Objective To understand the drug resistance status of extended-spectrum beta-lactamase(ESBLs)-producing Esche-richia coli (E.coli)and Klebsiella pneumonia (KPN ),and the prevalence situation of TEM and SHV genotype in Wusu city.Meth-ods E.coli and KPN isolated in two hospitals of Wusu city from July 2011 to June 2013 were collected and the drug sensitivity test was performed by the disk diffusion method (K-B method),the ESBLs preliminary screening and the phenotypic confirmatory test were carried according to the guideline of CLSI,and at the same time DNA of ESBLs producing strains was extracted and the TEM and SHV genes among them were tested by PCR and the electrophoresis method.Results Totally 221 strains of E.coli and 153 strains of KPN were collected,among them ESBLs producing strains were 37 strains and 43 strains respectively,and the detec-tion rate of ESBLs in KPN was higher than that in E.coli(χ2 =6.942,P <0.01).The drug resistance of two kinds of bacteria were similar,the resistance rate of ESBLs producing strains to beta lactam antibacterial drugs was obviously higher than that in non-en-zyme producing strains,which was mostly more than 90%;the resistance rate to penicillin and the first or second generation cepha-losporins was almost 100%;which to gentamicin and ciprofloxacin was above 50%;while which to carbapenem was lower,less than 5%.The detection rates of TEM and SHV genes were 72.9% and 54% in ESBLs producing E.coli and 81.4% and 65.1% in KPN respectively,the detection rates were basically consistent without statistically significant differences between them (P >0.05).Conclusion The detection rate of ESBLs producing E.coli and KPN in Wusu city is higher,the drug resistance situation is severe,and TEM,SHV are the important genotypes of ESBLs.

Objective To investigate the effect of AlkB homologue 5 ( ALKBH5 ) on proliferation, cell cycle, and apoptosis of HepG2 and L-02 cells.Methods Recombinant plasmid vector containing the CDS region of ALKBH5 (pEGFP-C1b-ALKBH5) was stably transfected into HepG2 and L-02 cells.Western blotting was used to detect the expression of green fluonescence protein ( GFP )-ALKBH5.There were two groups in our experiment: GFP-ALKBH5 lentivirus group and GFP lentivirus group.Characteristics, such as proliferation, cell cycle and apoptosis of HepG2 and L-02,were detected through Cell Counting Kit-8 (CCK-8) assay, flow cytometry and clone formation, respectively.Results The result of Western blotting revealed that ALKBH5 was efficiently up-regulated at protein levels.Despite apoptosis, phenotypic analysis revealed that the proliferation and cell phases were significantly inhibited in ALKBH5 overexpressed stable cell strains compared with the control cells (both P<0.05).Conclusion ALKBH5 can restrain fetal liver cell (L-02) and hepatocellular carcinoma cell (HepG2) from proliferating.Taken together, our results strongly suggest that ALKBH5 can play a key role in the generation and progression in HCC as a tumor suppressor.

Objective To study the genetic susceptibility in patients with postpartum thyroiditis(PPT)by genotyping their human leukocyte antigen(HLA)-DP and -DQ alleles.Methods The polymerase chain reaction-sequence based typing(PCR-SBP)method was used to analyze the distribution of HLA-DPA1,HLA-DPB1,HLA-DQA1 and HLA-DQB1 alleles among 52 PPT patients(31 clinical patients,21 subclinical patients)and 82 healthy controls.Compare the allele frequencies between various patient groups and the control population.Results There was no significant difference between patient group and control group.Conclusion Perhaps PPT is not associated with HLA-DP and HLA-DQ alleles.

Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the People's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.

The first metatarsophalangeal joint bending plays an important role in the foot movement. However, the existing researches mainly focused on the movement scope of the joint and the clinical treatments of related foot diseases. In order to investigate the effects of the first metatarsophalangeal joint bending on human walking gait stability, the present researchers recruited 6 healthy young men to perform the first metatarsophalangeal joint constraint (FMJC) and barefoot (BF) walking tests. Data of the temporal and spatial parameters, the joint angles of lower limbs, the ground reaction forces (GRF) and utilized coefficients of friction (UCOF) were collected and analyzed. The results showed that, since hip and knee could produce compensation motions, the FMJC had no significant effects on waking gait, but the slip and fall probability increased significantly.
