Objective To systematically evaluate the effectiveness of N-acetylcysteine (NAC) combined with low-dose glucocorticoid for patients with idiopathic pulmonary fibrosis (IPF). Methods Such databases as The Cochrane Library (Issue 12, 2012), EMbase (January 1974 to July 2012), PubMed (January 1966 to July 2012), CHEST (January 1995 to July 2012), CNKI (January 1994 to July 2012), CBM (January 1978 to July 2012), VIP (January 1989 to July 2012) and WanFang Data (January 1995 to July 2012) were searched to collect the randomized controlled trials (RCTs) about NAC combined with low-dose glucocorticoid versus glucocorticoid alone for IPF patients. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was performed using RevMan 5.1 software. Results A total of seven RCTs including 264 IPF patients were included. The results of meta-analysis demonstrated that, compared with the glucocorticoid used alone, a) NAC combined with low-dose glucocorticoid could significantly improve PaO2 (SMD=0.82 mmHg, 95%CI 0.30 to 1.35, P=0.002) and DLco (SMD=0.59 mmHg, 95%CI 0.16 to 1.03, P=0.008) with a significant difference. b) NAC combined with low-dose glucocorticoid could significantly improve all clinical symptoms (RR=1.56, 95%CI 1.26 to 1.92, Plt;0.000 1). Conclusion NAC combined with low-dose glucocorticoid for IPF patients can significantly improve PaO2, DLco, and the clinical symptoms such as cough, difficulty breathing after activities, cyanosis, and Velcro rales. Due to the quantity and quality limitation of included studies, this conclusion still needs to be further proved by more high quality and double blind RCTs.
ObjectiveTo systematically review the clinical efficacy of low-dose erythromycin in patients with stable chronic obstructive pulmonary disease (COPD). MethodsRandomized controlled trials (RCTs) about low-dose erythromycin plus routine treatment versus routine treatment/placebo plus routine treatment in treating stable COPD was electronically searched in PubMed, EMbase, CBM, The Cochrane Library (Issue 4, 2013), CNKI, VIP and WanFang Data from the their establishment dates to May 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. The results of meta-analysis was performed using RevMan 5.2 software. ResultsA total of eight RCTs involving 526 patients were finally included. The results of metaanalysis showed that:a) compared with the control group, low-dose erythromycin significantly improved six-minute walk distance (SMD=0.30, 95%CI 0.05 to 0.55, P=0.02), reduced the frequency of acute exacerbation (RR=0.44, 95%CI 0.25 to 0.78, P=0.005), and decreased the concentrations of IL-8 (SMD=-1.63, 95%CI-2.17 to-1.09, P < 0.000 01), TNF-α (SMD=-1.49, 95%CI-2.36 to-0.62, P=0.000 8), and neutrophil elastase (NE) (SMD=-0.94, 95%CI-1.36 to-0.51, P < 0.000 1) in sputum. b) the erythromycin therapy could improve forced expiratory volume in one second (FEV1) (SMD=0.19, 95%CI-0.19 to 0.58, P=0.32) but without significant differences compared with the control group. ConclusionLow-dose erythromycin could improve exercise tolerance, reduce the frequency of acute exacerbation, and help relieve airway inflammation, but in the improvement of FEV1, low-dose erythromycin is not better than routine treatment. Due to limited quantity and quality of the included studies, larger scale, multicenter, high quality RCTs are needed to verify the aforementioned conclusion.
目的 对糖尿病急性代谢并发症小剂量胰岛素的应用方法及技巧进行探讨和分析。 方法 以2009年1月-2012年2月收治的50例糖尿病急性代谢并发症患者为研究对象,按照数字随机表方法分为对照组和试验组,每组25例患者。对照组患者在小剂量胰岛素的使用上采用常规技巧和方法;试验组患者在小剂量胰岛素的使用上结合实际情况和相关规范进行综合治疗,比较两组患者小剂量胰岛素的应用效果。 结果 经治疗,对照组18例患者的临床症状得到明显改善,显效率为72%;试验组25例患者的临床症状均得到有效缓解,显效率为100%,两组患者的显效率比较,差异有统计学意义(P<0.05)。 结论 使用小剂量胰岛素治疗糖尿病急性代谢并发症患者时,结合实际情况和相关规范进行综合治疗临床效果满意。
ObjectiveTo explore the effects of small dose and low pressure lavage on gastrointestinal hemorrhage induced by acute poisoning. MethodsWe collected the clinical data of all the patients diagnosed as gastrointestinal hemorrhage induced by acute poisoning treated between January 2011 and December 2012. The patients were divided into two groups: control group and treatment group, according to the different treatments they underwent. The control group received traditional treatment only, while the treatment group received small dose and low pressure lavage as well as the traditional treatment. After recording the ages, poisoning dose, pretreatment time, shock and complications, we evaluated the risk of death by calculating ROCKALL scores. ResultsThe differences of ages, sexes, and poisoning dose between these two groups were not significant. However, the death rate in high and middle risk patients of the treatment group was significantly lower than that of the control group (P<0.05). ConclusionThe small dose and low pressure lavage can improve the prognosis of the gastrointestinal hemorrhage induced by acute intoxication.
