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.

Objective To establish a new method for measuring the 3-D kinematics of hindfoot joints in vivo by using reverse engineering software together with the theory of rigid body kinematics.Methods CT images were gathered from 9 feet of 5 healthy volunteers in both the initial position (neutral position) and the terminal position (extremely inversion-adduction-dorsiflexion position).The 3-D digital modules of hindfoot joints in the initial position and terminal position were established with MIMICS 10.01 software.The data of reconstructed digital modules was inputted into the GEOMAGIC 10.0 software in STL format for twice registration,and then their relatively displacement and changes of angle in 3-D space between the two positions were calculated Results The rotation range of the tibiotalar joint was 3.89° ±2.77° in eversion,5.29°±4.47° in abduction,10.77°+5.70° in dorsiflexion,and the relative displacement was 0.78±0.59 mm towards lateral ankle,0.18±0.75 mm towards the hindfoot,(0.65±0.71) mm towards the proximal limbs;the range of subtalar joint was 16.46°±2.94° in inversion,12.77°±1.81° in adduction,6.33°±4.32° in plantarflexion,and the relative displacement was 5.50±1.45 mm towards medial ankle,1.96±1.77 mm towards forefoot,0.43±1.18 mm towards distal limbs; the range of talonavicular joint was 38.82°±5.98° in inversion,19.71°±6.33° in adduction,5.09°±6.89° in plantarflexion,and the relative displacement was (9.77±1.73) mm towards medial ankle,3.13±1.29 mm towards hindfoot,4.64±1.42 mm towards proximal limbs.Conclusion This method measuring 3-D kinematics of hindfoot joints in vivo is non-invasive and easy to operate.

The means of OD value measurement and plate counting were used to choose the bacterial growth stimulants. Among the 120 substances sorted to 13 kinds (the trace elements, REE, carbohydrate, amino acids and amino acids derivatives, vitamins, nucleosides, plant hormones, animal hormones, plant and animal extracts, Echlonia Kurome Okum water extract and yeast extract), Echlonia Kurome Okum water extract and yeast extract were found to stimulate the growth of Escherichia coli significantly.

· AIM:To compare the effect of fixation and select the optimal fixation solution and condition for PAS staining of guinea pig eyes among three different fixation solution:4％ paraformaldehyde solution,4％ glutaraldehyde solution and Davidson solution.· METHODS:Totally 30 healthy guinea pigs were divided into 6 groups:Group Ⅰ-Ⅱ were fixed in 4％ paraformaldehyde solution and 4％ glutaraldehyde solution for 24h,respectively;Group Ⅲ-Ⅴ were fixed in Davidson solution for 3,6 and 24h,respectively;and Group Ⅵ were fixed in Davidson solution for 3h and then transferred into 10％ neutral formaldehyde solution for 48h.All groups were sectioned by routine section method and undergone PAS staining,and then observed by light microscope.· RESULTS:It was found that the group which was fixed by Davidson solution for 3h,remained the most complete structure for PAS staining (Group Ⅲ).While the effect of fixation for the group which was transferred into 10％ neutral formaldehyde solution for preserving for 48h after fixing in Davidson solution for 3h was also acceptable for PAS staining (Group Ⅵ).The retinal cells remained clear and in order for both groups which was mentioned above.· CONCLUSION:The best fixation condition for PAS staining for eyes of guinea pigs is fixation in Davidson solution for 3h among these fixation conditions,while it is also suitable to transfer the eyes into neutral formaldehyde solution after fixing in Davidson solution for 3h for preserving for long periods,which is not severely reduced the effect of fixation for PAS staining.
