ABSTRACT
Objective@#To explore the short-term effects of communicated activities regarding the China Healthy Lifestyle for All workshop held during September 2018.@*Method@#"National action for three reductions and three health activities" and related content ( "salt reduction," "oil reduction," "sugar reduction," "oral health," "healthy bones," and "healthy weight" ) were used as keywords. Starting September 1, thematic publicity topics were launched and implemented throughout the month. The National Action Office issued promotional materials one day in advance through the WeChat Work Group known as the health promotion network in the mainland, which had been developed by members from different provinces, cities, and counties, to disseminate the materials for use both offline and online. Using search engines such as Baidu search and Sogou search, a third-party professional evaluation agency intelligently captured relevant information and texts from various organizations (including provinces, cities, and countries). The information was gathered and sorted according to different channels and forms; thereby, a database was formed for analysis. The content analysis method was used to quantitatively analyze the change trend of the release volume of related reports, and classified statistics were conducted according to different communication channels and forms. Baidu index, WeChat interactive volume, WeChat index, and Weibo hit times were used for evaluation. Researchers analyzed the difference of release volumes in different provinces (municipalities directly under the central government and autonomous regions), as well as in eastern and central regions.@*Results@#The daily communication trend increased significantly after September, with 42 176 reports on related topics, peaking on September 3 (2 703 reports in a single day); effects of the topic establishment and publicity were shown during the entire month. The Badu index showed the same tendency. The keywords "three reductions," "three health," "all-people action," "oil reduction," "sugar reduction," "salt reduction," "oral health," "healthy bones," and "healthy weight" had become high-frequency words. From the perspective of communication channels, there were 17 576, 11 453, and 8 034 reports by WeChat, the news, and Weibo, respectively, accounting for 41.76%, 27.16%, and 19.05% of the total; these report rates were obviously higher than those of other communication channels. WeChat’s interactions reached 4 064 699, and the WeChat index rose to a peak of 858 275 on September 1, which was 194.44 times higher than on August 10 (before the promotional month); additionally, the number of micro-blogging hits reached 130 907 879. Regarding the form of presentation, in descending order, the most frequent type was graphics, followed by star propaganda, radio drama, and health super material. In addition, the gap between the top five provinces ranked by each channel was large. The number of daily releases varied significantly among provinces (municipalities and autonomous regions), with Beijing taking the top spot with 81 articles, while the western provinces of Xinjiang, Ningxia Hui Autonomous Region, Qinghai Province, and Tibet had relatively low daily releases. Even the gap of rank among the top five in WeChat, news, and individual micro-blogs were larger: Beijing, Shandong Province, and Zhejiang Province were the country’s top three regions in WeChat publishing volume. The communication effect in the eastern, central, and western regions was considerably different, with the eastern region clearly responding better than the other two regions, and the western region had insufficient propaganda capacity as a whole.@*Conclusion@#The communication effect of the China Healthy Lifestyle for All month activities in 2018 was quite effective, but the gap in communication effect by provinces was large.
ABSTRACT
Objective To explore association between serum albumin level and cognitive performance in elderly Chinese.Methods All the subjects aged ≥65 years in the 8 longevity areas in Chinese longitudinal health longevity survey (CLHLS) were invited to participate the biomedical in-depth CLHLS study,information about subjects' demographic characteristics,lifestyle,prevalence of diseases and health status was collected through household-interview.The cognitive performance was assessed with Mini Mental State Evaluation (MMSE) scale.Health examination was conducted by medical personnel and fasting venous blood samples were collected to detect the levels of triglycerides,total cholesterol,fasting glucose,creatine and blood albumin.MMSE score was compared and the trend was analyzed with generalized linear model.Association between albumin concentration and cognitive impairment was analyzed by logistic regression model.Results Generalized linear model showed that adjusted MMSE score increased from 23.22 in the lowest quartile group to 25.07 in the highest quartile group (P for linear trend ＜0.001).Logistic regression analysis results showed that the higher albumin level was associated with the lower risk of cognitive impairment (P＜ 0.001),the OR decreased linearly with the increasing level of albumin (P＜0.01),with the OR (95％CI) for the lower,higher and highest quartile groups was 0.64(0.45-0.91),0.60(0.40-0.89) and 0.43 (0.27-0.69),respectively,compared with the lowest quartile group.Conclusion High level of serum albumin was associated with low risk of cognitive impairment.

ABSTRACT
Objective To determine the diagnostic value of cardiovascular magnetic resonance (CMR) in children with myocarditis. Methods A total of 27 children with myocarditis were examined with cardiac MRI, including 16 new?onset cases and 11 chronic cases, as well as 14 cases with non?myocarditis. Sequences included SSFP in axial, two chamber, four chamber and short axis, T2?weighted triple inversion recovery, T1?weighted spin echo before and after gadolinium injection, and inversion recovery?gradient echo after gadolinium injection(late gadolinium enhancement, LGE) in axial and short axis. Qualitative and quantitative image analysis was performed to obtain focal T2 signal intensity and early enhancement signal intensity(SI) ratio of myocardium to skeletal muscleon EGE and LGE.The sensitivity, specificity and accuracy were calculated. Mann?Whitney and χ2 test were used for statistical comparison. Results The median value of EF was 60.20%(44.40%,70.20%), median value of T2W SI ratio was 2.50(2.04, 3.79),and there were 13 cases with LGE positive findings in myocarditis group. The median value of EF was 73.60%(65.40%,75.85%), the median value of T2WI SI ratio was 1.85(1.77, 2.15), and one case presented LGE positive sign in non?myocarditis group. There were significant statistical differences between the two groups (Z=-2.94,-2.52 ,χ2=5.19 ,P<0.05). The sensitivities for T2WI, EGE, LGE were 81.5%(22/27), 14.8%(4/27) and 48.1%(13/27) respectively. The specificities for T2WI, EGE, LGE were 57.1%(8/14), 100.0%(14/14)and 92.9%(13/14) respectively. The diagnostic accuracies for T2WI, EGE, LGE were 73.2%(30/41), 43.9%(18/41) and 63.4%(26/41) respectively. The best diagnostic performance was obtained when“any?two”of the three sequences were positive in the same patient, yielding a 51.9%(14/27)sensitivity, 92.9%(13/14) specificity, and 65.9%(27/41) diagnostic accuracy.Conclusions The combined CMR approach using T2?weighted imaging, early and late gadolinium enhancement, provides a high diagnostic accuracy and is a useful tool in the diagnosis and assessment of children with myocarditis.
