Postoperative delirium (POD) increases the risk of postoperative dementia and mortality. Cognitive decline is common in patients with diabetes mellitus. As an independent risk factor for POD, diabetes significantly increases postoperative dementia and mortality. Our team found that acupuncture can reduce the incidence of POD in elderly patients, increase regional cerebral oxygen saturation (rSO2), and increase cerebral blood flow perfusion in diabetic patients. In this study, a prospective randomized controlled study with placebo acupuncture will be conducted. Diabetic patients undergoing elective surgery will be divided into acupuncture group, placebo acupuncture group and control group. Acupuncture will be used as the intervention method, and the incidence of POD will be the main therapeutic effect evaluation index to explore the efficacy of acupuncture in the prevention and treatment of POD in diabetic patients undergoing surgery.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| acupuncture group | Experimental | In the acupuncture group, acupoints of Baihui, Shenting, Sishencong will be selected for acupuncture stimulation be anesthesia. The needle will be kept for 30 minutes, during which the needle will be performed once every 10 minutes for 10 seconds each time, 4 times in total. The therapist will give the subject verbal cues before and during the needle manipulation. |
|
| placebo acupuncture group | Placebo Comparator | The patients will be treated with consolation needle. Choose treatment of points that near but without going through the acupoints(upper arm deltoid muscle). Use the Park needle (blunt needle, tip obtuse, when acupuncture the feeling is similar to acupuncture needles into the skin, but it retracts instead of piercing the skin) to conduct acupuncture treatment. The retention time and number of needles will be the same as those in the acupuncture group. The therapist will give the subjects verbal cues before and during the acupuncture manipulation, which further reduces the subjects' doubts about the authenticity of acupuncture in the this group. To ensure the implementation of the blinding method, all patients will be treated independently and avoid contacting with each other. |

| control group | No Intervention | The patients will undergoing routine anesthesia without acupuncture treatment. |

| Measure | Description | Time Frame |
|---|---|---|
| Regional Saturation of Oxygenation (rSO2) | The brain oxygen saturation monitoring electrode was attached to the forehead, and the baseline level (T0) was recorded after the reading was stable under the condition of air inhalation. rSO2 readings were recorded after induction (T1), at the beginning of surgery (T2), one hour after the beginning of surgery (T3), at the end of surgery (T4), and after extubation (T5). The maximum and minimum values of rSO2 readings during surgery were recorded, and the area under the rSO2 curve was recorded when the rSO2 reading decreased by 13% from baseline for more than 5 minutes. rSO2 values of each time point, maximum and minimum values during surgery. |
| Measure | Description | Time Frame |

| Height | Record the height (in meters) of the patient | The 1 day before surgery |
| Weight | Record the weight (in kilograms) of the patient | The 1 day before surgery |
