Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The number of people enrolled in the Court is 170.
Between 20 and 90 years old, meet the following conditions, suitable for participation in this test:
1. Healthy subjects of different ages (20 persons): to study the optical imaging of the skin and nerve endings: the control of healthy subjects and peripheral neuropathy patients skin observed by the optical images of the shoots.
2. Abandoned extra digit specimen of polydactyly(10 persons): to study the optical imaging of the normal skin and nerve endings in extra digit : collect abandoned digit specimen after surgical removal in polydactyly.
3. has been diagnosed with peripheral neuropathy (90 persons):to study the diagnosis of peripheral neuropathy of the skin nerve endings of the optical image observation and quantitative sensory nerve examination
4. clinically must be diagnosed by the skin slices of diabetic neuropathy patients have been removed after the completion of clinical diagnosis of the specimen,And then the skin slices of the nerve endings of the optical image observation (20 persons):study the technical observation of diabetic patients with skin sections of the nerve endings of the optical image observation: the clinical must be skin slices for the diagnosis of diabetic neuropathy, patients has been taken out after the completion of clinical diagnosis, and then the skin slices of the nerve endings of the light learning image observation.
5. because of chemotherapy during chemotherapy, is expected to have peripheral neuropathy: before the occurrence of peripheral neuropathy , Peripheral nerve lesions were cured after subcutaneous nerve optical observation (30 persons):for different periods of peripheral neuropathy subcutaneous nerve optical observation: in the peripheral neuropathy occurred before the occurrence of peripheral neuropathic symptoms, peripheral neuropathy after cure for subcutaneous nerve optical observation.
This test can not be attended if:
Those who suffer from systemic infection or have been infected with the site by the physician assessment is not suitable for examination.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Healthy subjects
Healthy subjects of different ages (20 persons), Interventions: harmonic generation microscopy
harmonic generation (HGM) microscopic methods.
a frequency-dependent optical microscopy system with a near-infrared light source with a wavelength of 1230 nm was used to detect the diseased site and normal skin.Use erbium-Jacob (Er-YAG) laser exfoliation. the participants need to lie down, wear goggles. The lens sucker device to help fix the skin examination site. Based on the experience of the past 118 subjects, the participants did not discomfort. The total time of the laser irradiation on the same skin is no more than 30 minutes, the maximum laser power is no more than 0.15 watts, irradiation in the skin of the total energy of the laser does not exceed 270 joules. After the experiment, the investigators immediately check the skin for the participants
peripheral neuropathy
the participant have symptoms and diagnosed with peripheral neuropathy (90 persons), Interventions:harmonic generation microscopy
harmonic generation (HGM) microscopic methods.
