A novel and simple chemical reaction method was developed to synthesize dendrite-like La（OH）3 nanostructures which was composed of centripetal arranged La（OH）3 nanorods with diameters of 50-100 nm and lengths of several micrometers. The effect of different alkaline sources on the morphology of La（OH）3 nanostructures was investigated. It is indicated that diethyl- enetriamine acts not only as an alkaline source, but also as a surfactant which induces the centripetal growth of La（OH）3 nanostructures. Moreover, dendrite-like La203 nanostructures were prepared by the calcination of La（OH）3 nanostructures at 750 ℃. The morphology, structure, and composition of the as-synthesized products were characterized by transmission electron microscopy （SEM）, high-resolution transmission electron microscopy, field emission scanning electron microscopy （FESEM）, and X-ray powder diffraction （XRD）.

Objective To review the applications of magnetic resonance imaging （MRI） techniques in assessing treatment response to gamma knife radiosurgery for brain tumors. Data sources Published articles about assessing treatment response to gamma knife radiosurgery for brain tumors were selected using PubMed. The search terms were ＂MRr＇, ＂gamma knife＂ and ＂brain tumors＂. Study selection Articles regarding the MRI techniques using for early assessment of treatment response of gamma knife were selected. Results MRI techniques, especially diffusion weighted imaging, perfusion weighted imaging, magnetic resonance spectroscopy, are useful for early assessment of treatment response of gamma knife by detecting the hemodynamic, metabolic, and cellular alterations. Moreover, they can also provide important information on prognosis. Conclusions Diffusion weighted imaging, perfusion weighted imaging and magnetic resonance spectroscopy can provide early assessment of treatment response of gamma knife for brain tumors, and also information of tumor progression or recurrence earlier than conventional MRI. But there are still many questions to be answered which should be based on the development and advancement of MRI and related disciplines.

To quantitatively evaluate the time-delay （TD） signatures of chaotic signals generated by vertical-cavity surface- emitting lasers （VCSELs） with polarization-rotated optical feedback （PROF）, we propose four cases of resolution coefficients R based on correlation functions. The resolution coefficient characteristics for the x-polarization （XP） mode, g-polarization （YP） mode and the total output are considered. The dependences of R on the feedback strength and feedback delay are discussed and compared carefully. The two-dimensional maps of R show that the TD signatures for the single polarization mode （i.e., XP or YP mode） are much more difficult to retrieve than those for the total output in the entire parameter space. Thus, by using single polarization mode as a chaotic carrier, the TD signatures are extremely difficult to be identified, which contributes a lot in the security-enhanced VCSELs-based chaotic optical communication systems.

目的阐明肥厚型梗阻性心肌病(HCM)患者术后左心室质量指数(LVMI)的变化与与室间隔心肌切除术的相关性,进一步确定LVMI预测室间隔心肌切除术后转归的价值。方法回顾性纳入2012年9月至2019年12月中国医学科学院阜外医院完成术前及术后左右1年行心脏核磁检查的HCM患者89例,研究室间隔心肌切除术术前和切除术后的左心室质量(LVM)差与手术切除心肌重量的线性相关性,并进行中远期随访,应用Cox比例风险模型构建术后复合不良心血管事件发生的预测模型,并应用Kaplan-Meier生存分析比较不同LVMI组间的室间隔心肌切除术后中远期转归结果。结果术后LVM较术前显著性下降[(187.9±115.3)g比(153.6.9±99.3)g,P<0.001]。手术前后LVM差值为26.7(3.7,61.5)g,术中切除心肌重量平均为(11.0±5.1)g,两者比较具有统计学差异(P<0.001)。设定术中切除心肌重量为自变量,手术前后LVM差值为因变量,二元线性回归分析统计结果表明,手术前后LVM差值与术中切除心肌重量呈线性相关性(P=0.0112,R=0.268,R2=0.072)。9例(10.1%)患者在平均(43.4.6±20.5)个月的随访期间发生不良复合事件。在Cox比例风险回归模型中,室间隔心肌切除术后最显著的预测因子是CMR测量的LVMI(风险比1.025,95%CI 1.009~1.040,P=0.002)。在接受者操作特征曲线(ROC)分析中,LVMI≥95.1 g/m2可准确预测不良复合事件发生(敏感度77.8%;特异度77.5%;曲线下面积AUC=0.748,P=0.0109)。Kaplan-Meier生存曲线图提示,HCM患者LVMI增高组室间隔心肌切除术后中远期不良复合事件发生率高(P<0.001)。结论心肌切除术后左心室心肌质量消退明显大于术中切除心肌重量,室间隔心肌切除术利于梗阻性HCM患者的左心室逆向重构。术前较高的LVMI是HCM患者心肌切除术后中远期不良事件的独立预测因子。

Background： Several studies have reported that apolipoprotein A5 （APOA5） is involved in the development of non-alcoholic fatty liver disease （NAFLD）. However, no research has been performed regardingthe association between APOA5 polymorphisms and the risk of NAFLD. This study aimed to explore theassociation between APOA5 gene polymorphisms and NAFLD in a Chinese Han population.
