95%).Strains of PNSP were significantly more common than those PSSP(72.56% vs 22.72%),and strains of Sp resistant to erythromycin were significantly more common than susceptible to erythromycin too(94.42% vs 0.88%).Conclusions The antimicrobial resistance of Sp from children with lower respiratory tract infection in Wenzhou area has became a severe problem.Multi-drug resistance of Sp has been observed to chlorodeoxylincomycin,erythromycin,tetracycline and so on.The results will provide some important information for the therapy and the choice of antibiotics of Sp infection.

Objective To investigate the expression of Yes‐associated protein(YAP) in human papillary thyroid cancer and its influence on cell growth .Methods The samples in 57 cases of papillary thyroid cancer treated by operation resection in the gen‐eral surgery department of this hospital and the matched tumor‐adjacent tissues were collected .All the cases were definitely diag‐nosed by the pathology examination .The expression of YAP protein in the cancer tissue and corresponding tumor‐adjacent tissue were determined by the immunohistochemistry(IHC)staining .The relationship between the YAP protein and the clinicopathological data was statistically analyzed .siRNA was used to silence the expression of YAP in B‐CPAP cells ,MTT and flow cytometry were used to measure the proliferation and apoptosis changes .Results The expression level of YAP was markedly higher in papillary thyroid cancer tissues than in tumor adjacent tissues (P<0 .05);moreover the expression of YAP protein was positively correlated with the tumor size and TNM stage (P<0 .05) .Silencing YAP gene could significantly inhibit the cell proliferation ability and pro‐mote cell apoptosis(P<0 .05) .Conclusion YAP is highly expressed in papillary thyroid cancer tissues and is related with its ad‐verse clinicopathological characteristics ,down‐regulating YAP gene can significantly inhibit the cell growth .

Objective To investigate the relationship between the expression of CC chemokine ligand 5(CCL5)and S100 calcium binding protein A4 (S100A4)protein in breast cancer tissues with clinicopathological features and prognosis.Methods The expression of CCL5 and S100A4 in 40 cases of normal breast tissues and 120 cases of breast cancer were detected by immunohistochemistry,and the relationship between the degree of expres-sion and the clinicopathological features and prognosis of breast cancer was analyzed.Results The expression posi-tive rates of CCL5 and S100A4 in breast cancer tissues were 56.67% and 62.50% respectively,which were not expressed in normal breast tissues,and the differences were statistically significant (χ2CCL5 =39.403,P <0.01;χ2S100A4 =47.062,P <0.01).The expression of CCL5 in breast cancer tissues was statistically correlated with clinical staging(χ2 =10.141,P <0.01 ),pathological type (χ2 =5.769,P =0.017)and lymph node metastasis (χ2 =34.178,P <0.01),but not correlated with patients'age,tumor size,pathological grading(all P >0.05 ).And the expression of S100A4 was statistically correlated with clinical staging(χ2 =44.311,P <0.01)and lymph node metas-tasis(χ2 =14.843,P <0.01 ),but not correlated with patients'age,tumor size,pathological type and pathological grading(all P >0.05).The expression of CCL5 and S100A4 in breast cancer was positively correlated(r =0.301, P <0.01).CCL5 was positively correlated with the recurrence of breast cancer(OR =6.270,P <0.01),and S100A4 was not correlated with the recurrence of breast cancer(OR =1.103,P =0.768).Survival analysis showed that the disease -free survival time of patients with positive CCL5 expression was significantly shorter than the patients with negative CCL5 expression(χ2 =11.851,P <0.01 ),and the disease -free survival time of patients with positive S100A4 expression was significantly shorter than the patients with negative S100A4 expression(χ2 =5.433,P =0.021).The joint detection showed that the disease -free survival time in CCL5(+)+S100A4(+)group was sig-nificantly lower than that of CCL5(+)or S100A4(+)group(χ2 =15.341,P <0.01)and CCL5 (-)+S100A4 (-)group(χ2 =15.341,P <0.01).Conclusion The expression of CCL5 and S100A4 in breast cancer can reflect the metastasis and staging of breast cancer,which can be used to judge the clinical pathological characteristics and prognosis of breast cancer.

Objective To evaluate the performance of enzyme linked immunosorbent assay (ELISA) kit in detection of Hepatitis B virus(HBV) markers by using improved and optimized method ,so as to provide a practical and feasible method and reagents for clinical laboratory .Methods ELISA test was used for the detection of HBV markers .The gradient dilution method was used to e‐valuate the lower limit .The verifiation of cut off value was carried out based on clinical and laboratory standards institute (CLSI) EP12‐A2 document .Samples with cut off values were collected to evaluate the precision ,including repeatability and intermediate precision .The coincidence rates were counted through comparing the results of ELISA with those of external quality assessment and those detected by using Abbott i4000SR chemiluminescence instrument .Results The lower detection limit of HBsAg ,HBsAb , HBeAg ,HBeAb and HBcAb were 0 .2 IU/mL ,20 mIU/mL ,1 NCU/mL ,0 .75 NCU/mL and 0 .05 NCU/mL respectively .The cut‐off value(C50 )± 20% concentration included the concentration range between C5 and C95 .The within‐run coefficient of variation (CV)≤15% ,in sandwich method the between‐run CV≤25% ,in competition method the between‐run CV≤35% .The positive and negative coincidence rates in accuracy and comparing with i 4000SR all were more than 95% and all κ>0 .75 .Conclusion ELISA tests for HBV markers in our laboratory could meet the requirements of the detection performance and clinical needs .

Objective To investigate the change of cardiac function in elderly hypertensive patients with heart valve degenerative by echocardiography.Methods A total of 126 cases were divided into a valve disease group and non-valve disease group groups.The parameters of trial size,cardiac function and pulmonary artery pressure were detected.Results Of all 126 cases were the patients with hypertension including 28.6% (36/126) of valve disease group and 71.4% (90/126) of non-valve disease.There were 31 cases with mitral valve disease,22 cases with tricuspid valve disease; 26 cases with aortic valve disease; 36 cases with double or three alvular lesions in valve disease group.There was a significant difference in ventricle size and systolic function among valve disease group and non-valve disease group and control group.But there was no significant difference in thickness of ventricular wall between valve disease group and non-valve disease group.Conclusion The elderly hypertensive patient with valve disease was an independent factor for the development of congestive heart failure.
