Decitabine is a methylation inhibitor,which is different from traditional chemotherapy drugs,with new and unique mechanism of action,and represent a new therapeutic concept.Methylation present in almost all cells,by inhibiting DNA methyltransferase,causing hypomethylation of DNA and cell differentiation or apoptosis to anti-tumor effect.In this paper,methylation inhibitor decitabine treatment of hematological malignancies in the application are reviewed.

Many interventional procedures have been practiced in the treatment of cervical spine diseases for recent years. There are percutaneous biopsy, periradicular therapy for cervical never pain, percutaneous vertebroplasty and many kinds of intervertebral disc decompression. However, because of the manipulation difficulties and high risks of these procedures the popularization of interventional techniques in treating cervical spine disorders has actually been beset with difficulties. The main risks caused by interventional operation are puncture injuries and side-effect of therapeutic design. Therefore, how to reduce the procedure’s risk is a great challenge to interventional radiologists as well as an urgent research task.

Interventional radiology has lot of advantages in dealing with various emergencies. The technique is minimally-invasive,highly-effective and immediately-efficient,moreover,it integrates the diagnosis with the therapy perfectly. Besides,the interventional techniques applied in emergency medicine include not only the vascular interventions,such as embolization,embolectomy,etc,but also the nonvascular interventions,such as tracheal stent implantation,percutaneous vertebroplasty and so forth. However,importance has not been attached to the clinical use of interventional therapy in emergency medicine so far. It is imperative for us to promote the acceptance of interventional therapy in emergency medicine as well as to popularize the technique in clinical practice.

Stricture and insufficiency of eustachian tube in 43 cases were treated by floating duct for dilation of eustachian tube under fiber endoscopy. Clinical observation lasbed 2-10 months. 23 cases were significantly effective, 13 cases effective. No intraoperative complications.

CYP3A plays central roles in the oxidative and reductive metabolism of a variety of enogenous as well as exogenous compounds, it is very important to study about regulation of CYP3A geneexpression. This article reviews the recent development of molecular mechanism of regulation of CYP3A gene expression and CYP3A mutation. The relationships between CYP3A mutant and some diseases are also introduced.
