1.Influence of Intralesional Glucocorticoid on the Expression of Vascular Endothelial Growth Factor in Heman-gioma Tissues
Journal of Applied Clinical Pediatrics 2006;0(23):-
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
2. Regulatory effect of corticotrophin-releasing hormone on glutamate-mediated current in cultured hippocampal neurons
Academic Journal of Second Military Medical University 2010;30(3):233-237
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.
3.Value of Brain Natriurectic Peptide and Cardiac Troponin I in Diagnosis and Prognosis on Heart Failure in Children
Journal of Applied Clinical Pediatrics 2006;0(24):-
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
4.Clinical and Molecular Epidemiological Characteristics in Children with Measles
Journal of Applied Clinical Pediatrics 2003;0(10):-
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 the relationship between severity of symptom and immune function in left-to-right shunt congenital heart disease (CHD) infants combined with pneumonia. Methods The clinical data of 45 left-to-right shunt CHD combined with pneumonia infants were retrospectively analyzed. The infants were divided into 2 groups according to the modified Ross score:mild group (0-6 scores, 28 cases) and severe group (7-12 scores, 17 cases);then, the infants were divided into 2 groups according to deformities:single deformity group (the infants had a kind of deformity such as ventricular septal defect, atrial septal defect and patent ductus arteriosus, 21 cases) and composite/complex deformity group (the infants combined 2 or more deformities or other malformations, 24 cases). Twelve cases of healthy check-up infants were selected as control group. The levels of lymphocyte subsets (including CD3+, CD4+, CD8+, CD4+/CD8+, NK cell and B lymphocyte) and IgG, IgA, IgM were detected in every group. Results There were no statistical differences in IgG, IgA, IgM, CD8 +, CD4 +/CD8 +, NK cell and B lymphocyte among mild group, severe group and control group or single deformity group, composite/ complex deformity group and control groups (P>0.05). The CD3+ in severe group was significantly lower than that in mild group and control group (0.59 ± 0.10 vs. 0.69 ± 0.13 and 0.69 ± 0.12), the CD4+was significantly lower than that in control group (0.34 ± 0.07 vs. 0.45 ± 0.09), and there were statistical differences (P<0.05). For CD4+, though there was statistically difference among single deformity group, composite/complex deformity group and control groups (P<0.05), no statistically significant difference was in multiple comparison among the 3 groups (P>0.05). The CD4 + in the composite/ complex deformity group was significantly lower than that in the single deformity group and the control group (0.34 ± 0.07 vs. 0.45 ± 0.15 and 0.45 ± 0.09), and there was statistical difference (P<0.05). Conclusions In left-to-right shunt CHD infants combined with pneumonia, the reduction of CD3+and CD4+may be one of the causes of serious illness.

Objective To study the levels of umbilical plasma ?-endorphin (?-EP) in normal and abnormal pregnancy and the influencing factors. Methods The umbilical plasma ?-EP concentrations of 95 cases were measured by radioimmunoassay. Linear regression was used to find out the influencing factors of ?-EP including: neonatal gestational age, gender, birth weight, mode of delivery, maternal hypertension, maternal diabetes, premature rupture of membranes(PROM) and fetal distress. The subjects were divided into two groups: healthy term newborns and preterm neonates. Results Gestational age, mode of delivery and fetal distress were important factors influencing umbilical blood ?-EP production (P
