Absence of association between SERPINE2 genetic polymorphisms and chronic obstructive pulmonary disease in Han Chinese: a case-control cohort study

Background: Recent studies have proposed that the serine protease inhibitor E2 (SERPINE2) was a novel susceptibility gene for chronic obstructive pulmonary disease (COPD) in Caucasians. However, this issue still remained controversial. Additional evidence

Relationship between COPD and polymorphisms of HOX-1 and mEPH in a Chinese population

Recent studies have proposed that susceptibility to chronic obstructive pulmonary disease (COPD) might be related with the polymorphisms of some genes encoding antioxidant enzymes, such as heme oxygenase-1 (HOX-1) and microsomal epoxide hydrolase (mEPH).

慢性阻塞性肺病中医五脏关系及其病变规律的研究

目的:用数据挖掘的方法分析慢性阻塞性肺病病变过程中中医五脏的传变规律及其相互影响关系。方法:建立慢性阻塞性肺病病例数据库,将数据库中的数据预处理转换,并导出到W eka的格式(.arff),然后利用W eka进行相关的数据挖掘分析。结果:在慢性阻塞性肺病的病变过程中,初起病位在肺,逐步转变为肺脾肾、肺脾心同病,后期肺脾心肝肾五脏俱损,且中焦脾土是其传变的关键。结论:应用数据挖掘的方法分析疾病病变过程中五脏的传变关系及其相互影响关系具有一定的应用前景。

Measurement of respiratory acoustic impedance in children by a modified forced oscillation method

An introduction to a modified forced oscillation method, square-wave excitation technique, including fundamentals and methods, as used in respiratory function examination. On the basis of experimental results and theoretical predictions, we suggest that Respiratory Acoustic Impedance (RAI) measurement by spectral analysis can significantly improve estimation of contribution to RAI from different part of respiratory tract. The outcome is of considerable interest in the study of lung disease, such as COPD and asthma in young children.
