OBJECTIVE To investigate the application status of prescription pre-review systems in healthcare institutions of Yunnan province， evaluate their system functions and management capabilities， and provide a practical basis for promoting rational drug use. METHODS A questionnaire survey was conducted among public healthcare institutions at or above the secondary level in Yunnan province to investigate the deployment status of the systems. A capability maturity assessment framework was constructed， encompassing 6 dimensions and 39 indicators， including real-time prescription review， prescription correlation review， rule setting， evidence-based information support， prescription authority management， and system operation management. This framework was then used to evaluate the institutions that had implemented the pre-review systems. RESULTS A total of 100 valid questionnaires were collected， with 37 institutions having adopted prescription pre-review systems， mainly tertiary hospitals. The system predominantly adopted a modular architecture and was embedded into the hospital information system through application programming interfaces and middleware， providing certain capabilities for real-time prescription risk identification. Evaluation results indicated that basic functions such as reviewing indications， contraindications， and drug compatibility performed well， while deficiencies remained in functions related to parenteral nutrition prescription， review of drug dosage for specific diseases， individual patient characteristic recognition， and rule setting. Moreover， the construction of review centers and establishment of management systems were also not well-developed. CONCLUSIONS The overall application rate of prescription pre-review systems in Yunnan province remains low. System functions and management mechanisms require further improvement. It is recommended to enhance information infrastructure in lower-level institutions and explore regionally unified review models to promote standardized and intelligent development of prescription review practices.

Acute kidney injury (AKI) is one of the most common and severe nephropathy syndromes in clinical practice and also one of the most common serious complications after organ transplantation, with high incidence and fatality. Iron is an essential trace element in the body. Ferroptosis is a form of programmed cell death induced by the accumulation of iron-mediated lipid peroxidation, and its occurrence is closely related to iron metabolism, lipid metabolism, amino acid metabolism and multiple signaling pathways. Recent studies have shown that ferroptosis plays a key role in the occurrence and development of AKI and provides therapeutic targets for AKI. This article summarizes the regulatory mechanism of ferroptosis and its role in AKI, as well as the compounds that play an important role in the prevention and treatment of AKI by inhibiting ferroptosis, providing new ideas for the future treatment and research of AKI.

Neoadjuvant therapy has become the standard treatment for locally advanced resectable esophageal cancer, significantly improving long-term survival compared to surgery alone. Neoadjuvant therapy has evolved to include various strategies, such as concurrent chemoradiotherapy, chemotherapy, immunotherapy, or targeted combination therapy. This enriches clinical treatment options and provides a more personalized and scientific treatment approach for patients. This article aims to comprehensively summarize current academic research hot topics, review the rationale and evaluation measures of neoadjuvant therapy, discuss challenges in restaging methods after neoadjuvant therapy, and identify the advantages and disadvantages of various neoadjuvant therapeutic strategies.

Objective:To evaluate the clinical outcomes of radical resection and perioperative management strategies in hepatocellular carcinoma (HCC) patients with major vascular invasion and tumor thrombus.Methods:This is a retrospective case series study. From January 2010 to December 2022,clinicopathological data of 387 HCC patients who underwent liver resection at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. In the cohort,there were 326 males (84.2%) and 61 females (15.8%),with an age ( M(IQR)) of 54(16) years (range: 16 to 82 years). One hundred and nineteen patients (30.7%) had macrovascular invasion without thrombus and 268 patients(69.3%) had macrovascular thrombus. Categorical variables were presented as frequencies (percentages). Survival rates were calculated using life-table analysis,and Kaplan-Meier curves were employed to depict overall survival(OS) and recurrence-free survival (RFS). Independent prognostic factors were identified by univariate and multivariate Cox regression. Results:Among 387 patients,R0 resection was achieved in 359 cases (92.8%),with R1 or R2 resection in 28 cases (7.2%). Excluding in-hospital deaths,the 354 R0-resected patients had a median OS of 19.8 months, with 1-, 3-, and 5-year OS rates were 63.3%, 35.1%, and 22.4%, respectively; median RFS was 5.6 months,and 1-, 3-, and 5-year RFS was 34.0%,18.0%,and 14.4%, respectively. Patients receiving preoperative therapy showed a median OS of 26.0 months,1-, 3-, and 5-year OS rates were 75.5%, 48.4%, and 32.5%, respectively. There was no significant difference in the OS of patients with or without preoperative therapy ( P>0.05). The median OS time of patients who received postoperative adjuvant therapy was 53.0 months, and the 1-, 3-, and 5-year OS rates were 87.9%, 59.2%, and 34.8%, respectively. The median OS time of patients who did not receive postoperative adjuvant therapy was 13.7 months, and 1-, 3-, and 5-year OS rates were 56.7%, 31.7%, and 22.4%, respectively ( P<0.01). The median RFS of patients who received postoperative adjuvant therapy was 11.6 months, and the 1-, 3-, and 5-year RFS rates were 49.6%, 29.8%, and 26.8%, respectively. The median RFS of patients who did not receive postoperative adjuvant therapy was 4.2 months, and the 1-,3-,and 5-year RFS rates were 29.2%, 16.1%, and 12.5%, respectively ( P<0.01). Multivariate analysis identified that maximum tumor diameter,postoperative adjuvant therapy,and treatment after recurrence were the independent predictors of the OS of patients with major vascular invasion and tumor thrombus (all P<0.05),while age,surgical approach,and postoperative adjuvant therapy independently influenced the RFS of patients with major vascular invasion and tumor thrombus(all P<0.05). Conclusions:HCC patients with vascular invasion/thrombus could benefit from surgery-based multimodal therapy after careful evaluation. Postoperative adjuvant therapy significantly reduces recurrence and prolongs patients′ survival.

Objective:To investigate the surgical treatment effect and prognostic factors of hilar cholangiocarcinoma.Methods:This is an ambispective cohort study. From August 2005 to December 2022,data of 510 patients who diagnosed with hilar cholangiocarcinoma and underwent surgical resection at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University were retrospectively collected. In the cohort,there were 324 males and 186 females,with an age of ( M (IQR)) 63(13)years (range:25 to 85 years). The liver function at admission was Child-Pugh A (343 cases,67.3%) and Child-Pugh B (167 cases,32.7%). Three hundred and seventy-two(72.9%) patients had jaundice symptoms and the median total bilirubin was 126.3(197.6) μmol/L(range: 5.4 to 722.8 μmol/L) at admission. Two hundred and fourty-seven cases (48.4%) were treated with percutaneous transhepatic cholangial drainage or endoscopic nasobiliary drainage before operation. The median bilirubin level in the drainage group decreased from 186.4 μmol/L to 85.5 μmol/L before operation. Multivariate Logistic regression was used to identify the influencing factors for R0 resection,and Cox regression was used to construct multivariate prediction models for overall survival(OS) and disease-free survival(DFS). Results:Among 510 patients who underwent surgical resection,Bismuth-Corlett type Ⅲ-Ⅳ patients accounted for 71.8%,among which 86.1% (315/366) underwent hemi-hepatectomy,while 81.9% (118/144) underwent extrahepatic biliary duct resection alone in Bismuch-Corlett type Ⅰ-Ⅱ patients. The median OS time was 22.8 months, and the OS rates at 1-,3-,5-and 10-year were 72.2%,35.6%,24.8% and 11.0%,respectively. The median DFS time was 15.2 months,and the DFS rates was 66.0%,32.4%,20.9% and 11.0%,respectively. The R0 resection rate was 64.5% (329/510), and the OS rates of patients with R0 resection at 1-,3-,5-and 10-year were 82.5%, 48.6%, 34.4%, 15.2%,respectively. The morbidity of Clavien-Dindo grade Ⅲ-Ⅴ complications was 26.1%(133/510) and the 30-day mortality was 4.3% (22/510). Multivariate Logistic regression indicated that Bismuth-Corlett type Ⅰ-Ⅲ ( P=0.009), hemi-hepatectomy and extended resection ( P=0.001),T1 and T2 patients without vascular invasion (T2 vs. T1: OR=1.43 (0.61-3.35), P=0.413;T3 vs. T1: OR=2.57 (1.03-6.41), P=0.010;T4 vs. T1, OR=3.77 (1.37-10.38), P<0.01) were more likely to obtain R0 resection. Preoperative bilirubin,Child-Pugh grade,tumor size,surgical margin,T stage,N stage,nerve infiltration and Edmondson grade were independent prognostic factors for OS and DFS of hilar cholangiocarcinoma patients without distant metastasis. Conclusions:Radical surgical resection is necessary to prolong the long-term survival of hilar cholangiocarcinoma patients. Hemi-hepatectomy and extended resection,regional lymph node dissection and combined vascular resection if necessary,can improve R0 resection rate.
