Tanshinone I (Tanshinone-1), a major active principle of the traditional Chinese medicine Salvia miltiorrhiza, possesses excellent anticancer properties, including inhibiting proliferation, angiogenesis and metastasis and overcoming multidrug resistance (MDR). However, its direct anticancer molecular target(s) remain unknown. Here we report that tanshinone-1 and its two new derivatives, S222 and S439, directly inhibit DNA topoisomerase I/II (Top1/2). With significantly improved water solubility, S222 and S439 displayed 12- and 14-times more potent proliferative inhibition than their parent tanshinone-1 in a panel of 15 cancer cell lines...

Alzheimer’s Disease (AD) is a neurodegenerative condition that currently has no known cure. The principles of the expanding field of network medicine (NM) have recently been applied to AD research. The main principle of NM proposes that diseases are much more complicated than one mutation in one gene, and incorporate different genes, connections between genes, and pathways that may include multiple diseases to create full scale disease networks. AD research findings as a result of the application of NM principles have suggested that functional network connectivity, myelination, myeloid cells, and genes and pathways may play an integral role in AD progression, and may be integral to the search for a cure...

Researches on the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine are becoming a hot spot in andrology, but many recent studies of this kind have failed to explain the connotation of integrated traditional Chinese and Western medicine in andrology. Related existing problems include repeated researches into the same indexes of action mechanisms of different therapeutic principles of traditional Chinese medicine (TCM), Chinese herbal compound and special prescriptions, studies focusing on individual diseases but ignoring symptoms, immature syndrome models for studies of mechanisms, and too much attention to uncertain or immature target mechanisms...
