    • 摘要: 目的探讨选择性神经损伤(SNI)模型大鼠发生疼痛、抑郁样行为的可能机制,以及侧脑室注射米诺环素对其疼痛、抑郁样行为的干预效果。方法将120只成年雄性SD大鼠随机分为假手术组(Sham组)、SNI组、SNI+1μg Mino组和SNI+10μg Mino组,每组30只。SNI组、SNI+1μg Mino组和SNI+10μg Mino组大鼠在建立SNI模型后,分别给予侧脑室注射磷酸缓冲盐溶液、1μg/μL和10μg/μL米诺环素溶液,Sham组只进行假手术,不损伤及结扎神经,并于术后给予侧脑室注射磷酸缓冲盐溶液。于实验前1 d及鞘内置管术后(即术后)1 d、3 d、7 d、14 d,通过测定热缩足反射潜伏期(PWTL)评估大鼠的疼痛程度;于实验前1 d及术后1 d、7 d通过转棒试验评估大鼠的运动功能。于实验前1 d及术后1 d、7 d、14 d,采用强迫游泳实验及糖水偏好实验评估大鼠的抑郁样行为。采用免疫荧光法及蛋白免疫印迹法分析术后14 d大鼠海马组织离子钙接头蛋白1(Iba-1)的表达量,采用ELISA检测术后3 d、7 d、14 d大鼠海马组织肿瘤坏死因子α(TNF-α)表达水平及白细胞介素6(IL-6)含量。结果在术后各时间点,与Sham组相比,SNI组的PWTL缩短,强迫游泳不动时间延长,糖水偏好百分比降低,海马组织中小胶质细胞明显增殖,Iba-1蛋白的表达量、TNF-α表达水平和IL-6含量均升高(均P0.05)。结论SNI大鼠出现的神经病理性疼痛及抑郁样行为,均与海马区小胶质细胞的激活和神经炎症有着密切的联系,而侧脑室注射小胶质细胞抑制剂米诺环素可改善上述情况。

    • 摘要: Objective To evaluate the effect of intracerebroventricular injection of 7-nitroindazole (7-NI) on the depression-like behaviors in normal rats.Methods According to body weights,48 SD rats were randomly divided into normal group,model group,sham-operation group and 7-NI groups at different concentrations (n=8).The model group was treated with chronic and unpredictable mild stress.The 7-NI groups received intracerebroventricular injection with 7-NI solutions at different concentrations,once every 3 days for 3 times in total.The sham-operation group was injected with DMSO of the same volume.The rat behaviors were then subjected to the open field test (OFT).The hippocampal nNOS protein levels were detected by Western blot.Results Compared with the normal group((132.47±31.72) m),the total movement distances of model group ((15.04±8.61) m) and 200 nmol/0.5 μl surgery group((18.18± 11.82) m) decreased significantly (P< 0.05).Compared with the model group,such distances of sham-operation group ((107.33±20.35)m) and 7-NI groups(50 nmol/0.5 μl:(138.40±56.85)m,(86.97±36.20)m);100 nmol/0.5 μl:(86.97±36.20)m) increased significantly (P< 0.05).The normal group entered the central area significantly more times(2.25±2.05) than model group (0.25±0.46)and 200nmol/0.5μl 7-NI group (0.25± 0.46) did (P<0.05),and the number of times entering the central area of the model group (0.25±0.46)was significantly lower than that of the sham-operation group (1.00 ± 1.07,P< 0.05) and 50 nmol/0.5 μl group (0.75 ± 1.16).Compared with the normal group ((46.53 ±41.16) s),the durations of stay in the central area of model group ((1.27 ± 1.92) s) and 200 nmol/0.5 μl 7-NI group ((1.53 ± 2.90) s) were shortened significantly (P<0.05).Compared with the model group,the durations of stay in the central area of 100 nmol/0.5μl group ((36.54±67.80) s) was lengthened significantly (P< 0.05).Western blotting showed that the hippocampal nNOS protein levels of model group (0.43±0.11) and 200 nmol/0.5μl 7-NI group(0.56±0.08) significantly exceeded that of the normal group (0.04±0.02,P<0.05).The levels of nNOS in sham-operation group (0.04 ±0.02) and 50 nmol/0.5 μl 7-NI group (0.22± 0.08),which were significantly lower than that of the model group (0.43 ± 0.11,P< 0.05),were similar to that of the normal group (0.04 ± 0.02,P> 0.05).Conclusion Intracerebroventricular injection 200 nmol/0.5 μl 7-NI solution results in depression-like behaviors and increased the expression of nNOS protein reflexively in rats.%目的 观察侧脑室注射7-硝基吲唑(7-Nitroindazole,7-NI)对正常大鼠抑郁样行为及nNOS蛋白表达的影响.方法 雄性SD大鼠48只按体质量随机分为正常组、模型组、假手术组与不同浓度7-NI侧脑室注射组,每组8只.模型组采用慢性不可预知的温和性应激(Chronic and unpredictable mild stress,CUMS)方法进行造模处理,采用不同浓度的7-NI溶液侧脑室注射,1次/3 d,共3次.假手术组注射等体积二甲基亚砜(DMSO).通过旷场实验测试各组大鼠行为学变化,Western bolt法测定海马nNOS蛋白表达水平.结果 与正常组[(132.47±31.72) m]比较,模型组[(15.04±8.61)m]与200 nmol/0.5μl组[(18.18±11.82)m]大鼠旷场实验运动总距离显著下降(P<0.05),与模型组比较,假手术组[(107.33±20.35) m]与其余浓度手术组[(138.40±56.85)m,(86.97±36.20)m]大鼠运动总距离显著上升(P<0.05).与正常组[(2.25±2.05)次]比较,模型组[(0.25±0.46)次]与200nmol/0.5μl组[(0.25±0.46)次]大鼠中心区进入次数显著减少(P<0.05),与模型组比较,假手术组[(1.00±1.07)次]与50 nmol/0.5μl组[(0.75±1.16)次]大鼠中心区进入次数显著增加(P<0.05).与正常组[(46.53±41.16)s]比较,模型组[(1.27±2.92)s]与200 nmol/0.5μl组[(1.53±2.90)s]大鼠中心区进入时间均显著缩短(P<0.05);与模型组比较,100 nmol/0.5μl组[(36.54±67.80)s]大鼠中心区进入时间显著增加(P<0.05).Western bolt结果显示,模型组(0.43±0.11)与200 nmol/0.5μl组大鼠海马nNOS蛋白表达水平(0.56±0.06)显著高于正常组(0.04±0.02)(P<0.05),与模型组比较,假手术组(0.04±0.02)与50 nmol/0.5μl组(0.22±0.08)大鼠nNOS蛋白表达水平下降,差异有统计学意义(P<0.05).结论 侧脑室注射200 nmol/0.5μl浓度7-NI导致大鼠发生抑郁样行为,nNOS蛋白表达反射性增加.

    • 摘要: 缺血性脑卒中缺乏有效的治疗措施,目前应用于临床的许多药物受到血脑屏障的限制,难以充分发挥疗效.EGb 761是银杏制剂的提取物,在改善心脑血管疾病方面积累了大量证据.为提高其局部血药浓度,我们采用侧脑室微量泵泵入EGb 761,并观察其对大脑中动脉缺血-再灌注(MCAO)大鼠脑区细胞凋亡的影响,探讨其作用机制及侧脑室注射途径的可行性.

    • 摘要: 为探究侧脑室注射Nesfatin-1对雌性大鼠促性腺激素水平及其mRNA表达的影响,对初情期前雌性大鼠的侧脑室注射Nesfatin-1,采用实时荧光定量PCR法检测促黄体素(Luteinizing hormone,LH)和促卵泡素(Folliclestimulating hormone,FSH) mRNA在垂体中的变化,采用酶联免疫分析法检测血清LH和FSH的浓度.结果表明:在初情期前的雌性大鼠中,Nesfatin-1可促进初情期启动、增加卵巢重量、血清LH水平、垂体LH mRNA和FSH mRNA的表达增加(P<0.05);但Nesfatin-1对FSH水平的影响不突出,注射后15 min时增加(P<0.05),60 min不产生影响(P>0.05).侧脑室注射Nesfatin-1后15和60 min均能提高血清LH水平,15 min时提高更明显(P<0.05),但对FSH水平的影响不尽相同.在成年的雌性大鼠中,Nesfatin-1对LH和FSH的分泌不产生影响(P>0.05).Nesfatin-1可通过下丘脑诱导和增强初情期过渡阶段雌性大鼠LH和FSH的释放及LH、FSH mRNA的表达.

    • 摘要: 目的:观察中枢nesfatin-1对大鼠夜间摄食和胃排空的影响.方法:大鼠经腹腔注射硫酸仲丁巴比妥(100~150 mg/kg)麻醉,侧脑室、第四脑室或小脑延髓池注射nesfatin-1或CRF受体拮抗剂astressin-B或astressin2-B,观察对摄食、胃排空的影响.结果:侧脑室注射nesfatin-1后大鼠第3-6 h夜间进食量(t=3.05~3.58,P<0.01)和3h和6h的累积进食量(t=5.90~12.1,P<0.01)明显减少,nesfatin-1的该抑制效应可被预先侧脑室注射astressin-B或astressin2-B阻断(t=1.06~2.22,P<0.05).第四脑室或小脑延髓池注射nesfatin-1后大鼠夜间摄食量在第1h就明显减少(t=2.59~6.26,P<0.05~0.01),持续减少至5-6h(t=1.69~7.42,P<0.05~0.01).侧脑室注射不同剂量nesfatin-1(0.05或0.5 μg)20 min后GE率明显降低,且随注射剂量增大,GE率越低(t=3.25~4.67,P<0.01).若预先给予大鼠CRF受体拮抗剂astressin2-B(30 μg)再注射nesfatin-1(0.5 μg),nesfatin-1抑制大鼠胃排空效应明显减弱(t=2.45~2.85,P<0.05).禁食24h后再喂食2h,大鼠下丘脑中nesfatin-1表达明显增加(t=2.87,P<0.05),禁食24h后血浆nesfatin-1水平明显降低(t=1.51,P<0.05).结论:Nesfatin-1抑制摄食作用可能由nesfatin-1和CRF2信号系统共同调节.
