Objective To explore mechanism of epigallocatechin-3-gallate (EGCG) on improvement of cognitive function and alleviation of hippocampal insulin resistance in APP/PS 1 transgenetic mice. Method 12 months old female APP/PS 1 mice were randomly divided into 3 groups:model group(Tg), EGCG low dose group (Tg/EGCG-L), high dose group(Tg/EGCG-H). C 57 BL/6 J mice were utilized as control. learning and memory ability in 4 group mice were detected by morris water maze test(MWM). The hippocampal TNF-α/JNK signal and IRS-1 pSer 312 expression were detected by Western blot and immunohistochemical staining. Results Compared with NT mice, Tg mice showed a marked prolongation of the escape latency and swimming distance in the MWM test(P<0.05);Abnormal activation of TNF-α/JNK signaling and increased IRS-1 pSer 312 expression in the hippocampus of Tg mice(P<0.05). EGCG-treated Tg mice showed significantly improvement of all these abnormal changes(P<0.05). Conclusion EGCG treatment is able to alleviate hippocampal insulin resistance and improve cognitive function in the APP/PS 1 mice. which may be partly attributed to the reduction of TNF-α/JNK signaling activity in this AD mouse model.

At the 58th American Society of Hematology Annual Meeting,there were many reports on clonal evolution related with blood disease.Gene mutation and clonal evolution after treatment of azacitidine (AZA) in myelodysplastic syndromes (MDS) were summarized to explore the relationship between clonal evolution and treatment response and clinical process in MDS,and to provide reference for clinical treatment decision.

In comparison with the American Society of Hematology (ASH) annual meeting last year,more studies of hematologic malignancies using next generation sequencing (NGS) are published in the 56th ASH meeting this year.NGS was mainly used in the diagnosis and classification,risk stratification,MRD detection,clonal evolution,prognosis and therapy guidance.This short report will address the application of NGS in the study of hematologic malignancies by summarizing several representative publications from the 56th ASH meeting.

BACKGROUND:Femoral neck fracture combined with femoral shaft fracture as a high-energy injury exhibits some difficulties in its clinical treatment because of bone chips and bone defects. Bone and cel transplantations have been used recently in order to effectively fil the bone defect area. OBJECTIVE:To explore the therapeutic effect of bone transplantation versus cel transplantation for treatment of femoral neck fracture combined with femoral shaft fracture. METHODS: A retrospective analysis was performed in patients with femoral neck fracture combined with femoral shaft fracture, who respectively underwent internal fixation with bone transplantation, tissue transplantation and cel transplantation. Perioperative indexes, incidence of complications and Harris scores were observed and compared. RESULTS AND CONCLUSION: (1) Femoral neck fractures are most commonly classified into Garden type, AO type and Pauwel type. Fracture classification aims to unify standards, which is easy to guide treatment and scientific research. (2) Internal fixation with bone transplantation and tissue transplantation is easy, safe and effective to promote fracture healing and improve hip function, which is an effective way to repair femoral neck fractures with femoral shaft fractures. (3) Compared with autogenous bone graft, alograft transplantation materials as finished products have a variety of sources, and have indications and efficacy similar to non-vascularized bone graft, which are suitable for clinical practice, but long-term effects need to be furtherexplored. (4) Internal fixation with cel transplantation is simple, reliable and effective for femoral neck fractures with femoral shaft fractures, which provides a new idea to reduce the early incidence of femoral head necrosis.

Heart failure is one of the most common acute and critical disease in pediatric,early diagnosis of diseases is an important cli-nical value.The current study found that brain natriuretic peptide(BNP)is a peptide hormone,which is secreted mainly by ventricle and may reflect the state of cardiac function;BNP level of detection is contributive to the diagnosis,treatment of heart failure,etc.J Appl Clin Pediatr,2009,24(1):64-66

Objective:This paper aims to explore the relationship between the residents’ health and economic de-velopment to provide a scientific basis which will promote the coordinated economy and health development. Methods:Adopting the entropy method, we could calculate the comprehensive health evaluation index. In combining the co-inte-gration and error correction models, we could analyze the long-term and short-term relationships between our country residents’ level of health since 2000 and the national macro-economic development information. The Granger causality test served as a good method used in testing the casual relationships. Results: The health and economic development has a co-integration relationship which is -0. 6216 in the short-term correction. The economic development extent is the Granger cause of residents’ health status. Conclusion:There is not only a long-term equilibrium, but also a short-term relationship between the residents’ health and economic development in our country. The economic growth pro-motes residents’ health status while the promotion of residents’ health to economic growth is not obvious.

Objective To investigate the distribution and drug resistance of pathogens for hospital-acquired urinary tract infections between patients in internal medicine wards and in surgical wards .Methods A total of 586 midstream urine samples were collected from patients in the First Municipal Hospital of Qinhuangdao during January 2012 and December 2014.Vitek 2 Compact system was applied in bacteria identification and drug sensitivity tests .Excel and SPSS 11.5 software were applied for data analysis . Results A total of 661 strains were isolated , in which 404 strains were from internal medicine wards and 257 strains were from surgical wards .Escherichia coli (44.6%vs.33.1%) and Enterococcus (23.0%vs. 16.3%) infections were more common in the internal medicine wards (χ2 =8.620 and 4.309, P<0.05), while the occurrence of Pseudomonas aeruginosa infection (4.0%vs.24.5%) was higher in surgical wards (χ2 =63.056, P <0.01).Escherichia coli and Klebsiella pneumonia strains were highly sensitive to piperacillin/tazobactam, cefptetan, amikacin, imipenem, and meropenem, and the sensitivity rates were from 85% to 100.0%.The sensitivity rates of Escherichia coli to ampicillin/sulbactam, levofloxacin and ciprofloxacin were <30%, and strains from surgical wards had lower sensitivity rates to these drug than those isolated from internal medicine wards (χ2 =4.987, 4.575 and 5.359, P<0.05).The sensitivity rates of Klebsiella pneumonia isolated from internal medicine wards to ceftazidime , gentamicin and aztreonam were 68.8%, 60.6% and 69.7%, which were higher than those isolated from surgical wards (36.0%, 32.0%, and 40.0%), and the differences were of statistical significance (χ2 =6.068,4.661 and 5.115, P<0.05).Pseudomonas aeruginosa strains were highly sensitive to piperacillin/tazobactam and amikacin, and the susceptibilities of strains isolated from surgical wards (98.4%and 96.8%) were higher than those isolated from internal medicine wards (75.0% and 81.3%) (χ2 =11.797 and 5.221, P <0.05). Pseudomonas aeruginosa strains isolated from surgical wards were also highly sensitive to cefepime (92.1%), but the sensitive rate of strains from internal medicine wards was only 37.5%, and the difference was of statistical significance (χ2 =24.696, P<0.01).Enterococcus faecium and Enterococcus faecalis were sensitive to tigecycline , vancomycin and linezolid with the sensitivity rates over 95%.Except quinupristin/dalfopristin and tetracycline , the sensitivities of Enterococcus faecalis to other antibiotics were higher than Enterococcus faecium.Susceptibility of Enterococcus faecium from surgical wards (33.3%) to moxifloxacin was lower than those from internal medicine wards (70.8%), and the difference was of statistical significance (χ2 =4.629, P <0.05).Conclusion There are differences in distribution and antimicrobial susceptibility of pathogens isolated from internal medicine wards and from surgical wards .

Objective:To investigate whether the mindfulness training can reduce the aggression level and im-prove the sleeping quality among incarcerated people.Methods:Fifty-four male criminals were recruited into the study.They were divided into mindfulness training group (n =25)and control group (n =29).The training group took mindfulness exercise once a week for 6 weeks.While the participants in waiting list control group waited for 6 weeks without intervention.After 6-week mindfulness training for training group and post-assessment for all partici-pants,the waiting list control group went into 6-week mindfulness training.The Five Facet Mindfulness Question-naire (FFMQ),Aggression Questionnaire (AQ)and Pittsburgh Sleep Quality Index (PSQI)were assessed before and after the intervention.Results:There were 19 valid data in training group,and 21 in control group.After 6-week training,the score difference between pre-and post-assessment of FFMQ (P <0.01 )was higher in the training group than in the control group,and the difference of AQ (P <0.01)and PSQI (P <0.01)was lower in training group than in the control group.Conclusion:The results suggest that 6-week mindfulness training could effectively reduce the aggression level and improve the sleep quality in the long-term incarcerated males.
