Evaluation of Guided Respiration Mindfulness Therapy (GRMT) for Reducing Stress in Nurses.

Guided respiration mindfulness therapy (GRMT) is a clinical model of breathwork that has shown promise as a treatment for depression, anxiety, and stress. This study examined the effectiveness of GRMT as a holistically oriented intervention for reducing psychological distress in nurses. Sixty-two nurses were assigned to either five sessions of GRMT or 5 sessions of a mindfulness-based intervention (MBI) comparison condition which were conducted over 5 weeks. A no-treatment control was also included. Session-by-session change in depression, anxiety, and stress, along with change in mindfulness and self-compassion were assessed. Multilevel analysis showed GRMT resulted in statistically significant reductions in overall psychological distress, anxiety, and stress levels, as well as significant increases in mindfulness and self-compassion with large to very large effect sizes. On all measures, GRMT performed better than the comparison MBI intervention which showed no significant effect on stress levels. Results suggest that GRMT can provide nurses with an effective group intervention for reducing stress, and increasing mindfulness and self-compassion which are foundational elements of self-care for the holistic nurse.

Djulis (Chenopodium formosanum) and Its Bioactive Compounds Protect Human Lung Epithelial A549 Cells from Oxidative Injury Induced by Particulate Matter via Nrf2 Signaling Pathway.

The protective effects of water extracts of djulis (Chenopodium formosanum) (WECF) and their bioactive compounds on particulate matter (PM)-induced oxidative injury in A549 cells via the nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling were investigated. WECF at 50-300 µg/mL protected A549 cells from PM-induced cytotoxicity. The cytoprotection of WECF was associated with decreases in reactive oxygen species (ROS) generation, thiobarbituric acid reactive substances (TBARS) formation, and increases in superoxide dismutase (SOD) activity and glutathione (GSH) contents. WECF increased Nrf2 and heme oxygenase-1 (HO-1) expression in A549 cells exposed to PM. SP600125 (a JNK inhibitor) and U0126 (an ERK inhibitor) attenuated the WECF-induced Nrf2 and HO-1 expression. According to the HPLC-MS/MS analysis, rutin (2219.7 µg/g) and quercetin derivatives (2648.2 µg/g) were the most abundant bioactive compounds present in WECF. Rutin and quercetin ameliorated PM-induced oxidative stress in the cells. Collectively, the bioactive compounds present in WECF can protect A549 cells from PM-induced oxidative injury by upregulating Nrf2 and HO-1 via activation of the ERK and JUN signaling pathways.

The Therapeutic Effects of Traditional Chinese Medicine for Poor Semen Quality in Infertile Males.

Poor sperm quality is one of the main factors of male infertility. Traditional Chinese Medicine (TCM) has been used frequently in clinical practice in many countries to treat a wide array of infertile problems. To further understand the effects of TCM on semen quality, we retrospectively enrolled patients with male infertility and poor semen quality at the Tainan Municipal Hospital in Taiwan between 2013 and 2016. Semen quality analysis in accordance with the WHO criteria is an essential step in the evaluation of male fertility status. Associations between the semen parameters and body mass index, smoking status, alcohol use, duration of infertility, and age were also analyzed. A total of 126 male infertility patients with abnormal semen analysis were included in this study: 50 TCM users and 13 TCM non-users. The basic characteristics of the two groups were not significantly different. TCM users account for 92.5% of the total semen improvement subjects. In conclusion, TCM supplementation may have a beneficial role as improving sperm quality for infertility patients.

[Effects of Feixianping on collagen type I and III in bleomycin induced pulmonary fibrosis rats].

OBJECTIVE: To study the effect of Feixianping (FXP) on collagen type I and II in rats with pulmonary fibrosis (PF). METHODS: Sixty healthy male SD rats were randomly divided into 5 groups, the normal group (A), the model group (B), the positive control group (C) and the two FXP groups (D and E) treated respectively with high and low dose of FXP. Except those in Group A (they were not modeled and administered with normal saline), all rats were established into PF model by intra-tracheal instillation of bleomycin and administered with respective medicines starting from the 1st day after modeling. Rats were sacrificed in batches at 3 time points, the 7th, 14th, and 28th day for observing the pathological changes of lung under light microscope with HE staining and to identify collagen type I and III in lung tissue by immunohistochemical stain and image quantitative analysis. RESULTS: Light-dyeing proliferative collagen fiber was presented in the slightly thickened alveolar wall in lung of modeled rats from the 14th day on, and the pathological changes became more distinct on the 28th day. The highest amount of collagen appeared in the group B, correspondingly, that in all the other groups was much lower (P < 0.05). Reduction of collagen type I and III revealed in both FXP treated groups, but better effect was shown in the high dose FXP group. The effect of FXP was superior to that of positive control on the 14 th day (P <0.05). CONCLUSION: FXP can effectively reduce the abnormal proliferation of collagen in experimental rats with PF.

[Effects of feixianping on serum interleukin-6 and oxygen partial pressure in pulmonary fibrosis rats].

OBJECTIVE: To study the effects of feixianping (FXP) in improving hypoxemia and on serum interleukin-6 (IL-6) in experimental rats with pulmonary fibrosis (PF). METHODS: Two hundred and forty healthy male SD rats were randomly divided into 5 groups, 48 in each group, i.e. the normal control group (A), the model group (B), the prednisone group (C) and the two FXP groups of high (21.6 mg x kg(-1)) and low (10.8 mg x kg(-1)) dosage (D and E). PF model rats were established by intratracheal instillation of bleomycin, excepting those in Group A, to which normal saline was administered. The corresponding treatment to various groups started from the 1st day after modeling. Rats were sacrificed in batch at 4 time points, i.e., the 7th, 14th, 21st and 28th day, their arterial blood was collected for determination of blood partial pressure of oxygen (PaO2) and serum IL-6 content. RESULTS: Serum IL-6 content in Group B at all the time points was higher than that in other groups at the same time points (P<0.01). In the FXP treated groups (D and E), levels of IL-6 at the 7th, 14th and 28th day showed no significant difference from those in Group A and C. Since the 14th day, FXP showed its effect in improving hypoxemia in experimental rats which could basically keep in accordance with the effect of prednisone. CONCLUSION: FXP can ameliorate hypoxemia and reduce the level of serum IL-6 in experimental PF rats.
