RÉSUMÉ

ObjectiveTo explore the mechanism of Jiawei Wendantang in preventing and treating diabetic atherosclerosis by observing the effect of this prescription on the nuclear factor-κB / NOD-like receptor protein 3(NF-κB/NLRP3) pathway and related inflammatory cytokines in rat model of diabetic atherosclerosis. MethodFifty-four SPF-grade rats were randomized into blank, model, atorvastatin (0.9 mg·kg-1·d-1), and high-, medium-, low-dose (18.2, 9.1, 4.55 g·kg-1·d-1, respectively) Jiawei Wendantang groups. The rats in other groups except the blank group were modeled for diabetic atherosclerosis by intraperitoneal injection of streptozotocin and feeding with a high-sugar high-fat diet, and those in the blank group were injected with an equal dose of citric acid buffer and fed with a regular diet. The drug administration lasted for 4 weeks, and the blood glucose level in the tail vein was measured every 6 days. After the last administration, the rats were anesthetized for sample collection. Enzyme-linked immunosorbent assay was employed to measure the serum levels of interleukin-18 (IL-18), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and intercellular adhesion molecule-1 (ICAM-1). Western blot was employed to determine the relative protein levels of NF-κB p65, NLRP3, and ICAM-1 in the abdominal aorta. Real-time quantitative polymerase chain reaction was employed to determine the mRNA levels of NLRP3 and interleukin-1β (IL-1β) in the abdominal aorta. The pathological changes in the thoracic aorta were observed by hematoxylin-eosin staining. ResultCompared with the blank group, the model group showed elevated levels of IL-18, CRP, TNF-α, and ICAM-1 in the serum and blood glucose (P<0.05, P<0.01), up-regulated protein levels of NF-κB p65, NLRP3, and ICAM-1 (P<0.01), and up-regulated mRNA levels of NLRP3 and IL-1β (P<0.05). Compared with model group, Jiawei Wendantang lowered the levels of IL-18, CRP, TNF-α, ICAM-1 and blood glucose (P<0.05, P<0.01), down-regulated the protein levels of NF-κB p65, NLRP3, and ICAM-1 (P<0.01), and down-regulated the mRNA levels of NLRP3 and IL-1β (P<0.05, P<0.01). Moreover, Jiawei Wendantang alleviated the pathological injuries in the thoracic aorta. ConclusionJiawei Wendantang may modulate the NF-κB/NLRP3 signaling pathway to reduce the release and adhesion of inflammatory cytokines and regulate the blood glucose level to treat diabetic atherosclerosis.

Prompt defibrillation is believed pivotal to terminate lethal shock-able arrest rhythms. In this study, we were to identify those pre-hospital epidemiological factors which were associated with likelihood of shock-able rhythms first recorded when out-of-hospital cardiac arrest occurred.@*Methods@#A multicenter, secondary, retrospective and observational analysis was performed on all adult non-traumatic OHCA in the Resuscitation Outcome Consortium (ROC) PRIMED study from June 2007 through November 2009. Of a total of 17 177 OHCA cases in PRIMED study, 13 421 of them were enrolled in this study when those OHCA patients with DNR order, or initial rhythms unknown, or arrest caused by obvious cause were excluded. We reported their demographics and episode characteristics for all enrolled cases. Multivariable logistic regression was employed to identify factors which were associated with likelihood of VF/VT recorded as shock-able initial rhythms.@*Results@#Among 13 421 adult non-traumatic OHCA cases with initial rhythms recorded, 3 527 (26.3%) of them had shock-able rhythms, while 9 894 (73.7%) patients were in non-shock-able rhythms. Of the OHCA with shock-able arrest rhythms, 1 850(52.5%) obtained return of spontaneous circulation (ROSC) in the field, while 912 (25.9%) survived to hospital discharge. On the other hand, 2489(25.2%) of the OHCA with non-shock-able arrest rhythms obtained ROSC in the field, while 325 (3.3%) of them survived to hospital discharge. Multivariable regression analysis revealed those factors which indicated likelihood of shock-able rhythms recorded were: age(OR: 0.991,95%CI 0.988-0.993), male gender (OR1.887,95%CI1.718-2.073), pre-hospital Emergency Medical System(EMS) response time(OR0.950,95%CI 0.931-0.970), cardiac arrest witnessed by EMS providers(OR1.709,95%CI 1.423-2.054) or bystander(OR3.199,95%CI 2.921-3.504) and those with bystanders CPR (OR1.357,95%CI 1.239-1.487),public place of cardiac arrest (OR2.705,95%CI 2.437-3.003).@*Conclusions@#Some demographics and pre-hospital characteristics were proved associated with likelihood of shock-able arrest rhythms first recorded in OHCA victims, which might help develop corresponding strategies to deliver prompt shock on initially shock-able patients and improve their outcomes.

RÉSUMÉ

Human height, a complex trait with over 80% heritability, is determined by genetic and environment factors. Currently, a certain amount of specific variants about human height have been found, especially with the widely used of genome-wide association studies (GWAS) in genetics research, making it a great progress for the discovering of height associated genes. However, single nucleotide polymorphisms (SNPs) found by GWAS can only explain a minority of the heritable. This article reviews the progress of GWAS about height associated genes and missing heritability domestic and overseas.
