    AIM: To understand Baduanjin rehabilitation therapy in mild COVID-19 patients.

    DESIGN: A narrative review.

    METHODS: A literature search for COVID-19 and Baduanjin treatments was conducted on Chinese and English electronic databases: China National Knowledge Infrastructure, Wanfang Data, Embase, PubMed, Scopus, Science Direct, Ebscohost, SPORTDiscus and ProQuest.

    RESULTS: Twelve studies on the Baduanjin rehabilitation for COVID-19 patients have been included. We acknowledged the considerable published research and current clinical practice using Baduanjin for COVID-19 treatment in the following areas: anxiety, depression, insomnia, lung function rehabilitation, immunity and activity endurance.

    CONCLUSION: The use of Baduanjin as adjuvant therapy for COVID-19 patients' rehabilitation is still limited, therefore, more clinical studies are needed to confirm its efficacy.

    Early development of liver cancer is usually asymptomatic. The overall survival rate of patients is relatively low due to late diagnosis, despite hepatocellular carcinoma being a common diagnosis. The high mortality rate of liver cancer was due to its overactivated cellular mitochondrial activities, namely thioredoxin reductase enzymatic activities and its downstream activation of nuclear factor kappa B (NF-κB) signaling pathways for cancer cell migration. Our previous study on this candidate compound on A2780 ovarian cancer cells and MCF-7 breast cancer cells, through modulation of cell-cycle checkpoints and respective targeted apoptosis pathways. The current study used HepG2 hepatocellular carcinoma cell lines as a representative in vitro liver cancer cell model. The half maximal inhibitory concentration (IC50) value was obtained via incubation of PTZ compound for 24 h yield of 37.03 μM, whereby it was three-fold more potent than the standard control tested, cisplatin (109.23 μM). The subsequent application of IC50 dosage of PTZ onto HepG2 cells illustrated a growth-static effect via activation of S-phase cell-cycle checkpoints, immediately followed by regulation of apoptosis. Increased cellular concentration of reactive oxygen species eventually generated oxidative damages on mitochondria, hence resulting in the release of cytochrome c protein and suppression of TrxR enzymatic activity, in conjunction with the suppression on invasion of cancer cells via Matrigel invasion chamber. In conclusion, PTZ was hypothesized to act effectively on mitochondria of HepG2 cells; hence it should proceed into detailed drug targeting mechanism research.
