Objective To assess the nutritional status of vitamin A among adults of ethnic minority groups native to Yunnan Province, and provide scientific evidence for healthy eating promotions. Methods Between 2016 and 2020, 841 adults were randomly sampled from seven ethnic minority groups according to the sex and age composition in the 6thnational census. The serum retinol level was determined using high-performance liquid chromatography (HLCP), and judged by the WHO criteria. Vitamin A intake was calculated through a dietary survey and judged by reference to the dietary guidelines. Results The median serum vitamin A concentration was 0.55 mg/L (ranging from 0.44 to 0.68 mg/L) and significant differences were found in sex, race, education and income levels (all P < 0.05). The prevalence of vitamin A deficiency and marginal deficiencies were 0.7% and 3.7%, respectively. The median of dietary vitamin A intake was 406.0 µg retinol equivalents (RE) and 67.0% of the subjects consumed less vitamin A than the Chinese Estimated Average Requirement (EAR). The major food sources of vitamin A were dark vegetables, eggs, light vegetables and meat, accounting for 86.6% of total vitamin A intake. Conclusion The serum vitamin A concentration is relatively good in the population, whereas inadequate vitamin A intake remains a problem, especially for certain ethnic groups, older and poor adults.

Objective To obtain the pass rate of driving test of monocular visually impaired patients in Yunnan province and analyze the cause of monocular visually impaired patients．Methods We performed Visual acuity， computer Optometry， horizontal visual field， color vision and slit-lamp microscope on each of the physical participants. In this survey， 294 people who had undergone medical examinations from January 2018 to April 2018 were divided into three groups for retrospective analysis by age. The uncorrected distance visual acuity of the superior eye or corrected distance visual acuity reaches the logarithmic vision table 5.0 and above， the horizontal field of vision reaches 150 °， and there is no red-green blind person who passes the medical examination. The statistical method uses SPSS19 .0 statistical software， mainly descriptive statistics．Results 250 males and 44 females were included in the analysis. The ratio of males to females was 5:1. Age 18-60 years old， average age 32 ± 8 years old. The overall pass rate for medical examinations was 69.4 %，68.8%for men and 72.7%for women. The lowest pass rate for men and women is over 40 years old （χ2 =12.676，P＜0.001 and χ2 =11.092，P=0.001） ; The pass rate of men gradually decreases with age. Among the causes of monocular vision disorders， 148 male eye injuries， 68 amblyopia， and 34 others; Female eye trauma 7， amblyopia 29， other 8. Most of the injuries occurred in young age， including 96 sharp injuries， 48 bullet injuries， and 11 explosive injuries．Conclusion At present， the pass rate of the one-eye vision impairment driver's license in our province is 69.4 %. Among the causes of monocular vision disorders， the most important male eye trauma in early childhood， followed by the failure to detect and treat amblyopia in time; The most important female amblyopia is not found and treated in time.

Objective To analyze the fundus characteristics and fluorescein angiography of morning glory syndrome．Methods The morning glory syndrome patients' fundus photography and fundus fluorescein angiography were analyzed in our hospital．Results Fundus examination showed: a large disc with a funnel-shaped excavation surrounded by an annulus of choriorretinal atrophy. A white tuft of glial tissue overlies the central portion of disc. The blood vessels emerged from the rim of excavation in a radial pattern，and they increased in number and it was difficult to distinguish arteries fromveins. Angiographic characteristics: in the central of disc the white tissue was blockage of fluorescence or hypofluorescence which was surrounded by is hyperfluorescence， and at the outside is transmitted fluorescence. It's rarely to see fluorescein leakage．Conclusion The fundus examination， fundus fluorescein angiography and combination of patients' history are helpful to confirm the diagnosis of morning glory syndrom.
