柳氮磺胺吡啶联合培菲康治疗溃疡性结肠炎的临床研究 总被引:2,自引:0,他引:2
目的探讨柳氮磺胺吡啶联合培菲康治疗溃疡性结肠炎患者的临床疗效。方法将52例溃疡性结肠炎患者随机分成两组。治疗组采用柳氮磺胺吡啶联合培菲康治疗(n=27);对照组单纯采用柳氮磺胺吡啶治疗(n=25),观察两组患者治疗后临床活动指数及临床综合疗效。结果两组治疗前临床活动指数:治疗组为7.85±2.93,对照组为7.68±2.88,两组差别无统计学意义(P〉0.05),治疗后临床活动指数治疗组为1.56±1.78,对照组为3.64±2.50,两组均较治疗前下降了(P〈0.001),但治疗组临床活动指数的改善优于对照组(P〈0.05);治疗后两组临床综合疗效比较,治疗组完全缓解20例,有效5例,无效2例,总有效率92.6%,对照组完全缓解11名,有效6例,无效8例,总有效率68%,治疗组临床综合疗效也优于与对照组,两组完全缓解率和总有效率有显著差别(P〈0.05)。结论柳氮磺胺吡啶联合培菲康治疗溃疡性结肠炎患者有利于临床症状的好转,提高临床疗效。 相似文献

BackgroundTo assess the temporal changes in the characteristics of ischemic stroke drug clinical trials conducted in mainland China in 2005–2021.MethodsA statistical analysis of registered clinical trials on ischemic stroke was performed using the platform of the Center for Drug Evaluation of China National Medical Products Administration, the Chinese Clinical Trial Registry, and ClinicalTrials.gov websites.ResultsFrom January 1, 2005 to August 1, 2021, a total of 384 registered drug clinical trials on ischemic stroke were identified in mainland China. Over time, the number of trials gradually increased each year, with a significant growth in 2014, from 16 in 2013 to 42 in 2014. Phase IV trials (31.8%) accounted for the majority, followed by phase II (16.4%), phase I (10.9%), and phase III (8.6%). In terms of sponsorship, the proportion of investigator‐initiated trials (IITs) (60.7%) was higher than industry‐sponsored trials (ISTs) (39.3%). Additionally, trials involving traditional Chinese medicines (TCMs) (36.2%) accounted for the largest proportion, followed by trials involving antithrombotic therapy (19.5%) and cerebral protection agents (16.7%). Furthermore, over the past 17 years, the number of leading drug clinical trial units for ischemic stroke in mainland China has continuously increased. The leading principal units from Beijing, Shanghai, Guangdong, Jiangsu, and Liaoning accounted for the majority of the trials (67.4%).ConclusionIn the past 17 years, great progress has been made in the research and development (R&D) of drugs and clinical trials for ischemic stroke in mainland China. The most extensive progress was observed in TCMs, antithrombotic therapy, and cerebral protection agents. More clinical trials are needed to confirm whether the newly developed drugs can improve the clinical efficacy of ischemic stroke. Simultaneously, more pharmaceutical R&D efforts of innovative drugs are warranted. 相似文献

Introduction:Peripheral facial palsy (PFP) results in weakness or paralysis of the affected side of the face. In Korea, there is a high demand for Korean medicine treatment for PFP. The clinical practice guidelines (CPGs) of Korean medicine for facial palsy were developed; however, there remains insufficient evidence to support the effectiveness and safety of Korean medicine treatment. Thus, this study aimed to evaluate the effectiveness and safety of Korean medicine treatment based on the CPGs in patients with acute PFP.Methods:This is a multicenter, prospective, observational study. The participants will be recruited from one Korean medicine hospital and eight Korean medicine clinics. The participants will receive Korean medicine treatments based on the CPGs, fill in survey questionnaires, and undergo electrophysiologic testing. The changes in House-Brackmann (H-B) grade, movement of the lip and eye, symptoms related to or accompanied by facial palsy, Facial Disability Index, EuroQol 5-dimension 5-level (EQ-5D-5L), and EuroQol Visual Analogue Scale (EQ-VAS), and the results of electromyography (EMG), electroneurography (ENoG), and Blink Reflex test will be analyzed. For the safety analysis, adverse events will be recorded, and for the feasibility analysis, the results of the Was It Worth It questionnaire will be assessed.Conclusion:We expect to draw real-world clinical data on the effectiveness and safety of Korean medicine treatment based on the CPGs in patients with acute PFP from this study. It would be the basis for complementing and improving the CPGs and provide the basis of clinical and policy decision-making.Trial registration:This study was approved by the Institutional Review Board of Kyung Hee University Korean Medicine Hospital (2021-06-005-001), and registered with the Korean Clinical Trial Registry (CRIS), Republic of Korea (KCT0006562). 相似文献
