RESUMO
Objective: To evaluate the efficacy of ginseng-containing traditional Chinese medicine (TCM) for acute decompensated heart failure (ADHF). Methods: Seven databases were included from establishment until 10 July 2022. Pooled data were analyzed with random-effects model. The risk of bias was measured by the risk of bias tool for randomized trials (RoB 2). Modified Jadad scale score was used to assess the quality of including studies. The meta-analysis was performed with RevMan 5.3. Trial sequential analysis was assessed to avoid type I errors. We have registered our protocol in PROSPERO (CRD42021267742). Results: Twenty-eight articles were included. The results demonstrated that compared with conventional western therapy (WT), ginseng-containing TCM combined with WT further improved clinical efficacy (RR: 1.25, 95% CI: 1.20-1.29, p < 0.00001, I2 = 8%), left ventricular ejection fraction (LVEF) (MD: 5.80, 95% CI: 4.86-6.74, p < 0.00001, I2 = 89%), stroke volume (MD: 13.80, 95% CI: 12.66-14.95, p < 0.00001, I2 = 93%), 6-min walk test (MD: 53.03, 95% CI: 20.76-85.29, p = 0.001, I2 = 97%), decreased 6-month rehospitalization (RR: 0.44, 95% CI: 0.18-1.11, p = 0.08, I2 = 0%), brain natriuretic peptide (MD: 188.12, 95% CI: 248.13 to -128.11, p < 0.00001, I2 = 94%), N-terminal pro-B-type natriuretic peptide (MD = -503.29; 95% CI: 753.18 to -253.40, p < 0.0001, I2 = 89%) and Minnesota living heart failure questionnaire scores (MD: 9.68, 95% CI: 13.67 to -5.70, p < 0.00001, I2 = 83%). The ROB2 assessment and modified Jaded scores showed most studies included were with some concerns. Conclusion: Compared with WT alone, ginseng-containing TCM is a possible way to benefit ADHF patients. However, limited by the quality of including trials, more high-quality studies are needed to provide reliable evidence.
RESUMO
CONTEXT: HuoXue QianYang QuTan Recipe (HQQR) is used to manage hypertension and cardiac remodelling, but the mechanism is elusive. OBJECTIVE: To determine the mechanism of HQQR on obesity hypertension (OBH)-related myocardial fibrosis. MATERIALS AND METHODS: OBH models were prepared using spontaneously hypertensive rats (SHRs) and divided (n = 6) into saline, low-dose (19.35 g/kg/d) HQQR, high-dose (38.7 g/kg/d) HQQR, and valsartan (30 mg/kg/d) groups for 10 weeks. Systolic blood pressure (SBP), and Lee's index were measured. Heart tissues were examined by histology. HQQR's effects were examined on cardiac fibroblasts (CFs) stimulated with angiotensin II and treated with HQQR, a caspase-1 inhibitor, siNLRP3, and oeNLRP3. RESULTS: HQQR(H) reduced SBP (201.67 ± 21.00 vs. 169.00 ± 10.00), Lee's index (321.50 ± 3.87 vs. 314.58 ± 3.88), and left ventricle mass index (3.26 ± 0.27 vs. 2.71 ± 0.12) in vivo. HQQR reduced percentage of fibrosis area (18.99 ± 3.90 vs. 13.37 ± 3.39), IL-1ß (10.07 ± 1.16 vs. 5.35 ± 1.29), and inhibited activation of NLRP3/caspase-1/IL-1ß pathway. HQQR also inhibiting the proliferation (1.09 ± 0.02 vs. 0.84 ± 0.01), fibroblast to myofibroblast transition (14.74 ± 3.39 vs. 3.97 ± 0.53), and collagen deposition (Col I; 0.50 ± 0.02 vs. 0.27 ± 0.05 and Col III; 0.48 ± 0.21 vs. 0.26 ± 0.11) with different concentrations selected based on IC50 in vitro (all ps < 0.05). NLRP3 interference further confirmed HQQR inhibiting NLRP3 inflammasome signalling. CONCLUSION: HQQR blunted cardiac fibrosis development in OBH and suppressed CFs proliferation by directly interfering with the NLRP3/caspase-1/IL-1ß pathway.
