[Heat-sensitive moxibustion assisted in palliative treatment to improve the quality of life in elderly patients with malignant tumor: a randomized controlled trial].

Objective: To observe the effect of heat-sensitive moxibustion on the quality of life in the elderly patients with malignant tumor based on palliative treatment.

Methods: A total of 100 elderly patients with malignant tumor were randomly divided into an observation group (50 cases, 3 cases dropped out) and a control group (50 cases, 4 cases dropped out). The conventional palliative treatment was performed in the control group.

Single crystalline magnetite nanotubes.

We descried a method to synthesize single crystalline Fe3O4 nanotubes by wet-etching the MgO inner cores of MgO/Fe3O4 core-shell nanowires. Homogeneous Fe3O4 nanotubes with controllable length, diameter, and wall thickness have been obtained. Resistivity of the Fe3O4 nanotubes was estimated to be approximately 4 x 10-2 Omega cm at room temperature.
