Globally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.All the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.A total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents concern about the long-term outcomes was the main reason of medical care withdrawal.Neonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.

Objectives To explore the feasibility of using enhanced-flow (e-flow) imaging technology to identify fetal pulmonary veins and establish gestational age-specific reference values at 12-40 weeks' gestation. Methods The pulmonary venous internal diameter, peak systolic and diastolic flow velocities and visualization rate were analyzed in 332 normal fetuses at 12-40 weeks of gestation. Two-dimensional gray-scale (2D) ultrasound, color Doppler and e-flow imaging were used to detect the pulmonary veins in the four-chamber view by taking the lung as the penetration window. Results The pulmonary veins could be visualized as early as 12 weeks' gestational age by e-flow imaging. The right and left pulmonary venous internal diameters and peak systolic and diastolic flow velocities increased with increasing gestational age. Between 12 and 40 gestational weeks, the internal diameter and both the systolic and diastolic flow velocities of the fetal right pulmonary vein were significantly larger than were those of the left vein (P < 0.05). Of 118 fetuses at 12-22 gestational weeks, the visualization rate of the four pulmonary veins (left superior and inferior, right superior and inferior) was 5.9% (7/118) by 2D ultrasound, 41.5% (49/118) by color Doppler and 61.9% (73/118) by e-flow imaging. The visualization rate by e-flow imaging was significantly higher than that using the other two techniques (P < 0.001). Conclusion e-flow imaging is apparently a feasible and promising technology with which to identify the fetal pulmonary veins in the early stages of the second trimester. Copyright © 2011 ISUOG.

MicroRNAs are important regulators of multiple cellular processes, and aberrant miRNA expression has been observed in human glioblastoma (GBM). The present study was to evaluate the level of miR-124 and signal transducer and activator of transcription 3 (STAT3) in GBM tissues and cells. We further investigated the molecular mechanisms of miR-124 and STAT3 in GBM cell lines U87 and U251. Here, we found that miR-124 expression was downregulated in GBM tissues and U87 and U251 cells (all p<0.001) but not associated with blood routine (RBC, WBC count, etc.) and liver and renal function indicators (all p>0.05). By contrast, STAT3 was upregulated. Furthermore, the expression of miR-124 was inversely proportional to that of STAT3 mRNA or protein (p=0.013, p=0.015, respectively). In vitro studies demonstrated that the overexpression of miR-124 played a suppressor role in the proliferation of U87 and U251 cells and promoted cell apoptosis. Luciferase reporter assays confirmed that miR-124 binding to the 3-UTR regions of STAT3 inhibited the expression of STAT3 in U87 and U251 cells. However, the inhibitor of miR-124 promoted the expression of STAT3 and cell proliferation. In conclusion, our data suggest that miR-124 may have a potential role in treatment of GBM patients and that miR-124 is a novel regulator of invasiveness and tumorigenicity in GBM cells by targeting STAT3. The miR-124/STAT3 pathway may be a useful therapeutic agent in GBM patients.

Biomimetic collagen/hydroxyapatite scaffolds have been prepared by microwave assisted co-titration of phosphorous acid-containing collagen solution and calcium hydroxide-containing solution. The resultant scaffolds have been characterised with respect to their mechanical properties, composition and microstructures. It was observed that the in situ precipitation process could combine collagen fibril formation and hydroxyapatite (HAp) formation in one process step. Collagen fibrils guided hydroxyapatite precipitation to form bone-mimic collagen/hydroxyapatite composite containing both intrafibrillar and interfibrillar hydroxyapatites. The mineral phase was determined as low crystalline calcium-deficient hydroxyapatite with calcium to phosphorus ratio (Ca/P) of 1.4. The obtained 1% (collagen/HAp = 75/25) scaffold has a porosity of 72% and a mean pore size of 69.4 μm. The incorporation of hydroxyapatite into collagen matrix improved the mechanical modulus of the scaffold significantly. This could be attributed to hydroxyapatite crystallites in collagen fibrils which restricted the deformation of the collagen fibril network, and the load transfer of the collagen to the higher modulus mineral component of the composite. © 2014 Jilin University.

The concept of health-related quality of life (HRQoL) was brought up decades ago and has been well utilized in many different areas. Regarding immune thrombocytopenia (ITP) management, much work has been done to emphasize the necessity of taking HRQoL into consideration. However, data on HRQoL of children with chronic ITP remain rare.This is a cross-sectional study. Children with chronic ITP aged from 2 to 18 and their parents were recruited. Participants completed the Pediatric Quality of Life Inventory (PedsQL) and Kids ITP Tools (KIT) questionnaires at only one time. The Pearsons correlation was examined between these measures for the pooled samples.A total of 42 families participated. Mean child self-report scores of KIT and PedsQL were 78.60 (SD = 12.40) and 85.13 (SD = 14.12), respectively, corresponding to parent proxy report scores, which were 73.40 (SD = 19.96) and 85.10 (SD = 13.56), respectively. Mean score of KIT parent impact report was only 40.39 (SD = 19.96). Significantly higher KIT scores (self-report and parent proxy) were observed in children with PLT more than 30 10*9/L compared to others, and this difference was even more noticeable in the PedsQL parent proxy report group (p < 0.001). As with intravenous immunoglobulin, the statistics difference appeared only in KIT child self-report group (p = 0.03), while for bone marrow examination, the difference appeared only in PedsQL parent proxy report group (p = 0.01). A negative relationship was apparent between duration of disease and scores. Gender and use of corticosteroids had no impact on the KIT and PedsQL scores here. Internal consistency reliability was demonstrated with Cronbachs alpha for all scales above the acceptable level of 0.89 (range from 0.88 to 0.97). There was a substantial concordance (p < 0.001) between the child and parent proxy scores (ICC for KIT is 0.59, ICC for PedsQL is 0.85). Meanwhile, KIT scores are correlated with PedsQL (r = 0.75 for child self report, r = 0.61 for parent proxy report).ITP affects HRQoL of children and parents. Parents are much more concerned with the disease than their children, which seriously influence their HRQoL as a result. The cross-culture translated KIT is reliable and valid with acceptable correlation to the PedsQL. KIT provides valuable information of childhood ITP and will be a reliable outcome measure for further clinical research on HRQoL.

OBJECTIVE: To evaluate the efficacy of targeted tidal volume ventilation in the treatment of severe neonatal respiratory distress syndrome (RDS). Methods: Eighty-four neonates with severe RDS between June 2008 and January 2010 were randomly assigned to 3 groups according to the ventilation mode: synchronized intermittent positive pressure ventilation plus volume guarantee (SIPPV+VG; n=31), high frequency oscillation ventilation (HFOV; n=23) and intermittent mandatory ventilation (IMV; n=30). The oxygenation status, the durations of oxygen exposure and ventilation and the incidence of complications were observed. Results: The oxygenation status (P/F and a/APO2) in the SIPPV+VG and the HFOV groups was improved significantly 12 hrs after ventilation (P<0.05). While in the IMV group, the oxygenation status was not improved until 24 hrs after ventilation. The durations of oxygen exposure and ventilation in the SIPPV+VG and the HFOV groups were shorter than in the IMV group (P<0.05). The incidences of air leak syndrome and ventilation-associated pneumonia (VAP) were lower in the SIPPV+VG and the HFOV groups than in the IMV group (P<0.05). The incidence of severe intracranial hemorrhage in the HFOV group was higher than in the other two groups (P<0.05). Conclusions: Compared with IMV, SIPPV+VG and HFOV can improve the oxygenation status more quickly, shorten the ventilation duration and decrease the incidences of air leak syndrome and VAP in neonates with severe RDS.

To investigate the effect of continuous veno-venous hemofiltration (CVVH) on inflammatory mediators in children with severe hand, foot and mouth disease (HFMD), and to investigate its clinical efficacy.A total of 36 children with stage IV HFMD were enrolled and randomly divided into conventional treatment group and CVVH group (n=18 each). The children in the CVVH group were given CVVH for 48 hours in addition to the conventional treatment. The levels of interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor- (TNF-) and lactic acid in peripheral venous blood, heart rate, blood pressure, and left ventricular ejection fraction were measured before treatment and after 24 and 48 hours of treatment.After 24 hours of treatment, the conventional treatment group had a significantly reduced serum IL-2 level (P<0.01), and the CVVH treatment group had significantly reduced serum levels of IL-2, IL-6, IL-10, and TNF- (P<0.05). After 48 hours of treatment, both groups had significantly reduced serum levels of IL-2, IL-6, IL-10, and TNF- (P<0.01), and the CVVH group had significantly lower levels of these inflammatory factors than the conventional treatment group (P<0.01). After 48 hours of treatment, heart rate, systolic pressure, and blood lactic acid level were significantly reduced, and left ventricular ejection fraction was significantly increased in both groups, and the CVVH group had significantly greater changes in these indices except systolic pressure than the conventional treatment group (P<0.01).CVVH can effectively eliminate inflammatory factors, reduce heart rate and venous blood lactic acid, and improve heart function in children with severe HFMD.

Renal cell carcinoma (RCC) is the most common type of kidney cancers in adults, and metastasis represents the major cause of mortality of RCC patients. The Y-box binding protein 1 (YB1) is a multifunctional oncoprotein in various malignancies. Enhancer of zeste homolog 2 (EZH2), a polycomb histone methyltransferase, is a key epigenetic modifier implicated in various cancer metastasis. However, the expression patterns and clinical correlations of both YB1 and EZH2 in RCC remain largely unclear. In this study, the expression of YB1 and EZH2 were examined using immunohistochemistry staining in a study cohort including 165 RCC and 80 tumor adjacent normal tissues. RCC tissues showed a significant higher nuclear expression of YB1 (p < 0.001) and EZH2 (p < 0.001) as compared with the normal counterparts. In addition, YB1 and EZH2 nuclear overexpression were found to be positively associated with RCC stage (p < 0.001 and p = 0.005), Fuhrman tumor grade (p = 0.022 and p = 0.044), and metastasis (p < 0.001 and p = 0.009). Overall survival analysis indicated patients with YB1 (p = 0.004, HR 5.656 (2.006–10.944)) and/or EZH2 (p = 0.006, HR 4.551 (2.124–9.438)) nuclear overexpression correlated with poor survival. More interestingly, YB1 and EZH2 nuclear expression was correlated (p = 0.005). Further studies demonstrated that EZH2 expression was significantly downregulated in YB1 knockdown RCC cell lines. Functionally, YB1 knockdown inhibited RCC invasion in vitro. In conclusion, YB1 and EZH2 expression was correlated and associated with RCC incidence, tumor stage, grade, metastasis, and survival. © 2015, International Society of Oncology and BioMarkers (ISOBM).
