Objective To evaluate the effects of TMS on the brain plasticity and functional outcome after cerebral infarction in rats. Methods Twenty-four male Sprague-Dawley rats were divided randomly into a model group and a TMS group. The rat models of focal cerebral infarction were established with unilateral middle cerebral artery (MCA) suture occlusion method. The rats of TMS group were given additional 4 weeks of TMS treatment commenced at!1 day after infarction (2 times per day, 30 pulses per time), while those in the control group were reared in their original living state. Synaptic substructure in the sensori-motor cortex area was assessed morphologically and quantitatively. Results When compared with the model group, the rats in the experimental group had a significant improvement in terms of their neural functions (P

Objective To study the effects of transcranial magnetic stimulation (TMS) on the expression of c-Fos and brain-derived neurotrophic factor (BDNF) of the cerebral cortex in rats with cerebral infarction. Methods Cerebral infarction models were established by using of left middle cerebral artery occlusion (MCAO) and randomly divided into a model group (n=40) and a TMS group (n=40), in additional, TMS treatment (2 times per day, 30 pulses per time) with frequency of 0.5 Hz and magnetic field intensity of 1.33 Tesla was carried out in TMS group after infarction. The expression of c-Fos and BDNF was measured at 1 d, 7 d, 14 d, 21 d and 28 d after infarction, respectively. Results The positive expression c-Fos and BDNF was detected in the cortex around the infarction areas, while the expression of c-Fos and BDNF was increased significantly in TMS group in comparison to those in model group at 7 d, 14 d, 21 d, 28 d (P

Objective To investigate the clinical benefits and the impacts on distribution and antibiotic resistance of pathogenic bacterium associated with fluoroquinolone prophylaxis during neutropenia in patients with acute leukemia.MethodsA total of 62 infection episodes occurred in patients with acute leukemia were retrospectively analyzed from October 2013 to October 2015.The patients admitted in ward A (group A,n=31) received Cephalosporin drugs as contrast, and received quinolones in ward B (group B,n=31).ResultsTo observe the implementation of quinolones in treatment of patients, the bacteria decreased significantly, the Klebsiella pneumoniae was the most common, but compared with the control group, there are still differences (P<0.05, and the observation group of patients with oral ulcer infection rate was 9.68%, upper respiratory tract infection rate was 6.45%, the infection rate of lung 6.45%, the digestive tract infection rate was 6.45%, the infection rate was 3.23%, perianal skin infection rate was 3.23%, the infection rate was 3.23%, which is significantly lower than the control group (P<0.05, and the observation group of patients with severe neutropenia, duration of neutropenia lack degree is significantly better than the control group (P<0.05).ConclusionThe fluoroquinolone prophylaxis induces diminishing proportion of normal flora and increasing frequency of Escherichia coli in severely neutropenic patients with acute leukemia,may not influence the distribution of other bacteria.The susceptility of main pathogens may not be affected by antibiotic prophylaxis.The fluoroquinolone don't decrease the incidence of septicemia and infection in gastrointestinal tract.Our data suggest that more prudent use of antibiotic prophylaxis may be reasonable even in patients at high-risk for developing infection.
