ObjectiveTo study the effect of three-level monitoring mode in reducing complications of pediatric PICC catheter tube and improving the quality of care for children. Methods64 cases of children with PICC catheter in our hospital from September 2009 to August 2011 receiving three-level monitoring modes were set as the experimental group.67 patients with conventional care from September 2007 to August 2009 were set as the control group.The incidence of catheter complications in children,success rate of catheter puncture and tube indwelling time for the two groups were observed. Results The complications occurred in 9 cases,accounting for 14.06％ in the experimental group.The complications occurred in 25 cases in the control group,accounting for 37.31％.The puncture success rate was 89.06％ in the experimental group,and the control group was 79.10％.The average time of tube indwelling in the experimental group was higher than the control group.The difference was significant. ConclusionsThe effect of three-level monitoring modes to reduce pediatric PICC catheter complications and improve quality of care in children with catheter is significant,it can increase the success rate of puncture and prolong tube in-dwelling time.

Objective To explore the relationship between parenting stress and social support, cop-ing style in mothers of children with autism. Methods 105 mothers with autistic children(the observation group) and 100 mothers with healthy children (the control group) were investigated by questionnaires, which included parenting stress index-short form (PSI-SF), social support scale and simplified coping style questionnaire. And then the relationship between parenting stress, social support and coping style was ana-lyzed among them. Results Mothers of children with autism experienced a significantly higher level in the total score of parenting stress and all the domains when compared with mothers of healthy children. Par-enting stress was negatively correlated with social support. Conclusions Mothers of children with autism generally experience a significantly higher level than parents of healthy children in the total parenting stress and all the domains. Social support could reduce parenting stress of mothers with autistic children.

Objective To analyze the clinical factors for pathologic complete response ( pCR) after preoperative neoadjuvant chemoradiotherapy ( neo?CRT) for locally advanced rectal cancer. Methods From 2005 to 2012, 297 patients with locally advanced rectal cancer and complete clinical data were enrolled as subjects. Those patients were diagnosed with biopsy and treated with neo?CRT ( radiotherapy by 3?dimonsional conformal radiotherapy or volumetric?modulated arc therapy) followed by radical surgery. The logistic regression model was used for the multivariate analyses of the correlation of pCR with age, gender, distance between tumor and the anal verge, serum level of carcinoembryonic antigen ( CEA ) before treatment, hemoglobin level before treatment, cT staging, and cN staging. Results In all patients, 78 ( 26?7%) patients had pCR after treatment. The numbers of patients with pCR were 42( 34?4%) in patients with stage T1?T3 disease and 37(21?1%) in patients with stage T4 disease. In the patients with serum CEA levels no higher than 5?33 ng/ml, 55(36?4%) had pCR after treatment, while in the patients with serum CEA levels higher than 5?33 ng/ml, only 24( 16?4%) had pCR. The univariate analysis revealed that age, gender, distance between tumor and the anal verge, anemia before treatment, or cN staging were not related to pCR. The multivariate analysis showed that stage cT1?T3 and a serum CEA level no higher than 5?33 ng/ml before treatment were influencing factors for pCR after neo?CRT for locally advanced rectal cancer ( P=0?031,P=0?000) . Conclusions The clinical staging and the serum CEA level before treatment are influencing factors for pCR after neo?CRT for locally advanced rectal cancer. The serum CEA level before treatment can be considered as a predictor of pCR after neo?CRT for locally advanced rectal cancer.
