Objectives To analyze the effect of improved oven for defluorination in coal-burning endemic fluorosis areas in China, and to provide evidence for the prevention and control of fluorosis. Methods Electronic databases including CNKI, CBM, VIP and CDMD-D (1989 to 2005), were searched. We also checked the reference lists of relevant articles. We selected relevant articles according to the predefined inclusion and exclusion criteria. The methodological quality was assessed . Data on room heat preservation and the effect of improved oven for defluorination were collected in the surveillance spots of Three Gorges Reservoir. Correlation analyses were conducted between the improved oven and its effect parameters. Results Twelve articles of low quality met the selection criteria, of which 9 were graded C and 3 were graded D in terms of the methodological quality. A negative correlation was found between the decreasing rate of normal oven use and the decreasing rate of dental fluorosis as well as of urine fluorine (Pearson correlation coefficient r = – 0.87, – 0.63, Plt;0.01, lt;0.05, respectively). Analysis also revealed a positive correlation between room heat preservation and the decreasing rate of dental fluorosis as well as of normal oven use (the two Spearman correlation coefficients and P values were the same: r = –1.00, Plt;0.01). Conclusion High-quality studies on the effect of improved oven for defluorination in China are not available. Based on the current evidence, the improved oven for defluorination and the correct use, maintenance and house rebuilding for heat preservation may help to prevent fluorosis.
Based on the site visit on the current application and practice of evidence-based medicine in USA, we find the difference between China and USA so as to further promote and plan the development of evidence-based medicine in China.
Gout is caused by abnormal metabolism of purine. Its most common symptom attack of intense pain and swelling in the joints. Attacks of gout can according to the alteration if it is in acute interval periods. How can we get the optimal effect? The development of methodology has provided much convincing evidence for us to choose the most appropriate treatment.
Liver cancer is one of the world’s most prevalent malignancies, and is also the third leading cause of cancer death in China. Hepatitis and cirrhosis background is a major feature of liver cancer patients in China, which makes specific requirements that suits the national conditions in many aspects of prevention and control like screening diagnosis, treatment options, and prognosis follow-up. The Specifications for Diagnosis and Treatment of Primary Liver Cancer (2017 Edition), which is based on China’s practice, proposes liver cancer staging in line with China’s national conditions and forms a multi-disciplinary joint diagnosis and treatment model based on surgical treatment. Liver transplantation is included in liver cancer as one of the surgical treatments option. It also emphasizes the support of evidence-based medicine. The Specifications for Diagnosis and Treatment of Primary Liver Cancer (2017 Edition) may have laid a solid foundation for future diagnosis and treatment of liver cancer in China.
Objective The purpose of this study, which focuses on the number of the Cochrane Systematic Review’s (CSR) full texts, protocols and registered titles from Chinese authors, is to show the development of evidence-based medicine (EBM) and promote EBM’s further development in China. Methods On the basis of The Cochrane Library (Issue 1, 2009) and the Cochrane Collaboration (March 2009) periodicals, we performed statistical analysis of different countries that released CSR’s full texts, protocols and registered titles, as well as the time, authors and distribution of the CSR’s full texts, protocols and registered titles in China. Results The publishing rates of the CSR’s full texts, protocols and registered titles in China ranked the seventh, fifth and second, respectively. Although the number of CSR’s full texts and protocols showed an increased annual trend in China, the development of area distribution was unbalanced. Moreover, China’s published articles contained 47 Cochrane collaboration groups, without effective practice and health care groups, consumers and communication groups, and methodology and multiple stenosis groups. Conclusions The current Chinese EBM situation has a great potential in writing CSR. However, there are still many problems that need to be resolved.
