Objective To analyse the clinical characterization of intraductal papillary mucinous neoplasm of pancreas (IPMNs) and to improve the understanding of IPMNs.Methods Three hundred and sixty-one patients with IPMN at Shanghai Changhai Hospital between 1993 and 2012 were retrospectively analyzed.Results Among 361 cases of IPMNs,241 were men and 120 were female,with a female to male ratio of 2.6∶1.Mean age of the patients was 62 years old (16 ～ 87 years old).The duct type included the main duct in 102 patients (28.3％),a branch duct in 109 (30.2％),and mixed ducts in 150 (41.6％).The most common symptom at presentation is pancreatitis,which occur in 167 patients (46.3％).The sensitivity for the detection of IPMN was 80.2％ by ERCP,76.9％ by MRCP,63.9％ by CT,and 50.5％ by EUS.One hundred and twenty-nine patients (35.7％) were operated and diagnosed with 87 (67.2％) IPMA,21 (16.4％) IPMB,10(8.2％) IPMC(CIS) and 10 (8.2％) had invasive carcinomas.The 5-year survival rates of IPMA,IPMB,IPMC,and invasive carcinomas were 100％,100％,66.5％,and 44.7％,respectively.Conclusions IPMNs were fregrently occured is 60 years old,half of patients had acute pancreatitis history and the frequtly attack,mixed type is most anatomy type,and the outcome after surgery is good.

Early warning of infectious disease outbreak is key to controlling epidemics. Public general hospitals can effectively play their " outpost" role in the early warning and response of infectious diseases, which is directly related to the success of epidemic prevention and control. The authors summarized the current construction and main functions of infectious disease early warning systems at national level, regional level and public general hospitals, analyzed the problems existing in such construction, and put forward targeted suggestions. As found by the authors, some public general hospitals in China have initially built an early warning system for infectious diseases, achieving early recognition, early warning and reporting of infectious diseases to some extent. However, these systems were challenged by such shortcomings as insufficient intelligence, lack of data information exchange, immature practice and application, and lack of attention to the monitoring and early warning of endemic infectious diseases. It is suggested to improve the policy and system support in the future, to expand the types of infectious diseases for monitoring and early warning, to enlarge the sources of monitoring data and to strength hospital informationization construction.

[摘 要] 目的：评估放疗作为原位疫苗的联合治疗模式在晚期软组织肉瘤（STS）患者中的有效性和安全性。方法：回顾性分析2020年12月至2024年9月期间在南京大学医学院附属鼓楼医院肿瘤中心接受联合治疗模式的12例晚期STS患者的临床资料。12例患者均接受了联合治疗。放疗主要以大分割为主。靶向治疗：安罗替尼10例、阿帕替尼2例。免疫治疗以PD-1抗体为主。主要研究终点为疾病控制率（DCR），次要研究终点为客观有效率（ORR）及安全性。结果：接受联合治疗的12例STS患者中有0例CR，4例PR，7例SD，1例PD。ORR为33%，DCR为91.7%，其中靶病灶的DCR为100%。12例患者中，9例出现Ⅰ~Ⅱ级不良反应。最常发生的血液学不良反应是贫血（6例）、肝功能检查结果异常（3例）。最常发生的非血液学不良反应是尿蛋白（5例）、高血压（4例）、甲状腺功能异常（3例）、厌食（3例）、恶心呕吐（2例）；仅2例发生Ⅲ级血液毒性，有1例发生Ⅲ级气胸。结论：放疗作为原位疫苗的联合治疗模式在晚期STS患者中展现出较高的DCR，且未出现严重不良反应。该联合治疗模式具有良好的有效性与安全性。
