Objective: To analyze the demographic characteristics, return donation patterns, and risk of adverse reactions among donors temporarily deferred due to blood pressure abnormalities, so as to provide an evidence-based foundation for optimizing pre-donation blood pressure screening strategies, enhancing donor retention, and ensuring blood supply safety. Methods: Data from 2.939 million donor instances were collected through the Information Management System at the Beijing Red Cross Blood Center between January 2015 and August 2025. The analysis specifically focused on the 11 600 instances of donors temporarily deferred due to abnormal blood pressure, examining demographic characteristics (age, and gender) and donation-related features (number of donations, donation site, and type of donation). Further analysis was conducted on the return donation patterns, including the return rate, time interval to return, and the incidence, type, and severity of adverse reactions among returned donors. Results: Distribution of abnormal blood pressure: Among the 11 600 instances of abnormal blood pressure, the prevalence was significantly higher in males (0.48%, 10 111/2 086 909) than in females (0.17%, 1 465/852 090). The 46-55 age group had the highest prevalence (0.88%, 2 925/329 235), and the differences across age groups were statistically significant. The prevalence was, higher among repeat donors (0.41%, 5 242/1 276 452) than first-time donors (0.38%, 6 334/1 662 547). The prevalence at mobile donation sites outside the blood center (0.06%, 350/596 104) was higher than fixed donor centers (0.50%, 10 225/2 052 290) and group donation drives (0.34%, 1 001/290 608). Return donations: A total of 19.49% (2 256 out of 11 576) deferred donors returner and successfully donated. Among these donors, 36.17% (816 out of 2 256) returned within 7 days, while the highest proportion of returns was observed within 31-182 days (25.44%, 574/2 256). A higher return rate was observed among male donors (20.17%, 2 039/1 0111) compared to female donors (14.81%, 217/1 465). The return rate for repeat donors (43.02%, 2 255/5 242) was significantly higher than that of first-time donors (0.02%, 1/6 334). Individual donors showed a higher return rate (20.95%, 1 986/9 479) than group donors (12.88%, 270/2 097), with all differences being statistically significant (P<0.05). The differences in return rates across age groups were not statistically significant (P>0.05). Adverse reactions: The incidence of adverse reactions after return was 0.09% (2/2 256), significantly lower than the overall adverse reaction incidence during the same period (0.20%, 5 981/2 938 999). Both adverse reactions were local reaction (category A1, pain or bruising at the puncture site), with no reported cases of systemic vasovagal reactions (VR) or severe adverse events. Conclusion: The current blood pressure screening criteria may lead to the unnecessary deferral of eligible donors. The risk of adverse reactions is extremely low among returned donors who were deferred for abnormal blood pressure. A relaxation of the blood pressure screening criteria is therefore suggested, coupled with the optimization of donation site environment and blood pressure measurement procedure with reference to expert consensus to enhance donor retention and blood supply safety.

Thyroid hormone(TH)is an iodinated derivative of the amino acid tyrosine secreted by the thyroid gland.It promotes glycolipid metabolism and is involved in various physiological and pathological processes by regulating cellular behaviors, such as cell proliferation, differentiation, and apoptosis. Recent studies have found that aberrant expression of TH in the orbit, retina, and sclera, and other ocular tissues can induce abnormal differentiation of orbital soft tissue adipocytes, alteration of retinal oxidative stress, and degradation of posterior scleral extracellular matrix(ECM), which contributes to the pathogenesis of many ophthalmic diseases, including Graves ophthalmopathy(GO), age-related macular degeneration(ARMD), diabetic retinopathy(DR), and myopia. This article reviews the role and mechanism of TH in various ophthalmic diseases, aiming to provide theoretical basis for the prevention and treatment of these ocular disorders.

Background:
Despite advancements in laboratory animal facility management, pinworm infections remain a persistent issue in immunodeficient mouse colonies. Rapid diagnosis and treatment are crucial to mitigating potential scientific and economic consequences. Effective control requires both the administration of anthelmintic agents and rigorous environmental decontamination. However, the safety and efficacy of these treatments in genetically modified mouse models remains uncertain.Case presentation Aspiculuris tetraptera infestation was identified in multiple immunodeficient mouse models housed in a laboratory facility. Diagnosis was confirmed through fecal flotation for egg detection and necropsy for adult worm examination in the large intestines. Mice received three subcutaneous ivermectin injections at two-week intervals, coupled with environmental decontamination using ivermectin spray for four consecutive weeks. Following treatment, all colonies tested negative for A. tetraptera without any mortality.
Conclusions
A combination of subcutaneous ivermectin injection and environmental spray application effectively eradicated A. tetraptera infestation in immunodeficient mouse colonies. The treatment protocol led to the complete elimination of eggs and adult worms, offering a practical strategy for managing pinworm infections in genetically modified mouse models. Limitations include the small sample size, and the lack of a comprehensive evaluation of physiological and metabolic safety in immunodeficient mice. Further validation will be required to confirm the broader applicability of this approach.

Objective:
To analyze the intervention effects of moderate to vigorous classroom physical exercise on psychological sub health among Uyghur junior high school students, providing reference for mental health promotion and intervention in the ethnic group.
Methods:
From April to July 2022, 647 eighth grade Uighur junior high school students from two middle schools in the Kashgar Prefecture, Xinjiang, were selected using a random cluster digital sampling method. They were randomly assigned to a control group ( n =326) and an intervention group ( n =321). While adhering to the regular curriculum, the intervention group additionally received 12 week, 36 session (every Monday, Wednesday, and Friday afternoon) moderate to vigorous classroom physical exercise intervention (45 minutes per session, including warm up, main exercises, and cool down activities). Self administered psychological sub health was completed through Brief Instrument on Psychological Health of Youths before and after intervention, and the data were analyzed using covariance analysis.
Results:
Before intervention, there were no statistically significant differences between the control and intervention groups in the total scores for psychological sub health or in the scores for the three dimensions including emotional problems, conduct problems, and social adaptation difficulties ( t =0.76, 0.40, 0.01, 0.94 , all P >0.05). After intervention, the scores of the intervention group s junior high school students on the emotional problems, conduct problems, and social adaptation difficulties dimensions decreased by 0.50, 0.28, and 0.18, respectively, compared with the control group, and all differences were statistically significant ( t =3.35, 3.36, 2.07, all P <0.05). The main effect of the psychological sub health category was statistically significant ( F =60.66, P <0.01, partial η 2=0.09). Compared with the control group, the psychological sub health scores of junior high school students in the intervention group decreased by 0.96 ( t =3.42, P < 0.05 ).
Conclusion
The 12 week moderate to vigorous classroom physical exercise intervention has a positive effect on the psychological sub health of Uyghur junior high school students.

OBJECTIVE To compare the clinical efficacy and safety of Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) and Budesonide/glycopyrronium/formoterol (BUD/GLY/FOR) in the treatment of stable asthma-chronic obstructive pulmoary disease (COPD) overlap syndrome (ACOS).METHODS A retrospective analysis was performed on clinical data of 157 patients with stable ACOS who received standardized treatment at the Affiliated Hospital of Xuzhou Medical University from March 2023 to March 2025. Patients were assigned to the FF/UMEC/VI group ( n= 80, receiving FF/UMEC/VI in addition to baseline therapy) and the BUD/GLY/FOR group ( n= 77, receiving BUD/GLY/FOR in addition to baseline therapy) according to the treatment regimens. The lung function parameters [forced expiratory volume in one second (FEV 1 ), forced vital capacity (FVC), FEV 1 /FVC, FEV 1 percentage of predicted value (FEV 1 %pred), peak expiratory flow (PEF)], inflammatory markers [peripheral blood eosinophils (EOS) count, fractional exhaled nitric oxide (FeNO) level, serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α)], and clinical symptom assessment indicators [Asthma Control Test (ACT) scores, COPD Assessment Test (CAT) scores, modified Medical Research Council Dyspnea Scale (mMRC) grades] were compared between the two groups at baseline, week 12 and week 24. The occurrences of acute exacerbations and adverse reactions during the 24-week treatment were documented.RESULTS At baseline, there were no statistically significant differences in lung function parameters, inflammatory markers, or clinical symptom assessment indicators between the two groups ( P >0.05). At weeks 12 and 24, all the above indicators in both groups were significantly improved compared with pre-treatment values in the same group ( P <0.05). The FF/UMEC/VI group showed significantly greater improvements in FEV 1 , FEV 1 %pred and PEF at week 24, as well as IL-6 and TNF-α levels, ACT and CAT scores, and mMRC grades at both weeks 12 and 24, than the BUD/GLY/FOR group at the corresponding time points ( P <0.05). Within the 24-week treatment, the incidence and frequency of acute exacerbations in the FF/UMEC/VI group were significantly lower than those in the BUD/GLY/FOR group ( P <0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups ( P >0.05).CONCLUSIONS Both FF/UMEC/VI and BUD/GLY/FOR can effectively improve lung function, reduce inflammation, and alleviate symptoms in patients with ACOS, and both demonstrate good safety profiles; FF/UMEC/VI shows more pronounced advantages in improving long-term lung function, reducing levels of systemic inflammatory markers, and preventing and controlling acute exacerbations, making it more suitable for the long-term management of patients with ACOS in the stable phase.

Cholestatic liver disease (CLD) is closely associated with bile acid homeostasis imbalance, oxidative stress, inflammatory responses, mitochondrial damage, and hepatic fibrosis. Nuclear factor-erythroid 2-related factor 2 (Nrf2) can regulate molecules related to antioxidation, detoxification, and bile acid transport, and together with signaling pathways such as farnesoid X receptor (FXR), silent information regulator 1/AMP-activated protein kinase, and nuclear factor-κB, participates in the development and progression of CLD. This review summarizes the role of Nrf2 in the development and progression of CLD, as well as the research progress on traditional Chinese medicine (TCM) active constituents and formulas/Chinese patent medicine in regulating Nrf2 for the intervention of CLD. The results indicate that TCM active constituents such as terpenoids, saponins, flavonoids, and polysaccharides, as well as formulas/Chinese patent medicine with the effects of heat-clearing and dampness-draining, liver-soothing and choleretic-promoting, and body-strengthening and liver-protecting, can improve bile acid metabolism and transport and alleviate oxidative stress, inflammatory responses, and hepatic fibrosis by regulating Nrf2-related signaling pathways. However, existing studies still primarily judge based on Nrf2 expression, nuclear translocation, and downstream molecular expression changes, and the understanding of the regulatory relationship between Nrf2 and signaling pathways such as FXR, as well as the synergistic mechanisms of multiple constituents in formulas, remains insufficient. Future studies can strengthen gene intervention and functional validation, utilize liver or bile duct organoids, co-culture systems, and other approaches, and combine bile acid profiling and multi-omics analysis to further elucidate the mechanism by which TCM regulates Nrf2 to ameliorate CLD.

To investigate the epidemiological characteristics of venous thromboembolism (VTE) among inpatients at the People's Hospital of Xizang Autonomous Region, and to provide data support for the establishment of a standardized risk screening and pharmaceutical care system in the plateau chronic disease pharmaceutical clinic. This study was a retrospective cross-sectional survey. Patients discharged with a diagnosis of VTE from the People's Hospital of Xizang Autonomous Region between January 2019 and December 2024 were selected. General data, clinical outcomes, and anticoagulation regimens were collected. The Mann-Kendall trend test was used to analyze the temporal trend of VTE prevalence, and multivariate Logistic regression was used to analyze the influencing factors of VTE occurrence. A total of 939 VTE patients were included, comprising 492 females (52.40%) and 447 males (47.60%), with a mean age of (54.87±20.10) years. There were 339 elderly patients aged ≥65 years and 600 patients aged < 65 years. In terms of treatment outcomes, the clinical improvement (improvement) rate was 79.02%, and the cure rate was 10.76%. Among thrombus types, pulmonary embolism (PE) accounted for the highest proportion (58.79%), with low-risk PE being the main subtype (35.50%). The main comorbidity among VTE patients was hypertension (39.94%), followed by acute myocardial infarction or ischemic stroke (11.40%). The prevalence of VTE increased from 0.62% in 2019 to 1.07% in 2024. The Mann-Kendall trend test showed a Kendall's Tau coefficient of 0.733 ( The prevalence of VTE at the People's Hospital of Xizang Autonomous Region is on the rise. The key risk population consists of chronic disease patients with hypertension and obesity. It is necessary to further strengthen early identification of VTE, management of comorbidities, and medication monitoring for chronic disease patients, so as to improve the comprehensive management of VTE in plateau areas.

Objective:To prepare decellularized extracellular matrix (dECM)-gelatin methacryloyl (GelMA) composite hydrogels and to study their effects on hepatocyte proliferation.Methods:Hepatic dECM was prepared by elution, and GelMA hydrogel and 10%, 30% and 50% dECM-GelMA composite hydrogels were prepared by pepsin solubilization. The morphology of normal liver and dECM liver was observed by eyes and scanning electron microscopy using hematoxylin-eosin, Sirius red and periodate-Schiff staining, respectively. The internal structure of the dECM-GelMA composite hydrogels was observed by scanning electron microscopy, and the pore diameter was measured. Liver HL-7702 cells were co-cultured with GelMA hydrogel and 10%, 30% and 50% dECM-GelMA composite hydrogels, and the cell proliferation viability was determined by cell counting kit-8. The expression of proliferating cell nuclear antigen (PCNA), Wnt family protein 5a (Wnt5a), β-catenin, extracellular-regulated protein kinase 1/2 (ERK1/2) and phosphorylated ERK1/2 (p-ERK1/2) were detected by Western blotting. Comparisons were made using independent sample t-test or one-factor analysis of variance. Results:After decellularization, the hepatocyte morphology showed rounded depressions, and the extracellular matrix structure was intact. The GelMA hydrogel and 10%, 30% and 50% dECM-GelMA composite hydrogels showed inernally porous structures. The pore diameter increased from (3.06±1.35) μm in the GelMA hydrogel to (16.01±4.02) μm in the 50% dECM-GelMA composite hydrogel. On the 3rd, 5th and 7th day, the relative cell proliferation was higher in the 50% dECM-GelMA composite hydrogel group than that in the GelMA hydrogel group (1.89±0.04 vs 1.53±0.01, 9.36±0.04 vs 3.89±0.09, 7.15±0.27 vs 4.89±0.15, all P<0.05). The relative expression levels of PCNA, Wnt5a, β-catenin, and p-ERK1/2/ERK1/2 proteins in the 50% dECM-GelMA composite hydrogel group were higher than those in the GelMA hydrogel group (2.14±0.04 vs 1.00±0.03, 2.36±0.09 vs 1.00±0.08, 1.45±0.03 vs 1.00±0.04, 1.43±0.04 vs 1.00±0.01, all P<0.05). Conclusions:A dECM-GelMA composite hydrogel can be prepared, which may promote hepatocyte proliferation by upregulating the phosphorylation of ERK1/2 and activating Wnt/β-catenin signaling pathway.

Objective To explore the status of nursing work engagement, nursing work environment and emotional intelligence and their relationship among nurses who work in hematopoietic stem cell transplantation (HSCT) units. Methods A total of 225 HSCT nurses were selected as study subjects by convenience sampling method. Utrecht Work Engagement Scale, Nursing Work Environment Scale and Emotional Intelligence Scale were used to assess the work engagement, work environment and emotional intelligence among these nurses. AMOS 23.0 software was used to construct the structural equation model. Results The median and 25th and 75th percentiles of the score of work engagement of the research subjects were 59.0 (54.0, 64.0) points. The average scores of the nursing work environment and emotional intelligence were (117.8±21.5) and (58.8±10.7) points, respectively. The score of work engagement was positively correlated with the scores of the nursing work environment and emotional intelligence (rank correlation coefficients were 0.550 and 0.431, respectively, both P<0.01). The total score of the nursing work environment was positively correlated with the total score of emotional intelligence (correlation coefficient was 0.271, P<0.01). The nursing work environment influenced the work engagement status of HSCT nurses through the mediating effect of emotional intelligence, with an indirect effect of 0.115 (95% confidence interval: 0.201-0.365), accounting for 20.4% of the total effect. Conclusion Emotional intelligence is a mediating variable between the nursing work environment and work engagement of HSCT nurses.
