Target of the treatment for advanced pancreatic carcinoma is always palliative without prolongation of survival time almost, therefore the aims of treatment should be concentrated on improving the quality of life and alleviateing the disease-related symptoms. We do not call for the treatment and medicines that can incur obvious adverse reaction with limited effectiveness. Interventional therapy provides superexcellent short term efficacy with alleviating the disease-related symptoms significantly, and without severe side effects and thus coincides to the principle of the treatment for advanced pancreatic carcinoma. The surpassing advantages provide popular recommendation for this very kind of therapy in the recent years.

Objective To investigate the role of AT1 receptor autoantibody (AT1-AA) in the inhibitory action of irbesartan on endoplasmic reticulum stress (ERS)-related apoptotic signals in rat kidney with diabetic nephropathy (DN).Methods DN model rats were induced by high-sugar and high-fat diet plus intraperitoneal injection of streptozotocin,and the serum level of AT1-AA was detected by ELISA.These DN rats with positive or negative AT1-AA were divided into DN group and irbesartan treated group.After 4 weeks of irbesartan treatment,TUNEL staining was used to detect renal cell apoptosis.The protein and mRNA expressions of ERS chaperone protein glucose-regulated protein 78 (GRP78) and ERS-associated apoptosis proteins were determined by Western blot and RT-PCR.Results Compared with NC group,the apoptosis rate of renal cells in DN group was obviously increased,along with the increased expressions of GRP78,C/EBP homology protein (CHOP),phosphorylated c-Jun N-terminal kinase (JNK),and Caspase12 protein and mRNA (all P<0.01).The cell apoptosis and protein and mRNA levels of these genes were significantly decreased after irbesartan treatment (all P< 0.01),especially in AT1-AA positive DN rats(all P<0.05).The renal cell apoptosis rate,and protein and mRNA levels of these four genes in AT1-AA positive DN group were much greater than those in AT1-AA negative DN group (all P<0.05).Conclusions AT1-AA may be involved in ERS-related cell apoptosis in the kidney of DN rats,and play a role in irbesartan-improved renal function via inhibiting ERS-associated CHOP-JNK-Caspase12 apoptotic signals and renal cell apoptosis.

Objective To investigate the clinical efficacy of transarterial chemoembolization (TACE) combined with sorafenib for the treatment of inoperable hepatocellular carcinoma (HCC), and to discuss the influence of treatment interval on the survival time. Methods During the period from July 2008 to May 2011 at authors’ hospital, a total of 50 patients with inoperable HCC were treated with TACE together with sorafenib. The treatment intervals between each TACE procedure were recorded. The results were analyzed. Results Up to Dec. 31, 2011, the median follow-up time of the 50 patients was 310 days. The mean interval between TACE treatments was 69 days before the combination treatment was employed , while the mean interval was 112 days after the combination treatment started , and the longest interval was 648 days. Conclusion Combination treatment TACE with sorafenib can remarkably prolong the treatment interval in patients with inoperable HCC, thus the patient can get more survival benefits.

Objective To investigate the application of C- arm CT imaging technique in evaluating the efficacy of transarterial chemoembolization(TACE) for hepatocellular carcinoma(HCC). Methods During the period from Sep. 2012 to Mar. 2013 at authors’ hospital, C- arm CT scanning was employed during the performance of TACE in 80 patients with HCC. The residual active tumor lesions, Lipiodol deposition and the embolization of the feeding arteries after TACE therapy were assessed by C- arm CT plain scan images and the images of early artery phase and parenchymal phase, as well as the post- processing images. The efficacy of TACE was thus evaluated. Results A total of 139 hepatic tumors were detected in 80 patients by C- arm CT imaging. C- arm CT scanning performed immediately after TACE showed that satisfactory result was obtained in 128 lesions of 75 patients(128/139, 92.9%). Fewer, medium and more residual active tumors were seen in 78, 29 and 21 lesions respectively, while dense, moderate and thin Lipiodol deposition was seen in 64, 39 and 25 lesions respectively. After TACE therapy obvious decrease in blood supply was demonstrated in 101 lesions, while no obvious decrease in blood supply was seen in 27 lesions. Conclusion C- arm CT scanning after TACE for patients with HCC can conveniently, accurately and comprehensively reveal the residual active tumors, Lipiodol deposition and embolization status of feeding arteries. Therefore, this technique should be regarded as an important means to evaluate the efficacy of TACE.

Objective To evaluate the efficacy of transarterial interventional therapy (TAIT) in treating patients with metastatic liver cancer, and to investigate the factors influencing the prognosis of patients. Methods From January 1997 to June 2000, 470 patients with metastatic liver cancer had undergone TAIT 1231 times in the Cancer Hospital of the Chinese Academy of Medical Sciences. The clinical data of the patients were retrospectively analyzed. The short-term and long-term efficacy and the side effect of TAIT were assessed. The potential factors influencing the prognosis of the patients were determined by Cox regression analysis. Results Complete remission was observed in 94 patients, and partial remission in 143. The total effective rate was 50.4% (237/470). The median survival time was 13.5 months. The O. 5-, 1-, 2-, 3-, 5-year survival rates were 86.4%, 66. 8%, 35.6%, 16.9%, 7.3%, respectively. No severe complication occurred. The factors influencing the prognosis of the patients were: the resection of the primary tumor, blood supply of the tumor, multiple metastases of liver cancer, thrombus in the portal vein, adjuvant chemotherapy after TAIT, tumor originated from breast cancer, tumors invading multiple lobes, concurrent metastasis in other sites (X2= 17. 322, 12. 593, 8.721, 8.573, 8.492, 7. 838, 5. 623, 5. 463, P < 0.05). Conclusions TAIT is an effective palliative therapy for metastatic liver cancer which cannot be resected. The factors mentioned above influence the prognosis of patients after TAIT.

The incidence of pancreatic carcinoma is increasing obviously in recent years with a serious threat to the people's life, and yet there is not a single treatment for obtaining satisfactory prognosis. At present, the radical resection is the primary method for resectable pancreatic carcinoma, together with radiotherapy can improve the surgical resection rate and reduce the dissemination of tumors. Intraoperative radiotherapy can alleviate the pain and increase the survival rate, but the role of postoperative radiotherapy and chemotherapy is still in controversial. There is a lot of advantages for regional chemotherapy theoretically, but lack of evidence in practice. Physical therapy and biological therapy in the treatment of pancreatic carcinoma have been recognized extensively. It is possible to change fundamentally the current status of treatment and to improve the long-term survival rates with the quality of life until establishing a comprehensive treatment system mainly depended on surgical resection with combination of radiotherapy, chemotherapy, physical and biological treatment. The interventional therapy has been significantly developed as an important palliative treatment during recent years.
