Two types of emulsions and suspensions were prepared using 40% Lipiodol (LIP)and Ultra-Fluid Lipiodol(UFL)with mitomycin C(MMC)by the“pumping techni- que”.The physical stabilities of each preparation were examined microscopically and macro scopically.The drug release test was made by using dissolution tester uhder rotating oar method,the concentrations of MMC released from the preparations were determined spectro- photometrically.The results showed that the emulsion was unstable,underwent phase separation easily and drug release rapidly.The stability of the emulsion was related to the proportion Lipiodol and aqueous solution(oil/water ratio),The ratio of 4:1 was ruich made stable than that of 2:1.The stability of the UFL emulsion was better than that of the LIP. The suspension was mare stable than the emulsion.The UFL suspension was much more suitable for clinical use because of not so viscons than the LIP.

Objective To investigate the effects and adverse events of Yiaisanjie soup combined with sustained release fluorouracil in treating pancreatic cancer.Methods From January 2012 to December 2015,the clinical data of 62 cases with pancreatic cancer in Deqing County People's Hospital were retrospectively analyzed,which were divided into combination group and control group.The combination group underwent the implantation of sustained release fluorouracil panicles under CT guidance and took Yiaisanjie soup once a day for at least 5 cycles of 3-week administration and then 1-week no administration.The control group was treated only by sustained fluorouracil panicle implantations.The blood samples at fasting were collected before and 1 week after treatment to detect serum tumor markers.The adverse events were recorded.The therapeutic effect for solid tumors was evaluated according to response evaluation criteria in solid tumors(RECIST).Results Before treatment,CEA,CA125,CA242,CA19-9 in 2 groups had no statistical differences.After treatment,these tumor markers obviously decreased in both groups compared with before treatment.Compared with the control group,the CEA,CA125,CA242,CA50 and CA19-9 in combination group decreased at a more significant degree,and the difference was statistical significant (P ＜ 0.05).The incidence of Ⅱ and Ⅲ degree thrombocytopenia,nausea,vomiting and diarrhea was significantly lower in the combination group than in the control group (12.12％ vs 34.48％,18.18％ vs 48.28％,9.09％ vs 41.38％,all P＜0.05).There were 10 cases with partial remission (PR),17 cases with stable disease (SD) and 6 cases with progressive disease (PD),and the total effective rate was 81.8％ (27/33) in the combination group.There were 5 cases with PR,15 cases with SD and 9 cases and PD,and the total effective rate was 69.0％ (20/29) in the control group.The difference was not statistically significant (x2 =1.390,P =0.119).Conclusions The therapeutic effect of Yiaisanjie soup combined with sustained release fluorouracil in treatment of pancreatic cancer is not obvious,but the combination can significantly reduce serum tumor markers and reduce the incidence of side effects.

Resolution of the complications after liver transplantation is one of the important factors related to prognosis. Hepatic artery thombosis (HAT) after liver transplantation can lead directly to trans- planted liver undergone necrosis, biloma formation and liver functional exhaustion. The early diagnosis with Color Doppler which should be the first method of choice, CTA, MRA and angiography could lead to exact demonstration, and proper treatment can result in better prognosis. The microinvasive techniques such as local thrombolysis, balloon dilatation and stent placement are safe and effective for treatment of hepatic artery thombosis. The vascular reconstruction and oxygen hyperbaric are effective therapeutic methods. Repeat liver transplantation is still the last important choice for survival.

Objective To study the changes and significance of HBV DNA and it's antigen and antibody in patients with liver transplanting.Methods 35 cases with liver transplanting in 302th hospital from Oct.2006 to Mac.2007 has been studied.The HBV antigen and antibody has been studied by ELISA in 188 samples including one from before transplanting and 4 to 7 from after transplanting.The quantitative of HBV DNA has been detected by real time PCR technology.45 cases of hepatitis B,whose sera HBV DNA is positive no more than 10 000U/ml,treated with lamifudine in 2 weeks about has been used in controls.Results 95(34/35)percent of liver-transplanting patients acquired serum-transfer in HbsAg to it's antibody,and 6 patients with HBeAg positive acquired from HbeAg to it's antibody in 2 days after transplanting.The HBV DNA in sera is distinguished of 34 cases from 35s in 6 months after liver-translpanting.Only one patient is insisting with HBsAg and HBV DNA positive.In lamifudine treatment controls,none of patients acquired sera-transferred from HBsAg to antibody in 45 cases.The HBV DNA is decreased from positive to negative under cove in 11 controls.29 cases of HBV DNA are decreased in 2 to 3 Log E after treatment with lamifudine.The HBV DNA is insisting in high levels in 5 patients.The HBeAg is negative in 29 cases after lamifudine treatment,but it's antibody is not acquired serum transferring.Conclusion The HBV DNA,HbsAg and HbeAg in patients with HBV infection may be transferred into negative forever transplanting with healthy liver underlined in HBIG and lamfudine treatment.

Objective To investigate the expression and correlation of serum hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) level pre-and post-transcatheter arterial chemoembolization (TACE) in patients with primary liver cancer (PLC) .Methods Expression of serum HIF-1α and VEGF were studied in 40 patients of PLC pre-and 1 day,1 week,1 month post-TACE and 20 healthy volunteers (as control group) .Results The expression of HIF-1α and VEGF was (154.94±83.29) pg/ml and (264.00±148.10) pg/ml before TACE,higher than those in control group (P＜0.01) .The expression of HIF-1α and VEGF was (570.64±230.87) pg/ml and (362.07±102.25) pg/ml in PLC patients 1 day post-TACE,higher than those before TACE (P＜0.01) ; (198.62±92.11) pg/ml,and (283.52±145.46) pg/ml 1 week post-TACE; (133.96±57.02) pg/ml and (150.96±84.89) pg/ml in the complete response (CR) group 1 month after TACE, (255.74±123.44) pg/ml and (368.95±161.90) pg/ml in partial response (PR) and stable disease (SD) group (P＜0.05) .The expression of serum HIF-1α was positively correlated with VEGF before TACE,and the serum HIF-1α also correlated with portal vein tumor thrombosis and metastasis.Serum VEGF was also correlated with clinical stage,portal vein tumor thrombosis and capsule.Conclusion The expression of serum HIF-1α and VEGF plays an important role in relapse of tumor,and contributes to the evaluation of the efficacy of TACE and metastasis of PLC.

Arterial steal syndrome(ASS),a scarce complication after liver transplantation,is charac-terized by hepatic arterial hypoperfusion of the graft caused by a shifting of blood flow into the splenic,left gastric,or gastroduodenal arteries. It can lead to stricture formation of biliary system and transplanted liver function exhaustion. The early diagnosis and treatment are important for protecting the transplanted liver function. Dynamic CDFI after liver transplantation as a routine is necessary to find out the suspected lesions,and transcatheter angiography as the gold standardization can give clear dignosis. Embolization of splenic artery is minimally invasive,successful and less complication treatment for ASS and especially the coil embolization of middle segment of splenic artery is the best choice.

The insufficient blood supply to the portal vein after liver transplantation, mainly caused by portal vein stenosis (PVS)or portal vein thrombosis(PVT), occurs low in incidence but would be serious enough to lead to graft failure. Prompt diagnosis and treatment is critical to allow graft salvage. The color Doppler flow image (CDFI) could be the first choice for testing portal venous flow, and angiography is reliable for further accurate diagnosis on meaningful functional change of the stenosis. The interventional therapy , including percutaneous balloon angioplasty and stent placement, is safe and effective in lowering the portal venous pressure after hepatic transplantation with portal vein stenosis. Thrombolysis, percutaneous mechanical fragmentation and stent placement ,as the treatments of early portal vein thrombosis, are effective therapeutic methods, and TIPS is also a proper management if necessary.

The occurrence rate of the obstruction of the hepatic vein or the inferior vena cava is very low. Obstruction can develop acutely as a result of technical problems or can present itself much later after the transplantation due to intimal hyperplasia or perianastomotic fibrosis. Clinically, the common presentations include hepatic dysfunction, liver engorgement, ascites, abdominal pain, etc. Percutaneous endovascular treatment with balloon dilation or stent placement is a safe and effective alternative treatment, which can keep the vessels open for a long period of time. Angioplasty can achieve technical success in restoring anastomotic patency almost to 100% of cases, but, unfortunately, restenosis occurs frequently. For adult patients or pediatric patients with adult-sized hepatic veins, stenting seems to be the optimal choice.

Objective To introduce the technique of percutaneous biliary drainage for treatment of malignant biliary obstruction and to eveluate its therapeutic effect. Methods Percutaneous biliary drainage was performed in 47 patients with malignant biliary obstruction. The biliary obstruction occurred in the common bile duct of 10 patients, in the common hepatic duct for 13, at the conjuction of right and left hepatic ducts in 24. The inner outer draining catheter, the metallic stent or plastic endoprosthesis was placed to drain the bile internally if the obstruction could be passed with guide wire after percutaneous transhepatic cholangiography, or the outer drainage could only be carried out. Results The internal drainage was done with stent in 15 patients and with plastic endoprosthesis in 3, the inner outer drainage in 15, and the external drainage in 14. The serum total bilirubin decreased from 514.1?204.3?mol/L before the procedure to 238.4? 142.8 ?mol/L one week after the procedure( P
