Bibliometric Analysis of Patient Navigation Model Applied in Colorectal Cancer Care Based on Web of Science

Background: The mortality rate of colorectal cancer in China is on the rise, which has exceeded the global average rate, thus making the care of colorectal cancer widely concerned. As a comprehensive nursing model, the patient navigation model has shown its effectiveness in improving the quality of life among patients with chronic diseases and reducing the shortage of current healthcare resources in some area. This study aims to identify the current status and dilemma of the patient navigation model applied in colorectal cancer care in China. Methods: Bibliometric method was used to analyze published articles regarding the application of patient navigation model in colorectal cancer care retrieved from the Web of Science database. Statistics were presented using visualization method processed by the Bibliographic Items Co-occurrence Matrix Builder (BICOMB) software. Results: 124 articles, from 2006 to 2018, covering 14 countries, involving 931 researchers, 356 institutions and 60 publications were obtained;American research papers are the largest components of the aforementioned articles;only one of them is written by Chinese authors. The 3 leading institutions in this domain are University OF Rochester, Ohio State University, Icahn School of Medicine at Mount Sinai, yet the distribution of authors is relatively decentralized. “Cancer” is the main journal that publishes the researches in this domain. Research hotspots are on “cancer prevention and screening”, “health disparities”, “economic evaluation”, “patient navigators”, and “ethnicity”. Conclusion: In China, the research on the patient navigation is still in its infancy. Therefore, the Chinese government should provide more endorsement to this particular area and encourage the cooperation with other countries. China, having a long way to go, should further explore patient navigation on colorectal cancer care and establish a model that matches its cultural backgrounds.

守信之心点亮信用建设之路—基于江苏个人信用度调查的实证分析

民众的信用品质对个人信用建设而言意义非凡,了解社会个人信用度的整体状况,并推进个人信用品质培育,是信用建设的重点。本研究对2100名江苏省居民进行问卷调查并得出结论:1) 女性比男性更讲信用;2) 信用度随着年龄的增长而提高,年长者更讲信用;3) 机关事业单位员工的信用较好,而个体工商户的信用相对落后;4) 无贷款或贷款经历的人比有贷款或贷款经历的人更讲信用;5) 不同受教育程度的民众的信用度之间没有差异。上述发现可以为信用教育提供方向,有的放矢,从而提高民众整体信用度,在全社会范围内形成求信之风。

A Power Allocation Scheme Using Updated SLNR Value Based on Perturbation Theory

The performance of downlink multiple-input multiple-output (MIMO) cellular networks is limited by co-channel interference (CCI). In this paper, we propose a linear precoding scheme based on signal-to-leakage-and-noise ratio (SLNR) criteria which can reduce the CCI significantly. Since each user’s SLNR value is corresponding to the largest eigenvalue of the generalized matrix which indicates the channel quality that we propose a scheme to do a dynamic power allocation as an auxiliary way to improve SLNR precoding scheme. We use the perturbation theory to update each user’s SLNR value each time step in time-varying channels rather than directly decompose the channel matrix so as to reduce the amount of calculation. The simulation results show that the proposed scheme offers about 0.3 bps/Hz additional capacity gain and 0.5 dB BER gain over conventional SLNR precoding method with lower computational complexity. And it also obtains about 0.5 bps/Hz additional capacity gain and 1 dB BER gain compared to the scheme only update the preceding vectors.

In-situ template etching synthesis of BiON/BiOCl_(0.9)I_(0.1) heterojunction for photocatalytic degradation of tetracycline

Hierarchical heterostructures have emerged as promising candidates for the efficient photocatalytic degradation of antibiotics owing to their matched energy levels and tunable absorption bands.Herein,we report the facile synthesis of a heterojunction photocatalyst composed of basic bismuth nitrate(BiON)and BiOCl_(0.9)I_(0.1) using a simple room-temperature hydrolysis method.Our results demonstrate that the BiON/BiOCl_(0.9)I_(0.1) composite exhibits superior photodegradation performance compared to pure-phase materials owing to the catalytic enhancement at the heterointerface and the effective separation of the photogenerated carriers.Moreover,the unique three-dimensional microsphere morphology of the synthesized composite enhances its specific surface area and light absorption,further enhancing its photocatalytic activity.In the tetracycline(TC)photodegradation reaction as a model reaction,the catalyst could degrade 88%of TC in just 25 min.Overall,this work provides a promising strategy for the facile and low-cost synthesis of heterogeneous photocatalytic degradation materials.
