Objective To summarize the methods andskills of anterior cervical locking plate systems in clinical application and to analyze the causes of some complications as well as give some preventive or remedial countermeasures. Methods From 1998 to 2002, 159 patients with cervical spondylotic myelopathy,fracturedislocation,tumor or tuberculosis of the cervical spine were treated with anterior locking plate systems. The complications were reviewed and analyzed. Results Ten kinds of complications related to anterior locking plate systems occurred in 21 patients. Most of the complications were caused by improperly-selecting implants, experience and technique deficiency. Conclusio The important preventive or remedial countermeasures are correctly-selecting patients, meticulous preoperative preparation, properly-selecting implants, standard and skillful manipulation and rational postoperative protection.
Objective To observe the factors influencing for results of laser treatment of zone one retinopathy of premature（ROP）. Methods The clinical data of 35 patients（69 eyes）with ROP in zone one who diagnosed by examination of indirect ophthalmoscopy were retrospectively analyzed. The eyes were divided into anterior zone one（49 eyes ）and posterior zone one（20 eyes）. The 69 eyes, aggressive posterior ROP（AP-ROP）in 12 eyes, anterior zone one in four eyes and posterior zone one in eight eyes. The laser photocoagulation of diode indirect ophthalmoscopy with +20 D lens and sclera compressor were used to entire avascular retina. Followup ranged from two to 48 months with the mean of (10.85plusmn;11.35 )months. Take the cristae fadeaway and stable condition as cure; retinopathy proceed to the stage 4 and 5 ROP as retinopathy progress. Results Forty-two out of 69 eyes (60.87%) were cured and retinopathy progress in 27 eyes (39.13%). Thirty-four out of 49 eyes (69.38%) with anterior zone one were cured and retinopathy progress in 15 eyes (30.61%); eight out of 20 eyes (40.00%) with posterior zone one were cured and retinopathy progress in 12 eyes (60.00%). The difference of progress rate between anterior and posterior zone one was statistically significant（chi;2=5.15, P＜0.05).Conclusions Laser photocoagulation is effective for treatment of zone one ROP, the prognosis of anterior zone one is better than posterior zone one; retinopathy progress after photocoagulation was associated with extent of fibrovascular organization.
目的:探讨双猪尾型输尿管内支架(Double pigtail stent,DPS)作为泌尿外科上尿路疾病手术辅助治疗的适应症、并发症及并发症的治疗。方法:总结我院2004年6月至2008年12月共122例施行输尿管内支架放置术患者的适应症、并发症及并发症的治疗结果。结果:24例患者(19.6%)在置管期间出现1个或以上并发症。主要并发症包括肉眼血尿(9例)、疼痛(16例)、膀胱刺激征(12例)、高热(1例)。大部分并发症是轻微和可以耐受的,并迅速得到了适当的处理。2例须拔除内支架,其中剧烈疼痛1例、高热1例。结论:DPS用于上尿路疾病手术辅助治疗是安全和有效的,DPS引起的并发症大部分易于处理。
