Objective To evaluate argon-helium cryoablation combined with transcatheter arterial chemoembolization (TACE) in treating primary hepatocellular carcinoma by comparing the changes of AFP level and T cell immunity after the therapy with that obtained after the treatment of argon-helium cryoablation alone and with that obtained after the treatment of TACE alone. Methods (1) Ninety-nine patients with primary hepatocellular carcinoma were randomly divided into three groups: group A (n=30), treated with argon-helium cryoablation; group B (n=34), treated with TACE; and group C (n=35), treated with argon-helium cryoablation together with TACE. The patients' gender, age and pathology of three groups were comparable with each other. (2) The peripheral blood T cell immunity and AFP level both before and after the treatment were determined and the results were statistically compared. Results After the treatment the AFP level in all 3 groups was significantly reduced when compared to that determined before the treatment (P < 0.05). And the difference in the decrease of AFP level between group C and A, also between group C and B, was statistically significant (P < 0.05). After the treatment the T cell immunity, including Th, TS and Th / TS, in all 3 groups was significantly different from that determined before the treatment (P < 0.01), and significant difference also existed between group C and A and between group C and B (P < 0.01). Conclusion The statistic analysis of AFP and T cell immunity, which are regarded as the index of therapeutic efficacy, indicates that argon-helium cryoablation combined with TACE is superior to simple argon-helium cryoablation and also to simple TACE in the treatment of primary hepatocellular carcinoma.

Objective To investigate the clinical results of combined TIPSS and azygoportal disconnection for portal hypertension in controlling and preventing esophageal variceal bleeding. Methods From Oct. 1996 to Dec. 2001, 60 patients with portal hypertension were admitted to our department because of variceal bleeding and submitted to the treatment with the combination TIPSS and azygoportal disconnection. According to Child Pugh classification, 11 patients were in class A, 37 in class B, and 12 in class C. 41 patients showed mild ascites and 8 with severe ascites. The mild and severe esophageal varices were proven by upper digestive barium meal. The procedure was divided into two stages; first, TIPSS procedure with the stent of diameter 0.8cm and length 6-7cm was successfully inplanted in all patients, second, all patients underwent azygoportal disconnection two weeks later after TIPSS. Results After the combination TIPSS and azygoportal disconnection, the recent complications included three cases with bleeding at operative fields, one case with infradiaphagmatic abscess and seven with slight encephalopathy. No rebleeding of esophageal varices and death occurred during the treatment. During the follow up of 1-5 years, the rates of shunt occlusion, rebleeding and death were 11.9%, 3.5% and 7.0% respectively. Conclusions The combination TIPSS and azygoportal disconnection is an efficient therapeutic methods for portal hypertension.

Objective To study the curative effect of ischemic necrosis of femoral head by interventional thrombolysis.Methods By applying Seldinger's technique,the catheter was guided via arteria femoralis with super-selection into circumflexa femoris medialis,lataralis,and acetabuli to performed the interventional thrombolysis in 50 cases(60sides)with necrosis of femoral head.Results All patients were followed-up for 6~48 months,combined with angiography,the clinical symptoms and the change of bone.The curative effect was evaluated.The ratio of excellent and better effect was 91.4%,the ratio of the improvement of angiography was 87%.the angiography showed that after treatment,the supply artery of femoral head was increased in number;the stained area of femoral head was extended,the capillaries were incereased and the reflux of vein was remarkably improved.The ratio of the improvement of clinical symptom was 96.6%.90% of the necrotic area of femoral head showed hyperplasia,sclerosis,and reduction of cystic changes.Conclusion The interventional therapy by leading to target vascular with thrombolysis in treating necrosis of femoral head has remarkable therapeutic effect.

Objective To investigate the therapeutic effects of TNF and IL 2 recombinant adenoviruses via intra arterial injection on metastatic liver cancer in rat model. Methods Recombinant adenoviruses harboring hTNF ? or hIL 2 gene were amplified in 293 cells and subjected to titration by the pathogenetic effects on 293 cell. The rats bearing metastatic liver cancer of Walker 256 breast carcinoma were randomly grouped and administered via gastra intestinal artery with hTNF ? recombinant adenoviruses alone, or hIL 2 recombinant adenoviruses alone, or at the dose of 1.0?10 9 pfu/rat. The therapeutic effects were observed including their survival time. Results The prepared recombinant adenoviruses of hTNF ? and hIL 2 were with the titers of 2.0?10 9 pfu/ml and 2.1?10 9 pfu/ml, respectively. 1.0 ?10 9 pfu hTNF was the proper dose. Administration of hTNF ? or hIL 2 recombinant adenoviruses via hepatic artery could extend the survival time of metastatic liver cancer bearing rats, with the better therapeutic effects achieved by combinatorial administration of these two adenoviruses. Conclusion Arterial administration of adenoviruses may be an effective approach to targeted immunogene therapy for cancer.

Objective To investigate the gene transfer efficiency and lasted time in rat organs by hepatic artery injection with LacZ reporter gene recombinant adenoviruses. Methods Seven groups of rats were injected with Ad.LacZ (2?10 9 pfu/ml) and two groups of rats were injected with PBS 1 ml as control separately through gastra intestinal artery, and liver, spleen, lung, and kidney were gotten at 12 hrs, 18 hrs, 72 hrs, 7 day, 14 day, 21 day, and 28day, respectively. X gal staining was used to check up expression of LacZ gene. Results Expression of LacZ gene was detected in liver 12 hrs after injection, but none were done in spleen, lung, and kidney. Up to 21days, LacZ gene expressed in liver, but the gene expression lasted for only 14 days in spleen, lung, and kidney LacZ gene was not detected in the two control groups in all organs at 7 day. Conclusion When recombinant adenovirus was administrated through hepatic artery, the introduced gene expressed preferentially in liver. This result was the basis of intraarterial administration of cytokines gene to treat liver tumor.
