Because of the neonatal immune system is immature,particularly in preterm and low birth weight infants,the neonate is prone to some infections.Neonatal sepsis usually has the slight performance and atypical clinical symptoms,which raise the great interest of searching for some better biomarkers.With the development of testing technology,the research of serum inflammation marker has made remarkable progress at home and abroad in recent years,however,the research of umbilical blood inflammation marker is still in the early stage of exploration.Umbilical blood detection have the advantages of early,noninvasive,safe and convenient compare to the traditional serum detection.This paper mainly discusses the application of umbilical blood detection to early onset neonatal sepsis.

2,5-DKG reductase I was purified from cell-free extracts of a recombinant,ER97 by a procedure involving ammonium sulfate precipitation and successive column chromatography on DEAE-Sepharose CL-6B and Phenyl Sepharose CL-4B with 5 fold purification,27 % recovery and 3418 U/mg specific activity.The molecular weight of the enzyme estimated by SDS-PAGE was 34kD.The isoelectric point was estimated to be 6.0 by PAG-IEF.The optimum pH was 7.0 and the optimum temperature was about 40℃.The enzyme can catalyze the stereospecific NADPH-dependent reduction of 25-DKG to 2-KLG.The michaelis-menten constant(Km) for 2,5-DKG and NADPH were 0.29 mmol/L and 14.7 mmol/L respectively.The enzyme is specific for NADPH and 2,5-DKG,1 mmol/L Cu~(2+) or Zn~(2+) could highly inhibited the enzyme activity.EDTA and ?-Mercaptoethanol have no effect on the enzyme activity.

Objective: To analyze the constituents and metabolites of Radix Sa poshnikoviae (RS) in rat plasma and urine by rapid-resolution liquid chromatography-time of flight mass spectrometry (RRLC-TOF/MS), so as to explore the active ingredients and metabolites of RS in vivo. Methods: The separation was performed on a Angilent Zorbax Extend-C14 (5 μm, 250 mm x 4.6 mm id) column, with a methanol-water mobile phase system used for gradient elution. Time-of-flight mass spectrometer (TOF/MS) was applied for qualitative analysis under positive ion mode. Based on the accurate molecular weight of TOF/MS detection and the compound list of RS established previously, the constituents and metabolites of RS in different matrix in vivo were identified. Results: Six constituents of RS were identified in the plasma, sucrose, prim-O-glucosylcimifugin, cimifugin, nodakenetin, 5-O-methylvisamminol, and 3′-O-i-butyrylhammaudol. Eight constituents were identified in the urine, prim-O-glucosylcimifugin, divaricatacid, cimifugin, 4′-O-glucosyl-5-O- methylvisamminol, (3S)-2,2-dimethyl-3, 5-dihydroxy-8-hydroxymethyl-3, 4-dihydro-2H, 6H-benzo-[1, 2-b: 5, 4-b′] dipyran-6-one, 5-O-methylvisamminol, see-O-β-D-glucosylhammaudol, and wogonin. Two metabolites were identified in the urine, glucuronide of cimifujin and an isomer of it. Conclusion: The present method is reliable and effective for identifying compounds of RS in vivo, and it can provide a reference and evidence for the further pharmacodynamics experiments.

This article reviews the moral judgment ability of patients with autism spectrum disorder (ASD),as well as the relationship with theory of mind (TOM).The study found that patients with ASD could undertake basic moral judgment,but could not provide the corresponding judgment reason,and were easy to make utilitarianism judgment.In addition,individual's moral judgment ability was positively correlated with TOM,while there were defects in TOM among the patients with ASD,which could lead to the skew results of moral judgment.

Objective To investigate the differences of symptoms,physical signs and examinations in childhood and adult patients with Marfan syndrome.Methods Twenty-four children diagnosed as Marfan syndrome were investigated and evaluated synthetically in symptoms,physical signs and examinations.The positive rate of each item was analyzed to find the differences between childhood and adult patients.Results Among 24 patients,thorax and spinal deformity were found in 19 children(79%),leptosome type existed in 16 children(67%),dolichostenomelia was found in 15 children(63%).The dilation of the aortic sinus was detected in 16 children ((67%),)and the dilations of left ventricle and mitral regurgitation were found in 3 children(13%) with echocardiogram.Conclusions It is critical ascertain the abnormalities in cardiovascular system and give intervention,and it is expected to prolong the patients′ life by slowing down the changes in aortic walls.

Objective To study the cutoff point of chronic nasal sinusitis with nasal polyps(CRSwNP) classified by the tissue eosinophils(Eos).Methods 140 CRSwNP patients were enrolled in this study.The data of their clinical feature were collectted before surgery.Mucosal specimens were assessed for the presence of tissue eosinophil cells.Follow up and record the data at 3 months and 6 months after surgery.Results When the tissue Eos grouped by 50/HPF, the VAS, nasal sinus CT ,endoscopic preoperative score,and the endoscopic postoperative score at 3 months and 6 months showed significant difference(P<0.05).The tissue Eos between skin prick test(SPT) positive group and SPT negative group showed no significant difference.The tissues Eos was sighificantly correlated with the peripheral Eos(ρ=0.459,0.473,P<0.01).Conclusion The most meaningful cutoff point may be 50 Eos/HPF nearby to distinguish ECRS and non-ECRS(taken nasal polyps,by random HPF).Allergic factors may have no effect or little effect on the increase in Eos of nasal polyps in patients with CRSwNP;peripheral blood Eos may be an indicator of the level of Eos in tissues.

Infection can complicate different stages of acute pancreatitis.The probability of infection is related to the existence and extent ofpancreatic necrosis: up to 30% of patients with pancreatic necrosis develop infection.The timing of infection is variable and usually peaks in the second to fourth week after the onset of pancreatitis.IPN(infected pancreatic necrosis)is the most common type of secondary pancreatic infection.Infectious complications in severe acute pancreatitis are associated with considerable morbidity and mortality.Antimicrobial therapy is one of the fundamental elements of therapy.Diagnosis of secondary pancreatic infection is challenging and radiologic characteristic (air bubble sign) and CT guided fine-needle aspiration (FNA) are reliable diagnostic strategies.Antibioticuse should be rational in terms of a rational indication, a rational spectrum, and a rationalduration.Prophylactic antibiotics are not beneficial in improving prognosis.The only rational indication for antibiotics is documented infection.The empirical antibiotics should cover common microbials of hospital-acquired intra-abdominal infection and with good pancreatic penetration.Also, fungal infections are often present in thesepatients, and early diagnosis and antifungal coverage should be considered.Duration is in fact largely determined by the presence and efficacy of source control.When there is no or minimal residual infection left after a source control procedure, a duration of 7 to 10 days is probably sufficient.On the other hand, if the source of infection has not been removed completely, prolonged courses until the residual necrosis has been sterilized are necessary.
