Two new iridoid glycosides designated as senburiside III (2) and senburiside IV (3), together with one known iridoid glycoside senburiside I (1) and three known secoiridoid glucosides swertiamarin (4), gentiopicroside (5) and sweroside (6), were isolated from the whole plant of Swertia franchetiana. The structures of the two new compounds were elucidated by spectroscopic methods.;
Two new monoterpenes, 3-(2-oxo-4-methyl-3-pentenyl)furan-5H-2-one (1) and 3-[(2E)-4-hydroxyl-4-methyl-2-pentenyl)]furan-5H-2-one (2), along with eight known compounds (3-10), were isolated from the stalks and infructescence of Sibiraea laevigata. Their structures were elucidated by spectroscopic methods including extensive 1D and 2D NMR techniques. In addition, all of these isolates were evaluated for their cytotoxic and antioxidant activities. The results showed that compounds 5-7 displayed cytotoxicity with IC50 values ranging from 34.8 to 43.2 μg ml-1 against tumor cell lines. Furthermore, 5 and 9 showed antioxidant activities.
A sensitive and inexpensive method involving ultrasound-assisted dispersive liquid-liquid microextraction (UA-DLLME) and pre-column derivatization followed by high-performance liquid chromatography with fluorescence detection (HPLC-FLD) was developed for the analysis of glycyrrhetinic acid. In this work, glycyrrhetinic acid could be obtained by hydrolyzing glycyrrhizic acid to remove glucuronic acid and subsequently extracted by UA-DLLME using chloroform and acetone as the extraction and disperser solvents, respectively. The sample extraction was firstly concentrated to dry under nitrogen and then rapidly derivatized with 2-(12-oxobenzo[b]acridin-5(12H)-yl)-ethyl-4-toluenesulfonate (BAETS) after the UA-DLLME. The prime parameters influencing the UA-DLLME and derivatization procedure were optimized using response surface methodology. Under the optimum conditions, the proposed method has a better linearity in a wider range of 6-300 ng mL<sup>−1</sup> and a high square of correlation coefficient (<i>R</i> <sup>2</sup>) at 0.9994. Limit of detection and limit of quantification were found to be 1.7 ng mL<sup>−1</sup> and 5.8 ng mL<sup>−1</sup>, respectively. The proposed method was applied to the analysis of glycyrrhetinic acid in liquorice, liquorice apricot and sugar plum samples. For the analysis of the spiked samples, the spiked recoveries were in the range of 90.4-103.0 % with RSD less than 5.18 %. All results demonstrated that the UA-DLLME-HPLC-FLD (ultrasound-assisted dispersive liquid-liquid microextraction-high-performance liquid chromatography with fluorescence detection) was a sensitive, accurate, efficient analytical method for the determination of glycyrrhetinic acid.
Background: A small percentage of patients screen positive for depression following a mindfulness-based program. We identified patient characteristics associated with this outcome in order to understand this phenomenon.Methods: Depressive symptoms, stress, mindfulness, coping with illness and sense of coherence were measured in 126 patients with various medical and psychological conditions pre- and post- Mindfulness-Based Stress Reduction (MBSR).
Results: Fewer patients (27% vs. 49%) screened positive for depression post-MBSR. Both pre- and post-MBSR patients who were depressive following MBSR scored lower on meaningfulness, comprehensibility, and manageability (sense of coherence), higher on emotional coping and lower on palliative and distraction coping. Smaller positive changes (e.g. stress) occurred in these patients as well. Viewing life as less meaningful pre-MBSR predicted more symptoms of depression post-MBSR.
Conclusions: Patients who suffered depressive symptoms following the program were unable to reappraise their lives in such a way as to become stress resilient.

Background: Yoga, as a mind-body therapy, is effective in improving quality of life for patients with chronic diseases, yet little is known about its effectiveness in female heroin addicts. Objectives: The aim of this study was to evaluate the effects of yoga on mood status and quality of life among women undergoing detoxification for heroin dependence in China. Method: This study was a randomized controlled trial. Seventy-five women aged 20-37 years undergoing detoxification for heroin dependence at AnKang Hospital were allocated randomly into an intervention or a control group. Women in the intervention group received a 6-month yoga intervention in addition to hospital routine care, and women in the control group received hospital routine care only. Mood status and quality of life were assessed using the Profile of Mood States and Medical Outcomes Study 36-item Short-Form Health Survey at baseline and following 3 and 6 months of treatment. Repeated-measures analysis of variance was used to evaluate treatment and time effects on mood and quality of life. Results: Most female heroin addicts were young and single, with a low education level. Most had used heroin by injection. Mood state and quality of life of female heroin addicts were poor. The intervention group showed a significant improvement in mood status and quality of life over time compared with their counterparts in the control group. Conclusion: Yoga may improve mood status and quality of life for women undergoing detoxification for heroin dependence. Yoga can be used as an auxiliary treatment with traditional hospital routine care for these women.
