ABSTRACT
ObjectiveTo investigate the mechanism of Chaihu Qinggantang （CHQGT） in the treatment of granulomatous lobular mastitis （GLM） in the rat model. MethodSixty female rats were divided into a normal group， a model group， a prednisolone group （0.001 8 g·kg-1）， and three CHQGT low-dose， medium-dose， and high-dose groups （4.5， 8.9， 17.8 g·kg-1）. The tissue homogenates mixed with GLM lesion tissue and Fritner's reagent were used for modeling. After modeling， the treatment groups were given corresponding treatment factors， and the normal group and the model group were given the equal volume of normal saline. The changes in mammary gland of rats were observed after 14 d. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in breast samples. The mRNA expressions of NOD-like receptor thermal protein domain associated protein 3 （NLRP3） inflammasome， Caspase-1， and interleukin-1β （IL-1β） were detected by real-time quantitative fluorescence polymerase chain reaction （Real-time PCR）. The protein expressions of NLRP3， Caspase-1， IL-1β， and IL-18 were detected by Western bolt. ResultAs compared with the normal group， the breasts of rats in the model group were obviously swelling， and mammary gland inflammation index was significantly increased （P<0.01）. Pathological changes included the formation of granuloma centered on the lobule of mammary gland with a large number of inflammatory cells such as lymphocytes and plasma cells. The mRNA expressions of NLRP3， Caspase-1， and IL-1β， and the protein expressions of NLRP3， Caspase-1， IL-1β， and IL18 in the model group were significantly increased （P<0.01）. Compared with the model group， the treatment groups improved breast swelling， and the CHQGT medium and high-dose groups and the prednisolone group reduced inflammation index to some extent after treatment （P<0.05， P<0.01）. The inflammation degree of mammary gland was significantly improved， and inflammatory cells such as macrophages， lymphocytes， and plasma cells were reduced to varying degrees in pathological aspects. The mRNA expressions of NLRP3， Caspase-1， and IL-1β， and the protein expressions of NLRP3， Caspase-1， IL-1β， and IL-18 in the CHQGT high-dose group and the prednisolone group were significantly down-regulated （P<0.05， P<0.01）. ConclusionCHQGT inhibits inflammation and treats GLM in rats. The mechanism is possibly related to the inhibition of NLRP3/IL-1β signaling pathway， which provides a new target for the prevention and treatment of GLM by Qingxiao method.
ABSTRACT
Resumen OBJETIVO: Describir las características clínicas de la mastitis granulomatosa idiopática y exponer los esquemas de tratamiento indicados a una serie de pacientes. MATERIAL Y MÉTODOS: Estudio retrospectivo y transversal efectuado en una serie de casos de pacientes con mastitis granulomatosa idiopática atendidas entre mayo de 2012 y julio 2013 por el Grupo de Alta Especialidad Ginecológica y Mamaria de la Ciudad de México. A todas las pacientes se les tomó una biopsia escisional, justificada y guiada por un estudio radiológico previo. RESULTADOS: Se incluyeron 21 pacientes de edad promedio de 42 años (DE ± 12.5 años) 7 de 21 estaban en la menopausia, 3 de 21 habían permanecido asintomáticas, 2 de 21 con telorragia, 14 de 21 con tumoración mamaria y 2 de 21 con mastalgia. El reporte radiológico de BIRADS fue: 3 = III, 8 = IVa, 8 = IVb y 2 = IVc. La resección quirúrgica se practicó a 19 de 21 pacientes y a 14 de 19 se les administró, antes de la operación, prednisona. CONCLUSIONES: La combinación del tratamiento médico y quirúrgico mejora el pronóstico funcional y cosmético de las pacientes con mastitis granulomatosa y disminuye el riesgo de coincidencia inadvertida de carcinoma de mama.
Abstract OBJECTIVE: To describe the clinical characteristics of the patients studied with Mastitis idiopathic granulomatous (MGI), also to provide therapeutic tools for these kind of patients. MATERIAL AND METHODS: Retrospective cross-sectional study of 21 patients with MGI who underwent excision, justified and guided by a previous radiological study, with a complete file and a histopathology report that confirmed the pathological entity. Results: We included 21 patients with an average age of 42 years (SD +/- 12.5 years) 7/21 were in the menopause stage. The clinical presentation was: 3 asymptomatic, 2 with sporulation, 14 with mammary tumor and 2 with mastalgia. The radiological report of BIRADS was: 3 = III, 8 = IVa, 8 = IVb and 2 = IVc. Surgical resection was performed at 19/21 and at 14/19, prednisone was administered preoperatively. CONCLUSIONS: The combined use of medical and surgical treatment improves the functional and cosmetic prognosis in the patient, as well as decreases the risk of inadvertent coincidence of a breast carcinoma.
ABSTRACT
Objective To investigate the effectiveness of glucocorticoids in the treatment of granulomatous lobular mastitis (GLM), and to discuss the optimal stage to add glucocorticoids during the treatment. Methods Twenty-four patients having received the core needle biopsy were involved. Ten cases with the explicit pathological diagnosis received the glucocorticoids therapy following the subtotal excision after remission. Pathological diagnoses of the rest 14 patients were undefined. For these 14 patients, simple partial excisions were given and the postoperative pathological diagnoses were presented as the GLM. Of all the 14 patients who accepted the surgical treatment firstly, 8 patients received the postoperative glucocorticoids adjuvant therapy. For the rest 6 patients, steroid hormone therapy was not used after surgery, and they were followed up postoperatively. All patients' clinical and pathological information were collected and analyzed. Results All patients were followed up for 6-36 months (average 18) by the outpatient service. Of all the 10 patients who received the glucocorticoids therapy before surgery, only 1 patient of them got the GLM recurrence. For the 8 patients who received the postoperative glucocorticoids treatment, only 1 patient got the recurrence. For the 6 patients who received simple partial excision, the recurrence of the GLM may be up to 3. There was no statistical difference between the two groups who both received the 05). But compared with the pure surgery treatment, the difference was obviously (P<0.05). Conclusions The clinical presentation and imaging performance of GLM are unspecific, so the diagnosis of the GLM is difficult. There is no consensus regarding the optimal treatment for GLM. The glucocorticoids therapy may be necessary preoperatively or postoperatively. For the patient with clear preoperative biopsy diagnosis, preoperative glucocorticoids adjuvant chemotherapy followed by the wide excision may be an effective method.
ABSTRACT
Objective To observe the effect of different methods such as combined treatment of traditional Chinese and western medi-cine, the simple excision and expanded resection for the treatment of granulomatous lobular mastitis. Methods 60 cases of patients treated in our hospital from Jan. 2010 to Jan. 2013 were enrolled in this study, and they were confirmed the diagnosis of granulomatous lobular mas-titis by pathology examination. According to randomly number table, they were divided into three groups and they were given the treatment of combined treatment of traditional Chinese medicine and Western medicine, the simple excision, and expanded resection respectively. Where-after, the therapeutic effect of the three groups were observed. Results There were 9 cases (45. 0%) were of cure and 11 cases (55. 0%) of recurrence in the combined treatment group. There were 16 cases (80. 0%) of cure and 4 cases (20. 0%) of recurrence in the simple ex-cision group. There were 8 cases (90. 0%) of cure and 2 cases (10. 0%) of recurrence in the combined treatment group. It shows that the recurrence rate of combined treatment group was higher than the other two groups (P0. 05). Conclusion The effect of extended resectionin for the treatment of granulomatous is better and it has important clinical value.
