ABSTRACT
Objective To summarize the characteristics of BI-RADS 4a breast diseases under ultrasonic examination referring to patients' clinical data and pathological reports.Methods 82 patients who were firstlydiagnosed and treated in the Affiliated Hospital of Jiangnan University were included.The ultrasonograms were retrospectively reviewed along with the correlated pathological and clinical findings.Results 48 (58.5％) cases were benign,among which fibroadenoma was the most common.34 cases (41.4％) were malignant,among which invasive ductal carcinoma was the most common.68 of the 82 cases were neoplastic disease (82.9％),6 (9.8％)were inflammatory disease,and 8(7.3％) were adenosis.Conclusions The patients who are graded BI-RADS 4a by ultrasonic examination may have completely different diseases.Beyond the most common benign diseases,few of them are malignancies with atypical,even ambiguous sonographic features.Therefore,in clinical practice,sonologists should set appropriate parameters of ultrasonic devices appropriately,and evaluate the sonographic features carefully,in order to make the correct grading and diagnosis.While for clinicians,it is necessary to learn to read the ultrasonographic features along with patients' manifestations,and finally reduce the misdiagosis and missed diagnosis of such diseases.
ABSTRACT
Objective To investigate the relationship between metabolic syndrome (MS) and diet style in the elderly. Methods The 781 old people were consecutively selected. Related data were collected by means of questionnaires and physical examinations. And logistic regression was performed to analyze if moderate and high fat diet were risk factors of MS. Results The total prevalence rate of MS in old people was 40. 7%, with 36.7% in old males and 55.4% in old females,and the prevalence rate of MS was higher in old women than in old men (P=0. 000). The significant differences in waist circumferences among three groups of low, moderate and high-fat diet [(86.0±9.3) cm vs. (88.8±8.5) cm vs. (90. 0±7.9) cm, respectively (all P＜0.05)]were found. Fasting blood glucose showed a significant difference between two groups of low and high-fat diet, with the results of (5.78 ± 0.98) mmol/L and (6.27 ± 1.80) mmol/L, respectively ( P＜0. 05 ). The logistic regression analysis showed that odds ratio for people with moderate and high-fat diets were 1. 541 ( 1. 092-2. 174) and 2. 293 ( 1. 317-3. 994), respectively (P＜0.05), which indicated that moderate and high-fat diet was independent risk factors for MS in old people. Conclusions Both moderate and high-fat diets are risk factors of MS in old population, low fat diet with food balance is recommended to old population in order to decrease the prevalence of MS.
ABSTRACT
Objective To investigate the relationship between metabolic syndrome (MS) and education level in Su-Xi-Chang area to provide evidence for healthcare policy making. Methods A clustered sampling of 6798 subjects from Su-Xi-Chang areas of Jiangsu Province was included. Questionnaires and physical examinations were completed to collect clinical data. Logistic regression was used to analyze weather education level could be an independent risk factor of MS. Results Significant differences were found in waist circumstance (WC) ,systolic blood pressure (SBP) and fasting blood glucose (FBG) among participants with different education level. Significant differences were also existed in triglyceride and diastolic blood pressure (DBP) between subjects with higher and lower education level ( P＜0. 05 ). In single-factor or multivariate analysis, education level was negatively correlated with the prevalence of MS (P＜0. 05 ). Conclusions Education level may be an independent risk factor of MS. People with low and moderate education level have higher risk of MS. Therefore,it is recommended that health-related information should become an integral part of the compulsory education system.
