrinology,The First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology were selected,including 136 cases of nodular goiter patients (node group),132 cases of thyroid tumor (adenoma group),146 cases of Graves patients (GD group),and 130 cases of Hashimoto's thyroiditis (HT group).One hundred and thirty-five healthy subjects were enrolled as control group.Two milliliters of fasting venous blood of all subjects were collected.Polymorphisms of the TGF-β1 + 869 T/C and the TRAIL 1525 A/G genes were identified by the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and the restriction fragment length polymorphism (PCR-RFLP) methods.Results TGF-β1 + 869 T/C:The CC genotypes and C allele frequencies of nodular goiter group [47.0％(64/136),63.2％(172/ 272)] were significantly higher than those of normal control group [18.0％(22/135),45.2％ (122/270); x2 =30.76,17.79,all P ＜ 0.05].The genotypes and allele frequencies of adenoma group[42.4％ (56/132),59.1％ (156/264)] were significantly higher than those of the normal control group (x2 =24.40,10.34,all P ＜ 0.05).The risk of population carrying the C allele suffering from nodular goiter was 2.086 times of those carrying the T allele (OR =2.086; 95％ CI:1.480-2.943).The risk of population carrying the C allele suffering from adenoma was 1.752 times of those carrying the T allele (OR =1.752,95％ CI:1.244-2.469).TRAIL + 1525 G/A:the genotypes and allele frequencies of nodular goiter group [40.4％ (55/136),62.9％ (171/272)] were significantly higher than those of normal control group [12.0％ (16/135),48.5％ (131/270); x2 =9.176,11.307,all P ＜ 0.05].The genotypes and allele frequencies of adenoma group[53.3％ (70/132),73.1％ (193/264)] were significantly higher than those of the normal control group (x2 =9.806,33.82,all P ＜ 0.05).The risk of population carrying the G allele suffering from nodular goiter was 1.796 times of those carrying the A allele (OR =1.796,95％ CI:1.275-2.531).The risk of population carrying the G allele suffering from adenoma was 2.884 times of those carrying the A allele (OR =2.884,95％ CI:2.009-4.142).Conclusions TGF-β1 + 869 T/C and TRAIL + 1525 G/A gene polymorphisms may be related to the incidence of nodular thyroid diseases; G allele of TRAIL and C allele of TGF-β1 may be predisposing genes of patients with nodular goiter.

Objective: To observe the co-effect of antioxidant compound, soybean isoflavone (SI), VC and VE on glucose and insulin response after oral glucose load in Type 2 Diabetes Mellitus (T2DM) . Methods: 96 selected T2DM patients (50% male, 50% female) were randomly divided into 4 groups according to the dosage of the compound given , none (group B), low dosage (group C), medium dosage (group D) and high dosage (group E) . The normal control (group A) included 24 persons half male, half female . Blood glucose and insulin were determined at OGTT 0 h, 1 h, 2 h, 4 h, 6 h, and the areas under the curve (AUC) of blood insulin/glucose were calculated. Results: The AUC of blood insulin/glucose of male was higher than female in control group, but both were lower than those of four diabetes groups. In both genders of the diabetes groups, blood insulin AUC of group C, D, E was lower than group B, blood glucose AUC of group D, E was lower than group C and B. There was significant difference in blood insulin and glucose AUC of group E as compared to group B in female (P

Background and Objectives: miR-450a-5p was involved in fat formation, however, its role in insulin resistance remains unclear. This study investigated the effects of miR-450a-5p on endothelial cells, with the aim of finding a potential target for diabetes mellitus. Methods: and Results: Human umbilical vein endothelial cells (HUVECs) were treated with low-glucose, high-glucose, methylglyoxal (MGO), and insulin alone or in combination with MGO. The expression of miR-450a-5p in treated cells was measured by quantitative real-time polymerase chain reaction (qRT-PCR) assays. The cell activity, migration and fat formation were determined by MTT experiments, Transwell assay and oil red O staining. The expressions of eNOS/ AKT pathway-related proteins in cells were assessed by Western blot (WB) analysis. Furthermore, the target gene of miR-450a-5p was analyzed by double-luciferase reporter analysis, and its effects on eNOS/AKT pathway were estimated. We found that the expression of miR-450a-5p was decreased obviously in endothelial cells treated with high-glucose and MGO. In vitro cell experiments showed that MGO could not only promote the activity of endothelial cells, but also accelerate cell migration and fat accumulation, which, however, could be reversed by up-regulation of miR-450a-5p. Moreover, MGO inhibited eNOS/AKT pathway activation and NO release mediated by insulin, and such effects were reversed by up-regulation of miR-450a-5p. Furthermore, CREB was the target gene for miR-450a-5p, had an activation effect on the eNOS/AKT pathway. Conclusions Up-regulated miR-450a-5p eliminates MGO-induced insulin resistance via targeting CREB, and therefore could be used as a potential target to improve insulin resistance and treat patients with diabetes-related diseases.

Objective To evaluate the efficacy,bleeding profile and safety of low-dose levonorgestrel-releasing intrauterine system (LNG-IUS 8) in Chinese healthy women of childbearing age.Methods A multi-center,open-label,single-arm clinical trial conducted at 16 centres in China enrolled 773 healthy women of childbearing age (mean age 31.6 years old,range 18 to 40 years old),who demanded contraception,from April 2006 to June 2013.All women placed LNG-IUS 8 for 3 years and then been followed up at 3,6,9,12,18,24,30,36 months.The efficacy variables including pregnancy rate and expulsion rate were analyzed using life table,while observing adverse events (AE) to evaluate the safety.The bleeding profile happened during the study was assessed using 90-day reference intervals (World Health Organization criteria).Results Eight pregnancies occurred among 773 women,resulting in a overall Pearl index of 0.42 per 100 women years.The 3-year cumulative pregnancy rate was 0.37 per 100 women years and the 3-year cumulative expulsion rate was 1.99 per 100 women years.The number of women with bleeding/spotting reduced and the bleeding/spotting days declined over time.Totally 219 AE were reported related to LNG-IUS 8 placements.The most common AE were vaginal bleeding (8.2％,63/773)and the ovarian cyst (6.2％,52/773).LNG-IUS 8 had an improving effect on dysmenorrhea that the percentage of women with dysmenorrhea as well as the days of dysmenorrhea decreased over time.The percentage of women satisfied or very satisfied with LNG-IUS 8 was 87.2％ (622/713).Conclusion LNG-IUS 8 is highly effective and safe for Chinese healthy women of childbearing age.
