Objective To investigate the current situation and influencing factors of social phobia in patients with gastrointestinal neoplasms, and to provide evidence for psychological intervention and improving the quality life of patients with gastrointestinal neoplasms. MethodsGastrointestinal neoplasms patients admitted to the Colorectal Cancer Center Ward of West China Hospital, Sichuan University between December 2021 and March 2022 were continuously included. A self-made questionnaire, social phobia behavior professional test scale, and social support rating scale were used to investigate the included patients and analyze the possible influencing factors of social phobia in patients. Results A total of 483 patients were included. Among them, there were 299 males and 184 females. The median score of social support rating scale was 37 (31, 42), with 80.54% of patients received average levels of social support. The median score of social phobia behavior professional test scale was 14 (11, 17), with 98.34% of patients had mild social phobia symptoms and 1.66% had moderate social phobia symptoms. There were statistically significant differences in social phobia behavior professional test scale scores among patients with different levels of education and average monthly income. The results of multiple linear regression analysis showed that the average monthly income was a influencing factor for patients’ social phobia. Conclusions Generally, patients with gastrointestinal neoplasms have mild social phobia. However, patients with fixed income had a higher risk to suffer social phobia were compared to those without income. It is suggested that clinical workers should pay more attention to the mental health of gastrointestinal neoplasms patients and prevent the occurrence of anxiety and phobia.
ObjectiveTo observe the effect of thermal damage in the fresh isolated kidneys of New Zealand white rabbits caused by domestic holmiumlaser. MethodsIn the operation room (constant temperature 22℃, humidity 60%), Guangdong electric (POTENT) domestic holmium laser equipment was chosen. The fresh isolated kidney of New Zealand white rabbit was put into a disposable sterilized syringe with 50 mL normal saline, then the holmium laser optical fiber (550 μm) was put into it, and the temperature of normal saline was measured by a mercury thermometer. The parameters of holmium laser were setted as frequency 20 Hz, energy 2 J, stimulating time 15 seconds, intermittent time 5 seconds, which was repeated. The temperature was measured 2, 5 and 7 minutes after stimulation. Then the kidney was dissected, phtographed, haematoxylin-eosin stained, and pathologically examined.ResultsAt the 2nd minute of stimulation, the temperature of normal saline in the syringe increased from 22℃ to 38℃; the cortex and medulla of rabbit kidney were ruddy, and the cortex, medulla and ureter were almost normal in pathological section. At the 5-minute point, the temperature increased to 57℃, and the cortex turned to be white, while the medulla remained ruddy, but the demarcation between the cortex and medulla was not very clear. At the 7th minute, the temperature was 78℃, and the cortex and medulla were both white and solidification with no clear demarcation. Pathological examination showed severe degeneration and necrosis of glomerulus and renal tubule.ConclusionCommon power of domestic holmium laser would produce increasing thermal damage, which may cause tissue damage in the human body when the temperature increases above 50℃.
