Cone-beam computed tomography (CBCT)-guided radiotherapy has been widely used in radiotherapy, but it still has many limitations.Using magnetic resonance imaging (MRI) instead of CBCT for imaging-guided radiotherapy can not only make use of the advantages of MRI, but it also allows for online and real-time tracking of tumor motion and biological changes.This technique truly realizes the real-time MRI-guided adaptive radiotherapy (ART) in anatomy and biology, and sets another milestone in the advancement of radiotherapy.This review summarizes the technical advantages of MRI-guided radiotherapy, the basic structure and type of MR-Linac, and the technical difficulties and solutions of MRIgART.

Atherosclerosis is the main cause of coronary heart disease, Now it is thought that atherosclerosis is a chronic inflammatory disease.The ratio of Monocytes to high-density lipoprotein (MHR) is a new inflammatory marker of coronary atherosclerosis, which is measured simply and cheaply.MHR is associated with short-term and long-term incidence of cardiovascular events and morbidity of Coronary heart disease, which can be used as predictor of coronary heart disease prognosis.

Objective To evaluated the result of modified Mitchell operation for treatment of hallux valgus. Methods From March 1998 to October 2001, 39 feet of 20 patients were treated with modified Mitchell procedure. Before operation, HVA averaged 29.5? and IMA averaged 12.5? were measured on standing AP radiographs. The lateral displacement of the capital fragment was depended on the amount of IMA and the capital fragment shifted plantarly 2-3 mm. Fixation was achieved with an absorbable screw. The lateral spike on the distal fragment was not preserved in this operation. Results After follow-up of 11-38 months, patients rated as excellent or good in 97.4%. The average postoperative HVA was 14.5? and IMA was 8.5?, the average HAV correction was 15? and 4? for the IMA. Conclusion The modified Mitchell procedure provides satisfactory deformity correction. The transverse arch of metatarsals is reconstructed since distal part of the first metatarsal is shifted plantarly in this operation.
