RESUMO
The quality of the studies was assessed using the Cochrane risk bias assessment tool and the results were analyzed using Review Manager 5.3 software. The evidence was also evaluated for its strength using GRADE. A total of 18 randomized controlled trials were included in the study, involving 1247 patients. The primary outcomes of this study included overall efficacy, effectiveness in treating specific symptoms, and the Traditional Chinese Medicine symptom score. The secondary outcomes included the levels of FT3, FT4, and TSH, the size of the thyroid gland, and any adverse events. The results of the meta-analysis showed that CHM combined with WM has a better curative effect and a more effective reduction in clinical symptoms than WM alone: comprehensive efficacy [OR = 4.83; 95% CI (3.45, 6.76)], syndrome efficacy [OR = 5.95; 95% CI (3.94, 8.99)], TCM symptom score SMD = -1.49; 95% CI (-1.86, -1.11)], FT3 [SMD = 0.59; 95% CI (0.48, 0.71)], FT4 [SMD = 0.59; 95% CI (0.48, 0.71)], TSH SMD = -0.97; 95% CI (-1.35, -0.58)], and thyroid volume SMD = -0.25; 95% CI (-0.34, 0.15)]. The incidence of adverse events between the groups was not significantly different [OR = 1.00; 95% CI (0.14, 7.27)]. Because of the effectiveness of CHM, we support using CHM to improve clinical efficacy in the treatment of HTH. The results of our research suggest that the use of Chinese Herbal Medicine (CHM) in combination with Western Medicine (WM) may result in improved clinical efficacy in the treatment of hypothyroidism (HTH) compared to using WM alone.
RESUMO
Mussel bioactive peptides have been viewed as mediators to maximize the high quality of life. In this study, the anti-aging activities of mussel oligopeptides were evaluated using H2O2-induced prematurely senescent MRC-5 fibroblasts. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry displayed that exposure to H2O2 led to the loss of cell viability and cell cycle arrest. In addition, H2O2 caused the elevation of senescence-associated-ß-galactosidase (SA-ß-gal) activity and formation of senescence-associated heterochromatin foci (SAHF). It was found that pretreatment with mussel oligopeptides could significantly attenuate these properties associated with cellular senescence. Mussel oligopeptides also led to the increase of glutathione (GSH) level and mitochondrial transmembrane potential (Δψm) recovery. In addition, mussel oligopeptides resulted in an improvement in transcriptional activity of peroxiredoxin 1 (Prx1), nicotinamide phosphoribosyltransferase (NAMPT) and sirtuin 1 (SIRT1). This study revealed that mussel oligopeptides could protect against cellular senescence induced by H2O2, and the effects were closely associated with redox cycle modulating and potentiating the SIRT1 pathway. These findings provide new insights into the beneficial role of mussel bioactive peptides on retarding senescence process.
