Considering the World Health Organization's classification of Helicobacter pylori as a definite (class I ) carci- nogen, the relationship between oral microbial community and tumors is gaining increased interest. This review focused on three relationships between oral microbiota and tumors, i.e., between oral Helicobacter pylori infection and gastric tumors, between oral microbiota and oral squamous cell carcinoma, and between human immunodeficiency virus and tumors. The aims were to realize the early diagnosis of tumors with oral microbiota and support studies on treatment development.

AIM: To study the effects of tetrandrine(Tet) and fructose-1,6-diphosphate(FDP) on the elevated intrasynaptosomal [Ca 2+ ] i induced by excitatory amino acids (EAA). METHODS: A rapid method for preparing synaptosomes was used, and intrasynaptosomal free calcium ([Ca 2+ ] i) was measured by using the fluorescent indicator quin-2. RESULTS: L-glutamate (Glu, 100 ?mol/L), aspartate (Asp, 100 ?mol?L -1 ), N-methy1-D-aspartate (100 ?mol/L) and Glu (50 ?mol/L) plus Asp (50 ?mol/L) all elevated intrasynaptosomal [Ca 2+ ] i in a dose-dependent manner. Pretreatment with Tet (10,30,60 ?mol/L) , FDP (15, 30, 75, 150 ?mol/L), MK-801 (10, 20 ?mol/L) and Tet (15, 30 ?mol/L) plus FDP(15, 30 ?mol/L) all attenuated the increase in intrasynaptosomal [Ca 2+ ] i induced by EAAs mentioned as above in a dose-dependent manner, and the effect of Tet plus FDP was most significant. CONCLUSION: Both Tet and FDP inhibited a rise in intrasynaptosomal [Ca 2+ ] i induced by EAAs, which may be one of mechanisms that Tet and FDP pretect cerebral tissues against ischemia injury.

Objective Improve understanding the clinical features of bladder varices with portal hypertension. Methods A 63-year-old male manifested seven episodes of painless gross hematuria and had a 9-year history of liver cirrhosis. Physical examination was unremarkable. There was thrombocytopenia of 56 × 109/L. Ultrasound showed splenomegaly. Cystoscopy revealed a 3. 0 cm × 5.0 cm sized hemangiomatous on the left lateral and anterior wall of the bladder. Computed tomography angiography revealed the vesical varicose veins flowing into the inferior mesenteric vein and then to the splenic vein. Results The patient was diagnosed vesical varices, liver cirrhosis and portal hypertension. Performed perivesical devascularization and in ultrasound one month after the operation the variees disappears. Conclusion Vesical varices can occur in liver cirrhosis and portal hypertension patients without history of abdominal and pelvic operation, and can be treated by perivesical devascularization.

Objective To detect the expression and correlation of serum Hepcidin,IL-6,sTfR,BMP6 diversity and explore the role of serum Hepcidin in prostate cancer with bone metastasis.Methods From January 2012 to March 2012,serum Hepcidin,IL-6,sTfR,BMP6 diversity were tested by ELISA in 25 prostate cancer patients with bone metastasis,30 prostate cancer patients without bone metastasis and 30 patients with BPH were used as the control group.The mean patient's age was 67 years (range from 55 to 75 years).In prostate cancers with bone metastasis group,the mean PSA base line was 138.0 μg/L (ranged from 20.0-1500 μg/L),the prostate cancers without bone metastasis group,mean PSA was 10.2 μg/L(ranged from 3.5-28.2 μg/L),and in BPH group,the mean PSA was 3.7 μg/L (ranged from 0.3-14.2 μg/L).Venous blood samples were taken in fasting mornings,then stored 3 ml in EDTA anticoagulant vacuum tube and centrifuged at4 ℃ for 10 min,the isolated serum were then preserved in-80 ℃ refrigerator.The competitive in-phase enzyme-linked immunoassay (ELISA) was used to detect serum Hepcidin,IL-6 and sTfR and BMP6 levels.Results Serum Hepcidin expressions in three groups were 67.7 ± 40.6 μg/L,37.5 ± 15.3 μg/L and 34.3 ± 10.7 μg/L,respectively.For prostate cancers with bone metastasis group,serum Hepcidin expression were higher than control group (P ＜ 0.05),and associated with IL-6(22.5 ±22.1 μg/L),sTfR (5.7 ± 2.6 μg/L),BMP6 (429.3 ± 188.4 μg/L),correlation coefficients were 0.972,-0.987,0.971 (P ＜ 0.05).Conclusions Increased serum Hepcidin level might be a sensitive index for diagnosis and prognosis of prostate cancers with bone metastasis.
