选择临床心内直视手术病人58例，随机分为对照组和SFI组，SFI组于CPB前予SFI 1ml/kg静注，记录气管插管后10、30、60 min，CPB手术开始时，CPB停止后10、60、120min时的潮气量、气道峰值压、平均气道压并计算肺顺应性和呼吸指数。

He type of ossein in group B was mainly type Ⅰ collagen while that in group A type Ⅱ and it exhibited as a process of fiber formation in group C. The reason for why TGF-β〓 can promote ossification induced by BMP is that can promote the differentiation and proliferation of mesenchymal cells to supply more target cells for BMP, promote the differentiation and proliferation of mature osteocytes and chondrocytes, inhibit metalloproteinase to decrease the destruction of bone tissue and promote calcification of bone matrix.

GF-〓能促进BMP骨诱导作用主要因其能促进间充质细胞的分裂增殖为BMP提供丰富的靶细胞、促进成熟骨及软骨细胞的分裂增殖、促进骨细胞产生Ⅰ型胶原而抑制软骨细胞产生Ⅱ型胶原，抑制金属蛋白酶的活性以减少组织破坏、促进基质钙化等作用而使骨生成能力增加，提示它和BMP具有协同作用。

On the base of applied tech. and system structure, the key tech. are expressed in detail. It includes:Knowledge representation technology: it is described in two stages by "Depictive frame + Rule group"."Depictive frame" is used to reflect the factors concerning question field."Rule group" reflects the son-question in question field; knowledge management system: it is made up of knowledge-base editing component, factor classifying component, knowledge inspecting component and extractive knowledge component; uncertainty reasoning adopt method of elicitation search strategy and data drive controlled by member knowledge. It take reliability of compound proof at first. That can resolve the matching contradiction. Reasoning explanation introduce pre-text and followed method of resolving path. Knowledge discovery component take SLIQ as basic arithmetic. It provides classification model in two stage forms which aim at training suit. That is decision tree and productive rule.
