Objective:To explore the safety and efficacy of camrelizumab combined with tegafur gimeracil oteracil potassium (S-1) and albumin-bound paclitaxel in the treatment of initially unresectable cholangiocarcinoma.Methods:From October 2022 to August 2024, 17 patients with unresectable intrahepatic cholangiocarcinoma and 4 patients with hilar cholangiocarcinoma were admitted to Xiangyang Central Hospital. They received treatment with camrelizumab combined with S-1 and nab-paclitaxel. Their short-term efficacy and adverse reactions were evaluated, and their long-term survival was followed up.Results:Of the 21 patients, 2 were in complete remission, 6 were in partial remission, 12 had stable disease, and 1 had progressive disease. The objective remission rate was 38.10% (8/21), and the disease control rate was 95.23% (20/21). Five patients were converted to resectable cholangiocarcinoma, with a conversion success rate of 23.81%,2 patients had complete postoperative pathological remission, and 3 patients had major pathological remission. The median progression-free survival time was 11 months (95% CI: 8.37-13.62), and the 1-year progression-free and overall survival rates were 28.57% and 95.23%, respectively. The overall adverse event rate was 90.48% (19/21), and the grade 3 adverse event rate was 28.57% (6/21). Conclusion:The combination of camrelizumab with S-1 and nab-paclitaxel for initially unresectable cholangiocarcinoma has favorable short-term efficacy, tolerable adverse reactions, and improved long-term survival for patients.

Objective To investigate the clinical efficacy of wrapping the hepatic artery with the hepatogastric ligament for preventing bleeding of the hepatic artery and its branches following pancreaticoduodenectomy(PD).Methods 194 patients who underwent PD in Xiangyang Central Hospital from January 2017 to November 2024 were enrolled and categorized into two groups based on whether the hepatic artery was enwrapped with the hepatogastric ligament during the operation.The wrapped group consisted of 95 cases where the hepatic artery was wrapped,while the non-wrapped group had 99 cases without such wrapping.Intraoperative parameters(intraoperative blood loss and operative time)and postoperative complications(pancreatic fistula,abdominal cavity infection,biliary fistula,delayed gastric emptying,postoperative bleeding,and bleeding of the hepatic artery and its branches)were compared between the two cohorts.Univariate and multivariate Logistic regression analyses were conducted to identify the independent risk factors for postoperative bleeding.Results PD was accomplished successfully in both groups.There was no remarkable difference in intraoperative indices like blood loss and operative time between the two groups(P＞0.05).Similarly,no significant disparities were noted in postoperative complications such as pancreatic fistula,abdominal infection,biliary fistula,and delayed gastric emptying(P＞0.05).Nevertheless,the incidence of postoperative bleeding in the wrapped group was lower than that in the non-wrapped group(3.16％vs.12.12％,P=0.019),and the incidence of bleeding of the hepatic artery and its branches after surgery was also significantly decreased in the wrapped group(0 vs.10.10％,P=0.004).Logistic regression analysis revealed that the operation time(OR=1.013,P=0.011),pancreatic fistula(OR=9.006,P=0.006)and celiac infection(OR=7.930,P=0.014)are independent risk factors of postoperative bleeding,Hepatogastric ligament encapsulation of hepatic artery was an independent protective factor for postoperative hemorrhage of PD(OR=0.084,P=0.006).Conclusion Wrapping the hepatic artery with the hepatogastric ligament reduces PD postoperative bleeding,especially that of the hepatic artery and its branches,without adding other complications.

Objective To explore the effects of preoperative transcatheter arterial chemoembolization(TACE)on early postoperative recurrence in the China liver cancer(CNLC)staging Ⅰb-Ⅱa patients with primary hepatocellular carcinoma.Methods The data of patients with CNLC Ⅰb-Ⅱa stage hepatocellular carcinoma who underwent curative liver resection in Xiangyang Central Hospital from May 2017 to May 2022 were retrospectively analyzed.A total of 76 patients were included,patients were divided into preoperative TACE group(n=32)and surgery group(n=44)according to whether they underwent preoperative TACE.Observe the postoperative recovery of patients.Combined with the postoperative pathological results,adjuvant TACE treatment is performed.Regular reexamination and follow-up are conducted after discharge.The Kaplan-Meier method was used to estimate survival time,calculate 95％CI,and plot the Disease-free(DFS)survival curve.The Cox proportional risk model was used for univariate and multivariate analysis.Results The 1-year disease-free survival rate in the preoperative TACE group was higher than that in the direct surgery group(96.9％vs.84.1％,P＞0.05).The 2-year disease-free survival rate in the preoperative TACE group was higher than that in the direct surgery group(90.6％vs.70.5％,P＜0.05).The disease-free survival of the preoperative TACE group was higher than the direct surgery group(23.03 months vs.20.14 months,P＜0.05).The incidence of treatment-related adverse events after surgery in the preoperative TACE group was higher than that in the direct surgery group(34.4％vs.20.5％,P＞0.05).Multivariate Cox regression analysis showed that different treatment methods,tumor number ≥ 2,and tumor microvascular invasion were prognostic factors affecting tumor recurrence.No severe adverse reactions occurred in either group,and no deaths caused by adverse reactions were observed.Conclusion Compared with direct surgery,preoperative TACE can help improve early postoperative recurrence,prolong patients'disease-free survival,and do not lead to serious adverse events.

Objective To explore the clinical application effects of Chen's pancreatojejunostomy in laparoscopic pancreaticoduodenectomy.Methods Clinical data of 176 patients who underwent laparoscopic pancreaticoduodenectomy in Xiangyang Central Hospital from January 2019 to December 2024 were retrospectively analyzed.According to the methods of intraoperative pancreatojejunostomy,the patients were divided into two groups,the research group(102 cases)using Chen's pancreatojejunostomy,and the control group(74 cases)using duct-to-mucosa pancreatojejunostomy.The two groups were compared on clinical indicators,including operation time,pancreatojejunostomy time,intraoperative blood loss,incidence of postoperative complications,length of hospital stay,and 30-day postoperative mortality rate.Results All 176 patients successfully underwent laparoscopic pancreaticoduodenectomy.There were no statistically significant differences between the two groups in intraoperative blood loss,biochemical leakage,abdominal bleeding,upper gastrointestinal bleeding,delayed gastric emptying,bile leakage,abdominal infection,and 30-day postoperative mortality rate(P＞0.05).The pancreatojejunostomy time[(22.33±5.95)min]and operation time[(334.60±66.42)min]in the study group were significantly shorter than those in the control group[(30.70±5.50)min]and[(414.46±60.96)min],with statistically significant differences(P＜0.05).Two groups of patients did not develop grade C pancreatic fistula.The incidence of grade B pancreatic fistula in the study group(5.88％)was significantly lower compared to the control group(16.22％),and this difference was statistically significant(P＜0.05).Additionally,The postoperative hospital stay of the study group patients[(17.10±6.89)days]was significantly shorter than in the control group[(20.88±8.40)days],with a statistically significant difference(P＜0.05).Conclusion Chen's pancreatojejunostomy is a feasible,safe,and effective procedure in laparoscopic pancreaticoduodenectomy,which can shorten the pancreatojejunostomy time,reduce the incidence of postoperative pancreatic fistula,and decrease the length of hospital stay.

Objective To construct a nomogram to predict the prognosis of patients with gallbladder cancer(GBC).Methods The clinicopathological data of GBC patients were extracted from the SEER database,and the independent prognostic factors of GBC patients were analyzed by Cox regression,and a nomogram was constructed.Finally,the column diagrams in the training queue and validation queue are verified.Results Age,T stage,M stage,histological grade,radiotherapy,surgery and tumor size were independent prognostic factors in GBC patients,and the differences were statistically significant(P＜0.05).In the training cohort,the C index was 0.735(95％CI=0.721～0.749),and the AUC values at 1,3 and 5 years were 0.821,0.820 and 0.833,respectively.In the verification group,the C index was 0.733(95％CI=0.711～0.755),and the AUC values for 1,3 and 5 years were 0.816,0.807 and 0.827,respectively.The calibration curve shows that the predicted values of the nomogram are in good agreement with the observed values.The decision curve shows that the nomogram model has better prediction ability than TNM staging system.Conclusion The constructed dynamic prognosis nomogram of GBC patients has high accuracy and reliability.

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.
