1.Advance in differential proteomics of high expression of gastrin-based colorectal neoplasms research
Journal of International Oncology 2011;38(3):216-220
The abnormal expression of gastrins and their receptors have close relationship with the occurrenceand the development of some colorectal neoplasms.The high expression of gastrins and their receptors promote colorectal neoplasms cell proliferation and inhibit apoptosis.The biological behavior is mainly rely on the abnormal expression of protein.Using differential proteomics can screen differential expression protein of high expression of gastrin-based colorectal neoplasms in the occurrence and development process,and then with the regulation of specific proteins to achieve the prevention and treatment of colorectal neoplasms purposes.
2.The prophylactic effects of statins on cardiovascular events in patients with normal level of plasma lipids
Chinese Pharmacological Bulletin 2003;0(11):-
Primary and secondary prevention clinical trials have demonstrated that statins markedly reduced cardiovascular risks even in patients whose plasma level of low-density lipoprotein cholesterol is lower than that of drug-treatment goal in lipid management guidelines. The reasons are as follows: The "normal" level in guidelines is not the normal level biologically, it is merely an average value in a given human group; The composition of plasma lipids is very complex; Statins have effects other than lipid modifying. Statins should be prescribed in patients without hyperlipidemia but with risk factors or coronary heart disease.

This research is to investigate study the flavonoids from stems of Nelumbo nucifera and the cytotoxic activities of iso- lated compounds. The constituents were separated by column chromatography,and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for cytoxic activities by MTT method. Twelve compounds were isolated and identified as rhamnazin-3-O-beta-D-glucopyranoside (1), luteolin-3', 4'-dimethylether-7-O-beta-D-glucoside (2), kaempferol-3-O-beta-D-xylopyranosyl-(1-->2)-O-beta-D-glucopyranoside (3), quercetin-3,3'-di-O-beta-D-glucopyranoside (4), 1, 8-dihydroxy-3,7-dimethoxyxanthone (5), isorhamnetin-3-O-beta-D-glucopyranoside(6) , kaempferol(7), isorhamnetin (8), quercetin(9), astragalin(10), hyperoside (11) and 1-hy- droxy-3,7,8-trimethoxyxanthone(12). All compounds were isolated from stems of this plant for the first time, and compounds 1-5 were firstly isolated from the family nelumbonaceae. Compounds 24 and 6 showed significant cytotoxic activities against BEL-7402 carcinoma cell lines at a concentration of 1 x 10(-5) mol x L(-1) with the inhibitory rate of 67.36%, 53.25%, 57.78%, 60.13% and 52.11%, respectively.

The risk of stroke increases significantly after transient ischemic attack (TIA). TIA is an independent risk factor for cerebral infarction. This article review s the advances in prediction models of stroke risk after TIA in order to conduct rapid and accurate risk assessment and stratification in patients w ith TIA and develop timely reasonable treatment strategies, thereby reducing the risk of stroke.

Objective To investigate the effect of FTY720 and gemcitabine on the proliferation and apoptosis of H520 and A549 cells in non-small cell lung cancer(NSCLC) cell line.Methods The interventional influence on the in vitro cultured NSCLC A549 and H520 cells was performed by selecting 0,2,4,6,8,10 μmol/L concentrations of FTY720,then the absorbance value was detected at 24,48,72 h after culture and the proliferation inhibiting effects of FTY720 on A549 and H520 were observed under the condition of different concentration of FTY720;adding single 7 μmol/L of FTY720,single 0.2 μmol/L gemcitabine and 37 μmol / L FTY720 combined with 0.2 mol/L gemcitabine into A549 and H520 cells lines,then the differences of inhibition and apoptosis after 48 h in the cells of each group were observed.Results The inhibitory effect of different concentrations of FTY270 on NSCLC A549 and H520 cell lines was statistically significant difference (P<0.05).The proliferation inhibiting effect of FTY720 on NSCLC H520 and A549 cell lines had the correlation with the concentration and time.The apoptosis rate of FTY720 combined with gemcitabine on A549 and H520 cells was significantly higher than that of single use in these two drugs (P<0.05).Conclusion FTY720 combined with gemcitabine can significantly inhibit the proliferation of A549 and H520 in human NSCLC,and can effectively promote the apoptosis of cancer cells,and has the higher clinical value.

Objective: Stress, coping and mental health of the different educational level groups, the different gender groups and the different ages groups were studied. Methods: Ss (N=4 745) of a group corporation evaluated their stress levels, ways of coping and mental health with a self-developed Social Stressor Questionnaire, Simplified Coping Style Questionnaire and SCL-90 scale. Results: The lower educated groups scored lowest in social stressor, positive coping (PC), negative coping (NC) and SCL-90.The higher educated groups scored highest in social stressor, PC and NC, Man scored higher in social stressor, PC and NC, but lower in SCL-90 than women. The younger groups scored higher in social stressor and SCL-90 than older group. Conclusion: The result showed the latter education can improve mental health.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and lecukoencephalopathy (CADASIL) is a recently described neurovascular disease affecting young to middle aged individuals. The disease is caused by mutations in the Notch3 gene located in the long arm of chromosome 19. The disease clinically is characterized by migrainous headaches ,mood disturbances, focal neurologic deficits, transient ischemic attaches, strokes and dementia. Pathologically, the disease is characterized by a stereotypic degeneration of the arterial walls with deposition in the media of a nonatheromatous,(nonamyloidotic) substance that under the electron microscope (EM) appears as a granular osmiophilic material (GOM). A review of current literature is presented concerning the clinical, radiological, pathologic and genetic feature of CADASIL.
