Methods A single muscle spindle was isolated from sartorial mus cle of toad. Using air-gap technique, afferent discharge of the muscle spindle was recorded. Effects of Angelica Sinensis, Salvia Miltiorrhiza, and Safflower o n afferent discharge of the muscle spindle were observed. Results Angelica Sinensis could distinctly increase afferent di scharge frequency of the muscle spindle, and this increase was dose-dependent. But Salvia Miltiorrhiza and Safflower had no this excitatory effect. Conclusion It is known that Angelica Sinensis can invigorate bl ood circulation, and we have found its excitatory effect on muscle spindle which makes it possible to serve people with muscle atrophy if more evidences from cl inical experiments are available.展开更多

Methods: A total of 90 cases of knee osteoarthritis were evenly randomized into Ba-He technique group (observation group) and common technique group (control group), with 45 cases in each group. Zusanli (足三里 ST 36), Heding (鹤顶 EX-LE 2) and Dubi (犊鼻 ST 35 ) were punctured respectively in Ba-He technique and common technique in the two gr oups. The therapeutic effects of the two groups were compared after one course o f treatment (10 sessions) in accordance with Japanese assessment criteria for kn ee-joint functions. Results: After treatment, among the 74 and 7 1 affected knees in the observation and control groups, the therapeutic effect was excellent in 42 (56.8%) and 26 (36.6%) knees, fine in 14 (18.9%) and 20 (28.2%), OK in 10 (13 .5%) and 11 (15.5%), and poor in 8 (10.8%) and 14 (19.7%) respectively. The ther apeutic effect of the observation group was significantly better than that of co ntrol group (P<0.01). Conclusion: The Ba- He technique of acupuncture applied to the above-mentioned three acupoints exerted remarkable therapeutic effect for k n ee osteoarthritis, which is obviously better than that of the common needling te chnique.展开更多

The iterative equation with high- order truncation errors is derived for calculating the specular surface with large aperture based on high-order finite-difference algorithm. To achieve the wavefront estimation and improve convergence speed, the numerical orthogonal transformation method based on Zemike polynomials is implemented to obtain the initial iteration value. The reconstruction results of simulated surface identified the advantages of the proposed method. Furthermore, a freeform in illuminating system has been used to demonstrate the validity of the improved method in practical measurement. The results show that the proposed method has the advantages of making the reconstruction of different shape apertures accurate and rapid. In general, this method performs well in measuring large complex objects with high frequency information in practical measurement.展开更多
