目的研究分析高龄孕妇妊娠晚期心电图与妊娠结局的关系。方法选取我院收治的100例妊娠晚期孕妇,实验组患者为高龄妊娠晚期,年龄>35岁。对照组为适龄孕妇,年龄<35岁。每组各50例。两组孕妇均进行心电图检查,比较分析实验组与对照... 目的研究分析高龄孕妇妊娠晚期心电图与妊娠结局的关系。方法选取我院收治的100例妊娠晚期孕妇,实验组患者为高龄妊娠晚期,年龄>35岁。对照组为适龄孕妇,年龄<35岁。每组各50例。两组孕妇均进行心电图检查,比较分析实验组与对照组孕妇心电图异常发生率及与妊娠结局的关系。结果实验组中,异常心电图例数为17例。对照组中,异常心电图例数为7例。实验组与对照组异常心电图发生率分别为34.0%、14.0%,差异有统计学意义(P<0.05)。对照组中异常心电图孕妇早产例数为1例,实验组为5例。实验组与对照组异常心电图孕妇早产率分别为29.4%、14.3%,差异有统计学意义(P<0.05)。实验组异常心电图中发生低体重新生儿几率为11.8%,显著高于对照组的0.0%,差异有统计学意义(P<0.05)。结论高龄孕妇妊娠晚期异常心电图主要为ST-T与心率失常,异常心电图高龄孕妇剖宫产率及早产率较高,易发生新生儿低体重,需关注心电图变化,做好治疗工作。 展开更多

Poultry and eggs are nutritious and healthy foods that contain high-quality proteins and low levels of fat compared with other meats. Recent studies have shown that poultry performance is closely associated with colonic health. Antibiotics are commonly used in the poultry industry to control diseases and enhance survival rates. However, antibiotic use can also result in host gut dysbiosis and immune dysregulation. Such imbalances compromise poultry health and growth performance. Thus, our study investigated the effect of Lactobacillus(L.) plantarum P-8 on the gut microbiome of chickens co-inoculated with the antibiotic lincomycin. Principal coordinate analysis showed that L. plantarum P-8 treatment shifted the faecal bacterial population structure. At the metagenomic level, the Clusters of Orthologous Groups(COGs) functional categories of P, C, N and A were overrepresented in the probiotic group. Additionally, the relative gene abundances of metabolic pathways involved in flagellar assembly,bacterial chemotaxis, nitrogen metabolism, sulfur metabolism, cofactor and vitamin biosynthesis were also higher in the probiotic group than the control; in contrast genes related to galactose degradation,carbon fixation, multiple sugar transport systems and ribosomes were underrepresented in the probiotic group. Our data suggest that feeding L. plantarum P-8 has the potential to improve metabolic activity and nutrient utilization of poultry. Furthermore, the faecal antibiotic resistomes of the two groups could be separated using principal components analysis, indicating that the probiotic treatment may modulate the intestinal antibiotic resistance gene pool by changing the population structure of the gut microbiota.This study has provided interesting insights into the application of probiotics in the poultry industry. 展开更多
