Silent brain infarction (SBI) is mainly diagnosed by brain imaging which is more common in the elderly population.It is considered as the early clinical stage of symptomatic cerebral infarction and cognitive impairment.Its risk factors include age,history of smoking,hypertension,diabetes,metabolic syndrome,carotid atherosclerosis,chronic kidney disease,atrial fibrillation,and obstructive sleep apnea.The related serum biological markers include high-sensitivity C reactive protein,homocysteine,cholesterol,uric acid,and soluble intercellular adhesion molecule-1.This article reviews the advances in research on the imaging characteristics,risk factors,serum biological markers and clinical significance of SBI.

Objective To investigate the relationship among the D-dimer,C-reactive protein and left atrial diameter in the patients with atrial fibrillation(AF). Methods 53 AF patients were selected,the control group consisted of 32 cases of sinus rhythm(SR). The levels of D-dimer, CRP and LAD in AF group were compared with each other, and with those in the control group. Correlation analysis between D-dimer, CRP and LAD were made.Results D-dimer,CUP and LAD in AF group were significantly different from those in SR group. D-dimer and CRP in persistent AF and permanent AF differed significantly from that in SR and paraxymal AF. LAD in the group of persistent AF differed from that in SR group. LAD in permanent AF was significantly different from that in paraxymal AF and SR. Positive linear correlations were found between D-dimer, CRP and LAD in AF (r=0.376; 0.33).Conclusion Hypercoagulable state existsed in AF; the elevation of CRP should be the result and related to persistence time of AF. Positive correlation existsed between LAD and hypercoagulable state and inflammatory reaction.

Objective To compare the impact of the mass effects in situ ( MEIS ) of the sella tumor on neuroendocrine function in children and adolescents with craniopharyngioma before surgery. Methods A total of 227 inpatients with craniopharyngioma in Beijing Tiantan Hospital, Capital Medical University, from October 2009 to October 2014, were retrospectively analyzed. These patients were divided into children group ( n = 167 ) and adolescent group(n=60) according to the age at the time of the first diagnosis. The clinical characteristics and damage degrees of neuroendocrine function by MEIS of sella tumor were analyzed and compared between these two groups before surgery. Result (1) Clinical characteristics of neuroendocrine function:Among hypothalamic dysfunctional manifestations, central diabetes insipidus showed the highest percentage(children group 35. 93%vs adolescent group 31. 67%), followed by the abnormal appetite and obesity ( children group 19. 76% vs adolescent group 28. 33%). The incidences of abnormal body temperature regulation, sleeping disorder, personality abnormality, and cognitive abnormality all were less than 5%. There were no statistical significant differences in the aforementioned hypothalamic dysfunction parameters between two groups (P=0. 524). Among pituitary-target glands dysfunction parameters, growth hormonce ( GH )-insulin-insulin like growth factor Ⅰ( IGF-Ⅰ) axis dysfunction showed the highest percentage ( children group 64. 07% vs adolescent group 50. 0%), followed by pituitary-gonad axis dysfunction in adolescent group (53. 33%), hyperprolactinemia ( children group 31. 14% vs adolescent group 43. 33%), pituitary-thyroid dysfunction(children group 22. 16%vs adolescent group 28. 33%), pituitary-adrenal gland dysfunction(children group 20. 36%vs adolescent group 25%). There were no statistical significant differences intheseabnormalpituitary-targetglandaxes(exceptpituitary-gonadaxis)betweentwogroups(P=0.475). (2) Comparison of damage degrees of neuroendocrine dysfunction: The patients with normal neuroendocrine function accounted for 10. 2%in children group and 8. 3%in adolescent group. The patients with 1 to 4 items of neuroendocrine dysfunction accounted for 75. 6%in children group and 73. 3%in adolescent group. The patients with more than 5 items of neuroendocrine dysfunction accounted for 14. 4%in children group and 18. 4%in adolescent group. There were no significant differences between two groups(Z=-1. 63,P=0. 103). Conclusions There were no significant differences in characteristics and damage degrees of MEIS of the sella tumor on neuroendocrine dysfunction between children and adolescents with craniopharyngioma. It suggests that systematical evaluation on hypothalamus-pituitary-targets axis function is very important for reducing the risks of further neuroendocrine dysfunction in young patients with craniopharyngioma after surgery.

AIM: To isolate peptides targeted binding and internalizing into glioblastoma cell line SWO-38. METHODS: Tumor cells were screened five rounds of whole cell screen through the Ph.D.-12 phage display library. The monoclone specific binding efficiency to the tumor cell was analyzed, and the DNA of phages were extracted, sequenced and translated to the sequences of amino acid. RESULTS: In the phage library after five rounds of screen , 10 of 13 monoclones had highly selective binding to SWO-38 cells. We found two repeated peptide sequences. CONCLUSION: Whole cell screening against tumor cells through random phage peptide library can obtain phage peptides with highly specific binding and internalizing ability. The peptides could be used as a therapy vector for tumor targeted delivery.
