Objective To Investigate the indications, surgical technique and perioperative management of orthotopic liver transplantation.Methods Orthotopic liver transplantation was successfully performed on a unresectable liver cancer on caudate lobe, 2 cases with Caroli’s disease and 7 cases with advanced liver cirrohosis. A 11 year’s old girl with Caroli’s disease was performed on one reduced size liver transplantation (RSLT). Results The recovery of liver graft function was good after the operation in those patients without perioperative death. The case of liver cancer died of recurrent cancer on the 139th postoperative day, 1 case died of severe fungus infection and one died of gastric stress ulcer perforation, other 7 cases recovered well without complications. Conclusion The results suggest that unresectable central liver cancer, terminal liver cirrohosis or benign liver diseases combined with severe liver disfunction are good indications for liver transplantation. Good surgical technique and perioperative management are key points to succucess of the liver transplantation.
Objective To determine whether Rb gene is involved in the genesis of primary hepatocellular carcinoma(HCC). MethodsForty paraffin specimens of primary HCCs with corresponding adjacent liver tissues and normal liver tissues were investigated for Rb protein expression by tissue chip and SP immunohistochemical technique. ResultsLoss of Rb protein expression occurred in 17 of 40 tumor samples, whereas in 4 of 40 adjacent liver tissue samples, only 1 of 40 normal liver tissue specimens showed negative Rb staining.Rb protein deletion in HCC was higher than that in adjacent tissues and normal liver tissues (P＜0.05).Rb protein deletion rate doesn’t correlated remarkably with tumor size or phathology grade of HCC （Pgt;0.05）. ConclusionRb protein deletion may play an important role in the tumorigenesis of HCC.Tissue chip is an effective highthroughput technique platform for the study of tumor molecular pathology.
【Abstract】ObjectiveTo construct a recombinant eukaryotic expression vector for human endostatin in order to study the inhibitory effect of liposome-mediated endostatin gene on the growth of human liver carcinoma in nude mice. MethodsHuman endostatin cDNA including IL-2 secreting peptide was cloned into eukaryotic expression plasmid pcDNA3.0 to construct recombinant plasmid pCD-sEndo. pCD-sEndo plasmid was transferred into hepatocarcinoma cell line SMMC-7721 mediated by liposome Dosper, the expression and secretion of endostatin gene was detected by RTPCR and Western blot analysis. The suspension of SMMC-7721 cells was injected subcutaneously at the back of 32 nude mice to establish the model of human liver carcinoma. The mice were divided into 4 groups randomly, and injected with Dosper+pCD-sEndo, Dosper+pcDNA3.0, Dosper and physiological brine separately. Tumor volume was measured by stages. The mice were executed after the drug had been given for 1 week, then the microvessel density (MVD) of the tumor tissue was detected with immunohistochemical method and apoptotic index of tumor cells was measured by TUNEL-stain. ResultsThe eukaryotic expression vector pCD-sEndo was successfully constructed and was confirmed by enzyme digestion and sequence analysis. Expression of endostatin gene was detected in transfected SMMS-7721 cells by RTPCR in vitro, and endostatin protein was also detected in the supernatant of transfected SMMS-7721 cells by Western blot. In vivo study, the growth of human liver carcinoma was inhibited in the group injected with endostatin gene: the average volume of tumor in this group was significantly smaller than that in other groups （P＜0.05）; the average MVD in this group was 6.2±2.5, significantly less than that in the group injected with physiological brine (32.8±6.4), Dosper （27.8±6.4）, or Dosper+pcDNA3.0 (25.5±5.5), P＜0.05. The average apoptotic index of tumor cells in treatment group, brine group, Dosper group and Desper+pcDNA3.0 group was 24.5±7.3, 7.6±2.5, 9.5±3.0 and 11.2±3.6 respectively, it was evidently higher in the treatment group than in the latter three groups. ConclusionHuman endostatin mediated by cation liposome could decrease the microvessel number of implanted human hepatocarcinoma in nude mice. It could also accelerate apoptosis of tumor cells and inhibit growth of tumor.
ObjectiveTo compare the efficacy and safety of Huaier and Sorafenib in treatment of small hepatocellular carcinoma(HCC)following radical resection. MethodsEighty-two patients with small HCC accepted radical liver resection and then taken Huaier or Sorafenib were collected retrospectively. These patients were divided into Huaier group(51 cases)and Sorafenib group(31 cases)according to the different administration drugs after operation. The baseline characteristics, tumor characteristics, survival rate, tumor recurrence rate, and side effects were compared between two groups. Results①There were no significant differences on the baseline demographic characteristics, liver function, and tumor characteristics between two groups(P > 0.05).②The overall survival rate and tumor-free survival rate had no significant differences between the Huaier group and the Sorafenib group(P=0.737, P=0.699).③The rate of recurrence or metastasis had no significant difference between the Huaier group and Sorafenib group(37.3% versus 32.3%, P=0.648). The most common site of the recurrence or metastasis was the liver and the lung followed.④There were only 5 cases suffered side effects after taking Huaier and no case needed Huaier discontinuance. However, 11 cases suffered side effects after taking Sorafenib and 3 cases needed Sorafenib discontinuance, and the rate of the side effect in the Sorafenib group was much higher than that in the Huaier group(35.5% versus 9.8%, P=0.026). ConclusionFor the small HCC who accepted radical liver resection, Huaier seems to be an effective and safe drug.
ObjectiveTo investigate status of readiness for hospital discharge of patients with liver cancer after radical surgery and to explore its influencing factors.MethodsA cross-sectional survey was conducted, a total of 200 patients with liver cancer after the radical resection who were planned to discharge within 1 to 2 days in this hospital from January to April 2019 were selected as the study subjects. The general informations and informations relevant readiness for hospital discharge of patients were investigated and analyzed by the questionnaire.ResultsIn this study, 200 questionnaires were distributed, of which 195 were recovered, and 184 were valid, the final effective recovery rate was 92% (184/200). The scores of 4 dimensions of readiness for hospital discharge in 184 patients: The own status was 42.55±12.36, disease knowledge was 51.68±17.58, and response ability was 21.05±6.86, social support available was 31.85±7.56, and the total score of readiness for hospital discharge was 147.07±36.25. One hundred and eighty-four (80.4%) of 184 patients were prepared to discharge. The univariate analysis results showed that the readiness for hospital discharge score was related to the gender, monthly income per household, preoperative comorbidities, and time with tube after the operation (P<0.05); Further the multiple regression analysis showed that the monthly income per household and preoperative comorbidities were the important influencing factors for it (P<0.05).ConclusionsAccording to results of this study on readiness for hospital discharge of patients with liver cancer after operation in this hospital, readiness for hospital discharge is better, and gender, monthly income per household, preoperative comorbidities, and time with tube after operation are influence factors for it, of which monthly income per household and preoperative comorbidities are important influencing factors.
【Abstract】ObjectiveTo study the mechanism of spontaneous rupture of hepatocellular carcinoma (HCC). MethodsArticles have been reviewed to find out the theory of spontaneous rupture of HCC. ResultsResearchful results suggested that the injury of small arteries was usually followed in patients of spontaneous rupture of HCC. In this review, the immune complex, which composed of hepatitis B virus e antigen, complement C1q and immunoglobulins, was found deposited in the elastic membrane of arteries. Likely as a result of immune complex deposition, vascular injury occurs mainly in the small arteries where the deposition of immune complex was present. The small arteries in which immune complex deposited are readily injuried and cause hemorrhage and rupture of HCC during vascular load increase. ConclusionWe would conclude that immune complex deposition in vessel wall led to the small arteries injury may be the factor involved in the pathogenesis of spontaneous ruptured HCC.
Objective To explore the correlation of Gli1 expression with clinical characteristics and prognosis of liver cancer. Methods Such Databases as PubMed, Embase, CNKI, Wanfang Database and Chinese Biomedical Literature Database were searched to collect cohort studies, which has published on the correlation between the expression of Gli1 and the clinical pathologic features of liver cancer and its prognostic value from the establishment of the databases to December 2016. Results Twelve studies with a total of 831 patients were included in this study. The high expression of Gli1 was associated with the tumor diameter >5 cm [relative risk (RR)=1.39, 95% confidence interval (CI) (1.08, 1.79)], clinical stage [RR=1.26, 95%CI (1.05, 1.51)], intrahepatic metastasis [RR=1.39, 95%CI (1.06, 1.83)] and venous invasion [RR=1.44, 95%CI (1.01, 2.04)], but the correlation of Gli1 expression was not significant with gender, histological differentiation, tumor diameter >3 cm, hepatitis B virus, cirrhosis and alpha fetoprotein. Meanwhile, the results of Meta-analysis showed that the higher Gli1 expression in liver cancer patients had a worse 3-/5-year overall survival rate and overall survival rate than those of the lower Gli1 expression group [3-year, RR=3.38, 95%CI (2.01, 5.67); 5-year, RR=1.51, 95%CI (1.19, 1.91); overall survival, RR=1.60, 95%CI (1.11, 2.30)]. And the higher Gli1 expression in liver cancer patients had a worse disease free survival rate than that in the lower Gli1 expression group [RR=1.89, 95%CI (1.35, 2.66)]. Conclusion The high expression of Gli1 is associated with poor prognostic outcome in liver cancer, and may be used as an important prognostic marker for patients with liver cancer.
