Objective To explore the value of ductus arteriosus in ultrasound diagnosis of fetal congenital heart disease by echocardiography. Methods The fetal echocardiography was performed with three segments diagnosis method. According to the fetal position, the ductus arteriosus was examined in different sections which include the V shape sign section formed by ductus arteriosus and right pulmonary artery,the V shape sign section formed by ductus arteriosus and the gorge of aortic arch,the three fingers sign section formed by ductus arteriosus,left and right pulmonary artery,the Z shape sign section formed by left pulmonary artery, ductus arteriosus and the gorge of aortic arch. The flow velocity and the inner diameter of the ductus arteriosus were measured. Results Thirty-one cases with congenital heart disease were evaluted. Thirteen cases were approved by autopsy. Among those fetus, 4 cases went with ductus arteriosus stenosis and they all accompanied with right heart obstructing disease,3 cases went with dilated ductus arteriosus and they all accompanied with left heart obstructing disease. Retrograde were explored in 2 fetus. The flow velocity of 5 fetus ductus arteriosus were higher than the normal fetus and 4 cases of them with right heart obstruction, 1 cases with left heart obstruction. Five fetal ductus arteriosus were normal. One fetal ductus arteriosus was absent. Conclusions Assessant of ductus arteriosus by echocardiography is an important content in screening fetal congenital heart disease. It can help us to diagnose quickly.

Objective To analyze the ultrasound findings of urinary calculi caused by melamine. Methods The urinary system of totally 5337 children were examined with high frequency convex ultrasound probe,the characteristics of the images were analysed. CT plain scan method was used when ultrasound result was in difficulty. Results There were 360 cases with calculus in the 5337 children. In the 360 cases, unilateral calculus was in 92 cases, bilateral calculus in 48, bladder stone in 3, urethra stone in 1, kidney calcium deposition in 2, suspicion stone in 214 cases, urinary obstruction in 28 of them. The size of the stones ranged from 3 mm×2 mm to stag-horn calculus. Conclusions The urinary calculi caused by melamine is sandy stone. Ultrasound result is equivocal in the disease, CT plain scan can be a method of choice. High frequency convex probe provides more clear images, more evident adminstrative levels of anatomise than general abdominal probe does. It is beneficial for diagnosing and differential diagnosing of these diseases.

Objective To explor the ultrasonography methodology of the fetal ductus arteriosus.Methods Based on the fetal four-chamber sight, the characteristic ultrasound images were observed by moving probe,such as "V-shape" sign,"three-finger" sign,"Z-shape" sign and"hockey-handle" sign making up of the ductus arteriosus and the nearby structures were observed by moving probe. The inner diameter,the systole flow velocity,the diastole flow velocity and the resistance index of the ductus arteriosus via the "V-shape" sign section were measured. Results Among the 365 normal fetus cases,355 "V-shape" sign cases,237 "three-finger" sign cases,298 "Z-shape" sign cases and 331 "hockey-handle" sign cases were identified. The inner diameter of the fetal ductus arteriosus increases gradually with the growth of the gestational weeks and the flow velocity increases gradually too, while the resistance index had no obvious variation with the growth of the gestational weeks. Conclusions According to the characteristic ultrasound images, such as "V-shape" sign, "three-finger" sign, "Z-shape" sign and "hockey-handle" sign, the fetal ductus arteriosus can be identified promptly.

Objective To study the curative effect and safety of senile osteoporotic vertebral compression fractures with balloon ky-phoplasty. Methods The clinical data of 80 patients in our hospital during July 2008 to July 2012 with senile osteoporotic vertebral compres-sion fractures were analysed retrospectively. And the clinical effect was evaluated by observing the charges of visual analog scale (VAS), height of vertebral bodies and Cobb’ s angle, the quality of life score in patients respectively before and after operation. Results The pain of the patients were controlled effectively after operation, and the patients had significant and sustained improvement in anterior and midline ver-tebral body height after operation, with (56. 02 ± 12. 08) % and (58. 19 ± 13. 11) % before preoperation respectively, and (72. 10 ± 16. 19) % and (78. 33 ± 19. 02) % after surgery respectively. VAS score reduced from (8. 31 ± 1. 22) to (1. 65 ± 0. 33) after surgery;Cobb’s angle reduced from (24. 12 ± 3. 28)° to (13. 56 ± 2. 05)° after operation. The differences of the frontal height and flange height, VAS scores, and Cobb’s angle before and after operation were statistically significant (P<0. 05). The incidence of complications reduced from 23. 75% to 1. 25% after operation, which indicates significant difference (P<0. 01). According to QLQC-30 quality of life score, the postoperative life of patients were much better than that of the preoperative life, and the difference of all statistical index were of statistical significance (P<0. 05). Conclusion Balloon kyphoplasty in the treatment of senile osteoporotic vertebral compression fractures has signifi-cant effect and high safety, it should be popularized and applied in clinical.

Objective To investigate certain risk factors for and their impact on abnormal liver function in middle-aged and elderly adults.Methods A case-control study was constructed based on the SAGE cohort of 8642 registered residents aged 50 years or over in Shanghai.Of them,137 individuals with abnormal liver function,defined as aspartate transaminase (AST)＞ 40 U/L or alanine aminotransferase (ALT)＞ 40 U/L,were randomly selected as the observation group,while 411 healthy controls were 3 ∶ 1 matched with the cases in the observation group by gender and age (1 year).Face-to-face administered questionnaires and physical examinations were conducted and serum samples were tested for ALT,AST,glucose (GLU),total cholesterol (TC),triglycreide (TG),hepatitis B surface antigen (HbsAg) and anti-hepatitis C virus antibody (anti-HCV Ab).Chi square test and rank sum test were used for single factor analysis,and logistic regression analysis was used for multiple factors.Results The prevalence of HBsAg positive patients was 12.4 ％ (68/548) Univariate analysis showed that hepatitis virus infection and body mass index (BMI) were associated with abnormal liver function (both P＜0.000).Multivariate logistic regression analysis showed that hepatitis virus infection (OR=1.85,95％ CI:1.04 3.29,P-0.036) and obesity (OR=3.60,95％CI:1.92-6.73,P＜0.001) increased the risk of abnormal liver function,whereas chronic medication (OR=0.51,95％ CI:0.32-0.80,P =0.004) decreased the risk of abnormal liver function.Conclusions Among the study population,hepatitis virus infection and obesity are risk factors for abnormal liver function in middle-aged and elderly people.After adjustment for potential confounders,chronic medication is negatively correlated with abnormal liver function and may be a protective factor for liver function.
