简介:目的探讨PreS1抗原检测的临床价值。方法采用酶联免疫吸附试验法检测421例慢性乙型肝炎患者血清PreS1抗原和HBV标记物;采用荧光定量PCR法检测HBVDNA。结果在421例慢性乙型肝炎患者中,HBVDNA阳性者367例,其中PreS1Ag阳性者188例(51.2%),HBeAg阳性者119例(32.4%),后两者有显著性差异(P〈0.01);在高HBVDNA载量(105~107copies/ml和〉107copies/ml)组患者中,PreS1Ag阳性率(60.2%,60.0%)显著高于HBVDNA阴性组(33.3%)和低载量(103~105copies/ml)组(41.9%,P〈0.01);但在421例患者中,PreS1Ag阳性率(48.9%)低于HBVDNA(87.2%,P〈0.01)。结论PreS1Ag能够较HBeAg更好地反映HBV在体内的复制状态,但尚不能代替HBVDNA的检测。

简介:瞄准:在Crohn的疾病(CD)调查单核白血球的函数病人并且相关这与联系疾病的核苷酸绑定oligomerizationdomain-2(NOD2)基因变体。方法:从47个连续地提交的CD病人和9健康供血者的单核白血球与interleukin(IL)是有教养的-4和granulocyte巨噬细胞刺激殖民地的因素(GM-CSF),并且与脂肪的多糖(LPS)或muramyldipeptide(MDP)刺激了,NOD2的通常认为的ligand。结果:我们发现从CD病人的单核白血球区分了在试管内到成熟树枝状的房间(DC),由免疫显型和形态学决定了。NOD2遗传型在所有题目被估计,并且我们观察到在NOD2的不成熟、刺激LPS的DC上的高CD86表示变异CD病人,作为与wtNOD2CD病人和控制相比。由对比,导致到成熟,MDP源于变异NOD2的题目的DC的CD86表示层次比得上正常题目的那些。在耐心房间的文化的IL-12p70的数量与MDP比在在LPS治疗,然而并非术后疗法以后的控制大。结论:我们的结果建议在NOD2基因与变化从病人获得的DC显示高CD86表示描绘的激活的显型,但是当与终端相比区别分阶段执行时,有减少的回答到MDP。我们推测单核白血球的改变的区别可能导致在发炎和单核白血球的杀死的能力之间的不平衡,并且可能与CD的致病相关。
简介:目的观察内镜下高频电凝加PPI治疗岛型及舌型SSBE的近中期疗效及安全性。方法经内镜及病理检查确诊的岛型及舌型SSBE病例39例,随机及自愿结合分组。23例治疗组患者在内镜下对岛型及舌型SSBE病灶施行高频电凝治疗,同时口服雷贝拉唑,20mg,bid,疗程4周。16例对照组患者则单纯予雷贝拉唑口服,20mg,bid,持续抑酸治疗。分别于治疗后第3个月、6个月、12个月、18个月及24个月行胃镜随访,对照原内镜图片,观察各组岛型及舌型SSBE病灶的变化,并在原病灶处取活组织检查其病理改变。对治疗组中复查内镜未达显效者,再次行镜下电凝治疗并予雷贝拉唑口服,20mg,bid,疗程4周。结果治疗组随访病例平均显效率87.6%,总有效率100%;未出现出血、穿孔及食管狭窄等并发症。对照组平均显效率6.6%,平均总有效率26.5%,平均无效率73.5%。结论经内镜下高频电凝加PPI治疗岛型及舌型SSBE安全,近期疗效明显。
