OBJECTIVE To introduce the development of an intelligent prescription review decision-support system for anti-tumor drugs and assess its clinical application outcomes. METHODS Relevant data sources， including national and local pharmaceutical administration policies， clinical practice guidelines/consensus， hospital information systems data， and genetic testing results， were integrated. Adhering to the principles of structure， standardization and dynamic updating， a knowledge base covering chemotherapeutic， targeted and immunotherapeutic agents was constructed using a dual-dimensional modeling approach that combined “drug attributes” and “clinical contexts”. This knowledge base was then embedded into the hospital’s electronic medical order system to establish the prescription review decision-support system. The application and performance of the system were evaluated at Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. RESULTS A knowledge base containing 18 318 prescription review rules for anti-tumor drugs was constructed， and a closed-loop prescription review system was successfully established， encompassing pre-prescription real-time intervention， in-process interactive review， and post-prescription evaluation and analysis. From 2021 to 2024， the system generated a total of 57 879 alerts for prescriptions of five typical categories of anti-tumor drugs. For platinum-containing prescriptions， 22 577 alerts were generated， with Cisplatin for injection （lyophilized） being the most frequently alerted drug （13 445 alerts）， and “ototoxicity risk due to combined use” alerts remained high （7 682 alerts）. For methotrexate-containing prescriptions， 3 721 alerts were recorded， primarily related to “precaution-related issues” （76.4%， 2 843/3 721）. For doxorubicin-containing prescriptions， 17 301 alerts were triggered， primarily related to “dosage and administration” （14 315 alerts）. For human epidermal growth factor receptor 2-targeted agents-containing prescriptions， 1 007 alerts were issued， mostly related to “reimbursement restrictions” （956 alerts）. For programmed death-1/programmed death-ligand 1 inhibitors-containing prescriptions， the alerts increased year by year， totaling 13 273 alerts， primarily related to “inappropriate indication” （9 118 alerts）. Over the 4 years， the physician response rates to system alerts were 21.4%， 27.1%， 33.5% and 51.6%， respectively. CONCLUSIONS An intelligent decision-support system for anti-tumor drug prescription review， encompassing a closed-loop process of “real-time pre-event intervention， interactive in-event prescription review， post-event evaluation and analysis”， has been successfully constructed and implemented throughout the entire workflow. There is a discernible trend in this hospital， where the focus on monitoring anti-tumor drugs is shifting towards immunotherapy drugs. Additionally， the acceptance rate of physicians regarding prescription review opinions has been steadily increasing year by year.

Background Gestational weight gain is closely related to maternal and infant health outcomes. Pregnant women are simultaneously exposed to four metals—lithium (Li), vanadium (V), uranium (U), and bismuth (Bi)—through inhalation of fine particulate matter and consumption of contaminated food and water. Existing studies suggest that exposure to these metals may be associated with gestational weight gain. However, no study has yet explored the complex relationships between exposure to mixtures of these four metals and weight gain at different stages of pregnancy. Objective To investigate the associations between mixed exposure to Li, V, U, and Bi in early pregnancy and the average weekly gestational weight gain during both early pregnancy and mid-to-late pregnancy. Methods This prospective study recruited eligible women in early pregnancy from an obstetrics clinic of a tertiary hospital in Jinan, China, between September 2021 and July 2023. Pre-pregnancy weight, current weight (at 11⁺⁰ to 13⁺⁶ weeks of gestation), and spot urine samples (≥5.0 mL) were collected at enrollment. Urinary concentrations of Li, V, Bi, and U were determined using inductively coupled plasma mass spectrometry. Participants were followed up in late pregnancy (≥28 weeks of gestation) to collect information on physical activity via questionnaire; weight measurements at the last antenatal visit (35⁺⁰ to 37⁺⁶ weeks of gestation) were obtained from the hospital information system. After adjusting for covariates, multiple linear regression and generalized additive models were used to assess the associations of individual metals with weekly weight gain in early pregnancy and in mid-to-late pregnancy. Bayesian kernel machine regression (BKMR) and quantile-based g-computation (Qgcomp) were applied to evaluate the joint effects of the metal mixture exposure on weekly weight gain at the two gestational stages. Results A total of 313 pregnant women were included. The geometric means of urinary Li, V, U, and Bi concentrations were 37.07, 0.20, 0.06, and 0.04 μg·L⁻¹, respectively; after creatinine adjustment, the corresponding values were 46.82, 0.25, 0.07, and 0.05 μg·g⁻¹ (Cr). The mean weekly gestational weight gain was (0.19±0.25) kg in early pregnancy and (0.53 ± 0.18) kg in mid-to-late pregnancy. Both multiple linear regression and generalized additive models showed that urinary V concentration was positively associated with average weekly gestational weight gain in early pregnancy, while no significant associations were found for other metals or for gestational weight gain in mid-to-late pregnancy. In the BKMR model with early-pregnancy weight gain as the outcome, V had the strongest association [posterior inclusion probability (PIP)=0.773]. When other metals were fixed at their medians, V showed a positive non-linear association with the outcome. A significant single-metal effect of V and its interaction with Li were observed. Compared with the 50th percentile of the metal mixture, the average weekly weight gain in early pregnancy increased by 0.016 (95%CI: 0.003, 0.029) and 0.018 (95%CI: 0.001, 0.036) at the 60th and 65th percentiles, respectively; conversely, at the 25th percentile, it decreased by 0.026 (95%CI: 0.002, 0.050). Overall, the joint effect of the metal mixture on early- pregnancy weight gain showed an upward trend. In the BKMR model for mid-to-late pregnancy gestational weight gain, all PIPs were<0.5, and no significant single-metal effects, interactions, or joint effects were identified. Qgcomp results confirmed a positive association between the metal mixture and early-pregnancy weight gain (b=0.031, 95%CI: 0.010, 0.051; P<0.01), with V contributing the highest positive weight (0.71). No significant association was found for weight gain in mid-to-late pregnancy (b=0.007, P=0.339). Conclusion Higher levels of co-exposure to the Li, V, Bi, and U metal mixture during early pregnancy may be associated with increased average weekly weight gain in early pregnancy. Among these metals, V exhibits a predominant role and appears to interact with Li. No association is observed between early-pregnancy metal mixture exposure and average weekly gestational weight gain in mid-to-late pregnancy. These findings suggest that monitoring and managing metal exposure during early pregnancy may be crucial for the rational regulation of gestational weight gain.

With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Colchicine, a classic anti-inflammatory agent, has been long used for the prevention and treatment of gouty arthritis and familial Mediterranean fever. Given the pivotal role of inflammation in the development and progression of cardiovascular diseases, the clinical value of colchicine in the secondary prevention of cardiovascular diseases has attracted significant attention. Diabetes mellitus （DM） leads to severe and irreversible vascular complications, and cardiovascular diseases are the leading cause of death in patients with DM. However, existing research indicated heterogeneity in the therapeutic efficacy of colchicine among patients with cardiovascular diseases and those with diabetes complicated by cardiovascular conditions. The heterogeneity manifests as differences in efficacy across various disease stages, patient baseline characteristics, specific cardiovascular event types, endpoint definitions, and treatment regimens. The current domestic and international research findings on colchicine in relation to cardiovascular events—both in patients with CVD and in those with diabetes—were reviewed, with the aim of elucidating the underlying causes of this efficacy heterogeneity and providing evidence-based guidance for identifying patients likely to benefit and optimizing individualized treatment strategies in clinical practice.

Objective:To analyze the clinical features and risk factors for renal injury in children with antineutrophil cytoplasmic antibody (ANCA)-positive IgA vasculitis (IgAV).Methods:A case-control study was conducted. Seventy-two ANCA-positive IgAV children hospitalized at the Children′s Hospital of Chongqing Medical University from January 2017 to October 2022 were enrolled as the ANCA-positive group. Propensity score matching (1∶4) using the nearest neighbor was performed with age and gender as covariate, and 288 cases ANCA-negative IgAV children were included as the ANCA-negative group. Patients with renal injury were named ANCA-positive IgAV nephritis (IgAVN) group and ANCA-negative IgAVN group, respectively. The ANCA-positive IgAVN group was further divided into myeloperoxidase (MPO) group and proteinase 3 (PR3) group based on the type of ANCA. Clinical data including manifestations, laboratory tests, renal injury, and prognosis were collected. Comparisons between groups were performed using independent sample t-tests, Mann-Whitney U tests, χ2 tests, or Fisher′s exact tests. Kaplan-Meier curves were used to assess differences in the time to renal injury onset, and multivariate logistic regression was performed to identify independent risk factors for renal injury. Results:Among the 72 ANCA-positive IgAV children (41 males, 31 females, age of 7.7 (5.3, 11.2) years), no significant difference in age or gender was observed compared to the ANCA-negative group (both P>0.05). The ANCA-positive group had higher IgM levels, a higher incidence of recurrent rash, and shorter thrombin time (all P<0.05). Among children with renal injury, the ANCA-positive group showed significant differences in the incidence of hematuria, clinical classification, and grade A prognosis compared to the ANCA-negative group (all P<0.05), but no difference was found in the time to renal involvement onest or renal pathology (all P>0.05). The MPO group had higher rates of microscopic hematuria, gross hematuria, acute renal insufficiency, glomerular sclerosis, and grade B prognosis compared to the ANCA-negative IgAVN group (all P<0.05), with a later onset of renal involvement ( P<0.05). Elevated serum creatinine ( OR=1.08, 95% CI 1.03-1.14) and shortened thrombin time ( OR=0.71, 95% CI 0.55-0.92) were independent risk factors for renal injury in ANCA-positive IgAV children (all P<0.05). Conclusions:Children with ANCA-positive IgAV are more likely to experience recurrent rash. MPO-ANCA-positive IgAVN children have higher risks of hematuria, acute kidney injury and glomerular sclerosis, with later-onset but poorer renal prognosis compared to ANCA-negative IgAVN children. Higher serum creatinine levels and shorter thrombin time may be associated with renal injury in children with ANCA-positive IgAV.

Background: The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies. Methods: MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function. Results: Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores. Conclusion Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

Objective To investigate the interaction relationship among symptoms in middle-aged patients during the recovery period of stroke and explore its correlation with rehabilitation confidence,providing a reference for the implementation of precise rehabilitation nursing.Methods A cross-sectional study was conducted,and 365 middle-aged patients in the recovery period of stroke who were hospitalized in 4 tertiary general hospitals in Wuhan from April 20 to August 31,2024 were conveniently selected as the subjects of the investigation.Data were collected using the General Information Questionnaire,Stroke Symptom Experience Scale,and Confidence after Stroke Measure Questionnaire.Symptom network analysis was conducted using R software,and a network structure model of symptoms-rehabilitation confidence was constructed;meanwhile,the stability of the network structure was evaluated.Results Finally,350 middle-aged stroke patients in the recovery period were included.The most common symptom was"limb weakness"(81.1％).Symptom network analysis showed that"limited limb movement"was the core symptom(rs=1.118).The symptoms strongly associated with recovery confidence were"limited physical movement","annoyance at not being able to do what you want to do"and"slow reaction times".Stability tests suggest that the model results are all good.Conclusion Symptoms of middle-aged patients in the recovery period after stroke are interrelated,and the mechanisms by which different symptoms affect rehabilitation confidence are also different.It is recommended that healthcare professionals prioritize interventions based on core symptoms and inter-symptom relationships in order to accurately enhance patient outcomes and improve recovery outcomes.

Objective To explore the genetic test results after confirmation and analyze misdiagnoses of prenatal ultrasound of fetal hypospadias.Methods Totally 206 fetuses with prenatal ultrasound suspected hypospadias were retrospectively enrolled,and the outcomes were followed up.For confirmed cases of hypospadias,prenatal ultrasound showed or did not show other abnormalities,with or without chromosomal and genetic abnormalities were collected,while maternal age≥35 years and the presence of other abnormalities detected by prenatal ultrasound related to the risk of chromosomal or genetic abnormalities were conducted.Results Hypospadias was confirmed postpartum in 159 cases,yielding a positive predictive value of 77.18％ (159/206)for prenatal ultrasound.The common prenatal ultrasound manifestations of hypospadias included blunt tip,small penis,ventral curvature and tulip sign.Associated anomalies frequently observed on prenatal ultrasound included cryptorchidism,ventricular septal defect and fetal growth restriction.Maternal age≥35 years and presence of additional abnormalities on prenatal ultrasound were both independent predictors of chromosomal or genetic abnormalities in fetuses with hypospadias(both P＜0.05).Isolated small penis with ventral curvature,congenital adrenal hyperplasia or isolated labia minora hypertrophy in female fetus might lead to misdiagnosis of prenatal ultrasound for fetal hypospadias.Conclusion Prenatal ultrasound had relatively high positive predictive value for diagnosing fetal hypospadias.Maternal age≥35 years and presence of other abnormalities on prenatal ultrasound suggested increased risk of chromosomal or genetic abnormalities.

Objectives:To explore the relationship between carboxymethyl lysine (CML) and type 2 diabetes (T2DM) with myopenia, so as to provide some clinical reference for clinical prevention and early intervention of myopenia.Methods:A case-control study was conducted, selecting 142 T2DM patients admitted to the Endocrinology Department of the Affiliated Hospital of North China University of Science and Technology from November 2022 to November 2023. According to the diagnostic criteria of the 2019 consensus of experts on the diagnosis and treatment of sarcopenia, the patients were divided into a case group (T2DM with sarcopenia, 58 cases) and a control group (T2DM without sarcopenia, 84 cases). Collect and compare general information, serological data, and body composition data of two groups of patients. Two independent sample t-test is used for inter group comparison of metric data that conforms to normal distribution; Non parametric tests are used for inter group comparisons of non normally distributed quantitative data; The comparison of count data between groups is conducted using χ2 test. Multivariate logistic regression analysis was used to analyze the relationship between carboxymethyl lysine and type 2 diabetes with myopenia. Draw receiver operating characteristic (ROC) curves and analyze the efficacy of carboxymethyllysine in diagnosing T2DM with muscle atrophy. Results:Univariate analysis showed the BMI ((21.59±3.04) kg/m 2), FINS (4.49 (1.85,9.03) U/L), and FCP ((1.45±0.96) mg/L) levels of the patients in the case group were lower than those in the control group(27.32±3.74) kg/m 2, 6.91 (3.74, 11.99) U/L, (2.64±1.23) mg/L), while age, ((64.67±6.75) years old) of disease duration(12.16±6.69) years, and CML (5.70±2.14 μg/L) were higher than those in the control group ((62.23±7.33) years old, (8.70±8.01) years, (2.38±0.73) μg/L), and the differences were statistically significant (Statistical values were t=9.66, Z=2.86, t=6.46, t=2.02, t=2.70, t=13.17; P values were <0.001, 0.004, <0.001, 0.046, 0.008, <0.001). Multifactorial binary logistic regression analysis showed that CML ( OR(95%CI):3.242 (1.933-5.437)) and BMI ( OR(95%CI):0.636 (0.505-0.801)) were associated with T2DM combined with sarcopenia (all P<0.001). The results of the ROC curve showed that the area under the curve (AUC) of CML was 0.934, and the corresponding optimal cut-off value was 3.038 μg/L. The diagnostic efficacy of CML for the diagnosis of T2DM combined with myasthenia gravis was high, and the diagnostic results were in good agreement with the actual results. Conclusions:Carboxymethyl lysine is associated with T2DM combined with muscle atrophy. CML has a high diagnostic efficacy in diagnosing T2DM combined with muscle atrophy, and it has certain practical value in diagnosing T2DM combined with muscle atrophy.
