Background Human paired box gene 6 (PAX6)encodes a transcriptional regulator.It is essential for eye and brain morphogenesis.Mutation of PAX6 gene isresponsible for many congenital ocular malformations,such as aniridia.Aniridia is a autosomal dominant inheritance mode.Objective In this study,PAX6 gene mutation was analyzed in three Chinese families with aniridia through polymerase chain reaction (PCR) and sequencing.Methods The blood specimens were collected from 5 suffers and normal individuals of 3 aniridia families to extract DNA.The sequences of extron 4-13 were designed based on PAX6 gene.The primer was amplified by PCR and sequenced and compared with the known PAX6 gene sequence.This study complied with Declaration of Helsinki and approved by ethic committee of Sichuan University.Written informed consent was obtained from each individual before any medial examination.ResultsThere were 5 suffers in the 3 families.A heterozygous mutation (c.718 C>T) in PAX6 gene was identified in 2 patients of family A.This mutation caused an amino acid substitution of arginine to termination codon at position 240 ( p.Arg240X) of PAX6 protein.No similar change in the normal families.No any the alteration of PAX6 gene was detected in family B whatever suffers and normal individuals.In family C,a deletion mutation of c.331 delG ( p.Val111 SerfsX13 ) in PAX6 gene was found.The deletion of one base caused frame shift mutation of PAX6 protein,and no such mutation was seen in other families.Conclusions Mutation of PAX6 gene appeares to be causative mutations of the disease in family A and C.

Objective To evaluate the clinical safety and efficacy of percutaneous interventional therapy in pediatric patients with secundum atrial septal defect(ASD).Methods Clinical data of 40 patients(age≤2 years)with secundum atrial septal defect treated in our hospital from February 2014 to December 2017 were analyzed retrospectively. There were 13 males and 27 females in these patients.Ultrasound of heart showed that there were 37 patients with single ASD,3 patients with multiple ASDs.One associated with pulmonary stenosis(PS),and 1 associated with patent ductus arteriosus.There were 6 patients with pulmonary hypertension, and the diameter of ASD was (10.6 ± 2.0) mm. All patients were proved to have secundum atrial septal defect before intervention.In the intervention,the transport system was delivered along the femoral vein,inferior vena cava and right atrium through atrial septal defect to the left atrium,and the occluder was released there. Results Of the 40 patients, 38 cases were successfully implanted, and the other two patients were not satisfied with the location of occlusion.The diameter of the ASD occluder was(12.0±2.1)mm and the transport sheath 7-9 F.Plug2 occluder was implanted in the patient with patent ductus arteriosus.To the patient with PS,pulmonary valve balloon angioplasty was performed,and then the pressure gradient reduced obviously, after that ASD occlusion was performed. The total follow up period was from 2 months to 3 years.No residual shunt and unsatisfactory device position were found during the follow up period.The pulmonary pressure reduced to normal,and the right atrium and right ventricle were smaller in a different degree. All patients had no arrhythmia and other complications.Conclusion Transcatheter closure of ASD is safe,reliable,and has fewer complications.It is worthy of popularization and application.Appropriate occluder should be selected according to the size and edge of ASD to reduce complications,such as residual shunt and valve injury.

OBJECTIVETo investigate the hereditary tendency of varicocele.
METHODSWe included in this study 112 varicocele patients, 117 direct male relatives of the patients, and 100 healthy men as controls. We compared the incidence of varicocele tween the direct relative group and the control group.
RESULTSThe direct male relatives of the varicocele patients had a significantly higher incidence of varicocele than the healthy controls (36.8% vs 17%, P < 0.05).
CONCLUSIONThe increased incidence of varicocele in the direct male relatives of the patients indicated a hereditary tendency of the disease.

OBJECTIVETo investigate the life style, genetic and occupational risk factors of metabolic syndrome (MS) among policemen.
METHODS1:4 matched case-control study was used, based on physical examination data of Tianjin Policemen in 2010, 708 patients with MS were randomly selected as cases, which were matched with 2832 healthy controls on the basis of sex and age (+/- 1 year). An epidemiological investigations on the past exposure status of several possible risk factors was conducted, and the data were analyzed with conditional logistic regression.
RESULTSFifteen factors related to exposure were identified for MS through univariate conditional logistic regression analysis. Multivariate conditional logistic regression analysis suggested that, seven factors, such as family history of hypertension (OR = 2.406, 95% CI: 1.946-2.975), family history of diabetes (OR = 1.301, 95% CI: 1.043-1.623), smoking (OR = 1.357, 95%CI: 1.010-1.823), snoring (OR = 1.268, 95% CI: 1.043-1.543), work intensity (OR = 4.603, 95% CI: 3.767-5.623), occupational stressful events (OR = 1.524, 95% CI: 1.209-1.922), security policemen (OR = 1.453, 95% CI: 1.127-1.872) and criminal investigation policemen (OR = 2.792, 95% CI: 2.168-3.596), could significantly increase the risk of disease development, but dairy products (OR = 0.782, 95% CI: 0.619-0.989) was a protect factor for MS. The results from population attributable risk factors analysis showed that the control of smoking, snoring, work intensity, occupational stressful events can decreased the risk of MS to 16.26%, 11.71%, 56.87% and 8.97%, respectively.
CONCLUSIONMetabolic syndrome has became a significant public health problem among policemen, it's necessary to take measures on life style, occupational risk factors for reducing the incidence of MS, and improving the health level among policemen.

BACKGROUNDInterleukin-23 (IL-23) is a pro-inflammatory cytokine that is thought to be central to the development of autoimmune diseases. This study was conducted to determine whether or not the serum concentration of IL-23 is elevated in patients with rheumatoid arthritis (RA), and to determine the relationship between the IL-23 level and disease activity in RA patients.
METHODSSerum samples were obtained from 59 patients with RA and 30 healthy controls. The clinical parameters of disease activity were determined, including the 28-joint disease activity score (DAS28), C-reactive protein (CRP), rheumatoid factor (RF) levels, and the degree of bony erosions based on X-rays. The levels of IL-23 and IL-17 were determined by enzyme-linked immunosorbent assay (ELISA). The correlations between the serum levels of IL-23 and disease activity parameters of patients with RA were determined.
RESULTSThe serum IL-23 level was significantly elevated in patients with RA compared to healthy controls. The serum IL-23 levels in the RA patients correlated with IL-17 and CRP levels, and the DAS28. The levels of IL-23 based on X-ray classification phase I, II, III, and IV were gradually elevated in RA patients.
CONCLUSIONSThe levels of serum IL-23 in RA patients were higher than in healthy controls. Thus, elevated serum IL-23 levels may be useful markers to detect active RA. In addition, IL-23 is involved in disease progression and bony erosions in patients with RA.
