Objective To explore the symptom prevalence in the patients with pulmonary nodules in Lingnan area and to investigate the influencing factors,thus to provide data support for the construction of differentiation and treatment system of symptoms-syndrome elements-syndromes-constitutions for patients with pulmonary nodules,and to promote the establishment of secondary prevention system of lung cancer with the in-depth participation of traditional Chinese medicine(TCM).Methods A cross-sectional study was adopted to investigate patients with pulmonary nodules who admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from August 2023 to January 2024.Data collection covered the basic information,clinical characteristics and symptoms of the patients.Likert four-level scale was used for the grading of the severity of the symptoms,multivariate linear regression was adopted to construct three regression models,and then the factors influencing the severity of symptoms of patients with pulmonary nodules were explored.Results(1)A total of 274 patients were enrolled in the analysis,including 160 females and 114 males,with a mean age of(54.44±12.00)years old and the symptom scores averaging(3.97±3.80)point.The included patients with pulmonary nodules were characterized by females outnumbering males,a higher proportion of middle-aged and elderly people,multiple pulmonary nodules being more common.(2)The analysis of the symptoms of the 274 patients showed that symptoms with an incidence over 30%were fatigue(116 cases,42.34%),cough(105 cases,38.32%),expectoration of white sputum(89 cases,32.48%),and irritability and distress(87 cases,31.75%).(3)Multivariate linear regression analysis after variable adjustment suggested that the overall symptomatic severity in the male was milder than that in the female[β=-1.67,95%CI(-2.67,-0.68),P<0.001],and symptom score was positively correlated with age[β=0.07,95%CI(0.03,0.10),P<0.001],history of exposure to secondhand smoke[β=1.27,95%CI(0.26,2.27),P=0.015],history of exposure to other hazardous substances[β=1.96,95%CI(0.39,3.53),P=0.015],and history of allergy[β=2.38,95%CI(1.22,3.54),P<0.001]significantly.Conclusion The overall symptoms of patients with pulmonary nodules in Lingnan area are mild,and the high prevalence of symptoms are fatigue,cough,expectoration of white sputum,and irritability and distress.The symptom severity is correlated with gender,age,history of exposure to secondhand smoke,history of exposure to other hazardous substances,and history of allergy.

Objective To investigate the situation of sexual partners and related factors among men who have sex with men (MSM) in college students.Methods Snowball sampling and Convenience sampling were both used to recruit MSM from colleges in Tsingtao in 2016.Questionnaire-based interviews were conducted to collect data of socio-demographic and situation of sexual partners.Sample Size was estimated based on cross-sectional study,and theoretical 267.SPSS 17.0 software was used for statistical analysis.Results A total of 300 MSM,average aged 20.7,were analyzed.Both first sex partner and the last same-sex sexual partner were mct instantly,with proportions as 58.7％ (176/300) and 62.3％ (187/300) respectively.Among all the MSM,88.3％ (265/300) preferred selecting men as sex partners and 42.7％ (128/300) enjoyed finding sex partners in college,while 86.0％ (258/300) preferred finding their sex partners through intemet.Conclusions Intemet had been the major way of looking for sex partner among MSM in college students,the male sexual partner were met instantly.We should focus on men who have sex with men and their sexual health among college students to prevent and control HIV/AIDS.
