Abstract:
ObjectiveTo clarify the protective effect of Danlou tablet, a representative traditional Chinese medicine of the stagnation of phlegm and blood stasis co-treatment method, on vascular endothelial function in patients with atherosclerosis (AS). MethodsA randomized controlled trial was conducted. From September 2023 to November 2023, a total of 72 patients who were diagnosed at Guang'anmen Hospital, China Academy of Chinese Medical Sciences and met the inclusion and exclusion criteria for carotid atherosclerosis (CAS) combined with coronary atherosclerotic heart disease (CHD) and stable angina pectoris (SAP) were enrolled. The patients were randomly divided into a control group (receiving conventional Western medicine treatment) and an observation group (receiving Danlou tablet combined with conventional Western medicine treatment), with 36 cases in each group. The intervention lasted for 12 weeks. The frequency of angina pectoris attacks was recorded to evaluate the clinical efficacy of Danlou tablet. Peripheral blood samples were collected from patients, and the expression levels of serum endothelial injury markers before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA). The nitrate reductase method was employed to evaluate the protective effect of Danlou tablet on vascular function. The expression levels of serum inflammatory factors and lipoproteins were determined by ELISA and an automatic biochemical analyzer (dynamic timed scatter turbidimetry and enzymatic method) to assess the anti-inflammatory and lipid-regulating effects of Danlou tablet. ResultsIn terms of angina pectoris attacks, compared with that in the control group, the frequency of attacks in the observation group was reduced (P<0.05). In terms of endothelial injury markers, compared with the levels before treatment within the same group, the levels of endothelin-1 (ET-1), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) in the peripheral blood of the observation group were decreased (P<0.05), while the levels of nitric oxide (NO) and vascular endothelial growth factor (VEGF) were increased (P<0.05). Compared with the control group after treatment, the differences in ET-1, NO, ICAM-1, and VCAM-1 were significant (P<0.05). In terms of serum inflammatory factors, after treatment, the interleukin-6 (IL-6) level in the observation group was decreased significantly (P<0.05). Compared with the control group after treatment, the IL-6 level in the observation group was decreased significantly (P<0.01). In terms of serum lipoproteins, after treatment, the level of low-density lipoprotein cholesterol (LDL-C) in the observation group was decreased (P<0.05). After treatment, the level of high-density lipoprotein cholesterol (HDL-C) in the observation group was significantly higher than that in the control group (P<0.05). In terms of safety evaluation, no serious adverse events occurred in either group during the intervention period. ConclusionDanlou tablet applied to patients with CAS combined with CHD can improve endothelial function, reduce inflammatory indicators, alleviate symptoms, improve the quality of life of patients, and demonstrate good safety.
