3.The mechanism study of EGCG on improvement of cognitive function and alleviation of hippocampal insulin resistance in APP/PS 1 transgenetic mice
Chinese Journal of Biochemical Pharmaceutics 2014;(1):12-15
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.

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.

Objective To investigate the relationship between interleukin 1β( IL?1β) , interleukin?33 ( IL?33) , neutrophil?to?lymphocyte ratio ( NLR ) and atrial fibrillation. Methods Eighty?two patients with nonvalvular atrial fibrillation treated in the department of cardiology in the Fourth People′s Hospital of Jinan from October 2015 to October 2016 were enrolled in the study,including 43 patients with persistent atrial fibrillation and 39 patients with paroxysmal atrial fibrillation. 50 healthy subjects were selected as the control group. Enzyme linked immunosorbent assay (ELISA) was used to determine the concentration of IL?1βand IL?33,and the left atrial diameter ( LAD) was measured by echocardiography. Results ( 1) The concentrations of IL?1β,NLR and LAD in the paroxysmal atrial fibrillation group were (24. 44±4. 89) ng/L,(2. 51±1. 22) %,(36. 16± 6. 12) mm,the concentrations of IL?1β,NLR and LAD in the persistent atrial fibrillation group were (26. 95±5. 86) ng/L,(5. 7±1. 8) %,(39. 36±4. 78) mm and the values in the control group were (19. 53±4. 51) ng/L,(1. 82 ± 0. 41 ) %, ( 33. 31 ± 2. 89 ) mm, respectively. The differences among the three groups were statistically significant ( F=16. 74,11. 82,14. 85,P<0. 01) . The indexes of paroxysmal atrial fibrillation group and persistent atrial fibrillation group were higher than those of the control group ( P<0. 01 ) . ( 2 ) In the persistent atrial fibrillation group, NLR and LAD were ( 5. 7 ± 1. 8 )% , and ( 39. 36 ± 4. 78 ) mm, higher than those of the paroxysmal atrial fibrillation group ( (2. 51±1. 22)%,(36. 16±6. 12) mm),the differences were statistically significant ( P<0. 01) . However,the level of IL?1βin the persistent atrial fibrillation group was not significantly different from that in the paroxysmal atrial fibrillation group ( (26. 95±5. 86) ng/L vs. (24. 44±4. 89) ng/L,P>0. 05). (3) The concentrations of IL?33 in the paroxysmal atrial fibrillation group,atrial fibrillation group, control group were ( 48. 31 ± 4. 72 ) ng/L, ( 50. 03 ± 2. 18 ) ng/L, ( 56. 87 ± 5. 12 ) ng/L, respectively. The difference among the three groups has no statistical significance ( F=2. 52, P>0. 05 ) . ( 4 ) NLR level was positively correlated with LAD ( r=0. 32,P=0. 002) . There was no significant correlation among IL?1β,IL?33 and LAD ( r=0. 16, P=0. 11, r=0. 02, P=0. 37 ) . Conclusion The levels of IL?1β, NLR and LAD in peripheral blood of patients with atrial fibrillation were significantly higher than those in patients with sinus rhythm,and there was a positive correlation between NLR and LAD.
