This study was aimed to assess scales with the unidimensional item response models (UIRM) and classical test theory.The reliability and validity of 841 sub-health status samples were analyzed by CTT.Surveying evaluation from the project perspective was also conducted.The results showed that Cronbach'so coefficients in five areas were all larger than 0.6 with relatively high consistency.The scale structures of five areas were relatively good and the CFI was 0.96.When discriminations of all items were larger than 0.3,the sensitivity of item for its area was high.When the scale test information was 33.8,the accuracy of sub-health status was relatively high.However,there were still some items should be further revised.It was concluded that UIRM can be used to evaluate the psychological measurement performance in the project.It is a supplement to the evaluation result of classical test theory.The reliability and validity of sub-health status scale are relatively high.After IRT correction,it can be used for human-computer interaction techniques “preventive treatment” dynamic monitoring.

Objective To evaluate the diagnostic value of contrast-enhanced ultrasound in breast precancerous lesions . Methods Retrospectively analyzed the contrast-enhanced ultrasound model and angiographic predictive model of 465 cases of the A prospective multicenter study of breast nodules contrast-enhanced ultrasound" that led the Sichuan Provincial People′s Hospital from January 2016 to April 2017 ,which included 69 cases of breast precancerous lesions and 396 other types benign lesions ,and the sensitivity ,specificity and accuracy of the diagnosis of breast precancerous lesions were calculated . Results The sensitivity of ultrasound predictive model for the diagnosis of precancerous lesions was 60 .9％ and AUC was 0 .681 . Precancerous lesions mainly showed non-concentricity , increased homogeneity , and increased lesions;other types of benign lesions mainly showed non-centripetal ,high uniformity enhancement and lesion size unchanged . Conclusions Contrast-enhanced ultrasound shows a potential value in the differential diagnosis of precancerous lesions and other types of benign lesions ,that can help clinicians to take early intervention measures for breast precancerous lesions ,but there are still many problems to be solved .

As a kind of intervention measures of traditional Chinese medicine, acupuncture-moxibustion is highly adopted on global clinical practice. Even though the global clinical trial registration system was established more than 10 years ago, the proportion of acupuncture-moxibustion clinical trial registration is still very low; and it is very problematic on the methodological quality and report quality in the published acupuncture-moxibustion clinical trials. In order to manage particularly the acupuncture-moxibustion clinical trials, China Academy of Chinese Medical Sciences, collaborated with China Association of Acupuncture and Moxibustion and World Federation of Acupuncture Societies, established the Acupuncture-Moxibustion Clinical Trail Registry (AMCTR). AMCTR is a secondary registry platform affiliated to the Chinese Clinical Trial Registry (ChiCTR) and WHO International Clinical Trials Registry Platform (ICTRP), specifically for the acceptance and management of clinical trials in the field of acupuncture and moxibustion. It is a nonprofit academic organization, located in China Academy of Chinese Medical Sciences.
