Abstract
We experimentally report the generation of wavelength-tunable blueshifting soliton in the visible spectral region through a gas-filled single-ring photonic crystal fiber (SR-PCF). In particular, in a He-filled SR-PCF, we observed a sharp narrow-band spectral peak at the first resonant spectral region of the SR-PCF, which results from phase-matched nonlinear processes. To the best of our knowledge, this is the first time investigating the influence of the core-cladding resonance on the blueshifting soliton. In addition, when Ar gas was filled into the SR-PCF, some interference fringes on the blueshifting soliton were observed at high pulse-energy levels due to plasma-induced pulse fission. These two experimental observations are confirmed by numerical simulations. Furthermore, through properly adjusting input pulse energy, we found that the blueshifting soliton can obtain a high conversion efficiency (∼84%) and its wavelength can be tuned over hundreds of nanometers (∼240 nm).

Abstract
OBJECTIVES To develop a method to screen and quantify 10 common herbicides (paraquat, diquat, glyphosate, glufosinate, cyanazine, atrazine, metazachlor, acetochlor, chlorsulfuron, and metsulfuron) in blood. METHODS With acetonitrile-water solution [V(acetonitrile)∶V(water)=3∶1] as protein precipitant, 10 common herbicides in blood were detected using ultra-high performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS). RESULTS All the 10 herbicides had good linearity in their linear range (coefficient of determination R2≥0.993), with the recovery rates 67.4%-111.9%, the relative standard deviations 1.5%-10.8%, the accuracies 85.1%-106.1%, intra-day precisions 2.7%-13.5%, and inter-day precisions 3.3%-13.3%. CONCLUSIONS This method is easy to operate with high recovery rates. It enables rapid and accurate qualitative screening and quantitative analysis of various herbicides in blood simultaneously.

Abstract
Objective: To understand the cognition and attitudes of men who have sex with men (MSM) towards HIV testing and explore in-depth reasons preventing them from testing. Methods: The function of "opinion" in Blued, a gay geo-social networking application (GSN), was adopted to collect qualitative data of ideas and attitudes towards HIV testing of the users between December 2017 and January 2018. The data was analyzed based on grounded theory approach. Results: 28 269 Blued users participated in the activity and 1 977 posted comments. Four key themes were identified, i.e. no/low risk of contracting HIV, stigmatization of HIV testing, long-term relationship and conventional impediments of HIV testing. Conclusion: The cognition and attitudes of the target population derived from the analysis of "opinion" function in Blued, such as the stigmatization of the behavior of HIV testing influencing the attitude of HIV testing, could help researchers build a more accurate detection and promotion strategy instead of a very general intervention on the public.

Abstract
Our study aims to evaluate the endothelial cell-podocyte crosstalk in proliferative lupus nephritis (LN). The semi-quantification scores of glomerular endothelial cell injury and the foot process width (FPW) were processed in 110 proliferative LN patients. Podocytes were stimulated with LN-derived IgG. Glomerular endothelial cells were treated with podocyte-conditioned medium (PCM), and then podocytes were incubated with endothelial cell-conditioned medium (ECM). The levels of vascular endothelial growth factor-A (VEGF-A) in PCM and endothelin-1 in ECM were analyzed, and the injury of podocyte and glomerular endothelial cells were further evaluated. The pathological score of glomerular endothelial cell injury was correlated with FPW in LN complicated with thrombotic microangiopathy. In vitro study showed the following: 1. Stimulation of podocytes by IgG from LN led to decline in the expression of nephrin with cytoskeleton rearrangement, and reduction of VEGF-A levels. 2. Exposure of glomerular endothelial cells to PCM incubated with LN-derived IgG (PCM-LN) induced more endothelin-1 secretion and disruption of intercellular tight junction. 3. Exposure of podocytes to ECM stimulated with PCM-LN could induce cytoskeleton redistribution with decrease of nephrin. In conclusion, the pathological glomerular endothelial cell lesions were associated with FPW and the VEGF-endothelin-1 system might play a critical role in the endothelial cell-podocyte crosstalk in LN.

Abstract
Improvement in growth and fatness traits are the main objectives in pig all breeding programs. Tenth rib backfat thickness (10RIBBFT) and days to 100 kg (D100), which are good predictors of carcass lean content and growth rate, respectively, are economically important traits and also main breeding target traits in pigs. To investigate the genetic mechanisms of 10RIBBFT and D100 of pigs, we sampled 1,137 and 888 pigs from 2 Yorkshire populations of American and British origin, respectively, and conducted genome-wide association study (GWAS) through combined analysis and meta-analysis, to identify SNPs associated with 10RIBBFT and D100. A total of 11 and 7 significant SNPs were identified by combined analysis for 10RIBBFT and D100, respectively. And in meta-analysis, 8 and 7 significant SNPs were identified for 10RIBBFT and D100, respectively. Among them, 6 and 5 common significant SNPs in two analysis results were, respectively, identified associated with 10RIBBFT and D100, and correspondingly explained 2.09% and 0.52% of the additive genetic variance of 10RIBBFT and D100. Further bioinformatics analysis revealed 10 genes harboring or close to these common significant SNPs, 5 for 10RIBBFT and 5 for D100. In particular, Gene Ontology analysis highlighted 6 genes, PCK1, ANGPTL3, EEF1A2, TNFAIP8L3, PITX2, and PLA2G12, as promising candidate genes relevant with backfat thickness and growth. PCK1, ANGPTL3, EEF1A2, and TNFAIP8L3 could influence backfat thickness through phospholipid transport, regulation of lipid metabolic process through the glycerophospholipid biosynthesis and metabolism pathway, the metabolism of lipids and lipoproteins pathway. PITX2 has a crucial role in skeletal muscle tissue development and animal organ morphogenesis, and PLA2G12A plays a role in the lipid catabolic and phospholipid catabolic processes, which both are involved in the body weight pathway. All these candidate genes could directly or indirectly influence fat production and growth in Yorkshire pigs. Our findings provide novel insights into the genetic basis of growth and fatness traits in pigs. The candidate genes for D100 and 10RIBBFT are worthy of further investigation.

Abstract
Objective This study aimed to evaluate the clinical value of urinary biomarkers including kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and monocyte chemoattractant protein-1 (MCP-1) in lupus nephritis. Methods A total of 109 biopsy-proven lupus nephritis patients were included and 50 healthy individuals were used as normal controls. Urinary KIM-1, NGAL, and MCP-1 levels were measured by ELISA and their correlations with clinical and histological features were assessed. Receiver operating characteristic curves were performed and the Cox regression model was applied to identify prognostic factors associated with renal outcomes. Results Active lupus nephritis patients exhibited elevated urinary levels of KIM-1, NGAL, and MCP-1 compared with lupus nephritis patients in remission ( P < 0.001) and normal controls ( P < 0.001). The urinary KIM-1 level was correlated with pathological tubular atrophy ( r = 0.208, P < 0.05) and increased significantly in the presence of interstitial inflammatory lesions ( P = 0.031). Urinary KIM-1, NGAL, and MCP-1 levels were higher in patients with active tubulointerstitial lesions than in those with only chronic lesions ( P = 0.015, P = 0.230, and P = 0.086, respectively). A combination of KIM-1, NGAL, and MCP-1 was a good indicator for diagnosing active tubulointerstitial lesions (area under the curve: 0.796). The combination of KIM-1 and NGAL was identified as an independent risk factor for renal outcomes (hazard ratio = 7.491, P < 0.05). Conclusion Urinary KIM-1, NGAL, and MCP-1 levels were associated with kidney injury indices in lupus nephritis. The combination of the three biomarkers showed increased power in predicting tubulointerstitial lesions and renal outcomes.

Abstract
Objective: To explore the effect of BoTN-A on pathological characteristics of calf (GM) and motor function of ankle dorsiflexors in SCI model rats. Methods: Thirty-six SD male rats (weight 260-280 g) were randomly allocated into normal control group and 12w-control group, NS-injection group and BT-injection group in this study.NS/BT-injection groups were divided into two subgroups separately (2w-NS, 2w-BT, 8w-NS, 8w-BT). No injection was applied in normal control group or 12w-control group.Saline/BoTN-A was injected in right GM in NS/BT-injection group at two different time points(2w, 8w). GM and Sol on right side of rats would be forwarded for pathologicalexaminations, such as muscle weight, myosin heavy chain (MyHC) electrophoretic analysisat the 12th week. Results: Compared with the other three groups, the muscle weights of GM and Sol in the BT-injection group significantly decreased.MyHC type ratioof GM and Sol on the right side in the BT-injection group also significantlychanged.According to subgroup comparisons, MyHC type ratio of GM and Sol on the injectedside in the 2w-BT subgroup was significant different from that of the 8w-BT subgroup.MyHC type ratios of GM on the non-injected side in the BT injection group also changed more than normal control group.The change of MyHC type ratio of non-injected GM was significantly higher in the 2 week-BT subgroup than that in the 8-week subgroup. Conclusions: BoNT-A intervention resulted in pathological changes not only in the injected GM in SCI rats, but also in non-injected GM and non-injected Sol.The effects of earlier (2 weeks) BoTN-A intervention on pathologic characteristicsof GM and Sol were larger than that of later intervention.

Abstract
Objective: To evaluate the effect of human placental extracts (HPE) on the protection from acute liver injury (ALI) induced by D-GalN and analyze the components of HPE. Methods: (1)Fourty male mice were randomly divided into five groups (Blank, Model, MgIG, HPE and HPE+ MgIG) for the ALI model and treatments.The serum alanine aminotransferase (ALT) and aspartate transaminase (AST) were determined by biochemical assays.Nitric monoxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD), total antioxidant capacity (T-AOC) in serum and hepatic tissue were detected by assay kits.The extent of liver damage was evaluated by histological examination.(2)Relative molecular mass of HPE was determined by SDS-PAGE.(3) Component identification was performed by using LCMS-TOF.(4)Selected functional molecules in HPE were detected by protein array. Results: (1) A lower level of NO and MDA and a higher SOD and T-AOC were observed in rats treated with HPE compared to the non-treated rats in an acute liver failure disease model.(2) The size of HPE was about 1 200-4 600 by electrophores.(3) 7 peaks of HPE were identified, including uracil, hypoxanthine, tyrosine, phenylalanine, tryptophan, xanthine and thymine.(4) Comparable high concentrations of TGF-β, IGF-1, IL-9, IL-29 and TNF-α of HPE were revealed by protein array. Conclusions: (1) HPE protects rat from liver damage induced by D-GalN. (2) HPE contains Uracil, hypoxanthine, xanthine, thymine, and functional proteins as TGF-β, IGF-1, IL-9, IL-29 and TNF-α.

Abstract
The Moderate Resolution Imaging Spectroradiometer (MODIS) C6 L3 and the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim reanalysis data from 2003 to 2016 are employed to study aerosol-cloud correlations over three industrial regions and their adjacent oceans, as well as explore the impact of meteorological conditions on the correlations. The analysis focusing on liquid and single-layer clouds indicates an opposite aerosol-cloud correlation between land and ocean; namely, cloud effective radius is positively correlated with aerosol index over industrial regions (positive slopes), but negatively correlated over their adjacent oceans (negative slopes), for a quasi-constant liquid water path. The positive slopes are relatively large under low lower-tropospheric stability (LTS; weakly stable condition), but much weaker or even become negative under high LTS (stable conditions) and high liquid water path. The occurrence frequency of cloud top height (CTH) and LTS suggests that positive correlations are more likely corresponding to relatively high CTH and low LTS, while negative to low CTH and high LTS.
