【摘要】目的探讨喉癌手术后患者对两种不同雾化方式的耐受性,为选择最佳雾化方式提供参考。方法将49例喉癌手术后患者随机分为观察组(25例)和对照组(24例),观察组采用氧气雾化吸入,对照组采用空气压缩泵雾化吸入。分别记录两组患者雾化吸入前及吸入15 min时脉搏血氧饱和度(SpO2)及心率;雾化过程中患者有无心慌、气紧等不适以及雾化后痰液的性质及量。采用SPSS 13.0软件进行统计分析。结果两组患者雾化吸入15 min时的SpO2差异有统计学意义(Plt;001),观察组高于对照组;而两组患者雾化吸入前SpO2、心率、不适主诉及雾化后痰液的性质差异均无统计学意义(Pgt;005)。结论氧气雾化吸入可以提高喉癌手术后患者雾化过程中的SpO2,使患者感觉更加舒适。【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 observe the changes of macular visual function after myopic foveoschisis (MF) and pars plana vitrectomy (PPV) combined with internal limiting membrane peeling and air filling. MethodsA single-center, retrospective study. From October 2018 to October 2019, 29 MF inpatients (32 eyes) in Tianjin Eye Hospital were included in this study. There were 3 males (4 eyes) and 26 females (28 eyes). The age was 63.00±3.45 years old. Equivalent spherical lens degree was －14.16±2.54 D, and axial length was 29.14±1.04 mm. Among them, 3 patients (3 eyes) had lamellar macular holes. All eyes underwent standard pars plana three-channel 25G PPV combined with internal limiting membrane peeling and air filling. Before surgery and at 1, 3, and 6 months after surgery, macular microperimetry was performed with a macular integrity assessment instrument, and the mean retinal sensitivitie (MS) within 10° of the macula, fovea 2° and 4° fixation rates (P1, P2), 63% and 95% bivariate contour ellipse area (BCEA) were recorded. The comparison of MS, P1, P2, 63%BCEA and 95%BCEA at different times before and after surgery was performed by paired t test; the comparison of fixation stability rate was performed by χ2 test. ResultsCompared with before surgery, there were significant differences in the improvement of MS in affected eyes at 1, 3 and 6 months after surgery (t=－2.208, －3.435,－4.919; P=0.038, 0.002, 0.000). In the pairwise comparison at different times after surgery, only 6 months after surgery and 1 month after surgery were significantly different (P=0.036). Compared with the preoperative P1, P2, 63%BCEA and 95%BCEA, the P1 and P2 of the eyes gradually increased after surgery, while the 63%BCEA and 95%BCEA gradually decreased, however, the difference was not statistically significant (P1: t=－1.595,－1.698,－1.966; P=0.125, 0.104, 0.062. P2: t=－1.622,－1.654,－1.707; P=0.119, 0.112, 0.102. 63%BCEA: t=1.410, 1.409, 1.553; P=0.172, 0.173, 0.135. 95%BCEA: t=1.412, 1.408, 1.564; P=0.172, 0.173, 0.132). Six months after surgery, all the eyes underwent anatomical repositioning of the macular area, and no serious complications such as full-thickness macular hole and macular hole retinal detachment were found. ConclusionsPPV with internal limiting membrane peeling and air filling is an effective and safe method for MF, and the macular function improved significantly within 6 months postoperatively.

ObjectiveTo observe and explore the feasibility and effectiveness of platelet-rich fibrin (PRF) membrane packing and air filling in the treatment of refractory macular holes. MethodsA retrospective clinical study. From January 2019 to January 2020, 17 patients with refractory macular hole (17 eyes) who diagnosed in Renmin Hospital of Wuhan University were included in the study. Among them, there were 7 males (7 eyes) and 10 females (10 eyes), with the age of 55.18±7.91 years. All eyes underwent 23G minimally invasive vitrectomy combined with internal limiting membrane stripping and PRF packing, and air filling was performed at the end of the operation. The best corrected visual acuity (BCVA) and optical coherence tomography angiography were performed in all eyes before surgery and at 1 week and 1, 3 months after surgery. The BCVA examination was performed using a international standard logarithmic visual acuity chart, which was converted into logarithm of the minimum angle of resolution visual acuity during statistics. Taking 3 months after surgery was as the time point to judge the efficacy, the changes of BCVA, superficial retinal vascular density (SVD), foveal avascular zone (FAZ) area and central foveal thickness (CFT) before and after surgery were compared. Paired t-test was used to compare the indicators before and after surgery. ResultsAmong the 17 eyes, there were 6, 7, and 4 eyes with giant macular hole, high myopia macular hole, and recurrent macular hole, respectively; the hole diameter was 723.94±38.30 μm. Three months after surgery, all holes were closed. Compared with before surgery, the BCVA (t=4.458) and SVD (t=2.675) increased, and the CFT (t=6.329) and FAZ area (t=4.258) decreased at 3 months after surgery, and the differences were statistically significant (P<0.05). At the last follow-up, there was no complications such as intraocular hypertension and retinal detachment in all eyes.ConclusionMinimally invasive vitrectomy combined with internal limiting membrane stripping and PRF tamponade in the treatment of refractory macular holes can increase the closure rate, improve visual acuity and retinal blood perfusion.
ObjectiveTo explore the correlation of respiratory diseases in respiratory clinic with air quality and temperature in winter. MethodsThe data of patients in the respiratory clinic in Anyang District Hospital were collected from November 1, 2012 to February 28, 2013. The air quality and weather condition were investigated in the local environmental protection department and meteorological department simultaneously. The number of outpatients,prevalence of main symptoms and main respiratory diseases as preliminary diagnoses were recorded. Their relations with air pollution index (API) and air temperature were analyzed. ResultsPearson correlation coefficient of daily API with the outpatients number of the day,the next 1 day and the next 3 days were 0.725, 0.331 and 0.257, respectively (P<0.01), which indicating a positive correlation. The average number of outpatients per day increased by 21.4%, 42.6% and 50.4%, respectively with increased API scale, so did the prevalence of main symptoms and that of main respiratory diseases as preliminary diagnoses. Pearson correlation coefficient of API with cough with sputum, and asthma were 0.287 and 0.277, respectively (P<0.01), which indicating a positive correlation. Pearson correlation coefficient of API with upper respiratory infection, bronchitis, bronchial asthma, and pneumonia were 0.184, 0.251, 0.301 and 0.227, respectively (P<0.05), which indicating a positive correlation. The average number of outpatients was stable when temperature ranged from -3℃to 15℃,increased by 34.5% when temperature ranged from -4℃to -3℃,and increased by 9.3% more when temperature ranged from -5℃to -4℃. Cough was more sensitive to air temperature, and the prevalence of cough increased by 35.7% when temperature ranged from -4℃to -3℃,and increased by 14.0% more when temperature ranged from -5℃to -4℃. Pearson correlation coefficient of air temperature with sinusitis, bronchial asthma, and sputum were -0.194, -0.383 and -0.191, respectively (P<0.05), which indicating a negative correlation. ConclusionsIn winter,the number of outpatients increases with the increase of API. Respiratory diseases and symptoms are closely related to air quality and temperature.
