Methods The incidence of ozone exposure combined with heat wave was simulated in the Shanghai Meteorological and Environmental Animal Exposure System（Shanghai-METAS）. A total of 64 Apo E-/-mice, matched by weight, were randomly divided into 8 groups and exposed to heat wave conditions or ozone. The levels of creatine kinase（CK）, D-lactate dehydrogenase（D-LDH）, intercellular adhesion molecule 1（sICAM-1）, tumor necrosis factor alpha（TNF-α）, nitric oxide（NO）, endothelin-1（ET-1）, D-dimer（D2 D）, plasminogen activator inhibitor-1（PAI-1） and blood lipid in plasma and heat shock protein-60（HSP60）, hypoxia inducible factor 1 alpha（HIF-1α）, interleukin-6（IL-6）, C-reactive protein（CRP）, superoxide dismutase（SOD）, and malondialdehyde（MDA） in hearts were measured after exposure. Results The levels of all indicators, except for SOD, increased with the ozone-only exposure. However, cardiac damage was most significant when the heat wave conditions were combined with severe ozone exposure. Moreover, the levels of CK, D-LDH, NO, PAI-1, sICAM-1, and TNF-α in plasma increased significantly（P 〈 0.05）, and the contents of HSP60, HIF-1α, CRP, and MDA in hearts increased considerably（P 〈 0.05）, but the activity of SOD decreased significantly. In addition, the levels of four blood lipid items remarkably increased（except the level of HDL-C which decreased significantly） with ozone exposure. Conclusion A short-term exposure to a heat wave and ozone causes severe toxic effects on the heart. Cardiac damage was most significant under combined heat wave and severe ozone exposure simulations.展开更多

文摘Background:EBV-miR-BARTs exhibit significant relevance in epithelial tumors,particularly in EBVassociated gastric and nasopharyngeal cancers.However,their specific mechanisms in the initiation and progression of gastric cancer remain insufficiently explored.Material and Methods:Initially,EBV-miRNA-BART6-5p and its target gene SMAD4 expression were assessed in EBV-associated gastric cancer tissues and cell lines.Subsequent transfection induced overexpression of EBV-miRNA-BART6-5p in AGS and MKN-45,and downregulation in EBVpositive cells(SUN-719).The subsequent evaluation aimed to observe their impact on gastric cancer cell proliferation,migration,and glycolytic processes,with the TGF-β/SMAD4 signaling pathway value clarified using a TGF-βinhibitor.Results:EBV-miRNA-BART6-5p exhibits pronounced upregulation in EBV-associated gastric cancer tissues and EBV-positive cells,while its target gene SMAD4 demonstrates downregulated expression.Upregulation of it can promote the proliferation and migration of gastric cancer cells.Additionally,We found EBV-miRNA-BART6-5p promotes glycolysis of gastric cancer cells.Inhibition of the TGF-β/SMAD4 signaling pathway resulted in suppressed proliferation and migration of gastric cancer cells,concomitant with a diminished glycolytic capacity.Conclusion:In this study,we found that EBV-miRNA-BART6-5p can target SMAD4,effectively increasing glycolysis in gastric cancer cells by regulating the TGF-β/SMAD4 signaling pathway,thereby enhancing the proliferation and metastasis of gastric cancer cells.Our findings may offer new insights into the metabolic aspects of gastric cancer.

文摘Objective: To establish and evaluate a mouse model of bronchial asthma with Yin deficiency syndrome. Methods: The mouse model of bronchial asthma with Yin deficiency syndrome was established by the treatment with injecting ovalbumin(OVA) two times to sensitize, inhaling OVA 14 times to stimulate, and using thyroxin through lavage during late stimulation. This model was evaluated through body weight, asthmatic behaviors, respiratory function, autonomous activity, lung pathology, and pulmonary fluid clearance. Results: OVA combined with thyroxin was an appropriate method to induce the mouse model with increased food and water intake, autonomous activity, asthmatic behaviors score, and respiratory rate, decreased body weight, tidal volume, and wet/dry ratio of lung, and changed with pathology of lung tissue. The changes of the above mentioned parameters indicated that the model was the bronchial asthma with Yin deficiency syndrome. Conclusion: The OVA combined with thyroxin is a good pattern to establish a mouse model of bronchial asthma with Yin deficiency syndrome successfully, which can highly simulate the clinical symptoms of this disease.

文摘Objective To discuss the cardiac toxicities of a heat waves and ozone exposure on cardiovascular diseases（CVDs） and explore a possible mechanism. Methods The incidence of ozone exposure combined with heat wave was simulated in the Shanghai Meteorological and Environmental Animal Exposure System（Shanghai-METAS）. A total of 64 Apo E-/-mice, matched by weight, were randomly divided into 8 groups and exposed to heat wave conditions or ozone. The levels of creatine kinase（CK）, D-lactate dehydrogenase（D-LDH）, intercellular adhesion molecule 1（sICAM-1）, tumor necrosis factor alpha（TNF-α）, nitric oxide（NO）, endothelin-1（ET-1）, D-dimer（D2 D）, plasminogen activator inhibitor-1（PAI-1） and blood lipid in plasma and heat shock protein-60（HSP60）, hypoxia inducible factor 1 alpha（HIF-1α）, interleukin-6（IL-6）, C-reactive protein（CRP）, superoxide dismutase（SOD）, and malondialdehyde（MDA） in hearts were measured after exposure. Results The levels of all indicators, except for SOD, increased with the ozone-only exposure. However, cardiac damage was most significant when the heat wave conditions were combined with severe ozone exposure. Moreover, the levels of CK, D-LDH, NO, PAI-1, sICAM-1, and TNF-α in plasma increased significantly（P 〈 0.05）, and the contents of HSP60, HIF-1α, CRP, and MDA in hearts increased considerably（P 〈 0.05）, but the activity of SOD decreased significantly. In addition, the levels of four blood lipid items remarkably increased（except the level of HDL-C which decreased significantly） with ozone exposure. Conclusion A short-term exposure to a heat wave and ozone causes severe toxic effects on the heart. Cardiac damage was most significant under combined heat wave and severe ozone exposure simulations.

文摘[Objectives]To explore the protective effects of Zuogui Pill on ^(60)Co-γ-ray-induced premature aging of rats based on phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR)signaling pathway.[Methods]Sixty sexually mature female SD rats were irradiated with ^(60)Co-γ-ray(6.0 Gy,LD 40)for 24 h at one time.These rats were randomly divided into model group,Progynova group[0.18(g·kg)/d],Progynova[0.09(g·kg)/d]+Zuogui Pill high dose[23.625(g·kg)/d)]group,Zuogui Pill high dose[23.625(g·kg)/d)]group,Zuogui Pill medium dose[9.45(g·kg)/d)]group and Zuogui Pill low dose[4.725(g·kg)/d]group.The administration(once a day)lasted 21 d.The rat serum[follicle-stimulating hormone(FSH),luteinizing hormone(LH)and estradiol(E_(2))]were detected by Enzyme-linked immunosorbent assay(ELISA).The morphological changes of ovary were observed by hematoxylin-eosin(HE)staining.The apoptosis rate of granulosa cells was detected by terminal deoxynucleotidyl transferase(TdT)-mediated dUTP nick-end labeling(TUNEL).The protein expression of phosphorylated(p)-PI3K,p-Akt,p-mTOR,B-cell lymphoma-2(Bcl-2),and Bcl-2-associated X protein(Bax)in ovarian tissues were detected by Western blot.[Results]Compared with the normal group,the model group showed significant increase in the serum FSH(P<0.01),significant decrease in serum E_(2)(P<0.05),and decrease in the number of early follicles and luteum in the ovary(P<0.01).Besides,the apoptosis rate of granulosa cells increased significantly(P<0.01);the expression of p-PI3K,p-Akt,p-mTOR and Bcl-2 in ovarian tissue decreased significantly,while the expression of Bax increased significantly(P<0.01).Compared with the model group,the number of early follicles in the ovary increased and the apoptosis rate of granulosa cells decreased after intervention in each administration group.In addition,the protein expressions of p-PI3K,p-Akt,p-mTOR and Bcl-2 increased,while the expression of Bax decreased,especially in Progynova+Zuogui Pill high dose group,the differences were statistically significant(P<0.05,P<0.01).[Conclusions]Zuogui Pill may protect the radiation-injured ovary through activating the expression of PI3K/Akt/mTOR protein in ovarian tissue,increasing the amount of Bcl-2 protein and inhibiting the expression of Bax protein.
