Chinese Journal of Endocrinology and Metabolism 2000;0(06):-
Objective To observe the changes in the pathological diagnosis rate of Graves'disease(GD) and Hashimoto's thyroiditis(HT)in the past 28 years and to probe its relationship to the environmental factors. Methods Statistic analysis was performed on data of thyroid disease,GD,HT and the complications of HT in Department of Pathology(1978-2005)in General Hospital of Tianjin Medical University with Run test,Cox-stuart test,ANOVA,t or t'test and Chi-square test.Results In 28 years there were 243 403 biopsies(average 8 693/ year)including 6 771 cases of thyroid disease(27.8‰),216 cases of GD(0.89‰),352 cases of HT (1.45‰).The biopsy rate of thyroid disease and GD showed a descending tendency since 1982 but an ascending tendency from 1995,furthermore,with GD it showed a descending tendency from 2001 to 2005 once more.While the biopsy rate of HT and GD+HT showed a descending tendency from 1986 and an ascending tendency after 1996,being 1-4 years later than thyroid disease and GD.The biopsy rate of GD+HT and the proportion of HT showed a descending tendency in 2002-2005 and 2003-2005 respecitvely.The average age of total and female patients with GD showed a descending tendency from 1997.The average age of GD was 13.7 years younger than HT,the patients of GDⅠ-type andⅡ-type being younger thanⅢ-type.The average age of lymphoid type(L), oxyphilie epithelium type(O),pronounced epithelium destruction type(P)in HT increased sequentially.In 28 years,there were more female patients with GD and HT,especially with HT.There existed 7.95% hyperthyroidism,6.25% nodular goiter,2.27% carcinoma in HT(more in L-type)and 2.56% hypothyroidism in HT(more in P-type).Conclusion Within 28 years,according to the pathological diagnosis rate,GD,HT,and GD+HT showed phasic tendencies related to drinking low iodine water and the implement of universal salt iodization policies in 1994 and 2000.Therefore,on the levels of genetics and environment,the factors that influence autoimmunity of thyroid gland could not exclude the variations of iodine intake,infection,affection or emotional stress.The mechanism of the changes in the pathological diagnosis rate needs further study.

Objective To investigate the relationship between IGF2BP3 hypomethylation with colon tumor differentia?tion. Methods Tissue samples from 41 colorectal cancer were collected from March 2011 to August 2011 in our hospital, among which 19 cases were well-differentiated adenocarcinoma, 12 cases were of moderately differentiated adenocarcinoma and 10 cases were of poorly differentiated adenocarcinoma. Meanwhile biopsy samples from 12 cases of colonic colitis were collected as a control. The expression of IGF2BP3 was assessed by immunohistochemistry and Western blot. An innovate of ELISA technique was used to examine global methylation levels while IGF2BP3 methylation level was tested by methylation specific PCR technique. Results The expressions of IGFBP3 are higher in all colon cancer groups than that in colitis (P<0.05). The expression of IGFBP3 in poorly differentiated adenocarcinoma is higher than that in all the other groups, but there is no significant difference between its expressions in the well differentiated group and in the moderately differentiated adeno?carcinoma group. The global DNA level and IGFBP3 methylation level of every colon cancer group is lower than those in coli?tis (P<0.05). Also, a tendency of decreasing global DNA and IGFBP3 methylation status was observed comparing well differ?entiated towards poorly differentiated carcinomas (P<0.05). Conclusion IGF2BP3 expression in colorectal cancer is asso?ciated with differentiation of colon cancer tissue. A lower global and IGF2BP3 DNA methylation suggest a worse differentia?tion of colon cancer. DNA hypomethylation may therefore play a regulatory role in the expression of IGF2BP3 in colon cancer tissue.

OBJECTIVETo investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention.
METHODSA total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed.
RESULTSThe effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318).
CONCLUSIONA high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.
