Abstract
Formaldehyde (FA) serves as a prevailing air pollutant, which has seriously threatened public health in recent years. Of all the known health effects, lung injury is one of the most severe risks. However, little is known about the circRNAs related molecular mechanism in the development of lung injury induced by FA. This study was designed to explore the potential roles of dysregulated circRNAs as well as its mechanism in FA-induced lung injury. In the present study, 24 male SD rats were exposed to formaldehyde (control, 0.5, 2.46 and 5 mg/m3) for 8 h per day for 8 weeks to induce lung injury. We used H&E staining to evaluate the histopathological changes of lung injury indifferent groups. The expression of circRNAs in lung tissue was detected by real-time PCR. Meanwhile, circRNA/miRNA/mRNA interaction networks were predicted by bioinformatics analysis. Our study revealed that formaldehyde exposure resulted in abnormal histopathological changes in lung tissues. Moreover, the expression of rno_circRNA_008646 was significantly higher in lung tissues of formaldehyde exposure rats than in control. Bioinformatics analysis showed that one potential target miRNA/mRNA for rno_circRNA_008646 was rno-miR-224/Forkhead Box I1 (FOXI1). Besides, luciferase report gene confirmed that there was targeted binding relationship between rno_circRNA_008646 and rno-miR-224, rno-miR-224 and FOXI1. Further verification experiments indicated that the expression of rno_circRNA_008646 was negatively correlated rno-miR-224, while it was positively correlated with FOXI1. JASPAR database showed transcription factor FOXI1 located in promotor of CF Transmembrane Conductance Regulator (CFTR). Both FOXI1 and CFTR were up-regulated in lung tissues after formaldehyde exposure. In conclusion, our findings suggested that formaldehyde may induce lung injury, and this may be caused by up-regulatedrno_circRNA_008646, which medicated rno-miR-224/FOXI1/CFTR axis.

Abstract
Although circular RNAs (circRNAs) can function as microRNAs (miRNAs) sponges to participate in spermatogenesis, little is known about the functions of circRNAs in testis exposed to formaldehyde. In this study, twenty-four male SD rats (6-8 weeks) were randomly assigned to four groups, including a control group, 0.5, 2.46, and 5 mg/m3 formaldehyde exposure groups, inhaling formaldehyde for eight consecutive weeks. The RT-qPCR was used to detect the expression of rno_circRNA_016194; the testicular injuries were observed by testicular histopathology. Our study illustrated up-regulated rno_circRNA_016194 was dose-dependent with formaldehyde. Simultaneously, the testicular histopathology showed an obvious damages in the 2.46 and 5 mg/m3 formaldehyde exposure rats. Combined with bioinformatics analysis, the rno-miR-449a-5p was predicted and verified that its expression decreased in the testis exposed to formaldehyde. Meanwhile, the testicular morphometry changes were contrary to the expression of rno_circRNA_016194 and consistent with rno-miR-449a-5p. Moreover, bioinformatics analysis also prompted the potential downstream target gene for rno_circRNA_016194/rno-miR-449a-5p was Atg4b, and Atg4b expression was up-regulated in rats exposed to formaldehyde verifying by Western blot. Collectively, the rno_circRNA_016194 might be involved in formaldehyde-induced male reproductive toxicity and become potential therapeutic targets for male occupational exposure to formaldehyde.

Abstract
Abstract
Background
Galectin-3 (Gal-3) is a clinical biomarker for risk of cardiovascular disease and a disease mediator forming a therapeutic target. However, the mechanism(s) that regulate cardiac expression of Gal-3 remains unknown. Activation of the sympatho-β-adrenergic system is a hallmark of heart disease, but the relationship of βAR activation and cardiac content of Gal-3 remains unknown.
Purpose
To determine the role of βAR activation in regulating cardiac Gal-3 level and the responsible mechanism focusing on the Hippo signalling pathway.
Methods
Wild-type and Gal-3 gene deleted (Gal3-KO) mice were used. To test the role of the Hippo pathway, we used transgenic (TG) mouse strains with cardiac overexpression of mammalian-20-like sterile kinase 1 (Mst1, mammalian orthology of Drosophila Hippo kinase) either in wild-type form (TG-Mst1) or dominative-negative kinase dead mutant form (TG-dnMst1). Effects of β-antagonist (isoprenaline, ISO) and antagonists were determined. We measured phosphorylation (Ser127) of YAP as a transcription co-regulator acting as the main signal output of the Hippo pathway.
Results
In wild-type mice, treatment with ISO led to a time- and dose-dependent increase in cardiac expression of Gal-3 (Fig. A) accompanied by elevated circulating Gal-3 levels (Fig. B). ISO treatment stimulated cardiac expression of Mst1 and YAP hyper-phosphorylation (i.e. inactivation, Fig. C), indicating activation of the Hippo signalling. These effects of ISO were inhibited by β-blockers (propranolol, Prop; carvedilol, Carv; Fig. D,E). Relative to non-TG controls, ISO-induced expression of Gal-3 was inhibited by 75% in TG-dnMst1 mice (inactivated Mst1), but exaggerated by 7-fold in TG-Mst1 mice (activated Mst1). Mst1-TG mice had a 45-fold increase in Gal-3 content, YAP hyper-phosphorylation and enhanced pro-fibrotic signaling. In Mst1-TG mice, whilst blood Gal-3 level was unchanged, treatment with ISO (6 mg, 2 days) evoked a marked increase in cardiac and blood Gal-3 levels. Using rat cardiomyoblasts, we showed that ISO-mediated Mst1 expression and YAP phosphorylation were PKA-dependent and that siRNA-mediated YAP knockdown led to Gal-3 upregulation. The role of Gal-3 in mediating ISO-induced cardiomyopathy was examined by treating wild-type and Gal3-KO mice with ISO (30 mg/kg, 7 days). ISO-treated wild-type mice had 8-fold increase in cardiac Gal-3, ventricular dysfunction, fibrosis, hypertrophy and activated inflammatory or fibrotic signalling. All these changes, except hypertrophy, were abolished by Gal3-KO.
beta-AR regulates galectin-3
Conclusion
βAR stimulation increases cardiac expression of Gal-3 through activation of the Hippo signalling pathway. This is accompanied by elevated circulating Gal-3 level. βAR antagonists inhibited βAR-Mst1 (Hippo) signalling and cardiac Gal-3 expression, actions likely contributing to the overall efficacy of β-blockers.

Abstract
A novel lipid micro-bubble (MB) loaded with docetaxel (DOC-MB) was investigated in a previous study. However, its anti-tumor effects and mechanism of action in combination with low-frequency ultrasound (LFUS) in vivo are still unclear. DOC-MBs containing 5.0 mg of DOC were prepared by lyophilization with modification via ultrasonic emulsification. Then, the effects of DOC-MBs combined with LFUS on tumor growth, proliferating cell nuclear antigen (PCNA) expression and cell apoptosis, as well as local DOC delivery, were investigated in H22 hepatocellular carcinoma (HCC)-bearing mice. Compared with the previously prepared DOC-MBs (1.6 mg of DOC loaded), the encapsulation efficiency (81.2% ± 3.89%) and concentration ([7.94 ± 0.04] × 10(9) bubbles/mL) of the DOC-MBs containing 5.0 mg of DOC were higher, but the bubble size (1.368 ± 0.004 μm) was smaller. After treatment with the DOC-MBs and LFUS, the H22 HCC growth inhibition rate was significantly increased, PCNA expression in tumor tissue was significantly inhibited and local release of DOC was induced. In conclusion, new DOC-MBs containing 5.0 mg of DOC were successfully prepared with a high encapsulation efficiency and superior bubble size and concentration, and their combination with LFUS significantly enhanced the anti-tumor effect of DOC in H22 HCC-bearing mice by inhibiting tumor cell proliferation and increasing local drug delivery.

Abstract
PURPOSE To investigate the distributions of HLA-B alleles and estimate their associations with idiopathic male infertility in Chinese Han population. METHODS Polymerase chain reaction-sequence-based typing (PCR-SBT) method was used for DNA typing at HLA-B locus in 109 patients with idiopathic male infertility and 152 healthy controls in male Han population of Shaanxi Province, situated in northwestern China. RESULTS In total, we detected 45 HLA-B alleles in idiopathic infertile patients, 48 HLA-B alleles in control subjects. However, no significant differences of these allelic frequencies were found between the infertile patients and the controls. CONCLUSION HLA-B gene was unlikely a major risk factor of idiopathic male infertility in this sample population. As different populations have different HLA polymorphisms, investigation of the relationship of other HLA genes and idiopathic male infertility with larger sample size, is warranted in the future.

Abstract
Immobilization of the anticoagulative or antithrombogenic biomolecule has been considered as one of the important methods to improve the blood compatibility of artificial biomaterials. In this study, a novel immobilization reaction scheme was utilized to incorporate O-butyrylchitosan (OBCS) onto the activated glass surface with an aim to develop an anticoagulative substrate. Activation of the glass surface was carried out by silanization and then OBCS was grafted to the silanized surface via a radiation grafting technique. The OBCS-grafted glass surfaces were characterized by electron spectroscopy for chemical analysis (ESCA) and atomic force microscopy (AFM). The blood compatibility of the OBCS-grafted glass was evaluated by platelet rich plasma (PRP) contacting experiments and protein adsorption experiments in vitro. These results have demonstrated that the surface with immobilized OBCS shows much less platelet adhesive and fibrinogen adsorption compared to the control surface. Therefore, the novel reaction scheme proposed here is very promising for future development of an anticoagulative glass substrate.
