目的探讨彩色多普勒超声引导下股腘动脉硬化闭塞症腔内治疗的近期疗效及安全性。方法收集股腘动脉硬化闭塞症患者19例(共21条肢体),在彩色多普勒超声引导下进行腔内治疗。结果 19例患者中,重度肢体缺血(卢瑟福分级4~6级)6例,间歇性跛行(卢瑟福分级2~3级)13例。合并慢性肾功能不全12例,高血压病13例,糖尿病11例,含碘对比剂过敏2例,肾衰竭2例。21条肢体中,泛大西洋介入学会协议(TASC)A级12条、TASC B级6条、TASC C级3条。1例TASC C级病变腔内治疗失败,转开放转流手术,余18例20条肢体均治疗成功,无手术相关并发症。术前踝肱指数与术后比较差异有统计学意义(0.47±0.12vs 0.89±0.15,P0.05)。术后1个月病变段通畅率100%(20/20),术后6个月通畅率90.00%(18/20)。术后随访期间肾功能无恶化。结论对于存在对比剂肾病风险、含碘离子对比剂过敏的患者,彩色多普勒超声引导下的下肢动脉成形术是较好选择。     

产前超声监测对双胎妊娠并发症的诊断及治疗选择的价值

目的：探讨双胎妊娠的产前超声监测方法对双胎并发症的诊断及治疗选择的价值。方法回顾性分析81例双胎妊娠孕妇的临床资料和超声监测方法,综合评估是否出现双胎输血综合征（TTTS）、选择性胎儿生长受限（sIUGR）等单绒毛膜双胎（MC双胎）特有的并发症,进行相应分期、分型和监测;随访至妊娠终止。结果81例双胎妊娠中双绒毛膜双羊膜囊双胎（DCDA ）40例出现双胎之一宫内死亡1例,双胎生长不一致1例;38例单绒毛膜双羊膜囊双胎（MCDA）出现TTTS 4例,sIUGR 2例,双胎之一唇腭裂畸形1例,双胎之一宫内死亡1例;3例单绒毛膜单羊膜囊双胎（MCMA）并发双胎之一无心畸形1例,联体双胎1例。DCDA并发症明显小于MC双胎并发症（P＜0．05）。DCDA双胎丢失率1/80（胎）,MC双胎丢失率11/82（胎）。DCDA胎儿丢失率明显低于MC双胎胎儿丢失率（ P＜0．05）。产前超声监测与终止妊娠结果100％符合。结论早孕期诊断双胎妊娠的绒毛膜性具有重要的临床意义;对＜26孕周的 MC双胎每2周监测1次,可早期诊断并发症;对≥26孕周的 TTTS及sIUGR在超声严密监测下选择分娩时机,可提高MC双胎围生儿生存率。

钛合金内固定材料修复脊柱结核：生物相容性及力学性能

BACKGROUND: Currently, surgical implant fixation is mainly applied for spinal tuberculosis. How to choose implant materials, however, is still under discussion. OBJECTIVE: To compare the biocompatibility and mechanical properties of titanium alloy and stainless steel for rabbit spinal tuberculosis. METHODS: Thirty rabbits were chosen to prepare spinal tuberculosis models. Then, the rabbits were equivalently randomized into two groups, which underwent implant fixation with stainless steel or titanium alloy, respectively. At 30 days after implantation, biocompatibility and biomechanical properties of the two materials in the repaired region of spine were observed and detected, respectively. RESULTS AND CONCLUSION: In view of the biocompatibility, infection and immunological rejection could not been found in the titanium alloy group; in contrast, infection appeared in three rabbits of the stainless steel group. Flexion, extension and lateral bending displacements under the spinal loading in the titanium alloy group were significantly less than those in the stainless steel group (P < 0.05); axial pull-out strength in the titanium alloy group was significantly higher than that in the stainless steel group (P < 0.05); flexion, extension, lateral bending and axial compression in the titanium alloy group were significantly greater than those in the stainless steel group (P < 0.05). In conclusion, titanium alloy material has good biocompatibility that can be used to restore and maintain the spinal stability.     

椎弓根螺钉及颈椎体螺钉置入内固定后的生物力学及稳定性比较

BACKGROUND: From the point of view of human anatomy, the load of the spine is more. When the body moves, the range of activities, and activity are relatively large. After screws were implanted in the spine, if biomechanical properties and stability are not up to the standard, it easily leads to lack of grip force of screw and screw loosening so as to increase the incidence of complications after treatment.      

正交设计法优选骨舒乳膏基质成分的配比

目的优选骨舒乳膏基质的组成和配比。方法采用正交设计法,以乳膏离心分层时间为考察指标,通过实验对影响乳膏稳定性的主要因素进行考察,确定乳膏的最佳制备工艺。结果以硬酯酸11％,液体石蜡4．5％,单甘酯11％,白凡士林6．5％制得的乳膏最稳定。结论优选得到的配方稳定可行。
