Optimal modes of mind-body exercise for treating chronic non-specific low back pain: Systematic review and network meta-analysis.

Background: There were limited studies that directly compare the outcomes of various mind-body exercise (MBE) therapies on chronic non-specific low back pain (CNLBP). Objectives: To compare the efficacy of the four most popular MBE modes [Pilates, Yoga, Tai Chi (TC), and Qigong] in clinically CNLBP patients, we conducted a systematic review and network meta-analysis (NMA). Methods: We searched databases for eligible randomized controlled trials (RCTs) (from origin to July 2022). RCTs were eligible if they included adults with CNLBP, and implemented one or more MBE intervention arms using Pilates, yoga, TC, and qigong. In addition, pain intensity and physical function were evaluated using validated questionnaires. Results: NMA was carried out on 36 eligible RCTs involving 3,050 participants. The effect of exercise therapy on pain was in the following rankings: Pilates [Surface under cumulative ranking (SUCRA) = 86.6%], TC (SUCRA = 77.2%), yoga (SUCRA = 67.6%), and qigong (SUCRA = 64.6%). The effect of exercise therapy on function: Pilates (SUCRA = 98.4%), qigong (SUCRA = 61.6%,), TC (SUCRA = 59.5%) and yoga (SUCRA = 59.0%). Conclusion: Our NMA shows that Pilates might be the best MBE therapy for CNLBP in pain intensity and physical function. TC is second only to Pilates in improving pain in patients with CNLBP and has the value of promotion. In the future, we need more high-quality, long-term follow-up RCTs to confirm our findings.

[Current status, challenges and countermeasures of acupuncture data mining literature researches].

Data mining is an analytical method for revealing the implicit internal relations among the data elements, and is also widely used in the field of acupuncture and moxibustion of traditional Chinese medicine. However, there exist some significant deficits in the rationality of design and implementation, preciseness, repeatability, comprehensiveness, objectivity and depth of insights in some current acupuncture data mining researches. In the present paper, we summarized the literature on acupuncture data mining published in the past five years, and analyzed their common shortcomings in the design, implementation and reporting process, including too broad research scope, fuzzy and limited descriptions about the inclusion criteria, not definite retrieval scope and strategy, rarely seen original researches about the assessment of the report quality, lack of detailed descriptions about the literature screening and data processing procedure, incomplete narration about the research outcomes and their clinical significance, and lack of comprehensiveness and subjectiveness and available coping strategies in the discussion of the research papers, etc., in order to promote the improvement of literature methodology and quality of acupuncture data mining research, and then improve the reliability and clinical reference value of such research results.

Are Mind-Body Exercise Beneficial for Treating Pain, Function, and Quality of Life in Middle-Aged and Old People With Chronic Pain? A Systematic Review and Meta-Analysis.

Background: Aging is a significant risk factor in chronic pain development with extensive disability and greater health care costs. Mind-body exercise (MBE) has been scientifically proven to affect the pain intensity and physical health. Objectives: To assess the effects of MBE modes (Tai Chi, yoga, and qigong) for treating chronic pain among middle-aged and old people, compared with nonactive and active treatment, as well as function, quality of life, and adverse events. Methods: We searched PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, and Chinese Scientific Journals Full-Text Database (VIP) till March 2022. No restrictions were chartered within the year and language of publication. We included randomized controlled trials of MBE treatment in middle-aged and elderly people with chronic pain. The overall certainty of evidence was evaluated by using the GRADE approach. Results: A total of 17 studies (n = 1,332) were included in this review. There was low-certainty evidence indicating that MBE had a moderate effect on reducing pain compared with the nonactive and active control group (standard mean difference (SMD): -0.64, 95% confidence interval (CI): -0.86 to -0.42, P < 0.001). Very-low-certainty evidence showed that the pooled SMD for the functional improvement was -0.75 (95% CI: -1.13 to -0.37, P < 0.001). Low-certainty evidence presented that no influence was observed in physical component summary (SMD: 0.23, 95% CI: -0.16 to 0.62, P = 0.24) and mental component summary (SMD: -0.01, 95% CI -0.39 to 0.36, P = 0.95). Conclusion: Our results indicated that MBE was an effective treatment for reducing symptoms of middle-aged and elderly people with chronic pain compared with nonactive and active control groups. TC and qigong had obvious benefits for knee osteoarthritis in self-reported function, but the efficacy of chronic low back pain was uncertain. No significant benefit of MBE on quality of life in older adults with chronic pain was found. More high-quality RCTs should be conducted to explore the efficacy and mechanism of MBE on chronic pain in middle-aged and elderly people from various dimensions, such as affective and cognitive dimensions.

Effectiveness and safety of acupuncture for chronic obstructive pulmonary disease: A protocol for systematic review and meta-analysis.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is the most common respiratory disease in clinic. Traditional Chinese medicine (TCM) lung rehabilitation has gradually been valued in the field of prevention and treatment of COPD. Acupuncture, as an important part of TCM lung rehabilitation, is carried out in clinical extensively and application. It has the advantage of improving the symptoms and quality of life of COPD cases, but the evidence-based proof is limited. METHODS: Eight databases will be systematically retrieved from their inceptions to December 2021. This study will include randomized controlled trials of acupuncture in the treatment of COPD with stable stage. The main outcome will include clinical effective rate, TCM symptom score, quality of life, dyspnea, exercise capacity, lung function, frequency of acute exacerbation, adverse events. Literature screening, quality evaluation and information extraction will be completed by two independent researchers. Revman 5.3 software will be used to perform meta-analysis. Assessment of multiple systematic reviews-2 tool will be used for evaluating the methodological quality of systematic review (SR), grading of recommendations assessment will for rating the quality of evidence, and consolidated standards of reporting trials and Standards for Reporting Interventions in Clinical Trials of Acupuncture tool will for assessing the reporting quality of randomized controlled trials. RESULTS: The findings of this SR will be presented at relevant conferences and submitted for peer-review publication. CONCLUSIONS: The findings of this SR will provide up-to-date summary proof for evaluating the effectiveness and safety of acupuncture for COPD.

High-throughput screening identifies established drugs as SARS-CoV-2 PLpro inhibitors.

A new coronavirus (SARS-CoV-2) has been identified as the etiologic agent for the COVID-19 outbreak. Currently, effective treatment options remain very limited for this disease; therefore, there is an urgent need to identify new anti-COVID-19 agents. In this study, we screened over 6,000 compounds that included approved drugs, drug candidates in clinical trials, and pharmacologically active compounds to identify leads that target the SARS-CoV-2 papain-like protease (PLpro). Together with main protease (Mpro), PLpro is responsible for processing the viral replicase polyprotein into functional units. Therefore, it is an attractive target for antiviral drug development. Here we discovered four compounds, YM155, cryptotanshinone, tanshinone I and GRL0617 that inhibit SARS-CoV-2 PLpro with IC50 values ranging from 1.39 to 5.63 µmol/L. These compounds also exhibit strong antiviral activities in cell-based assays. YM155, an anticancer drug candidate in clinical trials, has the most potent antiviral activity with an EC50 value of 170 nmol/L. In addition, we have determined the crystal structures of this enzyme and its complex with YM155, revealing a unique binding mode. YM155 simultaneously targets three "hot" spots on PLpro, including the substrate-binding pocket, the interferon stimulating gene product 15 (ISG15) binding site and zinc finger motif. Our results demonstrate the efficacy of this screening and repurposing strategy, which has led to the discovery of new drug leads with clinical potential for COVID-19 treatments.

Structure of Mpro from SARS-CoV-2 and discovery of its inhibitors.

A new coronavirus, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the aetiological agent responsible for the 2019-2020 viral pneumonia outbreak of coronavirus disease 2019 (COVID-19)1-4. Currently, there are no targeted therapeutic agents for the treatment of this disease, and effective treatment options remain very limited. Here we describe the results of a programme that aimed to rapidly discover lead compounds for clinical use, by combining structure-assisted drug design, virtual drug screening and high-throughput screening. This programme focused on identifying drug leads that target main protease (Mpro) of SARS-CoV-2: Mpro is a key enzyme of coronaviruses and has a pivotal role in mediating viral replication and transcription, making it an attractive drug target for SARS-CoV-25,6. We identified a mechanism-based inhibitor (N3) by computer-aided drug design, and then determined the crystal structure of Mpro of SARS-CoV-2 in complex with this compound. Through a combination of structure-based virtual and high-throughput screening, we assayed more than 10,000 compounds-including approved drugs, drug candidates in clinical trials and other pharmacologically active compounds-as inhibitors of Mpro. Six of these compounds inhibited Mpro, showing half-maximal inhibitory concentration values that ranged from 0.67 to 21.4 µM. One of these compounds (ebselen) also exhibited promising antiviral activity in cell-based assays. Our results demonstrate the efficacy of our screening strategy, which can lead to the rapid discovery of drug leads with clinical potential in response to new infectious diseases for which no specific drugs or vaccines are available.
