Objective To observe the effect of laser photocoagulation of the peripheral retinal holes and/or degeneration in high myopia. Methods Full fundus examination for high myopic patients was made before keratorefractive surgery with binocular indirect ophthalmoscopy.Peripheral holes,degeneration and vitreous traction were found in 206 eyes of 135 patients,and all of them were treated with laser photocoagulation. Results No retinal detachment occurred after keratorefrative operation within 1 year follows up. Conclusions Retinal laser photocoagulation is an effective and safety method before keratorefractive operation for prevention of the retinal detachment in high myopia at least in short-term observation.

目的:觀察外傷性腎損傷出血行腎動脈栓塞術及護理效果。方法:本組26例，其中12例有失血性休克。均采用Seldinger技術，經股動脈穿刺選擇性腎動脈造影，超選擇性插管后注入栓塞劑。術前重點監測生命體征，及時補液、止血、輸血防治休克。術中順應醫師的操作，觀察生命體征、小便量、色的變化。術后:重點預防穿刺點出血，觀察下肢血液循環，處理疼痛，發熱等并發癥。結果:26例患者臨床癥狀很快緩解，血壓均在12h內恢復正常，血尿在1～2天消失，有效率達100%。結論:外傷性腎損傷出血，采用腎動脈栓塞術即可立刻止血，又可為患者保全功能正常的腎臟。
Objective To evaluate the correlation between retinal thickness (RT) at the macular area and the axial length (AL) in myopia. Mehtods Optical coherence tomography (OCT) was used to detect the RT at the macular fovea, and at the superior, nasal, inferior, and temporal side of the fovea and parafovea area. The AL of the examined eye was measured by IOL master measuring machine, and the correlation between RT at the macular area and the Al was evaluated. Results The minimum RT in the macular area in the eyes with myopia was (150.90plusmn;22.10)mu;m.The retina at the temporal side of parafovea was the thinnest. The average RT in the areas around the fovea was negatively correlated with the AL, and there was no correlation among the minimum RT, the mean RT at the fovea, and the AL of eye. Conclusions As the AL of eye increases, the RT at the parafovea decreases, while the minimum and the average RT at the fovea remain unchanged. (Chin J Ocul Fundus Dis, 2006, 22: 397-399)
Objective To observe and analyze the configuration and distribution of vortex veins by indocyanine green angiography (ICGA) combining with widefield contact lens system. Methods A total of 28 patients (32 eyes), including 16 females (19 eyes) and 12 males (13 eyes) with the age of 28-84 (average 71), were examined by ICGA combing with widefield contact lens. The patients were divided into high myopia group (15 eyes with diopter ge;-6.0 D) and non high myopia group (17 eyes with diopter lt;-6.0 D or normal sight). Results A total of 166 vortex veins were detected, including 118 circinate veins (71.1%), 34 thick-stripe-like veins (20.5%), and 14 irregular vein (8.4%). There are 71 vortex veins in the right eyes with average 5.07 vortex veins in each eye; and 95 veins in the left eyes with average 5.28 vortex veins in each eye. The number of vortex veins at in the inferior temporal, inferior-nasal, over-temporal and over-nasal retina was 47, 42, 39, and 38, respectively, with average 1.34 vortex veins in each quadrant (the inferiortemporal was the most: average 1.53). A total of 160 vortex veins came out from the scleral around the equator area 46 disc diameter (DD) away from the optic disc (964%); the other 6 vortex veins came out at the point 3-4 DD away from the optic disc (3.6%). A total of 123 (74.1%) vortex veins had ampullae with different directions. Horizontal and vertical ampullae were most common. There was no difference in numbers and configuration of vortex veins beween the two groups. Conclusion The vortex veins has circinate, thick-stripe-like, and irregular configurations; the distribution of vortex veins in eyes with high myopia or non high myopia is almost accordant. ICGA combining with the wide-field contact lens examination can observe all of the vortex veins within a single visual field.
ObjectivesTo systematically review the efficacy of dyclonine and lidocaine for preparation before gastroscopy.MethodsPubMed, CNKI, CBM, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) of dyclonine vs. lidocaine for preparation before gastroscopy from inception to December 31st, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 11 RCTs were included. The results of meta-analysis showed that: dyclonine could improve anesthetic effect (RR=1.38, 95%CI 1.31 to 1.47, P<0.000 01), and was more capable to remove bubble (RR=1.40, 95%CI 1.28 to 1.52,P<0.000 01), and had superior textures (RR=1.43, 95%CI 1.18 to 1.74,P=0.000 3).ConclusionsOral dyclonine can improve the visual definition of gastric mucosa and anesthetic effect, and has superior textures. Thus, dyclonine can be regarded as a recommended option prior to gastroscopy. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
