Selenium, lycopene, alpha-tocopherol, beta-carotene, retinol, and subsequent bladder cancer

To examine the association between serum nutrients and the development of bladder cancer we measured selenium, alpha-tocopherol, lycopene, beta-carotene, retinol, and retinol-binding protein in serum collected from 25,802 persons in Washington County, MD, in 1974. Serum samples were kept frozen at -70 degrees C. In the subsequent 12-year period, 35 cases of bladder cancer developed among participants. Comparisons of serum levels in 1974 among cases and two matched controls for each case showed that selenium was significantly lower among cases than controls (P = 0.03), lycopene was lower among cases at a borderline level of significance (P = 0.07), and alpha-tocopherol was nonsignificantly lower (P = 0.13). For selenium there was a nearly linear increase in risk with decreasing serum levels (P = 0.03). When examined by tertiles, the odds ratio associated with the lowest tertile of selenium compared to the highest tertile was 2.06. Serum levels of retinol, retinol-binding protein, and beta-carotene were similar among cases and controls. These results support a role for selenium in the prevention of bladder cancer.     

Susceptibility of Ureaplasma urealyticum to Tetracycline,Doxycycline, Erythromycin,Roxithromycin, Clarithromycin,Azithromycin, Levofloxacin and Moxifloxacin

Abstract

The in vitro activity of tetracycline, doxycycline, erythromycin, roxithromycin, clarithromycin, azithromycin, levofloxacin and moxifloxacin was tested against 63 clinical isolates of Ureaplasma urealyticum. The minimal inhibitory concentrations (MICs) and the minimal bactericidal concentrations (MBCs) were determined by the broth microdilution method in A7 medium. The miC50 and miC90 of the tested agents after 24 h of incubation were as follows: Tetracycline, 0.5 and 2.0 μg/ml; doxycycline, 0.125 and 0.25 μg/ml; erythromycin, 2.0 and 8.0 μg/ml; roxithromycin, 2.0 and 4.0 μg/ml; clarithromycin, 0.25 and 1.0 μg/ml; azithromycin, 2.0 and 4.0 μg/ml; levofloxacin, 1.0 and 2.0 μg/ml; and moxifloxacin, 0.5 and 0.5 μg/ml, respectively. The MIC values after 24 h and 48 h incubation differed by no more than one dilution for all the agents with the exception of doxycycline (two dilution difference for MIC₉₀). Overall, moxifloxacin was the most active agent in vitro against U. Urealyticum, with the narrowest difference between MIC and MBC values, followed closely by levofloxacin. Clarithromycin was the most active macrolide.

80岁以上合并肠梗阻的结直肠癌患者的外科治疗

目的 探讨80岁以上合并肠梗阻的结直肠癌患者的外科治疗策略。方法 回顾性分析中国医学科学院结直肠外科2007年1月—2018年12月行结直肠癌手术且术前合并肠梗阻的77例80岁以上患者的临床病理资料,按照手术方式分为根治组（n=58）与非根治组（n=19）,比较两组患者临床病理特征、围手术期相关指标和预后。采用Kaplan-Meier法进行生存分析,Log rank检验进行生存时间比较;应用Cox比例风险模型进行多因素分析,对影响预后的因素进行分析。结果 根治组TNM分期为Ⅳ期患者的比例明显低于非根治组（8.6% vs. 57.9%, P<0.001）。根治组患者的5年生存率明显高于非根治组（65.5% vs. 26.3%, P<0.001）。单因素分析显示TNM分期和是否行根治性手术与合并肠梗阻的老年结直肠癌患者预后相关。多因素分析表明是否行根治性手术是影响80岁以上合并肠梗阻的结直肠癌患者预后的独立因素。结论 是否行根治性手术是影响80岁以上合并肠梗阻的结直肠癌患者预后的独立因素。
