Objective To analyze the difference in constituent and antimicrobial resistance of pathogens in commu-nity-associated urinary tract infection(CA-UTI)and healthcare-associated UTI(HA-UTI).Methods Clinical data and microbial detection of urine specimens of 960 patients with UTI in a hospital between January 2013 and June 2014 were investigated retrospectively,difference in constituent and antimicrobial resistance of pathogens were ana-lyzed.Results 403 cases were CA-UTI,and 557 were HA-UTI;pathogens in both CA-UTI and HA-UTI were gram-negative bacteria,accounting for 78.16% and 66.97% respectively.Constituent of pathogens in CA-UTI and HA-UTI were significantly different(χ2 =21 .68,P <0.001 ).Resistant rates of Escherichia coli to piperacillin /tazobactam,cefazolin,cefoperazone / sulbactam,aztreonam,meropenem,ertapenem,gentamicin,and compound sulfamethoxazole were all significantly different between CA-UTI and HA-UTI (all P <0.05);Except aztreonam, resistant rates of Escherichia coli in HA-UTI to the other antimicrobial agents were all higher than CA-UTI.Re-sistant rates of Enterococcus faecium in HA-UTI to penicillin,ampicillin,gentamicin,levofloxacin,ciprofloxacin, and moxifloxacin were all higher than CA-UTI(all P <0.05).Conclusion Constituent and antimicrobial resistance of pathogens in CA-UTI and HA-UTI are different,proper antimicrobial agents should be chosen according to con-stituent features of pathogens and change in antimicrobial resistance,so as to prevent and reduce the emergence of drug-resistant strains,and improve therapeutic effectiveness.

OBJECTIVETo evaluate the safety and effectiveness of GreenLight 120-W laser photoselective vaporization of the prostate (PVP) versus transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).

METHODSWe searched PubMed, Medline, Embase, Cochrane Library, Wanfang, CNKI, and VIP for randomized control trials and their references addressing 120-W PVP versus TURP in the treatment of BPH. Based on the inclusion and exclusion criteria, two reviewers independently accomplished the screening, quality assessment, and data extraction of the identified studies and performed meta-analyses using RevMan 5.2.

RESULTSTotally, 6 randomized control trials were included in this analysis, involving 703 cases, 351 treated by PVP and 352 by TURP. Compared with TURP, PVP showed significantly decreased time of catheterization (by 32. 55 hours, 95% CI 15.3 -49.8, P < 0.01), hospital stay (by 1.85 days, 95% CI 1.2-2.5, P < 0.01), and intraoperative blood loss (by 15.6 g/L, 95% CI 10.0-21.2, P < 0.01), but increased time of operation (by 9.37 minutes, 95% CI 5. 1-13.6, P < 0.01). There was also a significant reduction in blood transfusion, TUR syndrome, and capsular perforation in the PVP group. At 12 months after surgery, no statistically significant differences were found between the two groups in the improvement of maximum urinary flow rate, IPSS, postvoid residual, and sexual function.

CONCLUSIONGreenLight 120-W laser PVP is a safe and effective procedure for the treatment of BPH, with similar effectiveness to TURP but less blood loss, shorter time of catheterization and hospital stay, and lower incidences of blood transfusion, TUR syndrome and capsular perforation.

Sulfur fumigation (SF) is a universal phenomenon in primary processing of Traditional Chinese Medicine (TCM) in modern times. In the process, fumigation, sulfur or both of them act on the TCMs. Some active components of TCMs change quantitatively or qualitatively during the processing. At the same time, the sulfur dioxide and heavy metal would remain and cause a serious influence on quality and future development of TCM. This article reviews the chemical compositions change after SF to study the change law and their influence on quality. This article provide references for SF in TCMs' processing for a better and safer quality.

Infestation, moldy and other phenomenon in the processing and storage of Chinese herbal medicines is a problem that faced in the production of Chinese traditional medicine. The low productivity of traditional processing methods can not guarantee the quality of Chinese herbal medicines. Sulfur fumigation is the first choice of grassroots to process the Chinese herbal medicine with its low cost and easy operation. Sulfur fumigation can solve some problems in the processing and storage of Chinese herbal medicines, but modern pharmacological studies show that long-term use of Chinese traditional medicine which is fumigated by sulfur can cause some serious harm to human liver, kidney and other organs. This paper conducts a review about the application history of sulfur fumigation, its influence to the quality of Chinese herbal medicines as well as domestic and foreign limits to sulfur quantity, and a brief introduction of the status of modern processing technologies in the processing of food and some Chinese herbal medicines, the problems ex- isting in the Chinese herbal medicines processing, which can provide a reference basis for the further research, development and application of investigating alternative technologies of sulfur fumigation.

The glucagon-like peptide-1 (GLP-1) receptor agonist has been a well-received peptide product in the field of diabetes treatment .Semaglutide is a long-term GLP -1 agent, approved in December, 2017 by US Food and Drug Admins-tration(FDA).This article reviewed the pharmaceutical information , pharmacology and toxicology and clinical trial data of somaglutide , and commented on its efficacy and safety specially.We hope to provide reference for doctors and patients .

To explore the correlation between animal data that demonstra-ted potential thyroid C cells toxicity in non -clinical carcinogenicity stud-ies and clinical safety , in order to provide the basis for the non -clinical safety evaluation and clinical risks control .Summarized and untangled the carcinogenicity data and safety range of marketed drugs which could induce thyroid C cells tumors in non -clinical carcinogenicity studies , and analyszed the basis for approval .The correlation between animal thyroid C cells toxicity and human should be further studied .

Therapeutic mRNA vaccine for tumors attracted much attention as a new type of tumor treatment,and most products are in the preclinical and clinical research stage,and there has not post-market drug.However,the non-clinical evaluation of therapeutic mRNA vaccines for tumors is more complicated,due to their target features,mechanisms,delivery patterns,and the cross-species differences of immune system.The choice of animal model is not only content of the clinical effectiveness,and it was a key factor of toxicity assessment.In this work,the challenges for non-clinical evaluation of therapeutic mRNA vaccines for tumors are discussed,and the compliant requirements are reviewed,and the general considerations are suggested.

Objective To investigate the levels of serum Vitamin D(VD) from preconception to pregnancy in Jiading district of Shanghai, and explore the risk factors of VD concentration deficiency in the second and third trimester of pregnancy. Methods A total of 94 women who planned to have antenatal care and delivery in Maternal and Child Health Hospital of Jiading district of Shanghai from September 2016 to December 2018 were recruited as the study participants. Chemiluminescent immunoassay (CLIA) was used to examine the concentration of women’s serum VD from preconception to pregnancy. A total of 282 serum samples were detected. Results The prevalence of VD deficiency among 94 women from preconception to pregnancy were 40.4%,57.4% and 48.9% respectively. Results of the mixed linear model showed that women who had dyed or permed hair within the past 1 year had significantly lower serum VD levels during pregnancy (P<0.05), and women who often drank milk and ate deep-sea fish during pregnancy had higher VD levels during pregnancy (P<0.05). Conclusions VD deficiency was common among women in Jiading district of Shanghai, and it should be emphasized to supplement VD before and during pregnancy.
