Objective:To investigate the inhibition control characteristics in college students with mobile phone addiction,then to design tactics to enhance their inhibition control ability.Methods:Totally 150 college students were surveyed with the Mobile Phone Addiction Index (MPAI)to filter out the high and low mobile phone addiction.Thirty students with more than eight affirmative answers to the seventeen MPAI items were selected as the mobile phone addiction group while another 30 students with less than eight affirmative answers were selected as non addicts group of MPAI.All participants were asked to complete task of stop signal.Results:In college students with mobile phone addiction,the stop-signal reaction times were longer than that in the students without mobile phone addiction [(292.0 ±89.4)ms vs.(241.1 ±95.7)ms,P <0.05],while the non-signal reaction times were shorter than that in those without mobile phone addiction [(494.2 ±103.8)ms vs.(597.6 ±108.9 )ms,P<0.01].Conclusion:It suggests that the college students with mobile phone addiction may have poorer inhibitory control.

Objective To study the intracellular calcium ([Ca2+ ]i) in myocardial cell of obesity rats induced by high-fat diet. Methods Male Sprague-Dawley (SD) rats were divided into obesity resistant (OR, n=15), normal (Nor, n=15) and obesity prone (OP, n=15) group after fed with high-fat diet for 10 weeks. Their body fat and serum lipids were measured. Myocardial cells were isolated with Langendorff perfusion and [Ca2+]i was measured with calcium indicator Fluo-3/AM and laser scanning confocal microscope after KCl depolarization and caffeine- induced. Results Compared with those in Nor and OR rats, the epididymal fat, perirenal fat, omental fat and body fat increased in OP rats (P<0.05), as well as the the level of total cholesterol, triglyceride and low density lipoprotein (P<0.05); the vary of [Ca2+]i elevation and restoration were lower (P<0.05). Conclusion The vary of [Ca2+ ]i elevation decreases in OP rats after KCl depolarization and caffeine-induced, that may associated with arrhythmia in obesity rats.

Objective Few prospective data are currently available on acute gastrointestinal hemorrhage (AGIH) as a complication in acute kidney injury (AKI).The aim of the present study was to find out clinical characteristics,incidence,etiology,risk factors,and outcome of AGIH in patients with AKI.Methods We performed a prospective study on an inceptione cohprt of 512 patients admitted for AKI in our hospital.Data on clinical risk factors for bleeding,frequency of occurrence of AGIH,in-hospital mortality were collected,and independent predictors of AGIH were identified.Results A total of 53 patients had AGIH as a complication of AKI,and 45 were upper AGIH.Fifteen patients had clinically severe bleeding.Independent baseline predictors of AGIH were severity of illness,cardiac failure,mechanical ventilation,low platelet count,chronic hepatic disease,liever cirrhosis,severe AKI.Inhospital mortality was 52.8％ in patients with AGIH,and 22.2％ in the other patients.AGIH was significantly associated with an increase in hospital mortality.Conclusions AGIH are frequent complications of AKI.In this clinical condition,AGIH is more often due to upper gastrointestinal bleeding and is associated with a significantly increased risk of death.Both renal and extrarenal risk factors are related to the occurrence of AGIH.
