Objective To investigate the value of human papilloma virus(HPV)DNA,HPV E6/E7 protein and thin-prep cytology test(TCT)in cervical intraepithelial neoplasia(CIN)and cervical cancer screening.Methods A total of 190 adult women who received early cervical cancer screening in Department of Gynecology,Zhuji People's Hospital from July 2021 to June 2022 were selected as the study objects.HPV DNA,HPV E6/E7 protein and TCT were detected,respectively,and further colposcopic biopsy was performed.The diagnostic efficacy of HPV DNA,HPV E6/E7 protein and TCT in patients with different lesions were compared.Results The positive rates of HPV DNA,HPV E6/E7 protein,TCT and combined detection in CIN3 and cervical cancer patients were significantly higher than those in cervicitis patients(P<0.05).The positive rates of HPV DNA,HPV E6/E7 protein,TCT and combined detection in cervical cancer patients were significantly higher than those in CIN1 patients(P<0.05).The positive rates of HPV DNA,HPV E6/E7 protein,TCT and combined detection in CIN2+ patients were significantly higher than those in CIN1-patients.The sensitivity,specificity,positive predictive value and negative predictive value of HPV DNA,HPV E6/E7 protein and TCT in the diagnosis of high-grade lesions were 90.80%,30.10%,52.32%and 79.48%,respectively.Conclusion HPV DNA,HPV E6/E7 protein and TCT can be used as screening methods for cervical cancer and precancerous lesions,with the combination of the three being the most sensitive.

Objective:To explore the feasibility, accuracy and reproducibility of a novel, fully automated three-dimensional echocardiography right ventricular(RV) quantification software(3D Anto RV) to evaluate the RV volume and RV ejection fraction (RVEF) using artificial intelligence in patients after heart transplantation (HT) comparing with the gold reference-cardiac magnetic resonance (CMR).Methods:Forty-six patients after HT who were scheduled for echocardiogram at their routine follow-up examinations and also agreed to undergo CMR examination within the following 24 hours in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from October 2018 to June 2019 were prospectively included. The right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV) and RVEF of HT patients were measured by CMR 3D Auto RV and conventional semi-automated three-dimensional echocardiography RV quantification software (Tomtec 4D RV function 2.0). The results of the 3D Auto RV and conventional semi-automated Tomtec were respectively compared with CMR using paired two-tailed student′s t-tests, Pearson correlation coefficients and Bland-Altman analyses. Results:The feasibility of the 3D Auto RV was 87%.The fully automated analysis realized in 27 (59%) patients by 3D Auto RV and the analysis time required only (12±1)s. The results of the remaining 19 (41%) patients needed manual adjustment and the mean analysis time in manual adjustment was also <2 min that was shorter than the conventional semi-automated three-dimensional echocardiography RV quantification software[(108±15)s vs (160±34)s, P<0.001]. For the results of RV volumes: There were good correlations between the 3D Auto RV and CMR, conventional semi-automated Tomtec and CMR for the measurements of RVEDV, RVESV and RVSV ( r=0.77-0.84, all P<0.001). In addition, compared with CMR, although there were significantly underestimated RV volumes by the 3D Auto RV and conventional semi-automated Tomtec, the negative bias was smaller in the 3D Auto RV than the conventional semi-automated Tomtec. For the results of RVEF: the corresponding RVEF derived from 3D Auto RV and CMR showed an excellent correlation and consistency ( r=0.84, P<0.001; bias=-1.1%, Limit of agreement=-8.1%-6.0%). In addition, the correlations between the manual adjustment by 3D Auto RV and the CMR ( r=0.63-0.72, all P<0.001) was lower than the correlations between the 3D Auto RV and the CMR ( r=0.76-0.82, all P<0.001) for RV volumes and RVEF.Finally, 3D Auto RV had a good reproducibility. Conclusions:The new fully 3D Auto RV quantification software underestimate RV volumes that less than the conventional semi-automated Tomtec. And the 3D Auto RV quantification software can accurately evaluate the RVEF in patients after HT with rapid analysis and higher reproducibility, which may also support the routine adoption of this method during follow-ups of HT patients in the daily clinical workflow.

Objective: To summarize the clinical experience of cardiopulmonary bypass(CPB) in acute type A aortic dissection received aortic arch reconstruction on age over 70 years patients. Methods: From April 2013 to December 2017, 35 elderly patients aged over 70 who were involved the aortic arch, brachiocephalic trunk, left common carotid artery and left subclavian artery and severe arch lesions, large false lumen and large rupture risk of acute A aortic dissection were reconstructed by triple-branched stent graft in emergency extracorporeal circulation. During the period of cardiopulmonary bypass, selective cerebral perfusion and discontinuous arrest under moderate hypothermia(25 degrees C) were used to reduce the time of cerebral ischemia and hypoxia, and to strengthen the management of the protection of important organs. Results: Cardiopulmonary bypass time was(144.85±32.98)minutes, and aortic cross clap time was(51.82±17.59)minutes, and selective cerebral perfusion time was(12.17±4.70)minutes, discontinuous arrest time was(4.50±3.54) minutes, the lower body arrest time was(16.6±7.49)minutes. All patients were smoothly weaned from cardiopulmonary bypass.35 patients resuscitated within 48 hours, of which 3 patients had transient mental disorders in the early stage and recovered before hospital discharge; 2 patients had cerebral infarction. Hospital mortality in this group was 17.1%(6/35). Conclusion Advanced age is not a contraindication to the reconstruction of the arch of the aortic dissection. Reasonable management of cardiopulmonary bypass can provide an important guarantee for the reconstruction of the elderly patients with acute type A aortic dissection.
