objective to study the correlation among psychosomatic health factors,depression,anxiety and sleep status in college students,to analyze influence factors in sleep status.methods with questionnaire opened in-vestigation,200college students were evaluated using cornell medical index,self-rating depression,self-rating anxiety scaleand pittsburgh sleep quality index.stepwise regression analysis was used.re-sults total score of sds was35.55±7.8,and sas was0.48±0.9.each score of cmi was higher than normal range,the highest was digestion system,next was respiration system,then,fatigue,eyes and ears,anxiety,sensitivity,tension,maladjustment in turn.total average score of psqi was6.32±3.6,ordinary sleep were115cases（57.5%）,good and bad sleep were42（21%）and43（21.5%）cases respectively.influence factors in total score of psqi were sas,cmi,respiration system,anxiety,past healthy,digestion system,fatigue,sensitivity,sds and malad-justment in turn,using stepwise regression analysis,total score of psqi as dependent variable,each factor score of cmi,total score of sds and sas as independent variables.conclusion problems of psychosomatic health,anxiety and depression could both lead to sleep disorder.

目的 研究在校大学生心身健康因素及抑郁焦虑等与睡眠状况的相关性，并对影响睡眠状况的有关因素进行分析。方法采用问卷式的开放性研究，对在校的200名大学生进行康奈尔心身健康问卷、自评抑郁量表、焦虑自评量表和匹兹堡睡眠质量量表的测定，采用逐步回归分析方法。结果 sds总分为35.55±7.8、sas总分为0.48±0.9，cmi评分：消化系统最为严重评分为2.52，其次为呼吸系统、疲劳感、眼和耳、焦虑、敏感、紧张、不适应等，评分均高于正常常模。psqi总均分为6.32±3.6，一般睡眠有115例占57.5%，睡眠质量较好42例占21.0%，睡眠质量较差43例占21.5%。评估对睡眠状况的影响程度，以psqi总分为因变量，选择cmi各因子分和sds、sas总分作为自变量，进行多因素逐步回归分析，进入方程的因素依据标准化偏回归系数，影响psqi总分的因素依次为sas总分、cmi总分、呼吸系统、焦虑、既往健康、消化系统、疲劳感、敏感、sds总分、不适应（f=226.8；p.01；r=0.73）。结论心身健康问题和焦虑抑郁可导致睡眠障碍。

The key to understanding this recipe lies in the definitions of the translate and maketrans functions in the string module. translate takes a string and replaces each character in it with the corresponding character in the translation table passed in as the second argument, deleting the characters specified in the third argument. maketrans is a utility routine that helps create the translation tables.

理解这一配方的关键，在于string模块中 translate 和 maketrans 函数的定义。translate接收一个字符串，并根据第二个参数中传入的转换表，将字符串中的每一个字符替换为相对应的字符，同时删除掉第三个参数中指定的字符（译者注：当translate作为字符串对象的方法调用时，转换表为第一个参数，第二个参数中指定要删除的字符）。maketrans 是一个用来帮助创建转换表的例程。

Methods Amplify the cDNA sequence encoding truncated HCV gene, with a part of carboxyl-terminus deleted, by PCR. Synthesize the mimic epitope at E2 region of HCV and seven T or Th cell epitope genes of NS3-NS5 respectively. Bind HCV core gene with a part of carboxyl-terminus deleted to the synthetic epitope gene by PCR, then clone into eukaryotic expression vector pcDNA3.1 and transiently transfect COS7 cells.

用PCR方法扩增核心区羧基端部分缺失的基因片段；分别合成HCV E2区模拟表位和NS3~NS5 7个T或Th细胞表位基因；PCR方法将羧基端部分缺失的HCV核心区基因与合成的表位基因串联，克隆入真核表达载体pcDNA3.1，并通过脂质体瞬时转染COS7细胞。
