RESUMO
Herb pair， a common form of compounding in Chinese medicinal prescriptions， reflects the experience of pharmacists in clinical medication in the past. It is characterized by simple composition while has the basic characteristics of Chinese medicine compounding. The combination of two medicinal herbs can enhance effect or reduce toxicity. Coptidis Rhizoma （CR） has the effects of clearing heat， drying dampness， purging fire， and removing toxin. Euodiae Fructus （EF） is acrid， bitter， and hot-natured， which can not only warm the Yang Qi in spleen and stomach to dissipate cold and relieve pain， but also descend stomach Qi and prevent vomiting. Furthermore， it can warm the liver and kidney. CR and EF form a typical cold-heat herb pair， which oppose and yet also complement each other. Specifically， their cold and heat natures interact with each other to clear liver fire， harmonize stomach for descending adverse Qi， relieve depression， and dissipate mass. CR clears the intestine and stops dysentery， while EF warms the middle and promotes the circulation of Qi. The combination of them can thus clear heat， dry dampness， and relieve pain. Modern pharmacological studies have demonstrated that CR-EF has not only significant efficacy against digestive system diseases but also good anti-cancer， anti-inflammatory， anti-ulcer， and lipid-lowering activities. Therefore， the article summarized the effect enhancement and toxicity reduction of the herb pair at the levels of cellular molecule， isolated organ， and whole animal， and clarified the mechanism of its pharmacological action. It will provide a theoretical basis for further development and clinical use of the herb pair.
RESUMO
As the main active ingredient of the orchidaceous herb Bletilla striata, B. striata polysaccharide(BSP) has pharmacological activities such as promoting coagulation, anti-inflammation, anti-oxidation, promoting wound healing, anti-tumor, and immunomodulation, and is biodegradable and non-toxic. Additionally, it has the material properties of suspension thickening, film-forming adhesion, coating and solubilizing, targeting and slow releasing, effect-enhancing and toxicity-reducing, etc., playing the role of unification of medicines and excipients. Therefore, BSP has a wide application prospect in the fields of drug delivery system and trauma repair. This paper reviews the research progress of BSP application in new drug delivery systems and biomaterials based on the related li-terature in recent years, with the aim of providing reference for the further research and application of BSP.

The incidence of prostate cancer is increasing, and inevitably progresses to castration-resistant prostate cancer. Although the treatment is constantly updated, the prognosis is still not optimistic. Because of its unique advantages of effect-enhancing and toxicity-reducing, improving quality of life, and prolonging survival time, Chinese medicine has occupied a very important position in the treatment of castration resistant prostate cancer. This article summarizes the clinical and basic research of traditional Chinese medicine in the treatment of castration-resistant prostate cancer, and provides reference for clinical treatment and basic research.
RESUMO
The incidence of prostate cancer in China is increasing visibly, and bone metastasis is easy to occur in the late stage of that, which seriously affects the quality of life of the patients. Modern medicine has made rapid progress in the treatment of chemotherapy and radiotherapy, hormone therapy and radionuclide therapy for bone metastasis of prostate cancer, accompanied by some various side effects yet. The synergistic actions of effect-enhancing and toxicity-reducing, multi-targets and multi-effects from Chinese medicinal materials combined with chemical medicines have attracted more and more attention in the medical field, which display some advantages in improving the life quality of patients, relieving the clinical symptoms and prolonging the survival period. As a special medical means in China, the unique theory and drug use of traditional Chinese medicine have brought new dawn to the treatment of bone metastasis of prostate cancer.
