Acute myocardial infarction （AMI）, the most severe .coronary artery disease, is one of the most frequent cardiac emergencies, and early diagnosis and treatment are very important to decrease the subsequent cardiac adverse events such as malignant arrhythmia and sudden cardiac death. But in fact, lots of diseases are similar to AMI in clinical practice, of which the most common are myocarditis, pulmonary embolism in department of cardiology. Here we report a case of AMI-like squamous cell lung cancer with bone metastases.

Objective The alpha 2A-adrenergic receptor gene （ADRA2A） polymorphism in individuals antiplatelet response to sympathetic stimulation. The aim of this study was to investigate ADRA2A variants on platelet reactivity in Chinese patients on dual antiplatelet therapy undergoing percutaneous coronary intervention （PCI）. modifies the the effect of （DAPT） after Methods From March 2011 to March 2013, 1,024 patients were enrolled in this prospective, single-center, observational study in China. Four single nucleotide polymorphisms （SNPs） of ADRA2A gene （rs11195419, rs3750625, rs13306146, and rs553668） and CYP2C19^＊2 were detected by ligase detection reaction （LDR）, and adenosine diphosphate （ADP） inhibition was detected by thromboelastography （TEG）. Results The minor allele frequencies of ADRA2A SNPs were common. Platelet ADP inhibition was significantly different among patients carrying rs11195419 （adjusted P = 0.022） and rs3750625 （adjusted P = 0.016）. The homozygous allele carriers had the lowest ADP inhibition. However, ADP inhibition was not significantly different in rs553668 and rs13306146. At the multivariate analysis, rs11195419 （P = 0.033）, rs3750625 （P = 0.020） and CYP2C19＂2 （P = 0.002） were independent predictors of ADP inhibition. Subgroups analysis based on sex showed rs11195419 （P = 0.003） and rs3750625 （P = 0.002） were significantly associated with ADP inhibition in males, but not in females. Conclusion ADRA2A genetic variations were associated with ADP-induced platelet aggregation during DAPT in Chinese patients undergoing PCI, and the effect was particularly more pronounced in males.

Background Insulin resistance （IR） is present at all stages of chronic kidney disease （CKD） and is associated with CKD progression. Probueol can improve the prognosis of IR in diabetes mellitus （DM） patients. This study aimed to observe the effect of probucol on IR and kidney protection in non-diabetic CKD patients. Methods This was an open-label, non-placebo-controlled, randomized study. A total of 59 patients were randomized to the probucol group （0.5 g, twice daily） or the control group using a 1： 1 treatment ratio. IR was determined using a homeostatic model assessment-IR （HOMA-IR） index. An Excel database was established to analyze foUow-up data at weeks 0, 12, and 24. The primary outcome of interest was changes in the HOMA-IR, and the secondary outcomes of interest were changes in the estimated glomerular filtration rate （eGFR）, body mass index （BMI）, cholesterol, triglycerides, high-density lipoprotein （HDL）, low-density lipoprotein （LDL）, and 24-h urinary protein. Results The HOMA-IR index of the probucol group after 24 weeks was significantly decreased （P 〈 0.001） compared to the value before treatment （average decrease： 1.45; range： -2.90 to -0.43）. The HOMA-IR index in the control group increased （average increase： 0.54; range： -0.38 to 1.87）. For the secondary outcomes of interest, the changes between these two groups also exhibited significant differences in eGFR （P = 0.041）, cholesterol （P = 0.001）, fasting insulin （P 〈 0.001）, and fasting C-peptide （P = 0.001）. Conclusions Compared to angiotensin receptor blockers alone, the combination with probucol ameliorates IR in non-diabetic CKD patients and delays disease progression.

Based on the concept of adiabatic invariant, the perturbation to mei symmetry and Noether adiabatic invariants for Birkhoffian systems are studied. The exact invariants of mei symmetry for the system without perturbation are given. The perturbation to mei symmetry is discussed and the Noether adiabatic invariants induced from the perturbation to mei symmetry of the system are obtained.
