G46B is a promising holding line used for three-lines breeding strategy in hybrid rice, but it is susceptible to blast disease caused by Pyricularia grisea. To improve its blast resistance, three rice varieties, Digu, BL-1, and Pi-4, with blast resistance genes, Pi-d(t), Pi-b, and Pi-ta2, respectively, were used to be crossed with G46B, and 15 plants with(More)
OBJECTIVE To detect the serum protein profiles of Kazakh's esophageal carcinoma (EC) patients in Xinjiang by SELDI-TOF-MS (surface enhanced laser desorption & ionization time-of-flight mass spectrometry) and build up a diagnostic model of Kazakh's EC in Xinjiang. METHODS The serum samples from 41 Kazakh's EC patients and 20 Kazakh's healthy controls were(More)
Fifty-four Sprague-Dawley rats weighing 200~240 g were randomly divided into sham-operated group (sham group), vehicle-treated SNL group (model group), and Tan IIA-treated SNL group (Tan IIA group). Tan IIA was administered intraperitoneally to rats in the Tan IIA-treated group at a dose of 30 mg/kg daily for 14 days after SNL surgery. Paw withdrawal(More)
OBJECTIVE To study the correlation between amplification of chromosome 1 and histological typing and clinical staging of thymic epithelial tumors according to the WHO classification. METHODS Amplification of chromosome 1 was detected by interphase fluorescence in-situ hybridization (FISH) in 60 cases of thymic epithelial tumors, including type A thymoma(More)
OBJECTIVE To study the clinicopathologic characteristics of thymic epithelial tumors and to evaluate the diagnostic reproducibility and clinical relevance of the 2004 WHO histologic classification system. METHODS The morphology and immunophenotype of 52 cases of thymic epithelial tumor were reviewed. The tumors were classified according to the new WHO(More)
OBJECTIVE To study the correlation between loss of heterozygosity (LOH) on chromosome 10q and pathologic features, pathogenesis, prognosis of astrocytic tumors. METHODS LOH on 10q was studied by interphase fluorescence in-situ hybridization (FISH) in 85 cases of astrocytic tumor, including 35 cases of WHO grade II tumors and 50 cases of WHO grade IV(More)
The KRAS gene mutation is involved in several types of tumors. However, the potential role of the KRAS mutation in human primary and paired metastatic colorectal cancer (CRC) among different nationalities is poorly understood. In the present study, we assessed the relationship between KRAS mutation status and overall survival (OS) and disease-free survival(More)
