Objective The resting-state functional magnetic resonance imaging(rs-f MRI)method was used to observe brain activity and its functional connection upon electroacupuncture stimulation at bilateral uterine acupoints(EX-CA1),as well as to investigate the mechanism of acupuncture in the treatment of gynecological *** Twenty-two healthy female subjects were stimulated by electroacupuncture at bilateral uterine acupoints;rs-f MRI data of the brain were acquired and *** centrality(DC),amplitude of low-frequency fluctuation(ALFF),and regional homogeneity(ReHo)were used to analyze local spontaneous brain activity via *** independent component analysis was used to evaluate the functional connectivity of the resting brain networks after *** Analytical results showed that the neural activity intensity of the precuneus lobe,orbitofrontal cortex,lingual gyrus,amygdala,and posterior central gyrus decreased after acupuncture(voxel P<0.001,cluster P<0.05).Functional connectivity analysis revealed weakened auditory and right frontal-parietal networks(voxel P<0.001,cluster P<0.05),enhanced visual network(voxel P<0.001,cluster P<0.05),and synergistic auditory network and hypothalamic-pituitary *** Significant differences in neural activity and functional connectivity in specific brain regions were observed after acupuncture intervention at uterine acupoints;the hypothalamic-pituitary system also showed various active states in different brain *** is speculated that the effective mechanism of acupuncture at uterine acupoints is related to the regulation of reproductive hormones,emotional changes,and somatic ***,the methods used in this study could clarify the neural mechanism of uterine-point acupuncture in the treatment of gynecological diseases and may serve as a reference for other studies pertaining to acupuncture.

目的:探讨以问题为导向教育模式对围绝经期女性萎缩性阴道炎激素替代治疗患者的遵医行为及心理影响。方法:纳入2021年2月—2023年2月经本院收治行激素替代治疗的围绝经期女性萎缩性阴道炎患者90例,按随机数字表法设为对照组及观察组,每组45例。对照组予以常规教育模式进行干预,观察组实施以问题为导向教育模式进行干预,比较两组遵医行为、心理状态、生活质量及复发率。结果:观察组遵医行为依从率为95.56%,高于对照组的80.00%(P<0.05);两组教育后SAS、SDS评分低于教育前,且观察组低于对照组(P<0.05);两组教育后GQOL-74评分高于教育前,且观察组高于对照组(P<0.05);观察组复发率低于对照组(P<0.05)。结论:行激素替代治疗的围绝经期女性萎缩性阴道炎患者采用以问题为导向教育模式进行干预,可提升遵医行为,改善负性心理状态,且生活质量获得提高,复发率更低。
