Objective To observe effect of scalp acupuncture combined with cognitive rehabilitation training in ameliorating cognitive dysfunction in stroke patients. Methods Eighty-four stroke patients with cognitive dysfunction were randomly divided into a treatment group ( n = 42) and a control group (n = 42 ) . All of the patients in both groups received routine therapy including cognitive rehabilitation training by professional therapists aimed at improving their orientation, perception, attention and thinking. The patients in the treatment group also received prolonged scalp acupuncture, in which the acupuncture needle remained in the scalp for 6 hours. All cases were evaluated using Loewenstein's occupational therapy cognition assessment (LOTCA) before and 10 weeks after treatment. Results The LOTCA scores were significantly different before and after treatment in both groups. The effect in the treatment group was significantly better than in the control group. Conclusions Prolonged scalp acupuncture combined with cognitive rehabilitation training can significantly improve the cognitive ability of stroke patients.

Objective To detect the microRNAs in fecal with patients of pancreatic cancer, and evaluate its diagnostic value. Methods Stool samples were collected from three group persons including 29 pancreatic cancer, 22 chronic pancreatitis and 13 normal controls. The total fecal microRNAs were extracted.The quantity of miR-16, miR-21, miR-155, miR-181a, miR-181b, miR-196a, and miR-210 were detected by using real-time PCR, and miR-16 was used as reference gene. ROC AUC was used to evaluate the diagnostic value for pancreatic cancer. Results MicroRNAs were efficiently obtained from stools, and independent experiments showed high reproducibility for microRNAs extraction and detection. The expression of miR-181b,miR-196a, miR-210 in fecal was 2.22 ±0.64,2.78 ±0.14, 5.55 ±0.38 in pancreatic cancer; 1.42 ±0.39,3.88 ± 0.85,5.39 ± 0.69 in chronic pancreatitis; 0.32 ± 0.40, 1.14 ± 0.98,4.23 ± 0. 99 in normal controls;the three microRNA expressions in pancreatic cancer were group and CP group significantly higher than those in normal controls ( P < 0.05 ). But there was no significant difference between pancreatic cancer group and chronic pancreatitis group. AUC of pancreatic cancer / normal controls miR 18lb was 0.745(95% CI 0. 597-0.894), the sentivity, specificity for pancreatic cancer was 84.6% and 51.7%. AUC of miR-210 was 0. 772(95% CI0.629-0.914), the sentivity, specificity for pancreatic cancer was 84.6% and 65.5%, and the difference was statistically significant (P <0.05). miR-196a was no significant for the diagnosis of pancreatic cancer, but the expression of miR-196a was correlated with the tumor size (r = 0.516, P = 0.041 ).Conclusions The extraction and detection of the fecal microRNAs were non-invasive and reproducible. The expression of miR-181b and miR-210 was increased in stool of patients with pancreatic cancer, and may be potential biomarker for pancreatic cancer.
