Shufeng Jiedu Capsule and its active ingredients induce apoptosis, inhibit migration and invasion, and enhances doxorubicin therapeutic efficacy in hepatocellular carcinoma.

BACKGROUND: Shufeng Jiedu Capsule (SFJDC), a traditional Chinese medicine, has been used widely as antiviral, antibacterial, antitumor, and anti-inflammatory drugs. Previous studies indicated that some active ingredients of Shufeng Jiedu Capsule, such as resveratrol and quercetin, could suppress hepatocellular carcinoma (HCC) cells through various signaling pathways. However, anti-HCC activity of SFJDC as a complementary medicine remains unexplored. Here, we use a combination of Shufeng Jiedu Capsule and doxorubicin to treat HCC cells and investigated the effects and mechanisms of SFJDC and its ingredientsin vitro. METHODS: In this study, two HCC cell lines, HepG2 and HepG2.2.15, were employed and all cells were separated into seven groups: doxorubicin group, SFJDC group, combination of doxorubicin and SFJDC group, resveratrol group, quercetin group, resveratrol and quercetin group, and control group. Through this research, the cellular functional experiments, such as MTT assay, Hoechst 33,258 staining, would healing assay, and transwell assay, were took to observe the effects of those agents on proliferation, apoptosis, migration and invasion of cells. Then, apoptosis and invasion related genes and proteins were detected by real-time PCR and western blot to illuminate the signaling pathways. RESULTS: The combination group induced more significant apoptosis and inhibition of migration and invasion by affecting proteins and mRNA of apoptosis, migration, and invasion related elements, such as Bcl-2, Bax, mTOR, and NF-?B. Furthermore, the research suggested SFJDC, as a mixture of a number of ingredients, had stronger activities than particular component or simple mixture of a few components. CONCLUSIONS: SFJDC and its active ingredients could play a role as complementary medicine to increase antitumor effect of doxorubicin by targeting mitochondrial, Akt/mTOR, and NF-?B signaling pathways.

Combination of Cinobufacini and Doxorubicin Increases Apoptosis of Hepatocellular Carcinoma Cells through the Fas- and Mitochondria-Mediated Pathways.

Cinobufacini, a traditional Chinese medicine, has been used widely for cancer treatment, such as hepatocellular carcinoma (HCC), sarcoma, and leukemia. Previous studies done by our lab indicated that cinobufacini could suppress HCC cells through mitochondria-mediated and Fas-mediated apoptotic pathways. Here, we use a combination of cinobufacini and doxorubicin to inhibit the growth of HCC cells. The combination group induced more significant apoptosis by affecting proteins and RNA of apoptosis-related elements, such as Bcl-2, Bax, Bid, and cytochrome c. Furthermore, cinobufacini, as a mixture of a number of components, had stronger apoptosis-inducing activity than particular individual components or a simple mixture of a few components. Overall, these results suggested that the combination of cinobufacini and doxorubicin may provide a new strategy for inhibiting the proliferation of HCC cells.

Researchers of chronic obstructive pulmonary disease gathered at the 2017 Japan-China Joint Medical Workshop on Aging and Health.

As the number of elderly and the size of the total population increase, population aging will become a major problem because of an increase in diseases associated with aging, such as chronic obstructive pulmonary disease (COPD). The 2017 Japan-China Joint Medical Workshop on Aging and Health was held at The University of Tokyo on December 2, 2017 with a focus on management of COPD. More than 50 experts in the fields of respiratory medicine, emergency medicine, traditional Chinese medicine, and Kampo (traditional Japanese medicine) from Japan and China presented the results of their research and shared their experiences treating COPD from different perspectives. Guidelines for diagnosis and management of COPD in different countries were described at the workshop, and advances in recent research into the treatment of COPD with Kampo and traditional Chinese medicine were fully discussed. The results of the workshop should help to improve GOLD guidelines and they should greatly help to optimize COPD treatment.

Advance in studies on traditional Chinese medicines to treat infection with the hepatitis B virus and hepatitis C virus.

Traditional Chinese medicine (TCM), as a type of complementary and alternative medicine (CAM), is a sophisticated and time-honored form of healthcare in China. Many TCMs are widely used to treat hepatitis B and hepatitis C in countries like China, Japan, and South Korea. Since conventional clinical preparations like interferon-α cause obvious dose-dependent adverse reactions and drug resistance, TCMs and related bioactive compounds have garnered increasing attention from physicians and medical researchers. Thus far, a number of TCMs and compounds have been used to inhibit the hepatitis B virus (HBV) or hepatitis C virus (HCV) in vitro, in vivo, and even in clinical trials. The current review summarizes TCMs and related compounds that have been used to inhibit HBV or HCV. Most of these medicines are derived from herbs. HepG2.2.15 cells have been used to study HBV in vitro and Huh7.5 cells have been similarly used to study HCV. Ducks have been used to study the anti-HBV effect of new medication in vivo, but there are few animal models for anti-HCV research at the present time. Thus far, a number of preclinical studies have been conducted but few clinical trials have been conducted. In addition, a few chemically modified compounds have displayed greater efficacy than natural products. However, advances in TCM research are hampered by mechanisms of action of many bioactive compounds that have yet to be identified. In short, TCMs and related active compounds are a CAM that could be used to treat HBV and HCV infections.
