目的观察卡介菌多糖核酸(SQK)穴位注射防治小儿反复呼吸道感染(RRI)的疗效及其对生长发育的影响。方法应用SQK足三里穴位注射3个月～1年的治疗,观察预防RRI的疗效、副作用及其对身高和体重的月增长率的影响。结果 92例RRI患儿经SQK穴位注射治疗,显效率为83.7%,总有效率为95.7%。经过2个疗程以上治疗的显效率为92.3%,总有效率为100%。92例RRI患儿经SQK穴位注射治疗后身高和体重的月增长率明显高于正常儿童,P<0.05。第一疗程的身高和体重月增长率明显高于第三、第四疗程的身高和体重的月增长率,P<0.05。结论卡介菌多糖核酸足三里穴位注射疗法,在显著提高RRI患儿免疫功能的同时,还能加速其身高和体重的增长速率,改善生长发育落后状况,无明显不良反应。
Objective To observe the curative effect of the injection of BCG polysaccharides nucleic acid (SQK) on children with recurrent respiratory tract infection (RRI) and its effect on growth and development. Methods The SQK acupoints at Zusanli Point were treated by three-month to one-year treatment. The therapeutic effects, side effects and their effects on the monthly growth rate of height and body weight were observed. Results 92 cases of RRI children treated by SQK point injection, markedly effective rate was 83.7%, the total effective rate was 95.7%. After 2 courses of treatment markedly effective rate was 92.3%, the total effective rate was 100%. The monthly growth rate of height and weight of 92 RRI children treated with SQK acupoint injection was significantly higher than that of normal children (P <0.05). The first month of treatment of height and weight growth rate was significantly higher than the third and fourth courses of height and weight monthly growth rate, P <0.05. Conclusion BCG polysaccharide nucleic acid injection in the treatment of Zusanli can significantly improve the immune function of children with RRI, while also accelerating its growth rate of height and weight, improve the growth and development of backward conditions, no obvious adverse reactions.
