Genetic diseases, such as Type II diabetes, are caused by a combination of environmental factors and mutations in multiple genes. Patients who have been diagnosed with such diseases cannot easily be treated. However, many diseases can be avoided if people at high risk change their living style, one example is their diet. Genome association study has been used to identify the risk factor of genetic disease. With the development of DNA microarray technique, it is possible to access the human genetic information related to specific diseases. This paper uses a combinatorial method to analyze the genetic case-control data for Type II diabetes. A distance based cluster method has been applied to publicly available genotype data on Type II diabetes for epidemiological study and achieved a high accurate result.

The Both environmental and genetic factors have roles in the development of some diseases. Complex diseases, such as Crohn's disease or Type II diabetes, are caused by a combination of environmental factors and mutations in multiple genes. Patients who have been diagnosed with such diseases cannot easily be treated. However, many diseases can be avoided if people at high risk change their living style, one example being their diet. But how can we tell their susceptibility to diseases before symptoms are found and help them make informed decisions about their health? With the development of DNA microarray technique, it is possible to access the human genetic information related to specific diseases. This paper uses a combinatorial method to analyze the genetic data for Crohn's disease and search disease-associated factors for given case/control samples. An optimum random forest based method has been applied to publicly available genotype data on Crohn's disease for association study and achieved a promising result.

Dear Editor,Breath analysis is a promising diagnostic approach for various conditions[1,2].It is based on the identification of volatile organic compounds(VOCs)emitted in the breath,which creates a unique volatolomic signature[3].Owing to their characteristics,VOCs can be measured non-intrusively from the breath or other body sources[3,4].Several studies have shown the diagnostic potential for a variety of conditions based on VOC analysis[5-9].Malignant diseases,where early detection is crucial,are the main focus of VOC analysis,with lung cancer(LC)and gastric cancer(GC)being the most *** and GC together were responsible for approximately 2.5 million deaths globally in 2018[10].The aim of VOC analysis of the breath using sensors is to identify a“VOC-print”comprising the total abundances and ratios of the compounds in the breath,giving an overall unique chemical pattern[11].

聚丙烯酰胺(PAM)作为一种高效絮凝剂被广泛应用于矿井水处理过程中,PAM残留物丙烯酰胺(AM)单体存在于矿井水处理环节中,而AM已被国家癌症中心列为ⅡA类致癌物。为揭示PAM残留物AM在矿井水处理中的迁移规律,对10个矿区的矿井水处理环节进行了检测分析,并通过混凝沉淀与过滤实验研究了PAM投加量、分子量、水解度、矿井水pH值和含盐量等因素对AM质量浓度和处理效果的影响。结果表明:在调研的10个矿区的矿井水处理中,有80%的澄清(沉淀)池出水AM质量浓度>0.0005 mg/L,在0.0017~0.0875 mg/L,有60%的过滤出水AM质量浓度﹥0.0005 mg/L,在0.0011~0.0767 mg/L,过滤过程对AM的去除率在12.3%~99.1%,矿井水常规处理难以保证AM质量浓度满足饮用水标准,回用于饮用水需考虑PAM选型和投加量的优化,或采用反渗透等膜技术处理;在试验条件下(PAM投加量0.5~2.5 mg/L、分子量500万~1800万、水解度5%~30%、聚合氯化铝投加量为80 mg/L),AM质量浓度在沉淀与过滤2个处理环节均随各因素水平的增加而呈现先减小后增加的趋势,过滤过程对AM的去除率在30.0%~58.3%,当PAM投加量为1.0 mg/L、分子量为1200万、水解度为22%,原水pH值为7、电导率为2000μS/cm时,沉淀和过滤出水AM质量浓度最低,实验中最低值分别为0.0026和0.0012 mg/L。

区别于其他类别住宿产品,精品酒店多具有鲜明的文化特色,主题文化的定位与价值取向不仅仅是企业行为,其对旅游地的影响应该得到关注和重视。文章以文化生态理论为基础,运用质性研究方法,采取实地调研、文本分析和深度访谈等做法,对长三角地区26家精品酒店进行实证分析,研究表明:(1)精品酒店在主题文化定位上,呈现出以利用与依托旅游资源为主、以创设文化与休闲氛围为主两大主题,两大主题给旅游地带来不同影响。(2)精品酒店、住店客人、地方政府、社区居民及专家学者等不同群体在利益诉求上,形成对主题文化认识的分异与调和的内在逻辑。(3)主题文化的价值取向体现在传统文化空间生产、酒店文化消费以及酒店服务文化等三个方面,其价值困境表现在投资行为并不为文化负责、公共资源的商业化利用和特定语境下的奢华消费。文章从政府和酒店两个层面提出优化精品酒店主题文化建设和价值取向的对策建议。
