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.

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.

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 prepare ambroxol hydrochloride orally disintegrating tablets and to evaluate its quality.METHODS:Mannitol was used as main adjuvant to prepare ambroxol hydrochloride orally disintegrating tablet,the UV spec-trometry was adopted to determine ambroxol content,the disintegration time,taste and dissolution rate were evaluated.RESULTS:The optimal formulation was composed of MCC 50g,mannitol 20g,L-HPC 10g,and NaHCO3 2g;The detected concentration of ambroxol was linear in the range of 0.005～0.030mg/ml(r=0.9 999),the average recovery was 100.50%and RSD=0.71;The prepared tablets disintegrated completely within 30s.CONCLUSION:The orally disintegrating tablets is quick to disintegrate and is as effective as market tablets.

Objective To explore the correlation between the change of intestinal flora and insulin resistance in pre-diabetes population,and the role of intestinal flora in the occurrence and development in the pre-diabetes population.Methods two hundreds and fifty cases of pre-diabetes in our hospital were selected and divided into the group A(pre-diabetes intervention group)and B(prediabetes non-treatment group).Fifty cases of diabetes(positive control group)served as the group C.The cohort study was adopted.The follow-up intervention lasted for two years.The intestinal flora and blood biochemical indicators were detected in different groups and at different time periods.The insulin resistance index was calculated.Results The total bacterial count before intervention in the group A and B was significantly higher than that in the group C;Enterococcus genus in the group C was significantly higher than that in the group A and B;the proteus and lactobacillus content in the group A and B was higher than that in the group C,but the difference was not significant;Bifidobacterium genus in the group C was higher than that in the group A and B.After intervention,the total bacterial amount in the group Awas significantly higher than the group B and C,but there was no statistical difference between the group B and C;enterococcus genus in the group C was significantly higher than that in the group A and B,enterococcus genus after intervention in the group A was reduced and which in the group B was increased,the difference had statistical significance;the proteus and lactobacillus content in the group A and B was higher than that in the group C,but the difference was not significant;bifidobacterium genus in the group C was higher than that in the group A and B,moreover which after intervention in the group B was increased,the difference was statistically significant.The insulin resistance before processing had no statistical difference between the groups A and B,which in the group C was higher than the group A and B,the insulin resistance after intervention in the group A was decreased,the difference was statistically significant.The total bacterial count,enterococcus and bifidobacterium were positively correlated with insulin resistance,and bacteroides,proteus and lactobacillus had no significant correlation with insulin resistance.Conclusion Intestinal flora has correlation with insulin resistance,and serves as a marker of pre-diabetes development,implementing the probiotics adjustment combined the quantization aerobic muscular movement can realize the adjustment of insulin sensitivity and improves the diabetic development in the prediabetic population.

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.
