[Research progress on the effect mechanism of acupuncture-moxibustion for pressure injuries].

Evidence shows that acupuncture-moxibustion could promote the healing of pressure injuries (PI), but its action mechanism is not fully understood. This review summarizes the basic research literature of acupuncture-moxibustion for PI and identifies that the mechanism of acupuncture-moxibustion for PI is related with regulation of related signaling pathway target proteins, improvement of inflammatory response, modulation of vascular microenvironment, attenuation of oxidative stress damage, and inhibition of cell apoptosis. The review also points out the current limitations and future research directions. It emphasizes the need for further exploration of the upstream regulatory mechanism, specific cellular molecules, and the interactions among these molecules. A multi-level, multi-target, and multi-dimensional approach is required to fully understand the mechanism underlying the promotion of PI healing by acupuncture-moxibustion.

Colocasia kachinensis, a new species of Araceae from Myanmar.

Colocasia kachinensis S.S. Zhou & J.T. Yin, is described and illustrated as a new species of Araceae from Kachin, Mynamar. The morphological characters are compared to those of other Colocasia species. Colocasia kachinensis is closely related to C. menglaensis J.T Yin, H. Li & Z.F. Xu, 2004, but differs from in having an erect stem, no stolons, smaller size, a different pattern of surface bristle distribution and male flowers 1-4-androus with stamens connate in truncate synandrium.
