[M.O.I.S.T. concept for the local therapy of chronic wounds]

The treatment of patients with chronic wounds is still an interdisciplinary and interprofessional challenge. The basis of successful therapy for these patients is based on causal treatment of the underlying, pathophysiologically relevant diseases. In addition, however, local wound therapy should always be provided to support wound healing and avoid complications. In order to better structure the multitude of wound products, the M.O.I.S.T. concept was developed by a multidisciplinary expert group of WundDACH, the umbrella organization of German-speaking professional societies. M describes, O oxygenation, I infection control, S support of the healing process and T tissue management.The M.O.I.S.T. concept is intended to provide healthcare professionals a guidance for systematic planning and also for education with regard to the local therapy of patients with chronic wounds. The 2022 update of this concept is now presented here for the first time.

Metabolomics Study of Different Germplasm Resources for Three Polygonatum Species Using UPLC-Q-TOF-MS/MS

Rhizomes of the Polygonatum species are well-known in traditional Chinese medicine. The 2020 edition of Chinese Pharmacopoeia includes three different species that possess different pharmacological effects. Due to the lack of standardized discriminant compounds there has often been inadvertently incorrect prescriptions given for these medicines, resulting in serious consequences. Therefore, it is critical to accurately distinguish these herbal Polygonatum species. For this study, UPLC-Q-TOF-MS/MS based metabolomics was employed for the first time to discriminate between three Polygonatum species. Partial least squares discriminant analysis (PLS-DA) models were utilized to select the potential candidate discriminant compounds, after which MS/MS fragmentation patterns were used to identify them. Meanwhile, metabolic correlations were identified using the R language package corrplot, and the distribution of various metabolites was analyzed by box plot and the Z-score graph. As a result, we found that adenosine, sucrose, and pyroglutamic acid were suitable for the identification of different Polygonatum species. In conclusion, this study articulates how various herbal Polygonatum species might be more accurately and efficiently distinguished.
