Abstract
Two prominent polybrominated diphenyl ether (PBDE) congeners have been included in the persistent organic pollutant list, 2,2',4,4',5-tetrabromodiphenyl ether (BDE-99) and 2,2,4,4'-tetrabromodiphenyl ether (BDE-47), which have been detected in treated municipal wastewater, river water, and sediments in China. A lab-scale column experiment was established to investigate the effects of the competitive sorption of BDE-47 on BDE-99 biodegradation and migration in two types of river-based aquifer soils during groundwater recharge with reclaimed water. Two types of recharge columns were used, filled with either silty clay (SC) or black carbon-amended silty clay (BCA). The decay rate constants of BDE-99 in the BCA and SC systems were 0.186 and 0.13 m-1 in the single-solute system and 0.128 and 0.071 m-1 in the binary-solute system, respectively, showing that the decay of BDE-99 was inhibited by the coexistence of BDE-47. This was particularly evident in the SC system because the higher hydrophobicity of BDE-99 determined the higher affinity and competition for sorption sites onto black carbon. The biodegradation of BDE-99 was suppressed by the coexistence of BDE-47, especially in the SC system. Lesser-brominated congeners (BDE-47 and BDE-28) and higher-brominated congeners (BDE-100, BDE-153, BDE-154, and BDE-183) were generated in the four recharge systems, albeit at different ratios. Bacterial biodiversity was influenced by the presence of BDE-47 in the SC system, while it had no significant effect on the BCA system, because the high sorption capacity of black carbon on the hydrophobic PBDEs effectively reduced their toxicity. The ranking order of the most abundant classes changed markedly due to the coexistence of BDE-47 in both the SC and BCA systems. The ranking order of the most abundant genera changed from Azospira, Methylotenera, Desulfovibrio, Methylibium, and Bradyrhizobium to Halomonas, Hyphomicrobium, Pseudomonas, Methylophaga, and Shewanella, which could be involved in PBDE degradation.

Abstract
Genotoxicants can be identified as aneugens and clastogens through a micronucleus (MN) assay. The current high-content screening-based MN assays usually discriminate an aneugen from a clastogen based on only one parameter, such as the MN size, intensity, or morphology, which yields low accuracies (70-84%) because each of these parameters may contribute to the results. Therefore, the development of an algorithm that can synthesize high-dimensionality data to attain comparative results is important. To improve the automation and accuracy of detection using the current parameter-based mode of action (MoA), the MN MoA signatures of 20 chemicals were systematically recruited in this study to develop an algorithm. The results of the algorithm showed very good agreement (93.58%) between the prediction and reality, indicating that the proposed algorithm is a validated analytical platform for the rapid and objective acquisition of genotoxic MoA messages.

Abstract
BACKGROUND Hypospadias is a common congenital malformation in males, in which the urethral orifice is found on the ventral side of the penis as a result of incomplete fusion of urethral folds. The etiology of hypospadias is poorly understood, and may be multifactorial, including genetic, endocrine and environmental factors. The steroid 5-alpha-reductase type 2 (SRD5A2) gene, which is mainly expressed in the ventral side of the urethra in the process of male genital development, plays an important role in urethral shaping. OBJECTIVE To investigate, with database searches of related published papers, whether SRD5A2 gene V89L polymorphism has an association with hypospadias risk. METHODS The following databases were searched for relevant papers, and all published case-control studies of hypospadias were used to perform a meta-analysis: PubMed, Embase, Springer Link, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, and Weipu. A quality assessment was performed using the Newcastle-Ottawa scale of a case-control study. To assess the strength of the association under various genetic models, odds ratio (OR) and its 95% confidence interval (CI) were calculated using fixed-effect or random-effects model according to the heterogeneity. Overall and stratified subgroup analyses, including ethnicity, source of controls, sample for DNA extraction, and hypospadias classification, were performed. All data were analyzed using Review Manager 5.3. RESULTS This analysis included six eligible case-control studies with 1130 cases and 1279 controls. Overall, there was a statistically significant association between hypospadias risk and V89L polymorphism for allele contrast (C vs G: OR 1.91, 95% CI 1.13-3.23), P = 0.02), codominant model (CC vs GG: OR 2.97, 95% CI 1.25-7.04, P = 0.01; GC vs GG: OR 2.36, 95% CI 1.35-4.13, P = 0.003), dominant model (GC + CC vs GG: OR 2.46, 95% CI 1.28-4.72, P = 0.007), and recessive model (CC vs GC + GG: OR 1.91, 95% CI 1.00-3.66, P = 0.05). Moreover, there was also a statistically significant association in some subgroups. The positive results are shown in the Summary Table. CONCLUSION This meta-analysis suggested that the V89L polymorphism definitely increases the risk of hypospadias, and the C allele is a genetic risk factor for hypospadias occurrence.

Abstract
OBJECTIVES Childhood obesity is a risk factor for non-alcoholic fatty liver disease and poses important public health issues for children. Racial differences in alanine aminotransferase (ALT) levels among children have not been described. This study aimed to identify racial differences in upper limit normal (ULN) ALT levels and evaluate the effect of obesity on elevated levels in children without other metabolic risk factors. METHODS National Health and Nutrition Examination Surveys and clinical data from the Loyola University Health System were used to determine ULN ALT by race and gender. Quantile regression was used to evaluate the impact of obesity on elevated ALT and to identify potential risk factors for ALT above the ULN. RESULTS Upper limit normal (ULN) ALT was approximately 28.0 and 21.0-24.0 U/L for boys and girls, respectively. No significant difference in ULN ALT across race was observed. Obesity was significantly associated with elevated ALT; obese children with elevated ALT had values 10 U/L higher than normal-weight children. CONCLUSIONS Racial differences in ALT levels among adults are not evident in children. Obesity, in the absence of metabolic risk factors and other causes of liver disease, is associated with elevated ALT, providing evidence against the concept of healthy obesity in children.

Abstract
UNLABELLED We identified a novel large fragment deletion from intron 9 to 3'UTR in PLS3 (E10-E16del) in one Chinese boy with X-linked early-onset osteoporosis and vertebral fractures, which expanded the pathogenic spectrum of X-linked early-onset osteoporosis. Treatment with zoledronic acid was beneficial for increasing BMD and reshaping the vertebral bodies of this patient. INTRODUCTION X-linked early-onset osteoporosis is a rare disease, which is characterized by low bone mineral density (BMD), vertebral compression fractures (VCFs), and/or long bone fractures. We aimed to detect the phenotype and the underlying pathogenic mutation of X-linked early-onset osteoporosis in a boy from a nonconsanguineous Chinese family. METHODS We investigated the pathogenic mutation of the patient with X-linked early-onset osteoporosis by targeted next-generation sequencing and confirmed it by Sanger sequencing. We also observed the effects of zoledronic acid on fracture frequency and BMD of the patient. RESULTS Low BMD and multiple VCFs were the main phenotypes of X-linked early-onset osteoporosis. We identified a total of 12,229 bp deletion in PLS3, involving intron 9 to the 3'UTR (E10-E16 del). This large fragment deletion might be mediated by Alu repeats and microhomology of 26 bp at each breakpoint junction. Zoledronic acid treatment could significantly increase the Z-score of BMD and reshape the compressed vertebral bodies. CONCLUSION We identified a large fragment deletion mutation in PLS3 for the first time and elucidated the possible mechanism of the deletion, which led to X-linked early-onset osteoporosis and multiple vertebral fractures. Our findings would enrich the etiology spectrum of this rare disease.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most common and malignant carcinoma worldwide, and the incidence and mortality are increasing rapidly. Immunotherapy targeting programmed death 1/programmed death ligand 1 (PD-L1) signaling has shown prominent clinical effects in treating NSCLC; however, a poor understanding of the associated regulating molecular mechanisms of PD-L1 has become one of the biggest obstacles for further improving efficacy. Bridging integrator-1 (BIN1) can regulate numerous cancer-related molecules to exert multiple tumor-suppressing effects by either interacting or not interacting with c-MYC. In the present study, we observed that there exists a negative correlation between the expression of PD-L1 and BIN1 in NSCLC tissues. The expression levels of BIN1 and PD-L1 were significantly related to the tumor, lymph node and metastasis grade (TNM) stage, invasion range and lymph node metastasis. Simultaneously, for NSCLC patients, the expression statuses of BIN1 and PD-L1 might be independent prognostic factors. Furthermore, the expression of tumor-infiltrating lymphocytes was positively associated with BIN1 expression and negatively related to PD-L1 expression in NSCLC tissues. Importantly, we showed that PD-L1 was under the control of BIN1. In addition, the overexpression of BIN1 could inhibit the c-MYC and epithelial growth factor receptor (EGFR)-dependent PD-L1 expression and reverse the suppressive immuno-microenvironment in vivo. Taken together, our findings indicated that BIN1 restoration in NSCLC could reverse PD-L1-mediated immune escape by inactivating the c-MYC and EGFR/mitogen-activated protein kinase pathways.

Abstract
Fluoride, which is often added to toothpaste or mouthwash in order to protect teeth from decay, may be a novel therapeutic approach for acceleration of periodontal regeneration. Therefore, we investigated the effects of fluoride on proliferation and mineralization in human periodontal ligament cells in vitro. The periodontal ligament cells were stimulated with various concentrations of NaF added into osteogenic inductive medium. Immunohistochemistry of cell identification, cell proliferation, alkaline phosphatase (ALP) activity assay, Alizarin red S staining and quantitative real-time-polymerase chain reaction (RT-PCR) were performed. Moderate concentrations of NaF (50-500 μmol/L) had pro-proliferation effects, while 500 μmol/L had the best effects. ALP activity and calcium content were significantly enhanced by 10 μmol/L NaF with osteogenic inductive medium. Quantitative RT-PCR data varied in genes as a result of different NaF concentrations and treatment periods. We conclude that moderate concentrations of NaF can stimulate proliferation and mineralization in periodontal ligament cells. These in vitro findings may provide a novel therapeutic approach for acceleration of periodontal regeneration by addition of suitable concentrations of NaF into the medication for periodontitis treatment, i.e., into periodontal packs and tissue patches.

Abstract
Serum prostate-specific antigen (PSA) is a diagnostic biomarker of prostate cancer and is possibly associated with obesity. This study aimed to explore the relationships between obesity indicators [body mass index (BMI) and waist circumference (WC)] with PSA in Chinese men. A cross-sectional study of men aged 30-85 years undergoing prostate cancer screening was conducted from August 2008 to July 2013 in Xi'an, China. Data were obtained from clinical reports, condition was recorded based on self-report including demographics, weight, height, and WC (>90 cm=obese). Fasting blood glucose (FBG) and prostate volume (PV) were assessed clinically. Patients were grouped by BMI (normal=22.9, overweight=23-27.4, obese≥27.5 kg/m2). PSA parameters of density (PSAD), PSA serum level, and PSA increasing rate per year (PSAR) were calculated per BMI and age groups (30-40, 41-59, 60-85 years). Obesity indicators (BMI and WC) and PSA parameter relationships were modeled by age-stratified linear regression. Of 35,632 Chinese men surveyed, 13,084 were analyzed, including 13.44% obese, 57.44% overweight, and 29.12% normal weight, according to BMI; 25.84% were centrally (abdominally) obese according to WC. BMI and WC were negatively associated with all PSA parameters, except PSAD and PSAR [P<0.05, BMI: β=-0.081 (95%CI=-0.055 to -0.036), WC: β=-0.101 (-0.021 to -0.015)], and independent of FBG and PV (P<0.05) in an age-adjusted model. In conclusion, obesity was associated with lower PSA in Chinese men. Therefore, an individual's BMI and WC should be considered when PSA is used to screen for prostate cancer.

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
The angoumois grain moth, Sitotroga cerealella, is one of the most serious stored-grain pests worldwide. Control of this moth may be achieved by interfering with olfactory pathways to disrupt male-female communication with sex pheromones, using plant volatiles like garlic or its active substances. Here, three odorant-binding protein (OBP) genes [namely Si. cerealella general OBP 1 (ScerGOBP1), ScerGOBP2 and Si. cerealella pheromone-binding protein (ScerPBP)] were cloned from Si. cerealella antennae, and quantitative real-time PCR showed that these genes were predominantly expressed in adult antennae. ScerPBP expression was male-biased, but ScerGOBP1 and ScerGOBP2 were similar between sexes. The results of competitive binding assays indicated that a garlic substance, diallyl trisulphide (DATS), had similar or even higher binding affinity to ScerPBP than Si. cerealella sex pheromone, 7Z, 11E-hexadecadien-1-ol acetate (HDA). In olfactometer bioassays, DATS significantly reduced the response of adults to HDA when they were exposed to air filled with HDA and DATS. Surprisingly, ScerGOBP2, which is postulated to be involved in the detection of general odours, displayed higher affinity with HDA than did ScerPBP, indicating that ScerGOBP2 may also have a role in pheromone perception. These data suggest that DATS may interfere with recognition of female-produced sex pheromone, disrupting female and male mating behaviour and resulting in a new idea for controlling stored grain pests.
