Objective:To study the clinical prognosis and related factors affecting optimal medical therapy (OMT) compliance of patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI).Methods:A prospective study was conducted to select 3 818 patients who were diagnosed with CAD and successfully underwent PCI in TEDA International Cardiovascular Hospital from October 2016 to September 2017. The clinical information and application of OMT during hospitalization and 1 year later were collected for research.The patients were divided into OMT group and non OMT group according to whether they adhered to OMT during follow-up one year after discharge. After comparing the imbalance baseline data of hypertension,diabetes and hyperlipidemia with propensity score,demographic characteristics, coronary revascularization history, CAD, laboratory related laboratory examinations,and the use of OMT drugs were compared between the two groups. Cox regression model was used to analyze the relationship between long-term OMT and clinical prognosis in patients with CAD.Multivariate binary logistic regression was used to analyze the related factors affecting long-term OMT compliance.Results:A total of 3 818 cases of CAD patients were matched by propensity score and 2 596 patients were included in the study. There were 1 609 males and 987 females. The age was (62.51±9.56) years old.One year later,1298 patients (50%) insisted on OMT,including dual antiplatelet therapy(DAPT), statins, β-blockers and ACEI/ARB were 97.0% (2 517/2 596),94.5%(2 454/2 596),69.6% (1 806/2 596) and 64.2% (1 666/2 596), especially angiotensin converting enzyme inhibitors / angiotensin receptor blockers and β Receptor blockers decreased the most.Cox regression analysis showed that after adjusting for other factors, compared with non-adherence to OMT group,OMT after PCI was associated with better prognosis ( HR=0.416,95% CI 0.270-0.641, P<0.001). The prognosis of CAD patients with history of old myocardial infarction ( HR=1.804,95% CI 1.070-3.041, P=0.027),cardiac insufficiency ( HR=2.074,95% CI 1.161-3.702, P=0.014),multivessel coronary disease ( HR=2.211,95% CI 1.228-3.983, P=0.008) and BMI>24 ( HR=1.570,95% CI 1.037-2.377, P=0.033) were related to worse clinical outcomes. Multi-factor binary Logistic regression showed that OMT at hospitalization was a strong influencing factor of long-term adherence to OMT ( OR=41.278,95% CI 29.961-56.871, P<0.001). Patients with higher education,employee medical insurance and with history of PCI tend to persist in OMT. Conclusion:The medication compliance of patients with long-term OMT after PCI is still poor,while the high compliance of OMT is related to the lower incidence of adverse cardiovascular events,including death, nonfatal myocardial infarction and stroke. If there is no obvious contraindication,all patients after PCI should adhere to OMT.

Objective:To analyze the change of differential genes and signaling pathways in high glucose induced BV2 cells, and to explore the mechanism of transgelin-2 (TAGLN2) regulating cellular inflammatory response and metabolic process.Methods:An experimental study. The cultured BV2 cells were divided into mannitol treatment (Man) group, glucose treatment (Glu) group, overexpression control Glu treatment (Con) group, overexpression TAGLN2 Glu treatment group, silence control Glu treatment (shCon Glu) group, and silence TAGLN2 Glu treatment (shTAGLN2 Glu) group. Cells in the Man group were cultured in modified Eagle high glucose medium (DMEM) containing 25 mmol/L mannitol and 25 mmol/L glucose, cells in other groups (Glu group, Con Glu group, TAGLN2 Glu group, shCon Glu group and shTAGLN2 Glu group) were cultured in DMEM medium containing 50 mmol/L glucose. After 24 hours of cells culture, transcriptome sequencing of cells in each group were performed using high-throughput sequencing technology, and significantly differentially expressed genes (DEG) were screened. |log 2 (fold change)|≥1 and P≤0.05 were adopted as criteria to screen for DEG. Gene Ontology (GO) function enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and protein-protein interaction network analysis were performed. Real-time polymerase chain reaction (RT-PCR) was used to detect the relative expression level of DEG mRNA. The data between groups were compared by independent sample t-test. Results:When compared with Man group, a total of 517 differentially expressed genes were screened in Glu group, which including 277 up-regulated genes and 240 down-regulated genes. KEGG pathway enrichment analysis showed that the up-regulated genes were significantly enriched in immune system processes such as nuclear factor (NF)-κB signal pathway, Jak-signal transducers and activators of transcription (STAT) signal pathway, while down-regulated genes were significantly enriched in glycosaminoglycan degradation and glyceride metabolic pathway. Compared with Con Glu group, a total of 480 DEG were screened in TAGLN2 Glu group, among which 147 up-regulated and 333 down-regulated genes were detected. Up-regulated genes were significantly enriched in the metabolic processes of fatty acid, glyceride and pyruvate, while down-regulated genes were significantly enriched in immune system processes such as NF-κB signal pathway, Jak-STAT signal pathway and tumor necrosis factor (TNF) signal pathway. Compared with shCon Glu group, a total of 582 DEG were screened in shTAGLN2 Glu group, among which 423 up-regulated and 159 down-regulated genes were detected. Up-regulated DEG were significantly enriched in immune system processes such as TNF signal pathway and chemokine signal pathway, while down-regulated DEG were significantly enriched in pattern recognition receptor signal pathway. RT-PCR results showed that the relative expression levels of DEG mRNA Card11 ( t=13.530), Icos ( t=3.482), Chst3 ( t=6.949), Kynu ( t=5.399), interleukin (IL)-1β ( t=2.960), TNF-α ( t=5.800), IL-6 ( t=3.130), interferon-γ ( t=7.690) and IL-17 ( t=6.530) in the TAGLN2 Glu treatment group were decreased significantly compared with Con Glu group, and the difference was statistically significant. Conclusion:TAGLN2 can inhibit glucose induced microglia inflammation by NF-κB and Jak-STAT signaling pathways, Card11, Icos, Chst3 and Kynu play an important role in the anti-inflammatory process of TAGLN2.

Objective:
To investigate the current status and real performance of the detection of RUNX1-RUNX1T1 fusion transcript levels and WT1 transcript levels in China through interlaboratory comparison.
Methods:
Peking University People’s Hospital (PKUPH) prepared the samples for comparison. That is, the fresh RUNX1-RUNX1T1 positive (+) bone morrow nucleated cells were serially diluted with RUNX1-RUNX1T1 negative (-) nucleated cells from different patients. Totally 23 sets with 14 different samples per set were prepared. TRIzol reagent was added in each tube and thoroughly mixed with cells for homogenization. Each laboratory simultaneously tested RUNX1-RUNX1T1 and WT1 transcript levels of one set of samples by real-time quantitative PCR method. All transcript levels were reported as the percentage of RUNX1-RUNX1T1 or WT1 transcript copies/ABL copies. Spearman correlation coefficient between the reported transcript levels of each participated laboratory and those of PKUPH was calculated.
Results:
①RUNX1-RUNX1T1 comparison: 9 samples were (+) and 5 were (-) , the false negative and positive rates of the 20 participated laboratories were 0 (0/180) and 5% (5/100) , respectively. The reported transcript levels of all 9 positive samples were different among laboratories. The median reported transcript levels of 9 positive samples were from 0.060% to 176.7%, which covered 3.5-log. The ratios of each sample’s highest to the lowest reported transcript levels were from 5.5 to 12.3 (one result which obviously deviated from other laboratories’ results was not included) , 85% (17/20) of the laboratories had correlation coefficient ≥0.98. ②WT1 comparison: The median reported transcript levels of all 14 samples were from 0.17% to 67.6%, which covered 2.6-log. The ratios of each sample’s highest to the lowest reported transcript levels were from 5.3-13.7, 62% (13/21) of the laboratories had correlation coefficient ≥0.98. ③ The relative relationship of the reported RUNX1-RUNX1T1 transcript levels between the participants and PKUPH was not always consistent with that of WT1 transcript levels. Both RUNX1-RUNX1T1 and WT1 transcript levels from 2 and 7 laboratories were individually lower than and higher than those of PKUPH, whereas for the rest 11 laboratories, one transcript level was higher than and the other was lower than that of PKUPH.
Conclusion
The reported RUNX1-RUNX1T1 and WT1 transcript levels were different among laboratories for the same sample. Most of the participated laboratories reported highly consistent result with that of PKUPH. The relationship between laboratories of the different transcript levels may not be the same.
