Objective To explore the pathogenic bacteria and immunologic mechanism of recurrent respiratory tract infection(RRI) in children.Methods The observation group included 50 children with RRI,26 cases were boys and 24 cases were girls, in Department of Respiratory Medicine of Wuhan Children′s Hospital were enrolled from Apr.2007 to Apr.2008.These children were divided into 3 subset groups:28 cases in 6 months-2 years old group,15 cases in 3-5 years old group,and 7 cases in 6-12 years old group.The healthy control group included 50 healthy children aged 6 months -12 years.The specimens were gathered on the next morning after the children entered hospital.The secretions of noses and pharynxes were gathered with clean and aseptic tampon from children with upper respiratory tract infection and placed in aseptic vessel,and were immediately detected with the pathogenic bacteria.The secretions of lower respiratory tract were gathered with suction method from children with lower respiratory tract infection and placed in aseptic vessel, and were immediately detected with the pathogenic bacteria,the number of superinfection with some kind of pathogenic bacteria was calculated.The children in observation group and healthy control group were exsanguinated of vein when the children were hungry to detect the cellular immunity(CD3+,CD4+,CD8+,CD4+/CD8+) and humoral immunity(IgA,IgM,IgG,C3,C4).Results Three hundred and two specimens in 6 months-2 years old group were detected,and 135 pathogenic bacteria were separated,the ratio of positive was 42.2%,and the number of superinfection was 25.One hundred and thirty-seven specimens in 3-5 years old group were detected,and 47 pathogenic bacteria were separated,the ratio of positive was 34.3%,and the number of superinfection was 7.Fifty-four specimens in 6-12 years old group were detected,and 16 pathogenic bacteria were separated,the ratio of positive was 29.6%,and the number of superinfection was 2.The top 5 kinds of bacteria that those children with RRI were easily infected were Ps.aeruginosa,K.pneumoniae,S.aurens,E.coli and streptococcus pneumoniae.The CD3+,CD8+ and CD4+/CD8+ of cellular immunity in the observation group were obviously lower than those in the healthy control group(Pa

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.
