Nephrocalcinosis is often accompanied by kidney stone disease. In recent years, more and more nephrocalcinosis has been found to be caused by a monogenic disease, and its pathogenesis has not been fully elucidated. With the development of molecular genetics, more than 30 genes have been found to be the causative genes of nephrocalcinosis. At the same time, with the widespread development of genetic testing technology, more patients have received early diagnosis and timely intervention. This article reviews the clinical and basic research progress of monogenic nephrocalcinosis.

Objective: To determine the contents of cinobufagin and resibufogenin in Qianglijiuxin Dripping Pills. Methods: The HPLC method was used at Kromasil C 18 column of 250mm?4.6mm, 5?m, 0.5% Dipotassium Hydrogen Phosphate Acetonitrile (50∶50) as the mobile phase, 1.0mL/min as the flow rate at detection wavelength of 296nm. Results: For cinobufagin, the linear range was 0.67?g~4.7?g and the average recovery rate was 97.78% with RSD=1.2%. For resibufogenin, the linear range was 0.33?g~2.3?g and the average recovery was rate 99.61% with RSD=2.0%.Conclusion: The method can be applied to content determination of cinobafagin and Resibufogenin in Qianglijiuxin Dripping pills.
