Objective To investigate the prevalent feature of children with Mycoplasma pneumoniae (MP) infection in Xi'an region from Jan.2015 to Dec.2016.Methods From Jan.2015 to Dec.2016,9 648 cases with acute lower respiratory tract infection in xijing hospital were given serum test of the antibody of Mycoplasma pneumoniae by ELISA.Results A total of 9 648 cases with lower respiratory tract infection in children in xijing hospital received MP antibody detection,the positive cases were 2 971,the total positive rate was 30.79 ％.MP-IgM antibody positive rates between different age groups had significant differences,in which infants' group has the lowest(7.00 ％),and with the age growing,the positive rate increased.The positive rates in different age groups of toddler,preschool age,and school age were 27.29 ％,36.10 ％ and 37.76 ％ respec tively.The positive rates of MP-IgM antibody in different quarter were different.The highest antibody positive rate was found in the first quarter (January-March),followed by the fourth quarter,the third quarter and the second quarter.The difference was statistically significant (P＜0.01).Conclusion There was MP infection prevalence in Xi'an from 2015 to 2016.The positive rate in children increased with the age,the peak of infection was in the first quarter,so the detection and prevention of MP should be strengthened at that time of the year.

Objective To establish a mouse model of lymph node metastasis of breast cancer cells by luciferase imaging assay,to monitor early process of lymph node metastasis,and to evaluate the effect of X-ray radiation therapy on tumor.Methods The mouse mammary cancer cell line 4T1-Luc expressing luciferase was inoculated subcutaneously into the paw pad of nude mice to establish a model of subcutaneous lymph node metastasis.The lymph node metastasis in nude mice was continuously observed by in vivo fluorescence imaging system,and the nude mice with early lymph node metastasis of breast cancer cells were divided into control group and treatment group randomly.The radiotherapy effect was observed by in vivo fluorescence imaging system and evaluated by the pathological changes of HE staining of tumor tissue.Results A mouse lymph node metastasis model of breast cancer cells was successfully established,and the volume of primary tumor in paw correlated with the fluorescence photon number positively (r =0.958,P ＜ 0.001).On the twenty-fourth day after inoculation,the fluorescence photon number in pad tumor and popliteal fossa tumor of treatment group were significantly decreased in comparison with the control group (t =32.58,P ＜ 0.05),and the inhibition ratio of radiotherapy on tumor growth approached to 85 ％.HE staining showed that the apoptosis and necrosis in irradiated tumor was obviously higher than that in control group.Conclusions Bioluminescence imaging technique can be used to evaluate the effect of X-ray on breast cancer suppression and lymph node metastasis in mice.

Objective To analyze the expression of Yes-associated protein and risk factors in differentiated thyroid carcinoma. Methods Clinical data of 152 patients with differentiated thyroid carcinoma and 27 cases of benign thyroid tumor from Changji Hui Autonomous Prefecture People’s Hospital of Xinjiang, were analyzed retrospectively. According to the expression levels of Yes-associated protein in differentiated thyroid cancer and benign thyroid tumor, univariate Chi-square test and multivariate Logistic regression methods were used to analyze the relationship between Yes-associated protein and gender, age, thyroid stimulating hormone(TSH) level, nodule size, capsule integrity, histological type and lymph node metastasis, in order to find out risk factors in differentiated thyroid cancer. Results The positive rate of expressed Yes-associated protein in benign thyroid tumor group was 66.7%(18/27), which was significantly higher than 31.58%(48/152) of differentiated thyroid cancer group, and the difference was statistically significant(χ2=12.127, P<0.01). Under an optical microscope, changes of Yes-associated protein were found to be mainly located in the nucleus and cytoplasm , and in benign thyriod tumor the degree of staining was deep, strong positive or moderately positive; differentiated thyroid carcinoma was lightly stained or no staining, weakly positive or negative. Chi-square test showed that the expression of Yes-associated protein was not affected by sex, age and pathological type(χ2= 0.419, 0.221, 0.315, all P >0.05); TSH level, nodule size, capsule integrity, lymph node metastasis had an impact on the expression of Yes-associated protein which was down regulated (χ2=4.020, 8.424, 4.386, 6.673, P<0.05 or<0.01). Logistic regression analysis showed that the nodule size was not a risk factor ( odds ratio , OR ) of Yes-associated protein expression (OR=1.929, P>0.05); TSH levels above 4.5 mU/L, lymph node metastasis and envelope incomplete were risk factors that down regulated the expression of Yes-associated protein (OR=2.167, 2.665, 3.048, all P<0.05). Conclusion Yes-associated protein is down regulated in differentiated thyroid cancer. Elevated TSH levels , incomplete capsule and lymph node metastasis are risk factors of Yes-associated protein down expression and differentiated thyroid cancer.
