OBJECTIVEThe aim of this study is to investigate the occurrence and mechanism of Cheyne-Stokes breathing pattern in patients with heart failure.

METHODSFifty-six patients who performed polusomnography sleep testing at National Center of Cardiovascular Diseases Fuwai Hospital from March to May in 2015. We divided them into chronic heart failure (CHF) group and non-CHF group.

RESULTSThe occurrences of sleep apnea in two groups were high. In CHF group (n = 11) , there were 10 patients with apnea hypopnea index (AHI) > 5; and their AHI was 23.93 ±14.63. In non-CHF group (n = 45), there were 33 patients whose AHI > 5; and their AHI was 16.20 ± 18.76. The ratio of center sleep apnea to all gross sleep apnea ratio in CHF group was higher than that in non-CHF group (80.21% ± 30.55% vs 27.16% ± 35.71%, P < 0.01 ).

CONCLUSIONBased upon the new theory of holistic integrative physiology and medicine, we explain the mechanism of circulatory dysfunction induce the oscillation breathing in patients with CHF. The sleep apnea and C-S respiration in CHF should be called circulatory sleep apnea, rather than central sleep apnea.

Objective To analyze the characteristics of published radiology original articles in China,and compare radiology research inboard and abroad.Methods According to the Contents of Chinese Science Core Periodicals in 2012,there were 15 comprehensive radiological core periodicals in China.All of them were retrospectively surveyed,and original articles published between October 2011 and October 2012were evaluated.The following information was abstracted from each article:radiologic technique used,radiologic subspeciahy,type of research,sample size and study design.At the same time,all the original articles from two top radiology journals,Radiology and European Radiology (ER) at the same period were evaluated.Chi-square test was used to compare the composition percentage inboard and abroad.Results There were 2784 original articles published in the 15 Chinese top radiological periodicals in total The most commonly used radiologic techniques were CT (1093 of 2784,39.3％),MRI (824 of 2784,29.6％) and intervention (402 of 2784,14.4％).Radiology and ER totally published 560 original articles.MRI (265 of 560,47.3％),CT (170 of 560,30.4％) and mixed techniques (63 of 560,11.3％) were most used.In China,as much as 2572 (92.4％) articles were clinical research,115 (4.1％) was basic research,9 (0.3％) was clinical and basic research,and 83 (3.2％) was non-basic non-clinical research.The sample size of less than 10,between 10 to 50,and more than 50 was 374 (13.4％),1448 (52.0％) and 847 (30.4％) respectively.339 (12.2％) Chinese articles belonged to perspective research,and 1211 (43.5％) were retrospective.For Radiology and ER,515 (92.0％) articles were clinical research,39 (7.0％) was basic research,3(0.5％) was clinical and basic research,and 3(0.5％) was non-basic non-clinical.The sample size of less than I0,between 10 to 50,and more than 50 was 30 (5.4％),225 (40.2％) and 252 (45.0％) respectively.230 (41.1％) articles belonged to perspective research,and 202 (36.1％) ones were retrospective.Radiology and ER articles used MRI more than that published in Chinese radiology journals (x2 =666.690,P ＜ 0.01).Clinical research was the most commonly used research type both inboard and abroad (x2 =0.116,P ＞0.05).Articles of sample size more than 50 abroad were more than that of China (x2 =44.895,P ＜0.01).Perspective research was used more abroad (x2 =275.667,P ＜ 0.01),and the main research type in China was retrospective.Conclusion Chinese radiology workers might need to do more perspective and larger sample size clinical researches.

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.

The specification of decoction pieces and quality uniformity are the important factors to influence the efficacy of clinical medicine. Considering the deficiency of diversity, poor quality uniformity and confusion of decoction pieces specifications, we first propose a new idea of precision decoction pieces (PDP) based on clinical demands and fresh-processed technology. In order to explain the idea, a study case of aconite SUP is provided, including the optimized specification design, processing technology, extraction effects, quality uniformity, and toxic and efficacy variation and so on. The results showed that preparing 5 mm PDP by fresh-cutting is rather simple and practicable, with high efficiency and large yield; then, this technology could significantly decrease the ingredients loss and increase the efficacy components; moreover, it was helpful for achieving the quality uniformity and best extraction effects. This work revealed the quality superiority of PDP, and provided a good strategy and example for the standard of decoction pieces specification and modernization of processing technology.

Objective To analyze the data of road traffic accidents, deaths and injuries in 31 provinces and municipalities in China from 2010 to 2017, and to predict that the number of deaths and injuries caused by road accidents set in the sustainable development goals (SDGs) will be halved by 2020 compared with the target set in 2015. Methods Describing and analyzing the current situation of road traffic accidents in 31 provinces and municipalities in China, and using the trend extrapolation method to predict whether the SDGs target can be achieved by 2020. Results The numbers of traffic accidents, deaths and injuries in Guangdong, Jiangsu, Zhejiang and Shandong Provinces showed a downward trend from 2010 to 2017, but still ranked the front in China. In 2017, Beijing had the highest death rate followed by Guizhou as the second, and Guizhou had the highest injury rate followed by Tianjin as the second. The projected results showed that the numbers of deaths and injuries caused by road traffic accidents in China would be increased by 17% and 1.3% respectively in 2020 indicating that SDGs target could not be met. Among the 31 provinces/municipalities, it was predicted that the numbers of deaths and injuries in Hunan would be reduced to 50.7% and 65.3% in 2015, respectively by 2020, and the target could be achieved; the number of injuries in Shanghai was decreased by 83.3%, but the deaths was only decreased by 34.5%, and there was still a gap with the target; the rest 29 provinces/municipalities could not meet SDGs target. It was expected that the deaths in 11 provinces and municipalities would increase by 2020, with Beijing, Jilin, Jiangxi, Hubei and Guizhou Provinces showing the most significant growth. The number of injured people in 8 provinces and municipalities shows an increasing trend, with Jilin, Jiangxi, Hubei and Guizhou provinces showing significant growth. Conclusions Except for Hunan Province, it was difficult for the whole country and the rest provinces and municipalities to reach the SDGs target. According to the forecast results and the actual situation, a targeted scientific prevention and control strategy can be formulated. The measures taken by Hunan and Shanghai in traffic accident prevention and control were effective and worth learning.
