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.

Innovation of cultivation mode and concepts for medical English should be suited to the requirements of making university academically outstanding by its individualized school-running,requirements of strengthening distinguished majors as well as needs for qualified medical English graduates.Through combining undergraduate tutorial system of lower grades with undergraduate tutorial system of higher grades,continuing implementing concepts of team cooperation,strengthening holistic education concept and guiding the development of students' individual personality and academic study based on stages,tutors and tutorial team can play their central roles in the training and molding of qualified medical English undergraduates,ultimately realizing the unity of process cultivation and objective cultivation.
