Objective: To examine the associations between 24 hour movement behavior allocation patterns and physical fitness as well as serum high sensitivity C-reactive protein (hsCRP) levels among female college students, providing evidence for developing personalized health promotion strategies. Methods: In September 2025, 48 female college students aged 18-22 years were recruited from a comprehensive university from Shanghai. Continuous 24 hour movement behaviors were monitored using a triaxial accelerometer (ActiGraph GT3X+). Serum hsCRP levels were measured (≥1 000 ng/mL was log grade inflammation), and physical fitness indicators including upper limb muscle strength, vital capacity, and maximal oxygen consumption (VO 2max ) were assessed. Spearman rank correlation analysis was used to evaluate the correlation between variables. Compositional data analysis combined with multiple linear regression was employed to construct isotemporal substitution models, evaluating the effects of substituting 30 minutes of one behavior for another on hsCRP and VO 2max . Results: Female college students had the longest average daily sedentary behavior (SB) time (643.2±103.2)min, which was higher than sleep time (452.4±90.0)min, light physical activity (LPA) time (279.0±76.8)min and moderate to vigorous physical activity (MVPA) time (66.0±21.6)min. Correlation analysis revealed that vigorous physical activity (VPA) was positively correlated with hsCRP levels among female college students ( r=0.47, P <0.05). Substituting 30 minutes of MVPA with sleep, SB or LPA significantly reduced predicted hsCRP levels among female college students ( β = -0.90, -0.90, -0.73), replacing 30 minutes of sleep with MVPA significantly increased predicted VO 2max levels ( β =5.12) (all P <0.05). The low grade inflammation group exhibited longer durations of high intensity activity participation and higher mean values for height, body weight, and grip strength compared to the normal group ( t =2.17, 2.52, 2.21, all P <0.05). Within the normal inflammation group, MVPA was positively associated with VO 2max ( β =0.18), while sleep was negatively associated ( β =-0.07) (both P <0.05). In contrast, no statistically significant associations were observed between any activity behavior and VO 2max in the low grade inflammation group (all P >0.05). Conclusions MVPA exerts bidirectional effects on the health of female college students. While it enhances cardiorespiratory fitness, it may concurrently elevate chronic low grade inflammation levels. To maximize health benefits, intervention programs focused on increasing MVPA should also give full consideration to the importance of restorative sleep.

Objective To report cases of checkpoint inhibitor pneumonitis （CIP） in patients with advanced biliary tract cancer, aiming to provide additional approaches for the assessment, treatment, and monitoring of this condition. Methods Three patients developed oxygen desaturation and interstitial lung lesions during chemotherapy combined with immunotherapy, and were diagnosed with CIP in collaboration with the respiratory department. Antitumor therapy was discontinued in the acute phase, and glucocorticoids were administered, with regular monitoring of disease progression. During follow-up, case 1 developed lung metastasis; case 2 showed improvement; case 3 had concurrent infection and tumor progression. Results Glucocorticoids improved lung lesions and hypoxic symptoms in patients with CIP, but attention should be paid to the potential for concurrent infections and tumor progression. Conclusions Comprehensive assessment and early identification of CIP are crucial for patients with advanced biliary tract cancer. For those with recurrent symptoms after glucocorticoid therapy, timely and accurate adjustment of the treatment regimen is essential.

Objective:To explore the clinical characteristics, treatment, and prognosis of patients with spondyloarthritis (SpA) and clinically insignificant monoclonal garmmopathy of undetermined significance (MGUS).Methods:A retrospective study was performed to analyze the clinical characteristics of patients simultaneously diagnosed with both SpA and MGUS at the First Affiliated Hospital to Zhengzhou University between January 2020 and December 2024, supplemented by a literature review.Results:Among the 5 patients (2 males, 3 females; age range 33~65 years), 4 presented with peripheral arthritis and 2 with extra-articular manifestations. All patients demonstrated elevated globulin and IgG levels, with 4 being HLA-B27 positive. M-protein typing revealed IgG/κ in 3 cases and IgA/λ in 2. All five patients underwent both X-ray and MRI examinations, with sacroiliitis being detected in 4 cases. Three patients with long disease duration showed poor response to conventional therapy (NSAIDs/DMARDs). Targeted therapies yielded variable outcomes: one patient achieved normalized globulin/IgG levels with etanercept (3-year follow-up without MGUS progression); another showed marked clinical improvement and significant globulin/IgG reduction with JAK inhibitor (tofacitinib, treated for 7 years); while a third demonstrated no symptom relief then switching from TNF-α inhibitor to IL-17 inhibitor.Conclusion:Persistent hyperglobulinemia in SpA patients warrants MGUS screening. Those with SpA-MGUS may require targeted therapies, where JAK inhibitors and monoclonal TNF-α inhibitors appear to be the preferred options, though long-term monitoring for MGUS progression remains essential.

Objective:To analyze the situation of rodents carrying Hantavirus and the genetic and evolutionary characteristics of the virus in Zibo city, Shandong province in 2022, and provide reference for the scientific prevention and control of hemorrhagic fever with renal syndrome (HFRS).Methods:Real-time quantitative PCR (RT-qPCR) was used to detect hantavirus (HV) nucleic acids in rodent lung tissues and identify HV genotypes. Each nucleic acid fragment was designed to amplify various gene fragments by segment, and the whole genome of Hantavirus was sequenced by second generation sequencing. Sequence assembly was performed using SeqMan 7.1.0.44, a subprogram of DNAStar. Sequence alignment and evolutionary analysis were conducted using MEGA 7.0 and BioEdit software.Results:A total of 270 host animals were captured in this survey. Among them, 13 rodent lung samples tested positive for Hantavirus, resulting in a virus-positive rate of 4.8%. The full-genome sequences of four hantavirus strains were successfully obtained, all identified as Seoul virus (SEOV) genotype. Four Hantavirus-positive samples showed high nucleotide sequence homology in the M gene and belonged to the SEOV S3 subtype. These strains exhibited high similarity with those from Hebei, Liaoning, and Beijing. The amino acid sequences of the nucleoprotein and glycoprotein immunogenic epitopes were identical to those of the vaccine strain Z37.Conclusions:This study successfully determined the full genome sequences of four hantavirus strains from Zibo city, Shandong province. The genotypes are primarily SEOV, with the subtype being S3. The homology of genes within the same subtype is high, with no significant variations observed. The alignment of immune epitopes in key proteins suggests that the current vaccine may provide protection against locally circulating strains, but further in-depth research is still required.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.

Objective: To investigate the current status of iron metabolism among apheresis donors in Guangzhou and analyze the improvement effects of health education on iron deficiency in frequent apheresis donors. Methods: Using a generalized linear mixed model (GLMM), a 180-day follow-up was conducted on 261 eligible apheresis donors at the Guangzhou Blood Center from January to July 2024. Hemoglobin (Hb), serum ferritin (SF), unsaturated iron-binding capacity (UIBC), total iron-binding capacity (TIBC), and transferrin saturation (TS) were selected as outcome variables. The effects of gender, age group, and number of donations within 180 days on these outcomes were analyzed and modeled. A general linear model (GLM) with repeated measures was applied to 55 donors who received health education interventions, comparing changes in Hb and iron metabolism-related indicators before and after follow-up and health education. Results: No significant difference in Hb levels was observed between first-time and regular apheresis donors, but SF levels were significantly higher in first-time donors (F=6.195, P<0.05). The GLMM revealed that female donors exhibited more significant reductions in Hb (T=-12.546) and SF (T=-5.829)(P<0.05 for both). Age group showed no interactive effects on Hb or SF changes. While number of donations within 180 days had no interactive effect on Hb, SF levels significantly decreased with increased number of donations (using ≥9 donations as the reference group; P<0.05 for all groups). After health education, Hb levels remained unchanged, but SF increased compared to pre-intervention levels (mean difference: -18.571, P<0.05), though a declining trend persisted compared to baseline (mean difference from baseline to post-intervention: 23.068,P<0.05). Conclusion: Female and number of donations are primary factors contributing to SF reduction in apheresis donors. Health education interventions promote SF recovery. Extending donation intervals and reinforcing iron deficiency-related health education may improve iron status in donors.

A 66-year-old female patient self-administered Jingyaokang capsules (a compound preparation of traditional Chinese medicines, 3 capsules thrice daily orally) due to lumbar pain. The patient developed oliguria and edema of bilateral lower limbs after 3 doses of medication on the same day. The laboratory tests showed WBC 7.3×10 9/L, neutrophil percentage 0.70, blood urea 12.7 mmol/L, blood crea- tinine 179 μmol/L, and blood uric acid 461 μmol/L. The kidney function tests 15 days ago showed no abnormalities in the patient. Acute kidney injury caused by Jingyaokang capsules was considered. The drug was stopped and symptomatic treatments including torasemide and maintenance of fluid balance were given. The patient′s urine output gradually increased. Five days later, the patient′s edema of bilateral lower limbs disappeared, and her blood urea and creatinine decreased to normal range. The acute kidney injury in the patient may be related to strychni semen component in the Jingyaokang capsules.

Objective To explore the evidence for Traditional Chinese Medicine(TCM)in the treatment of premature ovarian insufficiency(POI)based on evidence map and re-evaluation of systematic reviews.Methods CNKI,WanFang Data,VIP,SinoMed,PubMed,Embase,Cochrane Library and Web of Science database were electronically searched to collect systematic reviews(SR)/Meta-analysis on the treatment of POI with TCM from the inception to March 31,2025.The reporting quality,methodological quality,and evidence quality of the included studies were evaluated using the PRISMA 2020 Statement,AMSTAR 2 Checklist,and GRADE system,respectively.The interventions,number of studies,and evidence grades were comprehensively displayed using evidence map.Results A total of 15 SR/Meta-analysis were included,comprising 9 Chinese articles and 6 English articles.The PRISMA 2020 checklist evaluation revealed that 8 articles had certain deficiencies in reporting,while 7 articles demonstrated relatively complete reporting.Based on the AMSTAR 2 checklist,5 articles were rated as high-level and 10 as very low-level.A total of 10 primary outcome indicators were involved,reported 133 times.When classified using the GRADE system,there were 20 pieces of moderate-quality evidence,58 pieces of low-quality evidence,and 55 pieces of very low-quality evidence.The evidence map showed that TCM alone or in combination with hormone therapy could effectively treat POI,reduce follicle-stimulating hormone and luteinizing hormone levels,increase estradiol levels,and improve clinical manifestations and TCM syndrome manifestations.Conclusion TCM has certain advantages in the treatment of POI,enhancing the overall treatment effect,alleviating clinical symptoms of low estrogen,and regulating sex hormone levels to some extent.However,there are deficiencies in methodological quality and reporting quality,and the level of evidence is not high.Therefore,the findings should be used with caution in clinical practice.

Objective To identify determinants of subtherapeutic voriconazole(VRCZ)concentrations in allogeneic hematopoietic stem cell transplantation(allo-HSCT)recipients and to develop/validate a nomogram-based risk prediction model.Methods This study retrospectively analyzed 310 VRCZ therapeutic drug monitoring(TDM)measurements from allo-HSCT recipients at 310 patients who under went allo-HSCT surgery at Hebei Yanda Ludaopei Hospital from October 2022 to October 2024 and received VRCZ for the prevention and treatment of invasive fungal infections before transplantion were selected as the study subjects.Cases were stratified into target-concentration group(0.5～5.0μg/ml)and subtherapeutic group(<0.5μg/ml).Through single factor and multiple factor Logistic regression analysis,indeipendent predictive factors forvecz plasma concentration non-compliance were screened,and a column chart prediction model(NPM)was constructed.The performance of the model was evaluateding area under the receiver operating characteristic curve(AUC),Hosmer-Lemeshow(H-L)goodness-of-fit test,and decision curve analysis(DCA).Results Among 310 VRCZ-TDM measurements,71.61%(222/310)achieved target concentrations.Multivariate analysis showed that CYP2C19 intermediate metabolite,daily dose of cyclosporine A(CSA),daily dose of VRCZ,creatinine(Cr)>97 μmol/L,albumin(Alb)and C-reactive protein(CRP)were independent influencing factors for VRCZ blood drug concentration non-compliance(Wald χ2=4.046～13.221,all P＜0.05).The nomogram demonstrated excellent discrimination,calibration(H-L goodness of fit test χ2=2.663,P=0.954),and clinical utility with net benefit across 0.05～0.96 risk thresholds.Conclusion The nomogram incorporating CYP2C19 gene phenotype,daily CSA dosing,daily VRCZ dosing,Cr levels,Alb and CRP provides a validated tool for optimizing VRCZ therapy in allo-HSCT recipients,enabling precision dosing strategies.
