Objective: To observe the effects of medicinal extract for tonifying kidney to relieve asthma on glucocorticoid receptor (GR) expression in rats with asthma, and to explore its mechanism in treating asthma. Methods: Sixty SD rats were randomly divided into normal control group, untreated group, dexamethasone group, and medicinal extract-prevented, medicinal extract-treated, and medicinal extract-prevented and -treated groups, with ten rats in each group. Asthma was induced by intraperitoneal injection of ovalbumin (OVA) and forced inhalation of atomized OVA. Expression of GR in lung tissues was detected by immunohistochemical method. Pathological changes of the lung tissues were observed by HE straining. Results: Expression of GR was lower in the untreated group than in the normal control group (P<0.05). Expressions of GR in medicinal extract groups were up-regulated as compared with those in the untreated group and dexamethasone group (P<0.05, P<0.01), and there were no significant differences as compared with the normal control group (P>0.05). Conclusion: Medicinal extract for tonifying kidney to relieve asthma can increase the expression of GR in lung tissues of asthmatic rats, which may be one of its mechanisms in preventing and treating asthma.

Objective To investigate the situation and development of international literatures on geriatrics and gerontology in mainland China.Methods The literatures on geriatrics and gerontology written by mainland Chinese scholars as the first author were selected from Thomson Scientific database in 1979-2011 period.Researches on basic theory,summary reports of clinical practice and reviews were collected.The quantity of published articles,article types,international cooperation research and funding programs,hospital rankings,as well as the 2011 geriatrics professional journals,thesis topic disciplines distribution and high-performance papers were analyzed by Thomson Data Analyzer software.Results From 1979 to 2011,the quantity of literatures written by Chinese scholars as the first author (not including Hong Kong,Macao and Taiwan regions) was 1927,including 1769 research articles,86 reviews,18 editorials,54 letters.Average paper was cited 7.6 times and the average number of article citation was 30.6.International cooperation research articles occupied 379 (19.7 %).Articles with research sponsorship were 734 (38.1 %),in which most subject discipline was geriatric and gerontology.Conclusions The development of geriatric medicine in China is rapid.The international scientific and technological cooperation is very extensive.It is important to further improve the world impact of geriatric medicine from China.The development of geriatric medicine in a large,cooperative,comprehensive,interdisciplinary,interagency direction,and the prospective,multicenter,cooperative study need to promote.It is extremely urgent to establish the English version of Chinese journals of geriatrics with a international influence.

Objective To investigate the characteristics of the author groups in 《Chinese Journal of Geriatrics》,in order to provide references for the future construction and development of the author ranks.Methods Bibliometric method was used to analyze the quantity of papers,region distributions,core authors and cooperative rate in 《Chinese Journal of Geriatrics》 from 2009 to 2013.Results The total amount of papers published in 《Chinese Journal of Geriatrics》》 from 2009 to 2013 was 1636,involving 31 provinces,autonomous regions,municipalities and administrative region.Among these,Beijing,Zhejiang,Tianjin and Jiangsu were the 3 top contributing regions,accounting for 54.0 percent (884/1636 papers).The 1636 papers were contributed by 1435 authors (first authors),of whom 1275 authors published only one paper,accounting for 87.7% (1275/1435),and their papers accounted for 77.9% of the total published papers (1275 /1636).27 authors had high yield of 3 or more papers published and deep influence,and they published 95 papers (5.8%).The degree of cooperation was 4.6 (7599 /1636),and the cooperation rate was 93.8% (1534/1636) within the five years.Conclusions 《Chinese Journal of Geriatrics》is quite influential and attractive in the fields of geriatrics,and a good cooperative relationship is displayed between different authors and authors' institutions.

Objective To analyze the articles published in Chinese Journal of Geriatrics from 2008 to 2012 so as to understand the characteristics of published papers and research progress in geriatric medicine.Methods Based on Wanfang database,bibliometric analysis was conducted to analyze the quantity,types,authors,affiliations,fund support of all the articles published from 2008 to 2012 in Chinese Journal of Geriatrics.Results A total of 1567 papers were published in the journal from 2008 to 2012.The column with the most published papers was clinical research (1008 papers,64.3 %),followed by experimental researches,reviews and lectures,investigations etc.The discipline with the most articles published in the journal was cardiovascular medicine,followed by surgery,neurology; respiratory etc.1356 authors from 506 affiliations published paper as the first author in the journal during this five years,with the maximal number being 7 papers and the major affiliation being affiliated hospitals of medical colleges (733 papers,49.3 %).Authors from Beijing,Zhejiang,Jiangsu,Shanghai published more papers than those from other provinces.29.0% (455papers) of the total papers were supported by fund,among which the majority was provincial fund,followed by national fund,municipal fund,ministry fund and military fund.Conclusions A relatively stable core author group has formed for Chinese Journal of Geriatrics,and the articles are of high quality.Chinese Journal of Geriatrics is one of the highest academic journals in geriatric medicine.

Objective To summarize the operative experience of transumbilical single-port laparoscopic cholecystectomy. Method The clinical data of 15 patients underwent transumbilical singleport laparoscopic cholecystectomy between May to October in 2010 was reviewed. Results The operative time was 30-85(45±16) min,hospitalization time was (2.5 ± 1.1 ) d. No surgical complications such as bile leak or uncontrolled hemorrhage occurred postoperatively. All the incision were healed well and the surgical scar was virtually concealed whithin the umbilicus. Conclusions Transumbilical single-port laparoscopic cholecystectomy is feasible and safe when patients are well selected. Comparing with conventional laparoscopic cholecystectomy, it's more manipulatively difficult.

Sleep quality is closely related to human health. It is very important to correctly discriminate the sleep stages for evaluating sleep quality, diagnosing and analyzing the sleep-related disorders. Polysomnography (PSG) signals are commonly used to record and analyze sleep stages. Effective feature extraction and representation is one of the most important steps to improve the performance of sleep stage classification. In this work, a collaborative representation (CR) algorithm was adopted to re-represent the original extracted features from electroencephalogram sig- nal, and then the kernel entropy component analysis (KECA) algorithm was further used to reduce the feature dimension of CR-feature. To evaluate the performance of CR-KECA, we compared the original feature, CR feature and readied CR feature (CR-PCA) after principal component analysis (PCA). The experimental results of sleep stage classification indicated that the CR-KECA method achieved the best performance compared with the original feature, CR feature, and CR-PCA feature with the classification accuracy of 68.74 +/- 0.46%, sensitivity of 68.76 +/- 0.43% and specificity of 92.19 +/- 0.11%. Moreover, CR algorithm had low computational complexity, and the feature dimension after KECA was much smaller, which made CR-KECA algorithm suitable for the analysis of large-scale sleep data.
