Objective To determine the pattern and incidence of congenital coronary anomalies (CCA) in adults undergoing coronary angiography. Methods The diagnostic angiographic data collected from October 2000 to October 2006 were reviewed, from which congenital coronary anomalies were found, and their angiographic features were studied. Results Among 1520 adults undergone coronary angiography, anomalous coronary arteries were found in 58 cases (3.82%). Depending on the anatomic characteristics of anomalous coronary arteries, these 58 cases were classified as following. Anomalies of origin and distribution were found in 26 cases (1.71%), among them separated origin of left anterior descending and left circumflex from left coronary sinus were found in 14 cases, left main trunk and left circumflex arising from right coronary sinus in 1 case for each, single left coronary artery in 2 cases, right coronary arteries arising from ascending aorta in 4 cases, from left coronary sinus in 3 cases, and from posterior coronary sinus in 1 case, respectively. Anomalies of coronary termination were observed in 11 cases (0.72%), and all of them were coronary artery fistulas. Anomalies of intrinsic coronary arterial anatomy in 21 cases (1.38%), among them myocardial bridge in 18 cases, hypoplasia of left circumflex artery in 2 cases, and sinus node artery arising from left posterior ventricular branch in 1 case. No anomalous collateral vessels were found. Conclusion Coronary angiography is one of the important methods of detecting anomalous coronary arteries. Classification based on the anatomic characteristics can help clarify the pattern and incidence of congenital anomalies of coronary arteries in adalts.

Objective To investigate the ability of decision-making under risk condition in benign epilepsy children with centrotemporal spikes (BECT).Method Seventy-eight BECT patients and seventyfive healthycontrols were studied by Iowa Gambling Task (IGT) with inexplicit probability and Game of Dice Test (GDT) with explicit probability.Results (1) There was a significant difference in IGT task scores between the two group (t=-2.56,P＜0.05).The total number of advantageous choices in IGT were lower in BECT group (49.35±5.38) than that in healthy control group (52.24±6.23).BECT group (-1.41 ± 10.60) performed worse on task than healthy control group (4.43±11.88),and the difference was statistically significant (t=-3.21,P＜0.05).The control group scored higher on Blockl,Block4 and Block5 than that of BECT group (P＜0.05).(2) There was no significant difference between the BECT group (4.42±7.74) and the control group(5.49±6.81) in the GDT test scores (t=-0.91,P=0.37).(3) Pearson correlation analysis showed that there was no significant correlation between the age,age of onset,education,seizure frequency and onset duration and the score of IGT and GDT (r =-0.091-0.274,all P ＞ 0.05).Conclusion There is no significant decision-making disability in children with BECT under the condition of certain risk probability,while there is significant impairment under the condition of uncertain risk probability.The decision-making disability may be associated with impaired frontal lobe function.

The Epstein-Barr virus (EBV) is a gamma herpes virus associated with several types of malignancies. The EBV encodes viral microRNAs (miRNAs) that can target genes within cells. The EBV participates in signal transduction as well as the proliferation and differentiation of cells. How the target genes and functions of EBV-encoded miRNAs contribute to the pathogenesis of EBV is an important research topic. Some target genes have been validated since EBV-encoded miRNAs were discovered and, in this article, we summarize them and their functions.
