With the main pathological features of glomerulosclerosis and interstitial fibrosis， renal fibrosis is a key pathological process causing chronic kidney disease to progress to end-stage disease. As a cellular autophagic process， mitochondrial autophagy plays a crucial role in maintaining mitochondrial mass and functional stability. Mitochondrial dysfunction is considered to be one of the key factors driving the progression of fibrosis. Phosphatase and tension protein homologue （PTEN） induce various signalling pathways such as putative kinase 1/parkin， Nip3-like protein X/Bcl-2 interacting protein 3， and FUN14 structural domain-containing protein 1 to activate mitochondrial autophagy to participate in the regulation of fibrogenic factors， amelioration of oxidative stress， and inhibition of inflammatory response and apoptosis， which in turn effectively slows down the progression of renal fibrosis. Studies have shown that traditional Chinese medicine monomers and compound preparations， including phenolics， terpenoids， ketones， and alkaloids， can regulate mitochondrial autophagy-related signalling pathways and achieve significant clinical efficacy in intervening in the progression of renal fibrosis for the treatment of chronic kidney disease. This paper summarized the mechanism of mitochondrial autophagy and the research progress of traditional Chinese medicine intervention in renal fibrosis to provide new ideas for the study of the mechanism of traditional Chinese medicine in treating renal fibrosis.

OBJECTIVE To analyze the impact of intergenerational substitution effect of the drugs with the same indication on fund expenditures for national medical insurance for this indication in China， taking national medical insurance negotiated drugs for non-small cell lung cancer （hereinafter referred to as “NSCLC national negotiation drugs”） as an example. METHODS The sales amounts of 15 types of NSCLC national negotiated drugs in secondary and tertiary public hospitals across seven sample provinces from 2017 to 2023 were collected from the Pharmaceutical Drug Database of the China National Pharmaceutical Industry Information Center. A sliding t-test and Mann-Kendall trend test were used to evaluate the trends in sales amounts and DDDs. Taking epidermal growth factor receptor（EGFR）-tyrosine kinase inhibitors （TKIs） and anaplastic lymphoma kinase （ALK）-TKIs as examples， the generational substitution characteristics of these drugs were analyzed. RESULTS The change points of sales amounts and DDDs differed slightly across provinces； the change points of sales amount were mostly concentrated between the first quarter of 2019 and the second quarter of 2020， while those for DDDs were primarily concentrated in the first to second quarters of 2021. In five provinces， i.e. Beijing， Heilongjiang， Jiangsu， Sichuan and Shaanxi， sales amounts showed no significant upward trend after the breakpoints （P＞0.05）， whereas in Guangdong and Hubei， both sales amounts and DDDs continued to rise significantly following the breakpoints （P＜0.05）. Since 2020， the growth in sales amounts of EGFR-TKIs had slowed. After 2021， the sales amounts and DDDs of first- and second-generation EGFR-TKIs declined， while third-generation EGFR-TKIs showed clear substitution effects. The sales amounts of ALK-TKIs continuedto grow. However， the sales amounts and DDDs of first-generation ALK-TKIs had declined year by year， with second-generation ALK-TKIs demonstrating a significant substitution effect on first-generation ones， while third-generation ALK-TKIs had not yet shown a clear substitution trend. CONCLUSIONS With the annual access to and renewal of drugs in national medical insurance negotiations， the overall expenditure trend for NSCLC negotiated drugs comes to a plateau. The intergenerational substitution relationships of drugs with the same indication achieve a relative balance in fund expenditures for negotiated drugs with the same indication. It is recommended that pharmaceutical companies carefully consider their research pipelines， and that medical insurance authorities， during the renewal management process， pay attention to the impact of drug substitution effects on the overall actual expenditure of medical insurance funds for that specific target or the same indication， and scientifically evaluate the extent of price reductions during contract renewals.

BACKGROUND: Currently, lung cancer is one of the malignant tumors with a high morbidity and mortality all over the world. However, the exact mechanisms underlying lung cancer progression remain unclear. The tumor necrosis factor receptor associated factor (TRAF) family members are cytoplasmic adaptor proteins, which function as both adaptor proteins and ubiquitin ligases to regulate diverse receptor signalings, leading to the activation of nuclear factor kappa-B (NF-κB), mitogen-activated protein kinase (MAPK) and interferon regulatory factor (IRF) signaling. The aim of this study was to investigate the expression of TRAFs in different tissues and cancer types, as well as its mRNA expression, protein expression, prognostic significance and functional enrichment analysis in non-small cell lung cancer (NSCLC), in order to provide new strategies for the diagnosis and treatment of NSCLC. METHODS: RNA sequencing data from the The Genotype-Tissue Expression database was used to analyze the expression patterns of TRAF family members in different human tissues. RNA sequencing data from the Cancer Cell Line Encyclopedia database was used to analyze the expression patterns of TRAF family members in different types of cancer cell lines. RNA sequencing data from the The Cancer Genome Atlas (TCGA) database was used to analyze the mRNA levels of TRAF family members across different types of human cancers. Immunohistochemistry (IHC) analyses from HPA database were used to analyze the TRAF protein levels in NSCLC [lung adenocarcinoma (LUAD) and lung squamous carcinoma (LUSC)]. Overall survival analysis was performed by Log-rank test using original data from Kaplan-Meier Plotter database to evaluate the correlation between TRAF expressions and prognosis. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed on the TRAF family-related genes using RNA sequencing data from the TCGA database for NSCLC. The correlation between the expression levels of TRAF family members and the tumor immune microenvironment was analyzed using the ESTIMATE algorithm based on RNA sequencing data from the TCGA database. RESULTS: The TRAF family members exhibited significant tissue-specific expression heterogeneity. TRAF2, TRAF3, TRAF6 and TRAF7 were widely expressed in most tissues, while the expressions of TRAF1, TRAF4 and TRAF5 were restricted to specific tissues. The expressions of TRAF family members were highly specific among different types of cancer cell lines. In mRNA database of LUAD and LUSC, the expressions of TRAF2, TRAF4, TRAF5 and TRAF7 were significantly upregulated; while TRAF6 did the opposite; moveover, TRAF1 and TRAF3 only displayed a significant upregulation in LUAD and LUSC, respectively. Except for TRAF3, TRAF4 and TRAF7, other TRAF proteins displayed an obviously deeper IHC staining in LUAD and LUSC tissues compared with normal tissues. Additionally, patients with higher expression levels of TRAF2, TRAF4 and TRAF7 had shorter overall survival; while patients with higher expression levels of TRAF3, TRAF5 and TRAF6 had significantly longer overall survival; however, no significant difference had been observed between TRAF1 expression and the overall survival. TRAF family members differentially regulated multiple pathways, including NF-κB, immune response, cell adhesion and RNA splicing. The expression levels of TRAF family members were closely associated with immune cell infiltration and stromal cell content in the tumor immune microenvironment, with varying positive and negative correlations among different members. CONCLUSIONS TRAF family members exhibit highly specific expression differences across different tissues and cancer types. Most TRAF proteins exhibit upregulation at both mRNA and protein levels in NSCLC, whereas, only upregulated expressions of TRAF2, TRAF4 and TRAF7 predict worse prognosis. The TRAF family members regulate processes such as inflammation, immunity, adhesion and splicing, and influence the tumor immune microenvironment.

Objective:To retrospectively analyze the results of auditory examination,vestibular function examination and laboratory examination of 63 patients diagnosed as vestibular neuritis.Methods:A total of 63 patients diagnosed with vestibular neuritis hospitalized in the Department of Otolaryngology, Head and Neck Surgery of the Third Affiliated Hospital of Sun Yat-sen University, from October 2012 to December 2022 were recruited. All patients met the diagnostic criteria for the 2022 Bárány association vestibular neuritis. Clinical data and the results of pure tone audiometry, electrocochleogram, video electronystagmogram, caloric test, cervical vestibuloevoked myogenic potential（cVEMP）, ocular vestibuloevoked myogenic potential（oVEMP）, video head impulse test（vHIT） was collected.A total of 63 age-and sex-matched healthy subjects in the physical examination center were randomly selected as the control group. The differences of blood indexs and lipid metabolism indexes between the two groups were compared. Results:In patients with vestibular neuritis, 50 out of 63 patients presented normal threshold in pure tone audiometry, 8 out of 63 patients had bilateral high-frequency sensorineural hearing loss and 5 out of 63 patients had unilateral mild high-frequency sensorineural hearing loss, 56 out of 63 cases completed the electrocochleogram, of which 3 cases had a binaural-SP/AP amplitude ratio≥0.4, 5 cases had monaural amplitude ratio ≥0.4. Fifty-five out of 63 patients completed the caloric test with CP values greater than 30% in all. The ratio of patients completed cVEMP, oVEMP and vHIT were 46 cases, 22 cases and 30 cases, respectively. 17 out of 63 cases completed all the four vestibular function tests. According to these tests, 49 patients could determine the extent of injury，including 27 cases with unilateral superior vestibular nerve injury, 21 cases with unilateral superior and inferior vestibular nerve injury and 1 case with unilateral inferior vestibular nerve injury. There were significant differences in neutrophil value（P<0.001）, lymphocyte value（P<0.005）, neutrophil/lymphocyte ratio（P<0.001） and apolipoprotein A1（P<0.001） between patient group and control group. Inflammatory markers were risk factors for patients with vestibular neuritis. The OR values of neutrophil value and blood neutrophil/lymphocyte ratio were 1.81（1.38-2.37, P<0.001） and 2.11（1.41-3.16, P<0.001）, respectively. Apolipoprotein A1 was a protective factor for patients with vestibular neuritis, and the OR value was 0.004（0.001-0.042, P<0.001）. Conclusion:Electrocochleogram could be used in vestibular neuritis patients with normal pure tone threshold to test whether there is hidden hearing loss in these patients. Neutrophil value, lymphocyte value, neutrophil/lymphocyte ratio and apolipoprotein A1 were correlated with vestibular neuritis. The Neutrophil value and neutrophil/lymphocyte ratio were risk factors for morbidity.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective To systematically review whether mirror therapy(MT)intervention can effectively improve upper extremity motor function and activities of daily living(ADL)in stroke patients;whether its improvement is affected by pa-tients'age and disease course;and whether MT's influencing factors,such as intervention period,time,and fre-quency,have a dosage effect on upper extremity motor function and ADL. Methods Seven databases were searched,including Embase,Web of Science,PubMed,Cochrane Library,Wanfang data,VIP and CNKI from establishment to April,2023,and randomized controlled trials of MT for upper extremity motor function and ADL in stroke patients were screened.Quality assessment was performed using Physiothera-py Evidence Database(PEDro).Meta-analysis was performed using RevMan 5.4.1,and network meta-analysis was performed using R software,reticulated meta-analysis tables and cumulative probability tables were drawn for ranked comparisons,and funnel plots were drawn to test for publication bias of the outcome indicators using Stata 17.0 software.GRADE was used to evaluate the quality of evidence for the outcome indicators. Results A total of 13 papers(532 patients)were included.The PEDro score ranged from 6 to 8.Most of the literature did not report the blinding completely or did not implement allocation concealment,which might have some limita-tions.MT could improve the scores of Fugl-Meyer Assessment-Upper Extremities(n = 466,MD = 6.05,95%CI 3.44～8.66,P<0.001),Barthel index(n = 230,MD = 9.95,95%CI 6.23～13.68,P<0.001)and Functional Inde-pendence Measure(n = 147,MD = 4.17,95%CI 2.61～5.72,P<0.001)in stroke patients.Network meta-analysis showed that MT was more effective in upper limb motor function intervention for stroke patients aged 40 to 59 years with a disease course less than three months;and an intervention period less than four weeks,single inter-vention time less than 30 minutes,intervention duration daily more than 30 minutes and intervention twice daily might optimize the effects on upper limb motor function. Conclusion MT is effective on upper limb motor function and ADL in stroke patients,and the effect on upper limb mo-tor function is affected by the age and disease course of the patients,as well as the period,time and frequency of intervention.

Objective To summarize the liver biopsy and clinical features of patients with liver injury of unknown origin,and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin.Methods A retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital,Xiamen University,from January 2018 to February 2023.According to the proportion of the patients with different final diagnoses,the patients were divided into autoimmune liver disease(AILD)group,metabolic associated fatty liver disease(MAFLD)group,drug-induced liver injury(DILI)group,alcoholic liver disease(ALD)group,and unknown group.An analysis of variance was used for comparison of normally distributed continuous data between multiple groups,and the Bonferroni analysis or the Dunnett'T3 test was used for further comparison between two groups;the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups;the Fisher's exact test was used for comparison of categorical data between multiple groups.Results All 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission,among whom 90 patients(95.7%)had a confirmed diagnosis based on liver biopsy and clinical features.There were 43 patients(45.7%)with AILD,21(22.3%)with MAFLD,15(16.0%)with DILI,6(6.4%)with ALD,1(1.1%)with AILD and MAFLD,1(1.1%)with hemochromatosis,1(1.1%)with Budd-Chiari syndrome,1(1.1%)with congenital hepatic fibrosis,and 1(1.1%)with idiopathic portal hypertension,while 4 patients(4.3%)still had an unknown etiology after liver biopsy.There were significant differences between the patients with top five diagnoses in age(F=4.457,P<0.05),body mass index(BMI)(F=3.245,P<0.05),aspartate aminotransferase(AST)(H=11.128,P<0.05),gamma-glutamyl transpeptidase(GGT)(H=24.789,P<0.05),alkaline phosphatase(ALP)(H=26.013,P<0.05),IgG(H=19.099,P<0.05),IgM(H=21.263,P<0.05),AMA-M2 positive rate(P<0.05),and ANA positive rate(P<0.05).Compared with the MAFLD group,the AILD group had significantly higher age,AST,GGT,and ALP and a significantly lower BMI;compared with the MAFLD group and the DILI group,the AILD group had significant increases in IgG and IgM;the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups.Conclusion AILD,MAFLD,and DILI are the most common causes in patients with liver injury of unknown origin.Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin,but it is still needed to make a comprehensive analysis based on clinical history,different types of liver injury,laboratory markers,and imaging data.

ObjectiveTo investigate the relationship of physical activity (PA) and cognitive function to sleep quality in older adults with cognitive impairment based on resting electroencephalogram (EEG), and to explore the mediating role of specific EEG markers in the relationship between PA and sleep quality. MethodsFrom March to May, 2024, 137 older adults were recruited from Chenfu Jiayuan and Qiangwei Jiuli in Songjiang district, and Luyan communities in Jinshan district, Shanghai. The assessments included Montreal Cognitive Assessment (MoCA), International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Pittsburgh Sleep Quality Index (PSQI), along with a five-minute EEG recording. ResultsThere was significant difference in sleep quality among older adults with different levels of cognitive impairment (t = -7.400, P < 0.001). The PSQI total score was negatively correlated with MoCA scores (r = -0.412, P < 0.001) and total physical activity level (PAL) (r = -0.363, P < 0.001). The θ power in the frontal areas (F3, F4) was significantly correlated with both PSQI scores and PAL (P < 0.01). The θ power in F3 + F4 exhibited a significant partial (effect size = -0.0004, 95%CI -0.0007 to -0.0002) mediating effect between PA and sleep quality in older adults with cognitive impairment. ConclusionOlder adults with more severe cognitive impairment tend to have poorer sleep quality, whereas higher PAL is associated with better sleep quality. PA can indirectly influence sleep quality in older adults with cognitive impairment by affecting θ power (F3 + F4).

Arsenic, a naturally occurring metal-like chemical element, is one of the 10 chemicals of major public concerns listed by the World Health Organization as harmful to the environment and human health. It can enter the human body through breathing, intaking food, drinking water, skin exposure, and other ways, and long-term exposure to arsenic can cause cancer of multiple organs and impaired function of multiple systems. Epigenetic mechanisms play an important role in arsenic-induced health effects, and research suggested that the carcinogenicity of arsenic may be associated with epigenetic changes. Previous studies focused on the effects of arsenic on DNA methylation modification. In recent years, research showed that 5-hydroxymethylcytosine (5-hmC), an intermediate of active demethylation of DNA, can act as a sensitive epigenetic mark and play a crucial role as a "bridge" between arsenic exposure and health effects. Based on the latest research progress on the role of DNA hydroxymethylation in the health effects associated with arsenic exposure, this article briefly described the relationship between the health effects of arsenic exposure and DNA hydroxymethylation, summarized the possible mechanisms of DNA hydroxymethylation in the health effects associated with arsenic exposure, and provided a scientific basis for preventing and treating the health effects associated with arsenic exposure.
