Abstract
OBJECTIVE Small-caliber expanded polytetrafluoroethylene (ePTFE) grafts cannot be used widely in the clinical situation because of early thrombosis and occlusion. This unsolved and under-recognized problem warrants further investigation. METHODS Grafts of uncoated ePTFE (n = 6) and anti-CD34-coated ePTFE (n = 6) were implanted unilaterally into the carotid artery in 12 domestic pigs. Ultrasonography was used to test the proximal and distal anastomotic stoma morphology, diameters and blood velocities. A thrombosis instrument was used to examine the blood coagulation state. After seven days, the pigs were sacrificed and the implanted grafts were excised for general and histological analysis. Computational fluid dynamics was used to investigate the blood flow fields of the implanted grafts and to calculate parameters that might be indicative of thrombosis. RESULTS Thrombosis was detected in 10 of 12 (83.3%) implanted ePTFE grafts, 5 in uncoated grafts and 5 in anti-CD34-coated grafts. Endothelial cell coverage was observed in both uncoated and anti-CD34-coated grafts. No obvious abnormalities in anastomotic stoma or blood coagulation state were observed. Computer-based local hemodynamic simulation showed the low flexibility of synthetic ePTFE grafts caused obvious coarctation. Local wall pressure, velocity and wall shear stress were much higher than in the contralateral normal vessel. CONCLUSIONS The patency of small-caliber ePTFE grafts for clinical use is impaired by early thrombosis due to mixed causes. Local hemodynamic disturbance was the most powerful predictor of early thrombosis. Decreasing local hemodynamic disturbance, improving the quality of anastomotic stoma, selecting reasonable anticoagulation strategies and promoting rapid endothelialization may increase the long-term patency of small-caliber vascular grafts.

Abstract
OBJECTIVE To compare the diagnostic validity of blood enzyme-linked immunospot assay (ELISpot), broncho-alveolar lavage (BAL) ELISpot and the tuberculin skin test (TST) in patients with pulmonary smear-negative tuberculosis (TB) in a country with high TB prevalence. DESIGN In a prospective, hospital-based study, 107 patients with suspected TB were tested simultaneously using blood and BAL ELISpot and TST. RESULTS Of 102 patients with active pulmonary TB, 36 (35.3%) were diagnosed with TB, while 66/102 (64.7%) had a non-TB diagnosis. The sensitivity and specificity for ELISpot on mononuclear cells from BAL fluid was respectively 94.4% (95%CI 81.9-98.5) and 78.1% (95%CI 66.6-86.5). The specificity of BAL ELISpot was significantly higher than that of blood ELISpot (P = 0.011). Compared with blood ELISpot and TST, BAL ELISpot was not significantly influenced by previous history of TB (OR 2.05, P > 0.05) or household contact with a patient with active TB (OR 2.41, P > 0.05). CONCLUSION ELISpot on BAL appears to be a more rapid and sensitive supplementary test than on blood for the diagnosis of active TB patients with a negative sputum smear in a developing country setting with high TB prevalence and access to bronchoscopy and ELISpot assay. However, the test's utility was limited by its moderate specificity.

Abstract
OBJECTIVES We aimed to explore the DNA methylation difference between lung cancer samples and non-cancer lung samples, and to investigate the role of DNA methylation in the mechanism of lung cancer development. Besides, we analyzed the transcriptional regulation network of DNA methylation and the miRNAs regulated by DNA methylation. This study provides a framework for DNA methylation in other tumors or diseases. MATERIALS AND METHODS DNA methylation and gene expression profiles used were obtained from Gene Expression Omnibus. Firstly, we identified differentially methylated genes (DMGs) by Student's t-test. Then we detected the biological processes and pathways changed in lung cancer by Gene Ontology (GO) and KEGG pathway enrichment analysis. The transcriptional factors in differential genes were identified and the microRNAs regulated by them were also obtained in TransmiR. RESULTS We obtained 108 DMGs between lung cancer samples and non-cancer samples. Besides development related biological processes and pathways were dramatically disordered. For the DMGs, we identified 11 transcriptional factors regulating them. Moreover, we screened out 21 relationships between DMGs and their transcriptional targets. Five microRNAs are reported to be regulated by DNA methylation genes. Finally a regulation network of DNA methylation was constructed. CONCLUSIONS DNA methylation participates in carcinogenesis at the transcriptional and post-transcriptional level. Aberrant DNA methylation will prevent its binding with the upstream regulatory proteins, inhibit the function of downstream target genes and regulate the expression of downstream miRNA, and consequently affect cell development, immunoresponse and apoptosis.

Abstract
BACKGROUND Isoflurane can increase pro-inflammatory cytokine interleukin (IL)-6 levels. However, the up-stream mechanism remains unknown. Nuclear factor-kappa B (NF-κB) promotes the generation of pro-inflammatory cytokines. We examined the effects of isoflurane and sevoflurane on the NF-κB signalling pathway and its association with IL-6 levels in cultured cells. METHODS H4 human neuroglioma cells (H4 cells), and mouse primary neurones and microglia were treated with 2% isoflurane or 4.1% sevoflurane for 6 h, for analysis of IL-6 and NF-κB. Pyrrolidine dithiocarbamate (an NF-κB inhibitor) or 2-deoxy-d-glucose (2-DG) (an inhibitor of glucose glycolysis) was applied 1 h before anaesthetic treatment. RESULTS Isoflurane or sevoflurane treatment increased the levels of IL-6 [isoflurane: 410% (54); sevoflurane: 290% (24)], the nuclear levels of NF-κB [isoflurane: 170% (36); sevoflurane: 320% (30)], and the transcription activity of NF-κB in H4 cells. Moreover, isoflurane enhanced the transcription activity of NF-κB in mouse microglia, but not primary neurones. Finally, pyrrolidine dithiocarbamate and 2-DG attenuated isoflurane-induced increases in IL-6 and NF-κB, and the transcription activity of NF-κB. CONCLUSIONS These studies in H4 cells suggest that the NF-κB signalling pathway could contribute to isoflurane or sevoflurane-induced neuroinflammation. This could lead to the targeted intervention of anaesthetic-induced neuroinflammation.

Abstract
Abstract
The type I transmembrane protein with epidermal growth factor and two follistatin motifs 2 (TMEFF2) is expressed mainly in brain and prostate. Expression of TMEFF2 is deregulated in a significant fraction of primary and metastatic prostate, suggesting a role in this disease. In fact, we have previously shown that TMEFF2 can function as a tumor suppressor in vitro, inhibiting monolayer and anchorage-independent cellular growth in HEK293T cells and sarcosine-induced cell migration and invasion in benign prostate epithelial RWPE-1 cells. However, the molecular mechanisms involved in the tumor suppressor phenotype of TMEFF2 are not clear. TMEFF2 has several biologically important features. The extracellular domain contains two follistatin domains and an epidermal growth factor-like (EGF) domain, while the transmembrane domain and short cytoplasmic tail have features resembling a G protein activating domain, suggesting that it may signal through a G protein. We hypothesize that the tumor suppressor activity of TMEFF2 is, at least in part, due to signaling mediated by the putative G protein activating domain. In order to test this hypothesis, here we investigate the role of TMEFF2 and a mutant lacking the cytoplasmic tail on cellular migration of prostate cancer cells, and begin analyzing the molecular mechanisms involved in this effect.
Our results demonstrate that overexpression of TMEFF2 in human prostate cancer cell line RWPE-2 causes about 60% decrease in cellular migration as assessed by wound-healing assays. Interestingly, we found that RWPE-2 cells overexpressing TMEFF2 have a defect in cell spreading on culture dishes (∼20% decrease) as well as on vitronectin-coated coverslips (∼30% decrease) and that this defect is accompanied by abolished focal adhesion and stress fiber formation. Moreover, the inhibition of TMEFF2 on cellular migration is dependent on its G protein activating domain as deletion of this domain rescues migration, spreading on vitronectin, and focal adhesion formation. The specific G protein pathway(s) involved in the anti-migratory effect of TMEFF2 is currently under investigation.
In summary, the data presented here indicate, for the first time, that the anti-migratory effect of TMEFF2 in human prostate cancer cells is mediated by its G protein activating domain. These results raise the possibility that TMEFF2 agonists may be used as therapeutic agents to mediate tumor suppression via this pathway.

Abstract
BACKGROUND Vitiligo is an acquired depigmentation autoimmune disorder that has been described as being associated with lower levels of 25-hydroxyvitamin D [25(OH)D]. Genetic variations within the vitamin D receptor (VDR) gene could lead to significant receptor dysfunction, and could further affect the formation of the biologically active 25(OH)D. Therefore, we hypothesized that VDR polymorphisms might be involved in vitiligo by affecting the formation of 25(OH)D. OBJECTIVES To evaluate the potential association between VDR polymorphisms and vitiligo susceptibility and the serum levels of 25(OH)D. METHODS We performed a hospital-based study of 749 patients with vitiligo and 763 matched controls. We investigated four VDR polymorphisms (FokI, BsmI, ApaI and TaqI) to determine whether they are associated with vitiligo susceptibility in the Chinese population. In addition, the levels of 25(OH)D were measured to evaluate possible associations between the VDR polymorphic variants and clinical and laboratory findings of vitiligo. RESULTS A significantly decreased risk of developing vitiligo was found to be associated with the BsmI-B, ApaI-A and TaqI-t alleles. According to the genotype distribution, 25(OH)D concentrations were significantly higher in patients carrying the FokI ff or ApaI AA genotypes compared with those carrying the FF or aa genotypes. Logistic regression analysis also showed a dose-response relationship between decreased risk of vitiligo and increased 25(OH)D levels in ApaI-A variant genotype carriers. CONCLUSIONS Our findings suggest that these VDR polymorphisms are associated with 25(OH)D levels and that there exists a genetic predisposition for vitiligo in the Chinese population.

Abstract
Promoting neural stem/progenitor cell (NSC/NPC) survival in the pro-apoptotic environment is critical to stem cell replacement for neurodegenerative disease therapy. Paeoniflorin (PF), one of the principal bioactive components in Paeoniae Radix, has been used widely in central nervous system (CNS) diseases treatment and serves as an antioxidant to protect neurons against oxidative stress. The present study investigated the protective effects of PF on NPC injury induced by hydrogen peroxide (H₂O₂). After challenge with 200 μM H₂O₂ for 2h, loss of cell viability and excessive apoptotic cell death were observed in cultured NPC, PF treatment conferred protective effects against the loss of cellular viability in a concentration-dependent manner. PF pretreatment also inhibited NPC apoptosis induced by H₂O₂ by reversing the decreased level of Procaspase-3 and balancing Bcl-2 and Bax expression. Furthermore, PF-mediated NPC protection was associated with an increase in phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt-1) phosphorylation in a time- and concentration-dependent manner. Selective inhibition of PI3K using LY294002 abolished PF-mediated phosphorylation of Akt-1 and NPC protection upon oxidative stress. These data suggest that PF-mediated NPC protection on H₂O₂ injury is reliant on the activation of the PI3K/Akt-1 pathway, giving insight to an essential role of PF in NPC protection.

Abstract
Prolonged use of chemical anthelmintics has been found to result in anthelmintic resistance and environmental issues, thereby limiting the application of these drugs in domestic animals and prompting interest in the study of plant extracts as alternative sources thereof. The aim of this study was to evaluate the in vitro effect of the essential oil (EO) of Artemisia lancea against the parasitic nematode Haemonchus contortus using egg hatch assay, larval development assay, and larval migration inhibition assay. The EO yield of extraction was 0.63% (w/w), and the major constituents were 1,8-cineole (34.56%) and camphor (16.65%). In the egg hatch assay, an inhibition greater than 99% was observed with the EO at 10 mg mL(-1) and the LC50 was 1.82 mg mL(-1). 1,8-Cineole demonstrated moderate ovicidal activity with a LC50 of 4.64 mg mL(-1), whereas camphor did not show enough activity to have its LC50 determined. In the larval development assay, the EO, 1,8-cineole, and camphor inhibited 93.6%, 65.2%, and 57% of larval development at 10 mg mL(-1) and exhibited dose-dependent responses with LC50 values of 1.66, 5.07, and 7.80 mg mL(-1), respectively. In the migration inhibition assay, the EO and 1,8-cineole at best inhibited 77% and 60.3% of larval migration at 10 mg mL(-1), respectively. Camphor showed low inhibition capacity, and its efficacy was not dose dependent. The results indicate that the in vitro anthelmintic activity of the EO of A. lancea may be associated with the additive action of the two major constituents, as well as other more minor terpenoid components.

Abstract
PURPOSE Gestational hypertension (GH) is a serious health hazard for pregnant women and fetuses. The incidence of GH involves many epidemiological, biochemical, and hemodynamic factors. METHODS The current study investigated the GH risk under the influence of epidemiological, biochemical, and hemodynamic factors, and designed corresponding GH risk evaluation methods and apparatus. RESULTS The evaluation method has 74.15% sensitivity and 81.84% specificity. The ROC area under the curve is 0.841. The apparatus automatically imports epidemiological, biochemical, and hemodynamic factors, and then expresses the GH risk as numbers, bar codes, and colors through logic array analysis. CONCLUSION The GH risk value can effectively give the risk level of GH. The GH risk barcode can improve the degree of automation of information storage, transmission, and identification in GH monitoring. The GH risk color can also improve the GH macro description.

Abstract
An analysis of the causes for iatrogenic diffusion of gynecological malignant tumors during their diagnosis and treatment, through clinical experience and a comprehensive review of both Chinese and international literatures was carried out. When a curettage, hysteroscopy or laparoscopy is performed, an iatrogenic diffusion of malignant tumors can be caused. Therefore this phenomenon needs to be prevented and reduced during the diagnosis and treatment of gynecological malignant tumors, and to improve the curative effect and survival times of tumor patients.
