Objective. To assess the short-term efficacy and safety of two kinds of Traditional Chinese herbal patches, Fufang Nanxing Zhitong Gao (FNZG) and Shangshi Jietong Gao (SJG), for painful knee osteoarthritis (OA). Methods. Patients were randomly enrolled in a double-blind, placebo-controlled study to receive FNZG (n = 60), SJG (n = 60), or placebo patch (n = 30) for 7 days. Outcome measures included visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Traditional Chinese Medicine Syndrome Questionnaire (TCMSQ) subscale. Results. Although there was no significant difference among, three groups in short-term pain management, patients receiving FNZG got significant improvement in symptom of fear of coldness as compared with placebo patch (P = 0.029). The most common local adverse events of rash, itching, erythema, and slightly damaged skin were observed in 7% of participants. Conclusions. FNZG may be a useful treatment for symptom of knee OA and merits long-term study in broader populations.
Aims: The purpose of this study was to investigate how Osthole affects glioma cell proliferation, apoptosis, invasion and migration. Methods: Rat glioma cells were treated with different concentrations of Osthole (0 µM, 25 µM, 50 µM, and 100 µM). Cell proliferation was assessed by measuring PCNA expression and CCK8 assay at different time points. Apoptosis was evaluated by measuring the expression of pro-apoptotic protein including Bax, Bcl2, PARP, and cleaved Caspase3, and of anti-apoptotic protein Survivin. Cell migration and invasion were assessed using different methods. Signaling pathways such as PI3K/Akt and MAPK, which are involved in the development of glioma cells, were also investigated in this study. Results: Treatment with Osthole markedly inhibits glioma cell proliferation, as assessed by western blot with the PCNA antibody. Osthole also induces cell apoptosis by upregulating the expression of pro-apoptotic proteins, and by reducing the expression of anti-apoptotic factors. Moreover, C6 cell migration and invasion were efficiently inhibited in groups treated with Osthole, compared to the control group. Additionally, inhibition of PI3K/Akt and MAPK signaling pathway was also observed in C6 cells treated with Osthole. Conclusions: Our findings showed an anti-cancer effect of Osthole on glioma cells, including the proliferation inhibition, apoptosis induction, and migration/invasion inhibition. Further investigation in C6 glioma cells implicated the role of Osthole in essential pathways controlling glioma cell progression. Taken together, our data suggested that Osthole may have a potential application in glioma therapy.
Objective. The aim of this study is to systematically evaluate the evidence whether traditional Chinese herbal patches (TCHPs) for osteoarthritis (OA) are effective and safe and analyze their medication patterns. Methods. A systematic literature search was performed using all the possible Medical Subject Headings (MeSH) and keywords from January 1979 to July 2013. Both randomized controlled trials (RCTs) and observational studies were included. Estimated effects were analyzed using mean difference (MD) or relative risk (RR) with 95% confidence intervals (CI) and meta-analysis. Results. 86 kinds of TCHPs were identified. RCTs and controlled clinical trials (CCTs) which were mostly of low quality favored TCHPs for local pain and dysfunction relief. TCHPs, compared with diclofenac ointment, had significant effects on global effectiveness rate (RR = 0.50; 95% CI (0.29, 0.87)). Components of formulae were mainly based on the compounds “Xiao Huo Luo Dan” (Minor collateral-freeing pill) and “Du Huo Ji Sheng Tang” (Angelicae Pubescentis and Loranthi decoction). Ten kinds of adverse events (AEs), mainly consisting of itching and/or local skin rashes, were identified after 3-4 weeks of follow-up. Conclusions. TCHPs have certain evidence in improving global effectiveness rate for OA; however, more rigorous studies are warranted to support their use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
