Objective:To develop the Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy and evaluate its reliability and validity.Methods:Based on the theory of unpleasant symptoms, a preliminary version of the Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy was developed through literature analysis, semi-structured interviews, and the Delphi method. After revising certain items in the pre-survey, convenience sampling was used to select patients who underwent bladder instillation chemotherapy in the Department of Urology Surgery of three ClassⅢ Grade A hospitals in Yunnan Province from January to July 2024 as research subjects to test the reliability and validity of the scale.Results:A total of 168 questionnaires were distributed, and 162 valid questionnaires were collected, with a valid response rate of 96.429% (162/168). The Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy covered two areas of symptom severity and symptom distress, comprising five dimensions and 27 items. The Cronbach's α coefficient for the total scale was 0.953, and the split-half reliability coefficient was 0.806. Exploratory factor analysis revealed that the four common factors for symptom severity contributed to 73.196% of the cumulative variance, while the single common factor for symptom distress accounted for 68.285% of the cumulative variance. Confirmatory factor analysis revealed that all indicators met the fit criteria, indicating that the model possessed good goodness-of-fit. The content validity index at the scale level was 0.940, while the content validity index at the item level ranged from 0.833 to 1.000.Conclusions:The Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy developed in this study demonstrates good reliability and validity, and is suitable for evaluating symptoms in patients undergoing bladder infusion chemotherapy.

Jiaxing city is one of the pilot cities for the Long-term Care Insurance(LTCI)policy in Zhejiang Province.This study examines the current implementation status of Jiaxing's LTCI policy in terms of financing(including financing targets,channels,methods,and standards)and benefit payments(including payment forms,contents,standards,and levels).It summarizes the experiences and challenges encountered during the pilot process.Currently,Jiaxing's LTCI policy has undergone continuous improvement in financing and benefit payment mechanisms.The financing targets now cover both urban and rural residents,and the coverage has expanded from individuals with severe disabilities to include those with severe dementia.The benefit content has been refined,with the introduction of a detailed service project directory and service pricing.For the future,it is recommended to expand the coverage to individuals with moderate disabilities,based on the fund's capacity and sustainability,and to differentiate benefit standards according to the severity of disability.Furthermore,it is suggested to strengthen the responsibilities of employers and individuals,diversify financing channels,and gradually explore an independent financing mechanism for LTCI.A combination of fixed-amount and proportional financing methods should be considered,alongside factors such as intergenerational equity and population aging trends,to establish a scientific and dynamic premium adjustment mechanism.

Objective To elucidate the underlying mechanisms of sperm-associated antigen 6(SPAG6)in the proliferation and drug resistance of B-cell acute lymphoblastic leukemia(B-ALL).Methods A total of 56 B-ALL patients and 15 iron-deficiency anemia(IDA)patients admitted in the First Affiliated Hospital of Chongqing Medical University from January 2019 to December 2023 were recruited and served as the experimental and control groups,respectively.Bone marrow mononuclear cells(BMMNCs)were derived from the bone marrow tissues of the experimental group.According to the results of qRT-PCR for the expression of SPAG6 in the obtained BMMNCs,the B-ALL patients were stratified into newly-diagnosed(New-diag)group,complete remission(CR)group,minimal residual disease Possitive(MRD+)group,and relapse group.Lentiviral vectors were used to construct B-ALL cells with SPAG6 overexpression and knockdown.CCK-8 assay and methylcellulose-based colony formation experiment were employed to assess the survival,proliferation,and clonogenic potential of the cells with varying SPAG6 expression levels.After f B-ALL cells were treated with the chemotherapeutic drugs,daunorubicin(DNR)and methotrexate(MTX),CCK-8 assay,flow cytometry and Western blot analysis were applied to detect cell viability(drug sensitivity andIC50),cell apoptosis,and protein levels of apoptosis-related molecules Bax,Caspase-3 and Bcl-2,respectively.The mRNA-seq profiles of B-ALL patients were obtained from the TARGET database,and gene set enrichment analysis(GSEA)was conducted to explore SPAG6-associated signaling pathways,which were subsequently validated experimentally.After treatment with the NF-κB agonist Phorbol 12-myristate 13-acetate(PMA)and the antagonist BAY-11-7082,cell viability and sensitivity to chemotherapeutic drugs were assessed with CCK-8 assay,and the expression of pathway-related proteins NF-κB P65,p-NF-κB p65,IK Bα,p-IKBα,TNF-α,and EPO was detected by Western blot analysis.A mouse xenograft tumor model was constructed in SPAG6-/+knockdown mice to observe the effect of DNR on tumor growth and the expression of the NF-κB signaling pathway in the tumor tissues with immunohistochemical assay.Results The mRNA level of SPA G6 was significantly higher in the B-ALL patients(P＜0.05),and in the MRD group(P=0.001)and R group(P=0.003)than the CR group.SPAG6 overexpression and knockdown in B-ALL cells confirmed that SPAG6 promoted the proliferation(P＜0.05)and decreased the sensitivity to DNR and MTX(P＜0.05).SPAG6 resisted chemotherapy-induced apoptosis in B-ALL cells by down-regulating pro-apoptotic proteins Bax and Caspase-3(P＜0.05),and up-regulating the expression of anti-apoptotic protein Bcl-2(P＜0.05).GSEA analysis suggested that the NF-κB pathway was enriched in B-ALL cells,and our experiments confirmed that SPAG6 enhanced the chemoresistance of B-ALL cells to chemotherapy by activating the NF-κB/TNF-α pathway.In in vivo experiments,knocking SPAG6 down significantly reduced the volume of transplanted tumors(P＜0.05),and an additional decrease in tumor growth was observed in the DNR-combined treatment group(P＜0.05),with reduced levels of NF-κB P65 and p-IKBα by immunohistochemical assay.Conclusion SPAG6 promotes the proliferation of B-ALL cells and reduces their chemosensitivity via the NF-κB/TNF-α pathway,suggesting a close association of SPAG6 with the therapeutic outcomes and prognosis in B-ALL patients.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To study the inhibitory effect of attenuated salmonella SGN1, overexpressing methioninase, on nasopharyngeal carcinoma (NPC) and the underlying mechanism. Methods The cell proliferation, cell cycle, cell apoptosis, clony formation and migration a-bility of 5-8F, HNE-2, CNE-2 cells were measured u-sing flow cytometry assay, clone formation assay, and wound assay after the methionine restriction treatment. 5-8F, HNE-2, CNE-2 cells were infected with SGN1 at the multiplicity of infection (MOI) of 1: 100 for 5 hours, followed with the measurement of cell growth. A xenograft model was constructed by subcutaneous injection of 5-8F cells in mice to observe the inhibitory effect of SGN1 on nasopharyngeal carcinoma. Results Compared with the control group, methionine restriction significantly inhibited the proliferation, migration ability, and clone formation of nasopharyngeal carcinoma cells and blocked the G

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

OBJECTIVE: To investigate the association of isolated thyroid peroxidase antibody (TPOAb) positive in the first trimester with fetal growth. METHODS: A total of 16 446 pregnant women were included in the birth cohort study, whose last menstrual period was between May 2016 and April 2019 and with singleton pregnancy. Maternal serum samples were collected when they firstly came for prenatal care in the first trimester. The pregnant women were consecutively seen and followed in the hospital and the information of pregnant women was extracted from the electronic medical information system. The pregnant women were divided into isolated TPOAb positive group (n=1 654) and euthyroid group (n=14 792). Three fetal ultrasound examinations were scheduled during the routine prenatal visits at the hospital and were performed by trained sonographers. All fetal growth indicators were quantified as gestational age- and gender- adjusted standard deviation score (Z-score) using the generalized additive models for location, scale and shape (GAMLSS). Fetal growth indicators included estimated fetal weight (EFW), abdominal circumference (AC), biparietal diameter (BPD), femur length (FL) and head circumference (HC). Fetal growth restriction (FGR) was defined as AC or EFW Z-score＜3rd centile based on clinical consensus. Generalized estimating equation (GEE) analysis was applied to assess the association of maternal isolated TPOAb positive with fetal growth. The generalized linear model was further used to analyze the association between isolated TPOAb positive and fetal growth indicator at different gestational ages when the fetal growth indicator was significantly associated with isolated TPOAb positive in the GEE mo-del. RESULTS: The median gestational age at three ultrasound measurements was 23.6 (23.3, 24.1), 30.3 (29.7, 30.9), 37.3 (37.0, 37.7) weeks, respectively. The BPD Z-score was higher in isolated TPOAb positive women, compared with the euthyroid pregnant women after adjustment (β=0.057, 95%CI: 0.014-0.100, P=0.009). The generalized linear model showed the BPD Z-score was higher in the isolated TPOAb positive women at the end of 21-25 weeks (β=0.052, 95%CI: 0.001-0.103, P=0.044), 29-32 weeks (β=0.055, 95%CI: 0.004-0.107, P=0.035) and 36-40 weeks (β=0.068, 95%CI: 0.011-0.125, P=0.020), compared with the euthyroid pregnant women. There was no difference in other fetal growth indicators (EFW, AC, FL and HC) and FGR between the isolated TPOAb positive and euthyroid pregnant women. CONCLUSION The BPD Z-score was slightly increased in the isolated TPOAb positive pregnant women in the first trimester, while other fetal growth indicators were not changed. The reproducibility and practical significance of this result need to be confirmed.
