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 high-risk factors of premenstrual acne to provide evidence for disease prevention and treatment.MethodsA total of 660 patients with premenstrual acne during February 2006 and October 2009 were retrospectively reviewed.Pillshbury method was used for diagnose and classification of premenstrual acne.Six hundred and sixty complete questionnaires were received for statistic analysis.Results Age and season showed no effect on moderate to sever premenstrual acne.However,spicy and fried food(x2=5.68),mental stress(x2=14.58),gastrointestinal disorders(x2=8.07),family history(x2=12.79),longer hairs around areolas(X2=11.88),and thyroid gland,adrenal gland or adnexal cysts(x2=9.72)had significantimpact on moderate to severpremenstrual acne(all P＜0.05).In addition.inflammatory papules on frontal partress were found in 67.4% of moderate premenstmal acne.ConclusionFood intake,mental health,gastrointestinal disorders,family history,longer hair around areolas,and thyroid gland,adrenal gland,adnexal cysts may be high-risk factors of premenstrual acne.

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.

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.

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.

Objective:To measure the voice samples of the normal aged in order to systemically study the fea-tures of the voice changes. Method :To collect and analyze 146 voice samples of the normal aged with sonogram.Result:The fundamental frequency of the voice of the aged decreases and rises in the male more than 80 yearsolder. The low frequency harmonics are regulation and the intensity is strong in the formant of the aged. Thedifference reduces in voice between male and female. The harmonics to noise ratio tends downwards and the am-plitude perturbation quotient tends upwards along with the growth of age in the aged male. The changes of the above-mentioned parameters are not significant in the aged female. Conclusion:The voice changes are normalphysiological ones in the normal aged. The changes of the parameters are used to evaluate normal aged voice andabnormal one. The changes show that the function in the aged phonation tends to decline to a certain extent andit must be protected and be trained.

Objective To monitor the distribution of pathogenic bacteria causing wound infection in trauma patients and their susceptibility to antibiotics in an effort to offer evidence for the rational clinical use of antibiotics.Methods Pathogens were identified by expressive type,but a very few was determined by the molecular methods.Micro-dilution or Kirby-Bauer method for minimum inhibitory concentration (MIC) was adopted for drug susceptibility test.Results A total of 121 species of pathogens numbering 1,257 bacterial strains were isolated from 1,066 patients.Strain number of the top 10 species accounted for 70.09％.Gram-positive cocci accounted for 48.93％ and Gram-negative bacilli for 49.72％.Among Staphylococcus aureus and epidermidis,methicillin-resistant bacterial strains accounted for 34.76％ and 71.08％ respectively,but none were resistant to vancomycin or linezolid.Enterococcus faecalis contained 6.06％ vancomycin-resistant enterococcal (VRE) and remained ＞ 90％ sensitive to teicoplanin,ampicilin and vancomycin.Enterococcus faecium contained 10.53％ VRE and remained ＞90％ sensitive to teicoplanin and ＞ 80％ sensitive to vancomycin.Baumanii contained 12.77％ multidrug resistant strains and remained ＞ 70％ sensitive to imipenem and meropenem.Baumanii/calcoaceticus complex contained 29.72％ multi-drug resistant strains and remained ＞ 50％ sensitive to imipenem and meropenem.Pseudomonas aeruginosa contained 3.73％ multi-drug resistant strains and remained ＞90％ sensitive to amikacin,meropenem,imipenem and piperacillin/tazobactam.No E.coli,klebsiella pneumoniae and enterobacter cloacae resistant to imipenem or meropenem were found.E.coli contained 69.51％ extended-spectrum β-lactamases (ESBLs)-producing strains and remained ＞ 90％ sensitive to piperacillin/tazobactam and ＞ 80％ sensitive to amikacin.Klebsiella pneumoniae contained 53.13％ ESBLs-producing strains and remained ＞ 80％ sensitive to amikacin.Conclusions Common bacteria are the leading cause of posttraumatic infection.Enterococcus faecalis and enterococcus faecium demonstrate higher susceptibility to teicoplanin; two kinds of acinetobacter demonstrate higher susceptibility to imipenem.
