Methods: A total of 186 patients with T2DM combined with MAFLD aged 27-75 years who were hospitalized in the Department of Endocrinology of Shijiazhuang People’s Hospital from September 2023 to August 2024 were selected. The patients were categorized into 80 cases in the non-severe hepatic steatosis group and 106 cases in the severe hepatic steatosis group according to the level of controlled attenuation parameter (CAP), which represents the severity of hepatic steatosis (S0: CAP γ-GGT, TG/HDL-C, and CAP were higher in the severe steatosis group than those in the non-severe steatosis group, and the differences were statistically significant (P γ-GGT, BMI, and TG/HDL-C (r-values of 0.407, 0.392, 0.422, 0.547, 0.381, 0.433, 0.368, 0.538, respectively, 0.568). (3) Binary logistic multifactorial regression analysis was performed to conclude that TG/HDL-C, LDL-C, BMI, and ALT were independent risk factors for hepatic steatosis in patients with T2DM combined with MAFLD (TG/HDL-C 95% confidence interval 1.726 (1.238, 2.407), P = 0.001). (4) Substituting TG/HDL-C, TG, LDL-C, and ALT into the ROC curve analysis, the areas under the curve were 0.753, 0.747, 0.609, and 0.695, respectively of which the sensitivity of TG/HDL-C was 54.7% and specificity 86.3%, both TG and TG/HDL-C could predict severe hepatic steatosis in patients with T2DM combined with MAFLD, but the predictive value of TG/HDL-C was superior (P = 0.000), which was statistically significant.展开更多
为提高蛋清蛋白凝胶性,本研究以蛋清蛋白(Egg white protein,EWP)为研究对象,通过分析质构、持水率、分子作用力、傅里叶红外色谱、圆二色谱、粒径、电位、巯基含量、表面疏水力及扫描电镜的变化,探究超高压处理(Ultra-high pressure,U...为提高蛋清蛋白凝胶性,本研究以蛋清蛋白(Egg white protein,EWP)为研究对象,通过分析质构、持水率、分子作用力、傅里叶红外色谱、圆二色谱、粒径、电位、巯基含量、表面疏水力及扫描电镜的变化,探究超高压处理(Ultra-high pressure,UHP)、谷氨酰胺转胺酶处理(Transglutaminase,TG)及超高压协同TG酶处理(Ultra-high pressure synergistic Transglutaminase,UTG)的蛋清蛋白热诱导凝胶机理及结构的变化。结果表明:UHP-EWP、TG-EWP、UTG-EWP的硬度、弹性和持水性均有所提高,疏水相互作用力是维持凝胶的主要作用力;UHP-EWP、TG-EWP、UTG-EWP的α-螺旋含量均不同程度下降、β-折叠含量均上升;UHP-EWP的平均粒径值下降、电位绝对值下降,TG-EWP、UTG-EWP的变化与之相反;UHP-EWP、TG-EWP、UTG-EWP的游离巯基含量上升、总巯基含量下降、表面疏水性升高;凝胶结构更加致密光滑,平整度提高。本研究为蛋清蛋白热诱导凝胶改性提供了理论基础及研究思路。展开更多
