Measuring conduction velocity distributions in peripheral nerves using neurophysiological techniques

ObjectiveTo determine how long it takes for neural impulses to travel along peripheral nerve fibers in living humans.MethodsA collision test was performed to measure the conduction velocity distribution of the ulnar nerve. Two stimuli at the distal and proximal sites were used to produce the collision. Compound muscle or nerve action potentials were recorded to perform the measurements on the motor or mixed nerve, respectively. Interstimulus interval was set at 1–5 ms. A quadri-pulse technique was used to measure the refractory period and calibrate the conduction time.ResultsCompound muscle action potential produced by the proximal stimulation started to emerge at the interstimulus interval of about 1.5 ms and increased with the increment in interstimulus interval. Two groups of motor nerve fibers with different conduction velocities were identified. The mixed nerve showed a wider conduction velocity distribution with identification of more subgroups of nerve fibers than the motor nerve.ConclusionsThe conduction velocity distributions in high resolution on a peripheral motor and mixed nerve are different and this can be measured with the collision test.SignificanceWe provided ground truth data to verify the neuroimaging pipelines for the measurements of latency connectome in the peripheral nervous system.     

基于“脾胰同源”应用养阴益气活血法减少血糖波动干预糖尿病大血管病变的研究

目的探讨基于"脾胰同源"应用养阴益气活血法观察参芪复方对糖尿病血糖波动的影响。方法建立由高脂饲料喂养的糖尿病大血管并发症大鼠模型,实验分为空白组,模型组,参芪复方组,西药西格列汀组,各组灌胃8周。实验期间观察动物一般状况,在灌胃的第4周每周1次测定1日内5个时间点的血糖情况,并计算MBG、SDBG、LABG值。灌胃8周后处死GK大鼠,检测各组血脂水平、CRP、血清胰岛素、血清胰高血糖素、血清GLP-1,对腹主动脉及胰腺组织进行HE染色后进行病理形态学观察。结果参芪组一般状况优于模型组,血糖波动方面,每日平均血糖标准差(SDBG)和最大血糖波动幅度(LAGE)值优于模型组。甘油三酯(TG)、胆固醇(TC)以及C反应蛋白(CRP)较模型组降低,但与西药组无统计学意义。胰岛素(INS)与胰高血糖素(GC)与模型组相比,无统计学意义;而GLP-1较模型组有显著的差异(P<0.01)。病理方面,参芪组腹主动脉和胰腺切片优于模型组和西药组。结论应用参芪复方可以改善糖尿病大血管病变GK大鼠的一般状态,提高GLP-1的浓度,控制血糖的波动幅度;且可以改善脂代谢紊乱,降低CRP,减轻模型GK大鼠血管内皮损伤,延缓糖尿病大血管病变的进展。

目的观察红藤虎杖复方免煎剂对急性痛风性关节炎模型小鼠细胞因子的表达,并探讨其可能作用机制。方法将KM雌雄性小鼠各36只,称重后随机分成空白组、模型组、阳性组和中药高、中、低剂量组,正常饲养1周后,连续灌胃5 d,第6天在小鼠踝关节注射尿酸钠诱导急性痛风性关节炎模型。测定足趾容积、HE染色观察滑膜组织病理形态,以及ELISA法检测IL-1β、TGF-β1、TNF-α、IL-1、IL-8、IL-1Ra在踝关节滑膜组织中的表达。结果与空白组比较,模型组右足趾容积明显增加;IL-1、IL-1β、IL-8、TNF-α水平均显著增高(P<0.01);IL-1Ra、TGF-β1较空白组增高(P<0.05)。与模型组比较,阳性组、中药高、中剂量组右足趾容积明显降低;IL-1、IL-1β、IL-8、TNF-α水平均显著性降低(P<0.01);TGF-β1、IL-1Ra水平均显著性增高(P<0.01)。与阳性组比较,中药高剂量组IL-1显著降低((P<0.01);中药高、中剂量组IL-1β、TNF-α较阳性组降低(P<0.05);中药高、中剂量组IL-8、IL-1Ra、TGF-β1与阳性组比较无显著性差异(P>0.05);HE染色观察显示高剂量组滑膜组织炎症浸润改善明显。结论红藤虎杖复方免煎剂能治疗小鼠急性痛风性关节炎,其作用机制可能与MSU诱导的促炎细胞因子及抗炎细胞因子的产生有关,且高剂量效佳。     

Pharmacological evaluation and mechanistic study of compound Xishu Granule in hepatocellular carcinoma

ObjectiveIn this study, we used HepG2 human hepatocellular carcinoma cells to study the effects of Compound Xishu Granule (CXG) on cell proliferation, apoptosis, and the cell cycle in vitro. We also used a xenograft tumor model to study the anti-tumor effects of CXG and related mechanisms in vivo.MethodsThe effect of CXG on cell viability was measured using Cell Counting Kit-8 and a colony formation assay. The effect of CXG on apoptosis and the cell cycle was analyzed using flow cytometry. The in vivo anti-tumor effect of CXG was assessed by measuring the volume change in xenograft tumors after drug administration. The CXG anti-tumor mechanism was studied using western blotting assay to detect cell cycle and apoptotic associated proteins.ResultsCXG suppressed HepG2 cell proliferation in a time- and dose-dependent manner in vitro. Colony formation experiments showed that CXG administration for 24 h significantly reduced HepG2 cell formations (P < .01). Flow cytometric analysis showed that CXG treatment for 48 h promoted apoptosis and blocked HepG2 cells in the G2/M phase. Western blotting results showed that Bax was significantly up-regulated and Bcl-2 was down-regulated in graft tumor tissues and HepG2 cells after CXG administration, which increased the Bax/Bcl-2 ratio. PLK1, CDC25C, CDK1, and Cyclin B1 expression were up-regulated. CXG had a good inhibitory effect on graft tumor growth in vivo.ConclusionCXG has good anti-tumor effects in vitro and in vivo. In vitro, CXG promoted HepG2 cell apoptosis and induced G2/M phase arrest. In vivo, CXG significantly inhibited graft tumor growth. The CXG mechanism in treating hepatocellular carcinoma may be that CXG can induce abnormal apoptotic and cell cycle associated protein expression, leading to mitotic catastrophe and apoptosis.
