Abstract: The present invention relates to a method for preparing a medicine with Chinese yam protein extract for treating erectile dysfunction, which belongs to a technical field of medicine or health products. The present invention proves the improvement effect of the Chinese yam protein extract on the erectile dysfunction in a kidney-yang deficiency experimental model from in vivo and in vitro research systems at multiple levels and all aspects, wherein the Chinese yam protein extract is closely related to improvement of organ functions related to erection control, and the protective effect is different from that of phosphodiesterase type 5 inhibitors. The present invention comprises drugs and health products prepared by using the Chinese yam protein extract as a raw material, which has effects of improving and/or treating the erectile dysfunction at least on mammals.

Abstract: An instrument and method for mechanical properties in situ testing of materials under a high temperature and complex mechanical loads are provided. The instrument includes: a support frame module used to provide a stable support and an effective vibration isolation for each functional module of the instrument; a high-frequency fatigue load applying module used to apply a high-frequency fatigue load on a tested sample; a static-dynamic mechanical load applying module used to apply a combination of static-dynamic tension/compression/bending loads on the tested sample; a high/low temperature applying module used to apply a variable temperature environment from a low temperature to a high temperature on the tested sample; and an in-situ monitoring module that may integrate a surface deformation damage measurement assembly, a three-dimensional strain measurement assembly, a microstructure measurement assembly, and an internal damage detection assembly according to a practical testing requirement.
