血管内超声指导药物洗脱支架置入对合并慢性肾脏病患者长期预后的影响:ULTIMATE CKD亚组分析

目的评估血管内超声(IVUS)指导药物洗脱支架(DES)置入对慢性肾脏病(CKD)患者长期临床结局的影响。方法研究对象来源于ULTIMATE研究,该研究是一项前瞻性、多中心、随机对照研究,从2014年8月到2017年5月在国内8家中心入选1448例置入DES的冠心病患者,按1∶1的比例随机分为两组(接受IVUS或冠状动脉造影指导支架置入)。本研究选取ULTIMATE研究中有基线血肌酐值的患者1443例,分为CKD组和非CKD组。CKD的定义为Cockcroft-Gault(CG)公式得出的估算的肾小球滤过率(eGFR)<60 ml·min^-1·1.73 m^-2至少3个月。主要终点是术后3年靶血管失败(TVF),包含心原性死亡、靶血管心肌梗死和临床症状驱动的靶血管血运重建。采用Kaplan-Meier法进行生存分析,通过log-rank检验比较各组的终点事件发生情况,并采用Cox风险比例模型计算HR及其95%CI,同时检验交互作用。采用多因素Cox回归分析TVF的独立影响因素。结果本研究共入选1443例置入DES的冠心病患者,其中CKD组349例(24.2%),非CKD组1094例。CKD组中采用IVUS指导支架置入者180例,造影指导支架置入者169例;非CKD组中采用IVUS指导支架置入者543例,造影指导支架置入者551例。3年临床随访率为98.3%(1418/1443)。术后3年时,CKD组的TVF发生率为12.0%(42/349),高于非CKD组的7.4%(81/1094)(P=0.01),其差异主要来源于CKD组更高的心原性死亡率[4.6%(16/349)比1.5%(16/1094),P<0.001]。CKD组中IVUS指导下置入支架者的TVF发生率低于造影指导下置入支架者[8.3%(15/180)比16.0%(27/169),P=0.03]。而非CKD组共81例发生TVF,其中IVUS指导下置入支架者的TVF发生率与造影指导下置入支架者差异无统计学意义[5.9%(32/543)比8.9%(49/551),P=0.06],不存在交互作用(P=0.47)。多因素Cox回归分析结果显示,IVUS指导(HR=0.56,95%CI 0.39~0.81,P=0.002)、CKD(HR=1.83,95%CI 1.17~2.87,P=0.010)和支架长度(每增加10 mm)(HR=1.11,95%CI 1.04~1.19,P=0.002)是置入DES术后3年发生TVF的独立影响因素。结论对于置入DES的冠心病患者,合并CKD者术后3年的TVF发生风险高于非CKD患者;相比于冠状动脉造影,IVUS指导DES置入可以降低CKD患者的TVF风险。

Genetic diversity of VP3 of goose parvovirus isolated from Southeastern China during 2012–2013

Although vaccine and passive immunotherapy were widely used to prevent goose parvovirus (GPV) infection in goose industry, GPV still poses a big problem in Southeastern China. In this study, 23 GPV isolates were isolated from goslings suspected with GPV infection in Southeastern China during 2012–2013, and the genetic diversity of VP3 of GPV was analyzed. Phylogenetic tree revealed that these isolates could be clustered into two groups, and 11 of 23 could be further clustered into a new subgroup. Moreover, eight novel mutations and seventeen conserved amino acids were found in these 23 isolates in comparison with isolates previously deposited in GenBank. These isolates and findings not only provide insights into the etiology and molecular characteristics of GPV endemic in Southeastern China, but also enrich the GPV genetic information for better controlling the disease.     

miR-21反义寡核苷酸增强地西他滨体外抗白血病效应

目的:研究miR-21反义寡核苷酸(anti-miR-21 oligonucleotide,AMO)对地西他滨(decitabine,DCA)抗白血病效应的影响及可能机制。方法:将AMO和无义寡核苷酸(scramble oligonucleotide,SCR)通过脂质体转染导入HL-60细胞,实时荧光定量PCR(real-time PCR)验证转染效率,再分别与DCA 0.5、2.0和4.0μmol/L作用48 h。Real-time PCR分别检测人周期节律蛋白3(h Per3)mRNA表达,Annexin V/PI法检测凋亡,流式细胞术检测CD117和CD11b平均荧光强度(MFI)。结果:AMO转染组miR-21表达(0.35±0.07)低于空白组(0.71±0.07)和SCR转染组(0.66±0.05),差异有统计学意义(P0.05)。AMO转染组的HL-60细胞DCA的IC50低于空白组和SCR转染组(P0.01)。同一浓度下,AMO组的早期凋亡率、CD11b的MFI和h Per3 mRNA均高于同一浓度药物作用的空白组和SCR组,CD117 MFI均低于同一浓度药物作用的空白组和SCR组,差异均具有统计学意义(P0.01)。结论:AMO能显著促进DCA体外抗白血病效应,其机制可能与其协助激活h Per3的表达有关。
