简介：“尴尬、高冷、颓势”，是近些年描述威尼斯电影节最多的三个标签。在欧洲三大电影节中，柏林开幕早，占了可以提前挑选片子的先机；戛纳大师云集，片子水准高；以卖片为目的的多伦多影展又虎视眈眈地在威尼斯尚未闭幕时开幕，所有这些，成了威尼斯地位尴尬的佐证。前年的金狮《罗马环城高速》和去年的金狮《寒枝雀静》都是纯粹的艺术片，这种艺术至上的选片口味被斥为高冷。

简介：摘要目的对小儿腹泻患儿采用思密达联合金双歧治疗，对其临床治疗效果进行分析。方法自我院2013年4月~2014年4月儿科收治的小儿腹泻患儿中选取72例为研究对象，将其随机分为观察组和对照组，两组患儿各36例，均给予常规治疗，并给予口服思密达，观察组在此基础上联合金双歧进行治疗，对两组患儿临床治疗效果进行对比。结果观察组患儿临床治疗有效率和对照组患儿临床治疗有效率分别为94.4%和75.0%，观察组患儿临床治疗有效率高于对照组，数据对比有统计学意义（P＜0.05）。观察组患儿治疗后止泻时间、退热时间、腹痛消失时间及大便常规正常时间均优于对照组，数据对比有明显差异（P＜0.05），有统计学意义。结论在对小儿腹泻患儿实施治疗的过程中，思密达联合金双歧的应用能够提高临床治疗效果，缩短治疗时间，使患儿尽快恢复健康，具有显著效果。
