Objective:To investigate the evaluation efficacy and predictive prognostic value of alpha-fetoprotein (AFP) response in tyrosine kinase inhibitors (TKIs) in combination with PD-1 inhibitors (α-PD-1) for intermediate-to-advanced hepatocellular carcinoma (HCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 205 patients with intermediate-to-advanced HCC who were admitted to 9 medical centers, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from March 2020 to July 2022 were collected. There were 178 males and 27 females, aged (52±12)years. Based on AFP response at 6-8 weeks after treatment, patients were divided into the AFP response group (AFP level decreased by ≥50% compared to baseline) and the AFP no response group (AFP level decreased by <50% compared to baseline). Observation indicators: (1) AFP response evaluation of anti-tumor efficacy; (2) comparison of patient prognosis; (3) analysis of factors affecting patient prognosis. Measurement data with normal distrubution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range) and M( Q1, Q3). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curve and calculate survival rate, and the Log-Rank test was used for survival analysis. The COX proportional risk model was used for univariate analysis and the COX stepwise regression model was used for multivariate analysis. Results:(1) AFP response evaluation of anti-tumor efficacy. Before treatment, all 205 patients were positive of AFP, with a baseline AFP level of 1 560(219,3 400)μg/L. All 205 patients were treated with TKIs in combination with α-PD-1, and the AFP level was 776(66,2 000)μg/L after 6 to 8 weeks of treatment. Of the 205 patients, 88 cases were classified as AFP response and 117 cases were classified as AFP no response. According to the response evaluation criteria in solid tumors version 1.1, the objective response rate (ORR) and disease control rate (DCR) were 42.05%(37/88) and 94.32%(83/88) in patients of the AFP response group and 16.24% (19/117) and 64.10% (75/117) in patients of the AFP no response group, showing significant differences between them ( χ2=16.846, 25.950, P<0.05). According to the modified response evaluation criteria in solid tumors, the ORR and DCR were 69.32% (61/88) and 94.32% (83/88) in patients of the AFP response group and 33.33% (39/117) and 64.10% (75/117) in patients of the AFP no response group, showing significant differences between them ( χ2=26.030, 25.950, P<0.05). (2) Comparison of patient prognosis. All 205 patients were followed up for 12.4(range, 2.4-34.0)months after treatment. The median progression free survival time and total survival time were 5.5 months and 17.8 months, respectively. The 1-year, 2-year progression free survival rates were 20.8% and 7.2%, and the 1-year, 2-year overall survival rates were 68.7% and 31.5%, respectively. The median progression free survival time, 1-year and 2-year progression free survival rates were 9.7 months, 39.6% and 14.2% in patients of the AFP response group and 3.7 months, 7.8% and 2.0% in patients of the AFP no response group, showing a significant difference in progression free survival between them ( χ2=43.154, P<0.05). The median overall survival time, 1-year and 2-year overall survival rates were not reached, 85.2% and 56.3% in patients of the AFP response group and 14.6 months, 56.3% and 14.5% in patients of the AFP no response group, showing a significant difference in overall survival between them ( χ2=33.899, P<0.05). (3) Analysis of factors affecting patient prognosis. Results of multivariate analysis showed that invasion of large blood vessels, extrahepatic metastasis, combined hepatic artery intervention therapy, and AFP response were independent factors influencing progression free survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1 ( hazard ratio=1.474, 1.584, 0.631, 0.367, 95% confidence interval as 1.069-2.033, 1.159-2.167, 0.446-0.893, 0.261-0.516, P<0.05), and Eastern Cooperative Oncology Group score, invasion of large blood vessels, extrahepatic metastasis, and AFP response were independent factors influencing overall survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1 ( hazard ratio= 1.347, 1.914, 1.673, 0.312, 95% confidence interval as 1.041-1.742, 1.293-2.833, 1.141-2.454, 0.197-0.492, P<0.05). Conclusions:AFP response at 6-8 weeks after treatment can effectively evaluate anti-tumor efficacy of TKIs in combination with α-PD-1 for intermediate-to-advanced HCC. AFP response is the independent factor influencing progression free survival and overall survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

【Objective】 To explore and verify the mechanism of curcumin’s inhibition of the proliferation of renal clear cell carcinoma （RCCC） based on network pharmacology and bioinformatics. 【Methods】 We screened common target genes of RCCC and curcumin from PharmMapper and GeneCards databases. We used TCGA database data analysis to screen out common target genes which not only differentially expressed between RCCC tissue samples and normal tissue samples but also affected prognosis. We also used STRING platform to construct curcumin-RCCC targets interaction network， used R software to perform GO biological process analysis and KEGG pathway enrichment analysis based on the above-mentioned screening target proteins. After curcumin and/or active oxygen inhibitor N-acetyl-L-cysteine （NAC） were incubated in renal cancer 786-O and ACHN cells， CCK8 was used to detect the effects of different concentrations of curcumin on cell proliferation and cell viability. Reactive oxygen detection kit （DCFH-DA） was used to detect the level of intracellular reactive oxygen species， and malondialdehyde （MDA） determination kit （TBA method） to detect intracellular malondialdehyde changes. 【Results】 PharmMapper website and GeneCards database screened out 109 common targets of curcumin and RCCC. TCGA database data analysis screened out 37 differentially expressed genes （DEGs） that might affect the overall survival of patients. The core target proteins of curcumin screened out by protein-protein interaction （PPI） that inhibited the biological behavior of RCCC mainly involved CASP3， EGFR， CHEK1， HSP90AA1， and AR. GO enrichment analysis identified 213 items， mainly including reactive oxygen species metabolic process， response to steroid hormones， fibrinolysis and other biologically active processes. KEGG enrichment analysis identified 24 items， which were mainly related to pyruvate metabolism， glycolysis/gluconeogenesis， FoxO signaling pathway， colorectal cancer， tyrosine metabolism， IL-17 signaling pathway， apoptosis and other signaling pathways. Curcumin reduced the cell viability of 786-O and ACHN in a time- and dose-dependent manner （P<0.05）. After curcumin was incubated with kidney cancer cells， the level of reactive oxygen species and MDA increased significantly （P<0.05）. The addition of NAC reversed the effect of curcumin on the cell viability of 786-O and ACHN cells （P<0.05）. 【Conclusion】 Curcumin may participate in the oxidative stress pathway to inhibit the proliferation of renal cell carcinoma.

【Objective】 To establish a prognostic model of fatty acid metabolism related genes for predicting the prognosis of renal clear cell carcinoma. 【Methods】 The differentially expressed fatty acid metabolism-related genes in renal clear cell carcinoma samples and normal samples in TCGA database were screened by R language software. The Cox proportional hazard regression model was used to select and establish a multigene prognostic model and the prognostic score was calculated. Patients were divided into high-risk group and low-risk group according to the median prognostic score. Kaplan-Meier survival curve was used to analyze the difference in two groups. The clinical pathological factors and prognostic score factors were included in the Cox regression model to analyze the factors affecting the survival of patients with renal clear cell carcinoma. ROC receiver operating curve analysis was used to evaluate the accuracy of the prognostic prediction model. The prognostic model of fatty acid metabolism-related genes and their correlation with clinical factors were analyzed. GSEA enrichment analysis analyzed the differences of gene sets in risk groups. 【Results】 A total of 4 differential genes (CPT1B, HADH, CYP4A11, and ACADSB) were selected to establish a prognostic model for genes related to fatty acid metabolism in renal cell carcinoma. The prognostic risk score (RS) formula is as follows: RS=0.490×CPT1B-0.428×HADH-0.11 × CYP4A11-0.372 × ACADSB. Kaplan-Meier survival analysis confirmed that the overall survival rate of patients with low-risk prognostic score was significantly higher in patients with overall renal clear cell carcinoma, and the difference was statistically significant (P<0.001). Cox regression analysis showed that the prognostic model of genes related to age and fatty acid metabolism is an independent influencing factor for the prognosis of patients with renal clear cell carcinoma (P<0.01). The 5 years’ AUC of the renal clear cell carcinoma ROC curve of the renal cancer fatty acid metabolism related gene model was 0.802. GSEA analysis showed that the difference of 81 gene sets in the low-risk group was statistically significant (P<0.05). 【Conclusion】 The prognostic model of renal cancer fatty acid metabolism-related genes can be used to predict the prognosis of patients with renal clear cell carcinoma, which is conducive to further guide clinical treatment.

Retrovenal ureter is a type of inferior vena cava mutation. Retrovenal ureter with right double inferior vena cava mutation is rare. We reported a case of retrocaval ureteral with right double inferior vena cava variation, right ureteral calculi and hydronephrosis of the right kidney. Peritoneal laparoscopic ureterolithotomy and right posterior vena cava dissection ureteroplasty were performed. Fourteen months after surgery, B-ultrasound of the urinary system was reexamined, and no hydronephrosis was found in the right renal pelvis and ureter.

There were 281 males and 167 females, aged from 22 to 80 years, with a median age of 57 years. Of the 448 patients, 143 with routinely intraoperative LND were divided into LND group and 305 without routinely intraoperative LND were divided into control group, respectively. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups after matching; (2) intraoperative and postoperative situations; (3) follow-up; (4) survival analysis. Patients were followed up by outpatient examination, telephone interview and email to detect survival of patients and tumor recurrence up to October 31, 2018 or death. Follow-up was conducted once every 3 months within postoperative 1-2 years, once every 6 months within postoperative 2-5 years, and once a year after 5 years. The propensity score matching was realized using the nearest neighbor method with 1∶1 ratio. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Kaplan-Meier method was used to calculate survival rates and draw survival curve, and Log-rank test was used to perform survival analysis. Univariate analysis and multivaraiate analysis were conducted using the Log-rank test and COX regression model, respectively. Results: (1) The propensity score matching conditions and comparison of general data between the two groups after matching: 286 of 448 patients had successful matching, including 143 in each group. The number of males and females, cases with hepatitis, cases with grade A and B of Child-Pugh classification, cases with distance from margin to tumor <1 cm and ≥1 cm, cases with highly, moderately, and poorly differentiated tumor, cases with anatomical hepatectomy and nonanatomical hepatectomy before propensity score matching were 77, 66, 33, 96, 47, 70, 73, 105, 38, 79, 64 in the LND group, and 204, 101, 121, 165, 140, 207, 98, 251, 54, 124, 181 in the control group, respectively, showing significant differences in the above indices between the two groups (χ²=7.079, 11.885, 7.098, 14.763, 5.184, 8.362, P<0.05). After propensity score matching, the above indices were 77, 66, 33, 96, 47, 70, 73, 105, 38, 79, 64 in the LND group, and 79, 64, 29, 88, 55, 71, 72, 112, 31, 74, 69 in the control group, respectively, showing no significant difference in the above indices between the two groups (χ²=0.056, 0.329, 2.158, 0.014, 0.936, 1.400, P>0.05). (2) Intraoperative and postoperative situations: the operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion, cases with postoperative complications, and duration of postoperative hospital stay were 265 minutes (range, 160-371 minutes), 300 mL (range, 200-500 mL), 37, 46, 12 days (range, 9-17 days) for the LND group, and 59 minutes (range, 46-250 minutes), 200 mL (range, 100-400 mL), 24, 25, 9 days (range, 7-11 days) for the control group, respectively. There was no significant difference in the volume of intraoperative blood loss or cases with intraoperative blood transfusion between the two groups (Z=1.700, χ²=3.520, P>0.05). There were significant differences in the operation time, cases with postoperative complications, and duration of postoperative hospital stay (Z=6.520, χ²=8.260, Z=4.270, P<0.05). (3) Follow-up: 143 patients in the LND group was followed up for 18-26 months. The 1-, 3-, 5-year survival rates were 66.9%, 32.8%, 25.0%, and the median survival time was 22.0 months (range, 18.0-26.0 months). In the control group, 143 patients were followed up for 11-32 months. The 1-, 3-, 5-year survival rates were 71.7%, 38.0%, 31.0%, and the median survival time was 22.0 months (range, 11.0-32.0 months). There was no significant difference in the overall survival between the two groups (χ²=0.466, P>0.05). (4) Survival analysis: results of univariate analysis showed that distance from margin to tumor, tumor diameter, the number of tumors, microvascular tumor thrombus, and lymph node metastasis by pathological examination were related factors for prognosis of patients undergoing radical resection of ICC (χ²=10.662, 9.477, 16.944, 6.520, 11.633, P<0.05). Results of multivariate analysis showed that distance from margin to tumor<1 cm, tumor diameter>5 cm, multiple tumors, microvascular tumor thrombus, positive lymph node metastasis by pathological examination were independent risk factors for prognosis of patients undergoing radical resection of ICC (hazard ratio=0.600, 1.571, 1.601, 1.750, 1.723, 95% confidence interval: 0.430-0.837, 1.106-2.232, 1.115-2.299, 1.083-2.829, 1.207-2.460, P<0.05). Conclusion Lymph node metastasis is an independent risk factor affecting the prognosis of ICC patients, and it is necessary to perform LND in radical resection for patients with ICC and lymph node metastasis.
