ABSTRACT
BACKGROUND@#AND PURPOSE: Previous studies have explored the association between retinal vascular changes and cognitive impairment. The retinal vasculature shares some characteristics with the cerebral vasculature, and quantitative changes in it could indicate cognitive impairment. Hence, a comprehensive meta-analysis was performed to clarify the potential relationship between retinal vascular geometric changes and cognitive impairment.@*METHODS@#Relevant databases were scrupulously and systematically searched for retinal vascular geometric changes including caliber, tortuosity, and fractal dimension (FD), and for cognitive impairment. The Newcastle-Ottawa Scale was used to evaluate the methodological quality of included studies. RevMan was used to perform the meta-analysis and detect publication bias. Sensitivity analyses were also performed.@*RESULTS@#Five studies that involved 2,343 subjects were finally included in the meta-analysis. The results showed that there was no significant association between central retinal artery equivalents (Z=1.17) or central retinal venular equivalents (Z=1.74) and cognitive impairment (both p>0.05). Similarly, no significant difference was detected in retinal arteriolar tortuosity (Z=0.91) and venular tortuosity (Z=1.31) (both p>0.05). However, the retinal arteriolar FD (mean difference: −0.03, 95% CI: −0.05, −0.01) and venular FD (mean difference: −0.03, 95% CI: −0.05, −0.02) were associated with cognitive impairment.@*CONCLUSIONS@#A smaller retinal microvascular FD might be associated with cognitive impairment. Further large-sample and well-controlled original studies are required to confirm the present findings.
ABSTRACT
Objective The evaluation index system of quality of assisted fertility treatment care was constructed to provide the basis for scientific evaluation of quality of care in reproductive center. Methods Based on the structure-process-outcome (SPO) quality model, evaluation index system for fertility treatment care in the reproductive center was constructed by literature query, field process tracking, Delphi expert consultation and analytic hierarchy process (AHP). Results The effective recovery rate ( RR ) of the two rounds of the questionnaire was 100% . The expert authority coefficient Cr values were 0.813, 0.845 respectively. The W value of the coordination coefficient was 0.331, 0.372, both of which were statistically significant (P<0.01). Finally, an evaluation index system of quality of assisted fertility treatment care with three dimensions, 14 secondary indicators and 47 items was formed. Yaaph software was used to determine the weight coefficients of primary and secondary indicators, and the consistency test ( Cr<0.1) was performed, and the variation coefficients of all tertiary items were <0.20. Conclusions The weight of the quality index system of assisted reproductive treatment care in reproductive center is reasonable, the indicators were clear, systematic and objective, and worthy of clinical promotion.

ABSTRACT
Clinic expert information provides important references for residents in need of hospital care. Usually, such information is hidden in the deep web and cannot be directly indexed by search engines. To extract clinic expert information from the deep web, the first challenge is to make a judgment on forms. This paper proposes a novel method based on a domain model, which is a tree structure constructed by the attributes of search interfaces. With this model, search interfaces can be classified to a domain and filled in with domain keywords. Another challenge is to extract information from the returned web pages indexed by search interfaces. To filter the noise information on a web page, a block importance model is proposed. The experiment results indicated that the domain model yielded a precision 10.83% higher than that of the rule-based method, whereas the block importance model yielded an F₁ measure 10.5% higher than that of the XPath method.
