Objective: To investigate the therapeutic effect of oat β-glucans on serum lipid levels of rats with experimental hyperlipemia. Methods: Rats were fed on high fat forage for 3 weeks to establish hyperlipemia models, then the model rats were orally given oat β-glucans at doses of 133, 266 and 533 mg/(kg · d) separately. At the same time, there were 3 control groups including chitosan ligosaccharide[200 mg/(kg · d)], normal, and high blood lipid (model rats fed with distilled water). Serum levels of total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were assayed in rats of all groups and the results were compared. Results: β-glucans obviously decreased the levels of TC and LDL-C and increased HDL-C in rat hyperlipemia models. The reduction of serum lipid level in 4-week β-glucans treatment rats was more obvious than that in 3-week β-glucans treatment rats. Besides, β-glucans showed an obvious dosage dependent effect in reducing serum lipid level without adverse effect. Oat β-glucans had a better lipid-reducing effect than ligosaccharide did. Conclusion: Oat β-glucans can obviously decrease serum lipid in rats with hyperlipemia.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

Objective To open out new method,we probe into immune function of??ST and NKT cells in NSCLC.Methods The peripheral blood cells were stained with antibodies labeled with fluorescence in NSCLC,??T,NKT and their set group cells were counted with flow cytometry.Results The absolute counts of??T,CD~+_(56)??T,CD~-_(56)??T,NKT and??T~+ NKT cells in NSCLC was significantly lower than that of normal controls.The relative counts of NKT,??T~+ NKT,??T~-NKT and CD~+_56??T cells in NSCLC was not sig- nificantly lower than that of normal control.The absolute counts of??T cells in NSCLC positively correlated to the number of NKT cells,(r=0.426,P=0.009).Conclusion The absolute counts of??T,NKT and their set ground cells in NSCLC was significantly lower than that of normal controls.In NSCLC the relation of the??T and NKT had positive correlation.

A new method was established for the direct, rapid and quantitative analysis of pesticide residues, dimethoate chlorothalonil and malathion by low temperature plasma ( LTP) ionization miniature ion trap mass spectrometer. The LTP ionization probe and sample inlet of ion trap mass spectrometry were enclosed in a metal cavity. With non-contact heating, the samples placed on the sample platform were desorbed into gaseous phase and ionized by LTP ionization probe. The results showed that closed ionization had an edge over the opened ionization. The quantitative analysis of 3 pesticides within the range of 0. 5-10 mg/L was realized by optimizing heating time and flow rate of air, and the relative standard deviations of signal intensity is less than 11%. LODs of pesticide, which were obtained within 5 s, were as low as several hundred pictograms. The results showed that the method could be used for the analysis of pesticide residue on green and organic fruits or vegetables.

Objective To explore the mechanism of opioid-psychic dependence involving the aspects of pre-receptor and receptor by observing the changeable expressions of glutamate neurotransmitter and NR2B of N-methyl-D-aspartic acid (NMDA) receptor in the neuroanatomical circuit of ventral temental area, nucleus accumbens and prefrontal cortex (VTA-Nac-PFC) of rats subjected to morphine-induced conditioned place preference (CPP). Methods The models of CPP were validated by escalating doses of morphine in rats (n=16). The colorimetry and immunohistochemistry ways were applied to detect the contents of glutamic acid and the expression level of NR2B in VTA, Nac and PFC. Results As compared with those in the control group physiological saline), the prolonged detention time of white compartment in the model group was notably observed (P<0.05), and increased content of glutamic acid and expression level of NR2B in fields of VTA, Nac and PFC in the model group were significantly detected (P<0.05). Conclusion Increased level of giutamic acid and expression level of NR2B in nuroanatomieal circuit of VTA, Nac and PFC could play key roles in inducing morphine-psychic dependent rats.

OBJECTIVETo investigate the correlation between coronary atherosclerotic heart disease (CAD) and periodontal disease (PD).

METHODForty-five patients with CAD (CAD group) and 40 patients without CAD (control group) were compared with their pathological changes of periodontal tissues and inflammatory markers [high sensitive C reactive protein (hsCRP), interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha (TNF-alpha)].

RESULTSUnivariate analysis showed that the prevalence of PD was 84.44% in CAD group and 22.50% in control group (P < 0.01). The levels of hsCRP, IL-1beta, and TNF-alpha were (5.75 +/- 1.26) mg/L, (10.32 +/- 2.96) ng/L, and (9.17 +/- 2.14) ng/L in CAD group and (1.13 +/- 0.73) mg/ L, (2.87 +/- 1.45) ng/L, and (5.84 +/- 1.96) ng/L in control group (P < 0.01). Gingival index and plaque index were statistically different between two both groups (P < 0.01). Logistic regression analysis showed that in addition to pulse pressure and low density lipoprotein cholesterol, periodontal disease index was a higher risk factor of CAD. Its relative risk was 1.217 (95% CI was 1.120-1.805, P < 0.05).

CONCLUSIONPD can cause CAD. The improvement of public oral health plays an important role in the prevention and treatment of CAD.

Bio-active components from Carthamus tinctorius were separated on the basis of antioxidant capacities in vitro. The antioxidant capacity was investigated on the basis of the ability to scavenge DPPH radical, ABTS radical and reduce Fe3+ of different polar fractions. Furthermore, the chemical compounds were isolated from bio-active fraction, and were evaluated for the antioxidative effects. Five major components were isolated and identified from water extract as 6-hydroxykaempferol 3,6,7-tri-O-β-D-glucoside(1), 6-hydroxykaempferol 3-O-β-rutinoside-6-O-β-D-glucoside (2), 6-hydroxykaempferol 3-O-β-D-glucoside (3), hydroxysafflor yellow A (4) and anhydrosafflor yellow B (5). By evaluating and comparing the antioxidative effects of different fractions and obtained compounds, the results showed that water extract displayed significantly high antioxidative activities and 6-hydroxykaempferol glycosides and quinochalcone C-glycosides were found as main contribution for antioxidant property.
