简介：摘要目的了解新型狂犬疫苗“2-1-1”接种程序的临床应用效果，为新的接种方法积极推进进行前瞻性研究。方法对本社区2011年10月-2013年12月148例被被狗、猫、鼠等动物咬、抓伤人群进行按照就诊的先后顺序平均分为2组，观察组74例，实施“2-1-1”接种程序；对照组74例实施传统的“五针次法”接种程序。在接种程序中10d和接种程序结束后15d分别对患者进行血清抗狂犬病毒抗体水平进行统计比较，并进一步观察其影响因素。结果观察组与对照患者10d血清抗狂犬病毒抗体阳性率分别为56.76%、12.16%；接种程序完成后15d血清抗狂犬病毒抗体阳性率分别为97.30%、85.14%。抗体转阳率与年龄增长呈负相关。结论“2-1-1”狂犬疫苗接种程序完全符合药物动力学原理，它能迅速提高机体内血药浓度，并在短期内产生抗体，同时也减少患者就诊次数，更加方便患者。但疫苗的接种效果与患者各机体个体差异存在一定的联系，全程接种15d后应加强抗体水平的检测，如抗体阴性患者应积极寻找原因及加强接种。

简介：摘要肺鳞癌目前治疗方式仍局限于传统的手术及放化疗，探究新的治疗方向极为重要，分子靶向基因的研究可能为肺鳞癌治疗带来突破。ROS1阳性肺癌绝大多数为肺腺癌，肺鳞癌阳性者罕见，基于报道我院收治的1例ROS1阳性肺鳞癌患者，同时检索目前国内外相关报道，对肺鳞癌患者进行ROS1检测的必要性及靶向药物克唑替尼治疗ROS1阳性的肺鳞癌的可能进行分析，为肺鳞癌的靶向治疗探索提供一种新的思路。

简介：AbstractBackground:Emerging evidence indicates that the sineoculis homeobox homolog 1-eyes absent homolog 1 (SIX1-EYA1) transcriptional complex significantly contributes to the pathogenesis of multiple cancers by mediating the expression of genes involved in different biological processes, such as cell-cycle progression and metastasis. However, the roles of the SIX1-EYA1 transcriptional complex and its targets in colorectal cancer (CRC) are still being investigated. This study aimed to investigate the roles of SIX1-EYA1 in the pathogenesis of CRC, to screen inhibitors disrupting the SIX1-EYA1 interaction and to evaluate the efficiency of small molecules in the inhibition of CRC cell growth.Methods:Real-time quantitative polymerase chain reaction and western blotting were performed to examine gene and protein levels in CRC cells and clinical tissues (collected from CRC patients who underwent surgery in the Department of Integrated Traditional and Western Medicine, West China Hospital of Sichuan University, between 2016 and 2018, n = 24). In vivo immunoprecipitation and in vitro pulldown assays were carried out to determine SIX1-EYA1 interaction. Cell proliferation, cell survival, and cell invasion were determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, clonogenic assay, and Boyden chamber assay, respectively. The Amplified Luminescent Proximity Homogeneous Assay Screen (AlphaScreen) method was used to obtain small molecules that specifically disrupted SIX1-EYA1 interaction. CRC cells harboring different levels of SIX1/EYA1 were injected into nude mice to establish tumor xenografts, and small molecules were also injected into mice to evaluate their efficiency to inhibit tumor growth.Results:Both SIX1 and EYA1 were overexpressed in CRC cancerous tissues (for SIX1, 7.47 ± 3.54 vs.1.88 ± 0.35, t = 4.92, P = 0.008; for EYA1, 7.61 ± 2.03 vs. 2.22 ± 0.45, t = 6.73, P = 0.005). The SIX1/EYA1 complex could mediate the expression of two important genes including cyclin A1 (CCNA1) and transforming growth factor beta 1 (TGFB1) by binding to the myocyte enhancer factor 3 consensus. Knockdown of both SIX1 and EYA1 could decrease cell proliferation, cell invasion, tumor growth, and in vivo tumor growth (all P < 0.01). Two small molecules, NSC0191 and NSC0933, were obtained using AlphaScreen and they could significantly inhibit the SIX1-EYA1 interaction with a half-maximal inhibitory concentration (IC50) of 12.60 ± 1.15 μmol/L and 83.43 ± 7.24 μmol/L, respectively. Administration of these two compounds could significantly repress the expression of CCNA1 and TGFB1 and inhibit the growth of CRC cells in vitro and in vivo.Conclusions:Overexpression of the SIX1/EYA1 complex transactivated the expression of CCNA1 and TGFB1, causing the pathogenesis of CRC. Pharmacological inhibition of the SIX1-EYA1 interaction with NSC0191 and NSC0933 significantly inhibited CRC cell growth by affecting cell-cycle progression and metastasis.

简介：摘要帕金森病(PD)是世界上第二常见的神经退行性疾病，它的发病机制与线粒体功能障碍、氧化应激反应以及钙稳态失衡有关。近年来，PD与Ca2+的关系成为研究热点，钙稳态失衡可通过不同的途径导致PD。细胞内Ca2+水平取决于钙库操纵性钙内流(SOCE)，而SOCE由钙释放激活钙通道调节分子1(Orai1)、基质相互作用分子1(STIM1)及瞬时受体电位通道1(TRPC1)相互作用组成的功能复合体调节。常见的PD神经毒素可通过降低Orai1-STIM1-TRPC1复合体功能，损伤SOCE及其下游的信号通路选择性损伤多巴胺能神经元，并且Orai1-STIM1-TRPC1复合体可能通过作用于小胶质细胞以及内质网调控神经炎症、自噬现象以影响PD的发生发展。因此恢复Orai1-STIM1-TRPC1复合体表达及功能，维持钙稳态可能成为PD的有效治疗靶点。
