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.

Objective:To systematically synthesize the real experiences of women who have undergone emergency cesarean sections, providing evidence-based insights to inform the development of personalized care strategies.Methods:A comprehensive literature search was conducted across PubMed, Web of Science, Embase, CINAHL, Cochrane Library, PsycINFO, ProQuest, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc for qualitative and mixed-methods studies related to the psychological experiences of women who underwent emergency cesarean sections. The search covered all publications up to January 31, 2025. The methodological quality of included studies was appraised using the Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The results were integrated using an aggregative synthesis approach.Results:A total of 16 studies were included, from which 78 findings were extracted and grouped into nine new categories. These were further synthesized into three overarching themes: shift in birth plan and emergence of dynamic emotional responses; desire for diversified external support and encouragement; emotional investment and character growth.Conclusions:Women undergoing emergency cesarean sections commonly experience intense negative emotions. It is essential for healthcare providers and family members to pay close attention to the physical and psychological well-being of postpartum women, offer timely emotional support, and help them recover from psychological trauma, thereby promoting maternal mental and physical health.

Objective:To evaluate the effect of preoperative neoadjuvant chemotherapy on rocuronium bromide-induced neuromuscular blockade in patients undergoing radical resection of gastrointestinal tumors.Methods:In this retrospective cohort study, the medical records from patients pathologically diagnosed with gastrointestinal tumors (stageⅡ or Ⅲ) and underwent elective radical tumour resection under general anaesthesia, aged 43-74 yr, with a body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ at Shaanxi Provincial People′s Hospital from November 2021 to November 2022, were collected. The patients were divided into 2 groups based on whether preoperative neoadjuvant chemotherapy was performed: non-chemotherapy group and chemotherapy group. Non-chemotherapy group did not receive neoadjuvant chemotherapy before surgery and underwent direct surgery without receiving neoadjuvant chemotherapy. Chemotherapy group received 4 weeks of chemotherapy with FOLFOX (5-fluorouracil, leucovorin, oxaliplatin), XELOX (capecitabine + oxaliplatin) or SOX (oxaliplatin + tegio) the three regimens before surgery. The neuromuscular monitoring was initiated after induction of intravenous anaesthesia, and rocuronium bromide 0.6 mg/kg was intravenously injected when the train-of-four ratio stabilized at 90%-110%. Mechanical ventilation was performed after endotracheal intubation when the train-of-four count was 0. When T 1 began to recover, rocuronium 0.2 mg/kg was intravenously injected, and rocuronium was intermittently injected during operation to maintain muscle relaxation. The onset time, complete muscle relaxation time, recovery index, 90% recovery index, maintenance time and consumption of rocuronium were recorded. Results:A total of 40 patients were finally included, with 20 in each group. Compared with non-chemotherapy group, the onset time was significantly prolonged, the recovery index, 90% recovery index and consumption of rocuronium were increased, the time for complete muscle relaxation was shortened ( P<0.05), and no significant change was found in the maintenance time of muscle relaxation in chemotherapy group ( P>0.05). Conclusions:Preoperative neoadjuvant chemotherapy can prolong the onset and recovery time of rocuronium, shorten the time to complete muscle relaxation and increase the consumption in patients undergoing radical resection of gastrointestinal tumors.

Objective:To develop and evaluate the reliability and validity of a questionnaire for assessing long-term care needs among community-dwelling older adults.Methods:Guided by the International Classification of Functioning, Disability and Health (ICF), an initial item pool for the questionnaire was constructed based on literature review, descriptive qualitative research, and expert consultations. The draft questionnaire was formulated by transforming the established indicator system for long-term care needs into survey items. Using stratified sampling, a total of 622 older adults from community settings in Changsha were surveyed between June and August 2021. Item analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and reliability testing were conducted.Results:The final questionnaire consists of three subscales (mental function, physical function, and activity and participation), comprising a total of 47 items. The item-level content validity index ( I- CVI) ranged from 0.830 to 1.000, and the scale-level content validity index ( S- CVI) was 0.915. EFA results showed that the extracted factors aligned well with the predefined dimensions after adjustment, with factor loadings exceeding 0.600 and cumulative variance contributions exceeding 70.000% for all subscales. CFA results indicated good model fit across all subscales and the overall questionnaire, confirming stable structural validity. The Cronbach's α coefficients ranged from 0.877 to 0.970, and test-retest reliability coefficients ranged from 0.901 to 0.957. Conclusions:The long-term care needs assessment questionnaire for community-dwelling older adults demonstrates strong reliability and validity, and can serve as a reliable tool for evaluating long-term care needs in this population.

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.

Objective:The greater tuberosity angle(GTA)and critical shoulder angle(CSA)are commonly referred to as radiographic markers which were used to described morphology of the greater tu-berosity and acromion respectively.At present,most international studies focus on the correlation be-tween the above two parameters and rotator cuff tears(RCTs),and their diagnostic value and risk assess-ment.This study attempts to find out the trend of GTA and CSA changes and risk threshold of RCTs,as well as the protective factors and risk factors.Methods:In this study,130 individuals from May 2019 to December 2020 were recruited.According to Southern California Orthopedic Institute(SCOI)classifica-tion,the individuals were divided into four groups retrospectively:Group A,negative control group;Group B,partial tears(articular side);Group C,partial tears(bursal side);Group D,full-thickness tears.GTA and CSA were measured respectively on true anteroposterior position X-ray of shoulder with arm in neutral rotation and performed by the same trained technician team in single-blind.The correla-tions between RCTs and relevant factors were analyzed.Results:According to the area under the receiver operating characteristic curve(AUC),GTA and CSA of RCTs(Groups B,C and D)were 0.736 and 0.673 with 95％confidence interval(CI),the cut-off value of GTA and CSA of RCTs were 70.5° and 39.5° respectively.Comparing with the control group,RCTs groups had significant statistical differences in age and body mass index(BMI)(P＜0.05),especially the full-thickness RCTs(Group D),which was older than Groups A,B and C(P＜0.05,cut-off value:56.5 years old)and shorter than Groups A and B(P＜0.05,cut-off value:1.58 m).Analyzed from scatter plot and regression analysis,there was no linear correlation between GTA and CSA.There were no significant differences in gender,dominant shoulders and smoking between the RCTs groups and the control group(P＞0.05).Conclusion:Larger GTA(＞70.5°)and CSA(＞39.5°)would be highly predictive in diagnosing RCTs without linear cor-relation,and GTA has a higher diagnostic value in contrast.Subacromial impingement and shoulder de-generation occurred before RCTs.Patients with age＞56.5 years and height＜1.58 m were more likely to develop disease of full-thickness RCTs and no statistic differences in weight and BMI.Gender,domi-nant shoulder and smoking were neither risk factors nor protective factors.
