ABSTRACT
To explore the clinical characteristics of patients infected with SARS-CoV-2 nationwide, especially the effect factors of asymptomatic infection and disappearance of clinical symptoms. A total of 66,448 COVID-19 patients in China who have been diagnosed by nucleic acid test or rapid antigen test were surveyed online (December 24, 2022 to January 16, 2023). Our cross-sectional study used descriptive analyses and binary Logistics regression model to assess the correlation between the clinical characteristics and relative factors, including age, gender, pre-existing conditions, reinfection, vaccination and treatment. A total of 64,515 valid questionnaires were collected. Among included participants, 5969 of which were asymptomatic. The symptoms were mainly upper respiratory symptoms, including dry and itchy throat (64.16%), sore throat (59.95%), hoarseness (57.90%), nasal congestion (53.39%). In binary Logistics regression model, we found that male, no pre-existing conditions, reinfection and vaccination have positive correlations with the appearance of asymptomatic COVID-19 patients. In Cox proportional-hazards regression model, considering all clinical symptoms disappeared in 14 days as outcome, we found that ≤ 60 years old, male, no pre-existing conditions, vaccination and adopted treatment have positive correlations with rapid amelioration of clinical symptoms in COVID-19 patients. The clinical symptoms of the participants were mainly upper respiratory symptoms which were according with the infection of Omicron variant. Factors including age, gender, pre-existing conditions and reinfection could influence the clinical characteristics and prognosis of COVID-19 patients. Importantly, vaccination has positive significance for the prevention and treatment of COVID-19. Lastly, the use of Chinese medicine maybe beneficial to COVID-19 patients, however, reasonable guidance is necessary.

INTRODUCTION: Heterogeneous outcome reporting is common in clinical trials focused on cardiac rehabilitation for myocardial infarction (MI); this practice often results in the exclusion of data from clinical trials in systematic reviews. Developing a core outcome set (COS) may solve this problem. METHODS AND ANALYSIS: We will first identify a preliminary list of outcomes through a systematic review. Next, we will conduct semistructured interviews with patients to explore additional potential outcomes deemed important by patients. Then, we will engage various stakeholders such as clinicians, researchers and methodologists in two Delphi survey tends to refine and prioritise the identified outcomes. Subsequently, we will gather insights directly from patients with MI by administering plain language patient surveys; patients will be involved in questionnaire development. Finally, we will hold two face-to-face consensus meetings for patients and other stakeholders to develop the final COS for cardiac rehabilitation in MI. ETHICS AND DISSEMINATION: The Ethics Committee of Dongzhimen Hospital, Beijing University of Chinese Medicine approved this study (2022DZMEC-349). The final COS will be published in a peer-reviewed journal and disseminated in conferences. TRIAL REGISTRATION: We registered this study in the Core Outcome Measures in Effectiveness Trials Initiative (COMET) platform. REGISTRATION NUMBER: 1725 (http://www.comet-initiative.org/studies/details/1725).

OBJECTIVES: A core outcome set (COS) is an agreed standardized set of outcomes that should be measured and reported, as a minimum, in specific areas of health or health care. A COS is developed through a consensus process to ensure health care outcomes to be measured are relevant to decision-makers, including patients and health-care professionals. Use of COS in guideline development is likely to increase the relevance of the guideline to those decision-makers. Previous work has looked at the uptake of COS in trials, systematic reviews, health technology assessments and regulatory guidance but to date there has been no evaluation of the use of COS in practice guideline development. The objective of this study was to investigate the representation of core outcomes in a set of international practice guidelines. STUDY DESIGN AND SETTING: We searched for clinical guidelines relevant to ten high-quality COS (with focus on the United Kingdom, Germany, China, India, Canada, Denmark, United States and World Health Organisation). We matched scope between COS and guideline in terms of condition, population and outcome. We calculated the proportion of guidelines mentioning or referencing COS and the proportion of COS domains specifically, or generally, matching to outcomes specified in each guideline populations, interventions, comparators and outcome (PICO) statement. RESULTS: We found 38 guidelines that contained 170 PICO statements matching the scope of the ten COS and of sufficient quality to allow data extraction. None of the guidelines reviewed explicitly mentioned or referenced the relevant COS. The median (range) of the proportion of core outcomes covered either specifically or generally by the guideline PICO was 30% (0%-100%). CONCLUSION: There is no evidence that COS are being used routinely to inform the guideline development process, and concordance between outcomes in published guidelines and those in COS is limited. Further work is warranted to explore barriers and facilitators in the use of COS when developing clinical guidelines.

BACKGROUND: Clinical trials of traditional Chinese medicine (TCM) and Western medicine showed there was heterogeneity of outcome reporting in myocardial infarction (MI). Developing a core outcome set (COS) might improve the consistency of outcome reporting in future clinical trials. METHODS: A list of outcomes was developed based on a systematic review of randomized controlled trials (RCTs) of MI and semistructured interviews with MI patients. Two rounds of Delphi survey for clinicians, researchers, journal editors, and methodologists were conducted. An online questionnaire sent to nurses. After an online consensus meeting, a COS for MI RCTs was developed. RESULTS: After extracted data from clinical trials and discussed, 216 outcomes were included in round 1 of the Delphi survey. Seventy-four participants completed round 1 of the Delphi survey. Sixty-five participants completed round 2 of the Delphi survey. Twenty-two nurses completed the online questionnaire. Fifteen participants attended the online consensus meeting, and 14 of them voted and determined the final COS. For all types of MI, it was recommended that left ventricular ejection fraction and quality of life be measured and reported. For acute MI, the participants in the consensus meeting recommended the following core outcomes: death from cardio-cerebrovascular disease, cardiogenic shock, heart failure, troponin I, troponin T, creatine kinase isoenzyme, Killip class, target vessel revascularization, and emergency CABG. For previous MI, recurrent MI, recurrent angina pectoris, and heart failure readmission were recommended. CONCLUSIONS: The COS for MI in RCTs provides recommendations for clinical trials that seek to improve outcomes for patients with MI.

Liupao tea as a type of dark tea can relieve irritable bowel syndrome by regulating gut microbiota, but the mechanism has not been fully explained. An ultra-high performance liquid chromatography along with quadrupole time of flight tandem mass spectrometry was used to analyze the phytochemicals in Liupao tea. Then, we explored the effects of Liupao tea against IBS. From the results of chemical analysis, we identified catechins, polyphenols, amino acids, caffeine, polysaccharides and other components in Liupao tea. The open-field test, gastrointestinal function-related indexes, histochemical assays, measurements of cytokine and aquaporin 3 (AQP3), and determination of serum metabolites were utilized to monitor the physiological consequences of Liupao tea administration in rats with irritable bowel syndrome. The results showed that Liupao tea had a significant protective effect on irritable bowel syndrome. Liupao tea increased locomotive velocity while reducing interleukin-6, interleukin-1ß, and tumor necrosis factor-α levels, as well as gastrointestinal injury. Moreover, Liupao tea increased the AQP3 levels of renal tissues but reduced the AQP3 levels of gastrointestinal tissues. Liupao tea reduced the Firmicutes/Bacteroides ratio and significantly reconstructed the microbial pattern. Liupao tea relieved irritable bowel syndrome by repairing gastrointestinal dysfunction, regulating the secretion of pro-inflammatory cytokines, modulating water metabolism, and restoring microbial homeostasis.
ABSTRACT
Background: The concept of core outcome sets (COS) has been introduced in China for about 10 years. In recent years, some Chinese researchers also committed to developing COS, though the majority of COS are ongoing. However, there were more than 500 published COS for research in the COMET database by 2020. The extent of availability of COS for the top 25 diseases with the highest burden in China is unknown. In addition, the uptake of COS in clinical trials for these diseases is unknown, along with the knowledge, perceptions, and views of the clinical trialist community in China on the use of COS in relation to choosing outcomes for their research. Methods: The main burden of disease in China will be identified. Then we will search the COMET database to identify if there are ongoing or completed relevant COS research A COS published since 2012 would be preferred to one published before 2012 for the analysis of COS uptake if one meets the eligibility criteria. We will extract scopes of published eligible COS, including condition, population, interventions, and core outcomes. Then we will search the Chinese Clinical Trial Registry using disease names for each disease that has a published COS. We will assess the overlap in scope between clinical trials and COS. Then we will conduct an online survey and semi-structured interviews to identify the knowledge and perceptions of COS among primary investigators of included clinical trials. Discussion: This research will fill in gaps between COS and the burden of disease in China. Understanding clinical trialists'knowledge and perceptions of COS may help dissemination and application of COS in the future. Trial registration: This research is registered in Core Outcome Measures in Effectiveness: https://www.comet-initiative.org/Studies/Details/2563.

BACKGROUNDS: Traditional Chinese medicine and Western medicine combination (TCM-WMC) increased the complexity of compounds ingested. OBJECTIVE: To develop a method for screening hepatotoxic compounds in TCM-WMC based on chemical structures using artificial intelligence (AI) methods. METHODS: Drug-induced liver injury (DILI) data was collected from the public databases and published literatures. The total dataset formed by DILI data was randomly divided into training set and test set at a ratio of 3:1 approximately. Machine learning models of SGD (Stochastic Gradient Descent), kNN (k-Nearest Neighbor), SVM (Support Vector Machine), NB (Naive Bayes), DT (Decision Tree), RF (Random Forest), ANN (Artificial Neural Network), AdaBoost, LR (Logistic Regression) and one deep learning model (deep belief network, DBN) were adopted to construct models for screening hepatotoxic compounds. RESULT: Dataset of 2035 hepatotoxic compounds was collected in this research, in which 1505 compounds were as training set and 530 compounds were as test set. Results showed that RF obtained 0.838 of classification accuracy (CA), 0.827 of F1-score, 0.832 of Precision, 0.838 of Recall, 0.814 of area under the curve (AUC) on the training set and 0.767 of CA, 0.731 of F1, 0.739 of Precision, 0.767 of Recall, 0.739 of AUC on the test set, which was better than other eight machine learning methods. The DBN obtained 82.2% accuracy on the test set, which was higher than any other machine learning models on the test set. CONCLUSION: The DILI AI models were expected to effectively screen hepatotoxic compounds in TCM-WMC.
ABSTRACT
BACKGROUND: Integrative medicine is commonly used in China. Researchers prefer to report efficacy outcomes rather than safety outcomes in clinical trials; thus, evidence regarding safety in integrative medicine is unclear. Developing a core outcome set (COS) for safety outcomes is necessary. In this study, a representative example of the methodology for developing COS to assess safety outcomes of cardiovascular diseases in clinical trials investigating integrated medicine will be developed. METHODS AND ANALYSIS: Safety information will be extracted from package inserts and through systematic reviews of treatments for cardiovascular diseases (including angina pectoris, myocardial infarction, heart failure, arrhythmia, and hypertension) to develop an extensive list of safety outcomes, which will then be categorized according to whether subjective or objective outcomes. Questionnaires for clinician-reported safety outcomes and patient-reported safety outcomes will be developed. Two rounds of the Delphi survey will then be conducted for different stakeholders (traditional Chinese medicine clinicians and researchers in cardiovascular diseases, Western medicine clinicians and researchers in cardiovascular diseases, integrated medicine clinicians and researchers of cardiovascular diseases, pharmacologists, methodologists of evidence-based medicine, and patients). After round 2 of the Delphi analysis, a face-to-face consensus meeting will be held to determine the final COS for assessing safety outcomes in cardiovascular diseases. DISCUSSION: A COS for safety outcomes in cardiovascular diseases may improve the consistency of reporting results and will help identify potential bias of selective reporting in the future. TRIAL REGISTRATION: This study was registered in the Core Outcome Measures in Effectiveness Trials database as study 1564 .

ETHNOPHARMACOLOGICAL RELEVANCE: In China, Xiyanping (XYP) has been widely used in combination with Ribavirin (RB) for the treatment of infectious diseases. It has been found that this combination may change the severity of XYP-associated adverse events (AEs). AIM: To provide a comprehensive review about the clinal features of AEs of XYP-RB combination from randomized controlled trials, cohort studies, case-control studies, case reports, case series, and data from the National Adverse Drug Reaction Monitoring Information System (NADRMIS). MATERIALS AND METHODS: Seven electronic databases were searched in March 2021. Articles on AEs associated with XYP published from January 2004 to December 2020 in the NADRMIS were included. Data on the incidence of AEs, distribution of AEs, occurrence time of AEs, type and possible signal of AEs, primary diseases, allergic history, family history of allergies, dosage, and combination interval were extracted. RESULTS: We included 228 cases of AEs with XYP-RB combination (63 cases from randomized controlled trials, 1 from a cohort study, and 164 from the NADRMIS). The most common primary disease was hand-foot-and-mouth disease. The main age distribution was 0-6 years (118 cases, 72%) and 8 cases (6.8%) experienced serious AEs. The combination group showed a significant reduction than the RB group in the incidence of AEs in those with hand-foot-and-mouth disease (risk ratio = 0.54, 95% confidence interval = 0.38-0.78, P = 0.0008) and children with viral pneumonia (risk ratio = 0.36, 95% confidence interval = 0.14-0.95, P = 0.04). Allergic history and infusion interval were not described in the randomized controlled trials. AEs were reported in 57.9% of cases in the first combination (XYP-RB were combined for the first time) (NADRMIS), 56.4% of which were skin and appendage reactions, and the risk signal of skin and appendage reactions was a maximum (Information Component = 6.21). CONCLUSION: The major AE associated with XYP-RB combination was skin and appendage reactions. Most of the combination AEs were pseudo-allergic reactions. These findings suggest that we should increase awareness about the safety of XYP-RB combination treatment and standardize medication protocol, especially for children. Unless absolutely necessary, children should avoid combination therapy. More rigorous high-quality studies are needed to obtain more evidence.

It was pointed out in Opinions on Promoting the Inheritance, Innovation and Development of Traditional Chinese Medicine issued by the State Council in 2019 that 100 varieties of traditional Chinese medicine(TCM) with unique curative effects should be screened out within about three years. Due to the multi-component and multi-target mechanisms of TCM varieties, it is difficult to directly and simply evaluate their multi-dimensional clinical value using methods applicable to chemical or biological agents. The heterogeneity of outcomes for similar TCM makes it difficult to determine the advantages of similar products. The fuzzy comprehensive evaluation method that is developed on the basis of core outcome set and fuzzy mathematics for clinical efficacy evaluation of TCM may solve these problems. This study developed a fuzzy comprehensive evaluation model for the clinical efficacy evaluation of Chinese patent me-dicines for coronary heart disease and angina pectoris, and selected the previous normative studies with complete or incomplete data for verifying the model application. The results showed that original studies with complete data failed to evaluate and compare the comprehensive efficacy of different interventions. The original research only mentioned the advantages and disadvantages of different interventions in different aspects. The comprehensive clinical efficacy of three different interventions obtained through fuzzy comprehensive evaluation was all graded as level â ¡. The original research with incomplete data drew the same conclusions as the fuzzy comprehensive evaluation, and the results of fuzzy comprehensive evaluation can provide more comprehensive information. Therefore, the fuzzy comprehensive evaluation shows the products with overall advantages of clinical efficacy, which may become a feasible method for the screening of TCM.

Drug-induced liver injury (DILI) has always been the focus of clinicians and drug researchers. How to improve the performance of the DILI prediction model to accurately predict liver injury was an urgent problem for researchers in the field of medical research. In order to solve this scientific problem, this research collected a comprehensive and accurate dataset of DILI with high recognition and high quality based on clinically confirmed DILI compound datasets, including 1446 chemical compounds. Then, the residual neural network with 18-layer by using more 5-layer blocks (ResNet18) with deep neural network (ResNet18DNN) model was proposed to predict DILI, which was an improved model for DILI prediction through vectorization of compound structure image. In predicting DILI, the ResNet18DNN learned greatly and outperformed the existing state-of-the-art DILI predictors. The results of DILI prediction model based on ResNet18DNN showed that the AUC (area under the curve), accuracy, recall, precision, F1-score and specificity of the training set were 0.973, 0.992, 0.995, 0.994, 0.995 and 0.975; those of test set were, respectively, 0.958, 0.976, 0.935, 0.947, 0.926 and 0.913, which were better than the performance of previously published described DILI prediction models. This method adopted ResNet18 embedding method to vectorize molecular structure images and the evaluation indicators of Resnet18DNN were obtained after 10 000 iterations. This prediction approach will greatly improve the performance of the predictive model of DILI and provide an accurate and precise early warning method for DILI in drug development and clinical medication.

Depression is associated with poorer outcomes in a wide spectrum of surgeries but the specific effects of depression in patients undergoing cervical spine surgery are unknown. This study aimed to evaluate the prevalence and impact of pre-surgical clinical depression on pain and other outcomes after surgery for cervical degenerative disc disease using a national representative database. Data of patients with cervical myelopathy and radiculopathy were extracted from the 2005-2014 US Nationwide Inpatient Sample (NIS) database. Included patients underwent anterior discectomy and fusion (ACDF). Acute or chronic post-surgical pain, postoperative complications, unfavorable discharge, length of stay (LOS) and hospital costs were evaluated. Totally 215,684 patients were included. Pre-surgical depression was found in 29,889 (13.86%) patients, with a prevalence nearly doubled during 2005-2014 in the US. Depression was independently associated with acute or chronic post-surgical pain (aOR: 1.432), unfavorable discharge (aOR: 1.311), prolonged LOS (aOR: 1.152), any complication (aOR: 1.232), respiratory complications/pneumonia (aOR: 1.153), dysphagia (aOR: 1.105), bleeding (aOR: 1.085), infection/sepsis (aOR: 1.529), and higher hospital costs (beta: 1080.640) compared to non-depression. No significant risk of delirium or venous thrombotic events was observed in patients with depression as compared to non-depression. Among patients receiving primary surgery, depression was independently associated with prolonged LOS (aOR: 1.150), any complication (aOR:1.233) and postoperative pain (aOR:1.927). In revision surgery, no significant associations were found for prolonged LOS, any complication or pain. In conclusion, in the US patients undergoing ACDF, pre-surgical clinical depression predicts post-surgical acute or chronic pain, a slightly prolonged LOS and the presence of any complication. Awareness of these associations may help clinicians stratify risk preoperatively and optimize patient care.

BACKGROUND: Traditional Chinese medicine (TCM) may improve the prognosis management of cholelithiasis patients after gallbladder-preserving lithotripsy. To explore the evidence for this view, we systematically reviewed the efficacy and safety of TCM for improving the prognosis of cholelithiasis after gallbladder-preserving lithotripsy and performed functional pathway enrichment analysis of TCM target genes. METHODS: In this systematic review (SRs), we searched six Chinese or international databases to collect randomized controlled clinical trials (RCTs) of TCM in preventing the recurrence of cholelithiasis after gallbladder-preserving lithotripsy. The literature was independently screened by 2 reviewers, who then extracted the data. The Cochrane risk-of-bias and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tools were used to assess the included studies' risk of bias and quality of evidence, respectively. And, the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses would be conducted on the TCM prescriptions in the included literature to find the effective component and mechanism of TCM in the prognosis management of gallbladder-preserving lithotripsy. Analysis in this research would be conducted by R 3.5.2 software. RESULTS: A total of 1,024 articles were retrieved, and 9 RCTs involving 926 participants were included after the step-by-step screening. The risk of bias for each important outcome in all the studies was "uncertain". The meta-analysis showed that compared with blank control, TCM prevented cholelithiasis by decreasing the recurrence rate, complications incidence, gallbladder wall thickness, and gallbladder contraction degree. But, there were no significant differences in the rate of the adverse reaction. The result of the GO and KEGG analysis revealed that the mechanism of prevention of TCM in gallstone recurrence may be related to the cholesterol metabolic pathway and that naringin from Glycyrrhiza may be the effective component in the prevention of recurrence. CONCLUSIONS: Existing evidence suggests that the use of TCM may reduce the recurrence rate after gallbladder-preserving lithotripsy and this effect may be related to the flavonoid glycoside naringin from Glycyrrhiza uralensis, but more RCTs with high quality in this area may be needed to have a robust conclusion.

BACKGROUND: Traditional Chinese medicine (TCM) has gained widespread application in treating chronic heart failure (CHF) secondary to coronary heart disease (CHD). However, the sound clinical evidence is still lacking. Corresponding clinical trials vary considerably in the outcome measures assessing the efficacy of TCM, some that showed the improvement of clinical symptoms are not universally acknowledged. Rational outcome measures are the key to evaluate efficacy and safety of each treatment and significant elements of a convincing clinical trial. We aimed to summarize and analyze outcome measures in randomized controlled trials (RCTs) of TCM in treating CHF caused by CHD, subsequently identify the present problems and try to put forward solutions. METHODS: We systematically searched databases including Embase, PubMed, Cochrane Library, CBM, CNKI, VIP and Wanfang from inception to October 8, 2018, to identify eligible RCTs using TCM interventions for treating CHF patients caused by CHD. Cochrane Database of Systematic Reviews (CDSR) was searched to include Cochrane systematic reviews (CSRs) of CHF. Two authors independently assessed the risk of bias of the included RCTs according to the Cochrane Handbook. Outcome measures of each trial were extracted and analyzed those compared with the CSRs. We also evaluated the reporting quality of the outcome measures. RESULTS: A total of 31 RCTs were included and the methodology quality of the studies was generally low. Outcome measures in these RCTs were mortality, rehospitalization, efficacy of cardiac function, left ventricular ejection fraction (LVEF), 6 min' walk distance (6MWD) and Brain natriuretic peptide (BNP), of which mortality and rehospitalization are clinical end points while the others are surrogate outcomes. The reporting rate of mortality and rehospitalization was 12.90% (4/31), the other included studies reported surrogate outcomes. As safety measure, 54.84% of the studies reported adverse drug reactions. Two trials were evaluated as high in reporting quality of outcomes and that of the other 29 studies was poor due to lack of necessary information for reporting. CONCLUSIONS: The present RCTs of TCM in treating CHF secondary to CHD did not concentrate on the clinical end points of heart failure, which were generally small in size and short in duration. Moreover, these trials lacked adequate safety evaluation, had low quality in reporting outcomes and certain risk of bias in methodology. For objective assessment of the efficacy and safety of TCM in treating CHF secondary to CHD, future research should be rigorous designed, set end points as primary outcome measures and pay more attention to safety evaluation throughout the trial.

Clinical trial outcome reporting differs between studies integrating traditional Chinese medicine (TCM) and Western medicine, so that some clinical trials are not eligible for inclusion in a systematic review. The excluded studies are therefore less widely disseminated, and even valid studies are less likely to yield impact. This problem may be addressed by developing core outcome sets (COSs) for integrative medicine in specific healthcare areas. The first stage of development is to define the scope of the COS for integrative medicine, the second stage is to establish the need for such a COS, and the third stage is to develop a protocol and register the COS. The final stage involves three steps: (i) development of a comprehensive list of outcomes (including efficacy outcomes and safety outcomes and TCM syndromes) using systematic review, qualitative or cross-sectional research, and reviews of package inserts and medical records; (ii) merging and grouping of outcomes within domains; (iii) conducting two rounds of Delphi survey and consensus meetings with a range of stakeholders. The final COS will include a general COS and core TCM syndrome- set. Development of COSs for clinical trials of integrative medicine may help to standardize outcome reporting and reduce publication bias in the future.

BACKGROUND: Acupuncture is considered a complementary therapy for atopic eczema. The aim of this scoping review is to identify, examine, and summarize the potential acupoint prescriptions and outcome reporting regarding the clinical trials of acupuncture for eczema. METHODS: We searched different databases from inception to September 30, 2020. The data were screened and extracted to identify the potential acupuncture prescription and examine the variation in outcome reporting, outcome measurement instruments (OMIs), and measurement time points in clinical trials of acupuncture. RESULTS: A total of 116 clinical studies were included. The acupoint combination of LI11 and SP10 was used frequently. The core acupoint association networks were acupoints LI11, SP10, ST36, SP6, and LI4. For clinical trials of acupuncture, a total of 6 outcome distinct domains were identified in the 32 outcome measurements. The most frequently reported outcome was the eczema area, which was reported 97 times (83.6%, 97/116). Immune system outcomes were assessed in 15 outcome measurements, which totally reported 37 times. Adverse events were reported 51 times. TCM syndrome, which could reflect the characteristics of TCM, was reported 4 times. 29 outcomes (90.6%, 29/32) were provided definitions or OMIs. Among these outcomes, the outcome measurement times ranged from 0 to 34. CONCLUSIONS: This scoping review provides potential knowledge that should be considered as priority in future research of acupuncture for eczema.
ABSTRACT
Aims: To identify a minimum set of efficacy and adverse events for patients with acute heart failure (AHF) among different stakeholders in clinical trials of traditional Chinese medicine and Western medicine. Methods and Analysis: First, we will develop a preliminary long list of outcomes that includes efficacy and adverse events/reactions via three steps: (i) systematic reviews of efficacy and safety outcomes for clinical trials of AHF; (ii) drugs included in the National Medical Insurance Catalog, the National Essential Medicines Catalog, and the WHO Essential Medicines List will be collected and safety outcomes extracted from the package inserts; and (iii) patients' or caregivers' semi-structured interviews will be carried out to add new viewpoints to the list. Second, after merging outcomes and grouping them under different outcome domains, questionnaires for health professionals and patients will be separately developed. Further, two rounds of Delphi survey for health professionals and a survey for patients and the public will be carried out. Third, different stakeholders will discuss and determine the final core outcome set (COS) for AHF in a consensus meeting. Ethics and Dissemination: The entire project has been approved by the Ethics Committee of the main institution. After the final COS is developed, it will be published and discussed widely in conferences. Clinical Trial Registration: This study is registered with the Core Outcome Measures in Effectiveness Trials database as study 1566 (available at: https://www.cometinitiative.org/Studies/Details/1566).
ABSTRACT
ETHNOPHARMACOLOGICAL RELEVANCE: Fangji is an ancient combinatorial formula. The compatibility mechanisms that how component herbs of Fangji work cooperatively to achieve the executive framework remain unexplored. AIM OF THE STUDY: Toexplore compatibility mechanism and systematical effects of Fangjis by taking Wenxin Keli decoction (WXKL), a classical Fangji constituted by Codonopsis Radix, PolygonatiRhizoma, Notoginseng Radix Et Rhizoma, Ambrum, and Nardostachyos Radix Et Rhizoma., as example. MAIN METHODS: Here, we employed bioinformatics approach, including cluster analysis, cooperative module pair analysis, primary module identification, and proximity examination among target profile of herbs, to investigate compatibility characterization and anti-arrhythmia mechanism of WXKL. Finally, core mechanisms of WXKL were validatedby in vivo experiments. RESULTS: As a result, we identified 695 putative target proteins and 27 clusters (W-modules) inWXKL target network (W-network), in which W-module 1, 2, 4, 8, 10 were primary modules. The cooperative module pairs were W-module 2 and 4, W-module 2 and 8, and W-module 2 and 1, all of which existed in Codonopsis Radix- or Notoginseng Radix Et Rhizoma.-condition. And Nardostachyos Radix Et Rhizoma only yielded cooperation between W-module 1 and 2. The proximity of herbs' target profiles of Codonopsis Radix and Notoginseng Radix Et Rhizoma were similar, and Nardostachyos Radix Et Rhizoma and Ambrum were similar. For the compatibility framework, Codonopsis Radix general regulated 70.67% targets and majority W-modules (81.48%) as sovereign herb, contributing to primary therapeutic effect, mainly involving neurohormonal regulation, vasomotor, inflammation and oxidative stress. Other herbs assisted Codonopsis Radix to enhance major outcomes through common modules, and acted as complementary roles through unique process including mitotic cell cycle, biosynthetic and catabolic process, etc. Furthermore, WXKL regulated 66.67% hub proteins of arrhythmia-network, 68.18% and 47.37% proteins in primary arrhythmia-module 1 and 2, mainly involving ion channel activity, neurohormonal regulation, and stress response processes, to constitute regulatory network focusing on cardiovascular, renal, nervous system, to reverse the pathological process of arrhythmia. In vivo experiments demonstrated WXKL can attenuate adrenergic activation induced sympathetic atrial fibrillation by inhibiting calmodulin expression (CaM) and ryanodine receptor 2 (RYR2) phosphorylation to regulate neurohormonal action. CONCLUSION: This strategy provided an overarching view of anti-arrhythmia mechanism of WXKL and its internal compatibility, and may facilitate the understanding of compatibility in Fangjis from the perspectives of modern biology.
