Objective To explore the relationship of college students among death attitude,self-respect,and locus of control character.Methods Death attitude questionnaire,Rosenberger self-respect questionnaire and locus of control Inclination questionnaire were administered to 442 college students chosen by random sampling.Results ①Death attitudes order:death neutrality(3.78±0.62),death escape(2.90±0.77),terror of death(2.71±0.73),approach acceptance (2.49 ± 0.69) and escape acceptance (2.44 ± 0.84).② Different self-respect gradation students displayed significant difference on the terror of death,death neutrality,approach acceptance and escape acceptance (P＜0.05) ;and different character students displayed significant difference on the terror of death,death escape and escape acceptance(P＜0.05).③Self-respect had significant positive correlation with death neutrality (P＜0.01),while had negative correlation with terror of death,death escape,approach acceptance and escape acceptance (P＜0.01);and locus of control character had significant positive correlation with death fear and escape acceptance(P＜0.01).④Self-respect,locus of control character,health condition,discussions over death situation,and meaning of life have a degree of forecasting power over death attitude.Conclusion There is a close correlation among death attitude,self-respect,locus of control character.

In recent five years,brain imaging studies suggested that internet addicts' neural pathway have abnormalities in reward circuits,executive control system,and decision-making system when they are in resting state or induced state.For internet addicts,in the aspect of reward circuits,they showed decreased metabolism level when undergoing a resting-state fMRI scan,and enhanced reward sensitivity as well as decreased loss sensitivity when functioning.In the aspect of executive control system,the related brain areas were associated with reduced white matter integrity and disrupted functional comnectivity in resting-state.When the task was internet-related,internet addicts showed enhanced executive control function.However,when the task was not internet-related,they showed reduced executive control function.In the aspect of decision-making system,reduced cortical thickness in related brain areas was found when internet addicts are in resting-state,and they possess high impulsivity and high risk tendency when they are in induced state.These findings are consistent with the conclusions of substance addicts which are based on the research of brain imaging,therefore,we preliminary think the internet addiction is a new type of addictive mental disorder.

Risk factors of hyperamylasemia in 152 diabetic ketoacidosis(DKA)patients who had no acute pancreatitis were examined.Serum levels of hemodiastase,natrium,kalium,chlorine,calcium,phosphonium,creatinine,carbon dioxide combining power,osmotic pressure,blood glucose,blood lipids and uric acid were measured.With hemodiastase and other 14 factors as independent variables,the multiple linear regression analysis was performed and the partial regression coefficient was estimated.Blood glucose,serum natrium,osmotic pressure and triglyceride entered the regression equation,and their partial coefficients were 10.26,10.35,2.21 and 8.00,respectively.The constant quantitv was -2162.06.Compared with amylase-normal group,hyperamylasemia group showed statistically significant difference in blood glucose,serum natrium,osmotic pressure and triglyceride levels.Higher blood glucose and triglyceride might be the primary causes of hyperamylasemia.

Objective To explore the difference between interval storage and continuous storage of dynamic imagines in contrast enhanced ultrasound (CEUS) quantitative analysis. Methods Two CEUS were performed for each of fifteen participants using interval storage and continuous storage of dynamic images. A number of parameters were analyzed including rising time (RT), time to peak (TTP), mean transit time (MTT), maximum intensity (IMAX), and area under the curve (AUC). The disk usage and time consumpation were also compared for analysis. Results There were no differences in RT, TTP, MTT, IMAX, AUC between the two groups (t=1.028, 1.012, 0.558, 0.223, 0.556, P=0.322, 0.329, 0.586, 0.826, 0.587). There was significantly positive correlations between them (r=0.989, 0.992, 0.867, 0.865, 0.947, all P<0.05). The disk usage in interval storage group was about 1/3 of that in contiunous storage group. And the interval storage method could saved 25-30 min in each case. Conclusion Interval storage is worthy for further clinical application on the groud of its disk usage sparing and less time consumpation without compromising the image quality for analysis.

Objective To evaluate the clinical and radiological results of locking plate for treatment of proximal humerus frac‐tures and the efficacy of anatomical healing of tuberosities .Methods A total of 57 patients with proximal humerus fractures were treated with locking‐plate from July 2008 to March 2012 .A standardized radiological evaluation was conducted .Patients were divid‐ed into two groups :group A (anatomical healing of tuberosities) with 31 cases and group B (without anatomical healing of tuberosi‐ties) with 26 cases .Clinical assessment was performed using the Neer rating scale .Results Considering the entire sample ,the mean Neer score was 87 .96 ± 5 .06 points ,the excellent rate was 94 .74℅ .Comparing these parameters in the two groups ,group A was significant higher in the Neer scores and the range of movement than that of group B (P<0 .05) ,there was no statistic differences in the scores of pain and function (P>0 .05) .Conclusion the locing plate for treatment of complex proximal humerus fractures has a high subjective satisfaction rate .A good functional result depends on anatomical reestablishment of proximal humerus anatomy , particularly the healing of the greater tuberosity .

[ ABSTRACT] AIM:To explore the effect of dexmedetomidine ( DEX) on the CCAAT/enhancer-binding protein-homologous protein ( CHOP) pathway during lung ischemia-reperfusion ( I/R) in mice.METHODS:C57BL/6J male mice were randomly divided into sham operation group ( sham group) , lung ischemia/reperfusion group ( I/R group) , ischemia/reperfusion +normal saline group ( I/R+NS group ) and ischemia/reperfusion+dexmedetomidine group ( I/R+DEX group) .Dexmedetomidine was infused intraperitoneally with 25 μg/kg for 30 min prior to the ischemia period in I/R+DEX group, the normal saline was administrated with the same volume of dexmedetomidine in I/R+NS group.After fini-shed the 3 h-reperfusion period , the left lung tissues were harvested to determine lung wet/dry weight ( W/D) , the total lung water content ( TLW) , and index of quantitative evaluation for alveolar damage ( IQA) .Morphological observation and terminal-deoxynucleotidyl transferase mediated nick end labeling ( TUNEL) were applied to evaluate the structure changes and the apoptosis index (AI) of the lung tissues.The expression of CHOP and glucose-regulated protein 78 (GRP78) at mRNA and protein levels in the lung tissues was detected by Western blot and RT-PCR.RESULTS:Compared with sham group, the W/D, TLW, IQA, AI, the mRNA and protein expression of CHOP and GRP78 obviously increased, and the left lung tissues structure were damaged more obviously both in I/R group and I/R+NS group.Compared with I/R group, the W/D, TLW, IQA, AI and the protein and mRNA expression of CHOP in I/R+DEX group decreased, the injury of the left lung tissue structures induced by I/R in I/R+DEX group were also alleviated .CONCLUSION:DEX alleviates the
lung I/R injury, which may be related to inhibition of apoptosis mediated by CHOP pathway.
