The Brodmann area(BA)-based map is one of the most widely used cortical maps for studies of human brain functions and in clinical practice;however,the molecular architecture of BAs remains unknown.The present study provided a global multiregional proteomic map of the human cerebral cortex by analyzing 29 BAs.These 29 BAs were grouped into 6 clusters based on similarities in proteomic patterns:the motor and sensory cluster,vision cluster,auditory and Broca's area cluster,Wernicke's area cluster,cingulate cortex cluster,and heterogeneous function cluster.We identified 474 cluster-specific and 134 BA-specific signature proteins whose functions are closely associated with specialized functions and disease vulnerability of the corresponding clus-ter or BA.The findings of the present study could provide explanations for the functional connec-tions between the anterior cingulate cortex and sensorimotor cortex and for anxiety-related function in the sensorimotor cortex.The brain transcriptome and proteome comparison indicates that they both could reflect the function of cerebral cortex,but show different characteristics.These pro-teomic data are publicly available at the Human Brain Proteome Atlas(www.brain-omics.com).Our results may enhance our understanding of the molecular basis of brain functions and provide an important resource to support human brain research.

Multiple myeloma is a plasma cell disease with the second highest incidence among hematological malignancies. Its risk of concurrent thrombosis is high, which greatly affects the quality of life and even endangers life of multiple myeloma patients. The pathogenesis of thrombosis in patients with multiple myeloma is complex, which is still unclear. However many mechanisms are considered to be related to hypercoagulable state in patients with multiple myeloma. Currently, there is a lack of thrombosis risk assessment model for multiple myeloma. Therefore, this paper reviews the research and the latest progress of venous thrombosis in patients with multiple myeloma, and provides a theoretical basis for the prevention and treatment of thrombosis.

Objective To investigate the clinical diagnostic value of circulating tumor cells (CTCs)and circulating cell-free DNA (cfDNA) in peripheral blood samples in breast cancer. Methods From July 2017 to April 2018, 47 patients with BMC (7 in stage Ⅱ, 19 in stage Ⅲ and 21 in stage Ⅳ), 24 patients with benign breast diseases and 28 healthy people were selected. After collecting peripheral blood samples, serum and blood cells were separated. The size-based high-throughput microfluidic chip was used to capture CTCs. The real-time fluorescent quantitative PCR based on Alu sequence was used to detect the length of cfDNA(247 bp, 115 bp)in the serum, and the ratio of amplified products of long and short fragments was used as the index of DNA integrity. The Mann-Whitney U test or Kruskal-Wallis H test was used to compare the differences between the groups and analyze the relationship between CTCs and cfDNA and clinical parameters of breast cancer. The ROC curve was drawn and the area under the curve (AUC) was used to evaluate the feasibility of blood cell CTCs and plasma cfDNA detection as diagnostic criteria. Results The CTCs and cfDNA of 47 BMC patients were analyzed. The CTCs and cfDNA integrity index (Alu 247/115) of BMC patients were significantly higher than those of physical examination patients[(13.98± 12.36)cells / ml vs (1.14 ± 1.35) cells / ml; 0.7687 ± 0.3868 vs 0.5094 ± 0.2456], and the difference was statistically significant(the U value was 126.5,359.0;P<0.001), the area under ROC curve of CTCs was 0.885 (95%CI: 0.805-0.965), cut-off value was 7.68/ml, sensitivity was 80.4%, specificity was 96.4%. The area under ROC curve of Alu 247/115 was 0.727(95%CI: 0.608-0.847), cut-off value was 0.431, sensitivity was 71.7%, specificity was 71.4%. The AUC of CTCs and Alu 247/115 was 0.919 (95%CI 0.854-0.984), which was higher than the single test of each indicator. Conclusions CTCs and cfDNA may be the potential biological indicators for breast cancer diagnosis. The combined detection of CTCs and cfDNA maybe improve the diagnosis rate of breast cancer patients.

Objective To investigate the current status of psychological capital, career plateau and turnover intention in ICU nurses and to analyze the influence of psychological capital and career on turnover intention. Methods A total of 233 ICU nurses from the 2nd Affiliated Hospital of Wenzhou Medical University who met the criteria were selected by convenient sampling from February to April 2017. The nurses were investigated with the Psychological Capital Questionnaire-Chinese (PCQC), Career Plateau Questionnaire (CPQ) and Turnover Intention Scule (TIS). Totally 233 questionnaires were handed out and 224 valid questionnaires were collected. Results The total score of psychological capital in the 224 ICU nurses was (88.53±13.16), and the highest score was found in the dimension of self-efficacy, while the lowest score was in the dimension of hope; the total average score of career plateau was (3.83±0.92); and the score of turnover intention was (16.82±5.01). According to the hierarchical stepwise regression analysis, contractual employment, hope, hierarchical plateau and content plateau were the main influencing factors of ICU nurses' turnover intention, which could account for 39.8% of the total variation. Conclusions ICU nurses show a strong turnover intention, and contractual employment, hope, hierarchical plateau and content plateau may affect their turnover intention. ICU nursing managers should formulate proper and effective improvement strategies for psychological capital and alleviation strategies for career plateau based on the current status of psychological capital and career plateau in nurses and take proper measures to enhance their enthusiasm and job satisfaction of contractually employed nurses, and reinforce the stability of ICU nursing team.

Objective To investigate the clinical value of the intervertebral disc morphous in patients with thoracolumbar vertebral compression fracture. Methods The MRI, X-ray and CT data of 75 patients with thoracolumbar vertebral compression fracture were retrospectively analyzed. The intervertebral disc damage degree was observed, and its correlation with vertebral fracture degree and endplate damage degree was studied. The vertebral body leading edge height, intervertebral space height and back convex Cobb angle in patients with different intervertebral disc damage degree were measured. Results The intervertebral disc damage degree height was positively correlated with endplate damage degree (P<0.01), and the intervertebral disc damage degree was positively correlated with fracture degree (P<0.01). With the increase of the intervertebral disc damage degree in patients with Ⅰ - Ⅳtype intervertebral disc damage, the vertebral body leading edge height and intervertebral space height gradually became smaller: (0.68 ± 0.05), (0.61 ± 0.03), (0.58 ± 0.03), (0.42 ± 0.05) mm, and (0.31 ± 0.06), (0.29 ± 0.03), (0.24 ± 0.06), (0.22 ± 0.02) mm, and there were statistical differences (P<0.05). There was no statistical difference in back convex Cobb angle in patients with different intervertebral disc damage degree (P>0.05). Conclusions It is more important to observe the morphological changes of the intervertebral disc in patients with thoracolumbar vertebral compression fracture, and the damage degree is closely related with the vertebral fracture degree and endplate damage degree.

Background and purpose:Adenosine triphosphate-binding cassette superfamily G member 2 (ABCG2), which has been found over-expressed in a variety of cancer cells, takes part in the drug resistance of cancer through effux of anticancer drugs. The purpose of this study was to investigate the mechanisms of human glioblastoma cells sensitivity to pyropheophorbide-a methyl ester (MPPa)-mediated photodynamic therapy (PDT) eradicating tumour cells and its relationship to ABCG2.Methods:U87 and A172 glioma cell lines in the logarithmic growth phase were selected and exposed to the treatment of MPPa-PDT and MPPa-PDT+fumitremorgin C (FTC) respectively. The cell viability was measured with the use of CCK-8 assay. The expression of ABCG2 was detected by Western blot. The intracellular contents of MPPa in each group without illumination were tested by lfow cytometry. Flow cytometry with AnnexinⅤ-FITC/PI double staining was used to detect the cell apoptotic rate. DCFH-DA staining was used to assess the generation of intracellular reactive oxygen species (ROS).Results:The MPPa-mediated PDT could eradicate A172 and U87 cancer cells in an energy-dependent manner. The light energy density in A172 was 8 times of that in U87 when the cell viability reached median lethal dose after MPPa-mediated PDT. The high expression of ABCG2 in A172 cells affected the accumulation of intracellular MPPa. Inhibition of ABCG2, not only could enhance the eradicating effect of MPPa-PDT on A172 cells, but also could increase the yield of ROS triggered by MPPa-PDT and the accumulation of intracellular MPPa.Conclusion:The human glioblastoma cell line A172 is insensitive to MPPa-mediated PDT. The mechanism may relate to ABCG2, which decreases the MPPa content in cancer cells through effux of MPPa, resulting in decline of cytotoxicity.
