International Eye Science 2016;16(6):1147-1149
?AIM:To investigate and analyze the prevalence and the influencing factors on retinal arteriosclerosis in civil aviators of different ages.?METHODS:Two thousand seven hundred and seventy-eight commissioned civil aviators who received medical examination in Civil Aviation General Hospital from July 2014 to July 2015 were randomly divided into three groups: group A ( 1 311 aviators aged 22-39 ) , group B (618 aviators age 40-49 ), group C(849 aviators age 50-59). Aviators over 40 years old, were divided into two groups: group with retinal atherosclerosis and group without retinal atherosclerosis according to the results of fundus examination. Medical examination data of the aviators were analyzed.?RESULTS: Of 2 778 aviators, 334 ( 12. 02%) were detected with retinal arteriosclerosis, among which 318 aviators were classified as gradeⅠ, and 16 aviators as grade Ⅱ. The retinal arteriosclerosis prevalence of group A, B, and C increased with age, and the difference was statistically significant ( P < 0. 05 ). Biochemical tests showed that the prevalence of hypertension, hyperlipidemia, high fasting blood glucose and overweight increased in group with retinal arteriosclerosis compared with that in group without retinal arteriosclerosis, and the difference was statistically significant(P<0. 05).?CONCLUSION:The prevalence of retinal arteriosclerosis in commissioned civil aviators was 12. 02%, and most of the retinal arteriosclerosis was classified as grade Ⅰ. In aviators over 40 years old, hypertension, hyperlipidemia, high fasting blood glucose and overweight were important factors in the development of retinal arteriosclerosis.

Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

Objective To study the anatomical characteristics of the stellate ganglion (SG) for providing morphological data for SG block. Methods The shape, size, position, and relation of 30 cases of SG in 15 adult cadavers were observed and measured. Results Most of the SG was stellate-shaped. The average volume of the stellate ganglion was (0.86?0.07)cm3. The position of the SG could be localized according to the adjacent bone or muscle marks, and the shortest distance was between the SG and the transverse process of the 7th cervical vertebrae. There were many important structures around the SG, in which the vertebral artery was closely related to the SG. Conclusion During performance of the SG block, the surface projection, puncture point, and medication dosage could be judged on the basis of these quantitative anatomic data.
