Objective To compare the efficacy and safety of thrombolysis and anticoagulant therapy for post-traumatic acute submassive pulmonary embolism (PE) in middle-aged and elderly patients.Methods Totally 45 patients with post-traumatic acute submassive pulmonary embolism in our hospital were selected.Patients were divided into thrombolysis group (n =22) and anticoagulation group (n=23) according to their conditions.Symptoms and signs,blood gas analysis,D-dimer,echocardiography,CT pulmonary angiography (CTPA) were performed before and after thrombolysis or anticoagulant therapy.Results There were no significant differences in clinical curative rate between thrombolysis group and anticoagulation group [95.5％ (21/22) vs.91.3％ (21/23),x2 =0.32,P＞0.05],and no case was found dead in both two groups.There was a significant difference in hemorrhage rate between thrombolysis group and anticoagulation group [27.3％ vs.4.3％,x2 =4.53,P ＜ 0.05].At 24 hours after thrombolysis or anticoagulant therapy,the improvement rate of dyspnea,PaO2 level was significantly higher and the pulmonary arterial pressure was significantly lower in thrombolysis group than in anticoagulation group [45.5％ (10/22) vs.17.4％ (4/23),(80.4±8.1) mm Hg vs.(73.6±9.3) mm Hg,(51.2±6.2) mm Hgvs.(60.3±5.7) mm Hg,respectively,all P＜0.05],and there were no statistical significances at other time points between the two groups.Conclusions The clinical curative rate and fatality rate are similar in thrombolysis group versus anticoagulation group.Hemorrhage rate is higher in thrombolysis group than in anticoagulation group.Thrombolysis can relieve dyspnea rapidly,reduce pulmonary artery pressure and make the embolized blood vessels recanalized.Patients with low bleeding risk in a critical condition are suggested to take thrombolysis therapy,while patients with high bleeding risk in a light condition are suggested to take anticoagulant therapy.

Objective: To compile and evaluate the Chinese version of perioperative nursing quality assessment scale, detect and verify the reliability and validity of evaluation scale, and establish a scientiifc evaluation system. Methods: We applied Tuija Leinonene and Helena Leino-kilpi scales as the theoretical framework, and established perioperative nursing quality assessment scale by translation, language study, and expert consultation. hTe questionnaire survey population was 276 patients who had surgery and 200 nurses working in the operating rooms at the 3 Affliated Hospitals of Central South University. hTe scale was tested validity and reliability. Results: Perioperative nurse quality evaluation scale consisted of 32 items and 7 dimensions, including body care, receive information, support, respect, medical staff characteristics, environment and nursing process. The test-retest reliability of scale was 0.977 for patients and 0.997 for nurses. hTe split half reliability of scale was 0.761 for patients and 0.887 for nurses. hTe Cronbach's α of total scale for the patients was 0.918, and the Cronbach's α of factors was 0.658-0.838. hTe Cronbach's α of total scale for the nurses was 0.932, and the Cronbach's α of factors was 0.650-0.836. hTe correlation coeffcient of scale for the patients was 0.363-0.603; the factors and the total correlation coeffcient was 0.535-0.788. hTe correlation coeffcient of scale for the nurses was 0.410-0.700; the factors and the total correlation coeffcient was 0.743-0.902. Conclusion: The Chinese version of the perioperative nursing quality assessment scale is a measurement instrument with a high level of validity and reliability for Chinese society and can be used to determine the quality of perioperative nursing care in our country.

Objective To evaluate whether three chronic kidney disease epidemiology collaboration (CKD-EPI) equations (CKD-EPI2009Scr,CKD-EPI2012SCysC and CKD-EPI2012Scr-SCysC) are applicable in the prediction of glomerular filtration rate (GFR) in Chinese patients with diabetic nephropathy (DN).Methods One hundred and eight patients with DN who were hospitalized in the First Affiliated Hospital of Guangzhou Medical University with GFR being measured by dynamic renal imaging with 99mTc-DTPA from June 2012 to April 2014 were enrolled in this study.GFR measured by dynamic renal imaging with 99mTe-DTPA was used as the reference value (rGFR).GFR was estimated by the CKD-EPI2009Scr equation,the CKD-EPI2012SCySC equation,and the CKD-EPI2012Scr-SCysC equation (labeled as eGFR1,eGFR2,eGFR3).The correlation,30％ accuracy,staging consistency,deviation and diagnostic accuracy were compared among the three CKD-EPI equations.Results The rGFR in 108 DN patients was (61.78±26.51) ml· min-1· (1.73 m2)-1.The correlation between three eGFRs and rGFR was significant (all P ＜ 0.01),the correlation coefficients were 0.738,0.708,0.782.The 30％ accuracy were 74.07％,52.78％,67.59％,The 30％ accuracy of eGFR1 and eGFR3 were higher than eGFR2 (all P ＜ 0.05),but there was no significant difference between eGFR3 and eGFR1 (x2=0.874,P=0.436).The staging consistency was not ideal,Kappa values were 0.391,0.180 and 0.422.For the deviations between three eGFRs and rGFR,there was no significant difference between eGFR3 and rGFR (P ＞ 0.05),eGFR1 underestimated rGFR,eGFR2 overestimated rGFR (all P ＜ 0.01).The results of the Bland-Altman chart showed that consistencies between three eGFRs and rGFR were poor,the degree of deviation of eGFR3 was the smallest.The area under the ROC curve (AUC) of three eGFRs was 0.878,0.883 and 0.915.The AUC,sensitivity,specificity,overall compliance rate and Youden index of eGFR3 were the highest.Conclusions The eGFRs predicted by the three CKD-EPI equations showed good relevance,accuracy and diagnostic accuracy with the rGFR,but poor in consistencies.Comparatively,CKD-EPI2012Scr-SCysC may be better than others,but its consistency limits exceeds the acceptable limits.Therefore,the applicability of using the three CKD-EPI equations to predict the GFR in Chinese DN patients requires a larger sample and multiple verifications as well as further improvement.

Objective To investigate the screening significance of transcranial Doppler (TCD) for patients with patent foramen ovale ( PFO) induced cerebral embolism and to improve the treatment aiming at the causes.Methods Thirty-six patients of less than 60 years old with unknown-cause cerebral embolism and transient ischemic attack were enrolled.Besides conventional examination,the 24 h Holter,transthoracic echocariiography,carotid artery Doppler ultrasonography (CAU),routine TCD,TCD foaming test,transesophageal echocardiography (TEE),CT angiography (CTA) of head and neck,ultrasonography of vein in bilateral lower limbs were examined in all patients.Results All the patients showed no atrial fibrillation.No structural heart disease and intracardiac occupying lesion were shown in transthoracic echocardiography.No carotid stenosis was shown in carotid artery Doppler ultrasonography.Routine TCD showed no intracranial artery stenosis.No thrombus was found in ultrasonography of deep veins in bilateral lower limbs.CTA of head and neck showed everything was normal.Fourteen patients were observed with right-to-left shunt in heart by TCD foaming test,including 10 cases with microbubble signals(MBS) in 10 s,and 4 cases with MBS after Valsalva maneuver.Among 14 patients,12 patients were proved PFO by TEE.Conclusions PFO is one of the causes of cardiogenic cerebral embolism.TCD is accurate and reliable for the screening of PFO.

Objective To evaluate the diagnostic accuracy of half-Fourier single-shot TSE MR cholangiopancreatography (HASTE-MRCP) of 0.5 T MR scanner, and to assess its imaging advantage and clinical value by comparing with 3D-TSE-MRCP MIP. Methods All 95 patients were examined by HASTE-MRCP and 3D-TSE-MRCP with respiratory-triggering (Philips 0.5 T T5-NT). The results, including anatomies and diseases, were evaluated after operation. Results By HASTE-MRCP, common bile ducts, 1-3 branches of hepatic ducts, gallbladder, and pancreatic ducts were demonstrated in 100.0%, 94.7%, 74.1%, and 63.2% of the cases. Stones, malignant diseases, and postoperative stenosis were revealed in 100.0% of the cases. Compared with 3D-TSE-MRCP, the demonstrating rates of 4-5 hepatic ducts,neck of the gallbladders,and calculi,especially mud calculi, were higher in HASTE-MRCP, and there was significant difference between the two ways. Stones displayed as low signal in the bile ducts. Block obstruction and mass contour were revealed in malignant diseases. Conclusion Comparing with 3D TSE-MRCP, HASTE-MRCP was better and faster, especially in serious patients or in cases with small and mud calculus.
