Effect evaluation of “healthy eating plate” based dietary management for diabetic inpatients / 预防医学

Objective@#To evaluate the effect of "healthy eating plate" based dietary management on diabetic inpatients.@*Methods@#The patients with type 2 diabetes mellitus (T2DM) admitted to Daishan First People's Hospital from November 2019 to November 2020 were selected and randomly divided into two groups. The intervention group was given "healthy eating plate" based dietary management, while the control group was given routine dietary management. Demographic data and physical examination results were collected. Fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), triglyceride (TG) and total cholesterol (TC) were detected at admission, discharge and 3 months after discharge, and compared between the two groups by covariance and generalized estimating equation. @*Results@#here were 52 patients aged (55.83±9.67) years in the intervention group, with 29 (55.77%) males and 23 (44.23%) females. There were 53 patients aged (57.54±11.09) years in the control group, with 32 (60.38%) males and 21 (39.62%) females. There were no significant differences in FPG, HbA1c, TG and TC levels between two groups at discharge (P>0.05). The level of HbA1c in the intervention group was significantly lower than that in the control group at 3 months after discharge (P<0.05); there were no significant differences in FPG, TG and TC levels (P>0.05).@*Conclusion @#The "healthy eating plate" based dietary management can better control the blood glucose of diabetic patients, and can help maintain the dietary treatment. It is worthy of promotion in diabetic patients.

REGγ is a strong candidate for the regulation of cell cycle, proliferation and the invasion by poorly differentiated thyroid carcinoma cells

REGγ is a proteasome activator that facilitates the degradation of small peptides. Abnormally high expression of REGγ has been observed in thyroid carcinomas. The purpose of the present study was to explore the role of REGγ in poorly differentiated thyroid carcinoma (PDTC). For this purpose, small interfering RNA (siRNA) was introduced to down-regulate the level of REGγ in the PDTC cell line SW579. Down-regulation of REGγ at the mRNA and protein levels was confirmed by RT-PCR and Western blot analyses. FACS analysis revealed cell cycle arrest at the G1/S transition, the MTT assay showed inhibition of cell proliferation, and the Transwell assay showed restricted cell invasion. Furthermore, the expression of the p21 protein was increased, the expression of proliferating cell nuclear antigen (PCNA) protein decreased, and the expression of the p27 protein was unchanged as shown by Western blot analyses. REGγ plays a critical role in the cell cycle, proliferation and invasion of SW579 cells. The alteration of p21 and PCNA proteins related to the down-regulation of REGγ suggests that p21 and PCNA participate in the process of REGγ regulation of cell cycle progression and cell proliferation. Thus, targeting REGγ has a therapeutic potential in the management of PDTC patients.
