Acupuncture has been widely used in the treatment of Premature Ovarian Insufficiency(POI), but the selection of acupoints is indeterminate and lacks biological basis.In recent years,some studies suggested the "acupoint sensitization",that is,changes such as pain sensitivity and heat sensitivity appear on the acupoints under disease state.The biological characteristics of acupoints can reflect the state of local tissue and might be a potential factor for guiding acupoint selection. This study aims to compare the temperature and pain threshold of acupoints between POI patients and the healthy population.At the meantime,clinical diagnosis of POI is based on clinical symptoms and Follicle Stimulating Hormone (FSH).However,FSH fluctuates so much that prediction accuracy is not high and clinical application is limited.Therefore, given the lack of proper diagnostic accuracy in POI and the concept of "acupoint sensitization",it is necessary to summarize the changes of biological characteristics of related acupoints under physiological and pathological conditions as an auxiliary means to improve the diagnostic rate of POI.
The study is a case-control study protocol involving 150 POI patients from three clinical centers and 150 healthy persons in China.The duration of the study is one year, and all patients and healthy people will receive at least 3 infrared thermal imaging examinations of acupoints and pain threshold examinations.The primary outcome is to investigate the difference in the skin temperature and pain threshold of acupoints between POI and healthy persons.In the meanwhile,we will collect FSH, serum estradiol (E2) and some relevant scales,including modified Kupperman Index,Zung's Self-Rating Anxiety Scale(SAS),Zung's Self-Rating Depression Scale(SDS),Traditional Chinese medicine(TCM) constitution scale as second outcomes.

| all patients and healthy people will receive at least 3 infrared thermal imaging examinations of acupoints and pain threshold examinations of acupoints. | Device | Infrared thermal imaging detection scheme of acupoints:Detection equipment NEC R550 infrared thermal imager.Records the corresponding acupoints coordinates,and starts to collect the infrared thermal image.and 6 images will be taken continuously for each detected part.The infrared thermograms were stored and extract the temperature values of the corresponding coordinates of the acupoints.The average temperature values of the acupoints in the six infrared thermograms were calculated as their temperatures.Pain threshold detection scheme of acupoints:The instrument and equipment use the FDX25 hand-held pain threshold test instrument to explore the acupoints.Place the probe of the pain measuring instrument vertically on the pain measuring acupoint, slowly and steadily press downward at a constant speed, and stop pressing immediately when the subject begins to feel pain. At this point, the reading on the display is the subject's pain threshold. All acupoints shall be measured once in total. |

| Modified Kupperman | The modified Kupperman Index consists of 13 items . In addition to the same 11 items included in the original Index,the modified version adds urogenital symptoms, including urinary infection and sexual complaints. The original 11 items included sweating/hot flushes, palpitation, vertigo, headache, paresthesia, formication, arthralgia, and myalgia (categorized as somatic symptoms), and fatigue, nervousness, and melancholia categorized as psychological symptoms. A scale ranging from 0 to 3 points is used to describe the severity of the complaints. The weighting factors were the same as those used in the original KI, and provide two points for both urogenital symptoms. The total score ranges from 0 to 63, calculated as the sum of all items by the weighting factor. Scores ranging from 0-6, 7-15, 16-30, and >30 were used to rate the degree of severity as none, mild, moderate, and severe, respectively. |

Premature Ovarian Insufficiency refers to the clinical symptoms of ovarian dysfunction in women before the age of 40, mainly manifested as abnormal menstruation,elevated gonadotropin levels and fluctuating decline in estrogen levels.Currently,POI is diagnosed clinically in patients <40 years of age with abnormal menstruation (amenorrhea or oligomenorrhea>4 months) and FSH>25U/L (two consecutive measurements more than 4 weeks apart).However,FSH fluctuates so much that prediction accuracy is not high and clinical application is limited.The global incidence of POI is 1%,and it is about 2.8% in China.In the long run, POI patients face various health risks, such as increased incidence of cardiovascular diseases, bone and joint diseases, genitourinary diseases, psychological diseases,etc.,and may even lead to shortened life expectancy, which seriously endangers women's physical, psychological and social aspects.

| Zung's Self-Rating Anxiety Scale(SAS) | The SAS is used to assess the subjective feelings of patients with anxiety. SAS has good psychometric credentials, and it is suitable for all types of psychiatric disorders in which anxiety symptoms are predominant. There are 20 items on a four-point scale, and higher scores indicate greater anxiety.SAS has good psychometric credentials and can assist in the assessment of patients' anxiety status. | Baseline,6 months after,12 months after. |
| Zung's Self-Rating Depression Scale(SDS) | The SDS can reflect the depressive state and its variability well (Zung, 1965). The scale contains 20 items scored on a 4-point scale. The rough scores were obtained by summing each of the 20 new items, multiplying the rough scores by 1.25, and then taking the integer part as the standard score. A standard score of 50-59 is considered to be a mild depressive mood, a standard score of 60-69 is considered to be moderate depression, and a standard score of more than 70 is considered to be severe depression. Patients respond according to their situation in the past week. | Baseline,6 months after,12 months after. |
| Traditional Chinese medicine(TCM) constitution scale | TCM constitution scale is Prepared by Professor Wang Qi of Beijing University of Chinese Medicine, in order to evaluate peoplr's TCM constitution.Constitution classification is the basis and core content of TCM constitution research, which is to extract the relevant laws from the complex constitution phenomenon and finally build the constitution classification system.There are 9 items and 66 small items in the TCM constitution scale, which are required to be filled in according to the real situation in the last year. The results of the scale include nine constitutions: mild constitution, qi deficiency constitution, qi depression constitution, yin deficiency constitution, yang deficiency constitution, blood stasis constitution, special constitution, phlegm-dampness constitution and damp-heat constitution. | Baseline,6 months after,12 months after. |
| Follicle Stimulating Hormone | Clinical diagnosis of POI is based on clinical symptoms and Follicle Stimulating Hormone (FSH).However,FSH fluctuates so much that prediction accuracy is not high and clinical application is limited | Baseline,6 months after,12 months after. |
