In order to investigate the interelationship between copper deficiency and lipidemia, an experiment was done in weanling rats fed normol and copper deficient diet for one month. At the end of experimental period, the growth rate, the contents of copper, zinc, cholesterol and triglyceride in plasma and the activity of monoamine oxidase (MAO) in plasma were measured. The differences between the two diets were compared by student's test and the relation between plasma copper and plasma cholesterol or MAO was ascertained by regression analysis.The results showed that a lower body weight gain and a highly significant hypercholesterolemia were found in copper deficiency rats and the plasma cholesterol concentration correlated reversely with the plasma copper (r = -0.724, p

Objective To observe the influence of phentolamine on N terminal B-type natriuretic peptide precursor(NT-proBNP),blood gas analysis,hypersensitive c-reactive protein and plasma D-dimer in patients with chronic cor pulmonale Methods One hundred and one cases patients with chronic cor pulmonale were randomly divided into two groups,51 patients in the treatment group,50 patients in the control group.All patients were treated with normal anti-infection,eliminating phlegm to smooth wheezing antithrombotic for one week,as the same time patients in the treatment group were treated with phentolamine for one week.Through observed the treatment effect of phentolamine to chronic cor pulmonale,the level of NT-proBNP,blood gas analysis,hypersensitive c-reactive protein and plasma D-dimer in patients with chronic cor pulmonale before and after the treatment were analyzed.Results Compared with before treatment,the levels of NT-proBNP,PCO2,hypersensitive c-reactive protein,plasma D dimer were lower than after one week in two groups,while the level of PO2 was higher.Treatment group:NT-proBNP (1 712.76±572.32) ng/L vs.(271.59±163.05) ng/L,t=20.42,P<0.05,PCO2 (66.34±5.81) mmHg vs.(52.58±5.82) mmHg,t=16.46,P<0.05,PO2 (59.28±6.13) mmHg vs.(73.64±6.10) mmHg,t=23.02,P<0.05,hypersensitive c-reactive protein 86.0(28.0) mg/L vs.23.0(12.0) mg/L,Z=-6.22,P<0.05 mg/L,plasma D-dimer (4 953.37±1 654.09) μg/L vs.(1 847.90±838.66) μg/L,t=17.11,P<0.05.Control group:NT-proBNP (1 527.24±658.70) ng/L vs.(612.58±357.59) ng/L,t=14.52,P<0.05,PCO2 (65.41±5.23) mmHg vs.(56.46±5.65) mmHg,t=13.04,P<0.05,PO2(60.57±5.84) mmHg vs.(67.21±5.19) mmHg,t=-10.06,P<0.05,hypersensitive c-reactive protein 79.0(29.0) mg/L vs.43.0(20.0) mg/L,Z=-6.16,,P<0.05,plasma D-dimer (4 408.02±1 682.83) μg/L vs.(2 598.28±1 242.73) μg/L,t=12.15,P<0.05.But the levels of NT-proBNP,PCO2,hypersensitive c-reactive protein and plasma D-dimer reduced significantly,the level of PO2 increased more significantly in treatment group(t(z)=-6.19,-3.39,-7.16,-3.56,5.70,all P<0.05).Conclusion Phentolamine can reduce the level of NT-proBNP,PCO2,hypersensitive c-reactive protein and plasma D-dimer and increased the level of PO2 in patients with chronic cor pulmonale.Phentolamine combined with routine treatment can improve the clinical efficacy of patients with chronic cor pulmonale.

Objective: To explore a single center large cohort of patients with Takayasu’s arteritis for their clinical manifestation and long-term outcome in China. Methods: We retrospectively analyzed 566 patients with Takayasu’s arteritis admitted in our hospital from 2002-01 to 2013-11 for their clinical characteristics, laboratory ifndings, angiographic features, treatment and long-term outcomes. Results: The patient’s ratio for female to male gender was 1 to 3.8 and the average onset age was (28.9 ± 12.0) years. The most common non-speciifc symptom, initial symptom and complication were fever (52/566 patients, 9.2%), dizziness (214 patients, 37.8%) and hypertension (392 patients, 69.3%) respectively. The patients with pulmonary artery and coronary artery involvement were 83 (14.7%) and 66 (11.7%) respectively, and 131 (23.1%) patients had faster erythrocyte sedimentation rate. The major vascular damage was steno-occlusive lesion and the most common involvement was left sub-clavian artery, which was observed in 278 (49.1%) patients. The treatments were mainly included in medication, interventional therapy, autologous blood vessel transplantation, artiifcial blood vessel transplantation and aortic valve replacement. There were 32 patients died during the mean follow-up period of (5.0 ± 0.2) years. Hypertension, complication and the progressive stage of disease were the major factors affecting prognosis in relevant patients (regression coefifcients: 4.664, 1.959 and 1.870 respectively, allP<0.05). Conclusion: Hypertension was the leading reason for patients’ hospital visit. Takayasu’s arteritis was closely related to cardiovascular disease, the early diagnosis and treatment were really important in clinical practice.

Objective: To explore the clinical features and prognosis in patients with Takayasu arteritis (TA) combining neurological symptoms. Methods: We retrospectively studied 274 TA patients combining neurological symptoms who admitted to our hospital from 2002-01 to 2013-10 for their clinical and imaging features with prognosis. Results: The ratio of male to female was 1:4.3 and the mean age of disease onset was at (28.2±11.2) years. The most common neurological symptom was dizziness (214/274 cases, 78.1%), most frequent type was type III TA (112 cases, 40.9%), most common affected artery was left subclavian artery (147 cases, 53.6%), and there were 77 cases (28.1%) with (3-4) branches of the aortic arch involvement. For stroke conditions, ischemic stroke was more frequently observed in patients with steno-occlusive lesions in subclavian artery and common carotid artery, while hemorrhagic stroke was more frequently found in patients with steno-occlusive lesions in descending aorta, abdominal aorta and/or renal artery. Heart failure was the most common cause of death, it was also the most common cardiovascular event in surviving cohorts. Conclusion: TA patients could have many neurological symptoms, which were related to the number and site of artery involvement.
