| 1 | The Dynamics of a Predator-prey Model with Ivlev's Functional Response Concerning Integrated Pest Management显示文摘A mathematical model of a predator-prey model with Ivlev's functional response concerning integrated pest management (IPM) is proposed and analyzed. We show that there exists a stable pest-eradication periodic solution when the impulsive period is less than some critical values, Further more, the conditions for the permanence of the system are giverl. By using bifurcation theory, we show the existence and stability of a positive periodic solution. These results are quite different from those of the corresponding system without impulses. Numerical simulation shows that the system we consider has more complex dynamical behaviors.Finally, it is proved that IPM stragey is more effective than the classical one. | BingLiu YingZhi Lan-sunChen | 2004 | Acta Mathematicae Applicatae Sinica2004，20，1： | 8 |

| 3 | Influence of IL-1β and TNF-α on Fas Expression of Human Retinal Pigment Epithelial Cells in Vitro显示文摘Purpose:To observe Fas expression change of cultured human retinal pigment epithelial (RPE) cells by IL-1β and TNF-α.Methods:With flow cytometry, immunohischemistry, and color imaging system, Fas expressions by exposure to IL-1β and/or TNF-α were measured.Results:The gray degree values of Fas expression were 67.5±6.1 in IL-1β+TNF-α-treated group, 80.1±9.2 in IL-1β-treated group, and 70.4±6.4 in TNF-α-treated group, respectively. There were significant differences (P < 0.005) compared with control group (107.0±10.2). Flow cytometry showed that 15.0% cultured human RPE cells expressed Fas. Fas-positive in IL-1β, TNF-α, and IL-1β+TNF-α-treated groups expressed was 28.1%, 34.5%, and 65.2%, respectively. Conclusion:IL-1β, TNF-α, and combining both of them can up-regulate Fas protein expression, which may contribute to more Fas (+) cells in proliferative vitreoretinopathy (PVR). Minimizing this process by means of inducing apoptosis of Fas (+) proliferative cells of Fas/FasL pathway is a future preventive and therapeutic possibility for PVR.

| 5 | Dexamethasone Modulation on Cultured Human Retinal Pigment Epithelial Cell显示文摘Purpose: Dexamethasone(DEX) was tested for its ability to modulate human retinal pigment epithelium (hRPE) cell proliferation in cell culture.
Methods: DEX in different concentrations was added to cultured hRPE cells. The effects were measured with MTT method, 3H-thymidine(3H-TdR) incorporation and flow cytometw.
Results: DEX increased survival rate and DNA synthesis from 32 mg/L to 320 mg/L under hRPE culture conditions, but paradoxically reduced them at 1 000 mg/L and 3 200 mg/L in dose and time dependent fashion by both MTT assay and 3 H-TdR incorporation. The cell numbers in S phase and G2/M phase increased 28.32 % at DEX concentration 320 mg/L, in contrast, reduced 41.84 % at 1 000 mg/L.
Conclusion: DEX increased proliferation from 32 mg/L to 320 mg/L, and inhibited proliferation at concentrations greater than 320 mg/L. The inhibiting effect of DEX may happen in s phase and G2/M phase. Eye Sciernce 2001; 17:27 ~ 30. | BingLiu YannianHui YushengWang HongWei | 2001 | Eye Science2001，17，1： | 3 |

| 10 | Human placenta-derived mesenchymal progenitor cells support culture expansion of long-term culture-initiating cells from cord blood CD34^+ cells显示文摘Objective. Allogeneic transplantation with umbilical cord blood (UCB) in adult recipients is limited mainly by a low CD34^+ cell dose. To overcome this shortcoming, human placenta as a novel source of human mesenchymal progenitor cell (MPC) was incorporated in an attempt to expand CD34^+ ceils from UCB in vitro.Materials and Methods. Human placenta MPC was isolated and characterized by morphologic,immunophenotypical, and functional analysis. UCB CD34^+ cells were expanded by coculturewith placeutal MPC. Suitable aliquots of cells were used to monitor cell production, elonogenie activity, and tong-term culture-initiating culture (LTC-IC) output. Finally, the immunoregulatory effect of placental MPC was evaluated by T-cell proliferation assay.Results. In its undifferentiated state, placental MPC displayed fibroblastoid morphology; was CD73, CD105, CD29, CD44, HLA-ABC, and CD166 positive; produced fibronectin, laminin,and vimentin; but was negative for CD14, CD31, CD34, CD45, HLA-DR, and α-smooth muscle actin. Functionally, it could be induced into adipocytes, osteocytes, and chondrocytes.In vitro expansion of UCB hematopoietic cells, when cocultured with placental MPC in the presence of eytokines, was significantly enhanced: CD34^+ cells by 14.89±2.32 fold; colonyforming cell (CFC) by 36.73±5.79 told; and LTC-IC by 7.43±2.66 fold. Moreover, placental MPC could suppress T-cell proliferation induced by cellular stimuli.Conclusion. These results strongly suggest that human placental MPC may be a suitable feeder layer for expansion of hematopoietic progenitors from UCB in vitro. | YiZhanga ChangdongLi XiaoxiaJiang ShuangxiZhang YingWu BingLiu PeihsienTang NingMao | 2005 | 中国生物学文摘2005，19，3： | 0 |
