Methods The atherosclerotic plaques in carotid arteries were confirmed by multislice CT angiography(MSCTA),in which serum CRP level were detected in 28 patients with cerebral thrombosis,24 patients with lacunar infarction and 19 patients with TIA in internal carotid artery system in order to analysis the relationship between character of plaque and serum CRP level. Results (1)Mixed plaque and soft plaque were mainly found in cerebral thrombosis and TIA groups, while rigidity plaque was mostly found in lacunar infarction group, there were significance difference in plaques distribution among three groups(all P0.05).(3) CRP level in different groups was (4.546?2.720)mg/L in soft plaque group, (3.951?1.863)mg/L in mixed plaque group respectively,those were both higher than that of the rigidity plaque group[(2.762?1.323)mg/L],and there was significance difference between them(all P

Objective To explore the diagnosis and differential diagnosis of spinal muscular atrophy with respiratory distress type Ⅰ (SMARD1). Method The clinical data, results of gene detection, and follow-up information of a girl diagnosed with SMARD1 were retrospectively analyzed, and related literatures were reviewed. Results The girl was born by cesarean section due to oligohydramnios. After birth, she was transferred to neonatology department for poor feeding and response, and diagnosed with neonatal sepsis, infectious shock, disseminated inravascular coagulation and atypical purulent meningitis. She was discharged after one month of treatment. However, at 2 months old, she presented contracture of ankle joint, abnormal liver function, and myocardial damage. At 6 months old, she had obvious reduced muscular tension and development retardation. At 8 months old, the SMA gene was detected and it was normal. At 9 months old, The panel gene of peripheral neuropathy was detected and found 2 heterozygosis mutations in IGHMBP2 gene, exon8 c.1061-2A>G and exon12 c.1708C>T, which came from her father and mother respectively. Locus of exon12 c.1708C>T has been reported to be associated with the disease, and the other is a shear mutation. The diagnosis of SMARD1 was confirmed by the clinical and gene detection. The girl, 2-year-old now, suffered with recurrent respiratory tract infections, but had no respiratory distress or no respiratory failure yet. Conclusion The clinical phenotype of SMARD1 is complex and diverse. This case is the first domestic case comfirmed by gene detection.

Conclusion The assessment of consonant vowel and tone recognition for cochlear implanted children aged of 3 and above has been modified, and the assessment for those aged 2~3 years old has been developed.

Objective To explore a new peptide-based approach independent of HLA to generate antigen-specific CD+ CD8+T cells. Methods Peripheral blood mononuclear cells(PBMC) were stimula- ted for 6 h with IE-1 peptide pool. Then the activated IFN-γsecreting ceils were tested by immunomagnetic selection. And the selected cells were cultured with radio-inactivated PBMC in medium with 100 IU/ml IL-2 for 4 weeks. Results The generated T cell lines consisted of IE-1 specific CD4+ T (6.88%) and CD8+ T cells 92.99%, which demonstrated antigen-specific killing and cytokine secretion. Conclusion T ceils can be proliferated with this new procedure, and maintain its phenotype and antigen-specific function.

BACKGROUND: Temperament plays an important role in psychological development of children. Generally speaking, temperament is genetically determined, but it is also influenced by some other factors. The influential factors studies of temperament are important to promote psychological development and reduce behavior problems of children.OBJECTIVE: To explore the correlation between breastfeeding and temperamental characteristics in children aged 4-5 years old.DESIGN: Random cluster sampling.SETTING: Affiliated Hospital of Medical College, Qingdao University, Zibo Central Hospital, and Research Institute of Pediatrics, Medical College of Qingdao University.PARTICIPANTS: 737 children (399 males, 338 females) aged 4-5 years old from 8 kindergartens of 4 districts in Zibo were selected from March to June 2005. All the subjects and their parents were informed about the experimental goal.METHODS: With stratified random cluster sampling, 737 children were investigated by NYLS 3-7 years old children temperament questionnaire and self-made inventory questionnaire. The association of 9 dimensions including adaptability, rhythmicity (regularity), activity level, persistence, quality of mood, approach and withdrawal, intension of reaction, distractibility and threshold of responsiveness with feeding type in the first 4 months after birth and duration of breastfeeding was analyzed; the multiple gradual regressive analysis was carried out with each dimension of temperament as the dependent variable and feeding type in the first 4 months after birth and duration of breastfeeding etc. as the independent variables.MAIN OUTCOME MEASURES: Temperamental dimension, feeding categories in the fist 4 months, and breastfeeding duration.RESULTS: All 737 children were involved in the result analysis. Correlation analysis indicated that temperamental adaptability was positively related with formula milk mainly in the first 4 months after birth (r =0.084, P =0.030);Rhythmicity and distractibility were negatively related with formula milk only (r =-0.087, -0.075, P =0.022, 0.047);Activity level were positively related with breast milk only and negatively with both breast milk and formula milk equally (r =0.084, -0.077, P =0.030, 0.045); Approach and withdrawal was negatively related with breast milk mainly (r =-0.097, P =0.012). Rhythmicity, quality of mood and activity level were negatively related with breastfeeding for 4-6 months (r =-0.082, -0.102, -0.153, P =0.036, 0.009, 0.001); Quality of mood and activity level were positively related with the duration of breastfeeding more than 9 months (r =0.089, 0.088, P =0.024,0.025). After rectifying the family structure, and educational level of parents, the influencing factor of adaptability was formula mainly; intensity of reaction was breastfeeding duration for 4-6 months and breast milk mainly;rhythmicity was breastfeeding duration for 7-9 months and formula only; activity level was both breast milk and formula milk equally and breastfeeding duration for 7-9 months; quality of mood was formula only and duration of breastfeeding for 7-9 months; approach-withdrawal was breast milk mainly and both breast milk and formula milk equally; distractibility was formula milk mainly.CONCLUSION: Temperamental development of children aged 4-5 years old is related to feeding type in the first 4 months after birth and duration of breastfeeding; therefore, it is essential to pay attention to breastfeeding during temperamental cultivation and intervention.

Aim DPF2 has been reported to be involved in pathogenesis of leukaemia and oncogenic activity.However,the role of DPF2 in oncogenesis and pathogenesis of pancreatic cancer remains unclear.Therefore,the present research aims to investigate the effects of DPF2-RNAi on proliferation,apoptosis and cell cycle regulation of a pancreatic cell line,PANC-1 cells.Methods The lentivirus-mediated DPF2-RNAi was employed to knockdown DPF2 expression in PANC-1 cells,and the role of DPF2-RNAi in proliferation,apoptosis and cell cycle regulation of the PANC-1 cells was examined through MTT assay,colony formation assay and flowcytometry assay.Results The lentivirus-mediated DPF2-RNAi middle and high doses(2 μL and 4 μL)significantly decreased the expression of DPF2 in the PANC-1 cells.DPF2-RNAi decreased cell viability and colony formation,and increased apoptosis of the PANC-1 cells.Besides,DPF2-RNAi induced the S-phase arrest and decreased G2/M phase population of the PANC-1 cells.Conclusions DPF2 may play a crucial role in proliferation,apoptosis and cell cycle regulation of PANC-1 cells.Knockdown of DPF2 through lentivirus-mediated DPF2-RNAi may provide experimental basis for finding a new method for therapy of pancreatic cancer.

To explore the anticancer effect of curcumin on human B cell non-Hodgkin's lymphoma and compare its effects on human B cell non-Hodgkin's lymphoma cells and normal peripheral blood mononuclear cells (NPBMNCs). MTT assay was used to study the effect of curcumin on the growth of Raji cells and NPBMNCs. The effect of curcumin on the apoptosis of Raji cells and NPBMNC were studied by flow cytometry and TDT-mediated dUTP nick and labeling (TUNEL). The effect of curcumin on the cell cycle of Raji cells were examined by propidium iodide staining flow cytometry. The results showed that curcumin strongly inhibited proliferation of Raji cells, 24 h IC50 for Raji cells was 22.8 +/- 1.82 micromol/L and curcumin induced Raji cell apoptosis in a time- and dose-dependent manner. Raji cells treated with curcumin showed G0/G1 or G2/M phase increase and S phase decrease. However, curcumin did not demonstrate apparent proliferation inhibition and apoptosis induction in NPBMNCs. It was concluded that curcumin is able to inhibit the proliferation of Raji cells by regulating the cell cycle and inducing the cell apoptosis. Morever, curcumin has low toxicity on NPBMNCs but can selectively induce apoptosis in Raji cells.
