前列腺源性ETS因子在哮喘及鼻黏膜炎性疾病中的研究进展

含SAM尖端结构域的E26转化特异性因子(SPDEF)是ETS转录因子家族的最新成员之一, SPDEF又称为前列腺源性ETS因子(PDEF),首次发现其在前列腺癌中高度表达,参与肿瘤细胞的增殖分化、迁移凋亡和血管形成。近年来研究发现SPDEF与杯状细胞增生和分化密切相关,是调控呼吸道黏液高分泌的核心因子。对SPDEF调控黏液高分泌的机制及其在呼吸道慢性炎性疾病中的研究进展做一综述,以期为呼吸道黏液高分泌疾病的发病机制和诊治提供新思路。     

三伏贴联合伏针闪罐治疗支气管哮喘的临床观察

目的采用三伏贴联合伏针闪罐治疗支气管哮喘,观察该治疗方法对支气管哮喘患者的临床疗效。方法选择秦皇岛市中医医院针灸科2016年9月至2019年9月三伏期间收治的符合诊断及纳入标准的120例支气管哮喘患者,按照随机数字表法随机分为治疗组和对照组,每组60例,治疗组采用三伏贴联合伏针闪罐疗法,对照组单用三伏贴疗法。三伏期间初伏、中伏和末伏各贴敷1次,共贴敷9次,3年为1个疗程。1个疗程后,采用χ^2检验比较2组总有效率。结果治疗组治愈27例,好转31例,无效2例,治愈率45. 0%(27/60),总有效率96. 6%(58/60);对照组治愈14例,好转37例,无效9例,治愈率23. 3%(14/60),总有效率85. 5%(51/60)。治疗组治愈率和总有效率均高于对照组,且差异有统计学意义(χ^2=6. 261、4. 904,P均<0. 05)。结论三伏贴联合伏针闪罐治疗支气管哮喘疗效优于单纯三伏贴治疗,充分发挥中医特色优势,值得在临床上推广应用。     

Impact of training on use of inhalational techniques of different inhaler devices: A single institutional cross sectional observation study

ObjectiveTo assess the impact of training on use of inhalational techniques of different inhaler devices in spirometry proved cases of COPD and Bronchial Asthma in a tertiary care centre.MethodsA total of 128 spirometry proved cases of Asthma and COPD were enrolled. They were equally distributed in four groups comprising of 32 patients each according to their inhalation devices namely pMDI, Rotahaler, Accuhaler and Turbohaler. Patients were asked to demonstrate their inhalation technique and errors were noted according to their inhaler specific checklist. Patients were also interviewed regarding their knowledge about inhalation devices. Training about proper inhalation techniques was given to every participant. Rechecking of inhalation technique was again done at the second visit after 2 wks in the similar manner. Correct and incorrect steps of inhalation technique again evaluated by filling the checklist of the individual device to see post training improvement.ResultIn our study, out of total cases more than one third of the patients were >60 yrs of age (41.4%) and most of the patients were males (62.5%). During the interview at first visit, almost 92% patients claimed to know how to use the inhalation device correctly but in reality most of the patients (around 96.1%) had committed at least one mistakes in their inhalation technique among all the inhalation steps. Errors were noted in different steps of inhalation including the essential steps among all the four devices. Statistically significant improvement in inhalation techniques including the essential steps were found among all the four devices after educational intervention and demonstration of sequential steps involved in particular inhaler.ConclusionOur study confirmed a significant increase in the percentage of improvement in inhalation technique after proper demonstration and training about the inhalation devices. Inhalation technique including essential steps of inhalation significantly improved in all the four devices used.
