OBJECTIVE:
To explore the therapeutic effect of Bushen Yiqi Huoxue Decoction BYHD) in patients with diminished ovarian reserve (DOR).
METHODS:
A total of 180 patients with DOR diagnosed from December 2013 to December 2014 were equally assigned into progynova and duphaston (E+D) group, Zuogui Pill group and BYHD group with 60 cases in each by computerized randomization. Patients received E+D, Zuogui Pill or BYHD for 12 months, respectively. Follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), anti-Müllerian hormone (AMH), antral follicle count (AFC), ovarian volume, endometrial thickness, and the resistance indices (RIs) of ovarian arteries and uterine arteries were observed before and after treatment.
RESULTS:
Nine women (4 from the E+D group, 3 from the Zuogui Pill group, and 2 from the BYHD group) withdrew from the study. After 6 months, Zuogui Pill and BYHD significantly decreased FSH and LH and increased endometrial thickness and AMH (all P<0.01). BYHD also resulted in E2 elevation (P<0.05), ovary enlargement (P<0.05), AFC increase (P<0.01), and RI of ovarian arteries decrease (P<0.05). After 12 months, further improvements were observed in the Zuogui Pill and BYHD groups (all P<0.01), but BYHD showed better outcomes, with lower FSH, larger ovaries and a thicker endometrium compared with the Zuogui Pill group (all P<0.01). However, E+D only significantly increased endometrial thickness (P<0.01) and no significant improvements were observed in the RI of uterine arteries in the three groups.
CONCLUSIONS
BYHD had a favorable therapeutic effect in patients with DOR by rebalancing hormone levels, promoting ovulation, and repairing the thin endometrium. The combination of tonifying Shen (Kidney), benefiting qi and activating blood circulation may be a promising therapeutic strategy for DOR.

The LH and FSH responses to synthetic LH-RH and the prolactin response to synthetic T-RH were evaluated during different phases of the mentrual cycle in order to understand secretory capacity of the pituitary during the menstrual cycle. Eleven regularly menstruating women between 22 and 35 years of age with a usual cycle length of 27 to 31 days volunteered for this Study. Volunteers received an intra-venous injection of 100 microgram synthetic LH-RH and 200 microgram synthetic T-RH during the early and the late follicular phases and during the early and midluteal phases of the menstrual cycle. LH-RH induced a prompt increase in circulating LH, reaching the peak concentration at 30 minutes following LH-RH administration in all phases of the cycle studied. A change in responsiveness with greater and more sustained LH release from the early to the late follicular phases was observed. The response during the luteal phase was significantly greater than the responses in both the early and the late follicular phases. A concomitant but a much smaller FSH response was observed. T-RH elicited a prompt increase in circulating prolactin within 30 minutes and decreased gradually thereafter, reaching the baseline level by 2 hours after T-RH administration. Maximum concentration of prolactin was reached in 30 minutes following T-RH during all phases of the menstrual cycle. No variation in pituitary responsiveness to T-RH, however, was observed during different phases of the menstrual cycle. These data indicate that the sensitivity of the pituitary gonadotrophs to LH-RH varies during different phases of the menstrual cycle.

4.Value evaluation of follicle stimulating hormone and luteinizing hormone in the diagnosis of precocious puberty in girls by ROC curve analysis.
Chinese Journal of Contemporary Pediatrics 2012;14(6):441-444
OBJECTIVETo study the value of follicle stimulating hormone (FSH), luteinizing hormone (LH) and LH/FSH ratio in the diagnosis of precocious puberty in girls by ROC curve analysis.
METHODSGonadotropin-releasing hormone (GnRH) stimulation test was performed on 220 girls with pseudo-sexual precocity and 61 girls with true sexual precocity. Blood LH and FSH levels were measured before and after 30 and 60 minutes of taking the GnRH test. The ratio of LH to FSH was calculated. Sensitivity and best point for the diagnosis of precocity according to LH, FSH and LH/FSH ratio were analyzed by ROC curve analysis.
RESULTSThe area under the ROC curve was 0.90 and 0.95 according to LH level and LH/FSH ratio respectively for the diagnosis of precocity. The best point for diagnosis by LH was 10.15 IU/L, with a sensitivity of 0.92 and specificity of 0.89. The best point for diagnosis by LH/FSH ratio was 0.60, with a missed diagnosis rate of 6.0% and specificity of 0.91. When true sexual precocity was diagnosed based on one index between LH>10.15 IU/L and LH/FSH ratio>0.60, sensitivity was 0.97 and specificity was 0.94. When the diagnosis of true sexual precocity was diagnosed based on both LH>10.15 IU/L and LH/FSH>0.60, sensitivity was 0.85 and specificity was 1.00.
CONCLUSIONSTrue sexual precocity can be diagnosed when both LH>10.15 IU/L and LH/FSH ratio>0.60. Only one of the two indexes for the diagnosis of true sexual precocity is presented, further observation is necessary to decrease missed diagnosis and misdiagnosis.

OBJECTIVETo evaluate the androgenic and anti-androgenic effects of GH (growth hormone) transgenic carp in male rats.
METHODSHershberger assay was carried out in castrated male SD rats aged 4-5 weeks. Testosterone propionate (TP) (0.4 mg/kg BW) was administrated for a positive control, GH transgenic carp (3.0 g/kg BW)+TP (0.4 mg/kg BW), parental carp (3.0 g/kg BW) + TP (0.4 mg/kg BW), and flutamide (Flu) (3.0 g/kg BW) were used for negative controls, and vehicle was administered orally for a blank control. All groups were administrated for 10 consecutive days. At the end of the test, animals were anesthetized, then weights of accessory sex organ were measured. Serum testosterone (T), luteinizing hormone (LH), and Follicle-Stimulating Hormone (FSH) levels were detected.
RESULTSThe weights ratios of the accessory sex organs and body weights showed no significant differences between the solvent control and the GH transgenic carp-treated groups. Serum concentrations of FSH, LH, and T of the rats treated with GH transgenic carp + TP showed no significant changes, compared with those treated with TP only.
CONCLUSIONGH transgenic carp does not have any androgenic agonist or antagonist properties in vivo screening tests.

OBJECTIVETo investigate the expression of 17 beta-hydroxysteroid dehydrogenase type 1 (17β-HSD1) in the kidney of rats and explore the capacity of the kidney for synthesizing sex hormones.
METHODSThe expressions of 17-HSD1 and sex hormones were detected by Western blotting and radioimmunoassay in rat renal cells in primary cultured for 24 and 48 h in the presence or absence of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
RESULTSAfter cell culture for 24 h, the primary rat renal cells expressed a low level of 17β-HSD1 (0.1843±0.076), which increased to 1.6651±0.044 (P<0.01) in response to co-stimulation by FSH and LH. Low levels of estradiol, progesterone and testosterone were also detected in rat renal cells (3.30±3.78, 62.60±12.33, and 22.12±3.36, respectively), and co-stimulation of FSH and LH significantly increased their levels to 8.50±2.64, 117.80±9.79, and 45.04±4.39, respectively (P<0.05). The levels of these hormones showed no significant differences between cells cultured for 24 h and 48 h (P>0.05).
CONCLUSIONThe rat renal cells express 17β-HSD1 and are capable of stably secreting sex hormones in response to co-stimulation with FSH and LH, suggesting the capacity of the rat kidneys for synthesizing sex hormones. These findings enrich the understanding of the endocrine function of the kidney.

In our previous study, we demonstrated that immobilization stress blocked estrogen-induced luteinizing hormone(LH) surge possibly by inhibiting the synthesis and release of gonadotropin-releasing hormone (GnRH) at the hypothalamic level and by blocking estrogen-induced prolactin (PRL) surge by increasing the synthesis of dopamine receptor at the pituitary level in ovariectomized rats. The present study was performed to determine whether immobilization stress affects pituitary LH responsiveness to GnRH, and whether endogenous opioid peptide (EOP) and dopamine systems are involved in blocking LH and PRL surges during immobilization stress. Immobilization stress was found to inhibit basal LH release and to completely abolish LH surge. However, the intravenous application of GnRH agonist completely restored immobilization-blocked LH surge and basal LH release. Treatment with naloxone did not exert any effect on immobilization-blocked LH surge but increased basal LH release during immobilization stress. Pimozide did not affect immobilization-blocked LH surge or basal LH release. Naloxone also decreased immobilization-induced basal PRL release, but had no effect on immobilization-blocked PRL surge. Immobilization-increased basal PRL levels were augmented by pimozide treatment and immobilization-blocked PRL surge was dramatically restored by pimozide. We conclude that immobilization stress does not impair pituitary LH response to GnRH, and that the immobilization stress-induced blockage of LH surge is probably not mediated by either the opioidergic or the dopaminergic system. However, immobilization-blockade of PRL surge may be partly mediated by the dopaminergic system.

AIMTo investigate the effect of arsenic on spermatogenesis.
METHODSMature (4 months old) Wistar rats were intraperitoneally administered sodium arsenite at doses of 4, 5 or 6 mg.kg(-1).day(-1) for 26 days. Different varieties of germ cells at stage VII seminiferous epithelium cycle, namely, type A spermatogonia (ASg), preleptotene spermatocytes (pLSc), midpachytene spermatocytes (mPSc) and step 7 spermatids (7Sd) were quantitatively evaluated, along with radioimmunoassay of plasma follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone and assessment of the epididymal sperm count.
RESULTSIn the 5 and 6 mg/kg groups, there were significant dose-dependent decreases in the accessory sex organ weights, epididymal sperm count and plasma concentrations of LH, FSH and testosterone with massive degeneration of all the germ cells at stage VII. The changes were insignificant in the 4 mg/kg group.
CONCLUSIONArsenite has a suppressive influence on spermatogenesis and gonadotrophin and testosterone release in rats.

BACKGROUNDDelayed puberty can result either from constitutional delay of growth and puberty (CDP) or idiopathic hypogonadotropic hypogonadism (IHH). Gonadotropin-releasing hormone (GnRH) stimulation test has been generally accepted as a current method for diagnosing delayed puberty. The objective of this research was to assess the cut-off values and the efficacy of GnRH stimulation test in the diagnosis of delayed puberty in both males and females.
METHODSA study of 91 IHH, 27 CDP patients, 6 prepubertal children, and 20 pubertal adults was undertaken. Blood samples were obtained at 0, 30, 60, and 120 min after GnRH administration and the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured. For each parameter, the sensitivities and specificities were estimated, and the receiver operating characteristic (ROC) curves were constructed.
RESULTSThe ROC curves indicated that a serum basal LH <0.6 IU/L or peak LH <9.74 IU/L resulted in moderate sensitivity (73.8% or 80.0%) and specificity (90.9% or 86.4%) in the diagnosis of HH in males. Serum basal LH <0.85 IU/L or basal FSH <2.43 IU/L resulted in moderate sensitivity (80.0% or 100.0%) and specificity (75.0% or 50.0%) in the diagnosis of HH in females.
CONCLUSIONSOur data suggest that isolated use of the gonadorelin stimulation test is almost sufficient to discriminate between HH and CDP in males, but unnecessary in females. The most useful predictor is serum basal or peak LH to differentiate these two disorders in males, but serum basal LH or FSH in females.

OBJECTIVETo observe the effect of nourishing yin removing fire Chinese herbs (NYRF-CH) on the gene expression of hypothalamic growth hormone secretion peptide (Ghrelin) and its receptor growth hormone secretion peptide receptor 1alpha (GHSR1-alpha) at the puberty onset of danazol induced female precocious rats.
METHODSForty female SD rats were randomly divided into 4 groups, i.e., the normal group (N), the model group (M), the normal saline intervention group (NS), and the NYRFCH intervention group (NI), 10 in each group. 300 microg danazol was subcutaneously injected to all rats except those in the N group to prepare precocious rat model. NYRFCH and normal saline was respectively administered to rats in the NI and the NS group from the 15th day old for 7-10 days. No treatment was given to rats in the N group. Time of rats' vulva opening was recorded. Ovary index and uterus index were calculated. Peripheral blood levels of estradiol (E2), follicle stimulating hormone (FSH), and luteinizing hormone (LH), and hypothalamic contents of gonadotropin releasing hormone (GnRH) as well as the gene expression of hypothalamic Ghrelin and GHSR1-alpha were determined. Results Compared with the N group, the vulva opening time was advanced in the model group; peripheral blood levels of E2 and LH, uterus index, hypothalamic contents of GnRH increased; peripheral blood FSH levels and mRNA levels of hypothalamic Ghrelin and GHSR1-alpha decreased (P < 0.05, P < 0.01). Compared with the M group and the NS group, the vulva opening time was not advanced in the NI group; peripheral blood levels of E2 and LH, uterus index and hypothalamic contents of GnRH obviously decreased (P < 0.05, P < 0.01); mRNA levels of hypothalamic Ghrelin and GHSR1-alpha increased (all P < 0.01). But there was no statistical difference in the hypothalamic contents of Ghrelin, or the number and activity of GHSR1-alpha (P > 0.05).
CONCLUSIONNYRFCH had regulatory effect on regulating hypothalamic Ghrelin and GHSR1-alpha at gene transcription levels.
