Purpose Two kinds of forward conditional reasoning including modus ponens (MP) and denial of the antecedent (DA) are the most common deductive reasoning in daily life. The present study aimed to explore the difference between the two neural machanisms. Materials and Methods Three kinds of tasks including MP, DA, and baseline were administrated to 14 undergraduates [7 males and 7 females, mean age (23.4±1.3) years] by using functional magnetic resonance imaging (fMRI) technique. fMRI data was analyzed. Results The reaction times were significantly slower for MP and DA than that of BS (P<0.001), while the effect was not significant for accuracy. In contrast to baseline, both MP and DA tasks activated the left inferior frontal cortex (BA 9), inferior parietal lobule (BA 40), and postcentral gyrus. Bilateral caudate significant activation was found in MP task when compared with DA, whereas the frontal, parietal, occipital lobe and anterior cingulate cortex were acivated more in the DA than in MP task. Conclusion Both forward conditional reasoning of MP and DA commonly activate the left frontoparietal cortex, while significant dissociations can be seen in the regions of caudate and bilateral frontal, parietal and occipital. These results firstly demonstrates the different neural mechanism underlying the two forward conditional reasoning, which might help to further uncover the brain mechanism of conditional reasoning.

Objective To observe the clinical efficacy of acupuncture at Shixuan (EX-UE11) plus rehabilitation in improving the upper-limb spasticity and hand function after cerebral stroke. Method Sixty patients with upper-limb spasm due to cerebral stroke were randomized into two groups. The observation group was intervened by conventional acupuncture plus needling Shixuan and rehabilitation training, while the control group was by conventional acupuncture plus rehabilitation training. The Modified Ashworth Scale (MAS) and Modified Barthel Index (MBI) were evaluated before and after the intervention. The effects of the two methods in improving the upper-limb spastic intensity, hand function, and activities of daily living after cerebral stroke were evaluated based on the scores before and after the intervention. Result After treatment, the upper-limb spastic intensity and muscle tension decreased in both groups, and there was a significant difference in comparing the MAS score between the two groups (P<0.05); the improvement of MBI in the treatment group was more significant than that in the control group (P<0.05). Conclusion Acupuncture at Shixuan plus rehabilitation can produce a more significant efficacy in treating upper-limb spasm, improving hand function and activities of daily living after cerebral stroke, compared to the conventional acupuncture plus rehabilitation.

BACKGROUND:A large number of clinical trials have found that the number of bone marrow stem cels at the femoral neck and proximal femur in patients with osteonecrosis of the femoral head is significantly reduced, accompanied by decreased activity, which causes a significant decrease in osteogenic capacity that the necrotic bone cannot be effectively repaired after absorption, leading to the colapse of the femoral head. OBJECTIVE:To probe into the early clinical efficacy of autologous peripheral blood mononuclear cel transplantation with porous core decompression for treatment of avascular necrosis of the femoral head. METHODS:Forty-five patients with avascular necrosis of the femoral head (49 hips) were enroled in this study, and underwent autologous peripheral blood mononuclear cel transplantation with porous core decompression. After treatment, pain scores, Harris hip score, scores on the satisfaction of patients were evaluated, as wel as X-ray, CT and MRI examinations. RESULTS AND CONCLUSION:Al the patients received a folow-up visit of 11-14 months, averagely (12.5±0.6) months. During the folow-up, there were no complications and serious adverse reactions. Postoperative pain scores and Harris scores were both improved significantly compared with preoperative ones (P < 0.05). At 12 months after treatment, the excelent satisfaction rate was up to 92%. Patient’s MRI low signal region accounting for a percentage of the volume of the femoral head was decreased from (40.1±7.34)% preoperatively to (20.23±5.4)% at 6 months postoperatively, and there was a significant difference (P < 0.05). These findings indicate that autologous peripheral blood mononuclear cel transplantation with porous core decompression for treatment of avascular necrosis of the femoral head has significantly clinical effects at early stage, which can obviously reduce joint pain, improve and restore hip joint function, and delay progression of disease.
