Objective: To explore the relationship between the cognitive style of field dependence-independence and self-supporting levels in primary school students.Methods: One hundred and twenty grade 4 to 6 primary school students were examined by the Self-supporting Behavior Questionnaire for 6 to 12 Years Old Children,and then the subjects were divided into two groups,of which the high-self-supporting group includes the top 27% according to the questionnaire total score,and the low-self-supporting group includes the bottom 27%.Both the groups were tested by the Embedded Figures Test.Results: ①The high self-supporting group get significantly higher score in the Embedded Figures Test than the low self-supporting group;and the field-independence group get significantly higher scores in the scholastic self-supporting and self-determination subscales of the Self-supporting Behavior Questionnaire than the field-dependence group;②the score of Embedded Figures Test was significantly correlated with the scores of scholastic self-supporting,self-supporting in daily life,self-determination,self-action,responsibility undertaking,and the total score of the Self-supporting Behavior Questionnaire.Conclusion: Children's self-supporting levels were related to their cognitive style,namely,the high self-supporting children were inclined to field-independence cognitive style,and vice versa.

Objective:To explore the relationship between Parental Rearing Behavior and self-supporting levels in pri-mary school students.Methods:①79 grade 5 to 6 primary school students were examined by the Self-supporting Behav-ior Questionnaire for 6 to 12 Years Old Children and EMBU scale;②And then the subjects were divided into two groups,of which the high-self-supporting group includes the top 27% according to the questionnaire total score,and the low-self-supporting group includes the bottom 27%.Results:①Compared with the low self-supporting group,the high self-supporting group get significantly higher score of the emotional warmth and understanding of father and mother;compared with the high self-supporting group,the low self-supporting group get significantly higher score of refusal of mother,rejec-tion and punishment of father and mother;②Self-supporting of children was negatively correlated with refusal of mother,rejection and punishment of father and mother;positively with emotional warmth and understanding of father and mother.Conclusion:Children's self-supporting levels were related to parental style.

Objective:To explore the relationship between self-supporting levels and mental locus of control(internalexternal locus of control)in primary school students.Methods:193 grade 5 to 6 primary school students were examined by the Self-supporting Behavior Questionnaire for 6 to 12 Years Old Children and Multidimentional Measure of Children’s Perception of Control(MMCPC);and then the subjects were divided into two groups,of which the high-self-supporting group includes the top 27%according to the self-supporting behavior questionnaire total score,and the low-self- supporting group includes the bottom 27%.Results:①The high self-supporting group get significantly lower score in unknown control and powerful others’control subscales than the low self-supporting group,and get significantly higher score in internal locus of control than the low self-supporting group;②Except social self-supporting,the other dimentions in Self-supporting Behavior Questionnaire were negatively correlated with unknown control and powerful others’control; were positively correlated with the internal control.Conclusion:Children’s self-supporting level were closely related to mental locus of control.the high self-supporting children were inclined to the internal control,and vice versa.

Objective: To explore the relationship between self-supporting levels and the early parent-child attachment in primary school students. Methods: 193 grade 5 to 6 primary school students were examined by the Self-supporting Behavior Questionnaire for 6 to 12 Years Old Children and Adult Attachment Questionnaire (AAQ 3.1); and then the subjects were divided into two groups, of which the high-self-supporting group included the top 27% according to the self-supporting behavior questionnaire total score, and the low-self-supporting group included the bottom 27%. Results: ①The low-self-supporting group got significantly higher score in mother negative loving, father negative loving, mother rejecting, father rejecting, mother anger and father anger subscales than the highself-supporting group; ②The children’s self-supporting behaviors were negatively correlated with mother negative loving, father negative loving, mother rejecting, father rejecting, mother anger and father anger. Conclusion: Children’s self-supporting levels were closely related to the early parent-child attachment. The refusal, rejection, negative loving, and anger of parents might play a passive role in the development of children’s self-supporting behavior.

Objective:To explore the relationship between the self-supporting levels and self-concept in primary school students.Methods:193 grade 5 to 6 primary school students were examined by the Self-supporting Behavior Questionnaire for 6 to 12 Years Old Children and Tennessee Self-concept Scale,and then the subjects were divided into two groups,of which the high-self-supporting group includes the top 27% according to the questionnaire total score,and the low-self-supporting group includes the bottom 27%.Results:①The high self-supporting group get significantly higher score in all subscales of Tennessee Self-concept Scale than the low self-supporting group;②All subscales of Tennessee Self-concept Scale were significantly positively correlated with all dimentions of Self-supporting Behavior Questionnaire.Conclusion:Children's self-supporting behaviors were closely related to self-concept.The higher level of self-supporting,the more positive their self-concept.

Expression of major histocompatibility complex class 1(MHC-1)and thyroid specific transcription factor-1(TTF-1)in thyroid follicular epithelia of Graves'disease and Hashimoto's thyroiditis measured by immunohistochemistry technique were all significantly increased as compared with those in normal controls,suggesting that TTF-1 and MHC-1 seem to contribute to the development of autoimmune thyroid diseases.

Objective To investigate the expression of hepatocyte growth factor receptor (HGFR) in epiretinal membranes (ERM) of eyes with proliferative vitreoretinopathy (PVR) and cultured retinal pigent epithelium (RPE) cells. Methods Fifteen human epiretinal membranes were obtained from eyes undergone vitrectomy for rhegmatogenous retinal detachment complicated with PVR and observed by immunohistochemical examination to study the expression of HGFR. Using the immunohistochemical technique to evaluate the expression of HGFR in cultured RPE cells. Results In 6 membranes of PVR grade C, HGFR were expressed in 5/6, and 7 cases were detected in 9 membranes of PVR grade D.RPE cells express readily detectable levels of HGFR. Conclusion The findings indicate that HGF might be involved in the formation of epiretinal membranes in PVR.

With the development of organ transplantation for nearly half a century, currently the hot issues in clinical renal transplantation have already shifted to the application of low toxicity immunosuppressive drugs and their projects, as well as the research of technique which induces low or no immunity response to the specific donor. At present the main effective strategies of inducing immune tolerance are donor specific blood transfusion and donor specific bone marrow transplantation. This article summarizes the background, mechanism and clinical application of these two strategies.

Objective To investigate the effect of HGF on proliferation and migration in cultured human RPE cells. Methods Human RPE cells cultured in serum-free medium were treated with HGF(1,2,10,50,100 ?g/L), and MTT assay was used to detect the growth of the cells; an in vitro wound healing model was used to count the number of cells that had entered the denudate area in RPE migration treated with HGF (1,2,10,50,100 ?g/L) after 20 h. Results HGF(10,50,100 ?g/L) increased proliferation rates of cultured human RPE (18 2 % to 34 8 %), and at a concentration of 50 ?g/L on day 3 HGF induced the maximal increase of proliferation( P

Objective:To validate whether there is self-schema of self-supporting and to look into the difference in amount of recall,amount of recognition and reaction time between children with high score of self-sporting and those with low score.Methods:Levels of self-supporting of 300 sixth grade students from a primary school in Hunan were assessed by using a Self-supporting Behavior Questionnaire for Six to Twelve Years'Old Children,and the subjects were grouped into two groups,of which the high-score group includes the top 35 from the questionnaire result,and the low-group includes the lowest 35.Then the SRET task was assigned to the two groups and a contrastive study of their self-schema was carried out.Results:The amount of recognition of self-supporting words by the two groups is larger than that of non-self-supporting words;The reaction time of the self-supporting group is longer than that of the other group;there is no significant difference in the amount of correct recognition.Conclusion:High self-supporting group showed self schema of self-supporting,and low self-supporting group showed not only self schema of non-self-supporting but also that of self-supporting,which implies that self-supporting is not a dichotomy concept of self.
