| 1 | Resistance of Helicobacter pylori to furazolidone and levofloxacin: A viewpoint显示文摘In their review, Arslan et al[1] did not describe the status of Helicobacter pylori(H. pylori) treatment with furazolidone and the resistance to this antibiotic. We have presented different surveys showing the resistance of H. pylori to furazolidone from Asia and South America. The resistance rates varied but were mostly low(< 5%). There are not enough data on its efficacy and resistance in the United States and Europe. H. pylori mutations occurring in the oor D gene, including A041 G, A122 G, C349A(G), A78 G, A112 G, A335 G, C156 T and C165 T, and in the por D gene, including G353 A, A356 G, C357 T, C347 T, C347 G and C346 A, have been indicated to be possibly related to the observed resistance. Additionally, to complete Arslan et al 's statement regarding levofloxacin resistance, it should be noted that compound mutations of N87 A, A88 N and V65 I at codon Asn-87 were recently observed in the gyr A gene for the first time. However, the results on these topics are not sufficient, and more worldwide studies are suggested. | Mohammad Zamani Arash Rahbar Javad Shokri-Shirvani | 2017 | World Journal of Gastroenterology2017，23，37： | 10 |

| 6 | Hypoallergenic formula with Lactobacillus rhamnosus GGfor babies with colic:A pilot study of recruitment,retention,and fecal biomarkers显示文摘AIM To investigate recruitment, retention, and estimatesfor effects of formula supplementation withLactobacillus rhamnosus GG (LGG) on inflammatorybiomarkers and fecal microbial community in infants withcolic.METHODS: A prospective, double-blind, placebocontrolledtrial was conducted in otherwise healthyinfants with colic. We screened 74 infants and randomizedand analyzed results in 20 infants [9 receivingLGG (LGG+) and 11 not receiving LGG (LGG-)]. LGG wasincorporated in the formula (Nutramigen?) (minimum of3 × 10^7 CFU/d) in the LGG+ group. Fecal microbiota andinflammatory biomarkers, including fecal calprotectin(FC), plasma cytokines, circulating regulatory T cells(Tregs), and crying + fussing time were analyzed todetermine optimal time points and effect sizes for alarger trial.RESULTS: Recruitment in this population was slow, withabout 66% of eligible infants willing to enroll; subjectretention was better (75%). These rates were influencedby parents' reluctance to volunteer their infant for aclinical trial and by their tendency to change formulas.The maximal difference of crying + fussing time wasobserved at day 14, comparing the 2 groups, with amean difference of -91 (95%CI: -76, 259) min (P = NS).FC showed no significant difference, but the optimaltime to determine a potential effect was at day 90 [witha mean difference of 121 (95%CI: -48, 291) μg/g stool],observing a lower level of FC in the LGG+ group. Thefecal microbial communities were chaotic, as determinedby Shannon's diversity index and not apparently influencedby the probiotic. No significant change wasobserved in plasma inflammatory cytokines or Tregs,comparing LGG+ to LGG- groups.CONCLUSION: Designing future colic trials involving aprobiotic-supplemented formula for infants in the UnitedStates will require consideration for difficult enrollment.Infants with colic have major variations in feal microbiotaand calprotectin, both of which improve with time, withoptimal time points for measurement at days 14 and 90after treatment. | Nicole Y Fatheree Yuying Liu Michael Ferris Melissa Van Arsdall Valarie McMurtry Marcela Zozaya Chunyan Cai Mohammad H Rahbar Manouchehr Hessabi Ta Vu Christine Wong Juleen Min Dat Q Tran Fernando Navarro Wallace Gleason Sara Gonzalez J Marc Rhoads | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，1： | 1 |

| 8 | Survey of epidemiology and bacteriology features of cholera in Iran显示文摘Objective:To determine epidemiology and antimicrobial susceptibility patterns of Vibrio(V.) cholerae O1 biotype EL Tor in summer outbreak of 2008 in Iran.Methods:Stool samples were collected from patients suspected to have cholera admitted to hospitals and clinics.Specimens examined by conventional bacteriological methods.All isolates were sent to cholera reference laboratory for further confirmation,stereotyping and susceptibility testing.Results:A total of 220 patients were diagnosed as cholera.All cases confirmed by Iranian reference health laboratory.One hundred ninety nine of 220 V.cholerae serotypes were Inaba and 21 serotypes were Ogawa.All cases were reported from thirteen provinces.The majorities of cases were from Tehran,Qum and Zahedan provinces with 56,26 and 25 cases respectively.24(11%) of patients were under 15 years old and 196(89%) of patients were older than 15 years.149(68%) of patients were male and 71(32 %) were female.129(59%) of patients had Iranian nationality,79(36.5%) were from Afghanistan and,12(5%) were from Pakistan.All isolates were resistant to co-trimoxazole,nalidixic acid,furazolidone,and intermediate to chloramphenicol and were susceptible to tetracycline, ciprofloxacin,and erythromycin.Conclusion:Our study reveals that in recent outbreak caused by V.cholerae EL Tor serotype Inaba is the predominant serotype.All isolates are resistant to cotrimoxazole. nalidix acid and furazolidon. | Mohammad Rahbar Mohsen Zahraei Aboulgasm Omidvarnia Mohammad Taqi Afshani Mostafa Glami Rogaeieh Sabourian Shahla Farsi Hosein gholami Saeid Mahdavi Parisa Islami Mona Mohammad Zadeh Massoud Hajia Azar Valipour Rana Amini | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，1： | 0 |
| 9 | Burden of nonalcoholic fatty liver disease and advanced fibrosis in a Texas Hispanic community cohort显示文摘AIM: To investigate the potential burden of nonalcoholic steatohepatitis(NASH) and advanced fibrosis in a hispanic community.METHODS: Four hundred and forty two participants with available ultrasonography data from the Cameron County Hispanic Cohort were included in this study. Each participant completed a comprehensive questionnaire regarding basic demographic information, medical history, medication use, and social and family history including alcohol use. Values of the nonalcoholic fatty liver disease fibrosis score(NFS), FIB4 index, BARD score, and Aspartate aminotransferase to Platelet Ratio Index(APRI) were computed using the blood samples collected within 6 mo of liver ultrasonography from each participant. Hepatic steatosis was determined by ultrasonography. As part of univariable analysis, for continuous variables, comparisons among groups were performed with student-t test, one way analysis of variance, and Mann-Whitney test. Pearson χ2 and the Fisher exact test are used to assess differences in categorical variables. For multivariable analyses, logistic regression analyses were performed to identify characteristics associated with hepatic steatosis. All reported P values are based two-sided tests, and a P value of less than 0.05 was considered to indicate statistical significance.RESULTS: The mean age and body mass index(BMI) of the study participants were 49.1 years and 31.3 kg/m2, respectively. Among them, 65.6% were females, 52% had hepatic steatosis, 49.5% had metabolic syndrome, and 29% had elevated aminotransferases. Based on established cut-offs for diagnostic panels, between 17%-63% of the entire cohort was predicted to have NASH with indeterminate or advanced fibrosis. Participants with hepatic steatosis had significantly higher BMI(32.9 ± 5.6 kg/m2 vs 29.6 ± 6.1 kg/m2, P < 0.001) and higher prevalence rates of elevation of ALT(42.2% vs 14.6%, P < 0.001), elevation of aspartate aminotransferase(38.7% vs 18.9%, P < 0.001), and metabolic syndrome(64.8% vs 33%, P < 0.001) than those without hepatic steatosis. The NFS scores(P = 0.002) and the APRI scores(P = 0.002) were significantly higher in those with steatosis but the scores of the FIB4 index and BARD were similar between the two groups. After adjusting for age, gender and BMI, elevated transaminases, metabolic syndrome and its components, intermediate NFS and APRI scores were associated hepatic steatosis in multivariable analysis. CONCLUSION: The burden of NASH and advanced fibrosis in the Hispanic community in South Texas may be more substantial than predicted from referral clinic studies. | Jen-Jung Pan Susan P Fisher-Hoch Chaoru Chen Ariel E Feldstein Joseph B Mc Cormick Mohammad H Rahbar Laura Beretta Michael B Fallon | 2015 | World Journal of Hepatology2015，7，11： | 0 |
