OBJECTIVE： To assess the efficacy of acupuncture combined with vitamin B12 acupoint injection versus acupuncture alone to reduce incomplete recovery in patients with Bell＇s palsy. DATA RETRIEVAL： A computer-based online retrieval of Medline, Web of Science, CNKI, CBM databases until April 2014 was performed for relevant trials, using the key words ＂Bell＇s palsy or idiopathic facial palsy or facial palsy＂ and＂acupuncture or vitamin B12 or methylcobalamin＂. STUDY SELECTION： All randomized controlled trials that compared acupuncture with acupuncture combined with vitamin B12 in patients with Bell＇s palsy were included in the me- ta-analysis. The initial treatment lasted for at least 4 weeks. The outcomes of incomplete facial recovery were monitored. The scoring index varied and the definition of healing was consistent. The combined effect size was calculated by using relative risk （RR） with 95% confidence interval （C/） using the fixed effect model of Review Manager. MAIN OUTCOME MEASURES： Incomplete recovery rates were chosen as the primary outcome. RESULTS： Five studies involving 344 patients were included in the final analysis. Results showed that the incomplete recovery rate of Bell＇s palsy patients was 44.50% in the acupuncture combined with vitamin B12 group but 62.57% in the acupuncture alone group. The major acupoints were Taiyang （EX-HN5）, Jiache （ST6）, Dicang （ST4） and Sibai （ST2）. The combined effect size showed that acupuncture combined with vitamin B12 was better than acupuncture alone for the treatment of Belrs palsy （RR = 0.71, 95%CI： 0.58-0.87; P = 0.001）, this result held true when 8 patients lost to follow up in one study were included into the analyses （RR = 0.70, 95%CI： 0.58-0.86; P = 0.0005）. In the subgroup analyses, the therapeutic effect in patients of the electroacupuncture subgroup was better than in the non-electroacupuncture subgroup （P = 0.024）. There was no significant dif- ference in the incomplete recovery rate by subgroup analysis on dru

大规模抽样调查多采用复杂抽样设计，得到具有分层嵌套结构的调查数据集，其中不可避免会遇到数据缺失问题，针对分层结构含缺失数据集的插补策略目前鲜有研究。本文将Gibbs算法应用到分层含缺失数据集的多重插补过程中，分别研究了固定效应模型插补法和随机效应模型插补法，进而通过理论推导和数值模拟，在不同组内相关系数、群组规模、数据缺失比例等情形下，从参数估计结果的无偏性和有效性两方面，比较不同方法的插补效果，给出插补模型的选择建议。研究结果表明，采用随机效应模型作为插补模型时，得到的参数估计结果更准确，而固定效应模型作为插补模型操作相对简便。在数据缺失比例较小、组内相关系数较大、群组规模较大等情形下，可以采用固定效应插补模型，否则建议采用随机效应插补模型。

研究旅游服务贸易出口的决定因素可以帮助寻求当下中国服务贸易巨额逆差的解决方法，从而为政府制定相关政策提供理论基础。然而现有文献中，尚且无人以中国的省级数据作为研究对象，进行旅游服务进出口方面的实证研究。我们的论文填补了这个空缺，利用固定效应对2004-2013年中国各省对世界各国旅游服务贸易出口的平板数据进行综合、全面的回归分析。研究结果表明，中国的旅游出口需求被验证与文献中研究的其他国家与地区有着潜在一致的规律，其中旅游目的地的繁荣程度、游客来源地国家的人口总量、两国的相对价格、两国是否签订自由贸易协定等等变量对旅游服务出口有着尤其显著的影响，与传统重力模型的一般性结论相一致。

20世纪末至21世纪初，我国掀起一场高校合并浪潮，900余所高等学校参与了此次改革。录取分数直接关系到高校的生源质量，是衡量高校合并后质量变化的重要指标。本文使用我国113所“985”高校和“211”高校2001-2018年在全国各省的高考录取分数数据，通过固定效应模型实证分析了高校合并对录取分数的影响。研究发现，高校合并降低了录取最低分，显著提升了录取均分。此外录取分数还与高校所在省份的经济发展水平、志愿填报方式、高中毕业人数、合并规模、合并类型、是否合并医学院、是否为本地招生以及招生区域等因素显著相关。进一步研究显示，大学排名在高校合并与录取分数之间起到了传导的中介作用。

根据属性特征与亲疏程度，可将社会网络划分为不同类别，并且社会网络对主观幸福感的影响存在异质性。研究基于两期“社会网络与职业经历调查”追踪数据（JSNET2014-2016），运用个体固定效应模型，分析了社会网络对中国城镇居民主观幸福感的影响。研究发现：（1）个体的社会网络对主观幸福感存在正向影响，但这一效应主要通过非正式社会网络产生，正式网络的效果并不明显；（2）非正式网络对主观幸福感的影响主要存在于个体的亲缘型社会网络，非亲缘型社会网络的效果并不明显；（3）亲缘型社会网络对幸福感的影响，存在性别、居住地等身份特征的差异，相较而言，对女性、非本地居民的作用效果更为突出。总体而言，我们从文化观念的视角对以上结果做出理解。
