Objective: To analyze the correlation between salivary cortisol content and anxiety and depression in pregnant and postpartum women. Method: 300 pregnant and postpartum women who were admitted from January 2021 to December 2021 were selected as the research subjects. They were all tested with the Hamilton Anxiety Scale (HAMA) and the Edinburgh Postnatal Depression Scale (EPDS). 40 pregnant women with anxiety and depression were selected as the observation group, and 50 normal pregnant women were selected as the control group, adopting logistic regression analysis to investigate the correlation between salivary cortisol and postpartum anxiety and depression during pregnancy. Result: The salivary cortisol levels in the observation group were significantly higher than those in the control group before bedtime, after waking up the next day, 15 minutes after waking up, 30 minutes after waking up, 60 minutes after waking up, and 1 hour before lunch (p 0.05). Maternal depression and anxiety are closely related to salivary cortisol levels and educational background (p Conclusion: There is a close correlation between anxiety and depression and an increase in cortisol levels, suggesting that the salivary cortisol awakening response during pregnancy has a predictive effect on the occurrence of postpartum depression.

宫腔粘连(intrauterine adhesion,IUA)也称为Asherman综合征,是指子宫内膜基底层损伤后继发的宫颈管或子宫腔部分或全部闭塞。虽然Asherman综合征被广泛定义为妊娠后子宫腔粘连,但其更为准确的定义应为伴有闭经的子宫腔完全闭锁。若是... 详细信息

宫腔粘连(intrauterine adhesion,IUA)也称为Asherman综合征,是指子宫内膜基底层损伤后继发的宫颈管或子宫腔部分或全部闭塞。虽然Asherman综合征被广泛定义为妊娠后子宫腔粘连,但其更为准确的定义应为伴有闭经的子宫腔完全闭锁。若是描述子宫腔受到创伤后发生的宫腔不同程度的粘连,包括子宫腔或宫颈管壁的完全闭塞,“宫腔粘连”会更为合适。IUA无法自我修复,常导致月经量减少或闭经、周期性腹痛、流产或不孕。随着我国计划生育政策的放开及宫腔手术的普及,IUA的发病率逐年升高,逐渐成为继发不孕的首要原因。

规模化猪场二元母猪繁殖率高低是影响商品场生产效率的重要前提因素,为分析影响二元杂交母猪繁殖性能的因素,以某规模化猪场2023年二元杂交母猪全年繁殖生产记录数据为依据,从年龄(胎次)和繁殖季节2个方面进行整理分析,旨在掌握影响二元杂交母猪繁殖的重要因素,为商品场二元母猪的科学管理提供依据。结果显示,母猪产仔性能中胎次对其影响差异极显著(P<0.01),在第3~6胎时呈上升趋势,第4胎时产仔性能最佳,第7胎时明显下降。产仔月份对母猪产仔性能的影响不显著,随着饲养管理水平的提升,月份对母猪的影响逐渐降低。规模化猪场可以根据第4胎时的母猪产仔情况对猪群年龄结构进行调整,加大第3~6胎次的母猪比重,及时淘汰低产母猪,更新猪群。
