门静脉淤血对肠源性内毒素血症及肝脏缺血再灌注损伤的影响

目的 探讨门静脉淤血对肠源性内毒素血症及肝脏缺血再灌注损伤的影响.方法 检测家兔肝脏原位冷灌注30 min后淤血的门静脉中内毒素含量,观察清除门静脉淤血对血清内毒素、丙氨酸转氨酶(ALT)、透明质酸(HA)、肝组织匀浆丙二醛(MDA)含量、超氧化物歧化酶(SOD)活性及肝脏组织学改变的影响.结果 门静脉阻断30 min后,每去除2.5 ml淤血可使血清内毒素含量显著下降(F=52.698,P＜0.01),但去除7.5 ml后淤血中内毒素含量不再明显下降(F=1.243,P＞0.05).去除门静脉淤血能降低复流后血清内毒素、ALT、HA和肝组织匀浆中MDA,SOD含量,改善肝脏病理学变化.其中,去除门静脉淤血在5 ml与10 ml时效果最为明显,与不去除相比较差异有统计学意义(F=4.835,P＜0.05);去除门静脉淤血2.5 ml、15 ml时与不去除相比较差异无统计学意义(F=2.275,P＞0.05).结论 首批放出的5 ml门静脉淤血中内毒素含量极高,可能是引起肝脏损伤的主要原因;放掉门静脉淤血可以减轻肠源性内毒素血症和肝脏缺血再灌注损伤.     

中医对脊柱相关疾病中眩晕与腰痛的认识

脊柱相关疾病是指颈、胸、腰椎的骨关节、椎间盘及椎周围软组织遭受损伤或退行性改变，在一定诱因条件下发生脊柱小关节错位、椎间盘突出、韧带钙化或骨质增生，直接或间接对神经根、椎管内外血管、脊髓或交感神经等产生刺激或压迫，导致脊椎损伤疾患以外的多系统症状和体征的疾病。本文将对眩晕和腰痛从中医的病因病理、与经络的关系、治疗方法等方面做一综述。

鞘内注射吗啡加可乐定对切口痛大鼠脊髓背角蛋白激酶A催化亚单位表达的影响

Objective To observe the effect of intrathecal clonidine plus morphine on expression of protein kinase A (PKA) catalytic subunit in the spinal dorsal horn in a rat model of incisional pain. Methods Eighty male Sprague-Dawley rats were divided randomly into five groups: sham group, control group, pre-incisional morphine 2.5 μg group, pro-incisional clonidine 5 μg group and preincisional morphine 2.5 μg plus clonidine 5 lag group (n=16). lntrathecal catheter and the model of incisional pain were pro-duced according to Yaksh and Brennan's described method respectively. Changes of pain behavior were assessed by mechanical with-drawal threshold (MWT) and thermal withdrawal latency(TWL). The expressions of PKA catalytic subunit in the spinal dorsal horn were assessed by immunohistochemical method and western blotting analysis. Results Compared with sham group, MWT and TWL in control group were decreased significantly at 2 h after incision (P<0.01) and the number of positive cells and protein expression of PKA catalytic subunit in the spinal dorsal horn were increased significantly in control group (P<0.01). Compared with control group, MWT and TWL in pre-incision morphine 2 μg plus clonidine 5 lag group were increased significantly at 2 h after incision (P<0.01) and the number of positive cells and protein expression of PKA catalytic subunit in the spinal dorsal horn were decreased significantly in pre-incision morphine 2 μg plus clonidine 5 μg group (P<0.01). However, MWT, TWL and the number of positive cells and pro-tein expression of PKA catalytic subunit in the spinal dorsal horn changed with no statistical significance in pre-incisional morphine 2.5 μg group and pre-incisional clonidine 5 μg group compared with control group. Conclusion lntrathecal clonidine significantly enhances the antinociceptive effect of intrathecal morphine in a rat model of incisional pain, which might be associated with inhibi-tion of the increased expression of PKA catalytic subunit in spinal cord.     

MR显微成像检测活体阿尔茨海默病转基因小鼠老年斑沉积的效果

目的利用MR显微成像技术研究阿尔茨海默病转基因小鼠老年斑的沉积情况。方法2只17个月龄阿尔茨海默病转基因[V717I]小鼠和2只野生型小鼠，行活体T2WI，然后对照影像定位结果进行组织学切片及免疫组织化学染色。观察T2WI中老年斑的沉积情况以及其与免疫组织化学染色结果的对应关系。结果转基因小鼠T2WI上显示大脑皮层和海马区可见点状低信号，且部分低信号可以和组织学切片所显示的老年斑相对应；野生型小鼠T2WI未见明显的低信号，免疫组织化学染色也未见到染色阳性的斑块。结论MR显微成像技术检测老年斑的沉积是可行的，且可用来特异性地诊断阿尔茨海默病。
