目的 探讨视网膜下猪囊尾蚴患者的眼底荧光血管造影特征.方法 对由眼底彩色照相、眼部B超证实的视网膜下猪囊尾蚴患者进行眼底荧光血管造影检查,分析其结果,并与相关疾病进行鉴别诊断.结果 眼底荧光血管造影动脉期可见病灶表面视网膜血管开始充盈,病灶并未遮蔽或轻微遮蔽脉络膜的背景荧光.静脉期病灶表面视网膜血管继续充盈,毛细血管网清晰可见,勾勒出与眼底病灶轮廓一致的隆起病灶.晚期虫体组织表面呈弥漫性强荧光,表面视网膜血管呈逐渐模糊的线状强荧光.3例患者晚期可见视网膜毛细血管轻微扩张渗漏,管壁荧光素着染.2例患者可见视盘边界欠清晰、视盘表面毛细血管渗漏呈弥漫性强荧光.结论 眼底荧光血管造影可帮助判断视网膜与虫体的解剖位置关系,了解猪囊尾蚴虫体对视网膜组织、血管、视神经的病理性损伤作用,并与相关占位、炎症性疾病进行鉴别诊断.

Objective To explore the characteristics of fundus fluorescein angiography (FFA) in patients of subretinal cysticercosis.Methods Patients diagnosed as subretinal cysticercosis confirmed by fundus photography and B scan,FFA were carried out and analyzed.Results During the arterial phase,the retinal vascular began filling and the lesion did not obscure or slightly obscure choroidal background fluorescence.During the venous phase,retinal vessels continue filling,capillary network clearly visible,and outline fundus lesions profile consistent with the subtinal cysticercosis.During the late phase,the surface of parasite tissue showed a strong fluorescence,retinal vessels gradually showed fuzzy linear strong fluorescence.Three patients with visible retinal capillary slight expanded and fluorescein leakage,Optic disk boundary were not clear and optic disk surface capillary leakage in 2 patients.Conclusions FFA can help us to judge the retina and cysticercosis in the anatomical position,underst

目的：分析总结描述后巩膜炎的眼科影像学特征。 方法：在我院2008-10/2013-06期间确诊的后巩膜炎患者16例21眼的临床资料进行回顾性分析,分析B超、眼底彩色照相、眼底荧光血管造影、CT结果,对后巩膜炎眼科影像学特征进行综合评价与分析。 结果：所有患者均行B超检查,B超表现分为弥漫型和结节型两种,弥漫型表现为巩膜弥漫增厚,其后有筋膜囊水肿性低回声暗区与视神经相连,形成典型的“T”形征；结节型表现为巩膜结节型回声增强,内部结构较规则。 FFA表现为动脉早期见斑驳状相对弱荧光,动静脉期出现多发针尖样强荧光,逐渐变大融合；晚期荧光素渗漏至视网膜下组织；视盘有不同程度的强荧光,边界欠清或不清。 CT结果表现为眼球球壁增厚。 结论：后巩膜炎好发于中青年女性患者,其眼科影像学的表现多变,以B超表现较有特异性；选择合理的眼科影像学检查手段,并结合临床表现,能够准确诊断后巩膜炎,避免漏诊和误诊现象的发生。

AlM: To analyze, summarize and describe ophthalmic imaging features of posterior scleritis. METHODS: Clinical data of 16 patients ( 21 eyes ) with posterior scleritis diagnosed in our hospital from October 2008 to June 2013 were retrospectively analyzed. The results of type-B ultrasonic, fundus chromophotograph, fundus fluorescein angiography, CT were recorded for comprehensive evaluation and analysis of ophthalmic imaging features of posterior scleritis. RESULTS: All patients underwent type-B ultrasonic examination and manifested as diffuse and nodular types. The diffuse type showed diffusely thickened sclera and a dark hypoechoic area that connected with the optic nerve to form a typical “T”-shaped sign. The nodular type showed scleral echogenic nodules and relatively regular internal structure. FFA showed that relatively weak mottled fluorescences were visible in the arterial early phase and strong multiple needle-like fluorescences were visible in the arteriovenous phas

目的探讨阴茎海绵体造影（CG）对静脉性勃起功能障碍（ED）的诊断价值。方法由临床筛选的静脉性ED患者80例,对其进行阴茎海绵体造影,对比观察造影结果。结果静脉漏性ED的X线表现分为：背深静脉漏23例、脚静脉漏13例、背浅静脉漏7例、间静脉漏3例、海绵体静脉漏5例、混合静脉漏30例。结论 CG是诊断静脉性ED的可靠方法,可准确显示静脉漏的部位,指导临床治疗。

Objective To assess the clinical value of cavernosography in intracaver nous injection test (ICI) induced erection in the diagnosis of ED. Methods 80 cases with venous ED diag-nosed by clinical screening tests were subsequently performed cavernosography.Angiographic results were comara tively stydued.Results According to the X-ray find ings, venous ED was classified into 6 types,profundus venous leakage,23cases;Toot venous leakage,13 cases;Superficial venous leakage,7 cases;Middle venous leakage,3 cases;Cavernous leakage, 5 cases;The mixed leakage,30 cases. Conclusion Cavernosography is a simple and effective screening test for the detec tion of venous ED, and identifying the abnormal leakage. It is helpful for clinical therapy.

目的 探讨下肢静脉在重症新生儿PICC中的应用优势.方法 将2012年1～12月在新生儿科住院的165例重症新生儿随机分配为PICC上肢静脉组(首选贵要静脉,其次是肘正中静脉、头静脉)73例和PICC下肢静脉组(首选大隐静脉,其次是腘静脉)92例,通过对比置管一次成功率及置管后的并发症如尖端异位、导管堵塞、静脉炎等明确上下肢静脉置管的优劣性.结果 下肢静脉组的置管一次成功数量明显大于上肢静脉组,且下肢静脉组导管尖端易异位也比上肢静脉组少.而在并发症方面:静脉炎、导管堵塞、导管断裂、敷贴过敏等隋况2组比较差异无统计学意义.结论 下肢静脉PICC穿刺较传统的上肢静脉PICC穿刺更有临床应用优势.

Objective To investigate the advantage of detaining peripherally inserted central catheter through the veins of lower extremity in neonatal intensive care unit.Methods 165 cases of infants were randomized into veins of lower extremity group (first saphenous veins,then popliteal vein) and veins of upper extremity group (first basilic vein,then median cubital vein,cephalic veins) from January to December 2012.We observed the success rate of detaining,catheter tip location,and complications such as phlebitis in the two groups.Results The success rate of detaining of lower extremity group was higher than that of upper extremity group,and ectopic rate of lower extremity group was lower than that of upper extremity group.There was no significant difference in complications such as phlebitis between two groups.Conclusions Peripherally inserted central catheter through the veins of lower extremity has more advantage over through the veins of upper extremity group.
