The bioavailability enhancement and insight into the action mechanism of poorly soluble natural compounds from co-crystals preparation: Oridonin as an example.

Background: Natural bioactive molecules are important sources for the development of new drugs. However, most of them were limited in clinical applications due to their low aqueous solubility and bioavailability. Oridonin (ORI) is a powerful anticancer compound with above characteristics.

[Warm-needle moxibustion therapy may reduce aspirin-induced gastric mucosal injury in rats].

Objective: To observe the effect of warm-needle moxibustion on the gastric mucosal injury caused by anti-rheumatic dose of Aspirin.

Methods: Forty SD rats were equally randomized into blank group, model group, warm needling group and Omeprazole (for relieving peptic ulcer) group, with 10 rats in each. The rats were forced to undergo 12 hours' fasting and 4 hours' water-deprivation before the experiments.
