Influence of HbA1c on short-term blood pressure variability in type 2 diabetic patients with diabetic nephropathy

The aim of this study was to understand the characteristics of blood pressure(BP)variability in subjects with diabetic nephropathy(DN),and identify the probable predictors affecting BP variability.Fifty-one chronic kidney disease(CKD)-hypertensive patients without diabetes(NDN group)and sixty type 2 diabetic patients with overt DN(DN group)were enrolled in this study.The values of short-term BP variability were obtained from 24 h ambulatory BP monitoring(ABPM).Variance analysis or nonparametric analysis revealed that 24-h systolic BP variability and nighttime systolic BP variability of the DN group were significantly higher than those of the NDN group[(12.23±3.66)vs.(10.74±3.83)mmHg,P<0.05;(11.23±4.82)vs.(9.48±3.69)mmHg,P<0.05].Then the patients of the DN group were divided into two groups according to glycated hemoglobin(HbA1c)level:Group A(HbA1c<7%)and Group B(HbA1c≥7%),and the t-test showed that patients in Group B had larger 24-h diastolic,daytime diastolic,and nighttime systolic/diastolic BP variability compared with Group A.In the DN group,partial correlation analysis revealed that HbA1c exhibited a strong association with 24-h diastolic,daytime diastolic,nighttime systolic and diastolic BP variability(P<0.001,P<0.001,P<0.05,and P<0.001,respectively).Taken together,larger short-term BP variability was detected in hypertensive type 2 diabetic patients with overt nephropathy and renal insufficiency.It may imply that the optimal BP variability level could benefit from a better glycaemic control.     

Improvement of enamel bond strengths for conventional and resin-modified glass ionomers: acid-etching vs. conditioning

Objective:This study deals with the effect of phosphoric acid etching and conditioning on enamel micro-tensile bond strengths(μTBSs)of conventional and resin-modified glass ionomer cements(GICs/RMGICs).Methods:Forty-eight bovine incisors were prepared into rectangular blocks.Highly-polished labial enamel surfaces were either acid-etched,conditioned with liquids of cements,or not further treated(control).Subsequently,two matching pre-treated enamel surfaces were cemented together with one of four cements[two GICs:Fuji I(GC),Ketac Cem Easymix(3M ESPE);two RMGICs:Fuji Plus(GC),RelyX Luting(3M ESPE)]in preparation forμTBS tests.Pre-treated enamel surfaces and cement-enamel interfaces were analyzed by scanning electron microscopy(SEM).Results:Phosphoric acid etching significantly increased the enamelμTBS of GICs/RMGICs.Conditioning with the liquids of the cements produced significantly weaker or equivalent enamelμTBS compared to the control.Regardless of etching,RMGICs yielded stronger enamelμTBS than GICs.A visible hybrid layer was found at certain enamelcement interfaces of the etched enamels.Conclusions:Phosphoric acid etching significantly increased the enamelμTBSs of GICs/RMGICs.Phosphoric acid etching should be recommended to etch the enamel margins before the cementation of the prostheses such as inlays and onlays,using GICs/RMGICs to improve the bond strengths.RMGICs provided stronger enamel bond strength than GICs and conditioning did not increase enamel bond strength.

中国古代图书馆学思想的研究方式：困境与突破

在关于中国古代图书馆学思想的研究中,史学范式强调"中国"和"古代",不能在时间和空间两个维度上焕发活力;学科范式先验地设定了西方的学科标准,导致"以今论古"、"据外律中"地肢解古代思想的本质。研究中国古代图书馆学思想,需要从问题意识出发最终走向体系建构,从而确证中国古代图书馆学并不只是局限于"中国"、"古代"内部自说自话的特殊经验和区域智慧,而是具有走向现代化和世界化的能量。

Economic and Cultural Influences on the Theatrical Consumption of Foreign Films in Singapore

This study investigates audience acceptance of foreign movies in an import-dominated exhibition market—Singapore. The characteristics of home cinema markets and the cultural distances of the film-exporting countries are operationalized in an empirical model to explain the highly varied demand in this import market for international films from various sources. We show that during 2002–2004 release frequencies and box-office performance for films originating in different countries are significantly accounted for by both economic and cultural factors. Films from countries with larger domestic markets and from countries culturally more similar to Singapore experience greater box-office success. Furthermore, an individual foreign film's Singapore box-office performance is explained by its box-office success in its home market and the intercountry cultural distance.     

Assessing the Economic Value of Public Service Broadcasting in Taiwan Using the Contingent Valuation Approach

The objective of the study is to provide empirical evidence on the value of public service broadcasting (PSB) in Taiwan, which is a critical factor when considering the provision of more public funding. Being based on a nationwide telephone survey in Taiwan, this study uses the contingent valuation method to elicit citizens' willingness to pay (WTP) for maintaining the current PSB in Taiwan. The results show that household average WTP per year for PSB is estimated to be NT$982 (US$29.89), which is equal to 0.18% of GDP per capita in 2007. Such WTP estimate is much higher than the current government subsidy for PSB per household, which implies respondents' high appreciation on PSB as well as the potential benefit that Taiwan PSB could bring to the family. Our estimates of WTP provide important information for government authorities and policy-makers when making funding decisions. Furthermore, our survey results also point to some prioritized functions as potential niches on which the Taiwan PSB could focus in the future.
