Objective By analyzing the epidemiological characteristics and trends of brucellosis in Ji'nan City,to provide a scientific basis for further prevention and control of the disease.Methods Serum samples of suspected brucellosis patients were collected from every county (city,district) of Ji'nan City from 2008 to 2014,and these samples were screened by Rose-bengal plate agglutination test (RBPT).Then positive samples were confirmed by Standard tube agglutination test (SAT),and experimental data and results were analyzed by statistics.Results Totally 2713 serum samples of suspected brucellosis patients were tested,and 200 were positive by SAT.Temporal distribution:the serum antibody positive specimens were detected each month throughout the year,and the results showed clear seasonal prevalence by concentrating from March to September (82.07％,151/184).Population distribution:the serum antibody positive rate of males was higher than that of females,the ratio was 2.08:1.00,and the cases were found among 15 to 75 years old,while concentrated from 30 to 65 (67.00％,134/200).Spatial distribution:except Huaiyin District,positive samples were detected in all other 10 counties (cities,districts) of Ji'nan City,most of them (92.5％,185/200) in Shanghe,Zhangqiu,Changqing,Shizhong and Licheng counties (cities,districts).Conclusions Brucellosis epidemic in Ji'nan is serious,and cases have occurred mostly in spring,summer and autumn.It is recommended that health propaganda and education should be strengthened in order to enhance selfprotection awareness of the exposed population,and then improve the physical examination for early discovery,early reporting and early treatment.At the same time,it is important to cooperate with the Department of Livestock to prevent and control brucellosis.

Objective:To carry out the scoping review on the form, function and application effect of decision aids for breast reconstruction of breast cancer patients, so as to provide reference for domestic research on decision aids for breast reconstruction.Methods:According to the scoping review framework, literature was systematically searched on Web of Science, PubMed, Cochrane Library, Embase, Scopus, CINAHL, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The retrieval period was from the establishment of the database to January 19, 2024.Results:A total of 14 articles were included, including 8 randomized controlled trials (RCT), four quasi-experimental studies, one qualitative study, and one prospective cohort study. The main forms of decision aids included web-based software programs, mobile applications (APP), decision support groups, or decision support manuals. The evaluation of intervention effectiveness mainly involved indicators such as patient decision regret, decision conflict, satisfaction, acceptance, and patient-reported outcomes.Conclusions:Breast reconstruction decision aids have a certain positive impact on improving patient satisfaction, decision quality, and patient-reported outcomes, but most studies have not examined their long-term effects. The research on decision aids for breast reconstruction in China is still in its infancy. It is suggested that future research should draw on relevant foreign studies to develop and advance high quality and diversified decision aids, and promote their clinical applications.
