RÉSUMÉ

The present study aimed to investigate the protective role of Shaofu Zhuyu Decoction(SFZY) against endometriosis fibrosis in mice, and decipher the underlying mechanism through the phosphatase and tensin homolog deleted on chromosome ten(PTEN)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR) pathway. Eighty-five BALB/c female mice were randomly assigned into a blank group, a model group, high-, medium, and low-dose SFZY(SFZY-H, SFZY-M, and SFZY-L, respectively) groups, and a gestrinone suspension(YT) group. The model of endometriosis was induced by intraperitoneal injection of uterine fragments. The mice in different groups were administrated with corresponding groups by gavage 14 days after modeling, and the blank group and model group with equal volume of distilled water by gavage. The treatment lasted for 14 days. The body weight, paw withdrawal latency caused by heat stimuli, and total weight of dissected ectopic focus were compared between different groups. The pathological changes of the ectopic tissue were observed via hematoxylin-eosin(HE) and Masson staining. Real-time PCR was employed to measure the mRNA levels of α-smooth muscle actin(α-SMA) and collagen type Ⅰ(collagen-Ⅰ) in the ectopic tissue. The protein levels of PTEN, Akt, mTOR, p-Akt, and p-mTOR in the ectopic tissue were determined by Western blot. Compared with the blank group, the modeling first decreased and then increased the body weight of mice, increased the total weight of ectopic focus, and shortened the paw withdrawal latency. Compared with the model group, SFZY and YT increased the body weight, prolonged the paw withdrawal latency, and decreased the weight of ectopic focus. Furthermore, the drug administration, especially SFZY-H and YT(P<0.01), recovered the pathological and reduced the area of collagen deposition. Compared with the blank group, the modeling up-regulated the mRNA levels of α-SMA and collagen-Ⅰ in the ectopic focus, and such up-regulation was attenuated after drug intervention, especially in the SFZY-H and YT groups(P<0.05,P<0.01). Compared with the blank group, the modeling down-regulated the protein level of PTEN and up-regulated the protein levels of Akt, mTOR, p-Akt, and p-mTOR(P<0.01, P<0.001). Drug administration, especially SFZY-H and YT, restored such changes(P<0.01). SFZY may significantly attenuate the focal fibrosis in the mouse model of endometriosis by regulating the PTEN/Akt/mTOR signaling pathway.

RÉSUMÉ

ObjectiveTo evaluate the clinical curative effect of modified Shaofu Zhuyutang on pelvic pain of endometriosis (EMT) with syndrome of cold congeal and blood stasis and the influence on neural angiogenesis. MethodA total of 110 cases were divided into a control group (54 cases) and an observation group (56 cases) by the random number table method. Patients in the control group took Aifu Nuangong pills with 6 g/time and 2 times/day. Patients in the observation group took modified Shaofu Zhuyutang with 1 dose/day. Course of treatment continued for 3 menstrual cycles. Dysmenorrhea, other symptoms and signs of pelvic pain, and the EMT health profile-5 (EHP-5) for patients with syndrome of cold congeal and blood stasis and EMT were scored before and after treatment. The levels of peripheral blood nerve growth factor (NGF), substance P (SP), calcitonin gene-related peptide (CGRP), brain-derived neurotrophic factor (BDNF), soluble Fms-like tyrosine kinase(sFlt-1), vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9), and insulin growth factor-1 (IGF-1) were detected before and after treatment. The levels of prostaglandin E2 (PGE2), cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and other inflammatory factors were detected before and after treatment. The pain medication usage and recurrence were recorded. ResultThe scores of dysmenorrhea, symptoms of pelvic pain symptoms (non-menstrual pelvic pain, dyspareunia, anal falling pain, and defecation pain, etc.), and signs of pelvic pain (pelvic tenderness and sacral ligament tender nodules) in the observation group were lower than those in the control group (P<0.01). The disappearance rates of dysmenorrhea, pelvic tenderness, and sacral ligament tender nodules were 67.35% (33/49), 73.33% (33/45), and 77.27% (34/44) in the observation group, which were all higher than 45.83% (22/48), 48.84% (21/43), and 52.27% (23/44) in the control group. The difference was statistically significant (χ2=4.571, χ2=5.565, χ2=6.026, P<0.05). The scores of EHP-5 and syndrome of cold congeal and blood stasis in the observation group were lower than those in the control group (P<0.01). The levels of VEGF, MMP-9, IGF-1, NGF, SP, CGRP, and BDNF in the observation group were lower than those in the control group (P<0.01), while the level of sFlt-1 was higher than that in the control group (P<0.01). The levels of PGE2, COX-2, TNF-α, and IL-6 in the observation group were lower than those in the control group (P<0.01). The total effective rate of the observation group was 92.45% (49/53), which was higher than 76.00% (38/50) of the control group (χ2=5.307, P<0.05). After 6 months of follow-up, the recurrence rate in the observation group was 30.61% (15/49), which was lower than 52.63% (20/38) in the control group (χ2=4.315, P<0.05). The average of taking ibuprofen sustained-release capsules in the control group was higher than that in the observation group per menstrual period (P<0.01). ConclusionModified Shaofu Zhuyutang treated pelvic pain of EMT with syndrome of cold congeal and blood stasis by regulating the mechanism of neural angiogenesis, reducing pain, and promoting the disappearance of related pains, thus improving the quality of life. Shaofu Zhuyutang has a better clinical effect than Aifu Nuangong pills and has a low recurrence rate.
