Objective To discuss the role of dendritic cells (DCs) in cellular immunity pathogenesis of glomerulonephritls (GN). Methods 114 patients with GN were selected randomly and divided into two groups,primary GN (pGN) and secondry GN (sGN). CDIa^ , CD3^ and CD8^ cells in bioptic renal tissues were examine dy immunohistochemically. The distribution of CDla cells and the infiltration of CD3^ and CD8^ cells in renal tissues were observed. Results There was no significant difference of CDIa^ , CD3^ , and CD8^ cells between pGN and sGN group (P>0. 05). CDIa^ cells had significant positive correlation with the infiltrative CD3^ and CD8 cells,respectively (P<0.01). The infiltrative CD3^ cells had significant positive correlation with the CD8 cells in the same area, respectively (P<0.01). CD1a^ cells, CD3^ cells infiltrating in both glomeruli and renal interstitial tissues, and CD8^ cells only infiltrating in renal interstitial tissues, all of them had significant positive correlation with the degree of glomerular proliferation, respectively (P<0.05). The infiltrative CD3^ and CD8^ cells in renal interstitial tissues had significant positive correlation with the degree of glomerular sclerosis and the lesion degree of renal tubule and interstitial, respectively (P~ 0. 05). There were significant positive correlation between CDla cells and the lesion degree of renal interstitial (P<0.05). Collusion DCs could activate T lymphocyte by presenting antigen, then the activated T lymphocyte participate in the pathogenesls of GN through releasing cytokine and/or directly damaging the renal tubule and interstitial, which produce more serious glomeralar lesion.  相似文献

本文讨论了80例脑梗塞磁共振成像与临床表现,其中20例有CT检查。多数病例磁共振成像显示为多发性脑梗塞(95%)。梗塞灶在T_1加权是低信号改变;T_2加权呈高信号改变,急性和慢性期特点一致。资料结果表明:磁共振成像定位准确(98.75%)。病灶检出T_2比T_1敏感,磁共振成像检出病灶多于CT。在诊断脑梗塞方面,磁共振成像优于CT。  相似文献

本文报道了75例健康儿童和75例克山病患儿心导纳微分图的改变。亚急型、慢型克山病患儿的每搏量、心搏指数、心搏功指数、每分心输出量、心指数、心功指数及血管顺度均比健康儿童明显下降(p<0.02~p<0.001),而总外周阻力明显增高(p<0.01~p<0.001)。上述所有参数在潜在型病例同健康儿童比较无明显差异(p>0.05)。  相似文献

应用计算机辅助诊断心脏病:房间隔缺损、室间隔缺损、动脉导管未闭、二尖瓣狭窄4种,共350例.本诊断方法,以此4种心脏病概率评分矩阵为依据,矩阵的归纳以贝叶斯定理(BAYE'S THEOREM)为基础。研究资料来源于临床术后病例。通过设计和程序的实践,证明此诊断符合率高于术前,其正确率达100%.为诊断心脏病,提供重要手段,可推广应用.  相似文献

对27例脑肿瘤患者手术前后免疫功能进行了检测。结果血清IgG、IgA和IgM的改变与正常组相比,手术前后均无明显差异(P>0.05);淋巴细胞亚群较正常组降低极为明显(P<0.001),肿瘤切除术后细胞免疫功能有所恢复,但与术前比较无明显差异(P>0.05),且仍显著低于正常状态(P<0.01)。说明脑肿瘤病人体液免疫无变化,细胞免疫功能则明显低下,且肿瘤切除术后其细胞免疫功能尚难很快恢复到正常状态。  相似文献

对74例肺癌和76例良性肺病患者进行了血清及支气管肺泡灌洗液(BALF)中超氧化物歧化酶(SOD)和溶菌酶(LZM)的测定,结果表明:①肺癌患者血清及BALF中SOD水平明显降低,以癌患侧BALF中SOD降低最明显,阳性率为71.8%。腺癌较鳞癌及小细胞癌低,周围性肺癌较中央型低,Ⅲ、Ⅳ期较Ⅰ、Ⅱ期低。②肺癌患者血清及BALF中LZM水平降低,阳性率为46.3%和59.7%。小细胞癌降低最明显,晚期肺癌较早期更低。③SOD和LZM联合检测诊断肺癌的价值明显优于单项指标检测,其敏感性、特异性分别高达87.8%和89.5%。提示:通过血清及BALF中SOD和LZM联合检测对肺癌早期诊断、病理分型及预后判断有一定意义。  相似文献

对28例恶性滋养细胞肿瘤肺转移患者血和脑脊液HCG值进行了测定。7例发生中枢神经系统转移(脑转移5例,脊髓转移2例)。转移组与无转移组之脑脊液HCG值、血和脑脊液hcG比值,均有显著差异(P<0.001,P<0.05)。脑转移病例血和脑脊液比值最高为38:1。证明血和脑脊液HCG比值可作为判断有无中枢神经系统转移的敏感指标,对高危患者筛选的依据。  相似文献
