Abstract
A meta-analysis was performed to assess the benefits and safety profile of approved immune checkpoint inhibitors in hepatocellular carcinoma patients. Eligible studies were searched from Cochrane, Embase, and PubMed databases based on a well-established strategy. Following the exclusion of ineligible studies, 12 studies were included in this meta-analysis. Compared with control group, immune checkpoint inhibitors were associated with improved ORR (OR 3.03, 95% CI 2.26-4.05, P < 0.00001), SD (OR 0.77, 95% CI 0.62-0.95, P = 0.02), OS (HR 0.75, 95% CI 0.68-0.83, P < 0.00001), and PFS (HR 0.74, 95% CI 0.63-0.87, P < 0.0003). However, no significant differences were observed in DCR (OR 1.33, 95% CI 0.97-1.81, P = 0.07), PD (OR 0.90, 95% CI 0.67-1.21, P = 0.48), and all caused any-grade adverse events (OR 1.22, 95% CI 0.62-2.39, P = 0. 57), all caused ≥ grade 3 adverse events (OR 1.10, 95% CI 0.97-1.25, P = 0.14), treatment-related any-grade adverse events (OR 1.13, 95% CI 0.55-2.32, P = 0.73), and treatment-related ≥ grade 3 events (OR 0.82, 95% CI 0.34-1.97, P = 0.65) between the two groups. After subgroup analysis conducted, patients in the immune checkpoint inhibitor group compared with targeted drug group showed significant improvements in OS (HR 0.74, 95% CI 0.66-0.84, P < 0.00001) and PFS (HR 0.75, 95% CI 0.61-0.91, P = 0.004). Immune checkpoint inhibitors have demonstrated peculiar benefits in the treatment of HCC with an acceptable safety profile. Compared to targeted drugs, immune checkpoint inhibitors still offer advantages in the treatment of hepatocellular carcinoma. However, there is still considerable room for further improvement.

Abstract
In-situ chemical oxidation (ISCO) is a commonly used method for the remediation of environmental contaminants in groundwater systems. However, traditional ISCO methods are associated with several limitations, including safety and handling concerns, rebound of groundwater contaminants, and difficulty in reaching all areas of contamination. To overcome these limitations, novel Controlled-Release Biodegradable Polymer (CRBP) pellets containing the oxidant KMnO₄ were designed and tested. The CRBP pellets were encapsulated in Polyvinyl Acetate (CRBP-PVAc) and Polyethylene Oxide (CRBP-PEO) at different weight percentages, baking temperatures, and time. Their release efficiency was tested in water, soil, and water and soil mixture media. Results showed that CRBP-PVAc pellets with 60 % KMnO₄ and baked at 120 °C for 2 min had the highest release percentage and rate across different conditions tested. Natural organic matter was also found to be an important factor to consider for in-field applications due to its potential reducing effect with Mn O 4 - . Overall, the use of CRBP pellets offers an innovative and sustainable solution to remediate contaminated groundwater systems, with the potential to overcome traditional ISCO limitations. These findings suggest that CRBP pellets could provide sustained and controlled release of the oxidant, reducing the need for multiple injections and minimizing safety and handling concerns. This study represents an important step towards developing a new and effective approach for ISCO remediation.

Abstract
As a short-chain PFAS (per- and polyfluoroalkyl substance), GenX was produced in recent years to replace traditional long-chain PFASs, such as perfluorooctanoic acid (PFOA). However, GenX turns out to be more toxic than people originally thought, posing health risks as a persistent environmental pollutant. In this research, for the first time, we incorporated chlorella, a single-celled green freshwater microalga that grows worldwide, with polyacrylonitrile (PAN) in equal amounts in electrospun nanofibers and studied the capability of the electrospun PAN/Algae bicomponent nanofibrous membrane (ES(PAN/Algae)) to bind and remove GenX from water. The incorporation of algae demonstrated a synergistic effect and significantly improved the GenX removal efficiency of the nanofibrous membrane. The maximum GenX removal capacity reached 0.9 mmol/g at pH 6, which is significantly higher than that of most of the reported GenX adsorbents as well as activated carbon. The GenX removal mechanism was investigated and discussed by using water contact angle, zeta potential, FTIR, and XPS techniques. This research demonstrated the potential to make highly efficient adsorbent/filter materials from common and economic materials to practically remediate short-chain PFASs from various water bodies.

Abstract
After mating, female mosquitoes need a blood meal to promote the reproductive process. When mosquitoes bite infected people and animals, they become infected with germs such as viruses and parasites. Mosquitoes rely on many cues for host selection and localization, among which the trace chemical cues emitted by the host into the environment are considered to be the most important, and the sense of smell is the main way to perceive these trace chemical cues. However, the current understanding of the olfactory mechanism is not enough to meet the needs of mosquito control. Unlike previous studies that focused on the olfactory receptor recognition spectrum to reveal the olfactory mechanism of mosquito host localization. In this paper, based on the observation that mosquitoes with incomplete antennae still can locate the host and complete blood feeding in the laboratory, we proposed that there may be some protection or compensation mechanism in the 13 segments of antennae flagella, and only when the antennae are missing to a certain threshold will it affect the mosquito's ability to locate the host. Through rational-designed behavioral experiments, we found that the 6th and 7th flagellomeres on the Aedes albopictus antenna are important in the olfactory detection of host searching. This study preliminarily screened antennal segments important for host localization of Ae. albopictus, and provided a reference for subsequent cell biology and molecular biology studies on these segments. Meanwhile, the morphology and distribution of sensilla on each antenna flagellomere were also analyzed and discussed in this paper.

Abstract
This retrospective study aims to identify the single nucleotide polymorphisms (SNPs) of 5,10-methylenetetrahydrofolate reductase (MTHFR) (C677T, A1298C), methionine synthase reductase (MTRR) (A66G) and ethnic distribution characteristics in pregnant women, and to explore the risk correlation with folate metabolism. The demographic data of 8735 pregnant women aged 15 to 47 years were retrospectively analyzed, and peripheral blood samples were collected and tested. Reverse transcription-quantitative polymerase chain reaction was applied to determine the genotype and allele frequency of MTHFR C677T, A1298C and MTRR A66G in blood samples. Sperman correlation analysis, univariate and multivariate logistic regression analysis were used to verify the correlation between SNPs of MTHFR (C677T, A1298C), MTRR (A66G), different ethnic groups and the susceptibility and risk levels of folate metabolism. The relative risk of the SNPs was further determined by calculating the odds ratio (OR) at a 95% confidence interval (CI). The average age of 8735 pregnant women was 28.87 ± 4.20 years old. The evaluation of risk levels for folate metabolism was relative high, including 2296 cases with low risk, 3971 cases with medium risk, and 752 cases with high risk. Among the MTHFR C677T locus, the CC genotype had the highest frequency, MTHFR A1298C locus had the highest frequency of the AA genotype, and MTRR A66G locus had the highest frequency of the AA genotype. The frequency distribution of SNPs in different ethnic groups revealed that the frequency of CT genotype among the MTHFR C677T locus, AA genotype among the MTHFR A1298C locus and the MTRR A66G locus was the highest in Han, Buyi, Miao and Dong ethnic groups. The results of logistic regression analysis showed that the Han, Buyi, Miao and other ethnic groups (including Yi, Bai, Zhuang, Chuanqing) had the possibility of increasing the risk levels of folate metabolism. The CC genotype of MTHFR C677T (adjusted OR = 2.46, 95% CI: 2.14-2.84, P < .001) and the AG genotype of MTRR A66G (adjusted OR = 1.89, 95% CI: 1.61-2.22, P < .001) were significantly related to the risk levels of folate metabolism, which is an independent risk factor for the susceptibility of folate metabolism.

Abstract
1. Although PRL-PRLR signalling plays important roles in regulating avian reproduction, there is a paucity of information regarding the functional significance of PRLR in goose ovarian follicle development.2. The full-length 2,496 bp coding sequence of PRLR was obtained from Sichuan White goose (Anser cygnoides) for the first time and was seen to encode a polypeptide containing 831 amino acids. Goose PRLR shares similar sequence characteristics and conserved functional domains to other avian species and was phylogenetically clustered into the avian clade.3. The qPCR results suggested that the mRNA levels of PRLR significantly increased in primary follicles during weeks 3 to 4 of age and were higher in secondary- than in primordial follicles at week 5 post-hatching, which suggested that the PRLR-mediated signalling could be involved in regulation of early folliculogenesis.4. The PRLR mRNA was expressed at the highest levels in the prehierarchical 8-10 mm granulosa layers throughout goose ovarian follicle development, indicating a role for PRLR in the process of follicle selection.5. PRLR mRNA was differentially expressed in the three cohorts of in vitro cultured granulosa cells harvested from different sized goose ovarian follicles, which suggested that PRLR was involved in regulating granulosa cell functions depending on the stage of follicle development. These data provide novel insights into the role of PRLR during goose ovarian follicle development, although the underlying mechanisms await further investigations.

Abstract
The lunar nearside has been investigated by many uncrewed and crewed missions, but the farside of the Moon remains poorly known. Lunar farside exploration is challenging because maneuvering rovers with efficient locomotion in harsh extraterrestrial environment is necessary to explore geological characteristics of scientific interest. Chang'E-4 mission successfully targeted the Moon's farside and deployed a teleoperated rover (Yutu-2) to explore inside the Von Kármán crater, conveying rich information regarding regolith, craters, and rocks. Here, we report mobile exploration on the lunar farside with Yutu-2 over the initial 2 years. During its journey, Yutu-2 has experienced varying degrees of mild slip and skid, indicating that the terrain is relatively flat at large scales but scattered with local gentle slopes. Cloddy soil sticking on its wheels implies a greater cohesion of the lunar soil than encountered at other lunar landing sites. Further identification results indicate that the regolith resembles dry sand and sandy loam on Earth in bearing properties, demonstrating greater bearing strength than that identified during the Apollo missions. In sharp contrast to the sparsity of rocks along the traverse route, small fresh craters with unilateral moldable ejecta are abundant, and some of them contain high-reflectance materials at the bottom, suggestive of secondary impact events. These findings hint at notable differences in the surface geology between the lunar farside and nearside. Experience gained with Yutu-2 improves the understanding of the farside of the Moon, which, in return, may lead to locomotion with improved efficiency and larger range.

Abstract
As a short-chain PFAS, GenX has gained increasing attention in recent years as a hazardous and emerging contaminant in water bodies. However, there is only limited research outcome up to date to address GenX remediation from water. In this research, we investigated amidoxime surface-functionalized PAN nanofibrous material from electrospinning as adsorbent to remove GenX from water. The nanofibrous adsorbent from 10 min treatment of electrospun PAN nanofibrous material in hydroxylamine (ASFPAN10) realized 35% GenX removal from a 100 mg/L aqueous solution at pH = 4 and 0.24 g/L loading after a simple one-time filtration with a GenX removal capacity of ~0.6 mmol/g. The mechanism study indicated that the GenX adsorption on PAN nanofibrous adsorbent could be mainly ascribed to hydrophobic interaction and dipole-dipole interaction between CN and C-F while the GenX adsorption on ASFPAN10 nanofibrous adsorbent could be mainly attributed to coulomb force between positive-charged CN+(OH)-H from ASFPAN10 and negative-charged COO- from GenX. Compared to that of PAN, the more hydrophilic surface of ASFPAN10 facilitated water access to the nanofibrous adsorbent surface and also contributed to the higher GenX removal efficiency. For the first time, this research pointed out a direction to use common economic materials for effective remediation of short-chain PFAS from water bodies especially at relatively high PFAS centration.

Abstract
The present study hypothesized that fumaric acid and succinic acid may exhibit therapeutic effects on gestational hypertension. During pregnancy, estrogen upregulates ten-eleven translocation 1 (TET1) expression, which subsequently increases calcium-activated potassium channel subunit β1 (KCNMB1) expression. KCNMB1 is associated with hypertension. Fumaric acid and succinic acid are understood to inhibit TET. Therefore, the present study investigated whether fumaric acid and succinic acid exhibit therapeutic effects on gestational hypertension and whether these effects are mediated by TET1 and KCNMB1. Nω-Nitro-L-arginine methyl ester hydrochloride was injected into rats to establish a gestational hypertension model. Dimethyl fumarate (DMF) and succinic acid were administrated into rats to treat gestational hypertension. Rats were divided into five groups: i) Control; ii) model; iii) DMF; iv) succinic acid; and v) DMF + succinic acid. Blood pressure was monitored by a noninvasive meter and urinary protein was determined using a urinary protein kit. Placenta pathology was examined by hematoxylin-eosin staining. Compared with the control group, urinary protein and blood pressure in the model group increased significantly. The placental cells in the control group were arranged orderly. However, in the model group, decidual cellular edema of placenta and vacuolar degeneration were observed, and the intervascular membrane was markedly thicker with plenty of fibrin deposition. These results indicate successful establishment of a gestational hypertension model. However, compared with the model group, urinary protein, blood pressure, edema, vacuoles and fibrin deposition were markedly reduced in the DMF, succinic acid and DMF + succinic acid groups. mRNA and protein levels of TET1 and KCNMB1 in placenta were evaluated by immunohistochemical analysis, reverse transcription-quantitative polymerase chain reaction and western blotting. The TET1 and KCNMB1 levels in the model group were markedly increased compared with those in the control group. However, compared with the model group, the expression levels were markedly downregulated in the DMF, succinic acid and DMF + succinic acid groups. In conclusion, fumaric acid and succinic acid may treat gestational hypertension by downregulating the expression of KCNMB1 and TET1.

Abstract
OBJECTIVE The purpose of this study was to investigate GOLPH3 expression in nasopharyngeal carcinoma (NPC) and its influence on the metastatic ability of NPC cells; meanwhile, the underlying mechanism of GOLPH3 promoting the malignant progression of NPC was also explored. PATIENTS AND METHODS In this study, quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to examine the expression of GOLPH3 in 34 pairs of tumor tissue and paracancerous tissue specimens collected from NPC patients, and the interplay between GOLPH3 expression and clinical indicators was analyzed, as well as the prognosis of NPC patients. Meanwhile, GOLPH3 expression in NPC cell lines was further verified by qRT-PCR assay. Furthermore, GOLPH3 knockdown model was constructed in NPC cell lines, including SUNE2 and CNE. Then, cell counting kit-8 (CCK-8), transwell invasion, and cell wound healing assays were applied to analyze the effect of GOLPH3 on the biological function of NPC cells. In addition, an in-depth study of the relationship between GOLPH3 and E-cadherin was conducted. RESULTS QRT-PCR results indicated that the expression level of GOLPH3 in NPC was remarkably higher than that in adjacent tissues, and the difference was statistically significant. Compared with patients with low expression of GOLPH3, those with high expression of GOLPH3 had a higher incidence of lymph node metastasis. Compared with sh-NC group, the proliferation and invasive ability of NPC cells decreased remarkably after knockdown of GOLPH3. Subsequently, E-cadherin expression was found to be remarkably reduced and negatively correlated with GOLPH3 in NPC cell lines and tissues. Finally, the recovery experiment demonstrated that GOLPH3 might have a mutual regulatory relation with E-cadherin, both of which jointly affect the malignant progression of NPC. CONCLUSIONS GOLPH3 expression is remarkably associated with lymph node metastasis and poor prognosis of NPC patients; in addition, it may promote the proliferation and metastatic ability of NPC cells by regulating E-cadherin.

Abstract
Previous evidences have indicated that granulosa cells play a critical role in follicular growth. Hydrogen peroxide (H2O2)-induced oxidative stress has been associated with ovarian granulosa cell apoptosis and ovarian function. Recently, a study highlighted the protective role of morroniside against H2O2-induced damage. In this study, we aimed to investigate the effects of morroniside on H2O2-stimulated rat ovarian granulosa cells and its underlying molecular mechanisms. Our results showed that H2O2 treatment suppressed cell survival and increased apoptosis in rat granulosa cells, while treatment with morroniside markedly increased H2O2-induced granulosa cell survival in a dose-dependent manner (0, 10, 50 and 100 µM). Moreover, treatment with 50 µM morroniside impeded H2O2-induced cell apoptosis. An elevation in intracellular ROS, MDA, SOD, GSH-Px, and CAT level was observed in H2O2-induced granulosa cells; however, this effect was abrogated by morroniside treatment. Further studies suggested that administration of morroniside inhibited H2O2-induced granulosa cell apoptosis and caspase-3 activity. In addition, after morroniside treatment of H2O2-stimulated granulosa cells, autophagy-related protein (LC3-II/LC3-I ratio) and beclin-1 expression was decreased and p62 level was increased. Interestingly, we found that morroniside treatment activated the PI3K/AKT/mTOR pathway in H2O2-stimulated granulosa cells. Finally, we showed that treatment with PI3K and mTOR inhibitors reversed the protective effects of morroniside on H2O2-induced granulosa cells. Taken together, our data suggest that treatment with morroniside decreased apoptosis, autophagy, and oxidative stress in rat granulosa cells through the PI3K/AKT/mTOR pathway.

Abstract
OBJECTIVE To explore the repair of spinal cord injury (SCI) in rats by umbilical cord mesenchymal stem cells (UCMSCs) through the p38mitogen-activated protein kinase (MAPK) signaling pathway. MATERIALS AND METHODS A total of 45 healthy adult male Sprague-Dawley rats weighing 180-220 g and aged 6-8 weeks old were randomly divided into group A (SCI model + transplantation of UCMSCs, n=15), group B (sham operation), and group C (SCI model + injection of an equal dose of DMEM, n=15) using a random number table. The morphology of spinal cord tissues was observed via hematoxylin-eosin (HE) staining, and the protein expression of phosphorylated p38 (p-p38) in spinal cord tissues, the expression of glial fibrillary acidic protein (GFAP) in the injury region, and the spinal cord neuronal apoptosis were detected via Western blotting, immunofluorescence labeling and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, respectively. RESULTS In group B, there was no significant damage to the structure of spinal cord tissues. In group C, the spinal cord tissues had a disordered structure and significant fragmentation, the damage to grey matter was the greatest. Also, almost all of the grey matter was destroyed and dissolved, with a large number of scars and cavitation, and it was hard to distinguish the gray matter and white matter. In group A, the spinal cord tissues had a clear structure, there were smaller necrotic cavitation regions in the grey-white matter, and the number of cavitation significantly declined compared with that in group C. The results of immunofluorescence assay revealed that the expression of GFAP in spinal cord tissues was the lowest in group B, while it was remarkably decreased in group A compared with that in group C (p<0.05), suggesting that injecting UCMSCs via the caudal vein can prominently reduce the expression of GFAP in spinal cord tissues. Moreover, the spinal cord neuronal apoptosis rate was (4.21±0.19), (0.72±0.21) and (4.57±0.31), respectively, in group A, group B, and group C. It can be seen that the spinal cord neuronal apoptosis rate significantly declined in group A due to the treatment with UCMSCs. Also, the significant difference compared with that in group C, while it was significantly increased in group A compared with that in group B, but lower than group C (p<0.05). According to the results of Western blotting, the protein expression of p-p38 in spinal cord tissues was remarkably decreased in group B compared with that in group A and group C (p<0.05), while it was also markedly decreased in group A compared with that in group C (p<0.05), indicating that injecting UCMSCs via the caudal vein can significantly lower the protein expression of p-p38 in spinal cord tissues. CONCLUSIONS UCMSCs promote the recovery of neurological function, inhibit the p38 MAPK pathway activated after SCI, and reduce the spinal cord neuronal apoptosis in SCI rats.

Abstract
Background:Refractory gout manifests as recurrent flares, chronic arthritis and progressive tophaceous deposits. Febuxostat is a widely-used potent serum urate-lowering reagent, but some gout patients cannot achieve target serum uric acid (sUA) after they used this reagent.Objectives:To determine whether febuxostat-resistance should be a criterion for refractory gout, characteristics of gout patients who were resistance to febuxostat or allopurinol were compared.Methods:This study was performed from December 2015 to December 2019. Medical records of gout patients who met the 2015 gout classification criteria [1] and undertook febuxostat (febuxostat group) or allopurinol (allopurinol group) urate-lowing therapy (ULT) were assessed. Dose of ULT was adjusted till sUA was below 6 mg/dL and 5 mg/dL for patients with urate deposition. We screened gout patients who had contraindication or history of failure to normalize sUA for≥ 3 months of treatment with the maximum medically appropriate febuxostat (febuxostat-resistance) or allopurinol (allopurinol-resistance) dose as defined by physicians. Furthermore, these screened patients met the traditional criteria of refractory gout except therapeutic reaction [2].Demography and clinical characteristics were recorded. Features between febuxostat-resistance and allopurinol-resistance patients were compared.Results:(1) Of 683 gout patients who were included, 516 and 167 of them used febuxostat or allopurinol. (2) Age (41.92±11.58 vs. 42.26±9.41 years), Male gender (97.50% vs. 97.01%), duration of gout (5.78±4.74 vs. 5.05±4.72 years) and sUA (6.30±2.50 vs. 6.67±2.14 mg/dL) were similar between febuxostat group and allopurinol group (P>0.05). (3) Dose of febuxostat or allopurinol were 47.28mg/day and 178.24mg/day. (4) Sixteen patients were febuxostat-resistance, while 6 patients were allopurinol-resistance. Prevalence rates of treatment resistance were comparable between groups (3.10% vs. 3.59%,P>0.05). (5) Some parameters were different between resistance patients and non-resistance patients in both groups (Table 1,P<0.05). However, characteristics of febuxostat-resistance and allopurinol-resistance patients were similar (P>0.05).Table 1Characteristics of gout patients in febuxostat group and allopurinol groupParametersFebuxostat GroupAllopurinol GroupNon-resistance(n=500)Resistance(n=16)Non-resistance(n=161)Resistance(n=6)Age (year)41.93±11.6541.67±9.5842.22±13.3344.50±16.98Male Gender (%)97.40100.0096.89100.00BMI (kg/m2)25.44±3.4626.22±3.4725.86±3.9725.60±6.42Duration of gout (years)5.75±4.767.00±3.97*4.96±4.737.75±2.62*Flares in previous 18 months (times)1.31±0.443.67±0.70*1.13±0.243.25±0.50*Presence of Tophi (%)23.80100.00*14.90100.00*Presence of Complication (%)35.8100.00*31.06100.00*sUA (mg/dL)6.21±2.479.13±1.24*6.42±2.3210.15±3.55*SCr (μmol/L)100.67±15.03163.96±29.41*96.93±22.91133.75±31.60*ESR (mm/L)24.59±19.2842.83±21.13*27.49±24.1056.50±28.12*CRP (mg/L)18.92±18.5928.81±23.85*23.12±22.6332.28±23.64**P<0.05 compared with non-resistance patients in the same group.BMIbody mass index,sUAserum uric acid,SCrserum creatinine,ESRerythrocyte sedimentation rate,CRPC-reactive proteinConclusion:Febuxostat-resistance is a potential criterion for refractory gout, because febuxostat-resistance patients shares similar characteristics of patients with refractory gout.References:[1]Neogi T, Jansen TL, Dalbeth N, et al. 2015 Gout classification criteria: an American College of Rheumatology/European League Against Rheumatism collaborative initiative.

Abstract
OBJECTIVES The present study aimed to explore the effect of umbilical cord mesenchymal stem cells (UC-MSCs) on the modulation of T lymphocytes from system lupus erythematosus (SLE) patients and the possible mechanism. METHODS A total of 24 hospitalized SLE patients and 28 healthy individuals were enrolled. T lymphocytes were sorted using Miltenyi magnetic beads. After the addition of recombinant human interleukin (IL)-2 and CD3CD28 T-cell activator, cells were loaded onto six-well plates pre-inoculated or not with UC-MSCs for 1 week of culture. The supernatants were collected for testing inflammatory factors by enzyme-linked immunosorbent assay. Meanwhile, T lymphocytes were collected to assess the expression levels of genes, proteins in relation to SLE and miR-181a by polymerase chain reaction and Western blot. RESULTS Compared with T lymphocytes cultured alone, interferon-γ, IL-4, IL-6 and IL-10 levels were significantly decreased in T lymphocytes from SLE patients co-cultured with UC-MSCs. In addition, the gene and protein expression levels of TNF alpha, osteopontin and nuclear factor-kappa B in T lymphocytes were significantly decreased, while miR-181a expression was markedly elevated (p < 0.05 or 0.008). CONCLUSION UC-MSCs have showed certain immunomodulatory and inhibitory effects in vitro on T lymphocytes from SLE patients, which could potentially be a beneficial treatment of the disease. UC-MSCs may up-regulate miR-181a and down-regulate inflammation-related gene expression.

Abstract
The detoxification of municipal solid waste incinerator (MSWI) fly ash dioxins urgently requires an effective treatment technology. In this study, we adopted a single-mode microwave (MW)-based pyrolysis to treat MSWI fly ash under N2 atmosphere and further elucidated the main influencing factors, including the chemical inhibitor, for dioxin control. The results show that (1) the detoxification process was optimized with a mass ratio of fly ash to SiC of 1:9, 23.1% (wt%) urea addition and pyrolysis temperature of ˜ 480 °C; (2) the total polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) destruction efficiency and the bioassay-derived 2,3,7,8-TCDD toxic equivalent (Bio-TEQ) removal efficiency reached 98.5% and 97.9%, respectively, accompanied with ˜ 1.3% of the total amount of dioxin being submitted to exhaust gas; (3) the MW-based pyrolysis of urea (133˜300 °C) was favourable for the generation of hot spots as well as the PCDD/F rapid destruction in fly ash. In addition, the leaching toxicity of heavy metals was also partially reduced after MW pyrolysis reactions. To the best of our knowledge, this is the first report adopting a MW-based pyrolysis to eliminate dioxin in MSWI fly ash with the addition of urea, which is a promising alternative to current methods.

Abstract
With an increasing amount of industrial wastewater being discharged and the numerous chemicals existed in, methods to identify toxicants in such complex matrices are urgently needed for source control and quality management. In vivo toxicity to Daphnia magna was evaluated in the effluent of a wastewater treatment plant (WWTP). An extended suspect screening strategy was performed by bioassay-directed fractionation, accompanied with suspect screening of 228 suspect chemicals in toxic fractions based on their mass characteristics and chromatography characteristics. A toxicity evaluation of the original samples, organic components extracted by solid-phase extraction (SPE) and the filtered samples showed that organic compounds extracted by SPE were the main toxic components. Four of the 26 fractions of the organic extracts exhibited a toxic unit (TU) > 1.0, with hydrophobic organic compounds contributing most to the toxicity. Twenty-eight of the 228 suspects were identified in four toxic fractions, with 53.6% of the suspects elucidated by spectrum interpretation based on mass characteristics and 53.8% more false positive suspects removed based on chromatography characteristics. Finally, 6 pollutants, including imazalil, prometryn, propiconazole, tebuconazole, buprofezin and diazinon, were further confirmed and explained 48.79% of the observed toxicity. With 2.48 times more of the toxicity explained and 90% of the labor saved, the extended suspect screening strategy enabled more efficient and reliable identification compared to traditional quantitative analysis and non-target screening, especially for identification of characteristic toxicants in complex environmental matrices.

Abstract
Background: Total P16 methylation (P16M), including P16 hydroxymethylation (P16H) and true-P16M, correlates with malignant transformation of oral epithelial dysplasia (OED). Both true-P16M and P16H are early events in carcinogenesis. Aim: The aim of this study is to prospectively determine if discrimination of true-P16M from P16H similarly is necessary for prediction of cancer development from OEDs. Methods: Patients (n = 265) with mild or moderate OED were recruited into the double-blind 2-center cohort. Total-P16M and P16H were analyzed using the 115-bp MethyLight, TET-assistant bisulfite (TAB) methylation-specific PCR (MSP), and TAB-sequencing. Total-P16M-positive and P16H-negative samples were defined as true-P16M-positive. Progression of OEDs was monitored for a minimum 24 months follow-up period. Results: P16H was detected in 23 of 73 (31.5%) total-P16M-positive OEDs. Follow-up information was obtained from 247 patients with an ultimate compliance of 93.2%. OED-derived squamous cell carcinomas were observed in 13.0% (32/247) patients during the follow-up (median, 41.0 months). The cancer progression rate for total-P16M-positive patients was significantly increased when compared with total-P16M-negative patients (23.3% vs 8.6%; adjusted odds ratio = 2.67 [95% CI: 1.19-5.99]). However, the cancer progression rate was similar between P16H- and true-P16M-positive OEDs (26.1% [6/23] vs 22.0% [11/50]; odds ratio = 0.80 [95% CI: 0.22-2.92]). The progression-free survival was also similar for these patients. Conclusion: P16H and true-P16M are similar biomarkers for determining malignant potential of OEDs. Discrimination of P16H from true-P16M, at least in OED, may be not necessary in clinical applications.

Abstract
A tiered screening strategy based on extensive virtual fractionation and elucidation was developed to simplify identification of toxicants in complex environments. In tier1-virtual fractionation, multivariate analysis (MVA) was set up as an alternative of physical fractionation. In tier2-virtual structure elucidation, in-house quantitative structure-retention relationship (QSRR) models and toxicity simulation methods were developed to simplify nontarget identification. The efficiency of the tiered virtual strategy was tentatively verified by soil samples from a chemical park contaminated by antiandrogenic substances. Eight out of 18 sites were detected as antiandrogenic, while none of them exhibited androgenic agonist potencies. Sixty-seven peaks were selected for further identification by MVA, among which over 90% were verified in androgenic fractions in traditional effect-directed analysis (EDA). With 579 tentative structures generated by in silico fragmentation, 74% were elucidated by QSRR and 65% were elucidated by in silico toxicity prediction. All prior peaks were identified at different confidence levels with over 40% of the identified peaks above confidence level 2b, which has been increased over 40% with less than half of the time spent compared to traditional EDA. Such a combination of tiered virtual screening methods provides more efficient and rapid identifications of key toxicants at contaminated sites.

Abstract
This study evaluated the technical feasibility of packed-bed sulfidogenic bioreactors dosed with ferrous chloride for continuous wastewater treatment over a 450-day period. In phase I, the bioreactors were operated under different combinations of carbon, iron, and sulfate mass loads without sludge recycling to identify optimal treatment conditions. A COD/sulfate mass ratio of 2 and a Fe/S molar ratio of 1 yielded the best treatment performance with COD oxidation rate of 786 ± 82 mg/(L⋅d), which resulted in 84 ± 9% COD removal, 94 ± 6% sulfate reduction, and good iron retention (99 ± 1%) under favorable pH conditions (6.2-7.0). In phase II, the bioreactors were operated under this chemical load combination over a 62-day period, during which 7 events of sludge collection, oxidation, and recycling were performed. The collected sludge materials contained both inorganic and organic matter with FeS and FeS2 as the main inorganic constituents. In each event, the sludge materials were oxidized in an oxidizing basin before recycling to mix with the wastewater influent. Sludge recycling yielded enhanced COD removal (90 ± 6% vs. 75 ± 7%), and better effluent quality in terms of pH (6.8 ± 0.1 vs. 6.5 ± 0.2), iron (0.7 ± 0.5 vs. 1.9 ± 1.7 mg/L), and sulfide-S (0.3 ± 0.1 vs. 0.4 ± 0.1 mg/L) removal compared to the baseline operation without sludge recycling during phase II. This process exhibited treatment stability with reasonable variations, and fairly consistent sludge content over long periods of operation under a range of COD/sulfate and Fe/S ratios without sludge recycling. The bioreactors were found to absorb recycling-induced changes efficiently without causing elevated suspended solids in the effluents.

Abstract
In this study, we firstly develop the photo-Fenton-like system with millimetric sponge iron (s-Fe0), H2O2, visible light (vis, λ≥420nm) and rhodamine B (RhB), and present a comprehensive study concerning the mechanism. Thus, we investigate (1) the adsorption of RhB onto s-Fe0, (2) the photo-Fenton-like removal of RhB over iron oxides generated from the corrosion of s-Fe0, (3) the homogeneous photo-Fenton removal of RhB over Fe2+ or Fe3+, (4) the Fe3+-RhB complexes, and (5) the photo-Fenton-like removal of tetrabromobisphenol A (TBBPA). The results show that neither the adsorption process over s-Fe0 nor the photo-Fenton-like process over FeOOH, Fe3O4 and Fe2O3, achieved efficient removal of RhB. For comparison, in homogeneous photo-Fenton process, the presence of Fe3+ ions, rather than Fe2+ ions, effectively eliminated RhB. Furthermore, the UV-vis spectra showing new absorbance at∼285nm indicate the complexes of RhB and Fe3+ ions, adopting vis photons to form excited state and further eject one electron via ligand-to-metal charge-transfer to activate H2O2. Additionally, efficient TBBPA removal was obtained only in the presence of RhB. Accordingly, the s-Fe0- based photo-Fenton-like process assisted with dyestuff wastewater is promising for removing a series of persistent organic pollutants.

Abstract
The g-C3N4-coupling TiO2 photocatalysts with controllable particle size as well as the interface contact were prepared by a general nonaqueous sol-gel method. The structural and morphological features of g-C3N4/TiO2 were investigated through the X-ray diffraction, Fourier transformed infrared spectra, scanning electron microscopy and transmission electron microscopy, respectively. It is found the TiO2 nanoparticles with a size of 7.3 ± 1.6 nm are uniformly anchored on the surface of the g-C3N4 nanosheets in isolation. The photocatalytic properties of as-prepared g-C3N4/TiO2 were tested by degradation of Rhodamine B (RhB) under visible light, and an enhanced activity is observed. The mechanism of the enhanced activity was further investigated through N2 adsorption-desorption isotherms, UV-vis spectra, photoluminescence spectra, photoelectrochemical measurements, radical trapping experiments and X-ray photoelectron spectroscopy. Furthermore, the photocatalytic performances of obtained g-C3N4/TiO2 under sunlight were also evaluated in aspects of degradation efficiency and stability. The results indicate that the obtained g-C3N4/TiO2 is one promising photocatalyst for practical applications. The study of as-prepared g-C3N4/TiO2 also implies that the present method could be a general route of g-C3N4-coupling photocatalysts.

Abstract
Chronic inflammation (CI) is a risk factor for pancreatic cancer (PC) including the most common type, ductal adenocarcinoma (PDAC), but its role and the mechanisms involved are unclear. To investigate the role of CI in PC, we generated genetic mouse models with pancreatic specific CI in the presence or absence of TP53. Mice were engineered to express either cyclooxygenase-2 (COX-2) or IκB kinase-2 (IKK2), and TP53+/+ or TP53f/f specifically in adult pancreatic acinar cells by using a full-length pancreatic elastase promoter-driven Cre. Animals were followed for >80 weeks and pancreatic lesions were evaluated histologically and immunohistochemically. The presence of K-ras mutations was assessed by direct sequencing, locked nuclei acid (LNA)-based PCR, and immunohistochemistry. We observed that sustained COX-2/IKK2 expression caused histological abnormalities of pancreas, including increased immune cell infiltration, proliferation rate and DNA damage. A minority of animals with CI developed pre-neoplastic lesions, but cancer was not observed in any TP53+/+ animals within 84 weeks. In contrast, all animals with CI-lacking TP53 developed various subtypes of PC, including acinar cell carcinoma, ductal adenocarcinoma, sarcomatoid carcinoma and neuroendocrine tumors, and all died within 65 weeks. No evidence of K-ras mutations was observed. Variations in the activity of the Hippo, pERK and c-Myc pathways were found in the diverse cancer subtypes. In summary, chronic inflammation is extremely inefficient at inducing PC in the presence of TP53. However, in the absence of TP53, CI leads to the development of several rare K-ras-independent forms of PC, with infrequent PDAC. This may help explain the rarity of PDAC in persons with chronic inflammatory conditions.

Abstract
Parvalbumin (PV)-positive interneurons in the hippocampus play a critical role in animal memory, such as spatial working memory. However, how PV-positive interneurons in the subregions of the hippocampus affect animal behaviors remains poorly defined. Here, we achieved specific and reversible activation of PV-positive interneurons using designer receptors exclusively activated by designer drugs (DREADD) technology. Inducible DREADD expression was demonstrated in vitro in cultured neurons, in which co-transfection of the hM3D-Gq-mCherry vector with a Cre plasmid resulted in a cellular response to hM3Dq ligand clozapine-N-oxide (CNO) stimulation. In addition, the dentate gyrus (DG) of PV-Cre mice received bilateral injection of control lentivirus or lentivirus expressing double floxed hM3D-Gq-mCherry. Selective activation of PV-positive interneurons in the DG did not affect locomotor activity or depression-related behavior in mice. Interestingly, stimulation of PV-positive interneurons induced an anxiolytic effect. Activation of PVpositive interneurons appears to impair social interaction to novelty, but has no effect on social motivation. However, this defect is likely due to the anxiolytic effect as the exploratory behavior of mice expressing hM3DGq is significantly increased. Mice expressing hM3D-Gq did not affect novel object recognition. Activation of PV-positive interneurons in the DG maintains intact cued and contextual fear memory but facilitates fear extinction. Collectively, our results demonstrated that proper control of PV interneurons activity in the DG is critical for regulation of the anxiety, social interaction and fear extinction. These results improve our fundamental understanding of the physiological role of PV-positive interneurons in the hippocampus.

Abstract
The kinetics and microbial ecology in sulfidogenic bioreactors used in a novel two-stage process for co-treatment of acid mine drainage (AMD) and municipal wastewater (MWW) were investigated. Michaelis-Menten modeling of COD oxidation by sulfate reducing bacteria (SRB) (Vmax=0.33mgL(-1)min(-1), Km=4.3mgL(-1)) suggested that the Vmax can be reasonably achieved given the typical COD values in MWW and anticipated mixing with AMD. Non-competitive inhibition modeling (Ki=6.55mgL(-1)) indicated that excessive iron level should be avoided to limit its effects on SRB. The COD oxidation rate was positively correlated to COD/sulfate ratio and SRB population, as evidenced by dsrA gene copies. Phylogenetic analysis revealed diverse microbial communities dominated by sulfate reducing delta-proteobacteria. Microbial community and relative quantities of SRB showed significant differences under different COD/sulfate ratios (0.2, 1 and 2), and the highest dsrA gene concentration and most complex microbial diversity were observed under COD/sulfate ratio 2. Major species were associated with Desulfovirga, Desulfobulbus, Desulfovibrio, and Syntrophus sp. The reported COD kinetics, SRB abundances and the phylogenetic profile provide insights into the co-treatment process and help identify the parameters of concerns for such technology development.
