Objective To compare the safety and efficacy of intravenous thrombolysis for patients with acute cerebral infarction in a second-grand class-A hospital and a third-grand class-A hospital. Methods Twenty-one consecutive patients with cerebral infarction treated with alteplase for intravenous thrombolysis were enrolled in a second-grand class-A hospital (Fengtai Hospital,Beijing)prospectively from January 2012 to December 2013 as the study group,and 65 patients in a third-grand class-A teaching hospital (Xuanwu Hospital,Capital Medical University,Beijing)admitted at the same period for intravenous thrombolysis were used as a control group. The differences of efficacy and safety of intravenous thrombolysis in patients of both groups were compared. The primary outcome measures were Barthel Index (BI)at day14 after onset and the modified Rankin Scale (mRS)scores at discharge. The main safety indicator was the incidence of serious adverse events (SAEs)after thrombolysis (symptomatic intracranial hemorrhage and death). Results (1 )In the primary outcome measures,the proportions of mRS≤2 at discharge in the study group and the control group were 71. 4%(n=15)and 58. 5%(n=38)respectively. At day 14 after thrombolysis,the proportions of BI ≥60 were 61. 9%(n=13)and 64. 6%(n=42)respectively. There were no significant differences between the two groups (P>0. 05). (2)The incidences of the primary serious adverse events were 4. 8%(n=1)and 6. 2%(n=4). There was no significant difference (P>0. 05). Other secondary outcome measures,such as the early reperfusion rate,recanalization rate,and the proportion of neurological improvement at day 14 after thrombolysis and the overall incidence of cerebral hemorrhage had no significant differences. The case referral proportion (9. 5%,n=2)of the study group had a trend of lowering than the control group (27. 7%,n=18)P=0. 09. (3)The out-hospital time delay, in-hospital time delay,and overall time delay of the study group were less than those of the control group, and the mean time was 75 ± 33 vs. 102 ± 50 min,and 72 ± 41 vs. 111 ± 38 min,147 ± 41 vs. 212 ± 47 min. There were significant differences (P<0. 01). Conclusion The second-grand hospital selected by our study can relatively safely and effectively perform intravenous thrombolysis for acute cerebral infarction with alteplase. Moreover,the intravenous thrombolysis of the second-grand hospitals may reduce the case referral ratio and visiting time.

Chinese Traditional and Herbal Drugs 2015;46(3):401-404
Objective: To observe the clinical efficacy of Shenqi Fuzheng Injection (SFI) combined with chemotherapy in the treatment of acute myeloid leukemia (AML) and the effect on body's immune function, and to explore the function and mechanism of adjuvant chemotherapy with SFI. Methods: One hundred and twelve patients were divided into two groups: the treatment group (n = 54) treated with DA protocol plus SFI and the control group (n = 58) treated with DA protocol alone. We observed the remission rate, mortality, the time of myelosuppression, the changes of T lymphocyte subsets; and the side-effects of chemotherapy for the patients in the two groups. Results: Comparing the remission rate and mortality rate of the patients between the two groups, there was no statistically significant difference (P > 0.05). The side-effects of the patients in the treatment group were more significantly reduced than those of the patients in the control group (P < 0.05), with the shorter time of myelosuppression (P < 0.05), more CD3+/CD4+ cells, and higher cell rates of CD4+/CD8+ (P < 0.05). Conclusion: The SFI could shorten the time of myelosuppression induced by the chemotherapy in the treatment of AML, regulate the level of T lymphocyte subsets, enhance the active immune function of body, and reduce the relative side-effects of chemotherapy.

Neurofeedback, as an alternative treatment method of behavioral medicine, is a technique which translates the electroencephalogram (EEG) signals to styles as sounds or animation to help people understand their own physical status and learn to enhance or suppress certain EEG signals to regulate their own brain functions after several repeated trainings. This paper develops a neurofeedback system on the foundation of brain-computer interface technique. The EEG features are extracted through real-time signal process and then translated to feedback information. Two feedback screens are designed for relaxation training and attention training individually. The veracity and feasibility of the neurofeedback system are validated through system simulation and preliminary experiment.

Objective: To study if there is an aryl-hydrocarbon receptor (AHR) expression in patients of pulmonary arterial hypertension associated with congenital heart disease (CHD-PAH) and to explore if the amount of AHR expression related to pulmonary vascular remodeling.
Methods:A total of 32 CHD-PAH patients diagnosed by echocardiography and right heart catheterization for surgical repair were enrolled, and the lung tissue biopsy was performed during the operation. The pulmonaryAHR was detected by immunolfuorescence assay, the ratios of vessel wall area/total area (WA/TA) and vessel wall thickness/vessel external diameter (WD/TD) of small pulmonary arteries were calculated with the imaging software, the mRNA expression of AHR, hypoxia-inducible factor-1α (HIF-1α), aryl-hydrocarbon receptor nuclear translocator (ARNT) and vascular endothelial growth factor (VEGF) were examined by RT-PCR. In addition, blood level of AHR was measured by ELISA.
Results: There was AHR expression in pulmonary tissue in all 32 patients. And AHR mRNA expressions were positively related to mPAP (r=0.809,P<0.001), WA/TA (r=0.723,P<0.001), WD/TD (r=0.746,P<0.001); and positively related to mRNA expressions of HIF-1α (r=0.889,P<0.001), ARNT (r=0.738,P<0.001), VEGF (r=0.822,P<0.001). Pulmonary tissue VEGF mRNA expressions were positively related to mPAP (r=0.739,P<0.001), WD/TD (r=0.702,P<0.001) and WA/TA (r=0.657,P<0.001). Blood levels of AHR were positively related to mPAP (r=0.754,P<0.001), WD/TD (r=0.754, P<0.001) and WA/TA (r=0.739,P<0.001).
Conclusion: AHR might be involved in pulmonary vascular remodeling in CHD-PAHpatients.
