BACKGROUND: A better understanding of the molecular mechanisms in liver regeneration holds promise for exploring the new potential therapy for liver failure. The present study was to investigate the role of zinc finger and BTB domain-containing protein 20(ZBTB20), a potential factor associated with liver regeneration, in a model of 70% hepatectomy in mice. METHODS: Parameters for liver proliferation such as liver/body ratio and BrdU positivity were obtained via direct measurement and immunohistochemistry. The levels of zinc fingers and homeoboxes 2(ZHX2), ZBTB20, alpha-fetoprotein(AFP) and glypican 3(GPC3) transcripts in the regenerating liver tissue of a 70% hepatectomy rodent model were monitored by real-time PCR analysis at different time points. Knockdown of ZBTB20 was performed to characterize its regulatory function. RESULTS: A negatively regulating relationship between ZHX2, ZBTB20 and AFP, GPC3 was revealed from 24 to 72 hours after 70% hepatectomy. ZBTB20 appears to negatively regulate AFP and GPC3 transcription since the knockdown of ZBTB20 promoted the proliferation of hepatocytes and the expression of AFP and GPC3. CONCLUSION: In addition to AFP, GPC3 and ZHX2, ZBTB20 is a new regulator in liver regeneration and the decrease of ZBTB20 expression following 70% hepatectomy promotes AFP and GPC3 expression.

Lhermitte-Duclos disease （LDD）, or dysplastic gangliocytoma of the cerebellum, is a rarehamartomatous lesion characterized by a slowly enlarging mass within the cerebellar cortex. The disease reveals unique appearance on magnetic resonance imaging （MRI）. Recognition of the imaging features makes the correct diagnosis possible even without a pathological examination. Three cases are presented and analyzed in this report.

To the Editor:Chest pain is one of the most common complaints for patients attending emergency departments(EDs)*** is important to accurately stratify risk of possible acute coronary syndrome(ACS)for these patients.[1]Several risk stratification scores such as thrombolysis in myocardial infarction(TIMI),global registry for acute coronary events(GRACE),Banach and HEART are helpful.[2]Previous research in our setting compared these four scores and found that the HEART score,with a C-statistic of 0.731,was the best for predicting 7-day major adverse cardiac events(MACE)The purpose of this study was to develop risk stratification prediction models for 7-day MACE in patients with chest pain,utilizing machine learning algorithms such as eXtreme Gradient Boosting(XGBoost),Support Vector Machine(SVM).

以广西来宾高层建筑测试项目中的一栋剪力墙结构为研究对象,在对其进行环境振动测试的基础上,依据现场实测模态数据对建立的结构有限元模型进行参数修正,评估结构的抗震性能.在Perform-3D中建立该高层结构的初始有限元模型,采用与PKPM设计模型相同的处理方式研究填充墙的影响,结构的模态周期计算结果表明,两类模型具有较好的可比性.通过在Perform-3D模型中添加斜撑单元对填充墙进行模拟,利用现场实测数据对斜撑单元的特征参数进行修正.对考虑和未考虑填充墙刚度影响的结构有限元模型分别进行了增量动力分析,评估潜在危险性水平地震作用下结构的整体抗震性能.结果表明,初始模型的最大层间位移角和顶层位移约为校验模型的1.1~1.4倍,最大基底剪力是校验模型的40%?60%.

目的通过观察两种无创通气模式成比例辅助通气（PAV）和双水平气道正压通气（BiPAP）对急性心源性肺水肿（ACPE）患者的通气反应、血流动力学等方面的变化规律，比较两者的治疗效果。方法选取广州医学院附属第二医院急诊科2008年5月至2009年4月收治的32例急性心源性肺水肿患者经常规治疗（强心、利尿、扩管、吸氧）0．5h无显效后，随机分成对照组、BiPAP组、PAV组。对照组继续按常规处理，BiPAP组、PAV组分别行常规治疗＋BiPAP通气和常规治疗＋PAV通气，检测三组患者治疗前和治疗后1h的血气分析、血压、心率、呼吸频率（RR）、氧合指数、呼吸困难缓解时间、视觉模拟评分（VAS评分）、辅助呼吸肌动用评分、气道峰压等指标，对比三种治疗方法在治疗前后各项指标的变化。结果经治疗1h后，三组间的RR、动脉血氧分压（PaO2）和氧合指数均较治疗前明显改善（P〈0．05），其中BiPAP组与PAV组较对照组的氧合指数、PaO2均升高（P〈0．05）、RR减低（P〈0．05）；BiPAP组与PAV组治疗后呼吸困难缓解的时问较对照组明显缩短（P〈0．05），治疗1h后PAV组患者的气道峰压较BiPAP组为低，差异具有统计学意义（P〈0．05），PAV组患者的舒适度相关指标（VAS评分、辅助呼吸肌动用评分）均较BiPAP组为低，差异具有统计学意义（P〈0．05）。结论无创PAV、BiPAP对改善急性心源性肺水肿患者氧合和缓解呼吸困难具有显著的临床疗效；PAV与BiPAP对ACPE患者的疗效相仿；PAV的同步性、舒适性较BiPAP好，气道峰压较低，更易被患者接受。
