Objective To evaluate the diagnostic accuracy of Wilson score for predicating difficult intubation. Methods Such databases as PubMed, EMbase, CNKI, WanFang Data and VIP were searched to collect the studies about Wilson score for predicating difficult intubation published from inception to January 2013. Two reviewers independently screened the studies, extracted the data, and assessed the methodological quality by QUADAS. The analysis was conducted by using Meta-Disc 1.4 software, and the random effect model was chosen to calculate the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and the 95%CI. The summary receiver operating characteristic (SROC) curve was drawn and the area under the curve (AUC) was calculated in order to comprehensively assess the total diagnostic accuracy of Wilson score for predicating difficult intubation. Results A total of 9 studies involving 6 506 subjects were included. The results of meta-analysis showed that: the pooled sensitivity was 0.57 (95%CI 0.53 to 0.62), specificity was 0.89 (95%CI 0.88 to 0.90), positive likelihood ratio was 6.11 (95%CI 4.63 to 8.07), negative likelihood ratio was 0.52 (95%CI 0.41 to 0.66), diagnostic odds ratio was 12.76 (95%CI 8.60 to 18.93), and the AUC of SROC was 0.84. Conclusion Wilson score plays a role in predicating difficult intubation, while some other clinical indicators also need to be taken into consideration in its application.
Objective To assess the quality of reporting of randomized controlled trials (RCTs) related to traditional Chinese medicine (TCM) published in the Chinese Journal of Evidence-Based Medicine by CONSORT statement and Jadad scale. Methods We handsearched the Chinese Journal of Evidence-Based Medicine to identify TCM RCTs. The revised CONSORT statement and Jadad scale combined with self-established criteria were applied. Results A total of 57 RCTs were identified of which there were 17 TCM RCTs. Some items in CONSORT checklist were completely reported in all TCM RCTs, such as abstract, inclusion and exclusion criteria, intervention, randomization sequence generation, description of statistic method, description of baseline data, outcomes and estimation, and explain results. Compared with the previous findings, there were more trials in this study to report allocation concealment, randomization implementation, use of flow chart and appliance. Only 3 RCTs (17.6%) reported acknowledgements. One RCT did not describe syndrome type of TCM, and 4 RCTs (23.5%) carried out dummy. The mean Jadad score was 4.35±1.11 in all trials, of which 11 RCTs (64.7) ranked 5 points. Conclusion The comprehensive quality of reporting of TCM RCTs published in the Chinese Journal of Evidence-Based Medicine from 2001 to 2008 has been improved. After the publication of CONSORT statement and CONSORT for traditional Chinese medicine, the quality of reporting of TCM RCTs is improved. We are looking forward to improving the CONSORT for TCM.
【摘要】 目的 总结慢性阻塞性肺疾病（chronic obstructive pulmonary disease，COPD） 患者院外用药情况，并分析其院外用药情况、痰真菌检出率以及激素不良反应发生率的变化。 方法 调查2011年1-6月住院的161 例COPD 患者院外用药情况，将其分为遵医嘱使用糖皮质激素组（A组，包括口服和吸入激素）、使用非准字号药物组（B组）和未使用以上两种药物组（C组），对各组的痰真菌检出率进行统计学分析，并对A、B组激素不良反应的发生率进行分析。再将现阶段的调查结果与2006年同样研究结果进行比较。 结果 161例患者中使用口服糖皮质激素6例，使用吸入激素29例，使用非准字号药物32例，未使用以上两种药物94例。痰真菌检出率情况:B组检出率为62.5%，明显高于A组的17.14%、C组的27.66%；组间比较有统计学意义（Plt;0.001）。B组的药物不良反应发生率为37.5%；A组中口服激素发生率为50%，而使用吸入激素发生率为0%。与2006年同样研究结果比较，B组患者的比例明显下降，A组患者明显增多。 结论 使用非准字号药物的患者，真菌感染的危险性及激素不良反应的发生率较高，健康教育对于减少这些不良现象的发生发挥了重要作用。【Abstract】 Objective To investigate the use of drugs in patients with chronic obstructive pulmonary disease (COPD) outside the hospital, and analyze the detection rate of fungus and the side effects of glucocorticosteroids (GCs), and their changes. Methods We investigated the drugs used outside the hospital in 161 patients with stable COPD between January and June 2011, who were divided into prescribed medication GCs group (group A, including oral GCs group and inhaled GCs group), drugs without authorization by SFDA (DWAS) group (group B) and other drugs group (group C). Then we made a statistical analysis on the detection rate of fungus, and the incidence rate of the side effects of GCs in the three groups. Finally we compared the present findings with the similar studies five years ago. Results Among the 161 patients, 6 took oral GCs, 29 used inhaled GCs, 32 used DWAS, and 94 used other drugs. The detection rate of fungus in group B was 62.5%, obviously higher than the other groups (17.14% in group A, and 27.66% in group B, Plt;0.05). The rate of side effects of GCs in group B was 37.5%, and 50% in oral GCs group, while no side effects of GCs was found in the inhaled GCs group. Compared with the similar study five years ago, the use of DWAS decreased, and the use of prescribed medication GCs among the patients increased significantly. Conclusions Patients taking DWAS have a high incidence rate of mycotic infection and side effects of GCs. Health education plays an important role in reducing the occurrences of these undesirable phenomena.
Objective To systematically assess the effectiveness of traditional Chinese medicines (TCM) in treating upper airway cough syndrome (UACS) or postnasal drip syndrome (PNDS). Methods Such databases as MEDLINE (1950 to 2011), PubMed (1996 to 2011), VIP (1989 to 2011), WanFang Data (1998 to 2011), CNKI (1979 to 2011) and CBM (1978 to 2011) were searched for collecting the randomized controlled trials (RCT) or quasi-RCTs about TCM treating UACS/PNDS. The trials were screened according to the inclusive and exclusive criteria, and then after the quality assessment and data extraction were conducted, the statistical analysis was conducted by using RevMan 5.0 software. Results A total of 10 RCTs and quasi-RCTs in Chinese were identified. The results of analysis showed that: a) The integrated Chinese and western medicine was superior to western medicine alone, either for adults and children with UACS, or for adults with PNDS. However the effectiveness had to be further assessed due to lack of high-quality literatures; b) TCM alone was probably more effective than western medicine alone for adults with PNDS, but not for adults and children with UACS. No obvious adverse reaction related to TCM was reported. Conclusion The recent research outcomes show that the integrated Chinese and western medicine is superior to western medicine alone, either for adults and children with UACS, or for adults with PNDS, but no definite evidence is found to support the superiority of TCM in treating UACS/PNDS. More high-quality RCTs with large scale need to be conducted in future to verify this conclusion due to the overall low methodological quality and significantly different intervention of the included trials.
目的 评估中医药临床研究是否与我国主要疾病负担相关。 方法 首先从1999年－2004年出版的13种中医、中西医结合杂志中手工检索出随机对照试验（RCT），并提取出杂志名称、出版年限、治疗的疾病类别及样本含量等数据。然后采用死亡率和伤残调整寿命年（DALY）作为衡量标准，统计2002年我国疾病负担前30位病因的RCT数量，采用秩相关分析这些疾病负担与发表的中医药RCT及其受试者数量的关系。 结果 最终确认7 422个RCT，约38%的RCT来自于3种国家级杂志。这些RCT覆盖了我国疾病负担中的主要病种，其中4 280个RCT（57.7%）研究前30位病因合并产生的42个病种，只有3个病种（7%）没有任何RCT研究。采用DALY得到的相关系数分别是0.108（P=0.569）、0.092（P=0.628），通过死亡率产生的相关系数分别是0.453（P=0.012）、0.536（P=0.002）。 结论 中医药RCT与采用死亡率衡量的疾病负担明显相关，但采用DALY分析却未发现二者存在相关性。中医药临床研究可能更注重死亡率高的病种，一定程度上忽略了DALY衡量的疾病负担。
Objective To evaluate the efficacy and safety of Huo Xiang Zhengqi dropping pill in treating wind cold and dampness stagnation pattern of common cold. Methods A multicenter, randomlyized, double blind, double dummy, controlled trial was conducted. A total of 480 patients with common cold were randomly divided into two groups: a trial group (360 patients) were treated with Huo Xiang Zhengqi Dropping Pill and Huo Xiang Summer-heat Eliminating Soft Capsule analogue, while a control group (120 patients) were treated with Huo Xiang Summer-heat Eliminating Soft Capsule and Huo Xiang Zhengqi Dropping Pill analogue. The therapeutic course of both groups was 3 days. Results The therapeutic effectiveness of diarrhea as the main symptom: the marked effective rate and total effective rate of the trial group were 86.1% and 96.1%, respectively, while those of the control group were 69.2% and 84.6%, respectively; the therapeutic effectiveness of traditional Chinese medicine (TCM) pattern: the marked effective rate and total effective rate of the trial group were 87.5% and 98.5%, respectively, while those of the control group were 69.2% and 91.5%, respectively. There were significant differences between the two groups in terms of the above two indicators (Plt;0.05), which indicated Huo Xiang Zhengqi Dropping Pill was superior to Huo Xiang Summer-heat Eliminating Soft Capsule in treating wind cold and dampness stagnation pattern of common cold. No adverse effects were found in the trial group. Conclusion Huo Xiang Zhengqi Dropping Pill is effective and safe in treating wind cold and dampness stagnation pattern of common cold.
