Objective: To study the mechanism of baicalin in inhibiting Mycobacterium tuberculosis（MTB）and to provide reference for drug-resistant tuberculosis treatment. Methods: Forty male Kunming mice were injected isoniazid-resistant MTB into their tail veins to build models of infection. They were evenly divided into MTB group,isophosiazone group,NF-κB inhibition group and baicalicin group according to treatment. The lung tissue and peripheral blood of the mice were collected on the 8th day after modeling. The morphological changes of the lungs were observed by HE staining. The number of MTB in lung tissue was detected by acid-fast staining and quantitative PCR. The number of macrophagein lung tissue was detected by immunohistochemistry. The expression of NF-κB and TLR4 in monocytes/macrophages were detected by flow cytometry. Results: The average weight of mice in the baicalicin group was significantly higher than that in the MTB group,the isophosiazone group and the NF-κBinhibition group（P<0.05）. The average fluorescence intensity of NF-κB and TLR4 in monocytes/macrophages in the baicalicin group were 448.21±30.61 and 401.01±34.58,which were significantly higher than those in the MTB group and the isophosiazone group（P<0.05）. Typical tuberculous chronic granulomatous lesions were observed in the MTB group,isophosiazone group and NF-κB inhibition group,except the baicalin group. The mean number of MTB and CD68+ macrophagesin lung tissue of mice in the baicalin group were significantly less than that in the MTB group,the isophosiazone group and the NF-κB inhibition group（P<0.05）. Conclusion Baicalin achieves an anti-tuberculosis effect by regulating the expression of NF-κB and TLR4 in macrophages,which can be weakened by adding NF-κB inhibitor.

Objective To investigate the molecular epidemiology and antimicrobial resistance status of uropathogenic Escherichia coli (UPEC) in senior population in Putuo District ,Shanghai .Methods A total of 72 UPEC strains were isolated from elderly inpatients with urinary tract infections in Putuo Hospital ,Shanghai University of Traditional Chinese Medicine from January 2013 to March 2015 .The strains were characterized by multi‐locus sequence typing (MLST ) .The β‐lactamase gene and the plasmid mediated quinolone resistance (PMQR) gene were detected ,and the mutations of quinolone resistance‐determining regions (QRDR) in gyrA and parC genes were demonstrated .In vitro drug susceptibility test was performed .Continuous variables were compared using t test and categorical variables were compared using chi‐squared test or Fisher exact test .Results The UPEC strains showed different resistance rates to ciprofloxacin ,cefotaxime and trimethoprim‐sulfamethoxazole ,which were 76 .4% ,73 .6% and 65 .3% , respectively .UPEC still remained highly sensitive to imipenem ,meropenem ,amikacin and piperacillin‐tazobactam .Among 72 isolates ,55 (76 .4% ) of 49 (68 .1% ) extended‐spectrum β‐lactamase (ESBL )‐positive strains harbored blaCTX‐M genes .Among the 55 ciprofloxacin resistant strains ,51 (92 .7% ) had three or four mutations in QRDR of gyrA and parC genes .The “hot‐spot” mutations of QRDR were located at amino acid position 83 and 87 in gyrA gene and at positions 80 and 84 in parC gene .Forward analysis by MLST showed that the most frequent sequence types (ST ) were ST131 (18/72 ,25 .0% ) , ST1193(7/72 ,9 .7% ) ,ST405 (7/72 ,9 .7% ) ,ST38 (5/72 ,6 .9% ) and ST648 (3/72 ,4 .2% ) .ST131 isolates were predominant in ST which caused community‐onset urinary tract infections .Multiple drug‐resistance were detected in ST 131 ,ST405 ,ST38 and ST648 which were mainly producing blaCTX‐M ESBL .Conclusions Community‐acquired multiple drug‐resistant UPEC strains such as ST131 clone are prevalent in elderly patients .Thus ,monitoring of molecular epidemiology would be beneficial to prevent the prevalence of multiple drug‐resistant UPEC .

Objective: To explore the characteristics of psychological control of parents of college students and their correlation with health risk behaviors, and to provide a reference for further improving parenting styles and improving the physical and mental health of college students. Methods: With the method of multi-stage stratified random sampling, 3 318 college students from 6 universities in Guizhou Province were selected. The parents’ psychological control questionnaire and Chinese adolescent health-related behavior questionnaire were used to conduct anonymous field survey. Results: A total of 660 students’ parents have got low score of mental control in low-score group (<26), 1 844 in the middle group (26-49) and 814 in the high group (>49). Students who had suicide plans scored higher in the dimensions of invasion of privacy, inhibition of speech expression, and sense of disability than those who had not(t=4.08, 3.74, 3.82, P<0.01); The scores of smokers in achievement expectation, invasion of privacy and ability ineffectiveness were higher than those of non-smokers(t=7.12, 3.91, 8.10, P<0.01); the scores of drinkers in all dimensions were higher than those of non drinkers(t=9.35, 4.64, 5.90, 8.78, P<0.01); the scores of Internet addicts in all dimensions were higher than those of non-smokers(t=8.92, 14.27, 3.70, 15.94, P<0.01). Spearman correlation analysis showed that smoking, drinking and Internet addiction were positively correlated with parents’ psychological control(r=0.11, 0.15, 0.19, P<0.01). Conclusion Parents’ psychological control of college students in achievement expectation, ability ineffectiveness and speech inhibition; parents’ psychological control is positively related to smoking, drinking and Internet addiction behavior. Parents should give more active encouragement and guidance to their children and strengthen communication.
