Abstract：ObjectiveTo explorethe predictive value of serum procalcitonin （PCT），peripheral blood complement C3， C4 and lymphocyte subsets CD3+， CD4+ and CD8+cells for plastic bronchitis （PB） in children with refractory Mycoplasma pneumoniae pneumonia （RMPP）.MethodsA totalof 22 children with RMPP were selected and divided into the PB group （51 cases）and the non-PB group（171cases）based on whetherthey werecomplicated with PB.Theserum PCTlevel of the childrenat admisionwas detectedbyfluorescence immunoquantitativeanalyzer，and levelsof complement C3andC4 were detected by immunoturbidimetry. The proportions of CD3+ CD4+ and CD8+T lymphocytes were detected by flow cytometry.

儿童难治性肺炎支原体肺炎（refractorymycoplasma pneumoniaepneumonia，RMPP）的特点是，尽管常规使用大环内酯类抗生素治疗超过7d，患儿仍高热不退或影像学呈进行性改变。（剩余11069字）
