Developing a competence framework for gerontological nursing in China: a two-phase research design including a needs analysis and verification study.

BACKGROUND: China faces a serious shortage of competent nurses who can address the healthcare needs of older people in an ageing society. Chinese higher education institutes face serious challenges when it comes to developing new curricula that are capable of educating sufficient numbers of competent gerontological nurses. Therefore, the aim of this research study was to identify and verify competencies for gerontological nurses in China that are needed to provide nursing care for the growing number of older people in all care settings. This study takes into account the possible opportunities that trends and developments may offer in the near future. METHODS: In this study, a two-phase research design was used. The first phase concerned needs analysis, including a situational analysis, a trend analysis and a competence analysis. This process resulted in a draft competence framework. The second phase addressed the verification of the competence framework through a two-round Delphi study with a panel of Chinese and European experts. This process led to the final competence framework. RESULTS: The final competence framework for gerontological nursing in China included six competencies divided into 13 essential and five relevant learning outcomes. The competencies are: 'providing gerontological care', 'communication and collaboration', 'organization of gerontological nursing care', 'health promotion', 'evidence-based nursing and lifelong learning' and 'professional behaviour'. CONCLUSION: The framework comprehensively covers the six core competencies that nurses who care for older people should possess. These competencies are well-embedded in a Chinese context. The framework therefore offers concrete, practical suggestions for the competencies and skills that nursing graduates will need to work in current and future professions related to gerontological nursing education and practice.

Biocontrol potential of Burkholderia sp. BV6 against the rice blast fungus Magnaporthe oryzae.

AIM: To investigate the broad-spectrum antifungal activity of Burkholderia sp. BV6, that is isolated from rice roots and its biocontrol potential against rice blast caused by Magnaporthe oryzae. METHODS AND RESULTS: We evaluated the ability to isolate BV6 in the biological control of rice blast disease and investigated its antifungal mechanisms. BV6 strongly inhibited the hyphal growth of M. oryzae Guy11 and other plant pathogenic fungi, and pot experiments showed that BV6 significantly decreases the disease index of rice blast from 47.5 to 24.6. The secreted small-molecule secondary metabolites were regarded as weapons during the antifungal process by inhibiting the germination of M. oryzae conidia and mycelial growth, and thereby prevent the following infection. Liquid chromatography-mass spectrometry analysis of the metabolites from the supernatant of isolate BV6 showed that the antifungal weapons of isolate BV6 are novel, small, molecular hydrophilic compounds that are different from reported antifungal compounds. CONCLUSIONS: The isolate BV6 inhibits the M. oryzae infection by the production of small-molecule antifungal compounds. SIGNIFICANCE AND IMPACT OF THE STUDY: The current study discovers the role of the Burkholderia sp. BV6 in the biocontrol of plant pathogenic fungi. Therefore, isolate BV6 is a potential candidate for developing a microbial formulation for the biocontrol of the most common disease of rice blast.

Clinical advances of tendon tissue engineering materials in tendon injury / 中国组织工程研究

BACKGROUND:The research and development of scaffold materials is the key to tissue engineering, as the scaffold can provide a stable external environment for cell growth.OBJECTIVE:To summarize the clinical advances in tendon tissue engineering materials.METHODS:We searched CBM, CNKI, CSTJ and PubMed database for relevant articles published from January 2004 to May 2016. The keywords were tissue engineering, tendon injuries, biological scaffold, tendon healing in Chinese and English, respectively.RESULTS AND CONCLUSION:The commonly used tissue engineering tendon materials include natural polymer materials, biological derivatives, synthetic materials and composite materials. Natural polymer materials retain the three-dimensional network structure of the normal tissue, with good biocompatibility but poor mechanical properties and degradation speed. Synthetic polymer materials present with good mechanical properties and biodegradability, but have low hydrophilicity and poor cell adhesion capability. Composite materials as an effective combination of the two above-mentioned materials exhibit a certain potential in clinical practice. Biological derivatives come from organisms, and have a net structure and biomechanical properties most similar to the human body after appropriate treatment. Additionaly, these derivatives also have the normal physiological activity and functions, which are considered as the future development direction of biomedical materials.

Qijie theory of LAI's Tongyuan acupuncture technique / 中国针灸

Qijie theory is one of the important components of TCM meridian and collateral system. It is the shortcut for the communication from the exterior to the interior and for the transverse connection, strengthens the therapeutic effects of acupuncture and moxibustion on the disorders of internal organs and enlarges the indications of acupoints. Professor LAI Xinsheng originally creats Tongyuan acupuncture technique. It is a kind of acupuncture therapeutic methods, including promoting the circulation of the governor vessel, regulating the mind and conducting qi to the origin. In order to analyze the connection between Tongyuan acupuncture technique and traditional meridian and collateral theory, the connotations of Tongyuan acupuncture technique and qijie, as well as the in-terrelationship between them are taken as the basis in the paper. By tracing the literature records, the original concept of qijie is detected. Through proving clinically Tongyuan acupuncture technique, it is revealed that qijie is the arrowhead on the main road of meridian qi circulation and is the essential connotation of the direct path of the body surface connecting with the deep layers of the body as well as the zangfu organs and tissues. It is summarized that the traditional qijie theory provides the powerful theoretic evidence for the treatment with Tongyuan acupuncture technique.

Prospect of tissue-engineered tendons in clinical applications：how to improve mechanical properties, tissue integration and late-stage degradation / 中国组织工程研究

BACKGROUND:Tissue-engineered tendons have been used to repair the damaged tendon tissue. Use of tissue-engineered tendons for repair of tendon injury has become a hot spot in this research field. OBJECTIVE: To elaborate the types, advantages and disadvantages of seed cels, the design method, advantages and disadvantages of scaffold materials, and the factors that induced the formation of tendon, so as to promote the optimization of each joint, al of which benefit for mature construction of tissue-engineered tendons. METHODS: The related reviews and paper reports of tendon tissue engineering published from January 2000 to January 2015 were retrieved from Chinese Biomedical Literature Database (CBM), China Knowledge Resources Database (CNKI) series database, Chinese Citation Database and PubMed database. The key words were “tissue engineering; tendon; tendon defect”. The research progress of seed cels, scaffold material and induction factors were analyzed. RESULTS AND COMCLUSION:The recent research of tissue-engineered tendons for repair of tendon injury has been summarized. Seed cels, scaffold, induction factors were discussed. Tendon stem cels, as a kind of seed cels, are currently the first choice in the process of tissue engineering tendon research, because tendon stem cels have the homology of the homogenous or autologous tendons and possess strong differentiation and proliferation capacities. However, there have been no systematic schemes regarding acquisition and proliferation and culture of tendon stem cels. The currently designed tissue-engineered tendons cannot meet the clinical requirements because of poor mechanical properties of tendon tissue, poor integration with the host tissue, being susceptible to degradation in late period and functional disuse. Induction factors are the laft key factors for tissue-engineered tendons for repair of tendon injury. The selection and use of induction factors are prerequisites for the regulation of tendon tissue development. But the categories of induction factors and the association and interrelationship between induction factors have not been fuly clear and studies are needed to further investigate these uncertainties.
