Comparing with control group, CD4~+ T cells of AIDS patient were markedly depleted in gastro-mucosal tissues(P＜0.01), but in presymptomatic patients CD4~+ T cells were not significantly different. CD3~+ T cells, CD8~+ T cells and NK. cells were notably increased (P.01), and they severely infiltrated glands and epitheliums in gastro-mucosal tissues. And the quantity and distribution of CD20~+ B cells between patients and control group were not obviously different.

将47例初发性膀胱癌术后患者分为A(23例)和B(24例)二组，同时将52例复发性膀胱癌术后患者分为C(26例)和D(26例)二组。A、C组在术后6h内表阿霉素80mg/次单次灌注；B、D组在术后1周内表阿霉素50mg/次膀胱灌注，每周1次，共4次，后每月1次，共1年。

Results After seven days of culture, some BMSCs appeared typical morphological neuronal traits. Cell bodies appeared refractile, cone-like or spherical with long processes, NSE was expressed. Animals in group A and group B recovered their motor functions in a varing degree, the difference of BBB score was significant (P.05). Hematoxylin and eosin staining demonstrated that the lesion areas of the spinal cord in group A recovered better.

结果 诱导7d后有部分细胞具备神经元样细胞形态，胞体呈锥形或圆形，有较长单极或多极的突起，有NSE阳性细胞表达；细胞移植后1~5周，A、B组动物运动功能均有不同程度恢复，但B组恢复较慢，BBB评分差异有统计学意义(P.05)；组织形态学观察示A组损伤脊髓恢复较好。
