摘要
目的分析同步尿动力监测下健康女性强烈排尿感时大脑功能网络连接的小世界特征。方法2017年至2018年,招募21例健康女性受试者,在膀胱空虚和强烈排尿感时分别进行大脑静息态功能磁共振扫描。采用Pearson相关分析计算大脑功能连接矩阵;采用配对t检验和Bonferroni校正对膀胱空虚和强烈排尿感时大脑功能连接的拓扑属性进行分析,计算功能网络的小世界属性参数集聚系数、特征路径长度、全局效率、局部效率和局部节点效率。结果2例因头动剔除。其余19例受试者脑功能网络膀胱空虚和强烈排尿感时均具有小世界属性。在强烈排尿感时,网络的集聚系数、特征路径长度、局部效率降低,全局效率增加(P<0.05);左侧额下回和额上回、双侧直回、右侧扣带回、枕中回和颞中回、双侧顶下小叶局部节点效率增加,双侧距状裂周围皮质、舌回和梭状回局部节点效率降低(P<0.05)。结论健康女性在膀胱空虚和强烈排尿感时,脑功能网络都具有低成本、高效率的小世界属性。下尿路功能调控涉及多个脑区组成的复杂脑网络。
Objective To identify the small-world network property of brain functional network provoked by a strong desire to void in healthy women.Methods From 2017 to 2018,21 healthy women were enrolled,and scanned with resting-state functional magnetic resonance imaging under the empty bladder and strong desire to void,respectively.Brain connection matrix was established with Pearson's correlation analysis,and the differences in topologic properties between the two conditions were identified with paired t-test and Bonferroni correction.The small-world parameters,named clustering coefficient(Cp),characteristic path length(Lp),global efficiency(Eglob),local efficiency(Eloc)and nodal efficiency(Enodal)were calculated.Results There were two women dropped down because of head moving.For the other 19 women,the brain connection presented a small-world network property under the both conditions.Compared with the empty bladder,Cp,Lp,and Eloc decreased,and Eglob increased under the strong desire to void(P<0.05);while Enodal increased in left inferior frontal gyrus and superior frontal gyrus;right cingulate gyrus,middle occipital gyrus and middle temporal gyrus;and bilateral gyrus rectus and inferior parietal lobes;and decreased in bilateral fusiform gyrus,calcarine fissure and surrounding,and lingual gyrus(P<0.05).Conclusion Brain functional network presents a small-world network property under both empty bladder and a strong desire to void.The regulation of lower urinary tract function involves the coordination of multiple brain regions.
