OBJECTIVE To investigate the ameliorating effect and mechanism of the effective substance groups from Artemisia ordosica（Abbreviated as HSH） on rheumatoid arthritis （RA） based on cluster of differentiation 4/lymphocyte cell-specific protein- tyrosine kinase/zeta-chain-associated protein kinase of 70 kDa/interleukin-17（CD4/LCK/ZAP70/IL-17） signaling pathway. METHODS The rats were divided into normal group， model group， HSH low-dose， medium-dose and high-dose groups （2.7， 10.8， 21.6 mg/kg） and positive control group （Tripterygium glycosides tablet， 6.3 mg/kg）， with 10 rats in each group. Except for normal group， RA rat model was induced by complete Freund’s adjuvant in other groups. After modeling， each group was given relevant medicine or normal saline intragastrically， once a day， for 28 consecutive days. The changes in ankle joint swelling and arthritis index in rats were determined； the pathological changes of ankle joint tissue were observed； the levels of inflammatory factors [IL-1β， IL-21， IL-17A， IL-2， interferon-γ （IFN-γ） and IL-6] in serum and joint fluid of rats were determined； the levels of Th1， Th17 and Treg cells in the whole blood and spleen of rats were detected； protein and mRNA expressions of LCK， proto-oncogene tyrosine-protein kinase Fyn （Fyn）， ZAP70， CD45， RAR-related orphan receptor γt （RORγt）， and forkhead box protein 3 （Foxp3） in ankle synovial tissue were determined. RESULTS Compared with normal group， the changes in ankle joint swelling， arthritis index， the levels of IL-1β， IL-21， IL-17A， IL-2， IFN-γ and IL-6 in serum and joint fluid， the levels of Th1， Th17 cells and Th17/Treg value in whole blood and spleen， and the protein and mRNA expression levels of LCK， Fyn， ZAP70， CD45， and RORγt in ankle joint synovium were all significantly increased/elevated （P＜0.05）. The level of Treg cells in the spleen， as well as the protein and mRNA expression levels of Foxp3 in the ankle joint synovium were significantly decreased （P＜0.05）. Compared with model group， most of the above-mentioned indicators were significantly reversed in the positive control group and all dose groups of HSH （P＜0.05）. The degree of pathological changes in ankle joint tissues was markedly improved， and inflammation was alleviated. CONCLUSIONS HSH can regulate the cascade reactions in the CD4/LCK/ZAP70/IL-17 pathway within the T-cell receptor signaling pathway， thereby modulating the Th17/Treg balance. This leads to the suppression of inflammatory responses and the alleviation of synovial tissue damage in rats with RA.

Objective: To analyze the implementation status and challenges of sex education in special education schools, so as to provide a scientific basis for formulating effective promotion strategies. Methods: From November 2023 to January 2024, a census survey was conducted among 120 in service teachers from 7 special education schools in Luzhou. The questionnaire covered the current status of sex education in schools, teachers attitudes and knowledge toward sex education, and their coping methods for students inappropriate sexual behaviors. Results: About 77.5% of teachers reported having provided sex education to students, but 93.2% indicated a lack of specialized sex education textbooks for special children, 90.4% reported no full time teachers for sex education, and the methods of sex education were relatively limited (50.0% mainly based on lecture method). Nearly 95.8% of teachers held a positive attitude toward sex education, with 98.3% supporting its implementation. Only 26.7% of teachers demonstrated a good grasp of sex education knowledge, with the best understood topic being "recognition and protection of private parts" (21.6%). When dealing with students inappropriate sexual behaviors, the active response rate of teachers was 23.9%, with the highest active response rate observed for "intentionally hugging or kissing the opposite sex" (39.7%). Conclusions The special education schools in Luzhou lack comprehensive sex education curricula, teaching materials and full time teachers, sufficient knowledge among teachers, and adequate proactive responses to students inappropriate sexual behaviors. Greater emphasis should be placed on sex education for special children, including the training of dedicated teachers, to provide comprehensive and high quality sex education services for special children.

Objective: To investigate the changing trends for associations of anxiety and depressive symptoms with smartphone addiction among middle school students, so as to provide a scientific basis for preventing smartphone addiction in middle school students. Methods: From 2022 to 2023, a method of combining convenient sampling with cluster sampling was used to select 8 923 middle school students from 27 junior high schools and 3 senior high schools in a district of Shenzhen City between September 2022 (baseline, T1) and September 2023 (follow up, T2). The Smartphone Addiction Scale-Short Version (SAS-SV), Patients Health Questionnaire-9 Item (PHQ-9), and Generalized Anxiety Disorder 7-item Scale (GAD-7) were administered to assess smartphone addiction, anxiety and depressive symptoms. Mixed effects models were used to analyze the association of anxiety and depressive symptoms with smartphone addiction among middle school students. Results: From September 2022 to September 2023, the reported prevalence of smartphone addiction increased from 24.22% to 25.25% ( χ 2=45.71); and smartphone addiction scores [ 24.00 (16.00, 32.00),25.00(16.00, 33.00)], anxiety symptom scores [2.00(0.00, 7.00),3.00(0.00, 7.00)] and depressive symptom scores[3.00(0.00, 8.00),5.00(0.00, 9.00)] all significantly increased ( Z =-17.43, -42.38, -41.57) (all P <0.05). There were statistically significant difference in the distribution of anxiety and depression symptom levels among middle school students in 2022 and 2023 ( χ 2=85.15, 106.85, both P <0.05). After adjusting for covariates such as age, gender and family background, mixed effects models revealed dose response associations of anxiety and depressive symptoms with smartphone addiction among middle school students:mild anxiety symptom( OR =3.22), moderate to severe anxiety symptom ( OR =5.36), mild depressive symptom ( OR =3.32) and moderate to severe depressive symptom ( OR =6.13) were significantly associated with higher risks of smartphone addiction (all P <0.05). Interaction effect analysis found that co existing anxiety and depressive symptoms synergistically increased addiction risk by 5.60 times ( OR =5.60) compared to the asymptomatic group, with 32% of the combined risk attributable to their interaction ( S=1.64, AP =0.32)(both P < 0.05 ). Conclusions Anxiety and depressive symptoms are significantly associated with smartphone addiction, exhibiting a synergistic effect. Attention should be paid to emotional issues and smartphone addiction among middle school students.

ObjectiveTo analyze the correlation between the clinical symptoms， signs， syndrome characteristics and laboratory indicators of cough variant asthma （CVA） and deepen the understanding of the treatment of this disease based on the theory of "Fu Feng". MethodsAn observational study was conducted. A total of 207 CVA patients who visited the respiratory department of the Third Affiliated Hospital of Beijing University of Chinese Medicine from September 2022 to November 2023 were included. The information from the four diagnostic methods and the laboratory test results of patients were collected. Factor analysis was conducted on the information obtained through the four diagnostic methods in TCM， and the nature and location of CVA were extracted. Sample cluster analysis （Q clustering） and the K-means method were used for data clustering analysis to determine the syndrome types of CVA and analyze the syndrome characteristics and differences in laboratory indicators among different syndrome types. ResultsThe main symptom of CVA patients was cough， accompanied by symptoms such as itchy throat， foreign body sensation in the throat， dry throat， shortness of breath， dry mouth， chest tightness， hoarseness， bitter mouth， poor appetite， and skin itching. Factor analysis showed that the disease was located in the lung， involving the liver， spleen， and kidney. The pathological factors involved Yin deficiency， Yang deficiency， wind factor， dampness factor， Yin factor， and Qi stagnation. Cluster analysis revealed four syndrome types： Fengfu Yinshang syndrome， Shixie Neiyun syndrome， Tanyin Zufei syndrome， and Ganhuo Fanfei syndrome. Fengfu Yinshang syndrome accounted for the highest proportion， followed by Tanyin Zufei syndrome. There were no significant differences in eosinophil count and percentage， fractional nasal nitric oxide （FnNO） level， and pulmonary function indexes among the four syndromes. The levels of serum total IgE and fractional exhaled nitric oxide （FeNO） in patients with Fengfu Yinshang syndrome were significantly higher than those in patients with Shixie Neiyun syndrome and Tanyin Zufeisyndrome. ConclusionCough is the main symptom of CVA， accompanied by pharyngeal itching， foreign body sensation in the throat， dry throat， shortness of breath， dry mouth， and allergic manifestations. The disease involves the lung， liver， spleen， and kidneys. The essence of the pathogenesis lies in a latent dormant pathogen and a disorder of the pivot mechanism. The four common syndrome types are Fengfu Yinshang syndrome， Shixie Neiyun syndrome， Tanyin Zufei syndrome， and Ganhuo Fanfei syndrome. The TCM syndrome types are correlated with laboratory indexes. The serum total IgE and FeNO of patients with Fengfu Yinshang syndrome are worse.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Inflammation is a key player in various pathophysiological processes and diseases, especially throughout the gestational cycle, and inflammation plays an important role in ovulation, embryo implantation, placental formation, and all stages of pregnancy maintenance. However, excessive inflammatory activity can impair endometrial receptivity, which can lead to clinical problems such as infertility, recurrent implantation failure, and recurrent miscarriage, which in turn can negatively impact women's reproductive health and pregnancy outcomes. Studies have shown that about two-thirds of embryo implantation failures are associated with inadequate endometrial receptivity. Therefore, the precise regulation of inflammatory states is of great significance for increasing pregnancy rates and improving pregnancy outcomes.

Cassiae Semen is a substance with both edible and medicinal uses approved by the National Health Administration， and it is widely used in health food products in China. In this study， an information database of Cassiae Semen-based health food products was constructed， and the common patterns of functional claims， major raw materials， and dosage forms were analyzed.

Secondly， based on the positioning and regulatory requirements of health food and the recent research progress in Cassiae Semen， this paper analyzed the problems in technology review and product development from safety， function claim， and quality controllability. Finally， suggestions were put forward to promote the inheritance and carry forward China's traditional healthcare culture and the achievement of the Healthy China Initiative. These suggestions included classifying and optimizing the access management of health food， innovating the traditional healthcare function claims， and strengthening the quality system construction and information disclosure of post-marketing evaluation.

OBJECTIVE To evaluate the economics of trastuzumab deruxtecan versus the physician-selected chemotherapy （TPC） regimen in the second-line treatment of advanced breast cancer with epidermal growth factor receptor 2 （HER-2） low expression from the perspective of the Chinese healthcare system. METHODS Based on the data of DESTINY-Breast04 clinical trial， the dynamic Markov model was constructed. The time frame of the model simulation was 10 years， and the cycle was 3 weeks. Taking cost， quality-adjusted life year （QALY） and incremental cost-effectiveness ratio （ICER） as the model output indicators， the discount rate of 5% was applied， and 3 times China’s per capita gross domestic product （GDP） in 2023 was taken as the willingness-to-pay （WTP） threshold value. Cost-utility analysis was used to evaluate the economics of the two treatment regiments in the hormone receptor-positive cohort and all patient cohorts， and uncertainty analysis was used to verify the robustness of the basic analysis result. RESULTS The results of the basic analysis showed that compared with the TPC regimen， the ICER value of trastuzumab deruxtecan regimen edu.cn were 1 045 655.76 and 906 404.99 yuan/QALY in the hormone receptor-positive cohort and all patients， respectively， both exceeding the WTP threshold （268 074 yuan/QALY）. The results of single factor sensitivity analysis showed that progression-free survival utility value， the price of trastuzumab deruxtecan and progression disease utility had a significant influence on the model results. The results of probability sensitivity analysis showed that when the WTP threshold was 3 times China’s per capita GDP in 2023， the probability of economic viability of trastuzumab deruxtecan was 0. The results of scenario analysis showed that when the patient assistance program for trastuzumab deruxtecan was considered， the probability of trastuzumab deruxtecan regimen being economical was 0. However， when the price of trastuzumab deruxtecan was reduced by 70%， the probability of its being cost-effective was significantly increased to 82.80%. CONCLUSIONS At a WTP threshold of 3 times China’s per capita GDP in 2023， the trastuzumab deruxtecan regimen is not cost-effective compared to TPC regimen for the second-line treatment of advanced breast cancer with HER-2 low expression. Reducing the price of trastuzumab deruxtecan by region can improve its cost-effectiveness.

Objective To analyse the concept of subjective financial distress in cancer patients.Methods Papers in regarding the subjective financial distress were retrieved from the databases such as China National Knowledge Infrastructure(CNKI),Wangfang Database,PubMed,Cochrane Library,Web of Science,CINAHL,and Embase from the inceptions to 16th October,2022.Walker and Avant's concept analysis was performed to analyse the acquired articles.Results A total of 48 articles were retrieved and included in the study.Walker and Avant's concept analysis showed that the subjective financial distress in the patients was subject to the 3 defining attributes:perceived economic risk,coping behaviours,and negative emotional reactions.The antecedents of this distress included individual factors,disease and treatment factors,and social factors.The consequences of them were the increase in negative health behaviours and poorer quality of life.Conclusions The attributes,antecedents and consequences of subjective financial distress,as identified through the conceptual analysis,can serve as a reference for subsequent researches.In future studies,it would be beneficial by further exploring the connotation by considering China's healthcare system.
