OBJECTIVE： To observe the relationship between the levels of glutathione （GSH） and malonaldehyde （MDA）, the metabolite of lipid peroxidation, in erythrocyte and deformation index of erythrocyte in patients at various periods following acute cerebral infarction. DESIGN： Controlled observation.SETTING： Qilu Hospital of Shandong University and Institute of Cerebrovascular Disease of Qingdao Medical College. PARTICIPANTS： We chose 98 inpatients with acute cerebral infarction from Department of Neurology, Qilu Hospital of Shandong University from January to December 2000 , serving as cerebral infarction group, including 50 male and 48 female, with mean age of （62±7）years. There were 23 cases found on the 1^st day after onset; 25 cases on the 3^rd day after onset; 25 cases on the 7^th day after onset; 25 cases on the 14th days after onset, and they were all confirmed by craniocerebral CT or MRI. Another 30 homeochronous inpatients with neurosis, cervical syndrome, lumbar intervertebral disc herniation and motor neuron disease were chosen as control group, including 20 male and 10 female, with mean age of （52±8）years . There was no significant difference in age and gender distribution between two groups （P 〉 0.05）. Patients in the two groups were informed of detected index.METHODS：①Ulnar venous blood was chosen from the patients who were fasted on the 1^st, 3^rd,7^th and 14^th days after onset. Deformation index of erythrocyte was measured with BL88-CKX laser diffraction erythrocyte deformeter and photographing was performed. GSH level in erythrocyte was measured with DTNB assay introduced by Beu-tler. MDA level in erythrocyte was measured with modified thiobarbituric acid colorimetric method.②At each sample collecting , according to the criteria accepted by the Fourth National Conference of Cerebrovascular Disease, intergrant of neurologic impairment 〈 15 points was regarded as mild （n=46）, 15 to 30 points as moderate （n=40）and, 〉 30 points as severe （n=12）. ③ t test was used to compare data between two groups , and linear correlation analysis was used in relationship analysis among indexes. MAIN OUTCOME MEASURES ：① Comparison of erythrocyte GSH and MDA levels and deformation index of erythrocyte at various periods between patients with acute cerebral infarction and controls. ②Correlation of erythrocyte GSH level with erythrocyte MDA level and with deformation index of erythrocyte in patients with cerebral infarction . ③ Relationship between erythrocyte GSH level and severity of disease in patients with acute cerebral infarction. RESULTS： Totally 98 patients with acute cerebral infarction and 30 controls all entered the stage of result analysis. ① Erythrocyte GSH level and deformation index of erythrocyte were lower on the 1^st, 3^rd, 7^th and 14^th days after onset in cerebral infarction group than in control group （P 〈 0.05-0.01）, and erythrocyte MDA level was significantly higher in cerebral infarction group than in control group （P 〈 0.05-0.01）. The three indexes changed most significantly on day 3 after onset in patients, and began to recover or decrease on day 7 after onset and inclined to be normal on day 14 after onset. ② Erythrocyte GSH level was significantly negatively correlated with erythrocyte MDA level in patients with acute cerebral infarction on the 1^st, 3^rd, 7^th and 14^th days after onset （r=-0.534, -0.713, -0.645, -0.656, respectively, P 〈 0.05-0.01 ） ,and significantly positively correlated with erythrocyte deformation index （t-=0.502, 0.560, 0.455, 0.504, respectively, P 〈 0.05）. ③Erythrocyte GSH level was significantly lower in moderate or severe patients with acute cerebral infarction than in mild patients[（0.215±0.088）,（0.192±0.102）, （0.281±0.090） g/L, P〈 0.05]. CONCLUSION：①Erythrocyte GSH and MDA levels and deformation index of erythrocyte change significantly on the 3^rd day following acute cerebral infarction. Index detection results gradually tended to be normal on from the 7^th day to 14^th days day after onset. ② Change of erythrocyte GSH level can reflect the severity of disease of patients with acute cerebral infarction.③Decrease of erythrocyte GSH level in patients with acute cerebral infarction is one of reasons that result in the decrease of deformation ability of erythrocyte.展开更多

Methods: Seventy-six cases of hemiplegia patients with ischemic stroke were divided into the treatment group and the control group(n=38 in each). Based on the Brunnstrom's stage of Xingnao Kaiqiao acupuncture combined with rehabilitation training was used in the treatment group, and the control group was given rehabilitation training. FuglMeyer Assessment of the upper extremity(FMA-UE), Action Research Arm Test(ARAT) and Simple Test for Evaluating hand Function(STEF) were adopted separately to compare scores before treatment and 8 weeks after treatment. Results: The difference was not statistically significant in the two groups of patients for comparison of FMA-UE, ARAT and STEF scores before treatment(P>0.05). The difference was statistically significant in the two groups of score comparison of FMA-UE, ARAT and STEF after treatment(P<0.05). Conclusion: The Xingnao Kaiqiao acupuncture has its unique advantages in improving recovery of motor function of upper limb and hand in recovery period after stroke.展开更多

In the present study, we reported a 69-year-old right-handed female patient with an infarct in the mid to lateral portion of the left cerebra peduncle, who showed an aberrant pyramidal tract by diffusion tensor tractography. The patient presented with severe weakness of the right extremities at stroke onset. The patient showed progressive motor recovery as much as being able to extend the affected extremities against some resistance at 6 months after onset. At 20 months after stroke onset, motor function of the left extremities had recovered to a nearly normal state. Diffusion tensor tractography results showed that the PT was disrupted at the lower midbrain of the affected （left） hemisphere at 3 weeks after stroke onset and this disruption was not changed at 20 months. An aberrant pyramidal tract in the left hemisphere was also observed, which originated from the primary motor cortex and descended through the corona radiata, posterior limb of the internal capsule, thalamus, the medial lemniscus pathway from the midbrain to the pons, and then entered into the pyramidal tract area at the pontomedullary junction. Transcranial magnetic stimulation did not elicit motor evoked potential from the affected hand muscle at 3 weeks, but it elicited motor evoked potential with mildly delayed latency and low amplitude in the affected hand muscle at 20 months. The main motor functions of the affected extremities in this patient appeared to be recovered via this aberrant pyramidal tract.展开更多
