Objective Panax ginseng is a well-known Chinese traditional medicine functional in “invigorating qi”,and saponins are one of its main effective fractions.Our study investigates the effect of total saponins of panax ginseng(TSPG)on human hematopoiesis at early stage and its possible regulative mechanism to clarify the hematonic mechanism of Panax ginseng. Methods The techniques of culturing hematopoietic progenitor cells in vitro,bioassay of hematopoietic growth factor(HGF),immunocytochemistry and nucleic acid in situ hybridization were used to study the effect of TSPG on IL-3’s expression in hematopoietic stromal cell and its possible mechanism. Results TSPG directly added into culture system in vitro can markedly increase the colony forming yields of CFU-Mix;the different conditioned culture media prepared with TSPG can promote the proliferation and differentiation of CFU-Mix;the protein and mRNA expression of IL-3 in BMSC and cells of EcV304,THP induced by TSPG has been much intensified.Conclusion TSPG may regulate hematopoiesis at early stage by activating IL-3's gene expression in hematopoietic stromal cell,which is the most important element in hematopietic inductive microenvironment(HIM).

6.EEG feature extraction based on quantum particle swarm optimizer and independent component analysis.
Journal of Biomedical Engineering 2014;31(3):502-505
Feature extraction is a very crucial step in P300-based brain-computer interface (BCI) and independent component analysis (ICA) is a suitable P300 feature extraction method. But at present the convergence performance of the general ICA iteration methods are not very satisfactory. In this paper, a method based on quantum particle swarm optimizer (QPSO) algorithm and ICA technique is put forward for P300 extraction. In this method, quantum computing is used to impel ICA iteration to globally converge faster. It achieved the purpose of extracting P300 rapidly and efficiently. The method was tested on two public datasets of BCI Competition II and III, and a simple linear classifier was employed to classify the extracted P300 features. The recognition accuracy reached 94.4% with 15 times averaged. The results showed that the proposed method could extract P300 rapidly and the extraction effect did not reduce. It provides an experimental basis for further study of real-time BCI system.

7.Analysis on professor WANG Juyi's crevice theory from Tao Teh King.
Chinese Acupuncture & Moxibustion 2015;35(10):1069-1072
The crevice theory proposed by professor WANG Juyi is analyzed in this article. In the crevice theory, it is believed that the meridians are located among "skin, pulse, flesh, tendon and bone", and the crevice is the path for the transportation of qi-blood and body fluid in the body, which is the essential condition for vital movement. This is in agreement with the idea of "action through inaction" from Tao Teh King. Based on crevice theory, the abnormalities of meridians can reflex the deficiency and excess of diseases, and regulating meridians is a significant way to treat diseases, and maintaining smooth meridian is important for healthcare.

9.THE LYMPHATIC DRAINAGE OF THE OVARY
Acta Anatomica Sinica 1955;0(03):-
A study of the lymphatic drainage of the ovary in 90 infant cadavers was carried out by injecting into the lymphatics. The specimens were divided into threegroups: in 30 cases the Prussian Blue was injected into the substance of the ovary; in the other 30 cases the infundibulopelvic ligaments were ligated before injection; in the remainder the infundibulopelvic and utero-ovarian ligaments were ligated before injection.The first group: 4-10 lymphatics emerging from the hilus of the ovary ascend along the ovarian blood vessels and terminate in the lumbar nodes. The lymphatics. from the right ovary mostly open into the interaorticocaval nodes and some of them end in the laterocaval nodes, the precaval nodes and the subaortic nodes. The lymphatics from the left ovary mostly end in the lateroaortic nodes and some of them empty into the preaortic nodes.The second group: in 26 sides of the specimens (43%); 1-2 lymphatics emerging from the ovary reach the pelvic wall through the broad ligament and terminate in the interiliac nodes, the internal iliac nodes or the external iliac nodes.The third group: in 19 sides of the specimens (32%), the lymphatics of the ovary also open into the interiliac nodes, the external iliac nodes or the internal iliac nodes.The results demonstrate that the lymph of the ovary drains into the lumbar nodes under normal conditions, and when the primary pathway is ligated the lymph of the ovary may drain into the pelvic nodes.
