目的III期临床研究结果显示恩替卡韦(ETV)治疗48周,在组织学改善、ALT复常和hBVDNA抑制方面均优于拉米夫定(LMV);肝纤维化的改善在核苷类似物初治患者中2个治疗组相似,在拉米夫定失效患者中,ETV明显优于LMV。对基线时表现为中重度肝纤维化/硬化患者(Ishak评分:4-6)进行亚组分析,评估ETV或LMV治疗48周的疗效。方法纤维化评分是由1位病理学家对基线和48周时标本进行评估,治疗组及标本先后顺序均对他设盲。结果对hBeAg(+)核苷类似物初治的患者,48周时肝纤维化发生改善的患者比例ETV组为57%,LMV组为49%;肝纤维化没变化的患者比例ETV组35%,LMV组为28%;肝纤维化恶化的患者比例ETV组为0,LMV组为6%;对hBeAg(-)核苷类似物初治的患者,48周时肝纤维化发生改善的患者比例ETV组为59%,LMV组为53%;肝纤维化没变化的患者比例ETV组为31%,LMV组为18%;肝纤维化恶化的患者比例ETV组为2%,LMV组为5%;对hBeAg(+)LMV失效的患者,48周时肝纤维化发生改善的患者比例ETV组为43%,LMV组为33%;肝纤维化没变化的患者比例ETV组为35%,LMV组为29%;肝纤维化恶化的患者比例ETV组为0,LMV组为19%。结论接受ETV治疗的中重度肝纤维化/硬化患者比接受LMV治疗更可能获得纤维化改善或不变,这些数据与其他治疗终点(全组人群的病毒学、生化学和Knodell评价的组织学改善情况)结果一致,均为ETV优于LMV。

In 1872, George huntington presented his essay “On Chorea” to the Meigs and Mason Academy of Medicine and, in doing so, detailed a disease that would later bear his name. huntington's disease(hD) is a genetic, neurodegenerative disease that manifests as the loss of motor control,cognitive impairment,and mood and psychiatric changes in paents.

A process for purifying aqueous solutions containing heavy and toxic metals such as chromium（Cr） has been investigated. One of the extremely harmful pollutants in rivers and seawater is the heavy metal ions due to their direct impacts on human, animals and plants are hexavalent Cr（Ⅵ）. Consequently, highly sensitive sensor to detect Cr is essential. Surface plasmon resonance（SPR） technique has attracted huge research interest in detecting heavy metals specifically. In this study, three types of prism-based SPR sensor, gold（Au）/silver（Ag）, Au/polyaniline（PANI） and Au/titanium dioxide（TiO2） nanostructured films, are investigated as potential sensing material to detect the presence of Cr（Ⅵ） ions in water. The base Au layer with thickness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag, Au/PANI nanofibers and Au/TiO2sensor films, the Cr（Ⅵ） concentration is varied from 1 ppm to 15 ppm with sensitivity of 0.270 °ppm-1, 0.082 °ppm-1and 0.039 °ppm-1, respectively. Based on these results, the Au/PANI nanofibers are the most sensitive to Cr（Ⅵ） among the tested sensing materials.

Celiac disease (CD) is a disease having the characteristic pathology of the mu cosa of the small intestine. The prevalence of CD in the Turkish population has not been investigated previously. The present study was designed to determine th e prevalence of CD in healthy blood donors. Serum samples of 2000 healthy blood donors presenting to hacettepe University Faculty of Medicine hospital Blood Ban k were tested for tissue transglutaminase (tTG) IgA and IgG antibodies with enzy me-linked immunosorbent assay (ELISA; Euroimmune, Germany). The histopathologic al findings for the cases with positive serology were evaluated. The distributio n of sex was 95.7%male, and 4.3%female. The mean age was 33±9. Among 2000 don ors, 23 (1.15%) were positive for tTG IgA antibody and 3 (0.15%) were positive for tTG IgG antibody. None of the samples was positive for both antibodies. Ser um total IgA was measured in two cases with only tTG IgG positivity and was foun d to be low in one case. Twelve subjects positive for tTG agreed to endoscopy an d biopsy. histopathological examination revealed changes classified as Marsh III -II in one,Marsh II in two, Marsh I in seven, and Marsh 0 in two donors. This w as the first study conducted to determine the prevalence of tTG positivity in th e Turkish population. The tTG antibody positivity prevalence in healthy blood do nors was as high as 1.3%. This study shows that the prevalence of CD in the Tur kish population is relatively high in comparison to that in the Western world.

The effects of a harmonically exciting monopole source on an infinitely long cylindrical cavity embedded entirely within a fluid-saturated poroelastic formation of infinite extent are examined theoretically. It is assumed that the source is located outside the cavity at a specified distance from the borehole axis. The magnitudes of the hoop and radial stresses beside the pore pressures exerted on the interface and inside the porous medium surrounding the borehole are calculated and discussed. Biot's poroelastic modeling along with three types of boundary conditions for the cylindrical interface including the ideal fluid, empty borehole, and rigid inclusion with a hard boundary is employed for the analysis. Utilizing a proper translational addition theorem for expressing the incident spherical wave in terms of cylindrical wave expansions, the proposed boundary conditions at the interface are satisfied. Stresses are formulated by means of wave potential functions in a three-dimensional(3D) manner. The effects of the frequency and the radial distance between the source and borehole on the induced stresses are examined for the first cylindrical modes over frequency spectra. Two permeability conditions for the interface and three types of soils for the porous formation are considered throughout the analysis. To give an overall outline of the study, a numerical example is presented. The results clearly indicate that the distance is a key parameter and has considerable effects on the induced stress values. In addition, the interface permeability condition and soil characteristics play an important role in determining the dynamic response of the borehole. Finally,the obtained results are compared with the relevant analyses existing in the literature for some limit cases, and good agreement is achieved.
