There has been a lot of controversy in the scientific research of Chinese medicine. Many experts pointed out that the scientific research of Chinese medicine is becoming more and more westernized. It is not suitable for the development of Chinese medicine to study Chinese medicine with the research methods of western medicine.

The director of the Institute of Spinal Diseases of Shanghai University of Traditional Chinese Medicine (Longhua Hospital) is Professor Wang Yongjun, a well-known orthopedic expert in traditional Chinese medicine, and the honorary director is Professor Shi Qi, a well-known traditional Chinese medicine expert. Focus on the study of traditional Chinese medicine in the prevention and treatment of major and complex diseases such as cervical spondylotic myelopathy, osteoporosis, and spinal tumors.

The research institute purchased a Tissuelyser-48 automatic sample rapid grinder from Shanghai Jingxin Technology to crush and grind the researched spine bone, leg bone and other tissues. So that the grinding bone tissue has found a simple and efficient method of crushing.

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.
