Objective To evaluate the effectiveness of thermal tomography in breast cancer (BC) screening. Methods We conducted a general population-based BC screening in three regions of Hubei Province (Xiantao, Hongan, and Yangxin Districts). Participants underwent a questionnaire-based interview for baseline data collection. They then received a physical examination, thermal tomography, and ultrasound from doctors and technicians. We compared the efficacies, including sensitivity, specificity, and false-positive rates, of ultrasound and thermal tomography in BC screening. Results A total of 59 712 eligible women were included in this screening program. The BI-RADS 1, 2, 3, 4, and 5 accordance rates between the two screening methods were 0.9549, 0.8047, 0.9037, 0.3352, and 0, respectively. The overall accordance rate was 0.933 1. The kappa consistency results showed that the Cicchetti-Allison and Fleiss-Cohen kappa values were 0.7970 and 0.8583, respectively. Although the two methods had equal sensitivities, specificity was higher in thermal tomography than in ultrasound. The false-positive rate was lower in thermal tomography than in ultrasound. The area under the receiver operating characteristic (ROC) curve of thermal tomography was significantly larger than that of ultrasound. Conclusion The general consistency between thermal tomography and ultrasound in BC screening was high. Thermal tomography outperformed ultrasound in terms of specificity and diagnostic efficiency. Therefore, thermal tomography has a high application value for general population-based BC screening.

Objective To evaluate the efficacy of human papillomavirus E6/E7(HPV E6/E7)mRNA combined with colposcopy in screening cervical cancer and precancerous lesions.Methods A total of 480 patients with suspected cervical precancerous lesions in the hospital from July 2022 to De-cember 2024 were retrospectively selected as research objects.All the patients underwent HPV E6/E7 mRNA testing,colposcopy,and pathological examination.Taking the pathological examination results as the diagnostic golden standard,the diagnostic values of HPV E6/E7 mRNA and colposcopy alone as well as their combination were analyzed.Results The pathological examination results of 480 pa-tients showed that there were 192 negative cases,including 1 case of normal cervix and 191 cases of benign lesions;there were 288 positive cases,including 133 cases of low-grade squamous intraepithe-lial lesions(LSIL),110 cases of high-grade squamousintraepithelial lesions(HSIL),and 45 cases of cervical squamous cell carcinoma(SCC).The colposcopy results showed 211 true-positive cases and 138 true-negative cases;the HPV E6/E7 mRNA test results showed 199 true-positive cases and 137 true-negative cases;the combined test results showed 239 true-positive cases and 174 true-negative cases.The sensitivity(95.22％),specificity(75.98％),accuracy(86.04％),positive predic-tive value(81.29％),and negative predictive value(93.55％)of the combined test were signifi-cantly higher than those of each individual test(P＜0.001).Moreover,the consistency between the combined test and pathological results(Kappa=0.718,P＜0.001)was also significantly high-er than that of each individual test.Conclusion Compared with HPV E6/E7 mRNA or colposcopy alone,the combined test has higher clinical application value in screening of cervical precancerous lesions and cervical cancer,shows stronger consistency with pathological results,and is of great sig-nificance for the early differential diagnosis of cervical precancerous lesions and cervical cancer.

Objective To explore the targets and mechanisms of Tongguanteng Injection in inhibiting the proliferation and migration of cervical cancer.Methods The biological activity of Tongguanteng Injection in inhibiting human cervical cancer SiHa cells was determined by MTT method.Detecting the effect of Tongguanteng Injection on SiHa cell migration through wound healing assay.Using network pharmacology to collect the key targets for treating cervical cancer,and perform molecular docking and enrichment analysis on the targets.Immunohistochemistry and Western blot were used to detect the key proteins to validate the network pharmacology predictions.Result Tongguanteng Injection significantly inhibited the proliferation and migration in a dose-dependent manner in human cervical cancer SiHa cells.Based on the main active ingredients of Marsdenia tenacissima,81 therapeutic targets for cervical cancer were obtained,which may treat cervical cancer by affecting key proteins such as FGF2,MAPK1,and MAPK3.Immunohistochemical results indicated that FGF2,MAPK1 and MAPK3 were expressed in cervical cancer tissues.The western bolt assays showed that Tongguanteng Injection could significantly reduce the FGF2 protein expression.Meanwhile,the MAPK1 and MAPK3 protein expressions were significantly increased.Conclusion Tongguanteng Injection may regulate the FGF2,MAPK1 and MAPK3,effectively impede the proliferation and migration of cervical cancer.

To explore the application of sequential analysis in post-market safety dynamic surveillance of vaccines. Under the dynamic monitoring data of vaccines post-market approval, this research introduces the fundamental principles of maximizing sequential probability ratio test (MaxSPRT) and Bayesian sequential analysis, employing R software. Through an example of dynamic safety monitoring data of vaccines post-market approval, we analyze using the MaxSPRT and Bayesian sequential analysis. The MaxSPRT identified a safety signal in week 4 ( P<0.05), while Bayesian sequential analysis indicated that the 95% highest density interval for the RR value at week 4 is 1.13-3.27, suggesting the first appearance of a safety signal at week 4. The MaxSPRT and Bayesian sequential analysis effectively leverage continuously accumulating dynamic monitoring data, thereby serving as a valuable method for post-market safety surveillance of vaccines.

Objective To investigate the association between body roundness index(BRI)and hyperuricemia(HUA)in patients with type 2 diabetes mellitus(T2DM).Methods 555 T2DM inpatients were selected from July 2022 to October 2023 in Gansu Province People's Hospital Endocrinology.According to BRI,the T2DM patients were divided into four group:low BRI(L-BRI,BRI≤3.579,n=140)group,moderate BRI(M-BRI,3.579

AIM:To evaluate the application effec-tiveness of a Bayesian mixture model based on the principal stratum strategy for estimating the com-plier average causal effect(CACE)in clinical trials with non-compliance.METHODS:Using a non-infe-riority randomized controlled trial investigating a novel drug for primary type 2 diabetes mellitus(non-inferiority margin:-0.4)as a case study,the primary analysis applied a Bayesian mixture model under the monotonicity assumption to estimate CACE of between-group differences in glycated he-moglobin(HbA1c)changes within the compliant stratum,followed by non-inferiority testing.Sensi-tivity analyses included a Bayesian mixture model relaxing the monotonicity assumption and compar-ing results with per-protocol set(PPS)analysis.RE-SULTS:In the primary analysis,the posterior mean of CACE for HbA1c change in the compliant stratum was 0.081％,with a one-sided 97.5％credible inter-val lower bound of-0.124,exceeding the non-infe-riority margin(-0.4％),supporting the non-inferiori-ty efficacy of the novel drug in the compliant stra-tum(P(H1|Data)=1).Consistent findings were ob-served in PPS analyses(estimated effect:0.136％;one-sided 97.5％credible interval lower bound:-0.069％),further validating methodological robust-ness.CONCLUSION:In clinical trials with noncom-pliance as an intercurrent event,the Bayesian mix-ture model under the principal stratum strategy ef-fectively adjusts for compliance-related bias and yields conservative,robust estimates of causal ef-fects,supporting its value in efficacy evaluation un-der complex compliance scenarios.
