Abstract
Neuroinflammation plays a key role in many neurodegenerative disorders, including postoperative cognitive decline (POCD). Growing evidence has demonstrated that activation of the peroxisome proliferator-activated receptor-γ (PPARγ) attenuates the inflammatory response and improves cognitive dysfunction associated with many neuropsychiatric disorders. We hypothesize that down-regulation of PPARγ is linked to neuroinflammation and the subsequent cognitive deficits observed in an animal model of POCD. In the present study, the POCD animal model was established by performing an exploratory laparotomy under isoflurane anesthesia in 20-month-old male C57BL/6 mice. Behavioral tests, inflammatory biomarkers, including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β, ionized calcium-binding adaptor molecule-1 (IBA1)-positive cells, as well as glial fibrillary acidic protein (GFAP)-positive cells and brain-derived neurotrophic factor (BDNF), were measured. Herein, we showed that surgery induced profound impairment in cognition that was associated with significant decreases in PPARγ and BDNF expression, and significant increases in IL-1β, IBA1-positive cells, and GFAP-positive cells in the hippocampus. As expected, the PPARγ agonist pioglitazone attenuated the surgery-induced inflammatory changes and rescued the associated cognitive impairment. However, these beneficial effects were abolished by the PPARγ specific antagonist GW9662, suggesting a pivotal role of the PPARγ pathway in the pathogenesis of POCD. Taken together, our results provide evidence that down-regulation of PPARγ may be involved in neuroinflammation and subsequent POCD, and suggest that activation of PPARγ by pioglitazone may represent a new way to prevent or treat POCD.

Abstract
BACKGROUND A simple screening tool may potentially help the migraine diagnosis in a primary care setting. The use of single-item tests, such as stripe pattern hypersensitivity test and self-reported bothersome headache (HA) question, as migraine screening tools have not been fully explored. METHODS Two hundred and fifty-four subjects (patients and companions) were randomly enrolled from an OB/GYN clinic (men 82, women 172; age 38 ± 14). They were instructed to rate the stripe sensitivity level (0-4) and to report any bothersome HA (yes/no). A brief structured HA interview was conducted to describe the HA characteristics and for migraine diagnosis based on the ICHD-IIIβ criteria. RESULTS In a multivariate model, bothersome HA question and stripe pattern hypersensitivity test were both significantly associated with EM+PM+CM (odds ratio: 24.0, P < 0.01 vs 2.6, P = 0.01) or EM (odds ratio: 16.2, P < 0.01 vs 3.0, P < 0.01). Bothersome HA question had a greater screening power than stripe pattern hypersensitivity for screening EM+PM+CM (area under the ROC curve: 0.84 [95% CI 0.78-0.89] vs 0.62 [95% CI 0.55-0.69]) or EM (area under the ROC curve: 0.80 [95% CI 0.73-0.86] vs 0.64 [95% CI 0.56-0.72]). CONCLUSION When performed in an OB/GYN clinic, self-reported bothersome HA question seemed more powerful than visual stripe pattern test in screening migraine thus could potentially be used as a single-item screening test.

Abstract
OBJECTIVE Previous genomewide association studies (GWAS) identified a region near MAFB at chr20q12 associated with non-syndromic orofacial clefts (NSOC) susceptibility. However, whether other SNPs in this area could independently contribute to non-syndromic orofacial clefts in Chinese populations remained obscure. MATERIALS AND METHODS We selected 24 SNPs based on a haplotype-tagging SNP strategy and evaluated their associations with risk of non-syndromic orofacial clefts in a large-scale two-stage case-control study with 1278 cases and 1295 controls. Genotyping was performed with Sequenom and TaqMan assay. Associations between the SNPs and risk of non-syndromic orofacial clefts were estimated from unconditional logistic regression analyses. RESULTS Overall, six SNPs were found to be the susceptible factors of non-syndromic orofacial clefts. The most significant and independent SNP was rs6129653 (additive model of P value = 1.4E-06). In subgroup analysis, its significant associations with cleft lip only (CLO) and cleft lip and palate (CLP) were observed. Furthermore, in silico bioinformatics analysis indicated that rs6129653 was located in the transcriptionally active region and associated with MAFB expression in human brain tissues. CONCLUSIONS Rs6129653 was an independent locus of non-syndromic orofacial clefts among Chinese populations possibly due to its potential of distal transcriptional regulation of MAFB expression.

Abstract
In this study, we evaluated the efficacy and safety of high-dose calcium channel blocker (CCB) monotherapy and standard-dose CCBs combined with angiotensin receptor blockers (ARBs) for patients with hypertension. A comprehensive search of PubMed, Embase and the Cochrane Central Register of Controlled Trials was performed in December 2015. Randomized controlled trials designed to identify the above goal were included. Thirteen trials including 2371 patients were identified. The standard-dose CCB/ARB combination resulted in a greater reduction of systolic blood pressure (WMD -2.52, 95% confidence interval (CI): -3.76 to -1.28) and diastolic blood pressure (weighted mean difference (WMD) -2.07, 95% CI: -3.73 to -0.42) compared to high-dose CCB monotherapy. The overall hypertension control rate for the CCB/ARB combination was higher than that for CCB monotherapy (relative risk (RR): 1.17, 95% CI: 1.08-1.26). Furthermore, the CCB/ARB combination treatment yielded significantly fewer overall adverse events (RR: 0.84, 95% CI: 0.74-0.95), oedema (RR: 0.31; 95% CI: 0.18-0.52) and rash (RR: 0.27, 95% CI: 0.08-0.96, P=0.04) than did CCB monotherapy. The standard-dose CCB/ARB combination is superior to high-dose CCB monotherapy for lowering blood pressure and reducing adverse events in hypertensive patients. Future research should focus on the cost-effectiveness and long-term effects of these two treatment strategies for patients with hypertension.

Abstract
Papillomaviruses (PV) are associated with benign mucosal and cutaneous epithelial proliferations. In dogs, PV-associated pigmented plaques and papillomas can undergo malignant transformation, but this is rare, and most cases of canine squamous cell carcinoma do not arise from PV-induced precursor lesions. We describe herein the progression of pigmented plaques to invasive and metastatic squamous cell carcinoma associated with 2 canine papillomaviruses (CPV) in 2 related Basenji dogs. Immunohistochemistry for PV antigen revealed strong nuclear immunoreactivity within keratinocytes from pigmented plaques from both dogs, consistent with a productive viral infection. Polymerase chain reaction (PCR) using degenerate primers for the L1 gene revealed PV DNA sequences from 2 different CPVs. In situ hybridization for CPV revealed strong hybridization signals within the pigmented plaques and neoplastic squamous epithelial cells from both dogs. We report here progression of PV-associated pigmented plaques to metastatic squamous cell carcinoma within 2 Basenji dogs associated with 2 different CPVs.

Abstract
Short-term outcomes of kidney transplantation have improved dramatically, but chronic rejection and regimen-related toxicity continue to compromise overall patient outcomes. Development of regulatory T cells (Tregs) as a means to decrease alloresponsiveness and limit the need for pharmacologic immunosuppression is an active area of preclinical and clinical investigation. Nevertheless, the immunomodulatory effects of end-stage renal disease on the efficacy of various strategies to generate and expand recipient Tregs for kidney transplantation are incompletely characterized. In this study, we show that Tregs can be successfully generated from either freshly isolated or previously cryopreserved uremic recipient (responder) and healthy donor (stimulator) peripheral blood mononuclear cells using the strategy of ex vivo costimulatory blockade with belatacept during mixed lymphocyte culture. Moreover, these Tregs maintain a CD3(+) CD4(+) CD25(+) CD127(lo) surface phenotype, high levels of intracellular FOXP3 and significant demethylation of the FOXP3 Treg-specific demethylation region on allorestimulation with donor stimulator cells. These data support evaluation of this simple, brief Treg production strategy in clinical trials of mismatched kidney transplantation.

Abstract
BACKGROUND MicroRNAs (miRNAs) play a critical role in responses to biotic and abiotic stress and have been characterized in a large number of plant species. Although flax (Linum usitatissimum L.) is one of the most important fiber and oil crops worldwide, no reports have been published describing flax miRNAs (Lus-miRNAs) induced in response to saline, alkaline, and saline-alkaline stresses. RESULTS In this work, combined small RNA and degradome deep sequencing was used to analyze flax libraries constructed after alkaline-salt stress (AS2), neutral salt stress (NSS), alkaline stress (AS), and the non-stressed control (CK). From the CK, AS, AS2, and NSS libraries, a total of 118, 119, 122, and 120 known Lus-miRNAs and 233, 213, 211, and 212 novel Lus-miRNAs were isolated, respectively. After assessment of differential expression profiles, 17 known Lus-miRNAs and 36 novel Lus-miRNAs were selected and used to predict putative target genes. Gene ontology term enrichment analysis revealed target genes that were involved in responses to stimuli, including signaling and catalytic activity. Eight Lus-miRNAs were selected for analysis using qRT-PCR to confirm the accuracy and reliability of the miRNA-seq results. The qRT-PCR results showed that changes in stress-induced expression profiles of these miRNAs mirrored expression trends observed using miRNA-seq. Degradome sequencing and transcriptome profiling showed that expression of 29 miRNA-target pairs displayed inverse expression patterns under saline, alkaline, and saline-alkaline stresses. From the target prediction analysis, the miR398a-targeted gene codes for a copper/zinc superoxide dismutase, and the miR530 has been shown to explicitly target WRKY family transcription factors, which suggesting that these two micRNAs and their targets may significant involve in the saline, alkaline, and saline-alkaline stress response in flax. CONCLUSIONS Identification and characterization of flax miRNAs, their target genes, functional annotations, and gene expression patterns are reported in this work. These findings will enhance our understanding of flax miRNA regulatory mechanisms under saline, alkaline, and saline-alkaline stresses and provide a foundation for future elucidation of the specific functions of these miRNAs.

OBJECTIVE Irisin, a newly discovered myokine, can drive the browning of white adipocytes to control body weight or mitigate obesity progression through regulating energy metabolism. However, the underlying mechanisms or specific signal pathways of exercise-induced irisin on the management of obesity are still unclear. MATERIALS AND METHODS Totally 30 rats were subjected to high fat diet (HFD) feeding for 8 weeks to establish the rat model with obesity successfully. HFD-induced obese model rats were provided with 8 weeks swimming intervention at moderate intensity for exploring the treatment of obesity through exercise intervention. In addition, another 15 rats were subjected to HFD feeding coupled with total 16 weeks swimming intervention at a moderate intensity from the beginning of the experiment, which was used for exploring the prevention of obesity through exercise intervention. Blood and gastrocnemius samples were harvested from obese rats after swimming intervention to explore its specific signal pathways through ELISA analysis and Western blotting. RESULTS HFD feeding of rats for 8 weeks could lead to the obesity due to the disorders of lipid metabolism. Totally 8 weeks swimming intervention at moderate intensity for rats with obesity could obviously alleviate the progression of obesity and 16 weeks swimming intervention from the beginning of the experiment could significantly inhibit the development of obesity. Meanwhile, swimming intervention could result in an increased phosphorylation of AMPK and up-regulation of irisin and PGC-1α as the biomarkers of energy metabolism. CONCLUSION Exercise intervention can activate PGC-1α-dependent irisin to induce the browning of white adipocytes, thus inhibiting or alleviating the occurrence and development of obesity.

Abstract
Although NOD-SCID IL2Rγ-/- (NSG) xenograft mice are currently the most frequently used model to study human leukemia in vivo, the absence of a human niche severely hampers faithful recapitulation of the disease. We used NSG mice in which ceramic scaffolds seeded with human mesenchymal stromal cells were implanted to generate a human bone marrow (huBM-sc)-like niche. We observed that, in contrast to the murine bone marrow (mBM) niche, the expression of BCR-ABL or MLL-AF9 was sufficient to induce both primary acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL). Stemness was preserved within the human niches as demonstrated by serial transplantation assays. Efficient engraftment of AML MLL-AF9 and blast-crisis chronic myeloid leukemia patient cells was also observed, whereby the immature blast-like phenotype was maintained in the huBM-sc niche but to a much lesser extent in mBM niches. We compared transcriptomes of leukemias derived from mBM niches versus leukemias from huBM-like scaffold-based niches, which revealed striking differences in the expression of genes associated with hypoxia, mitochondria and metabolism. Finally, we utilized the huBM-sc MLL-AF9 B-ALL model to evaluate the efficacy of the I-BET151 inhibitor in vivo. In conclusion, we have established human niche models in which the myeloid and lymphoid features of BCR-ABL+ and MLL-AF9+ leukemias can be studied in detail.

Abstract
UNLABELLED WHAT IS KNOWN ON THE SUBJECT?: The TAS-20 is the most widely used self-reported questionnaire to assess the level of alexithymia in students and community and clinical samples. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The TAS-20-C exhibited high levels of reliability and validity, indicating that it is appropriate for the assessment of alexithymia in Chinese adolescents. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Screening adolescents who are at risk of alexithymia through the TAS-20 could help to perform necessary and effective precautions to decrease the adverse effects of alexithymia, such as the risks of developing depressive mood and behavioral problems. ABSTRACT Purpose The aim of this study was to examine the psychometric properties of the Chinese version of the 20-item Toronto Alexithymia Scale (TAS-20-C) in a sample of Chinese adolescents. Method Adolescents (n = 1260) recruited from three schools in mainland China completed the TAS-20-C, the somatization subscale of the Symptom Checklist 90 (SCL-90) and Center for Epidemiological Studies Depression Scale (CES-D). Five different factorial models of the TAS-20 were tested using confirmatory factor analysis (CFA). Cronbach's α, mean inter-item correlations and predictive validity were also evaluated. Results Among those five different factorial models, the four-factor structure model was suitable and invariant across gender and age in this sample. The TAS-20-C demonstrated adequate internal reliability. Gender and age accounted for insignificant amounts of variability in total TAS-20-C and factor scores. TAS-20-C total and subscale scores were correlated significantly with SCL-90 somatization subscale and CES-D. Girls scored higher than boys on difficulty identifying feelings (DIF) and pragmatic thinking (PR) subscales. DIF and lack of subjective significance or importance of emotions (IMs) subscale scores were higher among younger than among middle and older adolescents. Implications for Practice Validating the TAS-20 in adolescents is quite important to use it in evaluating adolescents' alexithymia, and screen those at risk of alexithymia.

Abstract
We investigated the possible correlations between N-acetyltransferase-2 (NAT2) gene polymorphisms and the risk of coronary heart disease (CHD). CHD patients (113) and healthy controls (118) were enrolled from the First People's Hospital of Yuhang between January 2013 and June 2014. The patients were divided into mild CHD (N = 72) and severe CHD (N = 41) subgroups. DNA samples were extracted and the distributions of NAT2 polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Clinical characteristic indexes of severe CHD patients were also examined for relevant statistical analysis. WT, M1, M2, and M3 alleles were observed in both case and control groups. PCR-RFLP identified a wild-type homozygote, WT/WT; a mutant heterozygote, WT/Mx; and a mutant homozygote, Mx/Mx (x = 1, 2, and 3) variant of the NAT2 genotype. Mx/Mx differed significantly between case and control groups (P < 0.05); the frequencies of all four alleles did not differ significantly between case and control groups (P > 0.05). Slow acetylator genotype frequencies were notably higher in the case group than in the control group (P < 0.05). Individuals with the slow acetylator genotype were at 1.97-times higher risk of CHD and also displayed higher triglyceride and lower high-density lipoprotein cholesterol levels than those with the rapid acetylator genotype (P < 0.05). Therefore, the NAT2 polymorphism was believed to be associated with increased risk of CHD, with the NAT2 slow acetylator genotype serving as a risk factor for severe CHD in a Chinese population.

Abstract
BACKGROUND The goal of the present study was to investigate the osteogenic potential of ligament fibroblasts from patients with ankylosing spondylitis (AS). MATERIALS AND METHODS Ligament fibroblasts were isolated from tissues harvested from AS patients and patients with aseptic necrosis of the femoral head (ANFH) who had undergone total hip arthroplasty (THA). Cells were cultured in osteogenic induction medium (OIM) with or without bone morphogenetic protein 2 (BMP-2) for 30 days. During this time, the levels of alkaline phosphatase (ALP) and osteocalcin (OC) were determined as markers of osteogenesis. RESULTS Ligament fibroblasts isolated from patients with AS exhibited significantly greater potential for differentiation than those isolated from patients with osteoarthritis (ANFH). CONCLUSION These findings illuminate osteogenesis as a new pathway for studying the mechanism underlying ankylosis in AS patients. Factors which cause localized stromal remodeling at the enthesis significantly influence formation of new bone and further research is required to determine the mechanisms responsible for the osteogenic potential of enthesis cells and ligament fibroblasts in AS patients.

Abstract
This study aims to investigate the serum T-cell immunoglobulin mucin (TIM)-1 and TIM-3 levels in systemic lupus erythematosus (SLE) patients and analyze their correlations with clinical features. Sixtyone SLE patients and 69 healthy controls were enrolled, serum TIM-1 and TIM-3 levels were detected by ELISA. Results demonstrated that both serum TIM-1 and TIM-3 levels were significantly decreased in SLE patients compared with controls (both P less than 0.05). Lower serum TIM-3 levels in SLE patients with nephritis were observed when compared to those without nephritis, with a marginal statistical significance (P=0.059). However, both serum TIM-1 and TIM-3 levels had no significant correlation with SLE disease activity (both >0.05). In summary, decreased serum TIM-1 and TIM-3 levels and association of TIM-3 with nephritis suggest their possible role in the development and pathogenesis of SLE. However, further studies are needed to confirm these preliminary results.

Abstract
Somatic embryogenesis (SE) has been studied as a model system to understand molecular events in physiology, biochemistry, and cytology during plant embryo development. In particular, it is exceedingly difficult to access the morphological and early regulatory events in zygotic embryos. To understand the molecular mechanisms regulating early SE in Eleutherococcus senticosus Maxim., we used high-throughput RNA-Seq technology to investigate its transcriptome. We obtained 58,327,688 reads, which were assembled into 75,803 unique unigenes. To better understand their functions, the unigenes were annotated using the Clusters of Orthologous Groups, Gene Ontology, and Kyoto Encyclopedia of Genes and Genomes databases. Digital gene expression libraries revealed differences in gene expression profiles at different developmental stages (embryogenic callus, yellow embryogenic callus, global embryo). We obtained a sequencing depth of >5.6 million tags per sample and identified many differentially expressed genes at various stages of SE. The initiation of SE affected gene expression in many KEGG pathways, but predominantly that in metabolic pathways, biosynthesis of secondary metabolites, and plant hormone signal transduction. This information on the changes in the multiple pathways related to SE induction in E. senticosus Maxim. embryogenic tissue will contribute to a more comprehensive understanding of the mechanisms involved in early SE. Additionally, the differentially expressed genes may act as molecular markers and could play very important roles in the early stage of SE. The results are a comprehensive molecular biology resource for investigating SE of E. senticosus Maxim.

Abstract
The recycling of waste plastics is an important aspect in the recycling of solid waste. Based on the difference in density, PET and PVC particles was separated with help of the centrifugal sedimentation and shearing dispersion in a hydrocyclone. Through tests and CFD simulation, the relationship between the separating efficiency and pressure drop and split ratio has been investigated. Test results show that the Newton efficiency can reach above 80%, i.e. the purity of PVC could reach 93.2% while the purity of PET could reach 94.5%.

Abstract
OBJECTIVE Spinal cord injury (SCI), as one of the common serious spine disorders, often leads to severe neurological dysfunction and even permanent disability, which will cause heavy economical burden for family and society. Currently, selenium-enriched products have an obvious role in the protection and recovery of SCI; however, its protective mechanism is still unclear. MATERIALS AND METHODS In order to explore the protective effect of selenium-enriched supplement (SES) on SCI, the adult rats were randomly divided into sham operation control (SC) group, ischemia-reperfusion model (IM) group and SES pretreatment (ST) group to investigate the change of ciliary neurotrophic factor (CNTF) and its receptor-alpha (CNTF-Ralpha) during SCI in the presence of SES. The rats in IM and ST groups were subjected to the blockage of their abdominal aorta to establish the model of SCI; but the rats in SC group were subjected to sham operation without the blockage of abdominal aorta. The rats in ST group were fed with foods containing SES at the dose of equivalent 5 mg/L selenium in water before blocking their abdominal aorta. After 7 days, the rats were sacrificed to observe the structure of nerve cells through HE staining and the expression of CNTF and CNTF-Ralpha by Western blot, immunohistochemical, and RT-PCR methods, respectively. RESULTS Both protein and mRNA of CNTF and CNTF-Ralpha were positively expressed in rats from SC group. The mRNA expression levels of CNTF and CNTF-Ralpha in ST group were much higher than SCI model group. CONCLUSIONS SES can execute a protective role in SCI through up-regulating the expression of CNTF and CNTF-Ralpha.

Abstract
It has been reported that surface microstructural dimensions can influence the osteoinductivity of calcium phosphates (CaPs), and osteoclasts may play a role in this process. We hypothesised that surface structural dimensions of ≤ 1 μm trigger osteoinduction and osteoclast formation irrespective of macrostructure (e.g., concavities, interconnected macropores, interparticle space) or surface chemistry. To test this, planar discs made of biphasic calcium phosphate (BCP: 80% hydroxyapatite, 20% tricalcium phosphate) were prepared with different surface structural dimensions - either ~ 1 μm (BCP1150) or ~ 2-4 μm (BCP1300) - and no macropores or concavities. A third material was made by sputter coating BCP1150 with titanium (BCP1150Ti), thereby changing its surface chemistry but preserving its surface structure and chemical reactivity. After intramuscular implantation in 5 dogs for 12 weeks, BCP1150 formed ectopic bone in 4 out of 5 samples, BCP1150Ti formed ectopic bone in 3 out of 5 samples, and BCP1300 formed no ectopic bone in any of the 5 samples. In vivo, large multinucleated osteoclast-like cells densely colonised BCP1150, smaller osteoclast-like cells formed on BCP1150Ti, and osteoclast-like cells scarcely formed on BCP1300. In vitro, RAW264.7 cells cultured on the surface of BCP1150 and BCP1150Ti in the presence of osteoclast differentiation factor RANKL (receptor activator for NF-κB ligand) proliferated then differentiated into multinucleated osteoclast-like cells with positive tartrate resistant acid phosphatase (TRAP) activity. However, cell proliferation, fusion, and TRAP activity were all significantly inhibited on BCP1300. These results indicate that of the material parameters tested - namely, surface microstructure, macrostructure, and surface chemistry - microstructural dimensions are critical in promoting osteoclastogenesis and triggering ectopic bone formation.

Abstract
Mechanical wounding or treatment with exogenous jasmonates (JA) induces differentiation of the laticifer in Hevea brasiliensis. JA is a key signal for latex biosynthesis and wounding response in the rubber tree. Identification of JAZ (jasmonate ZIM-domain) family of proteins that repress JA responses has facilitated rapid progress in understanding how this lipid-derived hormone controls gene expression and related physiological processes in plants. In this work, the full-length cDNAs of six JAZ genes were cloned from H. brasiliensis (termed HbJAZ). These HbJAZ have different lengths and sequence diversity, but all of them contain Jas and ZIM domains, and two of them contain an ERF-associated amphiphilic repression (EAR) motif in the N-terminal. Real-time RT-PCR analyses revealed that HbJAZ have different expression patterns and tissue specificity. Four HbJAZ were up-regulated, one was down-regulated, while two were less effected by rubber tapping treatment, suggesting that they might play distinct roles in the wounding response. A yeast two-hybrid assay revealed that HbJAZ proteins interact with each other to form homologous or heterogeneous dimer complexes, indicating that the HbJAZ proteins may expand their function through diverse JAZ-JAZ interactions. This work lays a foundation for identification of the JA signalling pathway and molecular mechanisms of latex biosynthesis in rubber trees.

Abstract
The aim of the study was to optimize the biological safety scheme of spinal image-guided radiotherapy (IGRT) by determining the expression of caspase-3 in spinal cord neurons after IGRT. Thirty-six adult male beagles were assigned according to a random number table and subjected to IGRT to the 7th-12th canine thoracic vertebral bodies under a total dose of 80 Gy over 5 weeks. An immunohistochemical method was used to detect the expression of caspase-3 protein in spinal cord tissues, and real-time quantitative RT-PCR with SYBR Green I was used to detect the expression of caspase-3 mRNA in spinal cord tissues. Analysis of the orthogonal experiment results showed that caspase-3 expression in the spinal cord neurons was lowest when a single dose of 16 Gy was applied at a dose rate of 4 Gy/min, and field number of 9, with ray angle being equal. Thus, spinal IGRT showed high biological safety, and the best radiotherapy scheme for biological safety was single dose of 16 Gy at 4 Gy/min, with 9 fields and equal ray angle.

Abstract
This study investigated the incidence and development of pneumoconiosis in the Xinjiang Uygur Autonomous Region and cases reported by the Urumqi Railway Bureau to provide a scientific basis for developing prevention and control measures against pneumoconiosis. Data from pneumoconiosis cases were input into Excel and analyzed by SPSS version 17.0. There were 13,165 cases of pneumoconiosis through 2010. Coal workers accounted for the largest proportion of cases. From July 2006 through 2010, a total of 1233 new cases of pneumoconiosis were reported in the Xinjiang Uygur Autonomous Region; most cases were reported in Urumqi. From 1981 to 2012, 3332 new cases of pneumoconiosis had been confirmed by the Urumqi Railway Bureau, including 77.73, 16.96, and 5.31% stage I, II, and III cases, respectively. In the last 30 years, the number of new pneumoconiosis cases peaked in 1986; most of them were silicosis cases. In addition, there were more than 200 cases of pneumoconiosis combined with pulmonary tuberculosis reported by the Urumqi Railway Bureau. The coal industry in Urumqi is the main industry in which occupational pneumoconiosis occurs in Xinjiang. Thus, substantial effort is still required to eliminate pneumoconiosis by 2030.

Abstract
AIM Muscle-type carnitine palmitoyltransferase 1 (CPT1b) plays an important role in skeletal muscle mitochondrial fatty acid β-oxidation. A myocyte-specific enhancer factor (MEF2) site that binds MEF2A in the promoter of Cpt1b has been identified. The aim of this study is to determine whether Cpt1b expression is regulated by MEF2 in response to exercise training. METHODS Twelve male, 14-week-old C57BL/6 mice underwent 6 weeks of treadmill exercise at 12 m min(-1), for 60 min day(-1), 5 days week(-1). Quadriceps muscles were analysed by real-time PCR, Western blot, chromatin immunoprecipitation. RESULTS The binding of MEF2A to the Cpt1b promoter was elevated in the quadriceps muscle of mice after 6-week aerobic exercise intervention. The repressor partner of MEF2, histone deacetylase 5 (HDAC5), binding to the Cpt1b promoter was decreased by exercise training. In C2C12 myoblast, MEF2A overexpression increased the Cpt1b mRNA expression and the Cpt1b promoter transcriptional activity, which were suppressed by HDAC5. Moreover, exercise training induced MEF2A hyperacetylation, which is strongly associated with its enhanced DNA-binding ability. The binding of both HDAC5 and histone deacetylase 3 (HDAC3) to MEF2A was decreased by exercise training. Overexpression of HDAC5 decreased exogenous MEF2A acetylation level with an increased binding of endogenous HDAC3 to MEF2A. Finally, the phosphorylation levels of HDAC5 Ser259 and Ser498 were increased by exercise training. Exercise training decreased the abundance of HDAC5 in the nucleus while increasing its abundance in the cytoplasm. CONCLUSION Our results indicated that exercise-induced CPT1b expression was at least in part mediated by HDAC5/MEF2A interaction.

Abstract
The salinization and alkalization of soil are widespread environmental problems, and alkaline salt stress is more destructive than neutral salt stress. Therefore, understanding the mechanism of plant tolerance to saline-alkaline stress has become a major challenge. However, little attention has been paid to the mechanism of plant alkaline salt tolerance. In this study, gene expression profiling of flax was analyzed under alkaline-salt stress (AS2), neutral salt stress (NSS) and alkaline stress (AS) by digital gene expression. Three-week-old flax seedlings were placed in 25 mM Na2CO3 (pH11.6) (AS2), 50mM NaCl (NSS) and NaOH (pH11.6) (AS) for 18 h. There were 7736, 1566 and 454 differentially expressed genes in AS2, NSS and AS compared to CK, respectively. The GO category gene enrichment analysis revealed that photosynthesis was particularly affected in AS2, carbohydrate metabolism was particularly affected in NSS, and the response to biotic stimulus was particularly affected in AS. We also analyzed the expression pattern of five categories of genes including transcription factors, signaling transduction proteins, phytohormones, reactive oxygen species proteins and transporters under these three stresses. Some key regulatory gene families involved in abiotic stress, such as WRKY, MAPKKK, ABA, PrxR and ion channels, were differentially expressed. Compared with NSS and AS, AS2 triggered more differentially expressed genes and special pathways, indicating that the mechanism of AS2 was more complex than NSS and AS. To the best of our knowledge, this was the first transcriptome analysis of flax in response to saline-alkaline stress. These data indicate that common and diverse features of saline-alkaline stress provide novel insights into the molecular mechanisms of plant saline-alkaline tolerance and offer a number of candidate genes as potential markers of tolerance to saline-alkaline stress.

Abstract
A current challenge of synthetic bone graft substitute design is to induce bone formation at a similar rate to its biological resorption, matching bone's intrinsic osteoinductivity and capacity for remodelling. We hypothesise that both osteoinduction and resorption can be achieved by altering surface microstructure of beta-tricalcium phosphate (TCP). To test this, two TCP ceramics are engineered with equivalent chemistry and macrostructure but with either submicron- or micron-scale surface architecture. In vitro, submicron-scale surface architecture differentiates larger, more active osteoclasts--a cell type shown to be important for both TCP resorption and osteogenesis--and enhances their secretion of osteogenic factors to induce osteoblast differentiation of human mesenchymal stem cells. In an intramuscular model, submicrostructured TCP forms 20 % bone in the free space, is resorbed by 24 %, and is densely populated by multinucleated osteoclast-like cells after 12 weeks; however, TCP with micron-scale surface architecture forms no bone, is essentially not resorbed, and contains scarce osteoclast-like cells. Thus, a novel submicron-structured TCP induces substantial bone formation and is resorbed at an equivalent rate, potentially through the control of osteoclast-like cells.

Abstract
MSX1 is a favorable candidate gene for susceptibility to non-syndromic orofacial clefts (NSOCs). However, the roles of MSX1 genetic variants in the development of NSOC are controversial and vary among human populations. In the present study, the roles of 4 potentially functional single-nucleotide polymorphisms (SNPs) of MSX1 (rs12532 in 3′-untranslated region [UTR], and rs3821947, rs3821949, and rs4464513 in 5′ upstream) were investigated in a case-control study of 602 NSOC cases and 605 healthy controls. The findings showed that rs12532 located within 3′-UTR of MSX1 could influence the risk of developing NSOC. Individuals who carried the variant genotype (rs12532AA genotype) showed a decreased possibility of developing NSOC (AA vs. GG: OR = 0.69, 95% CI = [0.49, 0.98]). Interestingly, similar effects were also observed on cleft lip with palate (CLP), in a stratified analysis (allelic comparison-12532A allele vs. 12532G allele, OR = 0.80, 95% CI = [0.66, 0.99]; genotypic comparison-AA vs. GG, OR = 0.58 95% CI = [0.37, 0.91]). Sequence analysis indicated that this SNP might alter the binding ability of miR-3649, confirmed by luciferase activity assay showing a lower expression level of rs12532 A allele compared with that of the G allele ( p < .001 for 293A and COS7 cell lines). Furthermore, an in vivo study showed that MSX1 expression among individuals carrying the AA genotype of rs12532 was markedly lower than that in those with the GG genotype, while the inverse correlation was observed for miR-3649, thus providing a possible interaction between MSX1 and miR-3649 in the etiology of NSOC. Taken together, these findings indicate that SNPs in the miRNA-binding sites might play an important role in the development of NSOCs. Furthermore, if confirmed in subsequent studies, the polymorphisms may be considered as additional markers for the evaluation of infants’ risk of NSOCs.

Abstract
In the treatment of orbital floor fractures, bone is ideally regenerated. The materials currently used for orbital floor reconstruction do not lead to the regeneration of bone. Our objective was to render polymeric materials based on poly(trimethylene carbonate) (PTMC) osteoinductive, and to evaluate their suitability for use in orbital floor reconstruction. For this purpose, osteoinductive biphasic calcium phosphate (BCP) particles were introduced into a polymeric PTMC matrix. Composite sheets containing 50 wt% BCP particles were prepared. Also laminates with poly(D,L-lactide) (PDLLA) were prepared by compression moulding PDLLA films onto the composite sheets. After sterilisation by gamma irradiation, the sheets were used to reconstruct surgically-created orbital floor defects in sheep. The bone inducing potential of the different implants was assessed upon intramuscular implantation. The performance of the implants in orbital floor reconstruction was assessed by cone beam computed tomography (CBCT). Histological evaluation revealed that in the orbital and intramuscular implantations of BCP containing specimens, bone formation could be seen after 3 and 9 months. Analysis of the CBCT scans showed that the composite PTMC sheets and the laminated composite sheets performed well in orbital floor reconstruction. It is concluded that PTMC/BCP composites and PTMC/BCP composites laminated with PDLLA have osteoinductive properties and seem suitable for use in orbital floor reconstruction.

Abstract
BACKGROUND Mesohepatectomy (MH) avoids unnecessary sacrifice of functional parenchyma compared with extended hepatectomy (EH). The aim of this study was to compare the results of MH with those of EH in the management of centrally located liver tumours (CLLTs). METHODS All patients with CLLTs treated by liver resection between 2005 and 2011 were enrolled in this retrospective study. The decision to use MH or EH was made on an individual basis. Outcomes of the procedures were compared and a classification system for MH was devised consisting of four types, with type IV representing the most complex procedure. RESULTS MH was performed in 292 patients and EH in 138. MH was associated with a longer duration of operation (P < 0.001), higher intraoperative transfusion rate (P < 0.001) and lower complication rates (P = 0.001) compared with EH. There were no significant differences in hepatic inflow occlusion rate (P = 0.075), blood loss (P = 0.241) and length of hospital stay (P = 0.804) between the two groups. Type IV lesions had the longest duration of operation, greatest blood loss, and highest intraoperative transfusion and morbidity rates (all P < 0.050). CONCLUSION MH is a feasible and safe alternative to EH in selected patients with CLLTs. The proposed classification system may be useful in guiding the surgical treatment of CLLTs.

Abstract
OBJECTIVE To discuss the surgical methods of total knee arthroplasty (TKA) in the patients with active tuberculosis of the knee and find out its curative effect after TKA. PATIENTS AND METHODS We analyzed 10 patients with active tuberculosis of the knee who received TKA in our department from March 2006 to March 2010, whose ages were from 22 to 64 years old (average age was 40.6 ± 1 years). The following parameters were measured in the pre- and post-operation periods: HSS score, range of motion (ROM). From x-ray to find out post-operate curative effect of TKA. RESULTS All cases had pain and elevated ESR. Deep vein thrombosis (DVT) and nerve damage were not found in these cases. There were 4 cases that had sinuses on the skin: the skin healed before the operation took place. Pre-operation HSS average scores were 25.0 ± 2. All patients received TKA by the para-patellar medial approach. Eight cases were followed-up for 6-28 months; the average follow-up period was 14 ± 0.5 months. Post-operation we took an HSS score and X-rays to find out its curative effect after TKA operation. There were also no patients with dislocation, aseptic loosening or fracture of prosthesis, although 1 case had recurrence. Post-operation's HSS average scores were 86.75 ± 5.45. The average ROM was improved to 95 ± 5°. CONCLUSIONS Recent clinical results indicate that TKA is effective to treat the patients with active tuberculosis of the knee joint. TKA can significantly improve the function of the joint and relieve pain, improving patients' living conditions.

Abstract
OBJECTIVE The purpose of this study is to evaluate potential associations between vascular endothelial growth factor (VEGF) gene polymorphisms and ectopic pregnancy (EP) in Chinese women. MATERIALS AND METHODS This was a case-control study wherein 192 women with a history of EP were compared to 210 post-menopausal controls with two pregnancies and no EP for the genotyping of VEGF polymorphisms. Genotyping of the VEGF gene polymorphisms at -460C/T, -1 154G/A, -2578C/A and +936C/T were performed by polymerase chain reaction-restriction fragment length polymorphism. RESULTS No significant differences were found in genotype and allele distributions of the -460C/T, +936C/T polymorphisms between cases and controls. Compared with the -1154G/G genotype, the -1154(A/A+G/A) genotype could significantly reduce the risk of developing EP. For the -2578C/A polymorphism, the A/A+C/A geno- type could significantly decrease the risk of developing EP, compared with the C/C genotype. The haplotype analysis suggested that the TAA (VEGF -460/-1154/-2578) and CAA haplotypes could significantly decrease the risk of developing EP compared with the haplotype of TGC. CONCLUSION The -1154A or -2578A alleles of VEGF gene could significantly decrease the risk of EP and might be po- tentially protective factors for EP development in Chinese women.

Abstract
CONTEXT Osteoporosis is a systemic disease with a strong genetic component. Calcitonin receptors (CTR) are involved in maintaining calcium homeostasis. There is no consensus whether CTR gene polymorphism plays a role in affecting pathogenesis of osteoporosis. OBJECTIVE The objective of this study was to investigate genetic susceptibility of calcitonin receptor gene polymorphism (genotypes and allele frequencies) to primary osteoporosis between Han and Uygur patients and healthy controls in the Chinese Xinjiang region. DESIGN This was a cross-sectional study conducted in an academic hospital. SUBJECTS Between 2010 and 2012 a total of 404 female patients with primary osteoporosis (200 Han and 204 Uygur) and 316 healthy control subjects (160 Han and 156 Uygur) were recruited to determine the distribution of C/T single nucleotide polymorphism of the CTR gene. PCR-restriction fragment length polymorphism was used at the 1377-bp site. RESULTS The frequency of polymorphic C/T alleles of the calcitonin receptor gene in each group fit the Hardy-Weinberg equilibrium model. There was no statistically significant difference in genotypes (P = 0.922) or allele frequency (P = 0.654) between the Xinjiang Han postmenopausal osteoporosis patients and the controls. Similarly, there was no difference in genotypes (P = 0.897) or allele frequency (P = 0.825) between Xinjiang Uygur postmenopausal osteoporosis patients and the controls. Moreover, there was no significant difference (P = 0.86) between the combination of both ethnic groups and controls. In contrast, compared to these two ethnic groups, Han CC type accounted for 67.8%, CT 30.0%, and TT 2.2%, whereas Uighur CC type accounted for 55.6%, CT 33.3%, and TT 11.2%, which is statistically significant between Han and Uygur CTR genotypes (P = 0.006). Allele frequency of C accounted for 82.8% and T for 17.2% in Han, whereas C accounted for 72.2% and T for 27.8% in Uygur (P = 0.001). CONCLUSION There was no statistically significant difference in CTR gene nucleotide sequence polymorphisms at 1377-bp between Chinese Xinjiang Han and Uygur patients with primary osteoporosis, suggesting that this CTR gene polymorphism may not affect incidence of osteoporosis. However, there was a significant difference in CTR gene nucleotide sequence polymorphism at the 1377-bp site between Chinese Xinjiang Han and Uygur, but the importance of this difference needs further study.

Abstract
BACKGROUND Salt sensitivity is an important cause of hypertension which is a major public health problem. This study aimed to investigate the contribution of Cytochrome P450 (CYP) to salt-sensitive hypertension with microarray data and bioinformatics analysis. METHODS Gene expression data set GSE4800 was downloaded from Gene Expression Omnibus database, including 6 gene chips from 3 Dahl salt sensitive (DS) rat samples and 3 Lewis (LEW) rat samples. Raw data were preprocessed and normalized, and then differentially expressed genes (DEGs) were identified with Limma package. Interaction network was constructed by employing STRING (Search Tool for the Retrieval of Interacting Genes) tool. GO (Gene Ontology) enrichment analysis was performed using FuncAssociate tool and pathway analysis was carried out by EASE (Expressing Analysis Systematic Explorer). BLAST (Basic Local Alignment Search Tool) was applied to explore the sequence homology among CYP3A genes in rat and human based on multiple alignments. RESULTS A total of 1264 DEGs, including 1082 up-regulated genes and 182 down-regulated genes were identified between DS and LEW samples. CYP3A2 and CYP3A9 were selected to construct the protein interaction network, which comprised 1653 pairs of interaction relationship among 100 genes. Functional analysis showed that CYP3A2 and CYP3A9 were most significantly related to oxidation reduction and metabolism of xenobiotics by cytochrome P450. Furthermore, the CYP3A2 and CYP3A9 genes in rats had high homology with genes CYP3A4and CYP3A5 in human beings. CONCLUSIONS CYP3A4 and CYP3A5 may contribute to salt-sensitive hypertension in human which may act as biomarkers for this disease.
