Objective To investigate the protective effects of insulin like growth factor 1(IGF-1) on cortical neurons under condition of hypoxia and the possible mechanism. Methods Cerebral cortical neurons from newborn rats were cultured under the condition of oxygen and glucose deprivation (OGD) . On day 7, neurons were treated with IGF-1 or IGF-1 plus LY294002 or PD98059 under condition of OGD or normal condition. MTT assay was used to analyze the viability of neurons in each group. The expression of total Akt and p-Akt were analyzed by Western blot. Results Compared with the control, the neuron viability was significantly higher in IGF-1 treated group under normal or OGD condition (P＜0.05). The protective effects of IGF-1 were attenuated in the presence of LY294002 but not PD98059. The result of Western blot showed IGF-1 upregulated the expression of p-Akt, which was inhibited by LY294002. Conclusion PI3K pathway may play an important role in neuroprotection afforded by IGF-1.

BACKGROUND: By detecting vasoactive substances of experimental rats with myocardial ischemia, pharmacological mechanism of xiongbitong was studied in this research.OBJECTIVE: To observe the effect of xiongbitong capsule on release of vasoactive substances of rats with myocardial ischemia.DESIGN: A completely randomized controlled study.SETTING: Department of Health, Weifang Medical College; Department of Physiology, Department of Immunity and Pathogenic Biology, Department of Internal Medicine, Weifang College of Traditional Chinese Medicine.MATERIALS: The experiment had been carried out in the Laboratory of Physiology of Weifang Medical College from January 2003 to June 2003.The cleansing grade 30 Wistar rats, 6-8 months, of either sex, were randomly divided into three groups:namely, normal control group, model control group and model group of treatment with xiongbitong capsule.METHODS: [1] At 12 hours before making model, rats of model treatment group were irrigated with xiongbitong capsule 2.5 g/kg (a capsule contents dried medicinal herbs 1 g), which consists of tuckahoe, rhizoma, immature bitter orange, exocarpium citri grandis, rhizoma acori tatarinowi, moxibustion, dalbergia wood, mongolian snakegourd, curcuma root, red sage root,root of donopsis pilosula, ilyturf root, ophiopogon, polygala root, date kernel etc., and dissolved in 4 mL physiological saline. AT ten hours after making model, they were irrigated with same dose once more. The rats of normal control group and model control group were irrigated with the same dose physiological saline at the same time. One hour after the first irrigation, the animal models of myocardial ischemia of rats of model control group and model treatment group were established by injecting vitriol isoprenaline according to 10 mg/kg subcutaneously. [2] Endothelin (ET), calcitonin generelates peptide (CGRP), 6-keto-prostaglandin Fl alpha (6-keto-PGF1α) and thromboxane B2 (TXB2) in the plasma of rats were detected according to the explanation of Institute of Beijing East Asia Immune Technique. [3] The analysis of variance and q test were used for comparing between groups.MAIN OUTCOME MEASURES: Contents of vasoactive substances in the plasma of rats in each experimental group.RESULTS: The date of all thirty rats was entered the final analysis. [1]The contents of (TXB2) and ET, TXB2/6-Keto-PGF1α, ET/CGRP: Compared with the model group, the normal control group and model treatment group reduced obviously (q=2.99-9.87, P ＜ 0.05-0.01). [2] The contents of 6-Ke-to-PGF1α and CGRP: Compared with the model group, the normal control group and model treatment group increased obviously [(603.3 ±90.6),(190.0±64.2) ng/L; (560.7±111.1), (174.9±41.4) ng/L; (380.4±705),(114.9±36.4) ng/L, q=3.88-7.64, P ＜ 0.05-0.01].CONCLUSION: Xiongbitong capsule may suppress unusual release of vasoactive material at myocardial ischemia area obviously, increase the content of expanding the blood vessel material, and correct out-of-balance of content of important TXB2, 6-keto-PGF1α, XTB and CGRP in the body.

Microglia cells are immune cells in the central nervous system.When the microenvironment of brain has changed,microglia will respond rapidly.ATP,UTP,or other nucleotide signals released by neurons from damaged site and their metabolites such as ADP,adenosine,UDP and so on will bind with the purinergic receptors on microglia to regulate the morphology and function of microglia,then the microglial cells activated by nucleotide signals are to regulate neural cells by phagocytosis or releasing cytokines.In this article,the function and corresponding mechanisms of nucleotide signals on chemotaxis,phagocytosis,and process retraction are reviewed.

AIM: To investigate the effect of high glucose toxicity on JNK pathway and cell function of INS-1 cells.METHODS: Cultured INS-1 cells with or without IGF-1 exposure, were treated with glucose at 3 concentrations (5.6 mmol/L, 11.2 mmol/L and 33.3mmol/L), respectively. MTT was used to measure the cell viability. Apoptosis was determined by immuno-fluorescence and flow-cytometry analysis. The serine 270 phosphorylation of IRS and phosphorylation of JNK in INS-1 cells were detected in the presence or absence of SP600125 treatment.RESULTS: The cell viability decreased and apoptosis increased with elevated glucose concentrations. The percentage of apoptosis cells was 11.3% in 5.6 G group, 12.7% in 11.2 G group and 28.2% in 33.3 G group. There was remarkable increase in apoptosis in 33.3 G group with a 2.49-fold increase to the cells in the basal 5.6 mmol/L glucose. High glucose activated the serine 270 phosphorylation of IRS correlates with JNK phosphorylation in INS-1 cells. Using Western blotting analysis, the levels of JNK phosphorylation were 3.33 fold increased and serine 270 phosphorylation of IRS was 1.17 fold increased in 33.3 G group compared to 11.2 G group (P<0.01). IGF-1 treatment inhibited phosphorylation of JNK and IRS. SP600125 treatment completely blocked JNK phosphorylation in 11.2 G group and reduced JNK phosphorylation by 90% in 33.3 G group. In addition, SP600125 treatment partly reduced serine 270 phosphorylation of IRS by 88.3% in 11.2 G group and 80% in 33.3 G group, the viability of INS-1 cells increased and the apoptosis decreased.CONCLUSION: The toxicity of chronic high glucose, which inhibits the cells viability and induces the cell apoptosis, might be related to suppress IRS signal by activating the JNK pathway. Blocking the JNK pathway might relieve the effect of glucose toxicity to the β cell function by improving the IRS signal pathway.
