Progress on contact lens for extended ophthalmic drug delivery / 国际眼科杂志(Guoji Yanke Zazhi)

Conventional eye treatment formulation such as eye drops has shortcomings including low drug utilization and poor patient compliance. The contact lens(CL), well-known as visual correction lens, is considered to be a more promising ophthalmic drug delivery vehicle owing to its good biocompatibility, long-term wearing comfort, prolonged drug residence time and improved bioavailability. In order to improve the drug loading efficiency and prolong the release time, researchers have developed a variety of strategies to modify traditional CL, including the introduction of vitamin E molecular barrier, application of molecular imprinting technology of CL, increasing interactions between the drug and polymer matrix by introducing special genes, and incorporation of nanocarriers or drug-loaded polymer films. In this paper, the preparation methods and pros and cons of drug-loaded CL are reviewed. At last, the existing problems and future developments of CL as ophthalmic drug delivery carrier are briefly discussed.

Research Status and Application Prospects of Telomere Length Analysis / 中国生物化学与分子生物学报

Telomere is one of the basic functional elements for maintaining genome stability. Telomeres can become shorter due to cell divisions and environmental factors. Critically shortened telomeres eventually lead to cellular replicative senescence. Telomere length is an important parameter of telomere function, which determines the stability of chromosomes and the ability of cell proliferation. Currently multiple methods have been developed for the analysis of telomere length, including terminal restriction fragment (TRF) analysis, quantitative polymerase chain reaction (qPCR), single telomere length analysis (STE-LA), telomere shortest length assay (TeSLA) and telomere length combing assay (TCA) based on DNA, as well as quantitative fluorescence in situ hybridization (Q-FISH) based on cellular levels. Different analysis methods are applied to obtain different telomere relevant variables. In the review, we discuss the principle and application advantages of each telomere length analysis, which may help researchers select an optimal assessment approach to better address specific research questions about telomere in either model organisms or humans.

Modulation effect of Acanthopanax senticosus polysaccharides through inflammatory cytokines in protecting immunological liver-injured mice / 中国中药杂志

The aim of this paper was to discuss the protective effect and mechanism of Acanthopanax senticosus polysaccharides( ASPs) on immunological liver injury caused by conanavalin A( Con A). BALB/c mice were randomly divided into seven groups: control group,model group( Con A),low-,medium-,and high-dose( 36. 25,72. 5,145 mg·kg~(-1)) ASPs groups,bifendate( 200 mg·kg~(-1),positive drug) group and pyrrolidinedithiocarbamate( PDTC,NF-κB inhibitor,200 mg·kg~(-1)) group. ASPs groups and bifendate group were given with corresponding drugs by ig administration once daily for 7 d. Control group,model group and PDTC group were given with normal saline by ig administration once daily for 7 d. After the last ig administration,PDTC was given in DTC group by iv administration( 200 mg·kg~(-1)); 0. 5 h after that,Con A( 20 mg·kg~(-1)) was injected via the tail vein to induce immunological liver injury in all the mice except normal control group. The mice were killed 8 h later and their liver tissues were collected for histopathological examination. The contents of nitric oxide( NO),superoxide dismutase( SOD),malondialdehyde( MDA),reduced glutathione( GSHPX),interleukin( IL-1β) and tumor necrosis factor( TNF-α) in liver tissues were detected by kit assay. Western blot method was used to detect TNF-α,intercellular cell adhesion molecule-1( ICAM-1),inducible nitric oxide synthase( i NOS) and nuclear factor( NF-κB) protein expression in liver tissues. As compared with model group,ASPs not only could reduce the activity of MDA,NO,IL-1β and TNF-α,but also increase the content of GSH-PX and SOD; at the same time,the protein expression levels of TNF-α,ICAM-1,i NOS and NF-κB were reduced in liver tissues; in addition,inflammatory cell infiltration was alleviated,hepatocyte cytoplasm was loose and swollen,and nuclear condensation and staining were improved. ASPs has a protective effect on immunological liver injury,and the mechanism may be associated with regulating secretion of inflammatory cytokines and the expression of adhesion factor through NF-κB signaling pathway.

Analysis of the financing policy of integrating NCMS and URBMI:Based on the perspective of equity / 中国卫生政策研究

Objectives:This paper intends to analyze the financing policies of integrating NCMS and URBMI in terms of equity. Methods:Data on the financing of NCMS and URBMI from 2008 to 2015 were collected from the China health statistics yearbook (2009—2012) the China health and Family Planning Statistics yearbook(2013—2016),the National Handbook of NCMS Information(2008—2015),the China human resources and social security statistics year-book (2009—2016),and the China social security yearbook(2009—2015)."Ability to pay"approach was introduced to measure the inequity in health financing of medical insurance for urban and rural residents. The proportion of indi-vidual contributions as to NCMS and URBMI as a percentage of the per capita disposable income was used as an actual indicator to analyze the equity in health financing between rural and urban residents. Results:The URBMI had a finan-cing mechanism that was similar to that used by NCMS in that public finance accounted for more than three quarters of the pooling funds,and the individual contribution accounts for less than? of the per capita contribution amount. The scale of financing for NCMS was less than 5% of the per capita net income of rural residents and less than 2% of the per capita disposable income of urban residents for URBMI. Individual contributions to the NCMS and URBMI funds were less than 1% of their disposable and net incomes. The disparities in health financing between urban and rural resi-dents in China was not improved as expected with the introduction of NCMS and URBMI. Conclusions:The proportion of individual contributions to the URBMI and NCMS funds were small in terms of contributors'incomes. The equal financing per capita for URBMI and NCMS masks the inequality of urban and rural residents in the financing of medical insurance.

Objectives:To analyze the effectsof family doctor contracting service on the integration of medical care and prevention and its mechanism. Methods:Based on the representative sampling, 541 family doctors from seven districts were surveyed, and focus group and personal interviews were conducted withfamily doctors and other relevant informants. Descriptive statistical analysis was mainly used to analyze quantitative data and NVIVO 9. 0 was used for encoded qualitative data. Results ; Different contracted service models have different effects on medical protection on medical care and prevention. The contractingservice with the family doctor is helpful to facilitate the integration of medical care and preventive treatment ; the signing service that helps the team members to get effective incentives and personal paid contracts can help promote the combination of medical defense and preventive treatment ; whereby the service content includes basic medical treatment. Moreover, signing a family doctor contract with public health services can also help promote medical integration. Suggestions :Family doctor contracting services should implement team and individual contracted services. Designing a comprehensive service package that integrates basic public health service projects and basic medical and personalized health management services should be prioritized to reflect the concept of covered medical care and preventive treatment. A new approach to explore the path of integration of basic public health and medical insurance fundsshould be found to strengthen the combination of medical and preventive measures, and promote the transformation of general practitioners from service gatekeepers to health gatekeepers.
