ABSTRACT
Objective@#To study the intracellular location and characteristic of SFTSV NP protein in different phases using mini singlet oxygen generator (miniSOG) labeling technique.@*Methods@#MiniSOG is a recently-invented genetically-encoded tag for EM. MiniSOG-fused SFTSV NP (NPSOG) gene was cloned by PCR, and inserted into pcDNA3.0 plasmid to form pTPL-NPSOG, which was used to transfect 293 cells. The transfected cells of different phases were fixed in 2.5% glutaraldehyde in situ, stained with DAB through the photooxidation activity of miniSOG, and used to prepare ultrathin sections. Intracellular location and characteristic of SFTSV NP protein in different phases were studied by observing the sections under transmission electron microscope.@*Results@#After transfecting the plasmid with NPSOG to 293 cells, NP protein was expressed in cytoplasm and peri nucleus, and gradually aggregated, which connected with endoplasmic reticulum and Golgi apparatus to form larger volume and irregular inclusion bodies in cytoplasm. No obvious subcellular structure changes were found.@*Conclusions@#The SFTSV nucleoprotein can be expressed separately to form inclusion bodies without the assistance of other viral proteins. The formation of inclusion bodies requires the directional movement and aggregation of a certain number of NP proteins, which may involve the interaction of NP protein and host organelles during this period.

ABSTRACT
A new method for the rapid determination of total phthalates (PAEs) in edible oils was developed. The PAEs in edible oils all were hydrolyzed to phthalic acid with tetrabutylammonium chloride (TBAC) as catalyst. Then phthalic acid was extracted by the supramolecular solvent ( SUPRAS) made up of octanol, tetrahydrofuran and aqueous solution, and detected by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS / MS). As a result, hydrolysis time was 10 min. The linear range of phthalic acid was 0. 05- 2. 0 mg / L with a good correlation coefficients ( r > 0. 999). The limits of detection ( LOD) and quantification (LOQ) were 5. 41 and 18. 05 μg / kg, respectively. The recoveries of target analyte at three spiked levels were in the range of 84. 6% - 104. 5% . The repeatability, expressed as relative standard deviation (RSD), was 2. 6% for intra-day and 3. 7% for inter-day. The total PAEs content of 12 edible oils was found in the range of 0. 30-1. 09 mg / kg.
ABSTRACT
Objective To investigate the clinicopathological features of gastric cardia cancer with neuroendo-crine cell differentiation(NED).Methods From September 2007 to October 2014,the clinicopathological features of 70 gastric cardia cancer patients with NED and 76 cases without NED confirmed by surgical pathology specimens and immunohistochemistry (Syn and CgA)in the First Affiliated Hospital of Shantou University Medical College were ret-rospectively analyzed and compared.Results The positive expression rates of synaptophysin(Syn)and chromogranin A(CgA)were 43.2% and 22.6%,respectively.Tumor differentiation was significantly related with NED (χ2 =4.989,P =0.026).Tumors with NED were larger and had deeper invasion,but they were not statistically significant. Conclusion Immunohistochemistry is important to the diagnosis of NED.Gastric cardia cancer with NED has poorer differentiation.
ABSTRACT
Objective To investigate the application of serum NT-PROBNP and cTn level detection in senior acute coronary syndrome(ACS) patients during PCI perioperative.Methods 67 ACS patients who need PCI treatment in the Second People’s Hospital of Liaocheng from April 2013 to April 2014 were selected and their perioperative serum NT-PROBNP and cTn levels were detected.At the same time,30 healthy senior people were chosed as control and their serum NT-PROBNP and cTn levels were also detected.Perioperative serum NT-PROBNP and cTn levels between ACS patients and heathy people were compared,the relationship between serum NT-PROBNP,cTn level and cardiac function of ACS patients were analyzed,and the ROC curve was used to analyze the predictive value of serum NT-PROBNP and cTn joint detection on cardiac function in ACS patients. Results Serum cTnT,cTnI and NT-PROBNP levels of ACS patients were higher than that of healthy senior people (P<0.05 ).Serum cTnT,cTnI and NT-PROBNP levels of ACS patients in postoperative 4h,12h and 24h were higher than that of preoperative,and serum cTnT,cTnI and NT-PROBNP levels in postoperative 72 were lowered,and the differences were statistically significant(P<0.05 ).Pearson correlation analysis results showed that serum cTnT, cTnI and NT-PROBNP levels and heart function of senior ACS patients were negatively correlated (rcTnT=-0.706,rcTnI =-0.841,rNT-PROBNP =-0.822, P<0.05).Area under the ROC curve was 0.678 to 0.945,which belongs to 0.6 -0.9,serum NT-PROBNP and cTn joint detection could well predict the heart function of senior ACS patients.Conclusion Serum cTnT,cTnI and NT-PROBNP levels and heart function of senior ACS patients are negatively correlated.Serum NT-PROBNP and cTn joint detection can be used as predictor of cardiac function of senior ACS patients treated with PCI.
