Brief Summary

Repetitive transcranial magnetic stimulation (rTMS) is a new neuroelectrophysiological technique developed in recent years. rTMS can affect local and distant cortical function, promote regional reconstruction of cortical function, and has clear curative effect on a variety of neuropsychiatric diseases. Previous study found that rTMS can improve postoperative cognitive function, and there may be a dual biological mechanism. Brain network abnormalities may be the direct cause of postoperative cognitive dysfunction, and neuroinflammation is one of the key molecular mechanisms behind postoperative cognitive dysfunction . rTMS may play a role in the regulation of brain network and inflammatory molecules, and thus play a role in the prevention and treatment of postoperative cognitive dysfunction (POCD).

Study Arms (2)

Intervention group

EXPERIMENTAL

Subjects underwent repetitive transcranial magnetic stimulation for five consecutive days from day 2 to day 6 after surgery. The stimulation target area was the posterior cingulate gyrus, and the neuronavigation system was used to accurately locate the stimulation target in this project. Continuous theta short rapid pulse mode (cTBS) was used. CTBS mode consisted of a slave stimulus delivered every 0.2 seconds (5Hz), and each slave stimulus consisted of three bursts of 50Hz. A single stimulus lasts about 40 seconds and totals 600 pulses. Stimulation sessions are from 8 to 10 a.m. daily.

Device: repetitive transcranial magnetic stimulation

Control group

SHAM COMPARATOR

Subjects underwent repetitive transcranial magnetic stimulation for five consecutive days from day 2 to day 6 after surgery,but the machine does not turn on.

Device: pseudo repetitive transcranial magnetic stimulation

Interventions

The neural navigation system was used to accurately locate the stimulus target.Continuous theta short rapid pulse mode was used. CTBS mode consisted of a slave stimulus delivered every 0.2 seconds (5Hz), and each slave stimulus consisted of three bursts of 50Hz. A single stimulus lasts about 40 seconds and totals 600 pulses.

Intervention group

Participant in control group receive pseudo repetitive transcranial magnetic stimulation
