Objective:To study investigates the current healthcare-seeking status of patients with pneumoconiosis at grassroots rehabilitation stations in Henan Province, analyzes their healthcare-seeking behaviors and influencing factors, and provides references for formulating relevant rehabilitation treatment and health management policies.Methods:In July 2024, a total of 492 cases of pneumoconiosis patients registered at 7 grassroots pneumoconiosis rehabilitation stations from July to December 2021 were selected. The "Healthcare-Seeking Behavior and Influencing Factors of Pneumoconiosis Patients" questionnaire was used to collect information through a combination of rehabilitation station consultations and household interviews. Data on medical insurance type, whether the employer had purchased work-related injury insurance, patient condition characteristics (years of dust exposure, pneumoconiosis stage, patient condition score) , and reasons for not visiting rehabilitation stations were gathered and statistically analyzed. Univariate analysis was conducted using the chi-square test and logistic regression analysis was used to identify the influencing factors of patients' medical-seeking behavior.Results:A total of 492 pneumoconiosis patients were registered in basic rehabilitation stations in Henan Province. Among them, 204 cases (41.5%) went to the rehabilitation station, In the past year, 288 cases (58.5%) did not visit. Patients with pneumoconiosis who have no income, whose employer has purchased work-related injury insurance, whose pneumoconiosis type is silicosis, and whose disease score is 15-20 points have a high rate of visits to rehabilitation stations ( OR=8.35, 95% CI: 4.40-15.84; OR=13.89, 95% CI: 7.69-25.08; OR=3.20, 95% CI: 1.18-8.68; OR=5.18, 95% CI: 2.04-13.14) . The top five reasons for the analysis of not visiting were: the self-induction symptoms lighter (58.7%, 169/288) , online consultation or telephone follow-up (17.0%, 49/288) , buying medicine in a drugstore (14.6%, 42/288) , thinking of seeing a doctor is useless, can not be cured (6.9%, 20/288) , medical expenses are high and cannot be reimbursed (6.3%, 18/288) . Conclusion:Economically disadvantaged silicosis patients with work-related injury insurance and severe conditions prefer seeking treatment at nearby rehabilitation stations. The main reasons for reluctance to seek medical care are low treatment demand and concerns over high costs. Greater attention should be paid to the demand of pneumoconiosis patients for "Internet+healthcare" services at grassroots-level rehabilitation stations.

OBJECTIVE To improve the quality standard of Zhuang medicine Yingbupu （Aralia armata）. METHODS A total of 23 batches of Yingbupu （A. armata） were studied. Their macroscopic characteristics and powder microscopic features were observed. TLC was employed for the qualitative identification of oleanolic acid and araloside A. Items such as water content， total ash， acid-insoluble ash， and ethanol-soluble extract were determined according to the methods specified in the 2020 edition of the Chinese Pharmacopoeia （part Ⅳ）. UPLC fingerprint was established for 23 batches of samples by using Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicine （2012 edition）， and the contents of oleanolic acid and araloside A were determined. RESULTS The powder microscopic characteristics of the medicinal material were distinctive. Oleanolic acid and araloside A were detected by TLC in all 23 batches. Among the 23 batches of samples， the content ranges of moisture， total ash， acid-insoluble ash， and ethanol-soluble extract were 6.9% to 10.4%， 1.8% to 6.8%， 0.1% to 1.9%， and 2.8% to 8.4%， respectively. Based on the UPLC fingerprint， a total of 15 common peaks were obtained， and 9 of these common peaks were identified. The content ranges of oleanolic acid and araloside A in the 23 batches of samples were 0.86% to 2.69% and 0.16% to 1.10%， respectively. CONCLUSIONS This study has added items such as moisture and total ash content fingerprint， TLC identification. A preliminary quality standard has been established for the medicinal material of Yingbupu （A. armata）， stipulating that the moisture content should not exceed 11.0%， the total ash content should not exceed 5.0%， the acid-insoluble ash content should not exceed 2.5%， the ethanol-soluble extract（No. content should not be less than 4.0%， and the contents of zyyzdxk-2023165） oleanolic acid and araloside A should not be less than 1.00% and 0.45%（ calculated by a dried basis）， respectively.

OBJECTIVE To investigate the anti-inflammatory effects and mechanism of Zhuang medicine Tongfeng li’an capsules on gouty arthritis in combination with in vivo and in vitro experiments. METHODS Sixty rats were randomly divided into normal group， model group， positive control group （27 mg/kg allopurinol+0.27 mg/kg colchicine）， Tongfeng li’an capsules low- dose， medium-dose and high-dose groups （2.2， 4.5， 9.0 g/kg）， with 10 rats in each group. Except for normal group， gouty arthritis model of rats was induced in other groups. Rats in each administration group were given corresponding drugs intragastrically， and rats in the normal group and model group were given equal volume of water intragastrically for 14 consecutive days. The degree of ankle joint swelling， serum level of interleukin-1β （IL-1β） and protein expressions of nuclear factor kappa-B （NF-κB） in synovial tissue were detected， and the histopathological changes of synovium tissue in the ankle joint of rats were observed. The inflammation model was established by stimulating RAW264.7 cells with lipopolysaccharide. After Tongfeng li’an capsules （62.5， 125， 250 μg/mL） were given， the levels of nitric oxide （NO）， reactive oxygen species （ROS） and IL-1β in the cells and protein expression of NF-κB were detected， and NF-κB localization in the cells was also determined. RESULTS Results of in vivo experiment showed that compared with normal group， the swelling degree of the ankle joint， serum IL-1β level and protein expression of NF-κB in synovium tissue were all increased significantly in model group （P＜0.05）； pathological changes such as synovial hyperplasia， edema， vascular congestion， capillary hyperplasia， and increased inflammatory cells were observed. Compared with model group， the levels of above indexes were all decreased significantly in Tongfeng li’an capsules high-dose group （P＜0.05）， and most of the above indexes were significantly reduced in Tongfeng li’an capsules medium-dose and low-dose groups （P＜0.05）； synovial hyperplasia of the ankle joint improved， and the infiltration of inflammatory cells 2019BS044） decreased. Results of in vitro experiment showed that Tongfeng li’an capsule could significantly reduce the levels of NO， ROS and IL-1β and protein expression of NF-κB（P＜0.01）， and inhibit NF- κB nucleation. CONCLUSIONS Tongfeng li’ancapsules have good anti-inflammatory effect on gouty arthritis， and its mechanism may be related to the inhibition of NF-κB signaling pathway activity.

The special occupational health surveillance for workers exposed to mycobacterium tuberculosis and hepatitis virus is removed. The OME conclusion of reexamination is removed, and standardize recheck/additional inspection requirements. The optional items in OME performed before, during and after leaving post are removed, but the optional items in emergency medical examination are retained. Additional OME items are added. The Guideline for OME Summary Reports is added as informative appendix, and so on. The revised GBZ 188 Technical Specification for Occupational Health Surveillance is more scientific and practical.

Objective: To evaluate the utilization and influencing factors of whole lung lavage (WLL) for patients with pneumoconiosis. Methods: A total of 10 524 pneumoconiosis patients who sought medical treatment from 2018 to 2021 were selected as the research subjects using a combination of stratified random sampling and non-random sampling methods. The patients were from 27 provincial administrative regions of Chinese mainland (excluding Shanghai City, Tianjin City, Hainan Province and Tibet Autonomous Region). The effects of demographic and sociological characteristics, disease-related factors, and economic and social security status on WLL utilization were analyzed. Results: The WLL rate of pneumoconiosis patients was 17.8% (1 871/10 524). The main reason for promoting WLL in pneumoconiosis patients was “doctor's advice”, accounting for 65.4%； followed by “known-pneumoconiosis-patients had WLL” and “patient's recommendation”, accounting for 24.1% and 18.1%, respectively. Multivariate logistic regression analysis showed that age, body mass index, smoking index, education level, survey area, source of patients, current employment status, nature of dust-exposed unit, stage of pneumoconiosis, type of pneumoconiosis, pneumoconiosis symptoms (coughing up phlegm, chest pain, dyspnea, joint pain), contraindications to WLL (tuberculosis, pulmonary heart disease), family annual income, medical insurance for urban employees, proportion of medical insurance reimbursement, disability benefits, and social assistance were the influencing factors of WLL utilization in pneumoconiosis patients (all P<0.05). Conclusion: A large proportion of pneumoconiosis patients used WLL. The influencing factors of WLL utilization included demographic and sociological characteristics, disease-related factors, economic and social security status, and more. It is necessary to protect the interests of pneumoconiosis patients, strengthen occupational health education and health promotion for pneumoconiosis patients, standardize the use of WLL in medical institutions, and make rational use of WLL.

Background::Patients with pneumoconiosis have an elevated risk of contracting pulmonary tuberculosis (PTB) and need particular attention. However, extensive population-based studies on the prevalence of PTB in patients with pneumoconiosis have not been reported in China since 1992. This study aimed to investigate the epidemiological characteristics of PTB in patients with pneumoconiosis based on its social determinants and risk factors in China.Methods::Based on the Commission on Social Determinants of Health (CSDH) framework, data were obtained from a questionnaire survey of patients with pneumoconiosis from China’s 27 provinces (autonomous regions, municipalities) from December 2017 to June 2021. By chi-square and multivariate logistic regression analyses, the epidemiological characteristics of PTB in the patients were identified based on its prevalence and odds ratio (OR) and associated social determinants and risk factors. The population attributable fractions (PAFs) of significant risk factors were also calculated.Results::The prevalence of PTB in patients with pneumoconiosis ( n = 10,137) was 7.5% (95% confidence interval [CI]: 7.0-8.0%). Multivariate logistic regression analysis showed that risk factors included in-hospital exposure to patients with PTB (OR = 3.30, 95% CI: 2.77-3.93), clinically diagnosed cases (OR = 3.25, 95% CI: 2.42-4.34), and northeastern regions (OR = 2.41, 95% CI: 1.76-3.31). In addition, lack of work-related injury insurance (WRII), being born in a rural area, being unemployed, living in western regions, household exposure to patients with PTB, smoking, being underweight, complications of pulmonary bullae or pneumothorax, hospitalization history, and former drinkers among the rural patients were also statistically significant risk factors. Being born in a rural area, lack of WRII and in-hospital exposure to patients with PTB had higher PAFs, which were 13.2% (95% CI: 7.9-18.5%), 12.5% (95% CI: 8.3-16.7%), and 11.6% (95% CI: 8.8-14.3%), respectively. Conclusion::The prevalence of PTB in pneumoconiosis remains high in China; it is basically in line with the CSDH models and has its characteristics.

Objective:To investigate the therapeutic effects of leflunomide on salivary gland secretion hypofunction in NOD mice with Sjogren′s syndrome.Methods:NOD mice were randomly divided into four groups: prevention group, prevention control group, treatment group and treatment control group. Salivary flow rate was measured after pilocarpine stimulation. Changes in the average number and area of infiltrating lesions were compared after hematoxylin and eosin (HE) staining. The percentages of CD3 + T, CD4 + T, CD8 + T, CD44 + CD62L -CD4 + T, CD19 + B and CD138 + B cells in submandibular gland and spleen were detected by flow cytometry. The levels of TNF-α, IL-17A and IL-6 in serum were detected by CBA method. Results:The salivary flow rate ( t=-5.81, P<0.001; t=-3.61, P<0.05), the number of infiltrating lesions( t=3.95, P<0.01; t=4.94, P<0.001)and the average area of infiltrating lesions( t=3.18, P<0.05; t=2.35, P<0.05)were significantly ameliorated in the prevention and treatment groups. Moreover, CD3 + CD4 + T cells( t=2.39, P<0.05; t=3.82, P<0.01)and CD44 + CD62L -CD4 + T cells( t=3.53, P<0.05; t=3.36, P<0.05)in the submandibular gland were significantly decreased. CD3 + T( t=6.08, P<0.001; t=2.76, P<0.05), CD3 + CD4 + T ( t=3.73, P<0.05; t=2.39, P<0.05), CD19 + B ( t=5.88, P<0.001; t=4.23, P<0.01) and CD138 + B cells ( t=4.30, P<0.001; t=4.46, P<0.01) in the spleen were also significantly reduced. Serum IL-17A ( t=4.15, P<0.01; t=3.36, P<0.01) in the two groups and TNF-α ( t=4.56, P<0.001) in the prevention group were down-regulated, but no significant difference was observed in IL-6 level. Conclusions:This study suggested that leflunomide could prevent and improve salivary gland hypofunction and inhibit immune activation in NOD mice, providing reference for evaluating leflunomide in the treatment of Sjogren′s syndrome.

Objective:To investigate the expression of B lymphocyte induced maturation protein 1 (Blimp-1) in peripheral blood CD4 + T cells, CD19 + B cells and labial glands of patients with primary Sj?gren′s syndrome (pSS) and the correlation of Blimp-1 with clinical features. Methods:Expression of PRDM1 at mRNA level in CD4 + T cells, CD19 + B cells and labial gland tissues were detected by RT-PCR. Immunohistochemistry (IHC) was used to observe the distribution of Blimp-1. Correlation of PRDM1 expression at mRNA level with clinical indicators was analyzed. Results:PRDM1 expression at mRNA level in CD4 + T and CD19 + B cells were significantly higher in pSS group than in healthy control (HC) group ( P<0.01). Based on European League Against Rheumatism Sj?gren′s Syndrome Disease Activity Index (ESSDAI), the patients were classified into two groups: active group (ESSDAI≥5) and inactive group (ESSDAI<5). PRDM1 expression at mRNA level in CD4 + T and CD19 + B cells were also higher in the active group than in inactive group ( P<0.05). Blimp-1 protein accumulated around the acinus and duct of labial gland and in the germinal center in pSS patients. PRDM1 expression at mRNA level in labial gland tissues of pSS patients was positively correlated with lymphocyte infiltration ( r=0.781, P<0.001). Conclusions:pSS displayed high expression of Blimp-1. Blimp-1 might affect pSS disease activity and have clinical significance in pSS treatment.
