Academic Journal of Second Military Medical University 2006;27(8):863-866
Objective: To establish a white noise-induced stress ulcer model in rats and to assess the changes of gastric parietal cell configuration and acid secretion under noise stress. Methods: Rats were randomly divided into 3 groups: NS 4 h,8 h and control groups. The rat NS model was induced by white noise. The pH values of gastric juice were measured by the pH/mV pH meter and the gastric ulcer index (UI) was evaluated. The stomach tissue was processed for immunofluorescence detection and the β subunit of H+, K+-ATPase was immunostained. The gastric parietal cell configuration was observed with conventional microscopy and confocal laser scanning microscope. Results: (1)The pH value of NS 4 h group (2.22±0.05) was significantly lower than that of control group (2.59±0.21, P<0.05), but higher than that of NS 8 h group (1.31±0.06, P<0.01). (2) The UI of NS 4 h group (10.5±1.29) was significantly higher than that of the control group (P<0.05), but significantly lower than that of NS 8 h group (34.36 ± 2.22, P < 0.01). (3) The reticular pattern parietal cells in NS 4 h group (55.5±3.42)/100 was significantly higher than that in control group (42.5±3.70/100, P<0.01), but lower than that in NS 8 h groups (62.0±3.46/100, P<0.05). (4) The pH was negatively related with both UI (r=-0.85, P<0.05) and the number of reticular parietal cells (r=-0.89, P<0.05). Conclusion: A white noise-induced stress ulcer model has been successfully established in rats. NS rats develop gastric mucosal lesions with increased acid secretion, which is closely related with the oxyntic function of parietal cells.

Objective To explore the dignostic value of the candidate molecular markers in Urothelium carcinoma based on Illumina Transcriptome Sequencing. Methods Candidate genes which were screened with transcriptome sequencing were validated by using real-time fluorescent quantitative PCR in 31 pairs of tumor and normal tissues of Urothelium carcinoma patients from Affliated Hai kou Hospital Xiangya School of Medicine Central South University. Results The four candidate genes (CDH1,VEGFA,PTPRF and CLDN7) in tumor tissues were up-regulated compared with normal groups in samples of sequencing. The relative expression of VEGFA mRNA were higher than that in normal tissues. There were significant difference in two groups (P<0.05). PTPRF and CLDN7 were also up-regulated, but no significant difference was found (P > 0.05). PTPRF was closely related with the recurrence of tumor (P=0.002), and the predict sensitivity and speciality rate were 90.0%and 83.3%respectively. Conclusions CDH1 and VEGFA play important roles in the occurrence and development of bladder urothelial carcinoma, and they may be the possible biomarkers. PTPRF is expected to be a molecular reference recurrent predictor of bladder tumor.

Objective To have knowledge of the exact cause of massive osteolysis. Methods Hair of patients from Xinjiang province was collected and 14 trace elements were determined by inductively coupled plasma mass spectrometryICP-MS. Results Trace elements imbalance in the body of patients was disturbed. Chromium and zinc which are benefit to the growth of the bones were only 0.5 ?g/g and 40 ?g/g respectively that were much lower compared with the healthy persons cadmium was much higher than the limit level in healthy person. Moreover the quantity and ratio of potassium and sodium in the patients were obvious abnormal. Conclusion According to the result of the present paper may be the environmental and dietary factors play an important role in pathogenesis of this disease.

Objective To study the correlation between normal level of thyroid hormone and gensini coronary scor-ing system. Methods Coronary heart disease patient who were treated with Cardio-angiography (CAG) (n=231) were divid-ed into 4 groups based on gensini coronary score. All the patients were examined with indexes include total triiodothyronine (TT3), total thyronine(TT4), free thyronine(FT4), free triiodothyronine (FT3), thyroid stimulating hormone (TSH). And correla-tion between thyroid hormone level and gensini coronary scoring system was studied by Spearman correlation analysis and Multiple regression analysis. Results No significant difference was found in the levels of TT3, TT4, FT4, Cholesterol(CHO) and Triglyceride(TG) between the all 4 groups (P>0.05). FT3 and HDL-C decreased with the increase of extent of coronary artery lesions(P<0.01), and AGE and LDL-C raised with the coronary artery lesions extent (P<0.05). Gensini coronary scoring system was linearly negatively correlated with FT3, HDL-C and positively correlated with age and LDL-C. Age, FT3,HDL-C,LDL-C was independently correlated to Gensini score. Conclusion The lower level of FT3 is an indepen-dent risk factor for CHD.
