Objective:To present an evaluation indicator system for access to cancer screening services.Methods:The evaluation indicator pool was constructed through a scoping review. The theoretical framework was constructed based on the multi-source indicators, and the qualitative expert consultation method was employed to form the initial version of the three-level evaluation indicator system. Delphi expert consultation method was conducted in two rounds to evaluate the relevance, importance, and availability of the proposed evaluation indicator system. The expert positive coefficient, authority coefficient, coordination degree of expert opinions, and concentration of expert opinions were subjected to analysis. Subsequently, the three-level evaluation indicator system for access to cancer screening services was adjusted and determined based on the boundary value method and the open opinions of experts. Finally, the combination weight method was employed to determine the weight.Results:The initial version of the indicator system comprised 3 primary (first-level) indicators, 11 secondary (second-level) indicators, and 46 tertiary (third-level) indicators. Delphi expert consultation was conducted for the initial version, and 17 experts ultimately completed it, exhibiting a positive coefficient of 100% and an authority coefficient of 0.87. In comparison to the initial round of consultation, Kendall's W coefficient ranges (0.15-0.43, all P<0.05) of relevance, importance, and availability scores for each tertiary indicator in the second round exhibited an improvement. The analysis of the importance dimension indicates that expert opinions are also more concentrated, as evidenced by an increase of 8.5% and 7.0% in the proportion of the tertiary indicators with an arithmetic mean above 8 and a full mark ratio above 0.5, respectively. The final evaluation indicator system comprises three primary indicators, with the weights of structure evaluation, process evaluation, and outcome evaluation being 0.338, 0.378, and 0.285, respectively. It also comprises 11 secondary indicators and 45 tertiary indicators. Conclusions:The evaluation indicator system developed in this article can be an effective evaluation tool for quantitative comparison of access to cancer screening services across different populations, cancer types, and before and after intervention. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Objective To analyze the identification of pathogenic bacteria in municipal sewage of Hangzhou City, Zhejiang Province from January to October 2023, to understand the serotype and drug resistance of Vibrio cholerae isolated from sewage, as well as to predict the virulence gene and drug resistance gene carrying situation. Methods From January to October 2023, urban sewage samples from various environments in Hangzhou City, Zhejiang Province, were continuously collected for bacterial isolation and culture. The serotypes of 27 Vibrio cholerae strains were identified by slide agglutination method, and the drug sensitivity test was conducted by micro broth dilution method. Whole genome sequence and bioinformatics software were used to predict drug resistance genes and virulence genes. Results The sewage identification results showed 26 bacteria genera, including Salmonella, Vibrio, Enterobacter, and Aeromonas, among 82 bacterial species. All 27 strains of Vibrio cholerae were non-O1 and non-O139 serogroups. The strains showed high resistance rates to ampicillin, ampicillin/sulbactam and cotrimoxazole at 59.26%, 14.81%, and 14.81%, respectively), exhibited high sensitivity to cefotaxime, tetracycline, chloramphenicol, meropenem, ertapenem, ceftazidime, ceftazidime/avibactam, amikacin, ciprofloxacin, tigecycline, and azithromycin. A total of 21 different drug resistance genes were detected in 11 strains of Vibrio cholerae, among which the highest carriage rate of β-lactam resistance genes reached 63.64%, and 1 strain carried 17 kinds of drug resistance genes. None of the 11 strains of Vibrio cholerae carried ctxA, ctxB, ace, zot, or chxA genes, but all the strains carried rtxB, rtxC, and rtxD genes; 90.91% of the strains carried hlyA, and 36.36% carried rtxA. Conclusions All Vibrio cholerae isolated from sewage in this study are non-O1 and non-O139 serogroups, showing good sensitivity to most antibiotics, but also they carry a certain number of drug-resistance genes and virulence genes. This suggests that future monitoring efforts should focus on these strains, providing certain data support for the study of the characteristics of Vibrio cholerae isolated from sewage.

Objective:To investigate the correlation of the expressions of programmed death ligand 1 (PD-L1) and interleukin-10 (IL-10) with the prognosis in uterine cervical cancer tissues.Methods:A total of 82 patients with uterine cervical cancer hospitalized at Nantong Maternal and Child Health Hospital from January 2015 to December 2019 were retrospectively analyzed, and the clinicopathological data of all patients were collected and sorted out. Immunohistochemical method was used to detect the positive expression of PD-L1 protein in cancer tissues, and Western blot was used to detect the expression level of IL-10 protein in cancer tissues. The survival of all patients for 24-month follow-up was recorded and 82 patients were divided into the survival group and the death group. The clinicopathological characteristics and the expressions of PD-L1 and IL-10 in both groups were compared. Multivariate Cox proportional risk model was used to analyze the factors affecting the survival of patients with uterine cervical cancer. The value of PD-L1 and IL-10 expressions predicting the survival in uterine cervical cancer was evaluated by using receiver operating characteristic (ROC) curve. The best cut-off value of IL-10 relative expression in cancer tissues obtained from ROC curve analysis predicting 24-month survival of patients was used to group; ≥ the best cut-off value was treated as IL-10 high expression group, and < the best cut-off value was treated as IL-10 low expression group. Kaplan-Meier method was used to compare the survival of PD-L1 positive and negative groups, IL-10 high and low expression groups.Results:There was no loss of follow-up in 82 patients during 24-month follow-up, of which 11 cases (13.4%) died and 71 cases (86.6%) survived. The proportion of patients with Federation International of Gynecology and Obstetrics (FIGO) staging Ⅲ-Ⅳ, poor differentiation, tumor long diameter > 4 cm and lymph node metastasis in the death group was higher than that of those in the survival group (all P < 0.05). PD-L1 was positive in 9 of 11 patients in the death group and 11 of 71 patients in the survival group ( P < 0.001). The relative expression level of IL-10 protein in the death group was higher than that in the survival group (1.18±0.32 vs. 0.89±0.21, P < 0.001). Multivariate Cox regression analysis showed that FIGO staging, tissue differentiation degree, tumor long diameter, whether lymph node had metastasis or not, whether PD-L1 was positive and the relative expression level of IL-10 protein were independent factors affecting patients' 24-month survival (all P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of PD-L1 and IL-10 single and the combination of both predicting 24-month survival in cancer tissues was 0.748 (95% CI 0.664-0.894), 0.710 (95% CI 0.655-0.884) and 0.839 (95% CI 0.742-0.951), respectively. There were 20 cases in PD-L1-positive group and 62 cases in PD-L1-negative group. The best cut-off value of relative expression level of IL-10 protein was 7.12. There were 19 cases in IL-10 high expression group and 63 cases in IL-10 low expression group. The overall survival of patients in PD-L1-positive group was worse than that in PD-L1-negative group (24-month overall survival rate: 55.0% vs. 96.8%, P = 0.001). The overall survival of patients in IL-10 high expression group was worse than that in IL-10 low expression group (24-month overall survival rate: 57.9% vs. 95.2%, P = 0.001). Conclusions:The prognosis of patients with positive PD-L1 and IL-10 high expressions in uterine cervical cancer tissues is poor. The combined detection of PD-L1 and IL-10 has a high predictive effect on the prognosis.
