【摘要】目的探討喉癌手術后患者對兩種不同霧化方式的耐受性,為選擇最佳霧化方式提供參考。方法將49例喉癌手術后患者隨機分為觀察組(25例)和對照組(24例),觀察組采用氧氣霧化吸入,對照組采用空氣壓縮泵霧化吸入。分別記錄兩組患者霧化吸入前及吸入15 min時脈搏血氧飽和度(SpO2)及心率;霧化過程中患者有無心慌、氣緊等不適以及霧化后痰液的性質及量。采用SPSS 13.0軟件進行統計分析。結果兩組患者霧化吸入15 min時的SpO2差異有統計學意義(Plt;001),觀察組高于對照組;而兩組患者霧化吸入前SpO2、心率、不適主訴及霧化后痰液的性質差異均無統計學意義(Pgt;005)。結論氧氣霧化吸入可以提高喉癌手術后患者霧化過程中的SpO2,使患者感覺更加舒適。【Abstract】Objective To investigate postoperative patients with laryngeal carcinoma atomization of two different forms of tolerance, in order to choose the best means of atomization. Methods Fifty postoperative patients with laryngeal carcinoma were divided into observation group using oxygen inhalation and control group using the air compression pump inhalation. Two groups of patients were recorded the value of SpO2 and heart rate before 15 minutes after the inhalation,as well as the discomforts such as flustered,gas tight during the atomization process and the nature and olume of sputum. Results The results of two groups of patients at the time of 15 minutes inhalation SpO2 statistically significant difference (Plt;001), the observation group than in the control group average SpO2 high; and two groups of patients with preinhalation SpO2 average, average heart rate, Discomfort chief complaint and the nature of sputum after aerosol compared no significant difference (Pgt;005). Conclusion Oxygen inhalation in patients with laryngeal cancer can improve the atomization process SpO2 value, so that patients feel more comfortable.
ObjectiveTo analyze the effects of alcohol consumption on oral flora of middle-aged and elderly men from the core area of southwestern China, and explore the relationship between excessive-alcohol-consumption-related flora and alcohol-related cancer.MethodsFrom March to June 2018, saliva samples of target subjects were collected for 16S ribosomal RNA gene sequencing, and a questionnaire survey which took drinking history of each participant as the target variable was conducted. According to the amount of alcohol consumed, the subjects were divided into non-drinking group, moderate-drinking group, and excessive-drinking group. The microbial analysis of α diversity, analysis of group difference of oral flora abundance, bacterial function prediction, and receiver operating characteristic (ROC) curve model prediction were carried out.ResultsA total of 59 subjects were included. There were 23 cases (39.0%) in the non-drinking group, 23 cases (39.0%) in the moderate-drinking group, and 13 cases (22.0%) in the excessive-drinking group. The average age was (61.90±8.85) years. Excessive drinking increased the abundance of oral flora (P<0.05), and could change the abundance of specific genus such as Peptostreptococcus and TM7［G-6］ (P<0.05) and regulate cancer-related pathways (P<0.05). ROC analysis found that a panel of three genus oral bacteria such as TM7［G-6］ might effectively distinguish the non-drinking group from the excessive-drinking group (area under curve=0.915).ConclusionsGenus of Peptostreptococcus and TM7_［G-6］ are the potential oral flora biomarkers for the excessive-drinking of target subjects. Some excessive drinking-related flora are closely related to oral cancer.
