Objective: To investigate the status and influencing factors of influenza vaccination among the elderly, so as to provide insights into improving the strategies for influenza vaccination among the elderly. Methods: Elderly people aged 60 years and above were recruited from one community each in five sub-districts of Shihezi City, Xinjiang Uygur Autonomous Region using a random sampling method. Demographic information, knowledge about influenza and influenza vaccines, vaccine literacy and influenza vaccination status in the past year were collected through questionnaire surveys. Factors affecting influenza vaccination among the elderly were analyzed using a multivariable logistic regression model. Results: Totally 1 121 valid questionnaires were recovered, with an effective recovery rate of 95.08%. There were 417 males (37.20%) and 704 females (62.80%). The majority were aged 60-<81 years, accounting for 80.37% (901 individuals). The awareness of knowledge about influenza and influenza vaccines was 78.86%. Low vaccine literacy was observed in 786 individuals, representing 70.12%. The influenza vaccination rate was 20.96%. Multivariable logistic regression analysis showed that age (71-<81 years, OR=1.607, 95%CI: 1.041-2.479; ≥81 years, OR=1.719, 95%CI: 1.040-2.842), educational level (middle school/technical secondary school, OR=0.616, 95%CI: 0.416-0.911), medical expense payment (employee medical insurance, OR=6.531, 95%CI: 2.030-21.010; resident medical insurance, OR=3.385, 95%CI: 1.095-10.466; public expense, OR=4.828, 95%CI: 1.700-13.712), vaccination willingness (yes, OR=6.237, 95%CI: 3.277-11.871), influenza vaccination history (yes, OR=14.600, 95%CI: 8.733-24.408) and vaccine literacy (medium and above, OR=2.412, 95%CI: 1.636-3.555) were associated with influenza vaccination among the elderly. Conclusion The influenza vaccination rate among the elderly was relatively low, and was mainly affected by age, educational level, medical expense payment, vaccination willingness, influenza vaccination history and vaccine literacy.

As a complex autoimmune disease， rheumatoid arthritis （RA） involves immune microenvironment dysregulation resulting from excessive activation of pyroptosis， which is a crucial factor in disease progression. Based on the theory of ying-wei in traditional Chinese medicine， "ying decline and wei attack" is considered the fundamental pathogenesis of RA. Pyroptosis serves as a microscopic manifestation of this concept， suggesting a potential correlation between "ying decline and wei attack" and pyroptosis nd immune microenvironment dysregulation in RA. Accordingly， treatment principles based on this theory are proposed： in the early stage of the disease， boosting wei to consolidate the exterior， and regulating ying to dispel pathogens； in the middle and late stages， harmonizing ying to remove stagnation， and nourishing its transformational source.

The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.

BackgroundFamily factors are known to play a critical role in the development， progression and prognosis of adolescent patients with depressive disorder. Psychodrama group therapy has the potential for bringing about positive change in individual growth and relationship repair， but there is currently insufficient research evidence for the effectiveness of psychodrama group therapy in promoting the recovery in depressive disorder in adolescents through improving the family parenting skills of their parents. ObjectiveTo explore the influence of psychodrama group therapy based on family parenting intervention on parents of adolescent patients with depressive disorder， so as to provide references for promoting the recovery for adolescent patients with depressive disorder. MethodsPurposive sampling was used to recruit adolescent patients who met the diagnostic criteria for depressive disorder of the International Classification of Diseases， tenth edition （ICD-10） and hospitalized in the psychiatric outpatient department of the First Affiliated Hospital of Chongqing Medical University from October 2023 to March 2024， and their parents （either mother or father） were taken as the study subjects. Psychodrama group therapy based on family parenting intervention was performed once a week for 6 consecutive weeks. After intervention， semi-structured interviews were conducted with parents who participated in the group， and the interviews were recorded. Content analysis method was employed to perform qualitative analysis on the interview recordings and verbatim transcripts. ResultsAfter receiving psychodrama group intervention based on family parenting， parents of adolescent patients with depressive disorder demonstrated improvement in emotional state， enhanced reflective ability and altered coping style， which were specifically manifested as reducing negative emotions， increasing positive emotions， reflecting on themselves， empathizing with others， adjusting cognition， changing the way of stress regulation， improving communication styles and actively seeking resources. ConclusionApplication of psychodrama group therapy based on family parenting intervention may improve emotional state， reflective ability and coping style of the parents of adolescent patients with depressive disorder. ［Funded by Chongqing Education Commission Humanities and Social Science Research Project （number， 19SKGH018）； Chongqing Social Science Planning Project （number， 2021WT29）］

The lung collaterals form a network that branches from the lung meridian, traversing the lung system and extending across the body′s surface. Lung collateral disease refers to the structural alterations or dysfunction in these collaterals caused by external or internal pathogens. Research into the structural and physiological functions of children′s lung collaterals, as well as the pathogenesis and syndrome differentiation for treating lung collateral diseases in children, holds significant value in guiding the prevention and treatment of pediatric respiratory conditions. Drawing on the theory of collateral disease, the clinical insights of both historical and contemporary physicians, and modern research findings—while considering the unique physiological and pathological characteristics of children′s respiratory systems—this study provides a foundational summary of the morphology and spatial distribution of children′s lung collaterals. The characteristics of these collaterals are highlighted as thin, sparse, short, narrow, brittle, and tender. From this structural understanding, the unique physiological functions of children′s lung collaterals are analyzed. The study further explores the interactions between pathogenic factors and lung collaterals, elucidating the pathogenesis and progression of children′s lung collateral diseases. It proposes treatment principles centered on "seeking treatment in the collaterals and employing the method of unblocking collaterals, "which align with the unique features of pediatric lung collaterals. Common treatment approaches, and relevant prescriptions for managing these diseases are summarized. This paper lays the foundation for a theoretical system encompassing the structure, function, pathogenesis, and syndrome differentiation for treating children′s lung collateral diseases. It offers valuable insights for the clinical diagnosis and management of pediatric respiratory diseases linked to collateral dysfunction and serves as a reference for the systematic development of a broader theoretical framework for children′s collateral diseases.

Hepatocellular carcinoma （HCC） is a common primary malignant tumor. In recent years， the role of ubiquitin-specific proteases （USPs） in HCC has attracted widespread attention. USPs are a class of key deubiquitinating enzymes that affect a variety of biological processes by regulating the ubiquitination status of proteins. Studies have shown that USPs participate in the regulation of cell proliferation， apoptosis， migration， and invasion by deubiquitinating various tumor-related proteins. In addition， the abnormal expression of USPs is closely associated with the prognosis of HCC patients and may thus be used as potential biomarkers and therapeutic targets. This article reviews the research advances in USPs in HCC and explores their key roles in the development， progression， and metastasis of HCC. A deep understanding of the mechanism of action of USPs in HCC not only helps to reveal the pathogenesis of HCC， but also provides a scientific basis for developing new diagnostic tools and treatment strategies. Future research should further explore the regulatory effect of USPs in HCC， in order to provide more effective means for the clinical treatment of HCC.

BackgroundObsessive-compulsive disorder （OCD） is a common neuropsychiatric illness and is listed as one of the top ten disabling conditions causing loss of income and reduced quality of life. Psychological distress is an important cause of anhedonia in OCD patients， and is closely related to psychosomatic symptoms. Therefore， exploring the role of anhedonia in the relationship between psychological distress and psychosomatic symptoms is of great significance for optimizing clinical psychological treatment protocols for OCD patients. ObjectiveTo explore the role of anhedonia in the relationship between psychological distress and psychosomatic symptoms in OCD patients， with the aim of providing references for managing psychosomatic symptoms in patients. MethodsA total of 90 patients who met the diagnostic criteria for OCD according to the International Classification of Diseases， tenth edition （ICD-10）， and who visited the Mental Health Center outpatient clinic of General Hospital of Ningxia Medical University from September 2023 to November 2024 were selected as the study objects. The instruments and techniques used for the evaluation were： Dimensional Anhedonia Rating Scale （DARS）， 10-item Kessler Psychological Distress Scale （K10） and Psychosomatic Symptom Scale （PSSS）. Model 4 of the Process for SPSS 26.0 was used to test the mediating role of anhedonia in the relationship between psychological distress and psychosomatic symptoms， with Bootstrapping used to assess the significance of mediating effect. ResultsA total of 84 patients （93.33%） completed the valid questionnaire. K10 score was positively correlated with PSSS total score， psychological symptom score and physical symptom score （r=0.559， 0.460， 0.551， P<0.01）. K10 score was negatively correlated with DARS total score （r=-0.527， P<0.01）. The total score of DARS was negatively correlated with PSSS total score （r=-0.497， P<0.01）. Anhedonia mediated the relationship between psychological distress and psychosomatic symptoms， with an indirect effect value was 0.148 （95% CI： 0.042~0.278）， accounting for 26.48% of the total effect. ConclusionPsychological distress can affect the psychosomatic symptoms in OCD patients both directly and indirectly via anhedonia.

Liver cancer has high prevalence and mortality rates around the world， and its development and progression are closely associated with the interaction between the tumor microenvironment and tumor-associated macrophages （TAMs）. TAMs play a significant role in immune suppression， immune escape， cell proliferation， invasion， metastasis， and drug resistance in liver cancer. Traditional Chinese medicine （TCM）， with its unique therapeutic concepts and methods， has shown great potential in regulating TAMs and improving the prognosis of liver cancer. This article reviews the role and molecular mechanisms of TCM in regulating TAMs for the treatment of liver cancer， discusses the key role of TAMs in the progression of liver cancer， and analyzes the impact of Chinese medicinal components on the recruitment， polarization， and activity of TAMs and the expression of related factors based on TCM theory. Studies have shown that TCM can regulate the polarization state of TAMs， promote the formation of M1-type antitumor macrophages， and inhibit the activity of M2-type tumor macrophages， thereby playing a role in inhibiting the proliferation of liver cancer cells， promoting apoptosis， inhibiting angiogenesis， and enhancing immune response. In addition， this article also summarizes the molecular targets and mechanisms of action of TCM monomers， compound prescriptions， and novel preparations in the treatment of liver cancer， such as inhibiting the secretion of cytokines by TAMs， regulating signaling pathways， and affecting metabolic pathways， in order to provide a scientific basis for the application of TCM in liver cancer treatment and offer new ideas for immunotherapy for liver cancer.

OBJECTIVE To investigate the improvement effects of Runchang granules on the constipation in mice and its potential mechanism. METHODS The mice were randomly divided into normal control group， model group， Runchang granules low-dose and high-dose groups （5， 10 g/kg）， mosapride group （0.003 g/kg， positive control）， with 6 mice in each group. The latter 4 groups were given loperamide intragastrically （0.004 g/kg）， twice a day， for 3 consecutive days. Normal control group and model group were given purified water intragastrically， and administration groups were given relevant medicine intragastrically for 7 consecutive days. After the last medication， fecal moisture content and intestinal motility of mice were determined， while the structures of colon and ileum， and the secretion of colonic mucus were observed. Protein expressions of tyrosine kinase receptor （c-kit）， mucin 2 （MUC2） and stem cell factor （SCF） were determined in colon； meanwhile， the mRNA expression levels of inflammatory factors [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， inducible nitric oxide synthase （iNOS）] as well as factors related to promoting intestinal motility [neuronal nitric oxide synthase （nNOS）， smooth muscle myosin light chain kinase （smMLCK）， 5-hydroxytryptamine 4 receptor （5-HT4R）， MUC2， SCF， c-kit] were determined. RESULTS Compared with model group， the fecal water content， intestinal propulsion rate， protein expression of c-kit in colon， relative expressions of MUC2 and SCF protein， and mRNA expressions of factors related to promoting intestinal motility （except for nNOS and SCF in Runchang granules low-dose group） were all increased significantly in Runchang granules low-dose and high-dose groups， and mosapride group （P＜0.05 or P＜0.01）. mRNA expression levels of inflammatory factors were decreased significantly（P＜0.05 or P＜0.01）. Both colon and ileum injuries improved， and the secretion of colon mucus was increased significantly in Runchang granules high-dose group （P＜0.01）. CONCLUSIONS Runchang granules have laxative effect and can improve constipation in mice， and its mechanism may be related to the promotion of the secretion of colon mucus and MUC2 expression， and the activation of SCF/c-kit signaling pathway.

BACKGROUND:Current osteoarthritis modeling methods include anterior cruciate ligament transection(ACLT)and ACLT combined with medial meniscal anterior horn resection.ACLT requires excessive postoperative exercise,which is time and labor-intensive.Complete removal of anterior horn of the medial meniscus can cause collateral damage and increase variability in modeling outcomes,requiring higher surgical skills from the surgeon. OBJECTIVE:To modify and simplify the traditional method to create animal osteoarthritis model and compare osteoarthritis symptoms of different modeling methods under a low-load exercise environment. METHODS:Forty-eight Sprague-Dawley rats were randomly assigned in four groups(n=12 per group):sham operation(complete exposure of the knee cavity of the left hind limb followed by suturing the joint cavity and skin),ACLT,ACLT+anterior horn resection(removal of the anterior horn of the medial meniscus)and ACLT+anterior horn tear(anterior horn tear of the medial meniscus).At 4 weeks after modeling,the rats were euthanized and their knee specimens were collected for gross observation,X-ray and CT scans,pathological observation,and PCR detection. RESULTS AND CONCLUSION:Gross observation:Mild meniscal wear was observed in the ACLT group.In the ACLT+anterior horn tear group,severe wear of the lateral condyle articular surface,mild wear of the medial condyle articular surface,severe meniscal wear,and full wear of the medial meniscus were observed.The ACLT+resection group showed severe wear of the lateral condyle articular surface,mild wear of the medial condyle articular surface,absence of the anterior horn of the medial meniscus,and meniscus wear area＞50%.Imaging examinations showed no significant difference among the four groups.However,the anterior tibial translocation sign was observed in the three operation groups and the anterior horn of the medial meniscus was missing in the ACLT+anterior horn resection group.Histopathological section observation:Hematoxylin-eosin,toluidine blue,and Sirius red staining showed smooth joint surfaces in the sham operation group and ACLT group;cartilage damage and matrix degradation were evident in the ACLT+anterior horn tear and ACLT+anterior horn transection groups,with less cartilage damage and matrix degradation in the ACLT+anterior horn tear group.PCR results showed higher mRNA expressions of interleukin 1β,interleukin 6,interleukin 8,tumor necrosis factor α,matrix metalloproteinase 1 and matrix metalloproteinase 3 and lower mRNA expressions of aggrecan in the ACLT+anterior horn tear group and ACLT+anterior horn resection group than in the sham operation group and ACLT group(P＜0.05).The mRNA expressions of interleukin 6,matrix metalloproteinase 1,and matrix metalloproteinase 3 were higher in the ACLT + anterior horn resection group than in the ACLT +anterior horn tear group(P＜0.05).To conclude,ACLT alone is less likely to induce osteoarthritis with obvious cartilage wear.ACLT combined with anterior horn resection or tear of the medial meniscus can induce obvious symptoms of osteoarthritis and achieve similar modeling effects.
