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.

To revise GBZ 188 Technical Specification for Occupational Health Surveillance based on national laws, regulations, standards, specifications and legal documents of occupational disease, and combination with the actual situation in China. The main modifications are as follows: the occupational health surveillance for workers exposed to toluene (xylene may implement by reference), bromopropane, methyl iodide, ethylene oxide, chloroacetic acid, indium and its compounds, coal tar, coal tarasphalt, asphalt, β-naphthylamine, dust of metal and its compounds(tin, iron, antimony, barium and its compounds), hard metal dust, erionite dust, low temperature, laser, tick-borne encephalitis virus, Borrelia burgdorferi, and human immunodeficiency virus, for scraper or grind operators, and underground workers using squatting or kneeling position, crawling position, side-lying position, or shoulder position for a long period of time are included. The emergency health screening for workers exposed to arsenic, fluorine and its inorganic compounds, and acrylamide are included. The occupational medical examination (OME) for workers exposed to amino and nitro compounds of benzene, phosgene, monomethylamine, organic fluorine and dimethyl sulfate has been adjusted and made mandatory, with corresponding assessments required upon leaving the job. 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.

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.

Objective To investigate the change and significance of regulatory T cells (Tregs) in peripheral blood in patients with acute and chronic gout. Methods Flow cytometry was used to detect the ratio of Tregs in peripheral blood of healthy controls, patients with acute gout and patients with chronic gout. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of transforming growth factor (TGF)-βand interleukin (IL)-1βin plasma. Then, statistical analysis was conducted to analyze the changes and significance in different stages of gout, such as F test, Kruskal-Walls H test, q test and Pearson and Spearman correlation analysis. Results ① The percentage of CD4+CD25+Foxp+Treg/CD4+ T cells in peripheral blood was (1.22±0.27)% in control group. While in patients with acute gout, it was (1.51±0.43)%, and (0.47±0.26)%in patients with chronic gout. There were statistical significant difference among the three groups ( F=101.39, P<0.05). The percentage of Tregs in acute gout group was significantly higher than that in control group and chronic gout group, while it was significantly lower in chronic gout group than in control group ( P<0.05). ②The concentration of TGF-β in plasma was (170 ±12) ng/L in control group, (214 ±77) ng/L in patients with acute gout and (179±21) ng/L in patients with chronic gout, the difference was statistically-significant (F=6.20, P<0.05). The concentration of TGF-β in plasma in acute gout group was significantly higher than the control group and chronic gout group, the difference was statistically significant (P<0.05), while the difference between chronic gout group and the control group was not statistically significant ( P>0.05). ③The con-centration of IL-1β in plasma in the control group was (4.8 ±1.3) ng/L, while that in patients with acute and chronic gout was (10.1±8.5) ng/L and (11.50±12.57) ng/L respectively, the difference between these three groupswas stati-sticallysignificant (P<0.05). The concentration of IL-1β in plasma in acute gout group and chronic gout group wassignificantly higher than that in the control group, the difference was statistical significant ( P<0.05). There was no significant difference between acute gout and chronic gout (P>0.05) patients. ④ The percentage of Tregs in peripheral blood of gout patients was negatively correlated with the duration of disease and the number of gout attacks within six months (duration of disease: r =-0.381, P <0.01 ; number of gout attacks: r=-0.518, P<0.01). But there wasno significant correlation to the concentration of TGF-β and IL-1β. Conclusion Tregsincreasesin acute gout and participate in the alleviation of gout inflammation, while the persistence of chronic gout may be related to the decrease of Tregs. Therefore, Tregs play an important regulatory role in the transformation of acute and chronic gout.

Objective:
To study the causes and influencing factors of no seeking medical treatment among pneumoconiosis patients.
Methods:
Using stratified sampling method and typical survey method, we carried out the questionnaire survey in nine provinces in China including the east, the medium and the western region using a questionnaire on the seeking medical behavior pf pneumoconiosis patients and the influencing factors. The subjects include occupational pneumoconiosis cases and clinically diagnosed cases and the response rate is 94.3 percent. The data was entered twice with epidate3.1 and error detection and statistical analysis was completed with SPSS 20.0. Chi-square test was used for univariate analysis, and multivariate logistic regression was used for multivariate analysis.
Results:
One thousand and thirty-seven subjects were investigated with average age 55.9±11.2 years. Seventy percent of them were silicosis and 21.9 percent were coal worker’s pneumoconiosis with 67.5 percent of them residing permanently in the countryside, and 37.9 percent of their education background were primary school culture and 33.1 percent of them had junior high school culture. Thirty two point six percent of respondents had no personal income with a median monthly income of 1 200 yuan. Four hundred and thirty four of subjects hadn't seek medical treatment since they got the pneumoconiosis accounting for 41.9 percent with three hundred and thirty seven of them hospitalized directly. The reasons of no seeking medical treatment for the respondents mainly include the self-induction symptoms lighter, the high cost of treatment and cannot claiming the payment of the medical expenses, buying drugs in drugstore, thinking that no medicine can cure pneumoconiosis or no effect, complex procedures, too far away from medical institutions, no unaccompanied, needing a long time or no time, communication disorders, etc. accounting for 44.4 percent, 24.6 percent, 10.9 percent, 9.1 percent, 6.9 percent, 4.4percent, 3.2 percent, 2.9 percent, 1.9 percent, 1.5 percent, respectively. The results of multivariate analysis showed the main characteristics of subjects with restrictions to the outpatient health service utilization are as follows: demographic sociological indicators such as registered permanent residence area is western (
