Objective To study the diagnosis and the treatment of arachnoid cysts in the sacral canal.

①目的 探讨骶管硬膜外蛛网膜囊肿的诊断及治疗方法。

Methods Thirty-six patients with arachnoid cysts treated were analyzed retrospectively. The radiological changes including X-ray, CT and MRI, as well as their clinical behaviors, and the methods of operation were evaluated.

回顾分析36例经手术证实的骶管硬膜外蛛网膜囊肿病人的影像学资料，分析其临床特点及术中的病理特点。

The structure shown in the figure : The governing body received direct or roller drying cylinder, as the main components of the rotation; After finishing the outside of the sphere, Bottom Cover and soak spherical carbon graphite seal ring joint seal reliable seal friction deputy, Sealing ring in the spherical shell of its annular space sliding, in addition to oil-free bearings and with the close cooperation of Shell, Rotating connector so that the free support, and therefore do not require a high level of accuracy installed; Spherical seal ring wear, Spring means of pressure at any time in advance to receive compensation, compensation for the shell slowly moved backward, accessible through the tube outside the inscription on the line to observe the seals wear; When steam, Oil flows through the media or other spherical sealing ring and oil-free bearings, the formation of thin liquid film, sealing and lubrication, thereby reducing friction and wear, extending the service life.

其结构如图所示：外管体直接接到辊子或烘筒上，为主要的旋转部件；经过精加工的外管本球面、底盖和浸泡碳石墨球面密封环共同组成密封可靠的动密封磨擦副，球面密封环在其壳体内的环形空间中滑动，加之无油轴承与壳体的密切配合，使旋转接头自由支撑，故对装机精度要求不高；球面密封环磨损后，借助于弹簧的预压力随时得到补偿，补偿时壳体缓缓向后移动，并可通过外管体上的刻线观察到密封件的磨损程度；当蒸汽、油或其它介质流经球面密封环和无油轴承时，形成一层很薄的液膜，提供密封和润滑，从而减轻了摩擦和磨损，延长了使用寿命。

To 2 branches with the external diameter of (0.62~0.94)mm can he found at the medial side of the proximal end of the ulna, as well a branch of periosteum at the lateral side with the diameter of (1.58±0.16)mm at the level of the supinator, and (1.17±0.10)mm at the level of the neck of radius.

尺骨近鹰嘴段，内侧有1~2条较其它肌骨膜支粗大血管，外径0.62~0.94mm；外侧恒定有一骨膜支，在出旋后肌水平血管外径(1.58±0.16)mm，平桡骨颈水平外径(1.17±0.10)mm。

The reasons for false-positive facet blocks are multifactorial and include placebo response (18–32%) to diagnostic facet interventions, use of sedation, the liberal use of superficial LA, and the spread of injectate to paingenerating structures other than those targeted.166 Although some investigators have disputed this assertion,167,168 it is our belief that not only opioids, but sedatives such as midazolam, can lead to false-positive blocks by interfering with the interpretation of analgesic response (i.e., preventing a patient from engaging in normal activities) and virtue of their muscle relaxant properties.169 In a recent survey conducted in 500 patients receiving facet blocks or epidurals at an outpatient spine center, only 17% requested sedation.170

小关节阻滞性诊断的假阳性结果的原因是多种多样的，包括安慰剂反应(18–32%)，如利用镇静剂，浅表大量应用LA以及注射液外渗到目标外的其他疼痛发生阻滞。虽然有些学者对这种论断持怀疑态度，但是我们认为不论类罂粟碱，咪达唑仑等镇静剂，都可因具有麻醉反应（如可阻止患者从事正常活动）及肌松特点而导致假阳性率。在最近一项500人的研究中，这些门诊患者接受了小关节阻滞或硬膜外阻滞，只有17%患者需要镇静剂。

The result using inhibitors of Ca〓 channels supported above observation. When Ca〓 channels in plasma membrane were blocked by LaCl〓, verapamil or nifedipine, and the Ca〓 channels in endomembranes opened naturally, extracellular CaM couldn't induce 〓 increase. When Ca〓 channels in endomembranes were blocked by ruthenium red and the Ca〓 channels in plasma membrane opened naturally, extracellular CaM induced Ca〓 increase in guard cells, but the extent of Ca〓 increase was lower than that of control.

使用质膜Ca〓通道抑制剂LaCl〓、异博定、尼群地平及细胞内Ca〓通道抑制剂钌红的结果支持这种推测：在质膜Ca〓通道被阻断、细胞内Ca〓通道仍正常开放的情况下，保卫细胞〓不能被CaM诱导增加；细胞内Ca〓通道被抑制、质膜Ca〓通道正常开放的条件下，细胞外CaM诱导保卫细胞内〓升高的幅度不能达到不使用Ca〓通道抑制剂的水平。
