ObjectiveTo analyze the epidemiological characteristics of a local dengue fever cluster outbreak in Qingpu District of Shanghai in 2024, and to provide a reference for subsequent dengue fever prevention and control. MethodsSeven confirmed local dengue fever cases reported through the National Notifiable Infectious Diseases Surveillance System in Qingpu District of Shanghai in 2024 were selected as the research subjects. Descriptive epidemiological methods were used to conduct investigation and analysis from the aspects of onset, medical treatment and reporting, clinical symptoms, travel and contact history within 15 days before onset, and activity trajectories. ResultsA total of 7 cases were identified in this outbreak. None of the cases had a travel history to dengue-endemic areas within 15 days prior to onset, while all had shared exposure environments and mosquito bite histories, indicating a local clustered transmission pattern. The main clinical manifestations included fever (100.00%) and myalgia (42.86%). All 7 cases were positive for dengue virus serotype 2 (DENV-2) by nucleic acid testing. Genetic sequencing showed that the virus strains belonged to the Cosmopolitan genotype and were most closely related to the epidemic DENV strains circulating in southern China in recent years. ConclusionThis outbreak might be a local secondary infection caused by the short-term stay of dengue fever-infected individuals, and the possible source of importation was dengue fever endemic areas in southern China.

Objective To translate English version of sensory-motor profile awake ( SMP-a) into Chinese version (the Chinese Version of SMP-a),and analyze the reliability and validity of the scale before and after craniotomy under awakening anesthesia. Methods Eighty-one patients whose tumors were located near or already in sensory-motor functional area were included in this study. Before and after awake cranioto-my,the Chinese version of SMP-a was used to accurately assess the sensory-motor function of each patient. Finally, the reliability and validity of the scale were analyzed by SPSS statistical software. Results Cronbach's α coefficient in the Chinese version of SMP-a was 0. 971,and Cronbach's α coefficient in the four subscales of face,hand,leg and sensation was 0. 965,0. 989,0. 981 and 0. 970,respectively. The test-retest reliability of the Chinese version of sensorimotor assessment scale was 0. 910,0. 904,0. 884,0. 898 and 0. 695 (total,face,hands,legs and sensory score respectively). The raters' consistency reliability was above 0. 949,0. 960,0. 934,0. 887 and 0. 660,respectively. The Pearson correlation coefficients of sensorimotor function score with SF-36 physiological function factors and KPS score were 0. 868 and 0. 790,respectively. Conclusion Before or after operation,the Chinese version of SMP-a has preferable reliability,internal con-sistency reliability and structural validity. It is feasible in awakening anesthesia craniotomy,and the degree of damage can be determined by repeated measurement of the sensorimotor sites that may be impaired by the patient.
