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 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

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.

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 analysis the relationship between the multipathogens infection and unhealthy pregnancy.Methods　All patients was selectively divided into three groups:group A including 106 patients with unhealthy pregnancy,group B:55 gravidas with normal induced abortion,group C:55 normal parturient with term labor.The ten kinds of pathogens from abortion tissues and placentas were tested by PCR method respectively.Anti-pathogen IgM antibodies were detected by ELISA in the blood specimens.Results　The distribution status of the pathogens were as followed:Human parvovirus B19(B19V 23.6%)＞Cytomegalovirus(CMV,16.0%)＞Toxoplasma (TOX，15.1%)＞Rubella virus(RV，10.4%)＞Ureaplasma urealyticum(9.4%)＞Coxsackie(7.5%)＞Herpes simplex virus(HSV,6.6%)＞Adenovirus,Eprstan Barr virus(3.8%)＞Chlamydia trachomatic(CT 2.8%) in the group A.The positive rates of the pathogens infection in both group C and group B were lower.The positive rates of B19V,CMV,RV,HSV,TOX were significant difference(χ2 test,P＝0.000～P＝0.031) among the three groups,hovever others were not(χ2 test,P＝0.121～P＝0.724).Conclusions　The pathogen infection is an important factor to occur the unhealthy pregnancy,the major pathogens of unhealthy pregnancy are B19V，CMV，TOX，RV，HSV.These pathogens infection should be detected timely in gestational period.

Objective To evaluate the efficacy of endovenous laser treatment(EVLT) plus punctiform stripping therapy for lower extremity varicose veins.Methods Sixty-eight limbs in fifty patients with varicosed vein underwent EVLT plus punctiform stripping therapy in department of vascular surgery of the first affiliated hospital of Anhui medical university.Results All patients were followed for 2～27 months and all the patients had successful occlusions of varicosed veins with no recurrence were observed.Local skin paresthesia were found in 2 patients.No local recurrence and deep vein thrombosis were found.Conclusion EVLT plus punctiform stripping therapy is a simple and effective treatment for lower extremity varicosed veins with fewer complications and recurrences.

Objective To explore the feasibility of off-pump coronary artery bypass grafting (OPCAB) in the treatment of severe coronary atherosclerotic heart disease. Methods Clinical data of 37 cases of severe coronary heart disease from January to December, 2002, were retrospectively reviewed. All operations were conducted under general anesthesia by midline sternotomy. The left internal mammary artery (LIMA) and the great saphenous vein (SV) were divided for grafting. Then we stabilified the local myocardium and exposed the diseased coronary arteries. Following the insertion of an intracoronary shunt, the LIMA was anastomosed to the left anterior descending artery (LAD). Afterwards, the SV was proximally anastomosed to the aorta, and then, to the coronary artery. Results All the operations were completed by beating heart revascularization. The number of bypass grafting was 3 2?0 5 (range, 1～6). Except 1 patient died on the 10th postoperative day, no severe complications, such as peri-operative myocardial infarction, respiratory failure, renal insufficiency or cerebrovascular accident, took place in the remaining 36 patients. Conclusions In the context of skillful procedure techniques and strict peri-operative management, OPCAB in the treatment of severe coronary atherosclerotic heart disease is feasible.
