ABSTRACT
Objective To observe the effect of Rule Granules on the breast tissue pathology,ovarian hormone and receptor expression of mammary glands hyperplasia rats; To explore its mechanism of action. Methods The model of mammary gland hyperplasia was established by intramuscular injection of estradiol benzoate for 20 days and intramuscular injection of progesterone for 5 d. 66 female SD rats were randomly divided into 6 groups, including blank group, model group, acupuncture group, TCM high-, medium- and low-dose groups, with 11 rats in each group. Acupuncture group chose group A (Wuyi, Hegu, on both sides, Tanzhong) and group B (Tianzong, Ganshu, Zusanli, on both sides), and the two groups were used alternately, one group per day. TCM groups received 1.1 g/mL, 0.55 g/mL,and 0.11 g/mL dose of Rule Granules for gavage,once a day.Abdominal aorta blood was collected after continuous treatment of 30 d. The contents of serum E2and P were detected through ELISA method, at the same time, the second left side of the breast was removed. The changes of the breast tissue was observed under light microscope, and the ER and PR positive expression was observed by SABC immunohistochemical method. Results Compared with the blank group, hyperplasia of mammary gland in the model group rats was more obvious, and serum E2, ER and PR positive expression of integral increased significantly (P<0.01), but the content of P decreased significantly (P<0.01); compared with the model group, hyperplasia of mammary gland was improved in all treatment groups, and serum E2, ER and PR positive expression of integral decreased significantly (P<0.05); the content of P in acupuncture group increased significantly (P<0.01), and the acupunture group and TCM low-dose group were the most obvious. Conclusion Rule Granules can effectively improve hyperplasia of mammary gland organization structure in rats caused by exogenous estrogen and progesterone, with TCM low-dose group and acupuncture group having the best efficacy. Its mechanism is related to reducing the contents of serum E2and ER, and PR positive expression in breast tissue, and increasing the content of serum P.

ABSTRACT
<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>
ABSTRACT
To introduce the experience of professorfor mammary gland hyperplasia by disease-symptom diagnosis and treatment. Under disease-symptom combination and the reference of both Chinese medicine and western medicine,he took priority in diagnosis and then treated diseases by acupuncture and medicine,etc. Meanwhile,he considered the superficiality and origin of diseases and served patients based on individuals,seasons and regions. Also,regulation for mood was applied. As a result, the good effect was achieved.
