Antiphospholipid syndrome(APS) is a autoimmune system disorder caused by thrombosis and is usually accompanied with persistent positive. Antiphospholipid antibodies profiles(aPLs) is the key to diagnosing APS. The most frequently detectable aPLs in current clinical applications are anticardiolipin antibodies (aCL), anti-β2 glycoprotein Ⅰantibodies (anti-β2 GPI), and lupus anticoagulant (LA).However, it is found that the current laboratory diagnostic standard for APS based on these three aPL have many defects. The standard can′t meet the clinical needs. In this article, the research and development of antiphospholipid antibody in recent years are summarized, and the clinical value of non-classified standard antibodies such as IgA antibody isotype and anti-domain 1 β2-glycoprotein I antibody are reviewed.

Objective To evaluate medical students′ achievements of studying through the practical base website for humanistic quality education. Methods Totally 61 students from school of nursing and 135 students from the first clinical medical college of Southern Medical University in Guangzhou were organized as volunteers. They were divided into the intervention group and the control group (98 people per group) in completely random method by the Random Number Generators of SPSS 20.0. With a two-month experiment, the humanistic knowledge scores and humanistic caring ability scores of these two groups were investigated by the Humanistic Knowledge Test Paper and the Caring Ability Inventory. And the learning effects of the website by the intervention group was evaluated with the self-designed questionnaire. Results There was no significant difference (P>0.05) between students in the intervention group and the control group when it came to general information. Before the experiment, the score of humanistic knowledge test paper, the total score of caring ability inventory, the score in the dimension of cognition, patience, and courage of the intervention group were 6.29 ± 0.58, 172.40 ± 10.00, 58.98 ± 4.22, 51.56 ± 5.22, 61.86 ± 6.40, the scores of the control group were 6.36 ± 0.63, 172.65 ± 13.49, 59.31 ± 4.05, 50.83 ± 6.56, 62.52 ± 7.28, there were no significant differences between the two groups (all P>0.05). After the experiment, the score of humanistic knowledge test paper, the total score of caring ability inventory, the score in the dimension of cognition and courage of the intervention group were 7.82± 0.62, 182.34 ± 12.78, 65.04 ± 9.12, 65.17 ± 6.58, the scores of the control group were 6.37 ± 0.60, 170.73 ± 8.92, 58.29±5.61, 62.36±6.90, there were significant differences between the two groups (t=2.92-16.67, all P<0.01). The scores in the dimension of patience of the intervention group and the control group were 52.12±3.60 and 51.02±4.34, and there was no significant difference (t=1.94,P>0.05). As shown by the evaluation made by students in the intervention group about the learning effect of the website, the average score was the highest in the field of skills (3.95 ± 0.58), followed by the cognitive field (3.92 ± 0.46) and emotional field (3.75 ± 0.66). Most of the respondents believed that web-based learning could deepen students′ understanding of humanistic quality education (4.13 ± 0.57), independent web-based learning could strengthen the application of online resources (4.06±0.59) and students could master communicative skills required in different situations through web-based learning (4.05 ± 0.58). Conclusions Students are satisfied with the practical base website for humanistic quality education, the website has rich learning contents and can improve students′ interests and motivation. Through web-based learning, humanistic knowledge and humanistic caring ability of students can be improved to some extent. But the website is still in development, it needs an evaluation indicators system in order to do further research for all application effects of the website.

Objectives To develop a measurement for obesity assessment which could be used as a simple tool of risk screening. Methods The data of National Nutrition and Health Survey ( 2002 ) were used to analyze the relationship between body mass index ( BMI ), waist circumference (WC) and chronic diseases, based on which chronic disease index ( CRI ) was established. Receiver operating characteristic curve (ROC) was used to determine the cut-off of CRI and to compare the predictive effectiveness of CRI,BMI and WC on chronic diseases. The kappa test was chosen to estimate the consistency of different cut-off of CRI with BMI and WC. The odds ratios of chronic diseases in different cut-offs of CRI were calculated by multiple Logistic regression analysis. Results CRI was calculated as CRI = BMI + 3.5 WC. In ROC curve,the cut-off of CRI was 300. The predictive effectiveness of CRI was higher than that of BMI and WC. CRI at 300 showed the best consistency with 24 kg/m2 BMI and 85 cm WC (P <0. 05 ). In comparison with CRI <300,the risk of chronic diseases was significantly increased with an increase of 20 U CRI. Conclusion CRI shows good predietive effectiveness and could be used to identify those with higher risk of chronic diseases.

Objective To evaluate the clinical value of computer-aided detection (CAD) system in the diagnosis of breast cancer on mammograms. Methods The mammograms of 136 pathology-proved breast cancer cases were analyzed by CAD system. The results of CAD were compared with that made by radiologists. Results The sensitivity, specificity, and accuracy of CAD system to microcalcification lesions were 93.2% (41/44), 22.8%(21/92), and 45.6%(62/136), respectively. The sensitivity, specificity, and accuracy of CAD system to mass lesions were 82.9%(107/129), 71.4%(5/7), and 82.4%(112/136), respectively. There was middle level agreement between the detection of CAD system and that of the radiologists (Kappa_(mass)=0.424, P_(mass)=0.000; Kappa_(cal)=0.365, P_(cal)=0.013). Conclusion CAD system has the characteristics of high sensitivity and low specificity. It could be the aid of radiologists in breast cancer detection on mammograms.
