METHODS: Sixty ODE patients were recruited, and these patients were randomly divided into two groups. One group received artificial tear treatment, and the other group received a new eyelid warm moist air device combined with eyelid massage treatment. Subjects completed the ocular surface disease index (OSDI), which was followed by fluorescein tear breakup time (BUT), corneal fluorescein staining (CFS), Schirmer I test (SIt) and meibomian gland secretion function evaluation at baseline, and 2 and 4wk after treatment. RESULTS: In these 60 patients, 48 patients (23 in artificial tear treated group and 25 in the new warm moist air device assisted with eyelid massage treated group) were positive for meibomian gland dysfunction (MGD). Compared to artificial tear treatment, the new warm moist air device assisted with eyelid massage treatment showed favorable therapeutic effect on OSDI (FGroup=41.63, P<0.01), BUT (FGroup=60.47, P<0.01) and the grade of meibum quality (FGroup=12.12, P<0.01) during 4wk treatment in this study. No significant difference was found in SIT (FGroup=0.17, P>0.05), CFS (FGroup=1.79, P>0.05) and meibomian gland expressibility (FGroup=0.68, P>0.05) between the two groups during 4wk treatment. CONCLUSION: This new eyelid warm moist air device assisted with eyelid massage has favorable therapeutic effect over artificial tear in ODE treatment.

最低工资与企业价格加成

本文利用1998-2007年中国工业企业数据库和各地级市最低工资数据,从价格加成视角考察了最低工资对企业经营绩效和资源配置效率的影响,并重点探讨了可能的影响渠道。研究发现:最低工资上涨显著降低了企业的价格加成,削弱了企业盈利能力。这意味着在短期最低工资潜在的成本效应大于其生产率提升效应。这一影响对不同特征的企业存在异质性,企业资本密集度和平均工资越低,其价格加成受到最低工资的影响越大。此外,最低工资上涨还会降低城市行业内价格加成分散度,有利于行业内资源错配的改善。国家自然科学基金面上项目(71273167);;上海市教育委员会、上海市教育发展基金会2014年度“曙光计划”项目(14SG51);;霍英东青年教师基础研究课题(141085)的资
