The Shanghai Diabetes Clinic Medical Center of the Department of Endocrinology and Metabolism, Shanghai Sixth People’s Hospital is a comprehensive institution integrating clinical, scientific research, and teaching. It is also the Shanghai Diabetes Research Institute, Shanghai Key Laboratory of Diabetes, National Key Discipline, Key discipline of the Municipal Education Commission.

When studying and analyzing common pathological tissue samples of the endocrine system, such as kidney, pancreatic islets, breast and other diseased tissues, the laboratory uses Shanghai Jingxin Technology Grinding Machine to process samples quickly and efficiently.

There is no significant difference in the concentration and purity of the DNA and RNA extracted from FT after the automatic sample rapid grinder treatment and manual liquid nitrogen grinding treatment of Shanghai Jingxin (pairwise test P>0.05). However, manual grinding has a larger sample loss rate. For samples with low DNA extraction concentration, the automatic grinder can achieve zero sample loss. It has obvious advantages in DNA extraction, and the manual processing process is complicated and easy to cross. Contamination, operation time and other aspects are not as good as Shanghai Jingxin's automatic sample rapid grinder, so the automatic grinder has great advantages for DNA extraction compared to manual grinding.
