目的探讨血清总三碘甲状腺原氨酸(TT_(3))水平与维持性血液透析(MHD)患者合并左心室肥厚(LVH)的关系。方法根据是否合并LVH,将602例MHD患者分为LVH组(260例)和对照组(342例),比较两组甲状腺功能和生化指标,采用多因素logistic回归分析MHD患者合并LVH的影响因素,采用ROC曲线分析相关指标对MHD患者合并LVH的预测价值。结果LVH组年龄高于对照组,透析龄低于对照组(P<0.05)。LVH组血清TT_(3)、白蛋白、前白蛋白和尿素清除指数(Kt/V)低于对照组(P<0.05),LDL、血磷、CRP和N末端脑钠肽前体高于对照组(P<0.05)。LVH组低T3综合征发生率高于对照组(P<0.01)。高龄和高水平CRP是MHD患者合并LVH的独立危险因素(P<0.05),高水平TT_(3)、白蛋白、前白蛋白和Kt/V是MHD患者合并LVH的保护性因素(P<0.05)。血清TT_(3)预测MHD患者合并LVH的AUC为0.893(P<0.01)。取TT_(3)0.74 nmol/L为最佳诊断界值时,其预测MHD患者合并LVH的灵敏度为73.8%,特异度为90.9%。结论血清TT_(3)水平与MHD患者合并LVH密切相关,对其有较高的预测价值。

采用界面聚合的方法制备了带正负两种电荷的新型复合纳滤膜。先将氯甲基化聚砜/聚砜共混膜季铵化得到正电荷的基膜,再通过2,5-二胺基苯磺酸(DIA)和均苯三甲酰氯(TMC)的界面聚合反应得到荷负电的复合层,从而制备了QAPSF/PSF/DIA复合纳滤膜。实验测定了基膜和复合膜对单盐、PEG1000和PEG1000+NaCl混合系统的通量和截留情况,实验结果表明,复合膜对PEG1000的截留率达到86%,对盐的截留率不高,在0%~35%之间。还研究该复合膜对染料+盐系统的应用情况。实验结果表明QAPSF/PSF/DIA复合膜对活性翠蓝截留率达到100%,对二甲酚橙截留率达到96%,对染料截留率随染料分子量增大而增大。

We report the first results on 76Ge neutrinoless double beta decay from stage one of the China dark-matter experiment （CDEX）. A p-type point-contact high-purity germanium detector with a mass of 994g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304kgd has been analyzed over a wide spectral band from 500keV to 3MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039MeV energy range. The half-life of76Ge neutrinoless double beta decay derived based on this result is 70v2〉6.4× 1022 yr （90%C.L.）. An upper limit on the effective Majorana-neutrino mass of 5.0eV has been achieved.

The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper.

The velocity and direction of internal waves(IWs) are important parameters of the ocean,however,traditional observation methods can only obtain the average parameters of IWs for a single location or large ***,a new method based on optical flow is proposed to derive the phase velocity vectors of IWs from X-band marine radar ***,the X-band marine radar image sequence is averaged,and ramp correction is used to reduce the attenuation of gray values with increasing radial ***,the average propagation direction of the IWs is determined using the two-dimensional Fourier transform of the radar images;two radial profiles along this direction are selected from two adjacent radar images;and then,the average phase velocity of the IWs is estimated from these radial ***,the averaged radar images are processed via histogram equalization and binarization to reduce the influence of noise on the radar ***,a weighting factor is determined using the average phase velocity of a reference point;the phase velocities on the wave crest of the IWs are subsequently estimated via the optical flow ***,the proposed method is validated using X-band marine radar image sequences observed on an oil platform in the South China Sea,and the error of the phase velocity is calculated to be 0.000 3–0.073 8 m/*** application conditions of the proposed method are also discussed using two different types of IW packets.
