目的 观察超声心动图(UCG)+心肌损伤标志物水平检测在急性心肌梗死(AMI)患者诊断中的应用价值。方法 选取2020年6月—2021年9月我院收治的74例AMI患者为观察组,另选取同期65例疑似AMI患者为对照组,2组均进行UCG检测,并对比入院后0~2 h、2~12 h、12~24 h心肌损伤标志物[肌酸激酶同工酶(CK-MB)、氨基末端脑钠肽前体(NT-proBNP)、肌钙蛋白(cTnI)、心脏型脂肪酸结合蛋白(H-FABP)]水平,分析心肌损伤标志物与AMI病情程度的关联性及UCG+心肌损伤标志物水平检测对AMI诊断的应用价值。结果 UCG检查结果显示观察组阳性率86.79%高于对照组9.23%(P＜0.001);对照组入院后各时间段CK-MB、NT-proBNP、cTnI、H-FABP水平差异无统计学意义(P＞0.05)观察组入院后各时间段CK-MB、NT-proBNP、cTnI、H-FABP水平均高于对照组(P＜0.05);Spearman相关分析可知,血清CK-MB、NT-proBNP、cTnI、H-FABP水平与AMI患者病情程度呈正相关(r₁=0.648,r₂=0.692,r₃=0.704,r₄=0.683,P＜0.05);受试者工作特征曲线(ROC)曲线分析显示,UCG+血清CK-MB、NT-proBNP、cTnI、H-FABP联合检测对AMI患者的诊断敏感度(85.14%)、特异度(100.00%)较高(P＜0.05)。结论 UCG+心肌损伤标志物水平检测应用于AMI患者有利于提高诊断敏感度、特异度,诊断价值较高。

目的 研究放射性 ¹³¹I 在甲亢伴甲状腺结节中的应用价值。方法 纳入我院90例甲亢患者,根据其是否伴甲状腺结节分为无结节组(51例)、结节组(39例),均接受放射性 ¹³¹I 治疗。比较两组治疗总有效率,分析两组治疗前后血清甲状腺过氧化物酶抗体(TPOAb)、甲状腺球蛋白抗体(TGAb)、促甲状腺激素(TSH)、游离三碘甲腺原氨酸(FT3)及游离甲状腺素(FT4)水平。结果 无结节组治疗总有效率74.51%,结节组为58.97%,差异无统计学意义(P＞0.05);两组治疗后TSH均高于治疗前(P＜0.05),FT3、FT4均低于治疗前(P＜0.05),TPOAb、TGAb较治疗前比较差异均无统计学意义(P＞0.05);无结节组治疗后FT3、FT4低于结节组(P<0.05),TPOAb、TGAb、TSH较结节组比较差异均无统计学意义(P＞0.05)。结论 放射性 ¹³¹I 治疗甲亢伴甲状腺结节效果好,且操作简单,副作用少,值得临床推广使用。

Objective To study the value of radioactivity ¹³¹I in hyperthyroidism with thyroid nodules. Methods Ninety patients with hyperthyroidism in our hospital were divided into non-nodule group (51 cases) and nodule group (39 cases) according to whether they had thyroid nodules or not. All patients received ¹³¹I radiation therapy. The total effective rate was compared between the two groups. The serum levels of thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) were analyzed before and after treatment. Results The total effective rate was 74.51% in non-nodule group and 58.97% in nodule group, with no significant difference (P>0.05);after treatment, TSH was higher in both groups than that before treatment (P<0.05), FT3 and FT4 were lower than that before treatment (P<0.05), TPOAb and TGAb had no significant difference compared with that before treatment (P>0.05);FT3 and FT4 in nodule-free group were lower than those in nodule group (P<0.05). TPOAb, TGAb and TSH had no significant difference compared with nodule group (P>0.05). Conclusion Radioactive ¹³¹I treatment of hyperthyroidism with thyroid nodules has good effect, simple operation and few side effects, which is worthy of clinical application.

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.

目的 探讨良性前列腺增生(BPH)并急性尿潴留(AUR)后血清肌酐、前列腺特异抗原(PSA)及其膀胱尿道功能的相关性及其临床意义。方法 对随机选择的36例已留置尿管48h以上的BPH并AUR患者进行尿流动力学检查,且同日行血清肌酐、PSA检测并分为两组:DI(逼尿肌不稳定)组(22例)和无DI组(14例),分析血清肌酐、PSA与膀胱功能各因素的相关性。结果 36例患者中逼尿肌收缩力很弱(VW)占10例,其游离PSA(fPSA)均<1.0 ng/mL,DI组中血清肌酐与膀胱顺应性、总PSA(tPSA)有相关性(r分别为0.406、-0.340,P值分别<0.01、0.05);DI幅度与膀胱顺应性、逼尿肌收缩力、tPSA有相关性(r分别为-0.309、0.677、0.304,P值分别<0.05、0.01、0.05);DI组与无DI组的fPSA与逼尿肌收缩力均有相关性(r分别为0.375、0.464,P值均<0.05)。DI组血清肌酐与fPSA、DI幅度、逼尿肌收缩力无相关性(r分别为-0.282、-0.301、-0.184,P值均>0.05);无DI组tPSA与血清肌酐、膀胱顺应性、逼尿肌收缩力无相关性(r分别为0.278、0.348、0.365,P值均>0.05)。结论 BPH并AUR患者的血清fPSA越低(<1.0 ng/mL),间接反映逼尿肌收缩力受损越严重,DI影响tPSA及肌酐水平。
