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.

BACKGROUNDThe treatment of high-grade developmental spondylolisthesis (HGDS) is still challenging and controversial. In this study, we investigated the efficacy of the posterior reduction and monosegmental fusion assisted by intraoperative three-dimensional (3D) navigation system in managing the HGDS.

METHODSThirteen consecutive HGDS patients were treated with posterior decompression, reduction and monosegmental fusion of L5/S1, assisted by intraoperative 3D navigation system. The clinical and radiographic outcomes were evaluated, with a minimum follow-up of 2 years. The differences between the pre- and post-operative measures were statistically analyzed using a two-tailed, paired t-test.

RESULTSAt most recent follow-up, 12 patients were pain-free. Only 1 patient had moderate pain. There were no permanent neurological complications or pseudarthrosis. The magnetic resonance imaging showed that there was no obvious disc degeneration in the adjacent segment. All radiographic parameters were improved. Mean slippage improved from 63.2% before surgery to 12.2% after surgery and 11.0% at latest follow-up. Lumbar lordosis changed from preoperative 34.9 ± 13.3° to postoperative 50.4 ± 9.9°, and 49.3 ± 7.8° at last follow-up. L5 incidence improved from 71.0 ± 11.3° to 54.0 ± 11.9° and did not change significantly at the last follow-up 53.1 ± 15.4°. While pelvic incidence remained unchanged, sacral slip significantly decreased from preoperative 32.7 ± 12.5° to postoperative 42.6 ± 9.8°and remained constant to the last follow-up 44.4 ± 6.9°. Pelvic tilt significantly decreased from 38.4 ± 12.5° to 30.9 ± 8.1° and remained unchanged at the last follow-up 28.1 ± 11.2°.

CONCLUSIONSPosterior reduction and monosegmental fusion of L5/S1 assisted by intraoperative 3D navigation are an effective technique for managing high-grade dysplastic spondylolisthesis. A complete reduction of local deformity and excellent correction of overall sagittal balance can be achieved.

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.

In order to evaluate the efficiency of ITS2 and psbA-trnH sequences used as DNA barcodes to distinguish Plantaginis Semen from its adulterants, we collected 71 samples of Plantaginis Semen and its adulterants. The ITS2 and psbA-trnH sequences were aligned through Clustal W, and the genetic distances were calculated by kimura 2-parameter (K2P) model and the Neighbor-Joining (NJ) phylogenetic trees were constructed using MEGA 5.1. The results indicated that the ITS2 sequence lengths of Plantago asiatica and P. depressa were 199 bp and 200 bp, respectively; the maximum intra-specific K2P distance were lower than the minimum inter-specific K2P distance; the NJ tree based on ITS2 sequence indicated that Plantaginis Semen and its adulterants could be distinguished clearly. The sequence lengths of psbA-trnH of both P. asiatica and P. depressa were 340 bp; the maximum intra-specific K2P distances were lower than the minimum inter-specific K2P distance; the NJ tree based on psbA-trnH sequence showed that Plantaginis Semen can be distinguished clearly from its adulterants except for P. major. Therefore, ITS2 sequences can be used as an ideal DNA barcode to distinguish Plantaginis Semen from its adulterants.

In order to develop potent antidiabetic agents that have inhibitory effect to a-glucosidase, twelve β-acetamido ketone derivatives such as N-{[(substituted-4-oxo-thiochroman-3-yl)phenyl]-methyl}acetamide are designed and synthesized through one-pot Dakin-West reaction. Their chemical structures are confirmed by 1H NMR, 13C NMR, IR and HR-MS. In vitro α-glucosidase inhibition assays of compounds 4a-41 were carried out using glucose oxidase method. The result indicated that most of them possess inhibitory activity in vitro. Compound 4k showed the most potent inhibitory activity with 87.3% inhibition of α-glucosidase at the concentration of 5.39 mmol x L(-1). The structure-activity relationship of these β-acetamido ketone derivatives was discussed preliminarily. Moreover, the molecular docking method was used to study the interaction mode of compound 4k and α-glucosidase. Our results will be helpful for designing of α-glucosidase inhibitors in the future.

OBJECTIVETo observe the quality of life in patients with post-traumatic epilepsy and discuss the influencing factors.

METHODSWe assessed 105 patients with post-traumatic epilepsy and 100 healthy people as control using Quality of Life Scale-31 (QOL-31), Self-rating Depressing Scale (SDS) and Self-rating Anxiety Scale (SAS), and conducted retrospective analysis on the depression, anxiety, site of trauma, control of seizure, EEG and therapeutic compliance.

RESULTSPatients with post-traumatic epilepsy scored much lower than the control group on QOL-31 (P less than 0.01), but higher than the control group on SDS and SAS (P less than 0.01). Multiple regression analysis indicated that major influencing factors on the quality of life were anxiety, therapeutic compliance, depression, poor control of epileptic seizure and site of trauma.

CONCLUSIONSThe quality of life in patients with post-traumatic epilepsy has significantly declined. Doctors should pay attention to psychological and mental problems of patients with epilepsy, such as depression and anxiety, enhancing therapeutic compliance and controlling epileptic seizure, which are the keys to improving prognosis.
