AIM:To investigate the injurious effects of oxidized low-density(OLDL) on human endothelial cells(ECs) and protective effects of Angelica Sinensis in vitro. METHODS: The effect of OLDL on nitric oxide (NO) release from EC and intercellular adhesion molecule-1 (ICAM-1) expression on EC surface were studied, and the protective effects of Angelica Sinensis on normal and abnormal EC were investigated using cultured EC with or without OLDL and immunocytochemical staining technique. RESULTS: OLDL led to a decrease of NO release and an increase of ICAM-1 expression, which can be reversed by Angelica Sinensis and atropine can block this role of Angelica Sinensis. CONCLUSION: Angelica Sinensis has antagonistic effect on OLDL-induced decreasing of NO released from ECs and increasing of ICAM-1 expression on ECs surface . These effects of Angelica Sinensis may be exerted by the excitation of muscarinic receptor.

Objective To explore the relationship between cardiac involvement and laboratory indicators in patients with rheumatoid arthritis(RA). Methods Cardiac echocardiography and ECG performance of 184 patients with RA were analyzed retrospectively. Results Among the 184 patients with RA, the pulmonary hypertension detection rate was 8. 3%, valvular disease 38. 9%, arteriosclerosis 27. 8%, wall to reduce the exercise 13.9%, myocarditis 5.6% and pericardial effusion 5.6%, according to the echocardiography examinations;Sinus tachycardia was evidenced in 15. 22% patients, ST-T changes in 39. 13%, electric axis left side in 8. 70%, branch block in 13.04%, left ventricular hypertrophy in 4. 35%, atrial fibrillation in 4. 35%, premature in 8.70%, early repolarization syndrome in 2. 17% and electric-axis right side in 4. 35% patients by ECG examinations. The serum level of CRP (46. 77 ±5. 87) mg/L was significantly higher in RA patients with cardiac involvement than that in the non-cardiac involvement patientsm (28. 45 ±3. 21) mg/L (P <0.05) ;While the serum level of ESR,RF,IgG,IgA,IgM, PLT showed no statistically significant differences between the two groups (P > 0.05); Within RA patients withcardiac involvement, the serum level of CRP showed no significant difference among different sub-groups , which were classified according to the echocardiography performance (P > 0.05). Conclusions Cardiac involvement occurred frequently in patients with rheumatoid arthritis. The valvular disease, arteriosclerosis, reducing of the wall motion and pericardial effusion are the main manifestations by echocardiography examination; Sinus tachycardia, ST-T changes,branch block and premature beats are the main ECG abnormalities. The serum level of CRP is significantly higher in RA patients with cardiac involvement than that with non-cardiac involvement patients. The higher level of CRP in patients with RA may indicate the cardiac involvement presence.
