Background and purpose:The treatment of recurrent,metastatic,and treatment-na?ve advanced cervical cancer remains challenging.Immunotherapy in combination with chemotherapy and targeted therapy has shown preliminary clinical benefits,however,current evidence remains limited.This study aimed to evaluate the impact of camrelizumab combined with chemotherapy and targeted therapy on the prognosis of patients with recurrent,metastatic,and treatment-na?ve advanced cervical cancer.Methods:In this study,we conducted a retrospective analysis of the clinical data from 130 patients with recurrent,metastatic,and treatment-na?ve advanced cervical cancer admitted to Minhang Branch of Fudan University Shanghai Cancer Center from 2019 to 2025.The patients were categorized into the observation group(n=70),which included those who received camrelizumab with or without chemotherapy and targeted therapy,and the control group(n=60),including those who received chemotherapy and targeted therapy.Survival analysis was performed using the log-rank test,and univariate and multivariate Cox regression analyses were conducted to explore prognostic factors.This study was approved by the Ethics Committee of the Minhang Branch of Fudan University Shanghai Cancer Center[Approval number:(2024)Review No.(015)]and all informed consents were exempted.Results:The objective response rate(ORR)in the observation group was 72.9%,and the disease control rate(DCR)was 80.0%,which were significantly higher than those in the control group with an ORR of 20.0%(χ2=36.1,P＜0.001)and a DCR of 40.0%(χ2=21.8,P＜0.001).The median progression-free survival(PFS)in the observation group was not reached,significantly longer than that in the control group of 7.0 months(P＜0.001).Multivariate Cox regression analysis identified camrelizumab treatment as an independent protective factor for PFS(P＜0.001).Age,site of recurrence/metastasis,initial treatment approach,and histopathological type were not significantly associated with PFS.In the observation group,adverse events of grade 3 or higher were reported in 29 patients(41.4%),which primarily included vasculitis,hypothyroidism,hypersensitivity reactions,and diarrhea.Conclusion:The use of camrelizumab significantly improved treatment outcomes and prognosis for patients with recurrent,metastatic,and treatment-na?ve advanced cervical cancer,with significantly improved progression-free survival.Although a certain proportion of patients experienced adverse events of grade 3 or higher,the overall safety profile was acceptable.In clinical practice,immunotherapy offers a more effective treatment option for patients.

Objective To explore the application of the Autoregressive Integrated Moving Average (ARIMA) model in predicting the number of reported hepatitis E cases in Yunnan Province，to use this model to predict the incidence trend of hepatitis E, and to provide reference for the scientific prevention and control of hepatitis E. Methods Monthly reported cases of hepatitis E in Yunnan Province from 2012 to 2021 were collected. The ARIMA model was established using SPSS 27.0, and the model was validated and parameters were optimized with data from January 2022 to December 2022. The optimal fitting model was used to predict the incidence of hepatitis E in 2023. Results Hepatitis E incidence in Yunnan Province showed a certain seasonal distribution, with most cases concentrated from March to August. All parameters of ARIMA(3,1,4)(1,1,1)₁₂ passed statistical tests. The Ljung-Box test showed statistic Q =10.050, P = 0.346, residual sequence was a white noise sequence, and goodness-of-fit index stationary R² was 0.591. The model extrapolation effect was verified with 2022 data, and MAPE was 14.747, indicating that the model extrapolation effect was effective. The number of hepatitis E cases in Yunnan Province in 2023 was expected to be 1,086. Conclusion The ARIMA (3,1,4)(1,1,1)₁₂ model shows good fitting performance for hepatitis E cases in Yunnan Province and can effectively predict short-term disease trends, providing a theoretical basis for formulating prevention and control measures for hepatitis E.

Objective To establish a method for the simultaneous determination of peimine,peiminine,and hupehenine in Juhong pills,to investigate the raw material usage of Fritillaria thunbergii Miq.,and to preliminarily develop a detection approach for identifying adulteration with Fritillaria hupehensis Hsiao et K.C.Hsia.Methods The high-performance liquid chromatography-triple quadruple mass spectrometry(HPLC-MS/MS)was performed on an Agilent Poroshell 120 SB C18 column(2.1 mm×100 mm,2.7 μm)with a mobile phase consisting of acetonitrile-methanol(1∶1)and 0.1%formic acid under gradient elution.The flow rate was set at 0.3 mL·min-1.The column temperature was maintained at 35℃,and the injection volume was 2 μL.Electrospray ionization(ESI)in positive ion mode and multiple reaction monitoring were employed to quantify the three components in 170 batches of Juhong pills.Simulated positive samples with varying adulteration ratios of Fritillaria hupehensis Hsiao et K.C.Hsia were prepared to establish a simple yet efficient detection limit for adulteration.Results Three components showed good linear correlation within their ranges(r≥0.997 5),and the averaged recoveries ranged from 92.0%-106.2%.A total of 61 batches were suspected of Fritillaria thunbergii Miq.adulteration with Fritillaria hupehensis Hsiao et K.C.Hsia in raw material inputs,with the peimine to peiminine ratio below 1.15.Among these samples,27 batches were large honey-bound pills with hupehenine levels of 2.636-9.939 μg·g-1;34 batches were water-honeyed pills showing significantly higher hupehenine contamination at 6.752-48.137 μg·g-1.Conclusion The established method is simple,reliable,and accurate for the quality control of Fritillaria thunbergii Miq.adulteration in Juhong pills without imposing significant additional costs.

A 66-year-old female patient with multiple chronic diseases was on long-term treatment with digoxin, spironolactone, metoprolol, atorvastatin, dapagliflozin, and entecavir, with no abnormality platelet count (PLT). Due to hypertrophic obstructive cardiomyopathy and atrial fibrillation, digoxin was discontinued, and rivaroxaban 15 mg once daily orally was added to prevent thrombosis. Concurrently, furosemide, sacubitril valsartan, meglumine adenosine cyclophosphate, and silibinin was given for cardiac load reducement, blood pressure control and heart failure improvement, myocardial nutrition, and liver function improvement, respectively. After the initiation of this regimen, the patient′s PLT gradually decreased and was 51×10 9/L on day 13. Drug-induced thrombocytopenia was considered, with rivaroxaban being the likely causative agent. Rivaroxaban was then switched to warfarin, methylprednisolone 40 mg was administered intravenously once, and the remaining medications were continued. The patient′s PLT gradually increased. On day 11 after discontinuing rivaroxaban, the PLT was 155×10 9/L. At a 2-week follow-up, PLT of the patient was 169×10 9/L.

Background and Aims:N6-methyladenosine(m6A)epigenetic modification plays a crucial role in post-transcriptional gene expression regulation and various physiological and pathological processes,including tumorigenesis.The m6A reader IGF2BP2 significantly enhances mRNA stability and translation efficiency and is abnormally expressed in multiple cancers.However,the specific biological function of IGF2BP2 in pancreatic cancer remains unclear.Therefore,this study investigated the expression of the m6A reader IGF2BP2 in pancreatic cancer and its effects on pancreatic cancer cell functions.Methods:The expression levels of m6A-related writers,erasers,and readers were analyzed using The Cancer Genome Atlas(TCGA),the Genotype-Tissue Expression(GTEX)database,and the Gene Expression Omnibus(GEO).Kaplan-Meier survival analysis was conducted to assess the relationship between IGF2BP2 expression and the prognosis of pancreatic cancer patients.Immunohistochemistry was used to validate IGF2BP2 expression in clinical specimens of pancreatic cancer tissues and adjacent normal tissues.Functional experiments,including CCK-8 assay,flow cytometry for cell cycle analysis,colony formation assay,and Transwell migration assay,were performed to evaluate changes in cell proliferation,cell cycle distribution,colony formation ability,and migration capacity after IGF2BP2 knockdown in pancreatic cancer cells.Results:TCGA-GTEX and GEO database analyses showed that IGF2BP2 was highly expressed in pancreatic cancer tissues(both P<0.05)and that its high expression was associated with poor overall survival(both P<0.05).Immunohistochemical staining of clinical specimens confirmed that IGF2BP2 protein expression was higher in pancreatic cancer than in adjacent normal tissue.Functional experiments demonstrated that IGF2BP2 knockdown significantly reduced the proliferation ability of pancreatic cancer cells,arrested more cells in the G0-G1 phase,decreased colony formation,and impaired cell migration(all P<0.05).Conclusion:The m6A reader IGF2BP2 is highly expressed in pancreatic cancer tissues and is closely associated with poor prognosis in patients with this disease.Its mechanism of action may be related to the promotion of cancer cell growth and migration.
