Objective:To discusses the variations of 7Be, 137Cs and 210Pb activity concentrations in the air in Beijing from March 16, 2021 to March 31, 2023, and their correlation with temperature, precipitation, relative humidity, barometric pressure, PM10 (only limited to 137Cs) and other meteorological parameters. Methods:A total of 60 aerosol samples were collected using the HRHA01-SFS1000/A ultra-large flowair sampler in the automatic radiation monitoring station. The activity concentrations of 7Be, 137Cs and 210Pb in the aerosol samples were measured by GMX-60 low background anti-Compton high purity germanium gamma spectrometer. Pearson correlation coefficient was used to show the correlation of the relevant parameters. Results:The seasonal mean values of 7Be activity concentration were spring 4.31 mBq/m 3, summer 3.53 mBq/m 3, autumn 3.09 mBq/m 3 and winter 2.45 mBq/m 3, respectively, ranging from 1.17 to 7.79 mBq/m 3, with the overall mean of (3.36±1.33) mBq/m 3. The activity concentration of 137Cs ranged from 0.39 to 8.49 μBq/m 3, with an average of (0.59±1.47) μBq/m 3. The average activity concentrations of 210Pb were spring 0.53 mBq/m 3, summer 0.44 mBq/m 3, autumn 0.72 mBq/m 3 and winter 0.75 mBq/m 3, respectively, ranging from 0.21 to 1.36 mBq/m 3, with an average of (0.56±0.26) mBq/m 3. The activity concentration of 7Be was correlated with temperature and pressure ( r=0.38, -0.40), the activity concentration of 137Cs was correlated with precipitation ( r=-0.41), and the activity concentration of 210Pb was correlated with temperature and pressure ( r=-0.31, 0.37). The variation of 137Cs activity concentration in the air showed an obvious seasonal pattern, and the peak value generally appears in spring of each year (March to May), which was related to the frequent spring dust in Beijing. The activity concentration of 210Pb in the air was affected by coal combustion heating in winter, and has a peak value during November to March. Conclusions:The activity concentrations of 7Be, 137Cs and 210Pb in the air in Beijing are within the normal range, showing a seasonal trend.

Objective: To explore the characteristics of psychological control of parents of college students and their correlation with health risk behaviors, and to provide a reference for further improving parenting styles and improving the physical and mental health of college students. Methods: With the method of multi-stage stratified random sampling, 3 318 college students from 6 universities in Guizhou Province were selected. The parents’ psychological control questionnaire and Chinese adolescent health-related behavior questionnaire were used to conduct anonymous field survey. Results: A total of 660 students’ parents have got low score of mental control in low-score group (<26), 1 844 in the middle group (26-49) and 814 in the high group (>49). Students who had suicide plans scored higher in the dimensions of invasion of privacy, inhibition of speech expression, and sense of disability than those who had not(t=4.08, 3.74, 3.82, P<0.01); The scores of smokers in achievement expectation, invasion of privacy and ability ineffectiveness were higher than those of non-smokers(t=7.12, 3.91, 8.10, P<0.01); the scores of drinkers in all dimensions were higher than those of non drinkers(t=9.35, 4.64, 5.90, 8.78, P<0.01); the scores of Internet addicts in all dimensions were higher than those of non-smokers(t=8.92, 14.27, 3.70, 15.94, P<0.01). Spearman correlation analysis showed that smoking, drinking and Internet addiction were positively correlated with parents’ psychological control(r=0.11, 0.15, 0.19, P<0.01). Conclusion Parents’ psychological control of college students in achievement expectation, ability ineffectiveness and speech inhibition; parents’ psychological control is positively related to smoking, drinking and Internet addiction behavior. Parents should give more active encouragement and guidance to their children and strengthen communication.

Objective: To understand the smoking of college students in Guizhou Province and to explore associated factors for better prevention and control of smoking behavior. Methods: A multi-stage stratified random sampling method was used to describe the current smoking situation of college students. And 2 451 college students of different majors and grades from three cities with high, medium and low economic development levels were selected. Besides, we used multivariate logistic regression analysis to analyze the major factors affecting current smoking. Results: Ever smoking rate of college students in Guizhou Province was 50.8%, the peak age of first smoking attempt was 8-13(35.2%); current smoking rate of college students in Guizhou Province was 20.8%. Logistic regression analysis showed that male, upper grade, monthly living expenses of not less than 1 000 yuan, single parents, family smoking and peer smoking were the main risk factors affecting college students’ smoking(OR=5.52,1.44,1.48,1.69,1.47,1.88,P<0.05). Conclusion College students in Guizhou Province have a higher rate of smoking attempt and low rate of current smoking, as well as low tobacco dependence which is determined by multiple factors. Tobacco hazard education, mental health education and living environment intervention for college students may help reduce the probabitity for tobacco use.

Parkinson′s disease (PD) is the second most common neurodegenerative disease in middle-aged and elderly people. In addition to motor symptoms, PD also has many non motor symptoms, such as dysosmia, constipation, cognitive impairment, etc. Among them, dysosmia is a common non motor symptom of early Parkinson′s disease. Research has confirmed that olfactory dysfunction (OD) can appear before the typical clinical symptoms of PD, which is of great significance to the diagnosis and treatment of diseases. However, at present, the pathogenesis of OD is still unclear, and the inspection methods have not been unified, and there is no complete cure. This article reviews the latest research progress of dysosmia in Parkinson′s disease.
