Objective To explore gene polymorphism of the C/T genotype of rs 16 944 in the promoter of IL-1β gene in male population living in the coastal area of Shandong,and thus to investigate the relationship between the gene polymorphism of IL-1β and gout.Methods A total of 276 gout patients and 268 healthy controls were enrolled.The possible association between the polymorphism of IL-1β-511 C/T and gout in Chinese was investigated and gcnotype frequencies and allelic frequencies were calculated by polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP) method.Hardy-Weinberg was used to verify the representativeness of the sample.Comparisons between the groups were performed with x2 test and t-test.Results There was no statistically difference in IL-1β-511 C/T genotype frequencies between gout patients and controls(x2=3.251,P=0.197,df=2).The allele frequencies of C and T in gout cases were not different from those in the controls (x2=2.941,P=0.086,OR=1.232,95％CI:0.971-1.563).Moreover,no association between IL-1β-511C/T genotypes and risk factors for gout were observed in gout cases by x2 test.Conclusion Results of the present study suggest that the C/T genotype of rs 16944 in the promoter of IL-1β gene is not associated with gout in male population living in the coastal area of Shandong.

The resident infection rate of schistosomiasis in Xinnong Village,Chuanxin Town,a national surveillance site of schistosomiasis.decreased to 0.14% in 2008.which suggested that the surveillance site reached the criteria for trammission control.

Objective To evaluate the imaging methods for cardiovascular malformations in Williams syndrome(WS).Methods Thirteen cases of WS(7 males and 6 females)aged 10 months to 13 years were involved in this study.All patients underwent chest X-ray radiography,electrocardiography.echocardiography and physical examination.3 cases underwent electronic beam computed tomography (EBCT),cardiac catheterization and angiography were performed in 8 cases.Results Twelve patients were referred to our hespital for cardiac murmur and 1 cnse for cyanosis after birth.7 patients were found with "elfin-like"facial features.6 patients with pulmonary arterial stenosis.2 Cases with patent ductus arteriosus.2 case8 with 8evere pulmonary hypertension and 1 case with total endocardial cushion defect.Sudden death occurred in 2 patients during and after catlleterization.respectively. Conclusions Conventional angiography is the golden standard for the diagnosis of cardiovascular malformations in WS.Noninvnsive methods such as MSCT and MRI should be suggested because of the risk of sudden death in conventional angiography.

Objective To evaluate the effect of self-expandable occluder on closure of patent ductus arteriosus(PDA)with severe pulmonary arterial hypertension(PH)in adults.Methods Twenty-eight adult patients underwent transcatheter closure of PDA at a mean age of(31.3?11.6)years [(18—58)years].Either Amplatzer duct occluder or domestic device was used in the present study.X-ray,EKG and UCG were repeated in one day,one month,three months,and six months.Results Twenty of the 28 patients had successful occlusion,and the other 8 patients were given up.In the successful group,the narrowest diameter of PDA was(10.4?2.7)mm [(6—16)mm],the diameter of selected occluder was(15.6?3.2)mm [(10—20)mm] at the end of pulmonary artery.Systemic artery oxygen saturation(SAsat)before and after oxygen inhalation was(93.5?1.8)%,(98.2?1.8)%,respectively(P

Objective To assess the safety and efficacy of balloon dilation of pulmonary valve stenosis with 10 F domestic balloon catheter in children ≥ 10 kg. Methods From May 2009 to June 2014, eighty-three consecutive children with weight ≥ 10 kg and age of (4.5±2.8)(ranged from 1-12) years underwent percutaneous balloon pulmonary valvoloplasty(PBPV) with 10 F domestic balloon catheter. Indication for treatment, procedural details, catheterization data, complication rate, peak-to-peak systolic gradient across the valve and pulmonary insufficiency on echocardiography were respectively analyzed. Forty-four patients were followed up 6-44 months after procedure. Results All procedures were completed successfully. The peak-to-peak systolic gradient across the pulmonary valve decreased from (67.7±26.2) mmHg to (15.4±11.6) mmHg (P < 0.01) immediately after PBPV. Two patients developed reactive infundibular spasm after dilation. They were relieved at 6 months post PBPV. No patient had severe pulmonary insufficiency, tricuspid regurgitation or reintervetion. Conclusions PBPV with 10 F domestic balloon catheter in children with weight≥10 kg is a safe and effective method.

Objective To define the diagnostic criteria of cardiovascular magnetic resonance imaging in distinguishing isolated left ventricular noncompaction (LVNC) from lesser degrees of hypertrabeculation. Methods Twenty-five patients with LVNC, 39 with dilated cardiomyopathy ( DCM), 16 with aortic stenosis(AS), 15 with aortic regurgitation(AR) , 19 with hypertension (HT) and 22 normal subjects were enrolled in this study. Cardiac magnetic resonance imaging was performed to evaluate the left chamber diameter, functional parameters and noncompaction or hypertrabeculation of the left ventricle in diastole with one-way ANOVA. The left ventricle was divided into 17 segments for localizing all involved segments in this present study. Results The LVNC patients had the commonest myocardial segments involved (10±2)in all subjects. Each patient with LVNC was unexceptionally associated with apical noncompaction (17th segment) , which was seldom found in the other subjects. The lateral walls including 16th, 12th and 11th segments were the most vulnerable segments in all subjects, but nobody was found to involve the basal and mid septum including 2nd, 3rd, 8th and 9th segments. The end-diastolic NC/C (noncompaction/compaction) ratio was, on average, the greatest in patients with LVNC (3.3±0.6), compared with all other subjects(AS:1.0 ±0.3, AR:1.0 ±0.3,HT:0.8 ±0.1,healthy volunteers:0.9 ±0. 2) (F = 169. 62,P <0.05). Receiver operating characteristics analysis identified the end-diastolic NC/C ratio of>2.5 as a valuable parameter to distinguish LVNC from DCM.with values for sensitivity of 96.O%(24/25)and specificity of 94.9%(37/39),respectively.The mean number of NC/C ratio>2.5 segments in the LVNC patients was 4.0 ±2.0.while 8 of 39 patients with DCM had only one segment of NC/C ratio >2.5.Conclusions MRI is all exceUent imaging modality to diagnose LVNC and distinguish LIVNC from hypertrabeeulation.The criteria of LVNC is the NC/C ratio>2.5 in two or more than two segments of free ventricular walls associated with the left ventrieular apex involved.

marked hi-atrial dilation, near-normal ventricular chambers and near-normal ventricular thickness were presented. Conclusion MRI is an excellent imaging modality for the diagnosis of restrictive cardiomyopathy.

According to the International League Against Epilepsy (ILAE) standards, the Newborn Working Group of the ILAE put forward 6 necessary questions about the management of neonatal anti-seizure medication and gave evidence-based recommendations in 2023. The basic framework is systematic review+expert consensus. The clinical recommendations of ILAE guidelines 2023 and the similarities and differences between ILAE guidelines 2023 and ILAE guidelines 2011 were analyzed and interpreted in this paper, in order to provide reference for colleagues involved in neonatal convulsion management in China.
