RESUMEN
OBJECTIVE: To evaluate and compare the efficacy of different mind-body therapies (MBTs) for sleep disturbance in patients with early-stage cancer. METHODS: Randomised controlled trials that included patients (aged ≥18 years) with early stage cancer who underwent MBTs (mindfulness, hypnosis, relaxation, yoga, and qigong) were searched in the CINAHL via the EBSCO Host, Cochrane Library, Embase, MEDLINE, PsycINFO, PubMed, and Scopus databases, from the date of database inception to October 2022. The outcomes were subjective sleep disturbance and objective sleep efficiency. Network meta-analysis (NMA) and comparative effects ranking were performed using STATA (v14.0; STATACorp, College Station, TX, USA). RESULTS: Forty-seven studies investigating five MBTs were included in the NMA. For cancer patients receiving active treatment, mindfulness demonstrated the largest effect size in reducing subjective sleep disturbance (standardised mean difference [SMD]: 0.85; 95% confidence intervals [CI]: 0.20-1.50; Grading of Recommendations Assessment, Development, and Evaluation assessment: moderate), and had the highest cumulative probability compared to usual care or waitlist. For cancer patients who had completed active treatment, qigong demonstrated the largest effect size in reducing subjective sleep disturbance (SMD: 0.99; 95% CI: 0.35-1.63; GRADE: low), followed by hypnosis (SMD: 0.87; 95% CI: 0.32-1.42; GRADE: moderate), and mindfulness (SMD: 0.42; 95% CI: 0.24-0.59; GRADE: moderate). Qigong also demonstrated the largest effect size in improving objective sleep efficiency (weighted mean differences: 10.76; 95% CI: 2.01-19.50; GRADE: low); however, the effect of qigong was tested in only one study in this NMA. Among the eight different treatment conditions, cognitive behavioral therapy (CBT) showed the highest cumulative probability (surface under the cumulative ranking curve: 96.3%) in reducing subjective sleep disturbance and the second highest cumulative probability (SUCRA: 83.3%) in improving objective sleep efficiency. CONCLUSION: There is no evidence supporting the use of MBTs to replace or be comparable to CBT. Mindfulness can be recommended as an optional treatment for reducing sleep disturbance in patients with early-stage cancer. Some support was observed for qigong and hypnosis in reducing sleep disturbances in patients with early-stage cancer who had completed active treatment. More rigorous trials are warranted to confirm whether different forms of MBTs have different effects on sleep in patients with cancer.

OBJECTIVES: To assess whether mind-body therapies (MBTs) are effective for relieving sleep disturbance among patients with cancer. DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: Seven English electronic databases were searched from the date of inception to September 2022. All RCTs that included adults (≥18 years) who were treated with mindfulness, yoga, qigong, relaxation, and hypnosis were screened. The outcome was subjective and/or objective sleep disturbance.The revised Cochrane tool (RoB 2.0) was applied to evaluate the risk of bias. The RevMan software was applied to assessed each outcome according different control groups and assessment time points. Subgroup analyses were performed according to different categories of MBTs. RESULTS: Sixty-eight RCTs (6339 participants) were identified. After requesting for missing data from corresponding authors of included RCTs, 56 studies (5051 participants) were included in the meta-analysis. The meta-analysis showed a significant immediate effect of mindfulness, yoga, relaxation, and hypnosis on subjective sleep disturbance, compared with usual care or wait list control, and the effect of mindfulness lasted at least 6 months. For objective sleep outcomes, we observed significant immediate effects of yoga on wake after sleep onset and of mindfulness on sleep onset latency and total sleep time. Compared with active control interventions, MBTs had no significant effect on sleep disturbance. CONCLUSIONS: Mindfulness, yoga, relaxation, and hypnosis were effective in sleep disturbance severity reduction among patients with cancer at post-intervention, and the effect of mindfulness lasted at least 6 months. Future MBTs studies should apply both objective and subjective sleep measurement tools.

To evaluate the safety and effectiveness of Shenbei Guchang capsules in treatment of diarrhea type irritable bowel syndrome (yang deficiency of spleen and kidney) under widely used conditions, an open, multicenter, controlled, phase Ⅳ clinical trial was conducted in the drug clinical trial centers of 16 domestic hospitals. 2 123 patients from June 10, 2011 to November 29, 2012 were enrolled in the trial. Drug clinical trial was approved by Sichuan Academy of Medical Sciences, Sichuan Provincial People's Hospital Ethics Committee before implementation. Before the start of trial, subjects were selected according to the research scheme and inclusion criteria, then they would step into the 14 d study after signing Informed Consent Form. All subjects were treated according to the research scheme, evaluated the conditions and filled in CFR sheet, to provide the evaluation data and information on safety and efficacy of Shenbei Guchang capsules. Shenbei Guchang capsules were used to treat diarrhea type irritable bowel syndrome in widely used conditions (2 123 cases), and 2 029 cases of them entered FAS set, cure+markedly effective in 1 921 cases, with a comprehensive curative effect rate of 94.68%; 2 010 cases of them entered PPS set, cure+markedly effective in 1 906 cases, with a comprehensive curative effect rate of 94.83%. The primary symptoms of IBS were abdominal pain and diarrhea. After treatment, both abdominal pain and diarrhea were improved, with significant differences (P<0.000 1). There were significant differences in traditional Chinese medicine symptom scores on both post-treatment day 7 and day 14 as compared with the conditions before treatment (P<0.000 1). 35 cases of adverse events occurred during the trial with an incidence of 1.65%, including 12 cases of drug-related adverse events (adverse reaction) with an incidence of 0.57%, mainly manifested as nausea, abdominal distension and dry mouth, most of which would be spontaneously relieved without any measures. No serious adverse events occurred. The commercially available Shenbei Guchang capsules are proved safe and effective for the treatment of diarrhea type irritable bowel syndrome (yang deficiency of spleen and kidney) under widely used conditions (2 123 cases), and can be continued for clinical promotion and application.
RESUMEN
Adenosine can exhibit cytotoxic activity in vivo and in vitro, though its mechanisms are still uncertain. In this study, we investigated the adenosine-mediated apoptotic signaling pathway and the role of NF-kappaB in human hepatocellular carcinoma HepG2 cells. HepG2 cells were treated with different concentrations of adenosine for 12-48 h, and the effect of adenosine on cell proliferation was evaluated by MTT assay. The cytotoxicity of adenosine alone or in combination with an NF-kappaB inhibitor, pyrrolidine dithiocarbamate (PDTC), was also evaluated by MTT assay and the mode of cell death was detected by Hoechst 33342 staining. Cell cycle progress was performed by flow cytometry with PI staining. The protein expressions of Bcl-2, p53, NF-kappaB subunit p65, and caspase-3 were assayed by Western blot. Caspase-3 activity was measured by spectrophotomteric assay. The results showed that adenosine significantly reduced the viability of HepG2 cells in a dose- and time-dependent manner, with IC 50 (24 and 48 h) of 2.52 and 1.89 mmol x L(-1), respectively. The apoptotic index (percentage of sub-G1 phase) of HepG2 cells in adenosine treatment alone for 12 and 24 h or in combination with PDTC were 8.30%, 22.32% and 20.18%, 30.89%, respectively. All of them were higher than that in the control group (0.81%, p < 0.01). The characteristic changes of cell apoptosis (chromatin condensation and sub-G1 peak) were observed under fluorescent microscopy and flow cytometry. We also found that the apoptotic process triggered by adenosine was involved in G0-G1 cell-cycle arrest, enhanced the activity of caspase-3, upregulated p53 and NF-kappaB p65 expression, and downregulated Bcl-2 expression. Inhibition of NF-kappaB by PDTC decreased NF-kappaB p65 expression, enhanced cell apoptosis ratio, and increased caspase-3 activity. NF-kappaB may play an anti-apoptosis role in adenosine-induced HepG2 cytotoxicity.
