BACKGROUND: Tumor recurrence in liver transplant recipients greatly affects prognosis of liver transplantation with hepatocellular carcinoma (HCC). How to prevent tumor recurrence has aroused increasing attention. Arsenious acid chemotherapy is considered effective on treating moderate or advanced liver cancer, but its utilization following liver transplantation remains few. OBJECTIVE: To explore the role of arsenious acid on tumor recurrence in liver transplant patients with primary HCC extending Milan criteria. RESULTS AND CONCLUSION: All patients were routinely followed up for 3-32 months. Thirty recipients were presented with tumor recurrence, 16 in the chemotherapy group and 14 in the non-chemotherapy group. Tumor recurred in lung, liver graft and bones in most cases. The total recurrence rate was similar in these two groups, but chemotherapy could delay recurrence after transplantation (P=0.026). There was no significance in 6-month, 1-year survival rate between two groups, but the 2-year survival in the chemotherapy group was higher (P=0.037); 6-month tumor-free survival rates in the two groups had no significance, 1-year and 2-year tumor-free in the chemotherapy group were significantly higher than those in the non-chemotherapy group (P=0.030, 0.023). Intravenous arsenious acid chemotherapy can delay tumor recurrence and prolong survival in liver transplant patients with HCC extending Milan criteria.

Objective To explore the prevalence of osteoporosis (OP) and vertebral osteoporotic fracture (OPF) and related risk factors in patients with rheumatoid arthritis (RA).Method A total of 644 patients with RA from Jan.2010 to Oct.2013 were recruited,anteroposterior and lateral X-rays examination of vertebral column (T5-L5) were conducted,and semi-quantity method were used as the standard for judging vertebral OPF.Meanwhile,patients' clinical and laboratory data including daily dosage of glucocorticoid,duration of glucocorticoid usage,cumulative amount dosage of glucocorticoid were recorded in details.158 normal subjects were selected as control group.Results (1)The prevalence of vertebral OPF in patients with RA was 16.6％.Bone mineral density (BMD) of all measured lumbar vertebra in RA group were markedly decreased[(0.97 ±0.22) g/cm2].The total prevalence of OP at lumbar vertebra in RA was 17.9％ (81/452),which was significantly higher than that of control group (4.4％,7/158) (P ＜ 0.001).(2) The percentage of OP in RA patients with vertebral OPF was significantly higher than that in patientswithout OPF [40.6％ (41/101) vs 11.4％ (40/351) ;P ＜ O.001].Patients with OPF were of older age,longer use of glucocorticoid,more cumulative amount dosage of glucocorticoid,longer disease duration,higher scores of health assessment questionnaires (HAQ) and increased ESR (P ＜ 0.05).(3) Logistic regression analysis revealed that age (OR =1.094,95％ CI 1.065-1.125,P ＜0.001) and gender(1 =male,2 =female) (OR=5.600,95％ CI 2.097-15.087,P =0.001) were the risk factors for the development of OP in RA,while body mass index (BMI) was the protective factor (OR =0.770,95％ CI 0.696-0.853,P ＜ 0.001).Age (OR =1.031,95％ CI 1.009-1.053,P =0.005) and occurrence of OP at lumbar vertebra (OR =3.765,95％ CI 2.092-6.776,P ＜ 0.001) were risk factors of the development of OPF in RA patients.Logistic regression analysis also showed that RA was the risk factor of OPF (OR =4.716,95％ CI 1.987-11.192,P ＜ 0.001),even after the adjustment of age,gender and BMI.(4) Receiver operator characteristic(ROC) curve in RA patients with OPF has found that age-OPF and daily dosage of glucocorticoid-OPF AUCRoC were 0.689 and 0.636 respectively.The cut-off value in ROC curve of age and daily dose or treatment course of glucocorticoid-OPF were 54.5 years and 6.25 mg(P ＜0.001),while duration of glucocorticoid usage-OPF AUCROC was 0.685,with cut-off value in ROC of age-OPF 135 days(P ＜ 0.001).Conclusion Prevalence of OPF in patients with RA increases remarkably.Old age and OP at spine are risk factors related to the development of OPF in patients with RA.

Objective To examine the plasma β-catenin and DKK1 levels in patients with rheumatoid arthritis (RA) and to explore their relationship with bone and joint damage in RA.Methods One hundred and thirteen patients with RA and 120 healthy individuals were recruited into this research.Bone mineral density (BMD) in the femur and lumbar spine were measured with dual-energy X-ray absorptiometry (DEXA).Radiographs for two hands were evaluated according to the Sharp's method.Serum levels of β-catenin and DKK1 in all patients with RA and healthy controls were detected by enzyme-linked immunosorbent assay (ELISA).The 2-tailed independent samples t test was used for measurement data.Chi-square test was used for the enumeration data.Correlation analysis,linear regression and Logistic regression analysis were used as appropriate statistical analysis.Results ① Significantly higher serum levels of DKK1 were observed in RA patients than that in healthy controls [(8±7) vs(6±4) μg/ml,t=2.552,P=0.012],while there was no sinnificant difference with regard to the levels of β-catenin between the two groups.② Compared to control groups,patients with RA had lower BMDs at femur and lumbar spine (P＜0.01).Furthermore,incidence of osteoporosis (OP) in RA (31.9％,36/113) was remarkablely higher than that in healthy subjects (15.0％,18/120) (x2=9.290,P=0.002).③ There were obvious discrepancies in age,swollen joint count (SJC),swollen joint count index (SJI),alkaline phosphatase (AKP),joint narrowing space score,joint erosion score,Sharp score between patients with osteoporosis and without osteoporosis (P＜0.05).④ In RA group,DKK1 level was posi-tively related with plasma erythrocyte sedimentation rates (ESR),28-jonit disease activity score (DAS28),AKP,joint narrowing space score (P＜0.05).Serum β-catenin level was associated with ESR,AKP in RA (P＜0.05).⑤ Multiple linear regression analysis indicated that in the RA group,disease duration (b=0.709,t=9.560,P＜0.01,95％CI:2.154-3.286),HAQ (b=0.151,t=2.052,P=0.043,95％CI:0.234-15.243),DKK1(b=0.286,t=2.057,P=0.043,95％CI:0.034-2.028)were the contributors for joint space narrow score(R2=0.580,F=24.745,P＜0.01).⑥ Multiple Logistic regression analysis showed that the Sharp score (OR=1.018,P＜0.01,95％CI:1.008-1.028) was the risk factor for the occurrence of osteoporosis at femur in RA,while age (OR=1.087,P=0.012,95％CI 1.019-1.159) was the risk factor for osteoporosis at lumbar spine.Conclusion Serum DKK1 levels in RA increase significantly,while there is no apparent alteration in plasma β-catenin.Serum DKK1 is correlated with disease activity and joint space narrow score.

Objective To investigate the value of serum receptor activator of nuclear factor kappa B ligand (RANKL)/osteoprotegrin (OPG) ratio in osteoporotic fracture (OPF) of patients with rheumatoid arthritis (RA).Methods Three hundred and eighty four RA patients with mean age of (49 ± 14) y (16-82) admitted in the First Affiliated Hospital of Anhui Medical University from 2010 to 2013 and 158 sex-and age-matched healthy subjects were enrolled in the study.OPF was diagnosed by X-ray examination and BMDs of femur and lumbar spine 2-4 (L2-4) were measured by dual energy X-ray absorptiometry.Levels of RANKL and OPG in the peripheral blood of 220 RA patients and 100 normal subjects were detected by ELISA method.Results Eighty-two cases of OPF was diagnosed in 384 RA patients (21.35％),the rate was higher than that in controls (3.80％,6/158,x2 =25.371,P ＜0.01).The peripheral blood levels of RANKL (0.150 ± 0.143 vs.0.101 ± 0.066,t =4.178,P ＜ 0.01),OPG (0.457 ± 0.293 vs.0.359 ±0.216,t=3.347,P=0.001) and ratio of RANKL/OPG (0.41 ±0.35 vs.0.34±0.20,t =2.111,P=0.036) in RA patients were significantly higher than those in control group.In comparison with normal controls,BMDs of all detected regions in RA were decreased significantly (P ＜0.01).The incidence of osteoporosis in RA (121/327,37％) was higher than that in normal controls (22/158,13.92％) (x2 =27.291,P ＜ 0.01).RA patients with OPF had higher age (t =4.377,P ＜ 0.01),longer duration of disease (t =2.612,P =0.009),higher RANKL level (t =3.554,P =0.001),higher RANKL/OPG ratio (t =2.651,P =0.010),higher health assessment questionnaires (HAQ) score (t =2.418,P =0.016),lower serum calcium level (t =2.183,P =0.030),lower hemoglobin level (t =2.125,P =0.036),higher Sharp score in hands X-ray examination (t =2.747,P =0.007),worse X-ray stage (x2 =7.856,P =0.049),higher glucocorticoid utilization rate (x2 =9.066,P =0.003) and higher incidence of osteoporosis (x2 =38.186,P ＜ 0.01),compared with patients without OPF.RA patients taking corticosteroids had higher incidence of osteoporosis (x2 =7.489,P =0.006) and higher incidence of OPF (x2 =9.066,P =0.003).Logistic regression analysis showed that age (OR =1.029,P =0.039,95％ CI:1.001-1.057)and the occurrence of osteoporosis (OR =3.159,P =0.001,95％ CI:1.562-6.385),RANKL/OPG ratio (OR =3.516,P =0.013,95 ％ CI:1.305-9.647) were risk factors for RA patients with OPF.Conclusion A higher incidence of OPF is prevalent in RA patients,and age,osteoporosis,taking glucocorticoids and RANKL/OPG ratio are risk factors for OPF in RA patients.

Objective To compare the effects of combined ‘en bloc' liver-pancreas transplantation (LPT) with portal vein drainage and simultaneous combined kidney-pancreas transplantation (KPT) with systemic venous drainage on the pancreatic endocrine function and related metabolism.Methods Four LPT patients and 6 KPT ones with normal hepato-renal function, good quality of life and periodic follow-up received measurement of serum insulin, insulin provocation test, fasting glucose, oral glucose tolerance test, C-peptide, glycated hemoglobin, triglyceride and total cholesterol; and their laboratory test parameters were compared and analyzed.Results In KPT group, 2-h insulin level, C-peptide level and total cholesterol level were significantly higher at 6th month, 3rd and 6th month postoperation (all P<0.05). But there was no significant difference in other parameters between the two groups at 6th month after operation.Conclusion Either KPT or LPT can achieve excellent endocrine function, carbohydrate and lipid metabolism; and the results show that portal venous drainage does not offer major metabolic advantages within 6 months after operation.

Objective To summarize the experience with salvage liver transplantation for patients with recurrent hetaptocellular carcinoma(HCC)after primary liver resection.Methods From 2004 to 2008,376 patients with HCC received liver transplantation in our single center.Among these patients,36 (9.6 %)underwent salvage liver transplantation after primary liver curative resection due to intrahepatic recurrence.There were 29 males and 7 females with the mean age of 46 years old.Sixteen received right lobectomy,10 received left lobectomy and the others received sectionectomy or segmentectomy.As a control group for comparison,we used clinical data of the 147 patients who underwent primary OLT for HCC within Milan Criteria.Results The mean interval between initial liver resection and salvage transplantation was 34.9±16.2 months(1-63 months).Intraoperative bleeding volume,transfusion volume and operative time in the salvage group were significantly different from those in control group (P<0.05).There were no significant difference in post-operative complications,tumor recurrence rate,survival rate and tumor-free survival between these two groups(P>0.05).Conclusion In comparison with primary OLT,although salvage liver transplantation would increase the operation difficulties,it still remains a good option for patients with HCC recurrence after curative resection.

ObjectiveTo summarize the clinical experience of simultaneous pancreas and kidney transplantation (SPK) after liver transplantation for patients with diabetes and uremia.MethodsThe clinical data of two patients who received SPK after liver transplantation were retrospectively analyzed.The two male patients had type 2 diabetes mellitus before liver transplantation,and suffered from endstage uremia due to diabetic nephropathy and immunosuppressant-induced toxicity.Rapid technique for combined abdominal multiple viscera procurement was performed.Kidneys,pancreas,duodenum segment and spleen were procured.Renal allograft was placed in the left iliac fossa,whereas pancreas allograft in the right iliac fossa. The pancreatic allograft exocrine secretion was drained into the proximal jejunum via a side-to-side duodenojujunostomy. Quadruple immunosuppressive regime including IL2 receptor monoclonal antibody induction,tacrolimus (Tac),mycophenolate mofetil (MMF) and steroid were used in case 1,and ATG and methylprednisolone were used in case 2.ResultsSPK was successfully applied to these two patients without serious surgical complications such as pancreatitis,graft and pancreatic fistula. The immunosuppressive regimen was based on tacrolimus with ATG induction,MMF and steroids.In the second case,serum creatinine level was decreased to the normal range within 1 week after the operation and then elevated continuously even he received empirical anti rejection treatment,Tac was tampered and rapamycin was used when the renal graft biopsy indicated drug toxicity,and creatinine level was decreased 3 weeks after the operation and recovered to the normal range at 5th week post-transplant. Both of the two patients achieved euglycemia with insulin independence about 10 days after the operation.And now these two patients have been followed up for 36 and 9 months,and the grafts function of the liver,kidney and pancreas was normal. Conclusion Immunologic reaction in patients undergoing simultaneous pancreas and kidneytransplantationafterlivertransplantationseemsmorecomplex, andareasonable immunosuppressive regimen is important to improVe the outcome.

ObjectiveTo investigate the effectiveness and tolerability of immunosuppressive regimen with daclizumab induction therapy. MethodsIn study group, 139 patients received immunosuppressive regimen with daclizumab induction therapy. In historical control group, 106 recipients received immunosuppressive regimen without daclizumab induction therapy. All patients were followed up at least for 1year. The acute rejection episodes, infectious and metabolic complications at one month and one year post-transplantation were compared between two groups.ResultsThe one-month incidence of acute rejection, new-onset diabetes mellitus, hypertension and infection was 7. 9 ％, 33. 8 ％, 21.6 ％ and 22. 3 ％, respectively in study group, as compared with 15. 1 ％, 72. 6 0％, 40. 6 ％ and 43. 4 ％, respectively in control group ( P ＜ 0. 05 ). The one-year incidence of acute rejection, new-onset diabetes mellitus, hypertension and hyperlipidemia was 10. 8 ％,5. 0 ％ ,4. 3 ％ and 7. 9 ％, respectively in study group, as compared with 19. 8 ％, 9. 4 ％, 8. 5 ％ and 14. 2 ％, respectively in control group (P＜0. 05). The one-year survival rate was comparable between two groups (P＞0. 05). ConclusionThe immunosuppressive regimen with daclizumab can enable early steroid withdrawal, significantly reduce acute rejection rate and various side effects mediated by longterm steroids use.

Objective To explore the causes and management of intra-abdominal hemorrhage after orthotopic liver transplantation (OLT). Methods Clinical data of 638 OLT patients were analyzed retrospectively from January 2004 to December 2008 in the First Affiliated Hospital of Sun Yat-Sen University. The diagnosis and treatment of postoperative intra-abdominal hemorrhage after OLT were reviewed. Results Among the 638 patients, 53 suffered from posttransplant intra-abdominal hemorrhage,the morbidity was 8. 3% (53/638). Thirty-one cases suffering from bleeding on raw surfaces or around the liver due to impairment of coagulation function were treated by non-surgery methods, 22 cases who suffered from active postoperative intra-abdominal hemorrhage due to surgical factors underwent laparotomy and bleeding control operation after failure of anti-shock treatments such as hemostatic drugs, blood reperfusion.Among the 53 patients who suffered from intra-abdominal hemorrhage, 12 patients died, and the main causes were serious infections and multiple organ dysfunction syndrome. The mortality associated with intraabdominal hemorrhage was 22. 6%. Conclusions Intra-abdominal hemorrhage at different locations were found after OLT, and the fatal rate is quite high. Timely and appropriate treatments especially laparotomy may improve the prosnosis of these patients.
