Background and Objective:Diffuse large B-cell lymphoma (DLBCL), the most common type of non-Hodgkin's lymphoma (NHL), is heterogeneous on molecular and clinical levels, therefore, its prognosis is difficult to *** study aimed to evaluate the value of Blimp-1 protein and Hans classification in predicting the prognosis of DLBCL and their ***:The clinical records of 136 patients with DLBCL were *** patients were followed up for 5-80 months (median, 39 months).Immunohistochemical staining for CD10, MUM1, Bcl-6, and Blimp-1 were performed on paraffin-embedded tumor tissues from the 136 *** correlations of Blimp-1 protein and Hans classification in prognosis of DLBCL and their interrelation were ***:Blimp-1 was detected in 38 (30.0%) patients, and was associated with a significantly shorter overall survival (OS) (P=0.030).Using the Hans classification based upon the expression of CD10, Bcl-6, and MUM1, 54 patients had germinal center B-cell (GCB) phenotype and 82 had non-GCB *** 5-year OS rate was 75% in the GCB group and 52% in the non-GCB group (P=0.020).The positive rate of Blimp-1 was 22.2% in the GCB group and 31.7% in the non-GCB group (P=0.329).The Cox regression multivariate analysis showed that international prognosis index (IPI) and Hans classification had independent prognostic significance, whereas Blimp-1 was not an independent prognostic ***:The patients with GCB subtype of DLBCL had better prognosis than the non-GCB *** level of Blimp-1 expression in the patients with DLBCL implies a shorter survival, but it is not associated with Hans classification.

中子辐射俘获反应在反应堆运行、核装置设计及核天体物理研究中起重要的作用.4πBaF_(2)探测装置有着高时间分辨能力、低中子灵敏度、高探测效率等优点,适合开展中子辐射俘获反应截面数据的测量.中国原子能科学研究院核数据重点实验室建立了伽马全吸收装置(Gamma total absorption facility,GTAF),该装置用28块六棱BaF_(2)晶体和12块五棱BaF_(2)晶体构成了外径25 cm,内径10 cm的球壳,覆盖了95.2%的立体角.利用GTAF在中国散裂中子源Back-n束线上,测量了197Au(n,γ)的反应截面数据.测量数据通过能量筛选、PSD方法、晶体多重性筛选进行了初步本底扣除,随后结合对^(nat)C及空样品的测量数据对本底进行了分析及扣除,获得了197Au俘获反应的产额,利用SAMMY程序拟合得到了^(197)Au在1—100 e V的共振能量、中子共振宽度和伽马共振宽度参数.实验测量结果与ENDF/B-VIII.0数据库符合良好,其共振参数存在一定差异,分析原因可能与GTAF能量分辨率、Back-n的中子能谱测量精度、以及实验本底扣除方法相关,这也是下一步工作的重点.

Chinese Medical Sciences Journal 2012年第4期27卷 195-200页

作者： Lu lin Yi-ning Wang ling-yan Kong Zheng-yu Jin Guang-ming Lu Zhao-qi zhang Jian cao Shuo li Lan song zhi-wei Wang Kang Zhou Ming Wang Department of Radiology Peking Union Medical College Hospital Chinese Academy of Medical Sciences & Peking Union Medical College Department of Radiology Nanjing General Hospital of Nanjing Military Command Department of Radiology Anzhen Hospital Affiliated to the Capital Medicine of University

Objective To evaluate the image quality （IQ） and radiation dose of 128-slice dual-source computed tomography （DSCT） coronary angiography using prospectively electrocardiogram （ECG）-triggered sequen- tial scan mode compared with ECG-gated spiral scan mode in a population with atrial fibrillation. Methods Thirty-two patients with suspected coronary artery disease and permanent atrial fibrilla- tion referred for a second-generation 128-slice DSCT coronary angiography were included in the prospec- tive study. Of them, 17 patients （sequential group） were randomly selected to use a prospectively ECG.~triggered sequential scan, while the other 15 patients （spiral group） used a retrospectively ECG-gated spiral scan. The IQ was assessed by two readers independently, using a four-point grading scale from excel- lent （grade 1） to non-assessable （grade 4）, based on the American Heart Association 15-segment model. IQ of each segment and effective dose of each natient were comDared between the two groups. Results The mean heart rate （HR） of the sequential group was 96±27 beats per minute （bpm） with a variation range of 73±25 bpm, while the mean HR of the spiral group was 86±22 bpm with a variationrange of 65±24 bpm. Both of the mean FIR （t= 1.91, P=0.243） and HR variation range （t=0.950, P=0.350） had no significant difference between the two groups. In per-segment analysis, IQ of the sequential group vs. spiral group was rated as excellent （grade 1） in 190/244 （78%） vs. 177/217 （82%） by readerl and 197/245 （80%） vs. 174/214 （81%） by reader2, as non-assessable （grade 4） in 4/244 （2%） vs. 2/217 （1%） by readerl and 6/245 （2%） vs. 4/214 （2%） by reader2. Overall averaged IQ per-patient in the sequential and spiral group showed equally good （1.27＋0.19 vs. 1.25＋0.22, Z=-0.834, P=0.404）. The effective radiation dose of the sequential group reduced significantly compared with the spiral group （4.88±1.77 mSv vs. 10.20±3.64 mSv; t=-5.372, P=0.000）. Conclusion Compared with retrospectively E

The Chinese-German Journal of Clinical Oncology 2009年第10期8卷 585-591页

Objective： We evaluated the value of using a panel of GC B-cell （CD10 and Bcl-6） and activation （MUM1, CD138 and Bcl-2） markers by immunohistochemistry to define prognosis in patients with diffuse large B-cell lymphoma （DLBCL）. Methods： Two different models （Hans＇ and modified Chang＇s model） were applied on 136 de hove DLBCL patients. Median follow-up in all patients was 39 months （range 5-80 months）. Results： According to Hans＇ model, patients with GCB had much better overall survival （5-year OS, 75%） than those with non-GCB （5-year OS, 52%）（Kaplan-Meier survival analysis, P 〈 0.05, log rank test）. According to modified Chang＇s model, patients with group 1 had much better overall survival （5-year OS, 78%） than those with group 3 （5-year OS, 44%） while group 2 had no significant value compared with group 1 and group 3 in prognosis （Kaplan-Meier survival analysis, P 〈 0.05, log-rank test）. Using multivariate Cox proportional hazards regression analysis, the international prognostic index scores （IPI）, expression of CD138 and the expression pattern of modified Chang＇s model were independent prognostic indicators. Conclusion： Our results suggest that the expression patterns of the panel of GCB-cell and activation markers by immunohistochemistry correlate with prognosis of patients with DLBCL and both models can be used well in ordinary work.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.
