ABSTRACT
Impaired glucose regulation(IGR,also named prediabetes)is an abnormal condition and important period for dia?betes mellitus. The period includes impaired fasting glucose or/and impaired glucose tolerance. IGR should be screened promptly and be interfered by life style and drugs to recover normal condition,or to delay and control the development of diabetes mellitus for de?creasing the highrisk of diabetes mellitus and cardiovascular disease. The paper reviews the literature about antiglycemic drugs and tra?ditional Chinese medicine interventions for IGR in China in the recent ten years,and summarizes some characters of these drugs to provide some help for prediabetes.
ABSTRACT
Objective To compare gemstone spectrum imaging (GSI) and auto mA technology for lower extremity arterial CTA to determine whether GSI can decrease radiation dose while increase image quality.Methods Thirty patients were equally divided into a GIS group and an auto mA group.All the patients underwent arterial CTA of both lower limbs.The auto mA group had the noise index (NI) being 15.48 and the current strength range from 20 to 400 mA,and the GSI group applied scanning protocol GSI-36 and 260 mA when used for arterial CTA.The values of CT dose index volumes (CTDIvol) and dose length product (DLP) were recorded,and the effect doses (ED) were calculated.The image quality was evaluated in the two groups,and statistical analysis was carried out.Results GSI and auto mA groups had CTDIvol values being (10.30±40.00) and (9.72±2.86) mGy,DLP values being (1 206.31 ±338.6) and (1 101.4±375.5) mGy· cm,and ED values being (18.10±5.08) and (16.52±5.63) mSv,respectively.The image quality score was (2.87±0.30) in GSI group and (2.57±0.46) in auto mA group,and there were significant difference between the scores (P＜0.05).Conclusion GSI cannot decrease X-ray radiation dose while increase image quality during lower extremity arterial CTA.

ABSTRACT
The article adopts the BP neural network and probability neural network in classifying four arrhythmias (LBBB, RBBB, Paced Beat, Ventricular Escape Beat) and one normal beat, and their test results of the automatic classification and imitation study are 97.62% and 95.88%, showing an improved efficient classification.
