Objective To investigate the relationship between social support and state-trait anxiety in senior middle school students.MethodsA total of 165 senior middle school students received Social Support Questionnaire and State-Trait Anxiety Inventory,and social support and anxiety were compared by gender,home address and one-child family.Chi-square test and t test were used for data analysis.Results Utilization of social support showed significant difference between male and female studen(t=-1.994,P<0.05).Significant difference of objective support existed between grade one,grade two and grade three (F=0.935,P<0.05).Significant differences of social support(t=-2.039,P<0.05)and subjective support(t=-2.769,P<0.05)were found between urban and rural areas.In difierent grades,the state and trait anxiety Was significantly different(F=3.063,P<0.05=.There was negative correlation between social support and state-trait anxiety(r=-0.376,P<0.05=.ConclusionGood social support may help to reduce state anxiety among senior middle school students.
2.Pay attention to the long-term toxicities of therapy on lymphoma
Journal of Leukemia & Lymphoma 2010;19(11):641-645
There are an increasing number of survivors of successful treatment of lymphomas over the past 30 years. Although these survivors may be cured of their lymphoma, long-term morbidity and mortality are associated with late toxicities of the treatment. Identification of these late complications will lead to strategies to manage them when they occur and hopefully decrease the risk of their development. Secondary malignancies and treatment associated cardiovascular disease are the leading causes of late morbidity and mortality.Musculoskeletal difficulties, endocrine abnormalities, including sterility and thyroid disease, and heart and lung damage, have also been seen.The late complications of primary treatment of lymphoma and autologous stem cell transplantation usually for relapsed disease are the subjects of this paper.

Objective To explore the significance of detecting IgH gene rearrangement in diagnosis of non-Hodgkin lymphoma. Methods By using family-specific primers mixtures (VH1,VH2,VH3) for IgH FR3A,FR2A,FR1 genes,clonal IgH gene rearrangement was detected by heminested and multiplex PCR in 44 cases of B-NHL,1 undifferentiated lymphoma,15 T-NHL and 5 lymphonode reactive hyperplasia. Results Clonal IgH gene rearrangement was detected in 36 of 44 B-NHL (positive rate 82%) by using FR3A primers,27 of 44 B-NHL (positive rate 61%) by using FR2A primers. By using FR1 family-specific primers mixtures (VH1,VH2,VH3) and JH (JHb,JHc),clonal IgH gene rearrangement was demonstated respectively in 34/33 of 44 B-NHL (positive rate 77%,75%). The total positive rate was 95% (42/44) by combined family-specific primers mixtures (VH1,VH2,VH3) of FR3A,FR2A,FR1 gene. Four of 15 T-NHL revealed clonal IgH gene rearrangement,while 5 LRH had no clonal IgH gene rearrangement. One NHL unclassified by immunohistochemical methods was classified definitely as B cell-derived lymphoma by PCR. Conclusion The detection rate of IgH gene rearrangement can be improved by combined usage of several pairs of primers,especially family-specific primers. Detecting clonal IgH gene rearrangement is significant in the procedure of differential diagnosis for B/T-NHL and reactive hyperplasia.

Uracil (I) (2,4-Diketo-pyrimidine) was isolated from the radix aconiti collected from Jiangyou region of Sichuan Province.The chemical structure of this principle was determined by elemental analysis,IR,UV,MS,'H and 13C-NMR spectral data. The experiments were made to study the effect of uracil (I) on the cardiac contractile force and beating rate of the isolated toad hearts in comparison with uracil (II) (artificial synthesis). The results indicated that the 5?mol/L of uracil (I) and uracil (II) both had the effect of increasing the amplitude of myocardial contraction (P0.05) at 3 and 5 min. When the concentration was increased to 10 and 20?mol/L, the amplitudes of myocardial contraction were more incremental and 3 min later,the estimated value of uracil (I) and uracil (II) to increase the amplitude of myocardial contraction by 50% approached to 4.17 and 4.68, respectively. As described above, uracil (I) is a new cardiotonic in Jiangyou Fuzi.
