Objective: To evaluate the diagnostic accuracy of contrast-enhanced ultrasonography (CEUS) in differentiating between benign and malignant enlarged lymph nodes using meta-analysis. Materials and Methods: Pubmed, Embase, SCI and Cochrane databases were searched for studies (up to September 1, 2014) reporting the diagnostic performance of CEUS in discriminating between benign and malignant lymph nodes. Inclusion criteria were: prospective study; histopathology as the reference standard; and sufficient data to construct $2{\times}2$ contingency tables. Methodological quality was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Patient clinical characteristics, sensitivity and specificity were extracted. The summary receiver operating characteristic curve was used to examine the accuracy of CEUS. A meta-analysis was performed to evaluate the clinical utility in identification of benign and malignant lymph nodes. Sensitivity analysis was performed after omitting outliers identified in a bivariate boxplot and publication bias was assessed with Egger testing. Results: The pooled sensitivity, specificity and AUROC were 0.92 (95%CI, 0.85-0.96), 0.91 (95%CI, 0.82-0.95) and 0.97 (95%CI, 0.95-0.98), respectively. After omitting 3 outlier studies, heterogeneity decreased. Sensitivity analysis demonstrated no disproportionate influences of individual studies. Publication bias was not significant. Conclusions: CEUS is a promising diagnostic modality in differentiating between benign and malignant lymph nodes and can potentially reduce unnecessary fine-needle aspiration biopsies of benign nodes.

Background: Fatty liver is a growing health issue in China. However, the research concerning the infi uence of economic development on the prevalence of fatty liver was sparse. This study is to investigate the relation between economic status and the adult prevalence of fatty liver in the mainland of China. Methods: Literature searches on PubMed, EMBASE, Web of Science and Chinese National Knowledge Infrastructure databases were performed to identify eligible studies published before July 10, 2014. Gross domestic product (GDP) per capita was chosen to assess the economic status. The correlations were obtained by Pearson coeffi cient. Results: 27 studies, from 22 cities and 2 provinces from 1995 to 2013, were included in this study. In general, the prevalence of fatty liver presented a signifi cant correlation with GDP per capita (r = 0. 459, P = 0. 016). To be specifi c, the prevalence in north China correlated with GDP per capita (r = 0. 879, P = 0. 05) and survey year (r = 0. 909, P = 0. 032). In south China, on the contrary, the prevalence failed to correlate with the two indicators. According to the data from multiple years, the city of Shanghai witnessed an ascending prevalence. In terms of gender, the prevalence of female correlated with GDP per capita (r = 0. 572, P = 0. 004) and survey year (r = 0. 483, P = 0. 020). Meanwhile, there was no correlation between the prevalence of male and GDP per capita (P = 0. 129) or survey year (P = 0. 358). Conclusions: In the mainland of China, higher GDP per capita suggested higher adult prevalence of fatty liver, based on the data in the past 20 years. With the development of economy, public health interventions, thus, are essential to prevent the trend of obesity and alcohol abuse.

This paper presents a smart home system prototype which employs an indoor positioning system called the III Beacon Match (I3BM) positioning method to intelligently trigger the appropriately services for the home members. To overcome the ninja problem in the I3BM method, the signal filtering, adjustment and smooth procedures are proposed. The proposed system prototype employs the Zigbee module to implement the prototypes of the components for the I3BM positioning method, and the prototypes had passed the ZigBee Compliant Platform (ZCP) certification test. The proposed system prototype which intelligently controls the air condition and light system for smart home applications is also verifying in our demo room and in the smart house in National Taiwan University.

Aims and Background: The purpose of the research was to study the prognostic value of tumor 18F-FDG PET-based parameters in neoadjuvant chemoradiation for patients with squamous esophageal carcinoma. Methods: Sixty patients received chemoradiation therapy followed by esophagectomy and two 18FDG-PET examinations at pre- and post-radiation therapy. PET-based metabolic-response parameters were calculated based on histopathologic response. Linear regression correlation and Cox proportional hazards models were used to determine prognostic value of all PET-based parameters with reference to overall survival. Results: Sensitivity (88.2%) and specificity (86.5%) of a percentage decrease of SUVmax were better than other PET-based parameters for prediction of histopathologic response. Only percentage decrease of SUVmax and tumor length correlated with overall survival time (linear regression coefficient ${\beta}$: 0.704 and 0.684, P<0.05). The Cox proportional hazards model indicated higher hazard ratio (HR=0.897, P=0.002) with decrease of SUVmax compared with decrease of tumor size (HR=0.813, P=0.009). Conclusion: Decrease of SUVmax and tumor size are significant prognostic factors in chemoradiation of esophageal carcinoma.
