大鼠脊髓5-羟色胺1A受体和1C/2受体亚型参与高频电针镇痛 总被引:1,自引:0,他引:1
通过脊髓蛛网膜下腔慢性埋植导管分别注射5-HT受体的多种拮抗剂,分析了大鼠脊髓5-HT受体的三个主要类型5-HT1、5-HT2和5-HT3受体在高频电针镇痛中的作用。实验结果表明:i.t.注射5-HT1A受体拮抗剂spiperone25μg不影响100Hz电针的平均针效(P>0.05),但可阻断电针后效应(P<0.01);i.t.注射5-HT1c/2受体拮抗剂mianserin50μg可阻断100Hz电针的平均针效,也可阻断电针后效应(P<0.01);i.t.注射5-HT2受体拮抗剂1-NP20μg和5-HT3受体拮抗剂ICS205-930100μg对100Hz电针镇痛没有显著影响(P>0.05)。提示大鼠脊髓5-HT1A受体和5-HT1c/2受体参与介导100Hz电针镇痛,而5-HT3受体可能不起主要作用。 相似文献

BackgroundReconstruction after total sacrectomy is a difficult problem in the field of orthopedic oncology. Current reconstruction methods have not completely solved the problems associated with instrumentation failure. The purpose of this study was to evaluate the biomechanical properties of a 3D-printed total sacrum prosthesis and to conduct biomechanical comparisons between the total sacrum prosthesis and rod-screw systems for lumbosacral reconstruction after total sacrectomy.MethodsThree types of reconstruction were explored, and corresponding finite element models were simulated: four-rod reconstruction, four-rod plus anterior column reconstruction, and 3D-printed total sacrum prosthesis reconstruction. A vertical load of 600 N was applied to the L4 vertebra, and the bilateral acetabula were set as the boundary with six degrees of freedom fixed, simulating the bipedal standing position.FindingsThe order of the reconstructions according to decreasing maximum von Mises stress was as follows: four-rod reconstruction > four-rod plus anterior column reconstruction >3D-printed total sacrum prosthesis reconstruction. The order of reconstructions according to decreasing L5 shift-down displacement was as follows: four-rod reconstruction >3D-printed total sacrum prosthesis reconstruction > four-rod plus anterior column reconstruction.InterpretationCompared with the rod-screw systems, the total sacrum prosthesis reconstruction has the biomechanical advantages of a more uniform stress distribution, a lower peak stress and better stability and can thus serve as an alternative choice for reconstruction after total sacrectomy. 相似文献

背景:模拟骶骨骨折S2椎弓根钉外进钉固定拔出力与在拔出椎弓钉时的应变电测分析鲜有报道。目的:测量S2椎弓根外进钉固定拔出力与骶骨应变分布,为临床提供生物力学参数。方法:取正常国人新鲜尸体骶骨标本,以椎弓根钉外进钉方法固定于S2椎弓根,以小型力传感器与椎弓根钉固定装置连接测量椎弓根钉的拔出力,同时以动静态电阻应变仪,对预先粘贴在4个椎弓根螺栓固定边缘部位和骶骨不同部位的应变片进行应变电测量。1号进钉点位置为左侧第1骶后孔下缘最低点,2号进钉点位置为右侧第1骶后孔下缘最低点,3号进钉点为左侧第1骶后孔连线与骶外侧嵴的交点,4号进钉点为右侧第1骶后孔连线与骶外侧嵴的交点。测量椎弓根螺钉最大拔出力和骶骨各测点应变值。结果与结论:外进钉1号螺钉拔出力为(399.0±7.2)N,2号螺钉拔出力为(281.0±5.2)N,3号螺钉拔出力为(196.0±4.3)N,4号螺钉拔出力为(220.1±4.6)N。应变电测量最小应变发生在2号螺钉8号测点,应变为(13.5±1.1)με;最大应变发生在1号螺钉1号测点,应变为(96.8±6.5)με。提示S2椎弓根钉外进钉固定方法符合生物力学原理。 相似文献

Isolated fractures of the distal sacrum are usually caused by direct trauma. Undisplaced fractures are easily missed on conventional X-ray films. CT scans can disclose the full extent of the fracture. Undisplaced, or minimally displaced fractures can be treated conservatively with analgesics and a restriction to seat for six weeks. In cases of major displacement or neurological symptoms, a digital transanal reduction of the fracture under local or regional anaesthesia can be attempted. If this manoeuvre fails, open reduction and internal fixation are required. Stabilisation is challenging because of the thin bone and the complex shape of the sacrum. In a 15 year old girl with major horizontal displacement and comminution of S4, following a snowboard accident, we achieved sufficient and stable fixation with the new LCP (Locking Compression Plate) system. For six weeks after the operation, the patient was not allowed to sit down. Thereafter, she was free of pain and unrestricted in daily activities and sport. The LCP system has a number of advantages in the fixation of fractures in osteoporotic or thin bone, but clinical experience/skill and careful planning of the operation are crucial. 相似文献

【目的】采用极限加载实验对滑槽钉生长棒内固定系统与通用脊柱内固定系统的进行比较,为该系统的进一步改进及将来的临床应用提供理论依据。【方法】将新鲜猪脊柱标本12具,共3个胸椎功能单位,随机分成两组,滑槽组(固定螺钉固定标本第3椎体,滑槽螺钉固定标本第1椎体),固定组(固定螺钉固定标本1、3椎体),分别应用通用脊柱内固定系统和滑槽钉生长棒内固定系统测试标本在前屈状态及旋转状态的极限加载。所得数据采用SPSS 18.0软件进行统计学分析。【结果】前屈状态时滑槽组在400 N左右出现钉道松动,固定组在1800 N左右出现钉道松动,两组相比较差异有显著性( P<0.05);旋转状态时滑槽组在5度左右出现钉道松动,固定组在10度左右出现钉道松动,两组相比较差异有显著性(P<0.05)。【结论】滑槽钉生长棒内固定系统的极限加载要小于通用脊柱内固定系统,说明滑槽钉生长棒内固定系统的研究存在一定不足,需进一步优化,增加固定强度。 相似文献

背景:骨质疏松患者置入椎弓根螺钉后,易发生螺钉松动和复位矫正丢失等固定不稳现象,因此,骨质疏松被认为是椎弓根螺钉的相对禁忌证。目的:观察骨质疏松患者提高椎弓根螺钉稳定性方法的临床应用效果。
方法:34例骨质疏松患者行椎弓根螺钉内固定,术中采用了提高椎弓根螺钉稳定性方法。骨折患者14例(骨折组),骨病患者20例。20例骨病患者和5例骨折患者行脊柱后外侧或椎间植骨融合(融合组)。骨质疏松按Jikei分级,初级8例,Ⅰ级11例,Ⅱ级8例,Ⅲ级7例。对19例初级和Ⅰ级骨质疏松患者,采用较粗和较长螺钉,同时结合采用螺钉与连接棒强直性连接,且有两根横向连接装置,左右、上下椎弓根螺钉分别在水平面和矢状面以较大成角置入螺钉等方法提高螺钉固定相对稳定性对15例Ⅱ级和Ⅲ级骨质疏松患者,钉道注入骨水泥以提高螺钉固定绝对稳定性。结果与结论:随访9-26个月,平均14个月,无螺钉断裂,骨折组仅2例Jikei Ⅰ级患者固定后五六个月时发生螺钉松动、部分复位矫正丢失等固定不稳,但无明显其他不良影响。骨折组复位矫正丢失平均5%,融合组植骨融合率100%。对于骨质疏松患者,根据骨质梳松程度采用不同的提高螺钉固定稳定性方法,可以减少螺钉松动和复位矫正丢失等固定不稳并发症。 相似文献

ContextTraditional treatment of sacrum osteoporotic fractures is mainly based on antalgics and rest in bed. But complications are frequent, cutaneous, respiratory, thrombotic or digestive and mortality at 1 year significant.The aimsWe wanted to define the interest of sacroplasty when treating osteoporotic fracture of sacrum.MethodWe reviewed literature while studying a clinical case in an elderly patient.ResultsSacroplasty was efficient at short and mean delay to control the pain due to osteoporotic sacrum fracture. Rate of complications is low in the centers mastering the procedure.ConclusionSacroplasty is of evident interest for elderly patients suffering of an osteoporotic fracture of sacrum. It reduces decubitus complications, secondary effects of antalgics and allows an early reeducation. 相似文献
