1.Research advances in regulation of hypoxia-inducible factor-1 by camptothecin compounds
Journal of International Oncology 2008;35(10):729-731
Hypoxia- inducible factor-1 ( HIF-1) promotes tumor deterioration, invasion and metasta-sis. Treatment targeting the HIF-1 signal pathway is becoming a hot research. In addition to uniquely selective inhibition of topoisomerase Ⅰ(Topo Ⅰ) ,the recent studies show that camptothecin compounds can regulate the activity of HIF-1 through decreasing HIF-1 protein translation and have been classified as a non-selective chemical inhibitor of HIF-1.
2.Antitumor mechanism of FTY720
Journal of International Oncology 2010;37(7):520-523
Sphingosine analogue FTY720 exerts good immune suppressive effect by inducing lymphocytes apoptosis and homing, which can be used for organ transplant rejection as well as anti-autoimmune disease treatment. Recent studies have found that FTY720 plays anti-tumor potential by inducing growth arrest and apoptosis as well as inhibiting tumor metastasis.

4.Determination of notoginsenoside R_1,ginsenoside Rg_1,Rb_1 in Jingkang Capsules by HPLC
Chinese Traditional Patent Medicine 1992;0(02):-
AIM:To establish a method for determining notoginsenoside R_1,ginsenoside Rg_1 and ginsenoside Rb_1 in Jingkang Capsules(Radix Rehmanniae praeparata,Radix Polygoni multiflori,Radix et Rhizoma Notoginseng,etc.). METHODS: A Diamonsil C_(18) column(250 mm?4.6 mm,5 ?m) with acetonitrile-water as the mobile phase was used for gradient elution,the flow rate was 1.0 mL/min and the UV detection wavelength was at 203 mn. RESULTS: There was a good linear relationship at a range of 0.327-2.180 ?g for notoginsenoside R_1(r=(0.999 4))(the average recovery was 98.23% with RSD of 1.53%(n=6)),0.909-6.060 ?g for ginsenoside Rg_1(r=1.0)(the average recovery was 99.04% with RSD of 1.00%(n=6)),0.672-4.480 ?g for ginsenoside Rb_1(r=0.999 8)(the average recovery was 98.17% with RSD of 1.31%(n=6)).CONCLUSION: The method is simple,quick and accurate.It can be used for the quality control of Jingkang Capsules.

6.RP-HPLC Determination of Matrine in Fuji Lotion
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(02):-
Objective To establish a method for determination of matrine in Fuji Lotion. Methods An Inertsil NH2 column (250 mm?4.6 mm, 5 ?m) was used with acetonitrile-ethanol absolute-3% phosphoric acid (83∶8.5∶8.5) as mobile phase, the flow rate was 1.0 mL/min, and the UV detection wavelength was set at 220 nm. Results The calibration curve of matrine was linear in range of 0.039~1.560 ?g, r=0.999 7. The average recovery was 97.8% with RSD of 1.1% (n=6). Conclusion The method is simple, quick and accurate. It can be used for the quality control of Fuji Lotion.
7.Biocompatibilities of bone marrow stromal cells and chitosan/tricalcium phosphate
Journal of Jilin University(Medicine Edition) 2006;0(04):-
Objective To study the effect of chitosan/tricalcium phosphate(CTCP)on the attachment and proliferation of bone marrow stromal cells(BMSCs)cultivated in vitro and explore their biocompatibilities.Methods The CTCP was prepared by freeze-drying.BMSCs were cultivated in vitro,collected and seeded onto the surface of CTCP.Cell attachment and proliferation were obesrved using inverted light microscope and scanning electron microscopy(SEM).The cell proliferation was tracked by MTT method 2,4,6,8 d after seeding.Results BMSCs were fibroblast-like 2 d after seeding.The mean number of cells was(360?20) and(76?18),respectively,in the experimental and control group per 100 eyesight field,the difference was significant(P

Chinese Medical Equipment Journal 2004;0(07):-
This paper not only analyzes the technology characteristic and market prospects of medical motor vehicle equipment in China,summarizes the current status of the development and standardization of medical vehicles inside and outside army,but also demonstrates the standardization system of medical motor vehicle technology in China,puts forward the solving methods and measures for the lack of medical motor vehicle equipment standards.
9.Detection and risk analysis of hereditary deafness
International Journal of Biomedical Engineering 2006;0(06):-
Hereditary hearing impairment is caused by genetic defects and is a common clinical disease. Since the lack of efficient treatment method, genetic counseling is more important in this field. It provides information about inherited disorders and focuses on assessment and interpretation of the risk for occurrence of genetic conditions in the family. Presented in this paper are classification of hereditary hearing impairment and methods to perform probability analysis using features of pathogenic genes and information of pedigree.
10.Enhancing the safety of corneal tissue after the excimer laser refractive ablation
Ophthalmology in China 1993;0(03):-
The corneal refractive surgery is invented and improved constantly from 1970's till now,and the excimer laser corneal refractive surgery is the important method for correcting myopia.The corneal safety of post-operation long time is the key point and always is worried by surgeon due to the surgical procedure directly on the normal corneal tissue by different types of flap and ablation. From the corneal safety of view,the advantages and disadvantages of different corneal refractive surgeries were compared and the indications for different methods were mentioned in order to provide rational clinical data.
