Shugan Jieyu capsule effects on peripheral blood micro-124, micro-132, and brain-derived neurotrophic factor in patients with mild to moderate depression.

Abstract

Background: To assess the effectiveness of Shugan Jieyu capsules on peripheral blood miR-124, miR-132, and brain-derived neurotrophic factor (BDNF) levels in patients with mild to moderate depression following coronary artery intervention [percutaneous coronary intervention (PCI)] for coronary heart disease.

Aim: To evaluate the therapeutic efficacy of Shugan Jieyu capsules and their effects on the peripheral blood levels of miR-124, miR-132, and BDNF in patients with mild to moderate depression following PCI for coronary heart disease.

Methods: Patients with mild-to-moderate depression of the liver-qi stagnation type after PCI for coronary heart disease at the 305^th Hospital of the People's Liberation Army were enrolled from June 2022 to November 2023 and randomly assigned to two groups: Experimental (treated with Shugan Jieyu capsules) and control (treated with escitalopram oxalate tablets). This study compared the antidepressant effects of these treatments using 17-item Hamilton Rating Scale for Depression (HAMD-17) scores, metabolic equivalents, low-density lipoprotein cholesterol, BDNF, high-sensitivity C-reactive protein levels, miR-124 and miR-132 levels, distribution of immune-related lymphocyte subsets, and traditional Chinese medicine syndrome scores before and after 6 weeks of treatment.

Results: No significant difference was observed in any index between the two groups before treatment (P > 0.05). After treatment, the total efficacy rates were 93.33% and 90.00% in the experimental and control groups, respectively. Experimental group had significantly lower scores for the main and secondary syndromes compared to the control group (P < 0.05). No significant difference was observed in the metabolic equivalents between the two groups before and after treatment (P > 0.05). The levels of low-density lipoprotein cholesterol, high-sensitivity C-reactive protein, and miR-132 were significantly lower, whereas those of miR-124, BDNF, CD3+T lymphocytes, CD3+CD4+T helper lymphocytes, and CD3+CD4+/CD3+CD8+ cells were significantly higher in the experimental group compared to the control group (P < 0.05). The incidence of adverse reactions during experimental group was significantly lower than that in control group (P < 0.05).

Conclusion: Shugan Jieyu capsules have good efficacy in patients with mild-to-moderate depression after PCI, and its mechanism may contribute to the regulation of miR-124, miR-132, BDNF levels, and lymphoid immune cells.
