Objective To evaluate the effect of parecoxib combined with ropivacaine for incision infiltration on agitation during recovery from anesthesia in patients undergoing abdominal hepatectomy. Methods Forty patients of both sexes, aged 35-64 yr, with body mass index of 18-24 kg∕m2 , of Ameri-can Society of Anesthesiologists physical statusⅠ or Ⅱ, undergoing elective partial hepatectomy, were di-vided into parecoxib sodium group ( group P ) and parecoxib sodium plus ropivacaine group ( group RP ) with 20 cases in each group. Parecoxib sodium 40 mg was intravenously injected at 30 min before operation in group P. Parecoxib sodium 40 mg was intravenously injected at 30 min before operation, and incision in-filtration was performed with 0. 5% ropivacaine 20 ml at the end of surgery in group RP. Patient-controlled intravenous analgesia was performed at the end of surgery in both groups. The development of agitation, re-spiratory depression and nausea and vomiting was recorded within 30 min after operation. Blood samples were collected from the radial artery immediately before induction ( T0 ) , at the end of surgery ( T1 ) and at removal of extubation ( T2 ) for determination of plasma cortisone ( Cor) concentrations ( by radio-immunity method), plasma epinephrine (E) and norepinephrine (NE) concentrations (by enzyme-linked immu-nosorbent assay) and blood glucose ( using a blood gas analyzer) . Results Compared with the baseline at T0 , the plasma concentrations of Cor, Glu, E and NE were significantly increased at T1,2 in two groups ( P>0. 05) . The incidence of agitation and plasma concentrations of Cor, Glu, E and NE were significantly low-er at T1,2 in group RP than in group P ( P<0. 05) . No patients developed nausea and vomiting and respira-tory depression in two groups. Conclusion Parecoxib combined with ropivacaine for incision infiltration can decrease the occurrence of agitation during recovery from anesthesia, which is related to inhibiting stress responses of patients undergoing abdominal hepatectomy.

Hepatocellular carcinoma (HCC) is mostly treated by surgery combined with interventional therapy, chemotherapy, radiotherapy and local treatment. However, it often relapses after the operation. And the prognosis of advanced patients is poor, and the effective rate of chemotherapy and molecular targeted therapy is low. Recent studies indicated that the occurrence and progress of HCC are closely related to the immune function of the body. Immunotherapy, as a new type of tumor therapy, has drawn much attention. By improving the immunogenicity of tumor cells and the killing sensitivity of effector cells, it stimulates the immune function of the body, prolongs the progression-free survival time and the overall survival time of patients, and becomes an integral part of the comprehensive treatment of liver cancer. This article reviewd the progress in immunotherapy of HCC in the recent years.

Objective:To study the safety and efficacy of liquid isolation assisted technology in ultrasound-guided percutaneous radiofrequency ablation for hepatocellular carcinoma adjacent to liver surfaces.Methods:A retrospective study was conducted on 246 patients with hepatocellular carcinoma near liver surfaces treated by radiofrequency ablation from November 2016 to November 2019 at the Department of Hepatobiliary and Pancreatic Surgery, Affiliated Tumor Hospital of Zhengzhou University. There were 182 males and 64 females, aged (56.7±9.2) years. The patients were divided into the liquid isolation group with liquid isolation assisted technology for radiofrequency ablation ( n=131) and the conventional treatment group with conventional radiofrequency ablation ( n=115). The complication, one-time complete ablation and progression-free survival rates were compared between the two groups. Results:The incidence of intraoperative complications in the liquid isolation group was 21.4% (28/131), versus 20.9% (24/115) in the conventional treatment group. There was no significant difference between the two groups ( P>0.05). The incidence of postoperative complications in the liquid isolation group was 20.6% (27/131), which was significantly lower than that in the conventional treatment group 33.9% (39/115) ( P<0.05). The incidence of postoperative pain in the liquid isolation group was 6.1% (8/131), which was significantly lower than that in the conventional treatment group 15.7% (18/115) ( P<0.05). For the 131 patients in the liquid isolation group, there were 183 tumors near to liver surfaces. For the 115 patients in the conventional treatment group, there were 142 lesions near to liver surfaces. The one-time complete ablation rate in the liquid isolation group was 94.0% (172/183), which was significantly higher than the 75.4% (107/142) in the conventional treatment group ( P<0.05). The progression-free survival rate in the liquid isolation group was significantly better than that in the conventional treatment group ( P<0.05). Conclusion:The liquid isolation technique increased the one-time complete ablation rate of liver cancer adjacent to liver surfaces, reduced the incidence of postoperative complications and improved prognosis.

Objective:To compare the clinical outcomes between the new cold-circulation bipolar radiofrequency assisted versus Habib-4X bipolar radiofrequency assisted open hemihepatectomy.Methods:A retrospective study was conducted on 45 patients who underwent bipolar radiofrequency assisted open hemihepatectomy at the Affiliated Tumor Hospital of Zhengzhou University from October 2016 to January 2020. There were 28 males and 17 females, with an average age of 52.2 years. These patients were divided into the experimental group ( n=20) who underwent the new cold-circulation bipolar radiofrequency assisted open liver resection, and the control group ( n=25) who underwent the Habib 4X bipolar radiofrequency assisted open liver resection. The postoperative alanine aminotransferase (ALT), postoperative aspartate aminotransferase (AST), liver coagulative necrosis plane width, speed of liver parenchymal transection, electrode needle carbonization rate, and postoperative complications were compared between groups. Results:In the experimental group, the speed of liver parenchymal transection was (5.0±2.0) cm 2/min, the width of the coagulative necrosis plane was (1.36±0.21) cm, the AST on the first postoperative day was (177.0±79.3) U/L, the ALT on the first postoperative day was (200.2±78.5) U/L, and the electrode needle tip carbonization rate was 20.0% (4/20). These figures were significantly better than the control group with (3.6±1.7) cm 2/min, (1.93±0.16) cm, (233.2±66.6) U/L, (249.2±62.9) U/L, and 56.0% (14/25), respectively (all P<0.05). The postoperative complication rate was 15.0% (3/20) in the experimental group and 24.0% (6/25) in the control group ( P>0.05). Conclusion:Cold-circulation bipolar radiofrequency assisted hemihepatectomy was safe and feasible. It had the advantages of rapid transection of liver parenchyma, a low electrode tip carbonization rate, and a more accurate coagulation range.
