Objective To explore the clinical characteristics and diagnosis of mycoplasma pneumoniae(MP) pneumonia showing lobar pneumonia.Methods Patients from Jan.2004 to Dec.2005 were selected as researching case,which had samptoms and signs of respiratory in clinic,the chest Xray shown lobar pneumonia,the MP of down respiratory′s secretion detected by polymerase chain reaction(PCR) and MP-IgM of serum detected by indirect hemagglutination were positive.The clinical data of them were reviewed.Results MP pneumonia showing lobar pneumonia was same to streptococcus pneumoniae pneumonia in clinic,but it had some characters:1.majority of the lobar MP pneumonia were children being student;2.the process was long,the samptoms of respiratory was tipical,the continuous fever was few,and the infectious samptoms was not obvious as streptococcus pneumoniae pneumonia;3.the injury to lung was more and tipical;4.the increase of white blood cell,neutrocyte and C-reactive protein were not clearly as to streptococcus pneumoniae pneumonia,but the absorbing of lung′s focal was relatively fast;5.the ?-lactams antibiotic was not effective,but macrolides was effective.Conclusions Clinical characters of MP pneumonia are needed to master,the variety of chest X-ray changes and differentiate from other pneumonia infected by other are needed to notice.

OBJECTIVETo evaluate the effects of Attractin (Atrn) silence on the anti-oxidative and anti-apoptotic abilities of TM4 Sertoli cells and its influence on the expressions of superoxide dismutase (SOD) and caspase6 in the cells.

METHODSWe observed the apoptotic indexes of TM4 Sertoli cells with normal expression (control), partial deletion, and complete deletion of the Atrn gene (psiRNA-TM4, psiAtrn-TM4, and mu-SC). We determined the mRNA and protein expressions of SOD and caspase6 by Q-PCR and Western blot, measured the SOD activity and malondialdehyde (MDA) contentby spectrophotometry, and detected the apoptotic index of the cells by TUNEL.

RESULTSCompared with psiRNA-TM4, after inhibition of the Atrn expression, the Sertoli cells in the psiAtrn-TM4 and mu-SCgroups showed significantly decreased expressions ofSOD mRNA (70.76% and 92.58%) and protein (65.11% and 71.0%) (both P < 0.05). The levels of caspase 6 mRNA and protein were increased 5.28 and 3.40 times in the psiAtrn-TM4 and 2.97 and 2.50 times in the mu-SCgroup as compared with the normal control (both P < 0.05). Atrn deletion markedly increased the apoptotic indexes of the cells in the psiAtrn-TM4 and mu-SC groups by 16.22% and 22.03% (P < 0.05) and reduced the activity of SOD by 23.00% and 39.37% (P < 0.05); it also elevated the level of MDA by 155.22% (P < 0.05).

CONCLUSIONThe Atrn gene exerts influence on the function of Sertoli cells in multiple ways, in which antioxidative stress and apoptosis regulation may play an important role.
