Bacterial cellulose (BC) is a natural polymer that has bioactivity, biodegradability and biocompatibility. It displays unique physical, chemical and mechanical properties including high crystallinity, high water holding capacity, nanofibre-network structure, high tensile strength and elastic modulus. Due to its unusual material properties, BC has recently become a kind of attractive biomedical material in the international research.Describes BC's properties, study history and its applications as biomedical materials, especially gives emphasis to introduce the applications of BC on scaffold tissue engineering, artificial blood vessels, artificial skin and the treatment of skin wound, as well as the present study status.

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel, located on cell membranes. TRPV3 is extensively expressed in various organs such as skin, brain, dorsal root ganglia, heart and colon. It's reported that TRPV3 involves in many physiological processes including sensation, skin barrier formation, hair growth and vasodilatation, and pathological processes like pruritus, cutaneous inflammatory disease and cancer. TRPV3 can respond to innoxious warm stimulation (≥ 33 ‍℃‍), endogenous substances (e.‍g., farnesylpyrophosphate) and exogenous small molecules (e.g., carvacrol, camphor and 2-APB). Recently, several natural or synthetic small molecules (e.g., osthole, 74a and dyclonine) have been shown to suppress TRPV3 activity, accompanying with therapeutic efficacy in animal models of diseases, which suggests the potential of TRPV3 as drug target. This paper reviews the research progress on the structure, physiological functions, related diseases and modulators of the TRPV3 channel to provide theoretical references for the future study on TRPV3 channel.

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.

The research and quality control of traditional Chinese medicine has meaningful importance, because it has influence not only in the health and treatment of patients, but also in the solid growth and development of phar-maceuticals companies. In some cases, for the complex of TCM, the common QC method on single or multi-target compounds can't really and truly disclose the quality of the Chinese materia medica. Therefore, a lot of researchers do plenty of works to make clear the effectiveness basis, to improve the quality and realize the modernization of TCM. All of these works close together with modern analysis and separation technology. In this article, a novel analy-sis technology-UltraPerformance Convergence Chromatography (UPC2) based its characters and applications should be introduced. It should be a helpful technology for the TCM researchers to facilitate the study and QC works.

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 prevalence of the occupational hazard of organic solvent and noise in printing and Methods record medium production enterprises in Longgang District of Shenzhen City. A total of 56 printing and record medium production enterprises were selected as the study subjects by judgmental sampling method to analyze the worksite Results survey of occupational health and the key occupational hazard factors. There were 256 organic solvent samples ， detected in 56 enterprises which included a total of 148 terms and 1 358 categories of volatile constituents. The top three （ ）， - （ ） （ ） volatile constituents were toluene 35.5% n hexane 25.7% and methanol 23.8% . The top three detected samples of the （ ， ， ， ， - ， ，- ， eight key chemical occupational hazard factors benzene toluene xylene ethylbenzene n hexane 1 2 dichloroethane ） ， - ， trichloroethylene and chloroform were toluene n hexane and ethylbenzene. In the workplace air toluene was the most risk ， factor of occupational hazard factors in enterprise and in sample detection while no trichloromethane was detected. The toluene in workplace air was found to exceed the national standard with the rate of 2.6%. It showed that 27.9% of the work sites were found occupational noise hazard which was over national standard in the 10 key work sites. Only 64.3% and 57.1% enterprises - performed occupational hazard factors detection and occupational health examination. Both none or invalid toxicant proof - facilities accounted for 33.9% of the enterprises. Both none or invalid noise proof facilities accounted for 78.6% of the Conclusion ， - enterprises. The occupational hazards factor of toluene n hexane and noise were serious in printing and record ， medium production enterprises in Longgang District of Shenzhen City and the occupational health management was imperfect. The occupational regulation should be enhanced in this industry.
