The invention belongs to the field of food, and particularly relates to a nutritional composition for improving intestinal microecology and application thereof. The nutritional composition provided by the invention comprises necessary active ingredients as shown in the following (I) and (II): (I) lactose-N-neotetraose, (II) 1, 2-diacyl-sn-glycerol-3-phosphorylcholine, and (f) 1, 2-diacyl-sn-glycerol-3-phosphorylcholine, the nutritional composition comprises lactose-N-neotetraose and 1, 2-diacyl-sn-glycerol-3-phosphorylcholine, and in the nutritional composition, the mass ratio of the lactose-N-neotetraose to the 1, 2-diacyl-sn-glycerol-3-phosphorylcholine is 1: (0.010-3.0). Researches show that lactose-N-neotetraose and 1, 2-diacyl-sn-glycerol-3-phosphorylcholine can improve offspring intestinal microecological imbalance caused by maternal immune activation in a synergistic manner, and benefit is provided for offspring nervous system development.

A method for treating or reducing the severity of neurodevelopmental defects in a developing nervous system after exposure to an anesthetic by modulating or inhibiting caspase activity, for example, by administering a pan-caspase inhibitor such as pan-caspase inhibitor Q-VD-OPh to a subject having or at risk of congestive heart disease and / or having a ciliopathic disorder.

The present application belongs to the field of food, and particularly relates to a nutritional composition for improving intestinal microecology and use thereof. The nutritional composition provided by the present application comprises essential active ingredients shown in (I) and (II) as follows: (I) lacto-N-neotetraose, (II) 1,2-diacyl-sn-glycero-3-phosphocholine; and in the nutritional composition, the mass ratio of the lacto-N-neotetraose to the 1,2-diacyl-sn-glycero-3-phosphocholine is 1:(0.010-3.0). Studies show that both lacto-N-neotetraose and 1,2-diacyl-sn-glycero-3-phosphocholine can synergistically improve the intestinal microecological imbalance of offspring caused by maternal immune activation and provide benefits for the nervous system development of offspring.
