The efficacy and safety of traditional Chinese medicine Guilu Erxian Jiao in the treatment of knee osteoarthritis: A systematic review and meta-analysis

ObjectiveA systematic review was conducted to investigate the efficacy of Guilu Erxian Jiao (GEJ) in the treatment of knee osteoarthritis (OA).MethodsWe searched PubMed, MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Chinese Electronic Periodical Services, and ClinicalTrials.gov to identify relevant randomized controlled trials or controlled clinical trials, from the inception of each source to April 20, 2021. Primary outcome included overall efficacy, pain score, and Lequesne index score; secondary outcome included adverse events. Methodological quality was assessed using the Cochrane risk of bias tool (RoB 1.0). The meta-analysis was performed based on a random-effects model due to anticipated clinical heterogeneity. The grading of overall evidence was assessed using the GRADE system. The study protocol was registered on PROSPERO (CRD42021233573).ResultsEight studies were included. Compared to controls, GEJ exhibited superior overall efficacy for treating OA (risk ratio (RR) = 1.20; 95% confidence interval (CI) = 1.06–1.35). Regarding pain score, there was no statistical difference between GEJ and controls (standardized mean difference (SMD) = 0.27; 95% CI = −0.91 – 1.46). No significant difference was found in Lequesne score between GEJ and controls (MD = −0.25; 95% CI = −0.52 – 0.01). No statistical difference in adverse reactions was observed between GEJ and controls (risk difference (RD) = −0.01; 95% CI = −0.05–0.03).ConclusionOur findings suggest that GEJ may have positive effects on overall efficacy in treating OA. However, there is insufficient evidence regarding pain score, Lequesne score, and knee joint function score.     

Prospective feasibility study of a mindfulness-based program for breast cancer patients in the southeastern US

BackgroundMindfulness interventions can improve psychological distress and quality of life (QoL) in cancer survivors. Few mindfulness programs for cancer recovery exist in Southeastern U.S. The primary objective of this study was to assess the feasibility of a modified mindfulness-based stress reduction (MBSR) program for breast cancer patients in Birmingham, Alabama. The secondary objective was to explore potential program effects on mindfulness skills and QoL.MethodsThis study was a prospective, quasi-experimental feasibility study conducted over 10 months at a university hospital. Feasibility was achieved if 80% of eligible patients screened enrolled in the study and 70% of enrolled patients attended all 8 program sessions. Effectiveness was estimated by changes in mindfulness and QoL indicators measured with validated scales administered at 3 time points and assessed with a non-parametric Friedman test. Sessions included meditation, yoga, and an attention practice called body scan. There were 3 groups of 2–5 patients.ResultsThe sample totaled 12 patients. Forty-four percent (12/27) of eligible patients enrolled in the study, and two out of 12 enrolled patients completed 8 program sessions, resulting in 16.7% (2/12) retention. However, more than half (66.7%) of participants completed at least 7 sessions. Between baseline and 8-week follow-up, patients demonstrated statistically significant improvements in distress, general wellbeing, and fatigue-related QoL.ConclusionsFeasibility objectives were not achieved. However, a majority of participants (66.7%) completed 7 of 8 program sessions. Program effects were promising for distress, fatigue, and wellbeing. Results warrant further research on MBSR-like programs for breast cancer patients in Alabama.

应激反应对心肌缺血再灌注损伤的影响

探讨应激反应对心肌缺血再灌注损伤的保护作用及其机制。方法：按改良的Ｋａｎｅ方法,制备 心肌缺血再灌注损伤模型。观察结扎左冠状动脉前、后的 １、５、１０ｍｉｎ及再灌注１０ｍｉｎ内心功能指标及再灌注期 间的室速（ＶＴ）、室颤（ＶＦ）发生率及动物死亡率（Ｍ）,并测定心肌丙二醛（ＭＤＡ）含量及超氧化物歧化酶（ＳＯＤ）的活 性与对照组比较。结果：实验组的心功能明显的得到了改善;ＶＴ、ＶＦ及Ｍ均明显降低;心肌内ＭＤＡ含量明显减 少,而ＳＯＤ的活性则明显增加.结论：应激反应具有抗心肌缺血再灌注损伤作用,主要作用机制与其增强心肌内 源性抗氧化能力有关。
