Objective To investigate the related factors of the retinal hemorrhage in high-risk infants (HRI).Methods Eight hundred and sixty HRI with histories of high-risk pregnancy and/or neonatal asphyxia after 1-5 days of birth were enrolled in this study.In 860 cases of HRI,498 infants were vaginal delivery and 362 infants were delivered through cesarean sections.Among 498 vaginal delivered infants,407infants were eutocia and 91 infants were with forceps delivery; 298 infants were born following normal labor,102 infants experienced prolonged labor,and 98 infants were urgent birth.The retinal hemorrhages were observed and conditions were graded into three degrees of Ⅰ,Ⅱ,and Ⅲ.Conditions of neonatal asphyxia were evaluated based on criteria of Apgar score.The incidence of retinal hemorrhage in the different types of deliveries and labor processes were compared,and the relationship between degree of retinal hemorrhage and grade of neonatal asphyxia were analyzed.Results In 860 cases of HRI,retinal hemorrhages were found in 202 infants (23.5％).Within these 202 infants,75 infants (37.1％) were Ⅰdegree retinal hemorrhage,75 infants (37.1％) were Ⅱ degree retinal hemorrhage,and 52 infants (25.8％)were Ⅲ degree retinal hemorrhage.In these 202 infants of retinal hemorrhage,172 infants (85.1 ％) had histories of asphyxia; 119 infants (69.2％) were graded as mild asphyxia-risk,and 53 infants (30.8％)were graded as severe asphyxia-risk.There was a statistical difference of the degree of the retinal hemorrhage between the mild and severe asphyxia-risk infants (x2 =34.61,P＜0.01).The incidence of retinal hemorrhage after vaginal delivery was higher than cesarean section delivery with significant statistical difference (x2 =30.73,P＜ 0.01).The incidence of retinal hemorrhage after forceps delivery was significantly higher than eutocia with statistical difference (x2 =62.78,P＜0.01).Both prolonged and urgent childbirth had statistically significant higher incidences of retinal hemorrhage compared to normal labor in the process of vaginal delivery (x2＝45.86,71.51; P＜0.01).Asphyxia,types of delivery,prolonged and urgent labors were risk factors of retinal hemorrhage for HRI (r=7.46,4.87,15.03,6.47;P＜ 0.01).Conclusions The incidence of retinal hemorrhage in high-risk infant was 23.5％.And,asphyxia,types of delivery,prolonged and urgent labors may play roles of risk factor in retinal hemorrhage of HRI.

Objective To explore the application of iPad-based software Let'S Talk in the rehabilitation of children with autism. Meth-ods From March to September, 2015, iPad-based software Let'S Talk was applied in four children with autism. The language ability, emo-tion and behavior control ability, self-consciousness and eye contact were observed. The Psycho-educational Profile-3rd (PEP-3), Autism Be-havior Checklist (ABC) and Childhood Autism Rating Scale (CARS) were used to access the months of age, behavior characteristics, and the severity of autism before and after application. Results The language ability and behavior control ability improved, as well as the self-consciousness and eye contact, and the bad behaviors reduced. The months of age rose in PEP-3, and the scores of ABC and CARS de-creased. Conclusion IPad-based software Let'S Talk could be applied in the rehabilitation of children with autism.

Objective To investigate the safety and feasibility of carotid artery stenting (CAS) and evaluate its clinical outcomes. Methods From July 1998 to December 2003, 30 consecutive patients with 32 lesions underwent extracranial CAS procedures. Thirteen patients had a history of stroke or TIAs, 22 were hypertensive, 11 were diabetic and 8 had history of MI. Neurological assessment, Carotid duplex ultrasound, carotid and intracranial angiography were done before CAS in all patients. All the cases were done percutanously from femoral arteries and stenting was applied in all procedures. Carotid duplex ultrasound, cardiac and neurological elevation were performed post procedure. Results 30 patients (26 male and 4 female) underwent a total of 32 CAS procedures. Total 32 self-expandable stents and 1 tubular stent were implanted in all the cases. Direct stenting technique was applied in 9 cases. The other 21 procedures were performed with distal filtration supporting devices. The device can not be delivered due to tortuous target vessel in one case (success rate 95%) and CAS success rate was 97%. The particles were found in all filter baskets. Four patients underwent coronary artery bypass grafting 1 month later post CAS without perioperative neurological and cardiac events. One patient had contralateral cerebral hemorrhage during CAS and died three days later. Another patient died three days after CAS due to acute pulmonary edema. No restenosis was found by means of carotid duplex ultrasound during the follow-up (3-60 months) study. Conclusion CAS is safe and feasible in preventing ischemic stroke. This new alternative has satisfied clinical outcomes in managing cardiac and neurological ischemic diseases. Operative embolic complication can be potentially prevented by neurological protective device.

Objective To explore whether the presence of juxtapapillary duodenal diverticula (JPDD) risks biliary stone disease and recurrence.Methods 829 patients undergoing ERCP in our hospital from Aug 2008 to Dec 2012 were divided into four groups:biliary stone disease (n =609) non-stone biliary abnormality (n =124) common bile duct malformation with cholelithiasis (n =38) and normal control group (n =58).There were 206 patients with JPDD and 623 patients without JPDD.Biliary stoneformation,post-ERCP pancreatitis,cannulation failure,and stone recurrence were compared between those with JPDD and those without.Results The incidence of JPDD in biliary stone disease group (27.8％) was significantly higher than in non-stone biliary anatomical abnormality group (18.5 ％) (x2 =4.512,P ＜ 0.05).In biliary stone disease group,rates of post-ERCP pancreatitis were significantly higher in JPDD cases (33.7％) compared to those without JPDD (13.8％) (x2 =30.841,P ＜ 0.05).The cannulation failure rate was also higher in patients with JPDD (15.4％) compared to JPDD negative (6.8％) (x2 =0.731,P ＜0.05).Recurrence rates in biliary stone disease were significantly higher in patients with JPDD (19.5％) when compared to JPDD-lacking individuals (9.3％) (x2 =14.51,P ＜ 0.05).Conclusions JPDD is a risk factor for biliary stone formation.JPDD also is associated with post-ERCP pancreatitis,cannulation failure and biliary stone recurrence.

Objective To investigate the effects of leptin on proliferation of the breast carcinoma MCF-7 cells in terms of protein and nRNA of Rab-25 and C-myc.Methods MCF-7 cells were treated with leptin and normal saline (NS) as control.The 490 nm OD values of cells were read by MTT and the protein and mRNA expressions of Rab-25 and C-myc were measured by western blot and RT-PCR methods in two groups.Results Compared with control group,leptin can promote the proliferation of MCF-7 cells in a dose and time dependent manner within certain limit and up-regulate the protein expressions of Rab-25 and C-myc in the breast carcinoma MCF-7 cells (P ＜ 0.05).However,leptin also can up-regulate the mRNA expressions of Rab-25 but without significance (P =0.05).On the contrary,leptin can also up-regulate the mRNA expressions of C-myc (P ＜ 0.05).Conclusion Leptin promotes breast cancer cells proliferation,which may be related to up-regulate the protein and mRNA expressions of Rab-25 and C-myc.It could provide theoretical foundation and new target of gene therapy in the clinical treatment of breast cancer.

Objectives To investigate the recurrence risk factors and the protective factors of aortic dissection (AD) DeBakey type Ⅲ. Methods 43 patients with AD DeBakey type Ⅲ who were in Guangdong General Hospital from May 2014 to September 2014, were enrolled as the case group, while 27 volunteers exclude AD as the control group. Blood chemistries and other information obtained immediately after admissions , χ2 test or T test was used for univariate analysis of independent samples. Multivariate Logistic regression analysis was used to screen patients with recurrence risk factors or protective factors. Results The prevalence of hypertension (93.02%vs. 18.52%, P = 0.000) and proportion of smokers (34.88% vs. 11.11%, P = 0.027) were significantly higher in case group than control group. Logistic regression analysis showed that hypertension (OR=5.148, 95%CI= [2.209~13.058], P=0.001) and albumin level (OR=0.709, 95%CI = [0.541~0.929], P=0.013) were significantly associated with recurrence of aortic dissection DeBakey type Ⅲ. Conclusion Hypertension is an independent risk factor for recurrence of aortic dissection DeBakey type Ⅲ, and albumin level is a protective factor.
