OBJECTIVETo investigate the association of SOX9 expression and clinicopathologic factors and prognosis of gastric cancer.

METHODSA retrospective cohort study including 112 gastric cancer patients admitted to the Zhejiang Provincial People's Hospital from 2004 to 2006 was performed. Immunohistochemical analysis was used to evaluate the expression of SOX9 in the 112 specimens of gastric cancer tissues and 70 non-cancerous tissues adjacent to the tumor.

RESULTSLow expression of SOX9 was seen in 5(7.1%) tissues out of 70 non-cancerous tissues adjacent to the tumor. A total of 94(83.9%) patients had varying expression of SOX9, of whom 51(45.4%) had overexpression. Univariate analysis demonstrated that the expression of SOX9 was significantly associated with Lauren classification (P<0.05), tumor invasion(P<0.01), lymph node metastasis(P<0.05), distant metastasis(P<0.05) and tumor stage(P<0.05), however there was no significant association between SOX9 expression and sex, age, histological type, histology differentiation or tumor size. Kaplan-Meier analysis showed that the 5-year survival rate of patients with SOX9 over-expression was significantly lower than that of patients with low expression(29.4% vs. 49.2%, P=0.031). Multivariate Cox regression analysis showed that histology differentiation(P=0.046), tumor invasion(P=0.001), and distant metastasis(P<0.01) were independent prognostic factors for gastric cancer, however the over-expression of SOX9 was not significant(P=0.948).

CONCLUSIONSThe expression SOX9 is associated with the growth, invasion, and metastasis of gastric cancer, as well as the prognosis. However, SOX9 expression is not an independent factor for the prognosis in patients with gastric cancer.

OBJECTIVETo study the effect of red peony root (RPR) on serum proteome in rat suffering from noxious heat with blood stasis Syndrome (NH-BS).

METHODSThe differences of serum proteome among rats in four groups, treated with lipopolysaccharide (LPS), RPR, LPS + RPR and saline respectively, were analyzed by bi-dimensional electrophoresis (2DE) assay. LPS was administered by intravenous injection and RPR by oral intake.

RESULTS(1) Serum of rats with LPS induced NH-BS showed significant changes in volume of serum protein (xPr) in 13 points on 2DE collagen, the volume of xPr 16 and 19 were significantly lower, volume of xPr 1, 2, 3, 4, 6, 7, 8, 9, 11, 12 and 23 were significantly higher respectively, as compared with those in the normal control group. (2) After being treated with RPR, the increased volume of xPr 1, 2, 3, 4 and 9 significantly decreased, and the decreased xPr 16 significantly increased, with xPr 2, 3 restored to normal level but the xPr16 still lower and xPr 1, 4, 9 higher than those in the normal group. RPR showed interaction with LPS on xPr 1, 3, 9, and 16. (3) For xPr 19, the interaction of RPR with LPS might be synergistic. (4) In the group treated with RPR, volumes of xPr 13 and 14 were significantly higher and those of 15, 17 were significantly lower than those in the normal group respectively, but the similar changes didn't found in the LPS group.

CONCLUSIONThe molecular basis of therapeutic effect of RPR on NH-BS might be through the regulation of xPr 1, 2, 3, 4, 9 and 16.

miR-200c has been shown to regulate the epithelial-mesenchymal transition (EMT) by inhibiting ZEB1 and ZEB2 expression in breast cancer cells. This study further examined the role of miR-200c in the invasion and metastasis of breast cancer that goes beyond the regulation on ZEB1 and ZEB2 expression. In this study, the bioinformatics software (miRanda) was used to predict the target gene of miR-200c and Renilla luciferase assay to verify the result. The metastatic breast cancer cells MDA-MB-231 were cultured and transfected with the miR-200c mimic or inhibitor. The expressions of miR-200c and HMGB1 were detected by RT-PCR and Western blotting, respectively. Transwell assay and wound healing assay were employed to examine the invasive and migrating ability of transfected cells. Target prediction and Renilla luciferase analysis revealed that HMGB1 was a putative target gene of miR-200c. After transfection of MDA-MB-231 cells with the miR-200c mimic or inhibitor, the expression of miR-200c was significantly increased or decreased when compared with cells transfected with the miR-200c mimic NC or inhibitor NC. Moreover, the expression of HMGB1 was reversely correlated with that of miR-200c in transfected cells. Tranwell assay showed that the number of invasive cells was significantly reduced in miR-200c mimic group when compared with miR-200c inhibitor group. It was also found that the migrating ability of cells transfected with miR-200c mimics was much lower than that of cells transfected with miR-200c inhibitors. It was suggested that miR-200c can suppress the invasion and migration of breast cancer cells by regulating the expression of HMGB1. miR-200c and HMGB1 may become useful biomarkers for progression of breast cancer and targets of gene therapy.

OBJECTIVETo assess the preventive effects of different dietary regimens on development of eczema and food allergy in infants at high-risk for allergy.

METHODSForty-six infants whose parents were atopic and umbilical cord IgE > 0.35 kU/L were enrolled in the study. The infants were randomly assigned at birth to one of 2 dietary regimen protocols: those in intervention group (23 cases) were breast fed till more than 4 months of age, then followed by feeding with partially hydrolyzed formula (pHF), combined solid foods avoidance until 4-month of age, egg, fish, shrimp avoidance until 12-month of age. The other 23 cases in non-intervention group were breast fed for less than 4 months, or bottle fed with cow's milk-based formula, egg yolk was introduced at 4-month of age, and egg white at 6-month of age, besides, no any other dietary avoidance was applied. All the infants were followed-up for 18 months. The primary end point was the presence of atopic eczema. Food allergy was detected by fresh food prick-to-prick tests or in vitro sIgE or Fx5E.

RESULTSAt 6 months, 12 months and 18 months, the incidence of eczema in intervention group was 4.3% (1/23), 8.7% (2/23), and 17.4% (4/23), respectively, which was significantly reduced as compared to that of the non-intervention group, which was 26.1% (6/23), 34.8% (8/23), and 39.1% (9/23), respectively. Food allergy was found in 13.0% (3/23) of intervention group and 34.8% (9/23) of non-intervention group by skin prick tests or sIgE. Egg white was the most common offending food.

CONCLUSIONEarly life dietary interventions which included breastfeeding, delayed solid food introducing, pHF feeding, and high risk food avoidance could reduce the risk of atopic eczema and food allergy development, and was probably an effective primary intervention method for infants at high risk for atopy.
