Apart from the classic triad of hypokinetic gait disorder, cognitive dysfunction and urinary incontinence, the clinical spectrum of normal pressure hydrocephalus has been found to affect the upper limbs. It is unclear if the motor deficit of hand and arm movements improves with CSF evacuation. The present study was designed to quantitatively assess the effect of CSF evacuation on the hypokinesia of grasping movements in normal pressure hydrocephalus. Eight subjects with normal pressure hydrocephalus grasped to lift an instrumented object prior to and following evacuation of 40 ml CSF. The build- up of fingertip forces and the kinematics of the lifting movement were slower for patients compared with healthy controls. Patients also generated excessive grasping forces when lifting and holding the object stationary prior to and following CSF evacuation. CSF evacuation significantly improved the gait disorder, the cognitive impairment and the urinary incontinence in normal pressure hydrocephalus. CSF evacuation accelerated the lifting movement and reduced the grip force overshoot. These data suggest that the measurement of grasping forces may provide an additional test to quantify the clinical response to CSF tapping in normal pressure hydrocephalus.

公元1403年,燕王朱棣取得皇位,随后决定迁都北平,并在元大都基础上重建北京城。此后的正统、嘉靖、隆庆年间都曾对北京城的城墙及其他建筑进行过较大规模的修缮、改建。为了确保工程质量,朝廷采取了一系列的严厉措施。  “实名制”便于“倒查”  兴建北京城时,永乐皇帝效仿明太祖修建南京城的做法,令烧制砖瓦的官窑、私窑在砖瓦的侧面或背面刻上窑场的字号及生产年份,有的还刻上窑主和监工的名字,如“××窑/窑匠×
