为了优选烧烤牛肚的制作工艺条件,本实验以市售新鲜牛肚为研究对象,选取嫩度、颜色、多汁性、风味、弹性和润滑性为评价指标,确定各指标的合理权重,建立模糊综合评价体系,以得到各样品的综合评分,进一步采用4因素3水平的Box-Behnken响应面分析法,优化烧烤牛肚的制作工艺条件。结果显示,基于模糊数学感官评价法优化烧烤牛肚的最优制作条件为水煮时间8.00 min,泡椒比例18.22%,泡制时间4.50 h,烧烤时间6.20 min。在此条件下得到的烧烤牛肚颜色鲜亮,香味浓郁,口感细腻、脆嫩,烧烤牛肚综合得分为47.61±2.10。表明模糊数学和响应面法相结合用于烧烤牛肚工艺优化切实可行,且重复性较好。

经自然腔道取标本手术(NOSES)通过无切口理念与常规手术器械的结合,表现出极佳的微创效果,并带给患者全新的就医感受.目前,尽管NOSES已广泛用于结直肠肿瘤治疗,大量研究也表明相比常规腹腔镜手术,NOSES具有恢复快、创伤小、疼痛轻等优势,但绝大多数研究均为小样本、单中心回顾性研究.本研究旨在通过分析我国5055例结直肠肿瘤NOSES患者数据,进一步探讨NOSES的短期疗效与预后.研究对象中,经直肠NOSES占整体比例的90.3%,经阴道NOSES占9.7%.NOSES术后短期并发症发生率为14.1%,吻合口瘘发生率为4.9%,腹盆腔感染率为1.9%.患者3年总生存率为93.2%,无病生存率为82.2%,局部复发率为3.6%.研究结果提示NOSES具有较好的安全性与可行性,为其应用于结直肠肿瘤治疗提供了证据.

为了探究不同物理防治方法对麦田内麦蚜天敌及小麦生长的影响,2011~2012年设空白对照(CK)、黄板、糖醋液、诱芯、灯诱和综防6个麦蚜防治方法处理,观察了麦蚜天敌种群动态以及小麦农艺性状和产量的变化。结果表明:与CK相比,5种物理防治方法均造成小麦田内瓢虫和蚜茧蜂的种群数量降低,但不同年份间数据差异具有不稳定性,其中,2011年各物理防治方法处理的指标值与CK差异均达到了显著水平,而2012年这种差异均不显著;除黄板处理外,灯诱、诱芯、糖醋液以及综防处理对小麦株高和穗长均无显著影响。不同物理防治方法处理均能显著提高小麦产量,其中,综防处理效果最佳。
