Objective To investigate the molecular resistance mechanism of Escherichia coli HX43 by high-throughput sequencing. Methods HX43 was sequenced by the Illumina Miseq platform, and sequencing data were analyzed by the Edena, RAST, ResFinder, MLST and BLAST softwares and databases. Results HX43 was resistant to most common clinical antibiotics except carbapenems. Analysis of data revealed resistance genes to β-lactams (bla_CMY-42, bla_CTX-M-14 and bla_OXA-30), aminoglycosides (aac(3)-IIa, aadA5, strA, strB and aac(6′)-Ib-cr), quinolones (aac(6′)-Ib-cr), trimethoprim/sulfonamides(sul1, sul2 and dfrA17), tetracyclines (tet(B)), chloramphenicol (catB3 and cmlA1), macrolides(erm(B) and mph(A)). Sequence analysis of the contig containing bla_CMY-42 identified correlations of the gene with ISEcp1 insertion sequences, blc and sugE genes. Plasmid typing identified 5 plasmid incompatibility groups in HX43. MLST analysis found that HX43 belonged to ST3835, a relatively rare sequence type in the world. Conclusion Information of resistance genes can be obtained by high-throughput sequencing, which provides important experimental data for clinical antimicrobial treatment.

目的 探讨手动杠杆式胸外按压心肺复苏(CPR)装置对院内心肺复苏按压质量和复苏疲劳的影响。方法 将12名医学生志愿者分为手动杠杆式胸外按压CPR装置组(LDCPR)(n=6)和徒手标准CPR组(STCPR)(n=6)模拟院内心肺复苏场景进行CPR试验。LDCPR组采用手动杠杆式胸外按压CPR装置对模拟人进行连续6min连续胸外按压,STCPR组徒手对模拟人进行6min连续胸外按压。监测复苏期间按压的深度、频率以及按压者的心率和疲劳程度等变化。结果 随着连续胸外按压的进行,按压者的心率和疲劳程度都在不断增加,有效按压深度超过5 cm次数逐渐减少,但是在连续胸外按压的第4～6min,LDCPR组按压者的心率较STCPR组慢(P<0.05),疲劳程度较轻(P<0.05),有效按压的比例更高(P<0.05)。按压频率两组比较无明显差异。结论 在本模拟人试验中,手动杠杆式胸外按压CPR装置可减轻按压者疲劳,有助于提高院内CPR时长时间胸外按压的质量。

Objective We aimed to investigate simulated in-hospital cardiopulmonary resuscitation (CPR) quality and rescuer fatigue of external chest compression-only CPR by a manual leverage device(LDCPR). Methods All 12 volunteers (medical staffs: male 6 and female 6) were randomized to standard CPR by hand(STCPR)group (n=6)or LDCPR group(n=6). At STCPR group, continuous external chest compression-only was performed for 6 minutes to simulate in hospital cardiopulmonary resuscitation on a manikin; at LDCPR group, compression-only was performed for 6 minutes by a leverage device on a manikin. We measured blood pressure of the volunteers before and after performing each CPR technique, volunteers self-report fatigue scale and continuously monitored heart rate (HR) of the volunteers during each CPR technique by smart ring. CPR quality measures included chest compression rate and depth. Results During continuous external chest compression-only CPR, compressor's heart rate and fatigue scale were rising continuously, and percent of compress depth >5 cm were declining, too.Compressor's heart rate and fatigue scale were higher in the STCPR group than in the LDCPR group (P<0.05) during the fourth to sixth minutes CPR (P<0.05). Percent of compress depth > 5 cm was higher in the LDCPR group than in the STCPR group (P<0.05) during the fourth to sixth minutes of CPR (P<0.05).Compress rate had not differed between the 2 groups during CPR. Conclusion In the manikin study, manual leverage external chest compress device may reduce fatigue scale and improve long term compression quality during in-hospital cardiopulmonary resuscitation.

Objective To detect myocardial longitudinal strain in the area supplied by left anterior descending coronary artery (LAD) via two dimensional speckle tracking image (2D-STI), and to investigate its estimated value of myocardial systolic function of ischemic myocardium. Methods Detection of myocardial longitudinal strain parameters in the area supplied by the LAD with different stenosis degree(＜50%、50%~75%、＞75%) and no definite stenosis via 2D-STI:subendocardial longitudianl strain (LS-endo), subepicardial longitudianl strain (LS-epi) and territorial longitudianl strain (LS-Territorial). Calculate transmural longitudinal strain (LS-mural) in the systole.Then observe the changes of myocardial longitudinal strain in the blood supply area after percutaneous coronary interventional therapy (PCI). Results LS-endo, LS-epi, LS-Territorial and LS-mural gradually decrease with the increase of LAD stenosis (all P<0.01).

Conclusion Layer-specific quantification of myocardial longitudinal strain by 2D-STI may reveal the regional myocardial systolic function. It is useful to identify the ischemic myocardium in the early stage and evaluate the treatment effect of PCI.
