Thrombosis is the formation of a blood clot inside a blood vessel and there are two kinds of thrombosis: venous thrombosis and arterial thrombosis. It is a fatal cardiovascular disease and has caused a lot of pain to human body. Through this passage, we analyze the potential mechanism of thrombosis from non-biomechanics and biomechanics respects. Furthermore, the article concludes its current diagnosis and treatment and points out their responding advantages and disadvantages, after which I propose a possible solution for both diagnosing and curing thrombosis with photoacoustic imaging technology which would be convenient and highly efficient to diagnose and cure thrombosis.

Megakaryoblastic leukemia 1 (MKL1) was closely related to the pathogenesis of various human malignant cancers, It has been reported in the literature that MKL-1 could promote the proliferation of gastric cancer cells and affect the cell cycle. And could affect the value-added and migration ability of lung cancer cells.However, The mechanism of MKL-1 affecting autophagy and apoptosis of tumor cells was not clear. Caspase activity and apoptosis inhibitor 1 (CAAP1) was reported to be involved in cell apoptosis, It can participate in the regulation of apoptosis in tumor cells. In this study, human CAAP1 promoter luciferase reporter construct was successfully constructed. Then transfected overexpression vectors of human MKL-1 into 293T cells,and detected the activation of the CAAP1 promoter by luciferase reporter assay. The result showed that transfected the overexpression MKL-1 vectors can enhance the transcriptional activity of CAAP1. Our research will further reveal the apoptosis of gastric cancer cells and may provide theoretical foundations for methods to cure gastric cancer.

Autism spectrum disorder (ASD) is associated with functional coordination disturbances among brain regions. Genetic studies implicated that dysfunctional gamma-aminobutyric acid (GABA) system may play an important role in autism etiology. Based on previous reported static functional connectivity abnormalities of the posterior superior temporal sulcus (pSTS) in ASD, the current study aimed to explore the dynamic functional connectivity (dFC) variability of the pSTS in ASD and its associations with GABA receptor genes expression. Resting-state functional magnetic resonance imaging data obtained from the Autism Brain Imaging Data Exchange repository were analyzed in 209 males with ASD and 298 demographically-matched control males. For each subject, dFC maps of the bilateral pSTS were constructed through Flexible Least Squares strategy, and the variance of the dFC time series at each voxel was further calculated to quantify the temporal variability. Finally, gene expression decoding analysis was performed using NeuroVault to associate the dFC variability abnormalities with expression data of the GABA receptor genes. Compared with typical controls, individuals with ASD showed increased dFC variability between the left pSTS and right temporal regions, including the middle temporal gyrus and fusiform gyrus. In addition, decreased dFC variability was found between the right pSTS and bilateral posterior cingulate cortex in ASD. Gene expression decoding result showed that aberrant dFC variability patterns of the bilateral pSTS were related to GABA receptor genes expression. These findings suggest abnormal dFC variability of the pSTS in ASD and implicate the potential links between these connectivity abnormalities and GABA genes expression.

Maintaining good mental health such as the prevention of severe depressive symptoms is critical for physical health and well-being in older adulthood. However, depression in elderlies is not known quite well and thus cannot be treated adequately. In this study, a large and wide variety of influencing factors from multiple domain areas were investigated using a large nationally representative sample of older people from the English Longitudinal Study of Ageing (ELSA). Five different machine learning algorithms were employed to build the models for the prediction of depression in older age. Several model ensemble strategies were proposed to merge the results from individual predictive models in order to further improve prediction performance. Significant risk or protective factors associated with depressive symptoms in the elder were separately identified in each domain area. The findings from this study will enhance our understanding about the underlying pathophysiology of depression, thus helping develop appropriate intervention strategies to prevent or reduce the onset of depression in older age.

Although collaborative learning has received increasing attention, few studies have examined the differences between online and face-to-face (f2f) collaboration. This study utilized a two-factor experimental design to investigate the influences of collaboration mode (f2f versus online) and learning style on students' cognitive load and engagement. To assess the differences between online and f2f collaboration, cognitive load scale and engagement were collected from two different classes taking the same course at a university in Taiwan. The results show that online collaboration led to a higher cognitive load than that required for f2f collaboration because students have to learn how to use the online collaboration platform. However, online collaboration had higher engagement compared to that for f2f collaboration which represented student were more willing to engage in collaborative technologies. Students who preferred visual learning reported that the use of online collaboration led to less cognitive load and higher sustained attention than that experienced with verbal learning. No significant differences were found related to students' learning style in the f2f collaboration group.

Cardiovascular diseases, mainly atherosclerosis and coronary heart disease, are crucial causes for worldwide morbidity and mortality. Unhealthy lifestyle and diet with high low-density lipoprotein (LDL)-cholesterol level are the major risk factors. Preventions of CVDs need to be taken early in age by changing to more phytosterol-enriched diet. Phytosterol is plant-derived compound with similar structure and function as cholesterol, but when supplied with food, it can lower the serum cholesterol concentration. Studies recommend the daily intake of 2g to 2.5g supplement of phytosterol can significantly reduce plasma LDL-cholesterol level. There are many researches on the mechanisms of cholesterol-lowering effect of plant sterol and plant stanol. It has been found that the differences in solubility and hydrophobicity enable phytosterol to intervene cholesterol from incorporating into micelles and to co-precipitate with cholesterol into solid crystals in intestinal lumen and reduce the absorption of cholesterol. Phytosterol also promotes the transporter gene expression to increase the cholesterol excretion back into small intestine. Furthermore, phytosterol also affects cholesterol metabolism and its transport in blood stream. Therefore, food enriched with phytosterol can be an efficient and safe method of preventing CVDs.

To provide guidance for the study of risk factors of cardiovascular disease in China, we analyze and compared the research hotspots and frontiers of cardiovascular risk factors in China and outside China in this paper. The CiteSpace software is used to visualize the research literature on cardiovascular risk factors from Cnki(China Knowledge Network Internet) and Web of Science core collection database from 2010-2018, and to draw the knowledge map of high-frequency words, research institutions and countries. In this project, a total of 318 Chinese literatures and 9,009 English literatures were screened out as research objects. The number of annual publications assumes an increasing tendency, most of which are concentrated in developed countries or regions. Study of cardiovascular risk factors outside China is significantly taken more seriously than in China. This study shows that the research frontier has already been extended to lifestyle, particulate air pollution, socioeconomic status, depression, stroke and breast cancer, etc. Moreover, children, adolescents and women have been more concerned in the target population. In consideration of the main reasons for cardiovascular disease---Hypertension, diabetes, coronary heart disease, obesity, atherosclerosis and metabolic syndrome, etc., we should pay close attention to the influence on the risk of cardiovascular disease produced by psychological state, living habits, regional differences, air pollution and so on. Meanwhile, we also need to take the screening and prevention of cardiovascular risk more seriously among adolescents.
为了指导中国心血管疾病危险因素的研究，本文对国内外心血管危险因素的研究热点和前沿进行了分析和比较。利用CiteSpace软件对中国知网(Cnki)和Web of Science核心收录数据库2010-2018年关于心血管危险因素的研究文献进行可视化，绘制高频词、研究机构和国家的知识图谱。本项目共筛选出318篇中文文献和9009篇英文文献作为研究对象。年度出版物的数量呈增加趋势，其中大部分集中在发达国家或区域。国外对心血管危险因素的研究明显比国内更重视。这项研究表明，研究前沿已经扩展到生活方式、空气微粒污染、社会经济地位、抑郁症、中风和乳腺癌等。此外，儿童、青少年和妇女在目标人口中更受关注。考虑到心血管疾病的主要原因——高血压、糖尿病、冠心病、肥胖、动脉粥样硬化和代谢综合征等，我们应该密切关注心理状态、生活习惯、地区差异、空气污染等对心血管疾病风险产生的影响。同时，我们也需要更加重视青少年心血管风险的筛查和预防。

For the epilepsy disease, many studies about the thickness of cortex among various brain regions haven been implemented. However, there is few research about the cell distribution of the gray matter of adjacent gyrus and sulcus. Our studies indicate it is possible different that the thickness of the GFAP-IR interlaminar astrocytes somas between in gyri and sulci in epilepsy. Based on this motivation, we proposed a color brain slice image ROI (region of interest) extracting method. A classifying method is imported to compute the comparability between two pixels in the slice image. An improved mechanism of color data query table is designed to accelerate the processing speed. Human brain tissue images acquired during surgical resection for epilepsy are utilized as the experimental object. The regions of most interest can be extracted and the 3D color gradient field can also be visualized. In conclusion, we can not only achieve the information of interlaminar astrocytes, but also provide a technic support for building the information network of epilepsy diseases.

A hierarchical key management scheme for mobile agents in e-medicine system enables users, such as patients, doctors, nurses and health visitors, to conveniently and securely access a remote hierarchical medical database system via public networks. Efficient hierarchical key management schemes do not require heavy computations even if the hierarchical structure has too many levels and participants. Chen et al. recently developed a hierarchical key management scheme with date-constraint for mobile agents. The key management scheme of Chen et al. is based the Elliptic Curve Cryptosystem and allows each secret key to be partnered with a validity period by using one-way hash chains. However, the scheme of Chen et al. fails to execute correctly, violates authenticated key security, and requires hundreds of hash functional operations. This investigation discusses these limitations, and proposes an efficient date-constraint hierarchical key management scheme for mobile agents in e-medicine system, which provides a fast key validation and expiration check phase to rapidly check whether the secret keys are valid and time-expired or not. The proposed key management scheme not only provides more security properties and rapidly checks the validation of secret keys, but also reduces the computational cost..
