Academic Journal of Second Military Medical University 2011;32(1):37-39
Objective: To investigate the expression of angiopoietin-related growth factor (AGF) in obese patients and its relationship with body mass index(BMI), waist circumference(WC), waist-hip ratio(WHR), blood glucose(FBG), plasma insulin(FINS) levels, and HOMA-insulin resistance index(HOMA-IR). Methods: Plasma AGF levels were assayed by ELISA in 40 patients with obesity and 40 normal controls. The relationship of AGF level with BMI, WC, WHR, HbA 1c, blood lipids, FBG, FINS, and HOMA-IR was also analyzed. Results: AGF levels in patients with obesity were significantly increased compared with that in the control group ([177.55±74.09] ng/ml vs [122.37±66.91] ng/ml, P<0.05). We also found that AGF level was positively correlated with Triglyceride(TG), FINS and HOMA-IR(r=0.325, P<0.05; r = 0.451, P<0.01; r = 0.483, P<0.01); and was negatively correlated with high-density lipoprotein cholesterol(HDL, r= -0.529, P<0.01). Multiple regression analysis showed that HDL, BMI and FINS were the factors influencing AGF levels. Binomial Logistic regression analysis indicated that AGF level was positively correlated with obesity after adjusting sex, age, total cholesterol (TC), TG, HDL and low-density lipoprotein cholesterol (LDL) (OR>1). Conclusion: The change of AGF level is associated with the metabolism disorder in obese patients, and it may also contribute to the pathogenesis of obesity.

3.Thrombin and angiogenesis of cancer--review.
Journal of Experimental Hematology 2006;14(1):197-200
Thrombin is the most important factor in hemostasis. In recent years, it has been found that thrombin is a potent mitogen capable of inducing cellular functions. Therefore, it is proved to be of importance in promoting the growth, metastasis and angiogenesis of cancer. Anticoagulant therapy not only reduce the characteristic hypercoagulability of cancer, but also inhibits growth and metastasis of cancer, and alters the fundamental biology of cancer. In this paper thrombin and its receptor, relationship of thrombin and its receptor with cancer growth, metastasis and angiogenesis, the mechanisms of thrombin influence on cancer angiogenesis, as well as application prospects on anti-angiogenesis and anti-coagulation therapy were reviewed.

Objective To investigate the effects of family allergic history and dermatophagoides farina on the expressions of Th1/Th2 cytokine of cord blood and allergic disorders in infancy.Methods Ten mil cord blood were obtained from 34 neonates which 17 cases had family allergic history and 17 cases didn′t have.Cord blood mononuclear cells(CBMC) were isolated by gradient centrifugation with Ficoll and were cultured with phytohemagglutinin(PHA) or dermatophagoides farina for 48 hours in vitro.The expressions of interleukin(IL-4) and interferon(IFN-?) of the culture supernatant were detected by enzyme-linked immunosorbent assay(ELISA).Two groups were visited with telephone or clinical service every 1 or 2 months in 1 year follow-up survey.Results In no stimulation,the expressions of IL-4 of family allergic history and no family allergic history were(11.35?1.80) ng/L and(11.0?1.50) ng/L,respectively,there was no significant difference.The expressions of IFN-? were(9.55?1.47) ng/L and(10.19?1.37) ng/L,respectively,there was no significant difference also.In PHA stimulation,the expressions of IL-4 were(43.45?4.57) ng/L and(37.58?3.41) ng/L,respectively,there was significant difference.The expressions of IFN-? were(72.61?25.40) ng/L and(65.84?29.96) ng/L,respectively,there was no significant diffe-rence.In low density dermatophagoides farina stimulation,the expressions of IL-4 were(40.54?3.64) ng/L and(37.17?2.60) ng/L,respectively,which had significant difference.The expressions of IFN-? were(35.30?2.73) ng/L and(40.55?1.85) ng/L,respectively,which had significant difference.In high density dermatophagoides farina stimulation,the expressions of IL-4 were(43.50?3.19) ng/L and(39.55?4.13) ng/L,respectively,which had significant difference.The expressions of IFN-? were(39.40 ?5.21) ng/L and(40.94?2.96) ng/L respectively,which had no significant difference.Allergic diseases were happened in 7 cases of 13 cases with family allergic history and in 2 cases of 15 cases without family allergic history in 1 year follow-up except lost follow-up cases.There were significant difference in 2 groups.Conclusions Th2 cells of cord blood are relative dominant in neonates having family allergic history.Th2 cells relative dominant are more obvious in dermatophagoides farina stimulation.The neonates having family allergic history have a tendency to get allergic diseases in childhood.

Objective To study the inflammation and expression of myosin light chain kinase(MLCK) through establishing acute lung injury animal model of mice induced by lipopolysacchride(LPS), and approach the role of MLCK in the mechanism of acute lung injury.Methods Twenty female BALB/c mice were randomly divided into LPS group(n=10) and control group(n=10).The BALB/c mice of LPS and control groups were induced by 30 ?L 0.9% NaCl via intranasal instillation,while only LPS group was treated with LPS(20 ?g/each mice).The pathology,wet/dry lung weight ratio and the total cell quantitation in bronchoalveolar lavage fluid(BALF)were compared between these two groups.Furthermore,immunohistochemistry assays were used to determine the status of MLCK expression in the lung.And RT-PCR was adopted to determine the status of MLCKmRNA in the lung. Results Compared with the control group,the LPS group showed more serious pulmonary hemorrhage,edema and infiltration of neutrophils, significantly increased water content in the lungs and total cell quantitation in BALF(P

Objective To study the effect of montelukast(MK)and dexamethasone(Dex)on inflammation of asthma.Methods Asthma model was established and treated with MK or Dex.Bronchoalveolar lavage fluid(BALF) and histopathologic change were observed,IL-5mRNA of lung and bone marrow cells were detected by in situ hybridization,IL-5 immunoreactive cells by immunohistochemistry,and CD34+ and CD3+ of bone marrow cells by flow cytometry. ResultsCompared with asthma group,the number of total cells and eosinophils in BALF of MK group and Dex group were significantly decreased(P0.05). Conclusion MK and Dex can well inhibit airway inflammation and expression of IL-5mRNA in lung and bone marrow cells,though MK may be inferior to Dex in some aspects.The combined treatment of leukotriene receptor antagonist and glucocorticosteroid may be a new direction for asthma.

Objective To investigate the correlation of the anti-cardiolipin(aCL) antibodies and anti-β2 glycoprotein Ⅰ(anti-β2GPI) antibodies in missed abortion women.Methods Fourteen patients diagnosed missed abortion were chose as trial group,while 20 normal females received induced abortion in the same time as control group.Chemiluminescence method was used to measure the serum levels of IgG/IgM aCL and IgG/IgM anti-β2GPI antibodies in the two groups.Results The median levels of serum IgM aCL antibodies and serum IgM anti-β2GPI antibodies in trial group were significantly higher than those of control group(21.3(2.2-39.4)KU/L vs.6.0(1.5-10.7) KU/L,11.9(1.2-25.4) KU/L vs.1.9(1.1-4.0) KU/L;u=2.031,2.912;P <0.05).There were no significant differences in terms of the levels of serum IgG aCL antibodies and serum IgG anti-β2GPI antibodies between trial group and control group (P>0.05).Conclusion There is correlation between IgM aCL as well as IgM anti-β2GPI antibodies and missed abortion,so in reducing the incidence of missed abortion,early and dynamic detection of anti-cardiolipin and anti-β2 glycoprotein I antibodies in childbearing women has a certain clinical significance.
