Abstract
BACKGROUND It is gradually accepted that solid bolus swallow needs to be added to the procedure of manometry. The motility differences in the upper esophageal sphincter (UES) and lower esophageal sphincter (LES) were not well described. Sierra Scientific Instruments solid-state high-resolution manometry (HRM) system, the most popular HRM system in China, lacks the Chinese normative values for both liquid and solid bolus swallow parameters. METHODS The esophageal HRM data of 88 healthy volunteers were analyzed. The parameters of both sphincters in resting stage were summarized and those during solid and liquid swallows were compared. KEY RESULTS Normative HRM values of sphincter parameters in solid and liquid bolus swallows in China were established. The UES residual pressure of solid bolus swallows was lower than that of liquid bolus (0.3±5.5 mm Hg vs 4.8±5.9 mm Hg, P=.000). The time parameters of UES relaxation between two types of bolus swallows were similar. In solid bolus swallows, the intrabolus pressure (IBP) (13.8±5.1 mm Hg vs 10.9±5.7 mm Hg, P=.000) and LES relaxation time (11.0±2.1 seconds vs 8.7±1.3 seconds, P=.000) were higher. The 4-second integrated relaxation pressure between both bolus swallows was similar. CONCLUSIONS & INFERENCES The function of the UES and LES between solid and liquid bolus swallows is different. Chinese HRM parameters are different from the Chicago Classification (http://www.chictr.org.cn, Number ChiCTR-EOC-15007147).

Abstract
Objective: To analyze the variations of PTPS gene in patients with suspected 6-pyruvoyl-tetra hydropterin synthase deficiency (PTPSD) and to make prenatal diagnosis in high-risk families. Methods: Chemiluminescence was used for phenylalanine detection in blood or dried blood spots.Patients with phenylalanine concentration over 120 μmol/L were detected by urine pterin analysis, and the activity of dihydropteridine reductase (DHPR) was detected. tetrahydrobiopterin loading tests were performed in suspected patients with abnormal urinary pterin profiles. PTPS gene variation analysis was performed by direct Sanger sequencing based on PCR amplification. Prenatal diagnosis in 7 high-risk families was performed by chorionic villus sampling when the genotype was identified. Results: In 656 patients with hyperphenylalanine, 22 cases were diagnosed as PTPSD clinically. 16 variations were detected in the 22 PTPSD cases. The 5 variations, p.Lys77Arg, p.Ile84Phe, c.315-2A>G, c.244-2A>T, c.187-1G>T, were identified as novel variations. Two fetuses carried the same mutation with the proband and therefore were thought to be PTPSD fetuses. Three fetuses carried only one mutant allele and thus were thought to be PTPSD carriers. The other 2 fetuses carried no mutations and were presumed normal. Conclusions: PTPS gene variation analysis is necessary to confirm the diagnosis. Prenatal diagnosis could help avoiding the defect birth in PTPSD families.

Abstract
Objective: To analyze the mutations of PAX3 gene in two Waardenburg syndrome type Ⅰ (WS1) pedigrees and make prenatal diagnosis for the high-risk 18-week-old fetus. Methods:PAX3 gene was first analyzed by Sanger sequencing and multiplex ligation-dependent probe amplification(MLPA) for detecting pathogenic mutation of the probands of the two pedigrees. The mutations were confirmed by MLPA and Sanger in parents and unrelated healthy individuals.Prenatal genetic diagnosis for the high-risk fetus was performed by amniotic fluid cell after genotyping. Results: A heterozygous PAX3 gene gross deletion (E7 deletion) was identified in all patients from WS1-01 family, and not found in 20 healthy individuals.Prenatal diagnosis in WS1-01 family indicated that the fetus was normal. Molecular studies identified a novel deletion mutation c. 1385_1386delCT within the PAX3 gene in all affected WS1-02 family members, but in none of the unaffected relatives and 200 healthy individuals. Conclusions:PAX3 gene mutation is etiological for two WS1 families. Sanger sequencing plus MLPA is effective and accurate for making gene diagnosis and prenatal diagnosis.

Abstract
Objective: To evaluate the potential efficacy and safety of gonadotropin-releasing hormone agonist(GnRH-a) administration in the luteal-phase on in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles in assisted reproductive technology (ART). Methods: The relevant papers published before November 2015 were electronically searched in PubMed, EMBASE, Cochrane Library, WHO ICTRP, ClinicalTrials.gov, CNKI, CBM and WanFang database to collect randomized controlled trial (RCT) involving GnRH-a administration in the luteal-phase on IVF/ICSI cycles in ART. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality according to the Cochrane Handbook. Then, Meta-analysis was performed using Stata 13.0. Results: A total of 3 406 patients, 3 280 IVF/ICSI cycles from 11 RCT were subjected to Meta-analysis. All cycles presented statistically significantly higher rates of live birth/ongoing pregnancy (RR=1.29, 95%CI: 1.11-1.51), clinical pregnancy (RR=1.24, 95%CI:1.08-1.43) and multiple pregnancy (RR=1.95, 95%CI:1.21-3.14) in patients who received luteal-phase GnRH-a administration compared with those who did not. Conclusions: These findings demonstrate that the luteal-phase GnRH-a administration could increase birth/ongoing pregnancy rate, clinical pregnancy rate and multiple pregnancy rate in all cycles, so it may be an ideal choice for luteal phase support in patients undergoing IVF/ICSI therapy.

Abstract
OBJECTIVE To investigate the incidence and risk factors of acute renal failure (ARF) after operation of frozen elephant trunk and total arch replacement for acute thoracic aortic aneurysm and dissection (TAAD) with mild hypothermic circulatory arrest (MHCA), and to analyze the long-term survival rate of the patients with ARF. PATIENTS AND METHODS From February 2009 to March 2015, patients with acute TAAD accepted operation of frozen elephant trunk and total arch replacement were enrolled. Those patients who were treated with renal replacement treatment (RRT) before the operation were excluded. The age, gender, cardiovascular disease history, preoperative serum creatinine and extracorporeal circulation duration in operation were recorded. On the basis of requiring RRT after TAAD operation, the patients were divided into ARF group and non-ARF group. The risk factors of ARF after TAAD operation were assessed by univariate and multivariate analysis. After completion of clinical follow-up, Kaplan-Meier curve was drawn to analyze five-year survival. RESULTS A total of 524 patients were included in the study. 51 cases of them got postoperative ARF. The incidence was 9.7%. The mortality rate of ARF group in the hospital was significantly higher than non-ARF group (25.5% vs. 3.6%; p<0.001). Univariate analysis showed that there was statistically significant difference in the age, gender, hypertension history, preoperative serum creatinine ≥200 µmol/L, extracorporeal circulation duration ≥260 min and combined with coronary artery bypass surgery simultaneously (p<0.05). Multiple logistic regression analysis showed that there were three independent risk factors of ARF after the operation, including hypertension (p=0.031, OR=2.377), preoperative serum creatinine ≥200 µmol/L (p=0.005, OR=4.451) and extracorporeal circulation duration ≥260 min (p=0.002, OR=3.295). The total five-year survival rate of ARF group after the operation was 56%. There was no statistically significant difference in the five-year survival rate between preoperative serum creatinine ≥200 µmol/L group and <200 µmol/L group (p>0.05). CONCLUSIONS The incidence of ARF after the operation was 9.7%. Preoperative serum creatinine ≥200 µmol/L, hypertension history and extracorporeal circulation duration ≥260 min were independent risk factors of ARF after the operation. The five-year survival rate of ARF after the operation was 56%. The preoperative serum creatinine level had no influence on the postoperative long-term survival.

Abstract
BACKGROUND In the present study, we aimed to describe, at the population level, patterns of adjuvant treatment use after curative-intent resection for pancreatic adenocarcinoma (pcc) and to identify independent predictors of adjuvant treatment use. METHODS In this observational cohort study, patients undergoing pcc resection in the province of Ontario (population 13 million) during 2005-2010 were identified using the provincial cancer registry and were linked to administrative databases that include all treatments received and outcomes experienced in the province. Patients were defined as having received chemotherapy (ctx), chemoradiation (crt), or observation (obs). Clinicopathologic factors associated with the use of ctx, crt, or obs were identified by chi-square test. Logistic regression analyses were used to identify independent predictors of adjuvant treatment versus obs, and ctx versus crt. RESULTS Of the 397 patients included, 75.3% received adjuvant treatment (27.2% crt, 48.1% ctx) and 24.7% received obs. Within a single-payer health care system with universal coverage of costs for ctx and crt, substantial variation by geographic region was observed. Although the likelihood of receiving adjuvant treatment increased from 2005 to 2010 (p = 0.002), multivariate analysis revealed widespread variation between the treating hospitals (p = 0.001), and even between high-volume hepatopancreatobiliary hospitals (p = 0.0006). Younger age, positive lymph nodes, and positive surgical resection margins predicted an increased likelihood of receiving adjuvant treatment. Among patients receiving adjuvant treatment, positive margins and a low comorbidity burden were associated with crt compared with ctx. CONCLUSIONS Interinstitutional medical practice variation contributes significantly to differential patterns in the rate of adjuvant treatment for pcc. Whether such variation is warranted or unwarranted requires further investigation.

Abstract
Objective: To assess the association between the concentration of the air pollutant PM2.5 and daily outpatient visits for respiratory disease. Methods: All records of daily outpatient visits to three hospitals in Shenzhen from January 1 to December 31, 2013 were collected. Daily air pollution monitoring and meteorology data from the same period were also collected in Shenzhen. The data were analyzed using a semiparametric generalized additive model with Poisson distribution of time series analysis controlling for long-term and seasonal trends, flu, DOW, public holidays, and meteorological factors. The excess risk(ER)of respiratory disease and its 95% CI value were calculated, along with the incremental increase of 10 μg/m3 in PM2.5 concentration. Results: Number of outpatient visits for respiratory diseases totaled 1 428 672(daily range: 1 790-5 228). The annual average PM2.5 concentration was 40.2 μg/m3(daily range: 7.2-137.1 μg/m3). The lag1 factor had the most significant impact on the lag effect. We estimated that a 10 μ g/m3 increase in day-before PM2.5 concentration was associated with a 1.809%(95% CI: 1.709%-1.909%)ER of visits for respiratory disease. After controlling for other pollutants(NO2, CO, and O3), the effect remained stable. When NO2, CO, and O3 were introduced separately, for every 10 μg/m3 rise in PM2.5 concentration, the excess risk of daily outpatient visits for respiratory disease was 1.814%(95% CI: 1.706%-1.923%), 2.780%(95% CI: 2.668%-2.892%), and 1.513%(95% CI: 1.403%-1.624%), respectively. With simultaneous control of NO2 and O3, NO2 and CO, and CO and O3, for every 10 μg/m3 rise in PM2.5 concentration, the excess risk of respiratory disease was 1.369%(95% CI: 1.242%-1.497%), 2.709%(95% CI: 2.590%-2.828%), and 2.577%(95% CI: 2.452%-2.702%), respectively. With simultaneous control of NO2, CO, and O3, for every 10 μg/m3 rise in PM2.5 concentration, the excess risk of respiratory disease was 2.370%(95% CI: 2.231%-2.509%). Conclusions: PM2.5 can increase the risk of outpatient visits for respiratory disease in Shenzhen.

Abstract
In order to investigate at the pore scale the mechanisms involved during CO2 injection in a water saturated pore network, a series of displacement experiments is reported using high pressure micromodels (geological labs on chip - GLoCs) working under real geological conditions (25 < T (°C) < 75 and 4.5 < p (MPa) < 8). The experiments were focused on the influence of three experimental parameters: (i) the p, T conditions, (ii) the injection flow rates and (iii) the pore network characteristics. By using on-chip optical characterization and imaging approaches, the CO2 saturation curves as a function of either time or the number of pore volume injected were determined. Three main mechanisms were observed during CO2 injection, namely, invasion, percolation and drying, which are discussed in this paper. Interestingly, besides conventional mechanisms, two counterintuitive situations were observed during the invasion and drying processes.

Abstract
Identifying genes of major effect for wool growth would offer strategies for improving the quality and increasing the yield of fine wool. In this study, we employed the Agilent Sheep Gene Expression Microarray and proteomic technology to investigate the gene expression patterns of body side skin (more wool growing) in Aohan fine wool sheep (a Chinese indigenous breed) in comparison with groin skin (no wool growing) at the anagen stage of the wool follicle. A microarray study revealed that 4772 probes were differentially expressed, including 2071 upregulated and 2701 downregulated probes, in the comparisons of body side skin vs. groin skin (S/G). The microarray results were verified by means of quantitative PCR. A total of 1099 probes were assigned to unique genes/transcripts. The number of distinct genes/transcripts (annotated) was 926, of which 352 were upregulated and 574 were downregulated. In S/G, 13 genes were upregulated by more than 10 fold, whereas 60 genes were downregulated by more than 10 fold. Further analysis revealed that the majority of the genes possibly related to the wool growth could be assigned to categories including regulation of cell division, intermediate filament, cytoskeletal part and growth factor activity. Several potential gene families may participate in hair growth regulation, including fibroblast growth factors, transforming growth factor-β, WNTs, insulin-like growth factor, vascular endothelial growth factors and so on. Proteomic analysis also revealed 196 differentially expressed protein points, of which 121 were identified as single protein points.

Abstract
BACKGROUND Lower cervical spine dislocation remains a surgical challenge. METHODS Twelve patients with lower cervical dislocation due to articular process injury underwent dorsal open reduction and manual pedicle screw rod fixation. Patients with cervical spinal cord injury received simultaneous open door expansive laminoplasty. Neurological function was evaluated using ASIA Impairment Scale 12. RESULTS Median time from injury to operation was 10 days (range, 5 to 52 days). Anatomic reduction was achieved in all patients. In nine patients with cervical spinal cord injury, 55.5% (5/9) showed improvement in ASIA grade following surgery. Unilateral numbness of the superior radicular area in one patient resolved 2 weeks post-surgery and two cases (11.1%, 2/9) had postoperative leakage of the cerebrospinal fluid, which resolved in 11 days and 13 days, respectively. CONCLUSION Dorsal open reduction and manual pedicle screw rod fixation is safe and effective for lower cervical spine dislocation due to articular process injury.

Abstract
OBJECTIVE To study the effects of condensate in the piezometric tube on patient ventilator interaction during noninvasive positive pressure ventilation. METHODS Eleven healthy adults volunteered to receive noninvasive positive pressure ventilation. Different capacity of physiological saline was injected gradually into the piezometric tube until the volunteers could not trigger the ventilator or the total volume of the water reached 1.5 ml. The dynamic changes of the pressure of mask(Pmask), piezometric tube near mask (Ppro), piezometric tube near breathing machine(Pdis), and the flow were observed. RESULTS With increasing volume of saline injected, the trigger time TItri(Pmask) increased from 0.09(0.07-0.11) to 0.31(0.22-0.39)s, the trigger pressure TPtri(Pmask) increased from 0.26(0.15-0.33) to 2.29(1.76-3.09)cmH2O, and the pressure-time product PTP (Pmask) increased from 0.02(0.01-0.03) to 0.55(0.41-0.68) cmH2O·s. Ineffective triggering rate increased from 0 up to 9 times/min, and spurious triggering rate increased from 0 up to 33 times/min. The plateau pressure of Pmask and Ppro exceeded the preset parameters, increased significantly as compared with 0 ml, from (9.74±0.34)to (15.79±3.10) cmH2O and from(9.80±0.31) to(15.44±3.47) cmH2O. The change of plateau pressure of Pdis was not significant [from (9.85±0.29)to (12.58±2.64)cmH2O]. The baseline pressure of Pmask, Ppro and Pdis changed from (3.67±0.36) to (8.40±3.22) cmH2O, from (3.71±0.32) to (8.13±3.55) cmH2O and from( 3.77±0.32) to (5.36±1.25) cmH2O, respectively. The pressure fluctuation of platform of Pmask increased significantly compare with 0 ml, from 0.60(0.48-0.71) to 7.94(7.11-8.63)cmH2O. The frequency of fluctuation of platform increased as many as 7 times during a single respiratory period. The time when the pressure of the Pdis began to change was delayed to Pmask and Ppro, 0.11(0.08-0.12)s compared with 0 ml. CONCLUSION Condensate in the piezometric tube during noninvasive positive pressure ventilation could influence patient-ventilator synchrony. To improve patient ventilator interaction in noninvasive positive pressure ventilation, condensate in the piezometric tube should be avoided.

Abstract
BACKGROUND AND AIMS This randomized controlled trial was conducted to examine whether prophylactic active drainage decreases morbidity associated with pancreati-coduodenectomy. MATERIAL AND METHODS A prospective, randomized controlled trial was conducted between April 2010 and May 2015 when 160 consecutive patients following elective pancreaticoduodenectomy were randomized intraoperatively to either prophylactic active drainage group or conventional passive drainage group. The main objectives were the incidence of postoperative pancreatic fistula and the associated clinical outcomes. RESULTS There were 82 patients in the active drain group and 78 patients in the passive drain group. The overall pancreatic fistula rate occurred similarly in the two groups (11.0% (9/82) vs 14.1% (11/78), p = 0.360). Grade C pancreatic fistula in active drain group was significantly less than that in passive drain group (0% (0/82) vs 6.4% (5/78), p = 0.026). The mean postoperative hospital stay and parenteral nutrition support time in active drainage group were shorter than those in passive drainage group (12.6 days vs 14.5 days, p = 0.037; 6.9 days vs 8.6 days, p = 0.047, respectively). CONCLUSION Prophylactic active drainage reveals significant reduction in severity of complications associated with pancreatic fistula and might be recommended as an alternative for patients with high risk of developing serious pancreatic fistula after pancreaticoduodenectomy.

Abstract
Knowledge of genetic diversity is important to assist breeders in the selection of parental materials and in the design of breeding programs. In this study, we genotyped 348 inbred tomato lines, representing vintage and contemporary fresh-market varieties, by using 52 single nucleotide polymorphisms (SNPs); 45 of these were found to be polymorphic. The average minor allele frequency and unbiased expected heterozygosity were 0.315 and 0.356, respectively. Population structure analysis revealed that contemporary germplasm could be distinctly divided into six subpopulations representing three market classes and breeding programs (pink, green, and red). Vintage germplasm could be separated into at least two subpopulations, and more admixtures were found in vintage lines than in contemporary lines. These findings indicate that contemporary inbred lines are more diversified than vintage inbred lines. AMOVA of vintage and contemporary lines was performed. A significant difference was found (P < 0.01), which explained 17.4% of the total genetic variance. Subsequently, we constructed a core collection using 45 polymorphic SNP markers. The data showed that all alleles were captured by only 2% of lines, indicating that more alleles, as well as rare alleles, could enable more variation to be captured in the core collection. These data allow us to discard redundant inbred tomato lines and to select elite inbred lines, which will accelerate the breeding process.

Abstract
Statins can increase endothelial function through enhancement of the expression and activity of endothelial nitric oxide synthase (eNOS). The aim of this study is to evaluate the effect of rosuvastatin on the number of circulating endothelial progenitor cells (EPCs) and endothelial expression of eNOS in monocrotaline-induced pulmonary hypertensive rats. Sixty Sprague-Dawley (SD) rats were divided into three groups of 20: control (group A), pulmonary hypertension (PAH) + rosuvastatin group (group B), and PAH (group C). Monocrotaline (MCT; 60 mg/kg) was injected (intraperitoneally) to induce PAH. Rats in group B received rosuvastatin [10 mg/(kg. day)] for 2 weeks. Peripheral blood (5 mL) was aspirated from the femoral artery of each rat before and after 2 weeks of treatment. Mononuclear cells were isolated and subcultured to obtain EPCs. Small and moderately sized pulmonary arteries were collected 2 weeks later for histological analyses. eNOS gene expression in endothelial cells of pulmonary arteries were then determined at mRNA and protein levels. eNOS expression at mRNA and protein levels and the number of circulating EPCs were reduced significantly in groups B and C compared with group A (P less than 0.05), and a significant difference between group B and group C (P less than 0.05) was observed. Vascular remodeling in small and moderately sized pulmonary arteries was attenuated markedly in group B compared with group C. These results suggest that rosuvastatin can ameliorate the remodeling of pulmonary arteries in MCT-induced PAH rats by increasing the number of circulating EPCs and eNOS upregulation.

Abstract
OBJECTIVE To investigate the treatment of surgical site infection(SSI) after spine surgery. METHODS Sixty-seven patients (aged 20-77 years with mean age of 51 years) with etiologically-confirmed surgical site infection after spine surgery in Peking University Third Hospital between July 2004 and December 2012 were retrospectively analyzed. There were 39 male and 28 female patients; 47 lumbar infections, 4 thoracic infections, 7 lower cervical infections and 8 upper cervical infections; 64 early infections and 3 delayed infections; 23 superficial infections and 44 deep infections; 47 monomicrobial infections and 20 polymicrobial infections. Ninety-six strains of bacteria were identified from the bacterial culture of 67 patients. Sixty strains were gram-positive pathogenic bacteria (62.5%), and the top three species were Staphylococcus aureus, S. epidermidis and Enterococcus faecalis. The remaining 36 strains were gram-negative pathogenic bacteria (37.5%), and the 3 species most predominant were Escherichia coli, Enterobacter cloacae, and Acinetobacter baumannii. All the patients with SSI were administered antibiotics. Debridement and irrigation-suction was performed if little symptomatic improvement was achieved in two-to-three days of antibiotics treatment, patients underwent 1-5 times of debridements (mean 1.5 times). RESULTS One patient was dead of MRSA septicemia, whom manifested as high fever, alalia and incision swelling when the infection occurred. The patient underwent polymicrobial of pulmonary infection and urinary tract infection during the period of hospitalization, and finally died of multiple organ failure. Sixty-six cases had wound healed, and they were followed up for 25-117 months (average 70 months), no recurrence of infection was found at last follow-up. Among the 65 cases of internal fixation, 56 cases reserved the implants, while implants were removed in other 9 cases for controlling infection. CONCLUSION Reasonable antibiotics and irrigation-suction are effective methods for managing surgical site infections after spine surgery and prevent removal of implants.

Abstract
To explore the association between rotavirus (RV) infection and histo-blood group antigens (HBGAs), a cross-sectional study was conducted in children hospitalized with diarrhoea in China from November 2014 to February 2015. In total, 424 sets of stool, saliva and buccal cell samples were collected. For the 125 RV-negative samples, 92% (104/125) were secretors/partial secretors, 8% (10/125) were non-secretors. Among the 299 RV-positive samples, 277 were P[8] and 22 were P[4]. All P[4] and P[8] positive individuals were secretors/partial secretors except for one P[8] (0.3%, 1/299), which was a non-secretor. These findings indicate that P[8] and P[4] RVs preferably infect secretors/partial secretors (p <0.001).

Abstract
Toxoplasma gondii is one of the most common protozoan parasites with widespread distribution globally. However, little information is available about the seroprevalence of T. gondii infection in geese (Anser domestica) in China. In the present study, the seroprevalence of T. gondii in geese were investigated in Hunan province, China. A total of 900 serum samples were collected from ten administrative regions in Hunan province, China, and assayed for T. gondii antibodies by Indirect Haemagglutination (IHA) test. Overall, 21.1% of the animals were positive for T. gondii antibodies. The results of the present survey indicated the presence of T. gondii infection in geese in Hunan province, China. Therefore, it is important to execute integrated control strategies and measures to prevent and control T. gondii infection in geese in this province. This is the first report seroprevalence of T. gondii in geese in Hunan province, China.

Abstract
The etiology and underlying biological mechanisms for preterm birth are relatively intricate, involving both genetic and environmental factors. Therefore, in the process of research on environmental factors of preterm birth, individual genetic susceptibility is an important aspect which cannot be ignored. Detoxification and metabolism abilities of enzymes to the environmental toxins is determined by their genetic polymorphism, which directly affect the toxic effects of poison. The measurement of gene polymorphisms related to metabolic enzymes may have important significance in the research of biological mechanisms, the risk prediction for preterm birth and the development of the preventive measures. In the recent studies, exposure to polycyclic aromatic hydrocarbons (PAH) seems to be an important risk factor for preterm birth. Cytochrome P450 (CYP450s) and glutathione S-transferases (GSTs) are the main metabolic enzymes of PAH and many other xenobiotics, and the polymorphisms of CYP1A1, CYP2E1, GSTM1, GSTT1 and GSTT2 may be associated with the risk of preterm birth. In this paper, we summarized that the research progress on the relationship between the gene polymorphisms of metabolic enzyme related to PAH and the risk of preterm birth.

Abstract
AIMS To investigate the toileting behaviours that female nurses used to empty their bladders, health beliefs related to toileting behaviour and the relationships between the health beliefs and toileting behaviour based on the Health Belief Model. METHODS A stratified cluster sampling strategy was used to recruit 636 female nurses from three tertiary hospitals in China. Reliable and valid questionnaires were used to assess female nurses' toileting behaviour and health beliefs related to toileting behaviour. The structural equation model was applied to explore the relationships between health belief constructs and toileting behaviour. RESULTS The most common unhealthy toileting behaviour was that of delayed voiding. More than half of the nurses (53.6%) often or always delayed emptying their bladders when they were busy. Approximately one-third of female nurses often or always crouched over the toilet to empty their bladders when not at home. Nearly two-thirds often or always worried about the cleanliness of public toilets. Of all the participants, 67.5% of female nurses had at least one type of lower urinary tract symptom (LUTS); however, the majority did not believe that they were susceptible to these symptoms. Moreover, they had misconceptions that premature voiding would reduce the risk, relieve the symptoms and prevent the recurrence of LUTS. CONCLUSIONS Many female nurses engaged in unhealthy toileting behaviours and might not know what types of toileting behaviours are healthy. Nurses play an important role in patient education and are a major source of health information for society. It is particularly important to look more closely at toileting behaviour among nurses and implement education and training to promote healthy toileting behaviour and, in turn, optimise bladder health.

Abstract
OBJECTIVE To study the risk factors of severe postoperative hypoxemia after surgery for Standford type A aortic dissection and establish a prediction model. METHODS Data of 411 consecutive patients from January 2014 to April 2015, who underwent surgery for Standford type A aortic dissection in the department of cardiovascular surgery of Beijing Anzhen Hospital, were retrospectively analyzed. All the cases were divided into two groups according to the appearance of severe postoperative hypoxemia. All the data about potential risk factors was put into the database and analyzed by logistic regression. The prediction model was then established upon acquired independent risk factors. Discrimination and calibration of the prediction model were assessed with ROC curve and Hosmer and Lemeshow goodness of fit test. RESULTS The perioperative in-hospital mortality was 6.57%(27/411). Severe postoperative hypoxemia (PaO2/FiO2≤100 mmHg) happened in 69 cases within 48 hours after procedures, with an incidence rate of 17.1%. The logistic regression demonstrated that body mass index (BMI), age, preoperative serum myoglobin, preoperative serum creatinine, preoperative serumalanine aminotransferase, the time of cardiopulmonary bypass, re-exploration within 48 hours after procedures were the independent risk factors for severe postoperative hypoxemia. The prediction model was then established based on these independent risk factors. The area under ROC curve of the model was 0.785, and the P value in Hosmer and Lemeshow goodness of fit test was 0.625. CONCLUSION The logsitic model built in this study succeeded to predict the incidence of severe postoperative hypoxemia after surgery for Standford type A aortic dissection, and it could meet the doctors' requirement with its excellent discrimination and calibration.

Abstract
The insulin-like factor 3 (INSL3 ) gene encodes 131 amino acids, consisting of two exons. In human beings, mutations of this gene may lead to bilateral cryptorchidism and infertility. However, the role of INSL3 in male spermatogenesis still remains controversial. We have analysed the coding sequence of INSL3 by PCR and DNA sequencing in 97 azoospermic patients with a history of bilateral cryptorchidism (patient group) versus 49 males with obstructive azoospermia (control group). The G178A mutation, which were predicted to alter the protein sequence (alanine to threonine), was detected in the patient group but not in the control group. While synonymous mutations G27A and G126A were detected in the control group, each occurred only in a single sample. When the patient group were divided into two subgroups according to the testicular biopsy result: sperm+ subgroup (51 cases with spermatozoa can be detected) or sperm- subgroup (46 cases with spermatozoa could not be detected). The INSL3 G178A polymorphism was not significantly associated with spermatozoa or no spermatozoa in the testes of males with a history of bilateral cryptorchidism. In conclusion, the evidence suggests that mutations of INSL3 may not directly contribute to the damage of spermatogenesis in patients with bilateral cryptorchidism history.

Abstract
Ochratoxins are a mycotoxin family frequently found in agricultural commodities worldwide and pose a potential health risk to humans and animals. To obtain large amounts of high-purity ochratoxins for food safety monitoring and toxicological research, a novel and effective method was established for simultaneous purification of ochratoxin A (OTA) and ochratoxin B (OTB) from a wheat culture inoculated with an ochratoxin-producing Aspergillus strain. The inoculated wheat culture was first extracted with methanol:water (80:20, v/v), followed by one or two cleanup procedures involving acid-assisted liquid-liquid extraction and gel permeation chromatography. Subsequently, target analytes were separated and collected using preparative high performance liquid chromatography. Finally, a combined approach of ultra-high performance liquid chromatography, ultraviolet spectrophotometry and mass spectrometry was applied for purity analysis and structural identification of the obtained toxins. As a result, 100 g of an inoculated wheat culture yielded 69 mg of OTA and 6 mg of OTB with purities greater than 98%. This proposed method might serve as a valuable reference to obtain expensive ochratoxin standards. To the best of our knowledge, this is the first report on simultaneous preparation of OTA and OTB from artificially inoculated wheat culture.

Abstract
We are developing a high brightness nano-aperture electron impact gas ion source, which can create ion beams from a miniature ionization chamber with relatively small virtual source sizes, typically around 100 nm. A prototype source of this kind was designed and successively micro-fabricated using integrated circuit technology. Experiments to measure source brightness were performed inside a field emission scanning electron microscope. The total output current was measured to be between 200 and 300 pA. The highest estimated reduced brightness was found to be comparable to the injecting focused electron beam reduced brightness. This translates into an ion reduced brightness that is significantly better than that of conventional radio frequency ion sources, currently used in single-ended MeV accelerators.

Abstract
INTRODUCTION With the introduction of iodized salt, more and more people are exposed to iodine sufficiency in some regions. The purpose of this study was to investigate the prevalence of nontoxic nodular goiter (NTNG) in the littoral region with high iodine supply after a nearly two- decade universal salt iodization. SUBJECTS AND METHODS Eight hundred and thirty- five participants (from 25~65 years; males 421 and females 414) were invited for the study from Huan-cui District of Weihai City, Shandong Province from January 2013 to September 2014. All participants were inspected and diagnosed by endocrinologists according to the thyroid function tests and the thyroid gland imaging. After the normal diet of three days, the urine samples of the participants were collected between 8:00AM and 9:00AM and the urinary iodine (UI) concentrations were analyzed using Urinary Iodide Test Kit. RESULTS The overall prevalence of NTNG in the region was 40.1%, and different prevalence occurred in the different age ranges (p<0.01). The prevalence of NTNG was 32.51%, 37.44%, 49.70%, 58.57 and 74.77% in the age group of ≤ 30, 31-40, 41-50, 51-60 and >60 years, respectively. Meanwhile, the prevalence of NTNG in women (42.08%) was higher than that in men (34.29%, p<0.05). The median of UI concentrations were 139.4μg/L and 101.5μg/L for the group with NTNG and without NTNG, respectively (p<0.01). However, there was no significant difference in UI concentrations among the groups with different age ranges (p>0.05), and statistical difference was not observed for UI concentrations between women and men (p>0.05). Intriguingly, higher UI concentrations were found in the group with larger thyroid size (p<0.01). CONCLUSION The iodine excess can lead to the high occurrence of nodular goiter in the littoral region, and individual UI concentration detection is recommended for the iodine nutritional status analysis among normal people when Universal Salt Iodization (USI) continues to be implemented in the region.

Abstract
OBJECTIVE Administrative data are used to describe the pancreatic cancer (pcc) population. The analysis examines demographic details, incidence, site, survival, and factors influencing mortality in a cohort of individuals diagnosed with pcc. METHODS Incident cases of pcc diagnosed in Ontario between 1 January 2004 and 31 December 2011 were extracted from the Ontario Cancer Registry. They were linked by encrypted health card number to several administrative databases to obtain demographic and mortality information. Descriptive, bivariate, and survival analyses were conducted. RESULTS During the period of interest, 9221 new cases of pcc (4548 in men, 4673 in women) were diagnosed, for an age-adjusted standardized annual incidence in the range of 8.6-9.5 per 100,000 population. Mean age at diagnosis was 70.3 ± 12.5 years (standard deviation). Five-year survival was 7.2% (12.8% for those <60 years of age and 3.6% for those >80 years of age). Survival varied by sex, older age, rural residence, lower income, site of involvement in the pancreas, and presence of comorbidity. CONCLUSIONS The mortality rate in pcc is exceptionally high. With an increasing incidence and a mortality positively associated with age, additional support will be needed for this highly fatal disease as demographics in Ontario continue to trend toward a higher proportion of older individuals.

Abstract
Globally, diarrhoeal diseases are the second leading cause of death among children under 5 years old. Few case-control studies on the aetiology of diarrhoea have been conducted in China. A case-control study on 922 children under 5 years old who presented with diarrhoea and individually matched controls was conducted in China between May 2011 and January 2013. Quantitative PCR was used to analyze stool samples for 10 diarrhoeal pathogens. Potential enteric pathogens were detected in 377 (81.8%) of 461 children with diarrhoea and 215 controls (46.6%, p <0.001). Rotavirus, norovirus GII, Shigella and adenovirus were qualitatively associated with diarrhoea. Using receiver operating characteristic curves, the optimal cutoff threshold for defining a symptomatic individual was 72, 5840, and 10(4) copies per reaction for rotavirus (odds ratio 259), norovirus GII (odds ratio 10.6) and Shigella (odds ratio 5.1). The attributable fractions were 0.18 for rotavirus, 0.08 for norovirus GII, 0.01 for Shigella and 0.04 for adenovirus. Coinfections between pathogens were common. Two pairs, rotavirus and adenovirus, and norovirus GII and Salmonella were positively associated. The co-occurrence of rotavirus and sapovirus, astrovirus, enterotoxigenic Escherichia coli or Campylobacter jejuni only occurred in children with disease. Coinfection was not correlated with clinical symptoms. Quantitative data are critical. Our results indicate that increased pathogen loads increase the OR between diarrhoea and rotavirus, norovirus GII and Shigella. Coinfections with rotavirus and norovirus GII are common and occur in a nonrandom distribution. Despite testing for ten diarrhoeal pathogens, over two-thirds of cases do not have a recognized attributable cause.

Abstract
Endothelial cells (ECs) apoptosis is an initial event in transplant arteriosclerosis (TA), resulting in allograft function loss. To elucidate the precise mechanisms of ECs apoptosis leading to neointimal smooth muscle cells (SMCs) accumulation during TA. We induced apoptosis in cultured ECs by overexpressing p53 through lentivirus-mediated transfection. ECs apoptosis induced the production of transforming growth factor (TGF)-β1 in both apoptotic and neighboring viable cells, leading to increased TGF-β1 in the culture media. Conditioned media from Ltv-p53-transfected ECs further promoted transition of cultured ECs to SM-like cells by activating TGF-β/Smad3, PI3K/Akt/mTOR, and MAPK/ERK signaling in a TGF-β-dependent manner. In transgenic rat aorta transplantation models, inhibition of ECs apoptosis in Bcl-xL(+/+) knock-in rat aortic allografts significantly reduced TGF-β1 production both in allograft endothelia and in blood plasma, which in turn decreased accumulation of SM22α+ cells from transgenic recipient ECs originally marked with EGFP knock-in in neointima and alleviated TA. Systemic treatment with SIS3, AP23573, or PD98059 also prevented recipient ECs-originated SM-like cells accumulation and intima hyperplasia in aortic allografts. These data suggest that allograft EC apoptosis induced recipient endothelial-mesenchymal (smooth muscle) transition via TGF-β signaling, resulting in recipient EC-derived SMC accumulation as a major mechanism of vascular remodeling during TA.

Abstract
The aim of this research was to identify the dynamic diversity of Small Tail Han sheep in its main producing areas between different years, and provide a basis for a breeding and genetic resources conservation strategy. For this purpose, 15 microsatellites were genotyped for Small Tail Han Sheep sampled in 2014 from Heze, China, and a comparative analysis of these data with those from a previous study was undertaken using meta-analysis. The results reveal that inbreeding has caused a reduction in diversity of Small Tail Han Sheep from 2008 to 2014. Overall, our results are helpful in understanding the dynamic change in diversity, as well as providing information for a conservation strategy for this population.

Abstract
MicroRNAs are very small endogenous RNA molecules that play a crucial role in an array of biological processes, including regulation of skin morphogenesis. The microRNA let-7b is thought to modulate animal hair growth, by binding target genes that encode growth factors. Fibroblast growth factor 5 (FGF5) has been previously reported to be involved in the initiation of the catagen phase of hair growth. In this study, we combined previous reports with bioinformatic analysis techniques to identify and validate FGF5 and, using lucerifase assay, confirmed targeted binding of let-7b to FGF5. To investigate the interaction between let-7b and FGF5, alpaca skin fibroblasts were transfected with let-7b over-expression vectors, and then mRNA and protein expression levels of FGF5 and the gene encoding its receptor, FGFR1, were evaluated. Levels of FGF5 mRNA and protein were remarkably lower in transfected groups, as compared to controls. In summary, this study confirmed that let-7b acts as a regulator of skin morphogenesis, by directly targeting FGF5 and down-regulating its expression. It provides the evidence of hair growth regulated by miRNAs in animals and may have important applications in wool production.

Abstract
OBJECTIVE In the clinical management of cirrhotic portal hypertension, surgery is often necessary; however, the operative mortality rate is high. PATIENTS AND METHODS Data from 161 patients, who underwent surgery for cirrhotic portal hypertension, were analyzed, and 24 potential predictors of surgical outcome were assessed. A Kruskal-Wallis rank sum test was used for single-factor comparisons, and multivariate logistic regression for multifactor comparisons to identify key factors for poor surgical outcomes and calculate their scores. RESULTS Six predictors of poor surgical outcomes were identified: postoperative bleeding within 30 h of > 2 L, with a score of 3; severe liver atrophy (an anteroposterior diameter of the left lobe of ≤ 55 mm and an oblique diameter of the right lobe ≤ 110 mm), with a score of 3; a base excess of <-3 mmol/L, with a score of 3; a platelet count of <3 T/L, with a score of 2; an amount of intraoperative bleeding of > 2 L, with a score of 2; and a red blood cell count of < 3 G/L, with a score of 1. For patients with good outcome (n = 147), all patients had a score of ≤ 3, except one patient who had a score of 4. With respect to patients who died (n = 14), all had a score of ≥ 5, except one patient who had a score of 4. A significant difference was observed between the two groups (p < 0.05). The mortality was 100% in patients with a score of ≥ 7. CONCLUSIONS Six key factors for poor surgical outcomes were identified in this study. Operative mortality appears to be significantly increased in patients with a score of 5-6. Surgery should be contraindicated in patients with a score of ≥ 7. To reduce mortality, close attention should be paid to preoperative and intraoperative treatment and prevention to achieve a score of < 4.

Abstract
The stability and exchange interaction mechanism of a doped Zn12O12 cluster with Mn and C atoms were investigated by first-principles calculations. For the Mn-doped Zn12O12 cluster, it is identified that a superexchange interaction deriving the hybridization between the Mn 3d(2/x)-2/y and O 2p(xy) orbitals dominates the Mn(↑)-Mn(↓) antiferromagnetic coupling, although a direct exchange interaction deriving the Mn-Mn bonding is also found. In order to turn the Mn spin state in the Mn-doped Zn12O12 cluster, C doping is undertaken to change the magnetic interactions of these impurities. It is proved that the C incorporation into the Mn-doped Zn12O12 cluster destroys the short-ranged antiferromagnetic coupling, where multiple exchange interactions take over, including the direct exchange interaction and the kinetic p-d exchange interaction partially due to the geometric distortion and surface effect with dangling bonds (sp(2)-like hybrids). It is concluded that the kinetic p-d exchange interaction plays a dominant role in Mn/C-doped Zn12O12 clusters.

Abstract
BACKGROUND Insulin protects cardiomyocytes from reactive oxygen species (ROS)-induced apoptosis after ischemic/reperfusion injury, but the mechanism is not clear. This study investigated the protective mechanism of insulin in preventing cardiomyocyte apoptosis from ROS injury. METHODS Rat cardiomyoblast H9c2 cells were treated with hydrogen peroxide (H2O2) or insulin at various concentrations for various periods of time, or with insulin and H2O2 for various periods of time. Cell viability was measured by the methylthiazolydiphenyl-tetrazolium bromide method. Cellular miR-210 levels were quantified using real-time RT-PCR. MiR-210 expression was also manipulated through lentivirus-mediated transfection. LY294002 was used to investigate involvement of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. RESULTS The percentage of viable cells was significantly and inversely associated with H2O2 concentration, an effect that was seemingly attenuated by insulin pretreatment. Treatments with H2O2 or insulin were associated with a significant increase in miR-210 levels. Manipulation of miR-210 expression by gene transfection showed that miR-210 could attenuate H2O2-induced cellular injury. Inhibition of the PI3K/Akt pathway by the Akt inhibitor LY294002 was associated with a decrease in miR-210 expression. CONCLUSION Insulin stimulated the expression of miR-210 through the PI3K/Akt pathway, resulting in a protective effect against cardiomyocyte injury that had been induced by H2O2/oxygen species. Our results provide novel evidence regarding the mechanism underlying the protective effect of insulin.

Abstract
We investigated the feasibility of interleukin-2 receptor gamma (IL2Rγ) gene based on gene mutation analysis and pre-natal diagnosis of X-linked severe combined immunodeficiency (X-SCID). Blood samples of patients and their parents of X-SCID (family 1) and X-SCID (family 2) were collected. IL2Rγ gene sequences of the 2 families were analyzed using bi-directional direct sequencing by polymerase chain reaction. DNA sequence changes in the IL2Rγ gene exon region and shear zone were also analyzed. We also sequenced the IL2Rγ gene in 100 healthy individuals. Prenatal genetic diagnoses for a high-risk fetus in family 1 were performed by chorionic villus sampling after determining each family's genotypes. The suspect fe-male in family 1 underwent carrier detection. Two novel mutations of IL2Rγ gene were identified, including c.361-363delGAG (p.E121del) in the patient and his mother in family 1, and c.510-511insGAACT (p.W173X) heterozygous mutation in the proband's mother in family 2. These mutations were absent in the 100 controls. Prenatal diagnosis of early pregnancy in the female fetus of family 1 was performed; the fetus was heterozygous, which was confirmed at postnatal follow-up. The suspect female in family 1 showed no mutation in carrier detection. The novel p.E121del and p.W173X mutations in IL2Rγ may have been the primary causes of disease in 2 families with X-SCID. In couples with an X-SCID reproductive history, prenatal gene mutation analysis of IL2Rγ can effectively prevent the birth of children with X-SCID and carrier detection for suspected females.

Abstract
The aim of this study was to investigate the clinical effect of western medicine therapy assisted by Ginkgo biloba tablets (GBT) in patients with vascular cognitive impairment with no dementia (VCIND). Eighty patients with VCIND were randomly divided into two groups: the conventional treatment group (control group) and the combined treatment group. The conventional treatment group was provided with anti-platelet aggregation conventional treatment. In this group, 75 mg aspirin was given three times a day for 3 months, whereas the combined treatment group was given 19.2 mg GBT three times a day for 3 months along with conventional anti-platelet aggregation treatment. Montreal cognitive assessment (MoCA) and transcranial Doppler ultrasonography were used to observe changes in cognitive ability and cerebral blood flow in patients with VCIND before and after treatment in the two groups. After 3 months of treatment, the MoCA scores of execution, attention, abstraction, delayed memory, and orientation were significantly increased in the combined treatment group compared with those before treatment and those in the control group after treatment. In addition, the blood flow velocity of the anterior cerebral artery was significantly increased in the combined treatment group. GBT can improve the therapeutic efficacy, cognitive ability, and cerebral blood flow supply of patients with VCIND.

Abstract
The aim of this study was to determine the effect of etomidate and propofol pretreatment on the expression of glucocorticoid receptor and the prognosis of sepsis. The sepsis rat was used as a model. During glucocorticoid treatment, etomidate and propofol were applied alone or together at different time points. Survival curves, glucocorticoid receptor expression in the rat adrenal cortex, and inflammation levels were determined. The outcome of sepsis in rats was evaluated based on the combined utilization of propofol and etomidate. The results indicated that the combined utilization of propofol and etomidate pretreatment could significantly improve the effects of glucocorticoids on rat sepsis. Etomidate was shown to enhance the expression of the glucocorticoid receptor, while propofol was shown to inhibit the inflammatory response. Etomidate was best used immediately after modeling, whereas propofol was most suitable for use during the peak inflammatory reaction. These results demonstrated that anesthetics had the ability to enhance the effect of glucocorticoids in the treatment of sepsis. Etomidate was indicated for use in the early stage of inflammation to enhance expression of the glucocorticoid receptor, while propofol application was indicated at the peak of the inflammatory reaction owing to its strong anti-inflammation effect.
