2GABA免疫反应的变化：OVX+NS+NS、OVX+NS+PTZ和OVX+P+PTZ三组间齿状回门区内GABA免疫阳性细胞数存在显著差别(P＜0.01)。

Fluorescein isothiocyanate labeled polyclonal goat antihuman immunoglobulin antibody was added, and flow cytometer was used to detect bead-platelet-associated autoantibodies-antihuman immunoglobulin antibody complex. Results The fluorescene ratio of four monoclonal antibodies was significantly different (P .01) between the idiopathic thrombocytopenic purpura patients and either the non-ITP patients or the normal controls. If the upper limit of normal control was set as cutoff value, ratios of greater than 1.37, 1.24, 1.48, and 1.19 were considered positive for the four monoclonal antibodies respectively. The flow cytometric bead assay had an overall sensitivity of 73.17% and a specificity of 94.29%.

结果 特发性血小板减少性紫癜组4种单抗荧光强度比值与非ITP血小板减少组和正常对照组有显著性差异（P＜0.01）；若将ITP组患者4种单抗荧光强度比值分别大于正常对照组上限1.37、1.24、1.48和1.19判断为阳性，则流式微球技术检测血小板特异性自身抗体的敏感性为73.17%，特异性为94.3%；4种单抗联合检测总体敏感性明显高于改良间接单抗特异的血小板抗原固定试验（P＜0.05，且大于各单个抗体检测敏感性。

It is proved that if'sparse NP complete sets under polynomial-time Turing reductions exist'then 'SAT is polynomial-time non-adaptively search reducible to decision', and that if 'P is not equal to NP'then either'SAT is not polynomial-time non-adaptively search reducible to decision'or'SAT is not polynomial-time truth-table reducible to bounded approximable sets', and that if'P is not equal to NP'then'sparse complete sets for NP under polynomial-time disjunctive reductions do not exist'.

因为用现有的证明技术不可能绝对地解决这个假设，本文研究了这个假设与其他关于SAT结构性质的假设之间的关系，证明了如果'NP有多项式时间图灵归约下的稀疏完全集'则'SAT是多项式时间并行地搜索归约为判定'，以及如果假设'P不等于NP'，则要么'SAT不是多项式时间并行地搜索归约为判定'，要么'SAT不能用多项式时间真值表归约归约为有界可近似集'。
