Effect of behavior training on learning,memory and the expression of NR2B,GluR1 in hippocampus of rats offspring with fetal growth restriction

Objective： To study effects of behavior training on learning, memory and the expression of NR2B, GluR1 in hippocampus of rat＇ s offspring with fetal growth restriction（FGR）. Methods： The rat model of FGR was established by passive smoking method. The rats offspring were divided into the FGR group and the control group, then randomly divided into the trained and untrained group, respectively. Morris water maze test was proceeded on postnatal month（PM2/4） as a behavior training method, then the learning-memory of rats was detected through dark-avoidance and step-down tests. The expressions of NR2B and GluR1 subunits in hippocampal CA1 and CA3 areas were detected by immunohistochemical method. Results： In the dark-avoidance and step-down tests, the performance record of rats with FGR was worse than that of control rats, and the behavior-trained rats was better than the untrained rats, when the FGR model and training factors were analyzed singly. The model factor and training factor had significant interaction（P 〈 0.05）. The expressions of NR2B and GluR1 subunits in hippocampal CA1 and CA3 areas of rats with FGR reduced. In contrast, the expressions of GluR1 and NR2B subunits in CA1 area of behavior-trained rats increased, when the FGR model and training factors were analyzed singly. Conclusion： These findings suggested that the effect of behavior training on the expressions of NR2B and GluR1 subunits in CA1 area should be the mechanistic basis for the training-induced improvement in learning-memory abilities.

Effect of cognitive behavior therapy training and psychological nursing on the midwifery process in the delivery room

BACKGROUND The severe physical and psychological impact of pain on the physical and mental health of women during labor leads to increased risks and complications during childbirth,presenting a major public health concern.Some studies have shown that cognitive behavioral therapy(CBT)has a positive effect on maternal psychology during delivery,reducing stress and shortening labor time.Thus,CBT training for mothers and delivery room staff may be beneficial in minimizing complications and adverse effects during natural birth.AIM To investigate the clinical effects of CBT training and psychological care during delivery,and their therapeutic effects on women in labor.METHODS This study used a retrospective analysis and included 140 mothers admitted to the maternity ward between January 2021 and January 2023.The study subjects were randomized into two groups:control(n=70)and observation(n=70).Routine care,CBT training,and psychological care were provided to mothers in both groups.Psychological status scores,delivery time,and satisfaction with care pre-and post-delivery were compared,and the incidence of complications after receiving care was analyzed between the two groups.RESULTS Although the psychological state of both groups improved significantly in the late stages of labor,the psychological state scores of the mothers in the observation group were significantly lower than those of the mothers in the control group(P<0.05).The duration of labor and incidence of complications in the observation group were significantly lower than those in the control group(P<0.05).The mothers in the observation group were significantly more satisfied with nursing care during the course of labor than those in the control group(P<0.05).CONCLUSION CBT training and psychological care for mothers in the midwifery process can effectively improve anxiety and depression,shorten labor duration,reduce postnatal complications,and improve nursing satisfaction and nurse-patient relationships.Its clinical application is effective and has popularization value,providing a new way to protect maternal mental health.
