Bedside ultrasonography is used to provide information about the cardiovascular system and the function and anatomy of certain internal organs,and help to guide the invasive procedures.Compared to traditional ultrasonography,bedside ultrasonography is more focused on the optimization of the treatment.It has become a necessary tool,as a powerful adjunct to the physical examination,in the management of critically ill patients in advanced countries.The development trend is the clinical protocol based on bedside ultrasonog-raphy.The application of bedside ultrasonography in China is limited,especially in PICU.Standardized educa-tion and quality assurance system are needed to its popularization.

Pediatric invasive fungal disease( IFD)often lacks characteristic clinical manifestations and imaging changes. It is a severe disease in ICU and is unlikely to be diagnosed early. The diagnosis of IFD is typically based on laboratory tests targeting at the population at risk. The laboratory tests for IFD generally include direct tests( smear microscopy,fungal culture,histopathologic examination,etc. ),serologic tests( tests for 1,3-β-D dextran and galactomannan,etc. ),and certain progresses have been made in molecular biologi-cal tests in recent years. It is key to diagnosis of IFD to use laboratory tests rationally and accurately interpret the laboratory results.

Objective To investigate the effect of pre pregnancy body mass index and maternal weight gain on pregnancy outcome. Methods The data of 3225 cases of single term birth primigravidae were collected from Guangzhou Maternity and Infant Hospital from June 1998 to June 1999. All of the cases were divided into three groups according to pre pregnancy body mass index (BMI): under weight group (BMI0.05). 2 Neonatal birth weight had a positive lineal correlation with the maternal weight gain in the three groups (calculated coefficient r were 0.596, 0.328 and 0.249, both of the P value were less than 0.01). 3 The incidence of pregnancy induced hypertension (PIH) increased significantly when maternal weight gained≥18 kg in the under weight and the ideal weight groups ( P

Staphylococcus aureus ( S. aureus) is one of the most common human pathogens. It has been reported that Panton-Valentine Leukocidin (PVL) as a representative of virulence proteins is an important pathogenic factor for S. aureus infection. However, with the deepening of research, some researchers consider that pvl gene has little effect on the pathogenicity of S. aureus. This article aimed to review and summarize the recent studies on the features, molecular epidemiological characteristics, pathogenicity and controversy of pvl gene.

Transcranial Doppler,a non-invasive ultrasonographic technique to detect the hemodynamic change of cerebral arteries,playing an important role in screening and diagnosis of cerebrovascular disease of adults,hasn′t been extensively applied in pediatric or universally understood by pediatrician.In this review,we will describe the application of Transcranial in the management of cerebral vasculopathy in children.

Based on the position and signifi cance of the syndrome in effect evaluation under the diagnose and treatment mode of the disease binding study and limitations of evaluation methods on some syndrome change,the article pointed out the comprehensive evaluation methods and possible ways by the combination of the evaluation on turnover regularity of syndrome and certain change of some syndrome,as well as preliminarily discussed several problems which should be paid attention to.

Pediatric advanced life support (PALS) training program development has been more than 20 years.PALS program provides a systematic,organized approach for the evaluation and management of acutely ill or injured children.It plays an active role in guiding treatment of critically ill children.In this paper,we reviewed the PALS training purpose,importance and training content,and introduced the current situation and promotion of PALS training in China.

Objective To investigate the psychological characteristics and personality of perinatal women, and to provide evidence for effective psychological intervention. Methods Five hundred and seventy pregnant women were randomly selected from the out-patient department from October, 2002 to March, 2003. Eysenck Personality Questionnaire(EPQ) , Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS) were applied for their personality, psychological characteristics and the influencing factors. Psychological surveys were performed in 216 cases in labor, and 300 cases were followed up during 1-5 days and 42-60 days postpartum. Results During pregnant period, the incidence of anxiety and depression was 10. 5% and 10. 2%, respectively, while 4. 0% and 5. 3% during early stage of puerperium. The rate of depression was 40. 7% and 10. 0% during late stage of puerperium and after puerperium. Pregnant women with personality of stability were less likely to have psychological disorder. Conclusions The rate of psychological disorder varies in different per sonallity. Proper intervention among high risk pregnant women is important in perinatal psychological

Objective Study changes and clinical significance of collagen and cytokine during COPD episode and remission in order to guide clinical treatment. Methods From Mar.2002 to Nov.2004,the COPD patients of episode and remission period were compared with the healthy elderly people.The collagen and cytokine of the serum from the COPD patients and healthy elderly people were detected by applying ABC-ELISA and radio-immunity means. Results The level of serum C_Ⅰ、C_Ⅲ、C_Ⅳ increased obviously in the COPD patients during COPD episode and remission episode compared with that in the healthy elderly people( P

Objective To evaluate the clinical effect of trans reformed catheter infusion for treatment of fallopian tube obstrution with Yuebei infertility.Methods 86 cases of fallopian tube obstrution were recanalized by trans reformed catheter infusion. Results 86 cases with 169 obstructive fallopian tube altogether, among them 119 were recanalized by once of this procedure, 33 by twice. The total effective rate was 89.9%. 86 cases were all followed up including 39 cases got pregnant after once of this procedure, 18 were pregnant after twice of the performance. The total pregnancy rate reached 66.3%. Conclusions Trans reformed catheter infusion therapy is a safe and effective method to treat infertility resulted from fallopian tube obstruction.
