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.

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.

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.

Objective To assess the role of MRI in the preoperative characterization and local staging of testicular neoplasms.Methods A retrospective study of 24 patients suspected of testicular neoplasm was conducted.The histological diagnosis of testicular neoplasms was made and local extension of testicular malignancy was evaluated.The MRI findings were correlated with the pathologic results.Results Histological examination revealed 26 intratesticular lesions,14 of which were nalignant,including 4 cases of diffuse large B cell lymphoma,7 cases of seminoma,2 cases of embryonal carcinoma,one case of teratoma.Twelve lesions were benign,including 5 cases of epidermoid cyst,2 cases of simple cyst,2 cases of inflammatory granuloma,2 cases of testicular mediastinal tubular expansion and one case of testicular pseudo fibroma.Six malignant testicular tumors were confined within the testis,4 invaded the testicular tunicae or epididymis,2 invaded the spermatic cord,and 2 invaded the scrotal wall.The accuracy of MRI in the diagnosis of intratesticular lesions was 92％.The accuracy of MRI diagnosis in the local staging of testicular tunors was 86％.Conclusions MRI is highly accurate in the preoperative characterization and local staging of testicular neoplasms.It is of great significance to the clinical diagnosis and treatment.

Objective To analyze the clinic and imaging characteristics as well as development of intervertebral disc calcification in children.Methods 6 cases underwent intervertebral disc calcification.X-ray films and CT scan of cervical spine had been taken in all cases,two cases had MRI examination.All cases were followed-up for 2 to 3 years by radiograph and CT.Results Only one intervertebral disc involved in all cases.X-ray and CT findings included disc calcification,disc herniation and change of vertebral boy in form.The clinical symptoms disappeared after conservative therapy 2 to 4 weeks.But the disc calcification disappeared until 6 months to 3 years.Conclusion Intervertebral disc calcification in children is a self-limiting disease with excellent prognosis,its diagnosis depends on imageology.

Objective:To evaluate the clinical value of MR cholangiopancreatography(MRCP) as the only imaging procedure in diagnosing biliary complications after orthotopic liver transplantation(OLT).Methods: The MRCP results were analyzed in 54 consecutive patients presented with clinical or biochemical signs of biliary complications after receiving OLT,and were compared with the findings eventually confirmed by surgery,direct cholangiography,and clinical follow-up.Two different MRCP snapshot techniques were applied: thick-slab T_(2)-weighted sequences and multi-section thin-slab T_(2)-weighted sequences.Results: Surgery,direct cholangiography,and clinical follow-up confirmed that 36 patients had biliary complications.MRCP had a sensitivity of 100%(36/36) in diagnosing biliary complications after OLT,with a positive predictive value of 91.7%(33/36),a false-positive rate of 5.56%(2/36),and an overall diagnostic accuracy of 94.4%(51/54).MRCP as the only imaging procedure achieved a specific diagnosis in 96.3%(52/54) of the patients in the present study.Only 2 patients required additional endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholecystostomy.Direct cholangiography was required only as a therapeutic procedure in 25.9%(14/54) of the patients.Conclusion: MRCP is an effective imaging procedure in the assessment of biliary complications after OLT.Direct cholangiography is not needed for diagnosis but should be reserved as a therapeutic procedure.
