Objective To determine the effects of a 12-week aerobic exercise program on brachial-ankle pulse wave velocity ( baPWV) in sedentary and under-exercised healthy older adults. Methods A total of 35 sedentary and unfit but healthy older adults with mean age of 74.7 years were randomly assigned to a progressively increased intensity aerobic exercise group ( n = 17) or a control group ( n = 18). The exercise group performed aerobic exercise 3 times each week for 12 weeks. The control group didn't participate in the exercise program. Heart rate,blood pressure and baPWV were evaluated at admission to the aerobic exercise program and at the end of the 12 weeks in both groups. Results The mean baPWV in the aerobic exercise group decreased from 15.88 m/s to 14.62 m/s after exercise, a significant reduction. Blood pressure in the exercise group showed a decrease which was not significant. No significant improvement was identified in the control group. Conclusions Only 12 weeks of aerobic exercise with progressively increased intensity can improve arterial elasticity in sedentary and unfit older adults.

Objective To summarize the perioperational nursing strategies for patients undergoing mandibular defect repair by forearm flap composite fibula flap.Methods From January 2009 to December 2012,9 patients with mandibular defect and soft tissue defects after resection of malignant tumors received fibula flap and forearm flap.Before operation,the patient received psychological education and the preparation of donor flap and receptor area together with oral preparation was performed.After operation,the vital signs and blood circulation in the flap were observed.Results The fibula and forearm flaps in 8 patients survived.The fibula flap in one patient survived while the forearm flap developed with vascular crisis.The success rate for the transplanted flap was 89.9%.

AIM:To investigate the protective effects of adenosine on cultured rat hippocampal neurons after oxygen-glucose deprivation. METHODS:The control and adenosine-treated hippocampal neurons cultured for 12 d were exposed to oxygen-glucose deprivation environment for 0.5-4 h and then cultured with original medium in normoxia for 24 h . The soma area,survival rate, effluxes of lactate dehydrogenase (LDH)and apoptosis of neurons were observed. RESULTS:The soma area, effluxes of lactate dehydrogenase from neurons and apoptosis were increased while survival rate of neurons was decreased after oxygen-glucose deprivation compared with those pre-oxygen-glucose deprivation. Compared with the control, after oxygen-glucose deprivation the soma area, effluxes of lactate dehydrogenase from neurons and apoptosis were decreased, however, the survival rate of neurons was increased in the adenosine group.CONCLUSION: Oxygen-glucose deprivation can lead to the severe damage of cultured hippocampal neurons, and adenosine can reduce neuronal injury induced by oxygen-glucose deprivation.

AIM: To determine the effects of NF-?B on the development of rat pancreatic fibrosis mediated by angiotensin II. METHODS: Spraque-Dawley rats (200-300g) were randomly divided into normal group, control group and losartan-treatment group. Pancreatic fibrosis was induced by injection of 2% TNBS into biliopancreatic duct. Rats in losartan-treatment group and control group were respectively treated with losartan (10 mg?kg~(-1)?d~(-1)) by gavage and the same volume of saline vehicle. The expression, distribution, and activation of NF-?B were studied by Western blot, immunohistochemistry and TransAM~(TM). Toluidine blue staining and transmission electron microscopy were also used to observe the number, distribution and degranulation of mast cells. In addition, RT-PCR was performed to detect the intrapancreatic ICAM-1 mRNA expression. RESULTS: The expression and activity of intrapancreatic NF-?B p65 protein were significantly increased on day 3 after operation, reaching peak on day 7 [(0.406?0.086) mg/g total protein]. Mast cell activation was observed and ICAM-1 mRNA levels on day 3 and 7 were up-regulated in control group. Losartan treatment inhibited NF-?B expression and activation, reduced mast cell infiltration and degranulation and decreased ICAM-1 mRNA expression compared with control rats. CONCLUSION: It might be associated with the expression and activation of NF-?B that angiotensin II mediates inflammation and fibrosis in the early stage of pancreatic fibrosis. [

AIM: To examine the effects of PPAR? activation on the growth of human pancreatic carcinoma in vitro and to explore the role of NF-?B and activator protein-1 (AP-1) in this process. METHODS: SW-1990 pancreatic cancer cells were treated with ligand of RXR?, 9-cis-RA, ligand of PPAR?, 15d-PGJ_2, and both. Antiproliferative effect was evaluated by using MTT assay; the expression of NF-?B p65 active protein was assayed by using TransAM~TM technique. Expression of c-jun and c-fos by SW1990 cells, which were treated with 15d-PGJ_2, 9-cis-RA and both at varying concentrations, were detected by RT-PCR. RESULTS: MTT assay demonstrated that 15d-PGJ_2, 9-cis-RA and the combination of both had a potent inhibitory effect on the growth of SW1990 cells in a dose-dependent manner. 9-cis-RA had a synergic action with 15d-PGJ_2 on the growth inhibition of pancreatic carcinoma. TransAM~TM showed a down-regulation trend of P65 active protein in SW1990 cells treated with 15d-PGJ_2, 9-cis-RA and both. RT-PCR demonstrated that the expression of c-jun mRNA in 15d-PGJ_2, 9-cis-RA and the combination of both-treated cells were firstly increased and then decreased, the expression of c-fos was decreased in 15d-PGJ_2 or 9-cis-RA treated SW1990 cells, but increased in cells treated with both 15d-PGJ_2 and 9-cis-RA. CONCLUSION: Activation of PPAR? exerts a negative regulatory effect on the growth of pancreatic carcinoma in vitro. Activation of RXR? has a synergic action with PPAR? agonist. The mechanism is probably associated with down-regulating the expression of NF-?B and AP-1. [

Objective To investigate the effect of penehyclidine hydrochloride on the cell apoptosis in lung tissues in a rat model of traumatic acute lung injury (ALI) .Methods Fifty-four SD rats weighing 225-275 kg were randomly divided into 3 groups ( n = 18 each) : control group (group C) , ALI group, penehyclidine hydrochloride group ( group P) . Traumatic ALI was induced by dropping a self-made impact device on the chest of anesthetized rats according to the technique described by Raghavendran et al. Intraperitoneal penehyclidine hydrochloride 2 mg/kg was injected immediately after blunt chest trauma and at 12 h after blunt chest trauma in group P. Six rats in each group were sacrificed at 3, 12 and 24 h after blunt chest trauma and the lung tissues collected for microscopic examination and determination of cell apoptosis (by TUNEL) and expression of Bax and Bcl-2 (by immuno-histochemical staining) . The apoptosis index was calculated. Results The apoptosis index and expression of Bax and Bcl-2 were significantly higher, while the ratio of Bcl-2/Bax was significantly lower at each time point in groups ALI and P than in group C ( P ＜ 0.05) . The apoptosis index and Bax expression were significantly lower,while the Bcl-2 expression and ratio of Bcl-2/ Bax higher at each time point in group P than in group ALI.The microscopic examination showed that penehyclidine hydrochloride injection significantly attenuated the pathologic changes. Conclusion Penehyclidine hydrochloride can reduce the traumatic ALI through inhibiting the cell apoptosis in rat lung tissues.
