With the increasing incidence of diabetes mellitus in recent years, cardiomyopathy caused by diabetes mellitus has aroused wide concern and this disease is characterized by high insidiousness and high mortality. The early pathological changes of diabetic cardiomyopathy (DCM) are mitochondrial structural disorders and loss of myocardial metabolic flexibility. The turbulence of mitochondrial quality control (MQC) is a key mechanism leading to the accumulation of damaged mitochondria and loss of myocardial metabolic flexibility, which, together with elevated levels of oxidative stress and inflammation, trigger changes in myocardial structure and function. Qi deficiency and stagnation is caused by the loss of healthy Qi, and the dysfunction of Qi transformation results in the accumulation of pathogenic Qi, which further triggers injuries. According to the theory of traditional Chinese medicine (TCM), DCM is rooted in Qi deficiency of the heart, spleen, and kidney. The dysfunction of Qi transformation leads to the generation and lingering of turbidity, stasis, and toxin in the nutrient-blood and vessels, ultimately damaging the heart. Therefore, Qi deficiency and stagnation is the basic pathologic mechanism of DCM. Mitochondria, similar to Qi in substance and function, are one of the microscopic manifestations of Qi. The role of MQC is consistent with the defense function of Qi. In the case of MQC turbulence, mitochondrial structure and function are impaired. As a result, Qi deficiency gradually emerges and triggers pathological changes, which make it difficult to remove the stagnant pathogenic factor and aggravates the MQC turbulence. Ultimately, DCM occurs. Targeting MQC to treat DCM has become the focus of current research, and TCM has the advantages of acting on multiple targets and pathways. According to the pathogenesis of Qi deficiency and stagnation in DCM and the modern medical understanding of MQC, the treatment should follow the principles of invigorating healthy Qi, tonifying deficiency, and regulating Qi movement. This paper aims to provide ideas for formulating prescriptions and clinical references for the TCM treatment of DCM by targeting MQC.

ObjectiveTo observe the clinical efficacy of the Modified Tongmai Anshen Formula (通脉安神方加减, MTAF) in the treatment of stable angina pectoris (SAP) with sleep disorders. MethodsA total of 148 patients suffering from SAP with sleep disorder were included and randomly divided into control group and treatment group, with 74 patients in each group. The control group received conventional western medicine, and the treatment group additionally received MTAF (1 dose per day), both for 4 weeks. The changes in angina pectoris symptoms, traditional Chinese medicine (TCM) syndromes, sleep quality, quality of life, serological indicators including serum intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), brain-derived nerve growth factor (BDNF) and tyrosine kinase receptor B (TrkB) were compared between groups before and after treatment, and the safety was evaluated. ResultsIn the treatment group and the control group, the total effective rates of TCM syndromes(82.43% vs 52.70%), angina pectoris (79.73% vs 64.86%) and sleep (89.19% vs 68.92%) showing significant difference (P<0.001). After treatment, the total TCM syndrome score, primary symptom score, secondary symptom score, and secondary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, PSQI total score and each item score were all significantly reduced in both groups, while the SF-36 single item score significantly increased (P<0.05). The total TCM syndromes and primary symptom scores, secon-dary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, time to fall asleep, sleep quality, hypnotic medication, sleep disturbance, daytime dysfunction score and PSQI total score were significantly lower in the treatment group than those in the control group after treatment (P<0.05), while the somatic pain, general health status, social functioning, emotional functioning, mental health, and health change were significantly higher in the treatment group (P<0.05). After treatment, ICAM-1 and VCAM-1 level significantly decreased (P<0.05), and BDNF and TrkB levels increased (P<0.05) in the treatment group, while BDNF level significantly decreased in the control group (P<0.05). The TrkB level was significantly higher in the treatment group compared to the control group after treatment (P<0.05). A total of four adverse events occurred during the treatment, none of which were considered to be related to this study. ConclusionMTAF can significantly improve angina pectoris symptoms, TCM syndromes, sleep quality and quality of life in patients suffering from SAP with sleep disorders, the mechanism of which may be related to the protection of vascular endothelial function and central neurons.
