RESUMO
Epimedii folium is a commonly used Traditional Chinese Medicine (TCM) for warming the kidney and strengthening the yang qi. It has androgen-estrogen-like effect. It can not only directly act on sexual organs to regulate hormone levels, but also exert sex-hormone-like effect through hypothalamus-pituitary-gonadal axis. Its regulation of hormone levels is similar to that of plant hormones. At present, Epimedii folium is commonly used with other TCMs to treat diseases caused by sex-hormone deficiency, such as male spermatopenia, asthenospermia, benign prostatic hyperplasia, functional erectile dysfunction, female premature ovarian failure, perimenopausal syndrome, dysfunctional infertility during ovulation, hyperandrogenemia of PCOS patients, etc.
RESUMO
Self-injury has become a significant public health problem, especially happens in adolescents. Previous studies have suggested that self-injury is related to numerous factors. At present, the occurrence mechanism of self-injury is still unclear, and there is a lack of reliable biological markers in its diagnosis and therapeutic target so far. Previous studies have suggested that self-injury may be related to hypothalamic pituitary adrenal(HPA) axis, β-endorphins, opioids and other hormones. Hypothalamic pituitary thyroid(HPT) axis and hypothalamic pituitary gonadal(HPG) axis are endocrine systems connecting nerves and hormones. Many studies suggested that various hormones in HPT axis and HPG axis of self-injury patients with other mental disorders (such as major depression and bipolar disorder) were abnormal. At present, there are few studies on the relationship between self-injury and HPT axis and HPG axis. There are differences in results even among studies on the same hormones, and some studies involve suicide attempts and even behaviors. Some studies have confirmed that self-injury is related to suicide, expanding the possibility of exploring the correlation between self-injury and hormones. This study will review the relationship between self-injury and hormonal changes.
RESUMO
ObjectiveTo explain the scientific connotation of Morindae Officinalis Radix （MOR） processed by Glycyrrhizae Radix et Rhizoma （Gly） by comparing the effect of raw products of MOR and processed products of MOR with different proportions of Gly （GMOs） on the improvement of renal function and hypothalamic-pituitary-gonadal （HPG） axis， the protein expression of Wnt/β-catenin and transforming growth factor-β1 （TGF-β1）/Smad signal pathways in kidney Yang deficiency model rats induced by adenine. MethodGMOs were prepared according to method under MOR in 2020 edition of Chinese Pharmacopoeia. Rat model of kidney Yang deficiency was established by intragastrical administration of adenine， levels of follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E2） and testosterone （T） were measured by enzyme-linked immunosorbent assay （ELISA）. Levels of urea nitrogen （BUN） and serum creatinine （SCr） were measured by spectrophotometry， hematoxylin-eosin （HE） staining was used to evaluate the pathological changes of kidney， testis and epididymis. Immunohistochemistry （IHC） was used to analyze the protein expression of E-cadherin， α-smooth muscle actin （α-SMA）， Wnt2b， β-catenin， Smad1 and Smad4. ResultMOR processed with 100∶6 and 100∶12 proportions of Gly （short for GMO/100∶6 and GMO/100∶12） had the most obvious improvement on the body posture of kidney Yang deficiency model rats. GMO/100∶12 had the best effect on reducing the levels of BUN， SCr， FSH， LH and the ratio of E2/T. GMO/100∶6 and GMO/100∶12 had the best effect on regulating the protein expression of E-cadherin， α-SMA， Wnt2b， β-catenin， Smad1 and Smad4. ConclusionGMO/100∶6 and GMO/100∶12 have the a good effect on the improvement of renal function and HPG axis in kidney Yang deficiency model rats induced by adenine， which is related with the fact that they can regulate Wnt/β-catenin pathway in renal and testicular tissue and TGF-β1/Smads pathway in testicular tissue.

RESUMO
Background: Hypothyroidism can cause menstrual disturbances mainly oligoanovualtory cycles and sometimes menorrhagia. It has also been seen to cause subfertility and pregnancy related complications. Various studies have been done to evaluate gonadal dysfunctions in overt hypothyroidism but very few studies are there which have done using a gonadotrophin response in that subset of patients. Present study evaluates the response of leuprolide on gonadal functions of women with overt hypothyroidism in a tertiary care centre at Meerut.Methods: In this study 50 females of age 20 to 40 years with newly diagnosed overt hypothyroidism were taken as cases and age and Body Mass Index (BMI) matched healthy females were taken as controls. Both in cases and controls, basal FSH, LH, estradiol was measured on 2nd day to 5th day of menstrual cycle. Thereafter Leuprolide 20 mcg/kg was given subcutaneously on the same day. Post leuprolide test, stimulated LH, FSH and estradiol were measured. Basal and stimulated values were compared between both groups.Results: Basal LH was significantly higher in controls (8.2±3.2 mIU/L) when compared to cases (6.45±2.75 mIU/L) with a p value 0.03(<0.05). Basal estradiol and FSH levels were found to be nearly similar and non-significant in cases and controls. No significant differences were found between stimulated mean LH and estradiol in both the groups. Leuprolide response after stimulation test was found to be sluggish in patients with overt hypothyroidism compared to normal euthyroid controls. This study is the rare one done on human subject in tertiary care centre of India, however large sample and multicentric trials are necessary before establishing the biochemical results.Conclusions: Pituitary and gonadal (ovarian) response to leuprolide was found to have impaired (decreased) in overt hypothyroidism cases. This is the first study to be done in overt hypothyroid subjects to asses both basal and stimulated gonadotropin levels.
RESUMO
Objective::To explore the regulatory effect of Longmu Guizhi decoction and its decomposed formula on the hypothalamic-pituitary-adrenal axis of spontsneously hyoertensive rats (SHR) with attention deficit hyperactivity disorder (ADHD), so as to explain the scientific connotation of compound compatibility. Method::Young male SHR rats were randomly divided into saline control group, methylphenidate hydrochloride group(2 mg·kg-1), Longmu Guizhi decoction group(30 g·kg-1), Guizhi+ Longgu Muli decoction group(21 g·kg-1), Ganmai Dazaotang group(9.24 g·kg-1) and Polygalae Radix-Acori Tatarinowii Rhizome group(4.62 g·kg-1). The corresponding drugs were intragastrically administered for 14 days. Serum adrenocorticotropic hormone (CRH), adrenocorticotropic hormone (ACTH) and corticosterone (CORT) were detected by enzyme-linked immunosorbent assay(ELISA), and mRNA expressions of glucocorticoid receptor (GR), mineralocorticoid receptor (MR), CRH in hypothalamus and GR, MR in hippocampus were detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) method. Result::Serum CORT, ACTH and CRH, GR and CRH mRNA expressions of hypothalamus, GR and MR mRNA expressions of hippocampus in methylphenidate hydrochloride group and Longmu Guizhi decoction group were significantly higher than those of saline control group (P<0.05, P<0.01). MR mRNA expression of hypothalamus in Longmu Guizhi decoction group was significantly higher than that in the saline control group (P<0.05, P<0.01), and GR expression in hippocampus was significantly higher than that in the methylphenidate hydrochloride group (P<0.01). The dissection study showed that the levels of serum ACTH and CRH, MR mRNA, GR and CRH mRNA of hypothalamus, GR and MR mRNA of hippocampus in Guizhi+ Longgu Muli decoction group and Ganmai Dazaotang group were significantly higher than those in saline control group (P<0.05, P<0.01). The serum CORT level of Guizhi+ Longgu Muli decoction group was higher than that of normal saline group (P<0.01). The serum ACTH level of Polygalae Radix-Acori Tatarinowii Rhizome pair was significantly higher than that in saline control group(P<0.05). Conclusion::The mechanism of Longmu Guizhi decoction in treating ADHD is related to increase of the levels of CORT, ACTH and CRH in serum and the expressions of MR, GR, CRH in hypothalamus and GR and MR in hippocampus, so as to regulate the function of HPA axis. The order of the effect degree of each decomposition group on HPA axis function from high to low was Guizhi+ Longgu Muli decoction>Ganmai Dazao decoction>Polygalae Radix-Acori Tatarinowii Rhizome pair drug.
RESUMO
The aim of this study was to determine whether testicular volume is correlated with clinical and biochemical markers of hypothalamic-pituitary-testicular (HPT) axis function. This was a cross-sectional substudy of a larger randomized controlled trial including obese men, body mass index (BMI) ≥30 kg m-2, with a total testosterone level <12 nmol l-1. Testicular volume was measured by orchidometer, testosterone by liquid chromatography/tandem mass spectrometry, and body composition by dual-energy X-ray absorptiometry. Men completed the Aging Males' Symptoms (AMS) score, International Index of Erectile Function-5 (IIEF-5), physical function, and handgrip dynamometer testing. Eighty-nine men participated with a median (interquartile range [IQR]) age of 53.1 (47.6, 59.2) years, BMI of 37.0 (34.6, 40.5) kg m-2, and a total testosterone of 7.0 (6.1, 7.9) nmol l-1. Median testicular volume was 18 (IQR: 10, 20) ml. Testicular volume was negatively correlated with BMI (τ =-0.1952, P = 0.010) and total fat mass (τ =-0.2115, P = 0.005) independent of age and testosterone. When BMI, testosterone, sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were present in a multivariable model, only BMI (-0.38 ml change in testicular volume per 1 kg m-2BMI; 95% CI:-0.74,-0.02; P = 0.04) and LH (-0.92 ml change in testicular volume per 1 IU l-1 LH; 95% CI:-1.75,-0.095; P = 0.03) remained independent significant predictors of testicular volume. Testicular volume was positively correlated with IIEF-5 (τ = 0.2092, P = 0.021), but not related to handgrip strength, physical function tests, or AMS. In obese men, testicular volume is inversely and independently associated with measures of adiposity, but not with most clinical or biochemical markers of HPT axis action. From a clinical perspective, this suggests that obesity might compromise the reliability of reduced testicular volume as a sign of androgen deficiency in men.
RESUMO
[Objective] We assessed in a retrospective unicenter study the state of metabolism and gonadal axis of early menarche girls and girls who treated with Gonadotropin-releasing hormone analogs (GnRHa).[Methods] Thirty-nine early menarche girls and 58 girls who had been treated with GnRHa were enrolled in our study and 19 normal menarche girls were enrolled as control group.Data were collected in height,weight,gonadal hormone,blood glucose,insulin,blood lipid,leptin,adiponectin and the size of uterus and ovary.[Results] Both BMI SDS for chronological age (CA) and for bone age (BA) of early menarche girls were significantly higher than normal menarche girls (P ＜ 0.05).The ratio of insulin resistance in early menarche girls (20.5％) was also significantly higher than normal girls (0％).No significant difference in lipid metabolism and gonadal axis between two groups.In girls treated with GnRHa,BMISDS,insulin,HOMA-IR and the ratio of insulin resistance (20.7％) were all significantly higher than normal group (P ＜ 0.05).Meanwhile,DHEAS,androstenedione and testosterone of GnRHa treated girls were significantly higher than early menache girls,and DHEAS was higher than normal girls.The size of uterus in treated group was larger than the other two groups.[Conclusion] Early menarche and GnRHa treatment may take negative effect to BMI and glucose metabolism.Androgen was higher in GnRHa treated group.Therefore,suggestion was that BMI,insulin,blood glucose and androgen should be monitored in early menarche girls and girls treated with GnRHa.
RESUMO
Kisspeptins are a group of peptide fragments encoded by the KISS1 gene in humans. They bind to kisspeptin receptors with equal efficacy. Kisspeptins and their receptors are expressed by neurons in the arcuate and anteroventral periventricular nuclei of the hypothalamus. Oestrogen mediates negative feedback of gonadotrophin-releasing hormone secretion via the arcuate nucleus. Conversely, it exerts positive feedback via the anteroventral periventricular nucleus. The sexual dimorphism of these nuclei accounts for the differential behaviour of the hypothalamic-pituitary-gonadal axis between genders. Kisspeptins are essential for reproductive function. Puberty is regulated by the maturation of kisspeptin neurons and by interactions between kisspeptins and leptin. Hence, kisspeptins have potential diagnostic and therapeutic applications. Kisspeptin agonists may be used to localise lesions in cases of hypothalamic-pituitary-gonadal axis dysfunction and evaluate the gonadotrophic potential of subfertile individuals. Kisspeptin antagonists may be useful as contraceptives in women, through the prevention of premature luteinisation during in vitro fertilisation, and in the treatment of sex steroid-dependent diseases and metastatic cancers.

We studied a species of Haima-the Sea Horse Hippocampus japonicus (SHHJ). After SHHJ was given to male rats orally for twenty days. The plasma concentration of testosterone,LH and FSH was assayed by RIA,and the histological change in seminal vesicles and prostate gland was observed. It has been showed that SHHJ can obviously elevate plasma level of testosterone and improve the histological change of seminal vesicles and prostate gland in castrated rats. but there was no affect in LH、FSH. SHHJ can obviously promoted the content of testosterone of plasma and can obviously enhance the weight of the normal rat's prostate gland,seminal vesicle.
