RESUMO

Objective To summarize the preliminary experience of donor liver protection and function evaluation for organ donation after citizen's death. Methods Clinical data of 35 donors from organ donation after citizen's death and 33 recipients were retrospectively analyzed. Donor liver procurement and clinical prognosis of the recipients were summarized. According to serum level of sodium ion (serum sodium) before organ procurement, all recipients were divided into the serum sodium <155 mmol/L, 155-160 mmol/L and 161-180 mmol/L groups. The incidence of liver graft dysfunction early after liver transplantation was statistically compared among three groups. Results In 35 donors,27 cases were Chinese type Ⅱ and 8 cases were Chinese type Ⅲ. Thirty-three donor livers were used for liver transplantation, and the remaining 2 cases of donor livers were excluded due to congestive cirrhosis. In 33 liver transplantation recipients, 30 cases were successfully recovered. The liver function was gradually restored at postoperative 7-14 d, and normal liver function was obtained during long-term follow-up. Postoperatively, 3 recipients died including 2 cases dying from portal vein thrombosis and 1 case from pulmonary infection complicated with multiple organ failure. The incidence of early liver graft dysfunction of the recipients after liver transplantation was 18%, 23% and 4/5 in the serum sodium <155 mmol/L, 155-160 mmol/L and 161-180 mmol/L groups, respectively. Statistical significance was observed between the 161-180 mmol/L and <155 mmol/L groups (P<0.05). Conclusions Timely protection of donor liver, accurate evaluation and maintenance of liver function play a pivotal role in enhancing the utilization rate of donor liver, maintaining liver function and yielding good efficacy for transplantation.

RESUMO

Objective To investigate the safety and efficacy of hepatitis B surface antigen (HBsAg) positivity of the donors on graft survival and liver complications in HBsAg (+) renal transplant recipients.Methods We retrospectively evaluated 96 HBsAg (+) patients who received HBsAg(+) donor kidney transplant fellow-up during 20~ 139 months,in order to observe the renal allograft dysfunction,liver dysfunction and others complications.Results All 96 patients underwent renal transplantation successfully in our hospital.during the follow-up period,18 cases accepted entecavir-treated,one case lost graft function,two cases died,one of them developed drug resistance and liver function failure,the other because of cancer of the liver.Twenty-three of the 78 lamivudinetreated patients (29.5%) developed drug resistance in 7~96 months,and 3 cases developed liver function failure,2 cases died and one cured,15 of the 19 cases who been salvage treated with entecavir was successful and well tolerated after 1 year,2 cases who been salvage treated with adefovir and lamivudine with HBV DNA-negative after 12 months and 23 months.The 5-year patient/graft rates of patients who been treated with lamivudine and entecavir were 88.5%/84.6% and 88.9%/83.3% respectively.Conclusion It is safe and feasible for renal transplantation from HBsAg(+) donors to HBsAg(+) recipients with antiviral treatment,patients would require lifelong anti-viral suppression and strictly follow-up,which is important for patient and graft survival,anti-viral drugs resistance and the liver complications should be closely monitored and treated.

RESUMO

Objective To explore clinical feasibility of liver transplant from child of brain death to adult, to summarize the clinical experiences that a child of brain death transplants liver to an adult. Methods The recipient was a 39-year-old woman patient with primary hepatic carcinoma and posthepatitis cirrhosis (decompensation stage); while the donor was a 8-old-year child of brain death because of brain neoplasms. Donated liver was gained by the method of en bloc multivisceral procurement in a short time; the operative method was classic orthotopic liver transplantation. The postoperative managements included immunosuppression, prevention of infection, hepatic protection, and other relevant supports etc. Results The transplantation operative duration was 6 hours, after which not only did the recipient survive but also her body functioned well including the liver part, with no severe postoperative complications. Conclusions The technology of transplanting livers from children to adults is feasible. The key to ensure the success of transplant operation is systematic preoperative evaluation, excellent operative technique, and perfect postoperative treatment.

RESUMO

Objective To investigate the expression of Semaphorin 3F (SEMA3F) protein in hepatocellular carcinoma (HCC) and to demonstrate its relationship with clinicopathological features and prognosis of HCC. Methods Western Blotting was carried out in 32 hepatocellular carcinoma samples and matched perineoplastic tissues to detect the expression of SEMA3F protein. The relationship between SEMA3F protein expression and clinicopathological features as well as prognosis of HCC patients was analyzed. Immunohistochemistry was used to show the location of SEMA3F in HCC cells and its relationship with microvessel density (MVD). Results The expression of SEMA3F protein in HCC tissues was significantly higher than in the perineoplastic tissues (447.78± 48.26 vs 618.93 ±61.23, P<0. 05) and it was correlated closely with tumor capsulation and tumor nodular number (P<0.05). Based on the Western Blotting and clinical follow-up data, we found that the survival time of HCC patients with a higher SEMA3F expression level was longer than those with a lower level, and the recurrent/metastatic time of HCC patients was significantly different between these two groups (P<0.01). Immunohistochemistry demonstrated that SEMA3F protein localized in the cytoplasm of HCC cells and its expression correlated with HCC MVD. MVD in the low-level group was higher than the high-level group (115.6±30.38 vs 86. 56±17.94, P<0.01). Conclusions SEMA3F expression in HCC was significantly down-regulated and correlated closely with tumor-capsulation, nodular number, and MVD, implicating SEMA3F may play an important role in recurrence and metastasis of HCC. It can be regarded as a prognostic marker in HCC patients.
