Objective: To explore the application value of real-time adenosine stress 3-dimensional echocardiography (3D-ASE) for diagnosing the patients with of coronary artery disease (CAD).
Methods: A total of 46 suspicious CAD patients were studied by 3D-ASE analysis. There were 26 male and 20 female patients from (38-73) years of age at the mean of (63.3 ± 7.2) years. Adenosine stress echocardiography was performed by infusing the agent at 140 ug/(kg?min) in 6 minutes. The changes of segmental ventricular wall motion, electrocardiogram (ECG), clinical symptoms, blood pressure and heart rate were recorded. Positive 3D-ASE result was deifned by the time of left ventricular segment minimum contraction volume gradually extending. Coronary angiograph (CAG) was conducted at 2 weeks after 3D-ASE, positive CAG ifnding was conifrmed by at least one of three main branches with the stenosis≥50%.
Results: There were 29/46 patients with positive CAG findings, 26 with positive 3D-ASE presentations and 8 with positive adenosines tress ECG. CAG showed that 48 coronary branches were positive and 90 were negative;3D-ASE indicated that 40 coronary branches were positive and 98 were negative. For 3D-ASE diagnosed coronary lesions, the overall sensitivity was 89.6%(26/29), speciifcity 76.5%(13/17), accuracy 84.8%(39/46). There were 36 branch lesions conifrmed by both CAG and 3D-ASE. For 3D-ASE determined coronary lesions, the sensitivity was 75%(36/48), speciifcity 95.6%(86/90), accuracy 88.4%(122/138). For 3D-ASE found single, double and three vessels diseases, the sensitivities were 60%(9/15), 88.9%(8/9) and 100%(5/5) respectively. The e occurrence rate of 3D-ASE side effect was 52.2%, there were usually slight symptoms without severe adverse reaction.
Conclusion: 3D-ASE has the high sensitivity and speciifcity in CAD diagnosis, it is an non-invasive examination with slight side effect, and therefore, has an important application value in clinical practice.

AIM: To establish the hyperlipemic rat model by long-term gastric perfusion of intralipid and investigate the effects of hyperlipidemia on bone. METHODS: Eighteen SD rats were randomly divided into control group (C) and high-fat-diet group (HDF), with 9 rats per group. Rats of C group were treated orally with normal saline, and rats in HDF group were oral gavage of intralipid at dose of 5.0 mL/kg, once a day for 20 weeks. At the end of experiment, their serum levels of lipid were measured. Bone histomorphometric analysis of thighbone was performed in undecalcified sections, and the length and width of ulnar were measured. RESULTS: Compared with the C group, serum TC and low density lipoproteins (LDL) were increased (P

Objective To compare the differences of clinical characteristics between genotype B and C chronic hepatitis B(CHB)patients and to summarize clinical factors related to genotype C hepa- titis B virus(HBV)infection.Methods Seventy eight CHB patients who were diagnosed with genotype B or C infection by liver puncture biopsy and genotyping were enrolled.Their serum HBV DNA levels were detected.Severe hepatitis,liver cirrhosis,hepatocellular carcinoma and HBeAg positive rate were analyzed to determine the pathologic inflammation and fibrosis degree of liver tissue.Chi square test and Logistic multiple regression analysis were employed for the statistical analysis.Results The serum albumin and pre-protein were lower in genotype C CHB patients than that in genotype B.The alanine aminotrans- ferase,total bilirubin and prothrombin time were higher in genotype C CHB patients than that in genotype B.The rates of genotype C patients increased significantly with the grade of liver necroin- flammation progressing from GO to G4(1.8%,11.1%,20.4%,33.3%,33.3%) and the stage of liver fibrosis progressing from SO to S4(5.6%,5.6%,14.8%,33.3%,40.7%),but the rates of genotype B patients did not change significantly with the grade of liver necroinflammation(16.7%, 25.0%,25.0%,20.8%,12.5%)and stage of liver fibrosis progressing(16.7%,29.2%%,20.8%, 16.7%,16.7%).There was statistical significance in grades of liver necroinflammation(X~2= 11.49,P=0.022)and stages of liver fibrosis(X~2=13.56,P=0.006)between genotype B and gen- otype C patients.The rates of genotype C CHB patients were higher than,similar with and lower than the rates of genotype B patients of HBV DNA level above 1.0?10~6 copy/mL,between 5.0?10~2-1.0?10~6 copy/mL and under 5.0?10~2 copy/mL,respectively(51.8% vs 12.5%,35.2% vs 45.8% and 13.0% vs 41.7%).There was statistical significance of HBV loads between genotype B and genotype C patients(X~2=13.25,P=0.001).HBeAg positive rate in genotype C patients was significantly higher than that in genotype B patients(61.1% vs 25.0%,X~2=8.67,P=0.003).The rates of decompensated cirrhosis,compensated cirrhosis and no-cirrhosis in genotype C patients were higher than,similiar with and lower than the rates in genotype B patients,respectively(40.7% vs 4.2%,22.2% vs 20.8% and 37.0% vs 75.0%).There was statistical significance of the rate of cirrhosis between genotype B and genotype C patients (X~2=12.47,P=0.002).Conclusions The degree of liver necroinflammation and fibrosis,the HBeAg positive rate and the incidence of cirrhosis are all related with genotype C HBV infection.

Objective To evaluate the feasibility and effectiveness of combination chemotherapy with etoposide and cisplatin(EP)regimen on the patients with high-risk,chemorefractory and recurrent gestational trophoblastic neoplasia(GTN).Methods Thirty-nine patients with gestational trophoblastic tumors were analyzed retrospectively,25 of 39 patients were of high-risk,9 patients were chemorefractory and 5 patients were recurrent.All 39 patients were administrated with EP regimen,and 10 patients were assisted with surgery.All the patients were followed up.Clinical response,toxicity,the occurrence of secondary tumors of all patients,and the fertility of 30 patients whose fertility function was preserved were investigated. Results Thirty-nine GTN patients underwent a total of 221 cycles of the EP regimen.The average number of courses for each patient was 5.7.The total complete remission rate of the regimen was 74%(29/39). Twenty-five patients with high-risk GTN received a total of 139 cycles and the average number of courses was 5.6.Nineteen patients achieved complete remission and 6 patients showed drug-resistant.The complete remission rate of the high-risk group was 76%(19/25).Nine patients with chemorefractory GTN obtained a total of 55 cycles and the average number of courses was 6.1.Six patients achieved complete remission and 3 patients showed drug-resistant again.The complete remission rate of the chemorefractory group was 6/9. Five patients with recurrent GTN received 27 cycles and the average number of courses was 5.4.Four patients achieved complete remission,1 patient showed drug-resistance and died.Bone marrow toxicity, gastrointestinal reaction and alopecia were the main side effects of the EP regimen,but the bone marrow toxicity was slight and no grade Ⅳ side effect occurred.No fatal effect was found.Eight of 30 patients whose fertility faction was preserved had become pregnant after recovery,with a total of 8 pregnancies.Among them,2 were terminated by induced abortion,and 6 underwent normal term delivery and gained 6 infants who had no congenital malformation.All the 6 children had normal growth and development after childbirth. None of the women developed secondary tumors.Conclusion The EP regimen is effective and safe for the treatment of high-risk,chemorefractory and recurrent GTN.
