Many modifiable lifestyle risk factors increase the risk of women to several reproductive disorders. Aim: This study established the relationship between obesity and Hypothalamic-Pituitary-Ovarian (HPO) axis hormones in infertile women in the Niger Delta Region, Nigeria. Methodology: Six hundred and twenty-six (626) women aged 18 - 40 years comprising of 513 obese infertile women and 113 non obese women who served as control were recruited for the study. Anthropometric measurements were taken and Body Mass Index was calculated. A non-fasting venous blood sample was collected from the women and analyzed for serum Estrogen, Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Progesterone, Inhibin B, and Prolactin using Enzyme linked immunosorbent assay method. Results: In the present study, the Body Mass Index of women with primary (1°) infertility is significantly (p < 0.05) higher than secondary (2°) infertility women. Whereas, women with 2° infertility were older and have a higher height than women with 1° infertility. The result revealed that serum estrogen, luteinizing hormone, follicle stimulating hormone and prolactin levels were significantly (p < 0.05) higher in the obese infertile women, while inhibin B and progesterone levels were significantly (p < 0.05) reduced in the obese infertile women compared to the control subjects. However, women with 1° infertility have a significantly higher LH and FSH levels than the 2° infertility women. Furthermore, the study revealed that hyperestrogenism is the most prevalent gonadal disorder in women with primary infertility and secondary infertility. The BMI of infertile women suffering Hyperestrogenism is significantly higher than any other female gonadal disorder. The result also showed that there is statistically significant positive correlation between BMI and Hypogonadism, Hypogonadotropic and Amenorrhoea in obese infertility women. While, no significant correlation between BMI and Hypergonadism and Hypergonadotropic was observed. Furthermore, there was a positive correlation between BMI and Hypothalamus-Pituitary Ovarian hormones, as BMI showed a positive correlation with LH, FSH, Estrogen, progesterone, and prolactin in women with primary and secondary infertility, while Inhibin B showed a negative correlation with BMI. Conclusion: There is a relationship between BMI and Hypothalamus-Pituitary Ovarian hormones, signifying that obesity could affect female reproduction and directly impact ovarian function. Therefore, body weight maintenance should be considered as a first line of management of Hypothalamus-Pituitary Ovarian hormonal related infertility.展开更多

Methods: Patients who underwent knee replacement in People's Hospital of Dongxihu District between April 2015 and January 2018 were selected as the research subjects and randomly divided into the experimental group who accepted flurbiprofen axetil combined with patient-controlled intravenous analgesia and the control group who accepted patient-controlled intravenous analgesia alone. The contents of cytokines and HPA axis-related hormones in serum were measured before surgery as well as 1 d and 3 d after surgery;the contents of cytokines in joint fluid were measured 1 d and 3 d after surgery. Results: Compared with those of same group before surgery, NGF, NPY, TNF-α, IL-2, IL-4, IL-10, ACTH, COR, INS, GH and PRL levels of both groups were increasing 1 d and 3 d after surgery, and NGF, NPY, TNF-α, IL-2, IL-4, IL-10, ACTH, COR, INS, GH and PRL levels in serum as well as PGE2, OPN, TGF-β1, FGF21, CXCL12 and YKL-40 in joint fluid of experimental group 1 d and 3 d after surgery were lower than those of control group. Conclusion: Flurbiprofen axetil analgesia after knee replacement can reduce the release of cytokines in serum and joint fluid, and inhibit the activity of HPA axis, and its analgesic effect is exact.展开更多

Wistar albino rats of either sex weighing 180-220 g （n = 6） were employed. Diabetes was induced by administering STZ （streptozotocin） （45 mg/kg, i.p.） once. Neuropathy was induced by the ligation of sciatic nerve in diabetic animals. A glucocorticoid receptor antagonist： ketoconazole 175 mg/kg, p.o. and glucocorticoid receptor agonist： hydrocortisone 1 mg/kg, i.p. were given. Assessment of neuropathic pain was achieved using hot plate and hot immersion tests. Tissue biochemical： lipid peroxidation, NO and glutathione were estimated on 28th day spectrophotometrically. Plasma cortisol level was also estimated using HPLC （high performance liquid chromatography）. Sciatic nerve ligation to diabetic animals caused significant increase in nociceptive responses as hyperalgesia and allodynia, tissue lipid peroxidation and NO products, and decrease in GSH （glutathione） level, in comparison to SC （saline control）. Ketoconazole administration produced decreased pain responses as well as decrease in oxidative stress and inflammatory mediators. Administration of hydrocortisone resulted in suppression of HPA axis. The activation of HPA axis in diabetic animals resulted in significant pain response. This may be due to increased corticosterone level which in turn desensitizes HPA axis and decreased nociceptive response in diabetic animals observed.展开更多

Hyperactivity of the hypothalamic-pituitary-adrenal （HPA） axis is one of the most consistent biological findings in anxiety- and depression-related disorders. The HPA axis is reported to be susceptible to developmental reprogramming. The present study focused on HPA reactivity in postnatal day （PND） 80 male rats exposed perinatally to environmental-dose BPA. When female breeders were orally administered 2 μg/（kg.day） BPA from gestation day 10 to lactation day 7, their offspring （PND 80 BPA-exposed rats） showed obvious anxiety/depression-like behaviors. Notably, significant increase in serum corticosterone and adrenocorticotropin, and corticotropin-releasing hormone mRNA were detected in BPA-exposed rats before or after the mild stressor. Additionally, the level of glucocorticoid receptor mRNA in the hippocampus, but not the hypothalamus, was decreased in BPA-exposed rats. The levels of hippocampal mineralocorticoid receptor mRNA, neuronal nitric oxide synthase and phosphorylated cAMP response element binding protein were increased in BPA-exposed rats. In addition, the testosterone level was in BPA-exposed rats. The results indicate that reprogramming-induced hyperactivity of the HPA axis is an important link between perinatal BPA exposure and persistent potentiation in anxiety and depression.展开更多
