bvm

Results Significant differences were observed between BVM and SHD groups in dry weight, ultrafiltration volume, post-hemodialysis blood pressure, acute complications and nursing intervention, while no significant difference in pre-hemodialysis blood pressure.

结果两组透析前的血压比较没有统计学意义，血容量监测组的干体质量、脱水量、透后血压、急性并发症及护理干预次数与标准血液透析组相比均有显著性差异。

Objective To evaluate the efficacy of blood volume monitoring ( BVM) on adjusting dry weight accurately during hemodialysis.

目的探讨在血透过程中利用在线血容量监测技术准确调整干体重的可能性。

BVM ( Ball Vector Machine) is a faster machine learning algorithm than SVM.

球向量机是一种比SVM更快的机器学习方法。

Methods Ten cases of BVM ( 8 male and 2 female, average age 34.4 years) were diagnosed by CT and MRI showing the lesions in pons 6 cases, in pontomesencephalic junction 3 cases and in pontomedullary junction 1 case.

方法对10例脑干血管畸形患者进行回顾性分析，男8例，女2例；平均年龄34.4岁。

Results: ① The levels of BVH, BVM, BVL, capillary plasma viscosity and erythrocyte sedimentation rate ( ESR) in ICP group were significantly higher than those in normal group ( P all < 0.05, BVH P < 0.005);

结果：①ICP组高切、中切、低切、毛细血管血浆粘度、血沉均显著高于正常妊娠组（均P<0.05，其中高切P<0.005）；

Hemorrhage was the most common clinical manifestation and main cause of death in BVM.

脑出血是脑血管畸形最常见的临床表现，并系引起死亡的主要原因。

Objective The surgical treatment, approaches and result in ten patients with brain stem vascular malformation ( BVM) was reported.

目的探讨脑干血管畸形的外科治疗方法、手术入路和治疗效果。
