Objective To investigate the effect of lipoteichoic acid of bifidobacterium (BLTA) on the expressions of Fas/FasL in bearing melanoma B16 cancer mice. Methods Forty C57BL/6 mice were randomly divided into 4 groups (n=10),normal saline group (NS group),low-dose BLTA group (50 mg/L),middle-dose BLTA group (100 mg/L),and high-dose BLTA group (150 mg/L). Melanoma B16 cells (0.2 ml 5?109/L) were subcutaneously injected into the mice of the later 3 groups,and then,0.2 ml BLTA at corresponding doses was injected subcutaneously at the sites around the mass once a day for 10 d when the tumor (at least 2 mm?2 mm) was palpable. The NS group was given normal saline at same volume as in BLTA group. The changes of the killing activity of CTL was examined by MTT assay. The expression of the tumor-infiltrating CD4+ and CD8+ lymphocytes in tumor tissue were detected by immunohistochemistry. RT-PCR was used to detect the mRNA expression variance of the Fas and FasL in tumor and spleen tissue. The protein expression of Fas,FasL in tumor tissue and lymphocytes of spleen were detected by immunohistochemistry and Western blotting. Results Compared with the control group,BLTA significantly improved the CTL killing activity (P0.05). Conclusion BLTA enhances the killing activity of CTL by regulating Fas/FasL system,and thus,promotes apoptosis of tumor cells to suppress tumor immune escape in tumor-bearing mice,thereby it exerts anti-tumor effect further.

Tumor microvessel including two modes,as one is classic vascular structures surrounded with vascular endothelial cells and the other is vasculogenic mimicry( VM) surrounded with cancer cells.Recent studies suggested that anti-angiogenic drugs can inhibit classic microvessel structure significantly, but can not inhibit VM formation and even promote VM formation further more.This is one of the reasons affecting its clinical effica-cy.However,basic research has shown that traditional chinese medicine,gene therapy and drugs which is targeting for VM formation have an unique advantage in anti-VM.In this review, we summarize the progress of cancer therapy on targeting vasculogenic mimicry,and provide a basic for the development of new drugs for cancer thera-py through targeting both angiogenesis and VM formation.

BACKGROUND: Research has proved that nifedipine can improve the functions of vascular endothelial cells. However, it still needs further study on its mechanism on dilating vessels.OBJECTIVE: To observe the effects of controlled-release nifedipine to nitrogen monoxide(NO) and induced nitric oxide synthase(iNOS) in spontaneously hypertensive rats(SHR).DESIGN: Comparative observational study based on experimental animals.SETTING: Experimental animal centre in a medical college.MATERIALS: This study was completed in Experimental Animal Centre of Shandong University during April to May 2002. Twenty-one recombinant inbred rats of clean class with body mass of(300 ± 2) grams were provided by Experimental Animal Centre of Shandong University. They were randomly divided into three groups: control group, normal group and low dose group,each with 7 rats.METHODS: Saline(10 mL/kg), 10 mL/kg and 3 mL/kg controlled-release nifedipine solution(0. 3 g/L) were poured into stomach to rats in control group, normal dose group and low dose group once everyday for 15 days respectively. Eyeball was removed to collect blood and heart and lung were removed at the same time to test the content of NO and iNOS in serum after last administration.MAIN OUTCOME MEASURES: Content of NO, comparison of iNOS activity between groups.RESULTS: There was significant difference on NO content between normal dose group and control group, low dose group after 15 days' administration ( P < 0. 01 ) . Compared with control group and low dose group, there was significant difference on the iNOS activity in heart and lung of normal dose group(P <0.01, P <0.05).CONCLUSION: While nifedipine reduces the blood pressure, it can also improve the content of NO and resist the increasing activity of iNOS casued by increased blood pressure.

[ ABSTRACT] Diabetes is characterized by an absolute or relative deficiency inβ-cell mass, which cannot be re-versed with existing therapeutic strategies.The restoration of the endogenous islet β-cells can stabilize the level of blood glucose.The isletβ-cells can be obtained from the directional differentiation of stem cells, but the process is complex and has the risk of teratomas generation.Cell direct reprogramming, one terminal differentiated cell can transdifferentiate into another kind of terminal differentiated cell, which is other than directional differentiation from stem cells.Direct reprogram-ming gives rise to the generation of isletβ-cells from one terminal differentiated cell, may be preferable for diabetes therapy because of its unique advantage.

Objective To study the effect of environmental estrogen, bisphenol A (BPA), on proliferation of human uterine leiomyoma cells in culture. Methods The primary culture and subculture of the human uterine leiomyoma cells which were identified at each passage by means immunocytochemical staining with a monoclonal anti-?-smooth muscle actin antibody, were performed. The cells (passage 3-5) were incubated with BPA (including three dosimetric systems, 1?10-7 mol/L, 50 ?10-7 mol/L and 100?10-7 mol/L) for 24, 48 and 72 h, and the control cells received only the vehicle (ethanol, 0.1 %, V/V). The proliferation of cultured human uterine leiomyoma cells was analyzed by MTT assay and flow cytometry. Results The limited human uterine leiomyoma cell lines were successfully established. After 24 h, 48 h and 72 h of treatment in 100?10-7 mol/L and 48 h, 72 h, at 50?10-7 mol/L , BPA could enhance the cells proliferation. After 72 h of treatment in 50?10-7 mol/L and 100?10-7 mol/L, BPA promoted cells into S cell cycle phase and elevated mitotic index (P
