1.How to nutritional support for pediatric liver failure
Chinese Pediatric Emergency Medicine 2017;24(1):13-16
Malnutrition occurs as a result of inadequate nutrient intake,malabsorption and altered me-tabolism in pediatric liver failure. Malnutrition may be associated with a poor outcome. The current evidence indicates that the provision of adjunctive nutritional support ( parenteral nutrition or enteral nutrition or nutri-tional supplements) to patients with a variety of liver diseases. It may be reasonable to start enteral nutrition in 5 to 7 days in acute liver failure or hepatic coma. According to individualized appropriate nutritional evalu-ation,the metabolic demand,to provide appropriate nutritional support in pediatric liver failure.
2.The extracorporeal membrane oxygenation related complications and prevention
Chinese Pediatric Emergency Medicine 2017;24(2):144-148
The complications of extracorporeal membrane oxygenation ( ECMO ) include technical relevance complications and physical relevance complications. The former mainly includes dysfunction of oxygenation,cannula-related problems,technical relevance hemolysis,blood clots of oxygenator or rest of the circuit. The latter includes hemorrhage and embolism,culture-confirmed infection,renal failure and neurologic complications. One of the most reported complications of ECMO is hemorrhage. It′s important for reducing mortality and improving prognosis through stricting with the indications of ECMO,strengthening team cooper-ation,closely clinical monitoring and early identifying complications. In this paper,we introduced complica-tions of ECMO as well as how to prevent and treat it.
3.Relationship of Janus Kinase-Signal Transducers and Activator of Transcription Signal Transduction and Neurogenesis in Neonatal Rats with Periventricular Leukomalacia
Journal of Applied Clinical Pediatrics 2006;0(20):-
Objective To observe the relationship of the Janus kinase-signal transducers and activator of transcription pathway and neurogenesis in the lateral ventricle subventricular zone(SVZ) and choroid plexus of neonatal rats with periventricular leukomalacia(PVL).Methods PVL models were established by right common carotid artery ligation followed by 4 h 60 mL/L oxygen exposure in 2-day-rat;the neonatal rats performed a sham operation,without hypoxia-ischemia were used as control group.The rats were sacrificed at 0 h,3 h,6 h,12 h,1 d,3 d and 7 d after hypoxic-ischemic(HI),and brain tissues were collected,immunohistochemistry was used to detect the expression of P-STAT3 and Nestin in the subventricular zone and choroid plexus.Results Very low expressions of P-STAT3 and Nestin were observed in lateral ventricle SVZ and choroid plexus in control group.The expression levels of P-STAT3 and Nestin increased significantly after HI,peaked at 1 d and 3 d separately,and remained at a higher level at 7 d after HI,demonstrating significant differences at each time point compared with those in control group(Pa

Objective To study the effect of amelogenin (AML)on the migration,adhesion and proliferation of periodontal ligament stem cells (PDLSCs).Methods STRO-1 +PDLSCs were selected by Flow cytometer.The transwell system was used to detect the effect of AML on migration of PDLSCs.Cells attachment assay was used to detect the effect of AML on adhesion of PDLSCs.MTT was used to detect the effect of AML on the proliferation of PDLSCs.Results The results of transwell showed that AML could induce the migration of PDLSCs with positive correlation.Cells attachment assay showed that the adhesion of PDLSCs was effected by AML as well,and the effect was in-creased with the extension of incubation time.Results of MTT showed that AML could promote the proliferation of PDLSCs in a dose depend-ent manner.Conclusion AML could increase the proliferation,adhesion and migration potential of PDLSCs.

Objective To investigate the accuracy of three dimensional facial measurement system based on structured light projection, and explore the methods to reduce noise of the output images. Methods The known object for calibration was measured by the measurement system to correct the parameters of the system and enhance the measurement accuracy. The mechanism of noise was analysed, and the noise and sundry of the images were eliminated. Results The parameters of each assembly of system were obtained by calculation and calibrated, and the measurement accuracy (0.028 mm) of three dimensional facial measurement system based on structured light projection was increased. Application of image processing technology reduced the noise and sundry of output images. Conclusion The accuracy of three dimensional facial measurement system based on structured light projection is high. The image output is reliable, and can be clinically used in facial scanning and three dimensional reconstruction.

Objective To measure plasma microRNAs dysregulated in patients with pancreatic cancer and to assess the potential of these miRNAs as biomarkers for pancreatic cancer.Methods Thirty-seven patients with pancreatic cancer who underwent pancreatic resection between June 2010 to July 2011 were enrolled in the Lihuili Hospital,and ten healthy volunteers were used as control in this study.The expression levels of miR-190,miR-196a,miR-221 and miR-222 were analyzed using quantitative real time polymerase chain reaction (qRT-PCR).U6 was used as an internal control.The relationships between clinicopathoiogic characteristics of pancreatic cancer and microRNA expression levels were analyzed.Results The relative abundances of plasma microRNAs were significantly higher in pancreatic cancer patients than in the control group.The highly expressed plasma miR-190,miR-196a,miR-221,miR-222 levels did not correlate with clinicopathologic characteristics of patients such as sex,age,tumor maximal diameter,and level of serum CA199.The plasma miR-196a levels showed a positive correlation with TNM stage in pancreatic cancer patients.Conclusions The plasma levels ofmiR-190,miR-196a,miR-221 and miR-222 were highly upregulated in pancreatic cancer patients.These microRNAs in plasma may provide a new method in the early diagnosis of pancreatic cancer.

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P
