Objective To investigate the association between low-level ionizing radiation exposure and peripheral blood parameters in medical radiation workers, and to provide evidence for radiation protection strategies and occupational health surveillance. Methods A total of 1261 medical radiation workers from medical institutions in Heze City, Shandong Province, China, were enrolled. Individual monitoring of occupational external exposure was performed. Demographic characteristics and physical examination data were collected. According to the median annual effective dose, the subjects were stratified into a low-dose group (0.10-0.43 mSv) and a high-dose group (>0.43-5.24 mSv). Logistic regression was used to assess the association between ionizing radiation and peripheral blood parameters. Subgroup analyses were conducted by gender, age, and exposure duration. Results A total of 1261 subjects were enrolled, of whom 893 (70.82%) were male and 368 (29.18%) were female. The median age was 39.00 (32.00, 47.00) years and the median exposure duration was 11.00 (5.00, 22.00) years. No statistically significant differences in baseline characteristics were observed between the two groups. The radiation dose ranged from 0.104 to 5.239 mSv, all below the occupational exposure limit (20 mSv). Basophil count, hematocrit, and mean corpuscular volume in the high-dose group were significantly higher than those in the low-dose group, while mean corpuscular hemoglobin concentration was lower (P<0.05). Logistic regression analysis showed that ionizing radiation primarily affected erythrocyte parameters, with abnormal hematocrit (OR=1.449, 95%CI: 1.148-1.831), abnormal mean corpuscular volume (OR=1.407, 95%CI: 1.119-1.771), and abnormal mean corpuscular hemoglobin concentration (OR=1.608, 95%CI: 1.278-2.025) positively associated with ionizing radiation exposure. Subgroup analyses further revealed differences that were not observed in the total population These findings suggest that gender, age, and exposure duration may modify the effect of ionizing radiation on peripheral blood parameters. Conclusion Long-term low-level ionizing radiation exposure can affect peripheral blood parameters in medical radiation workers, particularly erythrocyte parameters. Enhanced occupational health monitoring and protection measures are warranted.

ObjectiveTo evaluate the clinical efficacy of Huangqin Qingre Chubi capsules （HQC） in patients with rheumatoid arthritis （RA） and the syndrome of dampness-heat obstruction and investigate the mechanism by which HQC restore clinical and laboratory parameters in RA patients through regulation of the long non-coding RNA （LncRNA） endogenous Bornavirus-like nucleoprotein 3 pseudogene （EBLN3P）/miR-369-3p/nuclear factor I X（NFIX）-Janus kinase（JAK）/signal transducer and activator of transcription （STAT） signaling pathway，thereby providing new experimental evidence and potential therapeutic targets for the traditional Chinese medicine （TCM） treatment of RA. MethodsA randomized controlled trial design was adopted，with 100 RA patients meeting the criteria assigned into an observation group （n=50） and a control group （n=50）. In addition，50 healthy controls were enrolled. The control group received leflunomide plus meloxicam，while the observation group additionally received HQC. Efficacy was assessed after 4 weeks of treatment. Observation indicators including Western medicine indicators （DAS28，CPRI-RA，SF-36，VAS，PGA，PhGA，and SAS/SDS），TCM syndrome scores （TCMSS-RADHP，TCMSS-RASDP），and laboratory indicators （ESR，CRP，RF，anti-CCP antibody，VEGF，bFGF，MMP-2/9，p-JAK2/STAT3，and LncRNA EBLN3P/miR-369-3p/NFIX expression） were measured to comprehensively explore the therapeutic mechanism of HQC. ResultsThe study included 45 healthy controls （34 males and 11 females） and 87 RA patients （22 males and 65 females）. The median age，median disease duration，and median BMI of patients were 56 years old，10 years，and 21.51 kg·m^-2，respectively. Compared with healthy controls，the RA group exhibited a typical state of immune-inflammatory activation as manifested by elevated levels of ESR，anti-CCP antibodies，CRP，and RF （P<0.01），raised clinical symptom scores （DAS28，VAS，PGA，PhGA，CPRI-RA，and TCM symptoms） （P<0.05，P<0.01），and reduced SF-36 domain scores （P<0.01）. Molecular detection revealed abnormal expression of LncRNA EBLN3P and miR-369-3p，upregulated expression of key proteins in the JAK/STAT pathway （JAK2/p-JAK2 and STAT3/p-STAT3） and angiogenesis markers （VEGF，bFGF，and MMP-2/9），and downregulated expression of NFIX （P<0.05，P<0.01） in the RA group. Spearman correlation analysis further demonstrated associations of key molecules in the LncRNA EBLN3P/miR-369-3p/NFIX-JAK/STAT pathway with immune-inflammatory markers and clinical symptom scores （P<0.05，P<0.01）. Regarding treatment response，both groups showed reductions in ESR，anti-CCP，CRP，and RF levels compared with baseline （P<0.01） and restored scores of DAS28，CPRI-RA，VAS，PGA，PhGA，TCM symptoms，SAS，SDS，and all SF-36 domains （P<0.01）. The observation group outperformed the control group in restoring the scores of SAS，SDS，PGA，TCMSS-SDP，and SF-36 domains （PF，BP，GH，VT，and SF） （P<0.05）. Real-time PCR analysis revealed that post-treatment expression levels of LncRNA EBLN3P，miR-369-3p，NFIX，JAK2，p-JAK2，STAT3，p-STAT3，VEGF，bFGF，MMP-2，and MMP-9 were recovered compared with pre-treatment levels （P<0.01）. Notably，the observation group demonstrated superior regulatory effects on p-JAK2，STAT3，p-STAT3，and MMP-9 compared with the control group （P<0.05）. Apriori association rule analysis revealed that HQC treatment was significantly correlated with reduced TCMSS-RADHP，ESR，SF，DAS28，SAS，and SDS scores，as well as increased VT，GH，and RP scores （confidence >80%，support >50%）. Regarding safety，two patients in the observation group experienced mild gastrointestinal discomfort，and one patient in the control group developed a rash. All the symptoms resolved after symptomatic treatment. ConclusionHQC target and regulate the LncRNA EBLN3P/miR-369-3p/NFIX-JAK/STAT axis to inhibit angiogenesis and inflammatory responses，reduce immune inflammatory markers，alleviate clinical symptoms，and improve the quality of life in RA patients，exerting synergistic effects on symptoms and quality of life.

OBJECTIVES: To investigate the regulatory effect of LINC00837/miR-671-5p/SERPINE2 functional axis on pathological processes of fibroblast-like synovial cells (FLS) in rheumatoid arthritis (RA). METHODS: RA-FLS were transfected with a LINC00837 overexpression plasmid (pcDNA3.1-LINC00837), a LINC00837 interference plasmid (siRNA-LINC00837), or their respective negative control plasmids (pcDNA3.1-NC and siRNA-NC). Dual luciferase was used to verify the targeting relationship between LINC00837 and miR-671-5p and between miR-671-5p and SERPINE2. RT-qPCR was used to detect the expression levels of LINC00837, miR-671-5p and SERPINE2 in normal FLS or the transfected cells, whose proliferation and migration abilities were assessed using Edu assay and scratch healing assay and by detecting the expression levels of Ki-67, PCNA, E-cadherin and N-cadherin with Western blotting. The changes in cellular secretion of the inflammatory cytokines (TNF‑α, IL-17, IL-4 and IL-10) were examined using ELISA. RESULTS: Dual luciferase reporter gene assay showed that LINC00837 was capable of binding to the 3'-UTR of miR-671-5p, and the latter bound to the 3-UTR of SERPINE2 at specific binding sites between them. Compared with normal FLS, RA-FLS showed significantly increased expressions of LINC00837 and SERPINE2, lowered miR-671-5p expression and enhanced proliferation and migration abilities with increased expressions of pro-inflammatory cytokines and reduced expressions of anti-inflammatory cytokines. Transfection of RA-FLS with pcDNA-LINC00837 further enhanced cell proliferation and migration and the changes in the inflammatory cytokines, while transfection with si-LINC00837 produced the opposite changes. CONCLUSIONS RA-FLS have a LINC00837/miR-671-5p/SERPINE2 functional axis, which regulates cell proliferation, migration and secretion of inflammatory factors, and interventions targeting LINC00837 may provide a potential strategy to regulate the pathological processes in RA-FLS.

Objective: To explore the relationship between processed food consumption and blood pressure level of students in a university in Yunnan Province, so as to provide the reference for preventing hypertension in university students. Methods: In October 2021, a cluster sampling method was used to select 4 781 freshmen from a university in Kunming, Yunnan Province. The frequency of processed food consumption of university students was assessed by using the dietary frequency questionnaire, and height, weight and blood pressure were measured. Mann-Whitney test and Kruskal-Wallis test were used to compare the differences in blood pressure level of university students with different demographic variables, and the association between processed food consumption and blood pressure level was analyzed with a generalized linear model. Results: Among the students of a university in Yunnan Province, the detection rates of systolic prehypertension and hypertension were 33.86% and 1.23%, and the detection rates of diastolic prehypertension were 32.13% and hypertension 7.22%. The results of generalized linear model analysis showed that after controlling for demographic variables and other variables that might affect the blood pressure level of university students, the consumption of processed food (bread and cake: β =0.15, 95% CI =0.01-0.29) and ultra processed food (coffee beverage: β =-0.29, 95% CI =-0.54--0.03) were associated with systolic blood pressure level( P <0.05). The consumption of processed food (salted duck egg: β =0.21, 95% CI =0.01-0.41) was correlated with the diastolic blood pressure of college students ( P <0.05). Conclusions Processed food consumption in university students may increase the risk of high blood pressure.The education of healthy eating among college students should be strengthened to reduce the consumption of processed foods.
