地震灾害对分娩的影响

目的:观察地震灾害对分娩的影响。方法:对我院2008年5月12日至2008年6月12日在地震期间分娩的216例产妇进行回顾性分析。结果:阴道分娩率较地震前比较明显上升,剖宫产率明显下降。结论:地震灾害致孕妇的心理发生变化,导致阴道分娩率上升剖宫产率明显下降。     

超声造影在肝癌介入治疗后疗效评价中的应用

目的:探讨实时灰阶超声造影(contrast-enhanced grey-scale ultrasonography,CE-US)在肝癌介入治疗后疗效评价中的应用价值。方法:经肘前浅静脉团注超声对比剂SonoVue,观察各时相病灶的强化特点,并与治疗前CE-US、治疗后CT、MRI图像及随访结果进行比较,综合判断介入治疗效果。结果:CE-US可以清晰地显示病灶内有无局部或整体强化,能准确评价肝癌介入治疗后疗效。结论:CE-US在评价肝癌介入疗效时具有重要的临床价值。     

蛋白酶对降低异常精液粘稠度的实验对比研究

目的通过不同蛋白酶类对降低高粘稠度精液的粘稠度效果对比,寻找理想的降低精液粘稠度的药物。方法将高粘稠度精液标本分为两组,A组:31例采用α-糜蛋白酶降低精液粘稠度:B组:32例采用尿激酶降低精液粘稠度;两组均观察用药前后的精子活动力。采用配对t检验和单因素方差分析对所得数据作统计学处理。结果高粘稠度精液用药物(α-糜蛋白酶或者尿激酶)液化精液后,精子的活动力较用药前有明显提高(P<0．001);用药前后精液的粘稠度都存在着明显的差异,精液的粘稠度分别下降44．83％和55．45％(P<0．001);在A组和B组的对比研究中,单因素方差分析检验提示:用药后两组间粘稠度数据有显著的差异(P<0．001￡(?)。结论蛋白酶可以有效地降低异常精液粘稠度的精液,从实验结果提示尿激酶降低精液粘稠度的效果优于α-糜蛋白酶,这有助于临床开展应用性研究和治疗。     

慢性肾功能不全患者血管活性物质测定在血液净化中的临床研究

目的 评价血管紧张素Ⅱ、氨甲酰血红蛋白、醛固酮及甲状旁腺激素等在血液净化充分性中的意义。方法 120例慢性肾功能衰竭患者，按采用不同的透析膜分为3组：即聚砜膜、醋酸膜、铜仿膜。用放射免疫法测定其血管紧张素Ⅱ（AngⅡ）及醛固酮（ALD）浓度，化学发光法测甲状旁腺激素（PTH）。采用不同的血流量200ml／min及250ml／min比较。结果 对体内中、小分子物质清除率，聚砜膜〉醋酸膜〉铜仿膜。结论 高血流量、高通透性人工合成聚砜膜，对治疗慢性肾功能衰竭，提高肾功能不全患者的身心健康及生活质量、延长患者生命有很重要的临床意义。     

Using rare earth element tracers and neutron activation analysis to study rill erosion process.

Spatially averaged soil erosion data provide little information on the process of rill erosion. The dynamically varied data on the temporal and spatial distributions in the rill erosion process are needed to better understand the erosion process and reveal its innate characteristics. The objectives of this study were to examine the feasibility and effectiveness of rare earth element (REE) tracers and the neutron activation analysis (NAA) method on the study of the rill erosion process and to reveal quantitatively the relationships and characteristics of temporal and spatial distributions of sediment yield in rill erosion. Four REEs were used to study the changeable process of rill erosion at 4 slope positions. Four water inflow rates were applied to a 0.3 x 5 m soil bed at 3 slopes of 10.5%, 15.8% and 21.2% in scouring experiments. All of the runoff was collected in the experiment. Each sample was air-dried and well mixed. Then 20 g of each sample was sieved through 100-mesh and about a 50 mg sample was weighed for analysis of the four elemental compositions by NAA. Results indicate that the REE tracers and NAA method can be used to not only quantitatively determine soil erosion amounts on different slope segments, but also to reveal the changeable process of rill erosion amount. All of the relative errors of the experimental results were less than 25%, which is considered satisfactory on the study of rill erosion process.     

The role of endotoxin in the pathogenesis of experimental multiple system organ failure: a preliminary report.

In this study, an animal model of multiple system organ failure (MSOF) in rabbits, engendered by feeding E. coli prior to severe hemorrhagic shock, was used for the purpose of investigating 1) the relationship between lipopolysaccharide (LPS) and MSOF, and 2) the effectiveness of Re-LPS antiserum in preventing MSOF. The results showed that endotoxemia occurred very early, and its degree correlated well with that of organ dysfunction. Re-LPS antiserum administration abated the toxic effects and lowered the incidence of MSOF. These results suggest that sequential analysis of circulating LPS levels may be useful for the early diagnosis of MSOF, and that gut-derived endotoxin might play an important role in the pathogenesis of experimental MSOF.
