Background The long-term prognostic influence of left atrial diameter （LAD） remodeling on the status of post-radiofrequency catheter ablation （RI CA） atrial fibrillation （AF） is unclear. This study employed a two-stage model from 3-year echocardiographic data to ascertain whether the two-stage model predicts RFCA outcome more favorably than models using the baseline LAD. Methods Data were retrospectively collected from 263 consecutive patients with drug-refractory AF undergoing RFCA. Regular echocardiographic measurements of LAD were performed at baseline, 1, 3, 6, and 12 months and then every 6 months after RFCA. Sex, age, type of AF, number of RFCA, and AF status were recorded. We obtain the actual （predicted） 3-year LAD using a longitudinal linear mixed model （1st stage）. Logistic regression models based on the baseline LAD （Model 1）, actual （predicted） 3-year LAD （Model 2）（2nd stage）, and observed 3-year LAD （Model 3） were constructed to predict RFCA outcome. The area under the receiver operating characteristic curve （AUC） were used to assess the performance of models. Results The lowess smoothed curve indicated that the LAD declined over the first three months and remained stable up to 36 months after RFCA. The degree of LAD reduction was significantly influenced by the baseline LAD. Non-paroxysmal AF, large LAD and female gender were significant predictors of AF recurrence. Model 2 had the largest AUC among the three models. Conclusions This longitudinal study-based two-stage model outperforms the original logistic model using the baseline LAD. Non-paroxysmal AF, larger LAD and female gender are significant predictors of RFCA failure.

Searching for classical Be stars in LAMOST DR1

作者： Chien-Cheng Lin Jin-Liang Hou Li Chen Zheng-yi Shao Jing Zhong po-Chieh Yu Shanghai Astronomical Observatory Chinese Academy of Sciences Department of Physics and Astronomy University of CaliforniaLos AngelesCA 90024USA

We report on searching for Classical B-type emission-line（CBe） stars in the first data release of the Large Sky Area Multi-Object fiber Spectroscopic Telescope（LAMOST; also called the Guo Shou Jing Telescope）. A total of 192 objects（including 12 previously known CBes） were identified as CBe candidates with prominent He I λ4387, He I λ4471 and Mg II λ4481 absorption lines, as well as Hβλ4861and Hαλ6563 emission lines. These candidates significantly increase the currently known sample of CBes by about 8%. Most of the CBe candidates are distributed near the Galactic Anti-Center due to the observing strategy used for LAMOST. Only two CBes are in star clusters. These two CBes have ages of 15.8 and 398 Myr, respectively.

Immobilization of Escherichia coli for detection of phage T4 using surface plasmon resonance

Phage contamination is a very serious and unavoidable problem in modem fermentation industry. It is necessary to develop sensitive and rapid phage detection methods for the early detection of phage contamination. In the present work, a real-time, rapid, specific and quantitative phage T4 detection method based on surface plasmon resonance （SPR） technique has been in- troduced. Escherichia coli was immobilized onto the preformed MPA self-assembled monolayer （SAM） through the widely used EDC/NHS cross-linking reaction as the recognition element. The bacteria immobilization was verified efficiently through the electrochemical measurements and fluorescence microscopy observations. The specific adsorption was much stronger than the non-specific adsorption of phage T4 binding to the biosensor surface modified by E. coli, and the latter could be neglected. The detection sensitivity reached 1×10^7 PFU/mL within 10 min. Within the experimental phage concentrations, the linear cor- relation between the SPR response and the phage concentration was good. The results suggest that the SPR technique is a po- tentially powerful tool for the phage or other virus detections, as a label-free, real-time, and rapid method.
