Objective To identify the clinical risk factors of refractory Mycoplasma pneumoniae pneumonia (RMPP) and their values in early diagnosis. Methods The retrospective analysis of clinical data was conducted in 142 children with Myco-plasma pneumoniae pneumonia (MPP) admitted to Changhai Hospital of Second Military Medical University from Jan. 2012 to Jan. 2014. All children were divided into two groups, RMPP group (n=112) and MPP group (n=30). The comparison was made between two groups in clinical data. The factors were analyzed by the multifactor logistic regression. Results As compared to MPP, RMPP had longer fever duration, the higher ratios of large consolidation shadows, extrapulmonary complications and in-creased CRP level (P<0.05). The results of logistic regression indicated that the clinical risk factors included large consolidation shadows (OR=6.57, 95%CI:2.10-20.56), extrapulmonary complications (OR=11.66, 95%CI:2.42-56.08) and CRP (OR=14.87, 95%CI:2.67-82.79) (P<0.01). Conclusions Large consolidation shadows, extrapulmonary complications and CRP are clinical risk factors of RMPP. CRP elevation and lung imaging changes are valuable in early diagnosis of RMPP.

Objective: To study the infectious state of 3 kinds of viruses (CVB, CMV and EBV) in respiratory tract infection and its significance. Methods: Among 290 patients studied, there were 158 boys and 132 girls, aged from 6 months to 12 years. The antigen of coxsackievirus B (CVB-Ag) and antibody of coxsackievirus B (CVB-IgM), antibody of cytomegalovirus (CMV-IgM) and antibody of EB virus (EBV- IgM) were detected by ELISA method. Results: (1) The positive incidence of upper respiratory tract infection, bronchitis, pneumonia was higher than that of noninfectious disease group (P<0.01). The positive incidence of CVB was higher than that of CMV and EBV(P＜0.01). (2)There were cross viruses positive, especially in pneumonia group (P<0.05), usually CVB cross other virus infection. (3) The course of pneumonia was long in single CVB (P<0.01) and longer in cross infection of viruses (P<0.01). Conclusion: CVB infection is the most common one in the 3 viruses. Attention should be paid to multiple viruses infections in pneumonia children.

Objective To study the clinical manifestation,diagnosis,differential diagnosis and the essentials of management and treatment of fibrodysplasia ossificans progressiva (FOP).Methods Three cases of FOP were reported.The features of clinical manifestation and radiography were studied.The literature related to FOP was reviewed.Results FOP affected young children′s age of onset was between 10 days and 2 years (mean age 1 3 years).Mean disease duration was 5 3 years (range 2～11 years),and mean age 5 3 years (range 2～11 years) with sex ratio 1∶2 (boy∶girl).Soft tissue swelling in cervical and dorsal regions with or without local pain and warmth,and low fever were the early clinical manifestations.These nodules usually disappeared spontaneously,but some of nodules gradually developed ossification.The X ray features included ectopiac ossification most frequently in the soft tissue of the upper back and neck,next,the loin,chest and extremities.Two cases showed short hallux and hallux valgus.Exacerbation of the two cases was precipitated after muscle biopsy and careless venepuncture.All patients showed progressive extra articular bony ankylosis of most joints of axial and/or appendicular skeleton with severe movement restriction.Conclusion FOP is a rare and disabling genetic disorder of connective tissue.FOP should be diagnosed as early as possible and non invasively,based upon history,clinical and radiological findings.The finding of abnormalities of the great toe is helpful to diagnose FOP so that management can be early and adequate.Manogement principle includes avoiding conditions potentially provocative of abnormal ossification.The disease should be familiar to pediatricians.

Objective: To understand the relationship between coxsackievirus B and pediatric diseases. Methods: The infectious state of coxsackievirus B in hospitalized children were studied. Among 796 children studied, there were 218 upper respiratory tract infection cases, 179 pneumonia, 106 asthma, 155 myocarditis, 19 allergic purpura and 89 other diseases. The antigen (CVB-Ag) and IgM (CVB-IgM) were detected using ELISA method. Results: (1)There were 47% positive of CVB in upper respiratory tract infection and 48% positive of CVB in pneumonia(no difference between them, P>0.05). (2) There were 62% positive of CVB in asthma, 61% positive of CVB in myocarditis and 68% positive of CVB in allergic purpura(no difference among them, P>0.05)； But the positive rate of CVB in asthma, myocarditis and purpura were higher than in upper respiratory tract infection and pneumonia, (P<0.05). (3) There were lower positive rate of CVB in other kinds of diseases (16%) and in healthy children (3%)(no difference between them, P>0.05). Conclusion: CVB infection was related to several kinds of diseases, the relationship between CVB infection and diseases such as asthma, myocarditis, and allergic purpura should be further studied.

Background and purpose:Integrinαvβ3 receptor plays an important role in promoting, sustaining and regulating the angiogenesis. It is overexpressed on neovascular endothelial cells and tumor cells. RGD peptide specifically binds to integrinαvβ3, which could evaluate growth status and invasiveness of tumor. This study aimed to investigate the biodistribution in healthy KM mice and micro PET/CT imaging in U87MG tumor-bearing mice of 18F-E[c(RGDfK)2]. Methods: 18F-E[c(RGDfK)2] was produced using an automated synthesis module via a simple one-step 18F-labeling strategy of the precursor 4-NO2-3-TFMBz-E[c(RGDfK)2]. The percentage activity of injection dose per gram of tissue (%ID/g) was calculated at 0.5, 1, 2, 4 h post injection of the probe. Micro PET/CT images of U87MG tumor-bearing nude mice with or without 18F-E[c(RGDfK)2] blocking were acquired at each time point. Results: The labeling efficiency and radiochemical purity of 18F-E[c(RGDfK)2] were 10% and 98%, respectively. 18F-E[c(RGDfK)2] was excreted via renal route, with a high blood clearance. The other organs had background-level activity accumulation. At 1 h, the%ID/g of kidney, liver, intestine, muscle and blood was (1.02±0.16)%ID/g,(0.24±0.06)%ID/g, (0.35±0.03)%ID/g, (0.13±0.03)%ID/g and (0.11±0.03)%ID/g 18F-E[c(RGDfK)2] had initial high tumor uptake [(5.2±0.56)%ID/g] and good tumor-to-background contrast (5.36) at 1 h post injection. Tumor uptake for blocking group was lower than those without blocking, and T/M reduced to 1.57. Conclusion: 18F-E[c(RGDfK)2] appears a promising PET molecular imaging probe targeting integrin αvβ3, with high tumor uptake. It could be suitable for prognosis evaluation of integrin-positive tumor, selection of vascular targeting therapy and therapy effect monitoring.
