英语写作一直是大学英语教学的薄弱环节。因此,如何提高英语应用文写作能力对高职高专院校的学生而言尤为重要。本次调查分析以问卷形式了解针对高职高专学生实施活动教学策略对英语写作课程的辅助情况,为进一步制定科学合理的英语应用文写作教学方法提供依据。     

高等数学教学中差分方程的经济学拓展

经济管理类学生有其自身的专业特点,在高等数学教学中也应体现出不同的特色.通过讨论差分方程在银行信贷、国民经济增长等方面的重要应用,可以使学生加深对差分方程概念和求解方法的理解,并培养学生利用数学思想解决经济问题的思维能力,从而达到经济管理类院校数学教师将数学与经济学有机结合的教改目的.     

西藏中学生家庭环境与问题行为的关系研究--以藏族中学生为例

Methylenetetrahydrofolate reductase C677T polymorphism predicts response and time to progression to gemcitabine-based chemotherapy for advanced non-small cell lung cancer in a Chinese Han population

Objective:The aim of this study was to evaluate the association between the methylenetetrahydrofolate reductase(MTHFR) C677T excision repair cross-complementation group 1(ERCC1) genetic polymorphisms and the clinical efficacy of gemcitabine-based chemotherapy in advanced non-small cell lung cancer(NSCLC).Methods:A total of 135 chemonaive patients with unresectable advanced NSCLC were treated with gemcitabine/platinum regimens.The polymorphisms of MTHFR C677T,ERCC1 C8092A,and ERCC1 C118T were genotyped using the TaqMan methods.Results:The overall response rate was 28.9%.Patients with MTHFR CC genotype had a higher rate of objective response than patients with variant genotype(TT or CT)(41.2% versus 19.1%,P=0.01).Median time to progression(TTP) of patients with MTHFR CC genotype was longer than that of patients with variant genotype(7.6 months versus 5.0 months,P=0.003).No significant associations were obtained between ERCC1 C118T and C8092A polymorphisms and both response and survival.Conclusions:Our data suggest the value of MTHFR C677T polymorphism as a possible predictive marker of response and TTP in advanced NSCLC patients treated with gemcitabine/platinum.
