BackgroundThis study aims to evaluate the choroidal vascularity index in patients with idiopathic epiretinal membrane at different stages.MethodsThis prospective study included 125 eyes of 125 patients with idiopathic epiretinal membrane and 62 eyes of 62 healthy control subjects. In this study, epiretinal membrane stages were defined based on the spectral-domain optical coherence tomography staging system. The choroidal vascularity index was measured as the ratio of the luminal area to the stromal area in the central 1500 μm after binarization on enhanced depth imaging optical coherence tomography images. Data on epiretinal membrane stages, choroidal vascularity index, and best-corrected visual acuity were noted.ResultsOf 125 eyes with epiretinal membrane, 38 (30.4 %) had stage 1, 32 (25.6 %) had stage 2, and 55 (44 %) had stage 3 disease. Visual acuity was better in eyes with stage 1 or 2 epiretinal membrane than those with stage 3 epiretinal membrane (p < 0.001). The mean choroidal vascularity index was 2.29 ± 1.02 in the control, 2.23 ± 0.98 in the stage 1 epiretinal membrane, 2.22 ± 0.91 in the stage 2 epiretinal membrane, and 2.23 ± 1.11 in the stage 3 epiretinal membrane group. There was no significant difference between epiretinal membrane subgroups and the control group regarding the choroidal vascularity index (p = 0.81).ConclusionFrom the results obtained in the present study, the choroidal vascularity index was not effected by either the development or the progression of idiopathic epiretinal membrane.  相似文献

目的 描述糖尿病足高危患者的足部自护行为及其阶段分布,并进行影响因素分析.方法 对343例糖尿病足高危患者应用一般资料问卷、糖尿病患者足部护理行为问卷、行为阶段表、第三版糖尿病态度量表、社会支持评定量表和糖尿病自我效能量表进行横断面调查.结果 糖尿病足高危患者的足部自护行为得分28~68(47.50±7.30)分,百分制标准得分为59.81分.足部自护行为意图前期、意图期、准备期、行动期和维持期分别为11.7%、35.6%、41.7%、5.8%和5.2%.有序Logistic回归分析显示:性别、支付方式、感知社会榜样、疾病认知态度和自我效能是影响患者行为阶段分布的主要因素(P<0.05,P<0.01).结论 糖尿病足高危患者的足部护理行为总体水平低,多数患者的足部自护行为处于前期阶段;患者的足部自护行为受多种因素影响,医务人员应结合相关因素,对不同行为阶段的患者采取针对性干预策略,以促进其足部自护行为的阶段性转变.  相似文献

We investigated the effect of acute concentrations of triclosan (TCS; 96 h exposure and 10d post exposure) on the free amino acid, primary (SDS-PAGE) and secondary (FT-IR) structure of proteins in the embryos/larvae of Cyprinus carpio, Ctenopharyngodon idella, Labeo rohita and Cirrhinus mrigala. A concentration dependent increase in free amino acids, upregulation of polypeptides (100 and 70 kDa in C. carpio, C. idella and L. rohita, 55, 45, 36 kda in C. idella and L. rohita and 22 kDa in all the fish) and a decline in percent area of all the selected peaks of the FT-IR spectra was observed after exposure and recovery period. The decline in percent area was greatest for L. rohita at peak 1080 – 1088 cm−1 (−75.99%) after exposure and at peak 2854 – 2855 cm−1 (−53.59%) after recovery. Curve fitting analysis revealed a decrease in α-helices and increase in β-sheets in all fish after exposure and recovery period. The results suggest that TCS elicits alterations in biomolecules of fish embryos.  相似文献

IntroductionThere is limited understanding of how burn injuries at different ages are associated with normal growth and development as well as the burn recovery process. This study provides new useful insights by comparing social participation outcomes among burn survivors injured in childhood compared with injuries sustained in middle age, and older adulthood.MethodsItems from the development of the LIBRE profile were administered to 601 adult burn survivors with ≥5% TBSA burned or burns to critical areas (hands, feet, face, or genitals). Each item was answered on a 5-point Likert scale with higher scores denoting better outcomes. Mean scores for the 6 LIBRE profile scales (sexual relationships, family and friends, social interactions, social activities, work and employment, and romantic relationships) were compared between those burned as children (<18 years) and those burned as adults (≥18 years). Regression analyses were used to assess differences between groups with adjustment for demographic and clinical characteristics.ResultsOf the 597 burn survivors having complete data on age at injury, 165 (27.6%) sustained burn injuries as a child. Those burned as children were more frequently female than those burned as adults (57% vs 47%) and were also more frequently white non-Hispanic (89% vs 77%). Marital status and education level were similar in the two groups. Those who were burned as children had slightly higher scores on the social activities, work and employment and romantic relationships scales. However, these differences did not persist in adjusted regression analyses.ConclusionsBurn survivors who sustained injuries as a child fared at least as well as those burned as adults in a broad range of long-term social participation outcomes. The impact on long-term social participation outcomes of burn survivors was not significantly different between individuals with burns sustained during important developmental stages at young ages and those injured later in life.  相似文献

目的探讨产前乳房按摩点穴对缩短产程和产后泌乳的影响。方法选择符合阴道试产的经产妇100例,按时间先后顺序分为观察组和对照组各50例。对照组采用常规护理方法,观察组由助产师进行产前乳房按摩点穴,每日2次,每次30 min。比较两组宫缩情况、产程时间、乳汁分泌始动时间。结果入院3 d内两组孕妇规律宫缩及分娩率、产妇泌乳始动分布比较,差异有统计学意义(均P0.01);观察组第二、三产程时间及总产程时间显著短于对照组(均P0.01)。结论产前乳房按摩点穴有利于诱发宫缩,缩短产程,促进产妇产后泌乳。  相似文献

目的 探讨不同时间进行硬膜外镇痛对产程时间的影响和母婴分娩结局的影响。方法 选取我院收治的产妇165例为研究对象,选取的时间范围为2016年3月~2019年2月,按照产妇入院顺序分为活跃组、潜伏组和自然组,每组55例,活跃组产妇进行活跃期硬膜外镇痛,潜伏组产妇进行潜伏期硬膜外镇痛,自然组产妇进行自然分娩。观察三组产妇的产程时间、产妇的分娩状况以及不同时间点的视觉模拟评分(VAS),以及采用Apgar评分判断新生儿窒息情况。结果 潜伏组产妇的宫口扩张速度明显快于活跃组和自然组,潜伏期产妇的活跃期和第二产程明显短于活跃组和自然组,差异有统计学意义(P0.05);三组产妇的第三产程差异无统计学意义(P0.05)。活跃组和潜伏组产妇的缩宫素使用率分别为50.91%和45.45%,明显高于自然组18.18%,产妇器械助产率分别为25.45%和30.91%,明显高于自然组14.54%,差异有统计学意义(P0.05);活跃组和潜伏组产妇的剖宫产率分别为9.09%和7.27%,明显低于自然组21.82%,差异有统计学意义(P0.05);三组产妇的顺产率差异无统计学意义(P0.05);三组新生儿的窒息情况差异无统计学意义(P0.05)。分娩后10 min和40 min,自然组产妇的VAS评明显高于活跃组和潜伏组,差异有统计学意义(P0.05)。结论 在潜伏期对产妇进行硬膜外镇痛可以缩短产妇的活跃期和第二产程时间,加快宫口扩张,减轻产妇的疼痛,提高母婴结局。  相似文献

目的探讨血清促甲状腺激素(TSH)、肿瘤特异性生长因子(TSGF)水平、p185蛋白阳性率与乳腺癌疾病的相关性。方法选择2016年8月至2018年10月应城市人民医院收治的60例乳腺癌患者作为研究对象,按照TNM分期分为Ⅰ-Ⅱ组(Ⅰ-Ⅱ期患者)36例和Ⅲ-Ⅳ组(Ⅲ-Ⅳ期患者)24例,另选取我院同期健康体检人群60例作为对照组。对比分析3组患者血清TSH、TSGF水平及p185蛋白阳性率及不同病理特征下患者TSH、TSGF水平及p185蛋白阳性率之间的差异,分析联合检测和单独检测之间的差异。结果3组间TSH、TSGF水平及p185蛋白阳性率比较,差异有统计学意义(P<0.05)。与对照组相比,Ⅰ-Ⅱ组和Ⅲ-Ⅳ组患者血清中TSH、TSGF水平及p185蛋白阳性率更高,差异有统计学意义(P<0.05)。不同组织分级、TNM分期以及淋巴结转移情况的乳腺癌患者的TSH、TSGF水平及p185蛋白阳性率比较,差异有统计学意义(P<0.05);而不同肿瘤直径和分子分型的乳腺癌患者的TSH、TSGF水平及p185蛋白阳性率比较,差异无统计学意义(P>0.05)。Spearman相关性分析显示,组织分级、TNM分期、淋巴结转移、病理状态与乳腺癌患者的TSH、TSGF水平及p185蛋白阳性率呈显著相关性(P<0.05)。Logistic多因素分析结果显示,血清TSH(OR=1.019,P=0.001)、TSGF(OR=1.632,P=0.001)、p185蛋白阳性率(OR=1.089,P=0.000)是乳腺癌发生的独立危险因素。ROC诊断曲线结果显示,联合血清TSH、TSGF水平及p185蛋白阳性率的诊断效能显著高于单独指标的诊断效能(P<0.05)。结论乳腺癌患者的血清TSH、TSGF水平及p185蛋白阳性率与病理分期显著相关,且联合检测诊断效能更高,可作为诊断的依据。  相似文献
