ABSTRACT
Objective To investigate the effect of personality characteristics on near-term postoperative mental health of patients with laryngeal squamous cell carcinoma (LSCC). Methods We included 119 patients with LSCC who underwent surgical treatment. The recent psychological state was assessed by SCL-90, SAS and SDS 5 to 7 days after surgery. The EPQ was used to evaluate the personality characteristics of patients after operation. Multiple linear stepwise regression method was used to analyze the influencing factors of SAS and SDS scores of LSCC patients. Results The postoperative scores of SCL-90, SAS and SDS of LSCC patients were significantly higher than the Chinese norm (P≤0.05). The scores of P scale and N scale in EPQ were higher than the domestic norm (P < 0.01). The scores of somatization, obsessiveness, anxiety, depression, hostility, phobia, paranoia and psychosis were significantly higher than the Chinese norm (P < 0.05). Family income, surgical method, postoperative radiochemotherapy, psychoticism and neuroticism personalities were the influencing factors of postoperative SAS score (P < 0.01). Family income, surgical method, postoperative radiochemotherapy, neurotic personality were the influencing factors of postoperative SDS score (P < 0.01). Conclusion LSCC patients have near-term depression, anxiety and other psychological disorders after operation. In terms of personality, they have psychoticism and neuroticism. Family income, surgical methods, postoperative radiochemotherapy, psychoticism and neuroticism are independent risk factors affecting postoperative SAS and SDS scores.
ABSTRACT
Objective To establish two-dimensional electrophoresis profiles of laryngeal squamous carcinoma tissue with high resolution and reproducibility. Methods The total protein of well-differentiated or poorly-differentiated laryngeal cancer tissue was separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). The differential expression protein was analyzed by using ImageMaster 2D analysis software. Results We obtained fine resolution, reproducible 2-DE patterns of well-differentiated and poorly-differentiated laryngeal squamous carcinoma. Differential expression protein spots were defined in 2-DE gels. Thirteen protein spots were preliminarily identified, among which seven proteins were upregulated in well-differentiated laryngeal cancer tissue, six were downregulated. Conclusion The expression map of proteomics was established for well-differentiated and poorly-differentiated laryngeal cancer, which was of significant difference between them. Laryngeal cancer proteome might reflect the underlying pathological state.
