Objective: To evaluate the reliability and validity of the inventory of experience of close relationship-revised version (ECR-R).Methods:286 college students were collected for testing the internal consistency and structure validity of the inventory. Test-retest reliability was founded in 31 students. Criteria validity was also studied in 32 cases with anxiety neurosis. Results: The Cronbach ? of the ECR-R and its two subscales (anxiety and avoidance) were 0.87, 0.86 and 0.81 respectively. The test-retest reliabilities of them were 0.75, 0.82 and 0.61 respectively. The two subscales had good discriminating ability and were confirmed by factor analysis, anxiety and avoidance could explain 21.28 and 11.20 of the total variance. Conclusion: The ECR-R is psychometrically acceptable and may be applied to study attachment of Chinese adolescents.

Objective To investigate the self-assembly and cellular localization patterns of fila-mentous temperature-sensitive protein Z (FtsZ) in Escherichia coli (E.coli) strains by using FtsZP74R, FtsZG77D and FtsZA81R mutants.Methods YFP or His labeled FtsZ proteins and the plasmids of FtsZ mu-tants were constructed by using molecular clone and site-directed mutagenesis methods.The targeted proteins were purified by affinity chromatography.FL37(△ftsZ-Cat) strains were constructed via linear DNA homol-ogous recombination.Living cell imaging was performed to observe the cellular localization patterns of FtsZ protein and its mutants in E.coli strains.The interactions between FtsZ-FtsZ/FtsZ mutants were examined by coi-mmunoprecipitation assay . The polymerization properties of FtsZ mutants were analyzed by light scattering.The activities of GTPase were monitored by using high performance liquid chromatography.Re-sults The P74, G77 and A81 amino acids were respectively replaced by different polar amino acids to change the amphipathicity of the helix within the domain of FtsZ ( 74-82 ) .The YFP-labeled FtsZP74R , FtsZG77D and FtsZA81R mutants failed to assemble into functional Z-ring structure in E.coli strains.The inter-actions between FtsZ protein and its mutants were weakened or completely disappeared.In addition, in vitro experiments showed that P74R, G77D and A81R mutations caused a decrease in the polymerization efficien-cy of FtsZ monomer.The activity of GTPase was significantly decreased in the FtsZA81R mutant. Conclusion The P74, G77 and A81 were critical amino acids in the function and assembly of FtsZ protein in E.coli strains.Moreover, A81 amino acid regulated the lateral interaction of FtsZ monomer and the activity of GTPase.

AlM:To compare the effect of different incision in corneal astigmatism after phacoemulsification.
METHODS: Totally 88 cases ( 122 eyes ) with pure cataract were randomly divided into two groups. Forty cases (60 eyes) were clarity corneal incision in group A, and 48 cases ( 62 eyes ) were sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism ( SlA ) , uncorrected visual acuity ( UCVA ) and best correct vision acuity ( BCVA ) were observed in pre- and post-operation at 1d;1wk;1mo.
RESULTS: The mean astigmatism had statistically significant difference between two groups at 1d; 1wk;1mo after operation(P<0. 05). The SlA had statistically significant difference at 1d ( P<0. 05 ); The SlA had no statistically significant difference between two groups at 1mo after operation (P>0. 05). UCVA≥0. 5 and BCVA≥0. 8 had statistically significant difference at 1d; 1wk ( P<0. 05) . There had no statistically significant difference at 1mo after operation (P>0. 05).
CONCLUSlON: Phacoemulsification with scleral tunnel incision remove combined intraocular lens ( lOL ) implantation has small changes to corneal astigmatism. By selecting personalized corneal incision according to the corneal topography might be more beneficial.

The development of agency of Pregnancy technique shakes the traditional reproductive ethic and challenges the present law as it brings happiness of being parents to infertile couples.We should not only recognize its rationality,but also alert its potential harnfulness to society and ethic.Reasonably taking advantage of agency of Pregnancy technique and working out relative legislation are two important ways to prevent the corresponding legal and ethical confusion

Objective To evaluate the penumbra of a new multileaf collimator equipped with Elekta Synergy accelerator. Methods The penumbra were derived from beam profiles measured in air and water using PinPoint ion chamber with PTW MP3 water phantom. Variations of penumbra with X-ray beam energy, depth in water, and leaf position were investigated. Results The penumbra in air for 6 MV X-ray was 2 mm less than that at depth of maximal dose in water. The penumbra of leaf side was 1 mm less than that of the leaf end. The penumbra had close relationship with beam energy, depth in water and leaf position. Penumbra was increased with beam quality and water depth. The leaf position had great influence on the penumbra. Conclusions The penumbra of the multileaf collimator is related to its original design and radiation delivery technique. Special considerations should be taken into during treatment planning.Regular measurement should be performed to guarantee the delivery quality.

The hemolysin production of 19 strains of Streptococcus spp. isolated from pigs in the Jiangsu and Shanghai regions in recent years were examined. Eight isolates of Streptococcus suis type 2 from Jiangsu showed weak hemolysis on blood agar, but a stronger reaction in Todd-Hewitt broth(THB). The hemolysin belonged to the group of thiol-activated hemolysins. Nine strains of Streptoccus equi subsp. zooepidemicus showed strong hemolysis on blood agar and in THB containing 5% new-born calf serum, but no hemolysis in THB alone. This hemolysin was similar to streptolysin S(SLS). Another two isolates were atypical members of Lancefield group C Streptococcus and showed strong hemolysis on blood agar and in THB with 5% new-born calf serum, but the hemolysin was unlike either streptolysin O or SLS.
