Exercise...BACKGROUND： Chronic obstructive pulmonary disease （COPD） is a major public health problem worldwide. Pulmonary rehabilitation （PR） is an established intervention for the management of patients with COPD. Exercise training is an important part of PR, and its effectiveness in patients with COPD is well established. However, alternative methods of PR training such as Daoyin have not been appropriately studied. Hence, alternative forms of exercise training that require less exercise equipment and no specific training place should be evaluated. This paper describes the study protocol of a clinical trial that aims to determine if pulmonary Daoyin training will improve the exercise capacity and psychosocial function of patients with COPD in China. METHODS AND DESIGN： A multicenter, randomized, controlled trial will be conducted. A total of 464 patients meeting the inclusion criteria will be enrolled into this study with 232 patients in each of the trial group and the control group. Based on patient education, patients in the trial group will receive pulmonary Daoyin and continue with their usual therapy for three months. In the control group, patients will continue with their usual therapy. The primary outcome measures are exercise capacity assessed by the six-minute walking distance test and lung function. Secondary outcomes include dyspnea and quality of life. Measurements will be taken at baseline （month 0） and after the study period （month 3）. DISCUSSION： It is hypothesized that pulmonary Daoyin will have beneficial effects in improving exercise capacity and psychosocial function of patients with stable COPD, and will provide an alternative form of exercise training that is accessible for the large number of people with COPD. TRIAL REGISTRATION： This trial has been registered in ClinicalTrials.gov. The identifier is NCT01482000.展开更多

Currently, few treatments are available for IPF. Clinical practice of traditional Chinese medicine(TCM), using a syndrome differentiation approach, offers some treatment success in IPF. However, there is no sufficient evidence-based study of the role of TCM in IPF management to make strong conclusions. This study evaluates the efficacy and safety of TCM in the treatment of IPF.Methods and design: A multicenter, exploratory, randomized, double-blind and placebo-controlled trial is planned. A total of 80 patients will be enrolled in the study, which will include 26 weeks of treatment.Participants will be randomly assigned into TCM group or control group in a 1:1 ratio. The TCM group will be given TCM granules based on syndrome differentiation. Formulae include Bao-fei Hua-xian granule for lung qi deficiency, Jin-shui Huan-xian granule for lung-kidney qi deficiency and Yang-qing Kang-xian granule for yin deficiency and inner heat. The control group will be given a corresponding TCM granule placebo. The efficacy and safety of interventions will be evaluated by the outcome variables,including frequencies of acute exacerbations, pulmonary function, clinical symptoms, dyspnea, healthrelated quality of life(HRQo L), 6-minute walk distance and safety indicators.Discussion: It is hypothesized that TCM will decrease the frequency of adverse events, improve pulmonary function and HRQo L, based on our clinical experience. This trial is the first study of TCM treatment in IPF that is based on syndrome differentiation and will evaluate the efficacy and safety of TCM in IPF.展开更多

Over the past decade, a worldwide trend toward increasing glomerular filtration rate at the initiation of dialysis has been noted. However, available data indicate that early dialysis has no survival benefit or is harmful. Peritoneal dialysis (PD) is one alternative for ESRD and has potential survival factors different from those of hemodialysis. The association between the timing of PD initiation and survival is unclear. This review examines the effect of the timing of dialysis on clinical outcomes in PD patients.展开更多

The present study aimed to establish an alternate tool by building a predictive model to evaluate the probability of proliferative LN. Methods： In this retrospective cohort with biopsy-proven LN, 382 patients in development cohort, 193 in internal validation cohort, and 164 newly diagnosed patients in external validation cohort were selected. Logistic regression model was established, and the concordance statistics （C-statistics）, Akaike information criterion （AIC）, integrated discrimination improvement, Hosmer-Lemeshow test, and net reclassification improvement were calculated to evaluate the performance and validation of models. Results： The prevalence of proliferative LN was 77.7% in the whole cohort. A model, including age, gender, systolic blood pressure, hemoglobin, proteinuria, hematuria, and serum C3, performed well on good-of-fit and discrimination in the development chohort to predict the risk of proliferative LN （291 for AIC and 0.84 for C-statistics）. In the internal and external validation cohorts, this model showed good capability for discrimination and calibration （0.84 and 0.82 for C-statistics, and 0.99 and 0.75 for P values, respectively）. Conclusion： This study developed and validated a model including demographic and clinical indices to evaluate the probability of presenting proliferative LN to guide therapeutic decisions and outcomes.展开更多
