Objective To explore 24-hour ambulatory blood pressure of patients with cervical spinal cord injury. Methods 42 patients with cervical spinal cord injury and 45 patients with thoracic-lumbar spinal cord injury were included. Their 24-hour ambulatory blood pressures were monitored. Their day systolic blood pressure (dSBP) and day diastolic blood pressure (dDBP) when seating and standing, night SBP and DBP, and SBP descending rate at night were compared. Results There were significant differences in dSBP and dDBP when standing, and SBP descending rate at night between 2 groups (P<0.01). There was significant difference in dSBP between seating and standing position in patients with cervical spinal cord injury (P<0.01). Conclusion There is orthostatic hypotension in cervical spinal cord injury patients and their SBP descending rate at night is upside down.

Objective To discuss the early clinical management of the pa tients with traumatic hemipelvectomy. Methods A case was reported and literature reviewed. Results The patient was a 4-year-old boy who incurred a left groin and proximal thigh crush with nearly complete transection of this extremity and arrived at our hospital 7 hours after injury. After the vital signs were stabili zed with reasonable wound care and 2 hours of fluid resuscitation, the patient r eceived a thorough debridement and the hip disarticulation and fixation of pubic symphysis. The postoperative course was relatively smooth. While the successful treatments of this patient corresponded to the experiences in the literature, s pecial considerations regarding this severe injury were discussed. Conclusion Im mediate prehospital hemostasis by local pressure, rapid transport, aggressive in itial resuscitation, early recognition of the severity and prompt decision to co mplete the amputation, and attention to details in the rehabilitation phase are necessary for successful management of these patients.

Objective To find out the factors affecting the outcome of severe acute respiratory distress syndrome (ARDS) patients treated with extracorporeal membrane oxygenation (ECMO).Methods From November 2008 to September 2010,patients with severe acute respiratory distress syndrome (ARDS) required extracorporeal membrane oxygenation (ECMO) after failure of conventional therapy were retrospectively studied.Patients treated by veno-arterial ECMO,treated by mechanical ventilation for more than l0 days were excluded.All patients were divided into survival group and non-survival group,according to the 28 day survival situation after ECMO treatment.We compared the clinical data of the two groups when transferred to Intensive Care Unit (ICU),before and after ECMO treatment.We used Independent-samples t test and Chi-square tests to find out the factors affecting the results of ECMO treatment in the patients with severe ARDS.Results A total of twenty-five patients were enrolled in the study,of whom 15 patients survived,10 patients died.The results showed that the average age of the survival group is lower than that of non-survival group (49.8 ± 10.5) vs.(59.9 ± 11.5),P =0.044,and the proportion of patients with severe ARDS caused by Influenza A (H1 N1) in the survival group was higher than that of the non-survival group (x2 =4.453,P =0.048).In addition,the duration of mechanical ventilation before ECMO treatment in the survival group was shorter than that in the non-survival group (57.8 ± 8.7) hours vs.(68.3 ±13.7) hours,P =0.013.Conclusions The age,pre-ECMO ventilation duration and the cause of ARDS are the important factors influencing the efficacy of ECMO treatment in the patients with severe ARDS.

Objectives To explore the effects of hemodialysis on oxidizing stress and plasma nitrogen monoxide (NO) levels in maintenance hemodialysis patients. Methods 67 maintenance hemodialysis patients (male 39, female 28, and mean age 58?13y) were enrolled in this study. Serum malondialdehyde (MDA) level was measured by colorimetry, and plasma NO level was determined by enzymatic method. The MDA and NO levels before and after hemodialysis were measured in 48 cases of the patients. Results After hemodialysis, the serum MDA levels significantly increased, and the plasma NO levels decreased. The patients with cardiovascular diseases had lower NO levels and higher MDA levels than the patients without ones before hemodialysis. The serum MDA levels of the patients using biological incompatible dialysis membrane increased after hemodialysis. Conclusion Hemodialysis treatment, especially using biological incompatible dialysis membrane increased oxidizing stress and decreased plasma NO levels in maintenance hemodialysis patients, and was significantly correlated with the pathogenesis of cardiovascular diseases.
