Soft tissue myxoma is a benign neoplasm arising from fibroblasts that produce an excessive amount of mucopolysaccharide.

Methods Three types of dissection of facial nerve were used in parotidectomy of 156 cases, exposing main trunk of facial nerve, exposing mandibular marginal branch, exposing peripheral branches.

腮腺良性肿瘤156例，分别用面神经主干解剖法，面神经下颌缘支解剖法，面神经前部分支解剖法解剖面神经并切除肿瘤及腺体，统计面瘫发生率并统计学处理。

Methods One hundred and eleven serum samples were collected, including 30 small RCC cases, 34 renal benign mass cases and 47 healthy persons.

收集了111例血清标本，分别为小肾癌患者30例，肾脏良性肿瘤34例，健康人47例。

For benign tumors of the neck and body of the pancreas, enucleation or central pancreatectomy is the reasonable surgical option.

Operation is the most effective way to treat PRT.

手术是治疗腹膜后肿瘤最有效的办法，本组良性肿瘤切除率为87%，恶性肿瘤切除率为51%。

Results Among the 86 cases of PRT, 62 were malignant tumor and 24 benign tumor.

结果 86例中恶性肿瘤 6 2例，肿瘤完整切除率 5 9%，合并脏器切除率 5 8.1%；良性肿瘤 2 4例，肿瘤完整切除率 79.2 %，合并脏器切除率 8.3%。

Results 33 cases of benign PRT, 51 malignant PRT and 1 borderline tumor were diagnosed by operation and postoperative pathologic examination.

结果良性肿瘤33例，恶性肿瘤51例，交界性肿瘤1例，均经手术治疗且病理证实。

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。
