RESUMEN
Objective To explore and analyze the clinical characteristics of extremely premature infants at low risk for early-onset sepsis (EOS) , so as to avoid overuse of antibiotics. Method The clinical data of extremely premature infants hospitalized from January 1, 2010 to December 31, 2017 were collected. Extremely premature infants born from mothers without premature rupture of membranes and without maternal clinical manifestations of chorioamnionitis during pregnancy were classified assigned into the low-risk group, and those who did not meet the low-risk conditions were regarded assigned intoas the control group. EOS was diagnosed according to the results of blood culture within 72 hours after birth. The clinical characteristics, treatment and outcome of extremely premature infants between the two groups were retrospectively analyzed. Results A total of 245 extremely preterm infants were enrolled, including 153 (62.4％) in low-risk group. Compared with the control group, mothers in low-risk group had higher rates of gestational diabetes and hypertension, higher rates of antenatal hormone use and lower rates of antenatal antibiotics use; furthermore, neonates in low-risk group had lower rates of Apgar score ＜ 5, higher rates of pulmonary surfactant use, respiratory support and mechanical ventilation, and lower risk of death and incidence of early-onset sepsis. The differences were statistically significant (P＜0.05) . Among In extremely premature infants whose having survival time＞ 24 hours, compared with control group, infants in low-risk group had higher incidences of respiratory distress syndrome, patent ductus arteriosus, intracranial hemorrhage and bronchopulmonary dysplasia, and lower incidence of pulmonary hemorrhage than control group, and the differences were statistically significant (all P＜0.05) . In low-risk group, the risks of death, respiratory distress syndrome, pulmonary hemorrhage and bronchopulmonary hemorrhage in long-term antibiotic group were higher than the short-term antibiotic group. Conclusion Early identification of extremely preterm infants at low risk of early-onset sepsis in extremely preterm infants is of clinical significance in reducing early empirical use of antibiotics therapy.

RESUMEN
MRI is one of the most important method in paediatric neuroimaging and can provide an ex-cellent anatomical overview with good spatial and temporal resolution. Meanwhile,it allows investigations of the blood vessels as well as three-dimensional structure. Diffusion-weighted imaging and magnetic resonance spec-troscopy are functional MRI,and they can differentiate many abnormalities,such as,ischemia,anoxia,inflamma-tion etc. Especially in patients with HIE,MRI helps assessing the severity of HIE and neurodevelopment progno-sis. This article reviews the brain MRI in predicting the neurodevelopment of infants and children with hypoxic-ischemic disease.

RESUMEN
OBJECTIVE:To study the effects of spirulina kinase(SPK)on the vascular endothelial function of model rats with atherosclerosis. METHODS:60 rats were randomly divided into normal control group(distilled water),model group(distilled wa-ter),positive control group(simvastatin,0.005 g/kg)and SPK low-dose,medium-dose,high-dose groups(80,160,320 U/kg). Except for normal control group,rats in other groups were induced for model of atherosclerosis. All groups were intragastrically ad-ministrated relevant medicines at the same time,once a day for consecutive 12 weeks. Total cholesterol(TC),triglyceride(TG), low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α) contents in serum of rats were measured. And the changes of thoracic aortic endothelium morphology were ob-served by HE staining. RESULTS:Compared with normal control group,TC,TG,LDL-C,IL-6,TNF-α contents in serum of rats in model group were increased(P<0.01),HDL-C content in serum was decreased(P<0.01);vascular endothelial cells fell off, intimal proliferation projected into the lumen,smooth muscle cell proliferated and disordered,medium film elastic fiber disintegrat-ed and fractured. Compared with model group,TC,TG,LDL-C,IL-6,TNF-α contents in serum of rats in administration groups were decreased(P<0.05 or P<0.01),HDL-C content in positive control group and SPK medium-dose,high-dose groups was in-creased (P<0.05). Vascular endothelial cell morphology was improved significantly in administration groups,in which,vascular endothelial cells were structurally intact in SPK medium-dose,high-dose groups,inner membrane was basically smooth;medium smooth muscle cells arranged slightly disordered in SPK medium-dose group. Compared with normal control group,there were no obvious changes. CONCLUSIONS:SPK shows obvious lipid-lowering and anti-inflammatory effects,it can protect vascular endo-thelial function. The mechanism may be related to reducing TC,TG,LDL-C,HDL-C,IL-6,TNF-αcontents and increasing HDL-C content in serum.
RESUMEN
Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is an autosomal recessive disease caused by SLC25A13 gene mutations, and is characterized by delayed jaundice clearance, liver dysfunction, and elevated aminoacidemia. The confirmed diagnosis depends on gene analysis. Citrin deficiency is one of the important causes of neonatal intrahepatic cholestasis in China. Recently more and more researches about NICCD were reported. The paper summarized the epidemiology, pathogenesis, clinical characteristics, and progresses in diagnosis and treatment of NICCD.
RESUMEN
Objective To explore the feasibility of using irreversible electroporation (IRE)mediating HPV16 E6 shRNA into cervical cancer cell line SiHa,and to clarify the influence of their co-effect on the proliferation of SiHa cells and its mechanism.Methods A HPV16 E6 gene specific interference sequence was inserted in pGenesil-1 to build a interference vector.10 pulses of IRE with 800 V,100 μs,and 1 Hz were applied to the suspension of SiHa cells and vectors.According to the treatment factors,control group,IRE group,pGenesil-N group,pGenesil-N+IRE group,pGenesil-E6 group and pGenesil-E6 + IRE group were set up.The expression of green fluorescent protein (GFP)and transfection efficiency were confirmed by inverted fluorescence microscope 24 h after the vector was transfected by IRE,and the expression efficancy of GFP was calculated.The expression levels of E6 mRNA and protein were detected by RT-PCR and Western blotting method which was also applied to detect the expressions of P53 and PCNA.The proliferative activity of SiHa cells was determined by CCK-8 assay.Results Enzyme digestion and DNA sequencing verified that the vectors were correctly constructed.GFP was seen under inverted fluorescence microscope 24 h after IRE transfection.Compared with IRE group,the expression levels of E6 mRNA and protein were decreased detected by RT-PCR and Western blotting method after the vectors were treated with IRE,the P53 protein expression level was increased (P < 0.05),and the PCNA expression level was decreased (P <0.05).The CCK-8 assay results showed the proliferative activity of SiHa cells in pGenesil-E6+IRE group was decreased more obviously than that in pGenesil E6 group (P <0.05).Conclusion IRE can play the role of gene transfection of mediating HPV16 E6 shRNA into SiHa cells, and their co-effect can significantly inhibit the proliferation of SiHa cells.
