    • 摘要: 目的 研究鞘内注射细胞外调节蛋白激酶(ERK1/2)抑制剂(SCH772984)对骨癌痛Sprague-Dawley(SD)大鼠疼痛行为学及脊髓背角Fos蛋白表达的影响,探讨ERK-P90RSK-Fos信号通路在骨癌痛中的作用.方法 取鞘内置管后5天的雌性SD大鼠40只,随机分成5组(n=8),包括Sham假手术组和BNP模型组(分别为对照组,SCH772984给药组SCH 0.1组,SCH 1组,SCH 10组).在造模后第9天,Sham组不给药,BNP模型组鞘内分别给5% DMS0 10μl、SCH772984抑制剂0.1、1.0、10μg(SCH772984抑制剂溶于10μl 5%的DMSO中).测定造模前1天、造模后3、6、9、12、15、18天以及给药后1、3、6、9、12、18、24h的机械缩足阈值(MWT)、热缩足潜伏期(PWL)以及2min自发缩足次数.取鞘内置管后5天的SD大鼠40只,随机分为5组(n=8),其中B1、B2、B3组在造模后第9天,鞘内注射SCH772984抑制剂10μg后分别于1、9、24h取材,M组为模型对照组,鞘内注射5% DMSO后9h取材,S组为空白对照组.通过免疫印迹(Western blot)法及免疫荧光测定脊髓背角p-ERK、p-p90RSK以及Fos蛋白表达情况.结果 鞘内注射ERK1/2抑制剂(SCH772984)对骨癌痛大鼠有镇痛作用,并且该效应随着剂量的增加而增大;鞘内注射ERK1/2抑制剂(SCH772984) 10μg可明显减少脊髓背角Fos蛋白的表达.结论 ERK-p90RSK-Fos通路可能影响骨癌痛.%Objective To investigate the effect of Intrathecal injection of ERK1/2 inhibitor (SCH772984) on the behaviors of analgesic effect in rat with bone cancer pain and the expression of Fos protein in spinal dorsal horn,and the role of ERK-P90RSK-Fos signaling pathway played on rat with bone cancer pain.Methods Forty female SD rats after taken intrathecal catheter were randomly divided into five group (Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ) (n =8).Sham-operated group (Ⅰ),BNP model groups (Control group and different dosage group:SCH 0.1 group,SCH 1 group,SCH 10 group).Nine day after model establishment,group Ⅰ was treated without drug,group Ⅱ,Ⅲ,Ⅳ,Ⅴ were treated with 5% DMSO 10μl,SCH772984 inhibitor 0.1,1.0 and 10μg(SCH772984 inhibitor melted in 10μl 5% 的 DMSO).Mechanical withdrawal threshold (MWT),thermal withdrawal latency (PWL) and spontaneous flinching times (2 mninutes) were measured before model establishment (1day) and before model establishment (3,6,9,12,15 and 18 day) and treated with drug (1,3,6,9,12,18 and 24h).40 female SD rats after taken intrathecal catheter were randomly divided into five group (B1,B2,B3,M and S) (n =8).B1,B2 and B3 groups treated with model establishment (9 day).Intrathecal injection was performed with SCH772984 inhibitor 10μg and samples was collected in 1,9 and 24h.M group was model group.Intrathecal injection was performed with 5% DMSO and samples was collected in 9h.S group was blank group.Western blot and immunofluorescence were used to detect the protein expression of p-ERK,p-p90RSK and Fos.Results Intrathecal injection of ERK1/2 inhibitor can play roles of analgesic effect in rats with bone cancer pain,and the effect increased with the increase of the ERK1/2 inhibitor dose.Intrathecal injection of ERK1/2 inhibitor (SCH772984) 10μg can significant decreased the protein expression of Fos in spinal dorsal horn.Conclusion ERK-p90RSK-Fos signaling pathway can participate in the regulation of bone cancer pain.

    • 摘要: c-fos基因是一种存在于正常神经核内的原癌基因,具有高度保守性.c-fos基因当机体受到外界刺激时,c-fos基因便迅速表达,通过转录和翻译等一系列过程形成Fos蛋白.麻醉药的使用会影响中枢神经系统中c-fos基因的表达,可以根据c-fos基因的转录和翻译情况从基因和蛋白质的水平研究麻醉药的麻醉机理,这为麻醉药的研究提供了一个思路.

    • 摘要: 目的:研究截断尾末端能否引起小鼠扣带回前部(ACC)神经元Fos蛋白表达的改变,以及NK⁃1受体在该变化中的作用。方法用免疫组化技术研究截断小鼠尾末端2.5 cm后0.25 h、0.5 h、1 h和2 h ACC神经元Fos蛋白表达的变化,以及GR82334 NK⁃1受体拮抗剂尾静脉、蛛网膜下腔注射对该变化的影响。结果截断小鼠尾末端后0.25 h和0.5 h ACC神经元Fos蛋白表达显著增加,1 h达高峰,2 h后开始消退;GR82334尾静脉注射完全拮抗了截断小鼠尾末端引起的ACC神经元Fos蛋白表达的显著增加,但GR82334蛛网膜下腔注射拮抗作用不完全。结论截断小鼠尾末端能够引起ACC神经元Fos蛋白表达呈时间依赖性显著增加;外周与中枢NK⁃1受体参与此过程,但是,尚存其他受体和递质参与的中枢传导通路引起ACC神经元Fos蛋白表达的显著增加。%Objective To study whether amputation of the tail extremity could induce change of Fos protein expression in mice ACC neurons , and explore the role of NK⁃1 receptor in the change. Methods Immunohistochemistry technique was adopted to study Fos protein expression change in mice ACC neurons at 0.25 h,0.5 h,1 h,2 h after amputation of the tail extremity 2.5 cm,and also the effect of NK⁃1 receptor antagonist GR82334(iv)or GR82334(ith)in the change. Results Fos protein expression in mice ACC neurons was significantly increased at 0.25 h,0.5 h after the amputation,and reached its peak at 1 h after the amputation,then started to decrease at 2 h after the amputation. GR82334(iv)com⁃pletely antagonized the significant augment in Fos protein expression in mice ACC neurons after the amputation ,but the antagonism of GR82334 (ith)was incomplete. Conclusion Amputation of the tail extremity could significantly increase the Fos protein expression of mice ACC neurons in a time⁃dependent manner. Both peripheral and central NK⁃1 receptors were involved in the process. However ,there are also central conduction pathways of other receptors and neurotransmitters involved in the significant augment in Fos protein expression in mice ACC neurons after amputa⁃tion.

Methods A total of 48 male SD rats were randomly divided into six groups:Naive group,Sham group ( just separated the left sciatic nerves without liga⁃tion) ,CCI group ( the left sciatic nerve was ligated) ,CCI+P group ( on the 14 th day after surgery,intraper⁃itoneal injection of 10 mg/kg paroxetine 45 min before behavior test) ,ACC⁃Sham group ( bilateral microin⁃jection of 0.9% NaCl in ACC,1μl/each side) and ACC⁃AP5 group ( bilateral microinjection of AP5 25 mM in ACC,1μl/each side on the 13th day after surgery) . On the 14th day after light⁃dark transition test,forced swimming test,paw⁃withdrawal mechanical threshold( PWMT) and paw⁃withdrawal thermal patency( PWTL) were performed,the rats were terminally anesthetized and ACC,PAG,RVM and the spinal cord was rapidly removed,and then the expression of c⁃fos was measured by immunohistochemistry. Results ( 1) Rats in CCI group demonstrated nociceptive hypersensitivity and depressive⁃like behaviors compared with Naive rats, while rats in CCI+P group and in ACC⁃AP5 group showed less nociceptive hypersensitivity and less depres⁃sive⁃like behaviors compared with CCI group. (2)Compared with Naive group,the number of c⁃fos positive neurons in the bilateral ACC (left,surgery side,4920.6±1053.7;right,2059.3±409.1),VIPAG (9074.8± 2320.3),RVM (6195.4±895.0) and bilateral spinal cord (left,15148.8±3080.2;right,6400.2±1558.4) was significantly enhanced in CCI group, especially in the left side. In contrast, the amount of fos labeled neurons declined in the bilateral ACC (left,2776.4±820.1;right,1120.5±141.4),VIPAG (4002.2± 1171.8),RVM (2938.9±910.3) and bilateral spinal cord (left,8742.0±1131.0;right,3933.1±858.9) in CCI+P group and also declined in the bilateral ACC (left,3623.1±667.4;right,696.5±164.8),VIPAG (5668.8±1403.3),RVM (3972.3±851.7) and bilateral spinal cord (left,10675.4±1725.3;right,3818.3± 1085.1) in ACC⁃AP5 group. Conclusion Endogenous descending facilitatory system may contribute to ACC modulating spinal nociceptive transmission.
