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

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.

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.

AIM: To investigate the anti-cancer effect of cytotoxic T lymphocytes (CTL) activated by sensitized dendritic cells (DCs). METHODS: Immature DCs were induced in vitro from peripheral blood monocytic cells (PBMC) and sensitized by adding tumor cells antigen extract. DCs were identified by their morphology and surface markers. MTT assay was used to evaluate the killing activity of CTL activated by sensitized DCs. The effects of specific CTL cells on inhibiting transplanted tumor HT-29 growth and on preventing HT-29 tumor generation were evaluated by injecting CTL into nude mice. RESULTS: After cultured for seven days, a large number of activated DCs were obtained with typical morphology, extensive stimulatory proliferation capacity and high CD80 (63.5%), CD83 (67.6%) and CD3/HLA-DR (83.2%) expressions. The killing activity of CTL at 20∶1 ratio of effective cells to target cells was more than 75% to tumor cells, 35%-45% to homologous cell line and weaker to other germ cell line (P

Objective To evaluate the diagnostic value of 128-slice spiral CT angiography( MSCTA)for bypass grafts in patients after coronary artery bypass grafting(CABG).Methods One hundred and thirty-three bypass grafts (44 IMA grafts,89 saphenous veins grafts) of 46 patients after CABAG operation for 12 to 76 months were examined by MSCTA.Then the coronary angiography(CAG) was performed on those patients 3 - 10 days after MSCTA examination.The MSCTA results were compared with the angiography results.Results Among the 133 bypass grafts,MACTA examination showed that 17 grafts were occluded and 20 grafts were severe restenosis( restenosis degree ＞ 50％ ).There was also 17 occluded grafts showed in CAG examination as in MSCTA results.But 21 restenosis ( restenosis degree ＞ 50％ ) bypass grafts were identified by CAG.Compared with the CAG results,there was 1 false positive and 2 false negative in the MSCTA results.The overall sensitivity and specificity of MSCTA on evaluating the bypass grafts were 94.7％ and 98.9％.The positive predictive value and the negative predictive value were 97.3％ and 97.9％,respectively.Conclusion As a noninvasive examination,128-slice spiral CT could accurately identify and evaluate the bypass grafts lesions after CABG.

Objective To evaluate and screen the concentration and coordination degree of the opinions of the experts in TCM pediatrics on the preventive method of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy;To formulate scientific and practical methods for perfume pouch wearing in this book. Methods Delphi method was applied to this research. All questionnaires were designed based on the literature research and distributed to more than 30 experts for 3 rounds. And the results in the first two rounds of survey were analyzed. Results Totally 31 and 33 valid questionnaires were received in the first and second time respectively. The experts’ activity index was 88.6% and 93.4% respectively. The perfume pouch wearing methods of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy was set down. And most of the experts shared a positive view on the concentration and coordination degree of this book. Conclusion The experts’ opinions upon this draft are quite positive. The experts are from all over China, and they are quite professional, with representativeness. The perfume pouch wearing methods of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy are generally recognized by the experts. However, there are still some different ideas in terms of some indexes, which need to be further discussed.

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.
