Objective To evaluate the role of interleukin-4 receptor (IL-4R) in renal fibrosis following renal ischemia-reperfusion (I/R) injury in mice.Methods Twelve male wild type BALB/C mice and 12 IL-4Rα gene-knockout mice,aged 8-10 weeks,weighing 20-30 g,were used in the study.The mice of either type were divided into 2 groups (n =6 each) using a random number table:sham operation group (group S) and group I/R.In group I/R,renal I/R was induced by occlusion of the right renal artery for 1 h with atraumatic microclips followed by 2 weeks of reperfusion.The right renal artery was only isolated in group S.At 2 weeks of reperfusion,blood samples were taken from the orbital vein for determination of the concentrations of serum blood urea nitrogen (BUN) and creatinine (Cr).The renal tissues were obtained,and the renal fibrosis area was measured by Sirius Red staining.The expression of fibronectin (FN),collagen Ⅰ (COL-Ⅰ) and α-smooth muscle actin (α-SMA) in renal tissues was detected by immunofluorescence.The expression of signal transducer and activator of transcription 6 (STAT6) and phospho-STAT6 in renal tissues was determined by Western blot.The ratio of phoshop-STAT6 to STAT6 was calculated to reflect the phosphorylation of STAT6.Results Compared with group S of wild type mice,the serum BUN and Cr concentrations and renal fibrosis area were significantly increased,the expression of FN,COL-Ⅰ and α-SMA in renal tissues was significantly up-regulated,and the phosphorylation of STAT6 in renal tissues was significantly increased in group I/R of wild type and IL-4Rα KO mice (P＜0.05).Compared with group I/R of wild type mice,the serum BUN and Cr concentrations and renal fibrosis area were significantly decreased,the expression of FN,COL-Ⅰ and α-SMA in renal tissues was significantly down-regulated,and the phosphorylation of STAT6 in renal tissues was significantly decreased in group I/R of IL-4RαKO mice (P＜0.05).Conclusion The mechanism of renal fibrosis following renal I/R injury is partially related to IL-4R,and IL-4R results in renal fibrosis through promoting activation of STAT6 signaling pathway in mice.

Objective To evaluate the value and the significance of 16-slice spiral computed tomography angiography(MSCTA) in identifying the vertebral artery course variation.Methods MSCTA data in 22 patients with anomalous path of vertebral artery were retrospectively analyzed,13 of them had undergone DSA examinations,and 5 of them had also undergone MRI examinations.Multi-planar reconstruction(MPR),curved MPR,thin-slab maximum intensity projection(MIP),volume rendering(VR) or slab VR(cut-plane VR) were used to assess the anomalous path of the vertebral artery and its relationship with the adjacent large vessels.Virtual endoscopy(VE) was used to evaluate the orifice of the vertebral arteries and its relationship with the aortic arch and the ostia of the adjacent large vessels.Different views of vertebral artery were analyzed on DSA.MSCTA and DSA images were analyzed in blinded fashion for the accuracy of anomalous vertebral artery path and origin detection.Results were compared in a secondary consensus evaluation.Results The anomalous path of the vertebral artery in all 22 patients were correctly displayed on MSCTA,7 of them had anomalous origin of vertebral artery,the anomalous of ostia showed clearly.The vertebral arteriae with course variation were all going up at the front of the foramen transversarium of C6,then bended into the C5,C4 or C3 foramen transversarium.DSA could only be detected the anomalous origin in 13 patients undergone DAS.5 patients indirectly showed having course variation of vertebral artery by MRI.Conclusion MSCTA is superior to DSA in showing the anomalous path and orifice of vertebral artery,it should be considered as a non-invasive imaging tool for these diseases.

In order to study the pathogenesis of HPVl1 and seek for a therapeutic approach of the disease caused by HPV1l. The HPVl1/E2 644bp was amplified by PCR with HPVll plasmid DNA. pGEM-T Easy was used as vector and a clone pTV-644 was obtained.The inserted DNA sequencing was carried out after selecting and identification. According to the hammerhead structure described by Symon's, the possible secondery cleavage sites on HPVll/E2 mRNA were analyzed and the secondery structure of substrate was predicted by computer and ribozyme, excluding analogous sequence of substrate combined with ribozyme were found in the mRNA.The hammerhead ribozyme of RZ2777 against HPV1l/E2 mRNA was seleted to carry out cleavage reaction in vitro. Results of the experiment showed that 644bp substrate derived from HPVll/E2 can be cleavaed site-specifically by ribozyme in vitro. The cleavage activity showed over 85% by choosing the optimun reaction condition, which was not affected by two cis-ribozymes on both 3′-and 5′-ends released by self cleavage,but two flan-king sequences of target RNA influenced the cleavage activity. Results demonstrated that the ribozyme will become a highly effective and specific therapy against HPVll infection.
