METHODS: An electronic search of the MEDLINE, EMBASE and Chinese National Knowledge Infrastructure, which contain articles published from 1966 onwards, was conducted to select studies for this meta-analysis. RESULTS: Fifteen studies with a total of 1547 gastric cancer cases and 450 controls were included in this meta-analysis. Overall, the expression of Notch1, Notch2, Delta-like 4 and Hes1 was significantly higher in tumor tissues of GC compared to normal tissues. Specifically, stratified analyses showed that significantly increased expression of Notch1 was associated with non-cardia location, > 5 cm size, diffuse type, positive lymphovascular invasion and distal metastasis. Statistically significant higher expression of Notch3 was found in diffuse type GC. Jagged1 was also significantly over-expressed in diffuse type and poor differentiation type of GC. DLL4 was significantly over-expressed in advanced T stage, N stage and TNM stage in GC patients. However, the stratified analysis showed that there was no statistically significant difference in Hes1 expression between different subgroups. Sporadic reports showed that Notch1 and Jagged1 were independent poor prognostic predictors in GC. CONCLUSION: The Notch signaling pathway plays an important role in tumor progression of gastric cancer. (C) 2014 Baishideng Publishing Group Inc. All rights reserved.展开更多
目的探讨人乳头状瘤病毒(HPV)与鼻腔鼻窦内翻性乳头状瘤(SNIP)发生、复发及恶变的关系。方法检索Pubmed、Web of science、Embase、Cochrane Library、CNKI、维普、中国知网及万方等数据库,查找2000~2017年国内外公开发表的HPV与SNIP发...目的探讨人乳头状瘤病毒(HPV)与鼻腔鼻窦内翻性乳头状瘤(SNIP)发生、复发及恶变的关系。方法检索Pubmed、Web of science、Embase、Cochrane Library、CNKI、维普、中国知网及万方等数据库,查找2000~2017年国内外公开发表的HPV与SNIP发生、复发及恶变相关的所有病例对照研究文献,应用RevMan 5.3统计软件对各研究原始数据进行统计分析。结果 Meta分析示SNIP组HPV感染率明显高于对照组(P<0.01,OR=19.72,95%CI为7.91~49.18);复发组HPV感染率明显高于对照组(P<0.01,OR=3.10,95%CI为1.90~5.08);恶变组HPV感染率明显高于对照组(P<0.01,OR=2.09,95%CI为1.41~3.09)。结论 HPV感染与SNIP的发生、复发及恶变密切相关。展开更多
