Our study shows that Bax ,the protein of accelerating apoptosis, may participate in the proliferation and regression of hemangioma. 2 The expression of TGFβ1 in the involuting phase was higher than in the proliferative phase, the difference was statistically significant, p＜0.01. 3 This shows that Bax and TGFβ1 may be the important factors which cause the apoptosis of hemangioma and accelerate its regression as well.

1 Bax在血管瘤增生晚期开始表达，至退化期Bax的表达达到高峰，提示Bax这种促进细胞凋亡的蛋白参与血管瘤的增生与退化过程。2 TGFβ1在血管瘤退化期的表达高于增生期，差异有统计学意义，p＜0.01.3 提示Bax与TGFβ1可能是引起血管瘤凋亡，进而促进其退化的重要因素。

In practical work, we can fit the empirical equation of regression according to least square method when we use the old data, and needs to make the Real-time treatment for new acquired data in the light of the equation, namely, we need combine new acquired data with the original data, then infer the new empirical equation of regression.
