Therefore, it might be premature to attribute the significant association between type 2 14alpha-hydroxy-Sprengerinin-C diabetes and incident RA to the confounding effect of obesity without further investigation. In conclusion, this large nationwide, population-based, casecontrol study suggested that female patients with type 2 diabetes had an increased risk of developing RA. Although our findings are consistent with the hypothesis that chronic inflammation seen in patients with type 2 diabetes could contribute to the development of RA, further investigation with adjustments for possible confounders is needed before conclusions can be drawn. Nevertheless, given the high and increasing prevalence of type 2 diabetes in Taiwanese and other Asian populations, it is important to understand the effects of type 2 diabetes on the development of RA, particularly in young females. With the advent of wireless technology, there has been a massive increase of electromagnetic radiation exposure to human beings from microwaves to radio waves and other invisible radiation. It has been known that certain intensities of microwave radiation, especially high power microwave, could damage multiple organs, including heart. However, the prevention and treatment of HPM-caused cardiovascular injury remains elusive. In Loganin recent years, the favorable preclinical results have been obtained with some natural compounds from traditional Chinese medicine. Towards that end, there is an urgent need to gain insights into the molecular basis of their effects and develop novel therapies for microwave-radiation�Crelated myocardial injury. In this study, we focused on “Kang Fu Ling”, a compound isolated from Chinese medicine astragalus, red peony, salvia, ophelia, and wolfberry. By using a rat microwave radiation model, we showed that KFL has myocardial protective effects by electrophysiology testing and histological analysis. Further investigation of molecular mechanisms by which pathogenesis is prevented by KFL revealed prevention of mitochondrial dysfunction may be the key event involved in KFL’s myocardial protection effects. The HPM provokes acute myocardial damages of structure and function in lab animals. It has been shown that, when rats were treated with HPM radiation at 100 mW/cm2 for 6 minutes, disappearance and rupture of filaments, together with mitochondrial swelling and cavitation could been observed at 1 and 7 days after radiation. For macaques, with radiation at 11 mW/cm2, their heart rates were reduced immediately after radiation, and the amplitudes of R and T waves were reduced significantly at 1 day after radiation. In the present study, we observed reduced heart rates, a J point shift, swelling and wave-like arrangement of myocytes, and mitochondrial swelling and rupture in rats at 7 days after HPM radiation. These observations indicate that changes in myocardial electrophysiology and structure are associated with myocardial injury, although the specific pathways involved in the pathogenesis of microwave-radiation�Cinduced myocardial injury are unknown. Mitochondria are extremely important organelles in myocytes, accounting for 40�C60% of the cell volume. The mPTP multiprotein complex in the mitochondrial membrane is a key component in mitochondrial signal transduction. Excessive mPTP opening leads to a reduction in the mitochondrial membrane potential and is
associated with numerous heart diseases. Under normal physiological condition, mPTPs are closed.
