Objective To investigate the status and demands of prenatal education among pregnant women,and to provide reference for better prenatal education. Methods A total of 750 pregnant women were recruited from 20 hospitals in Chengdu and were investigated with a serf-designed questionnaire. Results 74.42% of the pregnant women had participated the prenatal education,25.58% of them didn't take even one prenatal class. The most preferred knowledge was newborn care. They most preferred to take prenatal classes at weekends in small group. The women's educational level,family income, delivery experience and times of prenatal check-up were the key factors to affect the participation in the prenatal educa-tion. Conclusions It is suggested to innovate the contents and means of prenatal education in order to attract the pregnant women to participate prenatal education actively.

Objective To investigate the changes of plasma activated protein C(APC)in the pediatric leukemia patients with acute lung injury(ALI),and the relationship with the outcome.Methods During the study period(from Jan to Dec 2009),17 pediatric leukemia patients with ALI were selected.They were divided into neutropenic(n =10)and non-neutropenic(n =7)group.We collected the basic data including the age,gender,stage of chemotherapy,pediatric critical illness score,mechanical ventilation time,ICU time.The blood gas and plasma APC levels were detected on day 1 and day 4 of ALI onset.Results Compared with the non-neutropenic group,the neutropenic group had a significantly longer mechanical ventilation time [(16.60 ± 1 0.83)d vs(3.79 ± 4.08)d,P =0.009 6],lower PaO2 level on day l[(54.90 ± 17.05)mm Hg vs (92.70 ± 27.53)mm Hg,P =0.009 7],and lower APC level on day 4[(193.06 ± 63.19)pg/mlvs(286.28 ±25.12)pg/ml,P =0.007 7].Conclusion The APC generation is severely impaired in the neutropenic group,especially in those who died.The lower APC level is,the longer is the mechanical ventilation time,the worse is oxygenation,the poorer is the prognosis.APC replacement therapy may be promising in these patients.

Objective To investigate the clinical manifestations of the febrile neutropenia cancer children,explore the relationship between the clinical data and sepsis.Methods A prospective observation study was employed,and 66 cancer children complicated with febrile and neutropenia after chemotherapy were enrolled.Sixty-six cases were divided into two groups:septic group ( n =26 ) and non-septic group ( n =40).Clinical and laboratory data were collected and compared.Results Body temperature,neutropenia duration,absolute neutrophic count ( ANC ),C-reactive protein ( CRP ),procalcitonin (PCT) and culture positive rate showed statistically differences between the septic and non-septic groups ( P ＜ 0.05 ).Body temperature ＞40 ℃,ANC ＜ 0.1 × 109/L,increases of serum CRP and PCT levels and positive culture were correlated with sepsis.Body temperature ＜ 39 ℃,neutropenia duration ＜ 5 ds,ANC ＞ 0.5 × 109/L were less correlated with sepsis.Conclusion High initial temperature,long duration of neutropenia,severely reduced ANC,increases of CRP and PCT,and culture-positive are correlated with sepsis in cancer children.

Objective To investigate the pathogen of 21 infective endocarditis (IE) cases treated with operation in Shanghai Children's Medical Center from 2007 to 2010.Methods Blood culture,vegetation culture and vegetation PCR assay(target gene to the conserved region V3 in 16SrRNA gene) were detected in 21 IE patients; multiplex PCR amplification of staphylococci for methicillin-resistant staphylococcus was performed.Results Of 21 IE cases,20 cases were detected positive by vegetation PCR with the detection rate of 95.2％,12 IE cases were detected positive by blood culture with the detection rate of 57.1％,2 IE cases were detected positive by vegetation culture with the detection rate of 9.5％.The difference of the positive rates of the three methods was statistically significant (P ＜ 0.0001).The vegetation PCR of one case was actinobacillus actinomycetemcomitans,while the blood culture was haemolysis pasteurell which was inconsistent with the vegetation PCR result.Howerver,the PCR result of colony obtained by blood culture was consistent with vegetation PCR that was confirmed as actinobacillus actinomycetemcomitans.The endocardium PCR results of 11 IE cases were consistent with the results of blood culture.MecA gene was detected by multiplex PCR,which could identify methicillin-resistant staphylococcus quickly,sensitively and accurately and could also effectively identify methicillin resistant staphylococcus aureus,when coupled with femA gene detection,thus glycopeptides antibiotic could be prescribed promptly.All the 21 patients recovered and discharged without infection recurrence in the follow-up.Conclusion Universal primer V3 coupled with multiplex PCR can improve vegetation pathogen detection rate of IE patients and is minimally influenced by antibiotic therapy.Multiplex PCR can be applied for etiological diagnosis of IE patients with indication of surgery and negative blood culture or difficult diagnosis,contributing to post-surgery antibiotics selection and improvement of recovery rate of IE patients.

ObjectiveTo assess the relationship between serum macrophage migration inhibitory factor (MIF) and sepsis in children with hematologic malignancy.Methods( 1 ) An observational study was performed in a university pediatric intensive care unit.Forty-one children were enrolled in our study,and were divided into two groups:sepsis group (27 cases) and non sepsis group ( 14 cases).(2) Serum samples were taken in the both two groups in 24 h after they were admitted in hospital.Clinical and laboratory parameters,including the levels of serum MIF,cortisol,corticotropin releasing hormone ( CRH),and ferritin were measured and compared between the two groups.Multiple linear regression analysis was used to assess the relationship between MIF and CRH,cortisol and pediatric critical illness score (PCIS).ResultsThe level of MIF was significantly elevated in the sepsis group[ (5 022.71 ± 3 915.82) pg/ml] than that of non sepsis group[ ( 1 722.81 ± 1 738.53) pg/ml] (P =0.001 ).Multiple linear regression analysis showed that CRH as well as PCIS were the correlative factors of MIF( t =- 2.830,P =0.009; t =2.852,P =0.009 ).The higher CRH concentration,the lower PCIS score,and the higher MIF was.ConclusionThe level of serum MIF could reflect the severity of children with hematologic malignancy complicated with sepsis.The higher MIF concentration,the lower PCIS score,then the disease is more serious.To some extent,serum MIF is related with the adrenocortical function of sepsis children.

Objective To explore the safety and therapeutic efficiency of continuous renal replacement therapy(CRRT) without anticoagulation for critically ill children with high risk of bleeding.Methods We retrospectively analyzed 51 patients undergoing bedside CRRT in the PICU of our hospital from December 2007 to July 2015.Patients were divided into two groups induding CRRT with anticoagulation(n=33) or without anticoagulation (n=18).The therapeutic efficiency and complications were compared between two grous.Results Totally 168 CRRT circuits were performed in these 51 patients including 62 (36.9％)circuits without anticoagulation in 18 patients with high risk of bleeding and 106(63.1％) with anticoagulation by heparin.The circuits life of CRRT without anticoagulation was (12.31±6.64) h,which was shorter than that of CRRT with anticoagulation [(17.43±9.97)h] (P＜0.001).The levels of blood creatinine,blood urea nitrogen,C-reactive protein,and lactate significantly improved after both therapies (P＜0.05).PT and APTT did not change in CRRT without anticoagulation for hemorrhagic complications(P＞0.05).APTT[(52.36±5.00)s vs.(76.48±9.02)s,P=0.013] and PLT[(127.3±20.85)×109/L vs.(95.52±15.46)×109/L,P=0.041]were significantly longer in CRRT with anticoagulation by heparin compared with those before treatment.Conclusion CRRT without anticoagulation reduces bleeding risks and achieves an acceptable circuit life.The strategy can be applied as an alternative to critically ill children at high risks of bleeding who need continuous blood purification.

Objective To explore the relationships among post traumatic stress disorder(PTSD),gratitude and posttraumatic growth (PTG) for terminal cancer patients.Methods Totally 119 advanced cancer patients were investigated with the self-demographic questionnaire,posttraumatic growth inventory (PTGI),the PTSD cheeklist-civilian version (PCL-C) and the Gratitude Questionnaire-6 (GQ-6).Results For terminal cancer patients,the total score of PCL-C was 34.02±12.49.The scores on re-experience,avoidance/numbness,hypervigilance were 9.79±3.78,13.85±5.68,10.36±3.80.The total score of gratitude was 29.37±7.48.The total score of PTG was 51.34± 13.57.The scores of life appreciation,personal relationship and self-strength were 8.00± 2.99,21.18± 5.84,22.16± 6.10.The total scores of PTG were significantly statistical significance among different PTSD groups(F=16.267,P＜0.01)and gratitude groups(F=43.674,P＜0.0 1).The total scores of PCL-C (r=-0.694,P＜0.01),re-experience (r=-0.664,P＜0.01),avoidance/numbness (r=-0.671,P＜0.01),hypervigilance (r=0.753,P＜0.01) and gratitude(r=-0.611,P＜0.01) were all correlated with PTG.The total score of PCL-C and gratitude could explain 66.6％ variation of PTG.For the relationship between PTSD and PTG,the moderation effect of gratitude was not significant (P ＞0.05).Conclusion The gratitude and PTSD were important influence factors for terminal cancer patients' PTG,while the moderation effect of gratitude was not significant,so in clinical intervention we should pay more attentions to the actual effects of gratitude,and we should not pursuit gratitude education blindly.
