Dynamic Observation on Change of T3, T4 and TSH in PMS Patients with Liver-qi Invasion Syndrome and Liver-qi Depression Syndrome in Each Phase of Menstrual Cycle / 世界科学技术-中医药现代化

This study was aimed to reveal the roles of biological factors T3, T4 and TSH in the pathogenesis of liver-qi invasion syndrome and liver-qi depression syndrome of premenstrual syndrome (PMS) in the body. Thus, we may expound the connotation of conceptpotential stagnation ofqi and blood. Female workers of Jinan and Qingdao were selected as target groups by epidemiological cross-sectional survey. And specially trained investigators were responsible for screening patients referred to criterion on the international diagnostic standards and syndrome diagnosis of PMS. Patients' blood was taken as samples during the follicular phase (6 to 14 days), luteal phase (15 to 23 days), premenstrual phase (24 to 28 days) and the menstrual phase (1 to 5 days), respectively. Blood samples were disposed according to requirements of radioimmunoassay. Single factor analysis of variance was used in the comparison with the level of T3, T4 and TSH in menstrual blood for different time intervals of the case group and the normal group by SPSS 10.0 statistical software. The results showed that T3 levels of patients with either syndrome were significantly reduced during the premenstrual phase and the menstrual phase (P < 0.05). There were no significant changes on the level of serum T4 and TSH before and after the occurrence of the disease. Both of them were significantly increased during each phase of the menstrual cycle. It was concluded that changes of T3, T4 and TSH were one of the mechanisms in disease with liver-qi invasion syndrome and liver-qi depression syndrome. The micro change was the essence ofpotential stagnation of qi and blood, which was the body condition of this disease.

Application of fMRI Technology in Exploration of Central Brain Localization among Premenstrual Syndrome Patients with Liver-qi Depression in Resting-state / 世界科学技术-中医药现代化

This study was aimed to explore brain regions which were closely related to the disease onset of premenstrual syndrome (PMS) with liver-qi depression. The BOLD-functional magnetic resonance imaging (fMRI) was used in the study. The processing of imaging data was based on the SPM 8 software and the REST software of the matlab platform. Each cluster was more than 389 continuous voxel. The brain region with single voxel of P < 0.05 (corrected) was defined as region with statistical significance. The 2 Sample T-Test was applied in the case group and the control group. The results showed that compared with the normal control group, the frontal lobe, occipital lobe, insula, limbic lobe, basal nuclei, and cingulate gyrus were activated in the PMS with liver-qi depression cases. It was concluded that the disease onset of PMS with liver-qi depression cases was related to brain regions such as frontal lobe, occipital lobe, insula, limbic lobe, basal nuclei, and cingulate gyrus.
