Objective:To evaluate the psychosomatic effects of relaxation and the correlation between the effects and the personality and behavior pattern of the subject.Methods:68 medical students were involved in the study. All the subjects received relaxation training for 2 months. They were tested with Self-Rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) before and at the end of the study. They were also tested electroencephalogram (EEG), electromyography (EMG) and skin temperature at the above two time-points. The correlation between the personality and the extents of alteration in index of EEG were also studied.Results:After training, the scores of SAS and PSQI in the subjects were significantly lower than those before training. The indexes of EEG, EMG and skin temperature were improved. The extents of alteration in index of EEG were correlated positively with the N-scores of Eysenck Personality Questionnaire (EPQ), the total scores and TH-scores of Type A Behavior Pattern (TABP).Conclusion:Relaxation can improve psychosomatic states of undergraduates. The extents of alteration in index of EEG were correlated with the personality and behavior pattern of the subject.

BACKGROUND: The curative effect is satisfactory for adult patients with spasticity of lower limbs treated with selective posterior rhizotomy and peripheral nerve micro diminution. But how to improve the strength of relevant muscle is the key factor to accelerate recovery of motor function during rehabilitation training.OBJECTIVE: To observe the effect of muscle stimulating instrument on the recovery of muscle strength and the improvement of motor function of adults with spasticity of lower limbs during rehabilitation training.DESIGN: Case analysis.SETTING: Department of Neurosurgery, China-Japan Friendship Hospital of Beijing Ministry of Public Health.PARTICIPANTS: Totally 49 adults with spasticity of lower limbs were selected from Department of Neurosurgery, China-Japan Friendship Hospital of Beijing Ministry of Public Health from January 2000 to May 2002.There were 37 males and 12 females aged from 19-48 years. Totally 21patients treated with muscle stimulating instrument were determined as treatment group and other 28 patients were determined as control group during rehabilitation training.METHODS: One day after operation, conventional rehabilitation training was performed on patients in the treatment group and the control group.Patients in the treatment group were also treated with muscle stimulating instrument three times a day with each for 30 minutes for totally 7 days as a course. There was a three-day interval between treating courses and the rehabilitative time lasted for 6 months. Before rehabilitation training, indexes of patients in the two groups, such as ankle extension, knee flexion and muscle strength of thigh adductor, were recorded and the improvement of muscle strength after 3 and 6 months was followed up.MAIN OUTCOME MEASURES: Average strength of relevant muscle before and after 3-month and 6-month rehabilitation training.RESULTS:Totally 49 patients entered the final analysis.①After 3-month and 6-month treatment, indexes of ankle extension, knee flexion and muscle strength of thigh adductor were increased at various degrees.②During 3-month and 6-month treatment,indexes of ankle extension,knee flexion and muscle strength of thigh adductor in the treatment group were obviously higher than those in the control group [3-month treatment:(4.2±0.8), (3.7±0.7) degrees; (4.3±0.7), (3.8±0.7) degrees; (4.0±0.7), (3.5±0.5)degrees; 6-month treatment: (4.5±0.6), (3.9±0.7) degrees; (4.6±0.7), (4.0±0.5)degrees; (4.4±0.7), (4.0±0.6) degrees, (P ＜ 0.05 or P ＜ 0.01)].CONCLUSION: The combination of rehabilitation training and muscle stimulating instrument can accelerate the recovery of muscle strength and motor function in adults with spasticity of lower limbs after microsurgical treatment.

Objective To observe the effect of Huahongjiangxiantang on hemorheology and plasma fibrinogen (FIB).Methods 100 patients with hypertension were randomly divided into two groups:the treatment group ( n=50) which were treated with Huahongjiangxian-tang,and the control group( n=50)were treated with Aspirin.Hemorheology and plasma fibrin were detected before and after treatment for 8 weeks.Results After 8 weeks treatment,there were significant depressions in whole blood viscosity(low shear rate),RBC deformability index and RBC aggregation index( P＜0.01 ),and better than the control group( P ＜0.05 ).There were significant changes in whole blood viscosity ( high shear rate),plasma viscosity,RBC rigidity index and plasma fibrin ( P ＜ 0.05 ).A number of indicators declined significantly in control group ( P ＜ 0.05 );The rate of platelet aggregation to improve the situation in the control group was better than that of the treatment group,but there was no statistical significance.Conclusion Huahongjiangxiantang can effectively reduce blood viscosity in patients with hypertension and improve the body's red blood cell function and fibrinolysis,benefit to the prevention and treatment of atherosclerosis and reduce the occurrence of thrombotic events.

Objective To investigate the effect of ketamine on the expression of HSP 70 in myocardium in severely burned rats for its possible mechanism of myocardial protection. Methods Seventy-two male Wistar rats were randomly divided into 3 groups: normal control group (group C, n=8), burn injury group (group BI, n= 32) and ketamine group (group K,n=32). 30% Wtal body surface area of Ⅲ degree burn model was developed in group BI and group K. Ketamine 20 mg/kg was injected IM in group K 15 min after the burn model was made. Equal volume of normal saline was given instead of ketamine in group BI. Group C received no treatment. The rats were sacrificed at 3, 6, 12 and 24 h after administration in group BI and group K respectively(8 rats at each time point). Myocardial samples were obtained for determination of the expression of HSP 70 by Western blot analysis. The myocardial ultrastructure was observed at 3 h after administration with electron microscope. Results The myocardial damage was milder in group K than in group BI. The expression of HSP 70 was significantly higher at 3, 6, 12 and 24 h after administration in group K and group BI than in group C(P<0.05).The HSP 70 expression was significantly higher at 3 and 6 h after administration in group K than in group BI ( P<0.05). Conclusion Ketamine can reduce the myocardial injury induced by severe burn through up-regulating the expression of HSP 70 in cardiocytes.

In recent years, the Gut Microbiota-Brain Axis theory has pointed out that there is an interaction between gut microbiota and central nervous system diseases.A number of studies have shown that there is a link between gut microbiota and depression, Parkinson's disease, and Alzheimer's disease.The association between gut microbiota and stroke has also attracted wide attention.This article reviews the association between gut microbiota and stroke.

ObjectiveTo investigate the effect of intrathecal (IT) Ro25-6981 (a selective NR2B receptor antagonist) on focal cerebral ischemia-reperfusion (I/R) injury in rats.MethodsSixty healthy male SD rats weighing 280-320 g in which IT catheter was successfully implanted without complication were randomly divided into 4 groups ( n ＝ 15 each):group sham operation (group S) ; group focal cerebral I/R(group I/R) ; group I/R + Ro25-6981 (group Ro) and group I/R+ normal saline (group NS).The right middle cerebral artery was occluded for 2 h with a nylon thread with rounded tip which was inserted into right internal carotid artery and advanced cranially until resistance was met in groups I/R,Ro and NS.In group Ro Ro25-6981 100 μg/10 μl was injected IT at 0,2,23 h of reperfusion,while in group NS NS was injected IT instead of Ro25-6981.Neurological dificit was assessed and scored (0 ＝ no deficit,3 ＝ severe deficit) at 24 h of reperfusion.The infarct size was determined by 2,3,5-triphenyl tetrazolium chloride staining.ResultsIT administration of Ro25-6981 significantly reduced cerebral I/R-induced infarct sized and neurological deficit score in group Ro as compared with groups I/R and NS.ConclusionRo25-6981 injected IT can protect the brain against local cerebral I/R injury.

Objective To evaluate the effect of controlled hypotension at the beginning of reperfusion on ischemia-reperfusion (I/R) injury of the liver in patients undergoing hepatectomy. Methods Forty ASA Ⅱ or Ⅲ patients aged 30-60 yr weighing 40-70 kg undergoing elective partial hepatectomy for liver cancer were randomly divided into 2 groups ( n = 20 each): group C normal BP and group H controlled hypotension. Hepatic portal was occluded during operation. In group C normal BP was maintained during reperfusion while in group H controlled hypotension (MAP was maintained at 60-70 mm Hg) was performed for 10 min since the beginning of reperfusion.Venous blood samples were taken before hepatic ischemia (T0 ,baseline) and at 15 min of ischemia (T1) and 25 min of reperfnsion (T2 ) for determination of plasma endothelin (ET), nitric oxide(NO), TNF-α and IL-1 concentrations. Results I/R of the liver led to significant increase in plasma ET, TNF-α and IL-1 concentrations and decrease in plasma NO concentration at T1,2 as compared with the baseline values at T0 in both groups. Plasma ET,TNF-α and IL- 1 concentrations were significantly lower while plasma NO concentration was significantly higher at T2 in group H than in group C. Conclusion Ten minutes controlled hypotension in the initial stage of reperfusion can attenuate I/R-induced injury to the liver in patients undergoing hepatectomy by balancing ET with NO and inhibiting inflammation response.
