Objective To probe into the imaging characteristics and regularity of color Doppler echocardiography(CDE) in congenital coronary artery fistula(CAF) in adults. Methods CDE was used to examine 31 adult patients with CAF and the imaging characteristics and regularity were observed. Angiocardiography was performed in 26 cases. Seven of the 31 cases were treated interventionally and 24 of them surgically. Results Of the 31 patients, 29 were correctly diagnosed according to the CDE characteristics (diagnosis accuracy was 93.5%) and all the complicated anomalies were correctly diagnosed. artery is the origin and whichever heart chamber is the entry site of the fistula, the left atrium and the left showed abnormal blood flow signals in the heart chamber into which the fistula drained and in pulmonary drained into the right ventricle was more common than that into the right atrium, the left atrium, the left or the pulmonary artery was easily misdiagnosed because left ventricular systolic pressure was equal to aortic pressure which made the abnormal blood flow in CDFI indistinct. Conclusions CDE showed obvious imaging characteristics and regularity for CAF in adults and has specific value for the diagnosis of this disease. But CAF that drained into the left ventricle or the pulmonary artery is easily misdiagnosed.

Objective To probe into the color Doppler echocardiographic characteristics of bilocular heart (BH) and associated malformations. Methods Twenty patients of BH were examined with color Doppler echocardiography (CDE) and the characteristics were observed. All the CDE results were compared with angiocardiography and 14 were confirmed by operation. Results Nineteen cases were properly diagnosed based on the CDE characteristics,1 case were misdiagnosed as mitral atresia. CDE characteristics of BH were obvious:① Apical four-chamber view of two-dimensional echocardiography (2DE) showed total echo dropout in both the interatrial septum and the interventricular septum and disappearance of the intracardiac "cross". The common atrioventricular valve closed during systole and appeared as figure "8", named 2DE "8" sign. During diastole, the common atrioventricular valve opened to a common ventricle. ② Color Doppler flow imaging (CDFI) showed common intra-atrial flow signal entereda common ventricle through common atrioventricular valve during diastole in all patients and colorful reflux through common atrioventricular valve during systole in 15 cases. ③ Among the 20 eases, 16 of the common atria were situs solitus,4 were situs inversus; 10 of the common ventricles were type A,2 were type B and 8 were type C. According to the spatial relationship of the great arteries,there were 4 type Ⅰ ,7 type Ⅱ and 9 type Ⅲ.There were 18 pulmonary stenosis and 2 pulmonary hypertension. ④ In the presence of pulmonary stenosis, CDFI showed colorful shunt signals through pulmonary artery during systole. Conclusions BH and associated malformations have obvious echocardiographic characteristics. CDE has a specific value in diagnosing BH and associated malformations.

Objective To explore the value of transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) in diagnosing adult multiple atrial septal defect (MASD). Methods Thirty adult patients with MASD were examined with TTE, 25 patients were examined also with TEE, 26 patients were examined with cardiac catheterization as well. Transcatheter closure of MASD was performed in 20 patients and succeeded in 18, while open-chest operation was performed in 4 patients. Results Foramen secundum atrial septal defect was diagnosed with both TTE and TEE with an accuracy rate of 60.00% (18/30) and 96.00% (24/25), respectively. The main color Doppler flow imaging (CDFI) feature of adult MASD was multiple colorful left-to-right shunt signals through the atrial septal designated, i.e. colander sign of CDFI. Conclusion TTE has some difficulties and TEE has specific value in diagnosing adult MASD. TTE can be used before open-chest operation. TEE is necessary before transcatheter occlusion to make sure of the amount and location of atrial septal defect.

This paper studied the diagnosis and embryology of 20 cases lacking one pulmonary artery out of 2040 patients operated for tetralogy of Fallot. History of severe cyanosis syncope and hemoptysis was usually present in the majority of these patients. The important diagnosis characteristic was asymmetry of plumonary vascularity on X-ray film and the decrease of pulmonary cascular markings on the side without plumonary artery. A right ventricular cardiogram can confirm the absence of one pulmonary artery or the blind-end like change.

OBJECTIVE: To study the effects and mechanism of couplet medicines of Scutellaria baicalensis-Paeonia lactiflora on improving ulcerative colitis (UC) in mice. METHODS: A total of 70 mice were randomly divided into blank group, model group, S. baicalensis group (1. 5 g/kg), P. lactiflora group (1. 5 g/kg), S. baicalensis-P. lactiflora (2:1, 1:1, 1:2, m/m) groups (total amount of 1. 5 g/kg), with 10 mice in each group. Except for blank group, UC model of mice was induced in each group. The next day after modeling, treatment groups were given relevant medicine liquid 0. 2 mL/10 g (75 mg/mL, calculated by crude drug mass concentration), while blank group and model group were given constant volume of normal saline intragastrically, once a day, for consecutive 7 d. After administration, disease activity indexes (DAI) of rats were scored, and the serum levels of TNF-α, IL-1β, IL-6, D-LA and myeloperoxidase (DAO) were determined. The length of the colon was measured and the intestinal mass index was calculated in mice. The activities of medullary peroxide (MPO) and SOD, the levels of NO and MDA were determined in colon tissue. RESULTS: Compared with blank group, DAI score, serum levels of TNF-α, IL-1β, IL-6, D-LA and DAO, the levels of MPO, NO and MDA in colon were increased significantly in model group, while the length of colon, intestinal mass index and SOD level of colon tissue were decreased significantly, with statistical significance (P<0. 05 or P<0. 01). Compared with model group, DAI score, serum levels of TNF-α, IL-1β and DAO, the level of MDA in colon were decreased significantly in S. baicalensis group (P<0. 05 or P<0. 01). The serum levels of TNF-α and IL-1β, the level of MDA in colon were decreased significantly in P. lactiflora group (P<0. 05 or P<0. 01). Above indexes of S. baicalensis-P. lactiflora (2:1) group were improved significantly except for the length of colon (P<0. 05 or P<0. 01). Above indexes of S. baicalensis-P. lactiflora (1:1) group were improved significantly except for serum level of IL-6 and the level of SOD in colon (P<0. 05 or P<0. 01). Above indexes of S. baicalensis-P. lactiflora (1:2) group were improved significantly except for serum level of NO (P<0. 05 or P<0. 01). CONCLUSIONS: The couplet medicines of S. baicalensis-P. lactiflora can reduce the expression of proinflammatory factors, enhancing antioxidant activity of the body and decrease intestinal mucosal permeability so as to improve UC symptom of mice; and the effect of S. baicalensis-P. lactiflora (2:1) group is the best.

Objective: This study used cardiac magnetic resonance imaging (MRI) to compare the characteristics of left ventricular remodeling in patients with primary aldosteronism (PA) with those of patients with essential hypertension (EH) and healthy controls (HCs). Materials and Methods: This prospective study enrolled 35 patients with PA, in addition to 35 age- and sex-matched patients with EH, and 35 age- and sex-matched HCs, all of whom underwent comprehensive clinical and cardiac MRI examinations. The analysis of variance was used to detect the differences in the characteristics of left ventricular remodeling among the three groups. Univariable and multivariable linear regression analyses were used to determine the relationships between left ventricular remodeling and the physiological variables. Results: The left ventricular end-diastolic volume index (EDVi) (mean ± standard deviation [SD]: 85.1 ± 13.0 mL/m2 for PA, 75.9 ± 14.3 mL/m2 for EH, and 77.3 ± 12.8 mL/m2 for HC; p = 0.010), left ventricular end-systolic volume index (ESVi) (mean ± SD: 35.2 ± 9.8 mL/m2 for PA, 30.7 ± 8.1 mL/m2 for EH, and 29.5 ± 7.0 mL/m2 for HC; p = 0.013), left ventricular mass index (mean ± SD: 65.8 ± 16.5 g/m2 for PA, 56.9 ± 12.1 g/m2 for EH, and 44.1 ± 8.9 g/m2 for HC; p < 0.001), and native T1 (mean ± SD: 1224 ± 39 ms for PA, 1201 ± 47 ms for EH, and 1200 ± 44 ms for HC; p = 0.041) values were higher in the PA group compared to the EH and HC groups. Multivariable linear regression demonstrated that log (plasma aldosteroneto-renin ratio) was independently correlated with EDVi and ESVi. Plasma aldosterone was independently correlated with native T1. Conclusion Patients with PA showed a greater degree of ventricular hypertrophy and enlargement, as well as myocardial fibrosis, compared to those with EH. Cardiac MRI T1 mapping can detect left ventricular myocardial fibrosis in patients with PA.
