Objective To investigate the expression of CDX2 and its clinical significance in gastric intestinal epithelial tissue,and investigate the relationship between expression of CDX2 and infection of Helicobacter pylori.Methods The expression of CDX2 was studied by immunohistochemical technique in 93 cases of gastric mucosa (including 7 cases of normal gastric mucosa,21 cases of superficial gastritis,22cases of atrophic gastritis,43 cases of atrophic gastritis with intestinal metaplasia).14C urea breath test was used to detect the Helicobacter pylori infection.Results Helicobacter pylori was negative in 7 cases of normal gastric mucosa,the positive rate of Helicobacter pylori infection in atrophic gastritis and atrophic gastritis with intestinal metaplasia was 77.27％ (17/22),65.12％ (28/43),significantly higher than that of superficial gastritis [ 19.05％(4/21 )] (P ＜0.01 ).No expression of CDX2 was observed in normal gastric mucosa and superficial gastritis.The positive rate of CDX2 in atrophic gastritis with intestinal metaplasia was 83.72％(36/43 ),which was higher than that in atrophic gastritis [40.91％(9/22)](P＜ 0.01 ).Conclusions The infection of Helicobacter pylori and the expression of CDX2 are significantly associated with intestinal metaplasia.The abnormal expression of CDX2 might be the origin of intestinal metaplasia.The detection of gastric mucosa of CDX2 expression can be used to identify the intestinal metaplasia of gastric mucosa,predict the progress of gastric precancerous lesions,and provide a basis for the selection of treatment program.

Objective To find a new therapy for chronic bacillary prostatitis (CBP) with intervention. Methods According to Seldinger way, the catheter was inserted into internal iliac artery or inferior vesical artery percutaneously and was perfused medicine. Results Of which 10 cases recovered and 2 increasingly improved. And there was no positive prostate bacterial culture. But after 3 to 6 month survey, one patient relapse. Conclusion The arterial-cathertered perfusion is a safe, simple and low recurrence way for CBP and available to further study.

Objective To study whether the leakage of polymethylmethacrylate (PMMA) can lead to pulmonary embolism in vertebroplasty (VP), and to observe the correlation of embolism degree with the doses of PMMA. Methods Fifteen canines were randomly divided into 3 groups: group A, B, C, and were injected 0.5, 1.0, 2.0 ml PMMA into the femoral veins, respectively. Before and after the injection, chest CT and angiography of pulmonary artery were performed, the pressure of pulmonary artery was measured, and the blood gas analysis of femoral artery was done. At last, the canines were euthanized and examined and histologically after HE-stained. Results In group C, the pressure of O_2 decreased obviously, and significant difference was found between before and 10 min after injection (P<0.05). The pressure of CO_2 increased quickly in group C, significant difference was detected between before and 1 min after injection (P<0.05). Pressure of pulmonary artery in both group B and C were significantly different between before and after injection (P<0.05). Conclusion The leakage of PMMA can lead to pulmonary embolism. The degree of pulmonary embolism is correlated to the doses of PMMA. The large dose of bone cement leakage can lead to disorder of respiratory function.

Objective To investigate clinical characteristics of patients with ST-elevation myocardial infarction (STEMI) and hypokalemia and the effects of hypokalemia on prognosis. Methods Consecutive 216 cases with STEMI who underwent emergency PCI were divided into group A (serum potassium ＜ 3.5 mmol/L) and group B (serum potassium＞3.5 mmol/L). Infarct site, infarct interrelated artery, peak level of CK-MB and cTnT were compared between two groups. Post-infarctional angina pectoris, arrhythmia, heart failure and cardiac death were compared. Results (1 )The percentage of anterior wall myocardial infarction , left anterior descending artery (LAD) lesions in group A were significantly higher than those in group B [61.2%(41/67) vs. 44.3%(66/149),55.2%(37/67)vs. 38.9%(58/149),P = 0.022,0.026]. The peak levels of CK-MB and cTnT in group A were significantly higher than those in group B [(194.39 ± 101.27) μg/L vs. (115.35 ±78.62)μg/L,(19.16 ±11.48)μg/L vs. (9.07 ±7.65) μg/L,P = 0.004,0.002].(2)Left ventricular ejection fraction in group A was significant lower than that in group B (P - 0.003). The incidence rates of post-infarctional angina pectoris, ventricular tachycardia, ventricular fibrillation and heart failure were significantly higher in group A [43.3%(29/67),32.8%(22/67), 11.9%(8/67),37.3%(25/67)] than those in group B [24.8%(37/149),18.1%(27/149),4.0%(6/149),20.8%(31/149)](P = 0.006, 0.017, 0.029, 0.010). Conclusions Hypokalemia is associated with infarct site and infarct interrelated artery. Hypokalemia has bad effect on prognosis of STEMI.

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on NAFLD in MSG-IR mice and to provide mechanism insights into its therapeutic effect. The MSG-IR mice with insulin resistance were treated with high dose (0.1 micromol.kg-1d-1) and low dose (0.025 micromol.kg-1d-1) of FGF21 once a day for 5 weeks. Body weight was measured weekly. At the end of the experiment, serum lipids, insulin and aminotransferases were measured. Hepatic steatosis was observed. The expression of key genes regulating energy metabolism were detected by real-time PCR. The results showed that after 5 weeks treatment, both doses of FGF21 reduced body weight (P<0.01), corrected dyslipidemia (P<0.01), reversed steatosis and restored the liver morphology in the MSG model mice and significantly ameliorated insulin resistance. Additionally, real-time PCR showed that FGF21 significantly reduced transcription levels of fat synthetic genes, decreased fat synthesis and promoted lipolysis and energy metabolism by up-regulating key genes of lipolysis, thereby liver fat accumulation was reduced and liver function was restored to normal levels. In conclusion, FGF21 significantly reduces body weight of the MSG-IR mice, ameliorates insulin resistance, reverses hepatic steatosis. These findings provide a theoretical support for clinical application of FGF21 as a novel therapeutics for treatment of NAFLD.

Objective To investigate the health seeking intention and its influencing factors among patients with type 2 diabetes in Chongqing Chronic Disease Management System.Methods Multistage cluster random sampling was used to investigate basic information,diabetes-related treatment situation including first heal seeking and reasons for choosing medical institutions in the last year.Relative risk ratios (RRR) and its influencing factors were analyzed with the method of multi-nominal Logistic regression,as community as a reference.Results Over the past year,38.02％ of type 2 diabetes patients preferred to hospitals above the county level,36.78％ preferred to pharmacy or clinics,and 25.21％ preferred to community health service centers.Univariate analysis showed that different education levels,family income levels,health insurance and therapies were significantly different from health seeking intention.Multi-nominal Logistic regression results indicated that higher educational level (RRR =2.39,95％ CI:1.20-4.78),higher income level (RRR =3.37,95％CI:1.44 -7.88),applying to specific diseases medical insurance (RRR =3.32,95 ％CI:1.72-6.42),the use of insulin and oral hypoglycemic agents (RRR =5.02,95％CI:1.15-22.00) of respondents were more inclined to the hospitals above the county level,rather than community health services.Conclusions Health seeking intention of type 2 diabetes patients preferred to hospital above the county level in Chongqing.Type 2 diabetes was an important disease of non-infectious chronic diseases,while the patients preferred go to utilize hospitals rather than community services.

This study aimed at investigating the inhibitory effects and the anti-tumor mechanisms of co-adminis-tration of fusion proteins mGM-CSF/βhCG ( GC ) and hVEGF121/βhCG ( VC ) on RM-1 prostatic cancer and B16 F10 melanoma in the C57 BL/6 J mouse model. Two recombinant stains containing pET-28 a-mGM-CSF-X10-βhCGCTP37 and pET-28 a-VEGF-M2-X10-βhCG-CTP37 were induced by lactose to express fusion proteins. The fusion proteins were separated and purified to prepare the anti-tumor protein vaccines ( VC protein vaccine and GC protein vaccine) , which were then mixed to prepare a combined protein vaccine named VGC protein vac-cine. The prostatic cancer and melanoma tumor-bearing mice C57 BL/6 J were immunized with described vac-cines, then the growth of each tumor was measured;splenocyte proliferation of immunized mice was detected;and the cytotoxic effects of the vaccine on tumor cells were tested. After that, the in vivo concentrations of IFN-γ and anti-hVEGF antibodies were investigated by ELISA. The difference between each experimental group and normal saline group ( NS) was statistically significant in both tumor-bearing mouse models ( P <0. 05) respectively. Besides, VGC group exhibited significantly better anti-tumor effect compared with the GC and VC groups with the anti-tumor rate ( 41. 7 ± 0. 83)% and ( 46. 4 ± 1. 27)% for prostatic cancer and melanoma tumor, respectively. The co-administration of the two proteins, VC and GC, could inhibit the growth of RM-1 prostatic tumor and B16F10 melanoma effectively via anti-tumor immunity and anti-tumor angiogenesis.
