In recent years, commonly used Omics techniques, including genomics, proteomics, metabolomics, have been applied in the studies on the mechanism of acupuncture effect. In the previous study, "Immediate effects of proximal and distal acupoints on the Radial Pressure Pulse-wave in patients with knee osteoarthritis: a randomized controlled trial", significant changes in the spectral-energy of the pulse wave in the proximal-acupoint treatment group and the distal-acupoint treatment group infer pain relief and blood-flow improvement. The scores of the Visual Analog Scale were decreased, and the passive and active range of knee motions were increased. Both of the proximal and distant acupoints could be used for knee osteoarthritis treatment. To advance the previous work by becoming one treatment, this study will explore if there is any Omics difference resulting from the two acupoints, thus examining the mechanism of curative effect of acupuncture. Additionally, Chinese medical emphasizes the relationship between body constitution and diseases and the dynamic change of pulses and meridians during the disease development. These significances are in agreement with Omics features about organism integrity, dynamic, and complexity. The current study will adopt a Chinese medical body constitution survey, the spectral-energy (SE) changes of the pressure wave from the radial artery, and the pulse energy analysis of Ryodoraku to identify the differences in specific genes, protein, and metabolites of various body constitutions, pulses, changes of the pressure wave, aiming to set up the objectification of Chinese medical diagnosis.
Introduction: In recent years, commonly used Omics techniques, including genomics, proteomics, metabolomics, have been applied in the studies on the mechanism of acupuncture effect. In the previous study, "Immediate effects of proximal and distal acupoints on the Radial Pressure Pulse-wave in patients with knee osteoarthritis: a randomized controlled trial", significant changes in the spectral-energy of the pulse wave in the proximal-acupoint treatment group and the distal-acupoint treatment group infer pain relief and blood-flow improvement. The scores of the Visual Analog Scale were decreased, and the passive and active range of knee motions were increased. Both of the proximal and distant acupoints could be used for knee osteoarthritis treatment. To advance the previous work by becoming one treatment, this study will explore if there is any Omics difference resulting from the two acupoints, thus examining the mechanism of curative effect of acupuncture. Additionally, Chinese medical emphasizes the relationship between body constitution and diseases and the dynamic change of pulses and meridians during the disease development. These significances are in agreement with Omics features about organism integrity, dynamic, and complexity. The current study will adopt a Chinese medical body constitution survey, the spectral-energy (SE) changes of the pressure wave from the radial artery, and the pulse energy analysis of Ryodoraku to identify the differences in specific genes, protein, and metabolites of various body constitutions, pulses, changes of the pressure wave, aiming to set up the objectification of Chinese medical diagnosis. Method: The study will recruit 60 participants, which will be recruited when they meet the Clinical Classification Criteria for KOA, that is knee pain and three out of six symptoms can be found in clinical practices, as recommended by the American College of Rheumatology:(a) any gender aged 50 years or above;(b) have less than 30 minutes of morning stiffness; (c) crepitus on active motion; and (d) bony tenderness;(e) bony enlargement; and (f) no palpable warmth. They will be randomly assigned to two groups: the distal-acupoint treatment group (DG) (LI11, HT3 and TE10 and the proximal-acupoint treatment group (PG) (GB34, SP9 and EX-LE2). The study will last for five weeks. Each week has two sessions, as a total of ten sessions. The participants will have blood tests in the following times: before the first acupuncture, after the fifth acupuncture and the tenth acupuncture, three weeks after the end of treatment. The study design is random and single-blind. The participants The primary outcome will come from the assessment: comparing the expressed differences of the genes, proteins, and metabolites of the two acupoints. The secondary outcome will be from the connection among 1) the expressed differences of the specific genes, proteins, 2) the survey of Chinese medical body constitution, 3) the spectral-energy (SE) changes of the pressure wave from the radial artery, and 4) the Ryodoraku pulse energy. Expected outcome: The study will use the principle and techniques of Omics to explore the mechanism of the curative effect caused by acupuncture on different acupoints. It is expected to serve as a bridge to connect between contemporary medical and traditional medical.

the expressed differences of the genes of the two acupuncture groups.
The blood samples will be collected 4 times and analyzed which type of gene by quantitative real time-PCR.
Time frame: through study completion, an average of 1 year
the expressed differences of the proteins of the two acupuncture groups.
The blood samples will be collected 4 times and analyzed which type of proteins by Micro-Western Array
Time frame: through study completion, an average of 1 year
the expressed differences of the metabolites of the two acupuncture groups.
The blood samples will be collected 4 times and analyzed which type of metabolites by LC-MS/MS.
Time frame: through study completion, an average of 1 year
Assessment of Radial Pressure Pulse-wave
Assessment of Radial Pressure Pulse-wave at Cun, Guan \& Chi of both hands before and after the intervention using Pulse Sphygmograph.
Time frame: There are two sessions each week. The participants will be measured twice in each session. The first time is 10 minutes before the acupuncture treatment; the second time is 10 minutes later after the acupuncture treatment
Assessment of meridian energy
Assessment of the energy of twelve meridians before and after the intervention using Ryodoraku.
Time frame: There are two sessions each week. The participants will be measured twice in each session. The first time is 15 minutes before the acupuncture treatment; the second time is 15 minutes later after the acupuncture treatment
Range of knee motion
Range of knee motion will be examined by a goniometer.
Time frame: before the first session (which is in the first week), after the tenth session (which is in the fifth week), and the three weeks later after the end of the treatment (which is in the eighth week)
Visual analog scale (VAS)
The intensity of pain is measure using VAS for pain. It is incorporated into the questionnaire with a scale of 0 (no pain) to 10 (worst pain possible)
Time frame: before the first session (which is in the first week), after the tenth session (which is in the fifth week), and the three weeks later after the end of the treatment (which is in the eighth week)
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
A questionnaire developed to evaluate the condition of patients with osteoarthritis of the knee and hip, including pain, stiffness, and physical functioning of the joints.
Time frame: before the first session (which is in the first week), after the tenth session (which is in the fifth week), and the three weeks later after the end of the treatment (which is in the eighth week)
The survey of Chinese medical body constitution
The scores of the Chinese medical body constitution can tell the difference of the subjects' physical fitness.
Time frame: 30 min before the first acupuncture treatment
