ABSTRACT
The 81st annual scientific meeting of the American Diabetes Association (ADA) was held online from June 25 to 29, 2021. The conference encompassed following theme areas: Acute and chronic complications of diabetes, behavioral medicine, clinical nutrition, education and exercise, clinical diabetes/therapeutics, epidemiology/genetics, immunology/transplantation, insulin action/molecular metabolism, integrated physiology/obesity and islet biology/insulin secretions, which covers both clinical and basic aspects of diabetes mellitus and other metabolic diseases. Here is the summary of the main points of academic progress in diabetes and other metabolic diseases.
ABSTRACT
Chronic inflammation,oxidative stress and retinal ganglion cell apoptosis play important roles in the development of diabetic retinopathy.Fenofibrate,a peroxisome proliferator-activated receptor α agonist,is used for dyslipidemia.In addition to its lipid-modulating effects,fenofibrate also has antiinflammatory,antioxidant,anti-apoptotic and anti-angiogenesis properties that may be useful to delay the progression of diabetic retinopathy.Some clinical studies have already confirmed that fenofibrate has therapeutic effect on diabetic retinopathy.Further studies the application of fenofibrate in the treatment of diabetic microangiopathy to clarify the safety and efficacy of fenofibrate is of great significance.
ABSTRACT
Objective To compare the accuracy rate of talar osteochondral lesions between the small field of view (FOV) surface coil MR imaging and 2D FSE proton density weighted imaging (2D-FSE-PD),3D-SPACE sequences MR imaging with boot-shaped coil.Methods Totally 43 patients (45 ankles) underwent 3D-SPACE sequence after 2D-FSE-PD sequence scanning using the boot-shaped coil,then the PDWI sequence was scanning after the boot-shaped coil was replaced by the small FOV surface coil at 1.5T MRI.The results of the arthroscopic examinations was regarded as the standard for assessing the accuracy rate of the three methods.Results The accuracy rate of 2D-FSE-PD sequence with small FOV surface coil was 86.67％ (39/45),the accuracy rate of 2D-FSE-PD sequence with boot coil was 60.00％ (27/45),the accuracy rate of 3D-SPACE sequence with boot coil was 68.89％ (31/45).The accuracy rate of small FOV surface coil was higher than those of boot coil used 3D-SPACE sequence (x2 =4.114,P =0.002) and boot coil used 2D-FSE-PD sequence (x2 =8.182,P＜0.001).There was not significant difference between 3D-SPACE sequence using boot coil and 2D-FSE-PD sequence using boot coil (x2 =0.776,P=0.125).Conclusion Compared with the 2D-FSE-PD and 3D-SPACE sequences with boot-shaped coil,the small surface coil scanning with routine sequence can show talar osteochondral lesions better.
