The remediation effect was verified under the conditions that the electric field strength was 2 V/cm, 0.1 mol/L citric acid was used as the electrolyte, and the remediation reaction time was 96 h. The results showed that for the approaching anode method, when the average electromigration distance was 5.48, the removal rate was 88.12%, which was 10.47% higher than the unenhanced technique, and the energy consumption per unit volume was 7.36 kWh/m^3;and as to the intermittent current method, the removal rate was 80.81%, and the energy consumption per unit volume was 8.12 kWh/m^3, which was relatively reduced by 33.07%. After the remediation, the proportions of the weak acid extractive form and reducible form of calcium decreased, and the proportions of the oxidizable form and residual form of cadmium did not change significantly.展开更多

We then conducted intermittent time series analysis on pharmaceutical costs. After the implementation of clinical pathway, overall pharmaceutical costs of patients with transient ischemic attack reduced significantly. The effect was not significant for cerebral hemorrhage patients. The implementation of clinical pathway has a desirable outcome on controlling pharmaceutical costs.展开更多
