Objective To observe the changes of malondialdehyde (MDA), superoxide dismutase (SOD-1) in serum and plasma endothelin (ET)and angiotensin II(AⅡ) in patients with severe closed head injury before and after being treated with hyperbaric oxygenation (HBO). Methods Fifty patients were recruited. Thirty-two patients were treated with HBO in addition to the conventional management (HBO group) and the other eighteen patients without HBO except for conventional management served as the controls (control group). Thirty healthy volunteers served as normal controls (normal group). Activities of MDA ,SOD-1,ET and AII were measured with spectrometry and radioimmunoassay in all the subjects, respectively, during the study. Results Before treatment, there was a significant difference between the normal group and HBO group as well as the control group in regard to the activities of the 4 parameters(P0.05) as the 4 parameters were concerned. The patients scored 3-5 with GCS in the control group were significantly different from those scored the same with GCS in the normal group in terms of the SOD-1 and MDA. Higher GCS was found in patients with low activities of MDA, ET and AII but high SOD-1 levels. Favourable changes of GCS and GOS were observed in patients in the HBO group as compared with those in the control group (P

Objective:To investigate the influencing factors for orthostatic hypotension(OH)in elderly patients with hypertension.Methods:This was a case-control study.A total of 224 patients with hypertension aged over 65 years were included.After resting for more than 5 minutes, subjects had their blood pressures measured in the supine and standing position at 0 min, 1 min, 2 min and 3 min.OH was defined as a fall in systolic BP of more 20 mmHg(1 mmHg=0.133 kPa)and/or diastolic BP below 10 mmHg of baseline within 3 min in the upright position.Subjects were divided into the OH group( n=34)and the non-OH group( n=190). Baseline data, comorbidities and differences in medications were compare between the OH group and the non-OH group, and the influencing factors for OH were analyzed. Results:The proportion of drinkers was higher in the OH group than in the non-OH group(29.4% or 10/34 vs.7.4% or 14/190, χ2=14.649, P<0.01). Both systolic pressure(139.0±22.1 mmHg vs.124.5±16.3 mmHg, t=-3.661, P<0.01)and diastolic pressure(77.6±6.3 mmHg vs.69.2±9.0 mmHg, t=-6.696, P<0.01)in the supine position were higher in the OH group than in the non-OH group.The proportions of patients with diabetes(47.1% or 16/34 vs.25.3% or 48/190, χ2=6.731, P<0.05)and stroke(41.2% or 14/34 vs.24.2% or 46/190, χ2=4.233, P<0.05)were higher in the OH group than in the non-OH group.The proportion of patients receiving α receptor blockers was higher in the OH group than in the non-OH group(23.5% or 8/34 vs.4.2% or 8/190, χ2=16.228, P<0.01). After adjusting for factors such as alcohol consumption, diabetes, stroke and other differences between the OH and non-OH group, logistic regression found patients with alcohol intake( OR=5.274, 95% CI: 1.990~13.982, P<0.01), diabetes( OR=2.744, 95% CI: 1.213~6.208, P<0.05)and using α receptor blockers( OR=8.812, 95% CI: 2.835~27.383, P<0.01)had a higher risk of OH. Conclusions:OH is very common in elderly patients with hypertension.Alcohol consumption, diabetes mellitus and the application of α receptor blockers can increase the risk of OH.
