Objective To explore the relationship between intrahepatic expression of interleukin-17 (IL-17) and liver fibrosis in patients with chronic hepatitis B virus infection. Methods IL-17 expressions in livers with different inflammation activity grades and hepatic fibrosis stages from patients with chronic hepatitis B virus carriers (n= 30), chronic hepatitis B (CHB, n = 55), liver cirrhosis (LC, n=20) were measured by immunohistochemistry. Serum IL-17 and liver fibrosis indices of haluronic acid (HA), laminin (LN), type Ⅲ procollagen (PC Ⅲ ) and type Ⅳ collagen ( Ⅳ C) were determined by enzyme linked immunosorbent assay (ELISA). The differences between groups were compared by Kruskal-Wallis test, and the Mann-Whitney test, and the correlation analysis was done by Spearman test. Results Intrahepatic IL-17 expression in LC group was significantly higher than CHB group (x2 =25. 3982, P=0. 004), and that in CHB group was higher than chronic hepatitis B virus carriers group (x2 = 11. 5056, P= 0. 001). The inflammation activity grade and hepatic fibrosis stage were both positively correlated with IL-17 expression (r= 0.718, 0. 693, respectively; both P<0.01). IL-17 mainly located in portal area and the expression was positively correlated with serum levels of HA, LN, PCⅢ and ⅣC (r=0. 793, 0. 834, 0. 722, 0. 883, respectively; all P<0.01).Conclusion Intrahepatic IL-17 expression is closely correlated with liver inflammation activity grade and hepatic fibrosis stage.

To report a boy with reflex seizures induced by micturition.He suffered from seizures during micturition for four yesrs.The clinical symptoms consisted of head backwards,limbs dithering,sometimes accompanying tumble.During the episodes of the seizure,his consciousness did not lose.Few seizures showed only eyes up-staring for several seconds.The livelong process of micturition was often interrupted by seizures for several times.When he finished or stoped micturition,the seizures did not occur again.His seizures could not be induced by free of micturition or other stimulative factors.The interictal EEGs showed that background asymmetry manifested as the lower amplitude and irregular rhythm in the left hemisphere,sharp or sharp and waves in right hemisphere,especially mid and back temporal.There also had sharp,spike,and spike and waves in many regions of double spheres in interictal EEGs.The other assistant check-ups were normal.while this disease was infrenquncy,it would be worthy to regard.

MicroRNAs (miRNAs) are small (approximately 22 nt) RNAs that exhibit a diversity in sequence,structure,abudance,and expression profile. Bioinformatic approaches and direct cloning methods have identified 3518 miRNAs from various species. MiRNAs play a pivotal role in the regulation of genes involved in diverse processes such as development,differentiation,and cellular growth control. Recently,many viral-encoded miRNAs have been discovered, most from the herpesviruses viral family. Virus-encoded miRNAs seem to evolve rapidly and regulate both the viral life cycle and the interaction between viruses and their hosts. The detailed study on the virus-encoded microRNAs and the role they play in the progress of viral infection,replication and expression will be beneficial to understand viral molecular biology,and also provide new strategies for the prevention and treatment of virus.

Objective To verify whether miR-630 could inhibit MDA-MB-231 cells migration and invasion by targeting Sox4 in triple-negative breast cancer(TNBC).Methods Collection normal breast tissue and breast cancer tissue from patients undergoing breast cancer resection.RT-PCR were used to test the expression of miR-630,miR-21,miR-195,miR-134,miR-200a,miR-381 and miR-1228.Western blot were used to test the expression of COL1A1,COL1 A5,MMP-2,MMP-9 and Sox4.In vitro experiment,after miR-630 was transfected into MDA-MB-231 cells,wound healing were employed to test the migratory ability of MDA-MB-231 cells,and transwell were used to test the invasion ability of MDA-MB-231 cells.Western blot were used to investigate the expressions of COL1 Al,COL1 A5,MMP-2,MMP-9 and Sox4 in MDA-MB-231 cell.Luciferase assay was used to confirmed whether Sox43'-UTR the target gene of miR-630.Results Compared with normal breast tissue,the expression of miR-630 was decreased(P<0.01),meanwhile the expression of COL1A1,COL1A5,MMP-2,MMP-9 and Sox4 were significantly increased in the triple-negative breast cancer tissue(P<0.01).In the vitro experiment,compared with the control group,the expression of COL1A1,COL1A5,MMP-2,MMP-9 and Sox4 were decreased in the miR-630 group (P<0.05);The migration activity of MDA-MB-231 cells was decreased in the miR-630 group (P<0.01);The Luciferase activity of the Sox4-3'-UTR plasmid was significantly suppressed by miR630 (P<0.05);Over expression of Sox4 could reverse the effect of miR-630 on MDA-MB-231(P<0.05,P<0.01).Conclusion In triple-negative breast cancer tissue,the expression of miR-630 decreased;miR-630 inhibits triple-negative breast cancer cells migration and invasion by targeting Sox4-3’-UTR.

ObjectiveTo observe clinical results and histopathological changes of scleral defect repaired with acellular xenogenic dermal matrix (Xeno-ADM) in rabbits.MethodsModel of rabbit sclera defect was established, and repaired with Xeno-ADM. The rabbits were clinically examined for inflammation and eyeball healing. The animals were sacrificed at 2nd and 4th week after operation, and implants were obtained and examined histopathologyically and ultrastructully with light microscopies respectively to evaluating changes of inflammation and vascularization.ResultsThere were no obvious inflammation and eyeball deformation observed. 2 weeks after implantation, the partial inflammatory cell invasion was seen with the light microscopy, and there was an obvious borderline between the Xeno-ADM and the sclera. 4 weeks after implantation, the inflammatory cells were reduced noticeably, the Xeno-ADM and the sclera completely merged with each other.ConclusionThe acellular xenogenic dermal matrix may be an ideal materix with fast neovascularization and low immunity for replace of sclera implants.

This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.

10.Gap junction and function of brain.
Journal of Zhejiang University. Medical sciences 2012;41(6):696-702
Gap junction is the aggregate of some intercellular channels, which allows ions and small molecules to transport or transfer between cells. There are about 20 proposed members of the connexin family found in mammalian tissues now, and more than 10 reported are expressed in the nervous system. The astrocytes and oligodendrocytes express some specific connexins. In the present article, we review the recent literatures to illustrate the importance of gap junction for the intercellular communication between glial cells, astrocytes and neurons, and neuronal cells, which is crucial for brain functions.
