Methods Literatures in CBM, CNKI, VIP, WanFang databases were searched from the time of establishment of these databases till July 2010. Randomized controlled trials (RCT) of budesonide versus dexamethasone for the treatment of acute laryngitis in children were gathered, and quality was evaluated and meta-analysis was carried out. Results Eleven RCTs were identified, and meta-analysis indicated that there were significant differences between the two groups in the disappearing time of hoarseness, barking cough, dyspnea and laryngeal stridor. The MD values and their 95% CI were respectively -0.88 (-1.10, -0.65), -1.43 (-2.01, -0.84), -0.48 (-0.63, -0.32), and -0.59 (-0.78, -0.41). Conclusion Based on current evidence in China, budesonide is better than dexamethasone for the improvement of acute laryngitis in children.
ObjectivesTo systematically review the efficacy and safety of controlled hypotension for total hip or knee replacement.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on controlled hypotension for total hip or knee replacement from inception to September 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 15 RCTs involving 854 patients were included. The results of meta-analysis showed that compared with no controlled hypotension during surgery, controlled hypotension could reduce intraoperative blood loss (MD=−267.35, 95%CI −314.54 to −220.16, P<0.000 01), allogeneic blood transfusion (MD=−292.84, 95%CI −384.95 to −200.73, P<0.000 01), and 24 h postoperative mini-mental state examination (MMSE) score (MD=−1.08, 95%CI −1.82 to −0.34, P=0.004). However, there were no significant differences in 96 h postoperative MMSE score (MD=−0.11, 95%CI −0.50 to 0.28, P= 0.57) and intraoperative urine volume (MD=57.93, 95%CI −152.57 to 268.44, P=0.59).ConclusionsThe current evidence shows that controlled hypotension during total hip or knee replacement can reduce intraoperative blood loss and allogeneic blood transfusion. Furthermore, there is no obvious effect on the maintenance of blood perfusion in important organs, despite certain effects on the postoperative cognitive function, which can be recovered in short term. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
【摘要】 目的 评估对于曾有急性心肌梗死的室性心动过速(VT)患者,导管消融(RA)减少植入式心脏转复除颤器(ICD)放电转律治疗的疗效和安全性。 方法 计算机检索Pubmed、EMbase、Cochrane图书馆、中国生物医学文献光盘数据库、中文科技期刊全文数据库、CNKI数字图书馆,纳入RA+ICD和单独使用ICD对比治疗VT患者的随机对照临床试验,对纳入的研究进行质量评价和Meta分析。 结果 共纳入2篇最近发表在国外一流杂志上面的临床随机对照研究,一篇发在《新英格兰杂志》,另外一篇发在《柳叶刀》。RA+ICD组纳入116例患者,其中有23例(20%)因为再发VT或者心室颤动(Vf)而进行了ICD放电转律治疗;ICD组纳入119例患者,其中有49例(41%)因为再发VT或者Vf而进行了ICD放电转律治疗。Meta分析结果显示,RA+ICD的组合相对于单独运用ICD来说,需要进行ICD放电转律治疗的人数较少,OR=0.33,95%CI(0.18~0.61),P=0.000 4。 结论 目前研究认为射频消融可能可减少需进行ICD放电转律治疗的人数,以后需要更多更大样本量的研究进一步证实该结果。【Abstract】 Objective To assess the efficacy and safety of radiofrequency catheter ablation (RA) for the prevention of defibrillator therapy with implantable cardioverter defibrillator (ICD) for patients who have had acute myocardial infarction with ventricular tachycardia (VT). Methods Randomized controlled trials on patients with VT who underwent RA and ICD versus ICD alone were searched from Pubmed, EMbase, the Cochrane Central register of controlled trials, China Biology Medicine database, Chinese Science and Technology Journal database and the CNKI digital library. Quality assessment and Meta analysis were carried out for the researches sought out from these databases. Results Two randomized controlled studies published on The New England Journal of Medicine and the Lancet were included in our study. RA plus ICD were used in 116 cases, among whom 23 underwent ICD shocks due to reoccurrence of VT or ventricular fibrillation (Vf). Single ICD was used in 119 cases among whom 49 underwent ICD shocks due to reoccurrence of VT or Vf The result of Meta analysis showed that the number of patients needing ICD shocks after RA plus ICD treatment was significantly lower than that after single ICD treatment. The statistical data of the comprehensive Meta analysis were OR=0.33, 95%CI (0.18-0.61), and P=0.000 4. Conclusion At present, it is believed that RA can be used for the prevention of defibrillator therapy, while the result should be confirmed by large sample research in the future.
ObjectiveTo systematically review the risk factors associated with sleep disorders in ICU patients.MethodsWe searched The Cochrane Library, PubMed, EMbase, Web of Science, CNKI, Wanfang Data, VIP and CBM databases to collect cohort studies, case-control studies and cross-sectional studies on the risk factors associated with sleep disorders in ICU patients from inception to October, 2018. Two reviewers independently screened literature, extracted data and evaluated the bias risk of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 9 articles were included, with a total of 1 068 patients, including 12 risk factors. The results of meta-analysis showed that the combined effect of equipment noise (OR=0.42, 95%CI 0.26 to 0.68, P=0.000 4), patients’ talk (OR=0.53, 95%CI 0.42 to 0.66, P<0.000 01), patients’ noise (OR=0.39, 95%CI 0.21 to 0.74, P=0.004), light (OR=0.29, 95%CI 0.18 to 0.45, P<0.000 01), night treatment (OR=0.36, 95%CI 0.26 to 0.50, P<0.000 01), diseases and drug effects (OR=0.17,95%CI 0.08 to 0.36, P<0.000 01), pain (OR=0.37, 95%CI 0.17 to 0.82, P=0.01), comfort changes (OR=0.34,95%CI 0.17 to 0.67,P=0.002), anxiety (OR=0.31,95%CI 0.12 to 0.78, P=0.01), visit time (OR=0.72, 95%CI 0.53 to 0.98, P=0.04), economic burden (OR=0.63, 95%CI 0.48 to 0.82, P=0.000 5) were statistically significant risk factors for sleep disorders in ICU patients.ConclusionCurrent evidence shows that the risk factors for sleep disorders in ICU patients are environmental factors (talking voices of nurses, patient noise, and light), treatment factors (night treatment), disease factors (disease itself and drug effects, pain,) and psychological factors (visiting time, economic burden). Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusions.
Objective To determine the affected factors of intraorbital hemodynamic results in diabetic retinopathy (DR) and the risk factors related to the occurrence of DR. Methods Posterior ciliary artery (PCA), central retinal artery (CRA), central retinal vein (CRV), and vortex vein (VV) of 68 patients with DR were measured by color Doppler flow image (CDFI). Thirty-one hemodynamic parameters, including systolic velocity, diastolic velocity, mean velocity, resistive index, pulsatility index and accelerative velocity of ophthalmic artery (OA), and other variates (blood pressure, blood sugar, gender, age, duration of the disease, and so on) were collected and clustered in a principal components analys is following a forward, stepwise logistic regression on these components. Results Nine principal components were extracted from 37 original variates, reflecting the velocity of OA, velocity of PCA, resistance of OA, velocity of CRA,resistance of CRA, resistance of PCA, time-related factor, venous drainage factor and gender factor, respectively. In the result of logistic regression, resistance of OA, velocity of CRA, resistance of PCA, time-related factor, and venous drainage factor were the risk factors related to DR. Conclusion The first risk factor affecting DR is time, and intraorbital hemodynamic abnormity influencing the development of diabetic retinopathy may be the increase of resistance of OA, decrease of velocity of CRA, decrease of resistance of PCA, and increase of venous drainage.

Objective To systematically evaluate the clinical effectiveness of platelet-rich plasma (PRP) combined with grafting material for the treatment of periodontal intrabony defects. Methods The following databases such as PubMed, The Cochrane Library, EMbase, CNKI, CBM and WanFang Data were searched on computer from inception to August, 2012 to collect the relevant randomized controlled trials (RCTs) on PRP combined with grafting material versus grafting material alone for periodontal intrabony defects. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality of the included studies. RevMan 5.2 software was applied for meta-analysis. Results A total of 11 RCTs involving 342 patients were included. The pooled analysis on 7 RCTs showed that there was a significant difference in lower increase of clinical attachment loss (WMD=0.70, 95%CI 0.51 to 0.90, Plt;0.000 01) between the PRP combined with grafting material group and the grafting material alone group. But there was no significant difference in the gingival recession (WMD= −0.01, 95%CI −0.15 to 0.13, P=0.86). The pooled analysis on 9 RCTs showed that there was no significant difference in the reduction of plaque index (WMD= −0.04, 95%CI −0.09 to 0.02, P=0.20) between the two groups. Conclusion PRP combined with grafting material is superior to grafting material alone in the clinical attachment loss. But, there are no significant differences in gingival recession and plaque index. However, given the limited sample size and incomplete measure indexes of included studies, this conclusion still needs to be further proved by conducting more high-quality and large-scale RCTs.
Objective To evaluate the short-term clinical efficacy and safety of 10-Hydroxy-camptothecin (10- HCPT ) chemotherapy on gastrointestinal carcinoma. Methods We searched electronic database including CNKI ( 1995 - 2005 ), MEDLINE ( 1995 - 2005 ) and The Cochrane Library ( Issue 1, 2005 ). More related research data were odtained by cantacting with researchers. Randomized controlled trials of gastrointestinal carcinoma chemotherapy comparing only or including 10-HCPT chemotherapy with normal chemotherapy on efficacy rate, digestive and hematology system toxicity were included. Data related to the clinical outcome were extracted by two reviewers independently. Statistical analysis was performed by using RevMan4. 2.2. Results Twenty-five trials including 1 881 patients met the inclusion criteria. The results of meta-analysis were hsted as follows: 10-HCPT could significantly improve the short-term chemotherapy efficacy for colorectal cancer ( RR. 1.62, 95% CI 1.37 to 1.92) and gastric cancer (RR 1.48, 95% CI 1.18 to 1.85)in chemotherapy curative efficacy in short-term. 10-HCPT induced severe toxicity of lower digestive system(RR. 0.96,95% CI 0.62 to 1.50 ) without statistical significance, while severe toxicity of hematology system was significantly higher than that of control with RR 1.27,95% CI 1.02 to 1.58. Conclusions Current evidence suggests that 10-HCPT can improve hematology system short-term chemotherapy efficacy for gastrointestinal carcinoma and increase the incidence of severe toxicity. Further research is needed to value its influence on the prognosis of gastrointestinal carcinoma.
Objective To systematically review the efficacy and safety of laparoscopic hepatectomy (LH) and open hepatectomy (OH) for patients with hepatocellular carcinoma (HCC). Methods PubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI databases were electronically searched to collect the case-control studies about LH vs. OH for patients with HCC from inception to December, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software. Results A total of 28 studies involving 1 908 patients were included. The results of meta-analysis showed that: the LH group was superior to OH group on complications (OR=0.35, 95%CI 0.26 to 0.48, P<0.000 01), hospital stay (MD=–4.18, 95%CI (–5.08, –3.29),P<0.000 01), and five years overall survival rate (OR=1.65, 95%CI 1.23 to 2.19,P=0.000 7) and disease-free survival rate (OR=1.51, 95%CI 1.12 to 2.03, P=0.006). However, no significant differences were found in one year and three years overall survival rate, disease-free survival rate, and postoperative recurrence rate. Conclusion Current evidence shows that the LH is superior to OH for the treatment of HCC, and may be amenable to surgery because of its safety and longtime efficacy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
