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。     

踝关节X线片分析与临床应用

目的测量正常成人踝关节X线片的有关数据,提高踝关节损伤诊断的准确率,以利于早期治疗、提高疗效。方法40例正常踝关节X线片,测量踝关节间隙内侧宽度、上方胫距关节间隙宽度、距骨外侧与外踝胫侧骨重叠影宽度、侧位片距骨与胫骨之间的宽度、下胫腓联合的宽度、胫骨外侧与腓骨胫侧构成重叠的宽度共六组数据。结果踝穴内侧宽度平均(3.8±0.5)mm,正位距胫关节宽度为(3.0±0.5)mm,距骨外侧与外踝的重叠影为(4.1±2.2)mm,侧位片中距骨与胫骨的间隙为(2.8±0.5)mm,下胫腓联合宽为(3.2±0.7)mm,胫骨外侧与腓骨胫侧重叠影宽平均为(7.7±1.9)mm。结论综合分析各组正常值,结合其它骨折改变,超过正常值范围是距骨脱位移位下胫腓联合分离的依据。多组数据改变可提高早期诊断准确率。

重症急性胰腺炎早期治疗的探讨及分析

目的 探讨重症急性胰腺炎（SAP）早期治疗体会及外科手术治疗时机和手术方式的选择。方法 对比分析1989—1995年以早期手术为主的36例SAP（A组）与1996—2003年7年中非手术治疗为主的44例SAP（B组）的治愈率和死亡率。结果 B组的死亡率明显低于A组，A组的治愈率低于B组。结论 SAP早期的急性炎症反应期，手术只能加重对机体的打击，加重SAP全身炎症反应，增加手术死亡率。故SAP早期治疗应以非手术疗法为主。当内科治疗无效，手术治疗是唯一的选择，而手术时机的掌握和手术方式的选择更为重要，直接影响手术结果。
