Objective To detect the content of polysaccharides in Radix and Rootlet ophiopogonins. Methods Phenylhydrate-sulfuric acid method was used. Results The maximum absorption wavelength was 485 nm. Linear range was 0.101～1.012 mg/L (A=0.826 7C+0.016 3, r=0.999 2). The polysaccharide content in Radix ophiopogonis was 0.301 6 mg/g, and in Rootlet ophiopogonis was 0.359 4 mg/g. The average recovery rate was 100.30% and RSD was 3.14%. Conclusion The polysaccharide content in Rootlet Ophiopogonis was not lower than in Radix Ophiopogonis. It deserves to be more developed and researched.

Objective To observe therapeutic effect in the near future of the operation of vertebrascope in route of retreat to treat lumbar disc protrusion and complications.Method According to symptoms,signs,myelography and CTM results to determine protrusion interspace and side type,applied the operation of vertebrascope in route of retreat to treat lumbar disc protrusion and perform functional exercises.Results 86 patients were followed up,and within these patients,58 appeared excellent (67% ),25 appeared good (29% ), 2 appeared not bad (2% ),and 1 appeared bad(1% ).Conclusion The technology has many advantages, such as little wound, little hemorrhage, little pain and fast restoration,which provide advantageous conditions for early functional exercises after operation.
