The components of the glass sample were 25TiO2-27BaCO3-8Ba (NO3)2-5ZnO2-10CaCO3-5H3BO3-10SiO2-7water glass-3Er2O3 ( % , mass fraction) . The emission spectra of titanium barium glass matrix and the titanium barium glass microsphere under 514 nm excitation were measured with micro-Raman spectrometer. Whispering gallery modes in the emission spectra from a 31μm glass microsphere were observed. Many regularly spaced, sharp peaks appeared in the emission spectra of the Er2O3-doped glass microsphere. The wavelength separation between the two adjacent peaks is 1.92 nm for the 31μm microsphere. According to the Lorenz-Mie formula, the calculated value of the wavelength separation between the two adjacent peaks is 1.95 nm. The observed resonances could be assigned by using the well-known Lorenz-Mie formula.展开更多

The 2 groups before and after treatment collected fasting peripheral venous blood, the determination of Ca, P and alkaline phosphatase by colorimetric method (ALP), Ca, P product calculation (Ca×P), to detect the level of iPTH before and after treatment by ELISA method;TY-6858-HI type ultrasound instrument, measuring length, width and thickness of the parathyroid glands, and calculate the parathyroid gland volume.Results:in the observation group after treatment, Ca, Ca×P increased degree, P, ALP, iPTH lower than the control group, the size of the parathyroid gland was better than the control group.Conclusion:calcitriol, cinacalcet combined intervention therapy has good clinical effect in patients with MHD SHPT, Ca, P can effectively improve the metabolism, reduce the level of iPTH, reduce the parathyroid gland volume is worthy of promotion.展开更多
