Current status of outcome reporting in randomized controlled trials of traditional Chinese medicine for mammary gland hyperplasia: A systematic review

Objective:To assess outcome indicators in clinical trials and provide a reference for establishing a core outcome set to treat hyperplasia of mammary gland(HMG)with traditional Chinese medicine(TCM).Methods:Eight online databases were searched from their inception to December 31,2022,to assess outcomes reported in randomized controlled trials(RCTs)of HMG treated with TCM.The quality of the included studies was assessed according to the Cochrane Risk of Bias Assessment Tool.All outcomes were extracted,classified,and described.Results:A total of 8249 articles were initially retrieved.Of these,70 articles were eligible and involved 10618 participants with HMG.A total of 17 outcome indicators with a frequency of 271 times were involved and were collected according to six outcome domains.Conclusions:The core outcomes of RCTs of HMG treated with TCM are large and divergent.There are problems in evaluation standards,primary and secondary outcomes,TCM characteristic indicators,long-term prognosis,and standardization of reporting.It is recommended to strengthen the trial design and actively construct the core outcome sets with TCM characteristics for HMG.

An exact algorithmic method based on trigonometrical relations to predict the rock quality designation

In core logging, each joint set intersects borehole into some segments. In this research, it has been shown that length of the borehole segments created by each joint set could be computed by trigonometrical relations. By realizing the lengths associated with joint sets, an algorithm has been designed to compute the length of borehole pieces (created by all joint sets) and to calculate RQD. Effect of some factors have been analyzed and applied to the abstract model of the rock mass to have the most similarity to a real rock mass. The program proposed in this study, is a robust platform to calculate the RQD in all directions inside a rock mass without having to deal with the labor of core logging and wrestling with difficulties and inaccuracies of the traditional processes. This is the first algorithmic method for estimating the rock quality which could be employed to develop a new and far more reliable measurement for the degree of jointing inside a rock mass.

Brief ICF Core Set for Obstructive Pulmonary Diseases: Validation from the Perspective of Chinese Respiratory Physicians

Obstructive pulmonary diseases(OPDs)are the leading causes of mortality and disability worldwide.The International Classification of Functioning,Disability and Health(ICF)provides a framework for systemat-ically assessing functioning and disability in patients with chronic diseases.To date,the ICF core sets for OPDs have not been validated by respiratory physicians in China’s mainland.This study was aimed at validating the brief ICF core set for OPDs from the perspective of Chinese respiratory physicians.A three-round,consensus-building survey was conducted with Chinese respiratory physicians from Shanghai,Jiangsu,and Zhejiang from December 2 to December 16,2017,using the Delphi technique.Their answers were analyzed for consensus degree.In this study,52 experts(about 67.3%men)with a mean working experience of(19.3±6.3)years completed the consensus process.After 3 rounds,the following 13 ICF categories were considered crucial for the assessment of OPDs,with an agreement of over 70%:4 in body functions(b410-heart functions,b440-respiratory functions,b455-exercise tolerance functions,and b460-sensations associated with cardiovascular and respiratory functions),2 in body structures(s410-structure of cardiovascular system,and s430-structure of respiratory system),4 in activities and participation(d230-carrying out daily routine,d450-walking,d455-moving around,and d640-doing housework),and 3 in environmental factors(e110-products or substances for personal consumption,e225-climate,and e260-air quality).Twelve(70.6%)categories in the current brief ICF core set were validated,and one additional category,b410-heart functions,was added.In conclusion,Chinese respiratory physicians largely supported the current brief ICF core set for OPDs.However,the newly added and unconfirmed categories need further investigation.

针灸治疗围绝经期随机对照试验的结局指标分析(英文)

Objective:To search systematically the application situation of the outcomes in the randomized controlled trials(RCTs) of perimenopausal syndrome treated with acupuncture and moxibustion so as to provide the foundation for the core outcome sets in treatment of periomenopausal syndrome with acupuncture and moxibustion.Methods:The articles of RTCs on perimenopausal syndrome treated with acupuncture and moxibustion were searched in China National knowledge Infrastructure(CNKI),Wanfang Data Knowledge Service Platform(Wanfang),VIP Chinese Journal Service Platform(VIP),Pubmed,Excerpt medica database(Embase)and Cochrane central register of controlled trials(CENTRAL) databases from January 1,2010 to December31,2020.Two reviewers screened the articles,extracted data and analyzed the application of outcomes in the eligible trials independently.Results:A total of 9391 articles were retrieved initially and 79 articles of them were eligible,including 43 articles in English and 36 articles in Chinese.115 outcomes were involved totally and collected according to 7 outcome domains,of which,the effective rate was the outcome with the highest use frequency.35 articles reported adverse events and 17 articles reported the effect in followup.Conclusion:At present,the outcomes of RCTs on perimenopausal syndrome in treatment with acupuncture and moxibustion are big in divergence,absent in normalization and lack of indicators for long-term prognosis and economics outcomes,as well as have the issues on the incomplete reports on the differentiation between the primary and the secondary outcomes,safety indicators and followup outcomes.It needs to construct the core outcome sets in line with the characteristics of acupuncture-moxibustion discipline so as to improve the quality of clinical trials of acupuncture and moxibustion.
