Objective:To investigate the protein expression of human epidermal growth factor receptor 2 (c-erbB2), CyclinD1, and protein kinase B1 (Akt1) in papillary thyroid carcinoma tissue.Methods:A retrospective study was conducted to collect papillary thyroid carcinoma tissues, adjacent tissues, pathological and medical records, as well as one year follow-up data of patients ( n = 117) diagnosed with papillary thyroid carcinoma at Huai'an Cancer Hospital in Jiangsu Province from January 2021 to October 2022. The protein expression of c-erbB2, CyclinD1, and Akt1 were determined by immunohistochemistry. The positive rates of c-erbB2, CyclinD1, and Akt1 proteins in cancerous tissue and adjacent tissues, and cancerous tissue of patients with different clinical features and recurrence status were compared. Results:There were statistically significant differences in the positive rates of c-erbB2 [36.75% (43/117) vs 5.98% (7/117)], CyclinD1 [47.86% (56/117) vs 6.84% (8/117)], and Akt1 proteins [64.96% (76/117) vs 11.97% (14/117)] between the cancerous tissue and adjacent tissue of patients with papillary thyroid carcinoma (χ 2 = 32.96, 49.55, 69.41, P < 0.001). There were statistically significant differences in the positive rates of c-erbB2, CyclinD1, and Akt1 proteins in cancerous tissues of patients with different tumor node metastasis (TNM) classification staging, invasion of the capsule, and lymph node metastasis (χ 2 = 40.67, 20.47, 12.07, 13.68, 7.25, 9.16, 22.04, 27.18, 46.31, P < 0.05). There was no statistically significant difference in the positive rates of c-erbB2, CyclinD1, and Akt1 proteins in cancerous tissues of patients with different genders, ages, smoking history, drinking history, maximum tumor diameter, and whether the tumor was multifocal or accompanied by Hashimoto's thyroiditis ( P > 0.05). The follow-up results of 117 patients with papillary thyroid carcinoma showed that there were 15 cases of recurrence and 102 cases of no recurrence. The positive rates of c-erbB2, CyclinD1, and Akt1 proteins in the cancerous tissue of the recurrence group were higher than those of the non recurrence group (χ 2 = 4.00, 4.47, 6.09, P < 0.05). Conclusion:The positive rates of c-erbB2, CyclinD1, and Akt1 proteins in papillary thyroid carcinoma tissues are relatively high, and are closely related to TNM classification staging, invasion of the capsule, lymph node metastasis, and recurrence.

Objective To discuss the CT manifestations of renal leiomyosarcoma. Methods 9 cases of renal leiomyosarcoma proved by pathology were analyzed retrospectively. Results CT imaging showed homogeneous hyperattenuation in two cases. Heterogeneous in density with necrosis inside was observed on the CT scan in six cases. After contrast medium administration heterogeneous enhancement with cystic and necrotic areas could be revealed in all cases on both CT scan. Conclusion Large renal mass with intra-tumor necrosis,cystic and hemorrhagic change is the characteristic manifestations of renal leiomyosarcoma. But differential diagnosis from renal carcinoma by CT clinical setting is difficult before surgery, and final diagnosis should depend on pathology examination.
