RESUMO
Objective:To explore and analyze the correlation between thyroid peroxidase (TPO) and thyroglobulin (Tg) in patients with papillary thyroid carcinoma (papillary thyroid carcinoma, PTC) and to provide a more reasonable plan for the clinical diagnosis and treatment of patients.Methods:A retrospective analysis was made of 142 PTC patients who underwent surgical resection from Jun. 2019 to Jun. 2022 in the Oncology Department of Wenzhou Hospital of Traditional Chinese Medicine. 115 patients were selected, including 25 males (21.74%), and 90 females (78.26%), and the average age was (43.48±9.74) years old. The medical records, pathology reports, and demographic characteristics and pathological characteristics were collected. Immunohistochemical staining was used to detect the expression of TPO and Tg in PTC tissues, which were divided into positive and negative groups. Multifactorial Logistic regression analysis was used to analyze its relationship with clinicopathological characteristics and prognosis of patients.Results:The negative rate of TPO was 95.45% (105 cases). Univariate analysis showed that the tumor diameter ( t=5.746), lymph node metastasis, and the proportion of PT1 patients were significantly different between the two groups ( P<0.05), the TPO negative group was significantly higher than the positive group. Multivariate logistic regression analysis found that tumor diameter, lymph node metastasis, and proportion of PT1 patients were independent factors (95% CI=2.367-5.365, 1.101-2.738, 1.103-2.589, P<0.05). The positive rate of Tg was 77.41% (89 cases). Univariate analysis showed the proportion of people with BMI ≥ 25 ( χ2=11.180), tumor diameter ( t=2.117), and intracapsular invasion ( χ2=8.354), extrathyroidal invasion, lymph node metastasis ( χ2=27.740), and proportion of PT1 patients were significantly different between the two groups ( P<0.05). Multivariate logistic regression analysis found BMI≥25, intracapsular invasion, extrathyroidal invasion, lymph node metastasis, proportion of PT1 patients were independent factors affecting Tg in patients with PTC (95% CI=3.845-11.735, 1.485-2.983,1.171-2.762,4.083-16.526,1.003-2.174, P<0.05). There was a negative correlation between the expression of TPO and Tg in PTC ( r=-0.498, P<0.001) . Conclusion:TPO and Tg are highly correlated with tumor lymphatic metastasis, pathological grade, tumor diameter and tumor invasion range in patients with papillary thyroid carcinoma, and the expression of the two is negatively correlated, which can be used as effective indicators for evaluating the prognosis of patients.
RESUMO
50%).The resistance of Enterococcus avium and E.faecalis to ciprofloxacin was over 30%.CONCLUSIONS To Gram-negaive bacteria may use ?-lactamase inhibitors with antimicrobials and amikacin.To nonfermenters may use ciprofloxacin.To Gram-positive bacteria may use teicoplanin,nitrofurantoin,ampicillin/sulbactam and others.
