Acupuncture improves perimenopausal depression via a mechanism involving activation of the phosphatidylinositol 3-kinase/serine-threonine protein kinase/mechanistic target of rapamycin pathway in a rat model.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPerimenopausal depression (PMD), a psychiatric disorder triggered by declining ovarian function before menopause, remains poorly understood in terms of therapeutic mechanisms. While acupuncture has demonstrated efficacy in alleviating PMD symptoms, its molecular basis requires further exploration. This study aimed to investigate whether acupuncture ameliorates PMD by modulating phosphatidylinositol 3-kinase (PI3K)/serine-threonine protein kinase (AKT)/mammalian target of rapamycin (mTOR) signaling in a rat model.
methodsThe female SD rats were randomly assigned to four groups: model, blank, acupuncture, and Western medicine, with each group consisting of six rats. The acupuncture group received acupuncture at the Baihui (GU20), Shenshu (BL23), Ganshu (BL18), and Sanyinjiao points for 28 consecutive sessions over 4 weeks. A PMD rat model was established through ovariectomy (OVX) combined with chronic unpredictable mild stress. Depression-related behaviors were measured through the forced swimming test, sucrose preference test, and open field test. The levels of estrogen (E2), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and gonadotropin-releasing hormone (GnRH) in serum were determined through ELISA. The expression of PI3K, AKT, and mTOR in the hippocampal Cornu Ammonis 1 (CA1) region was analyzed by reverse transcription quantitative PCR and Western blotting.
resultsAcupuncture markedly attenuated depression-like behaviors and hippocampal pathology in PMD rats. It restored hormonal balance by elevating serum E2 while suppressing FSH, LH, and GnRH. At the molecular scale, acupuncture enhanced the expression of both mRNA and proteins of PI3K, AKT, and mTOR in the hippocampus CA1 region.
conclusionAcupuncture alleviates PMD through dual regulation of sex hormone homeostasis and activation of the PI3K/AKT/mTOR pathway, suggesting a potential mechanism for its antidepressant effects in perimenopause.
