Objective To investigate the potential role of angiotensinⅡ(AngⅡ)-angiotensinⅡreceptor 1 (ATRI) pathway on inflammatory activation in the lung of rats. Method Twenty four Sprague-Dawley rats were randomly divided into four groups: control group, Ang II group, AngⅡ+losartan group and losartan group. Lung wet/dry weight (W/D) was recorded to assess lung injury. The total lung homogenates were prepared to detect nuclear factor-kappa B (NF-?B) activation by electrophoretic mobility gel shift assary (EMSA), tumor necrosis factor (TNF)-?mRNA expression by reverse transcription polymerase chain reaction (RT-PCR), myeloperoxidase (MPO) and malondialdehyde (MDA) by colorimetry. Plasma yon Willebrand Factor (vWF) were assessed by enzyme-linked immunosorbent assay (ELISA). Meanwhile, pathological changes were examined under optical microscope. Results Histologically, alveolar edema, hemorrhage, and massive inflammatory cell infiltration were observed in AngⅡgroup, but not in control group and losartan group. Compared with AngⅡgroup, histological injury was lesser in AngⅡ+ losartan group. In AngⅡgroup, lung W/D, NF-?B activation, TNF-?mRNA expression, MPO, MDA and vWF were markedly higher than those in the other three groups. There were not significant differences of lung W/D, NF-?B activation, TNF-?mRNA expression, MPO, MDA and vWF in control group, AngⅡ+ losartan group and losartan group. Conclusions Systemic infusion of AngⅡcould up- regulate inflammatory mediator expression and induce lung injury in rats. AngⅡ, acting mainly through ATRI, induced inflammatory activation in the lung of rats.

Objective To explore the role of CD 30 on CD4 + T lymphocyte and T lymphocyte subset activation in asthma pathogenesis.Methods Twenty seven asthma active attack patients,16 acute upper respiratory infection patients and 19 control children were randomly selected. Direct immunofluorescence flow cytometry was used to detect the CD 30 positive percentage on CD4 +cell; ELISA was used to detect the levels of interleukin(IL) 4 and IL 13 in culture supernatants of peripheral blood mononuclear cells(PBMC) and plasma total immunoglobulin E(IgE) level.Results Compared with control group and acute upper respiratory infection group, in asthmatic children the CD4 +CD 30 + percentage on CD4 + cell was elevated significantly; 2.The levels of IL 4 and IL 13 in supernatants of cultured lymphocyte were increased significantly, the plasma total IgE level was increased significantly;3.There was a significant positive correlation of CD4 +CD 30 + cell percentage with the levels of IL 4 and IL 13 in culture supernatants and plasma total IgE.Conclusions The cell that could produce Th2 derived cytokine may consist of CD 30 +cell;When CD 30 L combined with CD 30 on CD4 + cells ,it might result in Th2 cell proliferation ,develop and release Th2 derived cytokine; IL 4 and IL 13 could induce B cell production and secrete more IgE. It is suggested that CD 30 and imbalance of Th2 subset may play an important role in asthma pathogenesis.

During the process of growth, harvesting, transportation, processing and storage, Chinese herbal medicines (CHMs) can be easily contaminated by fungi and their metabolites like mycotoxins, which not only express negative effects on the quality and safety of CHMs and their processed products, but also pose great threats to human health. Now, some chemical synthetic fungicides have been frequently used to control the growth of fungi and accumulation of mycotoxins in the preservation of CHMs. However, the concentration and type of chemical fungicides allowed for postharvest application are restricted due to the disadvantages of their high residual toxicity, long degradation period and pollution to the environment and so on. Therefore, it is critical to research and develop some highly effective, safe and non-toxic, natural, environment-friendly fungistatic agents from plants to prevent CHMs from being contaminated by fungi and mycotoxins. The paper reviews mycotoxins and their harmfulness, the effective compounds of fungistatic plants as well as the antifungal mechanism to provide scientific evidences for developing novel and effective fungistatic agents plants. Then, the application prospect of fungistatic agents from plants in the preservation of CHMs was discussed.

Objective To investigate the expression of caspase-10 in differentiated thyroid carcinoma and association with its development and metastasis. Methods Thyroid samples from 37 patients in a period from January 2006 to December 2007, with differentiated thyroid carcinoma were retrospectively analyzed for caspase-10 by immunohistocbemistry(streptavidin-perosidase, S-P), compared to control group of 46 cases with nodtdar goiter. The relationship between the expression of caspase-10 and the clinical pathologic characteristics of thyroid carcinoma were also explored simultaneously. Results caspase-10 were observed as brown or yellow particles located in the cytoplasm or cell membrane of nodular goiter but there were no significant evidence for its positive expression in thyroid carcinoma, caspase-10 expression was markedly down-regulated in differentiated thyroid carcinoma(29.73%,11/37) compared with benign nodules(71.74%,33/46, χ2=14.528, P<0.01). The positive expression in 18 cases with lymph node metastasis(11.11%,2/18) was significantly lower than those in 19 patients without lymph node metastasis(47.37%,9/19; χ2=4.210, P<0.01). There was no significant correlation(P> 0.05) between the expression of caspase-10 and the clinical pathologic characteristics including male, age, TNM stage and pathologic type. Conclusion Down-regulation of caspase-10 may play a critical role in carcinogenesis and development of differentiated thyroid carcinoma.

This research established an HPLC method for determination of six C-Glycoside flavones of warer-soluble total flavonoids from Isodon lophanthoides var. gerardianus (Benth.) H. Hara, and studied the antitumor activity of the warer-soluble total flavonoids. The HPLC system consisted of Kromasil 100-5 C18 (4.6 mm x 250 mm, 5 microm) column and a solution system of methanol, acetonitrile and 0.5% formic acid gradient elution at a flow rate of 0. 8 mL x min(-1) and the wavelength of detector was at 334 nm. The column temperature was 25 degrees C. The antitumor activity of water-soluble flavonoids was assayed using HepG2 cell as the tested cell. The linear ranges of vicenin II, vicenin III, isoschaftoside, schaftoside, vitexin, 6, 8-di-C-a-L-arabinosylapigenin were 0.25-2.53, 0.12-1.20, 0.37-3.69, 0.16-1.63, 0.19-1.92, 0.14-1.42 microg, respectively. The average recoveries (n = 6) were 99.6% (RSD 0.87%), 100.2% (RSD 2.0%), 99.6% (RSD 1.8%), 97.9% (RSD 1.5%), 98.8% (RSD 1.2%), 98.6% (RSD 1.2%), respectively. After exposure in 24, 48, 72 h, the total flavonoids showed inhibitory effect on the proliferation of HepG2 cells with IC50 as the evaluation index, the IC50 values of 1.89, 1.71, 1.51 g x L(-1), respectively. The method is quick, simple and accurate with good re- producibility, and can be used for determination of vicenin II, vicenin III, isoschaftoside, schaftoside, vitexin, 6, 8-di-C-a-L-arabino- sylapigenin in the warer-soluble total flavonoids from L lophanthoides var. gerardianus. The warer-soluble total flavonoids from L lophanthoides have inhibitory effect on the proliferation of HepG2 cells.

Ongoing study on the chemical constituents of the roots of Macleaya microcarpa led to the isolation of eight compounds of derivatives of triterpenes and organic acids in addition to some previously identified benzophenanthridines. The eight compounds were identified by spectroscopic methods as well as comparison with literature values as 1-oxo-2, 22 (30)-hopandien-29-oic acid (1), 3-oxo-12-oleanen-30-oic acid (2), 3α-hydroxy-12-oleanen-30-oic acid (3), 3β-hydroxy-12-oleanen-30-oic acid (4), ferulic acid (5), ferulic acid 4-O-β-D-glucoside (6), 3-O-feruloylquinic acid (7), and methyl 3-O-feruloylquinate (8). Of which, 1 is a new triterpenoid of hopanes and 2-8 are isolated from M microcarpa for the first time. In order to discover natural active compounds as potential agents of anti-ulcerative colitis (UC), an in vitro drug high-throughput screening model targeted x-box-binding protein 1 (xbp1) was employed to evaluate the activity of the major chemical constituents of M microcarpa. The result confirmed that two dihydrobenzophenanthridines, dihydrosanguinarine (9) and dihydrochelerythrine (10), showed a certain activity on activating the transcription of xbpl, a transcription factor (TF) associated with the occurrence, development, and potential treatment of UC, with their relative activating ratios being 1.76 and 1.77 times, respectively, as compared with control group.

PURPOSE: Genetic variation in fibroblast growth factor receptor 2 (FGFR2) is a newly described risk factor for breast cancer. This study aimed to evaluate the association of four single nucleotide polymorphisms (SNPs) in FGFR2 with breast cancer in Han Chinese women. METHODS: Two hundred three women with breast cancer and 200 breast cancer-free age-matched controls were selected. Four SNPs (rs2981579, rs1219648, rs2420946, and rs2981582) and their haplotypes were analyzed to test for their association with breast cancer susceptibility. The presence of the four FGFR2 SNPs was determined by polymerase chain reaction-restriction fragment length polymorphism analysis. RESULTS: A statistically significant difference was observed in the frequency of rs2981582 in the FGFR2 gene (p<0.05) between case and control groups. In subjects stratified by menopausal status, rs2981582 TT, rs2420946 AA, and rs1219648 CC were significantly associated with the risk of breast cancer in postmenopausal subjects, but no significant associations between these four SNPs and the risk of breast cancer were identified in premenopausal subjects. Further, there was no significant association between hormone receptor status (estrogen receptor and progesterone receptor) and breast cancer risk. Six common (> 3%) haplotypes were identified. Three of these haplotypes, CGTC (odds ratio [OR], 0.613; 95% confidence interval [CI], 0.457-0.82; p=0.001), TGTC (OR, 6.561; 95% CI, 2.064-20.854; p<0.001), and CATC (OR, 12.645; 95% CI, 1.742-91.799; p=0.001) were significantly associated with breast cancer risk. CONCLUSION: Our findings indicated that the SNP rs2981582 and haplotypes CGTC, TGTC, and CATC in FGFR2 may be associated with an increased risk of breast cancer in Han Chinese women.
