Objective To identify and verify the different genes expression pattern between human endometrial endothelial cells (HEEC) isolated from endometrial cancer and normal endometrium.Methods Endothelial cells were isolated from 5 patients with endometrial cancer (endometrial cancer group 1) and 5 patients with normal endometria tissue (control group 1) admitted from June to November 2007 in Shandong Cancer Hospital.Global expression patterns of endothelial cells were examined using oligonucleotide microarrays.Tissues from 36 patients with endometrial cancer(endometrial cancer group 2) and 10 normal endometrial tissues (control group 2) admitted from January 2007 to April 2008 were selected to verify the expression of different genes,in which up-regulated genes including ESM1,MMP-10,SPP1 and HMGB1 were tested by quantitative real-time PCR and immunohistochemistry.Results Microarray analyses revealed 317 genes that exhibited ＞ 2-fold or ＜ 0.5 differences were identified (including 191 genes up-regulated and 126 down-regulated).Pathway analysis showed that these genes involved cell cycle,cell adhesion molecules,and extracellular matrix-receptor interaction were obviously predominant.Of them,97 up-regulated genes and 44 down-regulated genes were related to angiogenesis.The mRNA expression of ESM1,MMP-10,SPP1 and HMGB1 in endometrial cancer group 2 were 0.898、3.890、1.433 and 1.881,respectively.Positive expression of SPP1,MMP-10,ESM1 and HMGB1 was observed in endometrial cancer group 2.However,the SPP1,ESM1 and HMGB1 was negative expressed in control group 2.Conclusion It shows that there are the different angiogenesis related genes between endometrial cancer and normal endothelium,which will provide insights into the anti-angiogenesis therapy for endometrial cancers.

ObjectiveTo investigate the current situation of health communication carried out by medical institutions in Shanghai through new media platforms such as WeChat， Weibo， Toutiao， Douyin， Kuaishou， Bilibili and WeChat Videos， and to propose targeted measures. MethodsBased on the systematic collection of new media accounts of medical institutions in Shanghai， and through the combination of keyword screening and manual audit， health communication data of medical institutions on new media platforms were determined. ResultsData from 1 117 new media accounts of 162 medical institutions in Shanghai were collected， including 610 WeChat official accounts， 105 WeChat video accounts， 89 Weibo accounts， 18 Bilibili accounts， 198 Douyin accounts， 37 Toutiao accounts， and 60 Kuaishou accounts， totaling 111 853 posts. After keyword sorting and manual screening， a total of 66 761 health science posts were collected， with WeChat Official Accounts， Douyin， and Weibo having the top three highest number of posts. Video-based new media such as Douyin， WeChat Videos， Kuaishou， and Bilibili had a better communication impact than text and image-based new media like WeChat Official Accounts， Weibo， and Toutiao. Among them， Douyin and Toutiao were the best platforms for video and text-image-based new media， respectively. ConclusionMedical institutions in Shanghai recognize the importance of new media in health communication and have made full use of various media platforms to carry out health communication，having a certain impact on health education. In the future， medical institutions should choose appropriate platforms based on target audiences and content characteristics， fully leverage the advantages of various platforms， explore innovative communication strategies， promote the dissemination of health knowledge， and enhance the health literacy of the public.
