Bear bile has been used in Traditional Chinese Medicine (TCM) for thousands of years. Modern investigations showed that it has a wide range of pharmacological actions with little toxicological side effect and the pure compounds have been used for curing hepatic and biliary disorders for decades. However, extensive consumption of bear bile made bears endangered species. In the 1980's, bear farming was established in China to extract bear bile from living bears with "Freedripping Fistula Technique". Bear farming is extremely inhumane and many bears died of illness such as chronic infections and liver cancer. Efforts are now given by non-governmental organizations, mass media and Chinese government to end bear farming ultimately. At the same time, systematic research has to be done to find an alternative for bear bile. In this review, we focused on the literature, laboratory and clinical results related to bear bile and its substitutes or alternative in English and Chinese databases. We examined the substitutes or alternative of bear bile from three aspects: pure compounds derived from bear bile, biles from other animals and herbs from TCM. We then discussed the strategy for stopping the trading of bear bile and issues of bear bile related to potential alternative candidates, existing problems in alternative research and work to be done in the future.

BackgroundVancomycin (VCM) treatment outcomes depend on the characteristics of the patient, and it is well known that hypoalbuminemia is a risk factor for poor treatment outcomes, as reported in a previous study. However, the reason that severe hypoalbuminemia has an influence on the treatment outcome of VCM remains unknown.ObjectiveTo elucidate the association between severe hypoalbuminemia and VCM treatment outcomes, we examined pharmacokinetic/pharmacodynamic (PK/PD) parameters in elderly patients with severe hypoalbuminemia.MethodsWe conducted a retrospective observational study of 94 patients with methicillin-resistant Staphylococcus aureus (MRSA) hospital-acquired pneumonia who had been treated with VCM between January 2006 and December 2012. The 94 patients were divided into severe hypoalbuminemia and non-severe hypoalbuminemia groups. The PK/PD parameters and treatment outcomes of VCM were compared between the two groups.ResultsThe half-life of VCM in the severe hypoalbuminemia group was significantly longer than in the non-severe hypoalbuminemia group (33.2 + 5.4 vs 24.9 + 1.6; P = 0.049). Area under the concentration curve (AUC)/minimum inhibitory concentration (MIC) values of 250–450 and >450 μg × h/mL were significantly associated with 28-day mortality in the severe hypoalbuminemia group (P < 0.001), whereas AUC/MIC values of <250 μg × h/mL were not associated. We also detected a significant difference in the increased percentage of nephrotoxicity in the severe hypoalbuminemia group (6 of 23 patients [26%]) compared with the non-severe hypoalbuminemia group (6 of 71 patients [8%]; P < 0.001).ConclusionThese findings indicate that severe hypoalbuminemia influences the half-life of VCM and treatment outcomes in elderly patients (≥75 years of age). To establish a more effective and safer treatment protocol, the issue of malnutrition in elderly patients needs to be addressed and improved.

Our results indicate that HLJDD has potential in blocking HCC progression with involvement of eEF2 inhibition.

The pivotal role of cancer stem cells (CSCs) in the initiation and progression of malignancies has been rigorously validated, and the specific methods for identifying and isolating the CSCs from the parental cancer population have also been rapidly developed in recent years. This review aims to provide an overview of recent research progress of Chinese medicines (CMs) and their active compounds in inhibiting tumor progression by targeting CSCs. A great deal of CMs and their active compounds, such as Antrodia camphorate, berberine, resveratrol, and curcumin have been shown to regress CSCs, in terms of reversing drug resistance, inducing cell death and inhibiting cell proliferation as well as metastasis. Furthermore, one of the active compounds in coptis, berbamine may inhibit tumor progression by modulating microRNAs to regulate CSCs. The underlying molecular mechanisms and related signaling pathways involved in these processes were also discussed and concluded in this paper. Overall, the use of CMs and their active compounds may be a promising therapeutic strategy to eradicate cancer by targeting CSCs. However, further studies are needed to clarify the potential of clinical application of CMs and their active compounds as complementary and alternative therapy in this field.

Liver fibrosis is a condition of abnormal proliferation of connective tissue due to various types of chronic liver injury often caused by viral infection and chemicals. Effective therapies against liver fibrosis are still limited. In this review, we focus on research on Chinese medicines against liver fibrosis in three categories, namely pure compounds, composite formulae and combination treatment using single compounds with composite formulae or conventional medicines. Action mechanisms of the anti-fibrosis Chinese medicines, clinical application, herbal adverse events and quality control are also reviewed. Evidence indicates that some Chinese medicines are clinically effective on liver fibrosis. Strict quality control such as research to identify and monitor the manufacturing of Chinese medicines enables reliable pharmacological, clinical and in-depth mechanism studies. Further experiments and clinical trials should be carried out on the platforms that conform to international standards.

Aim: To analyze the impact of clinical medication reviews (CMR) on reducing unplanned hospitalizations owing to polypharmacy among older adults using an intervention.Methods: Our meta-analysis complied with PRISMA guidelines. The literature review comprised a search for articles published between January 1972 and March 2017 on MEDLINE and Google Scholar. We identified randomized controlled trials focusing on CMR that evaluated unplanned hospitalization and re-hospitalization among older adults as a primary outcome. The keywords used were "CMR" or "medication review" in their titles, and the phrases "elderly" or "older adults" or "geriatric" and "polypharmacy." The randomized controlled trials selected were divided according to the three types of CMR to analyze the characteristics of each review. Results:We included nine randomized controlled trials that examined the impact of CMR of polypharmacy in older patients. Five trials corresponded to CMR type I (prescription only review) or II (adherence review), whereas four corresponded to type III (comprehensive clinical evaluation for disease management). Type I/II increased the number of unplanned hospitalizations (RR 1.22, 95% CI 1.07-1.38, P = 0.002), whereas type III decreased hospital admissions (RR 0.86, 95% CI 0.79-0.95, P = 0.001). Conclusions:The present findings show the need for an intervention standardization for CMR, particularly for type III in older adults with polypharmacy, to decrease hospitalizations.

ABSTRACT-We investigated the effect of acteoside in comparison with that of cyclosporin A on leukocyte accumulation in the glomeruli of rats with crescentic-type anti-glomerular basement membrane (GBM) nephritis. Acteoside given p.o. at a dose of 30 mg/kg once a day for 15 consecutive days after treatment with anti-GBM serum markedly suppressed the urinary protein as well as glomerular histological changes. Acteoside given p.o. for 5 or 15 consecutive days markedly suppressed the accumulation of total leukocytes, ED-1-positive cells (monocytes/macrophages), CD4-positive cells, CD8-positive cells, interleukin-2-recep tor-positive cells (activated T cells) and la-positive cells in the glomeruli. These effects of cyclosporin A (20 mg/kg/day, p.o.) were also as potent as those of acteoside (30 mg/kg/day, p.o.). Cyclosporin A also strong ly suppressed the elevation of plasma antibody level against rabbit f-globulin. However, in this dose, acteoside did not significantly suppress the antibody formation. It can be concluded from these results that acteoside may exert its antinephritic action by suppressing the accumulation of leukocytes in the glomeruli.
