Chemokine receptor 5 (CCR5 ),as a member of the G protein-coupled receptor(GPCR)superfamily,is a membrane protein on cell surface and one of the major of coreceptors for HIV-1infection.CCR5 has became a molecular target for the novel drugs against HIV-1,and antagonists for CCR5 could be grouped as following, chemokine derivatives,small molecule non-peptide compounds,molecular antibodies and peptides. These compounds with high anti-viral activity and affinity are at different stages, and some have been under clinical studies. Therefore, the development research in the different kind of CCR5 antagonists is reviewed.

Objective To investigate the effect and the underlying mechanism of miRNA (miR)-506 regulating transforming growth factor-β1 (TGF-β1)-induced endothelial-mesenchymal transition of human aortic endothelial cell lysates.Methods In this study,miR-506 and inhibitory members of the ASPP family (iASPP) were selected as the study objects.First,the expression of miR-506 in human aortic endothelial cell lysates (HAEC) lysate was detected under different concentrations of TGF-β1.The expression of platelet endothelial cell adhesion molecule-1 (CD31),endothelium-cadherin (VE-cadherin),fibroblastspecific protein-1 (FSP1),α-smooth muscle actin (α-SMA) and N-cadherin was determined after miR-506 mimics/mimic negative control (NC) transfection into HAEC treated with or without TGF-β1.Then the expression levels of iASPP in miRNA-506 mimics/mimic NC-transfected HAECs treated with or without TGF-β1 were determined.Finally,the protein expression of CD31,VE-cadherin,FSP1 and α-SMA in HAEC transfected with miR-506 mimics/mimic NC was determined after iASPP overexpression.Results TGF-β1 can induce human aortic endothelial cell mesenchymal transition,down-regulate CD31 and VE-cadherin expression while up-regulate FSP1,α-SMA and N-cadherin expression;TGF-β1 inhibited miR-506 expression,promoted iASPP expression;miR-506 transfection into HAECs up-regulated CD31 and VE-cadherin expression while up-regulate FSP1,α-SMA and N-cadherin expression;miR-506 could downregulate the expression of iASPP;the overexpression of iASPP increased the expression of FSP1,α-SMA and N-cadherin,down-regulated CD31 and VE-cadherin and promoted the transformation of human aortic endothelial cells.Conclusions The transfection of iASPP plasmid promoted the endothelial-mesenchymal transition of human aortic endothelial cell lysates.The transfection of miR-506 inhibited the expression of iASPP and inhibited the endothelial-mesenchymal transition of human aortic endothelial cell lysates induced by TGF-β1.

To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

Objective To investigate the value of thyroid transcription factor-1(TTF-1) in the diagnosis and biological behavior assessment of hepatocellular carcinoma (HCC). Methods Thirty liver specimens obtained from benign lesions were analysed, among which 25 were hepatic cirrhosis and inflammatory diseases, and the other 5 were adenomas. And there were 176 specimens of liver tumors, among which 142 were HCC (well differentiated, n=12; moderately differentiated, n=57; poorly differentiated, n=73), 17 were intrahepatic cholangiocellular carcinoma (ICC) and the other 17 were liver metastatic carcinoma (MC). The expression of TTF-1 was examined immunohistochemically in the above tissues, and the difference in expression of TTF-1 among different tissues was examined by Fisher's exact test, Kruskal-Wallis test and Spearman rank correlation analysis. Results TTF-1 was significantly expressed in the cytoplasms of all the hepatocytes besides tumors and liver benign lesions. The expression rate of TTF-1 in HCC was 78.9% (112/142), however, TTF-1 was negatively expressed in ICC and MC(P

Objective To examine the relationship of heparanase expression and age, clinicopathological features and prognosis of ovarian cancer patients. Methods Forty-one ovarian cancer specimens, from the patients admitted to the 3 hospitals of our university during the period of Jan 2003 to Nov 2005, were of serous carcinoma (22 cases) and mucous carcinoma (10 cases) and other types (9 cases), of which 16 were well and moderately differentiated and 25 poorly differentiated. Ten specimens of normal ovarian tissues were taken as normal controls. The heparanase expression was detected in all specimens and its relationship with histologic type, differentiation, FIGO stage and prognosis of the ovarian cancer was analyzed. Results The positive rate of heparanase expression was 80.48% in ovarian cancer tissues and 10.00% in normal ovarian tissues (P

Objective:To investigate regulatory immune response induced by DNA vaccination encoding T cell receptor V?5.2 or V?2.1 chain predominantly displayed on ovalbumin (OVA)-specific T cell clone.Methods:BALB/C mice were vaccinated with pcDNA3.1 encoding T cell receptor (TCR) V?5.2 or V?2.1 chain respectively.Using RT-PCR,transcription of the recombined plasmids was analysed. Cell proliferation was measured by 3H-TdR incorporation.CTL response was assayed by JAM test.Immuno-fluorescent assay was used to examine the anti-TCR antibody level and the number V?2 +T cells.Results:RT-PCR analysis showed that the recombined plasmids can be transcripted in vivo and in vitro.DNA vaccine with TCR variable chain effectively induced TCR-specific humoral and cellular immune response,V?2 +T cells was not depleted by V?2.1 TCR-DNA vaccination,but rather was anergy.Conclusion:Regulatory immune response can be induced by DNA vaccination encoding TCR V? or V? region in normal mice.

OBJECTIVE:To learn the application and tendency of hepatoprotective drugs in a third grade class A hospital dur-ing 2011-2014,and to provide reference for rational drug use. METHODS:DDDs analysis and consumption ordering method were adopted to analyze the change of DDDs,DDC and other index of hepatoprotective drugs in this hospital from 2011 to 2014. RE-SULTS:2011-2014,the amount and DDDs of Hepatoprotective injection in this hospital increased year by year,while oral dosage form decreased year by year. DDC order of each drug kept stable during 2011-2014;DDC and DDDs of drugs for promoting ener-gy metabolism were all in high level,and ornithine aspartate and ademetionine always took up the first 2 places in 4 years. Polyene phosphatidylcholine and Reduced glutathione injection were cheap,but had higher DDDs. Except Glutathione tablet,DUI of other hepatoprotective drugs had no great difference in 3 years,and fluctuated in 2014;hepatoprotective drugs with DUI>1 and DUI<1 occupied a large proportion. From 2010 to 2014,compared with previous year,the drugs with consumption sum/DDDs ratio num-ber close to 1 reduced significantly in the next year,decreasing year by year. CONCLUSIONS:In this hospital,injections are used too frequently,and overuse of drugs for promoting energy metabolism exist. Polyene phosphatidylcholine and Reduced glutathione injection can be used as a valuable drug in the clinic,and their cost are more acceptable,but not in excess.
