Objective To compare the curative results of three different therapies for earlyintermediate stage primary liver cancer. Methods The data of 428 patients with early-intermediate stage primary liver cancer treated with one of three curative therapies from April 2004 to July 2010 in our center were analyzed retrospectively. The patients were divided non-randomly into three groups: group A liver-cancer resection (n = 231), group B radio-frequency ablation (RFA) (n = 63), and group C liver transplantation (n=134). The 1-, 3-, 5-year accululative survival and recurrence rate in each group were compared. Results The accumulative 1-, 3-, 5-year survival rates were 93.3%, 71.9%, 57.2% for group A; 86.7%, 46.5%, 38.8% for group B; 95.7%, 78.3%, 72.1% for group C,respectively. The 1-, 3-, 5-year recurrence rates were 30. 3% , 49. 7%, 68. 6% for group A; 39. 3% , 58. 7% , 79. 3% for group B; 7. 0% , 12. 1% , 12. 1% for group C,respectively. There was a highly significant difference between groups A, B and C in the survival rates and the recurrence rates. The 5-year survival rate was significantly higher for group C than group A and group B (P<0. 01, P<0. 001), and the recurrence rate of 1, 3, 5-years were significantly lower for group C than for group A and B (P<0. 001). Conclusion Liver transplantation was the most effective therapy for the early-intermediate stage primary liver cancer.

Objective To evaluate the influence of hepatitis B surface antigen positive or antihepatitis B core positive donors on HBV allograft re-infection or de novo hepatitis B and recipients and grafts survival after liver transplantation.Methods Between June 2004 and December 2011,510 liver transplants were performed at our department while 387 patients were followed up.Among them,9 patients received hepatitis B surface antigen positive grafts,50 patients received anti-hepatitis B core positive grafts,and 328 patients received HBV marks negative grafts.The rate of HBV allograft reinfection or de novo hepatitis B and accumulative recipients as well as grafts survival were compared.Results All recipients with hepatitis B surface antigen positive donors remained hepatitis B surface antigen carriers after operation.HBV allograft re-infection occurred in one recipient of anti-hepatitis B core positive donor group. Five recipients with HBV marks negative donors appeared hepatitis B surface antigen positive,including two cases of Lamivudine resistance leading to HBV allograft reinfection and three cases of de novo hepatitis B from non-related diseases. The 1-,3-,5-year accumulative survival rate in anti-hepatitis B core positive grafts group,hepatitis B surface antigen positive grafts group and HBV marks negative grafts group was 100％,86％,43％; 87％,79％,57％; and 87％,80％,79％,respectively (Log-rank =1.287,P =0.525).And the 1-,3-,5-year accumulative grafts survival rate in these three groups was 100％,86％,43％; 85％,77％,56％;and 86％,79％,77％,respectively (Log rank=1.288,P =0.525).During the follow-up period,no graft loss or death was found to be related to the HBV allograft re-infection or de novo hepatitis B.Conclusion Liver grafts from anti-hepatitis B core positive donors do not increase the risk of graft loss or recipient death due to HBV allograft re-infection or de novo hepatitis B under effective antiviral therapy.Hepatitis B surface antigen positive donors are feasible to save lives or prolong life in emergency situation.

Objective To explore MRI manifestations of extrapleural solitary fibrous tumor(SFT)and to analyze the reasons of misdiagnosis.Methods MRI data of 9 cases with extrapleural SFT proved by pathology were analyzed retrospectively.Lesions location, size,shape,intensity,degrees and patterns of enhancement were assessed,and the imaging features and causes of misdiagnosis were also analyzed.Results Among 9 lesions,1 was located in the right cerebellopontine angle region,2 were in subdural-extramedullary region,4 were in the abdominal cavity and 2 were in the pelvic cavity.7 cases were misdiagnosed before operation including 1 as meningioma, 2 as schwannoma,2 as mesenchymal stem cell tumor,1 as pancreatic carcinoma and 1 as Castleman disease.8 lesions were isointense and 1 was mixed iso-or slightly hyperintense on T1WI.3 lesions were isointense,4 were mixed iso-or slightly hyperintense and 2 were mixed slightly hyperintense,iso-or hypointense on T2WI.3 lesions showed significant homogeneous enhancement after the administration of contrast agent,1 lesion showed varying degrees of enhancement and the enhancement was more remarkable in isointense area on T2WI than peripheral hyperintense area.4 lesions showed heterogeneous peripherial enhancement in the early phase,progressive filling in the late phase and finally remarkable homogeneous enhancement.1 lesion showed predominant peripheral striped enhancement in the early phase,and progressive filling and mildly inhomogeneous enhancement with patchy unenhanced area in the center of the lesion in the late phase.Conclusion The MRI features of extrapleural SFT have certain characteristics.It needs to be carefully diagnosed to improve the diagnostic accuracy.

Objective To study the impact of splenectomy and esophagogastric devascularization on the nutritional status of patients with cirrhosis and portal hypertension.Methods Sixty consecutive patients with cirrhosis and portal hypertension who underwent splenectomy and esophagogastric devascularization at the Beijing YouAn Hospital from April 5,2015 to January 23,2017 were included in this study.The body mass index (BMI),albumin (Alb),prealbumin (PA) and lymphocyte counts were prospectively collected at the end of 1-week,1-month,3-month,6-month and 1-year after surgery.The postoperative results were compared with the preoperative results in these patients.Results The BMI results obtained at 1-week and 1-month after surgery were significantly lower than the preoperative level [(22.14 ± 3.08)kg/m2 vs.(22.85 ± 3.14) kg/m2,(21.72 ± 3.05) kg/m2 vs.(22.86 ± 3.16) kg/m2,P ＜ 0.05].The BMI result at the end of 1-year after surgery was significantly elevated when compared with the preoperative level [(23.24 ± 3.64) kg/m2 vs.(22.68 ± 3.47) kg/m2,P ＜ 0.05].The ALB levels at 1-month and 3-month after surgery were significantly higher than the preoperative level [(39.87 ± 4.22)g/L vs.(35.35 ±5.15) g/L,(39.35 ± 4.75) g/L vs.(34.82 ± 5.50) g/L,P ＜ 0.05].The PA obtained at 1-week after surgery was significantly lower than the preoperative levels [(79.59 26.52)mg/L vs.(121.77 ±39.96)mg/L,P ＜ 0.05].The lymphocyte counts at all the points after surgery were significantly higher than the preoperative level (P ＜ 0.05).Conclusion Short term and long term nutritional status improved in patients with cirrhosis and portal hypertension after splenectomy and esophagogastric devascularization.

Objective To investigate the role of cytokines combined with CLIF consortium organ failure score (CLIF-COFs) for predicting the occurrence of acute respiratory distress syndrome (ARDS) in for post-liver transplant for hepatitis B-related acute-on-chronic liver failure (HB-ACLF) patients.Methods From Jul.2014 to Oct.2017,there were 37 cases of HB-ACLF undergoing liver transplantation in Beijing YouAn Hospital,Capital Medical University.According to whether the patients happened ARDS or not,37 cases were divided into ARDS group (n =9) and non-ARDS group (n =28).All patients' plasma was prospectively collected immediately before liver transplantation and on the I st,3rd,5th,7th day post-liver transplantation.The serum levels of twenty-seven cytokines were determined by 200 LUMINEX liquid chip technology.Cytokines,CLIF-COFs,clinical and biochemical indexes were analyzed with logistic regression and the receiver operating characteristic (ROC) to confirm the correlation with ARDS post liver transplantation.Results There were significant differences between HB-ACLF patients between ARDS group and non-ARDS group in age and pre-transplant infection (P ＜ 0.05).The CLIF-COFs was higher in ARDS non-without than that in non-ARDS group (P =0.019).The serum levels of vascular endothelial growth factor and platelet-derived growth factor bb were lower but IL-6 was higher post transplantation in ARDS group.The COX analysis indicated that CLIF-COFs and post liver transplantation PDGF-BB were predictors of post-LT ARDS.The area under the receiver operating characteristic (AUROC) curves was 0.728 and 0.175,respectively.The area under the curve of the discriminatory power of CLIF-COFs combined with PDGF-BB was 0.913,and the maximum Youden index is 0.786.Conclusion CLIF-COFs combines with PDGF-BB can predict the occurrence of ARDS post-liver transplantation in HB-ACLF patients.

Objective:To study the impact and the mechanism of splenectomy combined with pericardial devascularization on cirrhotic livers.Methods:Serum samples and clinical data were collected preoperatively and postoperatively from 54 patients with cirrhosis who underwent splenectomy combined with pericardial devascularization from May 2013 to Oct 2014 at Beijing You’an Hospital, Capital Medical University. Changes in hepatic arterial and portal venous blood flow, liver function and fibroscan results were analyzed. The levels of nitric oxide (NO), endothelin-1 (ET-1), interleukin-6 (IL-6), hepatocyte growth factor (HGF), transforming growth factor-β1 (TGF-β1) and matrix metalloproteinase 1 (MMP1) were measured.Results:There were 31 males and 23 females, aged(45.48±10.21)years. Free portal vein pressure decreased significantly from (37.0±7.1) cmH 2O (1 cmH 2O=0.098 kPa) to (26.1±5.7) cmH 2O after surgery ( P<0.05). Significant increases in postoperative lumen diameter (4.0±1.0) mm vs (3.1±0.7) mm were observed, accompanied by increase in peak flow velocity and blood flow of the hepatic artery. Significant deductions in lumen diameter (11.9±2.0) mm vs (13.1±1.9) mm, accompanied by reduction of peak flow velocity and blood flow of the portal vein were observed following surgery (all P<0.05). The NO level was significantly elevated immediately after splenectomy and was subsequently remained at high levels. The ET-1 level decreased 2 days after surgery and became fluctuated at low levels. The IL-6 and HGF levels increased significantly 2 days after surgery and decreased gradually after 7 days and 1 month, respectively. The TGF-β1 and the MMP1 levels increased after surgery. The endotoxin level decreased significantly after surgery (all P<0.05). Conclusion:Splenectomy combined with pericardial devascularization induced hepatic blood flow restoration, hepatocyte regeneration and reversal of fibrosis in cirrhotic livers. Splenectomy has a protective effect on cirrhotic liver when combined with pericardial devascularization.

OBJECTIVETo evaluate the influence of sirolimus on the long-term survival of patients after orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC).

METHODSClinic data of 165 consecutive patients who underwent OLT for HCC from February 2005 to March 2012 was analyzed retrospectively. Among them, 94 patients were treated with a sirolimus-based immunosuppressive protocol after OLT, while the other 71 patients with a FK506-based protocol. Postoperative survival time, survival, disease-free survival (DFS) and tumor recurrence rates between the two groups were compared.

RESULTSThe 2 groups were comparable in all clinicopathologic parameters. The sirolimus-based group had higher patient survival rates than the control group at 1-year (87% vs. 97%, P = 0.03), 2-year (80% vs. 88%), 3-year (76% vs. 85%) and 5-year (63% vs. 75%). The 1-year, 2-year, 3-year and 5-year recurrence rates were 12% vs. 3%, 17% vs. 9%, 21% vs. 9% (P = 0.04) and 31% vs. 16% (P = 0.03). Early and mid-HCC (I - II stage) of 131 cases (control group 61 cases, sirolimus-based group of 70 patients). The 1-year, 2-year, 3-year and 5-year survival rates were 90% vs. 97% , 80% vs. 90%, 78% vs. 86% and 65% vs. 82% (P = 0.04) and recurrence rates were 10% vs. 3%, 16% vs. 8%, 18% vs. 8% and 29% vs. 11% (P = 0.01).

CONCLUSIONThe sirolimus-based immunosuppressive protocol reduce long-term postoperative recurrence rate and improve the survival rate of patients after OLT for HCC significantly (especially early-mid HCC).

Objective To investigate the characteristics of hemodynamics of proper hepatic artery and portal vein after splenectomy and devascularization. Methods The clinical data of 103 patients with portal hypertension who underwent splenectomy and devascularization in the Capital Medical University-Affiliated You'an Hospital from April 2014 to February 2019 were retrospectively analyzed. Their hemodynamics of the proper hepatic artery and portal vein were recorded before and 1 week-, and 1-, 3-, 6-, 12-, and 24-months after surgery and then statistically analyzed. Continuous data with normal distribution were compared using paired-samples t test. Results Compared with the before surgery data, the portal vein diameter, portal vein flow, maximum velocity, and average velocity of the portal vein were all significantly decreased 1-week-, 1-, 3-, 6-, 12-, and 24-months after splenectomy and devascularization (all P < 0.05). The blood flow and velocity of the proper hepatic artery was significantly increased 1 week and 1 month after surgery (all P < 0.05); however, there was no statistically significant difference at 3-, 6-, 12-, and 24-months after surgery. Conclusion The diameter, flow, and flow velocity of the portal vein after splenectomy and devascularization were significantly lower than those before surgery, whereas the proper hepatic artery flow and flow velocity were increased within 1 month after surgery and then returned back to the pre-surgery levels 3 months after surgery.
