Gongning granules plus low dose hormone in pubertal functional uterine hemorrhage: Analysis of hemodynamics and clinical efficacy.

To evaluate the clinical effect of Gongning granules combined with low-dose hormone therapy in pubertal dysfunctional uterine bleeding (PDUB) and its effect on uterine hemodynamics. A total of 164 PDUB patients who were treated in the gynecological outpatient department of our hospital from December 2018 to June 2020 were randomized into study group and control group, with 82 cases each. The control group received estrogen progesterone, and the study group received Gongning granules plus. The clinical efficacy and uterine arterial hemodynamics were compared. The clinical efficacy of the study group was superior to the control group (91.46% vs. 76.83%, P<0.05). The study group yielded shorter bleeding control time and complete hemostasis time than the control group (P<0.05). The amount of menstrual bleeding and duration of menstruation in both groups decreased significantly with time and the study group was significantly lower than the control group (all P<0.05). The endometrial thickness in the study group was significantly thinner than the control group, and the maximum follicle diameter was significantly longer than that in the control group (all P<0.05). After treatment, the platelet count, hemoglobin level of peripheral blood, uterine arterial blood flow and mean flow velocity in the study group were significantly higher than those in the control group (all P<0.05). In addition, there was no significant difference in adverse drug reaction (ADR) between the two groups (P>0.05). In PDUB patients, Gongning granules plus low-dose hormone can significantly relieve bleeding symptoms, improve hemodynamic status and has good safety.

Cytokines, Hormones and Cellular Regulatory Mechanisms Favoring Successful Reproduction.

Its semi-allogeneic nature renders the conceptus vulnerable to attack by the maternal immune system. Several protective mechanisms operate during gestation to correct the harmful effects of anti-fetal immunity and to support a healthy pregnancy outcome. Pregnancy is characterized by gross alterations in endocrine functions. Progesterone is indispensable for pregnancy and humans, and it affects immune functions both directly and via mediators. The progesterone-induced mediator - PIBF - acts in favor of Th2-type immunity, by increasing Th2 type cytokines production. Except for implantation and parturition, pregnancy is characterized by a Th2-dominant cytokine pattern. Progesterone and the orally-administered progestogen dydrogesterone upregulate the production of Th2-type cytokines and suppress the production of Th1 and Th17 cytokine production in vitro. This is particularly relevant to the fact that the Th1-type cytokines TNF-α and IFN-γ and the Th17 cytokine IL-17 have embryotoxic and anti-trophoblast activities. These cytokine-modulating effects and the PIBF-inducing capabilities of dydrogesterone may contribute to the demonstrated beneficial effects of dydrogesterone in recurrent spontaneous miscarriage and threatened miscarriage. IL-17 and IL-22 produced by T helper cells are involved in allograft rejection, and therefore could account for the rejection of paternal HLA-C-expressing trophoblast. Th17 cells (producing IL-17 and IL-22) and Th22 cells (producing IL-22) exhibit plasticity and could produce IL-22 and IL-17 in association with Th2-type cytokines or with Th1-type cytokines. IL-17 and IL-22 producing Th cells are not harmful for the conceptus, if they also produce IL-4. Another important protective mechanism is connected with the expansion and action of regulatory T cells, which play a major role in the induction of tolerance both in pregnant women and in tumour-bearing patients. Clonally-expanded Treg cells increase at the feto-maternal interface and in tumour-infiltrating regions. While in cancer patients, clonally-expanded Treg cells are present in peripheral blood, they are scarce in pregnancy blood, suggesting that fetal antigen-specific tolerance is restricted to the foeto-maternal interface. The significance of Treg cells in maintaining a normal materno-foetal interaction is underlined by the fact that miscarriage is characterized by a decreased number of total effector Treg cells, and the number of clonally-expanded effector Treg cells is markedly reduced in preeclampsia. In this review we present an overview of the above mechanisms, attempt to show how they are connected, how they operate during normal gestation and how their failure might lead to pregnancy pathologies.

Early-Pregnancy Dydrogesterone Supplementation Mimicking Luteal-Phase Support in ART Patients Did Not Provoke Major Reproductive Disorders in Pregnant Mice and Their Progeny.

Progestogens are frequently administered during early pregnancy to patients undergoing assisted reproductive techniques (ART) to overcome progesterone deficits following ART procedures. Orally administered dydrogesterone (DG) shows equal efficacy to other progestogens with a higher level of patient compliance. However, potential harmful effects of DG on critical pregnancy processes and on the health of the progeny are not yet completely ruled out. We treated pregnant mice with DG in the mode, duration, and doses comparable to ART patients. Subsequently, we studied DG effects on embryo implantation, placental and fetal growth, fetal-maternal circulation, fetal survival, and the uterine immune status. After birth of in utero DG-exposed progeny, we assessed their sex ratios, weight gain, and reproductive performance. Early-pregnancy DG administration did not interfere with placental and fetal development, fetal-maternal circulation, or fetal survival, and provoked only minor changes in the uterine immune compartment. DG-exposed offspring grew normally, were fertile, and showed no reproductive abnormalities with the exception of an altered spermiogram in male progeny. Notably, DG shifted the sex ratio in favor of female progeny. Even though our data may be reassuring for the use of DG in ART patients, the detrimental effects on spermatogenesis in mice warrants further investigations and may be a reason for caution for routine DG supplementation in early pregnancy.

Dydrogesterone supplementation in women with threatened preterm delivery--the impact on cytokine profile, hormone profile, and progesterone-induced blocking factor.

Progesterone is indispensable in creating a suitable endometrial environment for implantation, and also for the maintenance of pregnancy. Successful pregnancy depends on an appropriate maternal immune response to the fetus. A protein called progesterone-induced blocking factor (PIBF) acts by inducing Th2-dominant cytokine production to mediate the immunological effects of progesterone. The aim of this prospective study was to compare serum concentrations of progesterone (P), estradiol (E2), anti-inflammatory (IL-10) and pro-inflammatory (IL-6, TNFα, IFNγ) cytokines, and serum PIBF concentrations in women with threatened preterm delivery who were given progesterone supplementation (study group) with those of women with threatened preterm delivery who were not given progesterone supplementation (control group). After dydrogesterone treatment of patients in the study group, serum PIBF as well as progesterone concentrations significantly increased. Women in this group had significantly higher serum levels of IL-10 than controls. The length of gestation was significantly higher in the group of women who were given progesterone supplementation. Our data suggest that dydrogesterone treatment of women at risk of preterm delivery results in increased PIBF production and IL-10 concentrations, and lower concentrations of IFNγ.

Improvement in immediate memory after 16 weeks of tualang honey (Agro Mas) supplement in healthy postmenopausal women.

OBJECTIVE: The aim of this study was to evaluate the verbal learning and memory performance of postmenopausal women who received tualang honey (Agro Mas) in comparison with women receiving estrogen plus progestin therapy and untreated controls. METHODS: A total of 102 postmenopausal women were recruited and randomly assigned to three groups: tualang honey (20 g/d)[corrected], estrogen plus progestin therapy (Femoston 1/5), and untreated control. Their verbal learning and memory performances were assessed using the Malay version of the Auditory Verbal Learning Test before and after 16 weeks of intervention. Data were analyzed using the repeated-measures analysis of variance, and a P value of less than 0.05 was considered significant. RESULTS: There were significant differences in the mean scores of total learning as well as the mean scores of trials A1, A5, A6, and A7 between the three groups. There were also significant differences in the overall mean scores of total learning and trials A1 and A5 between both estrogen plus progestin therapy and tualang honey groups when compared with the untreated control group. However, significant differences in the mean score for trials A6 and A7 were only observed between the estrogen plus progestin therapy and untreated control groups. CONCLUSIONS: Postmenopausal women who received tualang honey showed improvement in their immediate memory but not in immediate memory after the interference and delayed recall. This is comparable with the improvement seen in women receiving estrogen plus progestin therapy.

Long-term effects of oral and transdermal hormone replacement therapy on plasma homocysteine levels.

OBJECTIVE: To compare the long-term effects of oral and transdermal hormone replacement therapy (HRT) on serum homocysteine levels in postmenopausal women. DESIGN: An open, prospective, controlled study. Seventy-five healthy postmenopausal women were recruited as eligible for the study. Fifty women seeking HRT were randomized to receive continuous 17beta-estradiol, either by oral (2 mg daily; n = 25) or transdermal (50 microg daily; n = 25) administration, plus 10 mg dydrogesterone daily for 14 days of each 28-day cycle. Twenty-five women unwilling to receive hormone treatment received only calcium supplementation, representing the control group. Fasting blood samples were analyzed at baseline and then after 6, 12, and 24 months to determine plasma homocysteine levels. RESULTS: Fifty-nine women completed the study. After 6 months of therapy, homocysteine concentrations showed a statistically significant reduction in the treated groups versus both baseline and controls, and no further significant variations were found thereafter. The mean reduction in the homocysteine levels throughout the study was 13.6% in the oral and 8.9% in the transdermal group, respectively, without significant difference between the two routes of estradiol administration. Women with the highest baseline levels of homocysteine experienced the greatest reduction. No significant variations in homocysteine concentrations were found in the control group. CONCLUSIONS: Oral and transdermal estradiol sequentially combined with dydrogesterone shows comparable effectiveness in reducing plasma homocysteine levels in postmenopausal women. Women with the highest pretreatment concentrations of homocysteine benefit the most by the lowering effect of HRT.

Beneficial effects of hormonal replacement therapy on chromium status and glucose and lipid metabolism in postmenopausal women.

OBJECTIVES: Postmenopausal women exhibit an increased incidence of cardiovascular diseases, and type 2 diabetes mellitus compared with younger women. However, women receiving hormonal replacement therapy (HRT) seem to be protected. Since chromium (Cr) functions in glucose, lipid and corticosteroid metabolism and these variables, as well as Cr status, decline with age, Cr status may be a contributing factor in the effects of hormone replacement therapy. Therefore, the objective of this study was to determine the effects of hormonal replacement therapy (HRT) on serum and urinary Cr, plasma lipids, glucose, fructosamine and the related hormonal variables, estradiol, insulin, leptin, cortisol, and DHEA-sulfate. METHODS: Forty-four healthy postmenopausal women 50-60 years old participated in the study. Eighteen were treated by combined oral hormonal replacement therapy (estradiol 2 mg per day during days 1-25 and 10 mg of dydrogesterone on days 10-25) for at least 2 years, and 26 were untreated. RESULTS: Serum Cr concentrations were significantly lower in untreated postmenopausal women than in women receiving HRT (0.070+/-0.008 vs. 0.100+/-0.008 ng/ml) whereas urinary Cr excretion was increased (0.14+/-0.02 vs. 0.07+/-0.01 ng of Cr/mg creatinine). The urinary losses of Cr were inversely correlated with plasma estradiol. Median value of urinary Cr was higher in postmenopausal women exhibiting endogenous estradiol levels below 250 pmol/l, whereas women with estradiol levels >250 pmol/l, exhibited lower Cr values. Plasma fructosamine, total and LDL cholesterol and TC/HDL ratio, which are all decreased by improved Cr nutrition, were also improved in the women receiving HRT. There were also nonsignificant decreasing trends in DHEA-sulfate (P<0.06) and cortisol (0.07). CONCLUSIONS: Chromium status, based upon blood and urinary analyses, and glucose, insulin and lipid variables were improved in postmenopausal women receiving HRT. Additional studies are needed to determine if improved Cr status due to supplemental Cr can elicit effects consistent with those of hormone replacement therapy.

A comparison of hormone therapy, coping skills training, and relaxation for the relief of premenstrual syndrome.

Approximately 10% of women are severely affected by premenstrual syndrome (PMS) during their reproductive years. Several biological theories of causation have been proposed and each has provoked treatment attempts through medication to little sustained effect. As many of the reported complaints are psychological, a new treatment approach was considered using cognitive-behavioral therapy. A preliminary study which combined cognitive-behavioral therapy with drug treatment produced considerable symptom reduction. The present study examined the efficacy of cognitive-behavioral therapy alone in direct comparison with hormone treatment. Relaxation instructions were provided to a control group. Initial rapid responses to drug treatment and relaxation diminishes after 2 months, together with marked attrition in the control group. Significant positive benefits from cognitive-behavioral therapy were achieved after the first treatment month that continued throughout and were maintained at follow-up 3 months later. Implications for future management are discussed.
