Objective To evaluate the surgical treatment of Nevin′s stage Ⅳ and Ⅴ gallbladder carcinoma. Methods A retrospective analysis was made on 62 cases of Nevin′s stage Ⅳ and Ⅴ gallbladder carcinoma patients undergoing surgical treatment from Jan. 1993 to Dec. 2002. Results There were 17 cases of stage Ⅳ and 45 of stage Ⅴ. Cholecystectomy was performed in 32 cases with a resection rate of 52%, 7 cases received radical resection, 10 extended radical resection and 15 palliative resection. The total surgical morbidity rate was 35.3%. Postoperative 1-, 3-, 5-year survival rate of radical and palliative resection were 61%, 31%, 11% and 27%, 13%, 0 respectively (P

Objective To systematically evaluate the effect of preoperative transarterial chemoembolization (TACE) on perioperative safety of patients with resectable hepatocellular carcinoma (HCC).Methods Literatures were researched using Chinese Journal Full-text Database,Wanfang database,VIP database,PubMed,Medline from December 1,1994 to May 30,2016 with the key words including “肝细胞癌,肝切除,术前化疗栓塞,经动脉化疗栓塞,liver cancer,hepatocellular carcinoma,liver resection,hepatectomy,transcatheter arterial chemoembolization,transarterial chemoembolization,preoperative” Manual retrieval was also conducted simultaneously.The randomized controlled trials (RCTs) about TACE on perioperative safety of patients with resectable HCC were received and enrolled.Patients undergoing surgery after preoperative TACE were allocated into the case group and patients undergoing first-stage resection were allocated into the control group.Two reviewers independently screened literatures,extracted data and assessed the risk of bias.Count data were described as relative risk (RR) and 95％ confidence interval (CI).Measurement data were represented as standardized mean difference (SMD) and 95％CI.The heterogeneity of the studies was analyzed using the I2 test.Results Five RCTs were enrolled in the Meta analysis,and the total sample size was 430 cases including 212 in the case group and 218 in the control group.Results of Meta analysis showed that there was no statistically significant difference in the hemihepatic resection rate between the 2 groups (RR=0.99,95％CI:0.81～ 1.20,P＞0.05).The combined resection rate of perihepatic organs in the case group was significantly higher than that in the control group (RR=3.42,95％CI:1.91-6.12,P＜0.05).Results of subgroup analysis showed that operation time and incidence of postoperative complications of patients with an average tumor diameter ＞5 cm in the case group were respectively longer and higher than these in the control group (SMD=0.31,RR=1.65,95％CI:0.06-0.57,1.01-2.69,P＜0.05).Conclusion There is no obvious effect of preoperative TACE on resectable HCC,and it can evaluated combined resection rate of perihepatic organs,operation time and incidence of postoperative complications of patients with resectable HCC and an average tumor diameter ＞ 5 cm,and also reduce the perioperative safety.

Objective To investigate and compare the dynamic changes of plasma endotoxin and CD14/TLR4 levels in the portal vein following partial liver transplantation in rats. Methods 100 %(group Ⅰ), 50 % (group Ⅱ) and 30 % (group Ⅲ) orthotopic liver transplantation models in the SD rats→SD rats were established in vivo according to "Kamada two-cuff method". Based on the principle of dynamic turbidity law, the plasma endotoxin (EU/ml) levels were determined at the postoperative time points of 1, 3, 6, 12, 24 h in recipients. The mRNA expression levels of CD14 and TLR4 in liver grafts were detected by using real-time RT-PCR. Results Under the condition of no significant difference in surgical factors, the plasma endotoxin levels in the portal vein of groups Ⅱ and Ⅲ were higher than in group Ⅰ , and reached the peak at the first h postoperation. The endotoxin levels in group Ⅱ were lower than in group Ⅲ. The endotoxin levels in sham-operation group were the highest. The mRNA expression levels of CD14 and TLR4 in groups Ⅰ, Ⅱ and Ⅲ were significantly increased as compared with sham-operation group (P＜0. 01). Conclusion There exists portal vein plasma endotoxima in 100 %, 50 % and 30 % orthotopic liver transplantation in the rats. The smaller the graft volume, the higher and longer plasma endotoxin in portal vein, so is the relative quantification of the TLR4 and CD14 mRNA in liver grafts.

Objective To explore the clinical significance and operational methods during extended radical excision for pancreatic cancer combined with portal vein ( PV )/superior mesentery vein ( SMV ) resection,and to investigate the management of iatrogenic arterial injury. Methods Clinical date of 242 patients with pancreatic cancer undergoing extended radical excision were retrospectively analyzed. All cases were divided into three groups, patients with PV/SMV resection were in group A (n = 51 ), patients with iatrogenic arterial injury during operation were in group B(n =5) ,patients without resection of vessels werein group C (n = 186 ). Operating time、volume of intraoperative blood transfusion, time of vascular interruption、the mean hospitalization,postoperative complications and postoperative survival analysis among three groups were compared with each other. Results Operating time in group A、B and C were (442. 85 ± 102. 32 ) min, ( 348. 62 ± 92. 31 ) min and ( 315.00 ± 83.43 ) min respectively, volume of intraoperative blood transfusion were ( 1430. 83 ± 1092. 43 ) ml、( 1420. 22 ± 794. 41 ) ml and ( 928. 19 ±571.57) ml respectively,operating time and volume of intraoperative blood transfusion were of significantly difference(P <0. 05) among the 3 groups,there was no significant difference in the mean hospitalization and postoperative complications. The postoperative median survival period was 18.4 months for patients of pancreatic adenocarcinoma with PV/SMV resection, the postoperative median survival period was 16. 1 months without PV/SMV resection, there was no significant difference between these by postoperative survival analysis. In the 51 cases with vessel resection,7 cases underwent partial resection of the vascular wall,44 cases underwent segmental resection, reconstruction of the portal vein was performed by end-to-end anastomosis in 38 patients, stent graft in 6 cases, the mean length of the PV/SMV resection was (2. 92 ±1.35 ) cm; latrngenic arterial injury occurred during operation in 5 patients ( 1 in hepatic artery, 1 in superior mesenteric artery, 3 in celiac think), the artery was reconstructed by end-to-end anastomosis in 4 cases,repair in 1 case. Conclusions Active and reasonable operation for pancreatic cancer with PV/SMV resection is important for improving the rate of surgical resection and the quality of life. Because of complex topography,iatrogenic vascular injury may happened frequently.

Objective:To construct a psychological support training program for palliative care specialist nurses based on positive psychology theory and make a preliminary application.Methods:From August to September, 2020, 142 palliative nursing specialist nurses in Hunan Provincial Palliative Nursing Specialist Training Base were selected as the research objects. Based on positive psychology therapy, using literature review and analysis, semi-structured interviews, expert group meetings and other methods to construct the program, and the work stress, psychological resilience and subjective well-being scores of nurses before and after 8 weeks of psychological support training were compared.Results:The program included three dimensions: cognition, emotion and behavior. After the psychological support training for 8 weeks, the nursing staff′s work stress score 80.76 ± 20.43 was lower than that before the psychological support training 84.70 ± 19.88, the difference was statistically significant( t=6.59, P<0.05), and the psychological resilience score 64.40 ±14.26 was higher than that before the psychological support training 60.19 ±15.85, the difference was statistically significant ( t=-7.39, P<0.05), and the subjective well-being score 75.70 ± 7.70 was higher than that before the psychological support training 74.13 ± 5.98, the difference was statistically significant ( t=-3.52, P<0.05). Conclusions:The psychological support training program based on positive psychology theory can reduce the the work stress, improve psychological resilience and increase subjective well-being of palliative care specialist nurses.
