OBJECTIVETo investigate the polymorphism of FcgammaRIIIb genotype, IgG G2m(23) factor and their associations with the susceptibility to aggressive periodontitis.

METHODSDNA of white blood cells and serum from 21 aggressive periodontitis patients and 26 healthy controls was extracted. Genotype of FcgammaRIIIb and phenotype of G2m(23) factor was determined by allele-specific PCR and dot immunobinding assay respectively.

RESULTSThe frequency of FcgammaRIIIb-NA1/NA1 genotype in aggressive periodontitis patients was significantly higher than in healthy controls (P < 0.05). The ratio of subjects with FcgammaRIIIb-NA1/NA1 genotype and positive G2m(23) factor was higher in aggressive periodontitis patients (11/21) than in health controls (5/26) (P < 0.05). However, no statistical difference in distribution of G2m(23) factor alone was observed between patients and controls.

CONCLUSIONSThis study indicates that FcgammaRIIIb-NA1/NA1 genotype may be a susceptible genotype to aggressive periodontitis in Chinese population. Subjects with FcgammaRIIIb NA1/NA1 genotype and positive G2m(23) factor may be more susceptible to aggressive periodontitis.

Increasing studies have demonstrated that interferon gamma (IFN-γ),which serves as a critical inflammatory cytokine,is essential to induce the immunosuppressive effects of mesenchymal stem cells (MSCs).However,the mechanisms underlying the enhanced immunosuppressive effects of IFN-γ-stimulated MSCs (γMSCs) are not fully understood.MSC-derived rnicrovesicles (MSC-MVs) have been viewed as potential pivotal mediators of the immunosuppressive effects of MSCs.Moreover,microRNAs (miRNAs) are important regulators of immunological processes and can be shuttled from cell to cell by MVs.The aim of our study was to analyze the the miRNA expression signature of MVs derived from γMSCs (γMSC-MVs),which may provide better understanding of the immunosuppressive property of their parent cells.Through miRNA microarray and bioinformatics analysis,we found 62 significantly differentially expressed miRNAs (DEMs) in γMSC-MVs compared with MSC-MVs.And the potential target genes and signaling pathways regulated by DEMs were predicted and analyzed.Interestingly,many DEMs and predicted signaling pathways had been.demonstrated to be involved in immunoregulation.Furthermore,the network between immunoregulation-related pathways and relevant DEMs was constructed.Collectively,our research on the miRNA repertoires of γMSC-MVs not only provides new perspectives into the mechanisms underlying the enhanced immunosuppressive property of γMSCs,but also paves the way to clinical application of these potent organelles in the future.

Objective:To deeply explore the real experience, source and coping style of stigma in patients with diabetic foot, so as to provide a reference for nurses to formulate targeted intervention measures.Methods:From January to April 2021, 12 diabetic foot patients from the Department of Endocrinology, the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine were selected as the research object by objective sampling. The in-depth patient interview was conducted using the phenomenological method in qualitative research. The interview data were analyzed according to the Colaizzi 7-step analysis in phenomenology, and the themes were refined with the Nvivo 12.0.Results:The stigma experienced by diabetic foot patients was grouped into three themes. Theme one was the real experience of stigma, including shame, anxiety, depression, self-blame and regret, and low self-esteem. Theme two was the source of stigma, including family, friends and colleagues, media, and treatment costs. Theme three was stigma coping styles, including positive response, concealment, avoidance, and rejection.Conclusions:Diabetic foot patients have a strong sense of stigma and cannot take effective coping styles. Medical and nursing staff and family members of patients should pay full attention to the stigma of diabetic foot patients and provide them with nursing interventions and psychological support.

At present, the traditional models for cancer research include the 2D cell model, human tumor xenograft model and animal model. With the deepening of research, the traditional tumor model is unable to meet the needs of researchers. Organoid model is derived from the surgical specimens of tumor patients, which can completely preserve the histological and genomic characteristics of tumor. It can be used in the research of tumor pathogenesis, drug screening, personalized treatment of patients, etc. Compared with traditional model, it has the advantages of short modeling time, economic benefits and closer-ness to the characteristics of the original tumor. This paper mainly focuses on the research status of organoid technology in tumor, the application of organoid model in treatment, and the advantages of organoid model compared with traditional model, so as to provide reference for the follow-up research.

Taenia pisiformis is one of the most important parasites of canines and rabbits. T. pisiformis cysticercus (the larval stage) causes severe damage to rabbit breeding, which results in huge economic losses. In this study, the genetic variation of T. pisiformis was determined in Sichuan Province, China. Fragments of the mitochondrial cytochrome b (cytb) (922 bp) gene were amplified in 53 isolates from 8 regions of T. pisiformis. Overall, 12 haplotypes were found in these 53 cytb sequences. Molecular genetic variations showed 98.4% genetic variation derived from intra-region. F(ST) and Nm values suggested that 53 isolates were not genetically differentiated and had low levels of genetic diversity. Neutrality indices of the cytb sequences showed the evolution of T. pisiformis followed a neutral mode. Phylogenetic analysis revealed no correlation between phylogeny and geographic distribution. These findings indicate that 53 isolates of T. pisiformis keep a low genetic variation, which provide useful knowledge for monitoring changes in parasite populations for future control strategies.
