跨文化传播在全球语境下面临的问题

近几年来,全球文化传播尤其是美国大众文化的锋向道劲,导致传播业界的喜忧参半。随着自觉不自觉情愿不情愿的全球化之势,以及全球化与视觉文化、大众文化、消费文化的杂交,使得在全球范围内的跨文化问题日趋明显,与此同时,随着跨文化传播的进程,文化传染和文化接合的共同征候在全球范围内日益趋同,这个问题十分值得研究。

Relationship between alanine aminotransferase levels and metabolic syndrome in nonalcoholic fatty liver disease

Objective:To investigate the relationship between alanine aminotransferase (ALT)levels and metabolic syndrome (MS)in nonalcoholic fatty liver disease(NAFLD).Methods:A total of 26527 subjects who received medical health checkup in our hospital from January 2005 to July 2007 were enrolled in the study.The diagnosis of fatty liver was based on ultrasound imaging.MS Was defined according to the criteria of the Adult Treatment Panel Ⅲ.ALT,triglyceride(TG),high density lipoprotein cholesterol(HDL-c),fasting plasma glucose(FPG),height,weight,waist circumference(WC),systolic blood pressure (SBP)and diastolic blood pressure(DBP)were measured in each subject to analyze the relationship between MS and ALT activity.Results:(1)The prevalence of NAFLD in men(30.94%)was significantly higher than that in women(15.65%);(2)The incidence of MS in NAFLD(33.83%)was significantly greater than that in non-NAFLD(10.62%);(3)Of the 6470 subjects with NAFLD,in the age-adjusted partial correlation analysis,there were statistically significant correlations between the ALT levels and most metabolic risk factors in each sex(P＜0.01),except that ALT levels had no correlation with HDL-c in women.Moreover,in the multiple stepwise regression analysis,SBP lost its significance,and WC,body mass index(BMI),age,DBP,TG and FPG were independently associated with ALT levels in both sexes (P＜0.05).HDL-c remained significant and was independently related to ALT leveis in men;(4)ALT levels were significantly higher in subjects with MS compared to those without MS(P＜0.001).Mean ALT levels increased with the number of MS cornponents in each sex (P.＜0.05 for trend).Conelusion:We found a strong relationship between ALT leveIs and MS in NAFLD and revealed that the cluster of MS components might be the predictor for ALT elevations.     

Severe short-bowel syndrome after total small bowel resection

Extensive intestine resection may result in short bowel syndrome (SBS) which is difficult of manage. This study reports a rare SBS case in a 6-year-old boy following resection of total jujunoileum and right colon. Our experience in 4-years follow-up and literature reports on SBS is discussed. The purpose of this study was also to evaluate the nutritional absorptive capacity and intestinal adaptation. In the 15th postoperative month, barium x-ray study showed a significantly extended and enlarged duodenum and colon. The intestinal transit time was prolonged to 22 hours. The absorption rate of palmic acid, glycine and D-xylose had increased from 57%, 50% and 4% respectively in the 15th postoperative month, to 75%, 65% and 6% in the 2nd postoperative year. His absorptive capacity allowed him normal oral feeding and normal school life. Our data confirmed the reports of the colon as an energy-salvage organ, and suggested that it may have some capacity to absorb long-chain fatty acids and amino acids.     

高职院校共享型实训基地建设的『喜』与『忧』

共享型实训基地建设的特点是:政府、学校、企业协作共建、资源共享,"对内实行企业化管理,对外实行准市场化运作"。目前大多数由政府扶持企业共建的共享型实训基地已初步建成,集"教学、科研、生产、培训"多种功能于一体。但这些示范性实训基地,还存在着适用性不强、软硬件不配套、开放力度不够、实训师资短缺、管理水平不高等问题,有待改进。
