ObjectiveTo explore the clinical effectiveness of intralesional glucocorticoid therapy on infantile hemangioma in proliferative stage,and variance of vascular endothelial growth factor(VEGF) expression in the hemangioma tissues.MethodsExperimental group:5 cases were injected with triamcinolone acetonide 3 days before operation,5 cases were done 6 days before operation,5 cases were done 9 days before operation and 5 cases were done 2 weeks before operation(the dose of injection was 1 mg/cm2 per time,but not exceeding 2 mg/kg).Control group:5 infantile hemangioma cases in involuting stage and 5 infantile hemangioma cases in proliferative stage did not received any therapy.The specimen of the hemangioma were collected to detect the expression of VEGF by two-step immunohistochemistry.Every optical slice was detected by 5 campus visualis of high power lens.ResultsObserving the specimen dyed by HE in the light microscope,there was no significant difference between injected group and non-injected group.But by means of immunohistochemistry,the expression of VEGF could been down regulation by the glucocorticoid(F=17.919 1P

Objective: To examine the regulatory effect of corticotrophin-releasing hormone (CRH) on glutamate-mediated current (IGLU) in cultured hippocampal neurons and to study the related mechanism. Methods: Immunofluorescence analysis was used to investigate whether the cultured hippocampal neurons express CRH receptors, and the whole-cell patch-clamp technique was used to examine the direct modulation of CRH on IGLU and the possible intracellular signal pathway. Results: Two minutes' exposure to CRH obviously depressed IGLU in the neurons in a dose-dependent manner. CRH receptor antagonist α-helical CRH or CRH receptor type 1 (CRHR1) antagonist antalarmin completely blocked CRH-induced depression of IGLU; whereas, CRH receptor type 2 (CRHR2) antagonist astressin-2B failed to block the effects of CRH. Application of the PKC inhibitor Gö6976 totally blocked the CRH-induced decrease of IGLU. Conclusion: CRH can inhibit IGLU in primary cultured hippocampal neurons, which is mediated by CRHR1 and may involve the PKC signal pathway.

Objective To analyze the clinical and molecular epidemiology in children with measles in Shanghai and identify the clinical characteristics and the prevalent genotype of measles virus.Methods The clinical features of measles-such as ages of onset,crowds and epidemiological data were retrospectively analyzed in 39 children with measles from Nov.2005 to Jun.2006 in Children′s Hospital Affiliated to Fudan University.Results of blood routine test,liver function test and chest X-ray were also included.Sputum examinations were carried out on the ones who had bronchitis or bronchopneumonia.Throat swab specimen within 3 days of the onset of rashes were collected and were sent to Center for Disease Control and Prevention (CDC) of Shanghai to isolate measles virus,then the genotypes of the isolated viruses were determined subsequently in CDC of China.Results Twenty-nine cases out of the 39 children were from foreign provinces (74.36%).Among of them,24 cases were younger than (or as young as) 9 months old.Among the 39 cases,35 children had never been inoculated with measles vaccine,and to speak of the ones who were younger than 8 months,the ratio was 57.14%.Five cases out of the 39 children had contacted with measles sufferers.Clinical manifestation were fever,rashes,Koplik spots and catarrh.Twenty-three cases were co-infected with respiratory system and only 8 cases were identified as infection with bacteria or other viruses.The genotype of all analyzed measles viruses belongs to H1a.Conclusions There are also some changes in age groups and endemic distribution,such as younger age and more immigrants except for the typical clinical manifestation of fever,rashes,Koplik spots and catarrh.The predominant genotype is still H1a as in most parts of China.There is no evidence to demonstrate any relationship between the raised morbidity of measles and the genovariation of measles virus.

Objective To explore diagnosis and prognosis of heart failure in children by measuring brain natriurettic peptide(BNP) and cardiac troponin I(CTnI).Methods Forty-one children subjects with heart failure were chosen,and then they were divided into three stages,early stage of heart failure,stage of heart failure and stage of recovery according to the ROSS cardiac function score method.In contrast with the former group,41 healthy children were chosen as control group.BNP and CTnI levels of blood plasma were analyzed by radioimmunoassay(RIA) and chemiluminescent immunoassay(CLIA) respectively,the relationship between the BNP level of blood plasma and prognosis of CHF group was analyzed.Results At early stage of heart failure,BNP and CTnI levels began to rise.They amount to highest peaks at stage of heart failure and went down at stage of recovery.But they were still higher than those of control group(P

Relevant literatures on the relationship betw een fluorosis and oxidative stress were reviewed.Based on most of the original papers published in recent years,we can see the increased free radicals and oxidative stress may occur in certain stage of fluoride intoxication,but confirmation of the causality between oxidative stress and fluoride-induced damages still remains much work to do.

Objective:To study the change rule of decocting quantity of the effective components in Amomi fructus and Amomi fructus rotundus with decocting time to determine whether or not decocted later and optimal decocting time. Methods:The herbs were extracted by the traditional water decoction, and at different time points, sampling was carried out. Using camphor and eucalyptol as the index components, the change rule of decocting quantity of the effective components with the decoction time under the condition of single and combined decoction was investigated. Results:When the decoction time of Amomi fructus was within the range of 3-6 min, the total amount of camphor in the decoction reached relatively high value, and the total amount lost more than 45% when the decoction time exceeded 10 min. Amomi fructus rotundus boiled for a short time below 2 min, and when the decoction time was more than 5 min, more than 50% eucalyptol lost. Conclusion:Amomi fructus and Amomi fructus rotundus should be decocted later with decocting time within 3-6min and below 2 min, respectively. The analytical method is reliable and precise in the quality control of relative decoction.

Neuronal damage is associated with the excessive stimulation of N-Methyl-D- Aspartate (NMDA) receptors by glutamate during cerebral ischemia.Because of non-selective NMDA receptor antagonist can influence all NMDA receptors and produce adverse effects,and its clinical application has been restricted significantly,an increasing attention has been paid to the selective NMDA receptor in recent years.NR2B subunit antagonists are mainly divided into piperidine derivatives,amide derivatives,amidine derivatives,and aminoquinoline derivatives,etc. The representative drugs include ifenprodil and eliprodil.These drugs can selectively act on NMDA receptor NR2B subunit,and they are expected to become safe and effective neuropro- tective agents in clinical practice.
