Objective To evaluate the intervention effectiveness of collaboration among physicians, nurses and pharmacists for elderly people. Methods Randomized controlled trails ( RCT) of collaboration among physicians,nurses and pharmacists for elderly people were gathered from MEDLINE,EMbase,CENTRAL,CNKI,VIP and Wanfang. The retrieved studies were screened according to the inclusion and exclusion criteria, evaluated the quality of included studies, and then performed meta-analyses with The Cochrane Collaboration ' s Revman 5. 3. 0 software. Results Four randomized controlled trials of collaboration among physicians,nurses and pharmacists for elderly people were included. The results of meta-analyses showed that the hospitalization rate, emergency admission rate, mortality and potentially inappropriate medication use were not significantly better in the collaboration group than in the standard of care group [RR=1.02,95%CI (0.93,1.11),P=0.69;RR=0.97,95%CI (0.89,1.05),P=0.42;RR=1.03,95%CI (0.87,1.21),P=0.75;and RR=1.09,95%CI (0.84,1.41),P=0.51,respectively]. There were no statistically significant differences between the collaboration group and the standard of care group. Conclusion Collaboration among physicians, nurses and pharmacists is not therapeutically effective for elderly people. But its long-term efficacy still needs to be confirmed by performing more high quality,large sample RCTs with long term follow-up.

Objective To explore the association between circulating endothelial cells (CECs)and atherosclerosis in maintenance hemodialysis(MHD)patients. Methods A crosssectional study was performed to investigate the association between CECs and carotid atherosclerotic change in 65 MHD patients,25 non-hemodialysis patients with chronic kidney disease(CKD)of stage 4 or 5(CKD-non-HD)and 24 age-and Sex-matched healthy controls. CECs in peripheral blood were determined by multiparametrie flow cytometry(FCM).CECs were labeled with CD3-PerCP and CD146-PE before FCM and identified as CD3dim,CD146bright.Atherosclerosis in both groups Was assessed by the measurement of common carotid arery intimamedia thickness (CCA-IMT)and plaque of the common carotid arteries with ultrasound scanner. Results CECs were significantly higher in pre-dialysis patients[(151.52±98.24) cell/ml]and CKD-non-HD patients[(183.00±81.38)cell/ml ] compared with control group[(106.50± 24.14)cell/ml](P<0.05 and P<0.01,respectively).But the number of CECs was not significantly different between MHD and CKD-non-HD patients.CCA-IMT was also significantly higher in MHD patients[(0.94±0.36)mm]and CKD-non-HD patients [(1.02±0.37)mml compared with control group[(0.75±0.15)mm](P<0.05 and P<0.01,respectively).The number of pre-dialysis CECs was positively correlated with CCA-IMT in MHD patients(r=0.328,P<0.01).Multivariate analysis showed that CEC level was a strong independent risk factor of CCA-IMT. Conclusion InMHD patients, CEC level is associated with carotid atherosclerosis and may be used as a marker to evaluate the endothelial damage.

Objective:To evaluate the effectiveness and safety of butyl phthalide capsules combined with Xueshuantong injection in the treatment of acute cerebral infarction (ACI). Methods: Cochrane Library, Medline, Embase, SCI, CBM, CNKI, VIP and Wanfang databases were searched from the building time to May 2016. The enrolled randomized controlled trails were studied by using Cochrane system evaluation methods to perform methodological quality assessment, and RevMan 5. 2 software was used to carry out Me-ta-analysis. Results:A total of 7 randomized controlled trails including 640 patients were enrolled. The results of Meta-analysis dem-onstrated that the effective rate of butylphthalide capsules combined with Xueshuantong injection was superior to that of Xueshuantong injection (RR=1. 33, 95%CI:1. 16-1. 52, P<0. 0001), butylphthalide (RR=1. 45, 95%CI:1. 15-1. 83, P=0. 002) and blank control (RR=1. 31, 95%CI:1. 08-1. 57, P=0. 005). NHISS of butylphthalide capsules combined with Xueshuantong injection was higher than that of Xueshuantong injection (MD=4. 63, 95%CI:3. 38-5. 87, P<0. 00001) and blank control (MD=6. 85, 95%CI:4. 90-8. 80, P<0. 00001). There was no significant difference in adverse drug reactions. Conclusion: Butylphthalide capsules combined with Xueshuantong injection is effective for the therapy of ACI. However, due to the limited quantity and quality of the in-cluded studies, larger scale trials are needed.

Objective: To evaluate the diagnostic value of BRAF V600E mutation combined with shear wave elastography(SWE) for thyroid nodules of Bethesda Ⅲ diagnosed by fine-neddle aspiration(FNAC). Methods: One hundred and seventeen thyroid nodules diagnosed as Bethesda Ⅲ in the department of ultrasound and confirmed by BRAF V600E gene detection, SWE examination and surgery were collected. BRAF V600E detection, SWE examination and both combined with pathological results were using to retrospective analysis. Results: There were 75 benign nodules and 42 malignant nodules according to pathology. Sensitivity and negative predictive value of BRAF V600E combined with SWE were higher than single BRAF V600E mutation detection and SWE with statistically significant(P=0.01, 0.001; P=0.029, 0.01, respectively). There were no statistically differences between single BRAF V600E mutation detection and SWE for Bethesda Ⅲ nodules(P=0.483, 0.645). Conclusions BRAF V600E mutation detection combined with SWE can improve the sensitivity and negative predictive value in the diagnosis of Bethesda Ⅲ thyroid nodules.

Objective:To establish a predictive risk model for acute kidney injury (AKI) in acute myocardial infarction (AMI) patients based on machine learning algorithm and compare with a traditional logistic regression model.Methods:It was a retrospective study. The demographic data, laboratory examination, treatment regimen and medication of AMI patients from July 2011 to December 2016 in Beijing Anzhen Hospital, Capital Medical University were collected. The diagnostic criteria of AKI were based on the AKI diagnosis and treatment guidelines published by Kidney Diseases: Improving Global Outcomes in 2012. The selected AMI patients were randomly divided into training set (70%) and internal test set (30%) by simple random sampling. SelectFromModel and Lasso regression models were used to extract clinical parameters as predictors of AKI in AMI patients. Logistic regression model (model A) and machine learning algorithm (model B) were used to establish the risk prediction model of AKI in AMI patients. DeLong method was used to compare the area under the receiver-operating characteristic (ROC) curve ( AUC) between model A and model B for selecting the best model. Results:A total of 6 014 AMI patients were included in the study, with age of (58.4±11.7) years old and 3 414 males (80.5%). There were 674 patients (11.2%) with AKI. There were 4 252 patients (70.7%) in the training set and 1 762 patients (29.3%) in the test set. The selected twelve clinical parameters by the SelectFromModel and Lasso regression models included the number of myocardial infarctions, ST-segment elevation myocardial infarction, ventricular tachycardia, third degree atrioventricular block, decompensated heart failure at admission, admission serum creatinine, admission blood urea nitrogen, admission peak creatine kinase isoenzyme, diuretics, maximum daily dose of diuretics, days of diuretic use and statins. Logistic regression prediction model showed that AUC for the test set was 0.80 (95% CI 0.76-0.84). The machine learning algorithm model obtained AUC in the test set with 0.82 (95% CI 0.78-0.85).There was no significant difference in AUC between the two models ( Z=0.858, P=0.363), and AUC of the machine learning algorithm predictive model was slightly higher than that of the traditional logistic regression model. Conclusions:The prediction effect of AKI risk in AMI patients based on machine learning algorithm is similar to that of traditional logistic regression model, and the prediction accuracy of machine learning algorithm is better. The introduction of machine learning algorithm model may improve the ability to predict AKI risk.
