Objective To investigate relationship between infection rate of Mycoplasma pneumoniae(MP) in children with corresponding gender, age and season. Methods Mycoplasma pneumoniae IgM (MP-IgM) antibody level in serum was measured utilizing method of passive particle agglutination. Results From 2007 to 2009, MP-IgM antibodies among total 1701 children with pneumoniae were detected in the study, of which 569 cases showed MP-IgM antibodies positive (569/1701,33.5%). The MP-IgM positive rate in male and female patients were 30.1% and 37. 8% respectively and the difference was statistically significant (P ＜ 0. 01). The MP-IgM positive rates in 0 ～ 1year-old group,2 ～ 3 year-old group ,4 ～ 6 year-old group and 7 ～ 14 year-old group were 5.8% ,35.3% ,43.3% and 52.9%, respectively. The disparities of MP-IgM positive rate between the groups was statistically significant (P ＜0.01,P ＜ 0.01 and P ＜ 0.05, respectively). The differences of MP-IgM positive rates during the peroid of 2007,2008and 2009 were statistically significant(P ＜ 0.01), but no difference was significantly exhibited during the peroid of 2008 verse 2009 (P ＞ 0.05). As for onset distribution of season, in year 2007, MP infection rates between the individual seasons were not statistically different. Conclusion MP infection was mainly prevailed in those whose ages were over three years old. MP infection was inclined to occur in female children than in male and the prevalent season was the Spring.

: ObjectiveTo study the effect of acupuncture on resistin and adiponectin and its gene expression in type 2 diabetic rats.MethodsThe rats of type 2 diabetes model were randomly divided into acupuncture group, rosiglitazone group and model control group, meanwhile 8 normal rats were assigned as the normal control group. The changes of total cholesterol(TC), triglycerides(TG), high density lipoprotein-cholesterol(HDL-C) and fasting plasma glucose (FPG) were measured. The expression of resistin gene and adiponectin gene in the adipose tissue was determined with RT-PCR. The level of serum resistin and adiponectin in type 2 diabetes rats were observed before and after acupuncture.ResultsThe levels of TC, TG, FPG resistin lowered obviously, and the levels of HDL-C adiponectin raised significantly. The expression of resistin gene lowered obviously. The expression of adiponectin gene significantly raised in acupuncture group, compared with the model control(P＜0.01, P＜0.05).ConclusionAcupuncture can decrease resistin gene expression, raise adiponectin gene expression, accordingly release insulin resistance.

Objective To investigate the effects of ischemic preconditioning on pneumocyte apoptosis and the expression of HSFT0 after lung isehemia-reperfusion(I/R) in rats and discuss its possible mechanism of extenu-ating ischemia-repedusion injury. Method Thirtysix male Sprague-Dawley rats were randomly divided into three groups [ sham operation(SO ) group, ischemia-teperfusion(L/R) group, and ischemic preconditioning(IP) group],twelve in each group. Lung croas-clamping was used to build the L/R model. In IP group, three cycles of 5-minute-ischemia + 5-minute-reperfusion were given to the pulmonary artery before the procedure. Sham operation rats had a thoracotomy only. Two hours(or five hours) reperfusion was given to both L/R and IP group. Tenninal-deoxynucleotidyl Transferase Mediated d-UTP Nick End Labeiing(TUNEL) was used to evaluate apoptosis. Expression of HSP/0 in lung was observed by immunohistochemical stain and image analysis. Index of quantitative assessment of histologic lung injury(IQA), wet to dry weight ratio(W/D) were measured. The pathological change of lung tissue was observed under both hght and electron microscopy. Statistical analysis was carried out by One-way Anova. Scheffe test was used for intragroup comparison. Results The apoptosis index and expression of HSP70、W/D,IQA of hng tissue in I/R group were higher than those in the sham operation group (P<0.01). Compared with the L/R group, the apoptosis index and expression of HSP70, W/D, IQA of lung tissue significantly decreased (P<0.01), the levels of expression of HSPTO increased significantly in IP group ( P<0.01 ). The pathological and ultrastructure change of lung tissue was better in IP group than those in I/R group. Condusions Ischemic preconditioning can extenuate lung I/R injury by the possible mechanism of increasing the expression of HSPT0 which inhibits the apoptosis during lung I/R injury.
