Cardiovascular disease (CVD) is a significant cause of death worldwide. Because of its major individual differences in genetic background, pathogenesis, and disease progression pattern, the mortality risk rate remains high following conventional Western medicine diagnosis under current guidelines. Traditional Chinese medicine (TCM) has important multi-target, multi-pathway, and multi-layer benefits that can effectively address western medicine deficiencies. It was therefore commonly used in CVD diagnosis. Oxidative stress is also one of the main factors of CVD. Likewise, this main reaction regulator is the nuclear factor erythroid-2-related (Nrf2) factor. When activated, it can be transferred to the nucleus and initiated in the downstream pathway, thus playing an anti-oxidant stress role. As one of the most crucial endogenous protection systems in the body, Nrf2-related / heme oxygenase 1 (Nrf2/HO-1) signaling pathway is Nrf2's most classic approach to playing roles. Recently, various advances have been made to research and explain TCM by manipulating this pathway to treat CVD using modern molecular biology and other approaches. This analysis summarized the relationship between Nrf2/HO-1 signaling route, CVD and TCM. Further, Autodock calculation was also conducted to determine the binding amino acid on this TCM to Nrf2 and HO-1.

Prostate cancer is the most common illness affecting men worldwide. Although much progress has been made in the study of prostate cancer prevention and treatment, less attention has been paid to the molecular mechanism of the disease. The molecular arrangement by which atractylenolide II (ATR II) induces human prostate cancer cytotoxicity was comprehensively examined in the present study. As indicated by the results, ATR II could inhibit prostate cancer cell proliferation and promote DU145 and LNCaP cell apoptosis through induced G2/M cell cycle arrest. The cell apoptosis process induced by ATR II in both DU145 and LNCaP cells was associated with its ability to inhibit androgen receptor (AR) with overexpression of protein inhibitor of activated STAT-1 (PIAS1) and the repression of Janus kinase (Jak2) signaling pathways. The data from the present study demonstrated the antitumor effects and the potential pharmacological application of ATR II as an efficient drug for prostate cancer treatment.
Prostate cancer is a serious affliction worldwide. Although much progress has been made in the study of prostate cancer prevention and treatment, less attention has been paid to the molecular mechanism of the disease. The molecular arrangement by which Schisandrin B (Sch B) induces human prostate cancer cytotoxicity was comprehensively examined in the present study. As indicated by the results of flow cytometric and western blot analysis, Sch B could inhibit prostate cancer cell proliferation and promote DU145 and LNCaP cell apoptosis and S‑phase cell arrest. Moreover, real‑time PCR, flow cytometry and western blot result revealed that the cell apoptosis process induced by Sch B in LNCaP cells was associated with its capacity to generate oxidative stress, its inhibition of androgen receptor and the phosphorylation of PI3K/AKT and STA3/JAK2. The data from the present study demonstrated the antitumor effects and the potential pharmacological application of Sch B as an efficient drug for prostate cancer.
