Effects of 12 weeks of Tai Chi Chuan intervention on the postural stability and self-reported instability in subjects with functional ankle instability: Study protocol for a randomized controlled trial.

Background: Tai Chi Chuan (TCC) is a physical activity modality that originated in China and is now widely popular around the world. Although there are a series of articles reporting that TCC can improve balance and other functional symptoms in a variety of populations, including the elderly, patients with stroke, and patients with Parkinson's disease, its efficiency has not been scientifically and methodically evaluated in subjects with functional ankle instability (FAI). Moreover, there is no literature directly comparing TCC and conventional balance training (CBT) interventions for FAI. The objective of this study is to investigate the comparative effects of TCC intervention and CBT protocols in improving postural balance and subjective instability feelings in patients with FAI. Methods: This study will be a single-center, parallel group, randomized controlled trial. Sixty-eight patients with FAI will be included and randomly assigned in a 1:1 ratio to either an intervention group (n =34) or a control group (n = 34). The participants in the intervention group will complete 12 weeks of TCC intervention (40 min/time, 3 times/week for 12 weeks) on the basis of health education treatment. The control group will receive health education and 36 CBT sessions during a 12-week period. Outcome measures include postural stability and self-reported feelings of instability at baseline, after the end of the intervention, and 3-month follow-up. The postural stability assessment of patients with FAI will be detected by performing static and dynamic postural tests, which will be carried out through a specific balance platform (TecnoBody ProKin). Self-reported feelings of instability will be assessed by Cumberland Ankle Instability Tool (CAIT), American Orthopedics Foot and Ankle Society's Ankle-Hindfoot Evaluation Scale (AOFAS-AHES), and the MOS item Short Form Health Survey (SF-36). Discussion: This trial will demonstrate whether a 12-week TCC intervention positively affects postural stability and self-reported outcomes in patients with FAI. At the same time, the superiority of its clinical efficacy will also be compared with that of CBT. This study may also help to redefine the value of traditional Chinese exercises in the treatment of chronic ankle instability.

Postoperative analgesic effect of acupotomy combined with patient-controlled analgesia in patients undergoing video-assisted thoracoscopic surgery: a study protocol for a randomized controlled trial.

BACKGROUND: Postoperative acute pain is a common issue following thoracic surgery. Acupotomy is a common and safe intervention method for pain treatment in clinical practice. In previous preliminary experiments, we found that acupotomy has a good clinical effect and good safety in the treatment of pain after thoracoscopic surgery. However, due to a lack of a rigorous design and an adequate sample size, its efficacy still requires further confirmation. The purpose of this study will be to explore the efficacy and safety of acupotomy combined with patient-controlled analgesia (PCA) for the treatment of pain after video-assisted thoracic surgery (VATS). METHODS: The study will be a single-centre, parallel group, randomized controlled trial. Seventy patients with significant pain after thoracoscopic surgery with a visual analogue scale (VAS) score ≥ 7 will be included and randomly distributed into two groups: G1, the acupotomy combined with PCA group; and G2, the conventional PCA group. The primary outcome measure is pain scores at rest and coughing evaluated with the VAS by a blinded observer in the postanaesthesia care unit (PACU) and postoperatively at 1, 2, 4, 8, 12, 24, 48, and 72 h. The secondary outcome measures are postoperative requirements for rescue analgesia, the cumulative amount of self-administered analgesics, the level of sedation (LOS), the Bruggemann comfort scale (BCS), and the functional activity score (FAS) concerning adverse effects and patient satisfaction. DISCUSSION: This trial has the potential to identify an innovative and effective analgesic method for postoperative pain management for VATS. The findings may advocate for the inclusion of the treatment of comorbid pain after thoracoscopy in current pain management practice guidelines.

Acupotomy therapy for lumbar disc herniation: Protocol for a systematic review and meta-analysis.

BACKGROUND: Lumbar disc herniation (LDH) is a clinically common degenerative spinal disease that adversely affects patients' quality of life and work ability. Although several articles have reported that acupotomy can improve the clinical symptoms of LDH, the efficiency of acupotomy has not been scientifically or methodically evaluated. The primary objective of this study is to evaluate and synthesize evidence on the effectiveness and safety of acupotomy therapy in patients with LDH. METHOD: We plan to search eight English and Chinese electronic databases, including the Web of Science, Cochrane Library, PubMed, EMBASE, SinoMed, Wanfang, China Science and Technology Journal (VIP), and China National Knowledge Infrastructure (CNKI) databases, for potentially eligible studies. Randomized controlled trials (RCTs) on acupotomy treatment in LDH patients will be searched for independently by 2 reviewers in the databases from their inception to August 2018. We will combine data from clinically homogenous studies in a fixed effect meta-analysis using RevManV.5.3.5, and the evidence level will be assessed by using the method for Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: This systematic review and meta-analysis will use high-quality evidence-based medicine to assess the efficacy and safety of acupotomy therapy in LDH. CONCLUSION: This study protocol will provide strong evidence to determine whether acupotomy therapy is an effective and safe intervention for patients with LDH.

Dual B cell immunotherapy is superior to individual anti-CD20 depletion or BAFF blockade in murine models of spontaneous or accelerated lupus.

OBJECTIVE: To determine whether a combination of B cell depletion and BAFF blockade is more effective than monotherapy in treating models of spontaneous or accelerated systemic lupus erythematosus (SLE) in (NZB × NZW)F1 mice. METHODS: Clinical parameters such as disease progression-free survival, proteinuria, and renal injury were assessed in models of spontaneous, interferon-α (IFNα)-accelerated, or pristane-accelerated lupus in (NZB × NZW)F1 mice. Treatment arms included anti-CD20 (B cell depletion), B lymphocyte stimulator receptor 3 fusion protein (BR-3-Fc) (BAFF blockade), the combination of anti-CD20 and BR-3-Fc, isotype control, or cyclophosphamide. In models of spontaneous, IFNα-accelerated, or pristane-accelerated lupus, mice were treated for 24 weeks, 8 weeks, or 12 weeks, respectively. Peripheral and resident B cell subsets and various autoantibodies were examined. RESULTS: Compared to B cell depletion or BAFF blockade alone, combined therapy significantly improved disease manifestations in all 3 lupus models. In addition, marginal zone B cells, plasmablasts, and circulating and tissue plasma cells were decreased more effectively. Dual B cell immunotherapy also reduced multiple classes of pathogenic autoantibodies, consistent with its observed effectiveness in reducing immune complex-mediated renal injury. CONCLUSION: Dual immunotherapy via B cell depletion and BAFF blockade is more efficacious than single agent immunotherapy in murine SLE models, and this combination treatment is predicted to be an effective strategy for immunotherapy in human SLE.
