Objective To test the reliability and validity of the collective self-esteem scale for freshman.Methods 800 freshmen finished the Collective Self-Esteem Scale,the Life Satisfaction Scale,and Self-esteem Scale.Results The confirmatory factor analysis shows that collective esteem includes membership esteem,private collective esteem,public collective esteem,and importance to identiy intemal consistency a of the scale and the 4 components of the scale ale between0.6357and 0.8369.All components of the scale except importance to identity have significantly positive correlation with life satisfaction and self-esteem.(0.14＜r＜0.41,P＜0.01).Gids have more scores than boys in total collective esteem(t=3.38,P＜0.01),Private CSE and Importance to Identity (t=3.32,P＜0.01).Conclusion The revised collective self-esteem scale for freshmen has sound reliability and validity.It is a good instrument for measuring collective self-esteem of Chinese freshman.

Raltitrexed is a specific inhibitor of thymidylate synthase,and has been confirmed that ralti-trexed has no cross tolerance with 5-fluorouracil.Studies have shown that raltitrexed-based combination chemo-therapy has a beneficial effect on the treatment of advanced gastric cancer,and well tolerance,which is worthy of clinical use.

Objective;To test the relationship between Collective Self-Esteem,Self-Esteem and Depression,Anxiety.Methods;800 freshmen completed the Collective Self-Esteem Scale,the self-Esteem Sale,Self-Rating Depression Scale and Self-Rating Anxiety Scale.Results;①The rate of slight depression was 21.6%;moderate depression,5.9%;high depression,1.6%.The mean of anxiety was 42,the mode of anxiety was 36.②The predicting effects of Self-Esteem,private collective self-esteem and public collective self-esteem on depression were significant(P

Recently more and more ophthalmologists selected a multifocal intraocular lens (IOL) for their cataract patient in order to get good unaided reading vision. Although the design of IOL have made a great progress, we are still dissatisfied compared with our natural crystal lens. Understanding the design theory and improving our surgery technique are basic for better utilization the multifocal IOL. Does the multifocal IOL reduce contrast sensitivity? Should we implant the multifocal IOL in pediatric cataract surgery? How can we deal with the residual refractive error after multifocal IOL implantation? In this editorial, we try to clarify these problems to make us select and use multifocal IOL better.

Objective To compare extramedullary fixation (EF), intramedullary fixation (IF) and dipolar femoral replacement(DFR) in the treatment of intertrochanteric fractures in the elderly patients. Methods From July 1999 to December 2008, 172 old patients with intertrochanteric fractures were treated by either EF, or IF or DFR. The operative procedures, complications and therapeutic effects were compared between the 3 methods. Results The patients included in the present study were followed up for 8 to 36 months (average, 19. 6 months). There were significant differences ( P<0. 05) in incision length, operation time, intraoperative blood loss, functional recovery and complications between the 3 methods. IF had the shortest incision length and the least intraoperative blood loss. DFR had less blood loss than EF. IF had the least operation time, followed by DFR. DFR had the best functional recovery one year postoperatively. IF had shorter rehabilitation and healing time than EF. Conclusions EF is the first choice for intertrochanteric fractures of A 1.1, A 1.2, A 1.3 and A2. 1. IF is more appropriate for the aged and unhealthy patients with intertrochanteric fractures of A1. 1, A1. 2, A1. 3, A2. 1, A2. 2, A3. 1 and A3.2. DFR is fit for the elderly patients with severe comminuted fractures and osteoporosis.

Objective To compare the clinical effects of endoscopic saphenous vein harvesting and traditional surgical management in coronary artery bypass grafting(CABG).Methods Between march 2007 to June 2008,215 patients underwent CABG.Among them,87 patients underwent endoscopic saphenous vein harvesting.At the same time,128 cases were managed by traditional ways.Results The cases were foUowed up for 1-17 months.Endoscopic great saphenous vein harvesting was superior to traditional management in the healing of wound infection,relief of pain,improvement of edema and skin feeling(P＜0.05).Conclusion Endoscope saphenous vein harvesting is an efficient technique for CABG which is characterized by less trauma and fewer wound complications,and will not influcence the function of vein as well.On the other hand,the satisfaction is improved.

This study was aimed to discuss the distribution and protein expression level ofμ-opioid receptor (MOR) in hippocampus of premenstrual syndrome (PMS) liver-qi stagnation rat model, in order to initially reveal the action mechanism of PMS liver-qi stagnation and intervention effect ofShu-Yu (SY) capsule. Chronic restraint stress method was used to copy PMS liver-qi stagnation rat model.SY capsule ofTiao-Gan prescription was given as intervention. Immunofluorescence (IF) and western blot (WB) technique were used to detect MOR in hippocampal CA1 and CA3 brain area of rats from each group. The results showed that compared with the normal group, the hippocampus MOR distribution arrangement was messy with increased protein concentration in the model group (P< 0.01). After drug intervention, the MOR protein level returned to normal level. It was concluded that the pathogenesis of PMS liver-qi stagnation may be associated with high expression of MOR in hippocampus CA1 and CA3 region of rats. SY capsule can effectively correct and restore it to nearly normal level. It may be one of the central mechanisms in SY capsule treatment of PMS liver-qi stagnation.

Objective To investigate the status of undergraduate nursing faculty's structural empowerment and job satisfaction and to analyze the correlation between themn.Methods Totally 246 nursing teachers were investigated with Conditions for Work Effectiveness Questionnaire Ⅱ and Minnesota Satisfaction Questionnaire.The correlation between structural empowerment and job satisfaction were analyzed by Pearson correlation analysis.Results Undergraduate nursing faculty's total score was (3.04±0.57) points,and score of job satisfaction was (2.93±0.59) points,both of which were at moderate level.Structural empowerment was positively correlated with job satisfaction (r=0.450-0.714,P＜0.01),the higher structural empowerment level,the higher job satisfaction.Conclusions Undergraduate nursing managers can improve nursing teachers' job satisfaction by strengthening the empowerment to nursing teachers,in order to enhance the teaching quality.
