Objective To study the proportion of cyclic vomiting syndrome(CVS) developing to migraine by the medium term prognosis,and explore the relationship between CVS and migraine.Methods Twenty-eight of 38 cases who had identified in our clinical records were traced ,each child was matched to a control,and they all conducted a telephone interview by a standardized question.Results Ninteen(46%) of the subject had continued CVS and(or) migraine,the prevalence of past or present migraine in subjects(46%)was significantly higher than that in control group(10.7%)(P=0.003).Conclusion The progonosis of CVS is closely related to migraine,many of the suffers of CVS tend to develop migraine.

Objective To explore the diagnostic value of neuron-specific enolase(NSE) in cerebrospinal fluid(CSF) in children with meningitis.Methods NSE levels in CSF of 18 children with purulent meningitis,13 children with tuberculous meningitis and 25 children with viral meningitis were determined by enzyme-linked immunosorbent assay(ELISA).Results CSF-NSE levels increased significantly in children with purulent meningitis and tuberculous meningitis compared with that of control group(P0.05);CSF-NSE levels increased significantly in children with purulent meningitis and tuberculous meningitis,compared with that of viral meningitis group(P0.05).Conclusions The determination of the neuron-specific enolase in cerebrospinal fluid can be used as an important parameter for identifying bacterial meningitis from viral meningitis.It also can be used to estimate the severity and prognosis of meningitis in children.

Congenital heart disease with left-to-right shunt easily lead to pulmonary hypertension.Currently agreed about its mechanism:shear stress induced by high pulmonary blood flow stimulus pulmonary endothelium,to start regulation of genetic transcription,to initiate a series of molecular biology and pathophysiology changes,and finally to lead to pulmonary vascular pathologic remolding.Nuclear factor(NF)-?B is a kind of nuclear factor with multiple biological effect and play an important role in pulmonary vascular remolding.NF-?B signal can be actiacted by high blood flow.Its target gene products,for example,vasoactive mediators,cytokines,make pulmonary vessels difficulty to maintain the normal structure and cause pulmonary vascular contraction and remolding,thus,pulmonary arterial pressure increases.
