Objective To evaluate the effect of transcatheter arterial chemoembolization(TACE)together with portal vein chemoembolization(PVCE)for the treatment of advanced liver carcinomas.Methods Forty-eight patients with liver carcinoma were randomly divided into two groups.Patients in study group(n=22)were treated with TACE together with PVCE,and patients in control group(n=26)were treated with TACE alone.Results Based on the postoperative CT findings and AFP levels,the effective rate of the study group was markedly higher than that of control group and the difference between two groups was statistically significant(P＜0.05).The volume of un-embolized liver tissue in the patients of study group was obviously increased after treatment. Conclusion TACE together with PVCE is superior to TACE alone in treating advanced hepatic carcinomas.The combination of TACE and PVCE can effectively increase the successful rate of surgical resection for the advanced hepatic carcinomas.

Objective To discuss the clinical application of feeding-artery embolization in treating massive hemoptysis.Methods The feeding-artery angiography was performed in 72 patients with massive hemoptysis.Based on the angiographic findings polyvinyl alcohol(PVA)or spring coil were selected as the embolization materials.The therapeutic results were retrospectively analyzed. Results Hemoptysis was completely controned almost immediately after the embolization procedure in 46 cases,while it was obviously alleviated in 13 cases.In 11 cases the hemoptysis disappeared completely after 2-4 times of embolization treatment,and in 2 cases surgery had to be employed.Conclusion Embolization of feeding-artery with PVA particles or spring coils is an effective and safe treatment for massive hemoptysis.The key point for decreasing reoccurrence is to occlude all feeding.arteries as far as possible.

Total aralosides of Aralia elata (Miq) Seem (TASAES) from Chinese traditional herb Longya Aralia chinensis L was found to improve cardiac function. The present study was to determine the protective effects of TASAES on diabetic cardiomyopathy, and the possible mechanisms. Therefore, a single dose of streptozotocin was used to induce diabetes in Wister rats. Diabetic rats were immediately treated with low, medium and high doses of TASAES at 4.9, 9.8 mg/kg and 19.6 mg/kg body weight by gavage, respectively, for eight weeks. Cardiac function was evaluated by in situ hemodynamic measurements, and patch clamp for the L-type Ca2+ channel current (ICa2+-L) and transient outward K+ channel current (Ito). Histopathological changes were observed under light and electron microscope. The expression of pro-fibrotic factor, connective tissue growth factor (CTGF) was monitored using immunohistochemistry staining. Compared with diabetic group, medium and high doses, but not low dose, of TASAES showed a significant protection against diabetes-induced cardiac dysfunction, shown by increased absolute value of left ventricular systolic pressure (LVSP) and maximum rates of pressure development (+/-dp/dt(max)), and enhanced amplitude of ICa2+-L (P < 0.05). Histological staining indicated a significant inhibition of diabetes-caused pathological changes and up-regulation of CTGF expression (P < 0.05). The results suggest that TASAES prevents diabetes-induced cardiac dysfunction and pathological damage through up-regulating ICa2+-L in cardiac cells and decreasing CTGF expression.

BACKGROUND: Gene therapy is a popular topic in domestic and overseas studies on biological therapy for brain tumor.OBJECTIVE: By using a newly constructed eukaryotic expression vector of pCR3-TK, the effect of the HSV-TK/ACV system on the proliferative activity of human glioma cells was investigated.DESIGN: Experimental study based on cells.SETTING: Department of neurosurgery and department of oncology in a university hospital.MATERIALS: The study was conducted at the National Key Laboratory of Veterinary Biotechnology of Harbin Veterinary Research Institute from January to April in 2004. The eukaryotic expression vector of pCR3-TK was constructed by the author. The TJ905 strain was a gift from professor Pu Pei-yu, who worked in the Neurology Institute of Tianjin city. The nontransfected cells and the cells transfected with pCR3-Uni vector were set as controls.METHODS: By using Lipofectamine(a cationic liposome), the pCR3-Uni vector and the recombinant pCR3-TK plasmid(inserted with HSV-TK gene)were transfected into the human glioma cell strain-TJ905. Then the positive clones were picked out and were given ACV(50 mg/L) . Totally 72 hours later, the cover slips were collected and silver staining for nucleolus organizer regions(AgNORs) was performed.MAIN OUTCOME MEASURES: After the ACV treatment and AgNORs staining, the numbers of silver-stained granules in TJ905 cells with or without transfections were counted respectively.RESULTS: In those cells transfected with HSV-TK gene, after ACV treatment, a significant decreasing in proliferative activity could be observed, and the average numbers of the silver-stained granules in cells transfected with pCR3-Uni or pCR3-TK were 14.33 and 6.67 respectively( P ＜ 0.01).CONCLUSION: As an easy-to-operate method, AgNOR counting is helpful for the studies on the proliferative activity of cells and the investigations into the potential anti-tumor mechanism of the HSV-TK/ACV system.

Objective To introduce the techniques and clinical application of coronary arterial calcification measurements by using the multi-slice CT (MSCT). Methods The recent literature on the coronary artery calcium scoring with MSCT were reviewed. The data acquisition, image reconstruction, quantification methods in assessment of calcium and usefulness of calcium scoring in coronary artery disease were investigated. Results MSCT with nearly isotropic volumetric imaging data, subsecond rotation and retrospective electrocardiographic gating could provide better input data for quantification of coronary arterial calcium volume. Conclusion MSCT allows more precise and repeated measurement of coronary arterial calcification with low interexamination variability.

Objective To determine the location and degree of fallopian tube obstruction,providing a safe reliable and effective treatment. Method 50 infertile women with unilateral or bilateral fallopian tube stenosis, adhesion and obstruction were selected for this study, with ages range of 23 to 38 years. Selective salpingography was performed using co-axiol catheterization with micro-guide wire mechanism combined with recanalization, anti-inflammatory agents during the procedure and postoperative period. Results The rate of properly performed catheter and recanalization reached 92% and 68.7%, respectively. During the follow-up of one year, 23 cases (23/50, 46%) obtained ability of pregnancy. Conclusion Selective salpingography with fallopian tube recanalization is a minimally invasive method to treat tubal infertility. (J Intervent Radiol, 2006, 15: 290-292)

Objective To study the diagnostic value of imageology for pyelic carcinoma.Methods The accuracy of qualitative diagnosis and sensitivity were analyzed by comparing various imaging examinations in 19 patients with pathologically proved pyelic carcinomas.Results Irregular filling defect and hydronephrosis were seen in the renal pelvis and calyces on intravenous pyelography(IVP).On CT scan,when the tumor was small,soft tissue mass was in the renal pelvis and the calyces.When the renal parenchyma involved by tumors,the soft tissue masses with unhomogeneous density,liquefaction necrosis in the renal pelvis and the parenchyma were seen.On contrast-enhanced CT scan,enhancement from slight to moderate was found in the lesion.The lesions were detected by IVP in 9/12 cases,by BUS in 10/16 cases,by CT in 18/19 cases and by MRI in 3/3 cases.Conclusion IVP and CT are the first method of choice to diagnose the pyelic carcinoma,BUS can be used as a screening method.While in evaluating the tumor involving the parenchyma of the ren or distant metastasis,CT and MRI are superior to IVP.
