Anxiety and depression are common among patients with cancer, and are often treated with psychological interventions including mindfulness-based therapy.The aim of the study was to perform a meta-analysis of the effectiveness of mindfulness-based interventions for improving anxiety and depression in patients with cancer.Medline, the Cochrane Library, EMBASE, and Google Scholar were searched. The randomized controlled trials designed for patients diagnosed with cancer were included. Mindfulness-based interventions were provided.The outcomes assessed were the changes in anxiety and depression scores from before to after the intervention. The treatment response was determined by calculating the standardized mean difference (SMD) for individual studies and for pooled study results. Subgroup analyses by cancer type, type of therapy, and length of follow-up were performed.Seven studies, involving 469 participants who received mindfulness-based interventions and 419 participants in a control group, were included in the meta-analysis. Mindfulness-based stress reduction and art therapy were the most common interventions (5/7 studies). All studies reported anxiety and depression scores. The pooled SMD of the change in anxiety significantly favored mindfulness-based therapy over control treatment (-0.75, 95% confidence interval -1.28, -0.22, P = 0.005). Likewise, the pooled SMD of the change in depression also significantly favored mindfulness-based therapy over control (-0.90, 95% confidence interval -1.53, -0.26, P = 0.006). During the length of follow-ups less than 12 weeks, mindfulness-based therapy significantly improved anxiety for follow-up ≤12 weeks after the start of therapy, but not >12 weeks after the start of therapy.There was a lack of consistency between the studies in the type of mindfulness-based/control intervention implemented. Patients had different forms of cancer. Subgroup analyses included a relatively small number of studies and did not account for factors such as the severity of anxiety and/or depression, the time since diagnosis, and cancer stage.Mindfulness-based interventions effectively relieved anxiety and depression among patients with cancer. However, additional research is still warranted to determine how long the beneficial effects of mindfulness-based therapy persist.

<bold>Background: </bold>Tong Luo Hua Shi (TLHS) is a new formulation of the traditional Tibetan medicine Wu-wei-gan-lu that has been used for the treatment of rheumatoid arthritis (RA) for hundreds of years in China. This study aimed to evaluate the efficacy and safety of TLHS in patients with RA.<bold>Methods: </bold>This was a randomized, double-blind, placebo-controlled, dose-finding study performed in patients with active RA from five medical centers. Patients received three doses (4.8, 3.6, or 2.4 g/day po) of TLHS or placebo (tid po) for 8 weeks. Blood sampling, physical examination, and assessment of the American College of Rheumatology (ACR) 20 % improvement (ACR20) criteria were performed before and every 2 weeks after starting treatment. The primary endpoint was the ACR20. The secondary endpoints included safety.<bold>Results: </bold>A total of 240 participants were screened and 236 patients were randomized (n = 59/group); 20 dropped out. After 8 weeks, ACR20 improvements in the TLHS 4.8 g and 3.6 g groups were significantly higher than in the placebo group (P < 0.01 and P < 0.05, respectively). ACR50 improvement in the TLHS 4.8 g group was significantly higher compared with the placebo group (P < 0.01). Symptoms of RA were significantly relieved in the TLHS groups. In the TLHS groups, insomnia (n = 1), gastroenteric reactions (n = 2), arrhythmia (n = 1), and minor hepatic lesion (n = 1) were reported; in the placebo group, hepatic dysfunction (n = 1) was reported (P = 0.878).<bold>Conclusions: </bold>TLHS improved the symptoms of patients with RA according to the ACR20. Moreover, TLHS was safe.<bold>Trial Registration: </bold>Chinese Clinical Trial Registry: ChiCTR-TRC-12003871 . Registered on 1 January 2012. [ABSTRACT FROM AUTHOR]

Introduction: <i>Oxytropis racemosa</i> Turcz is an important minority medicine that is used mainly to improve children's indigestion, especially in inner Mongolia and Tibet. Previous studies indicated that the characteristic constituents of this plant are acylated flavonoids.<br>Objective: Rapidly identify the characteristic chemical constituents of <i>O. racemosa</i> by high-performance liquid chromatography-diode array detection-electrospray ionisation/multi-stage mass spectrometry (HPLC-DAD-ESI/MS<i><sup>n</sup></i>) and suggest a useful method to control the quality of this medicinal plant.<br>Methods: In the HPLC fingerprint, 32 flavonoids were tentatively identified by a detailed analysis of their mass spectra, UV spectra and retention times. Furthermore, 13 flavonoids were confirmed by comparison with previously isolated compounds obtained from <i>O. racemosa</i>.<br>Results: In total, 32 flavonoids, including 13 flavonoids with 3-hydroxy-3-methylglutaric acid (HMG) moieties and four flavonoids with 3-malonyl moieties, were identified in the extract of <i>O. racemosa</i>. Among the compounds identified, 10 were characterised as new compounds for their particular acylated sugar moieties.<br>Conclusions: The method described is effective for obtaining a comprehensive phytochemical profile of plants containing unstable acylated flavonoids. The method is also useful for constructing the chromatographic fingerprint of the minority medicine -<i>O. racemosa</i> Turcz for quality control. Copyright © 2012 John Wiley & Sons, Ltd.

Four different extracts of Oxytropis falcata, including the aerial aqueous extract, and the underground aqueous extract, the aerial lipophilic extract, and the underground lipophilic extract were prepared and then administrated orally to mice at the maximum dose (50 g x kg(-1) x d(-1) calculated by raw material) for fifteen days respectively. Compared with the control group, which was administrated of 1.0% tween-80, the treatment groups did not show significant differences in appearance and behavior. However, the organcoefficient, blood biochemical indicator and pathological section results showed that the lipophilic extracts of the aerial and underground parts of O. flacata showed mild injury to the liver of mice, while the aerial and underground aqueous extracts and the underground lipophilic extract showed mild toxicity to the kidney of male mice. Chemical analysis showed that the lipophilic extracts of the aerial and underground parts, especially aerial lipophilic extract, consisted of large amount of flavonoid aglycones with little amount of polysaccharides and proteins, while the aqueous extracts contained much polysaccharides and proteins with almost no flavonoid aglycones detected.
