ABSTRACT
ObjectiveStudy on the mechanism of Guishao Yunpi decoction in preventing and treating breast hyperplasia based on phosphatase and tensin homolog （PTEN）/ phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodSeventy SPF-grade SD rats were randomly assigned into blank group （n=15） and modeling group （n=55）. The mammary gland hyperplasia model of liver stagnation and spleen deficiency was established by the comprehensive modeling method （hunger and satiety abnormality + tail stimulation + estradiol benzoate + progesterone）， and then 5 rats were randomly selected for model verification. The modeled rats were then randomly assigned into five groups： model group， positive control （4 mg·kg-1·d-1 tamoxifen） group， and high-， medium-， and low-dose （17.2， 8.6， 4.3 g·kg-1·d-1， respectively） Guishao Yunpi decoction groups， with 10 rats in each group. The rats in the blank group and model group were given 10 mL·kg-1·d-1 distilled water， and those in other groups were orally administrated with corresponding drugs. After 30 days of treatment， the general living conditions of rats were observed， and the thickness of breast tissue was measured by an ultrasonic diagnostic instrument. The open field test was carried out for behavioral evaluation. The levels of B-cell lymphoma-2 （Bcl-2） and Bcl-2-associated X （Bax） in the breast tissue were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein levels of PTEN， PI3K， and Akt in the breast tissue were determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultCompared with those in the blank group， the rats in the model group were irritable， curled up in clusters， and showed positive behavior in the open field test. The modeling led to nipple swelling and increased the breast thickness （P<0.05）. Moreover， the modeling elevated the level of Bcl-2 and lowered that of Bax in the breast tissue （P<0.05）， down-regulated the mRNA and protein levels of PTEN， and up-regulated the mRNA and protein levels of PI3K and Akt （P<0.05）. Compared with the model group， drug administration relieved the general survival state， the degree of nipple swelling， and the positive behavior in the open field test and reduced the breast thickness （P<0.05）. In addition， drug administration reduced the level of Bcl-2 and increased that of Bax in the breast tissue （P<0.05）， up-regulated the mRNA and protein levels of PTEN， and down-regulated the mRNA and protein levels of PI3K and Akt （P<0.05）. ConclusionGuishao Yunpi decoction can improve the general living conditions and alleviate the mammary gland hyperplasia of rats with the syndrome of liver depression and spleen deficiency， which may be realized by the regulation of the PTEN/PI3K/Akt pathway.

ABSTRACT
Objective The experiment was designed to study the therapeutic mechanism of "Tong Tiao" acupuncture in the treatment of mammary gland hyperplasia (MGH) on the rat model.Methods A total of 75 healthy unpregnant female SD rats were randomly divided into six groups: blank, model, control group, vagus cutting therapy, sham operation, and vagus cutting with non-treatment group. All the groups except the blank group were prepared by MGH rat model. The vagus cutting therapy and vagus cutting with non-treatment group were treated by cutting the right cervical vagus nerve, while the sham operation group was treated by exposing the vagus nerve without any operation. All the treatment groups were treated with "Tong Tiao". The rat papillary height was measured. The breast tissue morphology and breast ultrastructure were observated. And the flow cytometry in rat peripheral blood T lymphocyte subsets CD3+, CD4+, CD8+, CD4+/CD8+ were calculated. Results Compared with the model group, the papillary height (1.22 mm ± 0.21 mm,1.24 mm ± 0.20 mmvs. 1.53 mm ± 0.16 mm) in the normal treatment and the sham treatment group decreased significantly the vagus cutting therapy and vagus cutting non-treatment group showed no difference (P>0.05). Compared with the model group, the Mammary gland morphology and ultrastructure in the normal treatment group, the sham operation group and the vagus cutting therapy groups were improved, but the vagus cutting non-treatment group showed on improvement. Compared with model group, the serum CD3+(61.5％ ± 10.5％, 61.1％ ± 12.4％, 59.8％ ± 11.8％vs. 57.7％ ± 9.4％), CD4+(37.2％ ± 8.9％, 37.9％ ± 10.9％, 36.1％ ± 12.2％ vs. 34.6％ ± 6.9％), CD4+/CD8+(1.59 ± 0.8, 1.58 ± 0.8, 1.38 ± 0.6vs. 1.23 ± 0.7) in the normal treatment group, the sham treatment group and vagus cutting therapy group, elevated significantly (P<0.01,P<0.05), while the vagus cutting non-treatment group showed no difference (P>0.05). Compared with model group, the serum CD8+ (24.2％ ± 11.3％, 24.5％ ± 10.6％,25.5％ ± 8.8％vs. 27.7％ ± 9.9％) in the normal treatment group, sham treatment group and vagus cutting therapy group decreased significantly lower (P<0.01,P<0.05), but vagus cutting non treatment group showed no difference (P>0.05). Conclusions the mechanism of acupuncture treatment for MGH may be related to the vagus nerve by regulating the CD3+, CD4+, CD8+ and CD4+/CD8+ levels of T lymphocytes.

ABSTRACT
OBJECTIVE: To observe the effect of acupuncture combined with medication (Rule Granule) on serum prolactin (PRL)，estradiol (E2) and progestone (P) contents and expressions of prolactin receptor (PRLR), estrogen receptor (ER) and progestrone receptor (PR) proteins in mammary gland (MG) tissues of MG hyperplasia (MGH) rats, so as to explore its mechanisms underlying improvement of MGH. METHODS: A total of 55 female SD rats were randomized into blank control group (n＝10), model group (n＝10), acupuncture group (n＝11), medication group (n＝10), and acupuncture plus medication group (n＝9). The MGH model was established by muscular injection of E2 benzoate(0.5 mg/kg, once daily for 20 days), followed by injection of P (5 mg/kg) into the lateral muscle of the hind-limb, once daily for 5 days, and the rats of the control group were treated by muscular injection of normal saline at the same site and in the same procedures. Acupoint group A composed of bilateral Tianzhong (SI 11), Ganshu (BL 18) and Zusanli (ST 36), and group B composed of Tanzhong (CV 17), and bilateral Wuyi (ST 15) and Hegu (LI 4) were alternatively punctured with filiform needles and stimulated swiftly by twirling the needle in each acupoint for 20－30 sec, once daily for 30 days. Rats of the medication group and acupuncture ＋medication group were treated by gavage of Rule Granule fluid containing Baishao (Paeonia Iactiflora Pall), Danggui (Angelica sinensis), etc. (1.5 mL/100 g for each rat) and those of the other groups treated by gavage of distilled water (1.5 mL/100 g). The treatment was given once daily for continuous 30 d. At the end of the experiments, the rats' abdominal aorta blood was collected for assaying the contents of serum PRL, E2 and P with ELISA, and the pathological changes of breast tissue (the left 2nd pairs) were observed under microscope after sectioning and H．E. staining. The expression of PRLR, ER and PR proteins in the breast tissue was detected by immunohistochemistry. RESULTS: After modeling, the hyperplasia of mammary gland in the model group was obvious; the serum PRL and E2 contents and the immunoactivities of PRLR, ER and PR were significantly increased (P0.05)．. CONCLUSION: Acupuncture, Rule Granule, and acupuncture combined with Rule Granule can improve hyperplasia of mammary gland in rats, which may be related to their effects in reducing serum PRL and E2 and breast ER, PR and PRLR expression levels, and in increasing serum P level. The therapeutic effects of acupuncture plus Rule Granule are better than those of simple acupuncture and simple Rule Granule.
ABSTRACT
OBJECTIVE: To observe the effect of electroacupuncture (EA) intervention on hyperplastic mammary glands, serum estradiol (E2) and progesterone (P) contents, estrogen receptor alpha (ERα) and progesterone receptor (PR) expression of breast tissues in mammary gland hyperplasia (MGH) rats, so as to reveal its mechanisms underlying improvement of MGH. METHODS: Sixty female SD rats were randomly divided into control, model, EA, EA＋ovariectomy(OVX) and EA＋sham-OVX groups (n＝12 in each). The MGH model was established by injection of Estradiol Benzoate injection (0.5 mg/kg, once daily for 25 d) and P injection (0.5 mg/kg, once daily for 5 d after estradiol injection) into the medial hind-leg muscle. After model establishment, bilateral OVX was performed for rats of the EA＋OVX group, and sham OVX (only exposure of ovaries) was performed for rats of the EA＋sham OVX group. EA (2 Hz, 2 mA) was applied to bilateral "Tianzong"(SI 11), "Ganshu"(BL 18), "Zusanli" (ST 36) for point group A, and "Wuyi"(ST 15), "Hegu"(LI 4), "Danzhong" (CV 17) for point group B for 20 min, once daily, 5 days a week for 4 weeks. The two acupoint groups were used alternately. The height of the rats' nipples (the 2nd pairs) were measured. Serum E2 and P levels were assayed by ELISA. The expression of ERα and PR in mammary tissues was detected by immunofluorescence staining and Western blot, separately. RESULTS: The height of nipples, serum E2content, and mammary ERα protein expression level were significantly higher in the model group than in the control group (P0.05), suggesting an important role of the ovary in producing EA's effect. CONCLUSION: EA intervention can improve hyperplastic mammary glands by down-regulating serum E2content and mammary ERα protein expression, and up-regulating serum P content and PR expression in MGH rats, which has a close relation with the intact ovaries.
ABSTRACT
Objective:To explore and analyze the points-selection rules in acupuncture treatment of mammary gland hyperplasia (MGH) by data mining and statistical method. Methods:Clinical literatures about the treatment of MGH with acupuncture published in the recent 16 years were retrieved from Chinese Journal Full-text Database (CJFD) and established into a database by Excel. The SPSS 20 version software and Clementine 12.0 version software were adopted to analyze the frequency and association rules of points-selection in the treatment of MGH with acupuncture. Results:The top 3 points used most frequently in acupuncture treatment of MGH were Danzhong (CV 17), Taichong (LR 3) and Zusanli (ST 36); points from the Stomach Meridian of Foot Yangming and Liver Meridian of Foot Jueyin were most commonly used; the commonly selected points were predominantly distributed in thoracic and abdominal regions and lower limbs; emphasis on the combination use of local and distal points; of the specific points, the five Shu-Transmitting points were mostly used; association analysis showed that the associations among Taichong (LR 3), Danzhong (CV 17) and Zusanli (ST 36) were the most significant. Conclusion: The data mining results substantially accord with the general rules of acupuncture-moxibustion theories in traditional Chinese medicine, able to reflect the points-selection principles and features in acupuncture treatment of MGH and provide evidence for the points selection in the treatment of MGH in acupuncture clinic.
