鼻咽癌茎突后间隙侵犯的临床意义探讨

目的 探讨鼻咽癌茎突后间隙侵犯的临床意义。方法 １９９２年１２月～１９９３年１２月１９８Ⅰ－Ⅳａ期鼻咽癌住院初治患者接受受根治性放射治疗。按茎突后间隙有无侵犯分为茎后侵犯组和茎后无侵犯组。应用Ｋａｐｌａｎ－Ｍｅｉｅｒ,Ｌｏｇ－Ｒａｎｋ及卡方检验等方法对两组患者５年生存率、局部控制率和无远处转移生存率进行分析和评价。结果两组患者口咽侵犯率分别为７２．１％和１６．８％（Ｐ〈０．００１）,后组颅神经侵犯     

Urban-rural comparison of HBV and HCV infection prevalence in eastern China

The present study was initiated to make and urban-rural comparison of the prevalence of cases positive to hepatitis B and C virus(HBV and HCV,respectively)infection markers in densely populated eastern half of China.For this purpose.10 survey sites were selected,i.e.,six sites in urban areas(the city group;Beijing,shangahi and four provincial capitals)and four sites in rural areas(the village group;one village each in Jilin and Shandong provinces,and two villages in Shaanxi Province),About 50 adult women per site volunteered to participate,from whom 494 valid bllod samples were collected.Positivities to HBsAg(HBsAg^ ),anti-HBs(anti-HBs^ )and antiHBc(anti-HBc^ )were examined by RIA methods.and that to anti-HCV(anti-HCV^ )by either EIA or RIA.Those positive to any one of the three HBV infection markers were taken as HBV infection-positive(HBV^ ).The prevalence of HBsAg^ ,HBV^ and anti-HBc^ was 8%,70%and 2.7% in the city group,and 8%,65% and 2.0%in the village group,and no significant difference was found between the two groups.The overall prevalence was 8% for HBsAg^ ,68% for HBV^ ,and 2.4% for anti-HVC^ ,The results were discussed in reference to some 20 papers each on HBV^ and anti-HCV^ prevalence in China published since(1991),The reviewing of these papers of anti-HCV was low(well below 5%),and that no substantial difference was found between the rural and urban populations.
