近红外激光照射人体合谷穴与非穴位区的温度和背向散射光强度的时间相关性比较研究

研究了人体合谷穴以及周边的非穴位组织受不同功率的半导体激光(808 nm功率分别为15,25,35 mW)照射前后,穴位和非穴位组织的温度和在不同深度处的背向散射光强度的时间相关性及其差异。实验采用红外热成像和光相干层析成像技术获取人体穴位区和非穴位区的温度及其背向散射光强度。结果表明,在808 nm激光照射前,穴位区和非穴位区的温度和背向散射光强是基本相同,照射后,穴位区的温度和背向散射光强明显地高于非穴位区的温度。在照射后的0～40 min内,穴位区和非穴位区的温度和背向散射光强都随着时间的增加而波动地缓慢下降。实验结果表明,合谷穴的穴位区与非穴位区对近红外激光照射前后的温度与时间的相关性和不同深度处的背向散射光强度的时间相关性有明显的差异,且穴位区对半导体激光器的照射反应比非穴位区更敏感。     

近红外激光照射人体劳宫穴和非穴位区的反射光谱特性的比较研究

研究了人体劳宫穴及其周边的非穴位组织受不同功率的半导体激光(波长为808 nm功率分别为20,50,100 mW)照射前后在400～1 000 nm光谱范围的反射光谱特征及其差异.实验采用带积分球附件的AvaSpec-2048光纤光谱仪测量系统获取劳宫穴和非穴位组织的反射光谱.结果表明,在半导体激光照射前,劳宫穴与非穴位的反射光谱的光谱轮廓相似,波谷均出现在423,544,577,980 nm处,劳宫穴和非穴位在对应波谷的反射率值分别为17.1%,26.1%,25.9%,35.0%和17.1%,27.6%,28.1%,36.5%.在475～1 000 nm,合谷穴的反射率比非穴位小.分别经过20,50和100 mW不同功率的半导体激光照射后,劳宫穴反射率较照射前明显下降,并且随着照射功率增大,反射率减小的幅度越大.而非穴位组织经过不同功率的半导体激光照射后反射率较照射前稍有下降,但远不及劳宫穴下降明显.由此可见劳宫穴与非穴位的反射光谱存在差异,并且劳宫穴对半导体激光照射的刺激比非穴位更敏感.     

Long-duration transcutaneous electric acupoint stimulation alters small-world brain functional networks

Acupuncture, which is recognized as an alternative and complementary treatment in Western medicine, has long shown efficiencies in chronic pain relief, drug addiction treatment, stroke rehabilitation and other clinical practices. The neural mechanism underlying acupuncture, however, is still unclear. Many studies have focused on the sustained effects of acupuncture on healthy subjects, yet there are very few on the topological organization of functional networks in the whole brain in response to long-duration acupuncture (longer than 20 min). This paper presents a novel study on the effects of long-duration transcutaneous electric acupoint stimulation (TEAS) on the small-world properties of brain functional networks. Functional magnetic resonance imaging was used to construct brain functional networks of 18 healthy subjects (9 males and 9 females) during the resting state. All subjects received both TEAS and minimal TEAS (MTEAS) and were scanned before and after each stimulation. An altered functional network was found with lower local efficiency and no significant change in global efficiency for healthy subjects after TEAS, while no significant difference was observed after MTEAS. The experiments also showed that the nodal efficiencies in several paralimbic/limbic regions were altered by TEAS, and those in middle frontal gyrus and other regions by MTEAS. To remove the psychological effects and the baseline, we compared the difference between diffTEAS (difference between after and before TEAS) and diffMTEAS (difference between after and before MTEAS). The results showed that the local efficiency was decreased and that the nodal efficiencies in frontal gyrus, orbitofrontal cortex, anterior cingulate gyrus and hippocampus gyrus were changed. Based on those observations, we conclude that long-duration TEAS may modulate the short-range connections of brain functional networks and also the limbic system.

以功能性核磁共振造影初探10Hz调制激光针灸刺激所引发人类大脑皮质的活化现象(英文)

使用10 Hz调制的低功率激光针灸刺激探究大脑皮质反应.以功能性核磁共振造影技术探讨当激光针灸刺激左脚涌泉穴(K1)时,大脑可能产生的反应机制.研究发现调制激光针灸所引发显著的大脑活化反应,包括右额叶中央前回、右额叶上回、左额叶中央前回、左顶叶中央后回、左侧下部顶叶、左小脑舌前叶、左海马旁回和左小脑山顶等区域.安慰剂组实验并没有发现在脑部有任何活化反应,大多数反应区域所涉及功能与记忆、注意力及自我意识等有关联.结果显示出调制激光针灸的大脑血液动力学反应,并隐含此反应机制不只是依据传入感觉信息处理,而且还有着随外部刺激的变化而有所改变的血液动力学性质.

Pharmacokinetics and tissue distribution of five bioactive components in the Corydalis yanhusuo total alkaloids transdermal patch following Shenque acupoint application in rats assessed by ultra-performance liquid chromatography–tandem mass spectrometry

The purpose of this study was to evaluate the pharmacokinetics and tissue distribution of the Corydalis yanhusuo total alkaloids transdermal patch (CTTP) following Shenque acupoint application in rats. The concentrations of corydaline, tetrahydropalmatine, tetrahydrocolumbamine, protopine, and dehydrocorydaline in rat plasma and various tissues were simultaneously detected by ultra-performance liquid chromatography–tandem mass spectrometry after Shenque acupoint administration of CTTP. Plasma, heart, liver, spleen, lung, and kidney tissue samples were collected at specific times and separated by gradient elution on an ACQUITY UPLC HSS T3 column (1.8 μm, 100 mm × 2.1 mm) with a mobile phase of 0.01% formic acid aqueous solution and acetonitrile–0.01% formic acid. The methodological results showed that the selectivity, linear range, accuracy, precision, stability, matrix effect, and extraction recovery of the established method met the requirements of biological sample analysis. The results indicated that CTTP following Shenque acupoint administration rapidly delivered adequate drug into rat blood and maintained an effective plasma level for a significantly longer time than non-acupoint administration. Furthermore, CTTP effectively reached the liver through Shenque acupoint administration and showed tissue selectivity. The data obtained could provide a prospect for the treatment of chronic pain with CTTP following Shenque acupoint application.
