Abstract
Objective: To investigate the impact of changes in the posterior tibial slope (PTS) in Oxford unicompartmental knee arthroplasty (OUKA) on the mid-term clinical outcomes of postoperative patients. Methods: This study was a follow-up study. The data of 135 patients (150 knees) who underwent OUKA at the China-Japan Friendship Hospital from January 2012 to January 2013 were analyzed retrospectively. The patients were followed-up for at least ten years. According to the changes in PTS of the medial tibial plateau before and after surgery, patients were divided into three groups: group A (PTS decreased by more than 5°), group B (PTS changed by 5° or less), and group C (PTS increased by more than 5°). The Knee Society Clinical Score (KSS-C), Knee Society Functional Score (KSS-F), Oxford Knee Score (OKS), Forgotten Joint Score (FJS), and knee range of motion (ROM) among the three groups were compared at the last follow-up. Results: Prior to the final follow-up assessment, six patients expired, and an additional nine patients were lost to follow-up. A total of 120 patients (135 knees) were enrolled in this study (30 males and 90 females). The mean age was (66.29±8.62) years, and the follow-up time was (10.54±0.72) years. Group A consisted of 32 patients (34 knees), group B comprised 77 patients (90 knees), and group C included 11 patients (11 knees). One knee in group A suffered prosthesis loosening, and two knees in group C experienced postoperative bearing dislocation, one knee encountered bearing fragmentation. The incidence of postoperative complications differed significantly among the three groups (P<0.05). The preoperative OKS was (33.91±6.59) points, KSS-F was (43.46±8.99) points, KSS-C was (41.05±5.70) points and ROM was 115.23°±13.53°; after the surgery, they changed to (18.82±7.01) points, (81.51±7.34) points, (82.64±7.94) points, and 119.07°±8.62°, respectively, and all the differences were statistically significant (all P<0.001). In terms of postoperative outcomes, group A had an OKS of (21.44±8.46) points and a FJS of (63.83±11.40) points, group B had an OKS of (17.07±5.81) points and a FJS of (70.49±12.45) points, group C had an OKS of (25.09±5.07) points and a FJS score of (59.48±10.09) points; the differences among the three groups were all statistically significant (all P<0.05), but there were no significant differences in the postoperative KSS scores and ROM among the three groups (all P>0.05). Conclusions: After OUKA, better mid-term clinical outcomes are achieved when ΔPTS is<5°. Although the recommended central value for PTS in OUKA is 7° according to Oxford, it should be individualized, and it is recommended to consider the preoperative angle, with a change of less than 5° before and after surgery.

Abstract
Detecting and classifying defects on unpatterned wafers is a key part of wafer front-end inspection. Defect inspection schemes vary depending on the type and location of the defects. In this paper, the structure of the prototype is designed to meet the requirements of wafer surface and edge defect inspection. This prototype has four inspection channels: scattering, reflection, phase, and contour, with two working conditions: surface and edge inspection. The key structure of the prototype was simulated using Ansys. The simulation results show that the maximum deformation of the optical detection subsystem is 19.5 μm and the fundamental frequency of the prototype is 96.9 Hz; thus, these results meet the requirements of optical performance stability and structural design. The experimental results show that the prototype meets the requirements of the inspection sensitivity better than 200 nm equivalent PSL spherical defects.

Abstract
The modes of Pacific decadal-scale variability (PDV), traditionally defined as statistical patterns of variance, reflect to first order the ocean's integration (i.e., reddening) of atmospheric forcing that arises from both a shift and a change in strength of the climatological (time-mean) atmospheric circulation. While these patterns concisely describe PDV, they do not distinguish among the key dynamical processes driving the evolution of PDV anomalies, including atmospheric and ocean teleconnections and coupled feedbacks with similar spatial structures that operate on different timescales. In this review, we synthesize past analysis using an empirical dynamical model constructed from monthly ocean surface anomalies drawn from several reanalysis products, showing that the PDV modes of variance result from two fundamental low-frequency dynamical eigenmodes: the North Pacific-central Pacific (NP-CP) and Kuroshio-Oyashio Extension (KOE) modes. Both eigenmodes highlight how two-way tropical-extratropical teleconnection dynamics are the primary mechanisms energizing and synchronizing the basin-scale footprint of PDV. While the NP-CP mode captures interannual- to decadal-scale variability, the KOE mode is linked to the basin-scale expression of PDV on decadal to multidecadal timescales, including contributions from the South Pacific.

Abstract
BACKGROUND AND AIMS Several studies have reported that variants in CYP2R1 have been linked with an increased risk of hypertension. However, the interaction between CYP2R1 variants and environmental factors on the susceptibility of hypertension remained unclear. Therefore, this study evaluated the influence of CYP2R1 polymorphisms on hypertension susceptibility, and explored the interaction effect of CYP2R1 variations and obesity on the disease. METHODS AND RESULTS We included 766 incident hypertension cases matched with non-hypertension controls in a 1:1 ratio by sex, age (within 3 years). Two loci in CYP2R1 gene (rs10766197 and rs12794714) were genotyped by TaqMan probe assays. The concentration of 25-hydroxyvitamin-D was determined by human enzyme-linked immunosorbent assay (ELISA) kits. The associations of CYP2R1 polymorphisms and risks of vitamin D deficiency (VDD) were analyzed by logistic regression. Multifactor dimensionality reduction (MDR) was used to analyze the gene-environment interaction. Multiple logistic regression was used to examine the effect of CYP2R1 gene variations, and the interaction between CYP2R1 variation and obesity on hypertension susceptibility. The results showed that rs10766197 (GG vs. AA) and rs12794714 (GG vs. AA) polymorphisms were both associated with an increased risk of VDD (OR = 1.49, 95% confidence interval (CI) = 1.08-2.05 and OR = 1.63, 95% CI = 1.19-2.25, respectively), after adjustment for potential risk factors. We also found that rs12794714 polymorphism was significantly associated with elevated risk of hypertension under the dominant model (OR = 1.26, 95% CI = 1.01-1.56). In addition, the interactions between rs12794714 with both general obesity (OR = 3.93, 95% CI = 2.72-5.68) and central obesity (OR = 3.22, 95% CI = 2.29-4.52) have significant effects on hypertension susceptibility. CONCLUSIONS The study provided further evidence that CYP2R1 variation was associated with a higher risk of hypertension in Chinese rural population. The interaction between CYP2R1 rs12794714 and obesity may increase the risk of hypertension.

Abstract
The neutral particles generated by charge exchange reactions can play an important role in erosion of first wall materials in fusion devices. In order to measure the flux and energy of neutral particles to the first wall, a low-energy neutral particle analyzer (LENPA) based on the time-of-flight method has been developed and successfully applied on the Experimental Advanced Superconducting Tokamak (EAST)' to measure the neutrals with an energy of 20-3000 eV. The LENPA works in the counting mode, and the signal of photons is used as the reference for the flight time of neutrals. The energy spectrum of low-energy neutral particles on EAST has been obtained for the first time. The new diagnostics can help in understanding the neutral particle generation and deposition on the first wall materials in tokamaks under different plasma conditions.

Abstract
This study aimed at identifying genomic regions and genes associated with intramuscular fat content (IMF) in Duroc pigs using a weighted single-step GWAS. Data from 3912 pigs, of which 3770 animals were genotyped with GeneSeek Porcine 50K Bead chip, were used for the association analysis. We identified 19 genomic regions that each explained >1% of the additive genetic variance associated with IMF. Notably, a consistent QTL on SSC7 (117.42-117.92 Mb) was confirmed, explaining 3.70% of the additive genetic variance, and two genes, BDKRB2 and ATG2B, were highlighted as promising candidates for IMF. Two QTL (SSC7, 94.19-94.64 Mb; SSC14, 123.25-123.75 Mb), which harbored MED6 and MAP3K9 genes and TCF7L2 gene respectively, were newly identified as associated with IMF. In conclusion, we identified a consistent QTL and additional genomic regions and genes that contributed to the genetic variance of IMF using a large-scale sample size of genotyped pigs and genealogical information.

Abstract
Abstract
Background
There have been few practical and precise tools to predict response after cardiac resynchronisation therapy (CRT).
Purpose
We intend to develop predictive models using machine learning (ML) approaches and easily available features prior to implantation.
Methods
The baseline features of 596 patients receiving CRT were retrospectively collected. Nine predictive models were established, including logistic regression (LR), Elastic Net (EN), lasso regression, ridge regression (Ridge), neural network, support vector machine (SVM), random forest, XGBoost and k-nearest neighbor. Sensitivity, specificity, precision, accuracy, F1, area under receiver operating characteristic curve (AU-ROC) and average precision of each model were evaluated, and AU-ROC was compared between each pair of ML models and further between ML models and the latest guidelines.
Results
Sensitivity was highest with SVM by 0.69, and specificity was highest with LR by 0.81. The models EN and Ridge showed the highest overall predictive power with an average AU-ROC of 0.77. Specifically, the Ridge model provided significant higher AU-ROC than any other model (all P<0.05). All ML models showed significant higher AU-ROC than those derived from the latest guidelines (all P<0.05). Additionally, the effect size analysis identified LBBB, LVESD, and history of PCI as the most crucial predictive features.
Conclusion
ML algorithms produced efficient predictive models for evaluation of response after CRT with features prior to implantation. Tools developed accordingly might improve selection of CRT candidates and reduce rate of non-response in the future.

Abstract
A quartz crystal microbalance (QMB) diagnostic system has been established in Experimental Advanced Superconducting Tokamak (EAST) for real-time and in situ measurements of erosion and deposition rates of plasma-facing materials at the first wall. A ∼70 nm aluminum (Al) film has been coated on the QMB crystal surface to measure the erosion rate by charge exchange neutral particles. Dual sensors of the QMB system have been used with a closed sensor for reference. The stability and light sensitivity of the QMB system have been tested in the lab, demonstrating its feasibility on the application of EAST experiments. The QMB system with cooling water has been successfully applied in the 2018 EAST campaign. The net erosion thickness measured by the QMB has been well validated by thickness measurements using the Rutherford backscattering spectrometry. The developed QMB systems can help us to understand the physics processes of material erosion and deposition at main chamber walls for long pulse operations in EAST.

Abstract
BACKGROUND The aim of this study was to provide information on the semen quality pattern of infertile men and age thresholds for semen parameters in China. METHODS This was a retrospective cross-sectional study investigating 71,623 infertile men from the Reproductive and Genetic Hospital of CITIC Xiangya in Hunan, China, from 2011 to 2017. The Kruskal-Wallis test, Mann-Kendall test, linear regression model and joinpoint regression were used. RESULTS Although erratic changes were observed in the median semen parameters (sperm concentration 40.1-52.1 × 106/ml, total sperm count 117.8-153.1 × 106, sperm progressive motility 33.4-38.1%) during the 7 years of observation, no significant decrease in semen quality was found, and 47.88% of infertile men showed normal semen parameters according to the World Health Organization (WHO) criteria. According to the joinpoint regression analysis, sperm progressive motility appeared to decrease earlier than the sperm concentration and total sperm count (at 28, 58, and 42 years of age, respectively). CONCLUSIONS There is no evidence of a deterioration in semen quality among infertile men in Hunan, China. Semen parameters decreased with increasing age, with turning points noted at different ages. Semen parameters are not absolute evidence for the assessment of male fertility potential. Therefore, we believe that, among semen parameters, the sperm concentration is the best predictor of fertility for ART, followed by motility. Decreased sperm motility may affect natural pregnancy, but it is not necessary for successful IVF.

Abstract
This study aimed to investigate the effect of T cell subsets with different proportions on renal function and blood lipids in patients with preeclampsia (PE). Ninety pregnant women were included in this experiment and classified into 3 groups: group A (30 with severe PE), group B (30 with mild PE) and group C (30 healthy pregnant women). Clinical characteristics were examined. The ratio of T cell subsets in the three groups was detected by flow cytometry. The relationship between PE and T cell subsets was determined. The results showed that no significant difference was found in age or gestational age (P>0.05). The number of CD4+ T cells (CD4 is mainly expressed in helper T cells, referred to as TH) in group A increased significantly compared with group B and group C (P less than 0.05), while the number of CD8+ T cells (CD8+ T cell, also known as cytotoxic T cell (CTL) in group A decreased noticeably in comparison to group C (P less than 0.05). The ratio of CD4+ cell number to CD8+ cell number (TH/CTL) in group A was elevated significantly compared with group B and group C (P less than 0.05). The uric acid (UA) concentration of group A was noticeably elevated compared to group C (P less than 0.05), which differed insignificantly between group B and C (P>0.05). Glomerular filtration rate (GFR) of group A was obviously impaired in comparison to group B and group C (P less than 0.05), which differed insignificantly between group B and C (P>0.05). Total cholesterol (TC) concentrations in group A, C and B were examined. TC concentrations in the former two groups were slightly higher compared to the latter (P less than 0.05), and those in the former two groups were also higher than the normal range (P less than 0.05). Mean triglyceride (TG) concentrations in all 3 groups were above the normal range, and those in group A and B were significantly higher compared to group C (P less than 0.05). TG concentrations differed insignificantly between group B and C (P>0.05). Serum TG, UA and TC in PE patients were positively related to TH/CTL (P less than 0.05). In conclusion, PE is related to T cell subsets, and T cell subsets are closely related to kidney injury and dyslipidemia.

Abstract
To understand the erosion effect of neutral particles on the first wall, a low energy neutral particle analyzer (LENPA), based on the time-of-flight method, has been developed for the Experimental Advanced Superconducting Tokamak (EAST). The LENPA to be installed in the EAST mid-plane mainly consists of a chopper sub-system, a 3 m long flight tube, two sets of detector assemblies, and data acquisition and processing, vacuum, power supply, and control sub-systems. The neutral outflux is gated in bunches of 1 μs time scale by a slotted rotating disc which is driven by a vacuum compatible motor modified from a turbomolecular pump. A He-Ne laser beam is projected through the disc slit to record the instants of chopper slits opening with an avalanche photodiode module. An on-axis electron multiplier detects chopped neutrals, and a central perforated Cu-Be plate is employed to channel the emitted secondary electrons into an off-axis electron multiplier. The radiation peaks of on-axis electron multiplier caused by UV photons projected through the central hole of the Cu-Be plate provide an alternative way to record the chopper slits' opening time. With an additional 4 TB fast memory card, 1 GS/s sampling rate has been realized by using a GaGe acquisition card continuously. The LENPA data from the EAST together with neutral particle material erosion experiments will be used to benchmark the simulation results for better predictions on future fusion reactors, such as ITER and China Fusion Engineering Test Reactor (CFETR).

Abstract
OBJECTIVES To evaluate the performance of a new mathematical model γ-glutamyl transpeptidase to cholinesterase and platelet ratio (GCPR) versus γ-glutamyl transpeptidase to platelet ratio (GPR) in predicting significant fibrosis and cirrhosis of chronic hepatitis B. METHODS A complete cohort of 2343 patients was divided into early and late cohort depending on the time of liver biopsy. With reference to the Scheuer standard, liver pathologic stage 2 or higher and stage 4 or higher were defined as significant fibrosis and cirrhosis, respectively. Receiver operating characteristic (ROC) curve was used to evaluate the performance of investigated models. RESULTS In the early cohort, the areas under ROC curves (AUROCs) of GCPR in predicting significant fibrosis of hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients (0.782 and 0.775) were both significantly greater than those of GPR (0.748 and 0.747) (Z = 8.198 and Z = 6.023, both p <0.0001); the AUROCs of GCPR in predicting cirrhosis of HBeAg-positive and HBeAg-negative patients (0.842 and 0.861) were both significantly greater than those of GPR (0.802 and 0.823) (Z = 6.686 and Z = 6.116, both p <0.0001). In early, late and complete cohorts, using a single cutoff of GCPR > 0.080, the specificities of GCPR in predicting significant fibrosis of HBeAg-positive patients were 83.3%, 88.2% and 85.0% and of HBeAg-negative patients were 87.6%, 87.4% and 87.6%, respectively; and the sensitivities of GCPR in predicting cirrhosis of HBeAg-positive patients were 81.9%, 88.7% and 84.2% and of HBeAg-negative patients were 83.1%, 82.1% and 82.7%, respectively. CONCLUSIONS GCPR has higher performance than GPR in predicting significant fibrosis and cirrhosis of chronic hepatitis B.

Abstract
Objective: To explore the relationship of Crohn's disease (CD) susceptibility to aryl hydrocarbon receptor (AhR) polymorphisms and haplotypes in Han population in Wenzhou city, China. Methods: A total of 310 CD patients and 573 age- and sex-matched healthy controls were enrolled in our study. Three single nucleotide polymorphisms (SNPs) of AhR(rs10249788,rs2158041,rs2066853) were determined by the improved multiple ligase detection reaction technique. Unconditional logistic regression analyses was applied to analyze the allelic and genotypic differences of each SNP between CD patients and controls, as well as their influence on the clinicopathologic characteristics in CD patients. Analyses of linkage disequilibrium and haplotype were performed by Haploview 4.2 software in all study subjects. Results: Compared with the controls, the variant allele (T) and genotype (CT+TT) of (rs2158041) were evidently decreased among CD patients (19.52% vs. 25.04%, P=0.009; 34.19% vs. 44.68%, P=0.003). According to "the Montreal Classification Standards" , CD patients were divided into different subgroups. The variant allele (T) and genotype (CT+TT) of (rs2158041) were significantly lower in patients with terminal ileum CD than in controls (16.79% vs. 25.04%, P=0.005; 28.24% vs. 44.68%, P=0.001). Similar conclusions were also drawn in patients with constricting disease when compared with the controls (15.20% vs. 25.04%, P=0.003; 28.43% vs. 44.68%, P=0.003). The three SNPs above were shown to be in a linkage disequilibrium. Compared with the controls respectively, the frequency of haplotype (CCG) was increased in CD patients (44.73% vs. 39.60%, P=0.039), whereas that of haplotype (CTG) was decreased (18.02% vs. 22.78%, P=0.047). Conclusions: AhR (rs2158041) variation might influence the risk as well as the location and behavior of CD. The haplotype (CCG) possibly increase the risk of CD development, whereas haplotype (CTG) might decrease it.

Abstract
Objective: To investigate the association of ulcerative colitis (UC) with fork head/winged helix transcription factor-3 (Foxp3) polymorphisms in Han population in Zhejiang province, China. Methods: A total of 381 UC patients and 490 healthy controls were enrolled in this study.The four single nucleotide polymorphisms (SNPs) of Foxp3 (rs3761547, rs2232365, rs2294021, rs3761548) were examined by SNaPshot.The analyses of linkage disequilibrium (LD) and haplotype were also performed in all study subjects. Results: When male and female UC patients were compared with their corresponding controls respectively, the alleles and genotypes of the four SNPs were not statistically different (all P>0.05). According to severity and location of the disease, the UC patients were divided into different subgroups. The alleles (C, G, A) of (rs2232365, rs2294021, rs3761548) were more frequent in male patients with severe UC than in the male controls (69.6% vs 34.3%, P=0.001; 69.6% vs 34.3%, P=0.001; 39.1% vs 14.4%, P=0.002, respectively). As compared with the female controls, the alleles (C, G, A) and genotypes (TC+ CC, AG+ GG, CA+ AA) of (rs2232365, rs2294021, rs3761548) were significantly increased in the female patients with severe UC (51.9% vs 38.0%, 63.5% vs 39.2%, 53.8% vs 21.4%, 80.8% vs 57.7%, 84.6% vs 58.4%, 76.9% vs 34.7%, all P<0.05). The four SNPs above were shown to be in a strong LD both in male and in female subjects.When male and female UC patients were compared with their corresponding controls respectively, nevertheless, each haplotype frequency was not statistically different (all P>0.05). Conclusions:Foxp3 (rs2232365, rs2294021, rs3761548) variations might engender the increased risk of severe UC in Chinese Han patients.

Abstract
Interleukin-21 (IL-21) is a cytokine mainly secreted by activated CD4+ T cells and natural killer T cells and has multiple effects. It is involved in innate and adaptive immune responses. Recent studies have shown that IL-21 can promote functional activation of various immune cells in the process of hepatitis B virus (HBV) infection, and the gene polymorphisms of IL-21 is associated with the susceptibility to HBV. In addition, the expression of IL-21 is closely associated with HV genotype, HBV clearance, HBeAg seroconversion, HBV-related liver cirrhosis, liver failure, liver cancer, and autoimmune disease. This article reviews the research advances in clinical trials with reference to the aspects above.

Abstract
The accumulation of H at the small-angle tilt grain boundary (GB) in the W(001) surface is investigated, on the basis of the first-principles calculations. By exploring the solution and diffusion behaviors of H at the GB, we find that the small-angle GB can capture the H atoms nearby, serving as a nucleation site of H bubbles. With the increasing number of trapped H atoms, the GB expands gradually, and the GBs can be unripped with an areal density of H up to 5.0 × 1015 H atoms per cm2, leading to the formation of H bubbles. Moreover, H2 molecules are observed, when the areal density of H atoms in GB is over 6.6 × 1015 atoms per cm2. According to our calculations, we propose a possible formation mechanism of H bubbles observed in the experiment, which is valuable for improving the service performance of W as a plasma-facing material in nuclear fusion reactors.

Abstract
The receptor activator of nuclear factor κB ligand (RANKL)/receptor activator of nuclear factor κB (RANK)/osteoprotegerin (OPG) system plays a key role in rheumatoid arthritis (RA)-associated bone erosion. The upregulation of the RANKL/OPG ratio promotes bone erosion. The objective of this study is to explore the effects of iguratimod, a small-molecule disease-modifying antirheumatic drug (DMARD), alone or in combination with methotrexate (MTX), on RANKL and OPG expression in RA. We performed an enzyme-linked immunosorbent assay (ELISA) to investigate the modulatory effects of iguratimod, MTX, or their combination on serum RANKL and OPG levels of patients with RA before and after treatment for 12 and 24 weeks. Furthermore, fibroblast-like synoviocytes (FLS) from patients with RA were interleukin (IL)-1β-stimulated and then treated with different concentrations of iguratimod, MTX, or both, and RANKL and OPG expressions were investigated by using ELISA, quantitative real-time polymerase chain reaction (qPCR) and western blot analysis. We found that RANKL levels and the RANKL/OPG ratio significantly decreased in both serum and IL-1β-induced RA FLS after treatment. Moreover, combination therapy with iguratimod and MTX showed an even stronger inhibition than each drug alone did. Our results suggest that iguratimod and MTX, especially in combination, efficaciously protected against bone erosion by suppressing the production of RANKL.

Abstract
OBJECTIVE To investigate the association of Crohn's disease (CD) with transcobalamin Ⅱ (TCN2) gene polymorphisms and serum homocysteine (Hcy), folate, and vitamin B12 levels in Chinese patients. METHODS In a total of 307 CD patients (CD group) and 574 healthy controls (control group) of Han ethnicity selected at 4 hospitals in Wenzhou between January 2007 and August 2015, TCN2 gene polymorphisms (rs1801198, C/G; rs9606756, A/G) in peripheral blood were determined using improved multiple ligase detection reaction (iMLDR). The Simplified Crohn's Disease Activity Index (CDAI) was applied to evaluate activity of CD. Eighty-eight CD patients and 138 age- and sex-matched controls were randomly selected from all the study subjects using computer-generated random numbers, in whom serum Hcy level was tested by enzymatic cycling assay, folate and vitamin B12 levels were examined by chemiluminescence immunoassay. RESULTS (1) The mutant allele (G) and genotype (CG+ GG) of rs1801198 were not significantly different between the CD group and the control group (both P>0.05), but more prevalent in patients with stricturing CD than in controls (65.75% vs 56.10%, 93.15% vs 82.40%, both P<0.05). The frequencies of mutant allele (G) and heterozygous genotype (AG) of rs9606756 were higher in CD patients than in controls (2.44% vs 1.05%, 4.89% vs 2.09%, both P<0.05), also higher in patients with stricturing CD or ileocolonic CD compared with controls (stricturing CD: 4.79% vs 1.05%, 9.59% vs 2.09%; ileocolonic CD: 3.18% vs 1.05%, 6.36% vs 2.09%; all P<0.05). The two polymorphic loci (rs1801198 and rs9606756) were shown to be in a weak linkage disequilibrium. The frequency of haplotype (GG) was higher in the CD patients than in the controls (2.23% vs 0.81%, P<0.05). (2) When compared with the controls, the serum Hcy level was higher in the CD patients (P=0.023), whereas the folate and vitamin B12 levels were decreased in the CD patients (both P<0.001). The prevalence of hyperhomocysteinemia (Hcy >15 μmol/L), folate deficiency (folate <4 μg/L) and vitamin B12 deficiency (<203 ng/L) were higher in the CD patients than in the controls (18.18% vs 4.35%, 27.27% vs 5.07%, 31.82% vs 5.07%, all P<0.01). Compared to the patients at remission stage (CDAI<5), the serum Hcy level was increased in those at active stage (CDAI≥5) (P=0.005), while the folate and vitamin B12 levels were decreased in the patients ate active stage (both P<0.05). (3) According to the results of multivariate linear regression analysis, average Hcy level in the CD patients was negatively associated with folate level (β=-0.494, P<0.001), while positively correlated with percentage of neutrophils (β=0.294, P=0.004). Unconditional Logistic regression showed that both folate deficiency and vitamin B12 deficiency were independent risk factors for CD (OR=5.415, OR=7.112, both P<0.001). CONCLUSIONS TCN2 rs1801198 mutation might be associated with increased risk of stricturing CD. TCN2 rs9606756 mutation might be a potential functional locus to affect CD susceptibility. Individuals carrying the haplotype (GG) formed by TCN2 (rs1801198 and rs9606756) seem to be at higher risk of developing CD. Hyperhomocysteinemia, folate deficiency, and vitamin B12 deficiency are prevalent in this cohort of CD patients of Han ethnicity from Zhejiang province. Both folate deficiency and vitamin B12 deficiency are independent risk factors for CD.

Abstract
Adipokines have been known to play a significant role in rheumatic disease via synovial fibroblasts. However, to date, the concentration effects of adiponectin isoforms on the pathophysiology of rheumatoid arthritis (RA) have not been extensively studied. Therefore, the present study examined the different effects of the adiponectin isoforms on rheumatoid arthritis synovial fibroblasts (RASF) and investigated the relations between the concentration of individual adiponectin isoforms and the production of the inflammatory factors of RASF. Articular synovial tissues were obtained from the patients fulfilled with diagnostic criteria of RA, and health people. RASF and human fibroblast—like synoviocytes (HFLS) were isolated and cultured. They were stimulated with increasing concentrations of 25 μg/ml, 50 μg/ml, and 100μg/ml of different human adiponectin isoforms. The levels of matrix metalloproteinase (MMP)—3, MMP—10, tumor necrosis factor (TNF)—α, vascular endothelial growth factor (VEGF), and prostaglandin E2 (PGE2) in culture supernatants were measured by immunoassays. The results showed the levels of MMP—3, MMP—10, TNF—α, VEGF and PGE2 were significantly increased in RASF which were treated with individual adiponectin isoforms compared to untreated RASF (p<0.01), and the increases also had significances compared to HFLS which were treated with the same conditions (p<0.05). Moreover, the effect of HMW (high molecular weight)/ MMW (middle molecular weight) was the strongest among them. In conclusion, all three adiponectin isoforms may contribute to proinflammatory effect by stimulating the production of MMP—3, MMP—10, TNF—α, VEGF and PGE2 of RASF in a concentration—dependent manner. HMW/MMW adiponectin could play an important role in matrix destroying and synovial vascular creating of the pathology of RA.

Abstract
Hemoglobin (Hb) is a major constituent of blood and a potent mediator of oxidative or nitrative stress after intracerebral hemorrhage (ICH). Our previous study demonstrated that Hb could induce abundant peroxynitrite (ONOO(-)) formation in vivo, which may be involved in the blood-brain barrier (BBB) disruption, however, the drug intervention is absent and also the underlying mechanism. Using an experimental stroke model by injecting Hb into the caudate nucleus of male Sprague-Dawley rats, we assessed the role of ONOO(-) decomposition catalyst, 5,10,15,20-tetrakis (4-sulfonatophenyl) porphyrinato iron(III) [FeTPPS] in the activation of MMP-9 and Hb-induced neurovascular injuries. 3-Nitrotyrosine (3-NT, as an index of ONOO(-) formation) and NF-κB expression was measured by western blot (WB) and immunohistochemistry (IHC)/immunofluorescence (IF). Activity of MMP was evaluated by in situ zymography. Neurovascular injury was assessed using zonula occludens-1 (ZO-1) by WB and IF, fibronectin (FN) and neuron-specific nuclear protein (NeuN) IHC. Perihematomal cell death was determined by TUNEL assay. Behavioral outcome was measured by modified neurological severity score (mNSS) test. At the injured striata, profuse 3-NT was produced and mainly expressed in neutrophils and microglia/macrophages. 3-NT formation significantly colocalized with nuclear factor-κB (NF-κB) expression. In situ zymography showed that gelatinase activity was mostly co-localized with neurons and blood vessel walls and partly with neutrophils and microglia/macrophages. Enhanced 3-NT production, NF-κB induction and MMP-9 activation were obviously reduced after FeTPPS treatment. Hb-induced injury to tight junction protein (ZO-1), basal lamina of FN-immunopositive microvasculature and neural cells was evidently ameliorated by FeTPPS. In addition, apoptotic cell numbers as well as behavioral deficits were also improved. The present study shows that the administration of the ONOO(-) decomposition catalyst FeTPPS protects against Hb-induced neurovascular injuries and improves neurological function, which possibly in part by suppressing MMP-9 activation.

Abstract
Nowadays flow-forming has become a desired near net shape manufacturing method as it provides excellent mechanical properties with improved surface finish and significant manufacturing cost reduction. However, the material is subjected to excessive plastic deformation during flow-forming process, generating a very fine and complex microstructure. In addition, the intense dislocation density and residual stress that is generated in the component during processing makes the microstructure characterisation using conventional micro-analytical tools challenging. Thus, the microstructure/property relationship study in such a material is rather difficult. In the present study a flow-formed Cr-Mo-V steel nanostructure and crystallographic texture were characterised by means of Transmission Kikuchi Diffraction (TKD). Here, TKD is shown to be a powerful technique in revealing very fine martensite laths within an austenite matrix. Moreover, fine precipitates in the order of 20-70 nm on the martensite lath boundaries were clearly imaged and characterised. This greatly assisted in understanding the preferable site formation of the carbides in such a complex microstructure. The results showed that the actual TKD spatial resolution was in the range of 5-10 nm using 25 kV for flow-formed Cr-Mo-V steel.

Abstract
Matrix metalloproteinase 11 (MMP11 or stromelysin-3) has recently been reported to play a crucial role in the development and progression of multiple malignancies. The aim of this study was to investigate the function of MMP11 expression in human gastric adenocarcinoma (GAC). Using immunohistochemistry assay, we studied the expression level of MMP11 in GAC and adjacent non-cancerous tissues (ANCT). The association between MMP11 expression and tumor size and pathological grade, as well as metastatic potential was analyzed. Through small hairpin RNA (shRNA)-mediated MMP11 knockdown in SGC-7901 GAC cells, we observed the changes of the biological behaviors of GAC cells. Our results indicated that the rate of positive expression of MMP11 was higher in GAC tissues than in ANCT (55.0 vs 30.0 percent, P=0.025). MMP11 expression had no association with the factors of age or gender of the GAC patients, or the size, pathological staging and lymph node metastases of the tumors (each P greater than 0.05). Furthermore, MMP11 knockdown inhibited the proliferative activities and invasive potential of SGC-7901 GAC cells with decreased expression of IGF-1, PCNA and VEGF. Taken together, our findings demonstrated that MMP11 expression was increased in GAC tissues, but did not correlate with the clinicopathologic features. Knockdown of MMP11 expression could inhibit the proliferation and invasion of GAC cells probably through down-regulation of the IGF-1 signaling pathway, suggesting that MMP11 might be a potential therapeutic target for the treatment of gastric cancer.

Abstract
Results from published studies on the association of Human Oxoguanine Glycosylase 1 (hOGG1) S326C genetic polymorphism with the risk of gastric cancer are inconsistent. We performed a meta-analysis to summarize the possible association. Eleven case-control studies including 2168 cases and 4058 controls were identified from electronic databases (Pubmed, Elsevier Science Direct, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), and the Chinese database, Wanfang). No significant association between hOGG1 S326C genetic polymorphism and risk of gastric cancer was observed in the overall analysis. In the stratified analysis based on ethnicity, still no significant association was observed in Europeans, Asians, or Brazilians. This meta-analysis provided evidence that hOGG1 S326C genetic polymorphism was not associated with increased risk of gastric cancer. However, additional studies with large sample size and better study designs are warranted to verify our finding.
