ABSTRACT
ObjectiveTo explore the correlation between blood stasis constitution (BSC) and diseases based on constitution literature involving “constitution-diseases correlation”. MethodsA comprehensive search was conducted on six Chinese and English electronic databases including CNKI, Wanfang, VIP, SinoMed, PubMed and Embase to find all clinical researches on the correlation between constitution and diseases using the Classification and Identification of Chinese Medicine Constitution standard from April 1st, 2009 to December 31st, 2022, and the participants of the research were BSC related. By analyzing the characteristics of the literature, such as authors, publication institutes, participants, and results, the disease with the highest proportion of BSC distribution or BSC as their risk factors or protective factors were summarized to explore the correlation between BSC and diseases. ResultsTotally 135 clinical studies on diseases highly related to BSC were included, with a total sample size of 71 172 cases.There were 27 keywords in the articles appeared more than 3 times, including the elderly, lumbar disc herniation, coronary heart disease, cardiovascular disease, and endometriosis. In the author's clustering, included studis were mainly from Shenzhen Hospital of Beijing University of Chinese Medicine, Second Affiliated Hospital of Guangzhou University of Chinese Medicine, and Wenzhou Central Hospital. In terms of blood stasis related diseases, 81 studies showed that BSC was the most common type of constitution in the study population, involving 48 disease or morbid states. The diseases and median proportions of BSC with reported literature ≥3 included coronary heart disease (28.8%), endometriosis (31.3%), neurocognitive impairment (26.4%), lumbar disc herniation (26.0%), ischemic stroke (25.0%), adenomyosis (34.7%), and endometrial polyps (25.0%). Fifty-eight studies found that BSC was a risk factor for disease occurrence,and these diseases reported more than 3 times included hypertension (median OR = 2.956), type 2 diabetes (median OR = 3.436),osteoporosis (median OR = 5.171), sudden deafness (median OR = 3.827) and endometriosis (median OR = 5.412). One study indicated BSC as the protective factor of lateral growth tumor of large intestine (median OR = 0.161). ConclusionBSC is closely related to circulatory system diseases, urogenital system diseases, and musculoskeletal system diseases.
ABSTRACT
Objective To dig the correlation between genes and four TCM constitutions (phlegm-dampness, blood stasis, allergy, and dampness-heat); To analyze microscopic mechanism of constitution formed and constitution-disease correlation; To provide biological basis for TCM constitution classification and constitution-disease correlation theory. Methods Literature about TCM constitutions and gene expressions in CNKI and Wanfang Database were retrieved by computers from the establishment of database to 31, December 2016. Differentially expressed genes of four TCM constitutions were collected, and DAVID database was used for enrichment analysis, including gene tissue enrichment analysis, disease analysis, GO analysis, and pathway analysis. The results of DAVID database analysis were downloaded and analyzed. Results Four TCM constitutions had differences in gene level, and each constitution had the specificity in significantly enriched gene function, activity, pathways, related diseases, and expression locations. Different patterns of gene expression led to the constitution differences in disease susceptibility and tendency. Conclusion The essence of TCM constitution formation is the change of gene expression patterns, and the pathological changes are also caused by the change.
