The purpose of this study is to determine whether iron-fortified TPN is effective in the preventative and treatment of preterm infants. Preterm infants are at risk for anemia especially in preterm infants. Generally the smaller Birth weight and gestational age the higher anemia rate in infants. About 25% to 85% of preterm infants develop evidence of anemia during infancy，77% VLBW（very low birth weight） infants developed anemia during the hospital stay. The effects of iron deficiency are pervasive and involve multiple organ systems. Poor physical growth, gastrointestinal disturbances, thyroid dysfunction, altered immunity and temperature instability has been attributed to iron deficiency in very low birth weight infants. So it is important to provide iron for preterm infants.
As enteral nutrition is not feasible soon after birth in most preterm infants, Parenteral iron administration is an efficacious method for us to select. For most preterm infants the use of TPN(total parenteral nutrition) is very common during the first ten days of life, so we hypothesis that iron-fortified TPN may have a preventative and treatment effect on preterm infants using TPN as a supplementation of oral nutrition; Iron-fortified TPN(total parenteral nutrition) can also improve iron store status of preterm infants. The higher concentration of iron used in this study the larger preventative or treatment effect on preterm infants anemia; It is safe to add Small dose of iron agent to TPN.

Preterm infants are at high risk of anemia especially low birth weight infants, so it is important to supply iron with infants of this group.
90 preterm infants BW(birth weight) less than 2kg,entered neonatal intensive care unit(NICU) less than 72 hours and meet the Inclusion Criteria of this study will be Randomly divided into three groups, control group、 treatment group1 (200μg/kg/d,and the highest concentration of iron is ≤0.8g/100ml TPN)、treatment group2 （400μg/kg/d,and the highest concentration of iron is ≤0.8g/100ml TPN）. iron supplementation period for more than ten days. For three groups, complete blood counts, differential counts, and reticulocyte counts were measured weekly in samples obtained, serum iron, iron protein, total iron binding force were measured at baseline and after 2 weeks. Through comparative analysis of three groups, to find iron-fortified TPN whether affect anemia rate and iron storage in preterm. we also selected malondialdehyde (MDA)and 8-iso-prostaglandin F2α(8-iso-PGF2α) as our concerns about iron used in TPN induces oxidative stress index.
Iron protein determination use radioimmunoassay method, serum iron and total iron binding force determination use chemical method, MDA and 8-iso-PGF2α determination use enzyme-linked immunosorbent assay method.

No Intervention: control group
preterm infants of this group with iron-free TPN for more than ten days, compare serum iron, iron protein, total iron binding force, MDA, 8-iso-PGF2α on baseline and after intervention.
Experimental: treatment group1
preterm infants of this group with iron supplementation of 200μg/kg/d for more than ten days, compare serum iron, iron protein, total iron binding force, MDA, 8-iso-PGF2α on baseline and after intervention.
Other: treatment group1
fe-1 group with TPN of iron supplementation of 200μg/kg/d.
Experimental: treatment group2
preterm infants of this group with iron supplementation of 400μg/kg/d for more than ten days, compare serum iron, iron protein, total iron binding force, MDA, 8-iso-PGF2α on baseline and after intervention.
Other: treatment group2
fe-2 group with TPN of iron supplementation of 400μg/BW (BW=birth weight)
- anemia rate [ Time Frame: up to 2 weaks ]compare the anemia rate of three groups and identify the effect of iron-fortified TPN for preterm infants.
- iron status [ Time Frame: baseline and more than ten days ]Serum iron, iron protein and total iron binding force are parameters used to test the effectiveness of iron-fortified TPN used for preterm infants.
- Oxidative stress parameters Oxidative stress parameters Oxidative stress parameters [ Time Frame: baseline and more than ten days ]we use MDA、 8-iso-prostaglandin F2α as the oxidative stress parameters to identify the safety of iron-fortified TPN used in preterm infants.
