Objective:To explore the application effect of target management model based on standardized Metabolic Management Center (MMC) in newly diagnosed diabetic patients.Methods:A total of 80 inpatients who were newly diagnosed as diabetes mellitus in Department of Endocrinology and Metabolism in Affiliated Hospital of Jiangsu University from October 2018 to March 2019 were selected as the convenient sampling method. According to the random number table method, they were divided into the observation group and the control group, with 40 cases in each group. The control group was given routine nursing management while the observation group was given target management by using supporting facilities of MMC based on the control group. The changes of fasting plasma glucose (FPG) , 2 h postprandial blood glucose (2hPG) , glycated hemoglobin (HbA1c) , body mass index (BMI) and self-management behavior scores before and after 6 months of intervention were compared between the two groups.Results:There were no statistically significant differences in blood glucose index, BMI and self-management behavior score between the two groups before the intervention ( P>0.05) . After intervention, the blood glucose and self-management behavior scores of the observation group were better than those of the control group, and the differences were statistically significant ( P<0.05) . The BMI of observation group after intervention was lower than that before intervention, and the difference was statistically significant ( P <0.05) . There was no statistically significant difference before and after intervention in the control group ( P>0.05) . Conclusions:Target management based on the MMC is conducive to improving the self-management ability of newly diagnosed diabetic patients and helps them to effectively control blood glucose and body weight.

Morinda genus of Rubiaceae has been widely used in medicine at home and abroad. Many parts of Morinda tree are utilized in research, mainly including roots, stems, leaves, branches and seeds. Through the research of online databases, the chemical components and biological activities of the iridoids in Morinda genus were summarized in this paper. Up to now, more than 50 kinds of iridoids have been identified. In addition, more and more studies proved that Morinda iridoids might benefit human via such anti-inflammatory, antinociceptive, anti-oxidation, anti-tumor and bone protection. The theoretical basis was provided for the further development and utilization of the iridoids in Morinda genus.

As main recipient cells for porcine reproductive and respiratory syndrome virus (PRRSV), porcine alveolar macrophage (PAM) are involved in the progress of several highly pathogenic virus infections. However, due to the fact that the PAM cells can only be obtained from primary tissues, research on PAM-based virus-host interactions remains challenging. The improvement of induced pluripotent stem cells (iPSCs) technology provides a new strategy to develop IPSCs-derived PAM cells. Since the CD163 is a macrophage-specific marker and a validated receptor essential for PRRSV infection, generation of stable porcine induced pluripotent stem cells lines containing CD163 reporter system play important roles in the investigation of IPSCs-PAM transition and PAM-based virus-host interaction. Based on the CRISPR/Cas9- mediated gene editing system, we designed a sgRNA targeting CD163 locus and constructed the corresponding donor vectors. To test whether this reporter system has the expected function, the reporter system was introduced into primary PAM cells to detect the expression of RFP. To validate the low effect on stem cell pluripotency, we generated porcine iPSC lines containing CD163 reporter and assessed the pluripotency through multiple assays such as alkaline phosphatase staining, immunofluorescent staining, and EdU staining. The red-fluorescent protein (RFP) expression was detected in CD163-edited PAM cells, suggesting that our reporter system indeed has the ability to reflect the expression of gene CD163. Compared with wild-type (WT) iPSCs, the CD163 reporter-iPSCs display similar pluripotency-associated transcription factors expression. Besides, cells with the reporter system showed consistent cell morphology and proliferation ability as compared to WT iPSCs, indicating that the edited-cells have no effect on stem cell pluripotency. In conclusion, we generated porcine iPSCs that contain a CD163 reporter system. Our results demonstrated that this reporter system was functional and safe. This study provides a platform to investigate the iPS-PAM development and virus-host interaction in PAM cells.
