Atrial fibrillation (AF) is the most common clinical arrhythmia.Atrial electrical remodeling and structural remodeling are the important mechanisms for AF.The intracellular Ca2+ handling abnormalities play an important role in the induction of triggered ectopic activity and in the activation of Ca2+-related cell signaling which mediates fibrillatory remodeling.In addition,the importance of microRNAs,which are a new class of small noncoding sequences that regulate gene expression,has been found in both electrical and structural remodeling.The new discovery of AF mechanisms are helpful to exploring the effective treatment for AF,showing good prospects for the use of translational perspectives.

Objective: To study the chemical constituents from flowers of Carthamus tinctorius. Methods: The chemical constituents were isolated and purified by multiple chromatographic methods. Their structures were identified on the basis of spectral data and physicochemical properties. Results: Ten compounds were identified as l-phenylalanine (1), thymine (2), inosine (3), guanosine hydrate (4), thymidine (5), 2'-O-methyluridine (6), banegasine (7), adenosine (8), 2'-deoxyadenosine (9), and 5'-deoxy-5'- methylamino-adenosine (10). Conclusion: Compound 3, 5, 6, 9, and 10 are isolated from this plant for the first time.

Objective: To summarize the experience in the treatment of candidiasis albicans. Methods: 95 cases aged 5 months～78 years old with candidiasis albicans were treated by fluconazole and polyactin A etc, the Candida albicans were examined by smear examination.Results: The rate of cure was 35.79 %, that of improvement was 57.89%, the clearance rate of Candida albicans was 80.59%.Conclusion: The Cadida albicans is opportunistic pathogen. Fluconazole is effective in the treatment of candidiasis albicans.

The establishment of induced pluripotent stem (iPS) cells is considered as one of the most important progresses in science and technology nowadays. In recent years, the iPS cells have been used in the construction of cellular model for hereditary heart disease, and the successful treatment in animal model of myocardial infarction, which brings a bright future for exploring the pathogenesis and therapy of hereditary heart disease.
