Objective To study the relationship between nitric oxide within cervical microenvironment and different HPV types as well as the effect of sodium nitroprusside( SNP), a nitric oxide donor, on the proliferation and apoptosis of cervical cancer cell lines. Methods HPV typing test was assessed from 115 women by using high-risk HPV (HR-HPV) 21 typing test and the release of cervical nitric oxide(NO) was assessed as nitrate, nitrite in cervical fluid. Cervical NO was then compared between women showing different HPV types. Proliferation of Caski and HeLa cervical cells was determined by methyl thiazolyl tetrazolium (MTT) assay, cell apoptosis was detected by flow cytometry after 24 hours treated by different final concentration of SNP (0. 125,0. 25,0. 5,1.0 and 2. 0 mmol/L, respectively). The expressions of HPV E6,E7 gene mRNA and p53 protein were detected by SYBR Green Ⅰ quantitative real-time PCR and western blot. Results ( 1 ) The cervical NO release of women with HR-HPV was higher compared to that in HPV negative women [ (47. 6 ± 1.4) μmol/L vs ( 22. 8 ± 0. 3 ) μmol/L; P ＜ 0. 05 ]; but there was no statistical difference between low-risk HPV (LR-HPV) group [ (24. 1 ± 1.2 ) μmol/L] and control group (P ＞0. 05 ). (2)After 24 hours treated by different final concentration of SNP, the results shown that SNP could inhibited the proliferation and increased apoptosis rate in Caski and HeLa cells, in which the concentration of SNP ≥ 1.0 mmol/L , there were significantly different ( P ＜ 0. 05 ), while when SNP ≥2. 0mmol/L, the proliferation of cells inhibited seriously. Treated by SNP ( 1.0 mmol/L ) 24 hours, the expressions of HPV18 E6, E7 mRNA in HeLa cells were reduced from 27. 362 ±0. 191,22. 962 ±0. 053 to19. 181 ±0. 360, 17. 571 ±0. 010 and the protein expression of p53 increased from 1. 17 ±0. 03 to 0. 23 ±0. 05, there were statistically significant differences between adding SNP group and the control group ( P ＜0. 05); but there were no statistically significant differences in HPV16 E6, E7 mRNA and that of p53 in Caski cells( P ＞ 0. 05 ). Conclusions The presence of HR-HPV is associated with an increased release of NO in the human uterine cervix; NO could inhibit the growth and proliferation and enhance the apoptosis of cervical cancer cells, inhibit the expression of HPV18 E6, E7 mRNA in HeLa cells and activate the expression of p53 protein, the mechanism may be due to higher sensitivity of HeLa cells (cervical adenocarcinoma cell) to SNP. The increasing release of NO may play a role in regulating the elimination of HPV in cervical microenvironment, which is a part of mucous membrane immunity.

Objective To observe the anti‐metastatic effect and mechanism of baicalin on the growth of HeLa cells was measured by MTT assay ,and cell migration baicalin on human cervical cancer HeLa cells .Methods The effects of baicalin on the proliferation and invasion of HeLa cells were analyzed by MTT method and Transwell assay .Moreover ,Real‐time PCR was used for investigating the expressions of MMP‐2 and MMP‐9 at the RNA level .Western blot was used for investigating the expressions of MMP‐2 ,MMP‐9 ,P38 and p‐P38 at the protein level .Results Baicalin could significantly inhibit the proliferation of HeLa cells in the dose‐dependent manner at the concentration above 60 μg/mL . Anti‐metastatic signaling induced by baicalin was characterized by down‐regulating the RNA and protein expressions of MMP‐2 and MMP‐9 ,and down‐regulating the phosphorylation level of P38 . Pre‐treatment of P38 signal pathway inhibitor could enhance the inhibitory effect of baicalin on the expressions of MMP‐2 and MMP‐9 .Conclusion These results indicate that baicalin‐induced anti‐metastatic effect involves the inhibition of MMP‐2 and MMP‐9 in HeLa cells through P38 signal pathway .

Objective To investigate the role of RNA-binding protein La protein in the invasion and migration of cervical cancer cells.Methods RNAi technology was used to silence the La protein in HeLa cell,a cell line of cervical cancer,and then screened by G418.Finally the stably expressed HeLa-shLa cell line was constructed and then wound healing,Transwell,Western blot and gelatin zymography assay were performed. Results After La protein HeLa was silenced by RNAi,the invasion and migration capabilities of HeLa cells were decreased significantly compared with those of the controls.Meanwhile,SiRNA-mediated depletion of La reduced the expression of MMP-2 and increased the expression of TIMP-2.Meanwhile the activity of MMP-2 was reduced too.Conclusion RNA-binding protein La promotes the invasion and migration of cervical cancer cells,which may be related to regulating its matrix metalloproteinases and inhibitors.

Objective To investigate the changes of pathogens distribution and antimicrobial resistance in children with urinary tract infection (UTI) in 10 years. Methods The results of urine culture and drug sensitivity in children with UTI from January 2001 to December 2003, and from January 2011 to December 2013 were retrospectively analyzed.Results In recent 10 years, there was no obvious change in the ratio of gram-negative bacteria to gram-positive bacteria. Escherichia coli was still the main bacteria causing UTI in children. The detection rate of enterococcus was signiifcantly increased from 18.3%in 2011-2013 to 7.5%in 2001-2003 (P<0.05) and it had become the second pathogenic bacteria. The isolation rate of ESBLs producing strains was signiifcantly higher in 2011-2013 than in 2001-2003 (P<0.05). The rate of Escherichia coli sensitive to imipenem re-mained at 100%and it is also sensitive to enzyme inhibitors antibiotics and nitrofuranto. Sensitivities to antibiotics were changed in different species of enterococcus. Conclusions The distribution of pathogens and antimicrobial resistance in children with UTI are constantly changing. The clinician should pay close attention to changes of epidemiology in the region and hospital and rational use of antimicrobial drugs.

Objective To evaluate the right ventricular global systolic function by real-time three dimensional echocardiography (RT-3DE) and two dimensional echocardiography (2DE) in normal children,and investigate their correlation with age,height,weight,body surface area (BSA) and cardiac cycle time.Methods In 192 normal children,2DE right ventricular systolic function indexes were obtained at the apical four chamber view,including:tricuspid annular lateral wall peak systolic excursion (TAPSE),tricuspid annular peak systolic velocity (TRV) and right ventricular systolic area shortening (RVa).Full volume imaging of right ventricle was obtained at the parasternal four-chamber view near the apex by RT-3DE.The right ventricular ejection fraction (RVEF) was analyzed by TomTec RV-Function.The correlation analysis was performed between RT-3DE and 2DE indexes.The correlation and regression analysis on RT-3DE and 2DE indexes with above physical development indexes were also studied.At the same time 192 normal children were divided into five groups by age.2DE and RT-3DE indexes were compared with each other among five age groups.Results RVEF had no statistical correlation with all 2DE indexes (P ＞0.05).The correlation analysis on RT-3DE and 2DE indexes with physical development indexes demonstrated that TAPSE,TRV had strong positive correlation with the above indexes (P =0.000),while RVa had no statistical correlation with the above indexes (P ＞0.05).RVEF had weak positive correlation with cardiac cycle time r =0.180,P =0.014),but it had no statistical correlation with the other indexes (P ＞0.05).Stepwise regression analysis showed that the significant factor for TAPSE and TRV was height (R2 =0.508,P =0.000)and BSA (R2 =0.130,P =0.000)separately.In five age groups RVEF and RVa remained constant (P ＞0.05).However for TAPSE and TRV significant difference were found in part of comparisons between groups(P ＜0.05).Conclusions Although RVEF assessed by RT-3DE was slightly influenced by heart rate,it was independent of age,height,weight,BSA.It was a stable index for evaluating right ventricular systolic function among different age and physical development population.

Objective To evaluate right ventricular(RV) global and regional volume and systolic function by real-time three-dimensional echocardiography (RT-3DE) in normal children with different age.Methods One hundred and ninty-two normal children were divided into five groups by age:group Ⅰ,＜1 years old,32 cases;group Ⅱ,≥1 years old-＜3 years old,46 cases;group Ⅲ,≥3 years old-＜6 years old,36 cases;group Ⅳ,≥6 years old-＜9 years old,41 cases;group Ⅴ,≥9 years old-＜14 years old,37 cases.Full volume imaging of RV was obtained at the parasternal four-chamber view near the apex by RT-3DE.RT-3DE data set were analyzed off-line by TomTec RV-Function.RV were divided into three parts:inflow,body,outflow.The measurements were including RV global and regional end-diastolic volume (EDV),end-systolic volume (ESV),ejection fraction (EF) and the ratio of regional parts EDV to RVEDV. The volume and systolic function were compared in three regional parts.RV global and regional parts EF and the ratio of regional parts EDV to RVEDV were also compared in five age groups.Correlation analysis and curve estimation were studied on RV global and regional EDV with age and physical development indexes.Results In the comparison of three regional parts:inflow EDV and EF were higher than outflow and body parts (P＜0.05).No significant different was found between outflow EDV and body EDV (P＞0.05),however,outflow EF was significant higher than body EF(P＜0.05).The comparison of RV global and regional EF in five age groups were no statistical different (P＞0.12). The ratio of regional parts EDV to RVEDV remained constant in five age groups(P＞0.58).Correlation analysis showed the global and regional RV volume were strongly correlated with age,height,weight and BSA (r＞0.77,P=0.000).The best correlation was found with BSA (r＞0.83,P=0.000).Curve estimation demonstrated that the relationship of RV global and regional EDV with age and physical development indexes could be best expressed by power model,the best matched model were found with BSA.Conclusions Among three regional parts of RV,inflow and outflow parts volume contraction were the two main contribution factors for RV function.In childhood RV volume didn't increase linearly with age and physical development indexes,but in an exponential model.
