Objective:This study investigated 376 adolescents' interpretations to peer rejection events. Methods:Measuring 376 adolescents' degrees of peer acceptance and their interpretations to peer rejection events by means of pen and paper questionnaires.Results:Peer-rejected adolescents presented a similar way of general interpretation to rejected events happened in other peers,however they interpret their own rejected events in a completely different way compared with popular adolescents:The main effects of peer acceptance types were significant on objective and subjective question scores(F(3,344)=3.212,P=0.023;F(3,344)=4.059,P=0.007, respectively);and there was a significant interaction effect of sex?age?peer acceptance types (F(9,344)=3.447, P

This article has shown the experiences to achieve more effective teaching results by integration of multiple teaching patterns,including case-based,problem-based learning,in the teaching of water-electrolyte metabolism and acid-base balance disorders.

Objective To inhibit the expression of matrix metalloproteinase-2(MMP-2) and matrix metalloproteinase-9(MMP-9) in human kidney tubular epithelial cell(HKC) with specific small interference RNA(siRNA),then to observe whether the expression of intercellular adhesion molecule-1(ICAM-1) on HKC could be influenced.Methods HKCs were transfected with MMP-2,MMP-9 siRNA or irrespective siRNA respectively,untransfected HKC was considered as blank control.Four groups of HKCs were stimulated with 100nmol/L phorbol myristate acetate(PMA) for 18h.Total RNA or protein of cells were extracted with Trizol and RIPA cell lysate respectively,the mRNA expression levels of MMP-2,MMP-9 and ICAM-1 were detected by real time PCR,the protein expression levels of above indexes were detected by western blotting and immunofluorescence combined with confocal laser microscopy.Results The specific siRNA could inhibit the expression of MMP-2 and MMP-9 in HKCs effectively.Immunofluorescence combined with confocal assay demonstrated that while HKCs was stimulated with PMA,the expression of ICAM-1 was up-regulated,which was significantly up-regulated in the group transfected with MMP-9 siRNA(P0.05).Conclusions The inhibitory expression of MMP-9 of HKC may up-regulate the expression of ICAM-1,implying that,besides taking part in the degradation of extracellular matrix,MMP-9 may throw an influence on the proceeding of renal fibrosis by inflammatory pathway.

Objective To evaluate the influence of hyperthermia on T helper subgroup (T help type1/T help type2,Th1/Th2) for patients with esophageal carcinoma. Methods 22 patients of esophageal carcinoma were randomly divided into two groups. Both group patients were treated by external radiation, the total dose was 64-66 Gy/30-33 fractions. Radiotherapy was the only therapy method in group A. Hypertbermia was used twice every week, with 8-10 fractions except for radiotherapy in group B. All patients were phlebetomized at the beginning and the end of radiotherapy for examining Th1/Th2 by flow cytometry. Results Th1 was significantly decreased in group A(t = 5.33, P < 0.01). All indexes in group B had no difference (t = - 1.41, P > 0.05). TheThl in group A was decreased much more than that in group B(t = 4.28, P < 0.05). Conclusion Hyperthermia could rectify the balance of Th1/Tb2.

To describe a modified simple iris suture for pupillary dilation technique during vitrectomy in cases with a miotic pupil.Four translimbal incisions were created with a sharp straight blade at 1:30,10:30,4:30,and 7:30 o'clock,respectively.The straight needle of 10-0 polypropylene suture and a Sinskey IOL hook was used to displace the pupillary margin toward the limbus.In 3 cases,four sutures caused a 6-mm to 9-mm square-shaped pupil,and the pupil was allowed to return to a smaller size at the end of the operation.It is simple and may reduce postoperative complications.
