BACKGROUND: Many experimental and observational studies have suggested that hormone replacement therapy (HRT) in postmenopausal women is cardioprotective. However, the results of randomized controlled trials have been discouraging. We attempted to evaluate the influence of overweight, a frequent risk factor for coronary artery disease, on the lipid-modifying effects of HRT. METHODS: A total of 345 postmenopausal women were divided into 2 groups according to body mass index (BMI) : the control group; BMI < 25 Kg/m2 (n=248) and the overweight group; BMI > or=25 Kg/m2 (n=97). All women received either 0.625 mg conjugated equine estrogen (CEE) (n=139), CEE plus 5 mg medroxyprogesterone acetate (MPA) (n=97) or CEE plus 10 mg MPA (n=109). Lipid profiles were measured before and 12 months after HRT. RESULTS: In both the control and overweight groups, HRT reduced low density lipoprotein cholesterol (LDL-C) (p=0.000 and p=0.000 respectively) and lipoprotein (a) [Lp (a) ] levels (p=0.000 and p=0.000 respectively) and raised high density lipoprotein cholesterol (HDL-C) levels (p=0.000 and p=0.002 respectively). However, the elevation of the HDL-C level was higher in the control group than in overweight group (17.5% vs. 10.4%, p=0.015), and this was significant after adjusting for changes in body weights (p=0.016). There were no differences in the reduction of LDL-C (p=0.20) and Lp (a) (p=0.09) levels between the two groups. CONCLUSION: HRT had less favorable effects on HDL-C levels in overweight postmenopausal women than in women with normal body weight. This finding may be partially associated with no cardioprotective effect of HRT in postmenopausal patients at a high risk due to multiple risk factors including obesity.

OBJECTIVETo study the therapeutic effects of Rhizoma Drynariae and estrogen on osteoporosis in ovariectomized (OVX) rats.

METHODSFifty-five female rats were randomly divided into 5 groups, the normal control (normal),the sham operated (sham), the model, the estrogen, and the Rhizoma drynariae (RD) groups; ovariectomized rats were used as postmenopausal osteoporosis model. The changes of morphology and dynamic parameters in different groups were determined by bone histomorphometry.

RESULTSCompared with the model group, the trabecular volume (TBV/TTV) , trabecular thickness (MTPT) and density (MTPD) in the other four groups were significantly increased, while the trabecular template spacing (MTPS) and the ratio of trabecular surface to trabecular volume (TBS/TBV) significantly decreased (P <0. 05); and the osteoid surface (TOS), single label surface [Sfract (s) ] ,double label surface [Sfract (d) ] and bone formation rate (Svf) also decreased,while osteoid maturation period (OMP) increased in the latter four groups. No significant difference of cortical width (MCW) was found between these 5 groups. Compared with the normal and sham groups, TOS, Sfract ( s) , Sfract ( d) , Svf in the estrogen and RD groups increased significantly, while OMP decreased; no significant difference was found in other parameters.

CONCLUSIONRhizoma Drynariae has the similar effect with estrogen in maintaining normal trabecular structure and connection by inhibiting the increased bone turnover of postmenopausal osteoporosis.

OBJECTIVES: Hysteroscopic adhesiolysis (HA) remains the mainstay on treatment for intrauterine adhesions (IUA). The fertility outcome of patients with moderate and severe intrauterine adhesions after HA is still far from satisfactory. Estrogen combined with progesterone is the most common treatment; however, they do not help in improving the fertility rate to the maximum because of the limitations. This retrospective, non-randomized controlled study will assess the effects of traditional Chinese medicine Yangmo decoction after HA in restoration of the endometrium and improvement of the fertility rate. METHODS: A total of 427 patients, who met the inclusion criteria, aged between 20 and 45 years and diagnosed with moderate or severe IUA underwent HA at the Third Xiangya Hospital from January to August 2021, were enrolled for this study. Participants were assigned into 2 groups: A Yangmo decoction group (n=213, patients were given Yangmo decoction consisting of Ginseng flower, Sanchi flower, Daidai flower, Snow lotus, Licorice and so on after HA), and an estrogen and progesterone group (n=214, patients were given estrogen and progesterone after HA). The following basic information was collected retrospectively for both groups, including age, parity, history of abortion, menstrual status, and times of hysteroscopic interventions. American Fertility Society (AFS) score was used by a senior surgeon and the density of opening of endometrial glands was evaluated during HA. The parameters were obtained from three-dimensional transvaginal ultrasound (3D-TVUS) preoperatively and postoperatively, to evaluate the efficacy of Yangmo decoction, estrogen, and progesterone. All patients were followed up on telephone to determine the fertility rate until 6 months from the last HA. RESULTS: Based on the basic information collected preoperatively, there were no significant differences between the groups (all P>0.05). Postoperatively, patients in the Yangmo decoction group had a better surgical success rate with a more significant AFS reduction (P<0.001), better density of opening of endometrial glands in the uterine cavity (P<0.000 1) after HA, and a better fertility rate (40.4%) in the time of 6 months after the last HA than those of the estrogen and progesterone group. CONCLUSIONS Yangmo decoction has better therapeutic efficacy in the treatment of intrauterine adhesion after HA than the combined effect of estrogen and progesterone. Yangmo decoction helps restore the endometrium and improve the fertility rate, therefore, it can be adopted as a routine practice for IUA patients who have fertility requirements.

OBJECTIVETo observe the clinical efficacy of bushen huoxue recipe (BHR) combined estrogen and progesterone in treating premature ovarian failure (POF), and to explore an effective treatment program of POF by integrative medicine.

METHODSTotally 265 POF patients were randomly assigned to 3 groups, i.e., Group I (86 cases, treated by BHR),Group II (88 cases,treated by conjugated estrogens and medroxyprogesterone acetate), and Group III (91 cases,treated by BHR +conjugated estrogens and medroxyprogesterone acetate). The therapeutic course for each group was 6 months. The main symptoms (including menstrual cycle, hectic fever, night sweat, vaginal dryness, and low libido), laboratory indices [including follicle stimulating hormone (FSH), luteotropic hormone (LH), estradiol (E2), and inhibin B (INH-B)], B-ultrasound indicators (including endometrial thickness, ovarian volume, and antral follicle count), and adverse reactions were observed in the three groups at the end of treatment and 6 months after treatment.

RESULTSCompared with before treatment, the main symptoms, laboratory indices, and B-ultrasound indicators were statistically improved in the three groups at the end of treatment and 6 months after treatment (P <0.05, P <0.01). Better effects were obtained in Group III in improving symptoms of the menstrual cycle, vaginal dryness, and low libido, lowering levels of FSH and LH, elevating levels of E2and INH-B, and ameliorating the endometrial thickness, the ovarian volume, and the antral follicle count (P <0.05, P <0.01). No obvious adverse reaction occurred in the three groups.

CONCLUSIONBHR combined estrogen and progesterone showed better clinical efficacy than use of BHR or estrogen/progesterone alone, indicating it was an effective treatment program for POF.

Aromatase is the rate-limiting enzyme in estrogen biosynthesis. The third generation aromatase inhibitors (AIs), represented by letrozoleand and anastrozole, can combine with aromatase, effectively reducing the estrogen level in the body. Because of its high efficiency, selectivity and reversibility, it has been used in the treatment of McCune-Albright syndrome, familial male-limited precocious puberty, gynecomastia, and adolescent boy with short stature. The good efficacy and safety of AIs have been observed. However, so far the drug instructions of AIs usually do not show indications for children; there are risks of adverse reactions involving liver and kidney function, lipid metabolism, hyperandrogenemia and bone metabolism; especially the long-term effects on reproductive system and bone metabolism are still not clear. Therefore, it is necessary to prescribe it carefully and follow up closely. It was not recommended that AIs be routinely used to improve adult height of adolescent boy with short stature. And more clinical evidences are needed for the safety and effectiveness of AIs prescribed in pediatrics.

Postmenopausal osteoporosis is a kind of degenerative disease, also described as "invisible killer." Estrogen is generally considered as the key hormone for women to maintain bone mineral content during their lives. Iron accumulation refers to a state of human serum ferritin that is higher than the normal value but less than 1000 μg/L. It has been found that iron accumulation and osteoporosis could occur simultaneously with the decrease in estrogen level after menopause. In recent years, many studies indicated that iron accumulation plays a vital role in postmenopausal osteoporosis, and a significant correlation has been found between iron accumulation and fragility fractures. In this review, we summarize and analyze the relevant literature including randomized controlled trials, systematic reviews, and meta-analyses between January 1996 and July 2022. We investigate the mechanism of the effect of iron accumulation on bone metabolism and discuss the relationship of iron accumulation, osteoporosis, and postmenopausal fragility fractures, as well as the main clinical treatment strategies. We conclude that it is necessary to pay attention to the phenomenon of iron accumulation in postmenopausal women with osteoporosis and explore the in-depth mechanism of abnormal bone metabolism caused by iron accumulation, in order to facilitate the discovery of effective therapeutic targets for postmenopausal osteoporosis.

Osteoporosis is one of the most serious complications of corticosteroid treatment. Loss of bone mineral density (BMD) and fractures occur early in the course of corticosteroid treatment, and thus early recognition of fracture risk and effective intervention based on evidence-based-medicine (EBM) are needed. A study of meta-analysis representing the highest level in a hierarchy of evidence showed that when the outcome measure of interest was limited to changes in lumbar spine BMD, bisphosphonates were the most effective of the agents studied in comparison with no therapy or treatment with calcium, and were also more efficacious than either vitamin D or calcitonin; the efficacy of bisphosphonates was enhanced when used in combination with vitamin D. Randomized controlled trials (RCTs) representing the second level in a hierarchy of evidence showed that bisphosphonates stabilized BMD not only in the lumbar spine, but also in the hip, and that parathyroid hormone (PTH) markedly increased lumbar spine BMD. According to the EBM, bisphosphonates and possibly PTH are suggested to be the most efficacious for preserving BMD. The efficacy of these agents in reducing the incidence of vertebral fractures in patients exposed to corticosteroids remains to be established in meta-analysis studies, although some RCTs have demonstrated the anti-fracture effects of etidronate, alendronate, and risedronate in the spine. Further RCTs of fracture prevention conducted on a large number of patients and their meta-analysis are needed to confirm the efficacy of bisphosphonates, PTH, or other agents in preventing vertebral and nonvertebral fractures.

OBJECTIVETo explore the effect of Yijing Huoxue Cuyun Decoction (YHCD) in adjusting hypoestrogenemic response induced by clomiphene.

METHODSInfertile patients caused by ovulation disturbance were randomly divided into 2 groups. The 60 patients in the observed group were treated with clomiphine plus YHCD, and the 58 patients in the control group were given clomiphine plus estradiol valerate.

RESULTSBy scoring on the cervical relaxation and improvement of cervical mucus, 38 patients (63.3%) in the observed group had Insler score of more than 8 points, while that in the control group was only 25 (43.1%), comparison between the two groups showed significant difference (P < 0.05). The endometrium thickening in the observed group was 0.98 +/- 0.19 cm, significantly different to that in the control group (0.85 +/- 0.21 cm, P < 0.01). Twenty-five patients in the observed group (41.7%), and fourteen patients in the control group (24.1%), respectively got pregnancy, the pregnant rate in the former was obviously higher than that in the latter (P < 0.05).

CONCLUSIONYHCD can ameliorate hypoestrinemia induced by clomiphene and increase the pregnant rate in patients.
