Evidence-Based Evaluation of Vitamin C and D in the Treatment and Prevention of Acute Viral Respiratory Infectious Disease / 中国药学杂志

OBJECTIVE: To evaluate the evidence supporting vitamin C and D medication in the treatment and prevention of acute viral respiratory infectious disease, and to provide evidence for clinical rational medication and potential treatment option for COVID-19 especially. METHODS: PubMed database was retrieved from inception to February 13, 2020, and the references in the reviews and those not included in the database were manually retrieved. RESULTS: Eight literatures were included finally. In terms of COVID-19, MERS, and SARS, none literature about vitamin C and D medication was available. In terms of influenza, one prospective controlled trial proved vitamin C's efficacy. For vitamin D in influenza, one systematic review and one randomized controlled trial proved its efficacy, while three randomized controlled trials showed no efficacy. Additionally, one case-control study showed no statistical association between vitamin D level and the risk of influenza, and one randomized controlled trial showed no significant difference between high-dose and standard-dose vitamin D supplementation. CONCLUSION: Currently, no evidence supports the effectiveness of vitamin C and D medication in the prevention and treatment of COVID-19, MERS and SARS. However, limited evidence supports potential benefit of vitamin C and D medication in influenza. Physicians and pharmacists should take relevant clinical practice guidelines and supporting evidence into consideration when using vitamin C or D (especially high-dose medication), and pay attention to monitoring drug adverse reactions and drug interactions.

Evidence-based Evaluation on the Current Status of Global Antibacterial Use Surveillance / 中国药房

OBJECTIVE:To provide evidence-based basis for the continuous improvement of antibacterial use surveillance in China.METHODS:Retrieving from 3 biomedical literature databases as Medline,Embase,Cochrane Library,48 health administrative departments and academic institutions,relevant literatures on antibacterial surveillance networks/ projects were acquired and extracted,including basic information,data collection,analysis and reporting methods,etc.Descriptive analysis method was adopted to analyze the status quo of global antibacterial surveillance networks/projects.RESULTS:A total of 21 literatures were included,involving 16 antibacterial surveillance networks/projects.Among them,there were 3 international projects and 13 national projects,mainly in European (countries) (56.25％,9/16).Sixteen antibacterial surveillance networks/projects were established to monitor and compare the use of antibacterials,analyze the antibacterial use trend and its correlation with bacterial resistance,and evaluate implementation effect of antibacterial management policy.The responsible agencies were mainly the health administrative departments,and the funding agencies were mainly related government departments.Hospital and community were main surveillance objects.There were 2 surveillance networks/projects for antibacterial use in children,and 6 surveillance networks/projects contained medication data of children.Only Strama in Sweden alone analyzed medication data in children.Fourteen surveillance networks/projects promulgated data collection methods or contents;data collection was mainly based on active reporting and involved the data of drug use/consumption and population/ patient.Except for ESAC-Net,ARPEC,NAUSP,data validation method was not mentioned in other surveillance networks/projects.Data analysis was most common in medical institutions and antibacterial categories,and defined daily dose was the most commonly used statistical indicators of antibacterial consumption.Ten surveillance networks/projects promulgated surveillance reports which were mostly published annually.CONCLUSIONS:Antibacterial surveillance have been widely operated worldwide.But there is a lack of monitoring and analysis of antibacterial use in special population including children.In addition,data validation is the weak link of antibacterial surveillance,so the quality of data collection still need to be improved.

Evidence-based Chinese medicine：theory and practice / 中国中药杂志

The introduction and popularization of evidence-based medicine has opened up a new research field of clinical efficacy evaluation of traditional Chinese medicine(TCM), produced new research ideas and methods, and promoted the progress of clinical research of TCM. After about 20 years assiduous study and earnest practice, the evidence based evaluation method and technique, which conforms to the characteristics of TCM theory and practice, has been developing continuously. Evidence-based Chinese medicine (EBCM) has gradually formed and become an important branch of evidence-based medicine. The basic concept of evidence-based Chinese medicine: EBCM is an applied discipline, following the theory and methodology of evidence-based medicine, to collect, evaluate, produce, transform the evidence of effectiveness, safety and economy of TCM, to reveal the feature and regular pattern of TCM taking effect, and to guide the development of clinical guidelines, clinical pathways and health decisions. The effects and achievements of EBCM development: secondary studies mainly based on systematic review/Meta-analysis were extensively carried out; clinical efficacy studies mainly relying on randomized controlled trials grew rapidly; clinical safety evaluations based on real world study have been conducted; methodological researches mainly focused on study quality control deepened gradually; internationalization researches mainly on report specifications have got some breakthroughs; standardization researches based on treatment specification were strengthened gradually; the research team and talents with the characteristics of inter-disciplinary have been steadily increased. A number of high-quality research findings have been published at international well-known journals; the clinical efficacy and safety evidence of TCM has been increased; the level of clinical rational use of TCM has been improved; a large number of Chinese patent medicines with big market have been cultured. The future missions of EBCM mainly consist of four categories (scientific research, methodology and standard, platform construction and personnel training) with nine tasks. ①Carry out systematic reviews to systematically collect clinical trial reports of TCM and establish database of clinical evidence of TCM; ②Carry out evidence transformation research to lay the foundation for the development of clinical diagnosis and treatment guidelines, clinical pathways of TCM, and for the screening of basic drug list and medical insurance list, and for the policy-making relevant to TCM; ③Conduct researches to evaluate the advantages and effective regular patterns of TCM and form the evidence chain of TCM efficacy; ④Carry out researches for the safety evaluation of TCM, and provide evidence supporting the rational and safe use of TCM in clinical practice; ⑤Conduct researches on methodology of EBCM and provide method for developing high quality evidence; ⑥Carry out researches to develop standards and norms of TCM, and to form methods, standards, specifications and technical systems; ⑦Establish data management platform for evidence-based evaluation of TCM, and promote data sharing; ⑧Build international academic exchange platform to promote international cooperation and mutual recognition of EBCM research; ⑨Carry out education and popularization activities of evidence-based evaluation methods, and train undergraduate students, graduate students, clinical healthcare providers and practitioners of TCM. The development of EBCM, as it was, not only promoted the transformation of clinical research and decision-making mode of TCM, contributed to the modernization and internationalization of TCM, but also enriched the connotation of Evidence-based Medicine.

Evidence-based evaluation of Chinese students' social practice and guarantee mechanism / 中华医学教育探索杂志

Objective To investigate and analyze the researches and guarantee mechanisms of Chinese undergraduate students' social practice, to understand the current situation of college students' social practice and research quality and to provide the reference for the development of college students' social practice guarantee mechanism in China. Methods With the “University” “college students”“social practice” as key words , we retrieved published documents about long-term mechanism of CUSSP dating to March 2014, from Chinese journal full text database(CNKI), China outstanding master's degree thesis database, Chinese Excellent Doctor Degree Dissertation Full-text Database, Wanfang, CMFD, CDFD,VIP, Google and Baidu, etc. We classified the including documents based on evidence-based scientific evidence grading standards, analyzed Grade C and above documents only. Results A total of 22 relevant studies were included; 4 of them are policy studies with Grade B, 18 of them are cross-sectional studies with grade C. The studies showed: ①The policy studies give important sugges-tions on the content, form, effect, construction and evaluation system of long-term mechanism of CUSSP.②18 cross-sectional studies surveyed over 14 504 students' social practice conditions show the method-ology of most of the studies is described unclearly or non-standard however. ③12 studies have inves-tigated the Chinese college students' attitude towards social practice and actual participation, with 5 studies about the time of participation and 5 about the condition of combination with specialty. The undergraduate students can recognize the importance of social practice, however, the range, duration and times of their actual participation are limited, and the combination with their major is not close enough. ④7 studies have investigated the main problems of college students' social practice and 5 studies have investigated the students' satisfaction. At present, there exist many problems in CUSSP, of which the most difficult things are: hard-to-contacting practice units, lack of funds, lack of teacher guidance, hard-to-determining the practical projects etc. The students' overall satisfaction is“general”. Conclusions ①There is lack of high-quality studies about CUSSP, and the methodology of studies should be improved and standardized. ②Strengthening the long-term mechanism and evaluation system construction is urgently needed to ensure that students can conduct long-term, effective and stable social practice.
