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.

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.

Objective:To analyze and compare the volatile oil in the leaves of Juniperus formosana Hayata from Yuzhong and Lu-qu. Methods:The volatile oil from Juniperus formosana Hayata was extracted by steam distillation, and then identified by gas chroma-tography-mass spectrometry ( GC-MS) . Results:The average yield of the volatile oil from the leaves of Juniperus formosana Hayata from Yuzhong and Lugu was 0. 21% and 1. 45%(w/w), respectively. Between the two areas of the volatile oil from the leaves of Juniperas formsana, totally 40 peaks were separated from the volatile oil from Gansu with 38 ones (95%) were identified. Totally 51 peaks were separated from the volatile oil from Xizang with 47 ones (92%) were identified. The maln constituents in the former volatile oil wereα-pinene(44.92%),l-caryophyllene(9.23%),( -)-isoledene(6. 50%),a-caryophyllene(5.60%),myrcene(4.54%) and d-cadinene(3. 37%), and those in the latter were di-epi-cedrene(31. 87%),cyclohexene(15. 28%),γ-elemene(10. 05%), lanceol (5. 80%) and α-pinene(5. 79%). Conclusion:The constituents in the volatile oil in the leaves of Juniperus formosana Hayata from the two different regions are various, and the differences in the yield and compounds are notable. The method provides reference for the establishment of quality standard for Juniperus. formosana Hayata.

Objective: To study the vitro bioactivity of the Ti-24Nb-4Zr-7.9Sn (TNZS) disks modified by anodic oxidation(AD) and its effects on adhesion of human osteoblast-like MG63 cells. Methods:The TNZS titanium alloy disks were treated with anodic oxidation and the bioactivity was assessed by investigating the formation of apatite on the film surface after soaking in simulated body fluids. The surface composition of the specimens after immersion was evaluated by EDX and X-ray diffraction. MG63 osteoblast-like cells were seeded on the Ti6Al4V,TNZS,AD-TNZS disks, and then the number of attached cells were counted and the cell morphology was examined at each given period. Results:The apatite can form on the treated TNZS disks after soaking in SBF for 6 days. The ratio of attached MG63 on AD-TNZS disks after 60 or 120 min seeding were significant higher than that on other samples and the cells on AD-TNZS disks spread better. Conclusion:The TNZS alloy modified by anodic oxidation can induce apatite formation in SBF and increase the early attachment of osteoblasts.
