ABSTRACT
In recent years, a large number of studies have shown that non-coding RNAs play an important role in wound healing process. Among them, studies on the mechanism of circular RNA (circRNA) have shown that circRNA is closely related to the proliferation of cells related to wound healing, such as endothelial progenitor cells and keratinocytes, and circRNA is also involved in the chronic wound healing process. Based on the introduction of the related concept of circRNA, this paper focuses on the possible regulatory mechanism of circRNA in different stages of diabetic wound healing and summarizes the potential role of circRNA in the process of diabetic peripheral vascular atherosclerosis, aiming to explore the in-depth molecular mechanism and clinical significance of circRNA in diabetic wound healing process, and provide reference for further research.

Objective: We aimed to analyze the the genotyping of norovirus infectious diarrhea epidemic in Songjiang district, Shanghai, and explored the experience in handling the epidemic to provide a scientific basis for formulating prevention and treatment strategies. Methods: The epidemiological data and related samples of 69 outbreaks of infectious diarrhea caused by norovirus was collected from 2017 to 2019 in Songjiang district, Shanghai. Sequencing and type identification were performed by the method of gene sequencing for the junction region of Norovirus ORF1 and ORF2. Results: From 2017 to 2019, 69 outbreaks of norovirus infections diarrhea were reported in Songjiang district, Shanghai. A total of 1 767 samples were tested, including 619 case samples (positive rate 19.9%), 343 practitioner samples (positive rate 1.1%), 505 environmental samples (positive rate 0.5%) and 300 food samples (not detected). 141 sequences were obtained, and the genotype analysis showed that the genotype that mainly caused infectious diarrhea in 2017 and 2018 was GII.P16-GII.2 (50.98%, 26/51). In 2019, the genotypes that mainly caused infectious diarrhea were GII.P16-GII.2 (13.73%, 7/51) and GII.Pe-GII.4 (9.80%, 5/51). Conclusion: The main genotype of the 69 outbreaks of nororirus infectious diarrhea epidemic in Songjiang district, Shanghai from 2017 to 2019 was GII.P16-GII.2, which showed obvious peaks in spring, autumn and winter. There were more infections in kindergartens and schools. The surveillance of norovirus infection should be strengthened.

Candida albicans (Ca) is an important opportunistic pathogenic fungus found in the oral cavity, which plays an important role in oral microecological balance, and often interacting with other bacteria including Streptococcus mutans (Sm). Meanwhile, the characteristics of Ca such as adhesion, acidogenicity, aciduric nature and the ability to produce collagenolytic proteinases indicate its latent cariogenic potential. This review summarizes the research progress of the detectable rate of Ca in caries, its cariogenic potential and the interaction with Sm and other oral bacteria, in order to extend the understanding of pathogenesis of dental caries and to contribute new therapeutic and preventive strategies for dental caries.
