Objective:To observe the influence of post-operative early enteral nutrition(EEN) for oral tumour patients.Methods:Sixty patients with oral tumour were randomly divided into EEN group (30 cases) and tradition enteral nutrition(TEN) group (30 cases). The nutritional support with Nutrision fiber started within the first 12~16 h post-operatively in EEN group, The enteral feeding started within the recovery time of the gut function in TEN group. Nutritional parameters were measured before and after the operation. Results:The mean hospitalization days in EEN group and TEN group were 10.14?1.58 and 15.29?3.26 respectively(P

Objective To study time-dependent degradation of DNA in lymphocytes in the human bloodstain in order to estimate aging of bloodstain.Methods Lymphocytes were isolated from the human bloodstain placed under room temperature and were analyzed by single-cell gel electrophoresis(SCGE).The percentage of DNA-degraded lymphocytes were calculated in the cloodstain placed at different time intervals from 0 to 72h under fluorescent microscope connected with auto-analysis-image system.Results The percentage of DNA degraded lymphocytes was closely correlated with time lapse within 72h.A regression equation was formulated with R=0.9522(P

Objective To explore the value of energy spectrum CT in the diagnosis of breast cancer.Methods Thirty-two hospitalized patients whose American Colledge of Radiology (ACR) breast imaging reporting and data system (BI-RADS) scores were 4-5 by mammography received non-enhanced spectral CT scans.The spectrum images,spectrum curve,lesion's size,morphology were observed,and also the pectoralis major muscle and axillary lymph node metastasis were evaluated and compared with mammography.Results Thirty-two patients were confirmed by pathology,including 16 cases of invasive duct carcinomas,1 case of medullary carcinoma,15 cases of lobular carcinomas,and 11 cases of the pectoralis major muscle invaded,9 cases of the axillary lymph nodes metastasis.ACR BI-RADS scores 4 were 23 cases,5 were 9 cases.Axillary lymph node metastasis and primary tumor spectrum curves were basically the same.Energy spectrum CT showed the lesion's shape,size,the relationship with the pectoralis major muscle and axillary lymph node metastasis.In 40-70 keV spectrum curve breast cancer displayed a downward trend.There were no significant differences between energy spectrum CT and mammography for the lesion's shape,edge,internal calcification and thickening of adjacent skin (P ＞ 0.05).While energy spectrum CT exhibited obvious advantages in demonstrating the pectoralis major muscle invaded and axillary lymph node metastasis (P ＜ 0.05).Conclusion Energy spectrum CT imaging displays greater clinical value for diagnosing breast cancer,and it can provide multi-parameter image for supporting clinical practice.

Objective To conduct a Meta analysis based evaluation of dual-source computed tomography (DSCT) in the diagnosis of coronary artery disease (CAD). Methods Literatures publicated from January 2006 to July 2009, including in English or Chinese languages, were searched in Medline,China National Knowledge Infrastructure (CNKI), and Chinese Medical Assosiation Digital Periodicals (CMADP). A study was enrolled if it: ( 1 ) used DSCT angiography as the diagnostic test for the detection of significant coronary stenosis ( ≥50% diameter stenosis) in patients with suspected CAD; (2) used coronary angiography as the reference standard. The pooled sensitivity and specificity of the 95% confidence interval (95% CI) were acquired based on the bivariate random-effects modol. Hierarchical weighted symmetric summary receiver-operating curve (HSROC) was also estimated. The pooled likelihood ratios were calculated based on the pooled sensitivity and specificity. Combined with the pooled likelihood ratios, the clinical utility of the results was estimated according to Bayes'theory. Results Total of ten articles enrolled in this study, included 1271 patients. The mean rate of nonevaluable patients and segments were 5.6% (33/590) and 2. 3% (271/11 745 ), respectively. The pooled statistical results were as follows: the sensitivity and specificity were 99% (97%-99% ) and 86% (79%-90% ), respectively; the positive and negative likelihood ratio were 6. 84 and 0. 01, respectively. If a pre-test probability was below 84%, the likelihood of disease was less than 5% on a negative diagnosis of DSCT. If a pre-test probability was above 13%, the likelihood of disease was more than 50% on a positive diagnosis of DSCT. Conclusions DSCT angiography presents good diagnostic performance in the detection of CAD; however, it could not completely replace conventional coronary angiography.
