Objective To detect mycoplasma pneumoniae antibody in children having the upper respiratory tract infection.And then investigate mycoplasma pneumoniae infection status of different season different age children.Methods In 5 403 cases of suspected pneumonia mycoplasma infection of 0 to 14 years old children using the method of passive particle agglutination determination of mycoplasma pneumoniae antibody,and analysis of the statistical results.Results The positive rate was 67.8％ in the groups of children.The rates of infection was biggest during 2 to 3 years old children and 3-4 years old children,14.9％ and 18.4％,respectively.In addition,we found that the highest rate of mycoplasma pneumoniae infection arised from October to January every year of the following year.Conclusion The infection of mycoplasma pneumoniae is on the rise,and children aged 0 to 6 years old are the main population.

Objective To investigate the correlation between interleukin 10(IL‐10) ,tumor necrosis factor (TNF‐α) and serum CD4+ T‐lymphocytes cell in people who infected HIV .Methods The HIV antibody screening test ,IL‐10 and TNF‐αmeasurement adopted enzyme‐linked immune‐sorbent assay(ELISA) .The HIV antibody confirm test adopted western blot(WB) and CD4+ cell count determination used flow cytometry .Results Compared with the normal control group(NC group) ,the concentration of TNF‐αand IL‐10 in patients group have statistically significant difference(P<0 .05) .Moreover ,the extent of the increase in group A(pa‐tients with the CD4+ T cell count less than 3 .5 × 105 cells/mL) was higher than that in group B(patients with the CD4+ T cell count no less than 3 .5 × 105 cells/mL) .Conclusion Due to the defect of the immune system ,the serum concentration of TNF‐αand IL‐10 in people infected with HIV would increased ,and the increase of the concentration could be more significant in patients whose CD4+cell count obviously decrease .This study have shown that dynamic measurement of TNF‐α and IL‐10 concentration would provide data to konw the patients′immune status and illness development .

This article analyzed the laboratory indicators during the clinical diagnosis and treatment of two adolescents with mental disorders who developed rhabdomyolysis during hospitalization， so as to explore the risk of rhabdomyolysis occurring after mild to moderate exercise during treatment for adolescent with mental disorders and to provide references for clinical diagnosis and treatment.
