Objective To explore the expression of and its clinical significance of plasma omentin-1 in coronary heart disease in central obesity. Methods Plasma omentin-1 levels were measured by enzyme linked immunosorbent assay( ELISA)in 49 central obesity participants without coronary heart disease and 67 central obesity participants with coronary heart disease,as well as 56 normal healthy individuals as control group. In addition,glucose and lipid metabolism parameter and morphological characters were assessed. Finally multivariate logistic regression analysis was used to explore the risk fact for coronary heart disease in central obesity. Results The serum plasma omentin-1 level of central obesity participants without coronary heart disease group was (45. 63 ± 9. 66)μg/L,much higher than those of people in and central obesity participants with coronary group ((30. 67 ± 6. 78 )μg/L,P ﹤0. 01 ),while lower than control group(( 53. 12 ± 7. 97 )μg/L,P ﹤ 0. 01 ) . Multivariate logistic regression analysis revealed that,age was independent risk factor of coronary heart disease in central obesity(OR=1. 176,95%CI:1. 012-1. 330,P=0. 041),while plasma omentin-1 and high density lipoprotein cholesterol were independent protective factors(OR=0. 576,95%CI:0. 254-0. 898,P=0. 000;OR=0. 466,95%CI:0. 242 -0. 690,P =000). Conclusion Detection of plasma omentin-1 level may play an important role in early diagnosis and prevention of coronary heart disease in central obesity.

AIM: To investigate the effect of single immunoglobin IL-1 receptor related protein (SIGIRR) on damage of alveolar epithelial cells in acute lung injury induced by lipopolysaccharide. METHODS: The acute alveolar epithelial cell injury model was constructed by stimulation of A549 cells with LPS. In order to over-express SIGIRR, the A549 cells were transferred with eukaryotic expression vector containing full length SIGIRR cDNA. The transcriptional activity of NF-κB was measured by dual-luciferase reporter assay system. The concentrations of IL-1β, TNF- α and IL-6 were detected by ELISA. The levels of these inflammatory factors between the transfected cells and untransfected cells were compared. RESULTS: The over-expression of SIGIRR inhibited the transcriptional activity of NF-κB. The increases in IL-1β, TNF-α and IL-6 concentrations in alveolar epithelial cells induced by LPS were observed. CONCLUSION: SIGIRR in alveolar epithelial cells inhibits TLR4 signals triggered by LPS and attenuates the inflammatory reactions in alveolar epithelial cells, which plays a protective role against the acute damage of the alveolar epithelial cells.

Objective In order to investigate the influence of reelin deficiency on the hippocampal development, the histochemical characteristics of hippocampal pyramidal cells and granule cells of reeler mice were analyzed, therefore, reelin's function would be better understood with more morphological evidences. Methods With immunofluorescent double labeling, the pyramidal cells, granule cells and mossy cells in hippocampi between wild type and reeler mice were labeled. Results The development and lamination of hippocampal cortical plate were in disorder. Pyramidal cells and granule cells dispersed, and moreover, granule cells proliferated rapidly and migrated into hilus, so that the bound between granule layer and hilus disappeared. Conclusion As a stop signal and regulatory signal, reelin plays important roles in neuronal migration of developing cortical plate, especially in the regulation of granule cell proliferation.

Objective In order to make a epileptic model in organotypic slice culture and to further investigate the epileptic pathology. Methods Immunohistochemistry, Fluoro-Jade B staining and BrdU labeling were carried out in the hippocampal slices with domoic acid treatment after 7 days of culture.Results Domoic acid could induce a series of pathological changes, such as, dispersion of granule cells(0.105±0.063) mm vs (0.057±0.012) mm, t = 4.8, P<0.01), neurogenesis in granular layer and cell loss of pyramidal cell and Mossy cell as well. Conclusions In hippocampal organotypic slices, domoic acid induced such pathological changes as human temporal lobe epilepsy and epileptic animal model. It is an ideal epileptic model for pathological, pharmacological and electronic physiological studies with great applicable prospect.

Objective To compare the surgical effects of transurethal enucleation of prostate (TUEP)with transurethal resection of prostate (TURP) by a retrospective analysis of clinical data.Methods The patients in this study were divided into the groups of TUEP (enrolled in 2010 and 2011,n =77) and TURP (enrolled in 2009,n =27) with prostate larger than 60 g and smaller than 60 g respectively.Comparisons were made between the two groups in operation time,blood loss volume and weight of resected prostate.Results In the group of patients with prostate larger than 60 g,there was no significant difference in prostate weight ((88.5 ± 9.2) g vs.(107.0 ± 15.30) g,P =0.255),operation time ((91.5 ± 8.8) min vs.(118.3 ± 20.2)min,P =0.083),and weight of resected prostate ((48.0 ± 4.6) g vs.(58.4 ± 5.4) g,P =0.32) between the TUEP (53 patients) and the TURP (12 patients) groups.There was significant difference in blood loss ((110.0 ± 16.4) ml vs.(193.3 ± 22.3) ml,P =0.011) between the two groups.In the group of patients with prostate smaller than 60 g,there was no significant difference in prostate weight ((43.1 ± 3.2) g vs.(36.8 ± 3.4) g,P =0.072),operation time ((62.7 ±6.8) min vs.(69.3 ±6.2) min,P =0.431),blood loss ((56 ± 5) ml vs.(110±20) ml,P=0.082),and weight of resected prostate ((26.3 ±2.4) g vs.(23.6 ±2.1) g,P =0.291) between the TUEP (24 patients) and the TURP (15 patients) groups.Conclusion Compared with TURP,TUEP has the advantages of less blood loss in the treatment of patients with prostate larger than 60 g.With the improvement of surgeon' s experience and development of operation techniques,TURP will be replaced by TUEP.In the treatment of patients with prostate smaller than 60 g,the operation modality can be chosen by the surgeon based on his experience and proficiency.

Objective To explore the difference between interval storage and continuous storage of dynamic imagines in contrast enhanced ultrasound (CEUS) quantitative analysis. Methods Two CEUS were performed for each of fifteen participants using interval storage and continuous storage of dynamic images. A number of parameters were analyzed including rising time (RT), time to peak (TTP), mean transit time (MTT), maximum intensity (IMAX), and area under the curve (AUC). The disk usage and time consumpation were also compared for analysis. Results There were no differences in RT, TTP, MTT, IMAX, AUC between the two groups (t=1.028, 1.012, 0.558, 0.223, 0.556, P=0.322, 0.329, 0.586, 0.826, 0.587). There was significantly positive correlations between them (r=0.989, 0.992, 0.867, 0.865, 0.947, all P<0.05). The disk usage in interval storage group was about 1/3 of that in contiunous storage group. And the interval storage method could saved 25-30 min in each case. Conclusion Interval storage is worthy for further clinical application on the groud of its disk usage sparing and less time consumpation without compromising the image quality for analysis.
