疏血通脉汤联合傍针刺对中风后肩手综合征患者肢体痉挛、血液流变学及活动能力的影响

目的:探讨疏血通脉汤联合傍针刺治疗中风后肩手综合征(shoulder-hand syndrome after stroke,SHSAS)的临床疗效,并观察其对患者上肢肢体痉挛程度、血液流变学以及上肢活动能力的影响。方法:110例痰瘀阻络型SHSAS患者按照随机数字表法分为对照组与联合组,每组55例。两组患者均给予神经内科常规药物和肢体功能康复训练治疗。对照组联合傍针刺法治疗,联合组在对照组治疗基础上给予疏血通脉汤。两组患者均以4周为1个疗程,治疗1个疗程。记录比较两组患者治疗前后上肢肢体痉挛程度(Ashworth)、上肢活动能力(FMA)、肩手综合征量表(shoulder hand syndrome scale,SHSS)、视觉模拟评分(visual simulation scoring,VAS)、中医证候评分,高切全血黏度、低切全血黏度、血浆黏度和血小板聚集率等血液流变学指标,并比较治疗效果。结果:联合组有效率为96.36%,对照组有效率为83.64%,两组患者有效率比较,差异有统计学意义(P0.05)。治疗后,联合组高切全血黏度、低切全血黏度、血浆黏度与血小板聚集率水平均低于对照组,差异有统计学意义(P0.05);联合组Ashworth评分低于对照组、上肢FMA评分高于对照组,差异有统计学意义(P0.05);联合组SHSS评分和中医证候评分均低于对照组,差异有统计学意义(P0.05);联合组VAS评分低于对照组,差异有统计学意义(P0.05)。结论:疏血通脉汤联合傍针刺治疗SHSAS患者疗效显著,能有效改善患者血液流变学,缓解疼痛程度和上肢痉挛,提高上肢活动能力。

Mixed Reality Combined with Three‐Dimensional Printing Technology in Total Hip Arthroplasty: An Updated Review with a Preliminary Case Presentation

Three‐dimensional (3D) printing technology, virtual reality, and augmented reality technology have been used to help surgeons to complete complex total hip arthroplasty, while their respective shortcomings limit their further application. With the development of technology, mixed reality (MR) technology has been applied to improve the success rate of complicated hip arthroplasty because of its unique advantages. We presented a case of a 59‐year‐old man with an intertrochanteric fracture in the left femur, who had received a prior left hip fusion. After admission to our hospital, a left total hip arthroplasty was performed on the patient using a combination of MR technology and 3D printing technology. Before surgery, 3D reconstruction of a certain bony landmark exposed in the surgical area was first performed. Then a veneer part was designed according to the bony landmark and connected to a reference registration landmark outside the body through a connecting rod. After that, the series of parts were made into a holistic reference registration instrument using 3D printing technology, and the patient's data for bone and surrounding tissue, along with digital 3D information of the reference registration instrument, were imported into the head‐mounted display (HMD). During the operation, the disinfected reference registration instrument was installed on the selected bony landmark, and then the automatic real‐time registration was realized by HMD through recognizing the registration landmark on the reference registration instrument, whereby the patient's virtual bone and other anatomical structures were quickly and accurately superimposed on the real body of the patient. To the best of our knowledge, this is the first report to use MR combined with 3D printing technology in total hip arthroplasty.     

不同波形低频率电刺激对小鼠海马电点燃癫痫的作用比较

目的观察比较不同脉冲波形的低频率电刺激对海马电点燃癫痫模型小鼠的作用差异。方法采用电点燃刺激法建立小鼠癫痫模型, 观察正弦波、单相方波、双相方波低频率电刺激对模型小鼠癫痫行为发作及后放电持续时间的影响, 并比较不同时间点给予正弦波低频率电刺激的抗癫痫作用。结果与对照组比较, 正弦波低频率电刺激30 s能降低小鼠海马电点燃癫痫发作等级(2.85 ± 0.27 vs 4.75 ±0.12, P < 0.05)、减少大发作概率(53.6% vs 96.5%, P < 0.01) 和缩短后放电持续时间[(16.22 ± 1.69) s vs (30.29 ± 1.12) s, P < 0.01], 而单相方波和双相方波低频率电刺激30 s没有明显的抗癫痫作用。常用的单相方波低频率电刺激15 min能降低小鼠海马电点燃发作等级(3.58 ± 0.16, P < 0.05)、减少大发作概率(66.7%, P < 0.01);但对海马后放电持续时间及大发作持续时间无影响(均 P>0.05)。此外, 电点燃刺激前预先给予或结束后3 s内给予正弦波低频率电刺激具有明显的抗癫痫作用( P < 0.05或 P < 0.01), 而电点燃刺激结束10 s给予正弦波低频率电刺激则无上述抗癫痫作用。 结论低频率电刺激抗癫痫作用受波形参数的影响, 其中正弦波低频率电刺激能有效抑制小鼠海马电点燃癫痫的发作。
