ABSTRACT
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.

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
Objective To establish the index system of nursing quality evaluation for patients with hematopoietic stem cell transplantation. Methods Based on the Donabedian structure-process-result three-dimensional quality management model, the evaluation index system of nursing quality of stem cell transplantation was constructed by combining qualitative and quantitative research of literature inquiry, case review, expert inquiry and analytic hierarchy process. Results Through the second round of expert consultation, the effective recovery rate of the expert questionnaire was 100% , the expert authority coefficient was 0.813, 0.859, and the coordination coefficient was 0.235 and 0.278 respectively (P< 01). Three primary indicators, 14 secondary indicators and 48 tertiary indicators were formed to evaluate the quality of care in stem cell transplantation. The index weight coefficient was established and the consistency test was passed. Conclusion The quality index system of hematopoietic stem cell transplantation nursing is well defined, its weight allocation is reasonable, the index is clear, and it is scientific and operational.

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.

ABSTRACT
@#Objective To investigate the effect of long-term cardiac rehabilitation on risk factors with doctor supervision after percutaneous coronary intervention(PCI). Methods One hundred and twelve patients after PCI were divided into the cardiac rehabilitation group(56 cases) and the control group (56 cases). All of the patients were given medication and health education, meanwhile the cardiac rehabilitation group received 4～6 weeks hospitalized cardiac rehabilitation program and one year ambulatory cardiac rehabilitation with doctor supervision. Risk factors were assessed six mouths and twelve mouths after the treatment. Results The risk factors except diastolic blood pressure and body weight index improved more significantly in the cardiac rehabilitation group than in the control group. Clinical event in the cardiac rehabilitation group is lower than in the control group. Conclusion Long-term cardiac rehabilitation with doctor supervision is safe, efficiency and good compliance to improve risk factors of coronary heart disease after PCI except diastolic blood pressure and weight management.
