Objective To Investigate the effects of antipsoriatic drugs on 5 lipoxygenase(5－LO) and set up a relevant pharmacodynamic method. Methods 5－ LO products, leukotriene B4 (LTB4) and 5 hydroxyeicosatetraenoic(5－HETE), we re determined by RP－HPLC to represent 5－LO activity. Results Cyclosporin A( CyA) and triptolide(T0) inhibited the production of LTB4 and 5－HETE in a dose dependent manner, while erythromycin did without dose dependence. The 50％ inhibitory concentration values(IC50) of CyA inhibiting LTB4 and 5－HETE were 3 8.0? g/mL and 0.96? g/mL, respectively. The IC50 of T0 inhibiting LTB4 and 5－ HETE were 2.3? 10－6? g/mL and 1.14? 10－6? g/mL, respectively. Conclusio ns The anti inflammatory effect of Tripterygium wilfordii Hook.f. may be partl y explained by its inhibition of 5－LO activity. The anti inflammatory effect of CyA has no clinical significance since the inhibitory concentration of CyA h as exceeded its pharmacological limitation. Erythromycin has no effect on 5－LO activity.

Objective To analyse distribution of age and gender characteristics of specific IgG(sIgG)antibodies and specific IgE (sIgE)antibodies of 13 types of food allergens in patients with food anaphylaxis,and to explore the relationship between sIgG and sIgE in food anaphylaxis.Methods 314 cases of patients from 2009 to 2012 were selected as subjects,and divided into underage group(1 63 cases)and adult group(1 5 1 cases).Serum sIgG of 13 types of food allergens were detected by using enzyme linked immu-nosorbent assay,serum sIgE of these food allergens were detected by using immune capture.Results 80.25% of the patients were sIgG-positive,and no obvious gender differences were found;while the positive rates of sIgG in the underage group(94.48%)were higher than that in the adult group(64.90%),there were statistically significant differences(P < 0.05 ).34.39% of the patients were sIgE-positive.The positive rates of sIgE in male patients(40.68%)were higher than that in female patients(26.28%),and that in the underage group(55.21%)were also higher than that in the adults group(1 1.92%),there were statistically significant differences(P <0.05).Conclusion The total positive rates and its distribution characteristics of sIgG and sIgE of same food aller-gens were obviously different.Food anaphylaxis might be associated with age,gender,food types and individual diversity.

This study was aimed to observe different forms of β-amyloid peptide (Aβ) and insulin degrading enzyme (IDE) in the hippocampus and cortex in order to further explore the role of Aβ and IDE on spleen yin deficiency di-abetes-associated cognitive decline (DACD), and the effect of Zi-Bu Pi-Y in method. The rats were randomly divided into five groups, which were the blank control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and Zi-Bu Pi-Y in recipe (ZBPYR) group. Soluble and insoluble Aβ in the hippocampus and cortex of rats were extracted by gradient centrifugation, and then measured by ELISA. The ex-pression of IDE was observed by western blot. The results showed that the content of soluble and insoluble Aβ1-42 in the hippocampus and cortex of the DM group and piDM group were higher than the Cont group. The soluble and in-soluble Aβ1-42 content in the hippocampus and cortex of the ZBPYR group were reduced compared with the DM group and the piDM group. The soluble Aβ1-40 in the cortex of the DM group, pi group and piDM group were in-creased compared with the Cont group (P < 0.05). The soluble Aβ1-40 content of the ZBPYR group was decreased compared with the DM group and the piDM group (P < 0.05). The expression of IDE protein was decreased in the hippocampus of the DM group and the piDM group compared with the Cont group (P< 0.05), and the IDE protein level in the hippocampus of the ZBPYR group was increased compared with the DM group and the piDM group (P<0.05). The expression of IDE protein in the cortex of the DM group, pi group and piDM group was lower than the Cont group (P< 0.05). The IDE protein level in the cortex of the ZBPYR group was reduced compared to the DM group (P< 0.05). It was concluded that the increased Aβ1-42 in brain may be a major pathological change of DACD and spleen yin deficiency DACD. The decreased IDE expression may be one of the reasons to induce increasing of Aβ1-42 level. The Zi-Bu Pi-Y in method may decrease the Aβ1-42 content by upregulating IDE protein expression.

Aim Our previous study has found that ur-solic acid( UA) increased intracellular reactive oxygen species ( ROS ) production and adenosine monophos-phate-activated protein kinase ( AMPK ) phosphoryla-tion, inhibited signal transducer and activator of tran-scription 3 ( STAT3 ) phosphorylation and cyclooxygen-ase-2 ( COX-2 ) expression in gastric cancer cells . However , the molecular mechanism by which UA in-hibits COX-2 expression in gastric cancer cells has not been fully clarified .In this study we aimed to further clarify the signal transduction pathways involved in the UA-mediated inhibition of COX-2 expression in gastric cancer cells .Methods Human gastric cancer cell lines SGC-7901 and MKN-45 were routinely cultured in RPMI-1640 medium supplemented with 10% heat-in-activated fetal calf serum .Sub-confluent cell cultures were pre-treated with antioxidant N-acetylcysteine ( NAC) , AMPK activator 5-amino-4-imida-zolecarbox-amide-riboside ( AICAR ) , AMPK inhibitor compound C, or STAT3 inhibitor WP1066 and then treated with or without UA for 24 h.The expression of AMPK and phosphorylated AMPK ( p-AMPK ) , STAT3 and phos-phorylated STAT3 ( p-STAT3 ) , as well as COX-2 was detected by Western blot analysis .Results Antioxi-dant NAC and AMPK inhibitor compound C blocked UA-induced inhibition of STAT 3 phosphorylation and down-regulation of COX-2 expression in gastric cancer cells.Both AMPK activator AICAR and UA inhibited STAT3 phosphorylation and COX-2 expression; the combination of two drugs resulted in further reduction . STAT3 inhibitor WP1066 did not affect UA-induced AMPK phosphorylation , whereas it inhibited STAT3 phosphorylation and COX-2 expression .The inhibitory effects on the STAT3 phosphorylation and COX-2 ex-pression were significantly enhanced when SGC-7901 and MKN-45 cells were treated simultaneously with WP1066 plus UA.Conclusion UA inhibits COX-2 expression in gastric cancer cells , which may be medi-ated through ROS/AMPK/STAT3 signal transduction pathway .

Cai which are stem or heartwood of trees or stem of woody liana are a kind of medicinal plant resources traditionally used by Li Minoriy. Ethnobotanical methods were adopted for the investigation on traditional utilization of cai. Totally, 44 species in 26 families and 30 genera were reported to be used as cai. Most of the species were applied as decoction (70.5%) and medicinal liquor (27.3%) to treat a wide range of diseases, such as rheuma-toid arthritis (34.1%), liver diseases (18.2%), injuries and weak (15.9% respectively). Through literature survey, it was found that 7 species (15.9%) were used by Li Minority only. Besides, 13 species (29.5%) were used differently compared with that of Traditional Chinese Medicine. Consequently, it is indicated that indigenous knowledge of using medicinal plants by Li Minority is unique.
