OBJECTIVETo explore the effect of emodin on endoplasmic reticulum (ER) stress of pancreatic acinar AR42J cells.
METHODRat pancreatic acinar AR42J cells were cultured in 6-well plates, and divided into the normal control group, the model group (with the final concentration at 1 x 10(-7) mol · L(-1) for cerulean and lipopolysaccharide at 10 mg · L(-1)) and the emodin group (10, 20, 40 μmol · L(-1)). Cells in each group were cultured in three multiple pores for 24 h, and their supernate was removed after cell attachment. The normal control group was added with haploids, the model group was added with the modeling liquid for haploids, and the treatment groups were added with different concentrations of emodin at 15-20 min before the modeling liquid. The cells were continuously cultured for 3 h under 37 °C and 5% CO2. Their intracellular protease and lipase expressions were detected with kits. The cellular morphology was observed under optical microscope. The level of calcium in endoplasmic reticulum was measured under laser confocal microscopy. Western blot assay were used to determine the protein expression of ER-related signaling molecules.
RESULTEmodin could significantly inhibit levels of amylase, lipase and intracellular calcium and ER.
CONCLUSIONEmodin could reduce pancreatic acinar cell injury induced by the combination of cerulean and lipopolysaccharide. Its action mechanism is correlated with the inhibition of intracellular calcium overload and ER stress.

Objective:To explore the application of OTSU-based self-attenuation correction PET (sacPET) reconstruction technology in 18F-florbetapir (AV45) imaging. Methods:From November 2018 to December 2019, 7 confirmed Alzheimer′s disease (AD) patients (4 males, 3 females, age (69.6±4.5)years) and 3 healthy controls (HC; 1 male, 2 females, age (68.0±4.6) years) were recruited prospectively for 18F-AV45 PET imaging in the First Affiliated Hospital of Sun Yat-Sen University. Original data collected by PET acquisition was processed with sacPET reconstruction and then compared with standard PET images by visual analysis and semi-quantitative analysis. Fisher exact test, Kappa test and Pearson correlation analysis were used to analyze data. Results:In HC group and AD group, the radioactive distribution showed by sacPET images and that by standard PET images were similar, and the contrast of gray-white matter in sacPET images was weaker than that in standard PET images. Moreover, the positive uptake area of the cortex in the AD group was smaller than that in standard PET images. Visual analysis showed 19 positive regions in sacPET images and 22 in standard PET images, with no statistical difference of positive rates of the sub-regions in the cortex between the two PET images (all P>0.05), and the overall consistency of 88.00% (44/50; Kappa=0.75 (95% CI: 0.57-0.94), P<0.05). Semi-quantitative analysis showed that the standardized uptake value ratio (SUVR) of frontal lobe and cingulate gyrus measured by sacPET was lower than that measured by standard PET (0.93±0.06 vs 0.96±0.06 and 0.99±0.04 vs 1.01±0.04; t values: 5.30 and 5.10, both P<0.01), while SUVR of parietal lobe, temporal lobe and occipital lobe measured by sacPET was higher than that measured by standard PET (0.78±0.08 vs 0.68±0.07, 0.97±0.07 vs 0.91±0.08 and 0.94±0.11 vs 0.71±0.12; t values: 6.27, 7.36 and 16.90, all P<0.01). The overall SUVR of sacPET images was significantly correlated with the standard PET images ( r=0.75, P<0.001). Conclusion:For 18F-AV45 imaging, sacPET reconstruction technology can obtain reliable and effective PET images without CT data, but its accuracy and precision still need to be improved.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.
