Gastric tuberculosis is a rare disease. It usually occurs secondarily to another lesions and mainly in the lungs. Only a few cases of primary gastric tuberculosis have been reported in the literature. Most commonly, gastric tuberculosis lesion locates in the lesser curvature side of the antrum. Therefore the clinical picture is similar to the peptic ulcer. A 24-year-old women visited to the Inha university hospital complaining of vomiting and epigastric discomfort. Gastrofiberscopy showed multiple polypoid mass around the pylorus with stenotic pyloric channel. Subtotal gastrectomy was performed and histologic examination revealed chronic granulomatous inflammation with caseation necrosis. That is compatible with tuberculosis. The patient was taken antituberculosis medication without complication. So we report the case of pyloric obstruction due to gastric tuberculosis with review of the literature.

OBJECTIVETo study the prevalence and clinical characteristics of the A to G mutation at nucleotide 3243 of the mitochondrial tRNA(Leu(UUR)) gene in familial diabetes in Shanghai, Jiangsu and Zhejiang Province of China.

METHODSThe mt3243 A to G mutation in 770 randomly selected, unrelated probands of diabetic pedigrees were screened by PCR-RFLP technique and PCR-direct sequencing. Genetic and clinical analyses were further performed in the probands and their family members.

RESULTSThirteen diabetic patients (13/770, 1.69%) with mt3243 A to G mutation were detected. Eleven diabetic patients and 8 normal glucose tolerance (NGT) first-degree relatives of these 13 probands were also found bearing the mutation. Seventeen patients were associated with sensory hearing loss. In the 24 patients harboring the mutation, the majority had lower body mass index (BMI), 18 showed typical maternal inheritance, 15 had sensory hearing loss, 13 had insulin resistance and 14 required insulin therapy due to secondary failure to oral hypoglycemic agents.

CONCLUSIONThe mutation of mt3243 A to G in the mitochondrial tRNA(Leu(UUR)) gene is an important cause of diabetes in Shanghai, Jiangsu and Zhejiang Province of China. Mitochondrial gene mutation diabetes (MDM) is clinically characterized by early onset, emaciation, maternal inheritance, sensorineural hearing loss, and lower islet beta cell function, and some have insulin resistance.

OBJECTIVETo study the significance of vascular endothelial growth factor (VEGF) and microvascular density (MVD) expression in breast cancer.

METHODSThe expression of MVD and VEGF was studied in 81 patients with primary breast cancer by SP immunohistochemical technique.

RESULTSThere were 49 patients with high VEGF expression (60.5%) and 35 patients with high MVD expression (43.2%). There was significant correlation between VEGF or MVD expression and TNM stage, but not age, tumor size, ER expression or lymph node status. VEGF was significantly related with MVD expression. Univariate analysis showed that patients with low expression of VEGF and MVD had longer disease free survival (DFS) and overall survival (OS). Grouping univariate analysis showed that VEGF had significant correlation with the DFS of all grouped patients and the OS of patients with LN(+) or stage III lesions. MVD had significant correlation with the DFS and OS of LN(+) patients and the DFS of stage III lesion patients. Multivariate analysis showed that MVD was a risk predictor because of its positive statistic value, the higher expression, the shorter survival time of the patients.

CONCLUSIONBoth VEGF and MVD are useful prognostic factors in breast cancer. MVD appears to be a strong and independent biologic marker for breast cancer prognosis.

OBJECTIVETo study the effects of exogenous ER beta on the growth of breast cancer MCF-7 cells under different treatment.

METHODSAn eukaryotic expression vector containing 1.6 kb of human entire coding sequence of ER beta (pCDNA3-ER beta) was transfected into human breast cancer MCF-7 cells using lipofectamine 2000. The biological activity of ER beta was detected with the luciferase reporter containing estrogen responsive element (ERE) and the expression of ER beta protein by Western blot. The growth properties of MCF-7, pCDNA 3-transfected MCF-7 and pCDNA 3-ER beta-transfected MCF-7 cells under different treatment, including E2 (17beta-estradiol) and 4-OHT (4-hydroxytamoxifen), were observed.

RESULTSA stronger activation of the reporter by ER beta in the presence of E2 was observed in the pCDNA 3-ER beta-transfected MCF-7 cells than in the pCDNA 3-transfected MCF-7 and in MCF-7 cells. Western blot analysis showed that the protein level of ER beta in the pCDNA 3-ER beta-transfected MCF-7 cells was markedly increased. Exogenous ER beta expression did not change the growth properties and the morphology of MCF-7 cells under normal condition. The pCDNA 3-ER beta-transfected MCF-7 cells proliferated at the same rate as naive cells in the presence of 4-OHT, whereas a strong inhibition of the proliferation of the pCDNA 3-ER beta-transfected MCF-7 cells in the presence of E2 was observed.

CONCLUSIONExogenous ER beta expression does not increase the resistance to 4-OHT, and a strong inhibition of the proliferation may occur in the presence of E2.
