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 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.

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.

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.

Objectives To analysis the main characteristics and changes of the internal death in pediatric intensive care unit (PICU) in the past five years. Methods The clinical data of 330 death cases in PICU internal medicine were retrospectively analyzed from January 2008 to December 2012. Results The mortality rate in PICU dropped from 5.85%to 3.96% from 2008 to 2012. Among 330 death cases, 136 cases (41.2%) were infants, 73 cases (22.1%) were toddlers, 51 cases (15.45%) were preschoolers, and 70 cases (21.21%) were school-age and adolescence. In different years, the differences of distribution of death in different age groups were statistical significance (χ2=6.90, P=0.009). In all years, the infant had the highest death rate. As the time progresses, the death rate of the infant and young children decreases, while the death rate of the school-age and adolescence increases. Among the diseases caused death, the cardiovascular disease was the most common disease (33.94%), followed by hematologic malignancy (31.52%). The difference of distribution of the diseases caused death in different age group was statistically significant (P<0.01). The cardiovascular disease was main cause of death in infant, and the hematologic malignancy was the main cause of death in other three age groups. Within 24 h admission, the pediatric critical illness score (PCIS) had been assessed, 67.49% was critical and 15.48%was extremely critical. The hospitalization time was negatively correlated with PCIS (r=-0.313, P<0.001). Conclusions In the past five years, the mortality in PICU declined year by year. Cardiovascular disease in infancy and hematologic malignancy in non infancy are the leading cause of death in children. Admission in critical or extremely critical condition is the reason of early death in hospital.

Objective The aim of this article is to research the radical mastoidectomy and primary tympanoplasty to attain radical cure of the mastoid focus as well as rebuilding the sound- conducting structure of the tympanic cavity to improve the audition. Method The autobone and temporal fascia were taken as the transplants after the radical mastoidectomy under microscopy, and then to carry out the operation of Portmann｀ s tempanoplasty of 2nd and 3rd types of 2nd class.Result Non of the cholesteatoma was relapsed after follow- up for 1～ 4 years.The efficiency rate of tympanoplasty is of 89.47% .The average audition increased was 19 dB HL. Conclussion Radical operation for cholesteatoma should be associated with tympanoplasty if having condition. We recommend that the opening tympanoplasty should be used, and use autobone as a artificial auditory ossicles.
