Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

The modernization and development of traditional Chinese medicine has led to higher standards for the quality of traditional Chinese medicine products. The extraction process is a crucial component of traditional Chinese medicine production, and it directly impacts the final quality of the product. However, the currently relied upon methods for quality assurance of the extraction process, such as simple wet chemical analysis, have several limitations, including time consumption and labor intensity, and do not offer precise control of the extraction process. As a result, there is significant value in incorporating near-infrared spectroscopy (NIRS) in the production process of traditional Chinese medicine to improve the quality control of the final products. In this study, we focused on the extraction process of Xiao'er Xiaoji Zhike oral liquid (XXZOL), using near-infrared spectra collected by both a Fourier transform near-infrared spectrometer and a portable near-infrared spectrometer. We used the concentration of synephrine, a quality control index component specified by the pharmacopoeia, to achieve rapid and accurate detection in the extraction process. Moreover, we developed a model transfer method to facilitate the transfer of models between the two types of near-infrared spectrometers (analytical grade and portable), thus resolving the low resolution, poor performance, and insufficient prediction accuracy issues of portable instruments. Our findings enable the rapid screening and quality analysis of XXZOL onsite, which is significant for quality monitoring during the traditional Chinese medicine production process.

Based on the correlation of genetic differences and saponin content between individuals, a pair of specific primer GC1 was screened by PCR. According to the experiment by L16 (45) orthogonal test, a PCR system most suitable for GC1 was established, which came out total 25 μL reaction system containing DNA 2.60 mg•L⁻¹, Mg²⁺ 1.44 mmol•L⁻¹, dNTP 0.19 mmol•L⁻¹, primer 0.32 μmol•L⁻¹ and Taq enzyme concentration 0.076 U•μL⁻¹. By comparing the saponin content and the GC1 PCR electrophoretogram of samples, the ginseng, with 1 200 bp specific band by PCR of GC1, the contents of 9 monosodium saponins and their additions were higher than others, which provided a reliable method for accelerating the process of ginseng breeding. The sequence was sequenced and 99% homologous to glycerol-3-phosphate dehydrogenase.

Objective To determine the expression levels of zinc finger antisense 1 (ZFAS1) in tumor tissues of non-small cell lung cancer (NSCLC) and investigate the biological roles of ZFAS1 in NSCLC.Methods The relative expression levels of ZFAS1 in tumor tissues of NSCLC patients were determined by using real-time fluorescent qRT-PCR.RNA interference was used to knock down ZFAS1 expression in A549 cells.The proliferations of A549 cells with ZFAS1 knockdown were determined by cell counting and cell colony formation assays.Flow cytometric analysis was used to determine the cellular cycle distribution and apoptosis of the A549 cells with ZFAS1 knockdown.Transwell migration and matrigel invasion assays were used to determine the migration and invasion of the A549 cells with ZFAS1 knockdown.The gene expression levels of cyclin D1,Bcl2,N-cadherin,ZEB1,Slug and Twist were determined by real-time fluorescent qRT-PCR.Results The mean expression levels of ZFAS1 in tumor tissues of NSCLC patients [0.01 (0.002 to 0.054)] were significantly higher than those in the adjacent non-cancerous tissues [0.002 (0.001 to 0.012)] (Z =-2.638;P ＜ 0.01).After ZFAS1 knockdown,the proliferation of A549 cells was remarkably retarded (P ＜ 0.01).The percentage of cells at G1 phase was increased while the cells at S phase was decreased (P ＜ 0.01).The rate of apoptotic cells was significantly increased in A549 cells with ZFAS1 knockdown (P ＜ 0.01).A549 cells showed decreased migration and invasion abilities after ZFAS1 knockdown (P ＜0.01).The expression levels of cyclin D1,Bcl2,N-cadherin,ZEB1,Slug and Twist genes were decreased in ZFAS1 knockdown A549 cells (P ＜ 0.05).Conclusion ZFASI was highly expressed in the tumor tissues of NSCLC patients.ZFAS1 knockdown induced cell cycle arrest,cell apoptosis and suppression of epithelial-mesenchymal transition (EMT),leading to the inhibition of proliferation,migration,and invasion of NSCLC cells.
