Mild cognitive impairment(MCI)is a new concept put forward in recent years.It is a transtrional state between normal aging and dementia.Prospective studies have shown that the orbebility of the patients with MCI converted to dementia is significantly higher than the normal aged.population.The correct diagnosis of MCI contributes to screen the high-risk population of dementia.It will provide the possibility for preventing dementia and decreasing the morbidity of dementia.

Objective To investigate the clinical and pathological features of children malignant lymphoma.Method A retrospective study was carried out to analyse the clinical,laboratory and pathological data in 65 patients with malignant lymphoma.Results In the chidren malignant lymphoma,the incidence of nonHodgkin′s lymphoma(NHL) was more than that of Hodgkin′s disease(HL),the ratio of NHL to HL was 2.25∶1.The peak incidence of age was among 6 to 9 years old,the ratio of male to female is about(3.5∶1.)NHL of our children was mostly consised of lymphoblastic lymphoma,anaplastic large-cell lymphoma,diffuse large B-cell lymphoma and Burkitt′s lymphoma.The clinical manifestations were predominantly presented with peripheral nodes intumescing,mediastinal tumeur,abdominal tumeur,bone marrow infiltration.In patients with Hodgkin′s disease,mixed cellularity was the most common pathological category,and cervical painless lymphadenectasis was usually the initial signs in most patients,sometimes accompanied with infiltration of celiac lymph nodes,spleen and bone marrow.Conclusions NHL of our children differs from that of adult in the clinical feature and pathology,while HL of our patients is similar to adults.Since the prognosis of the malignant lymphoma is determined by its pathology,immunohistochemistry plays an important role in the diagnosis and differential diagnosis.J Appl Clin Pediatr,2006,21(3):160-161

Objective To investigate the effects of Zafirlukast on emotions and Th1/Th2 cytokines in asthmatic children.Methods One hundred and eight asthmatic children were randomly allocated to 3 groups.The children in group A inhaled Pulmicort aerosol 200 ?g twice every day.On the basis of inhaled Pulmicort aerosol,the children in group B took orally Zafirlukast orally 10 mg once every day.The children in group C only took orally Zafirlukast 10 mg once every day.The course of treatment of all children were 4 weeks.Anxiety,depression status and the levels of IFN-? and IL-4 in blood serum were respectively detected before and after treatment.Results Scores of anxiety and depression after treatment in 3 groups were significantly lower than those before treatment(Pa0.05).Conclusions Zafirlukast or Glucocorticoid inhalation has the same effect on improving emotional status and accommodating disequilibrium of Th1/Th2 for asthmatic children,but effect of Zafirlukast combined with Glucocorticoid inhalation are better.

Objective To investigate the roles of sphingosine kinase (SPK) on the regulation of proliferation, migration and apoptosis of gastric carcinoma cells. Methods BGC-823 cells were infected with adenoviral carriers bringing the wild type SPK gene and SPK mutant (SPK DN ), and their effect on the migration and 5-FU-induced apoptosis of BGC-823 cells was evaluated. The adenovirus-mediated expression of SPK was detected by Western blot, and cellular SPK enzyme activity was assayed. The cell migration was investigated by Transwell Migration Technology. Results The adenovirus-mediated wild type SPK gene increased the cellular SPK activity, thus leading to enhanced migration and resistance to 5-FU-induced apoptosis of BGC-823 cells. Whereas overexpression of SPK mutant (SPK DN ) decreased the cellular SPK activity, thus inhibited the migration and sensitized BGC-823 to 5-FU-induced apoptosis. Conclusion SPK plays important roles in the regulation of migration and apoptosis of gastric carcinoma cells, therefore it may be of a new target for tumor treatment.

Objective To study the effect of different prostaglandin E2 (PGE2) combined with tumor necrosis factor-?(TNF-?) to the IP3-Ca2+ pathway mediated by membrane TNF-?R of fibroblasts. Methods The lung fibroblasts of breed mouse were primarily cultured. 10 ?g/L TNF-? and 10 ?g/L TNF-? combined with PGE2 of different doses were added to culture medium of fibroblasts. At some observation time,the expression of TNF-?R on the cellular membrane of fibroblasts was detected by the method of immunohistochemistry,the level of IP3 in cells was detected by the method of radioimmunoassay and the contents of Ca2+ in fibroblasts by the method of flow cytometry. Results With doses of PGE2 increasing at 30 s time point and 60 s time point,the cpm value of IP3 of fibroblast decreased gradually. The cpm value of IP3 significantly increased when the dose of PGE2 was 1.0 ?g/L,but obviously lower when the dose of PGE2 was 2.0 ?g/L at 120 s time point. The expression of TNF-?R and the contents of Ca2+ decreased in a dose-dependent way with the dose of PGE2 increasing. Conclusion Certain dose of PGE2 could suppress the effect that TNF-? enhance the cell proliferation of fibroblast by the IP3-Ca2+ pathway mediated by membrane TNF-?R of fibroblasts.

AIM:To investigate the effects of Qili Qiangxin capsule on serum adiponectin ( APN) , serum N-terminal pro-brain natriuretic peptide ( NT-proBNP) and heart function in the patients of coronary heart disease combined with congestive heart failure .METHODS: One hundred and twenty patients were randomly divided into treatment group and control group , and both groups were given anti-failure routine therapy .The patients in treatment group were treated with Qili Qiangxin capsule and the patients in control group were treated with placebo .The patients in the 2 groups were given a certain dose of the drugs for 6 months.The New York Heart Association (NYHA) heart function classification, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD),left ventricular ejection frac-tion (LVEF), and 6-min walking test (6-MWT) were observed before and after treatment .The levels of APN, NT-proBNP were measured by ELISA before and after treatment .RESULTS:With the increase in the class of NYHA heart function , the serum concentrations of APN and NT-proBNP in the heart failure cases increased significantly .After 6-month treat-ment, the effective rate in experimental group was 91.7%and that in control group was 75.0%.A significant difference was found between the 2 groups (P<0.01).After treatment, LVEDD and LVESD in both groups were decreased signifi-cantly, and LVEF in both groups was increased significantly .The serum concentrations of APN and NT-proBNP decreased significantly (P<0.05).6-MWT result was improved significantly.Compared with control group, more obvious effect was observed in experimental group ( P<0.05) .CONCLUSION:Treatment with Qili Qiangxin capsule reduces the levels of APN and NT-proBNP in the patients with coronary heart disease combined with congestive heart failure .
