BACKGROUND: Non-operative therapy takes an impor- tant position in comprehensive therapy of liver cancer. De- spite some effects by using ethanol, acetic acid and heat sa- line for intra-tumor injection in the treatment of liver canc- er, it is difficult to attain a complete cure but bring about injury to the liver to some extent. Hence, searching for other drugs for the local treatment of liver tumor is an im- portant option. This study was designed to set up rat mo- dels of transplanted liver cancer, intra-tumor injection of Kang-Lai-Te (KLT), and negative control (saline) and positive control (ethanol). The effect of intra-tumor injec- tion of KLT in treating transplanted hepatoma in rats and its advantages and disadvantages were assessed and the pos- sibility of its use in treating patients with liver cancer was evaluated. METHODS: Forty rats were divided into 4 groups ( G1, G2, G3 and G4, 10 rats in each group). Different drugs were injected into their implanted hepatoma (G1 with 0.2 ml saline as control, G2 with 10 mg KLT, G3 with 20 mg KLT, G4 with 0.2 ml ethanol). After 3 and 8 days, the hepa- toma volume (HV), the serum levels of albumin, alanine aminotransferase(ALT), aspartate aminotransferase alkaline phosphatase( ALP) and creatinine, as well as the expression of proliferation cell nuclear antigen (PCNA) in hepatoma were detected. RESULTS: After 3 days, the HVs were smaller in G3 and G4 than in G1 (P <0.05), the serum levels of albumin were higher in G2 and G3 than in Gl and G4 (P <0.05), the se- rum levels of ALT and AST were lower in G2 and G3 than in G4 (P<0.05), the serum levels of ALP was lower in G2 and G3 than in Gl and G4 (P <0. 05), the PCNA labeling indexes (PCNA LI) were lower in G2 and G3 than in Gl and GA (P <0.05). After 8 days, the HVs were smaller in G2, G3 and G4 than in Gl (P <0.05), and the differences of HVs among G2, G3 and G4 were not significant. The serum levels of ALP were lower in G1, G2 and G3 than in G4 (P <0.05), and the PCNA

In Earth system modeling, the land surface is coupled with the atmosphere through surface turbulent fluxes. These fluxes are computed using mean meteorological variables between the surface and a reference height in the atmosphere. However, the dependence of flux computation on the reference height, which is usually set as the lowest level in the atmosphere in Earth system models, has not received much attention. Based on high-resolution large-eddy simulation (LES) data under unstable conditions, we find the setting of reference height is not trivial within the framework of current surface layer theory. With a reasonable prescription of aerodynamic roughness length (following the setting in LESs), reference heights near the top of the surface layer tend to provide the best estimate of surface fluxes, especially for the momentum flux. Furthermore, this conclusion for the sensible heat flux is insensitive to the ratio of roughness length for momentum versus heat. These results are robust, whether using the classical or revised surface layer theory. They provide a potential guide for setting the proper reference heights for Earth system modeling and can be further tested in the near future using observational data from land-atmosphere feedback observatories.

The promotion of quantum network applications demands the scalable connection of quantum resources. It is preferable to set up multiple logical networks coexisting on a single physical network infrastructure to accommodate a larger number of *** we present a quantum virtual network architecture that offers this level of scalability, without being constrained to a fixed physical-layer network relying solely on passive multiplexing components. The architecture can be understood as arising from the superposition of a fully connected entanglement distribution network and port-based virtual local area network, which group multiusers by access ports. In terms of hardware, we leverage a semiconductor chip with a high figure-of-merit modal overlap to directly generate high-quality polarization entanglement, and a streamlined polarization analysis module, which requires only one single-photon detector for each end user. We experimentally perform the BBM92 QKD protocol on the five-user quantum virtual network and demonstrate voice and image encryption on a campus area network. Our results may provide insights into the realization of large-scale quantum networks with integrated and cost-efficient photonic architecture.

All-safe liquid-state lithium-ion batteries(ASLS-LIBs) is of great interest as they can potentially combine the safety of all-solid-state batteries with the high performance and low manufacturing cost of traditional liquid-state LIBs. However, the practical success of ASLS-LIBs is bottlenecked by the lack of advanced separator technology that can simultaneously realize high performances in puncturing-tolerability,fire-resistance, and importantly, wetting-capability with non-flammable liquid-electrolytes. Here, we propose a concept of inorganic in-situ separator(IISS) by hybrid-sol physical crosslinking directly onto the electrode surface to address the above challenges. Particularly, the hybrid-sol is designed with silica nanoparticles as the building block and poly(vinylidene difluoride) nanoparticles as the crosslinking agent. The critical factors for controlling the IISS microstructures and properties have been systematically investigated. The advantages of the IISS have been confirmed by its fast wetting with various fireresistant liquid-electrolytes, customizable thickness and porous structures, robust interface with planar or three-dimensional(3D)-structured electrodes, and importantly, unexpected self-adaptability against puncturing. Enabled by the above merits, a fire-resistant ASLS-LIB is successfully assembled and demonstrated with stable electrochemical performance. This sol-crosslinked IISS may open an avenue for the studies on the next-generation separator technology, cell assembling, solid electrolyte processing as well as non-flammable secondary batteries.

为提高生物质炭对水体中硝态氮(NO^(-)_(3)-N)的吸附潜力,在高温限氧条件(600℃)制备花生壳基生物质炭的基础上,利用铁(Fe^(3+))对其进行金属负载改性,通过批量吸附试验探讨其对NO^(-)_(3)-N的吸附机制。结果表明,改性生物质炭(FeHBC)在铁炭质量比为0.672时的吸附效果最好,改性后对NO^(-)_(3)-N的吸附能力得到显著提升(P0、ΔS>0,表明FeHBC对NO^(-)_(3)-N是自发的吸热过程,反应的自发性随温度升高而增大;酸性环境更有利于FeHBC对NO^(-)_(3)-N的吸附。除此之外,还结合扫描电子显微镜(SEM)、X射线衍射光谱(XRD)、傅里叶变换红外光谱(FTIR)、零电荷点(pH_(PZC))等表征手段对其吸附机制进行深入分析。结果表明,FeHBC形成的多微孔粗糙颗粒表面为其提供了更多的吸附位点,吸附过程可能主要受Fe^(3+)与含氧官能团络合沉淀反应的影响,与未改性相比其正电性增强,这一局部微结构的变化为提高生物质炭的吸附性能提供了理论支撑。
