摘要:

文题释义:
CUMS抑郁模型:是一种慢性不可预知轻度应激(Chronic unpredictable mild stress,CUMS)模型。运用各种刺激方法,在动物不可预知的情况下长期施加于实验动物引起其情绪改变的造模方法。此造模方法已被广泛应用于抑郁症研究,且该方法造模所引起的模型动物病理生理改变与人类抑郁症相似。
抑郁样行为:是实验动物抑郁状态的行为学表现,主要通过强迫游泳的潜伏期、悬尾测试的潜伏期以及糖水偏好指数等行为学测试指标反映实验动物的抑郁状态。

目的:抑郁症是全球疾病负担的五大主要原因之一,目前可用的抗抑郁药物疗效低、起效慢、不良反应严重,而运动是治疗抑郁症的一种较好的方式。文章系统评价了运动对慢性不可预知轻度应激(CUMS)模型鼠抑郁相关行为的干预效果。 
方法:检索万方、中国知网、PubMed、Embase和Web of Science数据库,检索文献时限为2000-01-01/2022-02-28,收集跑台、游泳、转轮等运动对慢性不可预知轻度应激(CUMS)抑郁动物模型强迫游泳、悬尾、糖水偏好行为学影响的研究。由2位研究者按照纳入标准独立完成文献筛选、资料提取及SYRCLE动物实验偏倚风险评估工具进行方法学质量评价,运用RevMan 5.3和Stata 13.0分析软件进行统计分析。 
结果:共纳入23篇对照动物实验文献,运动组实验动物301只,对照组302只。Meta分析结果显示:①运动能够显著降低抑郁模型鼠强迫游泳测试潜伏期[SMD=-3.93,95%CI:(-4.88,-2.98),P < 0.000 01]及悬尾测试潜伏期[SMD=-4.42,95%CI:(-5.62,-3.23),P < 0.000 01];②运动同样可以提高糖水偏好指数[SMD=2.37,95%CI:(1.62,3.11),P < 0.000 01];③悬尾测试中对运动方式进行亚组分析可以降低异质性[SMD=-3.68,95%CI:(-4.16,-3.21),P < 0.000 01],但并不影响运动效果。
结论:运动能有效改善慢性不可预知轻度应激(CUMS)模型鼠强迫游泳、悬尾、糖水偏好的抑郁样行为。运动方式可能是影响悬尾测试行为的异质性来源;造模时间、干预阶段、运动方式及运动时间不是影响运动改善抑郁效果的主要因素。
缩略语:慢性不可预知轻度应激:chronic unpredictable mild stress,CUMS

Abstract: OBJECTIVE: Depression is one of the five major causes of the global burden of diseases. Currently available antidepressants have low efficacy, slow onset, and serious side effects, while exercise is a better way to treat depression. This paper systematically evaluates the effects of exercise on depression-related behaviors in chronic unpredictable mild stress (CUMS) animal models. 
METHODS: A systematic literature search from January 1, 2000 to February 28, 2022 was performed in WanFang, CNKI, PubMed, Embase, and Web of Science databases. Studies regarding the effects of treadmill running, swimming, and voluntary wheel running on forced swimming, tail suspension, and sugar water preference behavior of CUMS animal models were collected. Literature screening, data extraction and methodological quality assessments were completed by two researchers independently. The SYRCLE tool was used to assess the risk of bias in the included studies. RevMan 5.3 and Stata 13.0 analysis software were used for statistical analysis.
RESULTS: A total of 23 controlled experimental studies were included, including 301 rodents in exercise group and 302 rodents in control group. Meta-analysis results showed that exercise significantly reduced the forced swimming latency [standardized mean difference (SMD)=-3.93, 95% confidence interval (CI): (-4.88, -2.98), P < 0.000 01] and tail suspension latency [SMD=-4.42, 95% CI: (-5.62, -3.23), P < 0.000 01] in CUMS modeling rats and mice. Exercise also increased the index of sucrose preference test [SMD=2.37, 95% CI: (1.62, 3.11), P < 0.000 01]. Subgroup analysis of exercise modes in the suspension test reduced heterogeneity [SMD=-3.68, 95% CI: (-4.16, -3.21), P < 0.000 01], but it did not affect the exercise effect.
CONCLUSION: Exercise can effectively improve depression-like behaviors of forced swimming, tail suspension, and sucrose preference tests in CUMS model rodents. The mode of exercise may be the source of heterogeneity affecting the behavior of the suspension tail test. Modeling time, exercise stage, exercise mode, and exercise duration are not the main factors that affect the effect of exercise on depression.
