ABSTRACT
Objective:To explore the material basis and molecular mechanism of Liu-He-Dan (LHD) in treating acute pancreatitis (AP).Methods:Active chemical components of LHD, their corresponding targets and related AP pathogenic genes were searched and selected in the Encyclopedia of Traditional Chinese Medicine (ETCM) and disease information related databases (OMIM, DisGeNET, HPO, and NCBI), respectively. The protein-protein interaction (PPI) was analyzed through the STRING database. Enrichment analysis on those targets was performed by using CPBD and STRING databases to examine the function and pathway involved in the treatment of AP by active chemical components of LHD. Finally, " Chinese medicinal materials-active chemical components-targets-pathways" network was constructed by Cytoscape 3.6.0.Results:Network analysis showed that a total of 111 active chemical components of LHD were correlated with 39 targets of AP. The gene ontology functional enrichment analysis of 39 targets by CPBD and STRING databases obtained 575 enrichment results of biological process, 49 results of molecular function and 26 results of cellular components; Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis obtained 46 enrichment results involved in pancreatic secretion, bile secretion, RRAR signaling pathway, arachidonic acid metabolism and calcium signaling.Conclusions:The molecular mechanism of LHD in the treatment of AP by multiple components, multiple targets and multi-signaling pathways was preliminarily determined, which provides a basis for further analysis on active chemical components of LHD and molecular function.
ABSTRACT
Objective To investigate the correlation between the types of constitution in TCM and the sleep status in the PLA Navy divers. Methods Eighty-nine PLA Navy divers who performed 10m diving professional training were selected. Constitution in TCM was classified and determined by the standardized standard Constitution in Chinese Medicine Questionnaire, sleep status was evaluated by the Pittsburgh Sleep Quality Index. Results 62.9% of Navy divers were the mild constitution in TCM. The eight kinds of the biased constitution in TCM are ranked with yang deficiency, phlegm-dampness, dampness-heat, qi deficiency, yin deficiency, blood stasis, qi stagnation and special intrinsic quality. Among 78 Navy divers with good sleep quality, there were 49 divers (72.1%) with the mild constitution in TCM and 19 (27.9%) with the biased constitution in TCM. Among 21 Navy divers with poor sleep quality, there were 7 divers (33.3%) with the mild constitution in TCM (accounting for) and 14 (66.7%) with the biased constitution in TCM. For Navy divers with poor sleep quality, the sleep quality scores were positive correlated with the blood stasis constitution in TCM (r=0.481,P<0.05). Conclusion Sleep status is correlated with the types of the constitution in TCM, and regulating constitution in TCM can improve sleep quality in PLA Navy divers.
ABSTRACT
Objective To explore the correlation between TCM constitution and sleep status in escort troops. Methods Standardized TCM Constitution Questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used to investigate escort troops. Factors of PSQI and constitution types were analyzed. Results The results of PSQI showed the number of escort troops who had bad sleeping (PSQI>7) was 64, which accounted for 46%of the escort troops, among which, 45 people (70.3%) were justified as biased constitution, while 19 were normal constitution (29.7%). The top three biased constitution in bad sleeping were:qi deficiency, phlegm-dampness and dampness-heat. PSQI factors such as sleep disorder, daytime dysfunction and total score had positive correlation with qi deficiency, yang deficiency, yin deficiency, dampness-heat and blood stasis, and negative correlation with normal constitution. Conclusion Sleep condition of escort troops has correlation with TCM constitution, which indicates that sleep status could be improved by regulating TCM constitution.
