With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.

OBJECTIVE:
To clarify the role of concentrated growth factors (CGF) in the treatment of periodontal cement defects using calcium phosphate cement (CPC) with self-curing properties.
METHODS:
Thirty-six intrabony defects were randomly divided into two groups. The experimental group received CGF+CPC treatment (n=18), while the control group received CPC treatment alone (n=18). The probing depth, clinical attachment loss, and hard tissue filling as measured by cone beam CT (CBCT) were evaluated at baseline and 1 year postoperatively in both groups, and the levels of major growth factors in CGF and serum were compared [platelet-derived growth factor-BB (PDGF-BB), transforming growth factor-β1 (TGF-β1), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF)].
RESULTS:
At baseline, there were no statistically significant differences in probing depth, clinical attachment loss and CBCT measurements between the two groups (P>0.05). At 1 year postoperatively, significant improvements were observed in parameters mentioned above in both groups (P < 0.05). The CGF+CPC group seemed more effective compared with the CPC group in reduction of probing depth [(4.5±1.3) mm vs. (3.2±1.1) mm] and clinical attachment gain [(3.8±0.9) mm vs. (2.0±0.5) mm, P < 0.05]. Compared with the group treated with CPC alone, the hard tissue filling degree shown by CBCT in the CGF+CPC group was significantly increased [the reduction of the depth of the intrabony defects was (3.9±1.2) mm vs. (2.1±0.7) mm, respectively, P < 0.01]. At 1 year post-operatively, the volume of the intrabony defects shown by CBCT in the CGF+CPC group was reduced by (0.031 8±0.004 1) mL, which was significantly more than that in the CPC group [(0.019 7±0.001 2) mL, P < 0.05]. In addition, the concentration of the main growth factors (PDGF-BB, TGF-β1, IGF-1, and VEGF) in CGF were higher than those in serum (P < 0.001).
CONCLUSION
After 1 year of follow-up, the results of the present study indicated that CGF could significantly improve the clinical and radiological effects of CPC on the treatment of periodontal intrabony defects.

Wastewater-based epidemiology has emerged as a transformative surveillance tool for estimating substance consumption and monitoring disease prevalence, particularly during the COVID-19 pandemic. It enables the population-level monitoring of illicit drug use, pathogen prevalence, and environmental pollutant exposure. In this perspective, we summarize the key challenges specific to the Chinese context: (1) Sampling inconsistencies, necessitating standardized 24-hour composite protocols with high-frequency autosamplers (≤ 15 min/event) to improve the representativeness of samples; (2) Biomarker validation, requiring rigorous assessment of excretion profiles and in-sewer stability; (3) Analytical method disparities, demanding inter-laboratory proficiency testing and the development of automated pretreatment instruments; (4) Catchment population dynamics, reducing estimation uncertainties through mobile phone data, flow-based models, or hydrochemical parameters; and (5) Ethical and data management concerns, including privacy risks for small communities, mitigated through data de-identification and tiered reporting platforms. To address these challenges, we propose an integrated framework that features adaptive sampling networks, multi-scale wastewater sample banks, biomarker databases with multidimensional metadata, and intelligent data dashboards. In summary, wastewater-based epidemiology offers unparalleled scalability for equitable health surveillance and can improve the health of the entire population by providing timely and objective information to guide the development of targeted policies.

Background::Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.Methods::Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.Results::A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43–0.68; P <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04–13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65–3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38–1.53; P <0.001). Conclusions::In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration::ClinicalTrials.gov, NCT02309398.

Objective:To explore the role of mechanical hemodynamic support (MHS) in mapping and catheter ablation of patients with hemodynamically unstable ventricular tachycardia (VT), report single-center experience in a cohort of consecutive patients receiving VT ablation during MHS therapy, and provide evidence-based medical evidence for clinical practice.Methods:This was a retrospective cohort study. Patients with hemodynamically unstable VT who underwent catheter ablation with MHS at Beijing Anzhen Hospital, Capital Medical University between August 2021 and December 2023 were included. Patients were divided into rescue group and preventive group according to the purpose of treatment. Their demographic data, periprocedural details, and clinical outcomes were collected and analyzed.Results:A total of 15 patients with hemodynamically unstable VT were included (8 patients in the rescue group and 7 patients in the preventive group). The acute procedure was successful in all patients. One patient in the rescue group had surgical left ventricular assist device (LVAD) implantation, remaining 14 patients received extracorporeal membrane oxygenation (ECMO) for circulation support. ECMO decannulation was performed in 12 patients due to clinical and hemodynamic stability, of which 6 patients were decannulation immediately after surgery and the remaining patients were decannulation at 2.0 (2.5) d after surgery. Two patients in the rescue group died during the index admission due to refractory heart failure and cerebral hemorrhage. During a median follow-up of 30 d (1 d to 12 months), one patient with LVAD had one episode of ventricular fibrillation at 6 months after discharge, and no further episodes of ventricular fibrillation and/or VT occurred after treatment with antiarrhythmic drugs. No malignant ventricular arrhythmia occurred in the remaining 12 patients who were followed up.Conclusions:MHS contributes to the successful completion of mapping and catheter ablation in patients with hemodynamically unstable VT, providing desirable hemodynamic status for emergency and elective conditions.

Fingertip injuries often involve the loss of skin, soft tissue, and sometimes even phalange, seriously affecting the patient's hand function and appearance. Therefore, fingertip reconstruction requires both functional recovery and aesthetics. And how to better restore fingertip defect has become an issue that hand surgeons should continue to explore. In recent years, free flaps have made remarkable progress in the field of fingertip repair, and free flaps such as radial artery superficial palmar branch free flap, free thenar flap and free toe flap provide a variety of effective methods to solve the problem. By referring to the literatures on free flap in fingertip repair, this paper summarises the application status and research progress of free flap in fingertip defect reconstruction, providing a reference for personalised treatment of patients with fingertip defect.

In order to optimize the management mode of drug dispensing in inpatient pharmacy, in April 2023, a tertiary hospital constructed and initiated the whole-process intelligent drug dispensing mode in inpatient pharmacy. By jointly applying hospital information system, pre-approval system, paperless dispensing traceability system, and intelligent distribution system, a standardized business process of " pharmacist confirms orders → medication retrieval/verification/packaging → logistics distribution → nurse verification/dispensing" had been established, achieving visibility, controllability, and traceability of the entire drug dispensing process, ensuring drug safety of wards. Before the implementation of this mode (June 2022 to January 2023), the average number of dispensing orders per month in the hospital′s inpatient pharmacy was 8 498, with an error rate of 3.23% and an average completion time of 15.50 min per order; After implementation (June 2023 to January 2024), the average number of orders per month was 10 099, with an error rate reduced to 0.63%, and the completion time for each order was shortened to 10.10 min. The application of the whole-process intelligent drug dispensing mode had reduced dispensing error rates, and improved work efficiency, which could provide references for other public hospitals to promote intelligent drug dispensing.

In recent years,interest in exploring the potential of Blinatumomab for treatment of B-cell acute lymphoblastic leukemia(B-ALL)at earlier stages has grown.This is because Blinatumomab has shown promising results in the management of refractory/relapsed(R/R)B-ALL and minimal residual disease(MRD).Blinatumomab has shown comparable efficacy to that of conventional chemotherapy as an altern-ative to consolidation or intensive chemotherapy in pediatric B-ALL patients.Moreover,its use as consolidation therapy or in combination with chemotherapy/targeted therapy,especially in combination with third-generation tyrosine kinase inhibitors(TKIs),shows significant promise for improving prognosis for adult B-ALL patients.This may potentially reduce reliance on allogeneic hematopoietic stem cell trans-plantation(allo-HSCT)in Philadelphia chromosome-positive(Ph+)B-ALL patients.Moreover,Blinatumomab is safer,gentler,and more effect-ive than chemotherapy for older adult patients.Effective therapy options are not yet available for infants with KMT2A rearrangement B-ALL;however,preliminary research indicates that Blinatumomab may offer a breakthrough for this subgroup.In this article,we review progress in investigations of Blinatumomab use in newly diagnosed B-ALL patients.

Objective:To investigate the genetic, clinical, and post-treatment characteristics of patients with glycogen storage disease type Ⅲ (GSD Ⅲ).Methods:A retrospective cohort analysis was performed on the genetic and clinical data of 26 cases with GSD Ⅲ who visited the Children's Hospital affiliated with Fudan University from June 2017 to December 2023. The patients were divided into non-missense variation and missense variation groups according to the types of mutation in the AGL gene.The correlation between genotype and phenotype was analyzed. All patients were treated with uncooked cornstarch after diagnosis. The changes before and after treatment were compared in patients who underwent more than twelve months of follow-up. A P value of <0.05 was used to denote statistical significance. Results:Among the 26 cases enrolled, 13 were female and 13 were male, and the median age of diagnosis was 28 (6 to 134) months. A total of thirty-five different types of AGL gene variation were detected, with c.1735+1G>T (9/52, 17.3%) as the hotspot variation. The common clinical manifestations were elevated aminotransferases (26/26, 100%), hepatomegaly (25/26, 96.2%), fasting hypoglycemia (25/26, 96.2%), hyperketonemia (16/18, 88.9%), hypertriglyceridemia (TG) (20/26, 76.9%), elevated CK (16/25, 64.0%), and an abnormal electrocardiogram (12/16, 75.0%). Four cases (15.4%) had symptoms of myopathy at diagnosis. Liver biopsy was performed in eighteen cases, among whom 83.3% (15/18) had liver fibrosis≥S2. The number of cases with elevated levels of CK ( P=0.031) and ALT ( P=0.038)was pronounced in the non-missense variation group compared to that in the missense variation group. There were no statistically significant differences in age, height, liver size, degree of fibrosis, fasting blood glucose (Glu) and TG ( P>0.05). The median follow-up time of 14 cases was 40.5 (20-73) months, with improvement in body stature, reduced liver size, decreased ALT and TG, and improved Glu. However, four (28.6%) cases had new myopathy symptoms with raised CK ( P<0.05) and with advancing age, increased ALT diminished while CK level elevated ( P<0.05). Conclusions:The common clinical manifestations at the early stage of the GSD Ⅲdiagnosis are elevated aminotransferases, hepatomegaly, fasting hypoglycemia, hyperketonemia, high triglycerides, elevated CK, and fibrotic liver in China. Myopathy symptoms may arise following uncooked cornstarch treatment; however, there is significant improvement in height, liver-related, and metabolic parameters.
