Objective To discuss the value of CT prognosis on the Masaoka staging system of thymic epithelial tumors(TET) before surgical resection.Methods The CT images of 102 patients with TET proved by surgery and pathology were reviewed retrospectively.The TET were reclassified according to Masaoka stage system.The size,homogeneity,sharp,contour,infiltration of surrounding tissue,and metastasis on CT were analyzed with Logistic analysis.The diagnostic value was also evaluated with a ROC curve.Results Masaoka pathologic stages were stage Ⅰ for 36 (35.3 ％),stage Ⅱ for 27 (26.5 ％),stage Ⅲ for 30 (29.4 ％),and stage Ⅳ for 9 (8.8 ％).A multivariable Logistic regression model showed that TET with larger size of tumor (20/35,P =0.0371,OR =4.539),irregular or lobulated tumor contour (26/42,P =0.0230,OR =4.870),heterogeneous (21/33,P =0.0154,OR =6.020),infiltration of surrounding fat (25/32,P =0.0019,OR =14.005),and pleural seeding (11/11,P =0.0032,OR =36.153)were more likely to have stage Ⅲ or Ⅳ disease.The area under ROC curve was 0.940.Conclusions The tumor CT imaging features can differentiate between stage Ⅰ,Ⅱ and stage Ⅲ,Ⅳ disease.This helps identified patients more likely to benefit from neoadjuvant therapy.

Objective To study the imaging features of the ventricular meningioma, in order to improve the understanding knowledge. Methods Compared with operative and pathological findings,the CT and MRI features of ventricular meningioma were analyzed in 22 patients (8 males and 14 females,range from 17~72 years old with average age 45 years).21 cases were examined by MRI(17 with enhanced scan),11 cases by CT(4 with enhanced scan).Results The ventricular meningioma were mostly fibrous type. Mostly, the locations were in the trigone of the lateral ventricle with regular shape. On imaging, the most were parenchymatous with markedly enhancement. Calcification may be found, but cystic changes and hemorrhage were very rare.Conclusion The ventricular meningiomas have characteristic imaging features. CT and MRI are valuable in diagnosis, especially MRI.

Objective:To study the reasons and preventive measure of the effect of human urinary kallikrein on blood pressure in the treatment of acute cerebral infarction.Method:Documents about the effect of human urinary kallikrein on blood pressure of pre-clinical study and the phaseⅠ-Ⅲclinical trials were collected and analyzed in combination with the related information of the phaseⅣclinical trial from our hospital.Result:The rate and concentration of medication in combination with ACEI were the reasons for the effect of human urinary kallikrein on blood pressure.Conclusion:Controlling the rate and concentration of medication and forbidding the combined use of ACEI from the 72hr before the medication and the 24hr after it can prevent hypotension caused by human urinary kallikrein.

Objective To study the imaging features and the cause of the cystic meningiomas so as to avoid the misdiagnosis and improve the understanding and knowledge. Methods CT and MRI features in 27 pathologically proved cystic meningiomas were analyzed. There were 10 men and 17 women, and the age ranged from 16 to 80 years with the average age of 49 years. Twenty-six patients were examined by using MRI (24 with enhanced scan), and 15 patients by CT (seven with enhanced scan). 15 patients were examined by both CT and MRI. The image features were analyzed according to Nauta and were compared with operative and pathological findings. Results The cystic meningiomas were mostly epithelial type, but fibrous type, angiomatous type, or papillary type may also be seen. Mostly, the locations were cerebral convexity, but tumors of the tentorium, alisphenoid, olfactory groove, and skull base were also seen. And all were sessile. On imaging, most tumors were parenchymatous with cystic parts, and marked enhancement of the parenchymatous part could be seen. Some were entirely cystic with parenchymatous nodule, the nodule enhanced markedly and the wall of the cyst may be or not be enhanced. Of the 27 cases, four cases were NautaⅠ, seven cases were NautaⅡ, one case was Nauta Ⅲ, and ten cases were Nauta Ⅳ. Three were both Nauta Ⅱand Ⅲ in 3 cases, Nauta Ⅱ, Ⅲ, and Ⅳ in 1 and both Nauta Ⅲ and Ⅳ in 1, respectively. Conclusion The cystic meningiomas have characteristic imaging features. CT and MRI, especially MRI, are valuable in the diagnosis.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

Objective To investigate the relationship between blood pressure(BP) and prognosis in three different ischemic stroke subtypes.Methods The consecutive patients with a brain infarction proven on diffusion-weighted MRI who were hospitalized within 48 hours after stroke onset between April 2007 and April 2008 were registered.All subjects with acute ischemic stroke consecutively admitted to the neurological wards of the First Affiliated Hospital of Wenzhou Medical College,were registered in the Wenzhou Stroke Registry Program.Data were collected and coded at primary registration.The BP levels were studied during the initial 7 hospital days.Survival and dependency were assessed at 3 months.Outcomes were adjusted age,consciousness level,admission NIHSS score,the decline level of systolic BP,the decline level of diastolic BP,complication and so on. Logistic regression model was used to estimate the relationship between BP and prognosis.Results A U-shaped effect was observed in each subgroup between BP and prognosis.In the subgroups of atherothrombosis,cardioembolism and small artery disease,those who had a BP of 150/95 mm Hg(1 mm Hg=0.133 kPa)on admission,140/90 mm Hg on day 1-7 would have a better prognosis.In the subgroups of atherothrombosis and cardioembolism,the decrease of BP during the first 24 hours was the independent predictor of the death and disability at 3-month.In the atherothrombosis group,when the decrease of systolic BP during the first 24 hours was greater than 20 mm Hg,the risk of the death and disability at 3-month increased 4.44 times(OR 4.44,95%CI 1.70-11.59,P=0.002).In the atherothrombosis group,when the decrease of diastolic BP during the first 24 hours was greater than 10 mm Hg,the risk of the death/disability at 3-month increased 3.70 times(OR 3.70,95%CI 1.54-8.90.P=0.00).In the cardioembolism group,the risk increased respectively 7.98 times(OR 7.98,95%CI 1.34-47.66.P=0.026)and 6.68 times(OR 6.68.95%CI 1.55-28.79,P=0.01).In the subgroups of small artery disease,the decrease of BP during the first 24 hours was not the independent predictor of the death and disability at 3-month.Conclusions A U-shaped effect is observed in each subgroup between BP and prognosis.In the subgroups of atherothrombosis and cardioembolism,the decrease of BP during the first 24 hours is the independent predictor of the death and disability at 3-month.

AIM: To facilitate the suicide gene delivery into neoplasm, a chimeric gene of HSV-tk and green fluorescent protein (gfp) was constructed. METHODS: Molecular cloning technique was used to construct this kind of eukaryotic vector. The internal ribosome entry site (IRES) of encephalomyocarditis virus (EMCV), which could coordinate expression of two genes in a single vector, was optioned. By using liposome-mediated transfection, eukaryotic expression vector tgCMV/hytk-IRES-gfp was transfected into human bladder carcinoma cells EJ. RESULTS: A bicistronic eukaryotic vector carrying gfp and hygromycin phosphotransferase-thymidine kinase fusion (hytk) gene was constructed. The results of PCR and microscopy detection show that the hytk-IRES-gfp gene was successfully transferred into EJ cells. There were no differences in the growth pattern or the morphology between EJ and EJ/hytk-GFP cells. In vitro experiments demonstrated dose- and time-dependent cell killing by transduction of the hytk-IRES-gfp gene followed by GCV treatment. The IC50 (the concentration required to elicit 50% growth inhibition) was 2.16 mg/L in treatment with GCV for 72 hours. CONCLUSION: These results suggest that this new kind of eukaryotic vector could serves as a new tool and method for neoplasm gene therapy.
