ObjectiveTo analyze the impact of high-quality nursing care on adult patients with asthma and asthma control. MethodsWe randomly chose 100 patients with asthma from June 2012 to July 2013, and the patients were randomly divided into experimental group (n=50) and control group (n=50). Patients in both the two groups received treatments based on the characteristics of the patients' condition. The control group received conventional care, while the experimental group received high-quality nursing care aimed to help them establish the concept of Asthma Prevention on the basis of the conventional care. Then, we analyzed the effect of nursing intervention in both groups. ResultsBefore the treatment, the forced expiratory volume in 1 second (%) and peak expiratory flow were not significantly different between the two groups (P>0.05). After treatment, both groups had improvement in their lung function. However, improvement in lung function of the experimental group was significantly better than the control group (P<0.05). The disease remission level in the experiment group and the control group was respectively 86.0% (43/50) and 64.0% (32/50) (χ2=6.453, P=0.011). According to the Asthma Control Questionnare (5-item version), in the experimental group, 46 patients completed the assessment and the total control of asthma accounted for 34.8% (16/46), well-controlled asthma accounted for 50.0% (23/46), and uncontrolled asthma accounted for 15.2% (7/46); while in the control group, 48 patients completed the assessment and the total control of asthma accounted for 18.8% (9/48), well-controlled asthma accounted for 43.8% (21/48), and uncontrolled asthma accounted for 37.5% (18/48) (Z=-2.533, P=0.011). The average hospital stay for the experimental group and the control group was respectively 11.24 days and 12.16 days. ConclusionHigh-quality nursing care can improve the quality of life of adult asthma patients, improve the patients' lung function, and enhance the control of asthma.
Erythemato-squamous diseases are a general designation of six common skin diseases, of which the differential diagnosis is a difficult problem in dermatology. This paper presents a new method based on virtual coding for qualitative variables and multinomial logistic regression penalized via elastic net. Considering the attributes of variables, a virtual coding is applied and contributes to avoid the irrationality of calculating nominal values directly. Multinomial logistic regression model penalized via elastic net is thence used to fit the correlation between the features and classification of diseases. At last, parameter estimations can be attained through coordinate descent. This method reached accuracy rate of 98.34%±0.0027% using 10-fold cross validation in the experiments. Our method attained equivalent accuracy rate compared to the results of other methods, but steps are simpler and stability is higher.
Objective To evaluate the effectiveness and safety of chemotherapy regimens represented by pirarubicin (THP) vs. adriamycin hydrochloride (ADM) for non-Hodgkin lymphoma (NHL) in mainland China. Methods The randomized controlled trials (RCTs) about THP vs. ADM for treating NHL were collected in the databases such as CNKI, CBM, VIP and WanFang Data, and the references of the included studies were also retrieved manually, with the retrieval time from January 1989 to September 2012. According to the inclusion and exclusion criteria, two reviewers independently screened articles, extracted data, and assessed the methodological quality of the included studies. Then meta-analysis was performed using RevMan 5.0 software. Results A total of 15 RCTs involving 1 659 patients were included. The results of meta-analysis showed that: a) As for the total effective rate, the CTOP (C: cyclophosphamide, T: pirarubicin, O: vincristine, P: prednison) regimen was superior to the CHOP (C: cyclophosphamide H: adriamycin hydrochloride, O: vincristine, P: prednison) regimen with a significant difference (OR=1.07, 95%CI 1.02 to 1.12, P=0.006); and b) As for the safety, there were significant differences between the two groups in the incidence of cardiac toxicity (OR=0.42, 95%CI 0.30 to 0.57, Plt;0.000 01), gastrointestinal tract response (OR=0.69, 95%CI 0.56 to 0.85, P=0.000 5) and liver damage (OR=0.69, 95%CI 0.48 to 1.00, P=0.05). But no significant differences were found between the two groups in the incidence of mye1osuppression: the decreased hemoglobin (OR=0.83, 95%CI 0.61 to 1.14, P=0.25), leucopenia (OR=0.85, 95%CI 0.68 to 1.07, P=0.17), and thrombocytopenia (OR=0.99, 95%CI 0.70 to 1.39, P=0.95). Conclusion Based on the domestic evidences at current and compared with CHOP regimen represented by ADM, CTOP regimen represented by THP for treating NHL shows a higher total effective rate and less side effects. However, more high quality, large sample and double blind RCTs are required to prove this conclusion for the quality and quantity limitation of the included studies.
Objective To evaluate the efficacy of asarone injection in treating respiratory disease. Methods All the randomized controlled trials (RCTs) about treating respiratory disease with asarone injection were collected by searching MEDLINE (1990 to 2010), EMbase (1990 to 2010), CSJD (1989 to January 2010) and CNKI (1979 to December 2009). The assessment of methodological quality and data extraction of the included studies were performed independently by two reviewers, and Meta-analysis was conducted with RevMan 5.0 software. Results A total of 29 studies involving 3 931 patients met the inclusion criteria. The results of Meta-analysis showed that: a) Asarone injection was effective in treating respiratory diseases including bronchiolitis, chronic obstructive pulmonary diseases (COPD) and AECOPD, bronchitis and pneumonia; b) In treating bronchiolitis, asarone injection was superior to aminophylline, heartleaf houttuynia herb and virazole in total effective rate, and was similar to andrographolide in curative effect; c) In treating COPD and AECOPD, asarone injection was superior to symptomatic treatment and bromhexine in total effective rate, was similar to benzylpenicillin sodium and tablete glycyrrhiza in curative effect, and was inferior to aminophylline in total effective rate without significant difference; d) In treating bronchitis, asarone injection was superior to aminophylline and symptomatic treatment in total effective rate, and was similar to mucosolvin in curative effect; and e) In treating pneumonia, asarone injection was superior to antibiotic, ribavirin and aminophylline in total effective rate. Conclusion Asarone injection is effective in treating respiratory disease. Because of the lower methodological quality and publication bias of the included trials, it is necessary to perform more high-quality and large-scale randomized controlled trials to make the conclusion more reliable.
目的 评价国内干扰素（INF）治疗多发性骨髓瘤（MM）的疗效与安全性。 方法 计算机检索中国期刊全文数据库（1989年－2011年）、中国生物医学文献数据库（1989年-2011年）和中文科技期刊全文数据库（1989年－2011年），并手工检索所有纳入文献的参考文献，纳入INF治疗MM的随机对照试验（RCT）。评价纳入研究的方法学质量并进行资料提取后，采用RevMan 5.0软件进行Meta分析。 结果 共纳入10个RCT，包括366例患者。Meta分析显示，INF联合美法仑+泼尼松（MP） 方案与单用MP方案比较，其总有效率差异有统计学意义[OR=4.52，95% CI（1.84，11.10），P=0.001]；INF联合长春新碱+多柔比星+地塞米松/泼尼松[VAD（P）]与单用VAD（P）方案比较，其总有效率[OR=4.13，95% CI（1.53，11.14），P=0.005]和完全缓解率[OR=3.88，95% CI （1.49，10.16），P=0.006]差异也均有统计学意义；INF+其他化疗方案与单用化疗方案比较，其总有效率[OR=2.57，95%CI（1.11，5.96），P=0.03]和完全缓解率[OR=3.17，95% CI（1.21，8.27），P=0.02]，差异均有统计学意义。 结论 目前国内研究结果表明，INF与化疗联合运用能增加MM治疗的总有效率和缓解率，但由于纳入研究样本量小且质量较低，上述结论尚需要高质量、大样本的随机与双盲对照试验加以分析。
【摘要】 目的 观察腹腔镜手术联合孕三烯酮治疗子宫内膜异位症合并不孕的疗效及不同评分系统对妊娠结局的预测价值。 方法 回顾性分析2004年1月-2006年12月收治的97例子宫内膜异位症合并不孕患者的临床病理资料，统计其术后妊娠率及活产率。 结果 术后1年内与1~2年的妊娠率与活产率比较，差异均无统计学意义（Pgt;0.05）。根据美国生育协会1985年修订的子宫内膜异位症分期标准（r-AFS）进行分期，各期患者术后妊娠率差异无统计学意义（Pgt;0.05）；但随着分期升高，活产率逐渐下降（Plt;0.05）。子宫内膜异位症生育指数（EFI）评分越高，其妊娠率和活产率也越高（Plt;0.05）。 结论 子宫内膜异位症患者腹腔镜手术后联用孕三烯酮可能会提高远期妊娠率。r-AFS分期对妊娠结局的预测有一定局限性，而EFI具有较好的预测性。【Abstract】 Objective To evaluate the therapeutic effectiveness of laparoscopic surgery combined with gestrinone treatment in the infertile women with endometriosis (EM), and the value of different score systems to predict gestational outcome. Methods We retrospectively analyzed the clinical data of 97 infertile women with EM who were treated in our hospital from January 2004 to December 2006, and collected their pregnancy rate (PR) and live birth rate (LBR) after operation. Results There was no significant difference of PR and LBR within the 1st year and between the 1st and the 2nd year (Pgt;0.05). There was no significant difference of PR among women of various stages of EM based on the 1985 edition of risk stratification for patients with EM put forward by American Fertility Society (r-AFS) (Pgt;0.05), but the LBR decreased with the raising of the stages (Plt;0.05). The endometriosis fertility index (EFI) was positively correlated with PR and LBR (Plt;0.05). Conclusion Laparoscopic surgery combined with gestrinone may increase the long-term pregnancy rate of women with EM. R-AFS classification is limited in predicting the gestational outcome of women with EM, while EFI achieves a better result.
The growing rate of public health problem for increasing number of people afflicted with poor sleep quality suggests the importance of developing portable sleep electroencephalogram (EEG) monitoring systems. The system could record the overnight EEG signal, classify sleep stages automatically, and grade the sleep quality. We in our laboratory collected the signals in an easy way using a single channel with three electrodes which were placed in frontal position in case of the electrode drop-off during sleep. For a test, either silver disc electrodes or disposable medical electrocardiographic electrodes were used. Sleep EEG recorded by the two types of electrodes was compared to each other so as to find out which type was more suitable. Two algorithms were used for sleep EEG processing, i.e. amplitude-integrated EEG (aEEG) algorithm and sample entropy algorithm. Results showed that both algorithms could perform sleep stage classification and quality evaluation automatically. The present designed system could be used to monitor overnight sleep and provide quantitative evaluation.
ObjectiveTo systematically review the risk factors in elderly patients with primary hypertension with morning blood pressure surge in China, so asto provide references for clinical treatment and prevention of complications. MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2013), CNKI, VIP and WanFang Data were electronically searched for the case-control studies about morning blood pressure surge (MBPS) among elderly patients with primary hypertension in China from January 2006 to June 2014 were collected. Literature was screened according to inclusion and exclusion criteria, data were extracted and the methodological quality of the included studies was assessed, and then meta-analysis was conducted using RevMan 5.2 software. ResultsA total of 16 studies involving 2 007 cases were finally included, of which 956 cases were detected with MBPS. The results of meta-analysis showed that significant differences were found in glucose levels (MD=0.42, 95%CI 0.04 to 0.81, P=0.03), urinary microalbumin levels (MD=23.85, 95%CI 6.64 to 41.07, P=0.007), incidences of cerebrovascular events (OR=1.96, 95%CI 1.25 to 3.08, P=0.004), carotid atherosclerosis (OR=5.13, 95%CI 1.70 to 15.45, P=0.004) and left ventricular hypertrophy (OR=2.49, 95%CI 1.70 to 3.64, P < 0.000 01), left ventricular mass (MD=12.89, 95%CI 3.94 to 21.84, P=0.005), and carotid artery intima-media thickness (MD=0.08, 95%CI 0.02 to 0.14, P=0.009); while no significant difference was found in gender (OR=1.12, 95%CI 0.84 to 1.49, P=0.44), total cholesterol levels (MD=0.01, 95%CI-0.11 to 0.12, P=0.92), and creatinine levels (MD=1.77, 95%CI-1.16 to 4.70, P=0.24) between patients with or without MBPS. ConclusionCurrent evidence shows that glucose levels, early kidney damage, emergent cerebrovascular events and the reconstruction of the artery and the left ventricle are risk factors of abnormal MBPS in China. However, the above conclusion needs to be verified by further conducting high quality prospective studies.
