简介:瞄准:检验在试验性的严重尖锐胰腺炎(树液)抵销抗体的反高的活动性组盒子1的效果(HMGB1)。方法:傻瓜被在C3H/HeN老鼠创造关上的十二指肠的循环劝诱。傻瓜在抵销抗体(200大杯)的anti-HMGB1的intraperitonealinjection以后立即被劝诱。胰腺炎,机关损害(肝,肾和肺),和到胰的细菌的translocation的严厉被检验在树液的正式就职以后的12h。结果:显著地抵销抗体的Anti-HMGB1在树液改进了浆液淀粉酶水平的举起和胰和肺的组织学的改变。Anti-HMGB1抗体显著地也改善了在SAP.However的浆液丙氨酸aminotransferase和creatinine的举起,anti-HMGB1抗体变得更坏细菌的translocation到胰。结论:BlockadeofHMGB1稀释了树液的发展并且联系了机关机能障碍,建议HMGB1may充当为在树液的煽动性的反应和机关损害的一个关键调停人。
简介:病人男性,46岁,左上腹部疼痛不适、消瘦1月,于2002年1月20日入院。病人自述1个月前开始左上腹部隐痛不适,呈持续性疼痛,夜间加重,伴有乏力,体重下降明显(约10kg)。无其它不适。查体:未触及表浅淋巴结肿大。腹部膨隆,以左侧为主。可触及脾脏肿大,脾下界达左肋下约3cm。向右越过中线2cm,质韧,边界清,触痛明显,推之不移动。B超:肝脏正常。脾脏体积显著增大,30cm×28cm×15cm大小,
简介:目的观察早期胃癌组织中GTP酶激活蛋白SH3功能区结合蛋白G3BP1和G3BP2的表达变化并探讨其意义。方法选择早期胃癌组织89例和正常对照组织35例,采用免疫组织化学方法检测两组G3BP1蛋白和G3BP2蛋白的表达情况。结果早期胃癌组和正常组G3BP1的阳性率分别为87.64%和60.00%,G3BP2阳性率分别为86.51%和54.28%,两组比较差异有统计学意义(P=0.000,0.000);早期胃癌G3BP1和G3BP2的表达均与幽门螺杆菌感染相关(P=0.000);早期胃癌组织中G3BP1与G3BP2表达呈正相关(rs=0.252,P=0.017)。结论早期胃癌组织中G3BP1和G3BP2呈高表达,可能与幽门螺杆菌感染紧密相关,两指标异常表达可能在早期胃癌的发生和发展中起重要作用。
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。
