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.

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 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.

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.

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 B 19 V,CMV,RV,HSV,TOX were significant difference(? 2 test,P=0 000～P=0 031) among the three groups,hovever others were not(? 2 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 B 19 V,CMV,TOX,RV,HSV.These pathogens infection should be detected timely in gestational period.

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.

Abstract To evaluate the bioavailability of selenium (Se) in Se-yeast to residents with low-Se status, fifty-two youth in a Keshan disease area were randomly divided into three groups, and they were given orally 200 ?g Se daily as So-yeast or sodium selenite, or ordinary yeast for 12 weeks, respectively. Se contents and activities of glutathione peroxidase (GSHpx) in blood were measured at wk 4 and 8 of supplements and 8wk alter the supplements were discontinued. The results show that: 1. the retention of Se in either plasma or erythrocyte is sigificantly higher in Se-yeast than in sodiurn selenite; 2 the effect of Se in Se-yeast is superior to that of sodium selenite for maintaining GSHpx activities; and 3. the relative bioavailabilities of Se in Se-yeast are 556% and 178% when using erythrocyte and plasma Se contents as the response critria, as well as 158% and 116% when estimated by platelet and plasma GSHpx activities. The results indicate that the bioavailability of Se to the residents in a low-Se Keshan disease area is greater when supplemented Se-yeast than selenite.
