Objective To detect the content of 5'-tRF-GlyGCC in peripheral blood and explore its applica-tion value in the early diagnosis of colorectal cancer(CRC).Methods Peripheral blood samples were randomly collected from 99 CRC patients,11 patients with enteritis,17 patients with colorectal polyps and 99 healthy indi-viduals in the same period at the Affiliated Hospital of Guizhou Medical University.The content of 5'-tRF-GlyGCC in total RNA of peripheral blood was detected by fluorescence RT-PCR.The receiver operating characteristic curve(ROC)was established to analyze the value of 5'-tRF-GlyGCC content in the early diagnosis of CRC and to explore the relationship between its content and the clinical and pathological characteristics of CRC patients.Results The content of 5'-tRF-GlyGCC in the peripheral blood of CRC patients and colorectal polyp patients was significantly higher than that of healthy individuals and patients with enteritis,and the differences were statistically significant(P<0.05).The area under the curve(AUC)of 5'-tRF-GlyGCC for diagnosing CRC was 0.817(95%CI:0.763～0.871),with a diagnostic sensitivity of 56.7%and a specificity of 99.9%.The content of 5'-tRF-GlyGCC in peripheral blood was significantly positively correlated with the levels of CEA and CA19-9 in CRC patients.Conclusion The detection of 5'-tRF-GlyGCC in peripheral blood has a high application value in the early diagnosis of CRC and can be used for clinical reference and research.

Central nervous system(CNS)degenerative disorders refer to a spectrum of pathological alterations triggered by struc-tural damage to cerebral neural tissues,clinically manifested as diverse neurological dysfunction syndromes,including multiple sclerosis(MS),neurodegenerative diseases(NDs),and ische-mic stroke.The hallmark pathological features of these disorders involve irreversible neuronal damage and decompensation of functional neural networks,ultimately leading to progressive neurological deficits.Notably,with the accelerating global popu-lation aging,the incidence of these diseases has surged signifi-cantly.According to WHO statistics,they now rank among the top three global causes of disability and mortality.Current re-search has confirmed that the pathogenesis of CNS degenerative disorders exhibits high heterogeneity,encompassing multifaceted pathophysiological processes such as genetic predisposition,oxi-dative stress,protein misfolding,and metabolic dysregulation.This intricate pathogenic network not only complicates clinical differential diagnosis but also poses substantial challenges to the development of precision therapeutic strategies.Importantly,re-cent studies have revealed that mitochondrial homeostasis disrup-tion-induced inflammatory cascades(termed mitochondrial in-flammation)play a pivotal regulatory role in neurodegenerative progression.Key molecular mechanisms include impaired mito-phagy,aberrant mitochondrial DNA(mtDNA)release and NL-RP3 inflammasome activation.This review systematically deci-phers the molecular regulatory network of mitochondrial inflam-mation,with a focus on its biological effects in critical pathologi-cal events such as blood-brain barrier disruption,microglial hy-peractivation and neuronal apoptosis.The overarching aim is to provide a theoretical foundation for developing innovative thera-peutic strategies targeting mitochondrial homeostasis restoration.

Objective:To construct an evaluation index system for rural order-oriented general practice residents based on Entrustable Professional Activities (EPAs) and conduct an empirical analysis. ?Methods:A mixed-methods study design was adopted (November 2022-April 2023). The preliminary draft of the index system was developed through literature review and group discussions, then refined and improved via two rounds of expert consultation using the Delphi method. The analytic hierarchy process (AHP) was applied to determine the weight of each index. Meanwhile, questionnaires were distributed to 181 participants, including general practitioners from general hospitals, general practitioners from community hospitals, and general practice residents. The scores of the three groups regarding the importance and feasibility of the indices were compared. Ten general practitioners of the above three types were selected for semi-structured interviews on their cognitive and practical aspects of the system. ?Results:The positive coefficients of the two rounds of expert consultation were 16/17 and 16/16, respectively. The expert authority degree was >0.70, and the test of coordination coefficient was statistically significant ( P<0.05). Finally, an index system consisting of 20 first-level indices and 56 second-level indices was established. In terms of weight, among the first-level indices,"EPA1: Information Acquisition"had the highest weight (0.11), while"EPA12: Clinical Research"had the lowest (0.02). Among the second-level indices, "Medical History Taking" and "Physical Examination" under EPA1 had the highest weight (both 0.056), while "Healthcare for Patients with Severe Mental Illness" and "Healthcare for Disabled and Handicapped Populations" under EPA15 had the lowest (both 0.003). The 181 participants gave scores ranging from 4.49 to 4.92 for the importance of the 20 first-level indices and from 4.16 to 4.81 for their feasibility. Only for" EPA19: Common Diseases in Primary Care and Health Management", the feasibility score given by general practitioners from community hospitals was higher than that from general hospitals ( t=2.157, P=0.032); no statistically significant differences were observed among the groups for the other indices ( P>0.05).The interview results showed that general practitioners have a relatively high level of recognition for this system, but there is still room for improvement in its practical application.? Conclusions:The evaluation index system for rural order-oriented general practice residents constructed based on EPAs has high reliability, and it is consistently recognized by different types of general practitioners. It can provide a reference for the cultivation of post competency of this group.?

Major depressive disorder (MDD) is one of the most disabling illnesses, and approximately one-third of patients with MDD fail to show significant improvement after multiple courses of antidepressants, eventually progressing to treatment-resistant depression (TRD), a more severe and complex subtype that is difficult to treat. Obsessive-compulsive disorder (OCD) is a type of mental disorder characterized by repetitive obsessions and/or compulsive behaviors, and the high rate of comorbidity with other psychiatric disorders has been identified as a hallmark feature of OCD. In particular, OCD frequently co-occurs with MDD, and when these two conditions overlap, the resulting comorbidity is characterized by more severe symptoms and an increased risk of suicide. Magnetic seizure therapy (MST) is a novel, non-invasive neuromodulation technique that is safe and effective in the treatment of TRD with less cognitive impairment. This paper describes a case of significant symptom improvement following 100 Hz accelerated MST treatment in a patient with comorbid TRD and OCD. As a novel treatment option, MST requires further large-scale clinical trials to explore in the future.
