| 1 | 外显子测序识别脑干胶质瘤体细胞获得性功能PPM1D基因突变显示文摘发生于脑干和丘脑的胶质瘤是一类毁灭性肿瘤,难以通过手术切除。为确定这些肿瘤的遗传和表观遗传学背景,作者对14例脑干胶质瘤( BSGs)和12例丘脑胶质瘤病例进行外显子组测序。同时该团队通过针对性突变分析对另外24例该类肿瘤及45例脑胶质瘤进行全基因组甲基化谱进行分析。这项研究发现肿瘤特异性突变PPM1D,该突变编码野生型p53蛋白诱导的蛋白磷酸酶1D(WIP1),其在37.5%的脑干胶质瘤中存在标志性的H3F3A基因突变导致编码第27号染色体使赖氨酸转换为甲硫氨酸。脑干胶质瘤中PPM1D基因突变和TP53基因突变互斥抑制并且在体外实验中可以衰减p53蛋白活化。 PPM1D基因突变能够缩短外显子6来增强PPM1D抑制DNA损伤反应的检验CHK2蛋白激活的能力。这些研究结果表明PPM1D可以作为体细胞突变常用的靶点以及脑干胶质瘤治疗中的潜在靶点。 | Zhang L Chen L H Wan H 王晶晶 许春伟 张博 | 2014 | 临床与实验病理学杂志2014，30，12： | 15 |
| 2 | Mechanosignaling activation of TGFβmaintains intervertebral disc homeostasis显示文摘Intervertebral disc(IVD) degeneration is the leading cause of disability with no disease-modifying treatment.IVD degeneration is associated with instable mechanical loading in the spine, but little is known about how mechanical stress regulates nucleus notochordal(NC) cells to maintain IVD homeostasis. Here we report that mechanical stress can result in excessive integrin α_vβ_6-mediated activation of transforming growth factor beta(TGFβ), decreased NC cell vacuoles, and increased matrix proteoglycan production, and results in degenerative disc disease(DDD). Knockout of TGFβ type II receptor(TβRII) or integrin α_v in the NC cells inhibited functional activity of postnatal NC cells and also resulted in DDD under mechanical loading.Administration of RGD peptide, TGFβ, and α_vβ_6-neutralizing antibodies attenuated IVD degeneration. Thus,integrin-mediated activation of TGFβ plays a critical role in mechanical signaling transduction to regulate IVD cell function and homeostasis. Manipulation of this signaling pathway may be a potential therapeutic target to modify DDD. | Qin Bian Lei Ma Amit Jain Janet L Crane Khaled Kebaish Mei Wan Zhengdong Zhang X Edward Guo Paul D Sponseller Cheryle A Seguin Lee H Riley Yongjun Wang Xu Cao | 2017 | Bone Research2017，5，1： | 9 |
| 3 | Expression of co-stimulator 4-1BB molecule in hepatocellular carcinoma and adjacent non-tumor liver tissue,and its possible role in tumor immunity显示文摘AIM:To investigate the expression of 4-1BB molecule in hepatocellular carcinoma (HCC) and its adjacent tissues.METHODS:Reverse transcription-polymerase chain reaction (RT-PCR) was used to determine the gene expression of 4-1BB in hepatocarcinoma and its adjacent tissues,and peripheral blood mononuclear cells (PBMCs) from both HCC and health control groups.Flow cytometry was used to analyse the phenotypes of T cell subsets from the blood of HCC patients and healthy volunteers,and further to determine whether 4-1BB molecules were also expressed on the surface of CD4+ and CD8+ T cells. The localization of 4-1BB proteins on tumor infiltrating T cells was determined by direct immunofluorescence cytochemical staining and detected by confocal microscopy.RESULTS:4-1BB mRNA, which was not detectable in normal liver,was found in 19 liver tissues adjacent to tumor edge(<1.0cm).Low expression of 4-1BB mRNA was shown in 8 tumor tissues and 6 liver tissues located within 1 to 5cm away from tumor edge. In PBMCs, 4-1BB mRNA was almost not detected. Percentage of CD4^+, CD8^+ and CD3^+/CD25^+ T cells, as well as ratio of CD4 to CD8 revealed no difference between groups (P>0.05,respectively),while a significant lower percentage of CD3^+ T cell was found in HCC group as compared to healthy control group (P<0.05).However, 4-1BB molecules were almost not found on the surface of CD4+ and CD8+ T cells in HCC and healthy control group.Double-staining of 4-1BB^+/CD4^+ and 4-1BB^+/CD8^+ immunofluorescence on tumor infiltrating T cells was detected in 13 liver tissues adjacent to tumor edge (<1.0cm) by confocal microscopy.CONCLUSION: Although HCC may escape from immune attack by weak immunogenicity or downregulated expression of MHC-1 molecules on the tumor cell surface,tumor infiltrating T cells can be activated via other costimulatory signal pathways to exert a limited antitumor effect on local microenvironment. The present study also implicates that modulating 4-1BB/4-1BBL costimulatory pathway may be an effective immunotherapy strategy to augment the host response. | Wan, YL Zheng, SS Zhao, ZC Li, MW Jia, CK Zhang, H | 2004 | World Journal of Gastroenterology2004，10，2： | 6 |

| 5 | 新生儿继发于筛窦炎的眼眶脓肿(英文)显示文摘骨膜下脓肿是眼眶蜂窝织炎的一种,以脓和渗出液汇集在眼眶内骨膜下为特点。对于新生儿,眼眶脓肿非常罕见。我们报告1例年龄为26d的右眼患有严重眼眶蜂窝织炎的女患儿。眼眶和副鼻窦CT扫描显示右眼眶蜂窝织炎并内侧骨膜下和眼眶后部脓肿。眼分泌物培养见葡萄球菌生长,经用先锋霉素和甲硝唑静脉注射和经内窥镜鼻窦手术行急诊脓肿引流,恢复良好。通过内窥镜的鼻窦引流手术是预防更严重的并发症的首选治疗。 | C D Che Mahiran K Wan Mariny J Alagaratnam W H Wan Hazabbah | 2008 | 国际眼科杂志2008，8，4： | 2 |

| 7 | Efficient photon coupling from a diamond nitrogen vacancy center by integration with silica fiber显示文摘A central goal in quantum information science is to efficiently interface photons with single optical modes for quantum networking and distributed quantum computing.Here,we introduce and experimentally demonstrate a compact and efficient method for the low-loss coupling of a solid-state qubit,the nitrogen vacancy(NV)center in diamond,with a single-mode optical fiber.In this approach,single-mode tapered diamond waveguides containing exactly one high quality NV memory are selected and integrated on tapered silica fibers.Numerical optimization of an adiabatic coupler indicates that near-unity-efficiency photon transfer is possible between the two modes.Experimentally,we find an overall collection efficiency between 16%and 37%and estimate a single photon count rate at saturation above 700 kHz.This integrated system enables robust,alignment-free,and efficient interfacing of single-mode optical fibers with single photon emitters and quantum memories in solids. | Rishi N Patel Tim Schröder Noel Wan Luozhou Li Sara L Mouradian Edward H Chen Dirk R Englund | 2016 | Light(Science & Applications)2016，5，1： | 2 |
