BACKGROUND:Studies have shown that ischemia-induced cellular autophagy dysfunction is a key factor in brain injury.Autophagy related genes 6(ATG6),microtubule-associated protein 1 light chain(LC3),p62,and other autophagy key proteins are involved in the processes such as neuronal axonal degeneration,death,and intracellular homeostasis maintenance,playing an important role in the recovery of neural function. OBJECTIVE:To review the research progress in the role of cellular autophagy in cerebral ischemic injury and the regulatory mechanism of traditional Chinese medicine. METHODS:The first author used"ischemic stroke,brain tissue injury,cellular autophagy,signaling pathways,traditional Chinese medicine compounds,terpenoids,alkaloids,flavonoids,saponins,lignans,phthalates"as Chinese and English keywords respectively to search for literature on autophagy,cerebral ischemic injury,and the regulatory mechanisms of traditional Chinese medicine from China National Knowledge Infrastructure(CNKI)and PubMed databases from January 2016 to February 2024.Literature that is not highly relevant,repetitive,or outdated was excluded.A total of 1 746 relevant literature were retrieved,and 92 articles were ultimately included. RESULTS AND CONCLUSION:Numerous studies have confirmed that autophagy plays an important role in cerebral ischemic injury.Moderate autophagy can promote cell survival,while excessive autophagy exacerbates brain injury.Traditional Chinese medicine can regulate the expression of autophagy related proteins,inhibit neuronal necrosis and apoptosis,and exert neuroprotective effects at different stages of cerebral ischemia by regulating signaling pathways such as PI3K/Akt/mTOR,AMPK-mTOR,and mitogen activated protein kinase.

BACKGROUND:Ferroptosis is a programmed cell death mode regulated by iron dependent lipid peroxidation,closely related to the occurrence,development,and outcome of ischemic brain injury.With the continuous deepening of research on ferroptosis in recent years,it has been found that Chinese herbal compounds and monomers can regulate ferroptosis by reducing iron overload,reducing the production of reactive oxygen species,and regulating lipid synthesis,to alleviate cerebral ischemic injury and promote neurological function recovery.OBJECTIVE:To explore the relationship between ferroptosis and ischemic brain injury,and the mechanism by which traditional Chinese medicine regulates ferroptosis in the treatment of ischemic brain injury.METHODS:Literature on ferroptosis and ischemic brain injury and the regulatory mechanism of traditional Chinese medicine published from January 2018 to May 2024 was searched in CNKI and PubMed databases.The search terms were"iron death,ischemic stroke,brain injury,reactive oxygen species,lipid metabolism,traditional Chinese medicine formulas,terpenes,flavonoids,phenols,alkaloids,phthalides"in Chinese and English,respectively.Irrelevant,duplicated or outdated literature was excluded.A total of 1 526 relevant literature were retrieved,and 87 articles were ultimately included.RESULTS AND CONCLUSION:Numerous experimental studies have confirmed that ferroptosis plays an important role in ischemic brain injury.Chinese medicine prescriptions can regulate ferroptosis through various approaches,for examples:total saponins of Panax notoginseng can regulate iron metabolism and inhibit lipid peroxidation;carvacrol inhibits neuronal ferroptosis by increasing glutathione peroxidase 4 expression;Chinese herbal compounds and monomeric active ingredients can regulate ferroptosis-related pathways,such as glutathione/glutathione peroxidase 4(GPX4),nuclear factor E2-related factor 2(Nrf2)/hemoglobin oxygenase 1(HO-1),ferric death inhibitory protein 1(FSP1)/CoQ10 and guanosine triphosphate cyclohydrolase 1(GCH1)/tetrahydrobiopterin(BH4),to reduce neuronal damage and death,and exert neuroprotective effects.

BACKGROUND:Research has shown that endoplasmic reticulum stress-induced autophagy of neurons in the ischemic penumbra is a key link in cerebral ischemia-reperfusion injury.Autophagy mediated by the dissociation and activation of endoplasmic reticulum transmembrane proteins PERK,IRE1 α,ATF6,and GRP78/BIP plays an important role in neuronal outcomes.Traditional Chinese medicine can regulate endoplasmic reticulum stress-autophagy,reduce neuronal damage or death,and exert neuroprotective effects.OBJECTIVE:To explore the role of endoplasmic reticulum stress-autophagy in cerebral ischemia-reperfusion injury and the research progress in the regulatory mechanisms of traditional Chinese medicine.METHODS:A literature retrieval was conducted in CNKI and PubMed for relevant literature related to endoplasmic reticulum stress,autophagy,cerebral ischemia-reperfusion injury,and regulation by traditional Chinese Medicine published from January 2015 to May 2024.The search terms were"cerebral ischemia-reperfusion injury,ischemic stroke,brain injury,endoplasmic reticulum stress,autophagy,traditional Chinese medicine,compounds,signaling pathways,saponins,polyphenols,alkaloids"in Chinese and English,respectively.Any literature that is inconsistent with the research content,outdated,or duplicated was excluded.A total of 1197 relevant literature were retrieved,and 71 articles were ultimately included.RESULTS AND CONCLUSION:(1)Numerous studies have suggested that endoplasmic reticulum stress-autophagy is closely related with cerebral ischemia-reperfusion injury.(2)The active ingredients and compound formulas of traditional Chinese medicine monomers can regulate the expression of endoplasmic reticulum stress-autophagy related proteins,alleviate neuronal damage,and exert neuroprotective effects by regulating signal pathways such as PERK-eIF2α-ATF4,IRE1α-ASK1-JNK,and IRE1α-XBP.

Objective:To evaluate the perceived level of home exercise behavior in elderly patients with ovarian cancer and analyze its influencing factors, so as to promote home exercise behavior of patients and improve the quality of life.Methods:A total of 227 elderly patients with ovarian cancer from January 1, 2021 to October 1, 2023 in the First Affiliated Hospital, School of Medicine, Zhejiang University were selected by convenience sampling method. A cross-sectional survey was conducted by General Information Questionnaire, Exercise Benefits/Barriers Scale (EBBS), Social Support Rating Scale (SSRS), General Self-efficacy Scale (GSES) and Brief Fatigue Inventory (BFI). The influencing factors on the perceived level of home exercise behavior in elderly patients with ovarian cancer were analyzed.Results:There were 227 elderly female patients with ovarian cancer, including 151 patients aged<70 years old and 76 patients aged ≥70 years old. The scores of EBBS, SSRS, GSES, BFI were (123.37±11.02), (37.68±7.44), (29.35±6.54), (5.82±2.01) points. The perception of exercise behavior was positively correlated with general self-efficacy and social support ( r=0.752, 0.901, both P<0.01), was negatively correlated with cancer-related fatigue ( r=-0.198, P<0.01). The results showed that general self-efficacy, social support, age≥70 years old, no spouse, not being informed of the benefits of exercise,fatigue due to moderate and severe cancer, duration of disease ≥12 months were the influencing factors ( t values were -4.56 - 4.46, all P<0.05). Conclusions:Elderly patients with ovarian cancer need to improve their perception level of home exercise behavior. In the formulation of home exercise behavior for elderly patients with ovarian cancer, education and cognition on the perceived benefits of home exercise behavior should be strengthened, and patients′ physical and mental status should be evaluated before exercise to actively reduce cancer-related fatigue. At the same time, the combination of family support can improve the perceived level of exercise behavior of elderly patients with ovarian cancer at home, so as to promote home exercise behavior of patients.

Mitochondrial autophagy is an important mechanism for maintaining cellular homeostasis,closely related to the occurrence and development of cerebral ischemic injury,and is an important way of neuronal death.In recent years,a large number of experimental studies have confirmed that traditional Chinese medicine has a significant effect on treating cerebral ischemic injury.Its advantages of multi-target,multi pathway,low toxicity and high efficiency have become an important component of the treatment of cerebral ischemic injury.Traditional Chinese medicine formulas and monomeric active ingredients such as Xiaoxuming decoction,Zishen Huoxue formula,flavonoids,alkaloids,etc.can regulate mitochondrial autophagy related signaling pathways and targets,inhibit neuronal autophagic death,alleviate pathological damage to brain tissue,and exert neuroprotective effects.This article analyzes the molecular mechanism of traditional Chinese medicine regulating mitochondrial autophagy in the treatment of cerebral ischemic injury from four aspects:an overview of mitochondrial autophagy,related signaling pathways,its relationship with cerebral ischemic injury,and the regulatory effects of traditional Chinese medicine.The aim is to provide ideas and references for future basic research and clinical treatment.
