Purpose To detect the expressions of stress induced phosphoprotein 1 (STIP1) and estrogen receptor-α(ER-α) in papil-lary thyroid carcinoma and to analyse the relationship between STIP1 and ER-α. Methods 54 cases of paraffin-embedded tissues of papillary thyroid carcinoma, 18 cases of papillary thyroid carcinoma with lymph node metastasis, 15 cases of Hashimoto’ s thyroiditis, 10 cases of adjacent normal thyroid tissue were collected. The expressions of STIP1 and ER-αwere detected by immunohistochemistry, and the relationship between the expressions and clinicopathological features of papillary thyroid carcinoma was analyzed. Results The expression of STIP1 and ER-α in papillary thyroid cancer group ( 55. 6% and 44. 4%) were higher than that of normal thyroid group (10% and 0) and Hashimoto’s thyroiditis group (8. 3% and 0, all P<0. 05). STIP1 expressions was related to lymph node metastasis ( P<0. 05 ) , while ER-α expression was related to gender, TG-Ab and the merger of nodular goiter, but not related to lymph node metastasis (P>0. 05). The expressions of STIP1 and ER-α in papillary thyroid carcinoma were not related to patients’ age , tumor location, number of tumors, tumer size, invasion of capsule, the concomitant Hashimoto’ s thyroiditis and TPO-Ab ( all P>0. 05). And the expressions of STIP1 was not related to gender, TG-Ab and the merger of nodular goiter (all P>0. 05). A positive correlation was found between the expressions of STIP1 and ER-αin thyroid papillary carcinoma (P<0. 05). Conclusion STIP1 and ER-α in papillary thyroid carcinoma may be related with lymph node metastasis.

Objective To analyze the correlation between CT characteristics and epidermal growth factor receptor (EGFR)mutations in pulmonary adenocarcinoma.Methods 82 patients (87 lesions)with pulmonary adenocarcinoma were retrospectively collected.All patients were underwent CT examination before operation,and EGFR gene were determined after operation.Results EGFR mutations were found in 44 of 87 lesions (50.57%).The EGFR mutations rate was 50.00% in females and 47.50% in males,there was no statistical difference between genders (P=0.821).The EGFR mutations rate was 46.55% in the right lung and 58.62% in the left lung,while no statistically significant difference was found (P=0.289).Among all the CT characteristics,the mutations rate was 63.89% in spiculated lesions and 60.71% in lesions with pleural indentation,the differences was statistically significant (P<0.05).The mutations rate was 59.25% in lesions containing solid component and 36.36% in pure ground glass opacity lesions,the difference was statistically significant (P=0.011). There were no statistically differences in lobulation,cavitation and lymphadenectasis (P>0.05).The pleural indentation was the highest in sensitivity (77.27%)and negative predictive value (67.74%).The spiculation was the highest in specificity (69.77%)and positive predictive value (63.89%).Conclusion Among all the CT characteristics,pleural indentation,spiculation and the lesion containing solid component are prone to EGFR mutations.

Objective:To improve the understanding of cervical papillary squamous cell carcinoma (PSCC), and to provide evidence for the diagnosis and treatment of PSCC.Methods:The clinicopathological and follow-up data of 18 patients diagnosed PSCC by preoperative cervical biopsy in Tangshan Gongren hospital were collected, the correlation of preoperative biopsy, liquid-based cells, and human papilloma virus (HPV) with postoperative pathology and prognosis was analyzed.Results:The concordance rate between preoperative biopsy and postoperative pathology was 50% (9/18). 4 patients showed the characteristic features of PSCC in their liquid-based cells of the 9 patients who were diagnosed as PSCC postoperatively (4/9), the HPV infection rate was 44.4% (4/9), the International Federation of Gynecology and Obstetrics stage were IA1-IB1, no lymph node metastasis, recurrence or death occurred in all patients.Conclusions:Cervical biopsy before operation has certain limitations in the diagnosis of PSCC, which requires a clear diagnosis by postoperative pathology. The HPV infection rate is lower, the stage is earlier and the prognosis is better in PSCC. Some patients can choose a less invasive surgical method than radical surgery.

OBJECTIVES: Gram-positive cocci is the main pathogen responsible for early infection after liver transplantation (LT), posing a huge threat to the prognosis of liver transplant recipients. This study aims to analyze the distribution and drug resistance of Gram-positive cocci, the risk factors for infections and efficacy of antibiotics within 2 months after LT, and to guide the prevention and treatment of these infections. METHODS: In this study, data of pathogenic bacteria distribution, drug resistance and therapeutic efficacy were collected from 39 Gram-positive cocci infections among 256 patients who received liver transplantation from donation after citizens' death in the Third Xiangya Hospital of Central South University from January 2019 to July 2022, and risk factors for Gram-positive cocci infection were analyzed. RESULTS: Enterococcus faecium was the dominant pathogenic bacteria (33/51, 64.7%), followed by Enterococcus faecalis (11/51, 21.6%). The most common sites of infection were abdominal cavity/biliary tract (13/256, 5.1%) and urinary tract (10/256, 3.9%). Fifty (98%) of the 51 Gram-positive cocci infections occurred within 1 month after LT. The most sensitive drugs to Gram-positive cocci were teicoplanin, tigecycline, linezolid and vancomycin. Vancomycin was not used in all patients, considering its nephrotoxicity. Vancomycin was not administered to all patients in view of its nephrotoxicity.There was no significant difference between the efficacy of daptomycin and teicoplanin in the prevention of cocci infection (P>0.05). Univariate analysis indicated that preoperative Model for End-Stage Liver Disease (MELD) score >25 (P=0.005), intraoperative red blood cell infusion ≥12 U (P=0.013) and exposure to more than 2 intravenous antibiotics post-LT (P=0.003) were related to Gram-positive cocci infections. Multivariate logistic regression analysis revealed that preoperative MELD score >25 (OR=2.378, 95% CI 1.124 to 5.032, P=0.024) and intraoperative red blood cell transfusion ≥ 12 U (OR=2.757, 95% CI 1.227 to 6.195, P=0.014) were independent risk factors for Gram-positive cocci infections after LT. Postoperative Gram-positive cocci infections were reduced in LT recipients exposing to more than two intravenous antibiotics post-LT (OR=0.269, 95% CI 0.121 to 0.598, P=0.001). CONCLUSIONS Gram-positive cocci infections occurring early after liver transplantation were dominated by Enterococcus faecalis infections at the abdominal/biliary tract and urinary tract. Teicoplanin, tigecycline and linezolid were anti-cocci sensitive drugs. Daptomycin and teicoplanin were equally effective in preventing cocci infections due to Gram-positive cocci. Patients with high preoperative MELD score and massive intraoperative red blood cell transfusion were more likely to suffer Gram-positive cocci infection after surgery. Postoperative Gram-positive cocci infections were reduced in recipients exposing to more than two intravenous antibiotics post-LT.
