- Abstract
We compared the social adjustment among Chinese children born after intracytoplasmic sperm injection (ICSI) vs those after in vitro fertilisation (IVF) and identify factors related to the adjustment. The social adaptation of 86 ICSI and 165 IVF conceived children of 4-6 years of age was assessed using the Infants-Junior Middle School Students' Social-Life Abilities Scale. There was no significant difference between the ICSI and IVF-conceived groups on the item of communication, self-dependence, locomotion, work skills, socialisation, self-management and total scores. Compared with routine IVF, ICSI does no harm to the social adaptation of children conceived through this technology. [ABSTRACT FROM AUTHOR]

di-(2-Ethylhexyl) phthalate (DEHP) has potential reproductive toxicity. Bu-Shen-Tian-Jing formulations (BSTJFs) are beneficial for female reproductive capacity. However, BSTJF2 has much lower cytotoxicity than BSTJF1. To investigate the effects of BSTJFs on ovarian granulosa cells exposed to DEHP and determine the potential molecular mechanisms. Human granulosa-like tumor cell line (KGN) cells were divided into control, DEHP, BSTJF1 and BSTJF2 groups. The DEHP group were given 1 μM DEHP for 24 h. They were then given BSTJF1 at 200 μg/mL or BSTJF2 at 100 μg/mL for 24 h. The control group was treated with the same concentration of DMSO (0.1%). Oxidative stress and mitochondrial function were measured. The mRNA and protein expression levels of HDAC3 and HSP90AA were determined. Integrative network pharmacology analysis of BSTJF2 was also performed. DEHP (1 μM) significantly suppressed the proliferation of KGN cells by 17%, significantly increased ROS levels by 28% and MDA levels by 47%, significantly decreased MMP levels by 22% and mtDNA copy by 30%. DEHP significantly increased protein expression of HDAC3 by 21%and HSP90AA by 64%. All these changes were significantly reversed by BSTJFs. Integrative network pharmacology analysis revealed HSP90AA was a key target (degree = 8). Both RGFP966 and BSTJF2 significantly reversed the increased expression of HDAC3 and HSP90AA, attenuated oxidative stress, and mitochondrial damage which were induced by DEHP. BSTJFs might have therapeutic potential on oxidative stress and mitochondrial damage through the HDAC3/HSP90AA pathway which encourages further clinical trials. [ABSTRACT FROM AUTHOR]

The present study aimed to explore the association between gestational diabetes mellitus (GDM) and Chemerin, by analysing Chemerin level, clinical data and biochemical parameters among 46 GDM patients and 43 controls. It was found that the Chemerin levels from cord blood, peripheral blood, adipose tissue and placenta tissue were all significantly higher in the GDM group than those in the control group (p < .05 for all). Maternal insulin resistance (IR) index and serum inflammation parameters, including C-reactive protein and white blood cells, were also higher in GDM group (p < .05 for all). Moreover, maternal IR index and circulating insulin level were both positively correlated with maternal circulating Chemerin level (p < .05 for both). Our findings suggest that Chemerin, associated with IR and more expressed in GDM women, might participate in the pathogenesis of GDM. Impact Statement What is already known on this subject: Chemerin, a recently-discovered adipocytokine, has been widely-considered to be involved in metabolic diseases, and several studies have investigated it in gestational diabetes mellitus (GDM), but with no consensus about the level comparison between GDM and controls. What the results of this study add: The present case-control study found that the levels of Chemerin from cord blood, peripheral blood, adipose tissue and placenta tissue were all significantly higher in the GDM group. What the implications are of these findings for clinical practice and/or further research: Also, the circulating Chemerin level was positively correlated with insulin index, which we thought would add to the evidence that Chemerin does be associated with GDM, contributing to elucidating the pathogenesis of GDM.

MILD cognitive impairment , *PHYSIOLOGICAL effects of estradiol , *FOLLICLE-stimulating hormone , *MONTREAL Cognitive Assessment - Abstract
Background: Estrogen has been proved to have positive effects on the brain cognitive function. However, many clinical studies investigating the associations between cognitive functions and circulating estrogen levels in perimenopausal and postmenopausal women demonstrated controversial results. Method: Circulating estradiol and follicle stimulating hormone (FSH) levels were obtained from 199 perimenopausal and postmenopausal women (mean age: 49.61 years). The cognitive function has been assessed using the Beijing version of the Montreal Cognitive Assessment. Results: Results revealed that higher estradiol levels were associated with better cognitive function (p < 0.05) both in perimenopausal and postmenopausal women and levels of FSH were unrelated to cognitive performance. Conclusions: In perimenopausal and postmenopausal women, higher levels of circulating estradiol are associated with lower risk of cognitive impairment. [ABSTRACT FROM AUTHOR]

Objective: To explore and develop a new in vitro implantation model that reflects the main process of embryo attachment and invasion. Study design: One of the limitations in human embryo implantation research is lack of an available in vitro model that faithfully replicates human embryo-uterine interactions. In the present study, we examined the attachment and invasiveness of blastocysts from mice in Ishikawa cell (IK), a human endometrial cell, to clarify whether this new model is suitable to study implantation of embryos. We used IK and placed it in contact with blastocysts to initiate coculture experiments using a specifically designed medium. The culture medium was composed of Ham F-12/Dulbecco's modified Eagle medium (1:1), 30% fetal calf serum, 63.5 nmol/L progesterone, 7.14 nmol/L estradiol-17β, 100 mg/ml of insulin, and 20 ng/ml epidermal growth factor. The culture for 24 h clearly demonstrated that embryos were capable of attachment to the IK and displayed partial invasion. Results: Our results showed that embryos attached to the IK and displayed partial invasion after coculture of blastocysts with IK for 48 h. Conclusions: The model is capable of demonstrating the procedure of attachment and invasion of embryo into the endometrial cells and has promises to be used in studies related to early embryo implantation in human endometrium.

Objective. To explore the effects of overweight and obesity on the outcomes of in vitro fertilisation (IVF) in Chinese infertile patients. Study design. A retrospective cohort study was carried out in 2222 normal weight (18.5 ≤ BMI < 25), 379 overweight (25 ≤ BMI < 30) and 27 obese (BMI ≥ 30) women who underwent their first IVF cycles between 2002 and 2008. Cycle characteristics and IVF outcomes were analysed. Results. Obese women required significantly higher dose of rFSH (3272 IU vs. 2587 IU, p < 0.001) and days of stimulation (11.89 ± 4.57 vs. 10.42 ± 2.03, p < 0.001), but exhibited less oocytes retrieved and significantly lower fertilisation rate (54.1% vs. 61.1%, p < 0.001) than normal weight women. Compared with normal weight women, overweight women displayed significantly less oocytes retrieved (12.98 ± 6.91 vs. 14.49 ± 7.96, p < 0.001), lower fertilisation rate (60.8 ± 23.3 vs. 61.1 ± 23.0, p < 0.001), less cleavaged embryos (7.55 ± 4.86 vs. 8.67 ± 5.90, p < 0.001), less high-grade embryos (4.65 ± 3.96 vs. 5.59 ± 4.81, p < 0.001) and cryopreserved embryos (4.44 ± 4.55 vs. 5.49 ± 5.55, p < 0.001). All parameters of pregnancy outcomes, including pregnancy rate, miscarriage rate and live birth rate, were comparable among three groups. Conclusions. Overweight and obesity are related with impared ovarian response, and negatively affect the outcomes of IVF. [ABSTRACT FROM AUTHOR]
