AlM: To investigate the refractive status of the preschool children in Xiantao, Hubei Province in order to find out the abnormal refraction error beyond the physiological range.
METHODS: ln this cross - sectional study, we investigated preschool children in kindergartens and the scattered ones were 12 716 ( 25 432 eyes ) ranging from 6mo ~ 6 years old. 1 581 children ( 3 162 eyes ) were diagnosed ametropia by Suresight refractive screening instrument, which were confirmed again after mydriasis optometry.
RESULTS: The incidence rate of ametropia in preschool children in Xiantao was 12. 4%, and statistics showed no significant difference between boys and girls (P>0. 05), but had differences of morbility rate among each age group (P<0. 05). With age increasing morbility rate of the refractive error decreased. The simple hyperopia and the compound hyperopia astigmatism were dominant in all refraction error. Professional ophthalmologists diagnosed amblyopia in 261 children (522 eyes), which was 16. 5%, among 1581 abnormal refractive children (3 162 eyes) screened out by Suresight refractive screening instrument.
CONCLUSlON: The incidence rate of ametropia decreases with age increasing in the preschool children from 6mo~6 years old, which imply preschool children should have mydriasis optometry in order to find out amblyopia and other congenital eye disease.

OBJECTIVETo evaluate the therapeutic effect of vascular endothelial growth factor (VEGF) and tumor necrosis factor receptor (TNFR) on avascular necrosis of the femoral head in rabbits.
METHODSAvascular necrosis of the femoral head was induced in 26 New Zealand white rabbits by injections of horse serum and prednisolone. The rabbits were then divided into VEGF/TNFR treatment group, VEGF treatment group, and untreated model group, with another 4 normal rabbits as the normal control group. In the two treatment groups, the therapeutic agents were injected percutaneously into the femoral head. Enzyme-linked immunosorbent assay was performed to determine the concentration of TNF-alpha in rabbit serum followed by pathological examination of the changes in the bone tissues, bone marrow hematopoietic tissue and the blood vessels in the femoral head.
RESULTSCompared with the model group, the rabbits with both VEGF and TNFR treatment showed decreased serum concentration of TNF-alpha with obvious new vessel formation, decreased empty bone lacunae in the femoral head and hematopoietic tissue proliferation in the bone marrow cavity.
CONCLUSIONPercutaneous injection of VEGF and TNFR into the femoral head can significantly enhance bone tissue angiogenesis and ameliorate osteonecrosis in rabbits with experimental femoral head necrosis.
