Objective: To investigate the interaction between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and sleeping duration on risk of stroke in a Chinese Han ethnic population. Methods: In the case-control study and epidemiological investigation, the self-reported sleep duration and MTHFR C677T polymorphism of 245 patients with cerebral infarction, 222 patients with cerebral hemorrhage and 282 controls were collected. Multiple logistic regression was performed to analyze the interaction between MTHFR C677T polymorphism and sleeping duration on risk of stroke. Results: After adjustment for major confounding variables, multiple logistic regression analysis showed that: (1) There was significant association between long sleep duration (>8 hours of sleep per night) and cerebral infarction (OR=3.90; 95% CI:2.43-6.26), but not for cerebral hemorrhage (OR=1.16, 95% CI: 0.71-1.92). On the other hand, insomnia (sleep duration less than 6 hours) was neither associated with cerebral infarction nor hemorrhage. (2) MTHFR TT genotype increased the risk of cerebral infarction significantly (OR=2.01; 95% CI:1.12-3.61), but not for cerebral hemorrhage (OR=1.16,95% CI:0.71-1.92). (3) There was a significant synergistic effect of interaction between MTHFR TT677 genotype and long sleep duration on risk of cerebral infarction (OR=6.22; 95% CI:2.44-15.83). Conclusion: MTHFR TT677 genotype and long sleep duration increase the risk of cerebral infarction independent of confounding factors, respectively. Furthermore, there is a significant synergistic effect between MTHFR TT677 genotype and long sleep duration on risk of cerebral infarction in the Chinese Han ethnic population.

Objective To investigate the CT findings of cardiac rhabdomyoma in childhood. Methods Five children with cardiac rhabdomyoma confirmed by operation was retrospectively analysed. Enhanced electron beam CT (EBCT) was performed in 4 children and enhanced 64-slice helical CT (MSCT) scan was performed in 1 infant. Three dimensional reconstruction was applied for the full display of the lesions based on the transverse section images. Results ( 1 ) Multiple masses or nodules originated from atrioventricular septum were observed in 4 children including 1 nodule from the anterior walls of the left and right ventricles. A mass was derived from the mitral valve in 1 infant (2) The CT value of the lesions after enhancement ranged from 80 to 180 HU and was similar to neighbouring left ventricular myocardium. (3) The ventricular outlet obstruction was found in 3 children including 1 infant with pericardial effusion and pulmonary inflamation of the right lower lobe. Conclusion The rhabdomyoma should be considered first when masses or nodules originated from atrioventricular septum and with the enhancement similar to neigbouring left ventricular myocardium in children.
