ObjectiveTo explore the scientific connotation of fried charcoal survivability of Lonicerae Japonicae Flos（LJF） by analyzing the correlation between the color change and the intrinsic components during the processing of LJF Carbonisata（LJFC）， and taking pH， charcoal adsorption and microscopic characteristics as indexes. MethodLJFC samples with different degrees of processing were prepared according to the stir-frying time of 0.0， 1.5， 3.0， 4.5， 6.0， 7.5， 9.0， 10.5 min（numbered S1-S8）， and the contents of gallic acid， chlorogenic acid， cryptochlorogenic acid， rutin， luteoloside， isochlorogenic acid A and isochlorogenic acid C were determined by high performance liquid chromatography（HPLC）， and the L^*（brightness）， a^*（red-greenness） and b^*（yellow-blueness） of LJFC samples with different degrees of processing were determined by spectrophotometer， and the correlation analysis and principal component analysis（PCA） between the contents of seven representative components and the color of the samples were carried out by SPSS 26. 0 and SIMCA-P 14.1. Then pH， adsorption force and characteristic structure of different samples of LJFC were detected and the processing pattern of LJFC was analyzed. ResultThe results of quantitative analysis revealed that the contents of luteoloside， rutin， chlorogenic acid and isochlorogenic acid A gradually decreased， and the contents of cryptochlorogenic acid， isochlorogenic acid C and gallic acid firstly increased and then decreased. The L^* and b^* of the sample powders decreased， and a^* showed a trend of increasing and then decreasing. The L^* and b^* were positively correlated with the contents of chlorogenic acid， rutin， luteoloside， isochlorogenic acid A， b^* was positively correlated with the content of gallic acid， and a^* was positively correlated with the contents of cryptochlorogenic acid and isochlorogenic acid C. PCA revealed that samples could be clearly divided into 3 groups， S1-S2 as one group， S3-S5 as one group， and S6-S8 as one group， with S3 having the highest score. The results of regression analysis showed that only isochlorogenic acid C could be used to predict the contents of components by colorimetric values combined with regression equations. Physicochemical analysis showed that pH of LJFC increased with the increase of degree of charcoal stir-frying， while adsorption force showed a tendency of increasing and then decreasing， with the highest adsorption force in the S5 sample， and the non-glandular hairs， calcium oxalate clusters and pollen grains had a varying degree of decreasing with the deepening of processing degree， and the microstructures of S6-S8 samples were obviously charred with pollen grains almost invisible. ConclusionThe changes in chemical composition and color characteristics of LJFC during the processing have certain correlations， combined with the changes in physicochemical properties， S5 sample is found to be the optimal processed products， which can provide a reference for the processing standardization and quality evaluation of LJFC， and enrich the scientific connotation of fried charcoal survivability of LJF.

This study was aimed at exploring the effects of Toxoplasma gondii ROP16 Ⅰ/Ⅲ protein on the cell cycle,pro-liferation,and apoptosis of THP-1 cells via activation of STAT3 phosphorylation.ROP16 empty vector and recombinant lenti-viral overexpression vector were transfected into THP-1 cells,the fluorescence intensity was observed,and overexpression was verified.STAT3 and P-STAT3 protein expression in THP-1 cells overexpressing ROP16 Ⅰ/Ⅲ was detected by Western blot-ting.The cells were treated with the STAT3 phosphorylation inhibitor Stattic,and divided into a THP-1 group,THP-1+Stattic group,THP-1-ROP16 Ⅰ/Ⅲ group,and THP-1-ROP16Ⅰ/Ⅲ+Stattic group.Changes in the cell cycle,proliferation curve,and apoptosis rate were detected with flow cytometry and CCK-8 assays,and the expression levels of the apoptosis-related proteins Bax,Cleaved Caspase3,Caspase9,and Bcl-2 were detected by Western blotting.A strong fluorescence signal was ob-served after transfection of ROP16 recombinant lentivirus overexpression vector into THP-1 cells,and ROP16 mRNA and pro-tein expression significantly increased(FmRNA=314.1,Fprotein=758.7,P＜0.001),thus indicating successful construction of cell strains with stable overexpression.In addition,P-STAT3 protein showed higher expression in THP-1-ROP16 Ⅰ/Ⅲ group than the THP-1 group(F=606.1,P＜0.001).Flow cytometry and CCK-8 results indicated that,compared with the THP-1 group,the THP-1-ROP16 Ⅰ/Ⅲ group showed a cell cycle blocked in G1 phase,lower cell proliferation ability(t Ⅰgroup=19.2,tⅢgroup=24.0,P＜0.01),and a higher apoptosis rate(t Ⅰgroup=175.1,tⅢgroup=205.2,P＜0.001).Western blotting results also demonstrated significantly elevated expression of the intracellular pro-apoptotic proteins Bax,Cleaved Caspase3,and Caspase9(t Bax Ⅰgroup=15.8,tBaxⅢgroup=11.1,t Caspase9 Ⅰ group=9.1,t Caspaseg Ⅲ group=10.2,t Cleaved Caspase3 Ⅰ group=16.5,t Cleaved Caspase3 Ⅲ group=12.9,all P＜0.001),and significantly diminished expression of the anti-apoptotic protein Bcl-2(t Ⅰgroup=18.4,tⅢgroup=26.2,P＜0.001).However,after Stattic treatment,the cell cycle,proliferation ability,apoptosis rate,and expression of apoptosis-re-lated proteins in the THP-1-ROP16 Ⅰ/Ⅲ+Stattic group were restored to near baseline levels.Thus,Toxoplasma gondii ROP16 Ⅰ/Ⅲ proteins were found to block the THP-1 cell cycle at G1 phase,inhibit cell proliferation,and promote apoptosis by activating the phosphorylation of STAT3.

Aim To elucidate the molecular mechanism of Sophora tonkinensis Gagnep in improving acute pharyngitis based on network pharmacology, animal experiments and quantitative real-time PCR.Methods The active components and targets of Sophora tonkinensis Gagnep were collected from the database of traditional Chinese medicinal systems databases and analysis platform(TCMSP). Targets related to acute pharyngitis were acquired through GeneCards, OMIM, DrugBank and Disgenet databases. After the common targets of the two were screened, the STRING database was used to construct the protein interaction network, and the Metascape platform was used for pathway analysis. At the same time, Cytoscape software was used to construct a network of "herbal-disease-component-target" and "herbal-disease-component-target-pathway" network. The acute pharyngitis models in rats were established to study the effect of water extract of Sophora tonkinensis Gagnep on acute pharyngitis in rats. Quantitative real-time PCR technology was used to study the effect of Sophora tonkinensis Gagnep on key gene targets in key pathways of pharyngeal tissues in rats with acute pharyngitis. Results In this experiment, 509 related targets of 21 active components of Sophora tonkinensis Gagnep were obtained, 2 167 related targets of acute pharyngitis were obtained, and 194 common targets of Sophora tonkinensis Gagnep and acute pharyngitis were obtained. KEGG pathway analysis screened 344 related signaling pathways, indicating that IL-17 signaling pathway, NF-kappa B signaling pathway and leukocyte transendothelial migration pathway might play a key role in the improvement of acute pharyngitis by Sophorae tonkinensis Gagnep. Animal experiments showed that the low dose group of Sophora tonkinensis Gagnep water extract had better therapeutic effect on acute pharyngitis. The results of quantitative real-time PCR showed that the low-dose group of Sophora tonkinensis Gagnep significantly down-regulated the expression levels of ITGB2, PIK3CA, PIK3CD and PTPN11 genes in leukocyte transendothelial migration pathway(P<0.05). Conclusions The above results show that Sophora tonkinensis Gagnep has the characteristics of multi-component, multi-target and multi-pathway synergy in improving acute pharyngitis, which provides a theoretical basis for further study on the complex mechanism of Sophora tonkinensis Gagnep in improving acute pharyngitis.

The mechanism of ST induced nephrotoxicity was verified through animal experiments, and qRT-PCR was applied to detect mRNA expression level of key genes in kidney tissue. Results Twenty toxic components of ST were screened from network toxicology, mainly including matrine, sophoridine, maackiain. A total of 135 targets were involved, and HSP90AA1, SRC, MAPK1, MAPK3, AKT1 were the main targets. A total of 169 related signaling pathways were yielded by KEGG analysis, and the mechanism of nephrotoxicity might be related to cancer pathway, PI3K-Akt signaling pathway, HIF-1 signaling pathway, MAPK signaling pathway. PPARA, RAF1, MAP2K1, SRC, AKT1 and MAPK3 were screened from BioGPS database. The results of animal experiments showed that BUN and SCr level increased (P <0. 01) in rats with high-dose group, and the kidney tissue was significantly damaged. qRT-PCR results indicated that the expression of PPARA, RAF1, MAP2K1, MAPK3 mRNA increased, the expression of AKT1 mRNA decreased in the high-dose group of ST (P <0. 05). Conclusions The mechanism of Sophorae tonkinensis radix et rhizome induced nephrotoxicity is found to be related to the combined action of multiple components, multiple targets and multiple pathways, which also provides a theoretical basis for the in-depth exploration of the toxicology.
