With the changes in lifestyle, marriages and childbearing concepts, and population policies in recent years, the proportion of women with advanced maternal age (AMA) in China is rising rapidly. AMA and maternal stress due to advanced age are considered as independent risk factors for maternal mental health and the neurobehavioral development of their offspring. In this paper, we summarized how the glial cell line-derived neurotrophic factor, the hypothalamic-pituitary-adrenal axis, the 5-HT system and the oxytocin affect the maternal mental health and the neurobehavioral development of their offspring, as well as some potential targeted interventions. Interventions currently being developed include artificial supplements, antidepressants, physical exercise, nutrient supplementation, etc., but they have a limited efficacy and a high risk of side effects, yet there is still a lack of specific and systematic interventions. The relevant pathogenesis should continue to be explored in the future research, and hopefully more effective and safe interventions will be given in the near future to improve the mental health of mothers with AMA and the long-term healthy development of their offspring.

Objective To observe the value of MRI texture features combined with apparent diffusion coefficient(ADC)for differentiating uterine sarcoma(US)and cellular uterine leiomyoma(CUL).Methods Pelvic MRI data of 27 US patients(US group)and 34 CUL patients(CUL group)were retrospectively analyzed.The texture features of lesions were extracted from T2WI and diffusion weighted imaging(DWI),the ADC value were measured,and the average ADC value(ADCmean),the minimum ADC value(ADCmin)and standard ADC value(ADCst)were recorded.Then logistic regression(LR)models were constructed based on ADC value,optimal texture features alone and their combination,respectively,including LRADC,LRtexture and LRADC+texture models.Receiver operating characteristic curves were drawn,and the area under the curves(AUC)were calculated to evaluate the efficacy of each model for differentiating US and CUL.Results The ADCmean,ADCmin and ADCst in US group were all lower than those in CUL group(all P＜0.05).A total of 3 750 texture features were extracted from pelvic T2WI and DWI,5 optimal features were finally obtained,and the constructed LRADC+texture model and LRtexture model had similar efficacy of differentiating US and CUL(AUC=0.921,0.887;P＞0.05),which were both higher than that of LRADC model(AUC=0.696;both P＜0.05).The calibration curve of LRADC+texture model was basically consistent with the ideal curve,which had better clinical benefits than LRADC and LRtexture models.Conclusion MRI texture features combined with ADC value could improve efficacy for differentiating US and CUL.

Objective: To compare the weight loss and metabolic profile between a continuous energy-restricted diet and intermittent fasting diet in order to present an optimal nutritional weight reduction method for obese people in China. Methods: Sixty overweight or obese adults were selected and divided into two groups as the continuous energy-restricted diet group and the intermittent fasting diet group. Height, weight, waist circumference, body mass index(BMI), body fat, change of visceral fatarea, fasting glucose(FPG), triglyceride(TG), total cholesterol(TC), high density cholesterol(HDL), low density cholesterol(LDL), glutamic pyruvicaminotransferase(AST), signglutamic pyruvic transaminase(ALT), gamma-glutamyltranspeptidase(GGT), alkalinephosphatase (ALP), fasting insulin level(FINS) and HOMA-IR were assessed at baseline and 8 weeks after weight loss methods carried. Results: Both continuous energy-restricted diet and intermittent fasting diet resulted improvement on body shape indexes and a significant decrease in weight, waist circumference, BMI, body fat, visceral fat area and skeletal muscle(P<0.01)at 8 weeks. Both groups experienced improvements in biochemical outcomes and metabolic indicators at 8 weeks. A significant reduction in TC, AST, ALT, GGT, ALP, FINS and HOMA-IR(P<0.01 or P<0.05)were observed in continuous energy-restricted diet group. And a significant decline in TC, LDL, HDL, AST, ALT, GGT, ALP, FINS and HOMA-IR were observed in intermittent fasting diet group(P<0.01 or P<0.05). HDL was found significantly reduced in intermittent fasting diet group as compared with continuous energy-restricted diet group(P<0.01) at 8 weeks, however, there were no difference in weight loss, waist circumference, BMI, body fat, visceral fat area and other metabolic indicators at 8 weeks(P>0.05). Conclusion Both intermittent fasting diet and continuous energy-restricted diet have a similar effect on weight loss and metabolic indexes like blood glucose, HOMA-IR and blood lipid, but intermittent fasting diet can more significantly decrease HDL level.
