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.

Pancreatic cancer is a highly malignant digestive system tumor. Due to its rapid progression and difficulty in early diagnosis, patients are often diagnosed at an advanced stage or with metastases. Liver is the most common metastatic site of pancreatic cancer, and its prognosis and treatment are not optimistic. In recent years, with the progress of basic research, the research on the molecular mechanism of liver metastasis in pancreatic cancer has also made great progress. This paper briefly summarize the current progress of molecular mechanism research of liver metastasis in pancreatic cancer.

Objective:To evaluate the relationship between the mechanism by which aucubin improved attention deficit hyperactivity disorder (ADHD) induced by maternal exposure to S-ketamine and GABAergic neurons in the habenular nucleus of offspring mice.Methods:SPF healthy C57BL/6 wild-type pregnant mice were used in this study, and an ADHD model in offspring mice was established by intraperitoneally injecting S-ketamine in the middle and late pregnancy. Twenty-four offspring of pregnant mice exposed to S-ketamine were divided into 2 groups ( n=12 each) at 14 days after birth using a random number table method: ADHD + normal saline group (AN group) and ADHD + aucubin group (AA group). Twenty-four offspring of pregnant mice exposed to normal saline were divided into 2 groups ( n=12 each) at 14 days after birth by a random number table method: control + normal saline group (CN group) and control + aucubin group (CA group). Aucubin 40 mg/kg was intraperitoneally injected once a day for 7 consecutive days in CA group and AA group, and the equal volume of normal saline was given instead in CN group and AN group. At 14 days after birth, the 16-channel microfilament array electrode was placed in the habenular nucleus, and the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was recorded when the mice buried beads in the marble burying test. At 21 days after birth (after the end of peritoneal administration), the impulsive and stereotypical behaviors of offspring mice were evaluated by elevated zero maze and marble burying test, respectively, and then the expression of glutamate decarboxylase 2 (GAD2) in habenular nucleus was detected by the immunofluorescence method. Results:Compared with CN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly increased, the expression of GAD2 was down-regulated, the time spent in the open arm was prolonged, the number of entries into the open arm and the number of buried beads were increased in AN group ( P<0.05), and no statistically significant differences were found in the above indexes in CA group ( P>0.05). Compared with AN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly decreased, the expression of GAD2 was up-regulated, the time spent in the open arm was shortened, and the number of entries into the open arm and the number of buried beads were decreased in AA group ( P<0.05). Conclusions:The mechanism by which aucubin alleviates prenatal S-ketamine exposure-induced ADHD may be related to increasing the number of GABAergic neurons in the habenular nucleus of offspring mice.

To evaluate the effects of abdominal belts in colonoscopy for patients with low body mass index (BMI) (BMI<18.5 kg/m2) or a history of abdominal surgery, a prospective, randomized, single-blind study was conducted on colonoscopy outpatients. Patients with low BMI or a history of abdominal surgery who underwent colonoscopy at the Second Affiliated Hospital of Soochow University from January 2018 to January 2022 were enrolled. The patients were divided into the abdominal belts group and non-abdominal belts group according to whether they used abdominal belts. Differences between the two groups were compared in terms of cecal intubation time, length of colonoscope intubation into the cecum, patient repositioning, abdominal pressure, and degree of abdominal distension. A total of 296 patients (98 low BMI patients and 198 patients with a history of abdominal surgery) were enrolled, 148 in each group. The results showed that cecal intubation time (4.35±1.85 min VS 7.99±3.86 min, t=35.624, P<0.001) and length of colonoscope intubation into the cecum (72.03±10.35 cm VS 86.42±17.71 cm, t=38.442, P<0.001) were lower in the abdominal belts group, compared with those of the non-abdominal belts group. The percentage of patients requiring repositioning [18.9% (28/148) VS 71.6% (106/148), χ2=82.959, P<0.001] and abdominal pressure [6.1% (9/148) VS 52.7% (78/148), χ2=77.504, P<0.001] in the abdominal belts group were significantly lower than those in the non-abdominal belts group. There were significant differences in the degree of abdominal distension during and after colonoscopy ( P<0.001). In conclusion, the use of abdominal belts significantly improves the efficiency and effects of colonoscope intubation in difficult colonoscopy patients with low BMI and a history of abdominal surgery.

Objective:To investigate the surgical situations and perioperative outcome of pancreaticoduodenectomy in Jiangsu Province and the influencing factors for postoperative 90-day mortality.Methods:The retrospective case-control study was conducted. The clinicopathological data of 2 886 patients who underwent pancreaticoduodenectomy in 21 large tertiary hospitals of Jiangsu Quality Control Center for Pancreatic Diseases, including The First Affiliated Hospital of Nanjing Medical University, from March 2021 to December 2022 were collected. There were 1 732 males and 1 154 females, aged 65(57,71)years. Under the framework of the Jiangsu Provincial Pancreatic Disease Quality Control Project, the Jiangsu Quality Control Center for Pancreatic Diseases adopted a multi-center registration research method to establish a provincial electronic database for pancrea-ticoduodenectomy. Observation indicators: (1) clinical characteristics; (2) intraoperative and post-operative conditions; (3) influencing factors for 90-day mortality after pancreaticoduodenectomy. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or constituent ratio, and comparison between groups was conducted using the chi-square test, continuity correction chi-square test and Fisher exact probability. Maximal Youden index method was used to determine the cutoff value of continuous variables. Univariate analysis was performed using the corresponding statistical methods based on data types. Multivariate analysis was performed using the Logistic multiple regression model. Results:(1) Clinical characteristics. Of the 2 886 patients who underwent pancreaticoduodenectomy, there were 1 175 and 1 711 cases in 2021 and 2022, respectively. Of the 21 hospitals, 8 hospitals had an average annual surgical volume of <36 cases for pancreaticoduodenectomy, 10 hospitals had an average annual surgical volume of 36-119 cases, and 3 hospitals had an average annual surgical volume of ≥120 cases. There were 2 584 cases performed pancreaticoduodenectomy in thirteen hospitals with an average annual surgical volume of ≥36 cases, accounting for 89.536%(2 584/2 886)of the total cases. There were 1 357 cases performed pancrea-ticoduodenectomy in three hospitals with an average annual surgical volume of ≥120 cases, accounting for 47.020%(1 357/2 886) of the total cases. (2) Intraoperative and postoperative conditions. Of the 2 886 patients, the surgical approach was open surgery in 2 397 cases, minimally invasive surgery in 488 cases, and it is unknown in 1 case. The pylorus was preserved in 871 cases, not preserved in 1 952 cases, and it is unknown in 63 cases. Combined organ resection was performed in 305 cases (including vascular resection in 209 cases), not combined organ resection in 2 579 cases, and it is unknown in 2 cases. The operation time of 2 885 patients was 290(115)minutes, the volume of intra-operative blood loss of 2 882 patients was 240(250)mL, and the intraoperative blood transfusion rate of 2 880 patients was 27.153%(782/2 880). Of the 2 886 patients, the invasive treatment rate was 11.342%(327/2 883), the unplanned Intensive Care Unit (ICU) treatment rate was 3.087%(89/2 883), the reoperation rate was 1.590%(45/2 830), the duration of postoperative hospital stay was 17(11)days, the hospitalization mortality rate was 0.798%(23/2 882), and the failure rate of rescue data in 2 083 cases with severe complications was 6.529%(19/291). There were 2 477 patients receiving postoperative 90-day follow-up, with the 90-day mortality of 2.705%(67/2477). The total incidence rate of complication in 2 886 patients was 58.997%(1 423/2 412). The incidence rate of severe complication was 13.970%(291/2 083). The comprehensive complication index was 8.7(22.6) in 2 078 patients. (3) Influencing factors for 90-day mortality after pancreaticoduodenectomy. Results of multivariate analysis showed that age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment were independent risk factors for 90-day mortality after pancreaticoduodenectomy ( odds ratio=2.403, 2.609, 16.141, 95% confidence interval as 1.281-4.510, 1.298-5.244, 7.119-36.596, P<0.05). Average annual surgical volume ≥36 cases in the hospital was an independent protective factor for 90-day mortality after pancreaticoduodenectomy ( odds ratio=0.368, 95% confidence interval as 0.168-0.808, P<0.05). Conclusions:Pancreaticoduodenectomy in Jiangsu Province is highly con-centrated in some hospitals, with a high incidence of postoperative complications, and the risk of postoperative 90-day mortality is significant higher than that of hospitallization mortality. Age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment are independent risk factors for 90-day motality after pancreaticoduodenectomy, and average annual surgical volume ≥36 cases in the hospital is an independent protective factor.
