Excessive alcohol intake can lead to damage of various organs, including the liver. Alcoholic liver disease includes different injuries ranging from steatosis to cirrhosis and implicates a diagnostic assessment of the liver disease and of its possible complications. There is growing interest in the possible different tools for assessing previous alcohol consumption and for establishing the severity of liver injury, especially by noninvasive methods.展开更多
目的分析胎儿超声心动图联合母体血清分泌型卷曲相关蛋白5(secreted frizzled-related protein 5,SFRP5)、同型半胱氨酸(homocysteine,Hcy)浓度对先天性心脏病(先心病)胎儿的诊断效能。方法选取2018年7月至2022年2月在十堰市妇幼保健院...目的分析胎儿超声心动图联合母体血清分泌型卷曲相关蛋白5(secreted frizzled-related protein 5,SFRP5)、同型半胱氨酸(homocysteine,Hcy)浓度对先天性心脏病(先心病)胎儿的诊断效能。方法选取2018年7月至2022年2月在十堰市妇幼保健院进行孕中期产前检查的孕妇2756例为研究对象,根据妊娠结局将孕妇分为先心病组(n=110),正常组(n=2646)。孕中期均行胎儿超声心动图检查。酶联免疫吸附法试验(enzymelinked immunosorbent assay,ELISA)检测母体血清SFRP5浓度,全自动生化分析仪检测Hcy浓度。Pearson法分析先心病组母体血清SFRP5浓度与Hcy浓度的相关性。以妊娠结局为“金标准”,分析胎儿超声心动图、母体血清SFRP5、Hcy浓度及三者联合对先心病胎儿的诊断效能。结果先心病组母体血清SFRP5浓度明显低于正常组(P<0.05),Hcy浓度明显高于正常组(P<0.05),两者浓度呈负相关(r=-0.575,P<0.05)。胎儿超声心动图、母体血清SFRP5、Hcy浓度诊断先天性心脏病胎儿的灵敏度分别为63.64%、64.55%、65.45%,特异度分别为81.52%、81.07%、80.35%,准确度分别为80.81%、80.41%、79.75%。胎儿超声心动图、母体血清SFRP5、Hcy浓度联合诊断先心病胎儿的灵敏度、准确度分别为96.36%、80.91%,均高于三者单独检测,且三者联合诊断的灵敏度显著高于三者单独诊断(P<0.05)。结论胎儿超声心动图联合母体血清SFRP5、Hcy浓度对先心病胎儿具有较高的诊断价值,三者联合诊断可提高灵敏度。展开更多

Land use and landscape changes in highway buffer zones and city expansion are special subjects. A new formula is used to define the exact degree of dynamic land use. To adequately define land use and landscape pattern changes, the buffer zones, illustrating the changes at different distances from the road, are recognized with ArcGIS 8.1 software. Prominent changes took place in land use and landscape patterns from 1995 to 2000, and the area of built-up land increased by 323.8%. The comprehensive degree of dynamic land use is 2.25, and the degree of dynamic land use of built-up land is the highest, followed by cultivated land. Woodland has the lowest value. The used degree index of land resources declined by 38.8 from 1995 to 2000. Landscape changed dramatically which influenced ecological processes immensely. Different from the corridor effect of other traffic routes, the corridor effect of this section of road is not obvious and its “point” radiation effect can be easily seen. The expanding range of Golmud City is confined to a 3 km buffer, while for Wudaoliang, it is 1 km. No land use change happened in the Nanshankou buffer.展开更多

We also studied whether the underlying motility disorder could be predicted from EGG parameters. METHODS: We compared 21 parameters measured from EGG with 8 parameters measured from ADM. The ability of EGG to identify the underlying diagnosis was tested by comparing EGG parameters for each diagnosis group against other patients. The study comprised recordings from 148 patients and 125 females. Their median age was 45 (range 17-76) years. RESULTS: We found few and weak correlations between EGG and ADM. Specifically the correlation between parameters reflecting the response to meal was poor (r = -0.07, P = 0.39). The discriminatory power of EGG for underlying motility disorder was also low. Patients with slow transit constipation (STC) showed a lower postprandial power in normogastric (3.7 ± 0.5 vs 4.0 ± 0.5) and tachygastric (3.5 ± 0.4 vs 3.7 ± 0.4) regions, a lower percentage of time with normogastria [87.2 (56.5-100)% vs 95.7 (0-100)%], and a higher percentage of time with tachygastria [9.3 (0-33)% vs 3.5 (0-100)%] and bradygastria [1.8 (0-20)% vs 0 (0-17.1)%]. Patients with irritable bowel syndrome had a higher percentage of time with normogastria [96.5 (62.5-100)% vs 93.3 (0-100)%] and a less unstable dominant frequency as measured by the instability coefficient [15 (3-77) vs 24 (2-72)]. CONCLUSION: EGG and ADM seem to measure different aspects of gastric motor activity but cannot show a spatial correlation. The diagnostic value of EGG is poor, but EGG may have some value for the identification of patients with STC.展开更多
