Description
发明领域
本发明涉及医用配制品,具体涉及含有来自冬青科植物的未确定结构的中药制剂,该药物制剂适用于治疗H1N1流感引起的病毒性肺损伤。
技术背景
流感病毒引致的呼吸道病毒感染(Respiratory virus infection,RVI)具有高传染性、高变异性的特点,疫苗免疫难以达到完全的防护作用,并且近年来发该病发病率不断升高。而RVI发展为急性肺损伤(Acute lung injury,ALI)和急性呼吸窘迫综合征(AcuteRespiratory Distress Syndrome,ARDS)是临床导致死亡的主要原因,由于其危重性、高死亡率的特点,一直是危急重病症的研究热点和难点。因此RVI-ALI的相关机制研究和治疗药物研发一直是本学科前沿的热点问题。而病毒性肺损伤是指由呼吸道病毒严重感染引起的急性肺损伤(acute lung injury,ALI),临床主要表现为急性进行性加重的呼吸困难和难治性低氧血症,进一步发展可演变为急性呼吸窘迫综合征(acute respiratory distresssyndrome,ARDS),出现急性、进行性缺血性呼吸衰竭,为临床常见的危重症。近年来对ALI以及ARDS的认识逐渐发展到对炎症、免疫调控的认识。大量实验和临床证据表明,重度病毒感染可以引起机体内各种细胞因子大量产生,机体促炎和抗炎细胞因子严重失衡,形成细胞因子风暴,通常以肺为靶器官,造成急性肺损伤,从而引发ALI甚至ARDS。
中医观念认为急性肺损伤是由肺通调水道功能失司至水液内停。在用药时根据上早期宜用通腑泻下类和清热解毒类药物,辅助使用益气活血类药物,病情缓解后,继续清热解毒,逐渐增加益气养阴等药物,减轻病人的痛苦,降低急性肺损伤疾病的死亡率。
中医药治疗病毒感染引起的肺损伤(RVI-ALI)有广泛的临床和实验基础,多项研究从现代药理学和分子生物学角度,证明了中医药治疗呼吸道病毒的有效性表现在调节机体免疫功能,重建促炎和抗炎细胞因子平衡,协调细胞因子的释放,阻断炎性介质的瀑布反应。中药针对病毒感染的不同阶段,多个层面,多个环节,多个部位发挥治疗作用,特别是多靶点作用对比西医药有着不可低估的独特优势。而且中医药是我国独具民族特色的科学领域,其可能存在新的作用机制或靶点。
近几年的实验报道中抗病毒中药实验研究的主要对象可涉及:单味中草药,如:败酱草、熟大黄、丹参等。单味药的有效成分,如:汉防己甲素、穿琥宁、莪术油、人参多糖等。经典成方加减的煎剂,如麻杏石甘汤加味的清肺饮;柴胡桂枝汤加杏仁、瓜蒌、牛蒡子、大黄、赤芍方;银翘散、桂枝麻黄各半汤、新加香薷饮、桂枝汤、升降散等。较成熟的临床制剂,如清肺口服液、青蚤颗粒、四合一口服液、感冒康宁颗粒、柴芩感冒药、熊胆牛黄胶囊、炎康颗粒剂、退热微型灌剂、众生丸、双黄连粉针剂、蛭丹化瘀口服液等。中药制剂与抗病毒西药的联合应用,如柴胡注射液、护肺口服液或穿琥宁分别与病毒唑联合应用等。
面对日益严峻的流感疫情,发挥传统中医药的优势,通过科学筛选和药效评价,对岭南医家防治流感的临床经验进行发掘,发现防治呼吸道感染的创新药物,开发具有中医药特色的治疗病毒性肺损伤的复方药物具有重大的现实意义。
