Clinical effects of Angle's Ⅱ1 cases in Alignment with Incognito System

Objective The aim is to reveal the dentofacial changes of Angle Ⅱ1 cases during alignment phase using Incognito lingual orthodontic appliance. Methods Nineteen patients (8 Male and 11 female, aging from 12y to 23y) with Angle Ⅱ1 malocclusion were selected for lingual orthodontic treatment with four premolars extraction. Customized lingual orthodontic appliance (IncognitoTM) was used. Cephalometric radiographs and alginate impressions were taken before treatment and at the end of alignment. The comparison between pre-treatment and post-alignment were analyzed by Paired-Sample Wilcoxon Signed Rank Test through SPSS Statistical Package.Results From the Cephalometric analysis, the following changes were found significantly different (P＜0.05). U1/SN decreased 7.70°. U1/NA decreased 7.94°with 2.85 mr. L1/NB decreased 4.60°with 1.8mm. MP/SN increased 1.52°. L6-MP increased 0.51 mm. L1-MP decreased 1.29mm. OB decreased 1.18mm. From the model analysis, the following changes with significant differences were demonstrated. Upper and lower intercanine widths and lower intermolar widths increased 2.39mm,2.60mm and 1.26mm respectively. Upper arch depth from molar to incisor decreased 2.42mm. The curve of spee became shallow by 1.11mm. Conclusion During alignment phase, the upper and lower incisors tipped lingually with profile improved. The overbite decreased with lower incisors intruded, and the lower molars extruded with mandibular plane angle increased. It implied that lingual appliance would be helpful for lower angle cases with deep overbite, and cautions should be taken from the initial phase during lingual orthodontic treatment in high angle cases.     

内镜辅助导管改道术治疗唾液腺导管重度狭窄

目的:探索内镜辅助导管袋形改道术治疗唾液腺导管重度狭窄(或闭锁)并发导管重度扩张的疗效.方法:2010年7月至2016年12月对腮腺导管前段重度狭窄的患者(8例)及下颌下腺导管前段闭锁的患者(3例)行内镜辅助导管袋形改道术.所有患者患侧腺体伴发导管重度扩张,并有反复肿痛史.术前通过唾液腺造影、CT或B超测定导管扩张和狭窄情况.通过颊黏膜或口底切口将导管扩张段切开并与口腔黏膜缝合,形成改道口.术后定期复查,通过分析临床表现、造影表现及单腺体唾液流率评价疗效.结果:术前测量腮腺患者导管狭窄段长度 5～12 mm,扩张段直径8 ～ 16 mm;下颌下腺患者导管闭锁段长度10～20 mm,扩张段直径6～8 mm.所有患者术后 2周改道口愈合良好,术后随访6 ～78个月(中位数24个月).8例腮腺患者中2例导管闭锁病例术后3个月导管再次闭锁,分别随访半年、6.5年临床症状消失,且颊部索条状包块消失;1例术后症状消失,但半年后复发,可自行按摩缓解;余5例患者临床症状及颊部索条状包块消失,分泌良好,造影显示导管扩张情况改善.3例下颌下腺患者症状消失,分泌良好;其中2例造影表现良好,1例造影表现有改善.9例管口通畅的患者进行了唾液流率测定,结果显示静息状态下患侧腺体分泌良好,酸刺激后分泌增加,但稍低于健侧.11例患者临床疗效评价为优5例,良 4例,差2例,总优良率82％(9/11).结论:内镜辅助导管改道术对唾液腺导管重度狭窄(或闭锁)并发重度扩张病例具有确切疗效.     

维护足踝功能位护理模式临床研究

目的：探讨有效维护骨伤患者足踝功能位、增加舒适度的护理模式。方法：将120例需维护足踝功能位骨伤患者随机分为观察组和对照组各60例,观察组采用维护足踝功能位护理模式进行护理,对照组采用传统护理模式进行护理。观察两组患者足踝功能位保持程度及舒适度。结果：两组患者足踝功能位保持程度、舒适度比较差异有统计学意义（P〈0．01）。结论：采用维护足踝功能位护理模式,可有效地保持足踝功能位,提高患者舒适度。     

髂腹下神经、髂腹股沟神经和生殖股神经变异1例

国内外文献中关于髂腹下神经、髂腹股沟神经或生殖股神经的变异包括起源、行程、数目、分支分布等诸多情况[1～4].作者在解剖1具青年女性尸体时,发现其髂腹下神经、髂腹股沟神经和生殖股神经分支或分布都有异常.该变异尚未见文献报道.     

哌拉西林/他唑巴坦治疗泌尿系感染210例临床分析

目的 评价哌拉西林/他唑巴坦在治疗泌尿系感染时的疗效、安全性和经济性.方法 采用回顾性分析方法,210例患者其中156例应用哌拉西林/他唑巴坦治疗,2.5 g(含哌拉西林2.0g和他唑巴坦0.5 g),1次/12 h,静脉滴注;54例应用头孢哌酮/舒巴坦治疗,2.0g,1次/12 h,静脉滴注,根据卫生部新药临床研究指导原则标准判定疗效.结果 应用哌拉西林/他唑巴坦和头孢哌酮/舒巴坦治疗泌尿系感染的临床有效率分别是87.18％和87.04％,细菌清除率为86.55％和86.84％;上述两种治疗方法相比差异无统计学意义.结论 哌拉西林/他唑巴坦治疗泌尿系感染疗效明显,而且安全性好,经济实惠.
