Objective: To survey the mothers' acceptance of the HPV vaccination for their adolescent girls in Xiamen and to explore the influencing factors. Methods: Mothers of adolescent girls were selected by multistage cluster random sampling. Data of demography of the mothers and girls, the knowledge and attitude of cervical cancer and HPV vaccine of the mothers were collected. The influencing factors of mothers' attitudes were analyzed with univariate and multivariate logistic regression. Results: A total of 2 307 mothers were selected. The average age of mothers was (38.0±4.7) years. 13.1% (300) of the mothers had a family history of malignant tumor. The mothers' acceptance for vaccinating girls was 61.9% (1 428). The awareness rates of HPV and HPV vaccine were 42.5% (980) and 21.4% (493), respectively. Mothers who had family history of cancer (OR=1.36, 95%CI:1.02-1.82) showed a greater willingness to vaccinate their girls than the mothers who had not. Mothers who had knowledge of HPV (OR=1.32, 95%CI:1.08-1.62) and HPV (OR=2.03, 95%CI:1.56-2.66) vaccines showed a greater willingness to vaccinate their girls than the mothers who had not. Conclusion The mothers' acceptance to vaccinate adolescent girls against cervical cancer needs to be raised, especially for the mothers who had not family history of cancer, no-knowledge of HPV and HPV vaccines.

In this study, the psbA-trnH sequence as DNA barcode was used to evaluate the accuracy and stability for identification pteridophyte medicinal material Pyrrosiae Foliumas from adulterants. Genomic DNA from 106 samples were extracted successfully. The Kimura 2-Parameter (K2P) distances and ML tree were calculated using software MEGA 6.0. The intra-specific genetic distances of 3 original plants were lower than inter-specific genetic distances of adulterants. The ML tree indicated that Pyrrosiae Folium can be distinguished from its adulterants obviously. Therefore, the psbA-trnH sequence as a barcode of the pteridophyte, can accurately and stably distinguish Pyrrosiae Folium from its adulterants.

Objective To observe the incidence and explore the potential factors of nonresponse to cardiac resynchronization therapy (CRT) in patients with severe chronic congestive heart failure. Method CRT was performed in 119 patients with NYHA function class Ⅲ - Ⅳ and left ventricular ejection fraction ≤35% [96 men and 23 women, age (60.5 ± 11.3 ) years ]. Results Seven patients died for different reasons between 1 - 6 months post CRT and clinical and echocardiographic (Echo) data at 6 months post CRT were analyzed from the remaining 112 patients. The incidence of nonresponse to CRT was 28.57%.Compared to the response group, complete right bundle branch block, longer course of congestive heart failure, higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead( the great cardiac vein and the middle cardiac vein)were the independent predictors for nonresponse after CRT( all P ＜ 0.05). Compared with nonresponse group, the dosages of digoxin and diuretics used for heart failure were significantly reduced in response group ( P ＜ 0.01 ).Conclusions The incidence of nonresponse after CRT was 28.57% in this patient cohort Higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead ( the great cardiac vein and the middle cardiac vein) were the independent predictors for nonresponse after CRT.

OBJECTIVETo evaluate the clinical features of respiratory diseases of late preterm neonates.

METHODSSix hundred and thirty late preterm infant(gestational age: 34~36+6weeks),4401 cases of term infants and 328 early preterm infants who were born at the obstetrical department of Peking University 3rd Hospital from January 2009 to December 2010 were enrolled. Among them 84 late preterm infants, 135 term infants and 182 early preterm infants developed respiratory diseases. The incidence of respiratory diseases,clinical features and the severity of the diseases were compared among the three groups.

RESULTSThe incidence and mortality rates of respiratory diseases and the percentage of severe cases were significantly higher in the late preterm group than in the term group, but lower than in the early preterm group (P<0.01). The symptoms of respiratory disease occurred earlier in the late preterm group than in the term group, but later than in the early preterm group (P<0.01). The late preterm group had a significantly higher incidence of tachypnea and lower incidence of retraction sign when compared with the term and early preterm groups (P<0.05). The percentages requiring oxygen therapy and mechanical ventilation in the late preterm group were both significantly higher than in the term group, but lower than in the early preterm group (P<0.05). The multiple linear regression analysis showed 11 factors associated with the severity of respiratory diseases: decreased arterial partial pressure of oxygen, hematokrit, pH value and respiratory rate, arterial oxyhemoglobin saturation, systolic arterial pressure, 5 minute Apgar score and gestational age, and increased blood urea nitrogen, heart rate and respiratory rate.

CONCLUSIONSLate preterm infants are more likely to develop respiratory diseases than term infants, and to develop a more severe condition and need a more intensive respiratory support treatment. Tachypnea is a common presentation of dyspnea in late preterm infants and occurs earlier than in term infants but later than in early preterm infants. It may usually indicate a serious condition when dyspnea, abnormal heart rate and blood pressure, and multisystem damages occur in late preterm infants.

OBJECTIVETo study the changes in the migration of airway smooth muscle cells (ASMC) in asthmatic rats with airway remodeling and the effect of NK-1R inhibitor WIN62577 on the migration of ASMC.

METHODSSprague-Dawley rats were randomly assigned into two groups: airway remodeling induced by asthma and normal control. ASMC from rats with asthma and airway remodeling induced by ovalbumin (OVA) inhalation for 8 weeks were primary cultured and purified. Immunofluorescence and real-time PCR were used to measure the expression of NK-1R. With NK-1R inhibitor WIN62577 treatment, the changes in the migration of ASMC were measured by transwell chambers.

RESULTSNK-1R in ASMC was expressed mainly in the cytoplasm and cell membrane in the airway remodeling group, and the mRNA expression of NK-1R was higher than the normal control group (P<0.01). The number of the migrated ASMC in the airway remodeling group was significantly higher than that in the normal control group (P<0.01). Various concentrations (10-11 mol/L, 10-10 mol/L, 10-9 mol/L and 10-8 mol/L) of WIN62577 treatment decreased the number of the migrated ASMC (P<0.05).

CONCLUSIONSNK-1R may affect airway remodeling possibly through promoting the migration ability of ASMC in rats with asthma.

OBJECTIVETo evaluate the performance of computer-assisted imaging system in the detection of cervical squamous intraepithelial lesion and quality-assurance.

METHODSManual PAP screening (n = 140 580) and image-assisted screening (n = 32 885) were compared for the detection rates of squamous cell abnormalities, the atypical squamous cells (ASC) to squamous intraepithelial lesion (SIL) ratio, the positive rates of high risk human papillomavirus (HR-HPV) test in the case of atypical squamous cells of undetermined significance (ASC-US), and the correlation between cytopathology and histopathology.

RESULTSCompared with manual screening, computer-assisted imaging system showed increased overall positive detection by 0.32%, decreased detection of ASC by 0.21%, increased detection of low-grade squamous intraepithelial lesion (LSIL) by 0.22%, increased detection of high-grade squamous intraepithelial lesion or worse (HSIL) by 0.31%, and decreased ASC to SIL ratio from 2.59 to 1.60. Computer-assisted imaging system did not change the HR-HPV positive rate of the patients who were ASC-US, or the coincidence rate between cytopathology and histopathology. Moreover, the productivity of the laboratory operation increased 58.33%.

CONCLUSIONComputer-assisted imaging system significantly increases the overall positive detection rate of cervical SIL, improves accuracy and work efficiency of screening, decreases the ASC/SIL rate, and strengths the quality-assurance of laboratory testing.

OBJECTIVETo evaluate the efficacy and safety of percutaneous coronary intervention (PCI) combined cardiac resynchronization therapy (CRT) for refractory heart failure secondary to ischemic cardiomyopathy (ICM).

METHODSPCI and CRT were performed in 7 ICM patients confirmed by angiography with NYHA class IV, QRS duration >/= 130 ms in 6 of them, III degrees AVB in 1 patient, fast ventricular heart rate Af in 1 patient, ventricular fibrillation history in 2 patient. All of them had their LVEDD >/= 55 mm, and LVEF

RESULTSThe procedures of PCI and CRT were performed successfully in all patients. Five patients received right atrial and biventricular pacing, one patient with Af received biventricular pacing and atrial-ventricular node radiofrequency ablation at the same procedure, and the another one patient received CRTD. One out of seven patients died of re-AMI 4 months after the combination therapy, and the other 6 patients had been alive 5 - 41 (23.2 +/- 13.8) months during the follow-up period. The heart function of the 7 patients had further improved after PCI and CRT combined therapy compared to that of PCI or CRT only. Their NYHA class decreased from IV to II, 6-minute walking distance increased steadily, and mitral regurgitation reduced and QRS duration shortened significantly. The LVEDD decreased and LVEF increased significantly in 2 patients without ventricular aneurysm, and slight improvement or no change were in the other 5 patients.

CONCLUSIONFor patients with refractory heart failure secondary to ICM, the combination of PCI and CRT could obviously improve their heart function, quality of life and prognosis, which also very safe in perforation.

OBJECTIVETo evaluate the middle term effectiveness of medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar dislocation.

METHODSFrom February 2007 to January 2010, 65 patients including 6 males and 59 females with recurrent patellar dislocation received the MPFL reconstruction. The reconstruction was performed using ipsilateral semitendinosis tendon to restore the damaged MPFL. Patients were evaluated pre-operatively and post-operatively by physical and subjectively with the IKDC (International Knee Documentation Committee), Tegner, and Lysholm questionnaires and radiographic examination.

RESULTSThe average follow-up duration was 20 months (ranged, 15 to 23 months). No recurrent episodes of dislocation or subluxation occurred. A firm endpoint to lateral patellar translation was noted in all patients at most recent follow-up. The Lysholm subjective knee evaluation score improved from (60.6 +/- 3.7) preoperatively to (89.8 +/- 4.6) postoperatively; and Tegner scores improved from (3.6 +/- 0.4) to (5.6 +/- 0.3), IKDC from (40.0 +/- 3.5) to (82.0 +/- 3.6). Radiographic evaluation demonstrated improvements in the congruence and sulcus femoral angles.

CONCLUSIONMPFL reconstruction is an effective surgical procedure for the treatment of recurrent patellar dislocation.
