Research progress of cardiac rehabilitation training for patients with left ventricular assist device implantation / 中华胸心血管外科杂志

Left ventricular assist device(LVAD) can improve the survival rate and quality of life of patients with end-stage heart failure, but the quality of life of patients after LVAD implantation is still lower than that of heart transplantation. The reasons for the influence of LVAD implantation on patients' quality of life include discomfort symptoms, surgical complications and high re-hospitalization rate, limitation of physical activity level and negative psychological emotions after device implantation. Cardiac rehabilitation training can improve the quality of life of LVAD patients by improving their psychological state, enhancing their exercise ability and reducing the risk of re-hospitalization. The exercise prescription of LVAD implant patients can include aerobic endurance training, walking training, light to moderate resistance training, gymnastics training, etc. The exercise training intensity should be controlled at the first ventilation threshold(anaerobic threshold), 50% peak oxygen consumption or 12-14 points of Borg scale. In addition, the safety of cardiac rehabilitation training for LVAD patients has been fully demonstrated.

Prevalence study of tumor radiotherapy in the Xinjiang Uygur Autonomous Region / 中国医师杂志

Objective To investigate the development status of tumor radiotherapy in the Xinjiang Uygur Autonomous Region.Methods A questionnaire survey we used last time was conducted by letter,Email,telephone or fax to investigate all the medical institutions in the Xinjiang Uygur Autonomous Region for researching the current status of radiotherapy academic settings,human resources,allocation of radiotherapy facilities and standardization of medical practices.Results Up to the end of January 2015,there were 30 medical electron linear accelerators,21 simulated locators,10 breach-loading brachytherapy machines,31 treatment planning systems and 5γ or X knives in Xinjiang.Radiotherapy was carried out in 20 medical institutions,including 14 three-dimensional conformal radiotherapy and 9 intensity modulated radiation therapy,8 breach-loading brachytherapy,3 stereotactic radiotherapy,and 2 volumetric modulated arc therapy.There were 280 radiation personnel (except nurses),including 159 radiation oncologists,40 radiotherapy physicists and 81 radiotherapy technologists.There were 1167 hospital beds and 855 cancer patients received radiotherapy on average every day.Conclusions Although radiation personnel has increased,radiotherapy facilities have been improved,hospital beds and patients received radiotherapy also have become more,the improvements are needed for cause of imbalance in precise radiation therapy development.
