Purpose To investigate the value of 3.0T MR T1ρquantitative analysis in early detection of disc degeneration. Materials and Methods Conventional T2WI and T1ρwere collected in 35 healthy volunteers (male 16, female 19) on 3.0T MRI, and the classification of disc nucleus was performed by Pfirrmann classification. T1ρvalue of nucleus pulposus was measured and analyzed for the relationship among Pfirrmann classification, segmental and gender. Results There was a significant negative correlation between T1ρvalue and Pfirrmann grade (r=-0.542, P<0.001). T1ρvalue in L5/S1 segment (94.80±26.60) ms was significantly lower than that in L2/L3 (117.18±25.64) ms and L3/L4 (115.52±28.53) ms (P<0.01), and there was no significant difference among other segments (P>0.05);there was no gender differences among the T1ρvalue of each segment (t=0.006, 0.042, 0.797, 1.022, 0.038, P>0.05). Conclusion T1ρ value is closely related to the degree of disc degeneration, and T1ρimaging can be used as an objective, sensitive and effective tool for early detection of disc degeneration.

Quantitative proteomics is a novel subject of proteomics research. There are several new techniques employed for the protein quantitative study. Isobaric tags for relative and absolute quantitation (iTRAQ) technology for protein quantitation using mass spectrometry is a recent powerful means of determining relative and absolute protein levels in up to four samples simultaneously. The iTRAQ reagent produced high quality, reproducible result in enriched complexes, organelles, and whole cell lysates. The status of the recent promising techniques and their possible future evolution were reviewed.

Objective: To investigate the prevalence and influencing factors of dyslipidemia among residents in Chengdu City, so as to provide insights into improving the prevention and control of dyslipidemia. Methods: Based on the baseline survey of the Natural Population Cohort Study in Southwest China, residents aged 30 to 79 years was selected from 34 towns (communities) in 5 counties (districts) of Chengdu City using the multi-stage stratified cluster random sampling method in 2018. Demographic information and lifestyle behaviors were collected through questionnaires. Blood pressure, fasting blood glucose, serum uric acid, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were collected through physical examination and laboratory tests. A multivariable logistic regression model was used to identify the factors affecting dyslipidamia.

The mean flare val- ues in the age groups of 50 years or over were significantly higher than that in the age group of 40-49 years (P

AIMTo survey the uptake behavior and subcellular distribution of antisense oligodeoxynucleotide polymethacrylate submicroparticles (AS-ODN-SMP) and infer its mechanism in MGC cell lines.

METHODSMGC cells were incubated at certain concentration of AS-ODN-SMP or AS-ODN for 8 h at 4 degrees C or 37 degrees C. Then the fluorescence oligodeoxynucleotide- labeled cells were counted by flow cytometer and the intracellular fluorescence intensity was determined after incubated with chloroquine for 2 h.

RESULTSCellular uptake of oligodeoxynucleotides was significantly increased following application of AS-ODN-SMP and total intracellular fluorescence intensity was enhanced by 683 folds with the vehicle concentration of 20 microg x mL(-1). AS-ODN-SMP entranced to cells profoundly with temperature-dependent manner. Rare cells took on fluorescence when incubated at 4 degrees C, while 37 degrees C they were significantly increased. But the intracellular fluorescence intensity appeared same level in present or absent of chloroquine.

CONCLUSIONWith the help of polyacrylate submicroparticles, oligonucleotides efficiently entranced the cells via endocytosis and could successfully escape the degradation in lysosome.
