Study on the Anti-Inflammatory and Analgesic Mechanisms of Breast Lump Resolution Detergent in a Rat Model of Breast Hyperplasia

Objective: This study aimed to investigate the anti-inflammatory and analgesic mechanisms of a breast lump resolution detergent in a rat model of breast hyperplasia. Methods: A rat model of breast hyperplasia was established using injections of estradiol benzoate combined with progesterone. The effects of the breast lump resolution detergent on nipple height and diameter in the rat model were observed, along with its impact on serum levels of estradiol (E2), prolactin (PRL), and progesterone (P). Additionally, the study examined the morphological changes in breast tissue. The impact of the breast nodule detergent on blood rheology parameters was also observed. Furthermore, the anti-inflammatory effect of the breast nodule detergent was assessed using the cotton ball granuloma experiment, and the analgesic effect was observed using the writhing test. Results: The breast lump resolution detergent reduced nipple height and diameter in the rat model, decreased serum levels of E2, PRL, and P, and alleviated pathological changes in breast tissue. It also lowered hemorheological parameters including whole blood high, medium, and low shear viscosity, plasma viscosity, red blood cell hematocrit, red blood cell aggregation index, red blood cell deformability index, red blood cell electrophoresis time, and erythrocyte sedimentation rate in the acute “blood stasis” rat model. The detergent reduced the weight of cotton ball granulomas in mice and decreased the number of writhing episodes caused by acetic acid. Conclusion: The breast lump resolution detergent demonstrates favorable therapeutic effects in treating breast hyperplasia, promoting blood circulation and removing blood stasis, exerting anti-inflammatory properties, and providing analgesic effects. The downregulation of serum E2 and PRL levels and the upregulation of P levels may be critical mechanisms underlying its efficacy.

EFFECT OF CALCITONIN GENE-RELATED PEPTIDE ON PROGESTERONE AND ESTRADIOL PRODUCTION OF RAT OVARIAN CELLS in vitro

Calcitonin gene-related peptide (CGRP) is a newly discovered bioactive peptide which consists of 37 amino acids. CGRP is widely distributed in the nervous system as well as in peripheral organs. It has various effects on CNS, cardiovascular, gastrointestinal, bronchotracheal and endocrine systems. CGRP-containing nerve fibres exist in hypothalumus, pituitary gland and urinogenital systems which are closely related to reproductive func-

Higher IL-8 Response to <i>Mycobacterium tuberculosis</i>Antigens in Women above 40 Years

Objective: Circulating levels of sex hormones vary with age. Moreover, there is emerging evidence supporting that sex hormones have an influence on the immune response of women. Here, we investigated age-associated levels of sex hormones and Mycobacterium tuberculosis (Mtb) specific cytokines response in women. Design: Using immunoassay methods, we have measured and compared secretion levels of E2, P4 and Mtb specific secretion of 11 cytokines including Granulocyte-macrophage colony-stimulating factor (GM-CSF), Interferon gamma (IFN-γ), Interleukin 1 beta (IL-1β), IL-10, IL-12 (p70), IL-2, IL-4, IL-5, IL-6, IL-8, and Tumor necrosis factor (TNF-α) in forty-two (42) HIV-negative females. Results: Estradiol (E2) and progesterone (P4) levels were significantly higher in younger women irrespective of their LTB status (p < [0.0001 - 0.05]). Mtb IL-8 specific response was significantly higher in women above 40 years old than in women under 40 years old. Conclusion: In premenopausal women, there is an increase in the pro-inflammatory cytokine IL-8 secretion in response to Mtb-antigen. This observation suggests an underlying link between the pro-inflammatory cytokine and age associated hormonal changes, which may have implications on the course of tuberculosis infection women.

异位灵对子宫内膜异位症内分泌激素水平影响的研究

目的 :探讨内分泌激素在内异症发病中的作用及异位灵对子宫内膜异位症机体神经—内分泌—免疫网络功能的影响。方法 :手法移植法造SD大鼠内异症模型 ,同时与正常组、异位灵组、西药丹那唑对照组比较。用放免法测各组血中E2 、P、ACTH、Cr的水平变化。结果 :模型组中E2 水平显著高于正常组 ,P、ACTH、Cr水平显著低于正常组 (P <0 0 1或P <0 0 5 )。异位灵降调了E2 水平 ,升调了P、Cr水平 (P <0 0 1)。西药组只对E2 、P有降、升调作用 (P <0 0 5 ) ,对Cr的升调作用没有统计学意义。两组对ACTH虽有升调作用 ,但没有统计学意义。结论 :内分泌功能紊乱在内异症发病中占有重要作用 ,异位灵治疗子宫内膜异位症的疗效优于西药组 ,其机理可能是通过调节机体神经—内分泌—免疫网络功能而发挥作用的。

桂枝茯苓丸抗大鼠子宫肌瘤作用机制研究

目的:探讨桂枝茯苓丸治疗子宫肌瘤模型大鼠的作用机制。方法:60只成年雌性SD大鼠随机分为4组:分为空白(Control)组、模型(Hys)组、桂枝茯苓丸低剂量(G-L)组、桂枝茯苓丸高剂量(G-H)组,每组15只。除假手术组外,其余3组均进行子宫肌瘤造模。G-L组、G-H组分别接受浓度为1.32 g/mL、2.64 g/mL的桂枝茯苓丸混悬液1 mL灌胃,其中Control组及Hys组大鼠给予等剂量生理盐水灌胃,1次/d,连续8周。记录各组大鼠子宫及卵巢系数,HE染色观察子宫形态学变化,透射电镜观察子宫超微结构变化,ELISA法检测子宫组织E2、P、ER含量,Western Blot法检测子宫组织中PI3K/Akt信号通路蛋白表达情况。结果:与Control组比较,Hys组的子宫和卵巢系数、E2、P、ER的含量及抗凋亡蛋白PI3K、p-Akt表达增高(P<0.05),促凋亡蛋白Caspase-3表达减少(P<0.05),G-L组、G-H组上述指标均有所改善(P<0.05),但G-H组明显优于G-L组(P<0.05)。HE染色及透射电镜形态学观察提示Hys组大鼠子宫平滑肌增厚,细胞边界不清晰,细胞核固缩呈椭圆形或畸形,胞质内线粒体肿胀,部分嵴断裂消失,可见粗面内质网扩张,肌纤维排列紊乱无序,可见明显炎性细胞浸润;G-L组子宫平滑肌细胞排列较Hys组有序,平滑肌层仍有所增厚,炎性细胞浸润亦较Hys组组减少,细胞核较Hys组稍增大,线粒体肿胀和粗面内质网扩张减少;G-H组子宫平滑肌细胞排列较Hys组明显有序、紧密,仅见轻微炎性细胞浸润,平滑肌层无明显增生,且平滑肌细胞核较正常,线粒体及粗面内质网形态接近正常。结论:桂枝茯苓丸有效改善子宫肌瘤模型大鼠的形态学指标,其机制可能与激活PI3K/AKT通路,下调E2、P、ER的表达,上调Caspase-3的表达有关。

取卵日血清脑源性神经营养因子与辅助生育结局的相关性

目的:探讨取卵日血中脑源性神经营养因子(BDNF)能否预测卵母细胞质量和其后的卵胞质内单精子注射(ICSI)的妊娠结局。方法:总共纳入57例进行ICSI患者,在取卵日清晨抽取空腹静脉血,测量BDNF,E2和P的浓度。比较妊娠组与非妊娠组的相关数据,并分析取卵日BDNF水平与E2、P、年龄和IVF相关数据之间的相关性。结果:妊娠组与非妊娠组的BNDF浓度无明显差异;取卵日BDNF浓度与E2和P呈明显正相关。BDNF与获卵数和成熟卵母细胞数成正相关。结论:尚不能用取卵日BDNF来预测ICSI的妊娠结局,但BDNF可能在卵母细胞发育成熟过程中发挥着重要作用。
