Acupuncture and Global Health: Providing Medical Acupuncture Education and Service in Georgetown, Guyana.

Objective: Guyana is located on the north coast of the South American continent and is a middle-income developing country in the Caribbean. There is little educational opportunity for individuals interested in medical acupuncture. The aim of this project was to develop an introductory medical acupuncture curriculum for perioperative use. Materials and Methods: Through a carefully coordinated teaching-and-care plan, with support from physicians and various medical organizations, an educational opportunity in medical acupuncture was established at the Georgetown Public Hospital Corporation, a medical university teaching hospital in Georgetown, Guyana. The project involved development of a medical acupuncture curriculum, as well as teaching and patient care. Anesthesia staff members, resident trainees, and perioperative and pain-clinic patients participated. Results: Medical acupuncture-trained physicians were able to provide medical acupuncture education and services in a third-world country because of this project. Conclusion: This project is an ideal example of utilizing medical acupuncture for promoting global heath.

Analyses of the pericyte transcriptome in ischemic skeletal muscles.

BACKGROUND: Peripheral arterial disease (PAD) affects millions of people and compromises quality of life. Critical limb ischemia (CLI), which is the most advanced stage of PAD, can cause nonhealing ulcers and strong chronic pain, and it shortens the patients' life expectancy. Cell-based angiogenic therapies are becoming a real therapeutic approach to treat CLI. Pericytes are cells that surround vascular endothelial cells to reinforce vessel integrity and regulate local blood pressure and metabolism. In the past decade, researchers also found that pericytes may function as stem or progenitor cells in the body, showing the potential to differentiate into several cell types. We investigated the gene expression profiles of pericytes during the early stages of limb ischemia, as well as the alterations in pericyte subpopulations to better understand the behavior of pericytes under ischemic conditions. METHODS: In this study, we used a hindlimb ischemia model to mimic CLI in C57/BL6 mice and explore the role of pericytes in regeneration. To this end, muscle pericytes were isolated at different time points after the induction of ischemia. The phenotypes and transcriptomic profiles of the pericytes isolated at these discrete time points were assessed using flow cytometry and RNA sequencing. RESULTS: Ischemia triggered proliferation and migration and upregulated the expression of myogenesis-related transcripts in pericytes. Furthermore, the transcriptomic analysis also revealed that pericytes induce or upregulate the expression of a number of cytokines with effects on endothelial cells, leukocyte chemoattraction, or the activation of inflammatory cells. CONCLUSIONS: Our findings provide a database that will improve our understanding of skeletal muscle pericyte biology under ischemic conditions, which may be useful for the development of novel pericyte-based cell and gene therapies.
