Abstract

Abstract : Body constitution in traditional Chinese medicine (TCM) refers to the holistic and relatively durable state of an individual, based on the qi and blood assessment, and TCM syndrome is defined as the theoretical abstraction of disease-symptom profiles. The biological basis as related to mitochondria, which produce most of the cellular energy, has not been well studied. This study aimed to elucidate the association of mitochondrial function with TCM body constitution and cold syndrome. Body constitution and cold syndrome in TCM were assessed using the Constitution in Chinese Medicine Questionnaire (CCMQ). The mitochondrial function of peripheral leukocytes was evaluated based on oxygen consumption rate (OCR) and enzyme activity; OCR reflects mitochondrial activity and the capacity to produce adenosine triphosphate (ATP). Cellular adenosine nucleotides and malondialdehyde levels were determined using high-performance liquid chromatography to assess the potential bioenergetic mechanisms. A total of 283 adults participated in this study. Leukocytes from subjects with a balanced constitution had higher OCRs than those with unbalanced constitutions. Yang deficiency and cold syndrome also demonstrated lower energy metabolism, as indicated by reduced basal metabolic rate and cellular levels of ATP and malondialdehyde. Decreased mitochondrial enzyme activity has been observed in individuals with the cold syndrome. Unbalanced body constitutions in TCM impair mitochondrial function in leukocytes, which may contribute to the high disease susceptibility. Cold syndrome is characterized by reduced mitochondrial mass, which may explain its symptoms of low-energy metabolism and cold intolerance.
