Objective To investigate the effect of CKLF-like MARVEL transmembrane domain contai-ning member 5(CMTM 5)on EG-VEGF expression in prostate cancer cells , and to detect the potential mechanism of CMTM5 inhibiting prostate cancer .Methods The relative expression of CMTM 5 and EG-VEGF in prostate cells and prostate cancer cells was detected .Prostate cancer cells were given Plasmid transfection to overexpress CMTM5 and EG-VEGF expression was again detected .Then CMTM5 and EG-VEGF were compared between be-fore and after CMTM5 plasmid transfecting prostate cancer cells .Results Compared with the relative expresion of EG-VEGF and CMTM5 in prostate cells , prostate cancer cells showed high expression of EG-VEGF and low ex-pression of CMTM5, which were statistically significant , P<0.05.Compared with prostate cancer cells , the rela-tive expression of CMTM5 were obviously upregulated and EG-VEGF obviously decreased in prostate cancer cell after transfected by CMTM5 plasmid, which were statistically significant , P<0.05.Conclusions Prostate canc-er cells shows higher EG-VEGF expression and lower CMTM 5 campared with normal prostate cells .EG-VEGF is suppressed significantly when the prostate cancer cell is transfected by CMTM 5 plasmid and shows highlevel of CMTM5 expression , suggesting high expression of CMTM 5 may inhibit the development of prostate cancer by downregulating EG-VEGF expression .

In recent years, the cases of prenatal paternity testing gradually increased in forensic practice. The traditional prenatal paternity analysis can be performed only after invasive sampling of chorionic villi or amniotic fluid, which can result in a risk of miscarriage. The existence of circulating cell-free fetal nucleic acid in maternal plasma has brought new opportunities for the noninvasive prenatal paternity testing. In this paper, the research situation and application prospect of circulating cell-free fetal nucleic acid in maternal plasma in prenatal paternity testing are reviewed.

Objective To explore the mechanism of Exenatide-induced rat pancreatic tissue lesion.Methods Thirty SD male rats were divided into three groups according to complete random design,and each group had 10 rats,namely Exenatide group,diabetes-model group and control group.Diabetes-model rats were induced by streptozotocin (STZ,35mg/kg) and high-sugar and high-fat diet.The Exenatide group and diabetes group were subcutaneously administered with Exenatide at a dose of 5 μg/kg twice a day.The control group was treated with same amount of saline.Ten weeks later,all the rats were sacrificed and the pancreatic tissues were harvested for routine pathological examination.Immunohistochemical method was used to detect the expression of α-smooth muscle actin (α-SMA) and type Ⅲ collagen protein in pancreatic tissue,and ELISA was applied to measure the expression of matrix metalloprotei-nase-2 (MMP-2) and MMP-9 in pancreatic tissue.Results In control group,there was no pathological change in pancreatic tissue.In Exenatide group,chronic inflammatory changes were observed; and the degree of inflammatory changes were much severe in diabetes group,and the pathological scores were gradually increased in the 3 groups (P ＜0.05).The expressions of MMP 2 in pancreatic tissue in control group,Exenatide group,diabetes group were (186.98 ± 23.24),(306.07 ± 59.82),(365.08 ± 89.55) μg/L,and the expressions of MMP-9 were (49.37 ± 7.08),(67.24 ±14.73),(87.37 ±13.39)μg/L.The values were significantly higher in Exenatide group and diabetes group than those in control group (P ＜ 0.05),but the difference between the two groups was not statistically significant.The numbers of α-SMA positive cells per high power field were (13.4 ± 5.97),(29.5 ± 8.80),(79.3 ± 27.23) in control group,Exenatide group,diabetes group,and the numbers of type Ⅲ collagen positive cells were (10.6 ± 4.93),(29.3 ± 12.95),(56.0 ± 27.21).The values were significantly higher in Exenatide group than those in control group,and the values were significantly higher in diabetes group than those in Exenatide group (P ＜ 0.05).Conclusions Long-term subcutaneous injection of Exenatide may activate pancreatic stellate cells and cause expression of α-SMA,Ⅲ collagen protein,and MMP-2,MMP-9,then induce chronic inflammatory changes.

AIM:To study the effect of posterior sub - Tenon's capsule injection of triamcinolone acetonide ( TA ) in treatment of patients with diffuse diabetic macular edema ( DME) before panretinal photocoagulation ( PRP) .
METHODS:Retrospective analysis of the clinical data of 96 cases (96 eyes) with DME treated in our hospital from October 2008 to May 2012, and the patients were divided into the study group and control group, each group with 48 cases ( 48 eyes ) , the control group were only treated with PRP, and for the study group, TA was injected one week before PRP. At 6mo after treatment, best-corrected visual acuity ( BCVA) and retinal thickness changes of two groups were compared, the changes of intraocular pressure in two groups was analyzed.
RESULTS:After treatment, two groups were followed up for 6mo, compared with before treatment, the expression of BCVA in control group was reduced, and rise in the study group, with significant difference between the two groups (P<0. 05), and during the follow-up period, IOP change was in the normal range for the two groups, with no the difference (P>0. 05), the study group had foveal thickness reduction of 9. 6μm, the control group was increased by 31. 9μm, with significant difference (P<0. 05), parafoveal thickness in the study group decreased 5μm, significantly increased 22. 1μm in the study group, centre concave surrounding thickness increased 0. 4μm in study group and 19. 4μm for the control group, with no significant difference (P>0. 05).CONCLUSION:TA injection in patients with diffuse DME before PRP is safe and effective, and it is superior to simple PRP therapy, and it can be applied in primary hospital.

Differential gene expression profiles in Balb/cJ mouse model of acute hepatic failure infected with MHV-3 virus intervened by anti-hepatic failure compound (AHFC) and the changes of cytokines regulated by genes were investigated. The Balb/cj mice were divided into AHFC-intervened group and control group randomly. Acute hepatic failure model of Balb/cJ mice infected with MHV-3 virus was established. The survival rate in the two groups was observed. It was found that the survival rate in the AHFC-intervened group and control group was 90% and 50% respectively 48 h after intraperitoneal injection of MHV-3 (P<0.05). Before and after the experiment, the cytokines in peripheral blood of the survival mice were determined, and RNA was extracted from survival mouse liver tissue for the analysis of the differential gene expression by a 36 kb mouse oligonucleotide DNA array. In all the genes of microarray there were 332 genes expressed differently in the two groups, in which 234 genes were up-regulated and 78 genes down-regulated. Through clustering analysis, the differential expression of immune related genes, including TNF receptor superfamily, Kctd9, Bcl-2, Fgl2, IL-8, IL-6, IFN-gamma, TNF-alpha etc. might be related with the curative effectiveness of AHFC. It was suggested that AHFC can balance the immune state of mouse model of acute hepatic failure infected with MHV-3 virus mainly through regulating the expression of immune related genes, decrease the immune damage and inhibit liver cell apoptosis of mouse acute hepatic failure model obviously so as to increase the survival rate of mouse models of acute hepatic failure.

Objective To elucidate significance of hyperintense vessel signs(HVS)on FLAIR MRI in patients with cerebral infarction. Methods Two hundred and sixty-two patients with cerebral infarction admitted in our hospital were included in this study. We retrospectively defined HVS on FLAIR MRI in these patients in comparison with time of flight(TOF)on MR angiograms(MRA), hyperintense lesions on diffusion-weighted images(DWI). Results HVS on FLAIR MR[were identified in 117 patients with cerebral infarction(45.4%), of which 47 patients(83.9%)were obtained within 24 hours of symptom onset. HVS on FLAIR MRI were detected in 74 patients at sylvian fissure(62.2%), 11 at cortical sulci (9.2% ,11/119),34 at the posterior circulation regions(28.6% ,34/119). HVS on FLAIR MRI coincided well with ischemia of TOF on MRA and lesion patterns on DWI (χ2 test,P<0.01, respectively). Conclusion HVS on FLAIR MRI is helpful to evaluate abnormal major cerebral arteries of patients with cerebral infarction.
