Objective To investigate the value of high-dose dobutamine stress echocardiography combined with two-dimensional strain imaging in early diagnosis of coronary artery disease. Methods Highdose dobutamine stress echocardiography was performed to 28 patients with suspected coronary artery disease. All wall movements were observed during resting condition and at all stress levels,respectively;the peak systolic longitudinal strain in each endomyocardial segment of left ventricular was measured; the sensitivity and specificity between visual method and two-dimensional strain imaging in diagnosing myocardial ischemia with high-dose dobutamine stress echocardiography were compared. The average peak systolic longitudinal strain was calculated against control group, coronary artery disease group during ischemia segments and non-ischemia segments, and a comparison was made inside each group as well as against the other groups. The area under receiver operating characteristic curve of the peak systolic longitudinal strain was used to predict the sensitivity and the specificity of myocardial ischemia. Results With dobutamine dose of 40 μg·kg-1 · min-1 ,wall motion abnormalities were diagnosed in 6 patients (20 segments) through visual method, myocardial ischemia was found in 15 patients (148 segments) through computing the peak systolic longitudinal strain. Inside the coronary artery disease group during ischemic　segments,the majority of peak systolic longitudinal strain was significantly reduced ( P＜0.05) compared to the non-ischemic segments and the control group. In diagnosing myocardial ischemia in high-dose dobutamine stress echocardiography, the sensitivity of visual method and two-dimensional strain imaging were 35.3％ and 88.2％(P＜0.01), specificity 100％ and 100％(P＞0.05), and accuracy 60.7％ and 92.8％ (P＜0.01). The cutoff value of the peak systolic longitudinal strain was less than or equal to 14.9％, its sensitivity and specificity in predicting myocardial ischemia were 83.3％ and 91.7％,respectively. Conclusions High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can increase the sensitivity of detecting myocardial ischemia and detect concealed myocardial ischemia. High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can be used in early diagnosis of coronary artery disease.

OBJECTIVEEpidemiologic study on the perinatal interaction of antioxidant vitamins and heavy metals on offspring's intellectual development is extremely limited. The aim of this prospective cohort study was to investigate the status of maternal and cord blood antioxidant vitamins (Vitamin A, E and C) and heavy metals (lead, cadmium and mercury) at delivery and correlations between these antioxidant vitamins or metals and neurodevelopment of early childhood, and to explore the protective effect of antioxidant vitamins against the injure of heavy metals to intellectual development in children in Tongliang, Chongqing, China.

METHODA total of 150 pairs of mothers-neonates were recruited. Serum concentrations of vitamin(V) A, vitamin E, vitamin C, lead, cadmium and mercury in maternal and cord blood after delivery were determined and intellectual development was evaluated by Gesell Development Schedule (GDS) at two years of age.

RESULTA total of 111 pairs of maternal-neonatal subjects with completed data were included into statistical analysis. After adjusting for potential confounders, cord blood mercury level was found negatively associated with all the development quotients (DQs) (β = -0.486, β = -0.716, β = -0.846, β = -0.935, β = -0.702, P < 0.05). Cord VE level was positively correlated with motor, adaptation, language and average DQ (β = 0.475, β = 0.458, β = 0.403, β = 0.395, P < 0.05). When antioxidant vitamins and heavy metals levels were all included into the multiple regression model, cord vitamin E level was statistically positively related with motor, adaptation and average DQs (β = 0.449, β = 0.412, β = 0.349, P < 0.05). While cord blood mercury level was negatively correlated with adaptation, language, social and average DQ (β = -0.397, β = -0.727, β = -0.935, β = -0.628, P < 0.05), the relationship between cord mercury level and motor DQ was not statistically significant (P = 0.0890). The motor, adaptation, language and average DQs in high cord VE group were higher than those in low VE group (t = 2.93, t = 2.06, t = 2.13, t = 2.27, P < 0.05). Social DQ in high cord lead group was significantly lower than that in low lead group (χ(2) = 5.56, P = 0.015). Cord VC level in high cadmium group was significantly lower than that in low cadmium group (χ(2) = 7.62, P = 0.006). VA placental transport ratio in high mercury group was significantly lower than those in low mercury group (χ(2) = 8.02, P = 0.005).

CONCLUSIONOur data suggested that there may be certain interaction between antioxidant vitamin A, E, C and heavy metals lead, cadmium, mercury. Antioxidant vitamins at delivery may have protective effect on the early neurodevelopment via interaction with the heavy metals.

Brain magnetic resonance imaging (MRI) of the elderly often reveals white matter changes (WMCs) with substantial variability across individuals.Our study was designed to explore MRI features and site-specific factors of ischemic WMCs.Clinical data of consecutive patients diagnosed with ischemic cerebral vascular disease who had undergone brain MRI were collected and analyzed.Multi-logistic regression analysis comparing patients with mild versus severe WMCs was performed to detect independent associations.Analyses of variance (ANOVAs) were used to detect regionally specific differences in lesions.We found that lesion distribution differed significantly across five cerebral areas,with lesions being predominant in the frontal lobe and parieto-occipital area.To explore WMCs risk factors,after adjusting for gender,diabetes mellitus,and hypertension,only age (P＜0.01),creatinine (P=0.01),alkaline phosphatase (ALP) (P=0.01) and low-density lipoprotein cholesterol (LDL-C) (P=0.03) were found to be independently associated with severe WMCs.Age (P＜0.001) was strongly associated with WMCs in the frontal lobe while hypertension was independently related to lesions in the basal ganglia (P=0.048) or infratentorial area (P=0.016).In conclusion,MRI of WMCs showed that ischemic WMCs occurred mostly in the frontal lobe and parieto-occipital area.The infratentorial area was least affected by WMCs.Typically,age-related WMCs were observed in the frontal lobes,while hypertension-related WMCs tended to occur in the basal ganglia and infratentorial area.

Objective To analysis performance assessment results of clinical nurses, and to explore the effect of quantitative management on nurse training and culture. Methods Quantitative evaluation was applied in performance assessment of nurses in terms of service quality, technical quality, attendance, skill test, credit,continuing education, professional title, paper publishing, position and duration, recognition and reward,scientific research and quality improvement. Results Professional title was found positively correlated with total score, professional ability and psychological quality. There was significant difference among the groups (P ＜0. 01). Total score of performance assessment, professional ability and psychological quality significantly increased with duration of work (P ＜ 0. 01). Conclusions Performance assessment scores have shown an increasing trend with the application and improvement of the assessment. Quantitative performance evaluation can enhance nurses' service awareness, help to improve the overall quality of nurses, but also provide the basis for the trainning of nurses.

OBJECTIVETo observe the changes in the activity of dendritic cells (DCs) after carcino-embryonic antigen (CEA) gene transfection mediated by recombinant adeno-associated virus type2 (rAAV) and tumor cell lysate.

METHODSImmature DCs isolated from peripheral blood monocytes of HLA-A11-positive healthy volunteers were infected with the rAAV carrying CEA gene or loaded with tumor cell lysate. The surface markers of the DCs such as CD40, CD 1alpha, and CD86 were analyzed by flow cytometry. Interleukin-12 (IL-12) in the supernatants of DCs and interferon-gamma (IFN-gamma) released by the cytotoxic T lymphocytes (CTLs) were determined by ELISA detection kit. The specific killing activity of CTL against LoVo cells was assessed by MTT assay.

RESULTSThe DCs following antigen loading with the two methods both highly expressed CD40, CD86 and IL-12, and induced specific CTL that specifically recognized and killed LoVo cells, but the killing effect resulting from rAAV infection of the DCs was much better than that induced by tumor cell lysate loading.

CONCLUSIONBoth methods of antigen loading can induce mature DCs from peripheral blood monocyte cells, but rAAV infection of the DCs can be more effective than tumor cells lysate loading. DCs infected with rAAV may have the potential to serve as an adjuvant immunotherapy for patients with colorectal carcinoma.

OBJECTIVE: To establish the 2-dimensional electrophoresis(2-DE) profiles of peripheral blood mononuclear cells(PBMC) in patients with hepatocellular carcinoma(HCC) and health adults. METHODS: The total proteins from PBMC in patients with HCC and healthy adult were separated by immobilized pH gradient-based 2-DE. The differential expression proteins were analyzed by PDQuest analysis software. RESULTS: The well-resolved, reproducible 2-DE patterns of PBMC in patients with HCC and healthy adults were obtained. For HCC, the average spots of 2-DE maps were 1 206 +/- 48, and the average matching rate was 90.8%. For normal adults, the average spots were 1 123 +/- 37, and the average matching rate was 92.6%. CONCLUSION The well-resolved, reproducible 2-DE patterns of PBMC in patients with HCC and healthy adults are established. These proteomic analysis methods are useful to screen the potential biomarkers in the early diagnosis, treatment and prognosis monitor in patients with malignant tumor.
