Objective To investigate the expression levels and the roles of IL-17 and IL-23 in children with Mycoplasma pneumoniae (MP) pneumonia. Methods One hundred and three children with pneumonia admitted to pediatric department from February to May in 2012 were divided into MP pneumonia group and non-MP pneumonia group according to the results of MP antibody tests. Meanwhile, 42 healthy children were chosen as normal controls. Serum levels of IL-17, IL-23 and MP antibodies were measured in all children. Immunoglobulin, C reactive protein, total white blood cell count and granulocyte count were detected in children with pneumonia. Results The serum levels of IL-17 and IL-23 were signiifcantly different among three groups (P<0.05). The children in MP pneumonia group had higher levels of IL-17 and IL-23 than those in non-MP pneumonia group (P<0.05). Compared with the control group, levels of IL-17 and IL-23 were higher in two pneumonia groups (P<0.05). There was no signiifcant difference in levels of IL-17 and IL-23 between pneumonia patients with normal and with abnormal levels of immunoglobulin (P>0.05), while IL-17 and IL-23 levels were both positively correlated with granulocyte count (P<0.05).Conclusion IL-17 and IL-23 may be involved in the immune response of MP pneumonia and may contribute to the clearance of pathogens.

Objective To evaluate the clinical significance of bladder saline perfusion before catheter removal in TURP patients. Methods From 2009 to 2011,140 patients received TURP were enrolled in this study.Patients were divided into perfusion group (70 cases with bladder saline perfusion before catheter removal) and control group (70 cases without perfusion). Results Comparing with the control group (33.1 ± 5.4) min,the time waiting for urination was shorter in perfusion group ( 3.7 ± 0.2 ) min ( P <0.05 ).The recovering time to normal urination was shorter in perfusion group (7.7 ± 1.2 ) d than in control group (11.7 ± 1.3) d (P < 0.05 ) as well.In the first urine after catheter removal and first urine on the next day morning,white blood cell count of 2 groups (4.5 ± 0.1 ) vs ( 6.9 ± 3.5 ) ; ( 3.7 ± 0.2 ) vs (4.3 ±0.5) had significant differences ( P < 0.05 ). Conclusion Bladder saline perfusion before catheter removal in TURP patients is simple and effective for the restoration of normal voiding.

ObjectiveTo investigate the role of mitochondrial dysfunction in neurodegenerative diseases and the pharmacological effects of Shen-wu Capsule.MethodsSD rats were divided into 6 groups with 10 rats each:model group was developed by peritoneal injection of 3-nitropropionic acid(3-NPA) 20mg/kg, once every another day. Haloferidoli was used as the positive drug (given to positive control group from 10μg/100g/day to 100μg/100g/day, during modeling). Low dose of Shen-wu Capsule is 0.45g/kg; middle dose of Shen-wu Capsule is 0.9g/kg; high dose of Shen-wu Capsule is 1.8g/kg (once a day for 25days). The rats in normal control group were peritoneally injected with saline and were fed with water.The open field test was used to test the space recognition ability and excitability of CNS of rats. The climbing test was used to test strength of muscles.The content of dopamine(DA) and it's metabolite dihydroxyphenylacetic acid (DOPAC),5-HT in stratium of all groups were detected by high performance liquid chromatograph (HPLC-ECD).ResultsThe 3-NPA model rats showed decrease of activity, rigidity and stagger just like clinical patients with Huntington's diseases. In open field test all indexes of 3-NPA model rats are decreased (P<0.05), while Shen-wu Capsule low dose and high dose can improve all the indexes. There is no difference in strength of muscles among all groups. The content of DA,DOPAC and 5-hydroxytryptamine (5-HT) were distinctly decreased in 3-NPA model rats(P<0.01); rats in three groups of Shen-wu Capsule and positive drug control groups showed increased content of these neurotransmitter(P<0.01). Conclusions Rats injected with 3-NPA can mimic the abnormal behaviors and changes of neurotransmitter in stratium of Huntington's patients, Shen-wu Capsule can ameliorate the behavior of model animals and improve the content of DA,DOPAC and 5-HT in stratium.

Objective To investigate the relationship between the number of colonies and the luminous intensity of two kinds of platelets contamination bacteria,Escherichia coli(ECO)and Pseudomonas aeruginosa(PAE)in single platelets, plasma and phosphate buffered salines(PBS), and to explore their growth and proliferation in different biological fluid media.Methods The two luminescent bacteria were constructed before the correlations between the number of colonies and the luminous intensity in different media in vitro were observed with a small animal bioluminescence imaging instrument, and correlation analysis was carried out.By recording the luminous intensity at serial time points in different media, a growth curve was drown to reflect the proliferation of bacteria.Results There was a significant positive correlation between the number of colonies and luminous intensity of ECO and PAE in single platelets,plasma and PBS.The larger the number of colonies was,the stronger the luminous intensity was.The results indicated that single platelets significantly inhibited the proliferation of ECO and PAE,and that plasma also had some inhibitory effect,but not so strong.Conclusion For the two luminous bacteria,luminous intensity can represent the growth and proliferation of bacteria.Single platelets have obvious inhibitory effect on the growth of ECO and PAE, and the plasma also has some inhibitory effect, but the effect is not so strong as that of single platelets.
