1 资料与方法

1.1 纳入与排除标准 研究设计:语言限英文及中文,病例对照研究。研究对象:经鉴别诊断,排除反复脑卒中、服用药物诱发的帕金森综合征等相关疾病,已经明确诊断的PD患者。暴露因素:PD患者外周血中淋巴细胞亚群的数量。结局指标:与对照组比较PD的发病风险。排除标准:数据重复发表文献;无数据文献;仅有摘要文献;有明显干扰淋巴细胞亚群因素存在的文献。

1.2 检索策略 计算机检索Cochrane Library、Elsevier ScienceDirect、PubMed/Medline、万方数据知识服务平台、中国知网、维普期刊资源整合服务平台,搜索已发表的T、B淋巴细胞亚群与PD相关性的病例对照研究,检索时限为建库至2016-09-30。英文检索词包括“T-cell”“B-cell”“CD3”“CD4”“CD8”“CD19”“Parkinson”,中文检索词包括“T细胞”“B细胞”“淋巴细胞亚群”“帕金森”“CD3”“CD4”“CD8”“CD19”。英文检索式为(“T-cell” OR “B-cell” OR “CD3” OR “CD4” OR “CD8” OR “CD19”)AND(“Parkinson”),中文检索式为(“T细胞” OR “B细胞” OR “淋巴细胞亚群” OR “CD3” OR “CD4” OR “CD8” OR “CD19”)AND(“帕金森”)。

1.3 文献筛选、资料提取与偏倚风险评价 遵循纳入与排除标准,筛选文献、提取资料、评价文献的偏倚风险由两位研究人员分别进行,讨论或交第三方协助裁定以解决分歧。提取内容包括:第一作者、发表时间、种族、样本量、平均年龄、病程、Hoehn and Yahr(HY)评分、帕金森综合评分量表(unified Parkinson′s disease rating scale Ⅲ,UPDRS-Ⅲ)评分及观察指标。采用Newcastle-Ottawa Scale(NOS)文献质量评价量表评价纳入文献的偏倚风险,其中包括8个条目,满分共9分:病例确定是否恰当(1分),病例的代表性(1分),对照的选择(1分),对照的确定(1分),设计和统计分析时考虑病例和对照的可比性(2分),暴露因素的确定(1分),采用相同的方法确定病例和对照暴露因素(1分),无应答率(1分)[6]。5~9分为高质量研究,0~4分为低质量研究。

1.4 统计学方法 采用RevMan 5.2软件进行Meta分析。连续型变量采用加权均数差(WMD)或标准化均数差(SMD)及其95%CI表示。采用χ2检验进行各研究间异质性分析,当P<0.10或I2>50%,表示各文献间存在统计学异质性,采用随机效应模型;若P≥0.10或I2≤50%,表示各文献间无统计学异质性,采用固定效应模型。采用亚组分析,敏感性分析等方法以降低明显异质性,或不合并,单纯描述性分析。以P<0.05为差异有统计学意义。

2 结果

2.1 文献检索结果 经初步检索获得文献1 979篇,进一步阅读题目、摘要及全文后,最终纳入18篇文献[7-24],其中对照组609例,病例组770例。文献筛选流程见图1,纳入文献基本特征见表1。

2.2 纳入文献的偏倚风险评价 纳入文献通过NOS文献质量评价量表评价后得分为5~9分(见表2),均为高质量研究。

2.3.4 B淋巴细胞亚群 4篇文献[8-9,17,23]报道了B淋巴细胞亚群与PD风险的相关性,共226例患者。各研究间有统计学异质性(I2=98%,P<0.001)。因异质性较高,纳入文献较少,根据平均年龄将其分为2个亚组(<65岁亚组,≥65岁亚组)并采用随机效应模型进行分析,其中<65岁亚组异质性消失(I2=0,P=0.40),结果显示病例组与对照组B淋巴细胞亚群计数比较,差异无统计学意义〔SMD=-0.07,95%CI(-0.33,0.20),P=0.62〕;而≥65岁亚组异质性仍较高(I2=99%,P<0.001),因此进行敏感性分析。剔除STEVENS等[8]后,本组仅余1篇文献,但总异质性下降(I2=51%,P=0.13),结果显示病例组与对照组B淋巴细胞亚群计数比较,差异无统计学意义〔SMD=-0.25,95%CI(-0.61,0.12),P=0.19,见图5〕。

本研究也体现了Meta分析的局限性,Meta分析是一种二次分析,纳入研究的缺陷会影响Meta分析结果的可靠性[6]。其次,PD与高龄、遗传、环境等因素均具有相关性,但各研究未能提供全部数据,不能分析多种因素交互作用。此外,使用标准不同,病例选择的随机性,异质性较大,不排除存在一定假阳性及假阴性的可能。因此,有待更大样本研究以进一步验证此次Meta分析结论。
