还原型谷胱甘肽联合多烯磷脂酰胆碱治疗急性药物性肝损伤的临床疗效

目的：探讨还原型谷胱甘肽联合多烯磷脂酰胆碱治疗急性药物性肝损伤的临床疗效。方法随机抽取2012年4月至2014年4月本院接诊的110例急性药物性肝损伤患者作为研究对象,按照随机数字表法将其分为两组,对照组患者予以多烯磷脂酰胆碱治疗,观察组患者在其基础上加用还原型谷胱甘肽治疗,4周后比较两组患者的肝功能指标天冬氨酸转氨酶（AST）、丙氨酸转氨酶（ALT）、血清总胆红素（TBiL）的变化及临床疗效。结果治疗后,观察组患者总有效率高于对照组,组间比较差异有统计学意义（P＜0.05）;观察组各项肝功能指标低于对照组,治疗期间两组患者耐受性较好,均未发生明显不良反应。结论还原型谷胱甘肽联合多烯磷脂酰胆碱治疗急性药物性肝损害疗效明显,可有效改善患者的肝功能水平,且患者耐受性良好。     

农民工工伤保险问题实证研究

参加工伤保险是农民工的基本权益之一,本研究以杭州市农民工为例,进行了专项调查,调查发现,农民工对工伤保险制度还不大了解,有70%多的没有参加工伤保险,而且高危行业参保的比例反而不高,分析了影响农民工参加工伤保险其它因素。最后提出了相关对策建议。     

安全气囊召回及缺陷判定流程研究

交通事故中安全气囊存在的缺陷不仅会使其失去保护乘员的作用,而且会导致乘员的额外损伤。文章针对国内安全气囊缺陷调查技术、标准和监管制度的缺失,充分调研了国内外安全气囊召回现状,分析了美国政府参与调查的气囊召回案件的特点。最后,结合国外缺陷调查经验、判定流程和气囊缺陷判定关键技术,制定出我国汽车安全气囊缺陷判定通用流程,并开发了相应的判定软件。研究结果可促进安全气囊缺陷判定的标准化和规范化,从而降低相关判定工作的技术难度和管理成本,有利于保护车辆乘员的安全。     

Dumping and Injury Margins in Markets with Horizontal as well as Vertical Product Differentiation

This paper examines the GATT/WTO rules for anti-dumping measures in a duopoly model with both horizontal and vertical product differentiation. The GATT/WTO rules allow for anti-dumping measures if domestic producers, exposed to price discrimination, also demonstrate injury where price-undercutting is an important indicator of the latter. The paper shows that the procedure for calculating injury is flawed due to negligence of quality differences in the calculation of the margin of price-undercutting. This gives countries with high-quality producers an option to practice protectionism. This asymmetry between countries in ability to implement anti-dumping measures predominantly favors the developed countries which are specialized in producing high-quality products. The paper suggests an overall critical look at the lenient rules for implementing anti-dumping measures—especially the rules for injury determination—in order to restrict the use of such measures to a minimum and to move the world economy closer to free trade.     

工伤保险与雇主责任险的异同——从赔付规则角度谈的异同

工伤保险属于社会保险,是法定保险范畴;雇主责任险属于商业保险,确切的说属于财产保险中的责任险类别。结合案例,探讨工伤保险与雇主责任险的异同,以便更好的理解两者。

Pillion riders' cloth related injuries and helmet wearing patterns: a study of Lahore,Pakistan

This study aims at investigating the burden and pattern of clothing related pillion riders' injuries and their helmet wearing pattern in Lahore, Pakistan. Data were collected for nine months (July 2013 to March 2014), reporting 13,248 motorcycle related injuries, out of which 8751 (66%) cases were related to the clothing related pillion riders' injuries. Out of these injuries 10.30% were severe injuries which can be prevented or reduced by proper safety measure, e.g. wearing helmet. It was also found that most of the fatalities were not wearing helmet. Injuries due to wearing of loose fitting clothes and absence of helmet are not uncommon in Pakistan and other underdeveloped parts of the world. Such accidents may be reduced by creating awareness and safety sense in the riders, where use of safe dress and helmet should be encouraged in order to avoid such fatal damages.     

加味黄芪桂枝五物汤联合西药治疗糖尿病周围神经病变患者的临床疗效

目的探讨加味黄芪桂枝五物汤联合西药治疗糖尿病周围神经病变(DPN)患者的临床疗效。方法选取2019年3—9月辽宁中医药大学附属医院收治的100例DPN患者作为研究对象,利用随机分配法将其分为对照组和观察组,每组50例。对照组患者在常规治疗(控制血糖、饮食指导、运动处方建立)基础上采用硫辛酸注射液治疗,观察组在对照组西医治疗基础上予以加味黄芪桂枝五物汤口服。比较两组患者治疗前后中医主症积分、一氧化氮(NO)、前列环素(PGI2)、多伦多临床评分系统(TCSS)评分、密西根神经病变筛选表(MNSI)评分变化情况。结果治疗后,两组中医主症评分、NO及PGI2表达水平、TCSS评分、MNSI评分有所改善,且观察组明显优于对照组,差异有统计学意义(P<0.05)。结论在西医常规治疗基础上采用加味黄芪桂枝五物汤治疗DPN,可有效改善患者微循环,改善肢体麻凉、疼痛等症状,减轻患者痛苦。
