对不典型心肌梗死误诊的临床分析

Objective:to analyse the reason of misdiagnosis of atypical myocardial infarction.Methods: To analyze 12 cases by combining with typical cases. Results:12 cases were misdiagnosed as stomach problem,bronchial asthma,micturition syncope,cor pulmonale right heart failure,diabetic coma,acute cholecystitis,intercostals neuralgia,arrhythmia,etc.Conclusion: The misdiagnosis is mainly due to the clinician’s less experience, insufficient attention to patients, stop-gap measures, narrow mind of clinical diagnosis, lack of understanding of atypical myocardial infarction, subjective diagnoses, lack of understanding myocardial infarction in the elderly, variability,lack of routine dynamic monitoring examination of electrocardiogram and serum myocardial enzyme. 目的 分析不典型心肌梗死的误诊原因。方法 结合典型病例，对12例患者进行分析。结果 12例患者分别误诊为：胃病、支气管哮喘、排尿性晕厥、肺心病右心衰、糖尿病昏迷、急性胆囊炎、肋间神经痛、心律失常等。结论 误诊原因主要是临床医师经验少，对患者不够重视，以症为病，临床诊断思路狭隘，缺乏对不典型心肌梗死的认识，主观看病诊断，缺少对老年心肌梗死多变性的认识，对常规心电图、血清心肌酶检查缺乏动态监测。   

New type of hydrogenlike charm-pion or charm-kaon matter

Borrowing the structures of the hydrogen atom, molecular ion, and diatomic molecule, we predict the nature of a new type of hydrogenlike charm-pion or charm-kaon matter that could be obtained by replacing the proton and electron in hydrogen matter with a charmed meson and a pion or a kaon, respectively. We find that the spectra of the atom, molecular ion, and diatomic molecule can be obtained simultaneously with the Coulomb potential for the hydrogen, the charm-pion, and the charm-kaon systems. The predicted charm-pion matter also allows us to explore the mass shift mediated by the strong interaction. For the charm-pion and charm-kaon systems, the strong interactions could lead to binding energy shifts. Our calculations suggests that the binding energy shifts in charm-pion systems are in the order of several to tens of eV. For the charm-kaon systems, the results are in the order of tens to hundreds of eV. Exploring hydrogenlike charm-pion matter must lead to new demands for high-precision experiments.Comment: 5 pages, 4 figures and 1 table. Typos corrected. Accepted by Phys. Rev.

Microwave Assisted Hydrolysis Of Holocellulose Catalyzed With Sulfonated Char Derived From Lignin-Rich Residue

A microwave assisted green process has been developed for production of sugars through liquefying holocellulose catalyzed with sulfonated char derived from the lignin-rich residue produced during pretreatment of lignocellulose. Various reaction parameters including the hydrolysis temperature, hydrolysis time, catalyst content, and the ratio of water to feedstock were evaluated. The maximum sugars yield of 82.6% (based on the dry mass of holocellulose) was obtained under the optimum reaction conditions. The sulfonated char showed superior catalytic performance to that of dilute sulfuric acid in converting holocellulose into sugars under microwave irradiation
