[Abstract]:Objective: To study the expression effect of caffeine on inflammatory pain and the analgesic effect of acupuncture and pain related hypothalamic molecules. Methods: C57BL/6J mice as the research object, screening based thermal pain threshold at 10 s ~ 20 s mice were randomly divided into control group, model group, model + EA group (referred to as the EA group, model +) electroacupuncture + caffeine group (referred to as die coffee needle group); preparation of inflammatory pain model using intraplantar injection of complete Freund's adjuvant; model acupuncture group 70 mg/Kg/day caffeine coffee intake, blank group, model group, EA group drinking water; electro acupuncture group, model group of electric needle needle coffee intervention, 2/100Hz density wave 0.2mA, 15 minutes, 1 times per day, 11 days of continuous intervention; the radiant heat was measured the pain threshold measured pain, after the end of treatment were used to detect the expression of animal in the hypothalamus Array pain PCR high-throughput detection technology related molecules. Results: (1) caffeine on inflammatory pain The effect of acupuncture analgesia: comparison between groups: 3 days after modeling, compared with the blank group, model group, electro acupuncture group and acupuncture group die coffee pain threshold of mice decreased significantly, the difference was statistically significant (P0.000), and model group, EA group and coffee needle group differences between the three groups was not statistically meaning (P0.05), comparable. In the model after 7 days, there was statistical significance of EA group and model group (P0.000); pain threshold difference was not statistically significant. Coffee needle group and the model group difference threshold (P0.05); the difference mode coffee needle group and electro acupuncture group had statistical significance (P0.000). At 13 and 14 days, there was statistical significance of EA group and model group (PO.000), the pain threshold difference was not statistically significant. Coffee needle group and model group (P0.05), the pain threshold difference there was statistically significant difference between the model group and EA group coffee needle group (P0.001). Comparison: in the rats of model group 鍚，
