摘 要:目的探讨血浆心房利钠肽(ANP)、内皮素(ET)-1、血管性假血友病因子(vWF)水平在西地那非治疗新生儿持续性肺动脉高压(PPHN)过程中的变化及意义。方法选取PPHN患儿66例(PPHN组)应用西地那非治疗,分别于治疗前和治疗3、7d后采用彩色多普勒超声测定肺动脉收缩压(PASP),并同时检测动脉血气和右手指脉搏血氧饱和度(SpO2),再同时采集静脉血应用酶联免疫吸附法检测ANP、ET-1和vWF水平。各指标与除外心肺相关疾病的非PPHN患儿40例(对照组)进行比较。结果PPHN组治疗前PASP、SpO2、动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO,)及血浆ANP、ET-1、vWF水平[(66.5±13.4)mmHg(1mm Hg=0.133kPa)、0.726±0.531、(46.3±7.2)mmHg、(59.2±7.4)mmHg、(272.6±20.3)ng/L、(221.3±24.3)ng/L、(142.5±20.3)%]与对照组[(25.0±6.2)mmHg、0.896±0.767、(88.3±7.6)mmHg、(41.1±6.1)mmHg、(68.4±7.9)ng/L、(39.8±6.5)ng/L、(95.3±18.5)%]比较差异有统计学意义(P〈0.05);PPHN组治疗3d后各指标[(48.3±3.2)himHg、0.841±0.416、(73.6±9.3)mmHg、(50.5±7.2)InmHg、(102.6±20.3)ng/L、(79.6±15.2)ng/L、(103.6±14.1)%]均明显改善,与治疗前和对照组比较差异有统计学意义(P〈0.05),治疗7d后各指标[(25.2±3.6)mmHg、0.882±0.724、(85.4±7.4)mmHg、(40.2±6.4)mmHg、(64.4±3.6)ng/L、(37.3±5.4)ng/L、(92.9±11.7)%]均较治疗3d后明显改善,差异有统计学意义(P〈0.05),与对照组比较差异无统计学意义(P〉0.05)。直线相关分析结果显示,治疗前及治疗3、7d后ANP、ET-1、vWF与PASP、PaCO2分别呈显著正相关(P〈0.01),ANP、ET-1、vWF与SpO2、PaO2分别呈显著负相关(P〈0.01)。以心脏超声�Objective To study the changes and significance of plasma atrial natriuretic peptide (ANP) ,endothelin-1 (ET-1),yon Willebrand factor (vWF) levels in newborns with persistent pulmonary hypertension (PPHN) after the treatment of sitdenafil. Methods Sixty-six cases with PPHN group and 40 cases with non-PPHN (control group) were enrolled. PPHN group was in the treatment of sildenafil. Collected the blood when before the treatment of sildenalil and 3,7 d after treatment, respectively. Arterial blood gas were done and pulmonary arterial systolic pressure (PASP) was measured before treatment and 3,7 d after treatment, and by the same time recording pulse oxygen saturation (SpO2). Plasma ANP, ET-I,vWF levels were measured by ELISA method. Results The levels of PASP,SpO2 arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide (PaCO2) and plasma ANP,ET-1 ,vWF in PPHN group before treatment [(66.5 ± 13.4)mm Hg (1 mm Hg = 0.133 kPa),0.726 ±0.531, (46.3 ±7.2)mm Hg, (59.2 ± 7.4) mm Hg, (272.6 ± 20.3 )ng/L, (221.3 ± 24.3 ) ng/L, ( 142.5 ± 20.3)% ] compared with control group [(25.0 ± 6.2) mm Hg,0.896 ± 0.767, (88.3 ± 7.6) mm Hg, (41.1 ± 6.1 )mm Hg, (68.4 ± 7.9) ng/L, (39.8 ± 6.5 ) ng/L, (95.3 ± 18.5 )%] were statistically significant(P 〈 0.05 ). Their levels in PPHN group 3 d after treatment [ (48.3 ± 3.2) mm Hg, 0.841 ± 0.416, (73.6 ± 9.3 )mm Hg, (50.5± 7.2) mm Hg, ( 102.6 ± 20.3) ng/L, (79.6 ± 15.2) ng/L, (103.6 ± 14.1)% ] were significantly improved,there was significant difference compared with before treatment and control group (P 〈 0.05 ). Their levels in PPHN group 7 d after treatment [ (25.2 ± 3.6) mm Hg,0.882 ± 0.724, (85.4 ± 7.4) mm Hg, (40.2 ±6.4) mm Hg, (64.4 ± 3.6) ng/L, (37.3 ±5.4)ng/L, (92.9 ± 11.7)% ] were significantly improved,there was significant difference compared with 3 d after treatment (P 〈 0.05
