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.

Drug repurposing offers a promising alternative to traditional drug development and significantly reduces costs and timelines by identifying new therapeutic uses for existing drugs. However, the current approaches often rely on limited data sources and simplistic hypotheses, which restrict their ability to capture the multi-faceted nature of biological systems. This study introduces adaptive multi-view learning (AMVL), a novel methodology that integrates chemical-induced transcriptional profiles (CTPs), knowledge graph (KG) embeddings, and large language model (LLM) representations, to enhance drug repurposing predictions. AMVL incorporates an innovative similarity matrix expansion strategy and leverages multi-view learning (MVL), matrix factorization, and ensemble optimization techniques to integrate heterogeneous multi-source data. Comprehensive evaluations on benchmark datasets (Fdataset, Cdataset, and Ydataset) and the large-scale iDrug dataset demonstrate that AMVL outperforms state-of-the-art (SOTA) methods, achieving superior accuracy in predicting drug-disease associations across multiple metrics. Literature-based validation further confirmed the model's predictive capabilities, with seven out of the top ten predictions corroborated by post-2011 evidence. To promote transparency and reproducibility, all data and codes used in this study were open-sourced, providing resources for processing CTPs, KG, and LLM-based similarity calculations, along with the complete AMVL algorithm and benchmarking procedures. By unifying diverse data modalities, AMVL offers a robust and scalable solution for accelerating drug discovery, fostering advancements in translational medicine and integrating multi-omics data. We aim to inspire further innovations in multi-source data integration and support the development of more precise and efficient strategies for advancing drug discovery and translational medicine.
4.Treatment Strategy and Research Progress of Immune Microenvironment for Liver Metastasis of Non-small Cell Lung Cancer
Cancer Research on Prevention and Treatment 2024;51(3):203-209
Liver is the common site for metastasis and spread of non-small cell lung cancer (NSCLC). Lung cancer patients with liver metastasis have poor prognosis, which may be related to liver-specific microenvironment composition. The metastasis of lung cancer to the liver is regulated by various pathophysiological factors, including the liver immune microenvironment, related cells, proteins, signaling molecules, and gene changes. These factors will affect the consistent disease process and subsequent treatment strategies. Immune checkpoint inhibitors (ICIs) have made breakthroughs in treatment of patients with advanced NSCLC. However, NSCLC patients with liver metastasis, a unique population of advanced lung cancer, are characterized by poor immunotherapeutic effect. This paper reviews the related mechanisms of the immune microenvironment in affecting the occurrence and development of liver metastases and summarizes the achievements and prospects of anti-tumor immunotherapy in liver metastases of NSCLC.

Objective:To study the effect of first drainage failure on the prognosis of perihilar cholangiocarcinoma (PHCC).Methods:The clinical data of 68 patients with PHCC undergoing surgery in the Department of Pancreatic and Metabolic Surgery of Nanjing Drum Tower Hospital, Affiliated to the Medical School of Nanjing University, from April 2014 to December 2022 were retrospectively analyzed, including 46 males and 22 females, aged (63±9) (range, 39-80) years old. The patients were divided into two groups based on whether the first drainage was successful: successful group ( n=34) and failed group ( n=34). The patient's age, gender, first drainage, complications and other clinical data were collected. Patients were followed up by outpatient or telephone review. Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival comparison. Results:Compared to the successful group, the drainage time [41(28, 52) d vs. 20(14, 28) d], the drainage tube adjustment rate [32.4%(11/34) vs. 0(0/34)], and the incidence of complications after drainage [88.2% (30/34) vs. 0(0/34)] were all increased in the failed group, with the adjustment rate of drainage position decreased [82.4%(28/34) vs. 100%(34/34)] (all P<0.05). Compared to the successful group, the incidence of abdominal infection was higher [70.6%(24/34) vs. 44.1%(15/34)] in the failed group ( P=0.027). The 5-year cumulative survival rates of the failed group and the successful group were 61.4% and 44.1%, respectively ( P>0.05). Conclusion:Compared to the patients of PHCC with first successful drainage, the risk of abdominal infection is increased when first drainage failed, while the incidence of postoperative complications, in-hospital mortality and long-term survival rate are comparable.

Objective:To investigate whether intestinal rehabilitation therapy (IRT)could optimize the effectiveness of IRT in patients with short bowel syndrome (SBS) caused by acute mesenteric ischemia (AMI) with chronic multivessel lesions.Methods:Clinical data of 18 hospitalized patients diagnosed with AMI leading to SBS and undergoing IRT at the Eastern Theater General Hospital of the People's Liberation Army from Jan 2012 to Oct 2023 was retrospectively analyzed.Result:Following IRT, the revascularization group showed significantly greater increases in ASMI and grip strength compared to the control group [(0.28±0.26) kg/m 2vs. (0.02±0.21) kg/m 2, P=0.033, and (0.97±0.33) kg vs. (0.48±0.34) kg, P=0.007, respectively]. Similarly, the increase in EN intake was significantly higher in the revascularization group compared to the control group [(572.5±93.6) ml/d vs. (375.2±176.3) ml/d, P=0.012], accompanied by a greater improvement in intestinal nitrogen absorption rate [(25.06±14.06)% vs. (13.84±4.62)%, P=0.034] and a more substantial decrease in GSRS scores [(-15.88±3.94) vs. (-6.33±5.13), P=0.030]. Moreover, there were significant differences in the composition of EN formulations between the two groups after IRT ( P=0.046). Additionally, SF-36 scores at discharge were significantly higher in the revascularization group than that in the control group for five indicators including BP, GH, VT, SF, and MH ( P<0.05). Conclusions:For patients with SBS resulting from AMI by chronic multivessel lesions, revascularization therapy may not leading to higher growth in weight and hematological nutritional indicators during IRT, but it is beneficial for improving muscle function, improving EN absorption, increasing the likelihood of PN independence, relieving gastrointestinal symptoms, and enhancing overall quality of life.

OBJECTIVE To explore the role of clinical pharmacists participating in the standardized perioperative nutritional management process for pancreaticoduodenectomy (PD) on improving postoperative recovery in patients. METHODS The clinical data of 100 patients undergoing PD in the Department of Biliary and Pancreatic Surgery, Drum Tower Hospital Affiliated to Nanjing University School of Medicine from November 2019 to February 2021 were analyzed retrospectively. According to the different perioperative nutrition management plans, they were divided into clinical pharmacist intervention group (n=51, clinical pharmacists intervened according to the standardized nutrition management process) and control group (n=49, clinical pharmacists only performed preoperative nutrition evaluation, and clinical physicians took nutrition support according to the patient’s condition). The differences in postoperative recovery index, economic evaluation index, hospitalization length, postoperative complications, and postoperative enteral nutrition support route were compared between 2 groups. RESULTS The time of postoperative diet, the first postoperative ventilation, the first postoperative defecation, and postoperative drainage time of abdominal drain were significantly earlier in the clinical pharmacist intervention group than in the control group (P<0.05); the hospitalization cost, medication cost, nutritional support cost, parenteral nutrition cost, albumin preparation cost, and the length of postoperative hospitalization were significantly lower/shorter in the clinical pharmacist intervention group than in the control group (P<0.05); there was no statistically significant difference in the incidence of postoperative complications between the two groups (P>0.05); there was statistically significant difference in the perioperative enteral nutrition support pathways between two groups (P<0.05). CONCLUSIONS Clinical pharmacists’ participation in perioperative nutritional management for PD can significantly reduce hospitalization costs and nutritional support costs, improve patients’ perioperative nutritional status, and shorten hospital stays. wanglina668@163.com
