目的:观测钩状突尖端(uncina.e process tip,UPT)、椎弓根峡部和颈神经之间的位置关系,为单孔分体脊柱内镜辅助颈椎前路椎间盘切除减压融合术中钩状突精准切除实现颈神经彻底减压提供临床数据参考。方法:选取2016年8月至2021年1月滨州医学院附属医院的26例神经根型颈椎病病人资料,并在Mimics21.0上观测C3~4至C7~T1相关参数:UPT分别至UPT所在矢状面的颈神经前缘前后距离(a.、UPT所在矢状面的颈神经下缘垂直距离(b)、颈神经起点上缘左右距离(c)、颈神经起点上缘垂直距离(d)、颈神经起点下缘垂直距离(e)、椎弓根峡部外侧缘前后距离(f)、椎弓根峡部外侧缘左右距离(g)、颈神经外展角(∠a.、前倾角(∠B)。结果:C_(3~4)至C_(7)~T_(1),同节段不同性别、不同侧别之间差异无统计学意义;同节段b、e之间差异无统计学意义,表明减压UPT所在矢状面的颈神经下缘即可实现颈神经起点下缘减压;随着C_(3~4)至C_(7)~T_(1)节段降低,a.渐减小;b、d、e、g、∠a.∠B逐渐增加;c、f先增加后减小(P<0.05)。结论:以UPT作为重要骨性标志点,明确颈神经减压范围并精准切除钩状突。UPT向前(0.9±0.5)mm至(2.3±1.3)mm至椎弓根峡部外侧缘,向外磨透钩状突,可完成UPT至椎弓根区出口处颈神经腹侧减压;向上(5.5±2.1)mm至(8.0±3.0)mm、向内(1.1±0.5)mm至(1.9±0.9)mm分别磨除部分上位椎体和钩状突后外侧壁增生骨赘,可显露硬脊膜外侧缘和颈神经起点上缘,完成UPT至颈神经起点减压,为手术精准切除钩状突安全减压颈神经提供理论依据。

目的探讨电针对高脂血症大鼠胆汁酸代谢的影响。方法将30只6周龄雄性清洁级Sd大鼠采用数字随机表法分为对照组10只、高脂组20只,分别予普通饲料和高脂饲料喂养,连续10周。测定血清甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LdL-C)值以验证高脂血症建模成功。随后将高脂组采用随机数字表法分为模型组和电针组各10只,电针组每日电针15 min,取单侧足三里、内庭穴,每日1次,对照组和模型组每日束缚固定15 min,连续30 d。电针前后眼眶静脉采血,全自动生化分析仪法检测TG、TC、LdL-C、高密度脂蛋白胆固醇(HdL-C)及血清总胆汁酸(TBa.水平。电针疗程结束后处死大鼠,取肝脏组织样品,运用液相色谱-质谱(LC-MS)联用技术检测各组代谢物含量。采用正交偏最小二乘判别分析(OPLS-da.、变量权重值(VIP)评分对模型组vs对照组,电针组vs模型组进行差异分析;将差异分析得到的代谢物并集,进行层级聚类分析,通过子聚类趋势变化,分析得到模型组vs对照组和模型组vs电针组变化趋势相反的子聚类代谢物,以验证电针治疗效应。创建子聚类代谢物并集,利用KEGG数据库对该并集进行通路富集分析,以确定受影响的代谢通路。结果与模型组比较,电针组干预后血清TG和TBa.均明显降低(P<0.05);与模型组比较,电针组中有61个代谢物明显上调,101个代谢物明显下调,其中包括牛磺酸上调和甘胆酸均下调(P<0.05);筛选出的4个子聚类代谢物创建并集,主要富集在初级胆汁酸生物合成、次级胆汁酸生物合成、胆固醇代谢等代谢通路,其中初级胆汁酸生物合成(P=0.00)和次级胆汁酸生物合成(P=0.00)显著富集。结论高脂饮食诱发的大鼠血脂异常与胆汁酸途径有关,电针足三里、内庭可能经由该途径起降脂作用。

目的探讨植物乳杆菌P9对小鼠免疫功能的调节作用及潜在机制。方法用低、中、高3个剂量(0.5、1.0mg/kg和3.0mg/kg)的植物乳杆菌P9对C57BL/6J小鼠进行灌胃处理,每日记录小鼠一般情况。30d后处死小鼠,计算脏器指数;通过抗体生成细胞实验和血清溶血素实验分析该菌对小鼠体液免疫功能的影响;通过延迟型过敏实验和脾淋巴细胞转化实验分析该菌对小鼠细胞免疫功能的影响;通过对小鼠腹腔巨噬细胞吞噬功能测定、碳廓清实验和细胞活力测定研究该菌对小鼠单核-巨噬细胞功能和自然杀伤(NK)细胞活性的影响。结果对照组与低、中、高剂量植物乳杆菌P9组小鼠的脏器指数差异无统计学意义。但是,植物乳杆菌P9处理后,小鼠血清溶血素生成能力、延迟型过敏、腹腔巨噬细胞的吞噬能力、碳清除能力以及NK细胞活力均显著性提高。结论植物乳杆菌P9可能从体液免疫、细胞免疫、单核-巨噬细胞功能和NK细胞活性等多方面参与调解和改善小鼠的免疫功能。
