Objective To evaluate the prevalence of depression and anxiety in the middle and elderly patients with chest pain from department of emergency.Methods Totally 1200 patients suffering from chest pain were enrolled from July 2009 to August 2009.All patients were scored by self-rating depression scale (SDS) and self evaluation anxious scale (SAS).Results 383 cases of 912 patients(42.0％) with coronary heart disease (CAD) and 58 of 288 patients (20.1％) without CAD had depression,with a statistically significant difference (x2 =44.98,P=0.002).Odds ratio (OR) for CAD in patients with depression was 2.5,with 95 ％ confidence interval (CI) of 1.0-5.0 (P ＜0.05).Conclusions There is high prevalence of depression and anxiety as independent risk factors for CAD.

0.05,X 2 =0.45),and the focus stability ratio were42.5%and32.4%respectively.Compared with the FOLFOX4group,the hospitalization course in capecitabine group is significantly shorter(8.5days vs25.3days,P=0.000)and the total medical cost was significantly lower(5941.7RMB vs13304.6RMB,P=0.001).The cost structure analysis showed that the direct and indirect medical costs of the FOLFOX4group increased more significantly(P=0.001)and the incidence for adverse effects of this group was lower than that of the capecitabine group.CONCLUSION:From the perspective of pharmacoeconomic evaluation,capecitabine is better than FOLFOX4in treating the digestive malignant tumor.

Objective To explore the feasibility of delineation of the atherosclerotic plaque in carotid artery using compressed sensing three dimensional motion-sensitized driven equilibrium prepared rapid gradient echo (CS-3D MERGE) technique. Methods Twenty-three patients who underwent carotid endarterectomy (CEA) were enrolled prospectively. In all patients, bilateral carotid arteries were scanned by CS-3D MERGE and contrast-enhanced MR angiography (MRA) simultaneously. Image quality of CS-3D MERGE images was scored. Images from the CS-3D MERGE sequence and contrast-enhanced MRA were used to measure the carotid stenosis, which were divided into four groups:normal group, mild stenosis group, moderate stenosis group, and severe stenosis group. The results were compared between the two methods. And images from the CS-3D MERGE sequence were compared with corresponding histology in identifying major plaque components including lipid rich necrotic core (LRNC), intraplaque hemorrhage (IPH), and calcification (CA). Spearman rank correlation coefficient was used to compare the correlation between the CS-3D MERGE sequence and contrast-enhanced MRA in measuring the carotid stenosis. Agreement was tested comparing images from the CS-3D MERGE sequence with corresponding histology in identifying major plaque components including lipid-rich necrotic core, intraplaque hemorrhage, and calcification. Results Twenty-three CEA patients finished bilateral CS-3D MERGE scanning successfully. Image quality was 3.16±0.25. There was an excellent correlation between CS-3D MERGE and MRA in measuring stenosis (r=0.95, P<0.01). The agreement between CS-3D MERGE and histological results for LRNC detection was 76.2% (16/21). It was less sensitive for IPH detection (71.4%, 15/21). CS-3D MERGE identified all CA accurately (100.0%, 21/21). Sensitivity and specificity were 86.6% (13/15) and 50.0% (3/6) for LRNC, 73.3% (11/15) and 66.6% (4/6) for IPH, 100.0% for CA respectively(16/16, 5/5). Conclusion CS-3D MERGE, a single sequence, can be used to quantify carotid stenosis and plaque components conveniently.

Objective To investigate the value of contrast enhancement T1 mapping in detection of diffuse myocardial fibrosis in cardiomyopathy, and the relationship between myocardial fibrosis and cardiac function. Methods From September 2013 to September 2014, 76 cases of cardiomyopathy patients (including myocarditis) and 33 cases of healthy controls were enrolled in our study. All the subjects underwent cardiac MR (CMR) examination. Scan sequences included cine MR, pre-contrast and post-contrast T1 mapping and late gadolinium enhancement (LGE) imaging. The pre-/post-contrast left ventricle average T1 value and cardiac function of patients and controls were measured and compared by using independent-samples t test. According to the LGE imaging, all the subjects were subsequently divided into LGE positive group, LGE negative group and control group. The myocardial average T1 value and cardiac function among the three sub-groups were compared by using one-way ANOVA, and the relationship among them were analyzed by using Pearson correlation. Results Among the 76 cases of non-ischemia cardiomyopathy patients, 51 cases (67.1%) had LGE. Compared with controls, cardiomyopathy patients presented with higher pre-contrast T1 value [(1 306.4 ± 84.6)ms vs. (1 266.6 ± 57.3)ms, t=2.10, P<0.05] and lower post-contrast T1 value [(483.6 ± 112.0)ms vs. (534.1 ± 92.7)ms,t=-0.27, P<0.05]. Pre-contrast and post-contrast average T1 value of LGE positive patients were (1 322.2 ± 85.8) and (459.7 ± 132.2)ms respectively;pre-contrast and post-contrast average T1 value of LGE negative patients were (1 267.0 ± 68.5) ms and (521.0±95.2)ms, there were statistical significant differences of T1 value between LGE positive and LGE negative patients (P<0.01), however, there were no statistical significant differences of T1 value between LGE negative patients and controls (P>0.05). There were correlation between pre-/post-contrast left ventricle T1 value and ejection fraction (EF) in cardiomyopathy patients (r=-0.252,-0.217, P<0.01), however no statistical correlation with other cardiac function parameters (P>0.05). Conclusions The average pre-/post-contrast T1 value in left ventricle myocardium are helpful for detection of diffuse fibrosis in cardiomyopathy patients. The LGE positive is a sign that can greatly change the T1 value of the myocardial tissue, meanwhile, myocardial fibrosis is negative correlated with ejection fraction in cardiomyopathy patients.

Objectives To assess the plasma levels of acyl ghrelin (AG) and dys-acyl ghrelin (DG) in chronic kidney disease (CKD) and hemodialysis (HD) patients and analyze their relationships with different stages of CKD and hemodialysis. Methods Forty-six CKD stage 1-5 patients and 15 hemodialysis patients were enrolled into the study. Body weight, height, hemoglobin, biochemical parameters, inflammatory parameters, preprandial, postprandial and 3 hours after hemodialysis plasma AG and DG levels were measured. Appetite and food intake were assessed. Body mass index (BMI), and estimated glomerular filtration rate (eGFR) were calculated. Results There were no significant differences in BMI, SGA, appetite, food intake and malnutrition among CKD patients of different stages. eGFR was declining with the progression of CKD stages and patients received a three-week hemodi-alysis. Compared with that in CKD stage 1-2 patients, the level of preprandial and postprandial DG was remarkably increased in stage 3-5 patients (P<0.01). The level of DG was significantly decreased after a standard breakfast in CKD patients (P<0.01). CKD stage was positively correlated with preprandial (r=0.31, P<0.05)a nd postprandi-al DG (r=0.34, P < 0.05), TNF-α (r=0.33, P < 0.05), IL-6 (r=0.40, P < 0.05), leptin (r=0.34, P < 0.05), and age (r=0.41, P<0.05). CKD stage was also highly and positively correlated with the proportion of preprandial and postprandial DG (r=0.61, P<0.01;r=0.55, P<0.01). Multivariate partial-correlation analysis showed that CKD was independently associated with the proportion of preprandial and postprandial DG (r=0.55, P < 0.01; r=0.43, P < 0.01).There was no decrease in AG postprandially, nor any changes in AG resultant from dialysis (P > 0.05);levels of DG decreased slightly postprandially and were markedly decreased by hemodialysis (P<0.01), even lower than those seen postprandially in CKD stage 1-2;Both preprandial and postprandial DG were negatively correlated with serum albumin levels (r=-0.64, P < 0.05; r=-0.59, P < 0.05), while there was no correlation between AG and serum albumin levels. Conclusions There is a strong and independent correlation of DG with CKD stage. Postprandial suppression of ghrelin is impaired with reduced renal function. Hemodialysis removes DG but not AG.

Objective To investigate the diagnostic performance of stress cardiac magnetic resonance(CMR) for evaluating low-risk patients with suspected acute coronary syndrome(ACS).Methods Twenty-two patients with low risk of suspected ACS were prospectively and consecutively enrolled in this study.Diagnostic performance of stress CMR was compared with single-photon emission computed tomography(SPECT) for diagnosis of myocardial ischemia with coronary angiography (CAG) as the reference method.Results On the patient-based level analysis,the diagnostic performance of CMR for detection of ACS was sensitivity 93% and specificity 75%.The corresponding value of SPECT was 79%,63%.The area under the ROC (AUC) of CMR was 0.897, which was slightly superior to that of SPECT at 0.723 (P=0.19).On the per-vessel assessment, the diagnostic value of CMR was sensitivity 89%,specificity 87%, while the corresponding value of SPECT was 68%,83%.The AUC of CMR was 0.923,which was significantly higher than that of SPECT at 0.774 (P<0.05).Furthermore, the AUC of CMR was significantly superior to that of SPECT with AUC being 0.900 and 0.553 in the left anterior descending (LAD) vessels (P=0.009 6).Conclusion Stress perfusion CMR has excellent diagnostic performance in low risk ACS patients.Compared with SPECT,stress perfusion CMR performed better in the low-risk ACS populations.

Objective To evaluate the lung V/Q imaging in the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH).Methods Seventy-six patients (46 males,30 females,age 27-84 y) with clinically suspected CTEPH who had undergone lung V/Q imaging,CT pulmonary angiography (CTPA),pulmonary angiography (PA) and right heart cardiac catheterization were studied.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of lung V/Q imaging in detecting CTEPH were calculated and compared with those of CTPA.The x2 test was used for statistical analysis with SPSS 11.5.The distribution of involvement of segments in 47 patients with CTEPH was analyzed.Results Forty-seven patients had a final diagnosis of CTEPH and 29 had non-CTEPH etiology.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of lung V/Q imaging were 97.9％ (46/47),86.2％ (25/29),93.4％ (71/76),92.0％ (46/50) and 96.2％ (25/26),while those of CTPA were 78.7％ (37/47),93.1％ (27/29),84.2％ (64/76),94.9％ (37/39) and 73.0％ (27/37),respectively.The sensitivity (x2 =5.818,P=0.012) and negative predictive value (x2 =5.693,P =0.017) for lung V/Q imaging were significantly higher than those of CTPA.V/Q imaging could identify patients with CTEPH from those with idiopathic PAH and familial PAH based on the almost normal ventilation imaging.The lung perfusion SPECT imaging detected 585 (62.2％) of involved segments among 940 segments in 47 patients with CTEPH,with an average of 12.4 involved segments in each patient.The number of involved segments in the right lung was significantly higher than that in the left lung (36.2％ (340/940) vs 26.1％ (245/940) ; x2 =40.85,P＜0.01).Conclusions Lung V/Q imaging plays an important role in diagnosis of CTEPH and in identification of CTEPH from other types of PAH.A normal V/Q imaging can effectively exclude CTEPH.In addition,V/Q imaging can provide more diagnostic information in patients with a clinical suspicion of CTEPH who had negative results by CTPA and PA.

OBJECTIVE: To evaluate the effect of the vestibular diagnosis and treatment system (SRM-IV ) in diagnosis and treatment of patients with benign paroxysmal positional vertigo (BPPV). METHOD: Patients who were diagnosed as BPPV by SRM-TV in the clinic of our hospital from November 2013 to October 2014 were retrospectively analyzed in this study. RESULT: Among 425 suspected cases, 230 BPPV-positive patients were diagnosed including 131 cases of posterior SC (57.0%), 95 cases of horizontal SC (41.3%) and 4 cases of more than two SC (1.7%). The cure rate by SRM-V was 94.6% and the effective rate was 100.0%. The relapsed occurred in 10 patients (4.8%), which contained 4 men and 6 women. CONCLUSION SRM-V can realize 360° reasonable repositioning procedure while Canalish reposition procedure cannot. SRM-V can improve both the corrective rate of diagnosis and the cure rate, especially for the patients who suffered from complex BPPV.

Objective To observe the difference among the patients with chronic fatigue syndrome (CFS), mild-to-moderate depression or anxiety disorders in symptoms of fatigue, depression and anxiety. Methods Fatigue Scale-14 (FS-14), Hamilton Rating Scale for Depression (HAMD) and Hamilton Rating Scale for Anxiety (HAMA) were used to evaluate 182 cases with CFS, mild-to-moderate depression or anxiety disorders. Results There was no significant difference in physical fatigue, mental fatigue and comprehensive fatigue among 3 groups (P>0.05). There were 39 (62.9%) CFS patients perhaps with depression symptoms and 23 (37.1%) patients with mild-to-moderate depression symptoms. There were 46 (74.2%) CFS patients perhaps with anxiety symptoms and 16 (25.8%) patients with mild-to-moderate anxiety symptoms. The score of HAMD was significant lower in the CFS group than in the mild-to-moderate depression disorder group (P<0.001). There were significant differences in the anxiety/somatization and hysteresis (P<0.01), as well as in cognitive disturbance, diurnal variation and hopelessness (P<0.05) between the CFS group and mild-to-moderate depression disorder group. The scores of HAMA was significant lower in the CFS group than in the mild-to- moderate anxiety disorder group (P<0.001). There was significant difference in mental-anxiety (P<0.01), as well as in body-anxiety (P<0.05) between the CFS group and the mild-to-moderate anxiety disorder group. Conclusion The symptoms of emotion disorders and fatigue symptoms were both presented in patients with CFS, mild-to-moderate depression and anxiety disorders. They share common clinical features.
