2003年以来图书馆员素质问题研究述评

The secondary CM symptom included dry mouth and inclining of drink, disliking of hot and liking of cold, polyorexia, anergia knees and loin, dizziness and tinnitus, burning sensation of five centers, halitosis, dry stool and yellowish or reddish urine.

次症指标选择口干喜饮、恶热喜冷、消谷善饥、腰膝酸软、头晕耳鸣、五心烦热、口臭、便结、尿黄。

In vivo, faint responsiveness of anergic T cells induced by SEA injections at 3 days interval and at 28 days interval could be seen respectively after 21 days and 28 days.

在体内，间隔3天组和间隔28天组中诱导的无能T细胞分别从末次注射后第21天和第28天开始出现较弱的应答反应。

The anergic state of T cells was not limited by doses of SEA and there were other causes on anergic state of T cells excepting IL-2.

T细胞无反应性不受SEA剂量限制，T细胞受抗原刺激不能产生IL-2不是无能状态产生的唯一原因。

Conclusion: The activation and proliferation of naive T cells could be induced by SEA singly, and the T cells became anergic by repeated SEA induction in vitro.

结论：SEA初次诱导小鼠脾淋巴细胞时，能显著促进T细胞的活化和增殖；经SEA多次刺激（3次）可诱导T细胞的无反应性。

The ability of anergic cells to respond to antigen and/ or exogenous recombinant mouse interleukin-2 ( rmIL-2) was tested.

无能细胞中加入刺激抗原或重组小鼠IL-2（rmIL-2），观察无能细胞的反应情况。

These results suggest that ability of proliferation of CD4+ T cell gradually decrease which restrain the response to the second stimulation and is in anergic state.

结论：CD4~+T细胞在SEB刺激后虽有增埴，但增殖后的CD4~+T细胞的增殖能力逐渐下降，对二次抗原刺激增殖受抑，即处于无能状态；

As professional type 1 interferon-producing cells, Pre-DC2 have a capacity to induce an anergic state in human T cell lines.

作为体内主要的Ⅰ型干扰素（IFN）分泌细胞，Pre-DC2还具有诱导T细胞无反应性的能力。

And determined the proliferation of anergic T cells response to exogenous IL-2 and different doses of SEA.

并测定无能T细胞对加大SEA剂量和外源性IL-2的应答反应。

流式细胞仪检测无能细胞的表型。

The responsiveness of anergic T cells could be restored gradually after some times.

但体内外诱导的无能T细胞经过一段时间的休息，其应答反应是可以逐渐恢复的。

Objective: Study the correlation between T cell anergy and apoptosis.

目的：探讨无能T细胞与凋亡的关系。

Study on the induction, property and mechanism of T cell anergy
