Elderly acute myeloid leukemia (AML) accounted for 35 % of all AML with the increased incidence year by year, and the median onset age is 67 years old. Generally, AML patients require strong chemotherapy, but older patients often cannot tolerate intense chemotherapy due to the viscera dysfunction. It is still lack of unified treatment clinically. Reports on treatment of elderly AML in the 57th American Society of Hematology (ASH) annual meeting covered multiple fields, in which the traditional induction chemotherapy, demethylation drug alone or in combination with other drugs, and novel drugs were an involved. This article reviewed the latest research on the elderly AML in the 57th ASH annual meeting.

This paper is devoted to discussing two research patterns of biological basis of traditional Chinese medicine syndrome and presenting a research strategy for data mining methods. It points out that data mining methods which are based on feature selection are better fit for investigating biological basis of traditional Chinese medicine syndrome. Based on such a discussion, the concept of "characteristic pattern" is proposed to bridge the gap between "golden index" and biological basis of traditional Chinese medicine syndrome. This paper presents a novel research avenue for investigating biological basis of traditional Chinese medicine syndrome.

Objective:To investigate the relationship between antibiotics use and antimicrobial resistance of Acinetobacter bauman-nii to provide reference for rational antibiotics use. Methods:The DDDs of antibiotics in the inpatients and the drug resistance rate of A. baumannii were analyzed in our hospital from 2010 to 2014. The relationship between the antibiotics use and the antimicrobial re-sistance of A. baumannii was analyzed by SPSS 19. 0. Results:From 2010 to 2014, the total DDDs of antimicrobials in our hospital were decreased year by year in the first three years, while increased significantly in the last two years. The total DDDs of cephalospo-rins always ranked the first and the DDDs of carbapenem were increased year by year. The resistance rate of Acinetobacter baumannii a-gainst multiple antibacterials was increased in varying degrees in the past five years. In addition to levofloxacin, cefoperazone/sulbac-tam and tigecycline, the resistance rate against the other antibacterials was increased up to 50% in 2014. The resistant rate of A. bau-mannii against ciprofloxacin, gentamycin, cefepime, imipenem and tazobactam/piperacillin presented a positive correlation with the DDDs of cephalosporins and quinolones(P<0. 05). The resistance rate of A. baumannii against cefepime, imipenem tazobactam/pip-eracillin and levofloxacin was also positively correlated with the DDDs of carbapenem(P<0. 05). Conclusion: Antibiotics consump-tion is related to drug resistance of A. baumannii,so it is necessary to strengthen the management of clinical antibiotics use to decrease the multidrug-resistant strains.

Objective · To observe the effects of custom made fiber posts on the fracture resistance of young permanent teeth treated with calcium hydroxide for different time. Methods · Forty-five extracted human young permanent teeth (premolar) were selected and randomly assigned to 9 groups.One group was the control group and the rest 8 groups were treated with conventional root canal preparation. Of these 8 groups, 4 groups (F Ⅰ , F Ⅲ , F Ⅵ ,FⅨ ) were restored by custom made fiber posts after being treated with calcium hydroxide for 1, 3, 6, and 9 months respectively, and other 4 groups (C Ⅰ ,CⅢ , C Ⅵ , C Ⅸ ) were not restored by custom made fiber posts. All samples underwent fracture strength tests and their fracture modes were analyzed for the possibility of second repair. Results · The fracture load was decreased with the treatment time after being treated with calcium hydroxide for 1 month (P<0.01). The fracture loads in groups restored by custom made fiber posts were increased after being treated with calcium hydroxide for 6 and 9 months (P<0.05, P<0.01). After being treated with calcium hydroxide for 1 month, groups restored by custom made fiber posts were likely to have fracture modes that facilitate the second repair as compared with groups not restored by custom made fiber posts (P<0.05). Conclusion · The restoration by custom made fiber posts can increase the fracture resistance of young permanent teeth treated with calcium hydroxide for medium and long term ( ≥ 1 month).
