3.Inoculation of murine bone marrow mesenchymal stem cells induces tumor necrosis in mouse with orthotopic hepatocellular carcinoma
Journal of Peking University(Health Sciences) 2003;0(05):-
Objective:To observe whether murine bone marrow mesenchymal stem cells(MSCs)implantation improves the survival of hepatocellular carcinoma(HCC)-bearing mice,and to investigate whether MSCs can differentiate to hepatocytes in HCC microenvironment in a mouse model of orthotopic HCC and its effects on tumor cells.Methods:Murine bone morrow MSCs were obtained through adherent culture method combined with magnetic cell sorting CD45-,CD11b-cells,labeled with CFSE in vitro.Phenotypes of MSCs were analyzed by flow cytometry.A murine model of orthotopic HCC was induced by intrahepatic injection of 5?105 murine H22 hepatoma cells in a BALB/c mouse.In this experiment,twelve BALB/c mice were randomly divided into MSCs implantation and saline administration groups on the 7th day after establishment of orthotropic HCC.CFSE labeled MSCs were injected into tumor and/or normal liver tissue in MSCs implantation group.The life span of HCC-bearing mice was observed.After three weeks,albumin was determined by immunohistochemistry.The livers of HCC-bearing mice were observed by light microscopy.Results:In MSCs group,the mean survival time was 25 days(95%Confidence interval:22-28 d),while,in the control group,mean survival time was 21 days(95%CI:20-23 d).However,the statistical difference was not obvious between the two groups(P=0.0713).It showed that the CFSE labeled cells mainly localized in the border of tumor,also a few in the tumor bed,and expressed albumin.Interestingly,there was a larger area of necrosis in the tumor bed,compared with that in the controls.Conclusion:It can be concluded that MSCs not only could engraft in livers of carcinoma-bearing BALB/c mice,but also could differentiate to hepatocyte-like cell.At the same time,MSCs might induce tumor cells necrosis.Further mechanism need to be studied.
5.Clinical application of a simple mini-size perfusion cannula for continuous douche accompanied with negative pressure drainage
Journal of Medical Postgraduates 2003;0(12):-
Objective:The purpose is to observe the clinical results of the continuous douche and negative pressure drainage technic in treating the large hypodermal infected lacuna. Methods: The simple mini-size perfusion cannula for continuous douche and negative pressure drainage was handmade and used on 23 patients suffering from large hypodermal infected lacuna. Results: All of the 23 patients achieved primary healing from large hypodermal infected lacuna. Conclusion:The use of self-made mini-size perfusion cannula for continuous douche accompanied with negative pressure drainage is a good method to treat large hypodermal infected lacuna. It is very economic、efficient and easy.
6.Relationship between expression of sex hormone receptor and tumor central artery in meningiomas
Journal of Clinical Neurology 1993;0(03):-
Objective To investigate the expression of sex hormone receptor (SHR) in meningioma and its relationships to the origin of tumor central artery.Methods The expressions of sex hormone receptors, including progesterone receptor (PR), androgen receptor (AR) and estrogen receptor (ER) in 43 cases with meningioma were detected by immunohistochemically streptavidin-peroxidase (SP) method. These data combined with the characteristics of digital subtraction angiography (DSA) were analyzed.Results The expression of ER in meningioma was not related to the origin of tumor central artery. The positive expression rates of PR and AR in external carotid artery (ECA) original group (26.9%,23.1%) were significantly lower than those in internal carotid artery (ICA) original group (88.9%,77.8%) and ECA combined with ICA group (87.5%,87.5%) (all P
7.Clinical Follow-up Results in 33 Patients With Pacemaker Implantation With Home Monitoring System
Chinese Circulation Journal 2015;(12):1178-1181
Objective: To study the clinical value of home monitoring system of pacemaker and implantable cardioverter-deifbrillators (ICD) in relevant patients.
Methods: A total of 33 patients with home monitoring system of pacemaker implantation or ICD treated in our hospital from 2011-02 to 2014-07 were retrospectively recruited. There were 28 patients with dual chamber pacemaker, 4 with ICD and 1 with cardiac resynchronization therapy pacemaker (CRTP). The patients included 23 male and 10 female at the age of (68.4 ± 9.2) years. The rate of successful data transmission, threshold changes and arrhythmia occurrence were analyzed.
Results: Up to 2014-10, a total 24516 messages were successfully transmitted with the success rate of 97.4%, the rate of no-message transmission was 2.6%. The home monitoring system fund 89 abnormal events including 73 disease related events (82.0%) and 16 system related events (18.0%).
Conclusion: Home monitoring system was a safe, reliable and effective monitoring equipment for cardiovascular implantable electronic devices; according to transmitted message, the parameters of devices could be adjusted in time for treating arrhythmia in relevant patients.
8.Effect of gp120mAb on long-term potentiation inhibited by HIV-1 gp120 in rat hippocampus in vitro
Chinese Journal of Immunology 1985;0(05):-
Objective:To explor the effect of gp120mAb on synaptic transmission and plasticity changed by gp120 in the CA 1 region of rat hippocampal slices.Methods:We recorded the excitatory postsynaptic potentials (EPSP) and investigated effect of gp120mAb on long-term potentiation inhibited by gp120 in rat hippocampus in vitro.Results:The results showed that HIV-1 gp120 can inhibit the LTP induced by high-frequence stimulation schaffer in CA 1,gp120 had no effect on basal synaptic transmission.HIV-1 gp120(200 pmol/L) can inhibit the LTP maintance,gp120mAb of gp120-specific antibodies can reverse the inhibition effect,But IgG can't reverse it.Conclusion:The reverse effect of gp120-specific antibody gp120mAb on long-term potentiation inhibited by HIV-1 gp120 may contribute to the HAD pathogenesis.
