AIM and METHODS: To analysis the factor that involved in renal carcin ogenesis, we used the bait gene AK001518 to screen GenBank. To understand the re lationship between cell cycle related gene(CCRG) and p15, we did RT-PCR and Nort hern Blot experiments. Th en we examined CCRG expression level in renal carcinogenesis. RESULTS: Gained a function unknown gene CCRG that was 67% a mino acid identical with the gene AK00 1 518 that was regulated by p15. It was shown that the CCRG mRNA was dramatically d ecreased when p15 gene was over-expressed. CCRG expression level was much higher i n tumor tissues and cells than normal tissues and cells. CONCLUSION: The novel g ene CCRG expressed highly in the renal carcinoma, which might play a significant role in the renal carcinogenesis.

Objective To discuss the emergency interventional therapy for ureter invasion by CACX, obstructive bilateral hydronephrosis and uremia complicated with hemorrhoea. Methods 5 cases with ureter invasion by CACX, obstructive bilateral hydronephrosis and uremia suffered from hemorrhoea during hemodialysis, who were performed with emergency interventional therapy. Results After therapy, hemostasis were realized in all cases, and all symptoms were alleviated, such as vaginal fluid and fall-swell in pelvis. The short-term total effective rate was 100% . Conclusion Interventional chemoembolization can be used in the treatment of CACX with acute hemorrhoea.

Objective To study the continuous drainage treatment by percutaneous puncture of Splenic Abscess (SA), which is due to double-embolization for treatment of liver cancer with hypersplenism. Methods 158 patients with liver cancer with hypersplenism were adopted as the subjects, of which, 7 ones were complicated with SA. Results The symptoms of the 7 ones were all alleviated, such as fever, abdominal pain, left interior pain. Conclusion Continuous drainage treatment by percutaneous puncture, combined with flushing abscess cavity by antibiotics solution, is very effective for SA due to double-embolization.

Objective:Based on relevant database data analysis,to explore the correlation of the abnormal expression of EMT related factors and chronic obstructive pulmonary disease and its related non-small cell lung cancer.Methods: Based on some data sets of GEO in the NCBI database,to perform express analysis,survival analysis and correlation analysis.Results: ①Snai1 and other EMT related regulatory factors exist significantly higher expression in non-small cell lung cancer patients,and E-cadherin (CDH1) was showed significantly lower expression. ②A large number of COPD patients samples were analyzed,and some EMT-related molecules in patients with COPD also showed significant abnormal expression and consistented with the changes in patients with non-small cell lung cancer.Conclusion: The results showed that dysregulation expression of EMT related regulatory factors may have some correlation with disease progression of COPD patients through the EMT markers and their expression and correlation analysis in COPD patients.

Objective To evaluate angiography and interventional embolization in diagnosis and treatment of massive hemobilia.Methods During 10 years,9 patients with massive hemobilia underwent emergency selective hepatic artery angiography to find the bleeding points,and then embolized the feeding branches.Results All cases demonstrated clearly on angiography about the arterial hemorrhage,and extravasation of contrast-medium.Hemorrhage was stanched immediately after embolization of the feeding branches of the hepatic artery.Conclusion Selective hepatic angiography and interventional embolization for massive hemobilia is a safe and efficient diagnostic and therapeutic method.(J Intervent Radiol,2006,15:213-214)

Objective To investigate the protective effects of ethanol-extract of Halenia elliptica D. Don on chemical hepatic injury in mice. Methods Mouse models of chemical hepatic injury were induced by intraperitoneal injection of 0.12 %CCL4. Extract of Halenia elliptica D. Don by alcohol was administered,and serum ALT,AST activities and liver glycogen level were measured in mice. Results Compared with the models,the enzyme activities of ALT and AST were significantly reduced and the content of liver glycogen was significantly increased in the ethanol-ex tract of Halenia elliptica groups. Conclusion It is indicated that ethanol-extract of Halenia elliptica D. Don has an effect in protecting the liver.

[Objective] Based on the resting state functional magnetic resonance imaging to investigate the abnormal features of the functional connectivity of resting brain neural network in the patients with primary insomnia,by using voxel-wise whole-brain finctional networks analysis of degree centrality (DC) for imaging evidence of neural mechanisms underlying primary insomnia.[Methods] The resting state fMRI were performed in 59 PI patients and 47 age,education,and sex-matched normal healthy subjects.Analysis of DC map changes between the two patient groups and the control group were performed by two sample t test.(threshold at P ＜ 0.05).[Results] Compared with the control group,the patients with PI showed significantly reduced DC value in bilateral medial frontal gyrus (MFG),bilateral anterior cingulate gyrus (ACG),and right insula;and increased DC value in right middle temporal gyrus (MTG),and left cuneus,(CUN),P ＜ 0.05.[Conclusion]Changes of DC value occurred in some region of brain in the P[patient groups when compared with the control group.It was indicated that DC,as a novel resting-state fMRI parameter in the voxel-wise whole-brain functional networks,might be an appealing alternative approach for further study on pathologic and neuropsychological states of PI.

Objective To assess the application value of NCE-MRA using iMSDE prepared bSSFP sequence in lower limb in patients with diabetes. Methods This prospective study included a total of 35 patients with type II diabetes who underwent CE-MRA on the 1.5T MR scanner after the NCE-MRA. The obtained MIP images were independently rated by two radiologist with a four score table and using CE-MRA as a reference standard to evaluate the diagnostic accuracy of NCE-MRA for the narrowed arteries. The difference of the percent age of diagnostic arterial segments between NCE-MRA and CE-MRA on diabetic patients was evaluated by the χ2 test. Results Compared with CE-MRA, the diagnostic-value arterial segment ratio of pelvic arteries on NCE-MRA is decreased significantly. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of two readers in NCE-MRA were 95%/87%, 96%/95%, 57%/72%, 99%/99%, and 96%/95%(k=0.76), respectively. Conclusions The NCE-MRA using iMSDE prepared bSSFP sequence is capable of depicting vascu-lar lesions for the lower extremities in diabetic patients with the advantages of contrast agent free, short scan times and good diagnostic value in the thigh and calves.

Objective To investigate the effects of a proliferation-inducing ligand(APRIL) on migration and invasion of colorectal cancer (CRC) and matrix metalloproteinases (MMPs) expression in order to observe the role of APRIL in CRC metastasis.Methods The siRNA plasmid vector targeting APRIL gene (siRNA-APRIL) was transfected into SW480 cells and recombinant human APRIL(rhAPRIL) was used to stimulate HCT-116 cells.Tumor cell migration and invasion were measured by Transwell chambers.RT-PCR and ELISA were applied to examine the expression level of MMPs.Results Metastatic and invasive capacities of siRNA-APRIL transfected SW480 were significantly inhibited,and these capacities of APRIL stimulated HCT-116 cells were significantly enhanced compared with their respective controls( all P＜0.05 ),accompanied with the alterations of MMPs mRNA and secreted protein expression( P＜0.05).The number of invading cells of SW480 control and rhAPRIL stimulated HCT-116 was significantly decreased by a MMP inhibitor GM6001 ( P＜0.05 ).Conclusion APRIL facilitates migration and invasion of CRC via regulation of MMPs,which suggests that APRIL might be used as a new target for the intervention and treatment of CRC metastasis.
