Fetal Hemodynamics and Fetal Growth Indices by Ultrasound in Late Pregnancy and Birth Weight in Gestational Diabetes Mellitus.

Background: The offspring of women with gestational diabetes mellitus (GDM) are prone to macrosomia. However, birth weight is difficult to be correctly estimated by ultrasound because of fetal asymmetric growth characteristics. This study aimed to investigate the correlations between fetal hemodynamics, fetal growth indices in late pregnancy, and birth weight in GDM.

[Diagnostic values of breast imaging and reporting data system and ultrasonic elastography for benign and malignant breast lesions].

Objective: To explore the diagnostic values of breast imaging and reporting data system (BI-RADS) and ultrasonic elastography (UE) for benign and malignant breast lesions.

Methods: A total of 122 breast lesions were studied with BI-RADS and UE scoring to compare the sensitivity and specificity according to the pathologic results. Receiver operating characteristic (ROC) curves were used to assess the diagnostic value of BI-RADS, UE and combination.

[The application value of BI-RADS lexicon and high-frequency CDFI scoring in differentiation of benign from malignant lesions of the breast].

Objective: To explore the diagnostic value with BI-RADS lexicon and high-frequency color doppler ultrasonic scoring for breast diseases.

Methods: A total of 108 breast lesions were studied with BI-RADS lexicon and high-frequency color doppler ultrasonic scoring, and compared with pathologic results. Calculated the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value.

Prevalence and risk factors for diabetic retinopathy: the Beijing Communities Diabetes Study 6.

Background: To examine prevalence and associated factors of diabetic retinopathy in patients with Type 2 diabetes mellitus in urban communities of Beijing.

Methods: The community health care center-based study included subjects with diabetes mellitus and an age of 20 years to 80 years, who were recruited from 15 community health centers in urban Beijing. Diabetes mellitus was defined using the World Health Organization criteria.

Neck circumference positively related with central obesity, overweight, and metabolic syndrome in Chinese subjects with type 2 diabetes: Beijing Community Diabetes Study 4.

Objective: To investigate the association between neck circumference and central obesity, overweight, and metabolic syndrome in Chinese individuals with type 2 diabetes.

Research Design And Methods: A total of 3,182 diabetic subjects (aged 20-80 years) were recruited from 15 community health centers in Beijing using a multistage random sampling approach.

Results: Receiver operating characteristic analysis showed that the area under the curve for neck circumference and central obesity was 0.
