| 1 | Heavy metal induced DNA changes in aquatic macrophytes: Random amplified polymorphic DNA analysis and identification of sequence characterized amplified region marker显示文摘Plants have been used as good bio-indicators and genetic toxicity of environmental pollution in recent years. In this study, aquatic plants Hydrilla verticillata and Ceratophyllum demersum treated with 10 μmol/L Cd, 5 μmol/L Hg, and 20 μmol/L Cu for 96 h, showed changes in chlorophyll, protein content, and in DNA profiles. The changes in DNA profiles included variation in band intensity, presence or absence of certain bands and even appearance of new bands. Genomic template stability test performed for the qualitative measurement of changes in randomly amplified polymorphic DNA (RAPD) profiles, showed significant effect at the given concentration of metals. Cloning and sequencing of bands suggested that these markers although may not be homologous to any known gene but its conversion as a sequence characterized amplified region (SCAR) marker is useful in detecting the effects of genotoxin agents. | Meetu Gupta Neera Bhalla Sarin | 2009 | Journal of Environmental Sciences2009，21，5： | 9 |

| 4 | Thiopurines are negatively associated with anthropometric parameters in pediatric Crohn's disease显示文摘AIM To determine the distribution of anthropometric parameter(AP)-z-scores and characterize associations between medications/serum biomarkers and AP-z-scores in pediatric Crohn's disease(CD).METHODS CD patients [< chronological age(CA) 21 years] were enrolled in a cross-sectional study. Descriptive statistics were generated for participants' demographic characteristics and key variables of interest. Paired t-tests were used to compare AP-z-scores calculated based on CA(CA z-scores) and bone age(BA)(BA z-scores) for interpretation of AP's. Linear regression was utilized to examine associations between medications and serum biomarkers with AP-z-scores calculated based on CA(n = 82) and BA(n = 49). We reported regression coefficients as well as their corresponding p-values and 95% confidence intervals.RESULTS Mean CA at the time of the study visit was 15.3 ± 3.5(SD; range = 4.8-20.7) years. Mean triceps skinfold(P = 0.039), subscapular skinfold(P = 0.002) and midarm circumference(MAC)(P = 0.001) BA z-scores were higher than corresponding CA z-scores. Medications were positively associated with subscapular skinfold [adalimumab(P = 0.018) and methotrexate(P = 0.027)] and BMI CA z-scores [adalimumab(P = 0.029)]. Azathioprine/6-mercaptopurine were negatively associated with MAC(P = 0.045), subscapular skinfold(P = 0.014), weight(P = 0.002) and BMI(P = 0.013) CA z-scores. ESR, CRP, and WBC count were negatively associated, while albumin and IGF-1 BA z-scores were positively associated, with specific AP z-scores(P < 0.05). Mean height CA z-scores were higher in females, not males, treated with infliximab(P = 0.038). Hemoglobin(P = 0.018) was positively associated, while platelets(P = 0.005), ESR(P = 0.003) and CRP(P = 0.039) were negatively associated with height CA z-scores in males, not females. CONCLUSION Our results suggest poor efficacy of thiopurines and a possible sex difference in statural growth response to infliximab in pediatric CD. Prospective longitudinal studies are required. | Neera Gupta Robert H Lustig Cewin Chao Eric Vittinghoff Howard Andrews Cheng-Shiun Leu | 2018 | World Journal of Gastroenterology2018，24，18： | 1 |

| 6 | High-dose infliximab for treatment of pediatric ulcerative colitis:A survey of clinical practice显示文摘AIM:To assess attitudes and trends regarding the use of high-dose infliximab among pediatric gastroenterologists for treatment of pediatric ulcerative colitis(UC).METHODS:A 19-item survey was distributed to subscribers of the pediatric gastroenterology(PEDSGI) listserv.Responses were submitted anonymously and results compiled in a secure website.RESULTS:A total of 113 subscribers(88% based in the United States) responded(101 pediatric gastroenterology attendings and 12 pediatric gastroenterology fellows).There were 46% in academic medical institutions and 39% in hospital-based practices.The majority(91%) were treating >10 patients with UC;13% were treating >100 patients with UC;91% had prescribed infliximab(IFX) 5 mg/kg for UC;72% had prescribed IFX 10 mg/kg for UC.Using a 5-point Likert scale,factors that influenced the decision not to increase IFX dosing in patients with UC included:'improvement on initial dose of IFX'(mean:3.88) and 'decision to move to colectomy'(3.69).Lowest mean Likert scores were:'lack of guidelines or literature regarding increased IFX dosing'(1.96) and 'insurance authorization or other insurance issues'(2.34).'Insurance authorization or other insurance issues' was identified by 39% as at least somewhat of a factor(Likert score ≥ 3) in their decision not to increase the IFX dose.IFX 10 mg/kg was more commonly used for the treatment of pediatric UC among responders based in the United States(75/100) compared to non-United States responders(6/13,P = 0.047).Induction of remission was reported by 78% of all responders and 81% reported maintenance of remission with IFX 10 mg/kg.One responder reported one death with IFX 10 mg/kg.CONCLUSION:IFX 10 mg/kg is more commonly used in the United States to treat pediatric UC.Efficacy and safety data are required to avoid insurance barriers for its use. | Roy Nattiv Janet M Wojcicki Elizabeth A Garnett Neera Gupta Melvin B Heyman | 2012 | World Journal of Gastroenterology2012，18，11： | 1 |
