OBJECTIVETo observe metabolomic changes in urine of chronic superficial gastritis (CSG) patients with Pi-qi deficiency syndrome (PQDS) or Pi-Wei dampness-heat syndrome (PWDHS), thereby providing scientific evidence for syndrome typing of them.

METHODSUrine samples were collected from CSG patients with PQDS/PWDHS and healthy volunteers, 10 in each group. Proton nuclear magnetic resonance spectroscopy (1H-NMR) based metabonomic analysis was performed on urine samples. Contents of related biomarkers were analyzed by principal component analysis (PCA), partial least square discriminant analysis (PLS-DA), and urivariate statistical analysis.

RESULTSPLS-DA analysis showed that metabolites among CSG patients with PQDS/PWDHS and healthy volunteers could be mutually distinguished. Seven differentially identified metabolites were screened from urines of CSG patients with PQDS and healthy volunteers included glutamate, methionine, α-oxoglutarate, dimethylglycine, creatinine, taurine, and glucose. Four differentially identified metabolites were screened from urines of CSG patients with PWDHS and healthy volunteers included 2-hydroxybutyric acid, trimethylamine oxide, taurine, and hippuric acid. Eleven differentially identified metabolites were screened from urines of CSG patients with PQDS and PWDHS included fucose, β-hydroxybutyric acid, alanine, glutamate, methionine, succinic acid, citric acid, creatinine, glucose, hippuric acid, and lactic acid.

CONCLUSIONThe metabolic differences of CSG patients PQDS and PWDHS mainly manifested in glycometabolism, lipid metabolism, and amino acids catabolism, and 1H-NMR based metabonomics may be used in classified study of Chinese medical syndrome typing.

Drug allergy and pseudoallergic reactions are main adverse drug reactions. Allergy is mainly induced by the immunogenicity of drug, drug metabolic products or drug additive. Pseudoallergic reactions may result from the irritation or activation of inflammatory material release. Pre-clinical evaluation of drug allergy and pseudoallergic reactions is included in immunotoxicity evaluation. Now there is no in vivo or in vitro method that could predict all kinds of allergy or pseudoallergic reactions due to the different mechanisms. In the past few years, FDA, SFDA OECD, ICH and WHO have published several guidelines on per-clinical immunotoxicity evaluation, however, no agreement has been reached on allergy and pseudoallergic reactions evaluation. This article reviews the requirements of allergy and pseudoallergic reactions in pre-clinical evaluation.

OBJECTIVETo assess the expression of HER-2 and leptin in gastric cancer and evaluate their relationship with VEGF expression and clinicopathological features, and their prognostic value for gastric cancer patients.

METHODSOne hundred and ten gastric cancer specimens and the corresponding metastatic lymph nodes were detected for HER-2 by immunohistochemistry (IHC). All primary cancer tissues were detected for leptin, OB-Rb and VEGF. Ninty-six specimens of normal gastric mucosa served as the control.

RESULTSThe expression level of HER-2, leptin and OB-Rb in gastric cancer tissues were significantly higher than those in normal tissues (19.1% vs. 8.0%, 49.1% vs. 34.0%, and 60.9% vs. 46.0%, P < 0.05). HER-2 overexpression was moderately homogenous in primary gastric cancer and matastatic lymph nodes (P = 0.607, Kappa = 0.581). There was a correlation between the expression of HER-2 and leptin, both of which were significantly correlated with tumor invasion depth, metastatic lymph nodes ratio (NR), distal metastasis, TNM stage and VEGF expression. However, there was no significant correlation between OB-Rb expression and the clinicopathological features evaluated. Cox regression multivariate analysis showed that tumor size, histological grade, NR, stage, chemotherapy and HER-2 expression were independent prognostic factors.

CONCLUSIONSHER-2 is stably expressed in primary gastric cancer and metastatic lymph nodes. HER-2 and leptin play an important role in the progression and angiogenesis of gastric cancer. High expression of HER-2 is a prognostic factor for poor outcome.

The prevalence of elderly dementia patients in our country is high, the course is long and the cost is high, the visiting rate is low and it is difficult to cure. The implementation of humanistic care to them is the essen-tial demands of medical spirits, also is a necessary supplement to the poor medical treatment and can also give more psychological support to patients and their families. Therefore, it should establish a sound service system, strength-en health education and cultivate professional accompanying staff, in order to enhance the quality of life of elderly dementia patients and improve the living conditions.

Objective To probe into the mechanism of Feixian Formula ( FXF ) , a Chinese herbal compound, in prevention pulmonary microvascular endothelial cells ( PMVECs) migration and angiogene-sis in vitro. Methods PMVECs isolated from rat model of pulmonary fibrosis ( PF) were cultured and divided into blank group, losartan group, prednisone group, low-, mid-, and high-dose of FXF groups. Migrating cells and new vessels in each group were counted. Results High-dose and mid-dose of FXF and losartan inhibited PMVECs migration significantly ( P <0. 05 ) . High-dose, mid-dose, low-dose of FXF and losartan inhibited formation of new vessels, even high-dose of FXF completely inhibited blood vessel formation. Conclusion The potential mechanism of anti-pulmonary fibrosis of FXF in vitro is related to inhabitation of PMVECs migration and new vessels formation.

OBJECTIVETo investigate the relationship of interleukin-10 gene (IL-10) polymorphism and the serum IL-10 level with restenosis after percutaneous coronary intervention (PCI) in Tianjin Chinese Han population and study the effect of IL-10 gene polymorphism on serum IL-10 level.

METHODSFour hundred and thirty-seven patients who successfully underwent PCI with a follow-up angiography were divided into a restenosis group (n = 166) and non-restenosis group (n = 271). The IL-10 gene promoter polymorphism at position -592 was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Meanwhile their serum IL-10 level before and 24 h after PCI was determined by enzyme-linked immunosorbent assay (ELISA).

RESULTS(1) There was no significant difference in frequencies of -592 genotypes and alleles between the two groups (P > 0.05); (2) The 24 h post-PCI IL-10 serum level of restenosis group was significantly lower than that of the non-restenosis group [(82.67 ± 35.02) ng/L vs. (95.08 ± 32.26) ng/L, P < 0.05]; (3) The serum level of the A allele carriers (AA+AC) was significantly lower than that of the CC carriers [(86.13 ± 34.77) ng/L vs. (102.50 ± 27.52) ng/L, P < 0.05]; (4) In the restenosis group, the 24 h post-PCI serum level of IL-10 in the A allele carriers was also significantly lower than that in those without the A allele [(78.51 ± 34.09) ng/L vs. (102.19 ± 33.66) ng/L, P < 0.05]; (5) Logistic regression analysis revealed positive correlations between acute coronary syndrome patients, pre-PCI degree of stenosis, length of target stenosis lesion and restenosis (OR = 5.90, 1.86, 2.83 respectively); and there were negative correlations between 24 h post-PCI serum level of IL-10, the stent diameter, the diameter of reference vessel before stent implantation and restenosis(OR = 0.99, 0.70, 0.46 respectively).

CONCLUSION(1) The IL-10 gene -592 C/A polymorphism was not associated with restenosis in the Tianjin Chinese Han population; (2) IL-10 is an early post-PCI inflammatory cytokine, 24 h post-PCI serum IL-10 level was an independent predictive factor for restenosis, the IL-10 A allele carriers may have increased incidence of in-stent restenosis (ISR) by reducing the serum IL-10 levels.

Using interval mapping and marker simple regression methods, the QTLs of yield and its components in (Simian 3 x TM-1) F2 and F2:3, were tagged and Mapped with 39 SSR and 10 RAPD markers having polymorphism between parents screened from 301 pair SSR primers and 1040 RAPD primers. Simian 3 is being grown extensively in Yangtze River cotton-growing valley characterized as high productivity with more bolls and higher lint percent, whereas TM-1, Genetic standard in Upland cotton with more heavy boll weight. In the present report, two QTLs controlling boll size with 18.2% and 21.0% phenotype variance explained in F2:3 generation, one QTL controlling lint percent with 24.9% phenotype variance explained in F2 generation and 5.9% in F2:3 generation and one QTL controlling 100-seed weight with 15.6% phenotype variance explained in F2:3 generation were mapped in Chromosome 9. Additionally, another QTL responsible for 100-seed weight was identified and mapped at the same position in Chromosome 9 in F2:3 generation. It is worth for further to be studied whether it is one QTL for pleiotrophism or two closely linked QTLs. The molecular markers mapped and tagged closely with main QTLs of yield traits in this paper can be used for MAS in cotton high-yield breeding program.
