Objective To explore the value of two-dimensional strain echocardiography for quantitative assessing the change of regional left ventricular myocardial function in rats following acute myocardial infarction. Methods Sixty Wistar rats were randomly divided into two groups. The study group consisted of 50 rats with occlusion of LAD for 30-45 minutes and the sham-operated group consisted of 10 rats without occlusion of LAD. Echocardiography were performed before operation, which was defined as baseline, and 1 week, 4 weeks and 8 weeks after operation. Left ventricular internal diameter at diastole ( LVIDd) and systole < LVIDs), fractional shortening( FS), ejection fraction (EF) and left ventricular mass(LVM) were measured by anatomical M-model echocardiography. High frame rate two-dimensional images were recorded in the left ventricular short-axis views at the papillary muscle level. Peak systolic radial strain(PRS) and circumferential strain(PCS) of each segment were measured using 2-dimensional strain software. The rats were sacrificed and the infarcted size of each segment was measured using triphenyl tetrazolium chloride (TTC) after echocardiography was performed. Fibrosis of left ventricular myocardium was displayed using Van Gieson stain in 1 weeks after infarction. Results Based on the TTC findings,the left ventricle of the study group was divided into three regions:infarcted,peri-infarct and remote myocardial regions. Van Gieson stain showed fibrosis existed in all the three regions. Compared with baseline and sham-operated group, PRS and PCS of infarcted, peri-infarct and remote myocardial regions of the study group significantly decreased within 1 week after operation ( P <0. 01) and persisted for 8 weeks. PCS and PRS of infarcted, peri-infarct and remote myocardial regions of the study group in 4 weeks and 8 weeks after operation showed no significant difference when compared with those in 1 week after operation ( P >0. 01). Compared with baseline and sham-operated group,LVIDd,LVIDs and LVM of study group all increased significantly ( P <0. 05) in 4 weeks and 8 weeks after operation,and FS and EF reduced significantly ( P <0. 05). Two-dimensional strain obtained in interobserver and intraobserver both showed high agreement. Conclusions Two-dimensional strain echocardiography can assess regional function of myocardium with different perfusion in rats following acute myocardial infarction, and provides a sensitive and reliable method to follow up the process of left ventricular remodeling after myocardial infarction.

Objective To observe the value of two-dimensional speckle tracking imaging (2D-STI) in assessing regional myocardial viability of rats after acute myocardial infarction. Methods Twenty Wistar rats were randomly divided into acute myocardial infarction group and sham-operation group (each n=10). Echocardiography was performed at baseline and 24 h after reperfusion. High frame rate two-dimensional images were recorded from the left ventricular short-axis views at the papillary muscle level. Peak radial strain (PRS) and peak circumferential strain (PCS) of each segment were measured at systolic period. Left ventricular internal diameter at diastole (LVID_d) and systole (LVID_s), fractional shortening (FS), ejection fraction (EF), wall thickening rate (TR) were measured with anatomical M-model echocardiography. Area of necrosis (AN) of each segment was measured after triphenyl tetrazolium chloride (TTC) staining. Based on TTC staining, ROC curve was used to analyze the accuracy of two-dimensional strain and TR index in identifying infarcted segment. Results ①Compared with acute myocardial infarction group at baseline and sham-operation group after operation, LVID_d and LVID_s of acute myocardial infarction group after operation increased significantly respectively (P<0.05), FS, EF and anteroseptal wall TR reduced significantly (P<0.05). ②Compared with acute myocardial infarction group at baseline and sham-operation group after operation, PRS and PCS decreased significantly in anteroseptal, anterior, anterolateral, inferolateral and inferoseptal segments of myocardial infarction group after operation (P<0.05), especially in anterosepetal, anterior and anterolateral segments (P<0.05). ③ROC analysis showed PCS had the best ability to identify infarcted myocardium as defined by AN>50%. Using a cut-off of -6.14%, PCS had a sensitivity of 93.75% and specificity of 90.91% for distinguishing infarcted from viable myocardium. Conclusion 2D-STI can accurately quantify regional myocardial function, providing a sensitive and noninvasive means to assess regional myocardial viability.

To investigate the adjuvant effect of plasmid DNA encoding superantigen SEA (D227A) (pmSEA) on immune responses induced by HBV DNA vaccine containing HBV preS2 and S antigen in BABL/c (H-2d). BALB/c mice were immunized intramuscular injection with HBV DNA vaccine (pHBVS2S) mixed with or without pmSEA plasmid. Antibodies againat HBV PreS2 and S antigen in the sera were accessed by Anti-HBs ELISA, and the HBsAg specific cytotoxic T lymphocytes (CTLs) activity was determined by 5 Chromium Release Assay. The HBs peptide-specific IFN-gamma secreting T cells were detected by ELISPOT. Anti-HBs antibody titers and CTLs activity in mice immunized with pmSEA + pHBVS2S group were significant higher (P < 0.05) than pHBVS2S DNA vaccine group. The ratio of IgG1/IgG2a (0.282) was apparently different from the group immunized with peptide (10). Mice immunized with HBV DNA vaccine plus adjuvant produce higher titer of IgG1 and IgG2a antibodies against HBV S antigen 1.36 and 1.73 time higher than that without adjuvant respectively. HBs peptide--specific IFN-gamma secreting T cells increased 2 - 3 times by the pmSEA adjuvant, compared to DNA vaccine group. HBV DNA vaccine (pHBVS2S) induces humoral and cellular immuno-responses in BALB/c mice, and the responses could be significantly boasted by the plasmid encoding mSEA. Therefore the pmSEA was a potential adjuvant for DNA vaccines.

Objective To assess the therapeutic effect of arterial embolization with ONYX-18 for treatment of tentorial dural arteriovenous fistula (DAVFs). Methods The clinical data (including the disease history, radiographic examination, surgical record, and follow-up data) of 4 patients with DAVF treated between March and July, 2008 were retrospectively analyzed. Of the 4 patients, one had acute subaraclmoid hemorrhage, and 3 exhibited progressive neurological deficits. The fistula orifice was located on the top of the tentorium in 2 cases, on the left tentorium in one case and in the posterior tentorium in the other. Type Ⅱ b DAVF was found in 2 cases, type Ⅲ in one case and type IV in the other ease. All the 4 patients underwent arterial embolization with ONYX-18, with ONYX-18 dose of 1.5, 3.5, 9, and 12 mL, respectively. One patient underwent ventricuioperitoneal shunt after the embolization because of obstructive hydrocephalus. Results The fistulae were embolized completely in 3 cases, and in one patient, a small quantity of blood supply to the fistula orifice was present fi'om the occipital artery, but the blood flow velocity was obviously reduced. Follow-up of the patients for 3 months revealed no occurrence of the former symptoms after the embolization. Conclusion ONYX-18 injection through one single feeding artery after placement of the micro-catheter at the appropriate position allows effective embolization of the fistula orifice, the supplying arteries and the venous ends to achieve safe and effective embolization of DAVF.
