AIM: To observe the effect of curcumin on the retinal structure and the expressions of interleukin-23 (IL-23) and interleukin-17(IL-17) in the rat retina after retinal ischemia-reperfusion injury (RIRI).METHODS:A total of 60 male Sprague-Dawley(SD) rats were randomly divided into normal control group(NCG),model group(MG),low-dose curcumin group (LDCG) and high-dose curcumin group (HDCG) (n=15 per group).RIRI was generated by anterior chamber perfusion of normal saline to the right eye.Rats in LDCG and HDCG received an intraperitoneal injection of 20mg/kg/d and 100mg/kg/d curcumin respectively,at 30min before RIRI and once daily after RIRI.Retinal structure and inflammation were evaluated after hematoxylin and eosin-stained (HE) staining.Western-blot and enzyme-linked immunosorbent assay (ELISA) were used to measure the level of IL-23 and IL-17 expressions after RIRI.RESULTS: The retinal structure of NCG was normal.Retinal edema,empty spaces or loosely packed cells and inflammatory cell infiltration were observed in MG and LDCG groups,whereas the morphological changes in HDCG group were improved as compared to MG and LDCG groups.Western-blot assay and ELISA showed that IL-23 and IL-17 expressions increased significantly after RIRI (vs NCG,P<0.01).Moreover,curcumin reduced IL-23 and IL-17 expressions significantly (vs MG,P<0.01).CONCLUSION: Curcumin can inhibit leukocytes infiltration and improve the retinal pathologic changes.Furthermore,curcumin can reduce retinal IL-23 and IL-17 expressions significantly in a dose-dependent manner.

?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.

Pseudomonas aeruginosa is one of the most common causes of nosocomial infection due to its intrinsic resistance to antibiotics. In the host,glutathione(GSH) ,one of the most important intracellular antioxidants,provides protection against high levels of oxidative stress. A decrease in GSH levels in tissues infected with P. aeruginosa has been observed while interactions between pyocyanin and GSH maybe partially attribute to P. aeruginosa infection. In this review,the relationship between GSH and the pathogenicity of P. aeruginosa has been discussed based on the author's own research results and the latest literature.
