Objective: To investigate the clinical efficacy of acupuncture in treating cerebral infarction by its intervention in the acute stage. Methods: A treatment group of 49 cases was treated with acupuncture by its intervention in the acute stage plus rehabilitation in the convalescent stage, and a control group of 28 cases, with acupuncture applied only to the convalescent stage. Results: The total effective rate was 95.9% in the treatment group and 78.6% in the control group. The curative effect was significantly higher in the treatment group than in the control group. Conclusion:The treatment of cerebral infarction by early acupuncture intervention is safe, reliable and exactly effective. It is worthy to be popularized and applied.

OBJECTIVETo study the scavenging DPPH free radicals activity of flavone C-glycosides from different parts of Dendrobium officinale.

METHODThe types and contents of flavonoids from different parts of D. officinale were analyzed by TLC and HPLC. The antioxidant effect was tested by scavenging DPPH free radicals activity.

RESULTThe stems, leaves and flowers contained the same type of flavone C-A glycosides and 8 common peaks were identified. The content of flavone C-A glycosides was significantly different. The content of flavone C-glycosides in leaves and flowers was higher than that in stems. The flavonoid in roots was less. Stems contained naringenin, which was not identified in root, leave and flower. Both stems and leaves had antioxidant capacity of eliminating DPPH free radicals, of which scavenging DPPH free radicals activity of leaves was better than stems.

CONCLUSIONConsidering the content of flavonoid and antioxidant activity leave and flower of D. officinale may substitute stems. The study provides a preliminary basis for the development and utilization of leave and flower of D. officinale.
