Objective To compare the effects of different doses of budesonide and formoterol fumarate powder for inhalation combined with montelukast sodium tablet in the treatment of cough variant asthma(CVA)and the improvement of airway function and inflammatory factors.Methods Elderly patients with cough variant asthma were randomly divided into group A and group B.Both groups of patients received budesonide and formoterol fumarate powder for inhalation combined with montelukast sodium tablet.Group A was given budesonide and formoterol fumarate powder for inhalation(Ⅱ),2 inhalation per time,twice a day;Group B was given budesonide and formoterol fumarate powder for inhalation,4 inhalation per time,twice a day;budesonide fumatrol inhalation powder mist for continuous treatment for 6 months,and montelukast sodium tablet 10 mg once a day for at least 3 months.The nighttime cough scores of the two groups were compared before treatment and after treatment.The percentage of forced expiratory volume in one second(FEV1)in the predicted value,the maximum mid expiratory flow(MMEF),the fractional exhaled nitric oxide(FeNO),interleukin-5(IL-5)and eosinophils were compared between the two groups.The incidence of adverse drug reactions and the recurrence rate within 1 year were compared between the two groups.Results A total of 45 cases were enrolled in both the group A and the group B.At 9 months after treatment,the nocturnal cough scores of the group A and the group B were(0.93±0.42)and(0.65±0.29)points,respectively;the percentage of FEV1 in the predicted value were(97.75±9.67)％and(100.93±11.06)％,respectively;the MMEF values were(2.81±1.04)and(3.08±1.09)L·s-1,respectively;the FeNO values were(18.94±9.75)and(15.94±7.96)ppb,respectively;the IL-5 levels were(10.88±7.06)and(8.11±5.56)pg·mL-1,respectively.The above indicators in group B showed statistically significant differences compared to group A(all P＜0.05).The total incidence of adverse drug reactions in group A and group B were 8.89％(5 cases/45 cases)and 13.33％(6 cases/45 cases),respectively.The recurrence rates was 15.56％(7 cases/45 cases)and 13.33％(6 cases/45 cases),respectively.There was no statistically significant difference in the above indicators between group B and group A(all P＞0.05).Conclusion For elderly patients with CVA,higher dose of budesonide and formoterol fumarate powder for inhalation combined with montelukast sodium tablet can better improve cough symptoms,reduce the level of airway hyperresponsiveness and inflammatory factors,reduce the recurrence rate,and the patients are well tolerated.

Objective:To investigate the impact of the interval between neoadjuvant immunotherapy combined with chemotherapy(nICT) and surgery on pathological outcomes and prognosis in patients.Methods:This is a retrospective cohort study. A total of 115 patients with locally advanced esophageal squamous cell carcinoma who underwent nICT followed by sequential surgery at Department of Thoracic Surgery, Peking University People′s Hospital or Department of Thoracic Surgery, the First Affiliated Hospital of Zhengzhou University from January 2020 to April 2024 were included. Among them, 99 were male and 16 were female, with an age of ( M(IQR)) 65 (11) years (range:45 to 81 years). All patients received 2 to 6 cycles of paclitaxel plus platinum-based doublet chemotherapy combined with PD-1 immune checkpoint inhibitors. The resectability of tumors was assessed based on CT scans of the chest and abdomen, and surgical approaches included Sweet surgery, Mckeown surgery, and Ivor-Lewis surgery. Patients were divided into a short-interval group (4 to <6 weeks) and a long-interval group (6 to 12 weeks) based on the interval between neoadjuvant immunochemotherapy and surgery. General patient data, surgical details, pathological response, and prognosis were collected and analyzed. Data comparisons were performed using independent sample t-test, Mann-Whitney U test, χ 2 test, or Fisher′s exact test. Multivariate logistic regression analysis was used to identify independent factors influencing pathological complete response (pCR). Survival analysis was conducted using the Kaplan-Meier method and Log-rank test. Results:There were no significant differences in baseline characteristics, neoadjuvant treatment details, surgical outcomes, or postoperative complications between the long-interval group and the short-interval group (all P>0.05). Multivariate Logistic regression analysis revealed that, among clinical factors, interval between neoadjuvant immunochemotherapy and surgery was significantly associated with pCR (long-interval group vs. short-interval group: OR=4.14, 95% CI:1.63 to 10.50, P=0.003). The pCR rate was higher in the long-interval group (43.6% vs. 17.1%, χ2=6.48, P=0.011). Survival analysis showed no significant differences in overall survival ( P=0.094) or disease-free survival ( P=0.840) between the two groups. Conclusion:Appropriately extending the surgical interval after neoadjuvant immunochemotherapy maybe lead to a higher pCR rate, without increasing surgical difficulty or damaging prognosis.

Objective:To establish venetoclax-resistant acute myeloid leukemia(AML)cell lines,assess the sensitivity of venetoclax-resistant cell lines to the BCL-2 protein family,and investigate their resistance mechanisms.Methods:CCK-8 method was used to screen AML cell lines(MV4-11,MOLM13,OCI-AML2)that were relatively sensitive to venetoclax.Low concentrations of venetoclax continuously induced drug-resistance development in the cell lines.Changes in cell viability and apoptosis rate before and after resistance development were measured using the CCK-8 method and flow cytometry.BH3 profiling assay was performed to anayze the transform of mitochondrion-dependent apoptosis pathway as well as the sensitivity of resistant cell lines to BCL-2 family proteins and small molecule inhibitors.Real-time fluorescence quantitative PCR(RT-qPCR)was utilized to examine changes in the expression levels of BCL-2 protein family members in both venetoclax-resistant cell lines and multidrug-resistant patients.Results:Venetoclax-resistant cell lines of MV4-11,MOLM13,and OCI-AML2 were successfully established,with IC50 values exceeding 10-fold.Under the same concentration of venetoclax,the apoptosis rate of resistant cells decreased significantly(P＜0.05).BH3 profiling assay revealed that the drug-resistant cell lines showed increased sensitivity to many pro-apoptotic proteins(such as BIM,BID and NOXA).RT-qPCR showed significantly upregulated MCL1 and downregulated NOXA1 were detected in drug-resistant cell lines.Expression changes in MCL1 and NOXA1 in venetoclax-resistant patients were consistent with our established drug-resistant cell line results.Conclusion:The venetoclax-resistant AML cell lines were successfully established through continuous induction with low concentrations of venetoclax.The venetoclax resistance resulted in alterations in the mitochondrial apoptosis pathway of the cells and an increased sensitivity of cells to pro-apoptotic proteins BIM,BID,and NOXA,which may be associated with the upregulation of MCL1 expression and downregulation of NOXA1 expression in the drug-resistant cells.

BACKGROUND:silencing information regulatory 1(SIRT1)regulates the function of related proteins in chondrocytes in a deacetylated manner and participates in chondrocyte proliferation and differentiation,thereby promoting cartilage defect repair. OBJECTIVE:To screen for signaling pathways with unclear action status after SIRT1 gene knockdown in chondrocytes,as well as diseases or functions that produce changes using high-throughput technology. METHODS:ATDC5 chondrocytes from mice in logarithmic growth phase were divided into two groups:the cells were transfected with SIRT1 gene knockdown negative control lentivirus in control group and SIRT1 gene knockdown lentivirus in experimental group.GeneChip? Mouse Genome 430 2.0 Array was used to detect the mRNA expression at 72 hours after transfection.Applied bioinformatics technology was also used to screen for unclear activation or inhibition signaling pathways and their related factors.Moreover,enrichment of disease or function modules was analyzed. RESULTS AND CONCLUSION:After knocking down the SIRT1 gene,there were 245 signaling pathways with unclear activation or inhibition status in the mouse ATDC5 chondrocytes.According to the ranking of-Log(P-value),we reported the factors in the top 20 signaling pathways with unclear activation or inhibition status,including IGFBP4,TGFBR1,CTGF,COL4A5,LHX2,IL1RL1,and KLF6.According to the ranking of-Log(P-value),there were significant changes in 14 disease or function modules,including cellular growth and proliferation,organism survival,cell death and survival.According to the number of differentially expressed genes,there were significant changes in three disease or function modules,including organismal injury and abnormalities,cancer,and cell death and survival.According to the comprehensive ranking of-Log(P-value)and the number of differentially expressed genes,the disease or function module related to intrinsic immune response was significantly activated.

Objective To develop a multi-modal deep learning method for automatic classification of immune-mediated glomerular diseases based on images of optical microscopy(OM),immunofluorescence microscopy(IM),and transmission electron microscopy(TEM).Methods We retrospectively collected the pathological images from 273 patients and constructed a multi-modal multi-instance model for classification of 3 immune-mediated glomerular diseases,namely immunoglobulin A nephropathy(IgAN),membranous nephropathy(MN),and lupus nephritis(LN).This model adopts an instance-level multi-instance learning(I-MIL)method to select the TEM images for multi-modal feature fusion with the OM images and IM images of the same patient.By comparing this model with unimodal and bimodal models,we explored different combinations of the 3 modalities and the optimal methods for modal feature fusion.Results The multi-modal multi-instance model combining OM,IM,and TEM images had a disease classification accuracy of(88.34±2.12)%,superior to that of the optimal unimodal model[(87.08±4.25)%]and that of the optimal bimodal model[(87.92±3.06)%].Conclusion This multi-modal multi-instance model based on OM,IM,and TEM images can achieve automatic classification of immune-mediated glomerular diseases with a good classification accuracy.

Autism spectrum disorder (ASD) is a range of neurodevelopmental diseases characterized by social dysfunction and stereotypic behaviors. The etiology of ASD remains largely unexplored, resulting in a diverse array of described clinical manifestations and varying degrees of severity. Currently, there are no drugs approved by a supervisory organization that can effectively treat the core symptoms of ASD. Childhood and adolescence are crucial stages for making significant achievements in ASD treatment, necessitating the development of drugs specifically for these periods. Based on the drug targets and mechanisms of action, it can be found that atypical psychotropic medications, anti-inflammatory and antioxidant medications, hormonal medications, ion channel medications, and gastrointestinal medications have shown significant improvement in treating the core symptoms of ASD in both children and adolescents. In addition, comparisons of drugs within the same category regarding efficacy and safety have been made to identify better alternatives and promote drug development. While further evaluation of the effectiveness and safety of these medications is needed, they hold great potential for widespread application in the clinical treatment of the principal symptoms of ASD.
