In this study,a functionalized covalent-organic framework(COF)was first synthesized using porphyrin as the fabrication unit and showed an edge-curled,petal-like and well-ordered structure.The synthesized COF was then introduced to prepare porous organic polymer monolithic materials(POPMs).Two com-posite POPM/COF monolithic materials with rod shapes,referred to as sorbent A and sorbent B,were prepared in stainless steel tubes using different monomers.Sorbents A and B exhibited relatively uniform porous structures and enhanced specific surface areas of 153.14 m2/g and 80.01 m2/g,respectively.The prepared composite monoliths were used as in-tube solid-phase extraction(SPE)sorbents combined with HPLC for the on-line extraction and quantitative analytical systems.Indole alkaloids(from Catharanthus roseus G.Don and Uncaria rhynchophylla(Miq.)Miq.Ex Havil.)contained in mouse plasma were extracted and quantitatively analyzed using the online system.The two composite multifunctional monoliths showed excellent clean-up ability for complex biological matrices,as well as superior selec-tivity for target indole alkaloids.Method validation showed that the RSD values of the repeatability(n=6)were≤3.46％,and the accuracy expressed by the spiked recoveries was in the ranges of 99.38％-100.91％and 96.39％-103.50％for vinca alkaloids and Uncaria alkaloids,respectively.Furthermore,sorbents A and B exhibited strong reusability,with RSD values≤5.32％,which were based on the peak area of the corresponding alkaloids with more than 100 injections.These results indicate that the composite POPM/COF rod-shaped monoliths are promising media as SPE sorbents for extracting trace compounds in complex biological samples.

Modern literature on the physical property of the-source point were collected from Chinese National Knowledge Infrastructure(CNKI) and China Biology Medicine(CBM) databases. The physical property,relevant diseases and-source acupoints were analyzed through statistical analysis of literature metrology. It is considered that articles on the electrical resistance of acupoint account for the largest part,which are mainly related to hyperthyreosis and the change of menstrual cycle. The second part is radiation spectrum,which are mostly relevant to the coronary heart disease and then the physiological change of healthy people. As to the diseases,articles of cardiovascular diseases are taken the most proportion,which were treated with the 12-source points,Shenmen(HT 7) and Daling(PC 7). Also,the results present the physical property of-source acupoints in themeridians is more sensitive to diseases and the physical property is specific to diseases. Besides,the-source acupoint can show the pathological changes of its own meridian.
