Tumor 2008;28(1):57-60
Objective: To investigate the frequency of microsatellite instability (MSI) and loss of heterozygosity (LOH) in thymoma and its relationship with clinicopathological parameters. Methods: We selected 5 microsatellite polymorphism markers and extracted DNA from 28 specimens of paired thymomas/normal tissues. MSI and LOH in the specimens of thymomas and relevant pericancerous tissues were detected by polymerase chain reaction (PCR) followed by 6% polyacrylamide gel electrophoresis (PAGE) with silver staining. SP immunohistochemical method was used to assess the expressions of epithelial growth factor receptor (EGFR), p53, Bcl-2, and Ki-67 proteins in thymoma. Results: MSI or LOH was detected in 11 out of 28 thymoma tissues. The frequency of MSI was 21.4% (6/28), 10.7% (3/28), 14.3% (4/28), 10.7% (3/ 28), and 0% (0/28) at loci of D6S1708, TP53, DM, D11S988, and D8S136. LOH at D6S1708 (5/6) was a common genetic alteration. DM had only MSI alteration and D11S988 had only LOH alteration. There was no significant association between MSI and LOH with age, sex, with or without myasthenia gravis (MG), histological classification, clinical staging, and immunohistochemical staining (EGFR, p53, Bcl-2, and Ki-67 proteins) (P > 0.05). Conclusion: D6S1708, TP53, DM, and D11S988 are sensitive loci for studying microsatellite DNA imbalance in thymoma. Microsatellite DNA imbalance may play a certain role in occurrence and develoyment of thymoma, and the relationship between MSI or LOH and clinicopathological features of thymoma needs further investigation.

Objective To observe the effect of the Chinese medicine on the patients’ thyroid autoantibodies TPOAb and TGAb of Hashimoto's thyroiditis. Methods 100 cases of Hashimoto's thyroiditis were randomly divided into group A and group B, with 50 cases in each group. Group A was given levothyroxine sodium(L-T4) to maintain thyroid function(FT3,FT4,TSH)in the normal range, at the same time Chinese medicines of soothing liver and strengthening spleen, nourishing the liver and kidney, activating blood and removing blood stasis were additionally added;while group B was taken L-T4 to maintain the thyroid function in the normal range. The levels of TPOAb, TGAb were determined before and after treatment in both groups. Results After the treatment, the level of TGAb and TPOAb[respectively(106.3±29.5)IU/ml,(871.5± 209.3)IU/ml] in group A were decreased compared with their previous level [respectively(385.5±76.6)IU/ml, (1621.5±399.2)IU/ml], the difference was statistically significant(t were 48.2、10.6,P<0.01). The level of TGAb and TPOAb [respectively(437.6±135.4)IU/ml,(1798.6±434.6)IU/ml] in group B were slightly increase than their previous level[respectively(383.9±105.8)IU/ml,(1633.2±396.5)IU/ml], with no significant difference. The levels of TPOAb and TGAb in group A had significant difference than those in group B after the treatment(t were 22.3、19.6,P<0.01). Conclusion TCM combined with L-T4 can reduce the level of thyroid autoantibodies of TPOAb and TGAb-in patients.
