目的通过泰兴肝癌环境病例对照研究,搞清肝癌环境危险因素,进一步证实饮水等与肝癌的关系,从而采取预防措施。方法选择以人群为基础的病例对照调查方法,通过问卷、采血,测定对两种病毒的感染、黄曲霉毒素(AFB1)摄入后白蛋白加合物和机体内基因检测,并进行统计分析,以判断当地肝癌主要危险因素。结果HBsAg比数比(OR)=5.68(95%可信限CI3.80-8.51),丙型肝炎OR=4.19(95%CI1.72-10.22),两种肝炎均为肝癌危险因素,但以乙型肝炎为主。居民摄入霉变食物OR=2.25(95%CI1.39-3.64)。1/2病例和1/3对照有饮生水习惯,经常饮生水者OR=4.60(95%CI1.30-16.30)。肝癌家族史OR=2.99(95%CI1.78-5.01)。吸烟和饮酒未达到危险水平。多吃蔬菜和水果有保护作用OR=0.58(95%CI0.38-0.89)。摄取霉变食物或AFB1加合物,饮生水与HBsAg有联合作用。肝癌与存在基因MTHFR anyT,并同时具有三大环境因素者(摄取霉变食物,饮生水与HBsAg)有明显的联合作用,OR由22跃升到72倍。IFNA17亦与HB-sAg和AFB1加合物有联合作用。结论泰兴肝癌与三大环境因素(HBsAg、摄取霉变食物,饮生水)有密切关系。两种基因的多态,尤其MTHFR anyT值得关注。管水、改粮和防肝炎仍然是预防肝癌的重要措施。

Previous studies have identified trust as one of the key factors in the technology acceptance of autonomousvehicles. As these studies mostly investigated the population in general, little is known about segment-specific ***, the widely used survey methods are less able to capture the deeper forms of trust—which neuroscientificmethods are much better suited to capture. The main objective of our research is to study trust as one of the key factors oftechnology acceptance related to autonomous vehicles by using neuroscientific methods for specific consumer ***-time eye-tracking tests were applied to a sample of 113 participants, combined with a posttest self-report. The testswere carried out under laboratory conditions during which our subjects watched videos recorded with the internal camerasof autonomous vehicles. Based on the fixation count, total fixation duration, and pupil dilation, we empirically verified thatthe trust level of all five identified segments is relatively low, while the trust level of the “traditional rejecting” segment is thelowest. An increase in trust level can be shown if the subjects receive extra information about the journey. Anotherimportant finding is that the self-reported trust level is not always congruent with the eye-tracking analysis results;therefore,combined approaches can lead to greater measurement validity.
