Objective To explore the clinical value of real-time three-dimensional echocardiography (RT-3DE) in percutaneous transcatheter closure treatment of atrial septal defect (ASD). Methods The sizes,shapes and sites of ASD were visualized by RT-3DE and measured by full volume rendered three-dimensional echocardiography (3DE) before operation and after closure operation in 11 ASD patients,and compared with those from two-dimensional echocardiography(2DE) and the operation. Results Before the operation,RT-3DE visualization showed that the secundum ASD′s sites of the 11 patients were central and shapes were mostly ellipse. In this study a significant difference was found in the measurements of long distances of ASD between 3DE and 2DE [( 28.9 ? 8.2 )mm vs ( 20.0 ? 7.3 )mm,P 0.05 ]. Maximal diameters of defects measured by 2DE[( 21.1 ? 3.5 )mm,P

Polyethersulfone hollow fiber membranes were prepared from polyethersulfone/N, N-Dimethylacctamide/poly (N-vinyl-2-pyrrolidinone) systems by dry/wet phase inversion process using water as coagulation bath. The effects of coagulation bath temperature and air gap distance on the surface structure, cross section structure and water flux of membranes were discussed. As increasing the temperature of coagulation bath and the air gap distance, the size of the pores at the surface effectively increased, while the finger-like structure under the outer surface changed to a sponge-like structure.

OBJECTIVETo study the effect of different delivery modes on immunoprophylaxis efficacy so as to clarify whether or not cesarean section reduces immunoprophylaxis failure.
METHODSMothers with positive hepatitis B surface antigen (HBsAg) were selected in the third trimester of pregnancy. Their babies were inoculated with hepatitis B immunoglobulin at birth and hepatitis B vaccine at 1, 2 and 7 months of age. HBsAg and its antibodies (anti-HBs) were tested at 1, 4, 7, and 12 months of age, then followed up yearly.
RESULTSA total of 301 babies entered the study, including 144 born by normal spontaneous vaginal delivery, 40 by obstetric forceps or vacuum extraction, and 117 by cesarean section. The incidence of mother's HBeAg positivity or baby's gender constitution was comparable between the three groups. There were no significant differences in the positive rate of anti-HBs or HBsAg at follow-up periods among the three groups. At 12 months of age, anti-HBs could be detected in 78.9% of the babies born by normal vaginal delivery, 84.6% of the babies by forceps or vacuum extraction, and 86.4% of the babies by cesarean section. The positive rate of HBsAg was 8.1%, 7.7%, 9.7%, and chronic HBV infection incidence was 7.3%, 7.7%, 6.8% respectively.
CONCLUSIONSThere are no significant effects of delivery mode on the interruption of HBV maternal-baby transmission by immunoprophylaxis. Cesarean section does not reduce the incidence of immunoprophylaxis failure.

Objective Toinvestigatetheeffectofrehabilitationrobothandontheupperlimbmotor functioninpatientswithstrokeandhemiplegia.Methods Theeffectsoftraditionalrehabilitation therapy or robot rehabilitation treatment of 15 stroke patients with hemiplegia were analyzed retrospectively. There were 4 females and 11 males. According to the group order,they were divided into either a robot rehabilitation group (n=8 )or a general rehabilitation group (n =7 ). The patients of the general rehabilitation group received general rehabilitation training at the Department of Rehabilitation Medicine for 4 weeks,3 times a week,and 30 min for each time. At the same time,they also conducted family rehabilitation training,5 times a week,once for 1 h;the patients of the robot rehabilitation group received the general rehabilitation training for the same length of time as the general rehabilitation group,and they also performed robot rehabilitation training,5 times a week,once for 1 h. The patients of both groups were evaluated with the modified Ashworth scale (MAS )scores,Fugl-Meyer motor assessment of the upper extremity(FMA-UE),andWolfmotorfunctiontest(WMFT)beforeandaftertreatment.Results Compared with before training,the MAS score of the robot rehabilitation group was decreased significantly after four weeks of training. The time in WMFT was shortened significantly and the function score was improved obviously. The scores of upper extremity,hand score,and total FMA score in FMA-UE were improved significantly,and there were significant differences (all P <0. 05 ),while there were no significant differences in various indicators in the general rehabilitation group (all P>0. 05). Comparing the effects after four weeks of rehabilitation in both groups,the robot rehabilitation group was superior to the general rehabilitationgroupforthehandscoreinFMA-UE(allP<0.05).Conclusion Therehabilitation robot hand effectively lowered the upper limb spasticity. It has significant effect for recovery motor function of hand;however,it did not have a significant effect for motor rehabilitation on wrist.
