In the market of botanical dietary supplements, Cimicifuga heracleifolia(CH) has always been considered as an adulterated species of Cimicifuga racemosa(CR), a conventional American herb with promising benefits to counteract troubles arising from the menopause. However, the detailed comparison of their therapeutic effects is lacking. In present study, the pharmacological and metabolomics studies were comparatively conducted between CH and CR in ovariectomized(OVX) female rats. Specifically, estrogen-like, anti-hyperlipidemia and anti-osteoporosis effects were evaluated through measuring serum biochemical parameters, histopathological examination and micro computed tomography(Micro-CT) scanning. At the same time, a gas chromatography-mass spectrometry(GC-MS)-based serum metabolomics method was employed to profile the metabolite compositional changes. As a result, both CR and CH displayed anti-osteoporosis and anti-hyperlipemia on menopause syndrome. Meanwhile, their potentials in improving the OVX-induced metabolic disorders were discovered. In conclusion, these results demonstrated that CH is therapeutically similar to CR in relieving menopausal symptoms and CH could be considered as a promising alternative to CR instead of an adulterant in the market of botanical dietary supplements.

首次详细描述了河南省石门沟、阳坡和山西省水峪等3条剖面寒武系底部辛集组中的遗迹化石。遗迹化石主要产出于辛集组的近底部层位,以水平管状遗迹化石为主,共计8遗迹属,12遗迹种(含3个未定种),包括Arenicolites sp.,Didymaulichnus lyelli,Gordia marina,Helminthopsis abeli,Helminthopsis sp.,Palaeophycus striatus,Palaeophycus tubularis,Phycodes sp.,Planolites beverleyensis,Planolites montanus,Treptichnus pedum与Treptichnus pollardi,此外还有2枚属种未定的遗迹化石。这一遗迹化石组合属非典型的Cruziana遗迹相,形成于盐度正常的潮下带砂质软底环境。通过对寒武纪早期管状遗迹化石Palaeophycus与Planolites直径大小的统计与分析,推测辛集组下部地层的时代不早于沧浪铺期。

Natural biological microtubular networks have undergone adaptive evolutionary selection and may offer viable solutions to design challenges in artificial microtubular networks. The plasmodium of the slime mold Physarum polycephalum(P. polycephalum) extends continuously to form a protoplasmic microtubular network structure, directly connecting food *** simulations revealed that the formation of this adaptive P. polycephalum microtubular network could be captured by a mathematical algorithm. Inspired by the P. polycephalum microtubular networks, we propose an adaptive optimization design method for artificial microtubular networks. Specifically, we utilized hydrogels with biodegradable and tissue-adhesive properties to replicate the P. polycephalum microtubular networks via photomask. In Rhodamine B diffusion and glucosecatalyzed reaction experiments, we found that the P. polycephalum microtubular networks exhibited significantly enhanced efficiency compared to vascular and artificial networks. Furthermore, we demonstrated the potential for uric acid(UA) degradation of the hydrogels with a real P. polycephalum microtubular network loaded with urate oxidase(UOx) in a rodent model of hyperuricemia. And this network achieved more than double the effect of the artificial network. This underscores the potential of natural microtubular networks to replace artificial microtubular networks.

祁连造山带内发育有多套富铁沉积地层和具有经济开采价值的铁矿,包括肃南著名的镜铁山铁矿和肃北石板墩铁矿。其中,石板墩铁矿发育于中祁连地块西段龚岔群哈什哈尔组中,哈什哈尔组的时代一直被认为是新元古代青白口纪,但是缺少可靠的年代地层学和同位素年代学证据支撑,阻碍了祁连造山带内铁矿时代的对比和对成矿机制的认识。本文首次在哈什哈尔组下部碎屑岩中获得569±2 Ma的最大沉积年龄,表明含石板墩铁矿的哈什哈尔组的形成时代晚于569±2 Ma,可能属于新元古代晚期埃迪卡拉纪地层。同时,新的年代学证据还表明,该地区龚岔群之上多若诺尔群中可能的冰碛杂砾岩地层与中祁连地块邻区埃迪卡拉纪末期普遍发育的冰川沉积地层相当。本文首次明确了中祁连地块内埃迪卡拉纪地层的存在,表明中祁连西段前寒武纪地层时代需要重新系统修订,从而为认识该地区的构造演化史提供年代地层框架。

该研究以竹笋壳为原料合成了具有多孔结构和亲水性磷酸基团的羟基磷灰石改性竹笋壳生物炭(BSHAP),用于高效吸附废水中的铀酰离子(UO_(2)^(2+))。BS-HAP的多孔结构可有效增加与UO_(2)^(2+)的接触面积,促进对UO_(2)^(2+)的吸附;BS-HAP中的磷酸基团可为化学吸附UO_(2)^(2+)提供结合位点,使得BS-HAP对UO_(2)^(2+)具有优异的吸附性能。同时,Ca^(2+)与UO_(2)^(2+)之间的离子交换作用以及生物炭与UO_(2)^(2+)之间的静电相互作用,协同促进了BSHAP对UO_(2)^(2+)的吸附。在酸性条件下,BS-HAP对UO_(2)^(2+)的吸附容量为815.2 mg·g^(-1)。BS-HAP不仅对UO_(2)^(2+)具有强的吸附能力,还具有良好的选择性和稳定性,即使经多次循环使用,仍能保持对UO_(2)^(2+)的高效去除能力。BS-HAP为含铀废水处理提供了有效方法,对推动绿色可持续的废水处理技术发展具有重要意义。

The spectrum of a class of fourth order left-definite differential operators is studied. By using the theory of indefinite differential operators in Krein space and the relationship between left-definite and right-definite operators, the following conclusions are obtained： if a fourth order differential operator with a self-adjoint boundary condition that is left-definite and right-indefinite, then all its eigenvalues are real, and there exist countably infinitely many positive and negative eigenvalues which are unbounded from below and above, have no finite cluster point and can be indexed to satisfy the inequality …≤λ-2≤λ-1≤λ-0〈0〈λ0≤λ1≤λ2≤…

Fractal interpolation has been an important method applied to engineering in recent years. It can not only be used to fit smooth curve and stationary data but also show its unique superiorities in the fatting of non-smooth curve and non-stationary data. Through analyzing such characteristic values as average value, standard deviations, skewness and kurtosis of measured backsilting quantities in the Yangtze Estuary 12.5 m Deepwater Channel during2011–2017, the fractal interpolation method can be used to study the backsilting quantity distribution with *** to the fractal interpolation made on the channel backsilting quantities from January 2011 to December2017, there was a good corresponding relationship between the annual(monthly) siltation quantities and the vertical scaling factor. On this basis, a calculation formula for prediction of the backsilting quantity in the Yangtze Estuary Deepwater Channel was constructed. With the relationship between the predicted annual backsilting quantities and the vertical scaling factor, the monthly backsilting quantities can be obtained. Thus, it provides a new method for estimating the backsilting quantity of the Yangtze Estuary Deepwater Channel.

A theoretical study on the reaction of aluminum with water in the gas phase was performed using the hybrid density functional B3LYP and QCISD（T） methods with the 6-311＋G（d,p） and the 6-311＋＋G（d,p） basis sets. The results show that there are three possible reaction pathways that involve four isomers, seven transition structures, and two possible products for the reaction of aluminum with water. The two most favorable reaction pathways were found, whose intermediates and products agreed quite well with experimental results. The enthalpy and Gibbs free energy change of the reaction between A1 and H2O at 298 and 2000 K were calculated. Some results are also in good agreement with the previous calculations or experimental results.
