OBJECTIVE: To introduce and analyze the present status of research on decomposed recipes of traditional Chinese medicine (TCM). METHODS: The relevant literature on the study of the decomposed recipes of TCM in the past five years was collected and analyzed. RESULTS AND CONCLUSION: Studies on the decomposed recipes of TCM have been made from the whole body level to the organ, cell and molecular research level. The pharmacological research in vitro is the main way and quantitative changes of the chemical ingredients have been measured before and after composition. It is very important to combine the modern science and technology in exploring the composing mechanisms of TCM remedies.

Objective To establish an HPLC method for the determination of plasma metformin hydrochloride and an HPLC/ESI-MS method for the determination of plasma glibenclamide in human. Methods The metformin plasma samples were added with acetonitrile to denature proteins and the supernatant was injected into the system directly by using EC 250/4.6 NUCLEOSIL 100-5 analytical column (4.6 mm?250 mm, 5 ?m) with a mobile phase of 0.03 mol/L (NH 4) H 2PO 4∶acetonitrile (75∶25, pH 7.0) at the flow rate of 1.0 ml/min and the detection wavelength of 240 nm. Using glipizide as a internal standard, the glibenclamide plasma samples were extracted with ethyl acetate and determined by LC-MS using a chromatographic column ORBAX SB300C 18 (2.1 mm?150 mm, 5 ?m) with a mobile phase of acetonitrile-0.1% ammonium acetate (55∶45, V/V) at the flow of 0.2 ml/min. Results The glibenclamide concentration had a good linear correlation in the range of 2-200 ng/ml (r=0.999 8) while the metformin concentration in the range of 6.25-4 000 ng/ml (r= 0.999 9 ). Both the inter-day and intra-day RSD of metformin and glibenclamide were lower than 5%. Conclusion The assays have been proved to be sensitive, accurate and convenient and can be used in the study of human pharmacokinetics of glibenclamide and metformin hydrochloride.

Objective To realize the optimization of image quality and radiation dose by correcting mammography automatic exposure,according to automatic exposure controlled mode of mammography film-screen system . Methods The film-screen system(28 kV) was applied to perform automatic exposure of plexiglass(40 mm) and get the standard dose of exposure, the exposure mode of CR base on LgM =2.0 was rectified, which was divided into 10 steps. Mammary glands pattern(Fluke NA18-220) were examined with CR( 26,28, and 30 kV ) by the automatic exposure mode corrected. The exposure values(mAs) were recorded. CR image was diagnosed and evaluated in double blind way by 4 radiologists according to American Collage of Radiology(ACR) standard. Results Based on the standard of CR automatic exposure with the dose higher than the traditional exposure of film-screen system, the calibration of mammography automatic exposure was accomplished. The test results of the calibrated mode was better than the scoring system of ACR. Conclusions Comparative study showed improvement in acquiring high-quality image and reduction of radiation dose. The corrected mammography automatic exposure mode might be a better method for clinical use.

Objective To evaluate the preventative effects of rehabilitation training(RT)on deep venous thrombosis(DVT)after arthroplasty.Methods Fifty-six patients with articulatio coxae or knee arthroplasty were randomly divided into a control group and an experiment group(E group).RT,including active movement of the foot and ankle,isometric contraction of the quadriceps fexoris and deep breathing training,was administered to the E group after arthroplasty.Negative cheirapsis was applied in the control group.Peak and average blood flow velocities (PABFVs)in the femoral vein,as well as DVT,were detected and measured using color ultrasound Doppler imaging before and 7 d after arthroplasty.Results PABFVs in the E group were higher than those in the control group (P
