Objective To detect the gastric motility in patients with type 2 diabetes mellitus, and to explore the relationship between disorder of gastric motility in diabetes and the influential factors. Methods Sixty-five patients with type 2 diabetes mellitus and 30 health control subjects were collected. The gastric motility was tested with the signal processing device designed by Chongqing University of Posts and Telecommunications. The impedance and electrical signals were collected at the same time. Fasting blood glucose (FBG) was detected by oxidation enzyme method, while microcolumn method was adopted to test HbA1c. Results In the 65 patients with type 2 diabetes mellitus,the occurrence of abnormal gastric motility was 53.85% , they had several symptoms, such as abdominal distension, early satiety, and belching. The percentage of dominant frequency of impedance gastrogram in diabetes group was lower than that in the normal controls (P<0. 05 ). The percentage of dominant frequency of EGG in the abnormal HbA1c group( ≥6. 5% ) was significantly lower than that in the normal HbA1c group ( P<0. 01). The percentage of bradygastria in the elderly was higher than that in young and middle-aged subjects (P<0. 05), respectively. Disorder of gastric motility was not correlated with FBG and course of disease. Conclusions The incidence of disordered gastric motility is very high in patients with type 2 diabetes mellitus. Elderly patients and those with higher HbA1c are prone to suffer from disordered gastric motility. However, disorder in gastric motility is not correlated with FBG and duration of the illness.
2.The measurement of anesthetic depth.
Journal of Biomedical Engineering 2009;26(1):211-215
Monitoring the depth of anesthesia (DOA) is essential for improving the quality of anesthesia and ensuring the patient's safety and rehabilitation. Monitoring DOA can increase the quality of anesthesia and the safety of operation, thus decreasing the complications caused by anesthesia. With the development of electronic and information technology, the researches for detecting DOA have made great progress. In this paper, the techniques for monitoring DOA are reviewed.

Objective To explore the effects of rehabilitation for adult cervical spinal cord injury without radiological abnormality. Methods 80 patients were studied retrospectively. Results The increase of motor score of anterior, posterior and conservative group were around 5, 2 and 2, whereas that of FIM were 11, 17 and 15, respectively. The changes of sensory score were uncertain.Conclusion The effect of surgical or conservative treatment is limited on neurological recovery, while rehabilitation can bring more functional independence to patients with cervical spinal cord injury without radiological abnormality.
