Objective To investigate the distribution and evolvement of resistance profiles of the pathogens isolated from children diagnosed with urinary tract infection (UTI).Methods The pediatric patients who were diagnosed with UTI in Children's Hospital of Fudan University from January 2001 to December 2010 were enrolled in this retrospective study.The clean catch midstream urine samples were collected and the pathogens were isolated by culture.Bacterial susceptibility test was performed by following a protocol of the standardized Kirby Bauer (KB) method.The enumeration data were analyzed by chi square test and the tendency of drug resistant rate was analyzed by curvilinear regression.Results A total of 10 686 pathogen strains were isolated during the past 10years.The major pathogen was Escherichia coli which counted for 38％ -56％ of the isolates.However,the proportion of Enterococcus faecalis (0 - 17％,F =34.075,P =0.000) and Enterococcus faecium (3 ％ - 15 ％,F =7.139,P =0.028) increased rapidly.The resistant rates of Escherichia coli to cefazolin,cefuroxime sodium,cefotaxime and ceftazidime were 35.8％- 62.3％(F=215.735,P=0.000),33.1％ -57.0％(F=70.674,P=0.000),19.0％ -56.5％(F=52.355,P=0.000) and 2.1％-23.5％(F=16.807,P=0.003),respectively.The resistant rate of Escherichia coli to ciprofloxacin was 23.4％ - 33.8 ％ (F=0.989,P=0.349),while the resistant rate of Escherichia coli to amikacin and cefoperozone/sulbactam were both less than 7％.There was no Escherichia coli isolate showing resistant to imipenem.The resistant rates of Enterococcus faecium to ampicillin and ciprofloxacin were higher than 60.0％ and 50.0％,respectively,while the resistant rate of Enterococcus faecalis to these two antibiotics decreased from 40.0％ to 9.6 ％ (F =17.497,P =0.009) and 60.0％ to 21.6％ (F=12.826,P=0.009),respectively.The resistant rate of Enterococcus faecium to nitrofurantoin decreased from 32 ％ (in the year of 2002) to 9.4％ (in the year of 2010,F=34.075,P=0.000) and the resistant rate of Enterococcus faecalis decreased from 9.2％ (in the year of 2005) to 1.4％ (in the year of 2010,F=7.139,P=0.028).The resistant rates to erythromycin were both higher than 75.0％ in both Enterococcus in recent 10 years.There was no Enterococcus isolates showing resistant to vancomycin.Conclusions Escherichia coli,Enterococcus faecalis and Enterococcus faecium are the most common pathogens associated with UTI in children.The proportions of Enterococcus faecalis and Enterococcus faecium among the pathogens of UTI are increasing.The antimicrobial activity of ampicillin to Enterococcus faecalis keeps at a high level.However,there are few drugs can be used for treating Enterococcus faecium infection.

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.

Objective To assess the prevalence of Campylobacter in the children with acute bacterial diarrhea in Shanghai.Methods Epidemiological survey.Totally 6 641 children with acute bacterial infectious diarrhea from outpatients and inpatients in Children′s Hospital of Fudan University were submitted to the investigation during January 2011 to December 2012.The Campylobacter was isolated from stool samples collected from subjects in micro aerobic environment and identified by both multi-PCR and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry ( MALDI-TOF MS ) .Antimicrobial susceptibility tests were assayed by disk-diffusion method according to EUCAST standard.The isolates molecular typing was done by PFGE.SPSS16.0 was used to analyze the results.Results A total number of 6 641 subjects were enrolled, among them, 305 patients were infected with Campylobacter.The prevalence rate was 4.6%(305/6 641).Among the infected patients, 240 patients were infected with Campylobacter jejuni and 65 patients were infected with Campylobacter coli, the infectious rates of these two pathogenic bacteria were 3.6%and 1.0%, respectively.The peak infectious rate in patients older than 1 year of age was 6.2%(209/3 385) which was higher than that in children under 1 year of age (2.9%, 96/3 256),χ2 =35.98,P<0.001.The infectious rate in winter and spring (6.8%, 138/2 040) was higher than that in the other seasons ( 3.6%, 167/4 601 ) ,χ2 =28.59, P <0.001.Antimicrobial susceptibility test results showed that 91.5%( 279/305 ) isolates were resistant to ciprofloxacin and 11.8%( 36/305 ) isolates were resistant to erythromycin.A total of 9 genotypes of Campylobacter were found by PFGE cluster analysis.The similarity were ranged from 65.1%-100.0%for type A, 67.6%-100.0%for type B, 61.7%-100.0%for type C, 59.0%-100.0%for type D, 71.4%for type F, 80.0%for type H, 54.4%-90.9%for type I, and only one strain was classified as type E and G.Conclusions Campylobacter is a major pathogenic bacteria associated with acute bacterial infectious diarrhea in children especially in children older than 1 year of age in Shanghai.The prevalent pattern of this pathogen was sporadic and the sharp peak was in winter and spring.The isolates are highly resistant to ciprofloxacin but still sensitive to erythromycin.

ObjectiveTo investigate the effect of NGF on apoptosis of HSC in vitro and explore the possible mechanism.MethodsHSC was incubated with different concentrations of NGF.HSC apoptosis was identified by FCM.The expressions of apoptosis-regulating proteins Caspase-3,p53 and Bcl-2 of HSC after apoptosis induced by NGF were examined by immunohistochemical staining.Expressions of NGF and p75NTR were detected by immunofluorescence.ResultsApoptosis index of HSC was higher than that of control group [(22.36±9.51)％ vs (5.88±1.36)％] after treated with NGF (100 ng/ml) (P＜0.05).After incubating with 100 ng/ml NGF for 24 h,the positive expression rates of p53 and Caspase-3 of HSC increased significantly than those of control group [(78.41±4.00)％ vs (34.96±3.84)％,(39.26±1.57)％ vs (9.27±1.01)％,P ＜0.05].The positive expression rate of Bcl-2 protein of HSC significantly decreased compared with that of control group (18.12±1.38)％ vs (91.53±2.98)％ (P＜0.05).When HSC was stimulated with 100 ng/ml NGF for 24 h,the average optical density of NGF increased significantly than control group (6.53±1.40 vs 1.77±0.17) (P＜0.05),while the expression of p75NTR was not significantly changed (3.52±0.36 vs 4.24±0.38) (P＞0.05).ConclusionsThe mechanism of NGF to induce HSC apoptosis may be associated with the up-regulating expression of Caspase3,P53 and down-regulating expression of Bcl-2 on HSC.NGF could be used as an initiating factor and effect factor to increase the expression of NGF on HSC,but it had no significant effect on p75NTR expression.

OBJECTIVETo investigate the effect and its possible mechanism of interleukin-17 (IL-17) on invasion and metastasis of human colon cancer cells.

METHODSIL-17 was added into the culture media of human colon cancer cells SW480 and LOVO. Cells were divided into 4 groups: SW480 control group (SW480 cells), LOVO control group (LOVO cells), SW480 experiment group (50 μg/L IL-17+SW480 cells), and LOVO experiment group (50 μg/L IL-17+LOVO cells). Cell growth was measured by CCK-8 assay. The proliferation rate(%)=[(Aexperiment group-Ablank)/(Acontrol group-Ablank)]×100%). The ability of cell invasion and migration was measured by transwell assay. Real time-PCR was used to detect mRNA expression of VEGF and MMP-9. Western blot was performed to detect protein expression of STAT3, p-STAT3, VEGF and MMP-9. Enzyme-linked immunosorbent assay (ELISA) was applied to measure the protein content of VEGF and MMP-9 in the supernatant.

RESULTSAfter cultivation for 24, 48 and 72 hours, CCK-8 assay revealed that the proliferation rate of SW480 was 1.18%±0.07%, 1.42%±0.09%, and 1.62%±0.08%; the proliferation rate of LOVO was 1.13%±0.02%, 1.32%±0.05% and 1.73%±0.02% in experiment group. Transwell experiments showed that after cultivation with IL-17 for 24 hours, number of invasion cell in experimental groups (SW480: 34.00±0.45, LOVO: 41.60±0.51) was higher as compared to corresponding control groups (SW480: 4.53±0.14; LOVO: 3.67±0.33) with significant differences (SW480: t=-76.026, P=0.001; LOVO: t=-81.580, P=0.005). The number of migration cell in experimental groups (SW480: 36.40±0.51, LOVO: 46.40±0.68) was higher as compared to corresponding control groups (SW480: 7.83±0.69; LOVO: 6.67±0.48) with significant differences (SW480: t=-51.542, P=0.003; LOVO: t=-49.265, P=0.005). Real-time PCR results revealed that after cultivation with IL-17 for 24 hours, VEGF and MMP-9 mRNA relative expression levels in experimental groups (SW480: VEGF:1.53±0.12, MMP-9: 2.44±0.23; LOVO: VEGF: 2.96±0.35, MMP-9: 3.38±0.55) were higher than those in control groups (both 1) with significant differences (VEGF: t=3.799, P=0.043; MMP-9: t=5.254, P=0.039). Western blot illustrated that after cultivation with IL-17 for 24 hours, STAT3, p-STAT3, VEGF and MMP-9 proteins relative expression levels in experimental groups were significantly higher that those in control groups (SW480:STAT3: t=3.233, P=0.023; p-STAT3: t=3.954, P=0.032; VEGF: t=3.201, P=0.025; MMP-9: t=3.154, P=0.029; LOVO: STAT3: t=3.788, P=0.012; p-STAT3: t=2.662, P=0.040; VEGF: t=4.118, P=0.035; MMP-9: t=4.268, P=0.030). ELISA indicated that content of VEGF and MMP-9 in the supernatant of experimental groups (SW480: VEGF 5 491.41±63.22, MMP-9: 21.43±1.35. LOVO: VEGF: 8 631.46±129.59, MMP-9: 178.32±3.20) were higher than those in control groups (SW480: VEGF:4 456.32±87.56, MMP-9:18.57±2.44. LOVO: VEGF: 8 122.38±108.66, MMP-9: 163.22±6.89) with significant differences (SW480: VEGF: t=6.993, P=0.037; MMP-9: t=5.587, P=0.040. LOVO: VEGF: t=7.013, P=0.044; MMP-9: t=6.762, P=0.043).

CONCLUSIONIL-17 may be able to activate STAT3 signal transduction pathway in vitro through up-regulation of VEGF and MMP-9 expression, thereby enhancing the invasion and migration of colon cancer SW480 and LOVO cells.
