Objective To establish a HPLC method for the content determination of Ginsenoside Rg1 in Guyuling Capsule. Methods HPLC was performed on a C18 column ,the mobile phase consisting of acetonitrile-0.5 %H3PO4 (23 ∶77 )and detection wavelength at 205 nm. Results The linearity of Ginsenoside Rg1 was good in the range of 1.05 ?g ～7 ?g,r=0.999 6.The average recovery was 98.80 %,and RSD was 1.57 %.Conclusion The method is simple,feasible,and reproducible ,and can be used for the quality control of Guyuling Capsule.

Objective:To explore the clinical efficacy of a wearable robot for improving the balance and walking function of stroke survivors.Methods:Eighty stroke survivors were randomly divided into an observation group and a control group, each of 40. Both groups were given routine rehabilitation, but the observation group additionally received 20 minutes of training assisted by a wearable robot six days a week for 4 weeks. Before and after the experiment, both groups were evaluated using the Berg Balance Scale (BBS) and functional ambulation categories (FACs). Their movement distance and ellipse area were measured using a Prokin balance instrument, and their step length and pace on the affected side were recorded.Results:Significant improvement in the average BBS and FAC scores, exercise length, ellipse area, and step length and speed on the affected side was observed in both groups. On average, the experimental group′s results were significantly better than those of the control group.Conclusion:Supplementing conventional rehabilitation with wearable robot assistance can significantly improve the balance and walking function of stroke survivors.
