Objective@#To investigate the trend in mortality of malignant tumors in Xiaoshan District, Hangzhou City from 2017 to 2022, so as to provide insights into formulation of the malignant tumor control strategy.@*Methods@#Data on mortality of malignant tumors in Xiaoshan District from 2017 to 2022 were collected through Hangzhou Municipal Chronic Disease Monitoring Management System, and the cause of death composition ratio and crude mortality were calculated. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010. The trend in mortality of malignant tumors were evaluated with average annual percent change (AAPC).@*Results@#There were 13 301 malignant tumor deaths reported in Xiaoshan District from 2017 to 2022, accounting for 31.26% of the total cause of death and ranking the first among the causes of death. The crude mortality was 186.36/105 and standardized mortality was 106.63/105. There was no significant trend in the crude mortality of malignant tumors in Xiaoshan District from 2017 to 2022 (P>0.05), while the standardized mortality showed a tendency towards a decline (AAPC=-1.409%, P<0.05). The crude and standardized mortality of malignant tumors were higher in men than in women (241.40/105 vs. 133.37/105; 132.66/105 vs. 79.35/105; both P<0.05). There was no obvious trend in the crude mortality of malignant tumors in men (P>0.05), and the standardized mortality showed a tendency towards a decline (AAPC=-3.017%, P<0.05). While there was no obvious trend in the crude and standardized mortality of malignant tumors in women (P>0.05). The crude mortality of malignant tumors showed a tendency towards a decline among residents at ages of 15 to 44 years and 65 years and older (AAPC=-3.933% and -2.413%, both P<0.05). The crude mortality of malignant tumors was higher in men than in women among residents at ages of 0 to 14 years, 45 to 64 years and 65 years and older (all P<0.05). The five most common causes of death included lung cancer, colorectal cancer, liver cancer, gastric cancer and pancreatic cancer, accounting for 66.96% of all malignant tumors. The crude mortality of colorectal cancer from 2017 to 2022 showed a tendency towards a rise (AAPC=2.815%, P<0.05).@*Conclusions@#The standardized mortality of malignant tumors showed a tendency towards a decline in Xiaoshan District from 2017 to 2022. Management of malignant tumors should be given a high priority among men at ages of 45 years and older, and lung cancer, colorectal cancer, liver cancer, gastric cancer and pancreatic cancer were leading causes of death.

RÉSUMÉ
Objective@#To investigats the specific changes of brain neuron oscillation in non-clinical high-trait anxiety college students by recording the resting state EEG of high and low trait anxiety subjects.@*Methods@#College students in a university were administered by using the S-TA Inventory, 27% of the number of people before and after the selection were divided into low-specific focus group (15) and high-trait anxiety group(15), based on the STAT score. After pre-processing, the data was divided into five frequency bands of δ(1-<4), θ(4-<8), α(8-<13), β(13-<30), γ(30-100)Hz and every electrode power value of those was calculated respectively. Correlation between power spectrum and trait anxiety scores was investigated.@*Results@#The high-trait anxiety group were in the frontal and central regions (t=3.47, 2.62) of the δ band, the frontal region (t=2.22) of the θ band, the frontal, central, right temporal, and posterior regions (t=2.77, 2.23, 3.65, 2.35) of the β band, the frontal, left temporal, central, right temporal, and posterior regions (t=2.83, 2.22, 2.64, 2.43, 2.09) of the γ band, than that in the low trait anxiety group. Furthermore, in central regions of the δ band; the frontal region of the θ band; the frontal, the central, and posterior regions of the β band; the frontal, left temporal, central, and posterior regions(r=-0.63, -0.51, -0.62, -0.53, -0.54, -0.59, -0.56, -0.55, -0.49) of the γ band, the correlation between trait anxiety scores and the power value were obvious negatively.@*Conclusion@#High trait anxiety college students have lower power spectrum than low trait anxiety college students. The degree of trait anxiety is related to the power spectrum. The changes of brain resting-state electrical signals in high-trait anxiety individuals may be related to the influence of trait anxiety on college students’ attention and working memory.
RÉSUMÉ
Objective@#To understand the relationships between college students’ aggression and self-acceptance, family intimacy and adaptability, and to provide reference for college students’ aggression preventing and intervening.@*Methods@#Using general information questionnaire, Aggression Questionnaire, Self-acceptance Questionnaire and FACES II-CV, 984 college students from 3 colleges in Xinxiang, Henan province were surveyed by questionnaire.@*Results@#The total score of physical aggression, verbal aggression, indirect aggression and aggression in male students was higher than that of female students (t=7.17,4.21,2.05,3.63,P<0.05).The score of physical aggression of only children was higher than that of nononly children (t=2.39,P<0.05).The score of indirect attack of disciplined college students was higher than that of undisciplined college students (t=2.60,P<0.01).There were statistically significant differences in the total scores of indirect attack, hostility and attack among college students with different left-behind experiences (F=3.39,4.61, 3.37, P<0.01).There were statistically significant differences in the total scores of physical aggression, anger and aggression among college students by family income(F=5.70,3.94,3.37,P<0.01).Correlation analysis showed that the total score of college students’ aggression was positively correlated with self-acceptance, negatively correlated with actual family intimacy and actual family adaptability (r=0.37，-0.09，-0.07,P<0.01). Regression analysis showed that self-acceptance, gender, disciplinary action, left-behind experience and expected family adaptability showed significant associations with total score of college students’ aggression (P<0.05).@*Conclusion@#Self-acceptance and family closeness and adaptability are associated with aggressive behavior in college students. Schools should carry out targeted psychological health education on self-acceptance to ensure that college students maintain a reasonable level of self-acceptance, and family members should develop certain level of intimacy and adaptability, in order to reduce the occurrence of aggressive behavior of college students.
