Background: Myocardial injury is prone to occur during myocardial ischemia-reperfusion, which further causes adverse cardiac events. Cardiomyopeptide (CMP) has been found to protect the heart against ischemia-reperfusion injury. The present study will explore the molecular and signaling mechanisms associated with the therapeutic effects of CMP. ⋯ RNA-seq analysis results showed that PPARγ signaling pathway is a potential signaling pathway for CMP treatment of myocardial injury in rats. The experimental results showed that CMP can significantly up-regulate PPARγ expression in myocardial tissues, inhibit ischemia reperfusion-induced myocardial injury, and alleviate mitochondrial respiratory disorders. Conclusion: CMP can improve myocardial injury in rats by alleviating mitochondrial respiratory dysfunction and reducing myocardial tissue damage and inflammatory infiltration via the regulation of PPARγ signaling pathway.

Effective therapies for cognitive impairments induced by brain irradiation are currently lacking. This study investigated the therapeutic potential of hyperbaric oxygen therapy (HBOT) for radiation-induced brain injury in a randomized controlled experimental model using adult male Wistar rats. Adult male Wistar rats were divided into four experimental groups: 0 Gy whole brain radiotherapy (WBRT) with normal baric air (NBA) treatment, 0 Gy WBRT with HBOT, 10 Gy WBRT with NBA, and 10 Gy WBRT with HBOT. ⋯ In addition, HBOT prevented and reversed the increased apoptosis among newborn neural stem cells and neuroblasts caused by 10 Gy WBRT on 7 days. The findings suggest that WBRT disrupts neurogenesis and enhance microgliosis, apoptosis of neuronal progenitors, and lipid peroxidation in the dentate gyrus, potentially leading to cognitive deficits and neuronal death. HBOT may offer a protective effect against these cognitive impairments and their underlying mechanisms in adult male rats following WBRT.

Aminoglycosides and cisplatin drugs are extensively utilized for their high efficacy in treating various conditions in the clinic, however, their ototoxic side effects warrant significant attention. These drugs could penetrate the inner ear via specific channels or transporters, which not only affect the survival of hair cells but also induce the overproduction of reactive oxygen species. Currently, scientific research mainly addresses this issue through the downstream intervention of reactive oxygen species. ⋯ It is, therefore, imperative to investigate the regulatory role of the MET channel in the up-taking of ototoxic drugs, serving as a pivotal point for the development of preventative and therapeutic approaches. This review aims to highlight the mechanism of inhibition of ototoxic substances absorption by auditory hair cells, explore how to develop novel ear protection methods by targeting these channels and transporters, and provide a new perspective and strategy for addressing drug-induced ototoxicity. The approach to protecting hair cells by targeting these channels and transporters not only broadens our understanding of the underlying mechanisms of ototoxicity, but could also spur further research and progress in the field of auditory protection.

Objective: Chronic kidney disease (CKD) is a global health concern, and recent clinical evidence suggests the potential of traditional Chinese medicine (TCM) to slow CKD progression. This offers alternative strategies for CKD patients, mitigating risks related to polypharmacy and adverse drug reactions. Our self-controlled, prospective study aims to assess the impact of Eefooton (EFT), a TCM-based regimen, on kidney health in stage 3-5 CKD patients. ⋯ EFT decreased IS-induced expression of fibrosis-related proteins (α-smooth muscle actin) without affecting apoptosis-related proteins (Caspase 3). Conclusions: When combined with conventional CKD medications, EFT has shown effectiveness in enhancing kidney function in individuals with stage 3-5 CKD, with no reported safety concerns. The PARP-1 inhibition and anti-fibrosis properties of EFT present potential benefits in the context of CKD.

Background: The relationship between maternal thyroid-stimulating hormone (TSH), free thyroxine (FT4) and thyroid peroxidase antibody (TPOAb) status and hypertensive disorders of pregnancy (HDP) remains uncertain. Methods: This was a prospective cohort study based on the China Birth Cohort Study (CBCS). 36,256 women were included at 6 to 13+6 gestation from February 2018 to December 2020. Generalized linear mixed models were used to investigate the association between thyroid function and HDP/BP. ⋯ TSH and TPOAb positivity were significantly and positively associated with systolic pressure (TSH: β 0.02, 95% CI 0.07-0.26; TPOAb positivity: β 0.02, 95% CI 0.12-0.98) and diastolic pressure (TSH: β 0.02, 95% CI 0.02-0.17; TPOAb positivity: β 0.02, 95% CI 0.06-0.75). Subgroup analyses suggested that the association between TSH and diastolic pressure was stronger in those with BMI ≥ 25 kg/m2 (P = 0.014). Conclusions: Our founds suggest that high TSH and TPOAb positivity in the first trimester are associated with an increased risk of preeclampsia or eclampsia.
