ABSTRACT
Objective:To establish a method for the determination of asperosaponinⅥin Dieda Cuyu tablets by HPLC. Methods:A Hypersil C18(250 mm ×4.6 mm,5 μm)column was used. The mobile phase was acetonitrile-water(30∶70) with a flow rate of 1.0 ml·min-1 . The detection wavelength was 212 nm, the column temperature was room temperature,and the injection volume was 10μl. Results:AsperosaponinⅥ showed a good linear relationship within the range of 0. 04-0. 32 μg(r=0. 999 6). The average recovery was 97. 84%(RSD=1. 70%, n=6). Conclusion:The method is simple,accurate and reproducible, which can be used in the deter-mination of asperosaponinⅥ in Dieda Cuyu tablets.
ABSTRACT
BACKGROUND:Operation is the main therapy for protrusion of lumbar intervertebral disc.The researches have indicated that non-operation therapy can improve effectively its clinical symptoms.OBJECTIVE:To observe the effect of "three points and five methods"therapy on analgesia of radiculalgia in protrusion of lumbar intervertebral disc and on recovery of motor function in lumbar region and lower limbs.DESIGN:Non-randomized concurrent control study based on the patients.SETTING:Orthopedic department and college of acupuncture and massage of one university-affiliated Hospital.PARTICIPANTS:Totally 210 inpatients of lumbar vertebral disorders were selected from Orthopedic Department of First Affiliated Hospital of Henan College of Traditional Chinese Medicine and Department of Acupuncture and Massage of Third Affiliated Hospital from March 1999 to June 2003,which were randomized into experimental group (n=108) and control group(n=102).METHODS:"Three points and five methods" therapy was adopted in experimental group and the traditional manipulation was for the control.The evaluation on pain and motor function was carried on at minutes 5,10,30,and hours 1,2,...,24 successively for statistical analysis.RESULTS:Total effective rate was 94.44% and the average time of analgesia was(18.40±2.11) hours in the experimental group.Total effective rate was 82.35% and the average time of analgesia was (10.60±2.63) hours in the control group. The analgesia effect and evaluation results on comprehensive function in the experimental group were superior to that in the control group(t=4.86,4.42,P ＜ 0.01).CONCLUSION: "Three points and five methods" therapy releases lumbar pain, improves lumbar symptoms and recovers motor function of lower limbs for the patients with radiculalgia in protrusion of lumbar intervertebral disc.
