ABSTRACT

Objective To design a high performance and low power consumption ECG signal acquisition system which can meet the demand for long time monitoring of the physiological status of patients.Methods The prototype system utilized low power ECG analog front end ADAS1000 and MSP430F5529 microcontroller to achieve configuration of AFE and back-reading of ECG data by SPI bus. Results This system implemented 24-hour dynamic ECG monitoring of patients in active state, and the data acquired were accurate and reliable.Conclusion The system realizes PCB integration, low power consumption, and can be used for battery powered portable application such as wearable devices.

ABSTRACT

Purpose:To study the clinical response and the toxic-side reactions of patients with gastric cancer treated with continuous infusion of fluorouracil (5-FU) lasting 240 hours.Methods:35 cases of gastric cancer were treated with continuous infusion of 5-FU lasting 240 hours.32 cases of gastric cancer were treated with traditional infusion of 5-FU on days 1 to 5. The clinical response and the toxic -side reactions were observed.Results:35 cases were treated with continuous infusion of 5-FU regimen with a response rate of 51.4%. 32 cases were treated with traditional infusion of 5-FU regimen with a response rate of 25.0%,thus between them,there was a significant difference in curative effects. The toxicities in traditional infusion of 5-FU group were more severe than in continuous infusion of 5-FU group. They included myelosuppression nausea et al.Conclusions:Continuous infusion of 5-FU regimen is preferable in the treatment of gastric cancer.
