Aim To study the effect of IL-1β on pro-tein expression of vascular endothelial growth factor in glioma cells and plasma membrane microcapsule struc-ture protein caveolin-1 and plasma membrane vesicles in brain microvascular endothelial cells, and prelimi-narity discuss the possible mechanism of IL-1β opening blood tumor barrier. Methods The tumor barrier mod-el was established by transwell in vitro. The effect of IL-1β on the expression of VEGF in glioma cells and caveolin-1 in brain microvascular endothelial cells was dynamically monitored by Western blot. TEM was used to observe the number of plasma membrane vesicles of brain microvascular endothelial cells. Sodium fluores-cein leakage test was used to assess the permeability of blood tumor barrier after IL-1β. Results The tumor barrier model was successfully established by transwell in vitro. When IL-1β treated the model of blood tumor barrier,the expression of VEGF increased,and reached the peak at 60min,and recovered to the initial state at 120min. The permeability of the blood tumor barrier model was the highest at 60min. In addition,our re-sults also found that,the protein expression of plasma membrane microcapsule structure protein caveolin-1 and number of plasma membrane vesicles in brain mi-crocapsule endothelial cells reached peak at 60 min, subsequently reduced and returned to non drug state at 120min. Conclusion IL-1β increases blood tumor barrier permeability,which may be related to IL-1β in-creasing the number of plasma membrane vesicles through VEGF/ caveolin-1 pathway.

Objective:To investigate the effect of human interferon-α-2b(IFN-α-2b) in the treatment of endometriosis by detecting the levels of CA125 and endometrial antibody(EMAb). Methods: Forty-five cases with endometriosis were divided into three groups. Fifteen cases in test group (operation+IFN-α-2b), 20 cases in control group A (operation+Diphereline), 10 cases in control group B(only operation). The blood serum level of CA125 was detected by microparticle enzyme immunochemiluminescent at pre-operation, the first month, second month and third month of the post-operation; and the EMAb level was measured by enzyme linked immunosorbent assay (ELISA). The follow-up of patients was carried out after operation to evaluate the clinical appearances and record the adverse effects of the human IFN-α-2b. Results: Compared with pre-operation, the levels of CA125 and EMAb were obviously degraded in the first to third months after surgery in test group and control group A(P < 0.05). There were no significant difference in the levels of CA125 and EMAb were at pre-operation,the first month,second month and third month of the post-operation between the test group and control group A(P > 0.05). There were no significant difference in the levels of CA125 and EMAb at pre-operation between the test group and control group B(P > 0.05). However, the level of EMAb was lower the first month after operation in the test group than that of control group B. In the follow-up, the adverse effects of the human interferon-α-2b were observed including low-grade fever, articular muscle soreness and gastrointestinal tract complaints. These appearances completely disappeared after drug withdrawal. It had less impact on the menstruation. Conclusion: The levels of CA125 and EMAb were similar in treatment of endometriosis with human IFN-α-2b and with Diphereline. Both of the treatments are better than the pure surgery. It has less impact on the menstruation and can avoid menostasia.

Objective: To explore the clinical value of adenosine triphosphate (ATP) stress99mTc-methoxyisobutylisonitrile (99mTc-MIBI) gated myocardial perfusion imaging (G-MPI) for evaluating the severity and region of myocardial ischemia and left ventricular function in patients with myocardial bridge. Methods: A total of 58 patients with CAG or CTA confirmed diagnosis of myocardial bridge received ATP stress99mTc-MIBI G-MPI examination in our hospital. The short and vertical long-axis image of left ventricular myocardium were divided into 13 segments and the radionuclide distribution was semi-quantitatively evaluated into 4 classes by 0-3 scores visually (0: normal, 1: mild reduction, 2: moderate reduction, 3: severe reduction). The summed stress score (SSS) of left ventricular myocardium was calculated, the severity and region of myocardial ischemia were judged and compared with the severity of myocardial bridge. The LVEF obtained by ATP stress 99mTc-MIBI G-MPI was compared with LVEF obtained by cardiac color ultrasound (UCG).Results: The detection rate of myocardial ischemia by ATP Stress 99mTc-MIBI G-MPI and by 24h dynamic ECGwere 82.76% vs 56.10%, P <0.05. ATP Stress 99mTc-MIBI G-MPI presented abnormal radionuclide distribution in258 segments (63.55%) of LAD supplied territory, 82 (47.13%) of LCX supplied territory and 74 (42.53%) of RCAsupplied territory; the ischemic segments in LAD supplied territory were more than those in LCX and RCA suppliedterritories, P <0.0125. The resting LVEF obtained by ATP Stress 99mTc-MIBI G-MPI and by UCG were (69.59 ± 4.13)% vs (63.22 ± 4.12) %, P >0.05 and they had positive correlation (r =0.555, P <0.05).Conclusion: ATP stress 99mTc-MIBI G-MPI could accurately and intuitively evaluate the severity and region ofmyocardial ischemia and left ventricular function in patients with myocardial bridge, it has certain guiding value inclinical practice.
