AIM: To investigate the regulatory effects of nuclear factor-κB ( NF-κB) and activator protein-1 (AP-1) on the expression of ectopic trypsin and proinflammatory cytokines in influenza A virus (IAV)-induced myocardi-tis.METHODS:Male BALB/c mice of 8 weeks old ( n=40) were randomly divided into 4 groups:normal control group ( NC) , infection control group ( IC) , NF-κB inhibitor group ( NI) and AP-1 inhibitor group ( AI) .The mice in NC group and IC group were instilled intranasally with 15μL saline and 40 plaque forming units ( PFU) IAV, respectively.The mice in NI group and AI group were infected intranasally with 40 PFU IAV and injected intraperitoneally with 10 mg/kg NF-κB inhibitor pyrrolidine dithiocarbamate ( PDTC) or 2.5 mg/kg AP-1 inhibitor nordihydroguaiaretic acid ( NDGA) once daily. The mice were euthanized at day 9 after instillation, and the hearts were removed for pathological and biochemical analysis. RESULTS:IAV infection induced significant up-regulation of ectopic trypsin, and proinflammatory cytokines interleukin 6 (IL-6), IL-1βand tumor necrosis factor-α(TNF-α) in the myocardium, and triggered acute myocarditis.PDTC signifi-cantly inhibited NF-κB activation and up-regulation of ectopic trypsin and proinflammatory cytokines, and effectively sup-pressed IAV replication and myocardial inflammatory response (P<0.01).NDGA effectively inhibited AP-1 activity (P<0.01) and mildly suppressed up-regulation of proinflammatory cytokines ( P<0.05) , but had no effects on the expression of ectopic trypsin, IAV replication and the extent of myocarditis ( P>0.05) .CONCLUSION:IAV infection induces up-regulation of ectopic trypsin and proinflammatory cytokines in myocardium predominantly by the activation of NF-κB.AP-1 signaling pathway might be only partially involved in the regulation of proinflammatory cytokines.

Objective To evaluate the rationale of lowering the cutoff value of impaired fasting glucose(IFG)by studying the extent and severity of angiographic coronary artery disease(CAD)and the cardiovascular risk factors in subjects with different fasting plasma glucose(FPG)levels. Methods A total of 911 consecutive patients who had undergone coronary angiography were selected according to inclusion criteria. The subjects were studied in view of the extent and severity of angiographic CAD and the cardiovascular risk factors with different FPG levels. Results (1) Compared with the group of FPG<5.6mmol/L, the numbers of diseased vessels in the group with FPG 5.6-6.0mmol/L were significantly increased(P<0.05)after adjustment of age, sex and other influencing factors; the group with FPG 6.1-6.9mmol/L had both raised number of diseased vessels and the CAD Gensini cumulative index(P<0.01). (2) The prevalences of overweight, hypertension, hypertriglyceridemia, metabolic syndrome were progressively increasing with graded FPG levels. The prevalence of hypertriglyceridemia was significantly increased with FPG level at 5.0-5.6mmol/L(P<0.05),and the prevalences of metabolic syndrome and other components were significantly elevated with FPG level at 5.6-6.0mmol/L(P<0.05). Conclusion (1) The extent and severity of angiographic CAD were increased with increased FPG even in prediabetic period. The risk of angiographic CAD became increased significantly with FPG at 5.6-6.0mmol/L level. (2) The cardiovascular disease(CVD)risk was also increased with increasing FPG even in prediabetic period. The phenomenon of clustering of CVD risk factors was found at FPG 5.6mmol/L.
