良性肿瘤

Objective To investigate the diagnosis and treatment of benign renal neoplasms.

Results In 46 cases, there were 4 parotitis, 26 benign tumors, and 16 malignant.

结果46例患者中，慢性炎性肿块4例，良性肿瘤26例，恶性肿瘤16例。

In this study, although the quantity of the scatter power can not reflect the content of blood flow, the scattered power variance is statistically significant between benignancy and malignancy （p=0.014 , sensitivity=80%, specificity 64%）. However, the PW Var does not have sufficient statistical significance in differentiate the normal tissue perfusion from the malignant one.

另外 Power Doppler的功率强度在整个实验的比较结果，虽然并不能证明与血流量、压力波有直接的关连，但是恶性肿瘤的功率强度的变异量均明显高於良性肿瘤（P=0.014 Sensitivity=80% Specificity 64%），不过恶性肿瘤却与正常组织无法区分。

Results Among the 96 cases,54 were benign,20 were borderline,and 22 were malignant.

结果 96例中良性肿瘤 54例( 56.2 5%)，交界性肿瘤 2 0例( 2 0 。83%)，恶性肿瘤 2 2例( 2 2 。92 %)。

Objective To deepen the understanding of primary benign tumors of trachea and bronchus for increasing the diagnosis early.

目的 加深对原发性气管支气管良性肿瘤的认识，提高早期诊断率。

Experts note cancer is a complex disease, caused by the interaction of possibly hundreds of genes and the environment.

研究者称，这种变异一般似乎出现在肿瘤发育的晚期，即良性肿瘤向恶性转变的时期。

Local mesenteric lymphadenopathyis also often present in cases of mesenteric panniculitis ( Figs 18,19). These findings are nonspecific, and the differentialdiagnosis includes carcinomatosis, lymphoma, carcinoid tumor,and desmoid tumor.

局部肠系膜淋巴结病常出现在肠系膜脂膜病（图18，19），这种表现没有特异性，鉴别诊断包括，癌症，淋巴瘤，良性肿瘤，和纤维性肿瘤。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
