Abstract
Fibroblast growth factor receptor 2 ( FGFR2) in craniofacial bones mediates osteoprogenitor proliferation, differentiation, and apoptosis. The distortion of proper craniofacial bone growth may cause class II and class III skeletal malocclusion and result in compromised function and aesthetics. Here, we investigated the association between variations in FGFR2 and skeletal malocclusions. First, 895 subjects were included in a 2-stage case-control study with independent populations (stage 1: n = 138 class I, 111 class II, and 81 class III; stage 2: n = 279 class I, 187 class II, and 99 class III). Eight candidate single-nucleotide polymorphisms (SNPs) in FGFR2 were screened and validated. Five SNPs (rs2162540, rs2981578, rs1078806, rs11200014, and rs10736303) were found to be associated with skeletal malocclusions (all P < 0.05). That is, rs2162540 was significantly associated with skeletal class II malocclusion, while others were associated with skeletal class III malocclusion. Electrophoretic mobility shift assay and chromatin immunoprecipitation analysis showed that the common genotypes of rs2981578 and rs10736303 contained the binding sites of RUNX2 and SMAD4. Compared with the common genotypes, the minor genotypes at these 2 SNPs decreased the binding affinity and enhancer effect of RUNX2 and SMAD4, as well the levels of FGFR2 expression. In addition, FGFR2 expression contributed positively to osteogenic differentiation in vitro. Thus, we identified FGFR2 as a skeletal malocclusion risk gene, and FGFR2 polymorphisms regulated its transcriptional expression and then osteogenic differentiation.

Abstract
BACKGROUND Limited studies have explored the association between gaseous pollutant exposures and male reproductive outcomes, and findings remained inconsistent. OBJECTIVES To evaluate the potential association between gaseous pollutants and semen quality within different exposure windows. MATERIALS AND METHODS: We adopted semen quality data of 1852 subjects who attended the Reproductive Medicine Center of Renmin Hospital at Wuhan University during January 1st, 2013, to August 3rd, 2015. A generalized linear model was employed to assess the relationship between each exposure variable and sperm parameters in different exposure windows. RESULTS SO2 exposure with lag 0-90 days was significantly associated with decreased sperm concentration (β: -1.362; 95% CI: -1.844, -0.879), sperm count (β: -2.979; 95% CI: -4.267, -1.691), and PR (β: -0.551; 95% CI: -0.710, -0.393). Similar trends were observed for SO2 exposure with three other key periods (lag 0-9, 10-14, and 70-90 days). NO2 exposure with lag 0-90 days was also associated with decreased sperm concentration (β: -0.517; 95% CI: -1.006, -0.027), sperm count (β: -1.914; 95% CI: -3.214, -0.615), and PR (β: -0.264; 95% CI: -0.425, -0.102). No relationship between gaseous pollutant exposure and ejaculate volume was observed in any exposure window. DISCUSSION AND CONCLUSION Our study indicated a strong adverse effect of gaseous pollutants on semen quality outcomes during the sperm development. Gaseous pollution exposure appeared to be more detrimental in the initial phase of spermatogenesis.

Abstract
Different from most of the previous studies using light or photons, we use highly charged ions as projectiles to activate proton migration in the smallest saturated and unsaturated hydrocarbon molecules, i.e., CH4 and C2H2. The H3 + formation channel (H3 + + CH+) and isomerization channel (C+ + CH2 +), serving as indicators of proton migration, are observed in the fragmentation of CH4 and C2H2 dications. Corresponding kinematical information, i.e., kinetic energy release, is for the first time obtained in the collisions with highly charged ions. In particular, for the C+ + CH2 + channel, a new pathway is identified, which is tentatively attributed to the isomerization on high-lying states of acetylene dication. The kinetic energy release spectra for other two-body breakup channels are also determined and precursor dication states could thus be identified.

Abstract
The aim of present study was to investigate the effect of different times (5 min (UCPP-5), 10 min (UCPP-10), 20 min (UCPP-20), and 30 min (UCPP-30)) of ultrasound treatment on physicochemical, thermal, and antioxidant properties of chicken plasma protein (CPP). UCPP-20 had the highest fluorescence intensity and the lowest particle size. However, no major changes in the subunit compositions and the secondary structure of UCPPs were presented in SDS-PAGE and circular dichroism. The surface hydrophobicity and sulfhydryl content of UCPPs increased significantly (P < 0.05) as compared to those of CPP. With the increasing time of ultrasound treatment, there were more and deeper holes on the protein surfaces. Furthermore, protein modification by ultrasound could improve the thermal properties of UCPPs. Additionally, UCPPs showed a significant increase in antioxidant properties over CPP, especially UCPP-20. These observations indicated that ultrasound treatment was necessary for modification of CPP to meet the requirements for food processing.

Abstract
How insects promote crop pollination remains poorly understood in terms of the contribution of functional trait differences between species. We used meta-analyses to test for correlations between community abundance, species richness and functional trait metrics with oilseed rape yield, a globally important crop. While overall abundance is consistently important in predicting yield, functional divergence between species traits also showed a positive correlation. This result supports the complementarity hypothesis that pollination function is maintained by non-overlapping trait distributions. In artificially constructed communities (mesocosms), species richness is positively correlated with yield, although this effect is not seen under field conditions. As traits of the dominant species do not predict yield above that attributed to the effect of abundance alone, we find no evidence in support of the mass ratio hypothesis. Management practices increasing not just pollinator abundance, but also functional divergence, could benefit oilseed rape agriculture.

Abstract
We theoretically study Ar8+-induced dissociation of C2H2 molecule at 1.2 MeV using the time-dependent density-functional theory non-adiabatically coupled to nuclear dynamics. We find that molecular dissociation depends strongly on the ionization at the initial stage and the collision configuration. A detailed analysis shows a correspondence between the charge state of [C2H2]q+ and the final fragments. A remarkable impact parameter effect provides deep insights of bond breakup and electronic transport. We analyze two typical sequential dissociation channels reported in experiments by tracking structural and electronic dynamics in real time. Our results provide better understanding of experiments. Moreover, the comparison between various exchange-correlation functionals reveals that electrons' correlation and self-interaction do not significantly impact the initial ionization and fragment distribution in the present study.

Abstract
ABSTRACT In this study, neem leaves were successively extracted with petroleum ether, 95% ethanol and water and the insecticidal activities of these extracts against Oxya chinensis larvae were measured. The results showed that 95% ethanol extract gave the highest extraction yield and insecticidal activity, and it was further extracted with five different solvents. The petroleum ether extract from the 95% ethanol extract possessed the highest insecticidal activity with median lethal concentration values ranging from 14.93 to 55.66mg/mL. The gas chromatography-mass spectrometer analysis showed that the petroleum ether extract mainly composed of alkanes, olefin, esters and amide. The pathological examination revealed that the prominent lesions, including reduced regenerative cells in midgut and swelled and degenerated cylindrical cells, were observed in the 5th instar Oxya chinensis after treatment. The ultrastructural features showed that the cylindrical cells, microvilli and mitochondria were seriously damaged. These results suggested that the petroleum ether extract from neem leaves had potent insecticidal activity and could be a candidate insecticide.

Abstract
Three-dimensional skin equivalents are increasingly gaining acceptance as non-animal based experimental models of human skin. They are particularly suited to studying differences in physical and compositional properties of normal and diseased skin and their impact on the skin's barrier function. Typically, a culture protocol yielding a model of normal skin is modified to create a model simulating a pathology. Skin layer thicknesses and lipid/protein contents are compared using methods that are invasive, precluding further experiments on the same replicates, and which may be prone to artefacts. We show here that confocal Raman spectroscopy (CRS) is a valuable method for non-invasive discrimination of skin equivalents grown under different culture conditions. Using 3D full-thickness skin equivalents developed in-house, we measure significant differences in stratum corneum and viable epidermis apparent thicknesses resulting from a 7-day difference in the cultures' air-lift phase and from supplementation of the culture medium with interleukin 4. Furthermore, stratum corneum thicknesses obtained by CRS are up to 2.6-fold higher than values measured from histological photomicrographs. Regarding composition, CRS reveals the differential effects of the culture protocol modifications on ceramide, cholesterol and protein composition as a function of depth in the stratum corneum.

Abstract
Objective:To assess the clinical significance of nasal nitric oxide(NNO) levels in children with sleep disordered breathing(SDB).Method:Thirty children with SDB and twenty healthy children were enrolled. The NNO levels were measured non-invasively using a NIOX MINO system. SPSS statistics 20.0 software was used to analyze the data. Result:Compared to healthy children,NNO level was significant higher in children with SDB(Z=-2.215,P<0.05) .Correlation analysis showed that SDB children's NNO level was directly correlated with AHI(r=0.429,P<0.05),and it was inversely correlated with nadir SaO2(r=-0.482,P<0.01).But NNO level was not significantly correlated with other polysomnographic parameters. Conclusion:Our data suggested that NNO levels might be useful for evaluating the disease severity in SDB children.

Abstract
In this paper, a logistic-function-based nonlinear companding transform (LNCT) is proposed to reduce the peak-to-average power ratio of asymmetrical hybrid optical orthogonal frequency division multiplexing (AHO-OFDM) signals in visible light communications (VLC). First, the positive and negative amplitudes of the bipolar AHO-OFDM signal are divided into two groups as the positive and nonnegative groups. Then, a peak detection is employed frame-by-frame to locate the group where the maximum peak occurs. Finally, the piecewise companding transform consisting of the nonlinear logistic function and a linear function is performed on the amplitude groups with and without the maximum peak, respectively. The simulation results show that the proposed LNCT scheme outperforms the classical linear nonsymmetrical transform method in terms of the complementary cumulative distribution function with a competing bit error rate performance, thus demonstrating its application potential in AHO-OFDM-based VLC systems.

Abstract
PURPOSE To cross-culturally adapt and validate the International Knee Documentation Committee Subjective Knee Form to Simplified Chinese (SC-IKDC-SKF). METHODS The original version was translated and cross-culturally adapted into Simplified Chinese according to standard guidelines. A total of 103 patients enrolled in our research. Each participant was asked to complete three instruments including the SC-IKDC-SKF, the Lysholm knee score, and the Short Form-36 (SF-36). Each participant was asked to complete the SC-IKDC-SKF twice with an interval of 7 days. A portion of the participants (n = 51) finished the SC-IKDC-SKF a third time with an interval of 12 months after arthroscopic treatment. Psychometric assessments included internal consistency, test-retest reliability, content and construct validity, and responsiveness. RESULTS Strong internal consistency was proved with Cronbach's α = 0.92. The intraclass correlation coefficient reached 0.94, indicating high test-retest reliability. No ceiling or floor effect was observed. Compared with the Lysholm knee score and the subscales of SF-36, good convergent and divergent validity of the SC-IKDC-SKF were demonstrated. The standard response mean was 2.39 and the effect size was 1.33, indicating high responsiveness. CONCLUSIONS The SC-IKDC-SKF was demonstrated to be a reliable, valid and responsive instrument for evaluating knee functions and symptoms of patients with knee pathology in mainland China.

Abstract
Objective: To investigate the status and prognostic significance of TERT and IDH1/2 genes mutations in diffusely infiltrating gliomas. Methods: Hot spot mutations of TERT and IDH1/2 genes were detected by DNA sequencing in 236 cases of gliomas at West China Hospital from 2012 to 2016, including pilocytic astrocytoma (WHO grade Ⅰ, 16 cases), diffuse astrocytoma and oligodendroglioma (WHO grade Ⅱ, 89 cases), anaplastic astrocytoma and oligodendroglioma (WHO grade Ⅲ, 72 cases) and glioblastoma (WHO grade Ⅳ, 59 cases). The prognostic significance of TERT and IDH1/2 hot spot mutations was evaluated. Results: No IDH or TERT mutations were detected in pilocytic gliomas. TERT promoter mutation frequency was higher in patients aged ≥40 years(60.8%, 93/153) than in patients aged <40 years (32.8%, 22/67; P<0.01). TERT promoter mutation rate was also significantly higher in oligodendroglioma (87.5% , 56/64) than that in astrocytoma(37.8%, 59/156; P<0.01). Young age (<40 years), oligodendroglioma and IDH1 mutation were favorable prognostic factors for diffusely infiltrating astrocytic and oligodendroglial tumors. TERT mutation alone was not of prognostic significance. Diffusely infiltrating astrocytic and oligodendroglial tumors were divided into four molecular subtypes according to TERT and IDH1 mutation status: IDH(+ )/TERT(+ ), IDH(+ )/TERT(-), IDH(-)/TERT(-) and IDH(-)/TERT(+ ). There was significant prognostic difference among the 4 subtypes. Conclusions: Combined IDH and TERT gene mutation analysis may be useful for prognostic subgrouping. Notably, IDH1 wild-type cases can be further subdivided into TERT(+ ) or (-) subgroups with significant prognostic difference.

Abstract
BACKGROUND Macrophages undergo polarization or activation in response to environmental stimuli, an essential process for proper immune response. Meanwhile, excessive activation of macrophages causes autoimmune diseases. It is therefore crucial to prevent over-activation of macrophage in order to maintain the proper immune response. Arginase 1 (Arg-1) plays a critical role in coordinating the immune response by regulating availability of arginine. OBJECTIVE To understand the mechanism of Arg-1 regulation. METHODS Real-time PCR and Western Blot analysis were utilized to examine the Arg-1 levels expressed from the VEGFR1-deleted and VEGFR1-TK-deficient bone marrowderived macrophages (BMDMs). RESULTS The VEGFR1-mediated signaling suppressed IL-4-induced Arg-1 expression. Deletion of VEGFR1 resulted in elevated Arg-1 expression and the tyrosine kinase domain of VEGFR1 was required for the suppression. Each of three ligands of VEGFR1, VEGF-A, VEGF-B and PIGF, mediated the inhibition to the similar degree. CONCLUSION Our findings identified a novel function of the VEGFR1 signaling in avoiding over-expression of Arginase 1 potentially to maintain the proper innate immune response.

Abstract
BACKGROUND The purpose of this study was to determine the maximum tolerated dose (MTD, the dose of causing 10% respiratory depression) of intranasal sufentanil (SUF) and midazolam (MID) for sedation during gastroscopy by continual reassessment method (CRM). METHODS Patients (18-65 years old) scheduled for gastroscopy were recruited in this study. Subjects received intranasal SUF and MID for sedation. The dose of MID (5 mg) was fixed, while the dose of SUF was increased progressively (six incremental doses ranging from 0-0.60 μg/kg, n = 3 for each dose). The first cohort received a conservative, predetermined dose of 5 mg MID and 0 μg/kg SUF, subsequent cohorts received doses of SUF that were determined by the responses of all previous patients using Bayesian-based software. The dose allocated to the next cohort is the one with an updated posterior response probability closest to 10%. RESULTS Thirty Chinese patients scheduled for gastroscopy were included. Probability of respiratory depression at each dose was as follows: 5 mg MID + 0 μg/kg SUF, 0.4%; 5 mg MID + 0.1 μg/kg SUF, 0.8%; 5 mg MID + 0.2 μg/kg SUF, 1.8%; 5 mg MID + 0.3 μg/kg SUF, 3.7%; 5 mg MID + 0.4 μg/kg SUF, 9.9%; 5 mg MID + 0.5 μg/kg SUF, 17.8%; 5 mg MID + 0.6 μg/kg SUF, 36.0%. CONCLUSION The MTD of intranasal MID and SUF for sedation during gastroscopy causing 10% respiratory depression is 5 mg MID + 0.4 μg/kg SUF, based on CRM.

Abstract
OBJECTIVE Acute lymphocytic leukemia (ALL) is a multi-factorial blood disease with unknown pathogenesis. Histone H3K4 methylation was significantly reduced in ALL patients, whereas jumonji AT-rich interactive domain 1B (JARID1B) was the specific demethylase of H3K4me. This study explores the expression level of JARID1B in ALL patients and down-regulated JARID1B expression in ALL cells to explore the function of JARID1B in ALL. PATIENTS AND METHODS JARID1B mRNA expression level in ALL patients was detected by Real-time PCR. The peripheral blood mononuclear cells from healthy volunteers were selected as control. JARID1B shRNA was transfected with MOLT-4 cells and BALL-1 cells. JARID1B protein expression and H3K4me2 and H3K4me3 levels were detected by Western blot assay. Cell proliferation was assessed by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. Cell apoptosis and cell cycle were determined by flow cytometry. Bcl-2, Bax, Procaspase 3, and cyclin P21 expressions were evaluated by Western blot assay. RESULTS JARID1B mRNA expression in primary bone marrow cells from ALL patients was significantly higher than that of healthy volunteers (p<0.05). The levels of histone H3K4me3 and H3K4me2 were up-regulated after JARID1B shRNA transfection. JARID1B shRNA significantly inhibited the proliferation of MOLT-4 and BALL-1 cells, induced apoptosis, and blocked cell cycle in G0/G1 phase compared with the control group (p<0.05). CONCLUSIONS JARID1B is highly expressed in ALL. Down-regulating its expression inhibited leukemia cell proliferation, promoted apoptosis, and blocked cell cycle in G0/G1 phase through histone H3K4 methylation. JARID1B is an oncogene in ALL.
