Objective: To investigate the intentions of mothers of ageappropriate girls in Qingdao to vaccinate their daughters against human papillomavirus (HPV), so as to provide theoretical guidance for targeted health education in the future. Methods: A multistage random sampling method was adopted to conduct a crosssectional study among 2 244 mothers of girls aged 12-14 years in Qingdao from March to December 2023. The Mann-Whitney U test was used for group comparisons, and Logistic regression was performed to analyze the factors that influenced maternal intention to vaccinate their ageappropriate daughters against HPV. Results: Among the surveyed mothers, 89.22% (n=2 002) intended to vaccinate their daughters against HPV, and 68.58% (n=1 539) had fully vaccinated or had plans to complete it for themselves. The knowledge score of mothers intended to vaccinate their daughters was 10 (8, 11). The multivariate Logistic regression analysis showed that mothers aged >45 years (OR=0.19), those with an annual family income of 60 000-<150 000 yuan (OR=0.65), 150 000-<300 000 yuan (OR=0.58), 300 000-500 000 yuan (OR=0.22), and those with higher knowledge scores (OR=0.90) were more likely to vaccinate their daughters (P<0.05). Mothers with a junior college or undergraduate degree (OR=1.66), those who never or occasionally screened for HPV (OR=1.58), those who were intended to be vaccinated, not planning to complete the fullcourse vaccination, or overaged and unvaccinated (OR=7.13), those who were not concerned about their daughters HPV infection (OR=2.54), and those whose daughters were not in adolescence (OR=1.93) were less intended to vaccinate their daughters (P<0.05). The primary reasons for vaccine hesitancy were vaccine safety concerns (65.06%), followed by the belief of mothers that "the children is to young, and can be vaccinated when they are older" (13.25%). Conclusions Mothers of eligible girls in Qingdao have relatively higher intentions to vaccinate their daughters against HPV, and willingness is influenced by factors such as the mothers vaccination status, knowledge level, and daughters development stage. It is recommended to strengthen targeted health education, improve the cognitive level and acceptance of mother, and increase the vaccination rate of HPV vaccines.

Objective: To evaluate the application of blood conservation measures in obstetric patients with different red blood cell transfusion volumes and to assess the impact of different transfusion volumes on postpartum outcomes. Methods: A retrospective investigation was conducted on 448 obstetric patients who received blood transfusions at the Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. Patients were divided into four groups (1-2 units group, 3-4 units group, 5-6 units group, and >6 units group) based on the volumes of red blood cells (RBCs) transfused during and within 7 days after delivery. The maternal physiological indicators, pre- and postpartum laboratory test indicators, obstetric complications, application of blood conservation measures, use of blood products, and postpartum outcomes were reviewed. The clinical characteristics, application of blood conservation measures, and their impact on postpartum outcomes were compared among different transfusion groups. Results: There were statistically significant differences in the multivariate logistic analysis of history of previous cesarean section (OR=1.781), eclampsia/pre-eclampsia/(OR=1.972) and postpartum blood loss>1 000 mL（OR=1.699）(P<0.05) among different transfusion groups. In terms of blood conservation measures, the more RBCs transfused, the higher the rate of mothers receiving blood conservation measures such as balloon occlusion, arterial ligation, autologous blood transfusion with a cell saver, and hysterectomy. With the increase in the volume of RBCs transfusion, the demand for fresh frozen plasma（FFP）, cryoprecipitate, and platelet transfusions also increased. The hospitalization days for the four groups of parturients were 6.0 (4.0-9.0), 7.5 (5.0-14.8), 7.0 (4.5-13.0) and 11.0 (9.0-20.5), respectively (P<0.05) and the rates of ICU transfer were 2.0% (5/250), 9.4% (12/128),18.2% (6/33) and 51.4% (19/37), respectively (P<0.05). Both increased significantly with the increase in the volume of RBCs transfusion, and the differences between groups were statistically significant. Conclusion: Parturients who received higher volume of RBCs had multiple risks factors for bleeding before childbirth, had higher postpartum blood loss, and had a higher rate of application of various blood conservation measures. In addition, an increase in the volume of RBCs transfusion may have adverse effects on postpartum recovery.

Objective To observe the value of right ventricular free wall longitudinal strain(RVFWLS)to pulmonary artery systolic pressure(PASP)ratio(RVFWLS/PASP)for evaluating systolic function of right ventricle(RV)in patients with hypertrophic cardiomyopathy(HCM).Methods Fifty-two HCM patients were retrospectively collected and divided into group A(RVFWLS/PASP≤0.75,n=26)and B(RVFWLS/PASP＞0.75,n=26)according to median RVFWLS/PASP.Meanwhile,26 healthy individuals were included as control group.Parameters of echocardiography and speckle tracking imaging(STI)were obtained and compared among 3 groups.The correlations of RVFWLS/PASP and other parameters were analyzed with linear regression.Results In group A and B,left ventricular ejection fraction(LVEF),RV septal longitudinal strain(RVSepLS),RVFWLS,RV end-diastolic volume index(RVEDVi),RV stroke volume(RVSV),RV fractional area change(RVFAC)and left ventricular global longitudinal strain(LVGLS)were all lower,while the ratio of peak E blood flow velocity at mitral orifice diastole to early mitral intervalal annulus diastole velocity(E/e′)were higher than those in control group(all adjusted P＜0.05).Compared with group B and control group,group A had higher PASP but lower RV ejection fraction(RVEF)(all adjusted P＜0.05).Furthermore,RVFWLS and LVGLS were both lower in group A than in group B(both adjusted P＜0.05).Linear regression analysis showed that RVSepLS and RVEF were independently linearly related to RVFWLS/PASP(both P＜0.05).Conclusion RVFWLS/PASP could be used to monitor changes of RV systoic function in HCM patients at early stage.

Objective:To review the clinicopathological features of TFE3-rearranged renal cell carcino-ma(TFE3-RCC)with venous tumor thrombus(VT)(TFE3-VT),to explore treatment strategies and to prognostic characteristics,and to provide diagnostic and therapeutic references for TFE3-VT patients.Methods:Patients who underwent surgery at Department of Urology,Peking University Third Hospital from January 2013 to January 2024 were enrolled,including three cohorts:Pathologically confirmed TFE3-VT patients,TFE3-RCC patients without VT(TFE3-non-VT),and non-TFE3-rearranged renal cell carcinoma patients with VT(non-TFE3-VT).Clinical history,imaging data,pathological data,and follow-up records were collected.Primary and secondary endpoints were progression-free survival(PFS)and overall survival(OS),respectively.(1)Baseline characteristics were compared between the TFE3-VT and TFE3-non-VT patients.Normally distributed continuous variables were expressed as mean±SD and compared using Student's t-test;non-normally distributed variables were expressed as M(P25,P75)and analyzed with Mann-Whitney U test;categorical variables were described as frequency and percentage[n(％)]and compared by x2 test or Fisher's exact test.(2)Clinical history,radiological presenta-tions,surgical data,and histopathological features of the TFE3-VT patients were comprehensively charac-terized.(3)Survival analysis was performed for the TFE3-VT patients.Follow-up data of the TFE3-VT patients were described in detail,and their survival outcomes were compared with the TFE3-non-VT and non-TFE3-VT patients.When compared with the TFE3-non-VT counterparts,Kaplan-Meier method was used to generate PFS and OS curves among:(1)the TFE3-RCC patients across clinical stages Ⅰ-Ⅳ;(2)TFE3-VT versus TFE3-non-VT cohorts;(3)stage Ⅲ subgroups of the TFE3-VT and TFE3-non-VT patients.Intergroup survival differences were statistically evaluated using Log-rank tests.For comparisons with the non-TFE3-VT patients,a 1∶1 propensity score matching(PSM)was implemented to balance baseline characteristics between the two cohorts.Post-matching Kaplan-Meier curves were generated to compare PFS and OS between the matched groups,with Log-rank tests employed to determine statistical significance of survival disparities.All statistical analyses were conducted with R software(v 4.2.3),and two-tailed P＜0.05 was considered statistically significant.Results:The study included 45 TFE3-RCC patients:13 TFE3-VT and 32 TFE3-non-VT cases.Additionally,523 non-TFE3-VT patients were enrolled.Among the 13 TFE3-VT patients,9 were female(69.2％)and 4 male(30.8％),with a mean age of(37.9±14.4)years,mean BMI of(22.2±3.5)kg/m2,median age-adjusted Charlson comorbidity index(aCCI)of 1.0(0.0,1.0),and preoperative creatinine level of(75.3±15.9)μmol/L;tumors were located in the left kidney in 7 patients(53.8％)and right kidney in 6(46.2％);preoperative distant metastasis(M1 stage)was present in 6 patients(46.2％),while 7(53.8％)showed no metastasis;VT distribution by Mayo level comprised 7 cases(53.8％)at level 0,1 case each at levels Ⅰ and Ⅳ(7.7％respectively),and 2 cases each at levels Ⅱ and Ⅲ(15.4％respectively);surgical approaches comprised open surgery(n=2,15.4％),laparoscopic surgery(n=6,46.1％),and robot-assisted laparoscopic surgery(n=5,38.5％);mean operative time was(273±79)min,and intraoperative blood loss was(722±570)mL;mean maximum tumor diameter was(10.8±2.4)cm.All the 13 patients underwent TFE3 protein immunohistochemistry(IHC)staining,with 7 confirmed by fluorescence in situ hybridization(FISH).Tumor recurrence or metastasis occurred in 11 patients(84.6％),and 9(69.2％)patients died during follow-up.Median PFS was 4 months(1 year PFS rate:31％),and median OS was 13 months(1 year OS rate:54％).Survival analysis of 45 TFE3-RCC pa-tients revealed statistically significant differences in PFS and OS across all the clinical stages(P＜0.001).The TFE3-VT patients exhibited significantly worse PFS and OS than the TFE3-non-VT patients(P＜0.001),with persistent significance in stage Ⅲ subgroup analysis(P＜0.05).After PSM,TFE3-VT pa-tients showed significantly inferior PFS compared with non-TFE3-VT(P=0.01),though no significant difference was shown between the OS curves(P=0.11).Conclusion:TFE3-VT predominantly occurs in young females with frequent preoperative metastases.Strongly-positive staining of TFE3 protein in IHC stai-ning and red-green split signals in FISH tests are reliable diagnostic markers.TFE3-VT patients exhibit in-ferior survival compared with TFE3-non-VT patients and earlier progression than non-TFE3-VT patients.

Objective:This current study aims to explore the approaches for constructing a professional clinical research system within the context of research ward development, with the ultimate objective of providing valuable guidance for the establishment and development of proficient clinical research teams.Methods:Through a comprehensive case analysis, integrating the practical experiences from clinical trials conducted in the research ward of a Class-A tertiary hospital in Beijing, along with an extensive review of relevant literature and policy studies, this paper examined the current state of domestic clinical research implementation teams. Subsequently, a series of strategies were devised to build and foster professional clinical research teams and to explore corrective measures for cultivating a dynamic professional clinical research talent ecosystem.Results:The development of full-time clinical research teams in China was rather slow, and there was a lack of mature clinical trial teams training blueprints. Drawing on the practical experience accumulated during the establishment of a professional clinical research team in a leading hospital in Beijing, it was crucial to attach utmost importance to the optimal allocation of human and material resources. This required the systematic training of principal investigators, coordinating researchers, and research assistants, as well as the setting up of a comprehensive support system, an advanced scientific research team, and a quality control unit. Moreover, the standardization of operational models of both domestic and foreign research institutions, along with the implementation of corresponding support and incentive mechanisms, and the strengthening of training and continuing education frameworks were equally significant.Conclusions:During the process of assembling a full-time clinical research team, it is of utmost significance to cultivate professional principal investigators, coordinating researchers, and research assistants. Complemented by the establishment of a comprehensive support team, a scientific research team, and a quality control team, along with corresponding support and incentive mechanisms, this is crucial for constructing a professional clinical research execution team and a sustainable talent ecosystem in the research ward. Eventually, this will drive the efficient and high-quality progress of China's pharmaceutical industry.

The National Institute on Aging-Alzheimer's Association(NIA-AA)released the"Revised criteria for diagnosis and staging of Alzheimer's disease"in 2024,representing a significant update following the 2011 and 2018 frameworks.This new standard aims to advance Alzheimer's disease diagnosis and treatment from a"clinical-pathological"model to a"precision biology"era,improving early diagnosis rates and guiding precise therapeutic interventions.Nuclear medicine molecular imaging plays an irreplaceable role in Alzheimer's disease diagnosis and staging,with key updates in the 2024 standard being the replacement of traditional clinical diagnosis with biological definitions and the hierarchical classification of biomarkers.This article focuses on interpreting the core positioning and clinical application value of multimodal imaging technologies within the new standard framework,particularly the critical roles of amyloid β-protein PET and tau PET in early diagnosis,biological staging and treatment monitoring of Alzheimer's disease,aiming to provide guidance for clinical practice.

Objective:To analyze the clinical characteristics, therapeutic responses, and survival outcomes of patients with lymphocytic variant hypereosinophilic syndrome (L-HES) .Methods:We retrospectively reviewed clinical data from 16 consecutive patients diagnosed with L-HES at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences, between July 2019 and October 2024. A control group of 65 patients with idiopathic hypereosinophilic syndrome (iHES), diagnosed during the same period, was used for comparison. Clinical and laboratory characteristics, therapeutic responses, and survival outcomes were compared between the two groups.Results:The most frequently involved organs at presentation in patients with L-HES were the skin (75.0%), gastrointestinal tract (25.0%), respiratory tract (18.8%), lymph nodes (18.8%), heart (12.5%), and spleen (6.3%). Compared with iHES patients, patients with L-HES had a significantly higher incidence of skin involvement ( P=0.016), with no statistically significant differences observed in the involvement of other organs. No statistically significant differences were found in complete blood count parameters between the two groups. Multiparameter flow cytometry revealed that the median percentage of CD3 -CD4 + T cells in the peripheral blood of patients with L-HES was 4.08% ( IQR: 1.64%-32.78%), with a median absolute count of 0.10 (0.05-0.55) ×10 9/L. Serum immunoglobulin E (IgE) levels were significantly higher in the L-HES group than in the iHES group ( P<0.001). Clonal rearrangement of T-cell receptor genes was detected in 75.0% of patients with L-HES. After diagnosis, 14 patients with L-HES received glucocorticoids as first-line therapy, yielding an overall response rate of 92.9%. During glucocorticoid tapering, 11 patients experienced recurrent eosinophilia or worsening of clinical symptoms. Three patients received interferon-alpha as a second-line therapy, with two achieving complete remission. After a median follow-up of 16 months ( IQR: 8-28 months), one patient died of cardiac insufficiency 8 months after diagnosis, and no cases of lymphoma transformation were observed. The 2-year overall survival rate was (91.7±8.0) %, which did not significantly differ from that of the iHES group (96.2±2.6) % ( P=0.746) . Conclusions:Patients with L-HES generally have a favorable prognosis and are often characterized by skin involvement and significantly elevated serum IgE levels at diagnosis. They typically respond well to glucocorticoid therapy, although relapse is common during dose tapering. Interferon-alpha may serve as an effective second-line therapeutic option.

Objective: To systematically evaluate the association between maternal adverse childhood experiences (ACEs) and offspring social behavior, so as to provide a theoretical basis for further research on intergenerational social behavioral development. Methods: Relevant research literature about maternal ACEs and the development of children s maladaptive social behaviors were collected, from China National Knowledge Infrastructure (CNKI), VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, Embase and SpringLink databases, covering the period from the inception of each database to May 2025. The Chinese database matched and searched through three groups of keywords: "Pregnant women" "Mothers" and "Women"; "Bad childhood experience" "Bad early experience" and "Bad adolescent experience"; "Children" "Teenagers" "Children s behavior" "Children s development" "Teenagers behavior" "Internalized behavior" and "Externalized behavior". The English database was searched by three groups of keywords: "Female" "Pregnant women" "Mothers"; "Adverse childhood experiences" "Adverse early childhood experiences" "Adverse experiences of adolescent"; "Child behavior" "Child development" "Adolescent behavior" "Internalized behaviors" "Externalized behaviors". The selected literature was evaluated for quality and data extraction, with OR and 95% CI as effect indicators. Stata 16.0 software was used for heterogeneity testing, subgroup analysis, and publication bias analysis. Results: A total of 14 studies involving 64 302 mother-child pairs were included. The Meta analysis results showed a significant correlation between maternal ACEs and both offspring maladaptive internalized behaviors ( OR=1.75, 95%CI=1.42-2.15, P <0.01) and externalized behaviors ( OR=1.82, 95%CI=1.51-2.20, P <0.01). The results of subgroup analyses showed that in different regions[internalized behaviors:domestic, foreign OR (95% CI )=2.03(1.49-2.76), 1.55(1.19-2.03); externalized behaviors: domestic, foreign OR (95% CI )=2.41(1.52-3.82), 1.65(1.36-2.01)], study type[internalized behaviors: cohort study, cross sectional study OR (95% CI )=1.64(1.34-2.00), 1.85(1.30-2.65); externalized behaviors: cohort study, cross sectional study OR (95% CI )=1.76(1.46-2.12), 2.12(1.40-3.20)], sample size [internalized behaviors: ≥4 000, <4 000 pairs OR (95% CI )=1.69(1.13-2.55), 1.77( 1.41 -2.24); externalized behaviors: ≥3 000, <3 000 pairs OR (95% CI )=1.72(1.37-2.17), 2.13(1.44-3.15)], there were significant and positive association between mothers ACEs and children s internalizing and externalizing behaviors (all P <0.05). Conclusion A substantial positive association exists between maternal ACEs and the development of offspring maladaptive internalized and externalized behaviors, but the result needs to be continued to be validated by more research.

Objective:To establish a predictive model for the risk of cognitive impairment in patients with hypertension.Methods:Data were obtained from the China Health and Retirement Longitudinal Study(CHARLS),and 17 indicators were analyzed,including demographic features,behavioral factors,and health status.The study cohort was randomly divided into a training set(n=2 918)and an internal validation set(n=1 249)at a ratio of 7∶3,and 1 457 patients with hypertension who were treated in Chongqing Traditional Chinese Medicine Hospital from January to December 2024 were included as an external validation set.The least absolute shrinkage and selection operator regression analysis was used to identify predictive variables,and 10-fold cross-validation was used to determine the optimal model.A logistic regression model was used to investigate the risk factors for cognitive impairment in patients with hypertension,and then a nomogram prediction model was established.The calibration curve was used to assess the accuracy of the model,and the area under the ROC curve(AUC)and the decision curve analysis were used to assess the predictive performance of the model.Results:A total of 4167 hypertensive patients aged≥45 years were included from the CHARLS database,among whom 668 had cognitive impairment.The multivariate logistic regression analysis showed that age(odds ratio[OR]=1.408,95%CI=1.040-1.056),sex(OR=0.570,95%CI=0.492-0.660),body mass index(OR=0.931,95%CI=0.914-0.948),educational level(OR=0.235,95%CI=0.200-0.277),place of residence(OR=1.674,95%CI=1.447-1.936),physi-cal activity(OR=0.459,95%CI=0.373-0.562),depression(OR=1.386,95%CI=1.198-1.604),and total cholesterol level(OR=0.997,95%CI=0.995-0.999)were predictive variables.The ROC curve analysis showed that the nomogram model had good performance,with an AUC of 0.814(95%CI=0.802-0.826)in the training set,0.817(95%CI=0.788-0.846)in the internal validation set,and 0.725(95%CI=0.699-0.752)in the external validation set.Conclusion:The nomogram model developed in this study can effectively predict the risk of cognitive impairment in Chinese patients with hyperten-sion and has a good application value.

Objective:To dynamically assess liver fibrosis using magnetic resonance elastography (MRE) and explore factors associated with fibrosis reversal in patients with metabolic dysfunction-associated steatohepatitis (MASH).Methods:This study included data from patients diagnosed with MASH by liver biopsy who underwent at least two MRE examinations. Patients were divided into a fibrosis reversal group and a non-reversal group according to whether MRE values decreased by 20% during follow-up. Differences in clinical data between the groups were compared using analysis of variance, the Kruskal-Wallis test, and the chi-square test. Univariate and multivariate logistic regression analyses were used to explore independent risk factors for fibrosis reversal in MASH.Results:A total of 46 cases were included in this study (mean age 50.1±12.3 years, BMI 26.1±3.1 kg/m2). Among them, the reversal group accounted for 26.1%. The rate of decrease in MRI proton density fat fraction (PDFF) was significantly higher in the reversal group (-50.0% vs. -8.1%, P=0.001) than in the non-reversal group between the two MRE examinations. The reversal group showed a more significant change rate of decreases in fasting insulin (-37.3% vs. -3.6%, P=0.011), insulin resistance index (-38.6% vs. -6.5%, P=0.044), and ALP (-24.9% vs. 0, P=0.004). Multivariate logistic regression analysis indicated that the rate of change in MRI PDFF was an independent predictor of fibrosis reversal ( OR=0.96, 95% CI: 0.92-1.00, P=0.046). Conclusion:A decrease in MRI proton density fat fraction levels is independently associated with liver fibrosis reversal in MASH, suggesting that intervention targeting liver fat content may be an effective treatment strategy.
