RÉSUMÉ
Since the significant public health hazard of Hepatitis B virus (HBV) infection and obvious drug resistance and dose-dependent side effects for common antiviral agents (e.g., interferon α, lamivudine, and adefovir), continuous development of agents to treat HBV infection is urgently needed. Traditional Chinese medicine (TCM) is an established segment of the health care system in China. Currently, it is widely used for chronic hepatitis B (CHB) in China and many parts of the world. Over a long period of time in clinical practice and in basic research progress, the effectiveness and beneficial contribution of TCM on CHB have been gradually known and confirmed. Based upon our review of related papers and because of our prior knowledge and experience, we have selected some Chinese medicines, including Chinese herbal formulas (e.g., Xiao-Chai-Hu-Tang, Xiao-Yao-San, and Long-Dan-Xie-Gan-Tang), single herbs (e.g., Phyllanthus niruri, Radix astragali, Polygonum cuspidatum, Rheum palmatum, and Salvia miltiorrhiza) and related active compounds (e.g., wogonin, artesunate, saikosaponin, astragaloside IV, and chrysophanol 8-O-beta-Dglucoside) and Chinese medicine preparations (e.g., silymarin, silibinin, kushenin, and cinobufacini), which seem effective and worthy of additional and indepth study in treating CHB, and we have given them a brief review. We conclude that these Chinese herbal medicines exhibit significant anti-HBV activities with improved liver function, and enhanced HBeAg and HBsAg sero-conversion rates as well as HBV DNA clearance rates in HepG2 2.2.15 cells, DHBV models, or patients with CHB. We hope this review will contribute to an understanding of TCM and related active compounds as an effective treatment for CHB and provide useful information for the development of more effective antiviral drugs.

Japan-China Joint Medical Workshop (2012) on standardization of perioperative management on hepato-biliary-pancreatic surgery was held by the Center for Medical Standards Research, IRCA-BSSA Group in Japan on April 15-16, 2012. Experts in the fields of surgery, anesthesia, pharmacy, and public health from 21 health institutions from Japan and China presented their research achievements and shared their medical experience of perioperative management on hepato-biliary-pancreatic surgery, which should facilitate building of guidelines for hepatocellular carcinoma and be expected to promote standardized management of liver cancer in Asia.

Gastrointestinal cancer is a great threat to human health in Japan. Conventional anticancer therapies including surgery, radiation, and chemotherapy are the main strategies and play important roles in curing this disease or extending the life of patients with these cancers. On the other hand, patients undergo great suffering induced by these treatments. Kampo, the Japanese traditional medicine, has been used in clinics to reduce side effects and to improve the quality of life of gastrointestinal cancer patients in Japan. In order to testify to the efficacy and safety of these Kampo medicines and to clarify the underlying mechanisms, a number of clinical and basic studies were implemented in the past several decades. These studies suggested the benefits of Kampo medicine as an adjuvant to conventional anti-cancer therapies in treating gastrointestinal cancer. Since the safety and efficacy as well as quality control of traditional medicine have long been focused worldwide, the development course of Kampo medicine may provide reference to other countries in the world.

This 8-week, randomized, placebo-controlled, double-blind clinical study investigated the short-term effectiveness and safety of the traditional Chinese medicine, Ningdong (ND) granule in paediatric subjects (aged 7 - 18 years) with Tourette's disorder (TD). Subjects received either 1 g/kg per day ND granule (n = 33) or placebo (n = 31) and tics were measured at baseline and after 4 and 8 weeks of treatment. Body mass index, electrocardiogram and laboratory measures were recorded at baseline and at week 8. After 8 weeks of treatment with ND granule, subjects exhibited a 41.39% reduction in the total tic score while the placebo group showed a 10.79% decrease. Regarding side-effects, two subjects reported loss of appetite and one experienced constipation in the ND granule group. There were no significant changes in laboratory and physical examinations. These results suggest that ND granule is both effective and safe, and may be a good candidate for the treatment of patients with TD.

AIMS: The aim of the study was to isolate the endophytic fungi from Acer ginnala and screen isolates rich in gallic acid. METHODS AND RESULTS: After epiphytic sterilization, 145 fungal endophytes were isolated from the stem, annual twig and seed of Acer ginnala. The endophytes were grouped into ten different taxa, Phomopsis sp., Neurospora sp., Phoma sp., Epicoccum sp., Penicillium sp., Alternaria sp., Fusarium sp., Trichoderma sp., Cladosporium sp. and a species of Pleosporales Incertae Sedis, by their morphological traits and ITS-rDNA sequence analysis. The content and yield of gallic acid of 141 isolates were determined by HPLC. On average, the species of Pleosporales Incertae Sedis had the highest content and yield of gallic acid (13.28 mg g(-1) DW; 119.62 mg l(-1)), while Alternaria sp. had the lowest. CONCLUSIONS: Of 141 fungal endophytes from A. ginnala, Phomopsis sp. isolate SX10 showed both the highest content and the highest yield of gallic acid (29.25 mg g(-1) DW; 200.47 mg l(-1)). SIGNIFICANCE AND IMPACT OF THE STUDY: Endophytic fungi isolated from A. ginnala may be used as potential producers of gallic acid and other compounds with biological activities, or functioned as elicitors to produce natural compounds.

Cinobufacini, a water-soluble preparation of Chinese medicine, is extracted from the skin of Bufo bufo gargarizans Cantor. The present study sought to investigate the effects of Cinobufacini on apoptosis of the hepatocellular carcinoma cell line BEL-7402. Cell viability was measured by methyl thiazolyl tetrazolium assay. Cell morphology was observed by Hoechst 33258 staining. Western blotting analysis was used to detect Bax and Bcl-2 expression. Results indicated that Cinobufacini inhibited the proliferation of BEL-7402 cells in a dose and time-dependent manner. Marked morphological changes indicative of apoptosis were observed after treatment with different concentrations of Cinobufacini. Western blot analysis showed that Bcl-2 expression was down-regulated while Bax expression was upregulated. Thus, Cinobufacini may have a significantãapoptosis-inducing effect on BEL-7402 cells, and this could prove useful for further anti-cancer research.
