Aim To investigate the protective effects of YXETNZ injection on SH-SY5 Y cells damaged by oxygen-glucose deprivation ( OGD ) , and explore its functional mechanisms. Methods After 4 h of OGD, the cells were treated with 25 mg·L-1 drugs for 1 h. Subsequently, cell viabilities were measured by cell counting kit-8 ( CCK-8 kit ) and cell apoptosis was measured by caspase-3/7 assay kit according to manu-facturer’ s instructions. Furthermore, cell death was also detected by ELISA. The levels of phospho-Akt, phospho-PKA,phospho-Bad were evaluated by western blot. Results Oxygen-glucose deprivation significant-ly decreased the cell viabilities of SH-SY5Y cells, while YXETNZ injection significantly increased cell vi-abilities, phospho-Akt, phospho-PKA and phospho-Bad. Furthermore, YXETNZ injection also reduced the activities of caspase-3/7 and cytoplasmic histone-asso-ciated-DNA-fragments contents. Conclusion Our re-searches demonstrat that YXETNZ injection shows good neuroprotective effects on SH-SY5 Y cells after oxygen-glucose deprivation. The underlying mechanisms may be associated with activation of PI3 K/Akt/Bad/caspase-3/7 , cAMP/PKA/Bad/caspase-3/7 signaling pathway.

Objective To investigate the value of high-dose dobutamine stress echocardiography combined with two-dimensional strain imaging in early diagnosis of coronary artery disease. Methods Highdose dobutamine stress echocardiography was performed to 28 patients with suspected coronary artery disease. All wall movements were observed during resting condition and at all stress levels,respectively;the peak systolic longitudinal strain in each endomyocardial segment of left ventricular was measured; the sensitivity and specificity between visual method and two-dimensional strain imaging in diagnosing myocardial ischemia with high-dose dobutamine stress echocardiography were compared. The average peak systolic longitudinal strain was calculated against control group, coronary artery disease group during ischemia segments and non-ischemia segments, and a comparison was made inside each group as well as against the other groups. The area under receiver operating characteristic curve of the peak systolic longitudinal strain was used to predict the sensitivity and the specificity of myocardial ischemia. Results With dobutamine dose of 40 μg·kg-1 · min-1 ,wall motion abnormalities were diagnosed in 6 patients (20 segments) through visual method, myocardial ischemia was found in 15 patients (148 segments) through computing the peak systolic longitudinal strain. Inside the coronary artery disease group during ischemic segments,the majority of peak systolic longitudinal strain was significantly reduced ( P<0.05) compared to the non-ischemic segments and the control group. In diagnosing myocardial ischemia in high-dose dobutamine stress echocardiography, the sensitivity of visual method and two-dimensional strain imaging were 35.3% and 88.2%(P<0.01), specificity 100% and 100%(P>0.05), and accuracy 60.7% and 92.8% (P<0.01). The cutoff value of the peak systolic longitudinal strain was less than or equal to 14.9%, its sensitivity and specificity in predicting myocardial ischemia were 83.3% and 91.7%,respectively. Conclusions High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can increase the sensitivity of detecting myocardial ischemia and detect concealed myocardial ischemia. High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can be used in early diagnosis of coronary artery disease.

This study was aimed to screen main active site to reduce blood lipid from Xin-Mai (XM) capsule and establish HPLC fingerprint of the site, in order to study the correlativity between active site and relevant fractions of its herbs. Solvent extraction was used to separate XM capsule into different polar fractions. Intraperitoneal injection of 75% egg-yolk emulsion was used to establish mice hyperlipidemia models. And the active site was screened. Chromatographic fingerprints of the site and relevant fractions of its herbs were configured by HPLC analysis. The
retention time of peaks was utilized as index to evaluate the correlativity. The results showed that lipid-lowering effect of ethyl acetate extract and garlic essential oil was significant (P<0.01). Fingerprint of the active site in XM capsule was established with 28 fingerprint peaks and the assignment results of 27 peaks were indicated. It was concluded that the active sites to reduce blood lipid of XM capsule were ethyl acetate extract and garlic essential oil. The established fingerprint method can effectively determine the correlativity between the active site and its relevant fractions, which contributed to pharmacodynamic material foundation and quality standard.

Objective To evaluate the relationship between carotid plaque neovascularization and coronary heart disease using contrast-enhanced ultrasound. Methods We studied carotid plaques in 312 patients with coronary artery disease by contrast-enhanced ultrasound [51 patients with acute coronary syndrome (ACS) and 261 patients with stable coronary artery disease (sCAD) ]. We analyzed sonographic features of each plaque, including the enhancement intensity of plaque (A value), the ratio of plaque to carotid artery lumen in enhancement intensity (Ratio), plaque thickness and plaque echo (soft plaque, hard plaque, mixed plaque, calcified plaque). Results The average thickness of plaque in patients with ACS and in patients with sCAD had no significant difference in statistics [(2.6±0.4) mm vs (2.9±0.8) mm, t=-1.903, P=0.058) ]. The group with ACS:soft plaque 43 (84.3%, 43/51), mixed plaque 8 (15.7%,8/51), no hard plaque and calcified plaque. And the group with sCAD:soft plaque 174 (66.7%,174/261), hard plaque 19 (7.3%,19/261), mixed plaques 16 (6.1%,16/261), calcified plaque 52 (19.9%,52/261). The percentage of soft plaque in the acute coronary syndrome group was significantly higher than that in stable coronary artery disease group (χ2=6.274,P=0.012). The A value and Ratio in patients with ACS were prominently larger than those in patients with sCAD [ (11.3±3.2) vs (8.9±3.3) dB, t=7.150,P<0.01;0.6±0.2 vs 0.4±0.2, t=7.419,P<0.01].Conclusion Carotid artery plaque neovascularization density was significantly higher in patients with ACS than that in patients with sCAD by using contrast-enhanced ultrasound, revealing that the neovascularization density is closely related to clinical symptoms of patients with coronary heart disease.
