AIM To investigate the main current etiologies of cirrhosis in *** We performed a cross-sectional retrospective multicenter study that included eight hospitals in different areas of Mexico. These hospitals provide health care to people of diverse social classes. The inclusion criteria were a histological, clinical, biochemical, endoscopic, or imaging diagnosis of liver cirrhosis. Data were obtained during a 5-year period(January 2012-December 2017). RESULTS A total of 1210 patients were included. The mean age was 62.5 years(SD = 12.1), and the percentages of men and women were similar(52.0% vs 48.0%). The most frequent causes of liver cirrhosis were hepatitis C virus(HCV)(36.2%), alcoholic liver disease(ALD)(31.2%), and nonalcoholic steatohepatitis(23.2%), and the least frequent were hepatitis B virus(1.1%), autoimmune disorders(7.3%), and other conditions(1.0%).CONCLUSION HCV and ALD are the most frequent causes of cirrhosis in Mexico. However, we note that non-alcoholic fatty liver disease(NAFLD) as an etiology of cirrhosis increased by 100% compared with the rate noted previously. We conclude that NAFLD will soon become one of the most frequent etiologies of liver cirrhosis in Mexico.

2014年秋季,采用活体观察法对西藏拉萨市林周县境内的甘曲湿地土壤肉鞭虫进行了多样性研究。共记录了83种肉鞭虫,隶属于2亚门5纲11目16科37属(包括11种未定名种)。其中鞭毛亚门66种,肉足亚门17种。在鞭毛亚门中,植鞭纲(Phytomastigophor... 详细信息

2014年秋季,采用活体观察法对西藏拉萨市林周县境内的甘曲湿地土壤肉鞭虫进行了多样性研究。共记录了83种肉鞭虫,隶属于2亚门5纲11目16科37属(包括11种未定名种)。其中鞭毛亚门66种,肉足亚门17种。在鞭毛亚门中,植鞭纲(Phytomastigophorea)有60种,占鞭毛亚门物种总数的90.9%,动鞭纲(Zoomastigophorea)有6种,占9.1%;在肉足亚门中叶足纲(Lobosea)有10种,占58.82%。丝足纲(Filosea)有2种,占11.76%,太阳纲(Heliozoea)有5种,占29.42%。各样点的Gleason-Margalef从1到5号样点为3.89、3.20、5.57、3.98和4.20,其中3号样点多样性指数最高。1到5样点之间的Jaccard相似性系数均为中等不相似或极度不相似。甘曲湿地土壤肉鞭虫物种丰富,物种组成呈独特性,垂直分布上呈现明显的表聚性。
