OBJECTIVE:To explore the effects of enteral nutrition powder in children with phenylketonuria(PKU)under one year. METHODS:120 PKU children under one year were selected and given enteral nutrition powder(20 g/kg,qd)for consecutive 32 weeks. The level of benzene,height,weight,head circumference,IQ level,nutrition indicators and ADR were compared be-fore treatment,8 weeks after treatment,32 weeks after treatment. RESULTS:8 and 32 weeks after treatment,the level of benzene decreased gradually,and height,weight and head circumference increased gradually,with statistical significance(P<0.05). IQ lev-el of children after 8 weeks treatment were better than before,and those of children after 32 weeks treatment were better than after 8 weeks treatment,with statistical significance(P<0.05). 8 and 32 weeks after treatment,nutrition indicators were improved sig-nificantly,compared with before treatment;ALT,Alb and TP levels 32 weeks after treatment were significantly better than 8 weeks after treatment,with statistical significance(P<0.05).There was no statistically significant difference in BUN,TBil and Pa levels between 32 weeks after treatment and 8 weeks after treatment(P>0.05). 66 cases suffered from 181 times of ADR,mainly including 10 times diarrhea and 126 times upper respiratory tract infection,among which one children developed moderate gastroen-teritis. They were all recovered after symptomatic treatment. CONCLUSIONS:For PKU children under one year,enteral nutrition powder can effectively control the phenylalanine levels,prevent the decrease of IQ and improve the nutritional status so as to meet the normal growth and development of children nutritional requirements,with better safety and tolerance.

Objective To explore a novel and highly specific small-molecule TNFβinhibitor by using computer-aid?ed virtual screening and cell-based assays in vitro. Methods Computer-aided drug design and virtual screening were used to design and identify chemical compounds that targeted TNFβbased on the crystal structure of the TNFβ-TNFR1 com?plex. The effect of the small-molecule compound against TNFβ-induced cytotoxicity of L929 cells was detected by MTT as?say, and the efficacy of the compound to inhibit TNFβ-induced apoptosis of L929 cells was determined by flow cytometry as?say. The impact of the compound on L929 cell cycle was examined by Propidium Iodide (PI) staining and flow cytometry, and the influence of the compound on TNFβ-triggered signal pathway was analyzed by Western blot assay and Ultra VIEW VOX 3D Live Cell Imaging System. Results No.35 compound (named as C35 thereafter) could effectively inhibit TNFβ-induced cell death in a dose dependent manner, and the half-maximum inhibition concentration (IC50) was 8.19μmol/L. Furthermore, C35 had lower cytotoxicity and minimal effect on L929 proliferation. Here we further revealed that C35 could affect TNFβ-induced apoptotic pathway by blocking the activation of Caspase 3, and markedly reduce L929 cell apoptosis induced by TNFβ. Conclusion A novel TNFβsmall-molecule inhibitor was identified by combining computer-aided virtual screening with functional assays, and which could block TNFβ-triggered apoptotic pathway and efficiently inhibit the cell death in?duced by TNFβ.
