目的:观察外伤性肾损伤出血行肾动脉栓塞术及护理效果。方法:本组26例，其中12例有失血性休克。均采用Seldinger技术，经股动脉穿刺选择性肾动脉造影，超选择性插管后注入栓塞剂。术前重点监测生命体征，及时补液、止血、输血防治休克。术中顺应医师的操作，观察生命体征、小便量、色的变化。术后:重点预防穿刺点出血，观察下肢血液循环，处理疼痛，发热等并发症。结果:26例患者临床症状很快缓解，血压均在12h内恢复正常，血尿在1～2天消失，有效率达100%。结论:外伤性肾损伤出血，采用肾动脉栓塞术即可立刻止血，又可为患者保全功能正常的肾脏。
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.

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.
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)
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.
