Sichuan Province is a hilly schistosomiasis-endemic province in China with the highest endemicity and largest coverage. During the period of more than 70 years of integrated control, there are five distinct phases of schistosomiasis control in Sichuan Province, including baseline investigation, Oncomelania hupensis snail control, chemotherapy for both humans and livestock, management of source of Schistosoma japonicum infections, and sustained control and intensified surveillance and early warning, and a package of key interventions are implemented, including environmental modification, snail control with chemical treatment, large-scale chemotherapy for humans and livestock, management of source of S. japonicum infections, intensified integrated control, establishment of an early warning and surveillance system. As a result, schistosomiasis has been eliminated across all 63 disease-endemic counties (cities, districts) in Sichuan Province by June 2025. Government-led multi-sectoral collaborations, science and technology-supported precision control strategies, and a sustainable control model tailored to the ecological and socio-economic conditions in endemic regions are essential to achieving the target of schistosomiasis elimination in Sichuan Province.

ObjectiveTo investigate the influence of entecavir （ETV） versus tenofovir alafenamide fumarate （TAF） on renal function in previously untreated patients with chronic hepatitis B （CHB）. MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023， and according to the antiviral drug used， they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data， propensity score matching （PSM） was used for matching and analysis at a ratio of 2∶1， and the two groups were compared in terms of estimated glomerular filtration rate （eGFR） and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48， the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function， and the receiver operating characteristic （ROC） curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function， and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching， there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group （all P>0.05）， with an eGFR level of 112.29±9.92 mL/min/1.73 m² in the ETV group and 114.72±12.15 mL/min/1.73 m² in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups， and compared with the TAF group at week 48， the ETV group had a significantly lower eGFR （106.42±14.12 mL/min/1.73 m² vs 112.25±13.44 mL/min/1.73 m²， t=-2.422， P=0.017） and a significantly higher incidence rate of abnormal renal function （17.00% vs 4.00%， χ²=5.092， P=0.024）. After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients， the univariate analysis showed that there were significant differences between the two groups in age （Z=-2.039， P=0.041）， treatment drug （ETV/TAF） （χ²=5.092， P=0.024）， and baseline eGFR level （t=4.023， P<0.001）， and the multivariate Logistic regression analysis showed that baseline eGFR （odds ratio ［OR］=0.896， 95% confidence interval ［CI］： 0.841 — 0.955， P<0.001） and treatment drug （OR=5.589， 95%CI： 1.136 — 27.492， P=0.034） were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients， with a cut-off value of 105.24 mL/min/1.73 m²， a sensitivity of 73.68%， and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m² had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m² （χ²=22.330， P<0.001）， and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group （χ²=4.961， P=0.026）. With the initiation of antiviral therapy， both the ETV group and the TAF group had a significant reduction in eGFR （F=5.259， P<0.001）， but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 （t=-2.422， P=0.017）； both the baseline eGFR≤105.24 mL/min/1.73 m² group and the baseline eGFR>105.24 mL/min/1.73 m² group had a significant reduction in eGFR （F=5.712， P<0.001）， and there was a significant difference in eGFR between the two groups at baseline and weeks 12， 24， 36， and 48 （t=-13.927， -9.780， -8.835， -9.489， and -8.953， all P<0.001）. ConclusionFor CHB patients initially treated with ETV or TAF， ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.

Objective To investigate the expression of NOP2/Sun RNA methyltransferase family member 2(NSUN2)and protein arginine methyltransferase 5(PRMT5)in retinoblastoma(Rb)tissue and their correlation with the survival prognosis of Rb patients.Methods From February 2019 to February 2021,84 patients with Rb(Rb group)were selected from Beijing Anzhen Hospital Affiliated to Capital Medical University Nanchong Hospital,and 50 normal retinal tissues were used as control group.Real-time fluorescence quantitative PCR(qRT-PCR)was used to detect the levels of NSUN2 mRNA and PRMT5 mRNA in retinal tissues.Kaplan-Meier curve was used to analyze the effect of NSUN2 mRNA and PRMT5 mRNA on the prognosis of Rb patients.COX regression analysis was used to analyze the factors affecting the prognosis of Rb.Results The expression of NSUN2 mRNA(3.11±0.42)and PRMT5 mRNA(2.84±0.39)in Rb cancer tissues were higher than that in the control group(0.80±0.23,0.76±0.20),and the differences were statistically significant(t=35.935,35.033,all P<0.001).The expression of NSUN2 mRNA and PRMT5 mRNA in Rb cancer tissues with tumor diameter≥20mm,undifferentiated and ⅡRC stage D～E were higher than that in tumor diameter<20mm,differentiated tissues and ⅡRC stage A～C cancer tissues,and the differences were statistically significant(t=18.297,141.770,16.693;18.663,139.144,39.947,均P<0.001).The 3-year progression-free survival rate in the high expression group of NSUN2 mRNA was lower than that in the low expression group(60.00%vs 88.64%).The 3-year progression-free survival rate in the high expression group of PRMT5 mRNA was lower than that in the low expression group(56.10%vs 93.02%)(Log rank χ2=13.440,19.501,all P<0.001).Undifferentiated type,ⅡRC stage D-E stage,NSUN2 mRNA high,PRMT5 mRNA high were risk factors affecting the prognosis of Rb patients(Waldχ2=5.923～7.161,all P<0.001).Conclusion The expression of NSUN2 mRNA and PRMT5 mRNA in Rb tissues is increased,which is related to the maximum diameter of tumor,pathological classification and ⅡRC stage,and can be used as a tumor marker to evaluate the survival prognosis of Rb.

Aim To explore the mechanism by which dioscin regulates IL-17+γδT cells in the treatment of arthritis.Methods A collagen-induced arthritis(CIA)model was established in DBA/1 mice using bovine type Ⅱ collagen.The mice were randomly divid-ed into the CIA model group,methotrexate(MTX)positive control group,and dioscin low-dose(Dioscin-L),medium-dose(Dioscin-M),and high-dose(Dios-cin-H)groups.After intervention,the therapeutic effects were evaluated using scoring methods.Joint pathological damage was analyzed by hematoxylin and eosin(HE)staining.The levels of anti-collagen-spe-cific antibodies and the pro-inflammatory cytokine IL-17 were measured by ELISA.The expressions of γδT cells and their subtypes,as well as the secretion level of IL-17,were detected by flow cytometry.Results Dioscin significantly reduced the arthritis severity score in collagen-induced arthritis(CIA)mice,alleviated joint pathological damage,inhibited the production of IL-17 by splenic lymphocytes and the levels of anti-col-lagen-specific antibodies total IgG and IgG3,and de-creased the proportion of γδT cells in the lymph nodes,splenic γδT cells,and the Vδ4+T-cell subset.The level of IL-17 produced by the Vδ4 subtype in the lymph nodes of the intervention groups was lower than that in the model group,but the difference was not sta-tistically significant.Conclusion Dioscin has signifi-cant therapeutic effect on CIA,and its mechanism may be through the inhibition of γδT cells,but it is unlikely to be related to IL-17 derived from γδT cells.

Objective:To deeply understand the experience of neurosurgery nurses on the lack of perioperative nursing for intracranial tumors patients, so as to provide reference for reducing the lack of nursing and improving the quality of nursing and patients′ medical experience.Methods:From December 2023 to February 2024, the neurosurgical nurses of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were selected by the purpose sampling method with maximum differentiation. Semi-structured interviews were conducted with phenomenological research methods. The interview data were transcribed, coded, categorized and described.Results:A total of 17 neurosurgical nurses were enrolled, including 6 males and 11 females, aged 24-45(33.29 ± 6.74) years. Three themes of perioperative nursing lack experience of neurosurgery nurses were obtained, including nursing lack experience (lack of safety nursing, lack of timely nursing, lack of high efficiency nursing, lack of effectiveness nursing, lack of fair nursing, and lack of patient-centered), the physical and mental effects of nursing lack on nurses (impacts of lack of nursing on nurses′ physiology and psychology), and reasons for lack of nursing (personnel, equipment, materials, organization management, environment).Conclusions:Neurosurgical nurses lack of perioperative nursing for patients with intracranial tumor, which has a certain impact on the physical and mental health of nurses, suggesting that neurosurgical nurses should attach great importance to the lack of nursing for patients with intracranial tumor and formulate a scientific and effective management system.

Hypothermia is a clinical syndrome characterized by core body temperature<35℃,caused by significant heat loss from body surface in cold environment.As a systemic cold injury,it can be lethal if treatment is delayed.Emergent diagnosis and treatment of hypothermia are expected to improve the prognosis of patients.In 2005,the U.S.Army Research Institute of Environmental Medicine(USARIEM)issued guidelines for the prevention and management of cold injuries,but there has been no corresponding standard in China.Therefore,Emergency Branch of Chinese Medical Rescue Association,Emergency Medical Equipment Society of China Association of Medical Equipment,Integrated Rehabilitation Medical Branch of Chinese Medical Rescue Association,and Pre-Hospital Emergency Care Working Committee of Chinese Aging Well Association jointly developed the Chinese Expert Consensus on Emergent Treatment of Hypothermia(2025 edition).The consensus covers the pathophysiology,etiology and epidemiology,diagnosis and severity grading,prehospital treatment,and in-hospital treatment of hypothermia,including 15 recommendations in total,aiming to provide guidance for the relevant clinical rescue work.
