简介:摘要急性冠状动脉综合征(ACS)根据患者发作时心电图有无ST段抬高,分为急性ST段抬高型心肌梗死(STEMI)和非ST段抬高型ACS(NSTE-ACS)。部分患者在冠状动脉急性闭塞时并不出现ST段抬高,而是呈现其他心电图异常,其中表现为前壁ST段上斜型压低伴T波高尖的心电图改变者,称为de Winter心电图改变。本文就de Winter心电图改变的最新认识作一综述。
简介:摘要:近年来,我国开始大力推广节能低碳建筑,国家对建筑节能要求的逐步提高。DE烧结淤泥砖作为一种工业废料烧结而成的绿色建材,在公共建设和部分住宅项目中开始逐渐推广。且它以其抗剪强度高、抗裂和抗渗性能好、具有保温性能的主要特性在项目建设中具有一定的优势。文章结合上海韵意11-02地块集中商业项目墙体施工实例,验证了新型墙体保温材料-DE烧结淤泥砖的主要特性,以及DE烧结淤泥砖在工程项目应用中的主要优势与缺点。为工程中烧结淤泥砖的选用与施工提供参考。
简介:摘要目的分析呈de Winter型心电图改变的急性心肌梗死(AMI)患者的临床特征。方法连续收集北京潞河医院2017年6月至2019年1月经胸痛绿色通道收治的AMI患者1 287例。分析呈de Winter型心电图改变的13例患者的心电图特点、临床特征,并与206例前壁ST段抬高型心肌梗死(STEMI)患者进行比较。结果13例患者中男性12例,年龄(52.23±12.55)岁。与前壁STEMI患者相比,de Winter组年龄较小[(52.23±12.55)岁比(59.79±12.46)岁;t=-2.12,P=0.03],从发病至出现典型心电图的时间较短[109.0(71.5, 152.0)min比200.5(120.0, 397.5)min;Z=-3.38,P<0.01]。3例患者de Winter型心电图与STEMI心电图发生了相互演变,其中2例患者心电图由de Winter型演变成STEMI,1例患者由STEMI演变成de Winter型后再次演变成STEMI。冠状动脉造影示,11例罪犯血管为左前降支(LAD)近段,1例为LAD中段,1例为三支血管弥漫痉挛。13例患者在急诊冠状动脉造影或经皮冠状动脉介入治疗后de Winter心电图均改变消失。结论de Winter型心电图常预示着LAD近中段病变,de Winter型心电图可以和STEMI心电图相互演变,应及早识别并行血运重建。

简介:AbstractBackground:Although de novo stage IV breast cancer is so far incurable, it has entered an era of individualized treatment and chronic disease management. Based on systemic treatment, whether the surgical resection of primary or metastatic foci of de novo stage IV breast cancer can bring survival benefits is currently controversial. We aimed to explore the clinicopathological factors and current status of the management of de novo stage IV breast cancer in China to provide a reference for clinical decisions.Methods:Based on the assistance of Chinese Society of Breast Surgery, a retrospective study was conducted to analyze the clinical data of patients with de novo stage IV breast cancer in 33 centers from January 2017 to December 2018. The relationship between basic characteristic (age, menstrual status, family history, reproductive history, pathological type, estrogen receptor [ER] status, progesterone receptor [PR] status, human epidermal growth factor receptor 2 [HER2] status, Ki-67 percentage, and molecular subtype), and metastasis sites (lung metastasis, liver metastasis, and bone metastasis) was examined by Pearson Chi-square tests.Results:A total of 468 patients with de novo stage IV breast cancer were enrolled. The median age of the enrolled patients was 51.5 years. The most common pathological type of primary lesion was invasive carcinoma (97.1%). Luminal A, luminal B, HER2 overexpressing, and triple-negative subtypes accounted for 14.3%, 51.8%, 22.1%, and 11.8% of all cases, respectively. Age, PR status, and HER2 status were correlated with lung metastasis (χ2= 6.576, 4.117, and 8.643 and P = 0.037, 0.043, and 0.003, respectively). Pathological type, ER status, PR status, and molecular subtype were correlated with bone metastasis (χ2 = 5.117, 37.511, 5.224, and 11.603 and P = 0.024, <0.001, 0.022, and 0.009, respectively). Age, PR status, HER2 status, Ki-67 percentage, and molecular subtype were correlated with liver metastasis (χ2= 11.153, 13.378, 10.692, 21.206, and 17.684 and P= 0.004, <0.001, 0.001, <0.001, and 0.001, respectively). Combined treatment with paclitaxel and anthracycline was the most common first-line chemotherapy regimen for patients with de novo stage IV breast cancer (51.7%). Overall, 91.5% of patients used paclitaxel-containing regimens. Moreover, 59.3% of hormone receptor-positive patients underwent endocrine therapy.Conclusions:In 2018, 1.07% of patients from all studied centers were diagnosed with de novo stage IV breast cancer. This study indicated that 95.1% of patients received systemic therapy and 54.2% of patients underwent surgical removal of the primary lesion in China.
简介:摘要分析2019年3月遵义医科大学附属医院收治的Cornelia de Lange综合征(CdLs)患儿2例的临床资料及基因变异结果。2例均在婴儿期起病,表现为难治性癫痫,均伴发育落后及特殊外貌,基因检测显示X染色体上SMC1A基因突变,例1为c.2561dupA(p.K854fs)移码突变;例2为c.3441+1G>A(exon24)剪接突变,均为新生杂合突变,位点未见文献报道。2例患儿为SMC1A基因突变所致CdLs,进一步扩大了CdLs的基因型。提示对于早期癫痫起病伴特殊外貌及发育落后的患儿需考虑CdLs的可能,必要时需行基因检测。
简介:摘要目的对1例疑诊为Cornelia de Lange综合征的引产儿及其亲代进行基因检测,为遗传咨询和产前诊断提供依据。方法详细询问妊娠史及家族史,结合孕期影像学检查及引产儿表型做出临床诊断。收集引产儿组织及其亲代的静脉血样,提取基因组DNA,进行全外显子组测序分析,筛查与表型相关的变异位点,并通过Sanger测序进行验证。结果孕期超声提示胎儿前臂及手形态异常、小脑蚓部发育不良、下颌偏小、双肾实质回声增强,引产后可见上肢及面部畸形。全外显子组测序提示胎儿携带NIPBL基因c.2118delG(p.Lys706fs)杂合移码变异,其父母未检出相同变异。结论NIPBL基因c.2118delG杂合移码变异可能是胎儿的致病原因。上述结果可为家系遗传咨询及指导再生育提供依据。
