Objective:To investigate the current status of subjective well-being among stroke patients, and to explore the pathways and effects of influencing factors using structural equation model, so as to provide reference for improving subjective well-being among stroke patients.Methods:From July to November 2024, the stroke patients admitted to the First Affiliated Hospital of Bengbu Medical University, the Second Affiliated Hospital of Bengbu Medical University, Hefei First People′s Hospital were selected by convenience sampling method. A cross-sectional survey was conducted using a general demographic questionnaire, General Well-Being Scale, Cognitive Reserve Index questionnaire, Social Support Rating Scale, Stroke Symptom Cluster Scale, and FRAIL Scale, and AMOS 26.0 was used to analyse the pathways and effects of influencing factors of subjective well-being.Results:A total of 435 questionnaires were collected, 410 were valid.Among 410 cases, 266 case were males, 144 were females, with an age of (65.96 ± 12.15) years. The subjective well-being scores of stroke patients were (72.58 ± 11.66) points. Cognitive reserve and social support were positively correlated with subjective well-being ( r = 0.517, 0.554, both P<0.01), while symptom burden and frailty were negatively correlated with subjective well-being ( r = -0.687, -0.670, both P<0.01). Path analysis showed that symptom burden, frailty, cognitive reserve, and social support had a direct impact on subjective well-being (path coefficients were -0.500, -0.266, 0.148, and 0.144, respectively, all P<0.05), while cognitive reserve, social support, and symptom burden had an indirect impact on subjective well-being (path coefficients were 0.287, 0.249, and 0.108, respectively, all P<0.05). Conclusions:The subjective well-being of stroke patients is influenced by multiple factors, with symptom burden being an important factor affecting subjective well-being. Intervention strategies such as improving cognitive reserve, strengthening social support systems, and preventing frailty can improve the subjective well-being of patients.

OBJECTIVES: Non-suicidal self-injury (NSSI) is a common mental health and behavioral issue among adolescents. This study aims to investigate the developmental trajectory of adolescent NSSI and gender differences, providing a foundation for better prevention and intervention. METHODS: A longitudinal study was conducted using the Adolescent Self-Injury Scale (ASIS) in a cohort of 1 042 junior high school students from 3 middle schools in Zhangjiajie, Hunan Province. Participants were surveyed 3 times at 6-month intervals. A latent growth curve model was constructed using Mplus8.0 to examine the development trajectory of NSSI, and multi-group comparisons were used to assess gender differences. RESULTS: Detection rates of NSSI at the 3 time points were 43.95%, 44.43%, and 38.36%, respectively. Mean of the intercept factor of the LGCM for adolescent NSSI behavior was 9.540 (P<0.001), and the mean slope was -2.297 (P<0.001). Both the variances of the intercept (σ²=169.431, P<0.001) and slope (σ²=141.981, P<0.001) were significant, with a significant negative correlation between intercept and slope (r=-0.559, P<0.001). There were no statistically significant gender differences in initial level or rate of change of NSSI behaviors (P>0.05). CONCLUSIONS NSSI is relatively prevalent among adolescents, with female adolescents experiencing more severe NSSI. Individual differences exist in both the initial level and rate of change of NSSI, and overall, adolescent NSSI shows a decreasing trend over time. No significant gender differences were found in the trajectory of change.

In patients with acute ischemic stroke, there is a wide variation in the composition of blood clots that block the blood vessels. Some imaging features are associated with the components of the clot, such as thrombus permeability, which is related to higher red blood cell density and lower fibrinogen density. The different components and mechanical properties of the clot may have an impact on treatment effectiveness and risk. Therefore, this article aims to summarize the correlation between thrombus permeability and biological, imaging characteristics, and explore the clinical significance of thrombus permeability in the treatment of patients with acute ischemic stroke, providing reference and assistance for neurologists.

ObjectiveTo investigate the effect and possible mechanism of Sishenwan in ameliorating visceral sensitivity in the rat model of diarrhea-predominant irritable bowel syndrome （IBS-D） due to spleen-kidney Yang deficiency. MethodForty male SPF-grade rats were randomly assigned into five groups： blank control， model， low- （3.51 g·kg^-1） and high-dose （7.02 g·kg^-1） Sishenwan， and Peifikang （0.54 g·kg^-1） groups. Except the blank control group， the other groups underwent maternal separation stress and Sennae Folium decoction gavage for the modeling of IBS-D due to spleen-kidney Yang deficiency. After corresponding drug interventions， the general conditions of the rats were observed， and the number of defecation pellets within 6 h and the minimum threshold of abdominal withdrawal reflex （AWR） were measured. Enzyme-linked immunosorbent assay （ELISA） was used to measure the serum levels of tumor necrosis factor （TNF）-α， gastrin （GAS）， corticosterone （CORT）， and adrenocorticotropic hormone （ACTH）. Hematoxylin-eosin （HE） staining was employed to observe pathological changes in the colon tissue. Toluidine blue staining was used to assess mast cell degranulation in the colon tissue. Western blot was performed to determine the protein levels of p38 mitogen-activated protein kinase （MAPK）， c-Jun N-terminal kinase （JNK）， transient receptor potential vanilloid 1 （TRPV1）， and protease-activated receptor 2 （PAR2） in the colon tissue. Immunohistochemistry was employed to measure the protein level of TRPV1 in the colon tissue， and immunofluorescence was used to detect the positive expression of substance P （SP） and calcitonin gene-related peptide （CGRP） in the colon tissue. ResultCompared with the blank control group， the model group showed increased number of defecation pellets within 6 h （P<0.01）， decreased minimum threshold of AWR （P<0.01）， elevated serum TNF-α level （P<0.01）， lowered levels of GAS， CORT， and ACTH （P<0.05， P<0.01）， increased mast cell degranulation rate （P<0.01）， increased positive expression of TRPV1， SP， and CGRP （P<0.05， P<0.01）， and upregulated protein levels of p38 MAPK， JNK， TRPV1， and PAR2 （P<0.01）. Compared with the model group， the high-dose Sishenwan group showed increased minimum threshold of AWR （P<0.01）， reduced defecation frequency in both the high-dose Sishenwan and Peifikang groups （P<0.05， P<0.01）， lowered TNF-α level （P<0.05， P<0.01）， elevated levels of GAS， CORT， and ACTH （P<0.05， P<0.01）， decreased mast cell degranulation rate （P<0.01）， reduced positive expression of TRPV1， SP， and CGRP （P<0.05， P<0.01）， and downregulated protein levels of p38 MAPK， JNK， TRPV1， and PAR2 （P<0.05， P<0.01）. ConclusionSishenwan can ameliorate visceral sensitivity in the rat model of diarrhea-predominant irritable bowel syndrome due to spleen-kidney Yang deficiency by regulating the p38 MAPK/JNK/TRPV1 signaling pathway.

Objective To analyze the risks and related influencing factors of early screening for lung cancer,and to study prognostic factors based on survival conditions,in order to ultimately provide baseline data for the prevention and treatment of lung cancer.Methods A cluster sampling method was used to select 40 to 75 year old registered residence residents in 10 districts and 6 counties of Zhengzhou City in 2020 as screening objects.Through voluntary participation and filling in evaluation questionnaires,high-risk groups of lung cancer were evalu-ated,and then three screening tests(tumor markers,low-dose spiral CT and lung function)were performed on high-risk groups.Finally,we will adopt an active and passive follow-up approach to collect information on diag-nosed lung cancer patients.Statistically describe the screening data and describe the epidemiological results of different characteristic populations;Using multivariate logistic regression method for statistical analysis,compare the differences in various results of different factors.Results 50128 cases of early screening for lung cancer in Zhengzhou City were evaluated in 2020,with a completion rate of 100.26%.The average age of the survey was(59.86±17.67)years old,and the gender ratio was 0.81∶1.The high-risk detection rate is 30.15%.Multivariate logistic regression analysis showed that males(smoking)(OR=5.43,95%CI:5.20～5.67),individuals with a history of tobacco exposure(OR=3.82,95%CI:3.67～3.98),first-degree relatives who had previously suffered from lung cancer(OR=12.06,95%CI:11.02～13.20),and other populations were more susceptible to lung cancer(all P<0.05).Conclusion Male(smoking),exposure to secondhand smoke,cancer in first-degree relatives,previous diagnosis of other tumors,symptoms of lung infection,"chest tightness,shortness of breath,and difficulty breathing in daily life",and"significant psychological trauma in the past 3 years"are independent risk factors for lung cancer,which should be given special attention and effective intervention measures should be taken.
