Objective This study aimed at the effect of glutamate(Glu) on rat cortical pyramidal cells in cultured brain slices treated by threohydroxyaspartate(THA),an inhibitor of glutamate transporter.Methods The brain slice cultures were prepared using 1-day-old rat.Various concentrations of THA(50,100 and(500 ?mol/L))were added into the culture medium respectively.Cortical pyramidal cells' survival was evaluated by immunohistochemistry staining monoclonal antibody SMI-32,a nonphosphorylated neurofilament marker,Glu level in the culture medium was also measured.Ultrastructural picture of neuropathology were examined by EM microscopy. Results The brain slices in the control group maintain excellent organization and a stable population of pyramidal cells.THA caused a slow dose-dependent loss of cortical pyramidal cells and an increase of Glu level in the culture medium.THA of 100 ?mol/L resulted in a significant decrease in cortical pyramidal cells after culturing for 5 weeks.Pyramidal cells appeared vacuolar degeneration.Conclu-(sions Extra-cellular) Glu caused chronic excitotoxicity to cortical pyramidal cells.

Objective: To study the inhibitory effect of VEGF antisense oligonucleotides (ASODN) on growth of Lewis lung cancer in C57BL/6 mice.Methods: Lewis lung cancer cells were cultured and implanted subcutaneously into 40 C57BL/6 mice, which were then divided into 4 groups: VEGF-ASODN treatment group, VEGF-SODN treatment group, BEGF-MODN treatment,and control group (normal saline). Mice in different groups were treated 24 hours after cell inoculation. The weight and volume of subcutaneous tumors was measured and the morphological changes of tumor cells was observed under microscope. VEGF protein and microvessel density were examined by immunohistochemistry.Partial tumor tissues were kept in liguid nitrogon.Results: The average tumor weights of the control, VEGF-ASODN, VEGF-SODN and VEGF-MODN groups were (7.33?0.71)g, (4.56?0.38) g, (7.59?0.32) g, and (7.62?0.39) g, respectively. The inhibition rates of tumor growth in VEGF-ASODN, VEGF-SODN and VEGF-MODN group were 43.8%, 5.5% and 3.1%, respectively. VEGF-ASPODN obviously inhibited the tumor cell growth and decelerated the tumor cell proliferation. Immunohistochemistry results showed that the expression of VEGF in ASODN group was remarkly lower than those in SODN group, MODN group and control group (P

Objectives: China has observed an increasing prevalence of cardiovascular diseases among its population, which is putting heavy economic burden both on individuals and the whole society.Conducting a multi-angle study of cardiovascular patients with economic burden can help adjust the health care policy to reduce the economic burden of patients.Methods: Using the baseline data (2011) and follow-up data (2013) of the China Health and Retirement Longitudinal Survey, this study selected cardiovascular patients aged 45 and above to calculate their direct medical cost, direct non-medical cost as well as self-paid cost before and after reimbursement.The total cost and self-paid cost are both calculated, and gender difference and rural-urban difference are also analyzed.Results: The prevalence of cardiovascular disease among the population age 45 and above was 13.9% in 2013 and 12.1% in 2011, while the prevalence in women was higher than in men and urban areas higher than rural areas.The average annual total costs for individual patient before reimbursement in 2013 was lower than that in 2011, but contrary to the trend of self-pay costs.Urban patients had higher amount of direct medical cost, lower co-payment rate and lower non-medical cost such as transportation and accommodation than their rural counterpart.Both urban and rural patients self-paid more on outpatient services than inpatient services.Conclusion: Based on these analyses, this paper suggests that Chinese policy makers should look deeper into patient behaviors as well as their economic burden before revising the current health policy.More practices regarding to the unbalanced distribution of health resources between urban and rural areas are needed, in order to ensure patients living in remote areas could get access to appropriate treatment without paying heavy non-medical cost.
