The impact of "long COVID" on menstruation in Chinese female college students and the intervention of acupuncture.

This study aimed to explore the potential application value of acupuncture in alleviating the impact of long COVID on women's menstrual cycles, by investigating the occurrence of long COVID among female college students, its effects on menstruation, and the intervention of acupuncture. This cross-sectional study surveyed female college students with a history of coronavirus disease 2019 (COVID-19) before April 10, 2023. A questionnaire was used to analyze demographic characteristics, post-COVID sequelaes, duration of symptoms, and treatments received during that period. Among the 731 participants enrolled in the survey, 468 were female undergraduate students who met the analysis criteria. Among them, 85 individuals fit the definition of "Long COVID" (18.16%). Within the group of patients with long COVID, 69 individuals experienced changes in their overall menstrual patterns compared to the 6 months prior to contracting the novel coronavirus (81.18%). Additionally, 17 individuals opted for acupuncture treatment following the onset of COVID-19 (20.00%), which resulted in less impact on their menstrual cycle (41.18% vs 64.71% without receiving acupuncture, OR = 2.62), menstrual period duration (41.18% vs 64.71%, OR = 2.62), menstrual flow (47.06% vs 69.18%, OR = 2.52), and the color of menstrual blood (41.18% vs 63.24%, OR = 2.46) among these patients. Long COVID had a certain impact on menstruation. Acupuncture potentially alleviates the clinical symptoms of long COVID and reduces its impact on women's menstrual cycle, thus having potential therapeutic value in the treatment of long COVID.

Acupuncture for autophagy in animal models of middle cerebral artery occlusion: A systematic review and meta-analysis protocol.

INTRODUCTION: Ischemic stroke has high morbidity, disability and mortality rates. The effective treatments recommended by guideline have considerable limitations due to their strict range of adaptation and narrow time window. Acupuncture is an effective and safe treatment for ischemic stroke, and the mechanism may be related to autophagy. In this systematic review, we aim to summarize and evaluate the evidence of autophagy in acupuncture therapy for animal models of middle cerebral artery occlusion (MCAO). METHODS: Publications will be retrieved from the MEDLINE, Embase, Cochrane Library, Web of Science, CNKI, CBM, CVIP and Wanfang databases. We will include animal experimental studies of acupuncture for MCAO, and the control group will receive placebo/sham acupuncture or no treatment after model establishment. Outcome measures must include autophagy and will include neurologic scores and/or infarct size. The Systematic Review Center for Laboratory animal Experimentation (SYRCLE) risk of bias tool will be used to assess the risk of bias. A meta-analysis will be performed if the included studies are sufficiently homogenous. Subgroup analyses will be conducted according to different intervention types and different types of outcomes. Sensitivity analyses will also performed to explore the heterogeneity and to assess the stability of the results. Publication bias will be assessed by funnel plots. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system will be applied to evaluate the quality of evidence in this systematic review. DISCUSSION: The results of this study may help to explain autophagy in acupuncture therapy for ischemic stroke. The limitation of this review is that all included studies will be retrieved from Chinese or English medical databases due to language barriers.
