Background. Oxidative stress is an important mechanism of cerebral ischemia-reperfusion injury. Ferroptosis caused by iron overload after cerebral ischemia-reperfusion is considered a common cause of oxidative stress. Many recent studies have shown that electroacupuncture (EA) can regulate the expression of inflammatory factors, and the use of electroacupuncture preconditioning can produce a protective effect, which can reduce injury after cerebral ischemia and reperfusion. We aimed to assess whether EA could be used to reduce oxidative stress. Methods. The oxidative stress level of rats during the acute phase of cerebral ischemia and reperfusion was assessed with and without preconditioning with EA. Molecular biology methods were used to detect iron metabolism and oxidative stress-related proteins. Results. Rats that had EA preconditioning had lower infarct volumes than rats in the control group. Furthermore, western blot analysis showed that the expression of iron metabolism-related protein FPN-1 was higher in the intervention group than in the model group after reperfusion. In this regard, further investigation also demonstrated higher expression of glutathione and glutathione peroxidase-4, and lower reactive oxygen species values in the brain tissue of the EA group were compared with those of the control group rats. Conclusions. Electroacupuncture preconditioning can reduce oxidative stress after cerebral ischemia-reperfusion by regulating iron overload.

The aging process demonstrates notable differences between males and females, which are key factors in disease susceptibility and lifespan. The differences in sex chromosomes are fundamental to the presence of sex bias in organisms. Moreover, sex-specific epigenetic modifications and changes in sex hormone levels impact the development of immunity differently during embryonic development and beyond. Mitochondria, telomeres, homeodynamic space, and intestinal flora are intricately connected to sex differences in aging. These elements can have diverse effects on men and women, resulting in unique biological transformations and health outcomes as they grow older. This review explores how sex interacts with these elements and shapes the aging process.

In recent years, the efficacy of electroacupuncture (EA) pretreatment generating ischemic tolerance mimicking ischemic pretreatment (IP) has been continuously confirmed, which was first found in the brain and then in the heart. Furthermore, researchers have observed the intensive cardioprotection impact of EA pretreatment on patients undergoing percutaneous coronary intervention (PCI) and heart valve replacement, indicating that EA pretreatment tends to be a valuable and advantageous avenue for preventing acute myocardial ischemia/reperfusion (I/R) injury or treatment of ischemic heart disease (IHD). In reality, the heart protection mechanism of EA pretreatment is robust and pleiotropic, of which the regulatory molecular pathways are involved in multichannel, multilevel, and multitarget, including energy metabolism, inflammatory response, calcium overload, oxidative stress, autophagy, and apoptosis. Through a growing number of clinical tests and basic experiments with animal models, researchers progressively explored the optimal acupoints and parameters, where EA pretreatment induced acute and delayed ischemic tolerance for myocardial protection. Thereby, this article aims to collect the relevant evidence on EA pretreatment against myocardial ischemia/reperfusion injury (MIRI) and summarize the mechanism of cardioprotection of EA pretreatment to provide ideas and methods for further clinical applications.

Background: Post-stroke depression (PSD) is a prevalent complication of stroke that adversely affects patient outcomes. The etiology of PSD is complex, and no universally effective treatment exists. Acupuncture, with its historical use, combined with music therapy, presents a novel approach for PSD treatment. This study aims to systematically evaluate the clinical efficacy of combining acupuncture with music therapy for PSD through a meta-analysis. Methods: We systematically searched both Chinese and English literature in PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and the Chinese Science and Technology Periodical Database (VIP Database) for randomized controlled trials evaluating acupuncture combined with music therapy for PSD. Two independent evaluators conducted quality assessments and data extraction. Statistical analyses were performed using RevMan 5.4 and Stata 18.0 software. Results: This article contains 11 studies, involving a total of 698 patients. The results of the meta-analysis showed that, compared with the control group, the test group showed significant improvement on multiple outcome measures: HAMD score [mean difference (MD) = ‐3.18, 95% confidence interval (CI) (‐3.61, ‐2.76), P < .00001], Self-Rating Depression Scale score [MD = ‐5.12, 95% CI (‐6.61, ‐3.63), P < .00001], Pittsburgh sleep quality index score [MD = ‐2.40, 95% CI (‐2.96, ‐1.84), P < .00001], BI score [MD = 14.16, 95% CI (4.37, 23.94), P = .005] were all significantly lower, significantly higher effectiveness [risk ratio = 1.21, 95% CI (1.11, 1.33), P < .0001]. These differences were also statistically significant. Conclusion: The use of acupuncture combined with music therapy is effective in reducing depression in PSD patients.
