Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Objective To explore a novel method for early lung cancer screening based on exhaled breath analysis. Methods This study enrolled patients with suspected pulmonary malignancies and healthy individuals undergoing physical examinations at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine (Qingchun and Qiantang campuses) from September 2023 to June 2024. Enrolled subjects were categorized into a lung cancer group, a benign nodule/tumor group, and a healthy control group. Exhaled breath samples were collected using a sensor array constructed from multiple graphene composite materials to capture breath fingerprints. Based on the collected data, screening and diagnostic models for lung cancer were developed and their performance was evaluated. Results A total of 4 580 subjects were included. Among them, 3 195 were pathologically diagnosed with pulmonary malignancies, including 1 394 males and 1 801 females with a mean age of (58.93±12.37) years, 599 were diagnosed with benign nodules/tumors including 339 males and 260 females with a mean age of (57.10±11.06) years, and 786 were healthy controls with no pulmonary nodules detected on chest CT including 420 males and 366 females with a mean age of (29.75±9.32) years. There were 4 031 patients in the training set and 549 patients in the external testing set. The screening model for high-risk populations (distinguishing patients with lung cancer/high-risk pulmonary nodules from healthy individuals) demonstrated excellent performance, with an area under the receiver operating characteristic curve (AUC) of 0.926. At the optimal Youden’s index (cutoff threshold of 63.5%), the external testing set achieved a specificity of 85.2%, a sensitivity of 88.4%, and an accuracy of 86.8%. The diagnostic model (distinguishing patients with lung cancer/premalignant lesions from those with benign pulmonary nodules/healthy individuals) achieved an AUC of 0.818. At its optimal Youden’s index (cutoff threshold of 47.0%), the external testing set showed a specificity of 71.7%, a sensitivity of 77.3%, and an accuracy of 74.5%. Conclusion The non-invasive breath analysis platform based on a sensor array, developed in this study, can achieve rapid and relatively accurate lung cancer screening by analyzing breath fingerprints. This confirms the feasibility of this technology for early lung cancer screening and holds promise for facilitating the early detection and intervention of lung cancer.

ObjectiveTo review the application of the International Classification of Functioning, Disability and Health (ICF) in the field of visual impairment (VI) rehabilitation. MethodsLiterature related to ICF and VI rehabilitation was retrieved from PubMed, Web of Science, CNKI, Wanfang Data, and VIP from inception to May, 2026. Standards and policy documents related to VI published before May, 2026 were retrieved from the National Standards Full-text Disclosure System of the Standardization Administration of China, the China Disabled Persons' Federation and the Chinese Government Portal. Following PRISMA-ScR, based on the three-dimensional ICF framework, an integrated analysis was conducted from the dimensions of theory, practice and policy. ResultsA total of 17 articles involving 2 648 participants, and four domestic VI assessment standards and one guideline were included. At the theoretical level, domestic VI standards showed the highest alignment with the ICF dimension of body functions, while the coverage of the activities and participation dimension was uneven, and the coverage of the environmental factors dimension was the weakest. At the practical level, the ICF was primarily used for developing assessment tools, conducting clinical evaluations, implementing interventions and exploring service models. At the policy level, the overall orientation of domestic special education and medical insurance payment aligned with the ICF concept of whole person rehabilitation, yet specific implementation rules remained to be formulated. ConclusionICF provides a comprehensive and systematic approach for integrating the VI rehabilitation system in China, demonstrating significant application value in standard construction, clinical practice optimization and policy refinement.

ObjectiveTo investigate the mechanism by which Sini San (SNS) treats liver fibrosis through regulating the polarization of intrahepatic Kupffer cells. MethodsSixty SPF-grade male Balb/c mice were randomized into blank control, model, silymarin (0.2 g·kg-1), and low-, medium-, and high-dose (2.93, 5.85, 11.70 g·kg-1, respectively) SNS groups. A mouse model of liver fibrosis was induced by intraperitoneal injection of CCl4. After 5 weeks of administration, the body mass, liver pathological changes [Hematoxylin and Eosin (HE), Masson, and Sirius red staining], serum biochemical indicators [alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT)], liver fibrosis markers [procollagen type Ⅲ (PCⅢ), laminin (LN), and hyaluronic acid (HA)], inflammatory cytokines [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and interleukin-10 (IL-10)], and fibrosis-related proteins [α-smooth muscle actin (α-SMA), collagen type Ⅰ (Col Ⅰ), and collagen type Ⅲ (Col Ⅲ)] were assessed. A co-culture system of THP-1 cells (M1 macrophages) and human hepatic stellate cells (LX-2) was established. The cell experiment was designed with blank control (LX-2 alone), model (LX-2 + M1 macrophages), and low-, medium-, and high-dose SNS (co-culture with 5%, 10%, or 20% SNS-containing serum, respectively) groups. Cell viability, inflammatory cytokines, and macrophage phenotype were examined. Human primary hepatic Kupffer cells were allocated into blank control, M1 (LPS 100 μg·L-1+IFN-γ 20 μg·L-1), M2 (IL-4 20 μg·L-1+IL-13 20 μg·L-1), M1+M2, M1+SNS (supplemented with 10% SNS-containing serum for 2 h after culture under M1 conditions for 24 h), M2+SNS (supplemented with 10% SNS-containing serum for 2 h after culture under M2 conditions for 24 h), and M1+M2+SNS groups (supplemented with 10% SNS-containing serum for 2 h after culture under M1+M2 conditions for 24 h), and the expression of nuclear factor-κB (NF-κB) p65 and signal transducer and activator of transcription 3 (STAT3) at protein and mRNA levels was determined. ResultsCompared with the blank group, the model group exhibited increased serum levels of ALT, AST, ALP, PCⅢ, LN, HA, IL-6, and TNF-α, upregulated protein and mRNA levels of α-SMA, Col Ⅰ, and Col Ⅲ in the liver tissue (P<0.05, P<0.01), and decreased IL-10 level and STAT3 mRNA level (P<0.05, P<0.01), accompanied by marked collagen deposition and inflammatory infiltration in the liver. Compared with the model group, all doses of Sini San reversed these alterations (P<0.05, P<0.01), with the high-dose group showing the most pronounced effects. Cell experiments demonstrated that, compared with the blank control group, the model group had elevated levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) and upregulated protein and mRNA levels of M1 markers [cluster of differentiation 86 (CD86, inducible nitric oxide synthase (iNOS), and monocyte chemoattractant protein-1 (MCP-1)] (P<0.01), along with declined level of IL-10 and downregulated expression of M2 markers [(CD163, CD206, and arginase-1 (Arg-1)] (P<0.05,P<0.01). Compared with the model group, treatment with Sini San-containing serum at various concentrations lowered the levels of pro-inflammatory cytokines and expression of M1 markers (P<0.05, P<0.01), while increasing the IL-10 level and M2 marker expression (P<0.05, P<0.01). Additionally, Sini San downregulated the mRNA level of NF-κB and upregulated the mRNA level of STAT (P<0.05, P<0.01). In the experiment with human primary Kupffer cells, compared with the blank group, the M1 group showed increased NF-κB p65 expression (P<0.01) and decreased STAT3 expression (P<0.05), whereas the M2 group exhibited increased STAT3 expression (P<0.01). Compared with the respective model groups, Sini San-containing serum reversed the M1-induced overexpression of NF-κB p65 (P<0.05, P<0.01) and further enhanced the M2-induced STAT3 expression (P<0.05, P<0.01). ConclusionSini San can inhibit the NF-κB p65/STAT3 signaling pathway and repolarize intrahepatic Kupffer cells from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype to attenuate inflammation and suppress hepatic stellate cell activation and collagen deposition, thereby exerting anti-fibrotic effect.

Objective:To investigate the epidemiological characteristics and morbidity trends of hypertensive disorders of pregnancy (HDP) in Shenzhen, China.Methods:This study was a cross-sectional study. Data were based on the Shenzhen Birth Cohort. Pregnant women who gave birth from January 1, 2018 to March 31, 2023 were included. Incidence and change trends of HDP and its different pathological types were analyzed. The enrolled pregnant women were divided into the HDP group and the non-HDP group according to whether HDP occurred. General clinical data and pregnancy outcomes were collected from both groups. The incidence of adverse pregnancy outcomes among pregnant women with different pathological types of HDP was analyzed, and subgroup analyses were performed based on age and body mass index (BMI).Results:A total of 90 117 pregnant women were enrolled, aged (31.6±4.4) years. There were 4 117 cases in the HDP group and 86 000 in the non-HDP group. The overall incidence of HDP in the whole study population was 4.57% (4 117/90 117). From 2018—2023, the incidence of HDP in Shenzhen showed an increasing trend year by year, from 2.88% (523/18 155) to 7.04% (271/3 851). Specifically, the incidence of gestational hypertension increased from 0.93% (168/18 155) to 3.09% (119/3 851), the incidence of preeclampsia-eclampsia increased from 1.78% (323/18 155) to 3.17% (122/3 851), the incidence of chronic hypertension increased from 0.01% (1/18 155) to 0.42% (16/3 851), and the incidence of chronic hypertension with superimposed preeclampsia increased from 0.17% (31/18 155) to 0.36% (14/3 851). The age ((32.8±4.8) years vs. (31.5±4.3) years, P<0.05) and BMI in the first trimester ((23.37±3.77) kg/m 2 vs. (21.35±2.91) kg/m 2, P<0.05) of HDP group were higher than those of the non-HDP group. Subgroup analysis showed that the incidence of HDP in pregnant women aged≥50.0 years was the highest in all age subgroups (42.86% (6/14)). The incidence of HDP in pregnant women with BMI≥30.0 kg/m 2 in the first trimester was the highest among all BMI subgroups (20.44% (241/1 179)). The proportions of preterm birth, gestational diabetes, fetal growth restriction, small for gestational age, placental abruption, and late abortion in HDP group were 30.82% (1 269/4 117), 30.46% (1 254/4 117), 6.80% (280/4 117), 4.86% (200/4 117), 3.59% (148/4 117), and 0.80% (33/4 117), respectively. Conclusions:The incidence of HDP among pregnant women has been increased year by year in Shenzhen, China. With the increase in age and BMI during early pregnancy, the incidence of HDP showed an overall upward trend.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective To observe the value of multi-sequence magnetic resonance imaging(MRI)radiomics in predicting the efficacy of concurrent chemoradiotherapy(CCRT)in locally advanced cervical squamous cell carcinoma(CSCC)patients.Methods Clinical data of 100 CSCC patients underwent CCRT treatment were selected.In order to better validate the performance of the model,patients were randomly divided into the training set(70 cases)and the validation set(30 cases)in a 7∶3 ratio.According to the efficacy criteria for solid tumors,patients were divided into the complete response(CR)group(n=16)and the partial response(PR)group(n=14).Examination images of cross-sectional DWI,T2WI and enhanced T1WI were collected from all patients before treatment.ITK-SNAP software package combined with three sequences were used to outline ROI,and the open source software PyRadiomics was used to extract image omics features.For MRI omics features,the minimum redundancy maximum correlation(mRMR)algorithm was used to analyze and screen out the first 30 main features,and then the minimum absolute contraction and selection method(Lasso)based on 10-fold cross-validation was used to reduce dimensionality to screen the non-zero coefficient features.According to the weighting coefficient of Lasso-Logistic regression model in the training set,patient omics labels were calculated.Logistic regression analysis was used to construct a prediction model based on DWI,T2WI and T1WI sequence prediction models and multiple sequenomics labels.Receiver operating characteristic(ROC)curves evaluated the predictive value of each omics model for CCRT treatment in patients with locally advanced CSCC.Results There were 38 cases in the CR group and 32 cases in the PR group in the training set.There were 16 cases in the CR group and 14 cases in the PR group in the validation set.There were no significant differences in patient age,FIGO stage,differentiation degree,maximum lesion diameter and menstrual status between the CR group and the PR group in the training and validation sets.A total of 851 imaging features were extracted from the ROI target area.After the first 30 features were retained by mRMR algorithm,3 CR-related features were selected from the 851 imaging omics features of each individual sequence by Lasso algorithm and 10-fold cross-validation.Eight CR related features were selected from 2 553 features after the combination of the three sequences.ROC curve results showed that in the training set and validation set,the AUC of multiple sequences combined to predict the therapeutic effect of CCRT in patients with locally advanced CSCC was 0.971 and 0.946,respectively,which was higher than that of T1WI,T2WI and DWI single sequence prediction(training set Z=2.683,2.046,2.817,P<0.05;verification set Z=2.075,2.117,2.005,P<0.05).Conclusion The multi sequence MRI radiomics model has high predictive value for the efficacy of CCRT treatment in locally advanced CSCC patients.
