Objective To evaluate the security of inspiring high concentration oxygen by detecting the reactive oxygen species of the rats brain homogenates after inspiring high concentration oxygen for a certain time.Methods Sixty wister rats weighting 150~200g were randomly devided into five groups(the group of 4h、8h、12h、16h and the control group,12/group).The experimental rats were exposed to 85%~100% oxygen in a self-made chamber and the control animals were kept in normal room air.The Concentration of the MDA,SOD,GSH,NO,NOS,CAT and T-AOC of the brain homogenates was detected.Results Compared with the control group,the level of MDA,NO and NOS in the brain homogenates grew up markedly(P

Objective To explore the correlations of perceived social support and burnout with general well-being among caregivers in nursing homes. Methods One hundred nursing workers were selected from three nursing homes in Guangzhou. Perceived social support scale ( PSSS ) , Maslach burnout inventory ( MBI ) and general well-being schedule ( GWBS ) were used to investigate the status of their support, burnout and general well-being and analyze the correlations between them. Results The scores on perceived social support, job burnout and general well-being were (59.00 ± 9.00), (2.49 ± 0.88), (77.19 ±9 .90), respectively, all at moderate level. The scores on emotional exhaustion and depersonalization were significantly higher than the norms (both P<0.001). Job burnout together with its three dimensions was negatively correlated with general well-being (all P<0.01), while perceived social support was positively correlated with general well-being ( P < 0 . 01 ) . The exogenous family support , emotional exhaustion and personal accomplishment influenced caregiver′s general well-being (all P<0.01). Conclusions Perceived social support, job burnout and general well-being are all at moderate level in caregivers of nursing homes. The higher the perceived social support, the lower the job burnout, the higher the passion and the general well-being in care workers. The general well-being of caregivers of the nursing homes was not high. The managers should pay more attention to them and measures should be taken to promote their physical and mental health.

Objective: To conduct a scoping review on the types, construction methods and predictive performance of health literacy prediction models based on machine learning methods, so as to provide the reference for the improvement and application of such models. Methods: Publications on health literacy prediction models conducted using machine learning methods were retrieved from CNKI, Wanfang Data, VIP, PubMed and Web of Science from inception to May 1, 2024. The quality of literature was assessed using the Prediction Model Risk of Bias ASsessment Tool. Basic characteristics, modeling methods, data sources, missing value handling, predictors and predictive performance were reviewed. Results: A total of 524 publications were retrieved, and 22 publications between 2007 and 2024 were finally enrolled. Totally 48 health literacy prediction models were involved, and 25 had a high risk of bias (52.08%), with major issues focusing on missing value handling, predictor selection and model evaluation methods. Modeling methods included regression models, tree-based machine learning methods, support vector machines and neural network models. Predictors primarily encompassed factors at four aspects: individual, interpersonal, organizational and society/policy aspects, with age, educational level, economic status, health status and internet use appearing frequently. Internal validation was conducted in 14 publications, and external validation was conducted in 4 publications. Forty-two models reported the areas under the receiver operating characteristic curve, which ranged from 0.52 to 0.983, indicating good discrimination. Conclusion Health literacy prediction models based on machine learning methods perform well, but have deficiencies in risk of bias, data processing and validation.

Objective To explore the impact of macrophage-to-myofibroblast transition(MMT)on pulmonary fibro-sis induced by acute lung injury by LPS.Methods Totally 21 male mice were randomly classified into 7 groups:control group,model group(LPS-PF)at different time points and intervention group of clodronate-liposomes(CL-LIP)treatement at different time points(n=3).Pulmonary fibrosis was identified by HE and Masson staining microscopy.The immuno-fluorescence technology was used for the evaluation of numbers of macrophage-to-myofi-broblast transition cells(MMT cell which co-expressed CD68 and α-SMA).Bone marrow-derived macrophages(BMDMs)were randomly classified into two group:control(Ctrl)group and TGF-β1-treated group induced by transforming growthfactor-β1.α-SMA,FN and Col1 were detected by RT-qPCR.The expression of α-SMA,Smad3 and p-Smad3 protein was evaluated by Western blot.Results At day 7,the Ashcroft score of lung tissue in LPS-PF mouse model was significantly increased when compared with the Ctrl group(P＜0.01);While the score signifi-cantly declined when the model was pretreated with CL-LIP(P＜0.05).As detected by immuno-fluorescence stai-ning,in CL-LIP group the number of CD68-positive cells co-labeled with α-SMA was obviously less then that of LPS-PF group of the corresponding time point(P＜0.01).When the BMDMs were stimulated by TGF-β1 at 24 h,48 h and 96 h respectively,a higher expression of α-SMA,FN,Col1,were found in TGF-β1-treated group than that in Ctrl group at the corresponding time point(P＜0.01).The expression of Smad3,p-Smad3 significantly higher in LPS-PF group(at both day 7 and day 10)and TGF-β1-treated group(at both 48 h and 96 h)as compared to cor-responding control group(P＜0.01).Conclusions MMT promotes pulmonary fibrosis induced by ALI via LPS.Smad3 is proved to be involved in the MMT process.

Objective:To investigate the microsurgical efficacy of large primary intracranial solitary fibrous tumor and influencing factors for its prognoses.Methods:From January 2010 to December 2022, 47 patients with large primary intracranial solitary fibrous tumor admitted to and accepted microsurgery in Department of Neurosurgery, Wuhan Central Hospital and Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, were enrolled. The clinical data, microsurgical efficacy and follow-up results of these patients were retrospectively analyzed, and influencing factors for total resection and prognoses were determined.Results:Thirty-two patients had tumor within the supratentorial region and 15 in the mandibular region, including 24 with sinus involved tumor. According to 2021 WHO Classification of Tumors of the Central Nervous System, 5 patients (10.6%) had grading 1, 32 (68.1%) grading 2, and 10 (21.3%) grading 3. Total resection was achieved in 31 patients (66.0%) and subtotal resection in 16 patients (34.0%). Postoperative complications, such as intraoperative hemorrhage, distant epidural hematoma and subcutaneous effusion, occurred in 7 patients (14.9%) and they were cured after secondary hematoma removal or conservative treatment; residual limb mobility disorder occurred in 3 patients, visual impairment in 3, and postoperative seizures in 2. Adjuvant radiotherapy was performed in 13 patients (27.7%). Follow-up was performed for (69.1±29.6) months and 29 patients (61.7%) had recurrent tumors (6 with intracranial and extracranial metastases and 4 deaths). Mean progression-free survival was (57.5±25.1) months; the 1-, 3-, and 5-year progression-free survival rates were 95.7%, 87.2%, and 59.6%, respectively. Sinus involvement was the independent influencing factor for total tumor resection; and total resection was an independent protective factor for progression-free survival for large primary intracranial solitary fibrous tumor ( HR=4.291, 95% CI: 1.555-11.838, P=0.005). Conclusion:Patients with large primary intracranial solitary fibrous tumor have a high recurrent risk after surgery; and gross-total resection should be strived to prevent tumor recurrence.

Objective:To access the clinical efficacy and safety of hydroxychloroquine (HCQ) in treatment of IgA nephropathy (IgAN).Methods:The data of IgAN patients who were diagnosed by renal biopsy in the First Affiliated Hospital, College of Medicine, Zhejiang University from May 2016 to August 2020 and had been treated with HCQ for more than 6 months without other immunosuppressants were retrospectively analyzed. The efficacy and side effects were compared between groups according to the baseline urine protein/creatinine ratio (UPCR) or whether combined with renin-angiotensin-aldosterone system inhibitor (RAASi).Results:A total of 121 patients were enrolled, including 45 males (37.19%). At baseline, the median UPCR was 0.69(0.45, 1.00) g/g; the median estimated glomerular filtration rate (eGFR) was 93.46(73.14, 115.67) ml·min -1·(1.73 m 2) -1; the median serum creatinine was 80.00(61.00, 98.00) μmol/L, and the serum albumin was (44.39±3.36) g/L. After HCQ treatment, UPCR and red blood cells were significantly decreased compared with baseline (all P<0.05). Triglyceride, total cholesterol and low-density lipoprotein cholesterol were also significantly decreased during the follow-up period. Serum creatinine, eGFR, serum albumin and serum uric acid remained stable. After 6 months of follow-up, the total remission rate was 56.88%, including 15.60% of partial remission and 41.28% of complete remission; at the end of follow-up, the median follow-up time was 280.00(214.00, 411.00) days and the total remission rate was 56.20%, including 9.92% of partial remission and 46.28% of complete remission. Group analysis showed that the remission rate was 60.53% ( n=76) and 48.48% ( n=33) at 6 months (Mann-Whitney U test, Z=-2.331, P=0.020) and 57.65% ( n=85) and 52.78% ( n=36) at the end of follow-up (Mann-Whitney U test, Z=-1.673, P=0.094) between patients with baseline UPCR<1 g/g and patients with baseline UPCR≥1 g/g; and the remission rate was 66.67% ( n=30) and 53.16% ( n=79) at 6 months (Mann-Whitney U test, Z=1.062, P=0.288) and 61.29% ( n=31) and 54.44% ( n=90) at the end of follow-up (Mann-Whitney U test, Z=0.930, P=0.352) between patients with single HCQ and patients with HCQ+RAASi. For side effects, the eGFR of 2 patients decreased by more than 30% compared with baseline, 1 patient relapsed and 1 patient developed blurred vision. Conclusions:HCQ is safe and effective for the treatment of IgAN.
