ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

Lung cancer is the most common malignant tumor worldwide, ranking first in both incidence and mortality rates. According to the latest statistics from the International Agency for Research on Cancer (IARC), approximately 2.5 million new cases and around 1.8 million deaths from lung cancer occurred in 2022, placing a tremendous burden on global healthcare systems. The high mortality rate of lung cancer is closely linked to its subtle early symptoms, which often lead to diagnosis at advanced stages. This not only complicates treatment but also results in substantial economic losses. Current treatment options for lung cancer include surgery, radiotherapy, chemotherapy, targeted drug therapy, and immunotherapy. Among these, immunotherapy has emerged as the most groundbreaking advancement in recent years, owing to its unique antitumor mechanisms and impressive clinical benefits. Unlike traditional therapies such as radiotherapy and chemotherapy, immunotherapy activates or enhances the patient’s immune system to recognize and eliminate tumor cells. It offers advantages such as more durable therapeutic effects and relatively fewer toxic side effects. The main approaches to lung cancer immunotherapy include immune checkpoint inhibitors, tumor-specific antigen-targeted therapies, adoptive cell therapies, cancer vaccines, and oncolytic virus therapies. Among these, immune checkpoint inhibitors and tumor-specific antigen-targeted therapies have received approval from the U.S. Food and Drug Administration (FDA) for clinical use in lung cancer, significantly improving outcomes for patients with advanced non-small cell lung cancer. Although other immunotherapy strategies are still in clinical trials, they show great potential in improving treatment precision and efficacy. This article systematically reviews the latest research progress in lung cancer immunotherapy, including the development of novel immune checkpoint molecules, optimization of treatment strategies, identification of predictive biomarkers, and findings from recent clinical trials. It also discusses the current challenges in the field and outlines future directions, such as the development of next-generation immunotherapeutic agents, exploration of more effective combination regimens, and the establishment of precise efficacy prediction systems. The aim is to provide a valuable reference for the continued advancement of lung cancer immunotherapy.

Objective: To analyze the epidemiological characteristics and changing trends of non suicidal self injury (NSSI) behaviors among middle school students in Jiading District of Shanghai, from 2015 to 2023, so as to provide a basis for the development of NSSI prevention and control measures among students. Methods: Using a stratified cluster random sampling method, a total of five times for Shanghai Adolescent Health Risk Behavior Surveys were conducted for every two years in Jiading District of Shanghai from 2015 to 2023. A total of 5 231 middle school students from junior high schools and senior high schools were selected for questionnaire surveys. Intergroup comparisons were performed using the x 2 test or the χ 2 trend test, and the JointPoint 5.0 software was used to analyze the changing trends, with the annual percent change (APC) used for evaluation. A binary Logistic regression model was employed to analyze the related factors of NSSI behavior among middle school students. Results: In 2023, the reported NSSI rate among middle school students in Jiading District was 14.2%. The rate was significantly higher among junior high school students (17.1%) than that among senior high school students (11.1%), and higher among females (19.2%) than that among males (10.0%) ( χ 2=10.04, 23.21, both P <0.01). From 2015 to 2023, the overall reported NSSI rate showed an increasing trend, rising from 8.6% in 2015 to 14.2% in 2023 ( χ 2 trend =22.25), with an APC of 6.64% ( t =3.49), and the APC for girls was 9.79 % ( t =3.20) (all P <0.05). Among students reporting NSSI, the proportion experiencing ≥6 episodes increased from 10.8% in 2015 to 19.2% in 2023 ( χ 2 trend =6.57, P <0.05). Multivariate Logistic regression analysis indicated that girls, junior high school students, those with insomnia, depressive emotion and drinkers had higher risks of NSSI, compared to boys, senior high school students, those without insomnia, non depressive emotion students and non drinkers ( OR =1.71, 1.96, 3.44, 4.76, 1.77, all P < 0.05 ). Conclusions The reported rate of NSSI among middle school students in Jiading District of Shanghai, increased annually from 2015 to 2023, and the proportion of repeated NSSI also showed an upward trend. Early intervention measures targeting middle school students, especially junior high school students and females, should be implemented to prevent and control its occurrence and development.

Aim To explore the mechanism of action of Guizhi Jia Gegen decoction(GGD)in treating pneu-monia-enteritis induced by H1N1 influenza virus infec-tion in a mouse model,using network pharmacology and molecular docking techniques,followed by in vivo verification.Methods A pneumonia-enteritis mouse model was established,and the intervention effects of GGD on the model mice were evaluated using indica-tors such as body weight,rectal temperature,lung in-dex,colon length,H1N1 M gene expression,relative mRNA expression levels of inflammatory cytokines,and pathological sections of the lung and intestine.The targets of the blood-absorbed components of GGD were identified using the Swiss Target Prediction platform,and the disease targets were retrieved from the Gene-Cards platform.The intersecting targets were analyzed through PPI network analysis using the STRING data-base to identify core targets.GO analysis and KEGG pathway enrichment analysis were performed using the Metascape database.RT-qPCR was employed to vali-date the core targets and pathways.Molecular docking was conducted using AutoDock Tools software to verify the interactions between blood-absorbed components and key targets.Results GGD demonstrated signifi-cant therapeutic effects on the pneumonia-enteritis mouse model.The results of network pharmacology in-dicated that the therapeutic effects of GGD were strong-ly associated with targets such as TNF,ALB,PTGS2,MMP9,EGFR,ESR1,SRC,HSP90AA1,PPARG and MMP2.RT-qPCR results indicated that GGD could intervene in pneumonia-enteritis by regulating the targets TNF,ALB,EGFR and the related targets of the NF-κB pathway.Molecular docking results re-vealed that blood-absorbed components such as puerar-in and liquiritin could stably bind to TNF,ALB and EGFR.Conclusion Components such as puerarin and liquiritin in GGD may exert therapeutic effects on pneumonia-enteritis induced by H1N1 influenza virus infection by acting on targets such as TNF,ALB and EGFR.

BACKGROUND:Osteoarthritis is a common degenerative joint disease,and the etiology and development of its pathogenesis are still unclear.Timely diagnosis and treatment of early osteoarthritis are crucial,and there is currently no definite and effective method.Extracellular vesicles come from a wide range of sources,including non-coding RNAs such as small RNAs,circular RNAs,and long chain non-coding RNAs.Extracellular vesicles non-coding RNAs can be directly delivered from primitive cells to neighboring or remote cells,regulating cell activity through intercellular communication and playing an important regulatory role in reshaping the bone and joint microenvironment.OBJECTIVE:To summarize the intervention effects of exosome-derived non-coding RNAs on the joint microenvironment of osteoarthritis and the progress made in clinical application,and to clarify the potential of exosome-derived non-coding RNAs in the diagnosis and treatment of osteoarthritis.METHODS:Search terms "exosomes,non-coding RNA,osteoarthritis,application,signal pathway,synovial fluid,cartilage cells,cartilage matrix,subchondral,mechanism" were used for the search on PubMed database.Finally,66 related articles were included for review analysis.RESULTS AND CONCLUSION:(1) Exosome-derived non-coding RNAs play an important regulatory role in the joint microenvironment during the pathogenesis of osteoarthritis,mainly reflected in:exosome non-coding RNAs regulating the inflammatory response in the joint,degeneration of chondrocytes and cartilage matrix,subchondral bone remodeling,and intercellular communication.(2) The non-coding RNAs in exosomes can serve as biomarkers for osteoarthritis,aiding in the early diagnosis and monitoring of disease progression and prognosis.(3) Exosome non-coding RNAs serve as therapeutic targets for osteoarthritis.Exosomes carry miRNAs to the articular chondrocytes and cartilage matrix to play a regulatory role.(4) Exosomes non-coding RNAs can improve the effect of cartilage tissue engineering by regulating gene expression and promoting intercellular communication to repair or regenerate damaged cartilage.(5) In future research,researchers should continue to explore the intervention mechanism of non-coding RNAs derived from exosomes on osteoarthritis,and apply them to clinical practice in combination with the latest research outcomes in cartilage tissue engineering,which will effectively help solve the pain of osteoarthritis patients.

Objective:To explore the application value of coronary CT angiography(CCTA)combined with serum levels of Krueppel like factor 4(KLF4)and histone deacetylase 4(HDAC4)in assessment of coronary artery steno-sis severity in patients with coronary heart disease(CHD).Methods:A total of 152 CHD patients admitted to Suzhou High tech District People's Hospital between December 2021 and December 2023 were prospectively selected.According to coronary angiography(CAG)quantitative analysis method,patients with CHD were divided into mild stenosis group(n=57),moderate stenosis group(n=49)and severe stenosis group(n=46).Kappa consistency a-nalysis was used to determine the consistency between CCTA detection and CAG in determining the degree of coro-nary stenosis.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of CCTA combined with serum KLF4 and HDAC4 levels for the degree of coronary artery stenosis.Results:Compared to pa-tients in mild stenosis group,those in moderate stenosis group and severe stenosis group had significantly lower levels of KLF4 and HDAC4(P＜0.01 all),and those in severe stenosis group had significantly lower levels of KLF4 and HDAC4 compared to those in moderate stenosis group(P＜0.01 all).According to CCTA diagnosis,there were 53 cases with mild stenosis,53 cases with moderate stenosis and 46 cases with severe stenosis.The consistency rate with CAG diagnosis was 80.92％(123/152),which was relatively high(Kappa=0.713,P＜0.001).The accuracy of CCTA in diagnosing mild,moderate and severe stenosis was 88.16％(134/152),85.53％(130/152)and 88.16％(134/152)respectively.ROC curve analysis indicated the area under the curve(AUC)of CCTA combined with ser-um KLF4 and HDAC4 in the diagnosis of moderate and severe coronary artery stenosis was 0.949(95％CI 0.901～0.978),which was significantly higher than those of CCTA(AUC=0.867,95％CI 0.802～0.916),serum KLF4(AUC=0.895,95％CI 0.825～0.939)and HDAC4(AUC=0.809,95％CI 0.738～0.869)alone(Z=2.806,P＜0.001;Z=2.065,P=0.039;Z=3.552,P＜0.001,respectively).Conclusion:In patients with coronary heart dis-ease,serum levels of KLF4 and HDAC4 are closely related to the degree of coronary artery stenosis.The combina-tion of CCTA,serum KLF4 and HDAC4 levels has good performance in predicting the degree of coronary artery stenosis.
