[ASPIRE guidelines and their enlightenment on application of sham acupuncture in clinical researches]

Reasonable and standard application of sham acupuncture control is the key to determine the quality of acupuncture clinical trials, and is also a difficult problem faced by acupuncture clinical research. The UK National Institute for Health Research and the Medical Research Council jointly published the Applying Surgical Placebo in Randomised Evaluation (ASPIRE) guidelines on the application of placebo surgical operation in randomized evaluation, which includes 4 parts: rationale and ethics, design, conduct, and interpretation and translation, providing comprehensive guidance for the application of placebo controls in surgical trials. As an operational intervention, acupuncture is similar to surgery, so, ASPIRE guidelines can also provide certain guidance for the application of sham acupuncture. In the present paper, we introduce the ASPIRE guidelines, and put forward its enlightenment and reference to the application of sham acupuncture control in combination with retrospecting the current situations of sham acupuncture research. We hold that future studies should strengthen the consideration of the rationality and ethics of sham acupuncture, standardize the design of sham acupuncture control, and convey the information related to sham acupuncture to patients with appropriate descriptions.
