Abstract
Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase Ⅲ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage ⅢA-ⅣA ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.

Immune system‑associated genes increase malignant progression and can be used to predict clinical outcome in patients with hepatocellular carcinoma. Int J Oncol 2020; 56:1199-1211. [PMID: 32319580 PMCID: PMC7115743 DOI: 10.3892/ijo.2020.4998] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Accepted: 02/07/2020] [Indexed: 02/05/2023] Open
Abstract
Hepatocellular carcinoma (HCC) is one of the most malignant types of cancer, and is associated with high recurrence rates and a poor response to chemotherapy. Immune signatures in the microenvironment of HCC have not been well explored systematically. The aim of the present study was to identify prognostic immune signatures and build a nomogram for use in clinical evaluation. Using bioinformatics analysis, RNA‑seq data and overall survival (OS) information on 370 HCC cases from TCGA and 232 HCC cases from ICGC were analyzed. The differential expression of select immune genes, based on previously published studies, between HCC and adjacent tissue were analyzed using the limma package in R. Enrichment of pathways and gene ontology analysis was performed using clusterProfiler. Subsequently, univariate Cox regression analysis, Lasso penalty linear regression and multivariate Cox regression models were used to construct a model for immune risk score (IRS). The R packages, survival and survivalROC, were used to plot survival and the associated receiver operating characteristic curves. Infiltration of immune cells was calculated using Tumor IMmune Estimation Resource, with significance examined using a Pearson's correlation test. P<0.05 was considered significant. Based on the analysis, expression of 200 immune genes were upregulated and 47 immune genes were downregulated immune genes. In the multivariate Cox model, 5 genes (enhancer of zest homology 2, ferritin light chain, complement factor H related 3, isthmin 2, cyclin dependent kinase 5) were used to generate the IRS. By stratifying according to the median IRS, it was shown that patients with a high IRS had poor OS rates after 1, 2, 3 and 5 years, and this result was consistent across the testing, training and independent validation cohorts. Additionally, the IRS was correlated with the abundance of infiltrating immune cells. The nomogram built using IRS and clinical characteristics, was able to predict 1, 3 and 5 year OS with area under the curve values of >0.8. These results suggest that the model developed to calculate the IRS may be used to monitor the effectiveness of treatment strategies and for prognostic prediction.

Abstract
Objective: To investigate the differences in efficacy between drug-eluting beads transbronchial arterial chemoembolization (DEB-BACE) combined with systemic chemotherapy and systemic chemotherapy alone for unresectable lung squamous cell carcinoma. Methods: Totally 60 cases of unresectable lung squamous cell carcinoma undergoing systemic chemotherapy in Yancheng Third People Hospital were retrospectively selected as the research object. According to patients' wishes, they were divided into chemotherapy-only group (group A) and combined treatment group (group B). Group A received gemcitabine combined with cisplatin chemotherapy. DEB-BACE was applied in the first half, and systemic chemotherapy was administered in the second half (starting 3 d after BACE). The first half and the second half of the chemotherapy dose were 1/2 of the drug dose in the chemotherapy alone group. The short-term efficacy, incidence of toxic side effects, peripheral blood T lymphocyte subsets, serum vascular endothelial growth factor (VEGF) levels, and survival time were compared between the two groups. Results: After 2 cycles of treatment, the total effective rates of group A and group B were 50.0% (15/30) and 76.7% (23/30) (P<0.05), the incidence of nausea and vomiting (63.3% vs 20.0%), decreased appetite (76.7% vs 43.3%), hair loss (86.7% vs 40.0%), and bone marrow suppression (40.0% vs 10.0%) in group A were higher than in group B (all P<0.05). After 2 cycles of treatment, the levels of CD3(+), CD4(+)and CD4(+)/CD8(+)in the two groups were higher than before treatment (group A: 47.7%±6.6% vs 52.3%±7.7%, 31.5%±4.9% vs 34.7%±5.8%, 1.05±0.24 vs 1.18±0.32; group B: 49.2%±7.0% vs 62.0%±14.0%,29.2%±5.5% vs 42.2%±7.3%, 1.07±0.26 vs 1.39±0.42; all P<0.05), while the level of CD8(+)was lower than before treatment (group A: 30.4%±5.4% vs 24.5%±4.8%; group B: 29.5%±4.1% vs 21.1%±4.5%; all P<0.05). The CD3(+), CD4(+), and CD4(+)/CD8(+) levels in group A were lower than those in group B (P<0.05), while CD8(+)level was higher than in group B (P<0.05). After 2 cycles of treatment, the VEGF levels in the two groups were lower than before treatment (group A: (423±85) vs (352±64) ng/L; group B: (404±114) vs (296±66) ng/L; P<0.05), and the VEGF level in group A was higher than that in group B (P<0.05). The 1-year survival rates of groups A and B were 54.9% and 77.9%, and the 2-year survival rates were 17.2% and 41.7% (Log rank χ(2)=4.750, P=0.029). Conclusion: DEB-BACE combined with systemic chemotherapy is superior to systemic chemotherapy in the treatment of unresectable lung squamous cell carcinoma. It can reduce toxic and side effects, improve immune function and prolong survival time, which is worthy of clinical application.

Abstract
Aristolochic acid (AA) is a compound extracted from the Aristolochia species of herbs. AA exposure is associated with kidney injury known as aristolochic acid nephropathy (AAN). Proximal tubular epithelial cell (PTEC) is the primary target of AA and rich in mitochondria. Recently, increasing evidence suggests that mitochondrial dysfunction plays a critical role in the pathogenesis of kidney disease. However, the status of mitochondrial function in PTEC after exposure to AA remains largely unknown. The aim of this study was to explore the effect of aristolochic acid I (AAI) on cell apoptosis and mitochondrial function in PTEC. Normal rat kidney-52E (NRK-52E) cells were exposed to different concentrations of AAI for different time periods. Cell viability was detected by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide, cell apoptosis was analyzed by flow cytometry, and the expression of cleaved caspase-3 by Western blotting. Mitochondrial function was evaluated by reactive oxygen species (ROS), mitochondrial membrane potential (MMP), mitochondrial DNA (mtDNA) copy number, and adenosine triphosphate (ATP). It was found that AAI reduced cell viability and increased cell apoptosis in a dose- and time-dependent manner. In parallel to increased apoptosis, NRK-52E cell manifested signs of mitochondrial dysfunction in response to AAI treatment. The data indicated that AAI could increase ROS level, lower MMP, decrease mtDNA copy number, and reduce ATP production. In addition, Szeto-Schiller 31, a mitochondria-targeted antioxidant peptide, attenuated AAI-induced mitochondrial dysfunction and apoptosis. Our study depicted significant aberrant of mitochondrial function in AAI-treated NRK-52E cell, which suggested that mitochondrial dysfunction may be involved in AAI-induced apoptosis in PTEC.

Separation of oil sands process water organics and inorganics and examination of their acute toxicity using standard in-vitro bioassays. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 695:133532.

Abstract
Oil sands process water (OSPW) contains complex components of inorganics and organics. This is the first study that separated OSPW inorganic and organic fractions and examined their relative acute toxicity when compared with the original whole OSPW using an in-vitro cell-based bio-indicator system. The separation of OSPW inorganic and organic fractions would be conducive to the understanding of the toxic contribution of organic and inorganic fractions as well as the identification and treatment of organic fractions. In this research, we demonstrated that the highest organic fraction extraction was obtained using HLB solid phase extraction with 95.4 ± 0.7% of dissolved organic carbon (DOC) and 90.0 ± 5.3% of naphthenic acid (NA) recovered from OSPW, which were higher than those obtained using the traditional dichloromethane liquid-liquid extraction (48.8 ± 0.2% of DOC and 81.0 ± 2.6% of NA recovery) or other SPE cartridges tested. We also reported the first isolation method for OSPW inorganic fraction by removing 96.1 ± 0.2% of DOC in OSPW using granular activated carbon. The difference of other parameters such as pH, alkalinity, conductivity, and concentration of detected ions between OSPW and isolated inorganic fraction was negligible. The acute toxicity of whole OSPW, separated OSPW inorganic fraction and organic fraction, and the reconstituted fractions were assessed using in-vitro bioassays with RAW 264.7 mouse macrophage cell lines. OSPW organic fraction demonstrated significant cytotoxicity at 14 mg/L O2-NA and affected the cellular metabolic activity at 10 mg/L of O2-NAs. No significant cytotoxicity or effect on cellular metabolic activity was observed for whole OSPW, OSPW inorganic fraction and the reconstituted fractions. Overall, this study provides the procedure for the isolation of the major components of OSPW (i.e., organics and inorganics), which allows the assessment of their relative toxicological effects using a standard in-vitro bioassay and would allow more accurate characterization and treatment study for each fraction in OSPW.

Comparison of UV/Persulfate and UV/H 2O 2 for the removal of naphthenic acids and acute toxicity towards Vibrio fischeri from petroleum production process water.

Abstract
The ultraviolet light-activated persulfate process (UV/Persulfate) has received much attention in recent years as a novel advanced oxidation method for the treatment of municipal and industrial wastewater. This work investigated the UV/Persulfate and UV/H2O2 processes for the treatment of real oil sands process water (OSPW) at ambient pH condition using a medium pressure mercury lamp (emission between 200 and 530 nm). The degradation performances towards fluorophore organic compounds and naphthenic acids (NAs) in OSPW were evaluated using synchronous fluorescence spectrometry and ultra performance liquid chromatography time-of-flight mass spectrometry, respectively. Compared to the UV/H2O2 process, the UV/Persulfate process exhibited higher efficiency to remove both NAs and fluorophore organic compounds. Under 40 min of UV exposure and incident irradiance of 3.50 mW cm-2, fluorophore organic compounds were greatly degraded by UV/Persulfate (2 mM) and two- and three-ring fused organics were completely removed. 59.4%, 83.8% and 92.2% of O2-NAs in OSPW were removed with persulfate dosages of 0.5, 2, and 4 mM, respectively. The removal efficiency decreased along with the number of oxygen atoms in NAs (83.8%, 49.3%, and 46.8% for O2-, O3-, and O4-NAs, respectively) with 2 mM of persulfate, because of the formation of oxidized NAs in the same process. The structure-reactivity of O2-NA compounds fitted pseudo-first order kinetics in UV/Persulfate process with the rate constants ranging from 0.0156 min-1 to 0.1511 min-1. NAs with higher carbon numbers and double bond equivalence were more reactive in the UV/Persulfate oxidation process. The acute toxicity of OSPW to Vibrio fischeri was significantly reduced after the UV/Persulfate and UV/H2O2 treatments. Overall results demonstrated that the UV/Persulfate oxidation can be an effective alternative for future reclamation of OSPW.

Abstract
Exposure to oil sands process-affected water (OSPW), a by-product of Canadian oil sands mining operations, can cause both acute and chronic adverse effects in aquatic life. Ozonation effectively degrades naphthenic acids in OSPW, mitigating some of the toxicological effects of exposure. In this study we examined the effect of developmental exposure to raw and ozonated OSPW had on the breeding success, prey capture, and alarm cue response in fish months/years after exposure and the transgenerational effect exposure had on gene expression, global DNA methylation, and larval basal activity. Exposure to raw and ozonated OSPW had no effect on breeding success, and global DNA methylation. Exposure altered the expression of vtg and nkx2.5 in the unexposed F1 generation. Exposure to both raw and ozonated OSPW had a transgenerational impact on larval activity levels, anxiety behaviors, and maximum swim speed compared to the control population. Prey capture success was unaffected, however, the variability in the behavioral responses to the introduction of prey was decreased. Fish developmentally exposed to either treatment were less active before exposure and did not have an anxiety response to the alarm cue hypoxanthine-3-n-oxide. Though ozonation was able to mitigate some of the effects of OSPW exposure, further studies are needed to understand the transgenerational effects and the implications of exposure on complex fish behaviors.

Abstract
OBJECTIVE To investigate the effects of miR-519d on the 5-fluorouracil resistance in colorectal cancer cells and to explore the mechanism. MATERIALS AND METHODS Colorectal cancer cells HCT116 and SW480 were transfected with miR519d-mimic or siCCND1 by transient transfection. The sensitivity of cells to 5-Fu was assayed by MTT assay. Dual luciferase assay was used to examine the effect of CCND1 on the sensitivity of cells to 5-Fu mediated by miR-519d. RESULTS MiR-519d was overexpressed in colorectal cancer cells after transient transfection with miR-519d mimics. Overexpression of miR-519d increased the sensitivity of colorectal cancer cells to 5-Fu. MiR-519d negatively regulated the expression of CCND1 via directly bound to CCND1 3`UTR. si-CCND1 could downregulate the CCND1 expression in colorectal cancer HCT116 and SW480 cells. si-CCND1 increased the sensitivity of colorectal cancer cells to 5-Fu. CONCLUSIONS miR-519d inhibits the expression of CCND1 and then plays a role in alleviating 5-Fu resistance in colorectal cancer cells.

Abstract
Chronic rhinosinusitis (CRS) is one of the most common types of respiratory disease and affects a large proportion of the population worldwide. The clinical differences between CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP) facilitate studies on the development of polyps. In the present study, next-generation sequencing was performed to identify differentially expressed microRNAs (miRNAs/miRs) in CRSwNP vs. CRSsNP tissues and subsequently validated the expression of selected genes using reverse transcription-quantitative polymerase chain reaction analysis. In total, 6 miRNAs were identified to be downregulated in the CRSwNP samples compared with those in the CRSsNP samples. The predicted targets of these miRNAs were determined to be enriched in a number of signaling pathways, including the ErbB, Ras, cyclic adenosine monophosphate and Janus kinase (Jak)/signal transducer and activator of transcription (STAT) pathways. The expression of miR-4492 and that if its targets predicted by a bioinformatics analysis, tumor necrosis factor α (TNF-α) and interleukin (IL)-10, was validated in 96 clinical specimens. miR-4492 was downregulated and IL-10 was upregulated in CRSwNP vs. CRSsNP tissues, and an inverse correlation between miR-4492 and IL-10 was determined in CRS tissues; however no difference was identified in the expression of TNF-α between the different groups. The present results indicate that the miR-4492/IL-10 interaction in the Jak/STAT signaling pathway may be one of the key mechanisms in CRSwNP.

Abstract
OBJECTIVE FoxO3a is a well-defined tumor suppressor gene in the forkhead transcription factor O subfamily (FoxO), and its reduction is related to the occurrence of various tumors. It was found that miR-223 expression is abnormally elevated in pancreatic cancer tissues. Bioinformatics analysis revealed a targeted complementary binding relationship between miR-223 and FoxO3a. This study explored whether miR-155 regulates the expression of FoxO3a and affects the proliferation, apoptosis, and cisplatin (CDDP) resistance of oral cancer cells. MATERIALS AND METHODS Dual-Luciferase reporter gene assay validated the targeted relationship between miR-223 and FoxO3a. The CDDP-resistant pancreatic cancer cell line BXPC3/CDDP was established, and the expressions of miR-223 and FoxO3a were compared. BXPC3/CDDP cells were divided into miR-NC group and miR-223 inhibitor group. QRT-PCR was adopted to test miR-223 and FoxO3a mRNA expressions. Western blot was performed to determine FoxO3a protein expression. Cell apoptosis was detected by flow cytometry and cell proliferation was detected by EdU staining. RESULTS There was a targeted regulatory relationship between miR-223 and FoxO3a mRNA. The expression of miR-223 was significantly higher, while the expression of FoxO3a mRNA and protein was significantly lower in BXPC3/CDDP cells than that in BXPC3 cells. Cell Counting Kit-8 (CCK-8) experiments showed that the same concentration of CDDP exhibited significantly lower proliferation inhibition in BXPC3/CDDP cells than BXPC3 cells. Compared with miR-NC group, transfection of miR-223 inhibitor significantly increased the expression of FoxO3a in BXPC3/CDDP cells, which significantly attenuated cell proliferation and enhanced apoptosis in CDDP-treated cells. CONCLUSIONS Increased expression of miR-233 was associated with CDDP resistance in pancreatic cancer cells. Inhibition of miR-223 expression upregulated FoxO3a expression, restrained pancreatic cancer cell proliferation, promoted cell apoptosis, and enhanced CDDP sensitivity in pancreatic cancer cells.

[PMID: 30978552 DOI: 10.1016/j.scitotenv.2019.04.042] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 04/03/2019] [Accepted: 04/03/2019] [Indexed: 06/09/2023]
Abstract
Distinct naphthenic acid (NA) species were isolated from oil sands process water (OSPW) into 20 fractions via silver-ion solid phase extraction, prior to treatment using potassium ferrate(VI). Untreated and treated fractions F1-F20 were characterized using ultra performance liquid chromatography traveling-wave ion mobility time-of-flight mass spectrometry to identify classical NAs (aliphatic O2-NAs mainly found in fractions F1-F4), aromatic NAs (aromatic O2-NAs in F6-F9), oxidized NAs (O3-, O4-, and O5-NAs in F14-F17), and sulfur-containing NAs (F16-F19). The Fe(VI) oxidation reactivity of individual NA species was studied with minimized confounding effects from the complicated OSPW matrix. Aliphatic and aromatic O2-NAs were found to have different reactivity towards Fe(VI) oxidation, with removals ranging from <50% up to 90% at 200 mg/L ferrate dose. The O3-NAs and O4-NAs from raw OSPW were recalcitrant species with slight degradation under Fe(VI) oxidation conditions. The Fe(VI) oxidation of O2-NAs generated new O3-NAs as byproducts or intermediate byproducts which finally resulted in more oxygen-rich Ox-NAs as the final byproducts depending on the Fe(VI) doses. Besides the obtained knowledge on chemical reactivity, current methodology (i.e., treatment of Ag-ion fractions of OSPW versus raw OSPW) could be applied to evaluate other treatment approaches as well as toxicity of distinct NA species for environmental applications.

Transcriptome analysis of the endometrium from Chinese Erhualian sows that differ in calcium ion concentration and litter size. Anim Genet 2019; 50:326-333.

Abstract
Embryonic survival rate, an important factor in the fecundity of sows, is affected by endometrium-secreting histotroph. A higher concentration of calcium ion has been observed in the uterus of highly prolific Erhualian sows (EH) compared with those of less prolific (EL) sows. This suggests that EH sows have better establishment and maintenance of pregnancies, thus increasing embryonic survival rate during the peri-implantation period. To understand the mechanisms of how the endometrium-secreting histotroph affects embryonic survival rate during the Erhualian peri-implantation period, the expression patterns of endometrial mRNA in the EH and EL sows on day 12 of gestation were analyzed using RNA sequencing technology. A total of 164 differentially expressed genes (DEGs) were identified (Padj < 0.05, |log2 (FC)| ≥ 1), including 46 upregulated and 118 downregulated genes in EH compared to EL. Gene Ontology enrichment indicated that a subset of DEGs was involved in calcium ion binding and cell adhesion. Solute carrier family 8 member A3 and solute carrier family 24 member 4, identified as upregulated genes (Padj < 0.05) in EH, were considered key candidate genes expressed in the endometrium affecting embryonic survival rate during the peri-implantation period. The results improve understanding of the genetic mechanism underlying the variation in litter size of Erhualian pigs during the peri-implantation period.

Assessment of ozonation reactivity of aromatic and oxidized naphthenic acids species separated using a silver-ion solid phase extraction method. CHEMOSPHERE 2019; 219:313-320.

Abstract
Owing to the complexity of naphthenic acids (NAs) in oil sands process water (OSPW), previous ozone-treatment studies mainly investigated the removal of classical NAs (aliphatic O2-NAs) and the understanding of ozonation reactivity of other NA species has been limited. This work utilized a silver-ion solid phase extraction (SPE) approach to separate individual NA species into 20 fractions before subsequent ozone treatment. The ozonation reactivity of aromatic and oxidized NA species in isolated fractions was studied for the first time. Untreated and ozone-treated SPE fractions were characterized using ultra performance liquid chromatography ion mobility time-of-flight mass spectrometry. The removals of aliphatic O2-NAs (Fraction 3), aromatic O2-NAs (Fraction 8), O3-NAs (Fraction 11), and O4-NAs (Fraction 17) with an applied ozone dosage of 16.8 mg L-1 were 97.2%, 94.7%, 59.4% and 44.7%, respectively. The results showed that aromatic and oxidized NAs with larger carbon number were favorably removed during ozonation treatment. Comparison of the ozone utilization efficiency for different NA species indicated that the degradation of oxidized NAs consumed more ozone in molar ratio than the degradation of classical and aromatic NAs. The reactivity of oxidized NAs was lower than that of classical NAs because the former consumed more ozone in molar ratio during reactions. Knowing the reactivity of different NA species is crucial for the design of ozonation systems targeting species with high toxicity. Moreover, the utilization of silver-ion SPE pre-separation approach has been demonstrated for future studies investigating the degradation mechanism of distinct NA species under other treatment conditions.

Abstract
Oral tongue squamous cell carcinoma (OTSCC) is the most common type of oral cancer. Despite advances in knowledge regarding the genome-scale gene expression pattern of oral cancer, the molecular portrait of OTSCC biology has remained unclear over the last few decades. Furthermore, studies concerning OTSCC gene-expression profiles are limited or inconsistent owing to tissue heterogeneity in single-cohort studies. Consequently, the present study integrated the profile datasets of three cohorts in order to screen for differentially expressed genes (DEGs), and subsequently identified the potential candidate genes and pathways in OTSCC through gene enrichment analysis and protein-protein interaction (PPI) network construction. Using the selected Gene Expression Omnibus datasets GSE13601, GSE31056 and GSE78060, 206 DEGs (125 upregulated and 81 downregulated) were identified in OTSCC, principally associated with extracellular matrix (ECM) organization and the phosphoinositide 3-kinase/protein kinase B signaling pathway. Furthermore, 146/206 DEGs were filtered into the PPI network and 20 hub genes were sorted. Further results indicated that the two most significant modules filtered from the PPI network were associated with ECM organization and human papillomavirus infection, which are important factors affecting OTSCC pathology. Overall, a set of OTSCC-associated DEGs has been identified, including certain key candidate genes that may be of vital importance for diagnosis, therapy and prevention of this disease.

Abstract
The classical, oxidized, and heteroatomic naphthenic acids (NAs) species were monitored in the oil sands process water (OSPW) and groundwater from the active oil sands operation area, using solid phase extraction sample preparation and high resolution mass spectrometry analysis. Groundwater samples include Pleistocene channel aquifer groundwater (PLCA) and oil sands basal aquifer groundwater (OSBA) from different depth of underground. The concentrations of Ox-NAs decreased from OSPW to PLCA, and then increased from PLCA to OSBA, which is deeper than PLCA. The NAs in PLCA mainly comprised of Ox-NAs and N-NAs and the percentage of S-NAs was negligible. Results revealed relative abundances of individual NA species in total NAs varies among different water layers and the potential environmental impacts are expected to be variable. Principal component analysis results of O2-NAs or O4-NAs could be used for differentiation of water types. O2-NAs with n = 12-16 and |Z| = 4-6, and O4-NAs with n = 14-20 and |Z| = 6-8, were identified as marker compounds that could serve as surrogates of the larger complex NA mixture for source differentiation. This work utilized a combination of sample preparation, instrumental analysis, and statistical analysis methods to obtain knowledge of the occurrence, composition, and transfer of NAs in the groundwater of the Alberta oil sands operation area.

Abstract
AIM We aim to investigate the incidence and associated factors of vitamin D deficiency, a seldom reported factor, in patients with stages 1 and 2 chronic kidney disease (CKD) in southern China. METHODS We conducted a single-center observational study. Hospitalized patients over 14 years old, who were diagnosed with stages 1 and 2 CKD and had their serum 25-hydroxyvitamin D [25 (OH) D] measured, were included. Patients were divided into vitamin D deficient and non-deficient groups depending on the cutoff serum 25 (OH) D value of 37 nmol/L. Clinical and biochemical parameters were evaluated for associated factors of vitamin D deficiency by logistic regression. RESULTS A total of 118 patients were included, of which 62 (52.5%) were vitamin D insufficient and 47 (39.8%) were vitamin D deficient. Using multivariate binary logistic regression analysis, high serum level of gamma-glutamyl transpeptidase (GGT) (OR = 5.163; 95%CI, 1.105-24.130; P = 0.037), dyslipidemia (OR = 3.083; 95%CI, 1.029-9.243; P = 0.044), 24-hour urinary protein excretion (UPE) ≥3.5 g/24 hrs (OR = 5.010; 95%CI, 1.316-19.074; P = 0.018), and treatment with glucocorticoids (OR = 2.973; 95%CI, 1.093-8.084; P = 0.033) were independently associated with vitamin D deficiency. In addition, among different types of nephropathy, minimal change disease (MCD) had the highest incidence (85.7%) of vitamin D deficiency. CONCLUSION Poor vitamin D status is common in patients with stages 1 and 2 CKD in southern China. The incidence of vitamin D deficiency is 39.8%. High serum GGT level, dyslipidemia, 24-hour UPE ≥3.5 g/24 hrs, and treatment with glucocorticoids are independent associated factors of vitamin D deficiency.

Abstract
OBJECTIVES As HIV-positive people age, diagnosis and management of comorbidities associated with ageing are of increasing concern. In this study, we aimed to compare the self-reported prevalences of heart disease, stroke, thrombosis and diabetes in older Australian HIV-positive and HIV-negative gay and bisexual men (GBM). METHODS We analysed data from the Australian Positive & Peers Longevity Evaluation Study (APPLES), a study of a prospectively recruited cross-sectional sample of 228 (51.1%) HIV-positive and 218 (48.9%) HIV-negative GBM, aged ≥ 55 years. Regression methods were used to assess the association of HIV status with self-reported comorbidities. RESULTS Of 446 patients, 389 [200 (51.4%) HIV-positive] reported their disease history. The reported prevalence of comorbidities was higher in the HIV-positive group than in the HIV-negative group: heart disease, 19.5 versus 12.2%; stroke, 7.5 versus 4.2%; thrombosis, 10.5 versus 4.2%; and diabetes, 15.0 versus 9.0%, respectively. In adjusted analyses, HIV-positive GBM had significantly increased odds of reporting heart disease [adjusted odds ratio (aOR) 1.99; P = 0.03] and thrombosis (aOR 2.87; P = 0.01). In our analysis, HIV status was not significantly associated with either age at diagnosis of heart disease (median 53 years for HIV-positive GBM versus 55 years for HIV-negative GBM; P = 0.64) or 5-year cardiovascular disease (CVD) risk estimated using the Framingham risk score. CONCLUSIONS HIV-positive GBM more commonly reported heart disease and thrombosis compared with their HIV-negative peers. These results further highlight the need to understand the impact of HIV on age-related comorbidities in GBM, to guide optimal screening and treatment strategies to reduce the risk of these comorbidities among the HIV-positive population.

Shape Features of the Lesion Habitat to Differentiate Brain Tumor Progression from Pseudoprogression on Routine Multiparametric MRI: A Multisite Study. AJNR Am J Neuroradiol 2018; 39:2187-2193.

Abstract
BACKGROUND AND PURPOSE Differentiating pseudoprogression, a radiation-induced treatment effect, from tumor progression on imaging is a substantial challenge in glioblastoma management. Unfortunately, guidelines set by the Response Assessment in Neuro-Oncology criteria are based solely on bidirectional diametric measurements of enhancement observed on T1WI and T2WI/FLAIR scans. We hypothesized that quantitative 3D shape features of the enhancing lesion on T1WI, and T2WI/FLAIR hyperintensities (together called the lesion habitat) can more comprehensively capture pathophysiologic differences across pseudoprogression and tumor recurrence, not appreciable on diametric measurements alone. MATERIALS AND METHODS A total of 105 glioblastoma studies from 2 institutions were analyzed, consisting of a training (n = 59) and an independent test (n = 46) cohort. For every study, expert delineation of the lesion habitat (T1WI enhancing lesion and T2WI/FLAIR hyperintense perilesional region) was obtained, followed by extraction of 30 shape features capturing 14 "global" contour characteristics and 16 "local" curvature measures for every habitat region. Feature selection was used to identify most discriminative features on the training cohort, which were evaluated on the test cohort using a support vector machine classifier. RESULTS The top 2 most discriminative features were identified as local features capturing total curvature of the enhancing lesion and curvedness of the T2WI/FLAIR hyperintense perilesional region. Using top features from the training cohort (training accuracy = 91.5%), we obtained an accuracy of 90.2% on the test set in distinguishing pseudoprogression from tumor progression. CONCLUSIONS Our preliminary results suggest that 3D shape attributes from the lesion habitat can differentially express across pseudoprogression and tumor progression and could be used to distinguish these radiographically similar pathologies.

Abstract
The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait, deficits of spatial memory and navigation. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). Head impulse test (HIT), video-oculography system (vHIT), crvical/ocular vestibular-evoked myogenic potentials (c/oVEMP) and dynamic visual acuity is an additional test supporting the diagnosis. There are four different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low-and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral Menière's disease, meningitis, or autoimmune diseases; fourth, if possible, prevention, i.e., being very restrictive with the use of ototoxic substances, such as aminoglycosides.

Abstract
Identifying the degree of liver inflammation is critical for therapeutic judgement of patients with chronic hepatitis B (CHB). However, we lack indexes which can accurately predict significant liver inflammation in patients with CHB. This study aimed to develop a simple predictive index for liver inflammation in CHB using routine clinical parameters. A total of 519 patients with CHB who underwent liver biopsy were enrolled and randomly divided into training (n = 346) and validation cohorts (n = 173). Based on routine clinical parameters, gamma-glutamyl transpeptidase (GGT; P = 0.031) and platelets (PLT; P < 0.001) were identified as independent predictors of significant inflammation by multivariable analysis in the training cohort. Accordingly, the GGT to PLT ratio (GPR) was developed to amplify the opposing effects for predicting liver inflammation. In the training cohort, the AUCs of GPR in predicting significant inflammation were 0.791 (95% CI: 0.742-0.839), 0.783 (95% CI: 0.717-0.849) and 0.791 (95% CI: 0.716-0.867) in the entire patients with CHB, HBeAg-positive CHB patients and HBeAg-negative CHB patients, respectively. The diagnostic performance of GPR for significant inflammation was significantly superior to that of alanine aminotransferase (ALT), aspartate transaminase (AST) and GGT in all patients with CHB and HBeAg-positive CHB patients, but was comparable with ALT, AST and GGT in HBeAg-negative CHB patients. In the validation cohort, the diagnostic performance of GPR in assessing significant liver inflammation was also superior to other indexes in all patients with CHB and HBeAg-positive CHB patients, but was comparable with GGT in HBeAg-negative CHB patients. Thus, GPR can be a novel and simple index for predicting significant liver inflammation in CHB, especially for HBeAg-positive CHB.

Abstract
With the ever-increasing amounts of oil sands process-affected water (OSPW) accumulating from Canada's oil sands operations, its eventual release must be considered. As OSPW has been found to be both acutely and chronically toxic to aquatic organisms, remediation processes must be developed to lower its toxicity. Ozone treatment is currently being studied as a tool to facilitate the removal of organic constituents associated with toxicity. Biomarkers (e.g. gene expression) are commonly used when studying the effects of environmental contaminants, however, they are not always indicative of adverse effects at the whole organism level. In this study, we assessed the effects of OSPW exposure on developing zebrafish by linking gene expression to relevant cellular and whole organism level endpoints. We also investigated whether or not ozone treatment decreased biomarkers and any associated toxicity observed from OSPW exposure. The concentrations of classical naphthenic acids in the raw and ozonated OSPW used in this study were 16.9 mg/L and 0.6 mg/L, respectively. Ozone treatment reduced the total amount of naphthenic acids (NAs) in the OSPW sample by 92%. We found that exposure to both raw and ozonated OSPW had no effect on the survival of zebrafish embryos. The expression levels of biotransformation genes CYP1A and CYP1B were induced by raw OSPW exposure, with CYP1B being more highly expressed than CYP1A. In contrast, ozonated OSPW exposure did not increase the expression of CYP1A and only slightly induced CYP1B. A decrease in cardiac development and function genes (NKX2.5 and APT2a2a) was not associates with large changes in heart rate, arrhythmia or heart size. We did not find any indications of craniofacial abnormalities or of increased occurrence of apoptotic cells. Overall, our study found that OSPW was not overtly toxic to zebrafish embryos.

Abstract
OBJECTIVE To compare the in vitro fertilisation (IVF) outcomes of poor ovarian responders among women with laparoscopically diagnosed minimal-mild endometriosis (Group A), moderate-severe endometriosis (Group B) and those without endometriosis (Group C). The comparisons were made separately for age groups younger than 35 years and 35 years or older. DESIGN Retrospective study. SETTING A university-affiliated hospital in Guangzhou, China. POPULATION 495 women younger than 35 years old and 543 women aged 35 or older who had poor ovarian response with or without laparoscopically diagnosed endometriosis. METHODS Poor ovarian response (POR) was diagnosed using the Bologna criteria. First cycle parameters were analysed over the same period of time from January 2011 to October 2014. MAIN OUTCOME MEASURES The primary endpoint was the live birth rate per embryo transfer cycle. Secondary outcome measures were clinical pregnancy rate, cycle cancellation rate and miscarriage rate. RESULTS In women aged 35 or older no differences were found among the three subgroups in terms of live birth rate, clinical pregnancy rate, cycle cancellation rate or miscarriage rate; in women aged younger than 35 years, the clinical pregnancy rates were 62.96, 45.45 and 43.27% for Groups A, B and C, respectively (P = 0.028). The live birth rate, cycle cancellation rate and miscarriage rate were not significantly different. Compared with the older group of women, the younger women had a significantly higher live birth rate (P < 0.001). CONCLUSIONS A woman's age is the most important factor governing the live birth rate with IVF. Endometriosis has no consistent impact on IVF outcomes in women with POR. TWEETABLE ABSTRACT Endometriosis has no negative impact on IVF outcomes in women with poor ovarian response.

Abstract
Vitrification of embryos is a routine procedure in IVF (in vitro fertilization) laboratories. In the present study, we aimed to investigate the effect of vitrification on mouse preimplantation embryo development in vitro, and effect on the epigenetic status of imprinted gene Grb10 in mouse embryos. The blastocyst formation rate for vitrified 8-cell embryos was similar to the non-vitrified 8-cell embryos, whereas the blastocyst hatching rate was lower than that of the non-vitrified group. The expression level of Grb10 major-type transcript decreased significantly in vitrified blastocysts compared with non-vitrified and in vivo blastocysts. Moreover, the global DNA methylation level in 8-cell embryos and blastocysts, and the DNA methylation at CpG island 1 (CGI1) of Grb10 in blastocysts were also significantly decreased after vitrification. In vitro culture condition had no adverse effect, except for on the DNA methylation in Grb10 CGI1. These results suggest that vitrification may reduce the in vitro development of mouse 8-cell embryos and affect the expression and DNA methylation of imprinted gene Grb10.

Abstract
The modification of the local structure in cubic perovskite KTaO3 irradiated with 3 MeV and 1.1 GeV Au ions is studied by Raman and x-ray absorption spectroscopy, complemented by density functional theory (DFT) calculations. In the case of irradiation with 3 MeV Au ions where displacement cascade processes are dominant, the Ta L3-edge x-ray absorption measurements suggest that a peak corresponding to the Ta-O bonds in the TaO6 octahedra splits, which is attributed to the formation of TaK antisite defects that are coupled with oxygen vacancies, V O. This finding is consistent with the DFT calculations. Under irradiation with 1.1 GeV ions, the intense ionization and electronic energy deposition lead to a blue shift and an intensity reduction of active Raman bands. In the case of sequential irradiations, extended x-ray absorption fine structure measurements reveal a decrease in concentration of coupled TaK-V O defects under subsequent irradiation with 1.1 GeV Au ions.

Abstract
Ghrelin is a gastric acyl-peptide that plays an important role in cell proliferation. In the present study, we explored the role of ghrelin in A549 cell proliferation and the possible molecular mechanisms. We found that ghrelin promotes A549 cell proliferation, knockdown of the growth hormone secretagogue receptor (GHSR) attenuated A549 cell proliferation caused by ghrelin. Ghrelin induced the rapid phosphorylation of phosphatidylinositol 3-kinase (PI3K), Akt, ERK, mammalian target of rapamycin (mTOR) and P70S6K. PI3K inhibitor (LY 294002), ERK inhibitor (PD98059) and mTOR inhibitor (Rapamycin) inhibited ghrelin-induced A549 cell proliferation. Moreover, GHSR siRNA inhibited phosphorylation of PI3K, Akt, ERK, mTOR and P70S6K induced by ghrelin. Akt and mTOR/P70S6K phosphorylation was inhibited by LY 294002 but not by PD98059. These results indicate that ghrelin promotes A549 cell proliferation via GHSR-dependent PI3K/Akt/mTOR/P70S6K and ERK signaling pathways.

Abstract
Aims The aims of this study were to compare the efficacy of two agents,
aspirin and warfarin, for the prevention of venous thromboembolism
(VTE) after simultaneous bilateral total knee arthroplasty (SBTKA),
and to elucidate the risk of VTE conferred by this procedure compared
with unilateral TKA (UTKA). Patients and Methods A retrospective, multi-institutional study was conducted on 18
951 patients, 3685 who underwent SBTKA and 15 266 who underwent
UTKA, using aspirin or warfarin as VTE prophylaxis. Each patient
was assigned an individualised baseline VTE risk score based on
a system using the Nationwide Inpatient Sample. Symptomatic VTE,
including pulmonary embolism (PE) and deep vein thrombosis (DVT),
were identified in the first 90 days post-operatively. Statistical
analyses were performed with logistic regression accounting for
baseline VTE risk. Results The adjusted incidence of PE following SBTKA was 1.0% (95% confidence
interval (CI) 0.86 to 1.2) with aspirin and 2.2% (95% CI 2.0 to
2.4) with warfarin. Similarly, the adjusted incidence of VTE following
SBTKA was 1.6% (95% CI 1.1 to 2.3) with aspirin and 2.5% (95% CI
1.9 to 3.3) with warfarin. The risk of PE and VTE were reduced by
66% (odds ratio (OR) 0.44, 95% CI 0.25 to 0.78) and 38% (OR 0.62,
95% CI 0.38 to 1.0), respectively, using aspirin. In addition, the risk
of PE was 204% higher for patients undergoing SBTKA relative to
those undergoing UTKA. For each ten-point increase in baseline VTE
risk, the risk of PE increased by 25.5% for patients undergoing
SBTKA compared with 10.5% for those undergoing UTKA. Patients with
a history of myocardial infarction or peripheral vascular disease had
the greatest increase in risk from undergoing SBTKA instead of UTKA. Conclusion Aspirin is more effective than warfarin for the prevention of
VTE following SBTKA, and serves as the more appropriate agent for
VTE prophylaxis for patients in all risk categories. Furthermore,
patients undergoing SBTKA are at a substantially increased risk
of VTE, even more so for those with significant underlying risk
factors. Patients should be informed about the risks associated
with undergoing SBTKA. Cite this article: Bone Joint J 2018;100-B(1

Characterization and determination of naphthenic acids species in oil sands process-affected water and groundwater from oil sands development area of Alberta, Canada. WATER RESEARCH 2018; 128:129-137.

Abstract
This work reports the monitoring and assessment of naphthenic acids (NAs) in oil sands process-affected water (OSPW), Pleistocene channel aquifer groundwater (PLCA), and oil sands basal aquifer groundwater (OSBA) from an active oil sands development in Alberta, Canada, using ultra performance liquid chromatography time-of-flight mass spectrometry (UPLC-TOF-MS) analysis with internal standard (ISTD) and external standard (ESTD) calibration methods and Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) for compositional analysis. PLCA was collected at 45-51 m depth and OSBA was collected at 67-144 m depth. Results of Ox-NA concentrations follow an order as OSPW > OSBA > PLCA, indicating that occurrences of NAs in OSBA were likely related to natural bitumen deposits instead of OSPW. Liquid-liquid extraction (LLE) was applied to avoid the matrix effect for the ESTD method. Reduced LLE efficiency accounted for the divergence of the ISTD and ESTD calibrated results for oxidized NAs. Principle component analysis results of O2 and O4 species could be employed for differentiation of water types, while classical NAs with C13-15 and Z (-4)-(-6) and aromatic O2-NAs with C16-18 and Z (-14)-(-16) could be measured as marker compounds to characterize water sources and potential temporal variations of samples, respectively. FTICR-MS results revealed that compositions of NA species varied greatly among OSPW, PLCA, and OSBA, because of NA transfer and transformation processes. This work contributed to the understanding of the concentration and composition of NAs in various types of water, and provided a useful combination of analytical and statistical tools for monitoring studies, in support of future safe discharge of treated OSPW.
