RESUMEN
Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.
RESUMEN
Objective:To investigate the predictive effect of neutrophil to lymphocyte ratio (NLR) for recurrence-free survival after liver transplantation in hepatocellular carcinoma (HCC) patients.Methods:The clinical data of 84 HCC patients who underwent liver transplantation in the 900th Hospital of the Joint Logistics Team, PLA, from January 2012 to December 2019 were included in this retrospective analysis. There were 73 males and 11 females, with an average age of 51 years. Univariate and multivariate Cox regression analyses were performed. The distinguishing ability of NLR for predicting recurrence-free survival in patients with HCC after liver transplantation was analyzed using the receiver operating characteristic (ROC) curvee. The two groups were generated according with the cut-off value, and the recurrence-free survival time to make the Kaplan-Meier survival curve.Results:The area under the ROC curve of NLR for predicting recurrence-free survival after liver transplantation in patients with HCC was 0.683, Yoden index was 0.319, and the optimal threshold was 3.2.Univariate analysis showed that maximum tumor diameter, number of tumors, Milan criteria, and NLR were associated with recurrence-free survival after liver transplantation in patients with HCC (all P<0.05). Multivariate analysis showed that maximum tumor diameter ( HR=2.412, 95% CI: 1.277-4.555), number of tumors ≥3 ( HR=5.595, 95% CI: 2.023-17.531) and NLR≥3.2 ( HR=2.891, 95% CI: 1.348-6.204) were independent risk factors for recurrence-free survival of HCC patients prediction after liver transplantation (all P<0.05). The 1-year recurrence-free survival rate was 78% in the NLR<3.2 group ( n=61), which was superior to 58% in the NLR≥3.2 group ( n=23), and the difference was statistically significant ( P<0.05). Conclusion:Tumor diameter, number of tumors and NLR are risk factors affecting the prognosis of liver transplantation in patients with HCC, and high serum NLR may indicate recurrence-free survival in patients with HCC after liver transplantation.
RESUMEN
Objective To investigate the feasibility of liver transplantation in the treatment of inoperable hilar cholangiocarcinoma. Methods The clinical data for 3 patients with unresectable hilar cholangiocarcinoma who underwent liver transplantation in the Department of Hepatobiliary Surgery of Fuzhou General Hospital of People's Liberation Army from January 2006 to December 2012 were retrospectively analyzed. The patients were followed up by phone, outpatient service, and hospitalization. The starting point of the follow-up was the operation date. The patients death was the end point. The clinical and pathological features, postoperative survival, tumor recurrence, and prognostic factors were observed. The follow-up deadline was December 2017. Results All 3 patients underwent classical orthotopic liver transplantation using retrograde perfusion through inferior vena cava and no perioperative deaths occurred. All 3 patients were followed up for 10 to 132 months. During the follow-up period, of 1 patient who died of tumor recurrence, the pathological TNM stage was T4a N1 M0, and both had Union for International Cancer Control stage Ⅳa, and the tumor-free survival time was 3 months, and the survival time was12 months. Of 1 patient who died of other causes, the pathological TNM stage was T3N1 M0, and both had Union for International Cancer Control stage Ⅲ, and the tumor-free survival time was 12 months, and the survival time was12 months. One case as of the end of follow-up, the patient has survived for 132 months, the pathological TNM staging was T2a NOM0, and both had Union for International Cancer Control stage Ⅱ. Conclusions Lymph node positive and high pathological TNM stage were poor prognosis factor for hilar cholangiocarcinoma who underwent liver transplantation. Patients with early hilar cholangiocarcinoma who don't have lymph node metastasis are expected to benefit from liver transplantation.
RESUMEN
Objective To investigate the expression of long-chain non-coding RNA gastric cancer high expression transcription factor 1 (GHET1) in hepatocellular carcinoma (HCC) and the correlation with prognosis,cell proliferation,migration and invasion.Methods 20 HCC patients who underwent surgery from Fuzhou General Hospital of Chinese People's Liberation Army from March to May 2016 were included.The HCC tissue and adjacent normal tissue of 182 patients from June 2012 to December 2013 were retrospectively collected.According to the median value of GHET1 expression,it was divided into GHET1 high expression group and low expression group,91 cases each.Huh7 and HepG2 cells were divided into:blank control group (Con) with serum-free medium,siRNA-GHET1 group transfected with siRNA-GHET1,and negative control group (siRNA-NC) transfected with negative control sequence.The expression of GHET1 was detected by real-time fluorescence quantitative polymerase chain reaction,and the effect of GHET1 on HCC cells was analyzed by CCK-8,Transwell assay and Western blot.Results Compared with adjacent normal tissue,the relative expression of GHET1 mRNA in HCC tissues was significantly increased.Compared with LO2 cells,the mRNA expression of GHET1 in Huh7 and HepG2 cells was higher (P＜0.05).The GHET1 high expression group had tumor＞5 cm,vascular invasion,AFP＞400 μg/L,Edmonson grade Ⅰ,and the tumor-free ratio was lower in the expression group (P＜0.05).Survival analysis showed that HCC patients with high GHET1 expression had a poorer prognosis than patients with low expression.Multivariate Cox regression analysis showed that high expressed GHET1,vascular invasion (HR=2.067,95％ CI:1.350 to 3.162),and without tumor capsule are independent predictors of recurrence in HCC patients.After transfection with Huh7 and HepG2 cells,the proliferation of siRNA-GHET1 group was significantly decreased comparing with Con and siRNA-NC groups.Compared with siRNA-NC group,the migration and invasion ability of siRNA-GHET1 group decreased,and E-cadherin expression increased.The expression of fibronectin and vimentin decreased,and the difference was statistically significant (P＜0.05).Conclusions The expression of GHET1 in HCC tissue is higher comparing with normal tissue,which increases the proliferation,migration and invasion of hepatoma cells.It is an independent predictor of prognosis in HCC patients and a potential target for clinical treatment.
RESUMEN
Objective To investigate the biliary complications and recovery of liver function after liver transplantation from citizen's deceased donors (DCD) versus standard criteria donors (SCD).Method The clinical data of 269 patients who underwent orthotopic liver transplantation from January 2009 to December 2016 at the Fuzhou General Hospital were collected.197 livers were from SCD and 72 from DCD.Propensity score matching (PSM) was used to compare the biliary complications and recovery of liver function after liver transplantation in the two groups.Results PSM matched 61 pairs of patients.There were 10 (16.4％) and 8 (13.1％) biliary complications in the DCD and the SCD groups,respectively,with no significant difference between them (P ＞ 0.05).The recovery of liver function was significantly delayed in the DCD group when compared with the SCD group.The levels of ALT,AST,GGT and AKP in the DCD group were significant different on the postoperative first,third,fifth,seventh and fourteenth day (P ＜ 0.05).At 30 days after surgery,there was no significant difference in liver function between the two groups.Conclusions Liver grafts from DCD had a significant impact on the recovery of liver function.When compared with the SCD group,the DCD group recovered significantly slower in liver function.There was no significant increase in the incidence of biliary complications.
RESUMEN
Objective To evaluate the value of preoperative model for end-stage liver disease combined with serum sodium (MELD-Na) score for the prediction of the incidence of acute kidney injury (AKI) early after liver transplantation. Methods Clinical data of 315 recipients undergoing orthotopic liver transplantation by retrograde inferior vena caval perfusion were retrospectively analyzed. According to preoperative MELD-Na score, all patients were divided into group A (MELD-Na score≤10, n=115), group B (10<MELD-Na score≤20, n=118) and group C (MELD-Na score>20, n=82). Preoperative and intraoperative parameters of the recipients were statistically compared among three groups. Preoperative parameters included serum creatinine (Scr), blood urea nitrogen (BUN), albumin (Alb), total bilirubin (TB), prothrombin time-international normalized ratio (PT-INR), mean arterial pressure (MAP) and serum Na+,etc. Intraoperative parameters included operation time, vena caval occlusion time, hemorrhage volume, quantity of red blood cell infusion, quantity of plasma transfusion and total fluid infusion volume, etc. The incidence and staging of AKI early after liver transplantation in the recipients were statistically compared among three groups. Spearman's rank correlation analysis was performed to analyze the correlation between preoperative MELD-Na score and AKI staging. Results Preoperative BUN, Alb, TB, PT-INR, MAP and Na+ in the recipients significantly differed among three groups (all P<0.05). Intraoperative vena caval occlusion time, hemorrhage volume, quantity of red blood cell infusion and quantity of plasma transfusion significantly differed among three groups (all P<0.05). In 315 recipients undergoing liver transplantation, the incidence of AKI within postoperative 1 week was 64.8% (204/315), and 43% (49/115), 71% (84/118) and 87% (71/82) in group A, B and C. Statistical significance was identified among three groups (all P<0.05). Spearman's rank correlation analysis revealed that preoperative MELD-Na score was positively correlated with AKI staging (r=0.442, P=0.000). Conclusions MELD-Na score not only acts as a parameter evaluating preoperative patients' conditions, but also serves as a pivotal parameter predicting postoperative incidence of AKI.
RESUMEN
Objective To study the expressions of HnRNPA1 in patients with recurrent or metastatic hepatocellular carcinoma (HCC) after liver transplantation.Methods The expressions of HnRNPA1 protein in pericarcinoma and normal liver tissues were detected using Western blot analysis in 16 patients with HCC.Immunohistochemical analysis was done in 141 patients with HCC.All these patients underwent liver transplantation.The relationship between the expressions of HnRNPA1 with recurrent and metastatic HCC were analyzed.Results The positive expression rate of HnRNPA1 protein in the HCC tissues (75.0％,12/16) was significantly higher than that in the pericarcinoma tissues (18.8％,3/16) (P ＜ 0.01).The expression of HnRNPA1 was positively correlated with tumor size,TNM type,vascular invasion and tumor encapsulation (P ＜ 0.01).Tumor recurrence in the HnRNPA1 high expression group was significantly higher than that in the HnRNPA1 low expression group (x2 =15.577,P ＜ 0.01).The survival rate was significantly lower in the high HnRNPA1 expression than that in the low expression group (x2 =6.309,P ＜0.05).Conclusion The expression of HnRNPA1 protein was a marker which predicted HCC recurrence or metastasis in patients after liver transplantation.
RESUMEN
Objective To investigate the role of preoperative peripheral blood neutrophil to lymphocyte ratio (NLR),platelet to lymphocyte ratio (PLR),prognostic nutritional index (PNI) in the prognosis of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after radical operation.Methods This is a retrospective study,involving 426 surgically resected hepatitis B related hepatocellular carcinoma cases in a single center from 2003 to 2012.Results Kaplan-Meier analysis showed patients in NLR ≤ 1.62 group achieve higher rate of recurrence-free and overall survival than that in the NLR ＞ 1.62 group,the difference was statistically significant (P ＜ 0.005);Also PNI ＞ 49.42 group showed higher rate of overall survival significantly than PNI≤49.42 group (P ＜ 0.005).The results of Cox regression multivariate analysis further suggested that both NLR ＞ 1.62 (HR 1.74,P =0.007) and PNI ≤49.42 (HR 0.70,P =0.021) were independent risk factors for overall survival,NLR ＞ 1.62 (HR 1.45,P =0.03) was also an independent risk factor for recurrence-free survival.Conclusion The preoperative NLR and PNI may be independent risk factors for prognosis of patients with HBV-related HCC after radical operation.
RESUMEN
Objective To investigate the clinical effect of cryosurgery in the preoperative preparation of liver transplantation in treating liver cancer.Method This study reviewed retrospectively clinical data from 74 patients who underwent cryosurgery of liver cancer before liver transplantation.According to the differences between transplantation programs,74 patients were divided into 2 groups:26 patients in Argon-helium cryoablation group (AHC group) and 48 patients in transcatheter arterial chemoembolization group (TACE group).Whether the patients in two groups met the standard of Milan after treatment,as well as the incidence rate of complication,waiting time for transplantation and MELD score before transplantation were compared between two groups after preoperative therapy.What's more,operation time,no liver time,amount of bleeding,PT and serum level of aminotransferase at 1st,3rd,and 5th day after transplantation were analyzed.Abdominal drainage fluid volume,the incidence of infection,acute rejection,kidney failure,biliary complication,and vascular complication in two groups were also compared.Disease free survival rate was counted after two years by outpatient follow-up.Result Only 3 cases in two groups exceeded Milan standard after treatment,one in AHC group and two in TACE group.The complication incidence and waiting time in two groups had no statistically significant differences.The MELD score in AHC group was significantly lower than in TACE group before transplantation.The operation time,amount of bleeding and transfusion requirements in AHC group were also significantly lower than in TACE group.The time without liver in two groups had no statistically significant difference.The speed of liver function recover was faster in ACH group,and the abdominal drainage fluid volume was less.There were no significant differences in incidence of postoperative complications between two groups (P＞0.05).Conclusion Cryosurgery therapy has little effect on liver functions after treatment.It is a good therapy for liver cancer patients before liver transplantation.
RESUMEN
Objective To analyze and compare the clinical effects of comprehensive treatment and liver transplantation for hepatocellular carcinomas (HCC)exceeding Milan criteria.Methods A retrospective analysis was performed on the clinical data of 157 patients with HCC (exceeding Milan criteria)who received comprehensive treatment (99 patients,including 48 cases meeting Shanghai criteria)and liv-er transplantation (58 patients,including 26 cases meeting Shanghai criteria)in our hospital from January 2006 to January 2010.The medi-an survival times and 1 -,2-,and 3-year survival rates were calculated by the Kaplan-Meier method,and the log-rank test was used for survival difference analysis.Results For all patients,the median survival times of the comprehensive treatment group and liver trans-plantation group were 18.00 ±1.15 and 23.40 ±4.44 months,respectively,and their 3 -year survival rates were(18.2 ±3.9)% and (39.7 ±6.4)%,respectively;the survival was significantly improved by the treatment of liver transplantation (P=0.009).For patients meeting Shanghai criteria,the median survival times of the comprehensive treatment group and liver transplantation group were 20.00 ±1.17 and 36.00 ±0.00 months,respectively,and their 3-year survival rates were (25.0 ±6.3)% and (57.7 ±9.7)%,respectively;there was significant survival difference between the two groups (P=0.008).For patients exceeding Shanghai criteria,the median survival times of the comprehensive treatment group and liver transplantation group were 16.00 ±1.78 and 16.00 ±1.69 months,respectively,and their 3-year survival rates were (11.8 ±4.5)% and (25.0 ±7.7)%,respectively;there was no significant survival difference between the two groups (P=0.221).Conclusion Compared with comprehensive treatment,liver transplantation leads to a significant higher long-term survival rate in HCC patients exceeding Milan criteria but meeting Shanghai criteria.However,the two therapies cause no significant survival difference in HCC patients exceeding Shanghai criteria.
RESUMEN
Objective To investigate the effective strategies to prevent and treat biliary complications after orthotopic liver transplantation.Methods The clinical data of 316 patients who received orthotopic liver transplantation at the Fuzhou General Hospital of Nanjing Military Command from November 2001 to March 2012 were retrospectively analyzed.Cold perfusion with HTK + UW solution was applied when obtaining the liver graft,and then the liver graft was preserved in the UW solution.The bile duct was perfused with UW solution thereafter.Orthotopic liver transplantation or piggyback liver transplantation were adopted in the cadaver liver transplantation.Left liver transplantation and right liver transplantation were adopted in the living donor liver transplantation.Choledochojejunal Roux-en-Y anastomosis or duct-to-duct choledochostomy were used for biliary reconstruction.Ordinary T tubes were used for drainage before 2006,and then 6 F pediatric suction catheter or epidural catheter were applied for drainage thereafter.The Ttube was pulled out 3-6 months after the operation.Enteral nutrition was applied to patients at the early phase after operation.The immunosuppressive agents used including tacrolimus + mycophenolatemofetil + adrenal cortical hormone,and for some patients,tacrolimus + mycophenolatemofetil + sirolimus + hormone were used.Patients were followed up for 2 years to learn the incidence of biliary complications and guide the medication.The difference in the incidence of bile leakage between patients who wcrc admitted before 2006 and those admitted after 2006 were compared using the chi-square test.Results The warm ischemia time was 2-6 minutes,and the cold ischemia time was 3-10 hours.For patients who received cadaver liver transplantation,orthotopic liver transplantation was carried out for 291 times and piggyback liver transplantation for 24 times; biliojejunal Roux-en-Y anastomosis was carried out for 5 times and bile duct end-to-end anastomosis for 310 times.For patients who received living donor liver transplantation,1 received left liver transplantation and 1 received right liver transplantation,and they received bile duct end-to-end anastomosis.A total of 311 patients received immunosuppressive treatment with tacrolimus + mycophenolatemofetil + adrenal cortical hormone,and 5 patients reveived tacrolimus + mycophenolatemofetil + sirolimus + hormone.Of the 316 patients who received orthotopic liver transplantation,38 had biliary complications after the operation,including bile leakage in 18 patients,intra-and extra-hepatic bile duct stricture in 6 patients,anastomotic stricture in 6 patients,biliarycomplications included cholangitis in the portal area and cholestasis in 4 patients,choledocholithiasis and cholangitis in 2 patients and biliary infection in 2 patients.The incidence of bile leakage before 2006 was 14.00％ (7/50),which was significantly higher than 4.12％ (11/267) of bile leakage after 2006 (x2-7.676,P ＜ 0.05).Of the 38 patients with biliary complications,the condition of 35 patients was improved,and 3 patients died.Of the 18 patients with bile leakage,15 was cured by conservative treatment,3 received surgical treatment (the condition of 1 patient was improved by drainage,anti-infection treatment and nutritional support,but died of peritoneal hemorrhage at postoperative 1 month; 2 patients received peritoneal drainage,1 was cured and 1 died of peritoneal infection).For the 6 patients with intra-and extra-hepatic bile duct stricture,1 was cured by liver retransplantation and 5 were cured by conservative treatment,endoscopic retrograde cholangio-pancreatography (ERCP) or balloon dilation.For the 6 patients with anastomotic stricture,the condition of 3 patients was improved by conservative treatment,balloon dilation or stent implantation,1 gave up treatment due to hepatic cancer recurrence and died thereafter,1 received anastomosis + T tube drainage,1 was cured by recurrent tumor resection and choledochojejunostomy.Four patients with cholangitis in the portal area and cholestasis were cured by conservative treatment.For the 2 patients with choledocholithiasis and cholangitis,1 was cured by stent implantation with ERCP,and 1 received conservative treatment,and the level of total bilirubin was decreased.Two patients with biliary infection were cured by anti-infection treatment.Conclusions Most of the biliary complications could be treated by non-surgical treatments.For patients with severe biliary complications or those could not be treated by non-surgical treatment,re-exploration of the bile duct is effective.Liver re-transplantation is the only choice for patients with dysfunction of liver graft caused by severe ischemic biliary injury.
RESUMEN
Objective To compare the efficacies of hepatectomy and liver transplantation for patients with hepatocellular carcinoma (HCC) fulfilling the Milan criteria.Methods From July 2002 to February 2009,121 patients with HCC combined with hepatic cirrhosis fulfilling the Milan criteria were admitted to the Fuzhou General Hospital.Eighty-nine patients who received hepatectomy were in the hepatectomy group,and 32 patients who received liver transplantation were in the liver transplantation group.There were no significant difference in the age,gender,etiology of liver disease,the size of the largest tumor,number of tumors,microscopic venous invasion,microsatellite lesion and tumor differentiation between the 2 groups.The clinical data of the patients in the 2 groups were retrospectively analyzed.The overall survival and disease-free survival were evaluated by Kaplan-Meier method,and differences in survival rates between the 2 groups were determined by Log-rank test.COX proportional hazard was used for univariate and multivariate analysis to evaluate the risk factors for prognosis.Results The median period of follow-up was 37 months.The 1-,3-,5-year survival rates were 86％,63％ and 44％ in the hepatectomy group,and 87％,70％ and 62％ in the liver transplantation group.There was no significant difference in the overall survival rate between the 2 groups (x2 =1.092,P ＞ 0.05).The 1-,3-,5-year disease-free survival rates were 68％,44％ and 26％ in the hepatectomy group,and 80％,65％ and 52％ in the liver transplantation group.There was a significant difference in the disease-free survival rate between the 2 groups (x2 =4.712,P ＜ 0.05).The result of univariate analysis revealed that microscopic venous invasion and microsatellite lesion were significantly correlated with the survival (Wald =9.625,7.340,P ＜ 0.05),and the result of multivariate analysis indicated that microscopic venous invasion was the independent risk factor influencing the survival (Wald =5.008,P ＜ 0.05).Conclusions As for patients with HCC fulfilling the Milan criteria,the overall survival rate of patients who received hepatectomy is not different from those who received liver transplantation,but the disease-free survival rate of patients who received liver transplantation is higher than those who received hepatectomy.Microscopic venous invasion is an independent risk factor influencing the survival.
RESUMEN
Objective To investigate the methods for reconstructing portal vein in liver transplantation patients with grade Ⅳ portal vein thrombosis.Methods Clinical data of 6 patients with grade Ⅳ portal vein thrombosis who underwent liver transplantations were analyzed retrospectively.Different portal vein reconstructing approaches were applied: 4 patients underwent portal vein anastomosis with internal organ varicosis vein (group A),and 2 patients underwent portal vein arterialization (group B). Portal venous flow was monitored by intraoperative ultrasound and postoperative liver function was tested periodically during follow-up.Results In group A,one patient died of celiac infection 2 months post-transplantation.The remaining three patients were followed up for 14-17 months,and their portal veins remained smooth without thrombosis and with mitigated esophageal varicosity.In group B,one patient,with recurrent upper gastrointestinal bleeding,died of celiac infection 47 days after liver transplantation.The patient was followed up for 33 months with satisfactory liver and kidney functions although stomach esophagus varicosity was aggravated.Portal vein blood flow in groups A and B was 1258 ± 345 and 2275 ± 247 ml/min respectively after anastomosis by intraoperative color Dopplar ultrasound monitoring. Aspertate aminotransferase (AST) in group B was significantly lower on the fourth day after liver transplantation,and alanine aminotransferase (ALT) in group B was significantly lower on the 3rd,4th,5th and 6th day after liver transplantation than in group A (all P＜0.05).Serum total bilirubin (TBIL) had no statistically significant difference during the 10 days post-operation (P＞0.05).Conclusion Patients with grade Ⅳ portal vein thrombosis may achieve a satisfactory clinical effect by reconstructing portal vein through anastomosis of donor portal vein with internal organ? varicosis vein.PVA may be associated with early recovery of graft function and may be an effective remedial measure for patients with grade Ⅳ portal vein thrombosis who undergo liver transplantation.
RESUMEN
Objective To study the effects of ischemia-reperfusion in liver transplantation on the pathophysiological changes of the lung and mechanisms of lung injury. Methods We studied 23 patients who received liver transplantation at Fuzhou General Hospital of PLA. We cut a small piece of the right lung for pathological study and for L-1β and TNF-a immunohistochemistry studies at 5 minutes after the beginning of operation (Ta), 5 minutes before the portal vein was opened (Tb) and three hours after the new liver was transplanted (Tc). We also collected peripheral blood to study the concentration of IL-1β and TNF-a in the plasma at the beginning of operation (T1), the portal vein 5 minutes before opening, the portal vein (T2) ten minutes after the opening (T3) , and one hour after the new liver was transplanted (T4), three hours after the new liver was transplanted (T5), and 12 hours after operation (T6). Results The cytokines TNF-a and IL-1β in peripheral blood were not obviously increased in the portal vein before it was opened, but were significantly increased after the portal vein was opened. Comparison of T1 and T2 separately with T3, T4 and T5 showed significant differences (P<0. 01). In light and electron microscopy, the structures of the lung tissues were normal at Ta and did not change significantly at Tb. There were significant abnormalities at Tc. The average positive points of TNF-a and IL-1β expressions in the lung tissues at Tc were significantly higher than Ta and Tb(P<0. 01). Conclusion Ischemia-reperfusion in liver transplantation led to a serious systemic inflammatory syndrome,and acute lung injury. TNF-a and IL-1β were involved in acute lung injury.
RESUMEN
BACKGROUND: Hepatitis B virus (HBV) recurrence following liver transplantation has been difficultly treated, and antiviral therapy following HBV recurrence has been less reported yet.OBJECTIVE: To investigate the antiviral therapy using Adefovir + Lamivudine + anti-hepatis B immunoglobulin on liver functional improvement following liver transplantation.METHODS: A total of 208 cases with hepatitis B-related end-stage liver disease following liver transplantation were selected from Liver Transplantation Center of Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from January 2005 to October 2008. All patients were treated with Lamivudine + anti-hepatis B immunoglobulin so as to prevent from HBV recurrence. At 6-43 months after following up, HBV recurrence was found in 19 cases, including 13 with positive HBeAg and 8 with YMDD mutation. The 19 patients were treated with Adefovir based on the application of Lamivudine + anti-hepatis B immunoglobulin.RESULTS AND CONCLUSION: At 12, 24, and 48 weeks after treatment, DNA and glutamic-pyruvic transaminase of 19 cases were significantly decreased (P < 0.01). After 48-week treatment, recovery rate of glutamic-pyruvic transaminase, negativity rate of HBeAg, and negativity rate of HBV DNA were 84.1 %, 76.92%, and 78.9%, respectively. The results demonstrated that the application of Adefovir + Lamivudine + anti-hepatis B immunoglobulin effectively inhibited viral replication and prevented HBV recurrence following liver transplantation.
RESUMEN
BACKGROUND: The affected liver can be completely removed by liver transplantation,long-term efficacy is superior to liver resection,the 5-year survival rate reaches 70% H1.In addition,liver transplantation can avoid a serious risk for incomplete liver function caused by hepatic resection in the case of liver dysfunction.OBJECTIVE: To retrospectively analyze the treatment effects and importance of orthotoplc liver transplantation for primary hepatic cancer patients.METHODS: A total of 75 patients with primary hepatic cancer treated by orthotopic liver transplantation in Department of Hepatobiliary Surgery,Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from March 1980 to December 2008 were involved in the analysis for the postoperative survival rates and recurrence of tumors.RESULTS AND CONCLUSION: For all the patients,the total postoperative survival rate in the 1st,2nd and 3rd year was 86.6%,66.7% and 53.3% respectively,the disease free survival rate was 65.2%,53.9%,34.1%.Their mean survival time is 25 months.For the patients in line with Milan standard,the postoperative survival rate in the 1st,2nd and 3rd year was 88.4%,72.5% and57.9% respectively,the disease free survival rate was 77.6%,62.3%,51.8%.Their mean survival time is 39 months.Tumor recurrence occurred within one year in all six patients who were beyond Milan standard.Two patients died in one year after operation,the survival rate at postoperative one year was 66.7% and the remanent four patients all died in the 2nd year after operation.Orthotopic liver transplantation was one of the effective treatments for pdmary hepatic cancer patients.The patients which were measured up to Milan standard would have the best curative effects.
RESUMEN
Objective To investigate the efficiency of model for end-stage liver disease(MELD)score,serum sodium concentration and aseites condition in the evaluation of short-term survival rate of patients with benign end-stage hepatopathy after liver transplantation.Methods The clinical data of 98 patients with benign end-stage hepatopathy who had undergone liver transplantation in Fuzhou General Hospital from January 1999 to February 2007 were retrospectively analyzed.The relationship between serum sodium concentration.ascites condition and the prognosis of patients with the same MELD score was analyzed.Kaplan-Meier survival curve was drawn.The 1-year survival rate of the patients was analyzed by chi-square test.The mortality of patients with the same MELD score at the end of the third month after operation was analyzed by Fisher's exact test.Results MELD score of aIJ patients was 15-25 or＞25.The postoperatire 3-month mortality rates of patients with serum sodium concentration≥130 mmol/L were 5%and 15%.which were significantly lower than 33%and 55%of those with serum sodium concentration＜1 30 mmol/L.The difference upon 1-year survival rates between them had statistical significance(x2:12.88,P＜0.05).The postoperative 3-month mortality rates of patients without ascites were 5%and 8%.which were lower than 35%and 57%of those with aseites.and the difference upon 1-year survival rates between them had statistical significance(X2=15.26.P＜0.05).Conclusions It is more accurate to evaluate the short-term survival rate after liver transplantation for benign end-stage hepatopathy by combining the MELD score with serum sodium concentration and ascites condition.
RESUMEN
Objective To explore a better method for establishing rat model of simultaneous (liver)-kidney transplantation and the prevention of complications after transplantation.Methods In the donor operation, the liver and the right kidney were flushed with 0-4 ℃ sodium lactate Ringer’s (injection) through aorta, and en bloc resection of organs of right kidney, liver, pancreas, intestines, and spleen were done. Preparation was performed in the preservation solution. During the recipient (operation), all the blood vessels were reconstructed with cuff methods. The bile duct was anastomosed using a simple inside bracket. Operation of connecting ureter attached part of bladder with the bladder was conducted.Results One hundred and ten simultaneous liver-kidney transplantations including 50 (preliminary) experiments were carried out. Eighteen recipient rats died in the preliminary experiments. Five recipient rats died in the formal experiments and all the remaining had survived for more than 30 days. The successful rate of formal transplantations was 91.7 %.Conclusion This kind of rat model of simultaneous liver-kidney transplantation is simple. The time for blood vessel anastomosis and (anhepatic) stage was reduced. Complications such as stenosis were avoided. Preparation before operation, manipulation after operation and management after operation can affect the establishment of the model.
