On the basis of discussing the basic features of rural power grid planning project and the status quo, this paper has constructed evaluation index system of the rural power grid planning project, and based on the characteristics of its particularity and indicators, established a fuzzy comprehensive evaluation model based on set pair analysis. It has carried on the comprehensive evaluation to some county in power grid planning project to verify the validity of the selected method. It will provide referential basis for the scientific decision of county power enterprises.

To express the ambiguity and uncertainty of customer needs importance, an algorithm was proposed. It integrated KJ method, rough analytic Hierarchy Process and KANO model. It calculated the customer needs importance in rough set. A case study of cigarettes customer needs importance illustrated the feasibility and validity of the algorithm.

Kawasaki disease (KD) is associated with the development of coronary arterial lesions (CALs) in children. We aimed to test the hypothesis that circulating 25-hydroxyvitamin D3 [25-(OH)D3] could be identified as a clinical parameter for predicting CALs secondary to KD in children. We enrolled 35 children with KD in the acute phase and measured serum 25-(OH)D3 levels in all of them, then followed up by echocardiography for CALs. Additionally, serum 25-(OH)D3 levels were obtained in 23 febrile children with respiratory tract infections and 30 healthy children. Of the 35 KD children, nine had CALs according to echocardiography and 26 did not (NCALs). Serum 25-(OH)D3 levels were not significantly different between NCALs and healthy children (49.2 ± 23.8 versus 44.1 ± 30.2 ng/ml; P = 0.49). Serum 25-(OH)D3 levels were significantly higher in children with CALs than those without CALs (83.9 ± 26.3 versus 49.2 ± 23.8 ng/ml; P = 0.001). The cutoff value of 65 ng/ml to predict subsequent CALs had a specificity of 0.73, sensitivity of 0.78, and diagnostic accuracy of 0.74. Conclusion: Serum 25-(OH)D3 levels were elevated dur-ing the acute phase in KD children who had subsequent CALs. Serum 25-(OH)D3 levels in the acute phase of KD may be used to predict subsequent CALs.
