Objective:To understand the reliability and validity of quality of life instruments for cancer patients-brain neoplasm [QLICP-BN (V1.0)], a self-developed quality of life scale for cancer patients.Methods:The quality of life of 112 patients with brain neoplasms in Yunnan Cancer Hospital from March 2012 to November 2013 was measured. The general data questionnaire and QLICP-BN (V1.0) were used for data collection. The reliability, validity and responsiveness of the scale were tested, and then the metric characteristics of the scale were evaluated.Results:The split-half reliability of the total score of the scale was 0.95, the Cronbach αcoefficient was 0.92, and the test-retest correlation coefficient rwas 0.78. After extracting common factors by the principal component method and rotating with the maximum variance, the specific module obtained three principal components, and the cumulative variance contribution rate was 64.18%. The score of specific module was 75.30±17.44 before treatment and 78.91±12.20 after treatment ( t=-2.481, P=0.015). The total score of scale before treatment was 65.26±12.29, and that after treatment was 69.62±10.41, with a statistically significant difference ( t=-4.492, P<0.001). The total responsiveness of the scale was 0.456, showing moderate responsiveness. Conclusion:QLICP-BN (V1.0) has good reliability, validity and a certain degree of responsiveness. It can be used as a measurement tool for the quality of life of patients with brain neoplasms in China.

CT appearances and short-term changes of COVID-19 in subclinical period / 中华放射学杂志

Objective:To explore the characteristics and short-term changes of high resolution CT (HRCT) in subclinical stage of COVID-19.Methods:The HRCT images of 17 COVID-19 patients in subclinical stage were analyzed retrospectively in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology and Wuhan Jinyintan Hospital from January 15 to 31, 2020. There were 4 males and 13 females, age ranged from 25.0 to 51.0 (39.8±7.5) years, who were closely contacted with other COVID-19 patients. The follow-up CT examination was performed within 3 to 6 days after the initial CT examination in all patients. Six patients were treated using anti-virus, anti-inflammation and symptomatic therapy, while the other 11 patients were untreated. The subclinical CT findings and short-term follow-up were analyzed, and the CT changes of short-term follow-up were summarized.Results:The lesions of 17 COVID-19 patients were mainly located at the lower lobes of bilateral lungs (at the left lower lobe in 9 cases and at the right lower lobe in 10 cases in the subclinical stage, at the left lower lobe in 9 cases and at the right lower lobe in 11 cases in the short-term follow-up). The number of involved lung segments increased from 46 in the subclinical stage to 90 in the short-term follow-up. In the subclinical stage, the multiple lesions were found in 13 cases, while in the short-term follow-up, the number of cases with multiple lesions decreased by 7, however the cases with focal lesions increased by 6 and diffuse lesions by 4. The lesions were mainly distributed under the pleura (13 cases) or along the bronchovascular bundle(10 cases). In the short-term follow-up, the lesion in 1 case expanded from the subpleural area to neighbouring bronchovascular bundle. There were 3 main types of the lesions, including ground glass nodule, ground glass opacity and crazy-paving pattern. In the subclinical stage and short-term follow-up, the ground glass opacities were seen in all the 17 cases. In the short-term follow-up, the number of cases with ground glass nodules decreased by 4 and crazy-paving pattern increased by 4. In 6 patients after treatment, the multiple ground glass nodules became single one in 3 cases, and in other 3 cases the multiple ground glass opacities were getting smaller. However, the scope of lesions in 11 patients without treatment enlarged.Conclusion:The HRCT features of the COVID-19 in subcilincal stage have some charicteristics, such as small ground glass nodule, ground glass opacity along the subpleural area or along the bronchovascular bundle, and the great changes can be seen in the short-term follow-up.

Study on visfatin-induced inflammation and necroptosis via LOX-1 in human umbilical vein endothelial cells / 生物医学工程学杂志

The aim of the study is to identify the effects and underlying mechanisms of visfatin on inflammation and necroptosis in vascular endothelial cells. Human umbilical vein endothelial cells (HUVECs) were stimulated with visfatin or pretreated with Polyinosinic acid (LOX-1 inhibitor). By using the Western blot, RT-PCR, immunocytochemistry, enzyme-linked immunosorbent assay (ELISA), MTT and flow cytometry technique, the occurrence of inflammation and necroptosis in HUVECs were evaluated. Our results showed that 100 ng/mL visfatin significantly increased the mRNA and protein expression of monocyte chemotactic protein 1 (MCP-1) and LOX-1 after 24 hours' treatment in HUVECs. However, pretreatment with Polyinosinic acid could significantly reduce the expression of MCP-1 compared with visfatin group. Additionally, 100 ng/mL visfatin could induce the production of necrotic features and increase the mRNA expression of BMF (one of the markers of necroptosis), while pretreating with Polyinosinic acid markedly downregulated the mRNA expression of BMF gene and promoted the cell proliferation. These results indicate that visfatin might induce inflammation and necroptosis via LOX-1 in HUVECs, suggesting that visfatin plays a central role in the development of atherosclerosis.

The effects of PEMF on the activation of human monocytes / 生物医学工程学杂志

The aim of the present study is to investigate the effect of pulsed electromagnetic field (PEMF) on the activation of human monocytes (THP-1). Cultured THP-1 cells were exposed to PEMF stimulation with radiation of 32Hz or 64Hz respectively, using sinusoidal wave, and 1mT, twice a day, 30 minutes each time, with an interval of 8 hours, for 3 days. Those with 0Hz stimulation served as the controls. Monocytes activation was monitored by measuring both the release of monocyte chemoattractant protein-1 (MCP-1) from monocytes and their adhesion to monolayers of human umbilical vein endothelial cells (HUVECs). The adhesion of THP-1 cells to HUVECs was evaluated by cell counting method. The secretion of MCP-1 from THP-1 cells was detected by ELISA and MCP-1 mRNA expression was assessed by real time quantitative RT-PCR. The data showed that exposure to PEMF with above parameters could significantly inhibit the adhesion of THP-1 cells to HUVECs and decrease the MCP-1 mRNA and protein expression. The results demonstrated that exposure to PEMF of 1mT, 32Hz or 64Hz for 3 days could significantly inhibit the activation of THP-1 cells.

Activin A and BMP-4 induce cardiomyocyte-like cells differentiation of human amniotic epithelial cells / 生物医学工程学杂志

Amniotic epithelial cells (AECs) have been expected to be a good cell source for stem cell-based cardiac repair. Activin A signaling is required for cardiac differentiation in human embryonic stem cells (ESCs), and bone morphogenetic protein-4 (BMP-4) is an important regulator that controls stem cell fates. Previous study has established an efficient protocol to generate cardiomyocytes from human ESCs via induction with Activin A and BMP-4. The aim of present study was to test the hypothesis that Activin A and BMP-4 could also induce AECs to differentiate into cardiomyocytes in vitro. Human AECs (hAECs) were isolated from human term placenta by trypsin digestion according to the previous reports. Freshly isolated hAECs were examined to detect the expression of cytokeratin 19 by immunocytochemistry. High-density undifferentiated hAECs at passage 1 were sequential treated with 100 ng/ ml human recombinant Actvin A and 10 ng/ml BMP-4. The expression of cardiac-specific genes was examined before and after in vitro induction of cellular differentiation. Freshly isolated hAEC could express cytokeratin 19, the specific marker of epithelial cells. The data showed that hAECs treated with Activin A and BMP-4 were able to express cardiac-specific genes, including Nkx2.5 and alpha-actinin. Our results demonstrated that Activin A and BMP-4 could induce cardiomyocyte differentiation of hAECs, which might be a novel approach to induce differentiation of AECs into cardiomyocytes-like cells.
