In the four placebo-controlled studies evaluating radiofrequency denervation outcomes in patients with "confirmed"l-z joint pain, the only study that screened patients with MBB demonstrated positive outcomes,157versus only one of three that used diagnostic intraarticularin jections.158–160 Ultrasound-guided medial branchand intraarticular blocks have also been demonstrated to provide comparable accuracy to fluoroscopically guided injections, although they may be less likely to detect low-volume intravascular uptake and are less accurate in obese patients.161–164 Because MBB are technically easier to perform than intraarticular injections and involve anesthetization of the nerves to be lesioned, it seems more logical to use these blocks as a prognostic tool before radiofrequency denervation.

在四个设有安慰剂对照的对于&确诊&小关节疼痛的患者行射频神经消融后的结果的研究中，唯一一个用MBB筛选研究对象的实验表现出阳性结果，而其他3个用关节内注射筛选的实验中只有1个表现出阳性。超声介导下的内侧支关节囊内阻滞被证实较透视介导更精确，虽然其血管内吸收剂量较低且在肥胖的患者中精确性较差。由于MBB较之关节内注射技术上更简单，且能对受损神经进行麻醉，利用这种阻滞作为神经射频消融前的诊断方法较为合理。

To test the hypothesis, neontal rat cadiomyocytes Treat with heat shock(HS,42℃,2h) to induce the expression of HSP70,then teated with 0.5mmol/L H2O2. We first found H2O2 can reduced cadiomyocytes apoptosis and HSP70 only over-expression in the HS group, other two group only express HSP70 a little in the test of expression of HSP70.Then we tested the concentration of Ca2+, the [Ca2+ ] of CON was 192.224+6.654, the [Ca2+ ] of H2O2 group was 290.6918+8.922and the [Ca2+]of HS group was 214.2633+4.484.To further determine how HSP70 repaired the Ca2+ homestasis, we measured calcium transient of each group.

实验中应用MTT和流式细胞技术检测细胞的凋亡，发现损伤组的存活率明显低于其他2组，热休克组(Heat shock group，HS group)细胞存活率略低于正常组细胞；免疫组化结果表明只有在HS组才检测到阳性反应，即是HSP70的表达，其他2组均为弱阳性结果；应用离子成像技术对细胞内钙离子浓度进行测定，发现损伤组290.6918+8.922明显高于正常组192.224+6.654和HS组214.2633+4.484，HS组细胞内的钙离子浓度略高于正常组；为了进一步探讨HSP70对于ROS引起的心肌凋亡过程中钙离子的调控机制，又对各组的心肌细胞进行了钙瞬变的测定。
