查询词典 contrast grade

To compare the image quality of the three sequences in two groups by One-Way ANOVA and T Test. The qualitative assessment standards include clarity, artifacts, signal uniformity, the conspicuity of enhanced vein and the observable grade of intrahepatic venous branchs. The quantitative assessment standards include SNR and CNR of intrahepatic portal vein and hepatic veins. Furthermore, the anatomy and variations of the intrahepatic portal vein and hepatic veins are statistical analysed.

通过方差分析和T检验分别对A、B组三个序列的图像质量进行比较，评定标准包括清晰度、伪影、信号均匀性、静脉强化程度及肝内静脉分支显示级数等定性指标和肝内门静脉、肝静脉的SNR(Signal-Noise Ratio，信噪比)及CNR(Contrast-Noise Ratio，对比度噪声比)等定量指标。

The presence of early CT signs has been reported to be a predictive sign of hemorrhagic complications after reperfusion therapies[4, 5, 13 18]. Our study has also demonstrated that the rate of symptomatic hemorrhagic complications showed a tendency to increase as the grade of early CT signs increased, although a statically significant difference was not proved. A grade III CT sign may be a predictive sign for hemorrhagic complications after reperfusion therapy. In contrast, the presence of a grade I CT sign may not contraindicate reperfusion therapy.

本研究也显示：尽管彼此间均无统计学显著差异，但血管内再通治疗后症状性出血并发症的发生率，在深部大脑中动脉分布区未出现早期CT征象的患者、出现I级早期CT征象（细微低密度区局限于岛叶，基底节区正常）的患者、出现II级早期CT征象（部分壳核后外侧区出现低密度）的患者、出现III级早期CT征象（整个豆状核区均出现低密度）的患者中，呈逐渐增加的趋势。

objective:to investigate the therapeutic action of somatostatin in pancreatic leakage after pancreaticoduodenectomy.methods: to collect 100 patients with pancreaticoduodenectomy during 2003～2006,contrast 44 patients use somatostatin after pancreaticoduodenectomy as experimental group,and 56 patients with conventional therapy as control group.results:there were no pancreatic leakage case in the modified group of 44 cases.3 cases complicating pancreatic leakage occurd in control group,and the proportion of pancreatic leakage are different examined by statistic mathord.conclusions:use somatostatin after pd can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.

But anyway, the most important investigative procedure is the immediate clinical examination right after injury, when swelling has not appeared that much yet: If excessive mobility in the direction of supination can be made evident in contrast to the non-injured other ankle-joint, a grade - 3 - sprain will be probable.

但是无论如何，最重要的研究程序就在受伤之后是立即的临床考试，当膨胀没有仍然显得那么多的时候：如果 supination 的方向过度的可动性能被做显然相反非者伤害了其他的脚踝-关节，等级- 3-扭伤将会是可能的。

Based on pre-experiment foundation of the earlier period, 60 male patients among 45-65 year old were chosed as the clinical case according to the PADAM diagnosis standard, and were divided into 3 groups according to the block stochastic principle, the observation group (acupuncture combined with BUSEHN capsule), group 1, group 2 (takes orally BUSEHN capsule group), each group had 20 cases, and each group of patients was measured by the method of radio-immunity for the serum level of testosterone, luteinizing hormoha, follicle-stimulating hormone before and after the treatment. By the contrast of the grade of PADAM symptom among three groups before and after treatment ,we can reveal the whole funcamental characteristic of acupuncture combined with herb ,and discuss a new way to enhance the curative effect of acupuncture ,and summarize the endocrinous adjustment of acupuncture for the PADAM's patients and the orchidic improvement by the treatment of acupuncture.

在前期预实验的基础上，选择符合诊断标准的PADAM诊断标准的45-65岁男性患者临床病例60例，按照区组随机原则分为3组，观察组、对照组1、对照组2，每组各20例，采用放射免疫法分别测定各组患者治疗前后血清中血清睾酮、黄体生成素、卵泡刺激素的血清浓度的水平；通过三组及三组间治疗前后PADAM症状评分指数的对比研究，揭示针药结合的整体调节作用特色，探讨提高针灸疗效的新途径；总结出针刺对中老年雄激素缺乏综合征患者的内分泌的调节及针刺对睾丸的改善程度，探讨针药结合治疗本病的机制及针灸增效剂的应用前景，为今后进一步研究打下坚实基础。

Nevertheless, even if the affected bowel loops at the abnormal anatomic location are not dilated and small internal hernias with low-grade obstruction are detected, we recommend that surgical colleagues use appropriate care to decrease hernial strangulation. Examples of such care include carefully monitoring the patient's vital signs and physical examination results or performing follow-up CT or gastrointestinal studies enhanced with intraluminal contrast material, including CT enteroclysis.

尽管处于异常解剖部位的受累肠管没有扩张，腹内疝较小，梗阻程度较轻，我们也推荐外科同事给予适当的护理减小疝性绞窄，例如详细的监护病人生命体征、进行体格检查、复查CT、使用管腔内造影剂的胃肠增强检查，包括CT肠造影术。

In contrast, when grade III CT signs were present, all of the lenticulostriate arteries were involved in ischemia.

In contrast, 10 (90.9%) of 11 cases contained nonsynonymous TP53 mutations characteristic of high-grade serous carcinomas.

相反，其中10例（90.9%）却发生了TP53基因的非同义突变，此突变是高级别浆液性癌的特征。
