OBJECTIVETo study the expression of histone acetyltransferases (HATs) and histone deacetylases (HDACs) in children with tetralogy of Fallot (TOF), and to investigate the role of histone acetylation and acetylation-related enzymes in the pathogenesis of TOF.
METHODSMyocardial tissue samples in the TOF group were obtained from 46 children with TOF who underwent radical operation, and myocardial tissue samples in the control group were obtained from 16 children who suffered accidental deaths and had no cardiac anomalies as shown by autopsy. The acetylation of H3K9, H3K18 and H3K27 was evaluated by immunohistochemistry. The mRNA expression of HATs and HDACs in the myocardium was measured by real-time PCR. The correlation between mRNA expression of HATs and HDACs and histone acetylation was analyzed.
RESULTSCompared with the control group, the TOF group showed significantly increased acetylation of H3K9 (P=0.0165) and significantly decreased acetylation of H3K18 (P=0.0048) and H3K27 (P=0.0084). As to 4 HATs and 6 HDACs, the mRNA expression of EP300 and CBP was significantly higher in the TOF group than in the control group (P=0.025; P=0.017), and there was no significant difference in the mRNA expression of other HATs and HDACs between the two groups. The correlation analysis revealed a positive correlation between H3K9 acetylation and mRNA expression of EP300 (r=0.71, P<0.01) and CBP (r=0.72, P<0.01).
CONCLUSIONSUpregulated mRNA expression of EP300 and CBP may be associated with increased H3K9 acetylation, suggesting that EP300 and CBP might affect cardiac development by regulating H3K9 acetylation.

OBJECTIVETo observe amplitude changes of low frequency fluctuation in brain spontaneous nervous activities induced by needling at Hand Taiyin Lung Channel, and to preliminarily explore the possible brain function network of Hand Taiyin Lung Channel.
METHODSBy using functional magnetic resonance imaging (fMRI), 16 healthy volunteers underwent resting-state scanning (R1) and scanning with retained acupuncture at Hand Taiyin Lung Channel (acupuncture, AP). Data of fMRI collected were statistically calculated using amplitude of low frequency fluctuations (ALFF).
RESULTSUnder R1 significantly enhanced ALFF occurred in right precuneus, left inferior parietal lobule, bilateral superior temporal gyrus, bilateral middle frontal gyrus, left superior frontal gyrus, left inferior frontal gyrus, left medial frontal gyrus. Under AP significantly enhanced ALFF occurred in right precuneus, bilateral superior frontal gyrus, cerebellum, bilateral middle frontal gyrus, right medial frontal gyrus, and so on. Compared with R1, needing at Hand Taiyin Lung Channel could significantly enhance ALFF in right gyrus subcallosum and right inferior frontal gyrus. Significant decreased ALFF appeared in right postcentral gyrus, left precuneus, left superior temporal gyrus, left middle temporal gyrus, and so on.
CONCLUSIONNeeding at Hand Taiyin Lung Channel could significantly change fixed activities of cerebral cortex, especially in right subcallosal gyrus, right inferior frontal gyrus, and so on.

Objective To evaluate the effect ofendovascular embolization on intracranial aneurysms with detachable coil and detachable balloon and to emphasize the mainpoint of embolization technique.Methods 1328 patients underwent complete cerebral angiography using microcatheter under DSA imaging. 85 cases with 90 aneurysms were embolized by MDS, 825 cases with 847 aneurysms were embolized by GDC, 418 cases with 433 aneurysms were embolized by EDC. 37 of 67 giant aneurysms were embolized by detachable balloon, 18 aneurysms by GDC, 11 aneurysms by EDC, 1 by MDS. Results 1328 patients with 1370 aneurysms were cured successfully; 1 322 cases recovered clinically, 6 patients died. 1 281 aneurysms achieved 100 % occlusion, 65with 95 % occlusion, 20 with 90 % occlusion, and 4with 80 % embolization. 9 aneurysms reputured during the embolization, 5 patients had cerebral infarction, 1 patient died of intractable cerebral vasospasm for microcoil escape. 2 recurrent cases were cured by second GDC embolization. Conclusion The method of endovascular embolization to treat intracranial aneurysm is safe, reliable and effective. Those cases with giant aneurysms will have high recurrence. Patients who suffer from SAH repeatedly may have great possibility of aneurysm rupture during embolization.

Lycopene liposomes were prepared by conventional rotary-evaporated film-ultrasonication method. The release of lycopene from lycopene liposome was evaluated in vitro. The pharmacokinetic parameters of lycopene liposomes (L-LYC) and lycopene (LYC) oil, the effect of LYC and L-LYC on antioxidation were also investigated in rats. HPLC method was used to assay the concentration of lycopene in rat's plasma. Pharmacokinetic parameters were estimated by 3P97 program. The release of L-LYC and LYC were measured in the artificial stomach liquid and bowel liquid. After 4 weeks of L-LYC or LYC feeding, the activity of SOD, T-AOC, GSH-Px, MDA and CAT in serum and liver were measured separately. The pharmacokinetic parameters of LYC oil and L-LYC in a single dose were 4.45 and 7.45 h for Tmax; 0.473 and 0.654 microg x mL(-1) for Cmax; 12.38 and 21.67 mirog x h x mL(-1) for AUC,respectively. The activities of GSH-Px and T-AOC in serum and liver of the L-LYC group increased (P < 0.05) and the concentrations of MDA and CAT decreased significantly (P < 0.05). It could be concluded that lycopene liposomes could prolong the time of absorption. L-LYC could increase antioxidative effect and reduce lipid peroxidation obviously compared with LYC in rats.

OBJECTIVETo study the relationship between pulmonary surfactant-associated protein B (SP-B) gene polymorphisms and their susceptibility to neonatal respiratory distress syndrome (RDS).
METHODSEighty-eight preterm infants with RDS (RDS group) and 103 infants without RDS (control group) were enrolled. The genomic DNA was isolated using DNA kits. Polymerase chain reaction with restriction fragment length polymorphism technique was used to detect the genotype and allele frequency of the SP-B -18A/C and SP-B 1580C/T single nucleotide polymorphisms. The association between the polymorphisms and RDS was analyzed.
RESULTSSP-B -18A/C and SP-B 1580C/T were found to be polymorphic in both RDS and control groups. The frequencies of CC genotype (X2=12.26, P<0.01) and C allele (X2=11.97, P<0.01) of SP-B 1580C/T were significantly higher in the RDS group than in the control group. The C allele significantly increased the risk of RDS (OR=2.26, 95%CI: 1.42-3.60). The frequencies of genotype and allele of SP-B -18A/C showed no significant difference between the two groups.
CONCLUSIONSSP-B 1580C/T polymorphism contributes to the etiology of RDS and may serve as the susceptibility gene for RDS. The C allele increases the risk of RDS. SP-B -18A/C shows no association with the etiology of RDS.
