Objective To study the significance of expression of hypoxia-inducible factor 1 alpha(HIF-1?) in gastric mucosal diseases. Methods Using tissue chip technique to creat tissue chip in 120 cases of vary gastric mucosal disease,and using S-P immunohistochemical methods to detect the expressions of HIF-1? in these tissue chips. Results The positive rates of HIF-1? was 28.3% in 120 tissue chips of gastric mucosal diseases. The positive rates of HIF-1? was 0, 10.0%, 40.0% and 63.3% in chronic superficial gastritis, chronic atrophic gastritis with intestinal metaplasia, chronic atrophic gastritis with dysplasia and intestinal type gastric cancer, respectively. The positive rates of HIF-1? of intestinal type gastric cancer and chronic atrophic gastritis with dysplasia were significantly higher than that in chronic superficial gastritis and chronic atrophic gastritis with intestinal metaplasia(P

Purpose To investigate the protein expression of p53 and E-cadherin in gastric adenocarcinoma and the effects of them and the clinicopathological parameters on prognosis of patients.Methods Expression of p53,E-cadherin in 150 cases of gastric adenocarcinoma was detected by tissue microarray and immunohistochemistry.The effects of them and the clinicopathological parameters on the prognosis of patients were studied by Kaplan-Meier method to calculate and compare the cumulative survival rate and postoperative mean survival time.Multivariate analysis was also performed by COX regression.Results The positive rate of p53 and E-cadherin expression in 150 cases of gastric adenocarcinoma was 31.3% and 91.3%,respectively.74 cases were followed up, and the 1-,3-,and 5-year survival rates were 83.8%,70.3% and 63.5%,respectively.The invasion, lymph node status and pTNM stages were prognostic factors;multivariate analysis revealed that p53,age and lymph node status were independent prognostic invasion, lymph node status and pTNM stages are important prognostic factors in gastric adenocarcinoma. Nevertheless, E-cadherin and histological classification are not prognostic factors.

Objective To investigate the different expressions of adiponectin receptor 2(AdipoR2) mRNA in liver between diet-induced obese rats and controls.Methods The level of AdipoR2 mRNA expression was detected by reverse transcriptase polymerase chain reaction(RT-PCR).Insulin sensitivity was evaluated by insulin sensitivity index(ISI).Results Diet-induced obese rats showed higher expression of AdipoR2 mRNA compare to controls.The ISI of diet-induced obese rats was lower than that of controls.Conclusion High energy diet induceds AdipoR2 expression in liver.

Objective To investigate the microsurgical treatment of subdural extramedullary tumors in ventral spinal.Methods Retrospectively analyzed 16 cases of subdural extramedullary tumors in ventral spinal which resected by microsurgical technique from January 2000 to December 2013.By summarized the tumor character,location,extent of resection and rehef of symptoms.Results All of 16 cases were successfully resected,in which 14 cases completely resected,2 cases mostly resected.A higher response rate of local symptoms and neurological symptoms obtained postoperatively,2 patients got worse sensory disorders,movement disorder compared with preoperative,cerebrospinal fluid leakage occured in 1 patient.Conclusion Resection of the subdural extramedullary tumors in ventral spinal with microsurgical technique has the advantage of more clearly anatomical level,minimal tissue injury of spinal cord and surrounding tissue,higher tumor removal rate.

Objective To explore the clinical feature of acquired pure amegakdryocytic thrombocytopenic purpura(AATP).Methods 18 patients were analyzed retrospectively.And 112 patients with ITP in the same term were to be control group.Each group's megakaryocytic (MK),platelet (PLT) count,mean platelet volume (MPV) and platelet associated immunoglobulin G(PAIgG) were rested.Results The MK total number of AATP group was obvious decreased or even absent,while the ITP group was increased[(0.8?1.5) vs (195.0?47.3),P0.05).About the PAIgG posi- tive rate,AATP group was 55.6 % while ITP group was 83% (P

In order to study the interaction relationship between secondary metabolites in Glycyrrhiza uralensis, and find out which secondary metabolite is significantly related to the content of glycyrrhizic acid, artificial applying ammonium glycyrrhetate solution was used to establish a high glycyrrhizic acid environment. The change of the 4 secondary metabolites was analyzed within 72 h after glycyrrhizic acid stimulation, while correlation statistical soft was applied to analyze the correlation of glycyrrhizic acid and other compositions. It turned out that it is feasible to establish high glycyrrhizic acid environment by glycyrrhizic acid root soaking in the concentration of 1.0 mmol x L(-1). There was significant positive correlation between glycyrrhizic acid and liquorice glycosides in short-term glycyrrhizic acid stimulation environment. It is concluded that glycyrrhizic acid accumulation internal of G. uralensis could be effected by artificial exogenous glycyrrhizic acid stimulation in certain case, and its accumulation was significantly related to the content of liquorice glycosides.

Objective To construct a model for persistent genital tract infection with Chlamydia trachomatis in mice with low serum iron. Methods Iron deficiency was induced in female BALB/c mice by lowiron diet. Mice with or without iron-deficency were inoculated intravaginally with direct instillation of 50 μl of bacterial suspension containing 3.4344 × 107 IFU/ml of C. trachomatis serovar E elementary body 1 week after intramuscular injection of progesterone. Moxifloxacin and ferrous sulfate, alone or in combination were given to inoculated mice with iron deficiency daily for 1 week. Subsequently, vaginal discharge was obtained from mice and observed under an immunofluorescence microscope, and tissue specimens were resected from the uterus,uterine tube and ovary of mice and subjected to pathological examination at various time points. Results Compared with normal-iron mice, iron-deficient mice were infected with C. trachomatis for a longer duration (more than 18 weeks). After 18-week infection with C. trachomatis, there was an obvious chronic inflammation and lymphocytic infiltration in tissues specimens from the uterus,uterine tube and ovary of mice. Immunofluorescent examination of vaginal discharge for C. trachomatis turned negative in 60% of iron-deficient mice treated with both moxifloxacin and ferrous sulfate, but not in any of those receiving moxifloxacin or ferrous sulfate alone. Conclusion As animal models show, low serum iron may contribute to the persistent genital tract infection with C. trachomatis.
