The neonatal neurological and adaptive capacity scores ( NACS) of breast-feeding newborns were measured at 24,48,72,% h after cesarean section in two groups. Visual analogue scales ( VAS) of the parturients were recorded during PCEA.

测定两组母乳喂养的新生儿术后24、48、72、96h的神经适应能力评分（NACS）及观察组产妇术后镇痛的VAS评分。

When it came to the substitution degree of NaCS, it increased with increase of reaction time gradually, and kept about 0.5 from 6 h. In addition, the degradation of NaCS by cellulose decreased with the increase of the preparation time of NaCS.

NaCS的取代度随着反应时间先逐渐增大，到6h后，取代度保持在0.5左右。通过纤维素酶降解实验可知，NaCS的降解性随着其制备时间的增加而呈现逐渐下降的趋势。
