The Correlation between Blood Stasis Constitution and Diseases： A Bibliometric Analysis of 135 Clinical Studies / 中医杂志

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.
