研究目的:

研究N-乙酰半胱氨酸(N-acetylcysteine,NAC)对胆道闭锁患儿葛西术前术后的疗效及其机理  

Objectives of Study:

Study the effect and mechanism of N-acetylcysteine (NAC) on children with biliary atresia before and after Kassai operation

药物成份或治疗方案详述:

治疗方案:招募满足纳入和排除标准的80例BA患者,分组如下,1)BA术前用药组20例;2)BA术前不用药组20例;3)BA术后用药组20例;4)BA术后不用药组20例。对术前组的受试者在术前一周开始用药,静脉注射NAC(用药剂量:NAC 150mg/kg/天,即每个患儿每天使用5ml NAC溶于30ml10%糖)1周,每天一次。对术后组的受试者在术后48小时后开始用药,按上述剂量连续两周静脉滴注NAC,每天一次。检测用药前后患儿血常规、肝功能、外周血中CD177细胞比例及胞内活性氧的生成、线粒体及中性粒细胞胞外诱捕网的表达等来判断疗效。 

Description for medicine or protocol of treatment in detail:

Treatment plan: 80 BA patients who met the inclusion and exclusion criteria were recruited. The groups were as follows: 1) 20 BA patients with NAC before Kassai operation; 2) 20 BA patients without NAC before Kassai operation;3) 20 BA patients with NAC after Kassai operation; 4) 20 BA patients without NAC after Kassai operation. Patients in the preoperative group were treated with NAC (dosage: NAC 150mg / kg / day, i.e. 5ml NAC dissolved in 30ml 10% Glucose solution per day) for 1 week, once a day. Patients in the postoperative group were given NAC intravenously once a day for two consecutive weeks after 48 hours.To evaluate the efficacy of NAC, blood routine test, liver function, the proportion of CD177 cells in peripheral blood and the expression of reactive oxygen species, mitochondria and neutrophil extracellular traps of CD177 cells were detected before and after treatment with NAC. 

纳入标准:

1.进行葛西手术时的年龄小于或等于90天的胆道闭锁患儿
2.患儿症状及体征、术前检测(B超、肝功能等)和胆道造影诊断为胆道闭锁的患儿
3.患儿的法定监护人在了解本研究的风险和研究性质后签署知情同意书

Inclusion criteria

1.Age less than or equal to 90 days at time of Kasai Portoenterostomy
2.Children diagnosed as biliary atresia by Symptoms and signs and preoperative examination (B-ultrasound, liver function) and Cholangiography
3.The legal guardian signs a consent form after understanding the risks and nature of the research

排除标准:

1、尽管应用了维生素K,肝脏功能仍然处于失代偿期(INR >1.3)
2、呼吸道感染急性期
3、肾功能不全
4、有严重的先天性或后天性肺部疾病、神经系统疾病、心血管疾病、代谢性疾病、内分泌疾病和肾脏疾病等,可能会干扰研究的进展和结果

Exclusion criteria:

1. Decompensated liver disease (INR >1.3) despite parenteral Vitamin K administration)
2. Active respiratory infections
3. Renal insufficiency
4. There are serious complication, such as congenital or acquired lung diseases, neurological diseases, cardiovascular diseases, metabolic diseases, endocrine diseases and kidney diseases, which may interfere with the progress and results of the research
