基于CiteSpace的结直肠癌患者生命质量研究

目的：通过中英文文献了解结直肠癌患者生命质量研究现状及发展趋势。方法：运用CiteSpace对中国知网（CNKI）、万方数据知识服务平台、中国生物医学文献数据库、Web of Science核心数据集、PubMed、Cochrane Library中收录的关于结直肠癌患者生命质量研究的中英文文献进行可视化分析。结果：检索得到中文文献1 285篇，英文文献871篇，中英文文献发文量均呈上升趋势，相关研究关注的重点主要是结直肠癌患者造口、抑郁、免疫、肠道功能、化疗及化疗药物，但机构之间、学者之间合作程度及研究类型等方面存在一定差异。结论：中文文献相关研究起步晚、发展快，但在研究质量与研究深度等方面与英文文献相比还有一定差距；国内学者之间、机构之间应加强合作，关心患者肠道功能、心理状况，提高患者体力活动水平，开展更多高质量研究。     

Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The anti liver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its "pharmacodynamic group". By searching the research on the anti hepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an anti hepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an anti hepatoma role. Network pharmacological analysis showed that the core targets of the "pharmacodynamic group" for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and "pharmacodynamic group", it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and "pharmacodynamic group" in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and "pharmacodynamic group".     

钙离子通道蛋白TRPV6及其相关疾病的研究进展

瞬时受体电位亚家族V成员6 (Transient Receptor Potential Channel Subfamily V Member 6, TRPV6) 是一种钙离子高度选择性离子通道，在多种组织中均有表达，控制细胞顶端钙离子的进入，在维持钙稳态中发挥重要作用。TRPV6功能异常会影响体内钙稳态，进而引发新生儿骨骼发育异常、甲状旁腺功能亢进、骨与软骨代谢异常、肾结石和高尿钙症、 以及炎症性肠病和慢性胰腺炎等多种疾病。近年来研究也表明，TRPV6的上调与多种肿瘤的侵袭性增加有关，具有作为肿瘤检测的标志物以及治疗靶点的潜力。本综述将聚焦于TRPV6与其在相关疾病中发挥的作用，旨在为TRPV6作为药物靶点实现临床转化提供理论依据。

A basal‐enriched microRNA is required for prostate tumorigenesis in a Pten knockout mouse model

MicroRNAs (miRNAs) play important roles in prostate cancer development. However, it remains unclear how individual miRNAs contribute to the initiation and progression of prostate cancer. Here we show that a basal layer‐enriched miRNA is required for prostate tumorigenesis. We identify miR‐205 as the most highly expressed miRNA and enriched in the basal cells of the prostate. Although miR‐205 is not required for normal prostate development and homeostasis, genetic deletion of miR‐205 in a Pten null tumor model significantly compromises tumor progression and does not promote metastasis. In Pten null basal cells, loss of miR‐205 attenuates pAkt levels and promotes cellular senescence. Furthermore, although overexpression of miR‐205 in prostate cancer cells with luminal phenotypes inhibits cell growth in both human and mouse, miR‐205 has a minimal effect on the growth of a normal human prostate cell line. Taken together, we have provided genetic evidence for a requirement of miR‐205 in the progression of Pten null‐induced prostate cancer.

八段锦治疗神经根型颈椎病的系统评价与Meta分析

[目的] 系统评价八段锦治疗神经根型颈椎病的临床疗效。[方法] 计算机检索中国知网数据库（CNKI）、维普资讯中文科技期刊数据库（VIP）、万方数据库（Wan-fang）、中国生物医学文献数据库（SinoMed）、Web of science、Clinical Trials gov、Pubmed、EMBASE、CENTRAL、Cochrane Library，查找出八段锦治疗神经根型颈椎病的随机对照试验（RCT），检索时限均从建库至2019年7月1日。两名研究者按照纳入与排除标准独立进行文献筛选、资料提取和偏倚风险评估，应用RevMan 5.3软件对最后纳入的研究进行Meta分析。[结果] 最终纳入10个RCT，共843例患者。Meta分析结果显示：八段锦+常规治疗与常规治疗比较，其临床疗效的总有效率差异具有统计学意义[OR=4.19，95% CI（2.42，7.26），P<0.000 01]；八段锦+常规治疗与常规治疗+颈部“米”字操比较，其临床疗效的总有效率差异具有统计学意义[OR=3.41，95% CI（1.56，7.46），P=0.002]；八段锦+常规治疗与常规治疗比较，其疼痛视觉模拟评分法（VAS）评分差异具有统计学意义[MD=-1.90，95% CI（-1.97，-1.83），P<0.000 01]。[结论] 基于现有的研究，该系统评价显示，与常规治疗相比，八段锦+常规治疗在临床疗效总有效率、VAS评分方面有一定的治疗优势。与常规治疗+颈部“米”字操比较，八段锦+常规治疗在临床疗效的总有效率方面有一定的治疗优势。但由于纳入研究的质量不高，仍需要大样本、多中心、随机、双盲试验及试验参照CONSORT标准和STRICTA声明进行RCT研究。
