ABSTRACT
Objective To evaluate the metabolic characteristics of insulin secretion and insulin sensitivity in isolated postchallenge hyperglycemia(IPH) and to clarify the factors responsible for the development of IPH. Methods(Eight hundred) and fifty subjects were classified into the following three groups based on the results of a 75-g oral glucose tolerance test(OGTT): normal glucose tolerance(NGT),n=557;isolated impaired glucose tolerance(iIGT),n=146;and IPH,n=147.Insulin secretion(insulinogenic index) and insulin sensitivity(insulin sensitivity index) were identified in the three groups. Results From NGT to iIGT and IPH in these subjects,the insulinogenic index and insulin sensitivity index were gradually decreased(P
ABSTRACT
Objective To investigate the clinical application value of the modified radiography by digital ra- diography of the tempro-mandibular joint in the tempro-mandibular joint radiography.Methods A digital radiogra- phy machine(Siemens Aristos MX)was used to the tempro-mandibular joint disorders of 68 patients with the meth- ods of the modified radiography of the tempro-mandibular joint,and the results were compared with those of 45 cases acquired with conventional radiography.Results The modified radiography by digital radiography provided high res- olution,precise location and excellent images,and the total structures of tempro-mandibular joint was clearly dis- played,with a success rate of 99%(67/68),while the results acquired by conventional radiography were not clear, only with a success rate of 60%(18/45).There is significant statistical differences between the modified radiography by digital radiography and conventional radiography(x~2 = 35.08,P
