[Relationship between obese gene expressive product and simple obesity in children].
OBJECTIVE
To investigate the relationship between obese gene expressive product-obese protein (OP) and the pathogenesis and prognosis of simple obesity in 30 children with normal body weight (control group).


METHODS
Before immunoassay, OP was extracted from the whole blood samples with Sep-pak C(18) Cartridge.


RESULTS
The plasma contents of OP in the obese group were (118.53 +/- 25.02) ng/L and (197.14 +/- 26.83) ng/L (P < 0.001), respectively. In the obese group, plasma OP was not detected in three cases and was (19.90 +/- 3.94) ng/L in other three cases. These obese children with severe OP deficit not only had more increased body mass index, and levels of total cholesterol, triglyceride and low-density lipoprotein-cholesterol, but also had lower therapeutic effect (16.67%) than those with mild OP depletion (79.16%).


CONCLUSIONS
The children with simple obesity have OP deficit. Simple obesity may be related with the reduced plasma content of OP. The obese children with severe OP deficit have poorer curative effect and unfavorable prognosis.
