Kawasaki disease,also known as multiple mucocutaneous lymph node syndrome,is a self-limiting and acute systemic vasculitis.Kawasaki disease is often complicated by coronary artery lesions.Kawasa-ki disease is a leading cause of coronary artery lesions in childhood in developed countries.The mechanisms of coronary artery lesions and new therapeutic regimens have been the hotpots in research of Kawasaki disease.This paper reviews current research on mechanism of coronary artery lesions and development of new therapeutic regi-mens.

The capsule possesses the properties of benefitting Qi, nourishing Yin and activating blood circulation and eliminating stasis. It improves fat metabolism, stimulates function of pancreatic islets, lowers blood glucose as well as alleviates clinical sym(?)oms, with satisfactory results on vascular complications. Improvements also include left myocard(?)l anoxia, left heart function, cerebral blood ci(?)ulation, dilatation of arteries in lower limbs, with anticoagulation and thrombolytic effect.It also reveals certain effect on diabetic nephropathy and early diabetic retinosis.

ObjectiveTo investigate the relationship between microtubule-associated protein l light chain 3B (LC3-II) and the inlfammatory response of Kawasaki disease (KD).MethodsThirty-nine cases of acute KD before intravenous admin-istration of immunoglobulin were enrolled. According to the results of echocardiography, the 39 cases were furtherly divided into KD with coronary artery lesion (CAL, 20 cases) group and KD with non-CAL (NCAL, 19 cases) group. At the same time, 12 healthy children were selected as controls. Serum samples were collected and cultured in vitro by human coronary artery endothe-lial cells (HCAEC) for 12 h. The LC3-II protein and mRNA expression of HCAEC were detected by Western-blotting and Q-PCR respectively.ResultsThe LC3-II protein and mRNA expression in CAL group and NCAL group were signiifcantly higher than those in control group, the LC3-II protein and mRNA expression in CAL group was higher than those in NCAL group, and both differences were statistically signiifcant (P<0.05).ConclusionsAutophagy may be involved in the inlfammatory response of KD in acute phase, which may be related to endothelial cell lesions of coronary artery in children with KD.

Objective To detect serum antinuclear antibody (ANA) with enzyme-linked immunosorbent (ELISA) and linear immunoblot technique (LIA) and to evaluate and compare the performance of two methods in auxiliary diagnosis of systemic lupus erythematosus (SLE). Methods ANA detected by both ELISA and LIA of 597 cases were collected in the last two years. The results were retrospective analyzed. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and the consistency of the two methods were compared and analyzed. Results The sensitivity of ELISA and LIA was 79.3% and 86.6% respectively for SLE patients; specificity 81.7% and 77.3%; accuracy 81.4% and 78.6%, positive predictive value 40.9%, and 37.8%;negative predictive value 96.1% and 97.3% respectively. No significant difference was found between the two methods (P > 0.05). The results showed that the coincidence rate was 81.4%, and the Kappa test 0.55. The Kappa test of the two methods in SLE group was 0.403. Conclusion No statistical significance is found in the comparison of ELISA method and LIA method to detect ANA for the diagnosis of SLE and the combination of two kinds of detection method has important application value.
