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.

探讨了用单纱纺纱技术纺制的精梳毛纱及其织物的物理特性。为达此目的，采用了各种单纱纺纱辊纺制不同的单纱纺纱，并对它们进行测量及与常规环锭纺纱工艺纺制的纱进行比较；分别用单纱纺纱工艺和环锭纺纱工艺按3种加捻系数纺制出短纤纱，然后将两种工艺纺出的纱在小样机上织成2/2斜纹织物，将坯布精练、烘干、汽蒸，最后罐蒸。然后测量织物的物理性能，根据单纱纺纱工艺纺制的纱的机械特性及成纱原理用KEs-FB系统对这些织物的物理特性加以测量和研究。

The availability of liquid chromatography ultraviolet nuclear magnetic resonance mass spectrometry (LC UV NMR Ms)integrated systems is providing greater information content and confidence for a variety of sample types, such asdrug metabolites, natural products, impurities, and degradants. A wide range of experimental strategies can be pur sued,highlighting the flexibility and performance possible with this multihyphenated technique.
