von Willebrand factor-cleaving protease (vWF-cp) is a newly identified metalloproteinase. The activity of vWF-cp would vary in different physiological or pathological states. To explore activity detectron of von Willebrand factor-cleaving protease and its clinical application, the vWF-cp activity was measured by a sensitive enzyme-linked immunoadsorbent assay to detect the residual collagen binding activity (R-CBA) of von Willebrand factor before and after digestion with vWF-cp. Moreover, its activity deficiency in patients with thrombotic thrombocytopenic purpura (TTP) and solid tumors was also investigated. The results showed that the residual collagen binding assay was sensitive enough to measure the serum or plasma vWF-cp activity in 87 health individuals, 79 patients suffering from TTP and solid tumors. The coefficient of variation within and between the batches was were 3.60% and 8.35%, respectively. The serum and plasma vWF-cp activity in health individuals was (79.47 +/- 10.78)% (n = 53) and (78.79 +/- 9.17)% (n = 30), respectively, whereas the vWF-cp activity in patients with TTP, benign and malignant tumors was significantly decreased (P values were less than 0.001, 0.03 and 0.001, respectively). It is concluded that the vWF-cp activity in plasma or serum of patients with TTP and solid tumors markedly decrease, especially in patients with TTP. Assay of the vWF-cp activity using R-CBA is a simple method.

OBJECTIVETo investigate the clonal expansion of T cell receptor (TCR) Vbeta subfamily T cells from cord blood induced by bcr3-abl2 peptide in vitro.
METHODST cells from 3 units of cord blood were amplified by anti-CD(3) monoclonal antibody (McAb) and IL-2 with or without synthetic b3a2 peptide. T cell specific cytotoxicity was analyzed by lactate dehydrogenase (LDH) assay, TCR Vbeta subfamilies by using reverse transcriptase-polymerase chain reaction (RT-PCR) and genescan technique.
RESULTSbcr3-abl2 peptide specific cytotoxicity T cells were successfully induced from the 3 units of cord blood by synthetic b3a2 peptide. Compared with that in CD(3) McAb induced cells, distribution pattern of TCR Vbeta repertoire was different in T cells induced with b3a2 peptide. Oligoclonal and oligoclonal tendency TCR Vbeta subfamily T cells could be identified in cord blood T cells induced by b3a2 peptide in 1 or 2 weeks, whereas those induced by anti-CD(3) McAb and IL-2 were mostly polyclonal.
CONCLUSIONThe cytotoxicity T cells with anti-CML specificity could be induced by b3a2 peptide. The specific anti-CML cytotoxicity may be derived from the clonal expansion TCR Vbeta subfamily T cells.

OBJECTIVETo assess the value of PET in the identification of cervical nodal metastases of tongue cancer in comparison with CT/MRI and clinical palpation.
METHODSThirty-eight patients with tongue cancer underwent PET and CT/MRI within 2 weeks before surgery. The results of PET, CT/MRI, and clinical palpation were interpreted separately to assess the regional lymph node status, using histopathological analysis as the golden standard. The differences in the sensitivity, specificity and accuracy among the imaging modalities and clinical palpation were analyzed.
RESULTSThe sensitivity of PET for nodal metastasis identification was 11.1% higher than that of CT/MRI (83.3% vs 72.2%, P=0.423) and 16.6% higher than that of clinical palpation (83.3% vs 66.7%, P=0.248). The specificity of PET was 5% higher than that of CT/MRI (80% vs 75%, P=0.703) and 15% higher than that of clinical palpation (80% vs 65%, P=0.288). The accuracy of PET, CT/MRI, and clinical palpation in identifying cervical nodal metastases was 81.6%, 73.7% and 65.8%, respectively.
CONCLUSIONThe sensitivity, specificity and accuracy of PET for detecting cervical nodal metastases are greater than those of CT/MRI and clinical palpation. Although the results failed to show statistically significant differences, we still recommend that PET be used as a supplementary modality for identifying nodal metastases of tongue cancer.

Objective To systematically analyze the framework and core content of physical activity inclusive school health policies. Methods This study conducted systematic content analysis of key messages of WHO key documents related to physical activity and school health services, and constructed policy and research framework. WHO's key policy documents in the field of school health included: Making Every School a Health-Promoting School Implementation Guidelines, WHO Guidelines on School Health Services, and the Global Criteria and Indicators for Making Every School a Health-Promoting School, and the key documents in the field of physical activity mainly include Global Action Plan for Physical Activity Promotion 2018-2030: Strengthening Physical Activity for a Healthy World, and WHO Guidelines on Physical Activity and Sedentary Behavior (Children and adolescents). Results Physical activity, as a health strategy and development strategy, is one of the most important tools for achieving health-promoting schools. In the area of health and education, the key to building health-promoting schools is to focus on child functioning and development, with the goal of promoting healthy inclusion and equity in schools. In the school setting, physical activity for children and adolescents is integrated into the school health service continuum with a focus on health promotion. At the macro level, the state and relevant authorities should establish a strategic structure and strategic planning for the integration of physical activity into the school health service system. At the meso level, educational institutions should develop and improve school health service policies and programs, and improve school health service tools based on the requirements of WHO school health service guidelines. Child health services are achieved through the provision of high-quality physical education programs and after-school physical activities. At the micro level, guided by global standards for building health-promoting schools, physical activity is promoted in the form of lessons and activities for healthy child development. Integrating physical activity into the school health service system can be done in six areas: school health leadership and governance, school infrastructure funding, school health service delivery that supports physical activity, human resources for school health, school health-related medicine and technology, and school health information system. We need to implement health-promoting school policies, strengthen multi-level school leadership and governance, raise the necessary funds to develop human resources adapted to the construction of health-promoting schools and build programs to support physical activity. Conclusion School health service is an important area for promoting children's health and achieving the UN 2030 Sustainable Development Goals, and physical activity is an important strategy of school health services. Policy documents issued by WHO construct the integration of physical activity into the policy framework of the school health service system, of which the core component is to integrate physical activity into the health-promoting school with educational and physical activity approaches. According to the WHO six building blocks of health service system, the integration of physical activity into the school health requires strengthening school health leadership and governance, improving school infrastructure financing, developing school health human resources, developing school-based health-related medical technologies, and establishing a health information system for sharing student health data.
