Fufang Xueshuantong （FXT） is a well-known Chinese herbal formula which has been used to treat car- diovascular and ophthalmic diseases, especially diabetic retinopathy. Panax notoginseng （Burkill） F.H. Chen （PN） is the main herb of FXT, whose major bioactive constituents are ginsenosides. However, the scientific basis of the compatibility of FXT is still ambiguous. The present study investigated the scientific basis of the compatibility of FXT by comparing the pharmacokinetics of marker compounds after oral administrations of PN and FXT. A high performance liquid chromatography-electrospray ionization tandem mass spectrometry （HPLC-ESI-MS/MS） method was devel- oped for simultaneous detection of notoginsenoside R1 （NR1）, ginsenoside Rgl （GRgl）, and ginsenoside Rbl （GRbl） in rat plasma. The pharmacokinetic studies of FXT and PN were performed using the established method with the pharmacokinetic parameters being determined by non-compartmental analysis. The results showed that the phar- macokinetic parameters （maximum concentration, area under the curve （AUC0-t）, clearance, and mean residence time） of NR1, GRgl, and GRbl were significantly different after oral administration of FXT （P〈0.05） compared with PN. The AUO0-t values of GRgl and GRbl were 1.7- and 3.4-fold greater, respectively, in FXT than in PN. The compatible herbs of FXT could prolong the retention time and increase the systemic exposure of NR1, GRgl, and GRbl compared with PN in vivo, providing some scientific basis for the compatibility and clinical use of FXT.

The lithium metal silicates （Li2MSiO4）（where M = Mn, Fe, and Co） have a great potential in rechargeable lithium ion batteries as polyanion cathodes, due to the immanent merits such as superior electrochemical properties, low cost, and abundance. However, these merits are suffered from lower electrical and ionic conductivities, owing to the effect of poor lithium ion extraction/insertion kinetics. By building hybrid architectures, the integrated composites may afford much promoting activities towards lithium ion batteries compared with the bare ones. Kinds of synthetic methods such as template method, sol-gel method, and hydrothermal method have been successfully applied to prepare lithium metal silicates based compounds and composite materials. In this review, we aim to present a general view of Li2MSiO4 for the recent progress. The relationship between nanoarchitectures and electrochemical performances is discussed. In the end, we also summarize the opportunities and challenges about Li2MSiO4 nanomaterials recently.

Danshen, the dried root of Salvia miltiorrhiza Bunge（Lamiaceae）, is one of the traditional Chinese medicines（TCMs） most commonly used for the treatment of cardiovascular and cerebrovascular diseases. However, little is known about the chemical and metabolic profiles of danshen in vitro or in vivo. In particular, more information is needed in relation to the 50% ethanol extracts usually used in danshen formulations such as Fufang Xueshuantong Capsules and Fufang Danshen tablets. High-performance liquid chromatography coupled with a linear ion trapOrbitrap mass spectrometer（HPLC-LTQ-Orbitrap） provides a sensitive and accurate method for analyzing the composition of samples. This method was used to determine the in vitro and in vivo chemical and metabolic profiles of danshen. Sixty-nine components of danshen extract and 118 components of danshen in rat plasma, urine, feces, and bile were unambiguously or tentatively identified. These results not only revealed the material composition of danshen, but also provided a comprehensive research approach for the identification of multi-constituents in TCMs.

The protective role of a human erythro-cyte-derived depressing factor (EDDF) on blood vessels was evaluated. The experiments were carried out on 25 male Wistar rats aged 6-8 weeks, which were divided into control (n=8), calcium overload (n=8) and NG-L-nitro-arginine hypertensive model groups (L-NNA, n = 9), respectively. The isolated vascular ring perfusion assay, two-photon laser scanning fluorescence microscopy (TPM) and transmitted electron microscope were used to examine the effect of EDDF on vascular function and ultrastructure. Results showed that the contractile response of calcium overload rats and L-NNA rats to phenylephrine (PE) was significantly enhanced compared with that of the control (P < 0.05), and EDDF (10-3g·mL-1) remarkably decreased the vascular contractile response of control’s and calcium overload rats (P < 0.05), while EDDF had no effect on that of L-NNA rats. EDDF also alleviated the ultrastructural lesion of aorta VSMC in calcium overload rats by easing the abnormal in the

Nowadays,Cu-based materials have attracted extensive attention as electrocatalysts,while the inherent reason of the filling of high anti-bonding state of Cu d band(3 d^(10)4 s^(1))makes it difficult to hybridize with O2 p band of oxygen intermediates during the adsorption process of oxygen evolution reaction(OER).To increase the efficiency of Cu-based electrocatalysts,efforts have been made to optimize the electronic structures and to create surface defects and hierarchical nanostructures with more exposed accessible active ***,we report a facile method for preparing CuO electrocatalysts with hierarchical nanostructures using the Cu-alanine complex as a precursor through room-temperature chemical precipitation and subsequent calcination in *** of products obtained at different calcination temperatures reveal the relationship between OER activities and the material characteristics such as specific surface areas,crystal growth orientations,and element *** product obtained at 500℃exhibits the smallest overpotential of 290 mV in 1.0 mol/L KOH for electrocatalyzing *** with various characterizations of CuO electrocatalysts after OER activities,the possible catalytic mechanism and the influence factors of their OER performance are also discussed.
