Objective To evaluate the nutritional status of vitamin A among urban residents. Methods Using stratified random sampling method,a total of 400 residents from two cities in Zhejiang were selected. They were interviewed by questionnaire,also, the dietary survey, physical measurement and blood sample testing were used. According to Recommended Nutrient Intake( RNI)of vitamin A,to evaluate the intake of Vitamin A and analysis the nutritional status and influenc factors. Results The median of vitamin A concentration was 0. 463( inter-quartile range is 0. 213)μg/mL, and the percentage of severe vitamin A deficiency( VAD ),VAD,insufficiency and adequate serum vitamin A were 0. 25%,0. 50%,6. 75% and 92. 50% respectively. Among 299 individuals who participated in the dietary survey,the median of daily vitamin A intake was 350. 5( inter-quartile range was 351. 5)μgRE. Only 25. 42% of participants' dietary intake of vitamin A met the level of 80% RNI,while 61. 87% of peoples' daily intake of vitamin A under 60%RNI. Male, from the bigger city,older age,high level of triglyceride and more intake of cholesterol may contribute to a higher level of serum vitamin A. Conclusion The majority of urban residents had adequate vitamin A . But the intake of dietary vitamin A still should be paid more attention. Serum vitamin A was associated with age,gender and district.

OBJECTIVETo study the effect of progesterone on matrix metalloproteinase-3 (MMP-3) expression in neonatal rat brain after hypoxic-ischemia.

METHODSFollowed the hypoxic-ischemia of neonatal rat brain, Evans blue (EB) staining and transmission electron microscopy were used to detect the blood-brain barrier pathological changes on permeability. MMP-3 protein expression in cerebral cortex was measured with Western blot.

RESULTSTransmission electron microscopy results showed that the blood brain barrier in hypoxic-ischemic group changed significantly compare to progesterone group. EB staining results suggested that the blood-brain barrier permeability of hypoxic-ischemic group was significantly increased compared to sham-operated group (P < 0.01). The blood-brain barrier permeability in progesterone group was also decreased in comparison to that of hypoxic-ischemic group (P < 0.05). Western blot image analysis results indicated that MMP-3 protein expression in the hypoxic-ischemic group increased significantly than that in sham-operated group (P < 0.01), and the progesterone group was decreased significantly than that in hypoxic-ischemic group (P < 0.05).

CONCLUSIONProgesterone may reduce the blood-brain barrier damage by reducing MMP-3 expression. This might be one of the protective mechanisms in the hypoxic-ischemic brain injury.
