Abstract
PURPOSE Papillary thyroid carcinoma (PTC) represents the most common subtype of thyroid cancer (TC). This study was set out to explore the potential effect of CHD1L on PTC and type 2 diabetes mellitus (T2DM). METHODS We searched for T2DM susceptibility genes through the GWAS database and obtained T2DM-related differentially expressed gene from the GEO database. The expression and clinical data of TC and normal samples were collated from the TCGA database. Receiver operating characteristic (ROC) curve analysis was subsequently applied to assess the sensitivity and specificity of the CHD1L for the diagnosis of PTC. The MCP-counter package in R language was then utilized to generate immune cell score to evaluate the relationship between CHD1L expression and immune cells. Then, we performed functional enrichment analysis of co-expressed genes and DEGs to determine significantly enriched GO terms and KEGG to predict the potential functions of CHD1L in PTC samples and T2DM adipose tissue. RESULTS From two genes (ABCB9, CHD1L) were identified to be DEGs (p < 1 * 10-5) that exerted effects on survival (HR > 1, p < 0.05) in PTC and served as T2DM susceptibility genes. The gene expression matrix-based scoring of immunocytes suggested that PTC samples with high and low CHD1L expression presented with significant differences in the tumor microenvironment (TME). The enrichment analysis of CHD1L co-expressed genes and DEGs suggested that CHD1L was involved in multiple pathways to regulate the development of PTC. Among them, Kaposi sarcoma-associated herpesvirus infection, salmonella infection and TNF signaling pathways were highlighted as the three most relevant pathways. GSEA analysis, employed to analyze the genome dataset of PTC samples and T2DM adipose tissue presenting with high and low expression groups of CHD1L, suggests that these differential genes are related to chemokine signaling pathway, leukocyte transendothelial migration and TCELL receptor signaling pathway. CONCLUSION CHD1L may potentially serve as an early diagnostic biomarker for PTC, and a target of immunotherapy for PTC and T2DM.

Abstract
Acute lung injury (ALI)/Acute respiratory distress syndrome (ARDS) is a very dangerous disease. The purpose of this study was to investigate the effects of fibrogrowth factor-2 (FGF-2) on lipopolysaccharide (LPS)-induced lung injury and its mechanisms. C57/BL6 mice were used in the study and LPS was used to construct the ALI/ARDS model. In addition, human normal lung epithelial cell line BEAS-2B was cultured to investigate the effect of FGF-2 on the lung and its mechanism of action in vitro. FGF-2 significantly reduced wet/dry weight ratio of mice, the number of cells and inflammatory factors in BALF, and MPO activity in lung tissue. In addition, FGF-2 also reduced the level of oxidative stress in mouse lung tissue. In vitro, FGF-2 effectively reduced LPS-induced inflammatory and apoptotic levels of BEAS-2B cells and increased the activity of the PI3K/Akt signaling pathway. However, LY294002, an inhibitor of the PI3K/Akt signaling pathway, alleviated the protective effect of FGF-2 on lung tissue. Therefore, FGF-2 attenuated inflammation, oxidative stress and apoptosis in alveolar epithelial cells by activating the PI3K/Akt signaling pathway.

Abstract
Podophyllotoxin (PPT) is a kind of lignans extracted from the roots and stems of the genus Podophyllum from the tiller family, and it has been widely used in the treatment of condyloma acuminatum, multiple superficial epithelioma in the clinics. However, PPT has been reported to be toxic and can cause liver defects and other organ poisoning. In addition, emerging evidences also indicate that PPT has reproductive toxicity and causes female reproduction disorders. In this study, we used fertilized oocytes and tried to explore the effects of PPT on the early embryonic development with the mouse model. The results showed that exposure to PPT had negative effects on the cleavage of zygotes. Further analysis indicated that PPT could disrupt the organization of spindle and chromosome arrangement at the metaphase of first cleavage. We also found that PPT exposure to the zygotes induced excessive reactive oxygen species (ROS), suggesting the occurrence of oxidative stress. Moreover, in the PPT-exposed embryos, there was positive γH2A.X and Annexin-V signals, indicating that PPT induced embryonic DNA damage and early apoptosis. In conclusion, our results suggested that PPT could affect spindle formation and chromosome alignment during the first cleavage of mouse embryos, and its exposure induced DNA damage-mediated oxidative stress which eventually led to embryonic apoptosis, indicating the toxic effects of PPT on the early embryo development.

Abstract
Interleukin‐27 (IL‐27) gene polymorphisms are linked to infectious disease susceptibility and IL‐27 plasma level is associated with HIV infection. Therefore, we aimed to investigate the association between IL‐27 polymorphisms and susceptibility to HIV infection and disease progression. A total of 300 patients with HIV infection (48 long‐term nonprogressors and 252 typical progressors) and 300 healthy controls were genotyped for three IL‐27 polymorphisms, rs17855750, rs181206, rs40837 which were performed by using multiple single nucleotide primer extension technique. Significant association was found between IL‐27 rs40837 polymorphisms with susceptibility to HIV infection (AG vs AA: adjusted OR = 1.60, 95% CI, 1.11‐2.30, P = 0.012; AG+GG vs AA: adjusted OR = 1.44, 95% CI, 1.02‐2.03, P = 0.038) and disease progression (LTNP: AG vs AA: adjusted OR = 2.33, 95% CI, 1.13‐4.80, P = 0.021; TP: AG vs AA: adjusted OR = 1.50, 95% CI, 1.04‐2.24, P = 0.030). Serum IL‐27 levels were significantly lower in cases compared to controls (P < 0.001). There were lower serum IL‐27 levels in TPs than in LTNPs (P < 0.001). We further found that LTNPs with rs40837 AG or GG genotype had lower serum IL‐27 levels than with AA genotype (P < 0.05). The CD4+T counts in cases were significantly lower than controls (P < 0.001). In contrast, individuals with rs40837 AG genotype had lower CD4+T counts than with AA genotype in cases (P < 0.05). In addition, CD4+T counts in TPs were significantly lower than LTNPs (P < 0.001). IL‐27 rs40837 polymorphism might influence the susceptibility to HIV infection and disease progression probably by regulating the level of serum IL‐27 or the quantity of CD4+T.

Abstract
The clinical significance of thymosin β4 (Tβ4) expression in bladder transitional cell carcinoma (BTCC) remains unclear. The present study assessed the relationship between the expression of Tβ4 protein and the clinicopathological features, as well as the prognosis of bladder cancer patients. Tβ4 protein expression in 24 normal bladder and 138 primary BTCC tissue specimens was detected by immunohistochemistry, and the association of this expression with BTCC clinicopathological features and recurrence as well as patient survival was analyzed. Tβ4 expression was significantly stronger in BTCC patients than in normal volunteers. The expression of Tβ4 was significantly associated with differentiation capability, tumor stage and lymph node metastasis (P = 0.025, 0.043, and 0.039, respectively). Moreover, Tβ4 expression was positively correlated with integrin-linked kinase (ILK) and β-catenin expression (P = 0.042, 0.031, respectively) and inversely correlated with E-cadherin expression (P = 0.022). In the present cohort of bladder cancer patients, Tβ4 expression was found to be a predictor of poor survival (P < 0.05); however, high Tβ4 expression exhibited unfavorable prognostic value for recurrence. These data suggested that Tβ4 is correlated with the pathogenesis of BTCC. In addition, the patients with higher Tβ4 expression had a shorter survival.

Abstract
OBJECTIVE To investigate the correlation of the single nucleotide polymorphisms (SNPs) rs12009, rs1140763 and rs16927997 in the 3'-untranslated region (3'UTR) of the glucose-regulated protein 78 (GRP78) gene with the risk of male asthenozoospermia (AZS). METHODS We included 400 AZS patients in the AZS group and another 400 fertile men as normal controls. Using the SNaPshot technique, we genotyped the rs12009, rs1140763 and rs16927997 polymorphisms in the 3'UTR of the GRP78 gene in all the male subjects and analyzed the association of the three SNPs with AZS. RESULTS The percentage of progressively motile sperm was significantly lower in the AZS group than in the normal controls ([20.09 ± 8.18] % vs [57.16 ± 13.45] %, P <0.01). Three genotypes of CC, CT and TT and 2 alleles of C and T were found in rs12009 and rs1140763 of the GRP78 gene, and another three genotypes of GG, GA and AA and two alleles of G and A were observed in rs16927997. There were no statistically significant differences between the control and AZS groups in the frequencies of the C and T alleles in rs12009 (44.3% vs 47.3% and 55.7% vs 52.7%, P >0.05) or rs1140763 (50.0% vs 52.0% and 50.0% vs 48.0%, P >0.05) or those of the G and A alleles in rs16927997 (6.0% vs 4.4% and 94.0% vs 95.6%, P >0.05), nor in the genotypes and allele frequencies of the 3 polymorphisms (P >0.05). Furthermore, three haplotypes of C-C-A, T-C-G and T-T-A were observed in the male subjects but showed no evident correlation between the AZS and normal control groups. CONCLUSIONS The polymorphisms in the 3'UTR of the GRP78 gene are not correlated with the risk of male asthenozoospermia.

Abstract
BACKGROUND The aim of this study was to investigate the effects of procalcitonin on the lipopolysaccharide (LPS)-induced changes in human leucocytes and porcine isolated coronary artery. METHODS Using flow cytometry, changes in forward scatter and intracellular calcium in human neutrophils and monocytes were determined after exposure to procalcitonin, calcitonin gene-related peptide (CGRP), LPS, and the known chemoattractants formylated methionine-leucine-phenylalanine (fMLP) and interleukin-8 (IL-8). In porcine isolated coronary artery, the effects of procalcitonin were evaluated using the contractile function change and the release of TNFalpha. RESULTS In human neutrophils and monocytes, procalcitonin (100 nM), but not CGRP, increased forward scatter and the expression of surface markers (CD16 and CD14, respectively) in a similar manner to 10 microg ml(-1) LPS. Procalcitonin, but not CGRP, also increased the proportion of cells exhibiting an increase in intracellular calcium ions similar to that produced by fMLP and IL-8. Acute exposure of the coronary artery to procalcitonin produced a small, endothelium-independent relaxation (approximately 15% of constrictor tone), but failed to modify subsequent relaxations to CGRP. After 16 h exposure, procalcitonin (100 nM) increased TNFalpha release from the coronary artery equivalent to 70% of that produced by LPS, but did not modify the inhibitory effect of LPS (100 microg ml(-1)) on contractile responses. CONCLUSIONS Procalcitonin has a proinflammatory effect on human leucocytes and porcine coronary artery, but it is not capable of modulating LPS-induced changes in vascular responsiveness in vitro.

Abstract
The p73 protein is a transcription factor and member of the p53 protein family that expresses as a complex variety of isoforms. DeltaNp73alpha is an N-terminally truncated isoform of p73. We found that DeltaNp73 protein is upregulated in human gastric carcinoma suggesting that DeltaNp73 may play an oncogenic role in these tumors. Although it has been shown that DeltaNp73alpha inhibits apoptosis and counteracts the effect of chemotherapeutic drugs, the underlying mechanism by which this p73 isoform contributes to chemotherapeutic drug response remains to be explored. We found that DeltaNp73alpha upregulates MDR1 mRNA and p-glycoprotein (p-gp), which is involved in chemotherapeutic drug transport. This p-gp upregulation was accompanied by increased p-gp functional activity in gastric cancer cells. Our data suggest that upregulation of MDR1 by DeltaNp73alpha is mediated by interaction with p53 at the MDR1 promoter.

Abstract
BACKGROUND Prolonged incubation of porcine isolated coronary artery (PCA) to lipopolysaccharide (LPS) causes a moderate reduction in vessel constrictive responsiveness. This has been attributed mainly to the induction of nitric oxide synthase (NOS). We aimed to investigate the role of induction of cyclo-oxygenase (COX) and expression of endothelin receptor 1-A (ET1(A)) in modulating the vascular responses of PCA in vitro. METHODS Segments of PCA were exposed to 100 microg ml(-1) LPS overnight. L-Arginine 0.4 mM was included in the medium in some preparations to examine the influence of intracellular nitric oxide, and the influence of extracellular donor sodium nitroprusside (SNP) was also examined in separate experiments. After overnight incubation, the contractile function of the artery was evaluated by the isometric tension recording test. The non-selective NOS inhibitor (L-NAME), non-selective COX inhibitor (indomethacin), COX-1 inhibitor (FR 122047), COX-2 inhibitor (NS 398), and ET1(A) receptor antagonist (FR 139317) were added into the organ bath 30 min before eliciting contractile responses to KCl or U46619 separately or in combinations. Vascular relaxations to 10 nM Substance P (SP) were also assessed. RESULTS L-Arginine did not potentiate the effects of LPS. SNP caused a quantitatively larger reduction in the responsiveness to KCl and U46619 compared with 100 microg ml(-1) LPS. Post exposure to a combination of indomethacin and FR 139317, indomethacin or NS 398 alone enhanced the inhibitory effects of LPS, but FR 122047 or FR 139317 alone failed to modify the responses to LPS. L-NAME fully reversed the changes induced by LPS combined with indomethacin and NS398. In terms of the relaxation by SP, LPS failed to change the magnitude; none of the agents used affected the response except L-NAME which abolished it. CONCLUSION NOS and COX-2 are both activated by overnight exposure to LPS in vascular smooth muscle from PCA in vitro. The prostanoid produced by COX-2 functionally antagonizes the effects of induction of NOS.

Abstract
We measured a dose-response relationship for induction of neoplastic transformation by 6 MeV alpha particles and 137Cs gamma rays in REC:myc and REC:ras cells, that is, rat embryo cells (REC) transfected with the c-myc or the Ha-ras oncogenes. The 6 MeV alpha particles simulated 222Rn emissions for risk assessment relative to low-LET radiations. The dose of gamma rays was approximately twice that of alpha particles for a neoplastic transformation frequency of 10(-3). The survival of the REC cells containing oncogenes was comparable to that of the commonly used C3H 10T1/2 cells for the same dose, but the former were more refractory to radiation-induced neoplastic transformation. Neoplastic transformation frequency measured in REC cells was 3 times lower than those typically measured in C3H 10T1/2 cells at a gamma-ray dose of 6 Gy, and 5-10 times lower at an alpha-particle dose of 3 Gy.

Abstract
The New WHO Trachoma Grading System is found feasible in China by an epidemiological survey of trachoma using the two trachoma grading systems, the new WHO system and the Chinese conventional system, especially for large scale examination and treatment and for epidemiological survey. However, the New System regards the proportion of active trachoma amongst children under 10 years as the index of the scope and severity of the disease in a community, while the authors opine that the trachoma prevalence in teenagers, especially in middle school students, better reflects the situation of trachoma infection in a Chinese community.
