Application of Six-minute Walk Test in Acute Stroke Patients / 中国康复理论与实践

Objective To apply Six-minute Walk Test (6MWT) in acute stroke patients and analyze the results. Methods From Novem-ber, 2014 to January, 2015, 29 acute stroke patients with multiple or single infarction accepted 6MWT. The distance, distance per minute, blood pressure and heart rate before and after test, adverse events or discomforts during the test were recorded. Weak and fatigue scores were calculated. Results The mean of distance in acute stroke patients was (240.1±17.2) m, that was (46.8±3.3)%of the predicted values in the healthy. Male patients walked (255.4±21.40) m, not different from (214.9±28.4) m in female (t=-1.151, P=0.26). The distance liked to be negatively correlated with age (r=-0.356, P=0.058). The distance was similar in each minute. Weak score was (46.8±3.3)%, fatigue score was mostly between-20 and 20, and no correlation was found between them. Blood pressure and heart rate increased significantly at the end of the test (t>2.476, P<0.05). Few of patients complained mild discomforts. Conclusion 6MWT is safe and suitable for acute stroke patients for physical mobility judgement, but adverse events need to be cared.

Expression and significance of Gab2 in colorectal cancer tissues / 中国免疫学杂志

Objective:To investigate the expression and significance of Gab 2 in colorectal cancer tissues .Methods:Immuno-histochemistry was used to detect the expression of Gab 2 in 78 cases of colorectal cancer tissues and 46 cases of the adjacent tissues and to analyze the association of Gab2 expression with the clinicopathologic features of colorectal cancer;The expression of Gab2 in samples from 10 cases of colorectal cancer tissues and matched adjacent nontumorous tissues was detected by Western blot .Results: The results of immunohistochemistry demonstrated that the Gab 2 protein positive expression rate in 78 cases of colorectal cancer was 53.85%;whereas was negative expression or weak in the adjacent tissues , showing a significant difference of comparison within this result (P0.05) .Western blot showed that the Gab2 protein expression of colorectal cancer cases was significantly higher than that of matched adjacent nontumorous tissues ( P<0.05 ).Conclusion: Gab2 was overexpressed in colorectal cancer .Gab2 maybe play an important role in carcinogenesis and progression of colorectal carcinoma .
