合谷穴与面口部特异性联系的脑网络功能研究

Objective:This study was designed to observe the effect of electroacupuncture at Hégǔ(合谷L14),or Hòuxī(后溪SI3) or Wàiguān(外关TE5) acupoints on the function of the brain regions of a healthy human,and to explore the neural information mechanism of a specific connection between LI4 and the facialoral area from the point of view of the brain function connection network.A further objective was to enrich knowledge of the specific connection between the body surface and the meridian route,and the specificity of acupoint effects.Methods:A total of 30 healthy volunteers were randomly assigned to LI4,SI3,and TE5 groups.The members of each group were stimulated with electroacupuncture,and their heads were scanned using fMRI.DPARSFA 2.4 and REST 1.8 software were used for data preprocessing and statistical analysis.The paired t-test was used within group and the double sample t-test was used for two-group comparisons.Results:In healthy people,left LI4 with electroacupuncture mainly caused a decrease of the functional connection of the right orofacial motor area of the brain,which remained decreased after removing the needle.When LI4 was compared with SI3 and TE5,LI4 caused a more significant decline in the functional connection of the right side of the brain during acupuncture.Conclusions:Acupuncture at LI4 has a significant effect on the function of the face-and mouth-related areas in the brain,and there is a continuous effect.It is suggested that LI4 and the face and mouth have a specific relationship in the brain,which is most obvious during acupuncture.

窝儿七中1个新的木脂素成分

目的研究窝儿七(中华山荷叶Diphylleia sinensis的根及根茎)的化学成分。方法采用硅胶、葡聚糖凝胶Sephadex LH-20、高效液相等色谱技术进行分离纯化,根据理化性质和波谱方法进行结构鉴定。结果从窝儿七根茎95%乙醇提取物中分离得到3个化合物,分别鉴定为山荷叶素-4-O-β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖苷(1)、爵床脂素A(2)、(+)-tanegool-7′-methylether(3)。结论化合物1为新化合物,命名为爵床苷G;化合2和3为首次从山荷叶属植物中分离得到。
