Traditional Chinese medicines (TCM) is one of the most important sources of new drugs.The rapid development of modern science and technology has brought new opportunities for TCM.Admittedly,new academic theory is getting into a golden period of innovation.Key technologies that enbody TCM features and adapt to modern drug-screening requirements are urgently needed.After five years' endeavor,the authors' group has made great progress in the new theories and methodologies for the discovery of bioactive compounds from TCM.In this review,a total of five key technologies:library-bioactivity-structure integration,biological and chemical fishing technology,ligand-and receptor-based virtual screening,profile-bioactivity relationship and the technology for discovering bioactive equivalent combinatorial components (BECCs),were introduced.In the text,several valuable demonstrations over the TCM-based drug discovery were provided,for uncovering the scientific basis of TCM and accelerating the process of TCM modernization.

To study the clinical application of Jintian'ge capsule in treatment of vertebral compression fracture in senile osteoporosis patients. In the study, 69 senile osteoporotic vertebral compression fracture patients hospitalized in our hospital between January 2012 and June 2014 were selected and randomly divided into the control group and the treatment group. Patients in the control group were treated by percutaneous kyphoplasty (PKP), while those in the treatment group were given Jintian'ge capsule in addition to PKP. Efforts were made to visit the patients before the surgery and in three month after that, observe and compared the vertebral height, Cobb's angle, bone density, visual analogue scale (VAS) and Oswestry disability index between patients in the two groups. According to the findings, compared with before the treatment, patients in the two groups showed significant improvements in the vertebral height, Cobb's angle, bone density, VAS and Oswestry disability index three months after the surgery (P < 0.05); During the visit three months after the treatment, compared with the control group, the treatment group showed notable increases in all parameters (P < 0.05), particularly in the vertebral height, VAS and Oswestry disability index (P < 0.05). Based on the above findings, Jintian'ge capsule is applicable in adjuvant therapy after the osteoporotic vertebral compression facture PKP surgery.

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.

This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.

OBJECTIVETo explore the expression of human leucocyte antigen DR (HLA-DR) gene in peripheral blood mononuclear cells (PBMCs) of systemic lupus erythematosus (SLE) patients of various TCM syndrome types in order to seek an objective index for syndrome differentiation of SLE.
METHODSSLE patients were sorted into various syndrome types by TCM syndrome differentiation, i. e. Pi-Shen yang-deficiency type (A), yin-deficiency with internal heat type (B), qi-yin deficiency type (C) and Gan-Shen yin-deficiency type (D). Their peripheral blood sample was collected for detecting HLA-DR positive lymphocytes and monocytes in PBMC using flow cytometry.
RESULTSComparisons among patients of various syndrome type showed that the proportion of HLA-DR positive monocytes and lymphocytes in PBMC in patients of type A was the lowest (P < 0.01); proportion of HLA-DR positive lymphocytes in patients of type B was significantly higher than in those of type C and D (P < 0.01), and that in type D was higher than in type C (P < 0.05); total proportion of HLA-DR positive cells in patients of type A was the lowest, that in type B was higher than that in type C and D (P < 0.01, P < 0.05), while no significant difference was found between the latter two types (P > 0.05).
CONCLUSIONHLA-DR could be taken as an objective index for reference in syndrome differentiation of SLE.
