Introduction: A giant right ventricular myxoma with simultaneous pulmonary embolism during Transthoracic Echocardiographic examination is rare, hardly been reported in the literature. We present a case of a giant right ventricular myxoma with being separated into pulmonary thrombus simultaneously during process of Transthoracic Echocardiographic examination. Case presentation: An 18-year-old young man performed physical examination before college entrance examination. Transthoracic echocardiography (TTE) showed: a heterogeneous mass was found in the right ventricle. The patient suddenly felt the symptoms of chest pain and dyspnea during a transthoracic ultrasound examination, and TTE demonstrated the mass maybe a myxoma with being separated into pulmonary thrombus simultaneously. Electrocardiogram showed complete right bundle branch block. The young man underwent intracardiac repair immediately and was doing well. Discussion/Conclusion: Although myxoma of the right heart is common, complicating of pulmonary embolism during examination is rare especially. Early diagnosis of right heart myxoma complicated with pulmonary embolism provides an important basis for timely operation, and provides a guarantee for saving the life of patients.

China experienced heavy aerosol pollution in recent years. The aerosol pollution might change surface solar radiation and impact the land carbon cycle in China. Therefore, we combined the MODIS Atmosphere and Land products with process-based model to evaluate the sensitivity of GPP to AOD in different spectral bands under all-sky and cloudless conditions and the effects of current aerosol loadings on GPP at site level. Our results indicated that the radiative effects of aerosols on GPP varied with the vegetation type, which is consistent with other studies. We also found that the radiative effects of aerosols on GPP varied with the spectral bands. Cloud restrains the effects of aerosols on growth of plants. Current aerosol loadings fertilized the growth in two forest growth and slightly impede the growth of grass. The results in this paper could be help to fully understand the influences of aerosol on land carbon cycle.
