This study investigated the association between a proximal promoter polymorphism of IFNGR1 (interferon-γ receptor α chain, IFNGR-α) and breast cancer susceptibility, as well as the prognostic value of its expression variation in breast cancer patients. A case-control study was conducted at the Sixth Medical Center of PLA General Hospital from June 2020 to June 2022. The study included 182 pathologically confirmed breast cancer patients as the breast cancer group, 177 non-tumor patients with benign breast lesions as the benign breast lesions group, and 229 healthy individuals as the normal control group. 2-3 ml EDTA anticoagulant whole blood samples were collected from all participants, and genomic DNA was extracted and stored for further analysis. Basic patient information was retrieved from the hospital′s electronic medical records by patients′ ID number. The proximal promoter sequence of IFNGR1 was obtained from NCBI, and sequencing primers were designed using Primer Premier 6.0. Sanger sequencing was employed to analyze the IFNGR1 promoter sequence in the three groups, and the results were compared with the Eukaryotic Promoter Database (EPD) sequence using Bioedit software. Statistical analysis was performed on single nucleotide polymorphisms (SNPs) in the IFNGR1 promoter. The TCGA database was utilized to assess the relationship between IFNGR1 expression levels and breast cancer patient survival. The findings revealed that the -56 TG genotype of the IFNGR1 promoter was significantly associated with increased breast cancer risk ( Z=2.73, P<0.05). Notably, IFNGR1 expression was lower in breast cancer group compared to normal control group ( P<0.05). Analysis of the TCGA database indicated that patients with high IFNGR1 expression had longer survival times than those with low expression ( HR=0.87, 95% CI:0.77-0.98, P<0.05). In summary, the IFNGR1 -56 TG genotype is associated with an increased risk of breast cancer, and there is a positive correlation between IFNGR1 expression levels and the survival of breast cancer patients.

OBJECTIVE To explore the expression level of miR-196a in cervical cells infected with high-risk human papillomavirus(HPV)16 and 18.METHODS The Gene Expression Omnibus(GEO)was used to screen for dif-ferentially expressed miRNAs between HPV 16 or 18-positive cervical cancer cells and normal cervical cells.On-line biological software https://kmplot.com/analysis/was utilized to analyze the relationship between the most differentially expressed miRNA and the overall survival of cervical cancer patients.Cervical swab samples positive for HPV 16 or HPV 18,detected by real-time fluorescent quantitative polymerase chain reaction(qPCR)genoty-ping,were collected as the study subjects.Cervical swab samples from the same period of physical examination population that were negative for HPV 16 or HPV 18 by qPCR genotyping served as negative controls.The qRT-PCR method was employed to detect the level of miR-196a in cervical cells,with data processed via the 2-△△Ctmethod.RESULTS Differential analysis of the GSE86100 data revealed that miR-196a expression de-creased in HPV 16 or HPV 18-positive cervical cells(log2FC=-6.60,P＜0.001),while miR-3188 expression significantly increased(log2FC=6.22,P＜0.001).Using online analysis tools https://kmplot.com/analysis,it was found that cervical cancer patients with high miR-196a expression had a shorter overall survival compared to those with low m iR-196a expression(HR=1.87,95％CI:1.17-3.00,P=0.008).H owever,there was no cor-relation between miR-3188 and the overall survival of cervical cancer patients(HR=1.47,95％CI:0.92-2.37,P=0.110).The results of specific qRT-PCR testing showed that the expression levels of miR-196a in cervical cells positive for HPV 16 and HPV 18 were 0.93±0.09 and 0.51±0.07,respectively,which were lower than those in the normal control group(1.89±0.13)(P＜0.05),consistent with the sequencing analysis results CONCLUSIONS Infection of cervical cells with HPV 16 or HPV 18 can lead to decreased expression of miR-196a,and the expres-sion level of miR-196a is negatively correlated with the overall survival of cervical cancer patients.

ObjectiveTo investigate the current situation of rehabilitation therapists' work, and analyze the factors related to their career development and transformation. MethodsFrom September, 2022 to January, 2023, 153 rehabilitation therapists in Weifang were investigated with a cross-sectional questionnaire, using general questionnaire, Job Satisfaction Scale for Grassroots Health Technicians, Social Responsibility Scale, Job Role and Identity Inventory, and Employee Turnover Scale. ResultsThe majority of rehabilitation therapists interviewed were male (52.28%), under 35 years old (88.24%), with a bachelor's degree (77.78%), income less than 5 000 yuan a month (46.40%), and less than five years of service (48.36%). The work time was (7.78±0.84) hours a day, (5.39±0.51) days a week. The favorable rate of the physical environment of work was 67.32%, and the favorable rate of the interpersonal relationship environment of work was 80.39%. The score of professional identity was (3.61±0.84), the score of job satisfaction was (3.62±0.97), the score of social responsibility was (3.53±0.79), and the score of turnover was (2.39±1.10). Education level, job satisfaction, and social responsibility were the main factors related to the employee turnover (P < 0.05). ConclusionThe overall educational level of rehabilitation therapists is relatively low, and the human resource structure needs to be optimized. There is a significant difference between academic education and continuing education, and career development needs to be improved. The main factors related to career development and transformation are education level, job satisfaction, and social responsibility.

Objective: To construct an evaluation index system of public health emergency preparedness capacity in county-level centers for disease control and prevention (CDC), so as to provide the evidence for improving the public health emergency preparedness capacity in county-level CDC. Methods: An index system framework was created based on review of health emergency policies, laws and regulations released in China from 2003 to 2023. The importance, sensitivity and accessibility of indicators were scored and screened through two rounds of Delphi expert consultations, and the weights of indicators were calculated using precedence charts. The efficiency of Delphi expert consultations was evaluated using the active coefficient, authority coefficient and coordination coefficient. Results: Eighteen experts participated in consultations, including 9 men, 15 with educational levels of master degree and higher, 12 with preventive medicine or public health as the specialty, and 12 with deputy senior professional titles and higher. The active coefficients of two rounds of consultations were 100.00% and 94.44%, and the authority coefficients were 0.83 and 0.84, respectively. The coordination coefficients of secondary and tertiary indicators during the second round consultation were 0.341 and 0.241, which were both higher than those during the first round (both P<0.05). The final evaluation index system included 8 primary indicators, 21 secondary indicators and 58 tertiary indicators. Among primary indicators, health emergency organization and management (0.203 1), health emergency team building (0.203 1) and financial support for health emergency (0.203 1) had the highest weights, and of secondary indicators, completion degree of health emergency administration regulations (initial weight/global weight: 0.750 0/0.152 3), health emergency team building (0.750 0/0.152 3) and financial support for emergency (0.750 0/0.152 3) had the highest weights, while among tertiary indicators, defining the duty of health emergency administration sectors had the highest weight (0.750 0/0.114 2). Conclusion The created evaluation index system is feasible for evaluation of the public health emergency preparedness capacity in county-level CDC.

Objective To explore the application and method of World Health Organization Rehabilitation Competency Framework (RCF) in rehabilitation human resource management, and provide theoretical and practical reference for rehabilitation human resource management.Methods Based on the International Standard Classification of Occupations issued by the International Labour Organization, the application scope of RCF was systematically analyzed. The theoretical framework of rehabilitation human resource management based on RCF was constructed in combination with competency-based human resource management framework. On this basis, taking rehabilitation nurses as an example, the corresponding management methods and paths are proposed from four aspects of human resource management, including career management, recruitment and selection, training and development, and performance appraisal and salary management.Results Based on RCF, the theoretical framework of human resource management for rehabilitation nursing positions was constructed, and the main contents and processes of human resource management based on RCF were clarified from four aspects: recruitment and selection, training and development, performance appraisal and salary management, and career management. Occupational competency of rehabilitation professionals in International Standard Classification of Occupations was analyzed by RCF.Conclusion The rehabilitation competency framework constructed by WHO can be used to supplement the responsibilities of rehabilitation-related professionals in the International Standard Classification of Occupations issued by the International Labour Organization. RCF serves as a tool for practice managers and rehabilitation professionals in identifying selection criteria, learning objectives, and professional title assessment criteria. It can also be used in recruitment and selection, training and development, performance appraisal, salary management and career management in the field of rehabilitation human resource management.

Objective To explore the theory and method of performance evaluation for rehabilitation workers based on the World Health Organization Rehabilitation Competency Framework (RCF).Methods Using the theoretical framework and methods of the RCF, we analyzed rehabilitation workers' related competencies from the five dimensions, namely practice, professionalism, learning and development, management and leadership, and research, integrating core values and beliefs, competencies and behaviors, activities and tasks, and knowledge and skills, to construct a comprehensive evaluation method and pathway for rehabilitation workers' performance.Results Based on the RCF, which confirms the job competency requirements for rehabilitation workers, a multi-dimensional, multi-level and standardized performance evaluation index framework was formed. For example, performance evaluation system of physical therapists was consisted of five primary indicators and 26 secondary indicators from the combination of RCF and job standards.Conclusion The rehabilitation worker performance evaluation based on the RCF can evaluate the performance of rehabilitation workers in a scientific, standardized and comprehensive way.
