Chinese herbal medicine for patients with mild to moderate Alzheimer disease based on syndrome differentiation: a randomized controlled trial / 中西医结合学报

Alzheimer disease (AD) is a chronic neurodegenerative disease that is characterized by its gradual progression. At present, the cause and mechanism of AD are yet unclear, and there is no effective therapy for treating it. With development of global aging, the prevalence rate of AD is increasing. The life quality of elderly people is affected severely by AD that is ultimately life-threatening. Recently, study on treating AD with traditional Chinese medicine (TCM) has deepened.

The Monolayer Culturing of The Neural Stem Cell Clone and Its Qualification / 生物化学与生物物理进展

The primary neural stem cells were isolated from SD rat and formed the neuropheres, the neuropheres were passaged and planted on the dish coated with 0.1% gelatin, the colony was picked up under the microscope, then dispersed and cultured, to obtain the clone proliferated from one cell, passaging and picking up the cells 5～6 times at least. The NSC and its differentiated cells were identified with the marker genes respectively. The results showed that the neural stem cells were isolated from the SD rat embryos and the real clone were obtained by picking up the cells again and again, and then cultured in the form of monolayer. The marker genes of the neural stem cells and its differentiated cells could be detected at last. It will provide the rat model the resource of the cells for the treatment and the basic research for the morphology standard.
