当美国NPDES（全国污染排除计划）修订以后，许多地区将冷却水排污中的氯的最高质量分数降低至10^-9水平。以比色为基础的现有仪器，满足不了常规分析要求。最近开发了一种实验室用的自动电流滴定计，用于测定水中总氯，

AIM: To determine whether folic acid supplementation will reduce the recurrence of colorectal adenomas, the precursors of colorectal cancer, we performed a double-blind placebo-controlled trial in patients with adenomatous polyps. METHODS: In the current double-blind, placebo-controlled trial at this VA Medical Center, patients with colorectal adenomas were randomly assigned to receive either a daily 5 mg dose of folic acid or a matched identical placebo for 3 years. All polyps were removed at baseline colonoscopy and each patient had a follow up colonoscopy at 3 years. The primary endpoint was a reduction in the number of recurrent adenomas at 3 years. RESULTS: Of 137 subjects, who were eligible after confirmation of polyp histology and run-in period to conform compliance, 94 completed the study; 49 in folic acid group and 45 in placebo group. Recurrence of adenomas at 3-year was compared between the two groups. The mean number of recurrent polyps at 3-year was 0.36 (SD, 0.69) for folic acid treated patients compared to 0.82 (SD, 1.17) for placebo treated subjects, resulting in a 3-fold increase in polyp recurrence in the placebo group. Patients below 70 years of age and those with left-sided colonicadenomas or advanced adenomas responded better to folic acid supplementation. CONCLUSION: High dose folic acid supplementation is associated with a signif icant reduction in the recurrence of colonic adenomas suggesting that folic acid may be an effective chemopreventive agent for colorectal neoplasia.

AIM: To determine the role of interleukin (IL)-17 in gastric ulcerogenesis. METHODS: Thirty-six gastric ulcer (GU) patients and 29 non-ulcer (NU) patients were enrolled in this study. Mucosal biopsy samples were obtained from the gastric antrum and GU site during endoscopy. Samples were used in in situ stimulation for 48 h in the presence of 10 μg/mL phytohemagglutinin-P (PHA), histological examination, and Helicobacter pylori(H pylori) culture. IL-17 and IL-8 protein levels in culture supernatants were assayed by ELISA. IL-17 mRNA expression was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). H pylori cagA and vacA status was assessed by reverse hybridization using a line probe assay (LiPA). IL-8 levels in culture supernatants were assayed after AGS cells were co-cultured with H pylori strain 26 695 or recombinant human (rh) IL-17. RESULTS: All 36 GU patients and 15 of 29 NU patients were found to be H pylori-positive, while 14 NU patients were H pylori-negative. All 51 H pylori strains from both GU and NU patients were cagA- and vacAs1/m1-positive. Antral mucosal tissues from H pylori-positive patients contained significantly (H pylori-positive NU patients: median 467 pg/mg/protein, range 53-2 499; H pylori-negative NU patients: median 104 pg/mg/protein, range 16-312, P<0.0005) higher levels of IL-17 than those from uninfected patients. IL-17 levels at the ulcer site were significantly (ulcer site: median 1356 pg/mg/protein, range 121-1 3730; antrum: median 761 pg/mg/protein, range 24-7 620, P<0.005) higher than those at distant sites in the antrum. Biopsies from H pylori-positive GU and NU patients showed IL-17 mRNA expression in all samples whereas those from the antrum of the H pylori-negative controls showed no detectable expression. A significant correlation was seen between IL-17 and IL-8 levels at each biopsy site (ulcer: r= 0.62, P<0.0001; antrum: r = 0.61, P<0.0001) in GU patients. RhIL-17 and H pylori strain 26 695 each stimulated I

白化病是一种由于黑色素合成基因突变导致的眼、皮肤、毛发黑色素缺乏性遗传病,表现在眼部时患者虹膜、视网膜颜色浅淡或缺如,临床出现眼底着色不足、虹膜半透明、眼球震颤、高度屈光不正、视力低下等.白化病遍及全世界,总发病率为1/10 000～1/20 000,绝大多数的白化病患者并无智力或精神上的障碍[1-3].白化病眼球震颤在国内还没有手术治疗的先例,在国外也仅有Hertel教授的100例手术.我院与Hertle教授合作,于国内负责收集相关病例,于2012年4月20～29日邀请Hertle教授亲赴国内开展此项手术,手术顺利,并于10月底开始对手术患者进行术后复查,均取得了不同程度的疗效,现报道如下.
