[Methed] The quality analysis was conducted on on-season and off-season Iongan, which are main cultivars in Hainan consistent in maturity. In order to understand the quality characteristics of Hainan fresh Iongan, saccharide contents, vitamin C content, edible rate, TSS, weight of single fruit, weight per fruit cluster and pesticide residues were detected in this study. [Result] There were no significant differences in quality between on-season and off-season Iongan, and the content of TSS in off-season fruit was slightly higher than that in on-season Iongan. The two main cultivars ‘Shixia＇ and ＇Chuliang＇ in Hainan differed significantly in edible quality. The weight of single fruit and edible rate of ‘Chuliang＇ were slightly higher than those of ‘Shixia＇ Iongan, and their sucrose contents were nearly equivalent. Vitamin C and TSS contents in ‘Shixia＇ Ionganwere higher than those in ‘Chuliang＇.‘Shixia＇ had a monosaccharide content significantly higher than ‘Chuliang＇, while its sucrose content was lower than ‘Chuliang＇. Only low contents of residual cypermethrin and diflubenzuron were detected in pericarp, and the contents of the 9 pesticides in fruit flesh were all lower than their detection limits. [Conclusion] Longan fruit produced in Hainan could all be eaten safely.展开更多

Methods The clinical data of 10 patients diagnosed with UES in our hospital between 1990-2010 were extracted from hospital records and analyzed, including ophthalmologic examination, ophthalmologic ultrasonography, ultrasound biomicroscopy (UBM), fundus fluorescence angiography (FFA), indocyanine green (ICG) angiography, surgical procedures, and outcomes. Results The fundus examination of all impacted eyes showed bullous retinal detachment shifting with head position, confirmed by ultrasonography revealing retinal and choroidal detachment. UBM showed annular peripheral ciliochoroidal detachment in all cases. FFA was performed in 5 patients and revealed leopard spots without leakage from choroid into subretinal space. ICG angiograpy was performed in 3 patients and demonstrated diffused granular marked hyperfluorescence in the choroidal fluorescence in the very early phase, which increased with time and persisted until the late phase. Four eyes of 2 patients underwent full-thickness sclerectomies and 1 eye of 1 patient underwent subscleral sclerectomy, all of whom achieved reattachment of the retina without recurrence during 1-year follow-up. Conclusions Comprehensive preoperative evaluation, including ophthalmologic ultrasonography, computed tomography, and magnetic resonance imaging, is crucial for accurate classification of UES and selection of proper management strategy. Surgical treatment can achieve optimal clinical outcomes for type 1 and type 2 UES.展开更多
