Objective To evaluate the merits and demerits of three different closure methods for femoral artery access site in the interventional therapeutic procedures for senile patients with coronary artery disease. Methods We managed the femoral artery access sites in 60 cases undergoing interventional operation using three different hemostasias, including manual compression, Femostop equipment and Perclose suture (20 cases for each group). The procedure time, time for patients staying in bed, expenditure obedience, the percentage of procedure failure and vagal vascular reflex, and local vascular complications were observed and analyzed statistically. Results The study showed that the procedure time in Perclose suture group was about 12 minutes, much shorter than that in finger pressing and Femostop equipment groups (respectively 23 and 55 minutes, P

Sensitivity toward pictorial sexual information was tested implicitly in 448 servicemen from four different arm services and 86 civilians. 20 pairs of pictures containing sex information for sensitivity test were screened out in prior-experiment, and then they were exposed to the test subjects with a 500 ms duration, in order to find out the difference in the subjects' preference in selecting sexual and non-sexual information pictures. The result showed that, compared with the civilians, all the four groups of servicemen showed stronger inclination in selection of sexual information pictures, however there was no group difference or gender difference. The results also suggested that, implicit experiment with paired pictures could be one kind of reliable and effective method in studying sex information sensitivity.

In order to study the mental health status of military personnel under settings of special military operations, 1 263 officers and crew of a submarine base, 361 officers and crew of a naval base and 753 officers and soldiers of a missile base were subjected to SCL-90 scale evaluation. The results were compared with mililary norms and civilian norms. It was revealed that SCL-90 of all the members of three groups had higher scores on every factor compared with the eivilion norms. Besides somatic factors, the scores of other factors were also higher than that of military norms. The results suggested that certain special military operation settings could exert negative impact on the mental health status of military personnel. An analysis of the results also showed that the greatest impact was found in submarine and naval officers and crew, as well as in missile troops, indicating that highly enclosed settings could strongly influence the mental health of individuals.

Objective To explore the relationship of personality and coping style between parents and male inpatients with internet addiction disorder. Methods 51 male inpatients with internet addiction disorder and their parents were investigated with Cattell 16PF and Coping Style Questionnaire to evaluate their personality and coping style. All data were analyzed by partial correlate analysis. Results Multi-factors of 16PF( warmth, reasoning, emotional stability, dominance, vigilance, sensitivity, abstractedness, privateness, openness to change, perfectionism, apprehension, tension ) of male inpatients were significantly correlated with father' s ( r = 0.72 ～ 0. 85 or - 0. 71 ～ - 0.93 ) or mother' s 16PF( r = 0.73 ～ 0.92 or - 0. 72 ～ - 0.81 ), bu+ non of those factors corrected with the same factor of parental. Male inpatients' coping style did not corrected with father' s, but their problem sloving, rationalization and self-accusation corrected with mother's seeking support, rationalization and avoidance respectively. Conclusion The personality of male inpatients with internet addiction disorder is affected by parental personality, but under the impact of internet addiction disorder, this kind of influence is weakened. In coping style, the father' s influence is far weaker than the mother' s, suggesting that there is father function flaw during the process of those inpatients growing up.

ObjectiveTo investigate current situation of creativity among inpatient high school students with internet game addiction disorder (IGAD) and its influential factors.MethodsThe participants comprised the patients in the General Hospital of Beijing Military Region meeting the diagnostic criteria for Internet Addiction( including 70 cases of high school (HSIGAD) and junior high school 65 cases (JHSIGAD) and 70 cases of high school in the school (HSIS) ).Questionnaire plus clinical interview method was used in the process of investigation,and the research tools include diagnostic criteria for Internet Addiction,Creativity Assessment Packet (CAP).And further Family environment questionnaire,Egna Minnen av Barndoms Uppfostran (EMBU) and 16PF were used for HSIGAD.ResultsThe creativity's total and each factor's score of HSIGAD( creativity's total ( 109.60 ±11.12 ),risk ( 23.77 ± 2.97 ),curiosity ( 31.51 ± 4.29 ),imagination ( 26.06 ± 3.57 ) and challenge ( 28.26 ±2.87) ) were lower than that of HSIGAD( ( 111.35 ± 12.00) (24.14 ±3.20) (32.25 ±4.26) (26.35 ±4.25)and (28.62 ±2.79) respectively),but there was no significant difference.The creativity's total and each factor's score of HSIGAD were significantly lower than that of HSIS( ( 121.27 ± 7.68 ) ( 26.17 ± 2.30) ( 35.80 ± 3.11 )(29.66 ±3.28) and (29.64 ±2.34) respectively) (P＜0.01).Multiple stepwise regression analysis found that extroversion in personality and knowledge in family environment entered the regression equation,and all had positive prediction for creativity tendency.ConclusionThe internet game addiction may slow the development of high school student's creativity.While the personality of extroversion and the family environment with esteem to knowledge were beneficial to the development of adolescent creativity tendency.

Objective: To study the effect of enalapril on inducible atrial fibrillation(AF) in old rats. Methods: Old male Wistar rats were randomly divided into control group(n = 12) and experimental group(n = 13). Rats in control group were fed routinely. Rats were fed with enalapril besides normal diet in experimental group for three months. Rats were then anesthetized, thoracotomy was performed and pericardium was opened to expose heart. Right atrium effective refractory period(ERP) was measured. Sinus conduction time (SCT) and sinus recovery time (SRT) were measured for evaluating sinus function. Interatrial conduction time(IACT) and atrium response to burst pacing were evaluated in vivo. Plasma angiotensinⅡ level and atrial tissue angiotensinⅡ level were determined by radioimmunoassay. Sections were cut from the tissue of atrium and stained with Masson trichrome. The ratio of the area occupied by interstitial to the total area was measured. Results: Contrast to control group,IACT and SRT were shorter in experimental group(P ＜ 0.01 and P ＜ 0.05 respectively). AF were induced in 9 rats in control group and 4 rats in experimental group(P ＜ 0.05). AngiotensinⅡconcentration was significantly decreased in right and left atrium tissues of experimental group compared with that in control group(P ＜ 0.01). A significant decrease in interstitial atrial fibrosis was presented in experimental group compared with that of control group(P ＜ 0.01). Conclusion: Inducible atrial fibrillation rate was decreased in old rats after treatment with enalapril. This effect maybe resulted from the inhibited local atrium renin-angiotensin system and improved sinus node function by enalapril.

With the rapid development of tumor subjects and the advance of medical technology,tumor mortality is declining in spite of the increase in tumor incidence.The male survivors pay more and more attention to their prognosis to improve the quality of their life.In the meantime,whether they could produce their own offspring become the main concern of tumor patients with good prognosis.However,until now,male tumor patients,their relatives,different social sectors and even some of our health workers,havent noticed the importance of fertility preservation and long-term fertility desires of male patients with tumor which will lead to declined or even irreversible sterility induced by the lack of fertility preservation before anti-tumor therapy.It's an important way to do fertility counseling,learn the risk of their treatment plans and choose the appropriate technique of fertility preservation which will improve prognosis quality of life of male tumor patients.This article will review the effects of tumor and the treatment on male fertility,their subjective needs and concerns,main methods for fertility preservation and the domestic and foreign research present situation.

Objective To investigate the effects of ciyelosporine-A(CsA).a calcinenrin(CAN)inhibitor,on electrophysiological propertiesof atria in canine tachycardia-induced model of AF.Methods Eighteen healthy adult mongrel canines weighing 17.0 to 23.2 kg(rangedfrom 2 to 4 years old)were randomized to 3 groups,Sham group(no pacemaker was implanted),atrial tachypacing group(ATP group)each group at baseline and after 8 weeks' tachypacing.Measurements included atrial effective refractory period(AERP),conductionvelocity(CV),wave length(WE),atrial fibrillation load and rate-adaptability. Results After 8 weeks' atrial tachypacing,ATP andCsA groups showed significant longer duration of the P wave,shorter AERP,decreased adaptation of AERE slower CV,shorter Wland longer AF duration compared to the shamg roup (all P＜0.05).AERP of the CsA group was longer than that of ATP group (P＜0.05),but there were no differences in rate-adaptability,CV,incidence of induced AF and AF duration between CsA group and ATP group.Conclusions Our results suggest that calcineurin pathway intervention by CsA have a positive effect on tachycardia-inducedelectrical remodeling of atria,but can not prevent or reverse AF.

Objective To determine whether sleep-disordered breathing (SDB) may lead to nocturnal myocardial ischemia and whether the severity of this ischemia may be relieved by nasal continuous positive airway pressure (CPAP). Methods Overnight polysomnogram examination and simultaneous 3-channel Holter monitoring were performed on 76 patients with moderate to severe SDB and no history of coronary heart disease. All the cases were treated with CPAP for one night. ST depression was defined as a ST segment decrease of more than 1 mm from baseline and lasting 1 min or more. The total duration (minutes) of ST depression was indexed to the total sleep time (minutes per hour of sleep). Results Twenty-eight patients (37%) showed ST segment depression during their sleep. Before CPAP treatment, the respiratory disturbance index (RDI) and arousal index were significantly higher during periods of ST depression than when ST segments were isoelectric, whereas no significant difference was found in blood oxygen saturation (SaO2). After the CPAP treatment of patients with ST depression, the duration of ST depression was significantly reduced from 36.8±18.9 to 11.4±13.2 min/h (P＜0.05). ST depression-related indexes, including RDI, arousal index and the percentage of sleep time spent at SaO2 below 90% (TS90/ TST), were all significantly decreased, with RDI from 63.4±23.8 to 8.1±6.6 /h, arousal index from 51.2±18.9 to 9.6±5.4 /h, and TS90/ TST from 50.6±21.4 to 12.9±14.7% (P＜0.05). Conclusion ST-segment depression is rather common in patients with moderate to severe SDB, and CPAP treatment can significantly reduce the duration of ST depression. ST depression in these patients may reflect the myocardial ischemia that really exists and the non-ischemic changes associated with recurrent SDB.

Background and Objectives The relationship between left atrial (LA) size and congestive heart failure (CHF) is well recognized;however, there is little information on the association of pulmonary vein (PV) diameter and CHF.The purpose of this study was to investigate the changes of PV and LA sizes in CHF patients by multislice computed tomography (MSCT) angiography using a new 64-slice scanner. Methods and Results We assessed diameters of PVs ostium and LA by 64-slice MSCT with three-dimensional reconstruction in 25 CHF patients and in 26 age- and sex-matched non-CHF controls. Compared with controls, CHF patients showed significant greater diameters of left superior pulmonary vein (LSPV) and right inferior pulmonary vein (RIPV) in both anteriorposterior(AP) and superior-inferior (SI) directions (P＜0.01), significant dilation of right superior pulmonary vein (RSPV) in AP direction (P＜0.05), as well as significant increase of LA transverse, AP, and SI diameters (P＜0.01). Conclusion Significant dilation of PVs with simultaneous LA enlargement was demonstrated in CHF patients. This anatomic and geometric changes may participate in the perpetuation of AF.
