OBJECTIVE To investigate the relationship between the single nucleotide polymorphisms (SNP) of tumor necrosis factor-alpha (TNF-alpha) promoter genes and susceptibility to gastric adenocarcinoma or gastric adenocarcinoma with helicobacter pylori (Hp) infection. METHODS The SNPs of the TNF-alpha (-238G/A and -308G/A) were determined by gene chip in 130(More)
OBJECTIVE In order to clarify the trend of change in lactase and its gene regulation pattern, the authors determined the lactase activities and mRNA levels in BALB/c mice at different ages. METHODS The lactase activities and mRNA levels of the 3-, 5-, 7-, 9- week old mice were determined by the modified method of Dahlqvist and in situ hybridization(More)
OBJECTIVE To observe the expression of protein arginine N-methyltransferase (PRMT) genes in the lung and spleen of E3 rats with acute asthma. METHODS E3 rats with ovalbumin-induced pulmonary inflammation were divided into two groups (n=10), and the validity of the acute asthma model was evaluated by histological observation with HE and PAS staining and by(More)
UT-B is a urea transporter protein expressed in the kidney and in many non-renal tissues including erythrocytes, brain, heart, bladder and the testis. The objective of this study was to determine the phenotype of UT-B deletion in the heart. UT-B expression in the heart was studied in wild-type mice vs UT-B null mice by utilizing RT-PCR and Western blot. A(More)
OBJECTIVE To study the epidemiologic features of functional bowel disorders (FBD) among medical students and science and engineering students in Zhejiang province, China, and to explore the relationship between psychological factors and FBD. METHODS This study was a survey of random sampling based on the Rome III Diagnostic Questionnaire (Rome III-DQ)(More)
GNAO1 (guanine nucleotide-binding protein, α-activating activity polypeptide O) is a member of the subunit family of Gα proteins, which are molecular switchers controlling signal transductions and whose deregulation can promote oncogenesis. HCC (hepatocellular carcinoma) is one of the malignant tumours around the world, which summons novel biomarkers or(More)
OBJECTIVE To compare the effectiveness and safety of radiofrequency ablation (RFA) with other therapeutic methods for patients with early hepatocellular carcinoma (HCC). METHODS Randomized clinical trials (RCTs) which compared the efficacy or safety of RFA with other therapeutic methods for primary hepatocellular carcinoma in Cochrane library, EMBASE,(More)
OBJECTIVE To explore the role of altered characteristics of intestinal dendritic cell (DC) in the induction of visceral hyperalgesia through the activation of mast cells in a rat model of irritable bowel syndrome (IBS). METHODS A total of 20 Sprague-Dawley rats were divided into modeling and control groups (n = 10 each). The IBS rat model was established(More)
The feasibility of wood identification of softwood and hardwood by near infrared spectroscopy (NIR) coupled with partial least squares discriminant analysis (PLS-DA) was investigated in the present paper. The near infrared spectra (780 - 2 500 nm) were collected from wood cross-section from one softwood species (Chinese fir) and one hardwood species(More)
Rosewood is a kind of precious wood which include many wood species. It's difficult to most people to identify rosewood species. Near infrared spectroscopy (NIR) of eight rosewood species was investigated in the present paper. The results showed that (1) there was significant correlation between near infrared spectroscopy and color parameters expressed by(More)
