Jin's three-needle technique is named after Professor JIN Rui. The connotation of Jin's three-needle technique is summarized by his followers through long-term teaching and clinical practice. His principle and method of point combination are based on syndrome differentiation of acupuncture. And his unique needling technique and treating principle of mental tranquilization also play an important role in his clinical practice.

Objective To investigate the function of soluble stem cell factor receptor(s-kit)and stem cell factor(SCF) in chronic aplastic anemia(CAA).Methods ELISA assay was employed to determine the levels of s-kit and SCF in peripheral blood of CAA patients and umbilical cord blood.Results The levels of s-kit and SCF in peripheral blood of CAA patients are lower than those of normal group and umbilical cord blood group.Conclusions The decreased levels of s-kit and SCF show that s-kit and SCF may play a role in CAA mechanism.The raised levels of s-kit and SCF show that s-kit and SCF may be applied in the field of cord blood transplantation.

Aim To develop the in vitro and in vivo models induced by shrimp tropomyosin( ST) and mono-clonal tropomyosin-specific murine IgE antibody ( anti-ST-IgE mAb) . Methods ST was purified from Metap-enaeusensis by an isoelectric precipitation method. The anti-ST-IgE mAb was obtained from hybridomas. After RBL-2 H3 cells were sensitized with anti-ST-IgE mAb and challenged with ST,β-hexosaminidase release was determined. Passive systemic anaphylaxis ( PSA ) was induced in mice and the rectal temperature was recor-ded after ST challenge within 30 min by a thermal probe. Results A significant increase ofβ-hexosamin-idase was observed in sensitized cells after ST chal-lenge. The average temperature drop after ST challenge was 1. 44℃ in PSA mice within 30 min. Conclusion The in vitro and in vivo models induced by ST and anti-ST-IgE mAb are established as an improvement of pres-ent models of type Ⅰ allergy.

Objective:To develop murine models of Th2 response induced by shrimp tropomyosin (ST). Methods:Mice were sensitized with ST for 6 weeks. The serum antigen-special IgE (sIgE),total IgE and sIgG level,Th1/Th2 cytokines production were measured by ELISA. The basophil activation in mice was measured by flow cytometry. Results:The intraperitoneal sensitization with ST for 6 weeks induced significant increase of serum sIgE,total IgE and sIgG (sIgG1,sIgG2a and sIgG2b) level in mice. Th2 cell response was induced and cytokines (IL-4,IL-5,IL-10 and IL-13) production increased in splenocytes stimulated by ST,while Th1 cytokine (IFN-γ) production decreased. As the markers of basophil activation,CD200R and CD41 expression also increased in response to ST. Conclusion:The Th2 response is dominant in ST-induced anaphylaxis in mice.

A phytochemical investigation on the roots and stems of Litsea cubeba led to the isolation of seven isoquinolone alkaloids. By spectroscopic analysis and comparison of their 1H and 13C-NMR data with those in literatures, these alkaloids were identified as (+)-norboldine (1), (+)-boldine (2), (+)-reticuline (3), (+)-laurotetanine (4), (+)-isoboldine (5), (+)-N-methyl-laurotetanine (6), and berberine (7), respectively. Among them, 7 was isolated from the genus for the first time. The evaluation of these compounds showed weak anti-inflammatory activity against NO production in RAW 267.4 and BV-2 cells.

The peeled stem of Syringa pinnatifolia is a Mongolia folk medicine, mainly distributed in Helan mountain, inner Mongolia and Ningxia provinces of China. It has been used for the treatment of cardiopalmus, angina pectoris, and cardiopulmonary diseases for a long history. Contemporary research revealed the presence of major lignans, sesquitepenes, and essential oils, and showed myocardial ischemia related diseases. This review summarizes the plant origins, taxonomic disputes, phytochemical and pharmacological research progress, hopefully to provide reference for full medicinal utilization, clarification of biological effective substance, and drug development.

OBJECTIVETo explore the antitumoral effect of indirubin on androgen-independent prostate cancer PC-3 cells and its possible mechanisms.

METHODSWe measured the inhibitory effect of indirubin on the proliferation of prostate cancer PC-3 cells using MTT assay, detected their cell cycles by flow cytometry, and determined the expressions of the cell cycle regulatory protein cyclin D1 and its related downstream gene c-myc by Western blot.

RESULTSThe viability of the PC-3 cells was significantly decreased by indirubin in a concentration-dependent manner, reduced to 52. 2% and 13. 6% at 5 and 10 µmol/L, respectively. The cell cycle of the PC-3 cells was markedly inhibited by indirubin at 5 µmol/L, with the cells remarkably increased in the G0 and G1 phases and decreased in the S and G2/M phases. Meanwhile, indirubin also inhibited the expressions of cyclin D1 and c-myc in the Wnt signaling pathway.

CONCLUSIONIndirubin can suppress the proliferation of androgen-independent prostate cancer PC-3 cells, which may be associated with its inhibitory effect on the cell cycle and Wnt signaling pathway.

This study reported the obtainment of the full-length cDNA of Salvia miltiorrhiza hairy roots (Abbr: SmHDR, GenBank number: JX233817), via extracting Salvia miltiorrhiza hairy roots total RNA, designing specific primers according to the transcriptome data and using the RACE strategy, and then analyzed it with bioinformatics approaches. On this basis, using the real-time PCR to detect SmHDR gene expression after Ag+ induction, and testing tanshinones contents of corresponding samples by UPLC. SmHDR has 1 647 nucleotides, and an open reading frame (ORF) encoding a protein of 463 amino acid residues. The deduced protein has isoelectric point (pI) of 5.72 and a calculated molecular weight about 51.88 kD. In the secondary structure, the percentage of alpha helix, beta turn and random coil were 35.64%, 20.30% and 44.06%, respectively. Sequence alignment and phylogenetic analysis demonstrated that SmHDR had relative close relationship to the HDR of Picrorhiza kurrooa, similar to HDR from other species of plants. Real time PCR results indicated that elicitor of Ag+ stimulated the increase of mRNA expression of SmHDR. At the same time, results of ultra performance liquid chromatography (UPLC), used to examine the accumulation of diterpenoid tanshinones in hairy roots, showed that the contents of diterpenoid tanshinones in hairy roots of Salvia miltiorrhiza were increased dramatically at 12 h after treated with Ag+, and then decreased significantly. This result showed a positive correlation between the levels of mRNA expression and tanshinones accumulation in Salvia miltiorrhiza stimulated by Ag+. The content of tanshinones was gradually raised, and it had an obvious increase at 120 h. The bioinformatics analysis and gene expression indicated that SmHDR might be involved in tanshinones biosynthesis, which laid the foundation for further study of secondary metabolic regulation mechanism of tanshinones.

The influence on 10 kinds of ginsensides of different processed methods of Panacis Quinquefolii Radix was discussed. White Panacis Quinquefolii Radix (sliced and dried at -80 °C), red Panacis Quinquefolii Radix( steamed, sliced and dried at -80 °C) and commercial Radix Panacis Quinquefolii (dried by electric blast air) processed by different methods. HPLC-PDA-ESI- MS method was established before by our team. Ten kinds of ginsenosides of them were determined. The content of total ginsenosides were as follow: commercial Panacis Quinquefolii Radix > white Panacis Quinquefolii Radix > red Panacis Quinquefolii Radix. Compared with white Panacis Quinquefolii Radix, the content of Re, Rc, Rb3 and Rb2 of Red Radix Panacis Quinquefolii decreased but increased that of Rg,, Rb1. Both Rg2 and Rg, were not found in white Panacis Quinquefolii Radix and commercial Panacis Quinquefolii Radix by PDA detector, and low response in ESI-MS, while red Panacis Quinquefolii Radix was to the high content that of 0. 027% and 0.040 1%. The constituent of RA0 of red Panacis Quinquefolii Radix was higher than the other two. After Panacis Quinquefolii Radix processed, the kind and content of ginsensides were significantly changed. The constituent of some kinds of ginsensides was increased and some decreased. Rf was not found in all Panacis Quinquefolii Radix samples which were consistent with the former documents.
