Background: Temperature is an essential condition in red ginseng processing. The pharmacological activities of red ginseng under different steam temperatures are significantly different. Methods: In this study, an ultrahigh-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry was developed to distinguish the red ginseng products that were steamed at high and low temperatures. Multivariate statistical analyses such as principal component analysis and supervised orthogonal partial least squared discrimination analysis were used to determine the influential components of the different samples. Results: The results showed that different steamed red ginseng samples can be identified, and the characteristic components were 20-gluco-ginsenoside Rf, ginsenoside Re, ginsenoside Rg1, and malonyl-ginsenoside Rb1 in red ginseng steamed at low temperature. Meanwhile, the characteristic components in red ginseng steamed at high temperature were 20R-ginsenoside Rs3 and ginsenoside Rs4. Polar ginsenosides were abundant in red ginseng steamed at low temperature, whereas higher levels of less polar ginsenosides were detected in red ginseng steamed at high temperature. Conclusion: This study makes the first time that differences between red ginseng steamed under different temperatures and their ginsenosides transformation have been observed systematically at the chemistry level. The results suggested that the identified chemical markers can be used to illustrate the transformation of ginsenosides in red ginseng processing.

Xu, Yan-Song,Zhao, Bo,Long, Chen-Yan,Li, Hui,Lu, Xing,Liu, Gang,Tang, Xiao-Zhun,Tang, Wei-Zhong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

Background: To evaluate relationship between the cyclooxygenase-2 promoter 765G/C polymorphism and digestive cancer risk in China. Materials and Methods: A literature search through February 2014 was performed using PubMed, Chinese Biomedical Literature Database (CBM) and China National Knowledge Infrastructure (CNKI) databases, and a meta-analysis was performed with RevMan 5.2 software for odds ratios and 95%CIs. Results: In total, 9 articles with 3,263 cases and 4,858 controls were included in this meta-analysis. The pooled OR (95%CIs) in the co-dominant model (GC vs GG) was 1.56 [1.19, 2.06], and in the dominant model ((CC+GC) vs GG), the pooled OR was 1.59 [1.21, 2.09] in overall cancers. In the subgroup analysis, stratified by cancer type, significant associations were found that the-765C allele had increased pancreatic cancer and gastric risk. No significant liver cancer and colorectal cancer risk of COX-2 -765G/C polymorphism was found. Conclusions: These findings suggest that COX-2-765*C is related to cancer susceptibility and may increase gastric and pancreatic cancer risk.

ANXA2, a member of the annexin family, is overexpressed and plays important roles in tumor development. However, the significance of ANXA2 expression in gastric carcinoma has not been clarified.To elucidate its roles in growth of gastric cancer, ANXA2 expression in SGC-7901 cells was inhibited with a designated siRNA, then cell proliferation, cell cycling, apoptosis and motility were determined by MTT assay, flow cytometry, Hoechst 33342 staining and wound healing assay, respectively. To further assess the behavior of ANXA2 deleted SGC-7901 cells, changes of microstructures were observed under fluorescence microscopy, laser scanning confocal microscopy and electron microscopy. We found that inhibition of ANXA2 expression caused cell proliferation to decrease significantly with G1 arrest, motility to be reduced with changes in pseudopodia/filopodia structure and F-actin and ${\beta}$-tubulin expression, and apoptosis to be enhanced albeit without significance. At the same time, ANXA2 deletion resulted in fewer pseudopodia/filopodia, non-stained areas were increased, contact inhibition among cells reappeared, and expression of F-actin and ${\beta}$-tubulin was decreased, with induction of polymerized disassembled forms. Taken together, these data suggest that ANXA2 overexpression is important to maintain the malignancy of cancer cells, and this member of the annexin family has potential to be considered as a target for the gene therapy of gastric carcinoma.

Yan Wan,Jing Wang,Jin-feng Xu,Fei Tang,Lu Chen,Yu-zhu Tan,Chao-long Rao,Hui Ao,Cheng Peng 고려인삼학회 2021 Journal of Ginseng Research Vol.45 No.6

Chemotherapy-induced side effects affect the quality of life and efficacy of treatment of cancer patients. Current approaches for treating the side effects of chemotherapy are poorly effective and may causenumerous harmful side effects. Therefore, developing new and effective drugs derived from natural nontoxiccompounds for the treatment of chemotherapy-induced side effects is necessary. Experimentsin vivo and in vitro indicate that Panax ginseng (PG) and its ginsenosides are undoubtedly non-toxic andeffective options for the treatment of chemotherapy-induced side effects, such as nephrotoxicity, hepatotoxicity,cardiotoxicity, immunotoxicity, and hematopoietic inhibition. The mechanism focus on antioxidation,anti-inflammation, and anti-apoptosis, as well as the modulation of signaling pathways, suchas nuclear factor erythroid-2 related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), P62/keap1/Nrf2, c-jun Nterminalkinase (JNK)/P53/caspase 3, mitogen-activated protein kinase (MEK)/extracellular signalregulatedkinases (ERK), AMP-activated protein kinase (AMPK)/mammalian target of rapamycin(mTOR), mitogen-activated protein kinase kinase 4 (MKK4)/JNK, and phosphatidylinositol 3-kinase(PI3K)/AKT. Since a systemic review of the effect and mechanism of PG and its ginsenosides onchemotherapy-induced side effects has not yet been published, we provide a comprehensive summarizationwith this aim and shed light on the future research of PG.

Aphelenchoides besseyi and Ditylenchus destructor can cause serious problems for a number of important agricultural crops and vegetables. In this study, the ethanol extract of Stellera chamaejasme L. roots showed strong nematicidal activity against Aphelenchoides besseyi and Ditylenchus destructor. By using a bioactivity-driven fractionation, three biflavonoids were isolated from the extract and their structures were identified by mass and nuclear magnetic resonance spectral data. Nematicidal activity bioassays revealed that isoneochamaejasmin A had the strongest nematicidal activity against A. besseyi and D. destructor with LC 50 values of 2.32 and 0.18 mM at 72 h, respectively. Chamaejasmenin B displayed weaker nematicidal activity against A. besseyi with an LC 50 value of 3.94 mM at 72 h. Neochamaejasmin B induced the lowest mortality against D. destructor with an LC 50 values of 15.6 mM at 72 h. These results suggested that the kind and position of substitutions and the relative configuration of 2-H/3-H and 2”-H/3”-H could be considered as important factors responsible for the nematicidal activity of these purified C-3/C-3″ biflavonoids.

Xu, Jia,Liu, Chang,Zhou, Lei,Tian, Feng,Tai, Ming-Hui,Wei, Ji-Chao,Qu, Kai,Meng, Fan-Di,Zhang, Ling-Qiang,Wang, Zhi-Xin,Zhang, Jing-Yao,Chang, Hu-Lin,Liu, Si-Nan,Xu, Xin-Shen,Song, Yan-Zhou,Liu, Jun,Z Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.2

Serum alpha-fetoprotein (AFP) is a significant marker for clinical diagnosis and prognosis evaluation in hepatocellular carcinoma (HCC) patients. However, some proportion of liver cancer patients are AFP-negative (AFP ${\leq}$20ng/ml). In order to study the differences between clinicopathological factors and prognosis of alpha-fetoprotein negative and positive patients, a total of 114 cases (41 AFP-negative and 73 AFP-positive) were selected for our research. By systematically statistical analysis, the results demonstrated that compared with AFP-negative patients, AFP-positive examples were more likely to feature cirrhosis nodules, non-complete neoplasm capsules, and a poor Edmondson-steiner grade. Furthermore, AFP-negative patients demonstrated a favorable long-term prognosis. By univariate analysis and multivariate analysis with Cox's proportional hazards model, multiple tumors were found to be independent risk factors for worse survival of AFP negative patients; however, less tumor-free margins, multiple tumors and Edmondson-steiner grades III/IV, proved to be independent risk factors leading to a poor prognosis of AFP positive cases. Finally, we can infer that high levels of AFP signify a highly malignant tumor and unfavorable prognosis.

The incorporation of porous nano-fillers into mixed matrix membranes (MMMs) has a great impact onCO2 separation. In this study, a series of F-Ln (Ln is the Light Lanthanide, Ln = La, Ce, Pr, Nd) nanosheetswith mesoporous structure was fabricated as a filler in Pebax1657 matrix to improve the performance ofCO2 separation. F-Ln nanosheets are uniformly distributed in the membrane and the mesoporous structurecan construct multiple channels for CO2 fast transport in Pebax/F-Ln MMMs. The pore diameter ofnanosheet is in order: F-La > F-Ce > F-Pr > F-Nd, and the smaller pore diameter of nanosheets is beneficialto improve the CO2 separation performance. In humidified conditions, Pebax/F-Nd-6 MMMs show optimumseparation performance among MMMs, and the CO2 permeability is up to 1265 Barrer and CO2/CH4selectivity is 36.7, which are 2.3 times and 1.9 times higher than pure Pebax and approaches 2019 upperbound. Meanwhile, to demonstrate the potential universal applicability of F-Ln nanosheets in CO2 separation,XLPEO/F-Ce MMMs were fabricated to separate CO2/N2 and the performance exceeds the 2019upper bound. The efficient CO2 separation performance of 2D F-Ln nanosheets with mesoporous structurein membranes reveals the potential application of these nanosheets in industrial CO2 separation.

Microstructure and viscoelastic behavior of waterborne polyurethane/cellulose nanofiber nanocomposite

Hui Zhao,Kui-Can Li,Wei Wu,Qing Li,Yan Jiang,Bing-Xu Cheng,Chong-Xing Huang,Hua-Nan Li 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.110 No.-

Cellulose nanofiber (CNF) has been widely used to reinforce the mechanical properties of waterbornepolyurethane (WPU). There are, however, few works that focus on structure, rheological behavior, andcreep resistance of WPU/CNF composites. To fill this research gap, in this work, the m-CNF was obtainedby c-aminopropyltriethoxysilane modification to improve the interfacial strength of CNF and WPU, andthen it was introduced into the polyurethane matrix. Structure characterization of WPU/m-CNFnanocomposites is performed using Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction(XRD), Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The obtainedresults show that with the increase of m-CNF, the hydrogen bonding index (HBI) increased, which meanta significant improvement in the mechanical properties. The tensile strength improved by 480%. Moreover, with the increase of m-CNF content, the viscosity, storage modulus, and loss modulus of thedispersions increased and showed more obvious shear-thinning behavior. In addition, m-CNF improvedthe thermal stability and creep resistance of WPU. The creep strain of WPU decreased from 3% to 0.2%. This work offers a simply feasible way to prepare environmental friendly green nanocomposites.

Tao, Hui,Si, Bingwen,Xu, Wencai,Tu, Yan,Diao, Qiyu Asian Australasian Association of Animal Productio 2020 Animal Bioscience Vol.33 No.5

Objective: The study was conducted to investigate the effects of Broussonetia papyrifera L. (B. papyrifera) silage on growth performance, serum biochemical parameters, meat quality, and meat amino acids and fatty acids compositions in beef cattle. Methods: Sixty-four male Angus beef cattle were assigned to 4 groups with 4 pens in each group and 4 beef cattle in each pen, and fed with the total mixed ration supplemented with 0%, 5%, 10%, or 15% B. papyrifera silage for 100 days (control group, 5% group, 10% group and 15% group) separately. Results: Beef cattle had significantly higher final body weight (BW) in 15% group, higher average daily gain (ADG) and dry matter intake (DMI) in 5% group, 10% group and 15% group, and higher feed conversion ratio (FCR) in 10% group and 15% group. Significantly higher blood superoxide dismutase (SOD) concentration was noted in 15% group, higher blood total antioxidant capacity (TAC) in 10% group and 15% group, lower 8-hydroxydeoxyguanosine (8-OHdG) and malondialdehyde (MDA) in 15% group. Meat had lower pH in 15% group, higher Commission International DeI'Eclairage (CIE) L^⋆ in 5% group, 10% group, and 15% group, and lower drip loss in 15% group. Greater concentration of meat polyunsaturated fatty acids (PUFA) was observed in 10% group and 15% group, and docosahexaenoic acid (DHA) in 15% group. Conclusion: Diet with 15% B. papyrifera silage could improve performance and increase final BW, ADG, DMI, and FCR, enhance the antioxidant functions by decreasing blood 8-OHdG and MDA and increasing blood SOD and TAC, improve the meat quality by lowing pH and drip loss and increasing CIE L^⋆, increase the meat PUFA and DHA concentration. Polyphenols and flavonoids might be the main components responsible for the antioxidant activity and anti-biohydrogenation in the B. papyrifera silage. And B. papyrifera silage could be used as a new feedstuff in beef cattle nutrition.
