Rupture of aortic sinus aneurysms is a rare cardiac malformation that is commonly observed in the right coronary sinus but is rarely observed in the noncoronary sinus. Here, we report a case of aneurysm of the aortic sinus that ruptured into the left ventricular outflow tract and was diagnosed with left ventricular opacification. Left heart echocardiography can clearly demonstrate the structure of the heart and is one of the important diagnostic methods for diagnosing ruptured aortic sinus aneurysms.

Article Synopsis
- Cadmium is a long-lasting pollutant linked to higher rates of cardiovascular diseases, and its impact on dyslipidemia among exposed workers in China is being evaluated.
- A study involving 1,489 workers from cadmium smelting factories assessed blood cadmium levels and lipid profiles, revealing a 66.3% prevalence of dyslipidemia, with higher cadmium concentrations correlating with worsened lipid profiles.
- Results showed that as blood cadmium levels increased, dyslipidemia prevalence also rose significantly, indicating a potential relationship between occupational cadmium exposure and cardiovascular risk factors.
Carney complex is a syndrome characterized by skin pigmentation abnormalities, myxomas, endocrine tumors/overactivity, and schwannomas. It is caused by a mutation in the PRKAR1A gene that encodes the enzyme protein kinase A regulatory subunit type 1 alpha. A 23-year old male was diagnosed with Carney complex on the basis of spotty skin lentigines on his face and lips, multiple thyroid neoplasms, a right ventricular myxoma, and bilateral testicular tumors.

Objective: To study the change of heat shock protein (HSP)70 expression after exposure to occupational microwave in rats hippocampus, and explore the role of HSP70 in the mechanism of bio-effect of microwave irradiation.
Methods: The animal model was established by whole body exposures in 90, 5 W/cm(2) microwave irradiation field for 20 min in rats. Changes of the mRNA of hsp70 expressions in rat hippocampus at different time were studied by RT-PCR, and the protein change by Western blot.
