Effects of mindfulness training on clinical efficacy in patients with nitrous oxide addiction / 中华行为医学与脑科学杂志

Objective:To study the effect of mindfulness-based training intervention on clinical efficacy in patients with nitrous oxide(laughing gas) addiction.Methods:From June 2019 to June 2020, sixty-six patients with nitrous oxide addiction in Beijing Gaoxin Hospital were selected and randomly divided into experimental group( n=33) and control group( n=33). The control group received Taijiquan training and physical training, while the experimental group added mindfulness-based training intervention on the basis of Taijiquan training and physical training.Symptom checklist 90 (SCL-90) scores and visual analog scales (VAS) craving scores were compared between the two groups at admission and 8 weeks after treatment.SPSS 22.0 software was used for statistical analysis.Independent sample t test and paired sample t test were used to compare the differences between groups and within groups. Results:(1)Before treatment, there were no significant differences in subscale scores of SCL-90 between the two groups except for depression factor((2.45±0.86), (2.03±0.46), t=2.474, P<0.05). After treatment, the subscale scores of somatization((1.38±0.35), (1.68±0.34), t=-3.656, P<0.05), phobic anxiety((1.49±0.37), (1.81±0.30), t=-3.993, P<0.05), paranoid ideation((1.50±0.47), (1.88±0.31), t=-3.898, P<0.05) and psychotism((1.34±0.54), (1.55±0.27), t=-3.094, P<0.05) of SCL-90 in the experimental group were significantly lower than those in the control group.(2)Before treatment, there was no significant difference in VAS craving score between the two groups( t=0.857, P=0.395). After treatment, the score of VAS in the experimental group was significantly lower than that in the control group( t=27.427, P<0.05). Conclusion:Mindfulness training intervention can effectively improve the clinical symptoms of patients with nitrous oxide addiction, which is worthy of clinical application.

Clinical research of auricular gold-needle therapy in treatment of chronic fatigue syndrome of deficiency constitution / 中国针灸

OBJECTIVE@#To observe the clinical therapeutic effects of auricular gold-needle therapy on chronic fatigue syndrome of deficiency constitution and explore its potential mechanism.@*METHODS@#A total of 120 patients were randomized into an auricular gold-needle therapy group, an auricular point pressure therapy group and a Chinese herb group, 40 cases in each one. Additionally, a health control group (40 cases) was set up, without any intervention. In the auricular gold-needle therapy group, the gold needle was used to stimulate the auricular points on one side and the cowherb seed pressure therapy on the other side. In the auricular point pressure therapy group, the cowherb seed pressure therapy was adopted only on one side. The auricular points were shen (CO), xin (CO), fei (CO), pizhixia (AT), etc. in the two groups. The auricular points on both sides were used alternatively. The treatment was given once a week, 4 treatments as one course and the consecutive 3 courses of treatment were required. In the Chinese herb group, was prescribed for oral administration, 6 g, twice a day, the medication for 1 month was as one session and the consecutive 3 sessions of medication were required. Before and after treatment, separately, the clinical symptom score, the levels of the serum immunoglobulins, i.e. IgA, IgG and IgM were observed in the patients of the three groups. The therapeutic effects were evaluated in the three groups.@*RESULTS@#The total effective rate was 90.0% (36/40) in the auricular gold-needle therapy group, better than 80.0% (32/40) in the auricular point pressure therapy group and 82.5% (33/40) in the Chinese herb group (both <0.05). Before treatment, the clinical symptom scores of the patients in the three groups were obviously higher than the health control group (all <0.001). After treatment, the symptom scores were all reduced as compared the scores before treatment in the three groups (all <0.001) and the symptom scores in the auricular gold-needle therapy group were better than the auricular point pressure therapy group and the Chinese herb group (both <0.01). Before treatment, the levels of serum IgA, IgG and IgM of the patients in the three groups were lower than the health control group (all <0.001). The levels were all improved after treatment in the three groups (all <0.01), and the levels in the auricular gold-needle therapy group was better than the auricular point pressure therapy group and the Chinese herb group (all <0.05).@*CONCLUSION@#The auricular gold-needle therapy achieves the significant therapeutic effects on chronic fatigue syndrome of deficiency constitution and its mechanism is probably related to the regulation of immune function.

Novel Isochroman Dimers from Stachybotrys sp. PH30583: Fermentation, Isolation, Structural Elucidation and Biological Activities.

The rare anishidiol and five new isochromans, including three novel dimers with unprecedented skeletons, were isolated from Stachybotrys sp. PH30583. Their structures were determined by spectral analyses. The bioactivities of these compounds were also investigated. The dimers (6-10) inhibited acetylcholinesterase at 50 µM, but the monomers did not. To investigate the biogenesis of the novel dimers, a time-course investigation of metabolite production was undertaken.

External application of traditional Chinese medicine in the treatment of bone cancer pain: a meta-analysis.

BACKGROUND: Bone cancer pain presents a clinical challenge with limitations of current treatments. Many patients seek additional therapies that may relieve pain. Many external applications of traditional Chinese medicines (EAs-TCMs) have been evaluated in clinical trials, but fewer are known about them outside of China. The objective of this study is to assess the efficacy for bone cancer pain. METHODS: A systematic literature search was conducted in seven databases until December 2014 to identify randomized controlled trials (RCTs) about EAs-TCMs in the treatment of bone cancer pain. The primary outcome was total pain relief rate. The secondary outcomes were adverse events at the end of treatment course. The methodological quality of RCTs was assessed independently using six-item criteria according to the Cochrane Collaboration. All data were analyzed using Review Manager 5.2.0. We included any RCTs evaluating an EA-TCM for the treatment of bone cancer pain. We conducted a meta-analysis. RESULTS: We included six RCTs with 534 patients. In general, the reporting of methodological issues was poor. Compared with morphine sulfate sustained release tablets (MSSRTs) or radiotherapy or bisphosphonates, we analyzed data from five trials reporting on complete response effect score (relative risk (RR) = 5.38, 95% confidence interval (CI) = 2.80-10.31, P < 0.00001) and partial response (RR = 1.18, 95% CI = 1.02-1.37, P = 0.02) and six trials reporting on total pain relief rate (RR = 1.49, 95% CI = 1.43-1.67, P < 0.00001). Six RCTs showed significant effects of EA-TCM for improving pain relief in patients with bone cancer pain. In addition, no severe adverse events were found. CONCLUSION: This systematic review showed positive but weak evidence of EA-TCM for bone cancer pain because of the poor methodological quality and the small quantity of the included trials. Future rigorously designed RCTs are required.

Effect and mechanism of Bushen Huoxue recipe on ovarian reserve in mice with premature ovarian failure / 华中科技大学学报（医学）（英德文版）

The aim of the present study was to explore the effect and mechanism of Bushen Huoxue recipe (BHR) on ovarian reserve in mice with premature ovarian failure (POF). Mice were divided into 3 groups: normal group, model group and BHR group. Intraperitoneal injection of cyclophosphamide was performed to create the POF model. Primordial follicular (PDF) number, ovarian wet weight, ovarian index, and estrous cycle were analyzed to evaluate the effect of BHR on POF. Meanwhile, the mRNA and protein level of Mouse Vasa Homologue (MVH) in the bone marrow, peripheral blood and ovary were detected, to explore the underlying mechanism of the treatment efficacy of BHR on ovarian reserve. By the time of BHR treatment for 28 days, BHR increased the PDF number and shortened the estrous cycle of POF mice. BHR also decreased the mRNA level of MVH in the bone marrow, and increased mRNA and protein level of MVH in the ovary of POF mice. Our results demonstrated a treatment efficacy of BHR on POF mice, and revealed that BHR might repair the dysfunction of germline stem cells in the bone marrow, and thus to improve the ovarian reserve and enhance the ovarian function of POF mice through neo-oogenesis.

Ganoderma lucidum extract protects dopaminergic neurons through inhibiting the production of inflammatory mediators by activated microglia / 生理学报

Abundant evidence has suggested that neuroinflammation participates in the pathogenesis of Parkinson's disease (PD). The emerging evidence has supported that microglia may play key roles in the progressive neurodegeneration in PD and might be a promising therapeutic target. Ganoderma lucidum (GL), a traditional Chinese medicinal herb, has been shown potential neuroprotective effect in our clinical trials that lead us to speculate that it might possess potent anti-inflammatory and immunomodulating properties. To test this hypothesis, the present study investigated the potential neuroprotective effect of GL and underlying mechanism through inhibiting microglial activation using co-cultures of dopaminergic neurons and microglia. The cultures of microglia or MES23.5 cells alone or together were treated for 24 h with lipopolysaccharide (LPS, 0.25 μg/mL) as a positive control, GL extracts (50-400 μg/mL) or MES23.5 cell membrane fragments (150 μg/mL) were used in treatment groups. Microglia activation, microglia-derived harmful factors and [(3)H]dopamine ([(3)H]DA) uptake of MES23.5 cells were analyzed. The results showed that microglia were activated by LPS and MPP(+)-treated MES23.5 cell membrane fragments, respectively. Meanwhile, GL extracts significantly prevented the production of microglia-derived proinflammatory and cytotoxic factors, including nitric oxide, tumor necrosis factor-α (TNF-α) and interleukin 1β (IL-1β), in a dose-dependent manner and down-regulated the TNF-α and IL-1β expressions on mRNA level. In addition, GL extracts antagonized the reduction of [(3)H]DA uptake induced by MPP(+) and microglial activation. In conclusion, these results suggest that GL may be a promising agent for the treatment of PD through anti-inflammation.
