Hypoglycemic effect of electroacupuncture at "Tianshu" (ST 25) combined with metformin on rats with type 2 diabetes mellitus based on AMPK / 中国针灸

OBJECTIVE@#To observe the hypoglycemic effect of electroacupuncture (EA) at "Tianshu" (ST 25) combined with metformin on rats with type 2 diabetes mellitus (T2DM) as well as its effect on expression of adenosine monophosphate activated protein kinase (AMPK) in liver and pancreas.@*METHODS@#Thirty-six male SD rats were randomly divided into a blank group (6 rats) and a model establishing group (30 rats). The rats in the model establishing group were fed with high-fat diet and treated with intraperitoneal injection of low-dose streptozotocin (STZ) to establish T2DM model. The rats with successful model establishment were randomly divided into a model group, a control group, a metformin group, an EA group and a combination group, 6 rats in each group. The rats in the EA group were treated with EA at "Tianshu" (ST 25), dense-disperse wave, 2 Hz/15 Hz in frequency and 2 mA in current intensity, 20 min each time. The rats in the metformin group were treated with intragastric administration of metformin (190 mg/kg) dissolved in 0.9% sodium chloride solution (2 mL/kg). The rats in the combination group were treated with EA at "Tianshu" (ST 25) and intragastric administration of metformin. The rats in the control group were treated with intragastric administration of 0.9% sodium chloride solution with the same dose. All the treatments were given once a day for 5 weeks. After the intervention, the body mass and random blood glucose were detected; the serum insulin level was detected by ELISA; the expression of AMPK and phosphorylated adenosine monophosphate activated protein kinase (p-AMPK) in liver and pancreas was detected by Western blot method; the expression of protein gene product 9.5 (PGP9.5) was detected by immunofluorescence.@*RESULTS@#①Compared with the blank group, the body mass in the model group was decreased (P<0.05); compared with the model group, the body mass in the EA group and the combination group was decreased (P<0.05); the body mass in the EA group and the combination group was lower than the metformin group (P<0.05). Compared with the blank group, the random blood glucose in the model group was increased (P<0.01); compared with the model group, the random blood glucose in the metformin group, the EA group and the combination group was decreased (P<0.01). The random blood glucose in the combination group was lower than the metformin group and the EA group (P<0.05). ②Compared with the blank group, the insulin level in the model group was decreased (P<0.05); compared with the model group, the insulin level in the metformin group, the EA group and the combination group was all increased (P<0.05). The insulin level in the combination group was higher than the metformin group and the EA group (P<0.05). ③Compared with the blank group, the protein expression of AMPK and p-AMPK in liver tissue was decreased (P<0.05), and the protein expression of AMPK and p-AMPK in pancreatic tissue was increased (P<0.05) in the model group. Compared with the model group, the protein expression of AMPK and p-AMPK in liver tissue in the metformin group, the EA group and the combination group was increased (P<0.05, P<0.01); the protein expression of AMPK in pancreatic tissue in the metformin group was increased (P<0.05); the protein expression of AMPK in pancreatic tissue in the EA group and the combination group was decreased (P<0.05); the protein expression of p-AMPK in pancreatic tissue in the metformin group, the EA group and the combination group was decreased (P<0.05). The protein expression of AMPK and p-AMPK in liver tissue in the combination group was higher than that in the metformin group and the EA group (P<0.05); the protein expression of AMPK in pancreatic tissue in the EA group and the combination group was less than that in the metformin group (P<0.05), and the expression of p-AMPK protein in pancreatic tissue in the combination group was less than that in the metformin group and the EA group (P<0.05). ④Compared with the blank group, the expression of PGP9.5 in pancreatic tissue in the model group was increased (P<0.01); compared with the model group, the expression of PGP9.5 in pancreatic tissue in the metformin group, the EA group and the combination group was decreased (P<0.05, P<0.01). The expression of PGP9.5 in pancreatic tissue in the EA group was lower than the metformin group and the combination group (P<0.05).@*CONCLUSION@#Electroacupuncture at "Tianshu" (ST 25) could promote the effect of metformin on activating AMPK in liver tissue of T2DM rats, improve the negative effect of metformin on AMPK in pancreatic tissue, and enhance the hypoglycemic effect of metformin. The mechanism may be related to the inhibition of pancreatic intrinsic nervous system.

Effects of acupuncture combined withgranule on breast tissue, prolactin and receptor expression in rats with mammary gland hyperplasia / 中国针灸

<p><b>OBJECTIVE</b>To observe the effects of acupuncture combined withgranule on breast tissue, prolactin(PRL) and prolactin receptor (PRLR) expression in rats with mammary gland hyperplasia (MGH), and to explore its action mechanism to provide reference for clinical treatment of MGH.</p><p><b>METHODS</b>Fifty-five female SD rats were randomly divided into a blank group, a model group, an acupuncture group, a Rule granule group and a combination group. Except the blank group, the rats in the remaining groups were treated with combined stimulation of estrogenic and progestational hormone to establish MGH model. After model establishment, the rats in the acupuncture group were treated with acupuncture at Plan A of "Tianzong" (SI 11), "Ganshu" (BL 18), "Zusanli" (ST 36) and Plan B of "Wuyi" (ST 15), "Hegu" (LI 4), "Danzhong" (CV 17). Each plan was selected for one acupuncture treatment, and two plans were used alternately. The rats in the Rule granule group were treated with oral administration of granule, 3 mL per times. The rats in the combination group were treated with the samegranule, followed by acupuncture, once a day. After consecutive 30-day treatment, blood sample was collected from abdominal aorta; ELISA method was applied to measure the contents of PRL; the HE slice of mammary gland was observed under light microscope; the SABC immunohistochemical method was applied to measure the positive expression of PRLR.</p><p><b>RESULTS</b>The morphology of breast tissue in the model group was consistent with MGH. Compared with the blank group, the serum PRL and the expression of PRLR were increased significantly in the model group (both<0.01). Compared with the model group, the hyperplasia of mammary gland in each treatment group was improved, and serum PRL and expression of PRLR were significantly reduced (<0.05,<0.01), which were more significant in the combination group (both<0.05).</p><p><b>CONCLUSION</b>Acupuncture,granule and its combination could effectively treat MGH, which is likely to reduce the level of serum PRL and inhibit the binding of PRL to PRLR, as a result, the level of Eis indirectly inhibited, and the hyperplastic mammary gland is recovered. Compared with acupuncture orgranule, the combination of both has better overall efficacy.</p>
