Methods Thirty-six male mice were fed with standard food （SF） （n=9） and HFD （n=27）, respectively. Five weeks later, 9 mice fed with HFD were subjected to ZAG expression plasmid DNA transfection by liposome transfection method, and another 9 mice to negative control plasmid transfection. Two weeks later, serum ZAG level in the mice was assayed by Western blot, and the effects of ZAG over-expression on body weight, body fat, serum biochemical indexes, and adipose tissue of obese mice were evaluated. The mRNA expressions of fatty acid synthase （FAS） and hormone sensitive lipase （HSL） in liver tissue were deterlnined by reverse transcription-polymerase chain reaction. Results Serum ZAG level significantly lowered in simple HFD-fed mice in comparison to SF-fed mice （0.51±0.10 AU vs. 0.75±0.07 AU, P〈0.01）. Further statistical analysis demonstrated that ZAG level was negatively correlated with body weight （r =-0.56, P〈0.001）, epididymal fat mass （r=-0.67, P〈O. 001）, percentage of epididymal fat （r= 0.65, P〈0.001）, and increased weight （r= 0.57, P〈0.001） in simple SF- and HFD fed mice. ZAG over-expression in obese mice reduced body weight and the percentage of epididyreal fat. Furthermore, FAS mRNA expression decreased （P〈0.01） and HSL mRNA expression increased （P〈0.001） in the liver in ZAG over-expressing mice. Conclusions ZAG is closely related to obesity. Serum ZAG level is inversely correlated with body weight and percentage of body fat. The action of ZAG is associated with reduced FAS expression and increased HSL expression in the liver of obese mice.展开更多

The underlying molecular mechanisms and therapeutic effects of AZGP1 remain unknown in non-alcoholic fatty liver disease (NAFLD). AIM To explore the effects and potential mechanism of AZGP1 on NAFLD in vivo and in vitro. METHODS The expression of AZGP1 and its effects on hepatocytes were examined in NAFLD patients, CCl4-treated mice fed a high fat diet (HFD), and human LO2 cells. RESULTS AZGP1 levels were significantly decreased in liver tissues of NAFLD patients and mice. AZGP1 knockdown was found to activate inflammation;enhance steatogenesis, including promoting lipogenesis [sterol regulatory elementbinding protein (SREBP)-1c, liver X receptor (LXR), fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), and stearoyl CoA desaturase 1 (SCD)-1], increasing lipid transport and accumulation [fatty acid transport protein (FATP), carnitine palmitoyl transferase (CPT)-1A, and adiponectin], and reducing fatty acid β-oxidation [farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR)-α];accelerate proliferation;and reverse apoptosis in LO2 cells. AZGP1 overexpression (OV-AZGP1) had the opposite effects. Furthermore, AZGP1 alleviated NAFLD by blocking TNF-α-mediated inflammation and intracellular lipid deposition, promoting proliferation, and inhibiting apoptosis in LO2 cells. Finally, treatment with OV-AZGP1 plasmid dramatically improved liver injury and eliminated liver fat in NAFLD mice. CONCLUSION AZGP1 attenuates NAFLD with regard to ameliorating inflammation, accelerating lipolysis, promoting proliferation, and reducing apoptosis by negatively regulating TNF-α. AZGP1 is suggested to be a novel promising therapeutic target for NAFLD.展开更多

The plasma level of β2GPI was measured by ELISA and Western blotting, and anti-β2GPI antibody by ELISA. Lupus anticoagulant （LA） was assayed using the dilute Russell viper venom time. Deficiency of the major natural anticoagulants including protein C （PC）, protein S （PS）, antithrombin （AT） and thrombomodulin （TM） was excluded from the proband. A mutation analysis was performed by amplification and sequencing of the APOH gene. Wild type and mutant （c.112A〉G） APOH expression plasmids were constructed and transfected into HEK293T cells. The results showed that the thrornbin generation capacity of the proband was higher than that of the other family members. Missense mutation p.Lys38Glu in APOH gene and LA coexisted in the proband. The mutation led to β2GPI deficiency and thrombosis by impairing the protein production and inhibiting the platelet aggregation. It was concluded that the recurrent thrombosis of the proband is associated with the coexistence ofp.Lys38Glu mutation in APOH gene and LA in plasma.展开更多

METHODS： Peripheral blood samples were collected from 56 UC patients （34 males and 22 females, aged 43.5 years, range 21-66 years）, including 36 at active stage and 20 at remission stage, and 25 sex-and age-matched controls. The level of aβ2GP Ⅰ was measured by ELISA. The platelet activation markers, platelet activation complex- Ⅰ （PAC- Ⅰ ） and P-selectin （CD62P） were detected by flow cytometry. RESULTS： The A value for IgG aβ2GP Ⅰ in the active UC group was 0.61 ± 0.13, significantly higher than that in the remittent UC and control groups （0.50 ± 0.13 and 0.22 ± 0.14, P 〈 0.01）. There was a significant difference between the two groups （P 〈 0.01）. The A value for IgM aβ2GP Ⅰ in the active and remittent UC groups was 0.43 ± 0.13 and 0.38 ± 0.12, significantly higher than that in the control group （0.20 ± 0.12, P 〈 0.01）. However, there was no significant difference between the two groups （P 〉 0.05）. The PAC- Ⅰ positive rate for the active and remittent UC groups was 30.6% ± 7.6% and 19.6% ± 7.8% respectively, significantly higher than that for the control group （6.3% ± 1.7%,P 〈 0.01）. There was a significant difference between the two groups （P 〈 0.01）. The CD62P positive rate for the active and remittent UC groups was 45.0% ± 8.8% and 31.9% ± 7.8% respectively, significantly higher than that for the control group （9.2% ± 2.7%, P 〈 0.01）. There was a significant difference between the two groups （P 〈 0.01）. In the active UC group, the more severe the state of illness was, the higher the A value for IgG aβ2GP Ⅰ was, and the positive rate for PAC-Ⅰ and CD62P was positively correlated with the state of illness （Faβ2GP Ⅰ = 3.679, P 〈 0.05; FPAC-Ⅰ （%） = 5.346, P 〈 0.01; and FCD62P （%） = 5. 418, P 〈 0.01）. Meanwhile, in the same state of illness, the A value for IgG aβ2GP Ⅰ was positively correlated to the positive rates for PAC-Ⅰ and CD62P. CONCLUSION： aβ2GP Ⅰ level, platelet activation state and their relationship of them are closely correlated with the pathogenesis and development of UC.展开更多
