Abstract:
Objective To observe the changes of serum IGF-I,VEGF levels in premature infants,and to dis-cuss the predicting values for the development of ROP;Methods Preterm infants admitted into those whose birth weight ( BW)≤1 500g and ( or) gestational age ( GA)≤31 weeks joined in ROP-screen,and those who were diag-nosed as ROP according to ICROP were included into ROP group.In the same time,those who didn't develop ROP were divided into the control group.Serum IGF-I,VEGF were measured one week from their birth or correct gestational age of 31 weeks.Serum IGF-I, VEGF were evaluated with ELISA method.Results The concentration of IGF-I, VEGF:Group ROP[(20.65 ±11.11)μg/L,(195.61 ±105.98)ng/L] were all significantly lower than the control group [(42.86 ±18.72)μg/L,(363.59 ±101.08)ng/L](all P<0.01).There were significant different of birth weight[ROP group (1 229.69 ±232.37)g,the control group (1 401.32 ±171.78)g;t=4.144)],GM[ROP group (3.20 ±1.23)mmol/L,the control group (3.70 ±1.17)mmol/L;t=2.082],the time of oxygen inhaling[ROP group (32 ±22)d,the control group (21 ±12)d;t=-2.856],oxygen inhalation mode(the percentage of mechanical ventilation)[ROP group 33/48(68.8%),the control group 16/50(32.0%);χ2 =16.363] and fertilization way(the percentage of test tube baby)[ROP group 13/48(27.1%),the control group 4/50(8.0%);χ2 =6.262] between ROP and control group (all P<0.05).Conclusion The low serum IGF-I(<28.08μg/L),VEGF(<232.89ng/L) of a premature in the first week or correct gestational age of 31 weeks and (or)BW≤1 500g would probably suggest the development of ROP.
