Objective To investigate the changes of protein and energy intakes and the z-score of weight for age in appropriate for gestational age (AGA) and small for gestational age (SGA) preterm infants with gestational age less than 34 weeks. Methods The data from 314 hospitalized premature infants ( 268 cases of AGA and 46 cases of SGA) during January 2012 to December 2014 were retrospectively collected. The intakes of protein and energy and the changes of weight within 2 weeks after birth were compared. Results Compared with AGA group, the hospital stays, durations of parenteral and enteral nutrition and total enteral nutrition, and time to achieve full dose feeding were signiifcantly longer in SGA group (P?0 . 05 ). The energy intakes on day 4 , 8 , and 12 after birth in SGA group was obviously lower than in AGA group;the protein intakes on day 6 and 8 in SGA group was also obviously lower than in AGA group (P?0 . 05 ). The daily average weight gain was signiifcantly higher in SGA group than that in AGA group (P?0 . 05 ). The z-score of weight for age was gradually away from the median level in both AGA group and SGA group within 2 weeks after birth. Moreover, the z-score of weight for age at 2 weeks was lower in SGA group than that in AGA group (P?0 . 05 ). Conclusions The growth velocity in SGA premature infants was faster than that in AGA premature infants with gestation age lower than 34 weeks after recovery of birth weight. There was catch-up growth to some extent. However, the growth of SGA and AGA premature infants need to be improved.

Objective:
To compare the disinfection effect of three-hole polypropylene infusion bottle stopper by central sterilization method and groove central sterilization method, and to explore the best method of three-hole polypropylene infusion bottle cap disinfection.
Methods:
A total of 1 088 bottles of three-pore polypropylene infusion bottles from 10 hospitals in Panzhihua City and the surrounding areas of Chengdu were selected for disinfection, and the effects were compared by fluorescent powder tracing method and bacterial culture method respectively. The two methods were divided into two groups: bottle stopper Central Sterilization group and groove Central Sterilization group. Each nurse sterilized two groups of liquid.
Results:
The total area of fluorescent powder residues after disinfection of 272 bottles of infusion bottles with different specifications
