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 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.

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.

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.

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.

OBJECTIVETo understand the HBV infection rate of peripheral blood mononuclear cells (PBMCs) from fetuses of HBsAg positive mothers, associated risk factors and to explore the clinical significance of detecting HBV infected PBMCs.

METHODSSixty eight pregnant women who were delivered at the First Hospital of Xi'an Jiaotong University, China from August 1995 to February 1997, and their newborns were studied. They were divided into two groups according to their status of HBV serological markers. The study group included 50 cases who were serum HBsAg positive and 18 cases without any HBV serum markers served as control group. All these cases had no symptoms of hepatitis, high risk premature labor, premature delivery and hypertensive disorder complicating pregnancy. Age and gestational age were matched in two groups. Blood samples (5 mL) were taken from the peripheral vein of pregnant women before delivery and from newborns within 24 h after birth, before inoculation of HBV vaccine (HBVac) and injection of hepatitis B immunoglobulin (HBIG). PBMCs were isolated. The sera and PBMCs were stored at -80 degrees C. HBV-DNA in serum and PBMCs were detected with nested polymerase chain reaction (n-PCR). Two pairs of oligonucleotide primers, the outer primer pair for first PCR and inner primer pair for second PCR, designed according to region S of HBV genome were synthesized by Shanghai Cell Biology Institute of Chinese Academy of Science.

RESULTSThe detection rate of HBV-DNA in serum and PBMCs from HBsAg positive pregnant women was 60.0% (30/50) and 40.0% (20/50), respectively. The detection rate of HBV-DNA in serum and PBMCs from newborns of HBsAg positive pregnant women was 46.0% (23/50) and 30.0% (15/50), respectively. Ten newborns were HBV-DNA positive in serum only, 2 were positive in PBMCs only and 13 were positive in both serum and PBMCs. In the control group, HBV-DNA was not detected in PBMC nor in serum. The positive rate of HBV-DNA in PBMCs of newborns was significantly higher in the group of mothers who were HBV-DNA or HBeAg positive in serum (P < 0.05, P < 0.01); the positive rate was significantly higher in the group of mothers who were HBV-DNA positive in both serum and PBMC than that in the group of mothers who were serum HBV-DNA positive only (P < 0.01); and it was markedly higher in the group of mothers who were PBMC HBV-DNA positive than that in group of mothers who were HBV-DNA negative in PBMCs (P < 0.01). The positive rate of HBV-DNA in PBMCs of newborns was significantly higher in the group of newborns who were HBV-DNA positive in serum than that in the group of newborns who were HBV-DNA negative in serum (P < 0.05).

CONCLUSIONSThe positive rate of HBV-DNA in PBMCs from newborns of HBsAg positive pregnant women was 30.0% (15/30). It was related to HBV viremia level and HBV-DNA status in PBMCs of mothers and newborns. Detection of HBV-DNA in PBMCs may be an important supplementary method to determine intrauterine HBV infection, and can predict the response to HBV vaccine.

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.
