AIM To compare high definition white light endoscopy and bright narrow band imaging for colon polyps' detection rates. METHODS Patients were randomised to high definition white light endoscopy(HD-WLE) or the bright narrow band imaging(b NBI) during withdrawal of the colonoscope. Polyps identified in either mode were characterised using b NBI with dual focus(b NBI-DF) according to the Sano's classification. The primary outcome was to compare adenoma detection rates(ADRs) between the two arms. The secondary outcome was to assess the negative predictive value(NPV) in differentiating adenomas from hyperplastic polyps for diminutive rectosigmoid *** A total of 1006 patients were randomised to HD-WLE(n = 511) or b NBI(n = 495). The mean of adenoma per patient was 1.62 and 1.84, respectively. The ADRs in b NBI and HD-WLE group were 37.4% and 39.3%, respectively. When adjusted for withdrawal time(OR = 1.19, 95%CI: 1.15-1.24, P < 0.001), the use of b NBI was associated with a reduced ADR(OR = 0.69, 95%CI: 0.52-0.92). Nine hundred and thirty three polyps(86%) in both arms were predicted with high confidence. The sensitivity(Sn), specificity(Sp), positive predictive value and NPV in differentiating adenomatous from non-adenomatous polyps of all sizes were 95.9%, 87.2%, 94.0% and 91.1% respectively. The NPV in differentiating an adenoma from hyperplastic polyp using b NBI-DF for diminutive rectal polyps was 91.0%.CONCLUSION ADRs did not differ between b NBI and HD-WLE, however HD-WLE had higher ADR after adjustment of withdrawal time. b NBI surpassed the PIVI threshold for diminutive polyps.

越冬成蚊的生理特征,是呈现生殖营养失调现象。意谓成蚊吸血的作用,不是供给卵巢发育之用,而是变成脂肪体储存在腹部。所以,凡是有蚊虫越冬的地区,均停止传代繁殖,而出现生活史中某一阶段的绝迹期。昆虫学家认为,针对这个蚊虫最弱的时期,进行杀灭工作,必收到良好效果。然而蚊虫有否越冬现象,是决定于冬季气候情况,冬季最冷的月平均气温在10℃以上地区,

背景去氧肾上腺素和麻黄素都可用于脊麻下剖宫声术中的血压维持。通常情况下单独给予其中一种，但也有关于两者联合应用的研究。然而，应用不同比例组合血管升压药的效果尚未见报道。方法125例产妇拟在脊麻下实施择期刮宫产手术，随机接受5种不同浓度比例的去氧肾上腺素和麻黄素复合静脉给药。假设100μg去氧肾上腺素约等效于8mg麻黄素，各组比例分别相当于100％、75％、50％、25％、0％的去氧肾上腺素和0％、25％、50％、75％、100％的麻黄素。调节输注速率以维持收缩压（SBP）在基线水平直到子宫切开。对血流动力学变化和脐带血气进行分析比较。结果随着各组去氧肾上腺素的比例下降和麻黄素比例的上升，我们发现下列显著趋势：低血压和恶心，口区吐的发生率增加，收缩压高于或低于基线差值的中位数俐数增加，收缩压高于基线的偏侈量增加，产妇心率增快，胎儿pH值和碱剩余降低，脐动脉血氧含量下降，脐静脉氧分压增加。结论脊麻剖宫产术中，当去氧肾上腺素和麻黄素以不同配比复合输注以维持血压时，随着去氧肾上腺素比例下降和麻黄素比例上升，血流动力学的可控性减弱，对胎儿酸碱平衔状况不利。对于防治剖宫产过程中的脊麻相关低血压，去氧肾上腺素和麻黄素复合输注与单独应用去氧肾上腺素相比似乎没有优势．
