ABSTRACT
Objective@#To investigate the trends in incidence of malignant tumors in Xiaoshan District, Hangzhou City from 2015 to 2020, so as to provide the evidence for improving the control strategy for malignant tumors. @*Methods@#Data on incidence of malignant tumors in Xiaoshan District from 2015 to 2020 were collected through Hangzhou Municipal Chronic Disease Monitoring Management System. The crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were calculated, and the trends in incidence of malignant tumors were analyzed using average annual percent change (AAPC). @*Results@#The crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were 476.95/105, 333.30/105, 257.01/105, 28.30% and 425.79/105 in Xiaoshan District from 2015 to 2020, which all appeared a tendency towards a rise (AAPC=4.36%, 3.82%, 3.99%, 3.79% and 5.20%, all P<0.05). The crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were 491.47/105, 313.31/105, 251.51/105, 28.78% and 338.82/105 among men, and both the crude incidence and truncated age-standardized incidence for 35 to 64 years appeared a tendency towards a rise (AAPC=3.00% and 1.73%, both P<0.05), while the crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were 462.98/105, 348.46/105, 262.13/105, 27.74% and 504.91/105 among women, which all appeared a tendency towards a rise (AAPC=5.77%, 5.72%, 5.79%, 5.65% and 7.48%, all P<0.05). The incidence of malignant tumors appeared a tendency towards a rise with age, and the crude incidence of malignant tumors showed a tendency towards a rise among people at ages of 15 to 44 years and 45 to 64 years (AAPC=9.85% and 4.88%, both P<0.05). Lung cancer, thyroid cancer, colorectal cancer, breast cancer and gastric cancer were the five most common cancers, accounting for 59.63% of all malignant tumors, and the incidence of lung cancer, thyroid cancer, colorectal cancer and breast cancer all showed a tendency towards a rise (AAPC=5.90%, 13.01%, 4.60% and 4.47%, all P<0.05). @*Conclusions @#The incidence of malignant tumors showed a tendency towards a rise in Xiaoshan District from 2015 to 2020. The rise in the incidence of malignant tumor was higher in females than in males, and malignant tumors tended to develop at a young age. Lung cancer, thyroid cancer, colorectal cancer, breast cancer and gastric cancer are major malignancies that threaten human health in Xiaoshan District.
ABSTRACT
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.
ABSTRACT
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.
