摘要 目的:研究双针刺疗法在孕足月初产妇催产中的应用效果及对应激反应和内源性神经递质的影响。方法:选取2020年3月~2022年5月期间我院妇产科收治的孕足月初产妇102例。根据随机数字表法分为对照组(51例)和研究组(51例)。产妇在临产宫口开至3 cm(T0)后,对照组不予以任何镇痛方法干预,研究组给予双针刺疗法干预。比较两组催产疗效、产程情况、宫颈成熟指标、应激反应和疼痛、内源性神经递质指标的变化情况。结果:研究组的临床总有效率高于对照组(P<0.05)。研究组的总产程、第一产程、第二产程、第三产程时间均短于对照组(P<0.05)。研究组的宫颈口扩张、宫颈管消退、先露位置、宫颈硬度、宫口位置大于对照组(P<0.05)。两组宫颈口开10 cm(T1)的血糖、皮质醇水平升高,但研究组低于对照组(P<0.05)。两组T1的视觉疼痛模拟(VAS)评分、P物质(SP)、β-内啡肽(β-EP)、神经肽Y(NPY)升高,但研究组低于对照组(P<0.05)。结论:孕足月初产妇采用双针刺疗法可提高催产疗效,促进宫颈成熟,缩短产程时间,同时还可减少内源性神经递质的释放,减轻产妇应激反应。  相似文献

摘要 目的:探讨不同分娩镇痛时机对初产妇产程进展、母婴结局及早期盆底功能的影响。方法:选择2019年4月至2022年8月我院收治的148例拟接受硬膜外分娩镇痛的产妇,按照随机数字表法分为两组。A组(74例)于宫口扩张≤2 cm开始分娩镇痛,B组(74例)于宫口扩张>2 cm进行分娩镇痛。比较两组产程、宫口扩张全时间、催产素使用、疼痛、母婴结局、盆底肌电指标以及盆底障碍发生情况。结果:A组宫口扩张全时间、第一产程、第二产程、压力性尿失禁发生率低于B组(P<0.05),催产素使用率、中转剖宫产率高于B组(P<0.05)。A组给药30 min(T1)、60 min(T2)、宫口扩张7-8 cm(T3)、宫口扩张全(T4)视觉模拟评分法(VAS)评分均低于B组(P<0.05)。A组Ⅰ类肌纤维肌电压、Ⅱ类肌纤维肌电压高于B组(P<0.05),Ⅰ类肌纤维疲劳度绝对值、Ⅱ类肌纤维疲劳度绝对值低于B组(P<0.05)。结论:宫口扩张≤2 cm实施硬膜外分娩镇痛,可降低分娩对女性盆底肌群的损伤;宫口扩张>2 cm实施硬膜外分娩镇痛,中转剖宫产率、产程中催产素使用率相对较低,应结合产妇的个体情况,综合考虑利弊选择最佳的镇痛时机。  相似文献

The molecular characterisation of species and genotypes of Cryptosporidium and Giardia is essential for accurately identifying organisms and assessing zoonotic transmission. Results of recent molecular epidemiological studies strongly suggest that zoonotic transmission plays an important role in cryptosporidiosis epidemiology. In such cases the most prevalent zoonotic species is Cryptosporidium parvum. Genotyping and subtyping data suggest that zoonotic transmission is not as prevalent in the epidemiology of giardiasis. Molecular characterisation of Cryptosporidium and Giardia is a relatively recent application that is evolving as new genes are found that increase the accuracy of identification while discovering a greater diversity of species and yet unnamed taxa within these two important genera. As molecular data accumulate, our understanding of the role of zoonotic transmission in epidemiology and clinical manifestations is becoming clearer.  相似文献

Today, serious health problems as overweight and obesity are not just constricted to the developed world, but also increase in the developing countries (Prentice 2006, Ramachandram et al. 2002). Focusing on this issue, BMI and percentage of body fat were compared in 2094 schoolchildren from two cross-sectional studies from India and Germany investigated in 2008 and 2009. The German children are in all age groups significantly taller, whereas the Indian children show higher values in BMI (e.g. 12 years: Indian: around 22 kg/m2; German: around 19 kg/m2) and in the percentage of body fat (e.g. 12 years: Indian: around 27%; German: around 18-20%) in most of the investigated age groups. The Indian children have significantly higher BMI between 10 and 13 (boys) respectively 14 years (girls). Indian children showed significant higher percentage of body fat between 10 and 15 years (boys) and between 8 and 16 years (girls). The difference in overweight between Indian and German children was strongest at 11 (boys) and 12 (girls) years: 70% of the Indian but 20% of the German children were classified as overweight. In countries such as India that undergo nutritional transition, a rapid increase in obesity and overweight is observed. In contrast to the industrialized countries, the risk of overweight in developing countries is associated with high socioeconomic status. Other reasons of the rapid increase of overweight in the developing countries caused by different environmental or genetic factors are discussed.  相似文献

The concentration of carnitine in liver increased 28-fold and urinary carnitine excretion 5-fold in alloxan-diabetic sheep. In contrast there were no similar increases in alloxan-diabetic rats. The creatine content of liver decreased 3-fold and creatine excretion decreased 2-fold in diabetic sheep. In contrast the creatine content of liver increased nearly 4-fold in diabetic rats with no change in creatine excretion. The marked increased in production of carnitine by the liver of the diabetic sheep appears possible because of decreased production and excretion of creatine.  相似文献

The nanomechanical properties of the coiled-coils of myosin are fundamentally important in understanding muscle assembly and contraction. Force spectra of single molecules of double-headed myosin, single-headed myosin, and coiled-coil tail fragments were acquired with an atomic force microscope and displayed characteristic triphasic force-distance responses to stretch: a rise phase (R) and a plateau phase (P) and an exponential phase (E). The R and P phases arise mainly from the stretching of the coiled-coils, with the hinge region being the main contributor to the rise phase at low force. Only the E phase was analyzable by the worm-like chain model of polymer elasticity. Restrained molecular mechanics simulations on an existing x-ray structure of scallop S2 yielded force spectra with either two or three phases, depending on the mode of stretch. It revealed that coiled-coil chains separate completely near the end of the P phase and the stretching of the unfolded chains gives rise to the E phase. Extensive conformational searching yielded a P phase force near 40 pN that agreed well with the experimental value. We suggest that the flexible and elastic S2 region, particularly the hinge region, may undergo force-induced unfolding and extend reversibly during actomyosin powerstroke.  相似文献

The synthesis and turnover of cerebrosides and phospholipids was followed in microsomal and myelin fractions of developing and adult rat brains after an intracerebral injection of [U-14C]serine. The kinetics of incorporation of radioactivity into microsomal and myelin cerebrosides indicate the possibility of a precursor-product relationship between cerebrosides of these membranes. The specific radioactivity of myelin cerebrosides was corrected for the deposition of newly formed cerebrosides in myelin. Multiphasic curves were obtained for the decline in specific radioactivity of myelin and microsomal cerebrosides, suggesting different cerebroside pools in these membranes. The half-life of the fast turning-over pool of cerebrosides of myelin was 7 and 22 days for the developing and adult rat brain respectively. The half-life of the slowly turning-over pool of myelin cerebrosides was about 145 days for both groups of animals. The half-life of the rapidly turning-over microsomal cerebrosides was calculated to be 20 and 40 h for the developing and adult animals respectively. The half-life of the intermediate and slowly turning-over microsomal cerebrosides was 11 and 60 days respectively, for both groups of animals. The amount of incorporation of radioactivity into microsomal cerebrosides from L-serine was greatly decreased in the adult animals, and greater amounts of the precursor were directed towards the synthesis of phosphatidylserine. In the developing animals, considerable amounts of cerebrosides were synthesized from L-serine, besides phosphatidylserine. The time-course of incorporation indicated that a precursor-product relationship exists between microsomal and myelin phosphatidylserine. The half-life of microsomal phosphatidylserine was calculated to be about 8 h for the fast turning-over pool in both groups of animals.  相似文献
