METHODS: A retrospective longitudinal survey of patient demographic and clinical characteristics, disease characteristics, diagnostic methods, management and course of disease was performed. The median follow-up period was 10 years. RESULTS: Of a total of 1100 IBD patients attending the Department of Gastroenterology, 59 (50) [median age 82 years (range 64-101); 25 male (42%)] were identified. These patients were diagnosed with ulcerative colitis (n = 37, 61%), Crohn's disease (n = 14, 24%), and indeterminate colitis (n = 8, 15%). Remission was induced in 40 (68%) patients within a median interval of 6 mo (range 1-21) and immunosuppressive therapy was well tolerated. Histological evaluation based on many biopsy samples and the course of the disease led to other diagnosis, namely SCAD instead of IBD in five (8%) patients. CONCLUSION: OAC is not an infrequent problem for the gastroenterologist, and should be considered in the evaluation of older patients with clinical features suggestive of IBD. Extra awareness and extensive biopsy sampling are required in order to avoid an erroneous diagnosis purely based on histological mimicry of changes seen in SCAD, when diagnosing IBD in the presence of diverticulosis coli.展开更多

Method: Both carotid arteries and arteries of lower extremity were subjected to ultrasonic examination by Doppier's method. Those with much atheromatous plaque formation were ranged into case group, and those with normal result formed control group. Total, free testosterone and estradiol were assayed by radioimmunoassay. C reactive protein (CRP) was assayed by nepheloturbidity. Tumor necrosis factor-α(TNF-α), lnterleukin-6 (IL-6), lnterleukin-8 (IL-8), lnterleukin-10 (IL-10), Interleukin-18 (IL-18), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were assayed by ELISA. The mean difference between two groups and the correlation between free testosterone and cytokines were analysed. Results: Free testosterone was (6.337±3.371) pg/L in case group and (11.375±4.733)pg/L in control group, P〈0.01. No differences were found in total testosterone and estradiol. CRP was (27.294±10.238)mg/L in case group and (12.843±6.318) mg/L in control group, P〈0.01. IL-6 was (41.700±31.385)pg/L in case group and (25.396±20.772)pg/L in control group, P〈0.05. IL-8 was (89.249±58.357)pg/L in case group and (67.873±31.227)pg/L in control group, P〈0.05. sICAM-1 was (470.491±134.078)pg/L in case group and (368.487±97.183)pg/L in control group, P〈0.01. sVCAM-1 was (537.808±213.172)pg/L in case group and (457.275±157.273)pg/L in control group, P〈0.05. There were no differences in TNF-α, IL-10 and IL-18. Correlation analysis showed that FT (free testosterone) had negative correlation with CRP, IL-6 and sICAM-1. Among them FT had well correlation with CRP, correlation index was -0.678. Conclusion: Free testosterone was in negative correlation with atherosclerosis in old-age male. Free testosterone may have the role of anti-atherosclerosis, and this effect was not achieved by its transformation to estradiol. Low tree testosterone level was followed by increased level of inflammatory cytokines. Low free testosterones coexist with inflammation and they both affect the process of atherosclerosis in old-age male.展开更多

Using sur...Old-age pension, a fundamental part of the Chinese social security system, is perceived by the Chinese government as the last support for rural-to-urban migrant workers upon retreating from the labor market. Using survey data collected by the authors, this paper examines a host of factors which influence migrant workers' participation in the old-age scheme. The result shows that individual characteristics, employment status, attitudes toward old-age support and perception of the old-age pension system significantly differentiate two groups of migrant workers between those that have participated in and their counterparts who have not participated in the old-age pension schemes. Among a number of factors, age, educational attainment, holding labor contract, etc. are found to be significant factors influencing migrants' behavior participating(or not participating) the available age-pension schemes. Policy implications for how to improve the rate of participation in existing old-age pension schemes among migrant workers are drawn from the findings.展开更多

Methods: The documental quality of the 389 websites was estimated based upon the following parameters: 1) a combination of quality criteria from the Health Information Locator (LIS—OPS/BIREME) and those from Chile’s Pontifical Catholic University, organized into 17 variables;2) uniformity of reference criteria (Vancouver);3) association between the presence of authorship and a higher number of the quality criteria being fulfilled. We also studied the ranking of the results presented by Google in addition to attributes connected to the websites’ target audience, the types of content, their sponsors and country of origin. Results: Of the 389 websites studied, 111 links were not active (28.53% CI 95% [24.05 - 33.02]) and none of the websites in the sample met all of the 17 quality variables. Authored websites displayed remarkable differences in quality when compared to those which did not identify their authors. Conclusions: Faced with the issue of the proliferation of websites with questionable quality content, and the fact that the ranking of results interferes directly in the internal evaluation of content relevance, we propose that public-health research institutions cooperate with web-searching developers to improve the website-positioning formula, in which the “identified authorship” criterion should play a major role in the ranking system.展开更多

Under the background of continuous promotion of community old-age, the importance of research on the"family" life style of oldage residential facilities has become increasingly prominent. Through field survey of different types of oldage residential facilities and questionnaire interviews, the shortcomings of the old-age residential facilities in Xi’an were compared and summarized, and the key elements of "family" life style of the old-age residential facilities were concluded, which mainly include urban community embeddedness, family structure elements, indoor furnishings and accompanying care system. The "family" life style of the old-age residential facilities can not only maintain the "kinship" living needs, but also conform to the new direction of promoting the "community" of the old-age residential facilities in China.展开更多

Our previous work proposed HumanBoost [1] which improves the accuracy of detecting phishing sites by using users’ Past Trust Decisions (PTDs). Web users are generally required to make trust decisions whenever their personal information is requested by a website. Human-Boostassumed that a database of Web user’s PTD would be transformed into a binary vector, representing phishing or not-phishing, and the binary vector can be used for detecting phishing sites, similar to the existing heuristics. Here, this paper explores the types of the users whose PTDs are useful by running a subject experiment, where 309 participants- browsed 40 websites, judged whether the site appeared to be a phishing site, and described the criterion while assessing the credibility of the site. Based on the result of the experiment, this paper classifies the participants into eight groups by clustering approach and evaluates the detection accuracy for each group. It then clarifies the types of the users who can make suitable trust decisions for HumanBoost.展开更多

Conclusions: Faced with the issue of the proliferation of websites with questionable quality content, and the fact that the ranking of results interferes directly in the internal evaluation of content relevance, we propose that public-health research institutions cooperate with web-searching developers to improve the website-positioning formula, in which the “identified authorship” criterion should play a major role in the ranking system.

文摘The problem of old-age care in China is more and more serious. Under the background of continuous promotion of community old-age, the importance of research on the"family" life style of oldage residential facilities has become increasingly prominent. Through field survey of different types of oldage residential facilities and questionnaire interviews, the shortcomings of the old-age residential facilities in Xi’an were compared and summarized, and the key elements of "family" life style of the old-age residential facilities were concluded, which mainly include urban community embeddedness, family structure elements, indoor furnishings and accompanying care system. The "family" life style of the old-age residential facilities can not only maintain the "kinship" living needs, but also conform to the new direction of promoting the "community" of the old-age residential facilities in China.

文摘Faced with the supply-side reform of the tourism industry, the industrialization of Yunnan oldage tourism will be an inevitable attempt to subdivide the tourism market in Yunnan. Based on the concept of old-age tourism, this study put forward the regional structure of Yunnan’s old-age tourism industry, and pointed out the development direction for the "one center and six districts" of Yunnan old-age tourism. Then from the perspective of system theory, the concept of the old-age tourism complex in Yunnan Province was proposed. At the same time, from the perspective of operation management system, oldage tourism accommodation system, old-age tourism passenger transport system, ethnic cultural products, ecological health products, arts and crafts, health services and rural old-age tourism, the construction idea of the old-age tourism complex in Yunnan Province was proposed.
文摘The characteristics of human figures, variable laws and the basic sizes of each part of human body have been found by means of anthropomctric measurements of the middle-arid old-aged men and data analyses. Also, proposals of how to classify dimensions and sizes of the medium human figures among the middle-and old-aged men have been put forward.
文摘This paper analyzes users’ trust decision patterns for detecting phishing sites. Our previous work proposed HumanBoost [1] which improves the accuracy of detecting phishing sites by using users’ Past Trust Decisions (PTDs). Web users are generally required to make trust decisions whenever their personal information is requested by a website. Human-Boostassumed that a database of Web user’s PTD would be transformed into a binary vector, representing phishing or not-phishing, and the binary vector can be used for detecting phishing sites, similar to the existing heuristics. Here, this paper explores the types of the users whose PTDs are useful by running a subject experiment, where 309 participants- browsed 40 websites, judged whether the site appeared to be a phishing site, and described the criterion while assessing the credibility of the site. Based on the result of the experiment, this paper classifies the participants into eight groups by clustering approach and evaluates the detection accuracy for each group. It then clarifies the types of the users who can make suitable trust decisions for HumanBoost.
