Objective To investigate the mental health state of twin pregnancy women and influencing factors,so as to provide reference for measures to improve their mental condition.Methods Sixty twin pregnancy women who have made regular antenatal examination received the investigation of Self-Rating Anxiety Scale (SAS),Self-Rating Depression Scale (SDS) and self-designed questionnaire.Results The score of SAS for twin pregnancy women was (52.87±10.19) points,SDS was (50.61±4.31) points.There were significant differences in twin pregnancy women degree of anxiety with different age,gestational weeks,and pregnancy way and degree of depression with different gestational weeks,pregnancy way and abortion,reproductive history (F/t=12.74-54.93,P ＜ 0.05 or 0.01).Regression analysis showed that gestational weeks and pregnancy way were the main factors of anxiety and depression influencing twin pregnancy women.Conclusions The anxiety state of twin pregnancy women is in a moderate level,and the depression is mild.It is influenced by the factors of gestational weeks and pregnancy way.Some aspects should be improved:such as strengthen psychological care,establish standardized management model,twin pregnancy women are encouraged to self-control,the use of high qualification by social and family support system,and so on.

Objective To evaluate the effect of IKAP(Information-Knowledge-Attitude-Practice) theory on twin pregnancy women′s psychological states, satisfaction and childbirth outcomes. Methods One hundred twin pregnancy women who had made registrations and antenatal examination were divided into the intervention group and the control group with 50 women in each group according to randorn digit table. The twin pregnancy women in the control group received routine antenatal examinations. In addition, the twin pregnancy women in the intervention group received a special health education with IKAP theory. The twin pregnancy women′s anxiety, depression, birth outcomes and satisfaction were measured and compared between the two groups. Results The score of Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) in the intervention group was 27.64±2.86 and 26.53±2.96 one week after delivery, significantly lower than those upon admission, 44.18 ±2.53 and 47.42 ±4.82, the difference was statistically significant (t=5.41, 4.49, P<0.01), also lower than those of the control group, 46.53±2.39 and 39.68±3.78, the difference was statistically significant (t=3.63, 6.82, P<0.01). No significant difference was seen in SAS and SDS scores between upon admission and one week after intervention in the control group (P>0.05). In the intervention group the rate of cesarean section was 29.17% (14/48), and the score of satisfaction was (9.01±0.78), they were also significantly higher than those of the control group, 53.06%(26/49), (7.82±1.44), the difference was significant (χ2=7.701, t=4.806, P<0.05). There were no significant differences in the delivery pregnancy week, volume of bleeding 2 hours postpartum and Apgar score between the two groups (P>0.05). Conclusions The IKAP theory on twin pregnancy women can decrease the anxiety, depression and the rate of cesarean section, and increase patient satisfaction.

Objective To evaluate if replication-defective herpes simplex virus mediated kynurenine aminotransferase Ⅱ (HSV-KAT Ⅱ) could inhibit detrusor overactivity (DO) in rats with spinal cord injury by bladder wall injection.Methods From June 2012 to July 2013,48 male Wistar rats with T10 spinal cord transection (SCT) were randomly divided into normal saline group,HSV group and HSV-KAT Ⅱ group (n=16 each group).Normal saline (40 μl),HSV or HSV-KAT Ⅱ (40 μl,1×107 plaque forming unit viruses) was injected into the rat bladder wall of according group by 1 week after SCT.Three weeks after injection,cystometry was performed and the virus transfected efficiency,expression of KAT Ⅱ in L6-S1 dorsal root ganglia were examined.Results The DO number,DO amplitude,maximum voiding pressure and volume inducing voiding were decreased significantly by 59.6％-61.1％,21.6％-24.2％,30.3％-34.4％ and 44.1％-46.5％ (P＜0.01),while voiding efficiency,the time to first DO were increased significantly by 40.7％-47.7％ and 30.1％-49.0％ (P＜0.01) in the HSV-KAT Ⅱ group compared with normal saline group and HSV group.However,the leaking volumes were no significantly different among the 3 groups (P＞0.05).The relative intensity of KAT Ⅱ protein (0.50±0.13 versus 0.28±0.07,P＜0.05) and mRNA (0.78±0.06 versus 0.51±0.08,P＜0.01) were increased significantly in HSV-KAT Ⅱ group than those in HSV group.Conclusion HSV-KATⅡ bladder wall injection inhibits DO and may improve detrusor-sphincter dyssynergia in rats with spinal cord injury.
