Hypoxia increased the percentage of intra-acinar muscular and decreased the one of nonmuscular artery. 764-3 could reduce MA% from 33.75±11.26 (H2w) to 21.25±5.86 (7-H2w, p＜0.05) and from 41.50±10.70 (H4w) to 26.67±10.92 (7-H4w, P＜0.05), respectively; meanwhile, increase NMA% from 35.42±9.00 (H2w) to 45.42±2.92 (7-H2w, p＜0.05) and from 21.50±9.29 (H4w) to 33.33±5.40 (7-H4w), p＜0.05, respectively.

与正常组大鼠相比，缺氧2周、4周后MA％明显增加，分别为33.75±11.26(＜0.001)和41.50±10.70(p＜0.01)；NMA％显著减少，分别为35.42±9.00(p＜0.001)和21.50±9.29(p＜0.001)。764-3处理的大鼠其三型血管比例的失调得到部分改善。7-H2w组与7-H4w组MA％分别为21.25±5.86和26.67±10.92(p均＜0.05)，NMA％为45.42±2.92和33.33±5.40(p均＜0.05)。

Pulmonary microvascular endothelial cells, one of pivotal effective cells against pathopoiesis factor in early stage of disease, are proved to play an important role in mediating inflammatory response, aggravating tissue hypoxia, and secreting cytokines and matrix to regulate the migration, proliferation and differentiation of mesenchymal cells.

然而，它在消除致病因子对机体损伤的同时也可能由于某种原因而过度地发挥了介导免疫、炎症反应，加重组织缺氧，分泌过量细胞因子等生物学作用，从而促进了组织的纤维性修复。

Serum containing SSTG was obtained at different time after perorally administrated with different dose of SSTG.The cardiomyocytes were deprived of oxygen and glucose to mimic hypoxia reoxygenation injury and were treated by serum containing SSTG when reoxygenation.LDH content in supernatant was detected after reoxygenation.LDH release suppression rate was used to study the time-effect and dose-effect of serum containing SSTG.
