Objective To investigate the distribution of carbapenem-resistant genes and their drug susceptibility in vitro on carbapen-em-resistant Enterobacter cloacae(CRECC)in Taizhou area,and provide evidence for effective anti-infective treatment in clinical prac-tice.Methods Forty-seven strains of CRECC isolated from Enze Hospital,Taizhou Enze Medical Center(Group)and Luqiao Reha-bilitation Hospital during January 2015 and November 2022 were retrospectively analyzed.The enzyme types and resistance genes of carbapenemase were detected by the NG-Test Carba 5 and Carba-R Xpert,respectively,and the susceptibility of CERCC to common drugs was tested in vitro.Results Among 47 strains of CRECC,27 were detected to produce carbapenemase,including 24 producing New Delhi metallo-β-lactamase(NDM)type,1 producing both Klebsiella pneumoniae carbapenemase(KPC)and NDM types,and 2 producing imipenemase(IMP)type.One strain belonged to NDM genotype but no NDM enzyme type was detected.The CRECC strains had the highest sensitivity to polymyxin B(95.7%),followed by tigecycline(93.6%),fosfomycin(61.7%),and ceftazidime/avibac-tam(40.4%).In addition,the CRECC strains producing carbapenemase were more sensitive to polymyxin B,fosfomycin and aztreo-nam than those without producing carbapenemase.Conclusion The CRECC strains in Taizhou area are mainly NDM type,which has high sensitivity to polycolistin B,tigecycline and fosfomycin.NG-Test Carba 5 can not cover some strains that do not produce carbapen-emase or carry mutations in carbapenemase.

Bioelectrical impedance analysis(BIA)measures the body composition and its change by the electric feature of the extracellular fluid and intracellular fluid.It has been widely used for its noninvasiveness, convenience and accuracy, especially in population epidemiology and clinical monitoring.We aim to review the advantages and shortcomings,and try to discuss about the application of this technique and its potential.

To study the protective effects of salidroside on oxidative damage in fatigue mice.

ificantly lower than in both middle and low group(P＜0.05).Conclusion TP may improve the antioxidant ability of experimental aging mice.

the effect of maintaining integrity of epithelial cells by increasing occludin protein expression,and the effect is related with the up-regulation of occludin mRNA.

Objective To evaluate the promote effect of Danisco products Bifidobacterium Lactis Bi07 & Lactobacillus acidophilus NCFM on physical intestinal canal microbial eco-system.Methods A 3-week randomized trial was conducted in 400 healthy persons aged from 25 to 45 years,with a male to female ratio of 1∶1,they were randomly divided into 2 groups: placebo group and probiotics group.Each group takes the corresponding products 100 g twice everyday at 10 a.m.and 4 p.m respectively.Results Digestive system on microbial eco-system was effectively improved.The viable count of Bifidobacteria and Lactobacillus was significantly increased.The viable count of Clostridiumperfringen was significantly decreased.Conclusions Significant effectiveness on physical intestinal canal microbial ecosystem were proved by intake Danisco probiotics products 200 g per day for 21 days.

myocytes.In aging mice induced by D-galactose experiment.TP has anti-apoptosis and anti-oxidation effect in a dose-dependant manner.
