ABSTRACT
Network pharmacology, molecular docking and in vivo experiments were used to explore the pharmacodynamic basis and potential mechanism of Danggui Sini Decoction in the treatment of primary dysmenorrhea(PD). The chemical constituents of Danggui(Angelicae Sinensis Radix), Guizhi(Cinnamomi Ramulus), Tongcao(Tetrapanacis Medulla), Baishao(Paeoniae Radix Alba), Xixin(Asari Radix et Rhizoma), Gancao(Glycyrrhizae Radix et Rhizoma), and Dazao(Jujubae Fructus) from Danggui Sini Decoction were retrieved through TCMSP(Traditional Chinese Medicine Systems Pharmacology Database), and the action targets of Danggui Sini Decoction were collected through DrugBank. "Primary dysmenorrhea" and "dysmenorrhea" were used as the key words to search the corresponding targets in the GeneCards, OMIM and TTD databases, and then the intersection targets of Danggui Sini Decoction and the primary dysmenorrhea targets were taken for reverse screening to obtain the corresponding active ingredients. Cytoscape 3.6.1 software was used to construct a traditional Chinese medicine-compound-target-disease network; STRING database was used to build a protein-protein interaction(PPI) network; Gene ontology(GO) function enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were conducted by using DAVID database. The action mechanism of the intersection targets were then predicted, and a histogram chart and bubble chart were drawn for visualization. Then the top five targets in the PPI network were used for docking with the most compounds. In animal experiments, Sprague Dawley(SD) female rats were used to establish a primary dysmenorrhea model by intraperitoneal injection of diethylstilbestrol once a day. A total of 60 SD female rats were randomly divided into 6 groups, namely control group, model group, Danggui Sini Decoction low(1.5 g·kg~(-1)), medium(3.0 g·kg~(-1)), high(6.0 g·kg~(-1)) dose groups, and ibuprofen(20 mg·kg~(-1)) positive control group, with 10 rats in each group. From day 4, except for the control group, rats in the other groups were given intragastric administration of corresponding drugs, and the control group received intragastric administration of normal saline for 7 consecutive days. The number of writhing before and after the administration, the ute-rine contraction inhibition rate and the uterine index after administration were observed, and ELISA assay was used to detect the levels of prostaglandin-endoperoxide synthase 2(PTGS2) and vascular endothelial growth factor A(VEGFA) in the tissues of each group as well as the levels of serum inflammatory factors interleukin 1(IL-1), interleukin 6(IL-6), and tumor necrosis factor-alpha(TNF-α). According to network analysis, 7 Chinese medicines contained 114 active ingredients, 149 targets, and 30 common target genes with PD were obtained. The key targets included VEGFA, IL6, PTGS2, TNF, etc.; GO function enrichment analysis showed a total of 399 terms(P<0.05) were obtained, 353 of which were biological process(BP) terms, 21 were cell composition(CC) terms, and 25 were molecular function(MF) terms. In KEGG pathway enrichment analysis, 14 signaling pathways were obtained, 3 of which were related to inflammation, namely arachidonic acid metabolism, MAPK signaling pathway and NOD-like receptor signaling pathway. The compounds in Danggui Sini Decoction can play a therapeutic role in the treatment of PD by acting on VEGFA, IL-6, PTGS2, TNF and other targets to regulate arachidonic acid and inflammatory signaling pathways.

Objective@#The purpose of this study is to understand associations of developmental coordination disorders (DCD) and sensory integration disorders (SID) with family environment for motor development.@*Methods@#A questionnaire survey was conducted among 309 parents of 3-4 years old children in two kindergartens in Beijing selected by clustering sampling, using Development Coordination Disorder Questionnaire, Sensory Integrative Function Scale and Family Environment Scale on Motor Development for Urban Preschool Children.@*Results@#Among the 309 children, the prevalence of DCD was 8.1% with gender difference with boys(11.0%) significantly higher than girls(4.4%)(χ2=6.71，P<0.05). The rate of SID was 42.1% with no significant gender difference(χ2=7.32，P=0.62). The concordance rate of SID and DCD(23/25，92.0%) was related to family environment for motor development. Specifically, parental rearing patterns was the primary factor for co-occurrence of SID and DCD(B=-0.37, OR=0.69, 95%CI=0.54-0.89，P<0.01).@*Conclusion@#The development of SID and DCD is closely related among preschoolers. Parental rearing pattern plays an important role in SID and DCD.

ABSTRACT
Objective To investigate the cyclical changes of the apparent diffusion coefficient (ADC) values of the normal uterine zonal structures and explore physiological mechanism and clinical significance of the changes .Methods Nineteen healthy young fe‐male volunteers were selected to receive DWI (b=0 and 1 000 s/mm2 ) scan during periovulatory ,late secretory and menstrual pha‐ses .The ADC values of endometrium ,junctional zone and myometrium were measured and the differences of the ADC values were analyzed .Results The ADC values among three structures were significantly different in three phases (P< 0 .05) .The ADC value of myometrium was highest and the second was endometrium and the last was junctional zone .The differences of specific uterine zonal structures in different phases were statistically significant (F=55 .674 ,P<0 .05) .There was a interaction effect between menstrual cycle and uterine structures .Conclusion The effect of zones and different phases of the menstrual cycle in young women on ADC val‐ues of uterine structures should be considered when use ADC values to diagnose uterine diseases .
ABSTRACT
BACKGROUND/AIMS: Increasing evidence shows involvement of psychological disorders in functional dyspepsia (FD), but how psychological factors exert their influences upon FD remains largely unclear. The purpose of the present study was to explore the brain-based correlations of psychological factors and FD. METHODS: Based on Fluorine-18-deoxyglucose positron emission tomography-computed tomography, the altered cerebral glycometabolism was investigated in 40 FD patients compared with 20 healthy controls during resting state using statistical parametric mapping software. RESULTS: FD patients exhibited increased glucose metabolism in multiple regions relative to controls (P < 0.001, family-wise error corrected). After controlling for the dyspeptic symptoms, increased aberrations persisted within the insula, anterior cingulate cortex (ACC), middle cingulate cortex (MCC) and middle frontal cortex (midFC), which was related to anxiety and depression score. Interestingly, FD patients without anxiety/depression symptoms also showed increased glycometabolism within the insula, ACC, MCC and midFC. Moreover, FD patients with anxiety/depression symptoms exhibited more significant hypermetabolism within the above 4 sites compared with patients without anxiety/depression symptoms. CONCLUSIONS: Our results suggested that the altered cerebral glycometabolism may be in a vicious cycle of psychological vulnerabilities and increased gastrointestinal symptoms.

BACKGROUND AND PURPOSE: Whether or not migraine can cause cumulative brain alterations due to frequent migraine-related nociceptive input in patients is largely unclear. The aim of this study was to characterize longitudinal changes in brain activity between repeated observations within a short time interval in a group of female migraine patients, using resting-state functional magnetic resonance imaging. METHODS: Nineteen patients and 20 healthy controls (HC) participated in the study. Regional homogeneity (ReHo) and functional interregional connectivity were assessed to determine the focal and global features of brain dysfunction in migraine. The relationship between changes in headache parameters and longitudinal brain alterations were also investigated. RESULTS: All patients reported that their headache activity increased over time. Abnormal ReHo changes in the patient group relative to the HC were found in the putamen, orbitofrontal cortex, secondary somatosensory cortex, brainstem, and thalamus. Moreover, these brain regions exhibited longitudinal ReHo changes at the 6-week follow-up examination. These headache activity changes were accompanied by disproportionately dysfunctional connectivity in the putamen in the migraine patients, as revealed by functional connectivity analysis, suggesting that the putamen plays an important role in integrating diverse information among other migraine-related brain regions. CONCLUSIONS: The results obtained in this study suggest that progressive brain aberrations in migraine progress as a result of increased headache attacks.
