Objective To investigate hospital admission time of acute stroke patients and its influential factors.

Objective To evaluate the influence of a clinical pathway on mean length of hospital stay of ischemic stroke patients.

Objective To compare hyponitrogenic/hypocaloric parenteral nutrition and t ra ditional parenteral nutrition via periphery vein on blood glucose?infection rel ated complications,hospital stay and cost.

Objective: To investigate the characteristics of the costs in stroke patients received standard tertiary rehabilitation, the relationship of the initial stage functional comprehensive assessment(FCA) scores with the costs of major items and length of stay(LOS).

Objective:To study the characteristic of the hospital costs in rehabilitation of patients with stroke, costs of major resource items were compared and the relation of the hospital costs and length of stay and function measure scores (BI, FIM, STREAM) were studied.

Then the time of getting warm,length of stay and incidence of complications in premature infants between the two groups were compared.

The simulation experiment shows that the shorter teeming time is,the less air entrainment of tapping is;the lower teeming height is,the less air entrainment of tapping is.
