ObjectiveTo investigate the association between serum fasting triglyceride glucose-body mass index （TyG-BMI） and new-onset metabolic dysfunction-associated fatty liver disease （MAFLD） within 10 years. MethodsA retrospective analysis was performed for the data of individuals who underwent physical examination in The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University in 2013， 2018， and 2023 and were not diagnosed with MAFLD in 2013， and a total of 1 340 valid subjects were enrolled according to the inclusion and exclusion criteria. The gbmt package in R 4.3.0 was used to construct the dynamic change trajectory model of TyG-BMI， and four different TyG-BMI trajectory groups were determined， i.e.， the low-level group （n=352）， the medium-level group （n=517）， the high-level group （n=314）， and the extremely high-level group （n=157）. The data on general information and blood biochemical parameters were collected from all subjects and were then compared between groups. The chi-square test was used for comparison of categorical data between groups， and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data with heterogeneity of variance between multiple groups. The Cox regression analysis was used to investigate the association between different TyG-BMI trajectories and the risk of MAFLD， and the receiver operating characteristic （ROC） curve was used to assess the value of TyG-BMI in the diagnosis of MAFLD. ResultsThe cumulative incidence rate of MAFLD increased with the increase in the level of TyG-BMI trajectory， with a cumulative incidence rate of 4.83% in the low-level group， 29.98% in the medium-level group， 61.15% in the high-level group， and 83.44% in the extremely high-level group （P<0.001）， and the cumulative incidence rate of MAFLD in men was significantly higher than that in women （51.34% vs 20.67%， P<0.001）. The multivariate Cox regression analysis showed that increases in the levels of TyG-BMI trajectory， uric acid， diastolic blood pressure， hemoglobin， and alanine aminotransferase were independent risk factors for the onset of MAFLD （all P<0.05）， while the increase in high-density lipoprotein cholesterol was an independent protective factor against MAFLD （P<0.001）. After adjustment for confounding factors， the medium-， high-， and extremely high-level groups had a hazard ratio of 4.430 （95% confidence interval ［CI］： 2.660 — 7.377， P<0.001）， 6.937 （95%CI： 4.110 — 11.708， P<0.001）， and 7.989 （95%CI： 4.616 — 13.827， P<0.001）， respectively. The ROC curve analysis showed that TyG-BMI had the highest diagnostic value， with an area under the ROC curve of 0.859 （95%CI： 0.840 — 0.879）， a sensitivity of 79.8%， and a specificity of 76.3%. ConclusionThe risk of MAFLD increases with the increase in the level of TyG-BMI trajectory， and TyG-BMI can be used as a predictive indicator for MAFLD.

ObjectiveTo understand the epidemiological distribution and gene evolutionary variation of influenza A (H3N2) viruses in Fengxian District, Shanghai, in the surveillance year of 2023, and to provide a reference basis for influenza prevention and control. MethodsThe prevalence of influenza virus in Fengxian District in the 2023 influenza surveillance year (April 2023‒March 2024) was analyzed. The hemagglutinin (HA) gene, neuraminidase (NA) gene, and amino acid sequences of 75 strains of H3N2 influenza viruses were compared with the vaccine reference strain for similarity matching and phylogenetic evolutionary analysis, in addition to an analysis of gene characterization and variation. ResultsIn Fengxian District, there was a mixed epidemic of H3N2 and H1N1 in the spring of 2023, with H3N2 being the predominant subtype in the second half of the year, and Victoria B becoming the predominant subtype in the spring of 2024. A total of 75 influenza strains of H3N2 with HA and NA genes were distributed in the 3C.2a1b.2a.2a.2a.3a.1 and B.4 branches, with overall similarity to the reference strain of the 2024 vaccine higher than that of the reference strain of the 2022 and 2023 vaccine. Compared with the 2023 vaccine reference strain, three antigenic sites and one receptor binding site were changed in HA, with three glycosylation sites reduced and two glycosylation sites added; where as in NA seven antigenic sites and the 222nd resistance site changed with two glycosylation sites reduced. ConclusionThe risk of antigenic variation and drug resistance of H3N2 in this region is high, and it is necessary to strengthen the publicity and education on the 2024 influenza vaccine and long-term monitoring of influenza virus prevalence and variation levels.

Objective To explore the potential prognostic factors of patients with acute ischemic stroke(AIS)after undergoing endovascular mechanical thrombectomy and to construct an effective predictive model.Methods A retrospective analysis of clinical data was conducted on 202 patients with anterior circulation large vessel occlusion AIS from 2 stroke centers.All patients received endovascular mechanical thrombectomy treatment,with treatment and follow-up lasting at least 90 d.Basic demographic characteristics,medical records,and baseline blood biomarker data were collected,and the potential prognostic indicators for AIS after 90 d were screened using least absolute shrinkage and selection operator(LASSO)-logistic regression analysis.Results It was found that alcohol drinking(P=0.029),hypertension(P=0.001),diabetes mellitus(P=0.021),stroke or transient ischemic attack(P=0.049),systolic blood pressure on admission(P=0.009),diastolic blood pressure on admission(P=0.038),blood glucose(P=0.003),white blood cell count(P=0.001),neutrophil count(P=0.001),fibrinogen(P=0.010),systemic immune-inflammation index(P=0.008)and neutrophil-to-lymphocyte ratio(NLR)(P＜0.001)were associated with adverse clinical outcomes.Nine significant prognostic determinants were screened through LASSO-logistic regression analysis.Multivariate logistic regression analysis revealed that male sex(P=0.008),smoking history(P=0.013),hypertension(P=0.011),lymphocyte(P=0.028),fibrinogen(P=0.016),and NLR(P＜0.001)were significant predictive factors for poor prognosis in AIS patients after endovascular thrombectomy treatment.The constructed prognostic model had an accuracy of 76.2％,a sensitivity of 78.2％,a specificity of 71.7％,and a positive predictive value of 86.7％.Conclusion The predictive model established in this study can assist clinicians in identifying high-risk patients with AIS who have undergone endovascular thrombectomy,and it provide guidance for formulating individualized treatment strategies.

Purpose To investigate the value of MYB and Notch1 immunohistochemical staining in the differential diagno-sis of classic adenoid cystic carcinoma of the breast(C-AdCC)and solid-basaloid adenoid cystic carcinoma of the breast(SB-AdCC).Methods MYB and Notch1 immunohistochemical staining were performed in 20 cases of C-AdCC,6 cases of SB-AdCC and 65 cases of other breast lesions in the archives of pa-thology department.26 cases of AdCC were detected by FISH,and 6 cases of SB-AdCC were detected by NGS.Results MYB immunohistochemical staining showed that C-AdCC(20/20)was moderately or strongly positive,while SB-AdCC(4/6)was mod-erately or strongly positive.Collagenous spherulosis(5/5)showed focal or diffuse weak positivity;Malignant adenomyoepi-thelioma(3/3)was focally moderately or strongly positive;8 matrix-producing carcinomas and 9 secretory carcinomas and 40 non-specific triple-negative breast cancers were negative.Immu-nohistochemistry of Notch1 showed diffuse moderate positive for SB-AdCC(3/6)and negative for C-AdCC(20/20).3 cases of malignant adenomyoepithelioma,5 cases of collagenous spherulo-sis,8 cases of matrix-producing carcinoma,9 cases of secretory carcinoma and 40 cases of non-specific triple-negative breast cancer were negative.FISH showed MYB gene disruption in C-AdCC(12/19)and NGS showed SB-AdCC(3/6)Notch1 muta-tion.Conclusion Moderately or strongly diffuse expression of MYB and Notch1 by immunohistochemistry can assist in the dif-ferentiation of C-AdCC from SB-AdCC,and it can be further clarified by molecular detection when it is difficult to distinguish malignant adenomyoepithelioma.

ObjectiveTo analyze the surveillance status of acute respiratory tract infection pathogens in Fengxian District of Shanghai, and to determine the pathogen spectrum and epidemiological characteristics of acute respiratory tract infection in the district. MethodsCase surveillance data from Fengxian Central Hospital were collected through the Shanghai Integrated Surveillance System for Acute Respiratory Infections, and respiratory specimens were collected from the 50^th week of 2022 to the 49^th week of 2023 for nucleic acid detection of 25 pathogens and bacterial culture testing. Case surveillance data from Fengxian Central Hospital were collected through the National Influenza Sentinel Surveillance System, and respiratory specimens were collected for nucleic acid detection of 5 pathogens. ResultsThe percentage seeking for medical visits of influenza-like illness (ILI) and severe acute respiratory infection (SARI) were 4.74% and 0.81%, respectively, with epidemic peaks in winter and spring. A total of 1 610 samples were detected, among which 354 were SARI cases, whose age of P₂₅ and P₇₅ quartiles were 44 years and 71 years, respectively, with a positive detection rate of 48.31%. Among the 1 256 ILI cases, the age of P₂₅ and P₇₅ quartiles were 21 years and 39 years, respectively. The positive detection rate of pathogens was 65.04% in 123 ILI cases under comprehensive surveillance of respiratory tract infection and 66.11% in 1 133 ILI cases under influenza surveillance. The positive rates of influenza andSARS-CoV-2 in SARI samples were 12.99% and 29.66%, respectively. The positive rates of influenza and SARS-CoV-2 in ILI case samples were 33.20% and 31.53%, respectively. Influenza virus concentrated in the winter and spring. The ILI and SARI cases had the highest positivity rates in the 6‒14 years old group and 15‒24 years old group, respectively. ConclusionThe main pathogens of respiratory tract infection in Fengxian District of Shanghai were SARS-CoV-2 and influenza virus. Special efforts should be made to monitor respiratory disease pathogens in the population under 24 years old, and surveillance of SARI cases aged ≥60 years should be strengthened. The influenza virus and SARS-CoV-2 are alternating, which is different from the past and requires a change in the previous prevention and control strategies.

Objective:To analyze the performance characteristics of the energy output of defibrillation device at different lifecycle stages of the equipment,and to improve the level of management,so as to ensure the safety and effectiveness of using the device.Methods:A total of 90 defibrillation devices of using 10 types included 861290 and CardioServ(included scrapped devices)during the period of 2015-2022 were retrospectively analyzed.The detected data of energy output of defibrillation device were analyzed as statistical method,and the error of releasing energy was calculated.A total of 36 defibrillation devices that were in the early stages of use(at the first three years of device use)were divided into the first year,the second year and the third year,and the data of energy outputs of devices among three years were compared.The data of the type A and type B defibrillation devices,which were the largest number of devices in the normal stage of use(the middle stage of use),were calibrated according to the energy release in the three years between 2018 and 2000.The difference of releasing energy at the preseted value of 100J between the two types of devices was analyzed.Finally,the errors of energy releases of 8 devices,which energy outputs exceeded the deadline,in the scrap period between 2015 and 2022 were summarized.Results:In the data of three groups of devices in the early stages of use,the differences at the first and second year of device use among 100J,150J and 200J of the energy releases of the preseted values were significant(t=-0.17,-0.17,-0.58,P>0.05).The difference of the measured values between the first and third years of device use was not significant(Z=-0.70,-0.38,-0.86,P>0.05).The results of variance analysis of repeated measurement of the energy releases of the devices in normal stage indicated that the difference of the energy release at 100J preseted point among different types of 41 devices was significant(F=4.40,P<0.05).The energy release of type X defibrillator appeared constantly high,and the relative error increased with the increasing of preseted values.The repeatability of the device was better,and the relationship between preseted energy(x)and release energy(y)conformed to linear relationship(R2=0.9985).In these defibrillation devices that were using,the qualified rate of energy output of>100J preseted point was 97.68%.Conclusion:There is slight difference in the mean value of energy release between different type of defibrillation devices within the qualified range,and the energy release still is a performance indicator that should be highly focused for defibrillation devices.We should combine with the maintenance and repair data of device to conduct in-depth analysis,so as to grasp the operating status of the device,and optimize the strategy of quality control,and ensure the safety of defibrillator in clinical use.
