In December 2025， the American Association for the Study of Liver Diseases （AASLD） and the American Society of Transplantation （AST） jointly issued an updated guideline on the evaluation of adult liver transplant candidates. The guideline is organized into four domains， i.e.， referral for liver transplantation， candidate evaluation， contraindications to liver transplantation， and special considerations （e.g.， living donor liver transplantation）， in order to provide a standardized framework for clinical assessment. This new guideline updates the 2013 edition based on the latest evidence-based medical evidence and incorporates discussions on emerging indications for liver transplantation， including intrahepatic cholangiocarcinoma and colorectal liver metastases. This guideline emphasizes that candidate assessment must be individualized， and the assessment process must be transparent and consistent. This article gives an excerpt of the key recommendations in this guideline for readers’ reference.

Objective To address the issue of information silos in inpatient pharmaceutical logistics,and to achieve real-time monitoring of hospital-wide pharmaceutical logistics,thereby reducing labor and time costs.Methods This study utilized the Hospital Information System(HIS)and barcode scanning technology to record and upload pharmaceutical logistics information.A questionnaire survey method was employed to collect data on clinical department satisfaction,and the number of drug circulation consultation calls as research subjects.The study evaluated the inpatient pharmaceutical comprehensive tracking service platform from the number of calls for drug circulation information and clinical department satisfaction.Results The inpatient pharmaceutical full-process tracking service platform allowed pharmacists and clinical departments to grasp pharmaceutical logistics information more.There was a significant decrease in the proportion of calls for drug circulation information to the pharmacy and pharmacy intravenous admixture service before and after the platform's implementation.The proportion of calls for drug circulation information was significantly reduced.Additionally,the satisfaction of clinical departments increased by 40.35％after the platform's implementation,indicating a significant improvement in satisfaction.Conclusion The inpatient pharmaceutical full-process tracking service platform(IPTP)has significantly enhanced the level of pharmaceutical informatization and raised the satisfaction rate of clinical departments.

Objective:To investigate the clinicopathological characteristics and prognostic factors of different histological subtypes of intrahepatic cholangiocarcinoma (ICC).Methods:The retrospective cohort study was conducted. The clincopathological data of 171 patients with ICC who underwent initial curative resection in Peking University People′s Hospital from January 2015 to December 2023 were collected. There were 94 males and 77 females, aged 60(range, 53-68)years. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were expressed as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi‐square test or Fisher exact probability. The Kaplan‐Meier method was used to draw survival curve and calculate survival rates, and the Log-rank test was used for survival analysis. The COX stepwise regression model was used for univariate and multivariate analyses. Results:(1) Comparison of clinicopathological characteristics of different histological subtypes of ICC. Results of postoperative histopathological examination showed that of the 171 ICC patients, there were 76 cases of large duct type ICC and 95 cases of small duct type ICC. There was a significant difference in cases with concomitant intrahepatic biliary stone between patients with different histological subtypes of ICC ( P<0.05), and there were significant differences in cases with concomitant viral hepatitis, cases with CA19-9 >39 U/mL versus CA19-9 ≤39 U/mL, cases with CA19-9 >1 000 U/mL versus CA19-9 >39-1 000 U/mL, tumor gross morphology, and tumor peri-neural invasion between patients with different histological subtypes of ICC ( χ2=8.906, 18.208, 5.689, 43.886, 6.178, P<0.05). (2) Prognostic analysis of different histological subtypes of ICC. Of the 171 patients, 130 cases were followed up for 22(range, 16-43)months, including 63 cases of large duct type ICC and 67 cases of small duct type ICC. The 5-year overall survival rates of the 63 cases of large duct type ICC and 67 cases of small duct type ICC were 12.60% and 43.70%, respectively, showing a significant difference between them ( χ2=5.799, P<0.05). (3) Analysis of prognostic factors for patients undergoing radical resection of ICC. Results of multivariate analysis showed that tumor perineural invasion and lymph node metastasis were independent risk factors affecting overall survival rates of patients undergoing radical resection of ICC ( hazard ratio=0.447, 0.383, 95% confidence interval as 0.259-0.771, 0.225-0.651, P<0.05). Conclusions:There are differences in both clinicopatholo-gical characteristics and prognosis between patients with large duct type ICC and small duct type ICC. Tumor perineural invasion and lymph node metastasis are independent risk factors affecting overall survival rates of patients undergoing radical resection of ICC.
