Review[Application of the inspiratory impedance threshold device and its research progress].
The inspiratory impedance threshold device (ITD) was put forward by Lurie in 1995, and was assigned as a class II a recommendation by the International Liaison Committee on Resuscitation (ILCOR) resuscitation guidelines in 2005. The ITD is used to augment negative intrathoracic pressure during recoil of the chest so as to enhance venous return and cardiac output, and to decrease intracranial pressure. In the recent years many researches on the ITD have been1 carried out, but all the researches can not take out a clear evidence to support or refute the use of the ITD. This paper introduces the structure and working principle of the ITD in detail, the research results and the debates about the use of the ITD for the past years.

Review[Progress of studies for reduction of ghost artifact in magnetic resonance imaging].
The popularity of magnetic resonance imaging over other imaging disciplines depends predominantly on its high spatial resolution, soft tissue contrast, no hard fake trace and no radiation injury. However, the ghost artifacts produced during a magnetic resonance imaging would degrade the image badly and affect the precise orientation to focus. ⋯ A lot of researches indicated that how to reduce the ghost effectively is still a challenging task. Researchers should persist in seeking for new method to solve the difficult problem.

Epigenetic modifications, including DNA methylation, histone modifications, RNA epigenetics and nucleosome remodeling, are important for gene transcription, but such modifications do not change the coding sequence of the gene. Although these events are heritable, they are potentially reversible, thus opening up opportunities for the therapy of cancer. ⋯ In this review, we summarized the research progress of epigenetic gene regulation and the proteins which could read epigenetic codes. And the relationship between epigenetics and cancer was discussed comprehensively.

Monitoring the depth of anesthesia (DOA) is essential for improving the quality of anesthesia and ensuring the patient's safety and rehabilitation. Monitoring DOA can increase the quality of anesthesia and the safety of operation, thus decreasing the complications caused by anesthesia. With the development of electronic and information technology, the researches for detecting DOA have made great progress. In this paper, the techniques for monitoring DOA are reviewed.
