Objective: To evaluate the diagnostic value of IL-6,IL-8,and TNF-? in malignant pleural effusion and tuberculous pleural effusion.Methods:We detected IL-6,IL-8,and TNF-? in malignant pleural effusion(21 cases)and tuberculous pleural effusion(13cases).Results:The mean values of the three cytokines measured in tuberculous pleural effusion were significantly higher than malignant pleural effusion( P

Objective:To implove the level of diagnosis and treatment of renal tuberculosis complicated with active pulmonary tuberculosis.MethodsThe diagnosis and treatment of 28 cases with renal tuberculosis complicated with active pulmonary tuberculosis were analyzed.Results:88.2% of patients were negative in PPD test, and 55.6% positive in the sputum acid fast stain. All the patients except 4 received thetreatment of anti-tuberculosis continuosly for 3-6 months before surgery.Conclusion:It is necessary to treat the patients with anti-tuberculosis drugs and improve their immune function before proper surgical treatment.Patients in fair general condition could be operated on 2 weeks after anti-tuberculosis therapy.

Objective To study the related factors of coronary no-reflow phenomenon in H-hypertensive acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI).Methods 120 AMI patients were selected as the study subjects,all patients were given PCI,the infarct-related coronary artery stenosis forward flow(TIMI) grade ≦ 2 level was the no-flow criteria.The patients were divided into two groups:the no-reflow group (35 patients),the other 85 cases classified as normal blood group.The age,gender,body mass index (BMI),history of diabetes,hyperlipidemia hyperlipidemia history,family history,blood glucose,homocysteine (Hcy),white blood cell count,C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),creatine kinase (CK),creatine kinase (CK-MB),triglycerides,total cholesterol,high density lipoprotein (HDL),low density lipoprotein (LDL),troponin-Ⅰ (cTn-Ⅰ),treatment time and other factors were observed and compared.Logistic regression analysis was used to identify relevant factors of no-reflow.Results 120 patients with primary PCI,no-reflow in 35 patients,the incidence rate was 30.1％.The sex,smoking history,history of hyperlipidemia,diabetes,history of angina,and Killip classification before treatment,time from chest pain to before treatment between no-reflow patients and normal blood flow patients had no significant differences (t =1.275,P ＞ 0.05).Multivariate Logistic regression analysis showed that:age,diabetes,triglycerides,HCY,cTn-Ⅰ,CK-MB,CRP were related factors of no-reflow(t =3.427,P ＜ 0.05).Conclusion Age,without pre-infarction history of angina,coronary artery open long hours,admission NYHA low,white blood cell count high,CK-MB and cTn-Ⅰ levels higher are independent risk factors of no-reflow phenomenon,PCI with no-reflow phenomenon indicates the poor prognosis.

ObjectiveTo investigate the clinical value ofDNA ploidy analysis in the diagnosis of benign and malignant pleural effusion.MethodsDNA ploidy in 24 benign pleural effusion and 39 malignant pleural effusion were detected by flow cytometry (FCM) and compared with the results of cytologic detection at the same time.ResultsThe positive rates of FCM detection in benign and malignant pleural effusion were 8.33％(2/24) and 64.10％ (25/39),there was significant difference (P＜0.05).The positive rates of cytologic detection in benign and malignant pleural effusion were 4.17％( 1/24 ) and 53.85％( 21/39),there was significant difference (P＜0.05).The sensitivity of FCM and cytologic detection in malignant pleural effusion was 64.10％ (25/39) and 53.85％ (21/39),the specificity of two methods was 91.67％ (22/24) and 95.83％ (23/24.),the results of two methods showed no significant differences (P ＞0.05).ConclusionDNA ploidy analysis by FCM has important clinical value in the diagnosis of benign and malignant pleural effusion.

The study of brain information flow is of great significance to understand brain function in the field of neuroscience. The Granger causality is widely used functional connectivity analysis using multivariate autoregressive model based on the predicted mechanism. High resolution electroencephalogram (EEG) signals of ten healthy subjects were collected with a visual selective attention task. Firstly, independent component analysis was used to extract three spatially independent components of the occipital, parietal, and frontal cortices. Secondly, the Granger causal connectivity was computed between these three regions based on the Granger causality method and then independent sample t-test and bootstrap were used to test the significance of connections. The results showed that Granger causal connectivity existed from frontal to occipital and from parietal to occipital in attentional condition, while causal connectivity from frontal to occipital disappeared in unattentional condition.

A method was developed for the determination of 39 polybrominated diphenyl ethers(PBDEs) from mono- to hepta-brominated in coastal sediment by gas chromatography/mass spectrometry. The sample was extracted with a solution of dichloromethane: n-hexane( 1:1,V/V) ,followed by ultrasonic extraction for 60 min at 25℃. The clean-up step was optimized using silica gel and alumina. The detection limit of the method was in the range of 0.003 - 0.10μg/kg. The results indicate that the average recovery of the internal standard was from 66.2% to 118. 6%. The relative standard deviation RSD( % ) was from 0. 8 % to 18. 2%. The method for the detection of 39 PBDE congeners in coastal sediment was sensitive,high reproducible with satisfactory recoveries.

International League Against Epilepsy announced the new International Classification of Epilepsy in 2001. One of the main objectives of the project is to adopt standard terms to describe seizure phenomena according to the terminological database. The project may profit academic communication and resource integration, and provide evidence for the individual treatment for epilepsy. Treatment based on syndrome differentiation is one of the characteristics of the treatment for epilepsy in traditional Chinese medicine (TCM). As far as the individuation on diagnosis and treatment is concerned, TCM and Western medicine present to reach the same goal by different routes gradually for the treatment of epilepsy. But for TCM, the diagnosis and treatment criteria for epilepsy are imperfect and the experts, opinions are not unified, so that the treatment based on syndrome differentiation becomes confused, hence the credit of treatment based on TCM is restricted accordingly. It is necessary to formulate advanced diagnosis and treatment criteria for syndromes of epilepsy in TCM.

The artical analyzes the problems existing in the aspects of textbooks,teaching outlines,qualified teachers and students'attitude and puts forward some corresponding solutions in the hope of arousing the recognition of the academy and departments concerned.

Objective To investigate CT and MRI findings of primary hepatic neuroendocrine tumor (PHNET) and the correlation with the pathology.Methods 14 patients with pathologically confirmed PHNET were analyzed retrospectively.All the patients underwent CT and 9 patients underwent MR.The CT and MRI findings were analyzed and the correlation with pathology was evaluated.Results Single lesion was found in 8 cases, and multiple nodular lesions in 5 cases, diffuse nodular lesions of the liver in 1 case.The lesions showed low density on CT images in all patients, and liquid-liquid level was visible in 1 lesion associated with internal bleeding.Contrast-enhanced CT in arterial-phase phase showed nodular or marginal ring enhancement in 13 cases, diffuse enhancement in 1 case, and in portal venous and delayed phases the enhancement of lesion subsequently decreased, compared with surrounding liver parenchyma.MRI showed hypointensity on T1WI and hyperintensity on T2WI, intralesional hemorrhage appeared as hyperintensity on T1WI and hypointensity on T2WI, and the enhancement pattern of MRI was similar to that of CT.With the increase of pathology grade,G1 presented as a single solid nodule,G2 as solid or cystic-solid nodules, and G3 as diffuse nodules or intrahepatic metastasis was found.The lesions showed hyperintensity on DWI.Conclusion CT and MRI can show characteristic appearances of PHNET and its certain histological characteristics.
