RESUMO
Objective:To analyze the mental health status of men who have sex with men (MSM) population among acquired immunodeficiency syndrome (AIDS) patients.Methods:A face-to-face questionnaire survey was conducted to investigate the general information, symptom check list-90 (SCL-90) questionnaire and scale of 269 MSM patients with AIDS in the Eighth Hospital of Xi'an city from November 2015 to May 2016.Results:Among the 269 cases of MSM with human immunodeficiency virus (HIV)/AIDS, the majority were 20-40 years old, with higher education level, mostly unmarried and nonsingleton. The scores of each factor of SCL-90 were significantly higher than that of the norm, among which diet and sleep, interpersonal relationship, anxiety and depression were the most prominent; regression analysis showed that the main reason affecting the scores of each factor among AIDS patients was the low quality of life, and the patients with high education were more likely to have depression and anxiety.Conclusions:MSM has its own special characteristics among AIDS patients, and there are many psychological problems. Necessary psychological intervention measures should be given.
RESUMO
Objective To use the liquid protein combined with MALDI-TOF-MS for screening the serum differential peptides markers in lung adenocarcinoma patients and to establish the lung adenocarcinoma diag-nosed prediction model for founding the potential markers for the diagnosis of lung adenocarcinoma.Methods 37 patients with lung adenocarcinoma and 33 healthy subjects and benign lung disease which were made up in control group were collected,in the two groups the age and the sex were matched.The two groups were ran-domly divided into training group(30 cases of lung adenocarcinoma,26 cases of control)and test group(7 ca-ses of lung adenocarcinoma,7 cases of control)according to 3:1.T he differential diagnosis of lung adenocarci-noma and control group was performed by liquid chip-time-of-flight mass spectrometry and software ClinPro-Tools 3.0 to establish a prediction model of lung adenocarcinoma.The diagnostic model was validated by using serum samples from the test group to assess the diagnostic efficacy of the model.Results Nine peptide peaks with significant differences(P<0.05)were obtained by ClinProTools 3.0 software analysis.The up-regulated peaks in lung adenocarcinoma(m/z)were 8 976.5,4 469.05,4 966.78,8 925.5,4 531.05,and the down-reg-ulated m/z were 3 304.44,8 594.76,3 266.82,3 195.52.According to the genetic algorithm(GA),the lung ad-enocarcinoma diagnosis and prediction model was established.The overall recognition ability of the model was 94.49%.The model was evaluated by the test group.The results showed that the sensitivity of the model was 100.0% and the specificity was 85.7%.Conclusion Among lung adenocarcinoma patients,serum benign lung disease and healthy,there are differences in the serum peptide.T he use of differential peptide peaks to estab-lish lung adenocarcinoma diagnostic prediction model for the early diagnosis of lung adenocarcinoma provides a new method.
