Abstract
Cooperation and competition are the most common forms of social interaction in various social relationships. Intergroup relationships have been posited to influence individuals' interpersonal interactions significantly. Using electroencephalography hyperscanning, this study aimed to establish whether intergroup relationships influence interpersonal cooperation and competition and the underlying neural mechanisms. According to the results, the in-group Coop-index is better than the out-group, whereas the out-group Comp-index is stronger than the in-group. The in-group functional connectivity between the frontal-central region and the right temporoparietal junction in the β band was stronger in competition than cooperation. The out-group functional connectivity between the frontal-central region and the left temporoparietal junction in the α band was stronger in cooperation than competition. In both cooperation and competition, the in-group exhibited higher interbrain synchronization between the prefrontal cortex and parietal region in the θ band, as well as between the frontal-central region and frontal-central region in the α band, compared to the out-group. The intrabrain phase-locking value in both the α and β bands can effectively predict performance in competition tasks. Interbrain phase-locking value in both the α and θ bands can be effectively predicted in a performance cooperation task. This study offers neuroscientific evidence for in-group favoritism and out-group bias at an interpersonal level.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In China, Capparis spinosa L. fruits (CSF) are often used topically in Uyghur folk medicine in treating rheumatic diseases with remarkable efficacy. However, it has noticed severe skin irritation after a short time application with high dose of CSF, which limited long-term clinical use. To date, there is almost no research related to skin irritation of CSF. AIM OF THE STUDY This study was intended to perform the first systematic assessment of morphological and histological changes in skin after stimulation with CSF. Furthermore, potential irritant components in CSF and related mechanisms were explored by in vitro transdermal techniques, network pharmacology, molecular docking, and experimental validation. MATERIALS AND METHODS Skin changes after single and multiple stimulations with CSF were observed and subjected to skin irritation response scoring, irritation strength assessment, and histopathological analysis. In addition, in vitro transdermal technology, liquid chromatography-mass spectrometry (LC-MS) method, network pharmacology, molecular docking, and experimental validation were used to further exploit underlying skin irritant components and possible mechanisms of action. RESULTS CSF induced significant morphological (erythema and edema) and histological (epidermal thickening and inflammatory infiltration) changes in skin of mice, which were similar to the clinical presentation of irritation contact dermatitis (ICD). The ethyl acetate fraction of CSF (CFEAF) was the main source of CSF-induced skin irritation. Kaempferol, flazin, and gallic acid were potential major irritant compounds. Moreover, CFEAF, kaempferol, flazin, and gallic acid could increase the levels of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-α), intercellular adhesion molecule-1 (ICAM-1), and interleukin-17A (IL-17A) to promote skin inflammation. The potential mechanism of CSF-induced skin irritation may be activation of the nuclear factor kappa-B (NF-κB) signaling pathway, including phosphorylation of NF-κB p65 (p65) and nuclear factor-kappa B inhibitor alpha (IκBα). CONCLUSION Kaempferol, flazin, and gallic acid are potential skin irritant components from CSF. Altogether, they induce skin irritation responses through promoting the release of the inflammatory factors TNF-α and ICAM-1, as well as activating the NF-κB signaling pathway. In addition, IL-17A may be an important pro-inflammatory factor in skin irritation.

Abstract
Microbiota-derived catabolism of nutrients is closely related to ulcerative colitis (UC). The level of indole-3-acetic acid (IAA), a microbiota-dependent metabolite of tryptophan, was decreased significantly in the feces of UC patients. Thus supplementation with IAA could be a potential therapeutic method for ameliorating colitis. In this work, the protective effect of supplementation with IAA on dextran sulfate sodium (DSS)-induced colitis was evaluated, and the underlying mechanism was elucidated. The results indicated that the administration of IAA significantly relieved DSS-induced weight loss, reduced the disease activity index (DAI), restored colon length, alleviated intestinal injury, and improved the intestinal tight junction barrier. Furthermore, IAA inhibited intestinal inflammation by reducing the expression of proinflammatory cytokines and promoting the production of IL-10 and TGF-β1. In addition, the ERK signaling pathway is an important mediator of various physiological processes including inflammatory responses and is closely associated with the expression of IL-10. Notably, IAA treatment induced the activation of extracellular signal-regulated kinase (ERK), which is involved in the progression of colitis, while the ERK inhibitor U0126 attenuated the beneficial effects of IAA. In summary, IAA could attenuate the clinical symptoms of colitis, and the ERK signaling pathway was involved in the underlying mechanism. Supplementation with IAA could be a potential option for preventing or ameliorating UC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alzheimer's disease (AD) is a progressive developmental neurodegenerative disease that primarily develops in old age. Memory impairment is an important manifestation of AD. It has been demonstrated that inflammation and oxidative stress are important mediators in the development and progression of AD. Codonopsis Radix (CR) has a long history of consumption, exhibiting lots of beneficial health effects, including anti-ageing, antioxidant, and anti-inflammatory properties. However, studies on the effects of CR on scopolamine-induced amnesia have rarely been reported. AIM OF THE STUDY The aim of this study was to investigate the ameliorative effect of macromolecular portion (polysaccharides, POL) and small molecule portion (fine extract rich in phenylpropanoids-polyacetylenes, EPP) from CR on improving scopolamine-induced memory impairment and to elucidate the potential mechanism of action. MATERIALS AND METHODS C57BL/6 mice were pretreated with EPP (0.2, 0.4, and 0.6 g/kg), POL (0.3, 0.6, and 0.9 g/kg), and donepezil (5 mg/kg) by gavage for 7 days, followed by intraperitoneal injection of scopolamine (1 mg/kg) to induce memory impairment. The 16S rRNA gene sequencing, histopathological, western blotting, and biochemical analysis (various biochemical markers and protein expressions related to cholinergic system, oxidative stress, and neuroinflammation) were performed to further elucidate the mechanism of action. Moreover, the acetylcholinesterase (AChE) inhibitory activities of POL, EPP, and its main compounds tangshenoside I, lobetyol, lobetyolin, and lobetyolinin were evaluated. RESULTS Experiments have confirmed that both POL and EPP from CR could improve scopolamine-induced spatial learning memory deficits. Both of them could regulate cholinergic function by inhibiting AChE and activating choline acetyltransferase (ChAT) activities. They also could enhance antioxidant defense via increasing the activities of superoxide dismutase and glutathione peroxidase, and anti-inflammatory function through suppressing inflammatory factors (nitric oxide, TNF-α, and IL-6) and regulating gut flora. Besides, in vitro experiments demonstrated that four monomeric compounds and EPP, except POL, exhibited inhibition of AChE activity. CONCLUSION EPP and POL from CR exert a beneficial effect on learning and memory processes in mice with scopolamine-induced memory impairment. CR may be a promising medicine for preventing and improving learning memory.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fufangmuniziqi formula (FFMN), a traditional Uyghur medicine used in China, is derived from an ancient Uyghur medical book and consists of 13 herbs. The herbs of FFMN, such as Peganum harmala L., Glycyrrhiza uralensis Fisch., and Nigella glandulifera, have been demonstrated to have acetylcholinesterase (AChE) inhibitory, anti-neuroinflammatory, or antioxidant effects. Therefore, FFMN may have a good anti-Alzheimer's disease (AD) effect, but its specific action and mechanism need to be further proven. AIM OF THE STUDY This study aims to investigate the anti-AD effects of FFMN and the role played by alkaloids, flavonoids, and saponins in anti-AD. MATERIALS AND METHODS The alkaloids, flavonoids, and saponins fractions of FFMN were prepared by macroporous resin chromatography. The absorbed ingredients in the drug-containing serum were identified by UPLC⁃Q⁃TOF⁃MS. An AD mouse model was established by intraperitoneal injection of scopolamine (SCO). The role of different fractions of FFMN in the anti-AD process was examined by Morris water maze (MWM), in-vitro cell, and AChE inhibition assay. RESULTS A total of 20 ingredients were identified in the serum samples collected after oral administration of FFMN, and seven compounds were selected as candidate active compounds. MWM experiments showed that different fractions of FFMN could significantly improve SCO-induced learning memory impairment in mice. The alkaloids fraction (ALK) regulated cholinergic function by inhibiting AChE activity, activating choline acetyltransferase activity, and protein expression. Flavonoids and saponins were more potent than the ALK in downregulating pro-inflammatory factors or inflammatory mediators, such as TNF-α, MPO, and nitric oxide. Western blot results further confirmed that flavonoids and saponins attenuated neuroinflammation by inhibiting the phosphorylation of IκB and NF-κB p65. This result was also verified by in-vitro cellular assays. FFMN enhanced antioxidant defense by increasing the activity of superoxide dismutase and reducing the production of MDA. Combined with cellular experiments, flavonoids and saponins were proven more protective against oxidative damage. CONCLUSION FFMN improved cognitive and memory impairment in the SCO-induced AD mouse model. ALK mainly enhanced the function of the cholinergic system. Flavonoid and saponin fractions mainly attenuated neuroinflammation and oxidative stress by modulating the NF-κB pathway. All these findings strongly suggested that the combination of alkaloid, flavonoid, and saponin fractions derived from FFMN is a promising anti-AD agent that deserves further development.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Glehnia littoralis Fr. Schmidtex Miq. is a well-known perennial herb that is used in traditional medicine in China, Japan and Korea. G. littoralis has the effects of treating the lungs with heat, nourishing yin and blood, and acting as an expectorant. Traditional Chinese medicine (TCM) prescriptions containing G. littoralis have various clinical applications, such as clearing heat, relieving coughs, treating hepatic fibrosis, resolving phlegm, and treating esophagitis. AIM OF THE REVIEW This paper aims to provide a comprehensive and productive review of G. littoralis, mainly including traditional application, ethnopharmacology, chemical composition, pharmacological activities, and quality control. MATERIALS AND METHODS Literature search was conducted through the Web of Science, ScienceDirect, Springer Link, PubMed, Baidu Scholar, CNKI, and WanFang DATA by using the keywords "Glehnia littoralis", "Radix Glehniae", "Bei Shashen", "Clinical application", "Chemical composition", "Quality control" and "pharmacological action". In addition, information was collected from relevant ancient books, reviews, and documents (1980-2022). RESULTS G. littoralis is a traditional Chinese herbal medicine with great clinical value and rich resources. More than 186 components, including coumarins, lignans, polyacetylenes, organic acids, flavonoids, and terpenoids, have been isolated and identified from G. littoralis. The pharmacological activities of more than half of these chemicals are yet unknown. Polyacetylenes and coumarins are the most important bioactive compounds responsible for pharmacological activities, such as antiproliferative, anti-oxidation, anti-inflammatory, antibacterial, antitussive, immune regulation and analgesic. In this study, the progress in chemical analysis of G. littoralis, including thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (MS), and HPLC-MS, were summarized. CONCLUSION In this paper reviewed the previous literature regarding ethnopharmacological, phytochemical, pharmacological, and quality evaluation of the processing of G. littoralis was reviewed, providing potential reference information for future investigation and clinical applications. However, research on the relationship between chemical constituents and traditional uses of G. littoralis is lacking, and the comprehensive pharmacological effects and mechanisms of G. littoralis require further detailed exploration. In addition, an efficient method for chemical profiling is still unavailable to obtain potent bioactive markers for quality control. Perfect quality standards, which are also the basis for further drug development of G. littoralis, are urgently needed to ensure its quality and clinical application.

Abstract
Introduction Euryales Semen, a medicinal herb widely utilized in Asia, faces a critical constraint in its production, primarily attributed to fertilizer utilization. Understanding the impact of different fertilization schemes on Euryales Semen (ES) planting and exploring the supporting mechanism are crucial for achieving high yield and sustainable development of the ES planting industry. Methods In this study, a field plot experiment was conducted to evaluate the effects of four different fertilization treatments on the yield and quality of ES using morphological characteristics and metabolomic changes. These treatments included a control group and three groups with different organic fertilizer to chemical fertilizer ratios (3:7, 5:5, and 7:3). The results of this study revealed the mechanisms underlying the effect of the different treatments on the yield and quality of Euryales Semen. These insights were achieved through analyses of soil physicochemical properties, soil enzyme activity, and soil microbial structure. Results We found that the quality and yield of ES were the best at a ratio of organic fertilizer to chemical fertilizer of 7:3. The optimality of this treatment was reflected in the yield, soil available nitrogen, soil available phosphorus, and soil enzyme activity of ES. This ratio also increased soil microbial diversity, resulting in an increase and decrease in Proteobacteria and Firmicutes abundances, respectively. In addition, linear discriminant analysis showed that Chloroflexi, Gammaproteobacteria, and Hypocreales-incertae-sedis were significantly enriched in the ratio of organic fertilizer to chemical fertilizer of 7:3. Variance partitioning analysis showed that the soil properties, enzyme activities, and their interactions cumulatively can explain 90.80% of the differences in Euryales Semen yield and metabolome. In general, blending organic and chemical fertilizers at a 7:3 ratio can enhance soil fertility, boost Euryales Semen yield and quality, and bring forth conditions that are agriculturally beneficial to microbial (bacteria and fungi) dynamics. Discussion This study initially revealed the scientific connotation of the effects of different fertilization patterns on the planting of Euryales Semen and laid a theoretical foundation for the study of green planting patterns of Euryales Semen with high quality and yield.

Abstract
Here, we present an experimental investigation on the nonlinear optical (NLO) and optical limiting properties of metalloporphyrin compounds (Cu-1-OH, Zn-1-OH, Cu-1-E and Zn-1-E) using spatial self-phase modulation (SSPM) method in the visible range. It is found that all of the samples show a large self-defocusing effect at 532 nm, which is attributed to the thermal nonlinear optical effects with negative nonlinear refractive index coefficient n2 due to the relatively high absorption at 532 nm. In contrast, at 780 nm where absorption is weak for both Zn- and Cu-porphyrins, Zn-porphyrins still exhibit visible self-defocusing while Cu-porphyrins do not show any nonlinear diffraction pattern. Such a phenomenon can be explained by the Kerr effect of Cu-porphyrins at 780 nm. As the thermal nonlinear optical effects (of negative n2) at 780 nm are reduced due to the low absorption, the Kerr effect with positive n2 becomes comparable and the overall nonlinearity is reduced. The Kerr effect of Cu-porphyrins is stronger than that of Zn-porphyrins because of the enhanced π-electron delocalization effect as Cu(II) has a variable number of valence electrons and incompletely filled d atomic orbitals. Finally, the optical limiting performance of Zn-porphyrins is demonstrated as a representative and its dependence on sample position is examined. This work not only enriches the understanding of the physical mechanism of optical limiting in porphyrin materials, but also provides a significant reference to improve the third-order NLO coefficient by adjusting the structure of compounds.

Abstract
BACKGROUND During Fritillaria thunbergii planting, pests and diseases usually invade the plant, resulting in reduced yield and quality. Previous studies have demonstrated that using biocontrol agents can effectively control grubs and affect the steroid alkaloids content in F. thunbergii. However, the molecular regulatory mechanisms underlying the differences in the accumulation of steroid alkaloids in response to biocontrol agents remain unclear. RESULTS Combined transcriptomic and metabolic analyses were performed by treating the bulbs of F. thunbergii treated with biocontrol agents during planting. Otherwise, 48 alkaloids including 32 steroid alkaloids, 6 indole alkaloids, 2 scopolamine-type alkaloids, 1 isoquinoline alkaloid, 1 furoquinoline alkaloid, and 6 other alkaloids were identified. The content of steroidal alkaloids particularly peimine, peiminine, and veratramine, increased significantly in the group treated with the biocontrol agents. Transcriptome sequencing identified 929 differential genes using biocontrol agents, including 589 upregulated and 340 downregulated genes. Putative biosynthesis networks of steroid alkaloids have been established and combined with differentially expressed structural unigenes, such as acetyl-CoA C-acetyl-transferase, acelyl-CoAC-acetyltransferase3-hydroxy-3-methylglutaryl-coenzyme A synthase, 1-deoxy-D-xylulose-5-phosphate reductor-isomerase, 2-C-methyl-D-erythritol-4-phosphate cytidylyltransferase and 4-hydroxy-3-methylbut-2-enyl diphosphate reductase. In addition, biological processes such as amino acid accumulation and oxidative phosphorylation were predicted to be related to the synthesis of steroid alkaloids. Cytochrome P450 enzymes also play crucial roles in the steroid alkaloid synthesis. The transcription factor families MYB and bHLH were significantly upregulated after using biocontrol agents. CONCLUSIONS Biocontrol agents increased the steroid alkaloids accumulation of steroid alkaloids by affecting key enzymes in the steroid alkaloid synthesis pathway, biological processes of oxidative phosphorylation and amino acid synthesis, cytochrome P450 enzymes, and transcription factors. This study revealed the mechanism underlying the difference in steroidal alkaloids in F. thunbergii after using biocontrol agents, laying the groundwork for future industrial production of steroid alkaloids and ecological planting of medicinal materials in the future.

Abstract
Extremely severe and persistent particulate pollution caused by industrialization and urbanization impacts air quality, regional and global climates, and human health. The unstable and complex spectral signal of laser-induced breakdown spectroscopy (LIBS) with minimal feature information and interference signals considerably influences the accuracy of qualitative and quantitative analysis. In response to overcome this phenomenon, in this work, quantitative analysis of Cu element enhanced by silver nanoparticles (AgNPs) in a single microsized suspended particle was proposed herein using optical trapping-LIBS and machine learning method was proposed. Initially, the optimal AgNPs enhancement conditions were optimized. The LIBS spectra of 15 polluted black carbon samples were collected and various spectral pretreatment methods were compared to optimize the LIBS spectra. Variable selection methods include variable importance measurement (VIM), variable importance projection (VIP), VIM-successive projections algorithm (VIM-SPA), VIM-genetic algorithm (VIM-GA), and VIM-mutual information (VIM-MI). Finally, several hybrid variable selection methods were implemented in random forest (RF) calibration models. In particular, a wavelet transform (WT)-VIM-SPA-RF calibration model has constructed under the WT spectral pretreatment method and the selected and optimized input variables (VIM-SPA). Results elucidate that the WT-VIM-SPA-RF calibration model (R2P = 0.9858, MREP = 0.0396) have the best prediction performance than the WT-RF and Raw-RF models in predicting the Cu level in a single microsized black carbon particle. Compared to the WT-RF and Raw-RF models, MREP values decreased by 37% and 62%, respectively. The values of RSD, RPD, and RER of this calibration model are 2.8%, 8.39%, and 17.79%, respectively. The aforementioned results demonstrate that the WT-VIM-SPA-RF calibration model with accuracy, stability, and robustness is a promising approach for improving the quantitative accuracy of the Cu level in carbon black particles.

Abstract
The attribution of single particle sources of atmospheric aerosols is an essential problem in the study of air pollution. However, it is still difficult to qualitatively analyze the source of a single aerosol particle using noncontact in situ techniques. Hence, we proposed using optical trapping to combine gated Raman spectroscopy with laser-induced breakdown spectroscopy (LIBS) in a single levitated micron aerosol. The findings of the spectroscopic imaging indicated that the particle plasma formed by a single particle ablation with a pulsed laser within 7 ns deviates from the trapped particle location. The LIBS acquisition field of view was expanded using the 19-bundle fiber, which also reduces the fluctuation of a single particle signal. In addition, gated Raman was utilized to suppress the fluorescence and increase the Raman signal-to-noise ratio. Based on this, Raman can measure hard-to-ionize substances with LIBS, such as sulfates. The LIBS radical can overcome the restriction that Raman cannot detect ionic chemicals like fluoride and chloride in halogens. To test the capability of directly identifying distinctive feature compounds utilizing spectra, we detected anions using Raman spectroscopy and cations using LIBS. Four typical mineral aerosols are subjected to precise qualitative evaluations (marble, gypsum, baking soda, and activated carbon adsorbed potassium bicarbonate). To further validate the application potential for substances with indistinctive feature discrimination, we employed machine learning algorithms to conduct a qualitative analysis of the coal aerosol from ten different origin regions. Three data fusion methodologies (early fusion, intermediate fusion, and late fusion) for Raman and LIBS are implemented, respectively. The accuracy of the late fusion model prediction using StackingClassifier is higher than that of the LIBS data (66.7%) and Raman data (86.1%) models, with an average accuracy of 90.6%. This research has the potential to provide online single aerosol analysis as well as technical assistance for aerosol monitoring and early warning.

Abstract
Euryales Semen was a traditional Chinese medicine, which has been commonly used to treat spermatorrhea, enuresis, and frequent urination. Flavonoids were a critical ingredient in determining the function and quality of Euryales Semen. At present, no effective method has been established for the qualitative of Euryales Semen flavonoids. In this study, an ultra-high-performance liquid chromatography-quadrupole-time of flight-mass spectrometry method was established for flavonoids. By comparison with standard or literature data, 32 flavonoid compounds have been identified in Euryales Semen. Based on the qualitative results, an ultra-high-performance liquid chromatography-triple quadrupole tandem mass spectroscopy method was developed for the main components, and the linearity, the limit of detection, limit of quantification, repeatability, precision, stability, and recovery of the method were verified. The principal component analysis and the hierarchical clustering heatmaps analysis showed that the 30 batches of samples were distinctly separated into the North Gordon Euryale and South Gordon Euryale, and the measured contents of the six flavonoids in North Gordon Euryale were more abundant than in South Gordon Euryale, especially isoquercitrin, hesperetin, and quercetin. It provided a scientific basis for the quality control of Euryales Semen and a theoretical basis for the rational utilization of Euryales Semen resources.

Abstract
Cordycepin from Cordyceps possesses excellent pharmacological properties, including anti-inflammation and anti-tumor effects, therefore representing a potential alternative medicine. However, doubts about the pharmacokinetic results of cordycepin had been raised in the previous study due to its rapid deamination. The organic solvent methanol was immediately added to terminate the degradation of cordycepin in anticoagulated blood samples and enable the accurate evaluation of pharmacokinetics in vivo. A sensitive and selective ultra-high-performance liquid chromatography coupled with Q Exactive hybrid quadrupole orbitrap high-resolution accurate mass spectrometry method was developed and validated to simultaneously determine cordycepin and its deamination metabolite 3'-deoxyinosine using 2-chloroadenosine as an internal standard in rat whole blood. The calibration curves of cordycepin and 3'-deoxyinosine showed excellent linearity within the concentration range of 1.05-10 000.00 ng/ml with acceptable accuracy, precision, selectivity, recovery, matrix effect, and stability. This method was successfully applied to the pharmacokinetic study of cordycepin and its metabolite in rat blood. The effect of the adenosine deaminase inhibitor erythro-9-(2-hydroxy-3-nonyl) adenine hydrochloride on the pharmacokinetics of cordycepin was investigated. In summary, the reliable pharmacokinetic parameters of cordycepin and its deamination metabolite 3'-deoxyinosine in rat blood were successfully elucidated. Erythro-9-(2-hydroxy-3-nonyl) adenine hydrochloride considerably prolonged the half-life of cordycepin in vivo.

Abstract
The chemical compositions of atmospheric particles have been studied for several decades, and the traditional techniques for particle analysis usually require time-consuming sample preparation. Within this study, simultaneous quantitative detection of multiple metallic species (Zn, Cu, and Ni) in single micro-sized suspended particles was investigated by combining random forest (RF) and variable selection strategies. Laser-induced breakdown spectra of 15 polluted black carbon samples were applied for establishing the RF model, and the movmean smoothing spectral pretreatment method and variable selection methods [variable importance measurement (VIM), genetic algorithm (GA), and variable importance projection (VIP)] were proposed. Finally, the optimized RF calibration model with the evaluation indicators of mean relative error (MRE), root-mean-square error (RMSE), and coefficient of determination (R2) was constructed based on the optimal input variables and model parameters. Compared with the univariate regression method, the VIP-RF (Zn) and VIM-RF (Cu and Ni) models showed a better correlation relationship (Rp2 = 0.9662 for Zn, Rp2 = 0.9596 for Cu, and Rp2 = 0.9548 for Ni). For Zn, Cu, and Ni, the values of RMSEP (RMSE of prediction) decreased by 116.44, 68.94, and 102.10 ppm, while the values of MREP (MRE of prediction) decreased by 67, 55, and 48%, respectively. The values of ratio of prediction to deviation (RPD) of VIP-RF (Zn), VIM-RF (Cu), and VIM-RF (Ni) models were 5.4, 5.0, and 4.7, respectively. The performance of this combined approach displays a notable accuracy improvement in the quantitative analysis of single particles, suggesting that it is a promising tool for real-time air particulate matter pollution monitoring and control in the future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Asari Radix et Rhizoma (ARR), including 3 major plants of genus Asarum Linn, A. heterotropoides Fr. Schmidt var. mandshuricum (Maxim.) Kitag., A. sieboldii Miq. f. sieboldii and A. sieboldii Miq f. seoulense (Nakai) C. Y. Cheng et C. S. Yang, is one of the most important traditional herbal medicine in Asia with tremendous pharmacological activities. For a long time, researchers focus attention on studing asarinin and essential oils, the indicating ingredients of ARR, but paid less attention to another characteristic component, alkamides. The role of alkamides in the major efficacy of ARR medication remains to be elucidated. AIM OF THE STUDY This study aims to investigate the contribution of alkamides in the efficacy of ARR according to the evaluation of antinociceptive and anti-inflammatory effects and in vivo pharmacokinetics processes. MATERIALS AND METHODS For pharmacodynamic study, the analgesic and anti-inflammatory effects of alkamides-enriched fraction (ARRA) were comparatively evaluated by writhing test, hot plate test, and ear swelling test in mice after oral administration. For pharmacokinetic study, an UHPLC-MS/MS method was developed for the simultaneous determination of N-isobutyl-2E,4E,8Z,10Z/E-dodecatetraenamide (DDA) and other 6 major characteristic ingredients of ARR in rat plasma. The analytical method was validated and successfully applied to the pharmacokinetic study of ARR extract and DDA. RESULTS Pharmacodynamic study show that the ARR and ARRA can significantly inhibit the writhing times of mice caused by acetic acid administration, increase the pain threshold of thermal stimulation, and inhibit xylene treated ear swelling degree by reduce PGE2 and TNF-α levels in the inflamed tissue. For pharmacokinetic study, the pharmacokinetic parameters of Vd/F and CL/F after intravenous administration in rats of DDA are 63.94 ± 32.12 L/kg and 0.33 ± 0.06 L/min/kg, respectively. The plasma drug concentration declined with the T1/2 value of 2.25 ± 0.96 h, and the MRT0-∞ was 2.23 ± 1.02 h. The absolute bioavailability of DDA after oral administration was calculated as 10.73%. DDA, methyleugenol, and asarinin have relatively high AUC0-∞ values when the ethanol and water extract of ARR is orally administered. CONCLUSIONS ARRA is a kind of active ingredients with potential analgesic and anti-inflammatory effects that played a significant role in the major efficacy of ARR. DDA, the major compound of ARRA, has a high level of exposure in vivo, which could be is suitable for the pharmacokinetic marker or new quality marker of ARR.

Abstract
Asari Radix et Rhizoma (AR) is a widely-used Chinese herbal medicine containing multiple active lignans and rare nephrotoxic components-aristolochic acids derivatives (AAs). However, the current quality control method carried out by Chinese Pharmacopoeia has defects in trace AAs detection and insufficient marker ingredients, which is unable to comprehensively evaluate the efficacy and safety of AR. To improve the quality control method of AR, a rapid, sensitive, and reliable chromatographic analytic method based on ultra-high-performance liquid chromatography-triple quadrupole tandem mass spectrometry (UHPLC-QqQ-MS) was established for the simultaneous analysis of multiple AAs and lignans in AR samples. Positive electrospray ionization mode with multiple reaction monitoring (MRM) was applied for the detection of the eight analytes. The method showed available linearity (R 2 ≥ 0.991), the limit of quantification (2-5 ng/mL), precision (RSD <8.12%), and accuracy (89.78-112.16%). A total of 6 AAs and 2 lignans were quantified for their content in 15 AR samples. The content of AA-IVa, AA-VIIa, and aristololactam I (AL-I) was much higher than the AA-I controlled by pharmacopoeia. Considering the potential toxicity of AAs, AA-IVa, AA-VIIa, and AL-I should also be controlled in AR. A considerable amount of active sesamin was detected in AR, suggesting that it could be added as a quality marker for the quality control of AR. The newly developed analytical method could be applied for the fast evaluation of toxic AA's content and quality during quality control of AR or preparations containing AR.

Abstract
Luhong recipe (LHR) is an empirical prescription for the treatment of chronic heart failure for a long time, with safety, reliability and significant efficacy. However, its pharmacokinetics have not been studied. This study was to establish a UHPLC-MS/MS method for the simultaneous analysis of epimedin A, epimedin B, epimedin C, icariin, psoralen, isopsoralen in rat plasma, and apply it to the pharmacokinetic study of LHR after oral administration. These six analytes were ionized by electrospray positive ionization (ESI+ ). The MS/MS transitions used for monitoring is successively converted to m/z 839.3→369.1, m/z 809.2→369.1, m/z 823.3→369.1, m/z 677.2→205.2, m/z 187.1→115.2 and m/z 230→120.9. The linearity, precision, accuracy, stability, matrix effect and recovery of the established method were within the acceptable range. It was suitable for the determination of six analytes after oral administration LHR. The pharmacokinetic results showed the time to reach the peak concentration (Tmax ) was 0.17-13.5h, the peak concentration (Cmax ) was 109.23-980 ng/mL, the area under the concentration time curve (AUC(0-t) ) was 65.48-8846.08 ng·h/mL, and the apparent distribution volume (Vd) was 24772-896132 mL/kg. These results provided a meaningful basis for formulating the clinical dose regimen of LHR.

Abstract
The capacity for the implicit learning/processing of complex grammar with nonadjacent dependencies is one of important features of human language learning. In this fMRI study, using an implicit AGL paradigm, we explored the neural basis of the implicit learning of the nonadjacent dependency rule, disentangling from sequence-based chunk knowledge (i.e., local sequential regularities or substring) by focusing on the low chunk strength items (which were naturally less similar to training strings), based on tracking neural responses during training and test phases. After listening to and memorizing a series of strings of 10 syllables generated from nonadjacent artificial grammar in the training phase, participants implicitly acquired the knowledge of grammar and chunks. Regarding grammaticality, Broca's area was specifically related to low chunk strength grammatical strings relative to nongrammatical strings in the test phase. This region showed decreased activity with time in the training phase, and a lesser decrease in activity was associated with higher performance in grammar learning. Furthermore, Broca's area showed significantly higher strength of functional connectivity with the left superior temporal gyrus in the low chunk strength grammatical string compared with nongrammatical strings, and this functional connectivity increased with the training time. For the chunks, the performance of accurate discrimination of high chunk strength from low chunk strength nongrammatical strings was predicted by hippocampal activity in the training phase. Converging evidence from the training and test phases showed that Broca's area and its functional connectivity with the left superior temporal gyrus were engaged in the implicit learning/processing of the nonadjacent dependency rule, separating the effects of chunks.

Abstract
BACKGROUND Amygdalin (Amy) is a cyanoside and is one of the chief active ingredients in Persicae Semen, Armeniacae Semen Amarum, and Pruni Semen. Amy has extensive and remarkable pharmacological activities, including against anti-hepatic fibrosis. However, the pharmacokinetic and anti-liver fibrosis effects of Amy and its enzyme metabolite prunasin (Pru) in vivo have not been studied and compared, and studies on Pru are limited. PURPOSE To investigate the pharmacokinetic characteristics and anti-liver fibrosis effect of Amy and its metabolite Pru in vivo and in vitro, and elucidate whether the metabolism of Amy in vivo for Pru is activated. METHODS Pru was prepared from Amy via the enzymatic hydrolysis of β-glucosidase, and isolated by silica gel column chromatography. An efficient and sensitive ultrahigh-performance liquid chromatography-Q exactive hybrid quadrupole orbitrap high-resolution accurate mass spectrometry was developed and validated to determine simultaneously Amy and Pru in rat plasma after dosing intravenously and orally for pharmacokinetic studies. The affinities of Amy and Pru for β-glucosidase were compared by enzyme kinetic experiments to explain the possible reasons for the differences in pharmacokinetic behavior. In vitro, the inhibitory effects of Amy and Pru on hepatic stellate cell activation and macrophage inflammation on JS1 and RAW 264.7 cells were determined. In vivo, the ameliorative effects of Amy and Pru on liver fibrosis effects were comprehensively evaluated by CCl4-induced liver fibrosis model in mice. RESULTS The standard curves of Amy and Pru in rat plasma showed good linearity within the concentration range of 1.31-5000.00 ng/ml, with acceptable selectivity, carry-over, detection limit and quantification limits, intra- and inter-day precision, accuracy, matrix effect, and stability. The Cmax and AUC(0-∞) of Pru (Cmax = 1835.12 ± 268.09 ng/ml, AUC(0-∞) = 103,913.17 ± 14,202.48 ng•min/ml) were nearly 79.51- and 66.22-fold higher than those of Amy (Cmax = 23.08 ± 5.08 ng/ml, AUC(0-∞) = 1569.22 ± 650.62 ng•min/ml) after the oral administration of Amy. The oral bioavailability of Pru (64.91%) was higher than that of Amy (0.19%). The results of enzyme hydrolysis kinetics assay showed that the Vmax and Km of Pru were lower than those of Amy in commercial β-glucosidase and intestinal bacteria. In vitro cellular assays showed that Amy and Pru were comparable in inhibiting the NO production in the RAW264.7 cell supernatant and the mRNA expression of α-SMA and Col1A1 in JS1 cells. Amy and Pru were also showed comparable activity in ameliorating CCl4-induced liver fibrosis in mice. CONCLUSION The pharmacokinetic characteristics of Amy and Pru in rat plasma were significantly different. After the separate gavage of Amy and Pru, Amy was absorbed predominantly as it's metabolite Pru, whereas Pru was absorbed predominantly as a prototype. The anti-liver fibrosis effects of Amy and its deglycosylated metabolite Pru were comparable in vivo and in vitro. The deglycosylated activated metabolite Pru of Amy plays an important role in anti-liver fibrosis. These findings will facilitate the further exploitation of Amy and Pru.

Abstract
We report on ultra-high harmonic mode-locking with a repetition rate of up to ∼1 THz by combining a microfiber knot resonator (MKR) and a Lyot filter. The harmonic mode-locked pulses are tunable by changing the diameter of MKR, which agrees well with the theoretical calculation. Our results indicate that the ultrafast pulse generation mechanism is due to the dissipative four-wave mixing mode-locking technique. This work provides a simple and efficient scheme to generate tunable ultrafast pulses with a high repetition rate for various applications, such as THz generation and ultrafast data communication.

Abstract
INTRODUCTION Codonopsis Radix (CR) is an edible food and traditional Chinese herb medicine that is widely used in China and Southeast Asia. Saccharides, including fructo-oligosaccharides (FOS) and polysaccharides, are among the most important active substances in CR. However, a quality evaluation of CR based on oligosaccharides has not been conducted. OBJECTIVE This study aimed to establish a high-performance liquid chromatography coupled with charged aerosol detector method (HPLC-CAD) for the quality evaluation of CR and processed products based on analysis of monosaccharides and oligosaccharides. METHOD A sensitive and rapid HPLC-CAD method for the simultaneous determination of two monosaccharides (D-fructose and D-glucose), sucrose, and FOS (GF2-GF6) was established to evaluate the quality of CR for the first time. In the present study, 65 batches of CR from three species of the genus Codonopsis were analysed using multivariate statistical techniques. Furthermore, the effects of cultivation management measures (plant growth retardants supply, harvesting time, and growth period) and primary process (drying methods) in the production areas on the target compounds were studied by analysing 34 batches of processed samples. RESULTS Different varieties of CR resulted in considerably different saccharide contents. Cultivation management measures and processing method remarkably affected the quality of CR. Low concentration of plant growth retardants was recommended. The best harvest time is in October after 4 years of growth. Dryer-drying was suggested to meet the requirement for large-scale processing. CONCLUSION This method would provide an efficient analytical tool for monosaccharides and oligosaccharides of CR and contribute to the improvement of CR quality.

Abstract
OBJECTIVE Several β-carboline alkaloids (βCBs), such as harmine, harmaline, harmane, and nor-harmane, are effective for Alzheimer's disease mouse models. They can be found in some plants, common foodstuffs, and blank plasma of various mammals. However, whether these compounds in mammals are exogenous or endogenous remain unclear. METHODS The exposure levels of βCBs and of neurotransmitters in plasma and tissues of pup rats, aging rats, mice of different physiological states, and healthy volunteers were detected by using UPLC-MS/MS. Plasma and tissue samples from 110 newborn rats up to 29 days old at 11 sampling points were collected and were analyzed to determine the concentration variation of βCBs in the developmental phase of newborn rats. The plasma of rats aged 2 to 18 months was used to detect the variation trend of βCBs and with some neurotransmitters. The plasma samples of normal C57BL/6 mice, APP/PS1 double transgenic mice, and scopolamine-induced memory impairment mice were collected and were analyzed to compare the difference of βCBs in different physiological states. The exposure levels of βCBs such as harmine, harmaline, and harmane in plasma of 550 healthy volunteers were also detected and analyzed on the basis of gender, race, and age. RESULTS Results showed that harmine was the main compound found in rats, mice, and human, which can be detected in a newborn rat plasma (0.16 ± 0.03 ng/ml) and brain (0.33 ± 0.14 ng/g) without any exogenous consumption. The concentration of harmine in rat plasma showed a decreasing trend similar to the exposure levels of neurotransmitters such as 5-hydroxytryptamine, acetylcholine chloride, glutamic acid, tyrosine, and phenylalanine during the growth period of 18 months. The harmine exposure in rats and human indicates high dependence on the physiological and pathological status such as aging, gender, and race. CONCLUSION The dynamic changes of harmine exposure in different animals and human, in vivo, at developmental and physiological states indicate that harmine is a naturally and widely distributed endogenous substance in different mammals and human. In addition to exogenous ingestion, spontaneous synthesis might be another important source of harmine in mammals, which should be verified by further experiment.

Abstract
We report tuning of the moduli and surface roughness of magnetorheological elastomers (MREs) by varying applied magnetic field. Ultrasoft MREs are fabricated using a physiologically relevant commercial polymer, Sylgard™ 527, and carbonyl iron powder (CIP). We found that the shear storage modulus, Young's modulus, and root-mean-square surface roughness are increased by ~41×, ~11×, and ~11×, respectively, when subjected to a magnetic field strength of 95.5 kA m-1. Single fit parameter equations are presented that capture the tunability of the moduli and surface roughness as a function of CIP volume fraction and magnetic field strength. These magnetic field-induced changes in the mechanical moduli and surface roughness of MREs are key parameters for biological applications.

Abstract
Herbal medicines have historically been practiced in combinatorial way, which achieves therapeutic efficacy by integrative effects of multi-components. Thus, the accurate and precise measurement of multi bioactive components in matrices is inalienable to understanding the metabolism and disposition of herbal medicines. In this study, aiming to provide a strategy that improves analyte coverage, evaluation of six protocols employing sample pretreatment methods- protein precipitation (PPT), liquid-liquid extraction (LLE), sugaring-out-assisted liquid-liquid extraction (SULLE), and salting-out-assisted liquid-liquid extraction (SALLE)- was performed by LC-MS/MS using rat plasma and a mixture of alkaloid (evodiamine, rutaecarpine, dehydroevodiamine), terpenoid (limonin, rutaevin, obacunone), and flavonoid (liquiritin, isoliquiritin, liquiritigenin) standards isolated from Tetradium ruticarpum and Glycyrrhiza uralensis. These protocols were as follows: (1) PPT with methanol, (2) PPT with acetonitrile, (3) LLE with methyl tertiary-butyl ether-dichloromethane, (4) LLE with ethyl acetate-n-butanol, (5) SALLE with ammonium acetate, (6) SULLE with glucose. The results suggested that SALLE produced broader analyte coverage with satisfactory reproducibility, acceptable recovery, and low matrix interference. Then, sample preparation procedure of SALLE, chromatographic conditions, and mass spectrometric parameters were optimized, followed by method validation, showing that good sensitivity (LLOQ ≤ 1 ng mL-1), linearity (r ≥ 0.9933), precision (RSD ≤ 14.45%), accuracy (89.54~110.87%), and stability could be achieved. Next, the developed method was applied successfully to determine the pharmacokinetic behavior of the nine compounds in rat plasma after intragastric administration with an extract from Tetradium ruticarpum and Glycyrrhiza uralensis (Wuzhuyu-Gancao pair). Based on an extensive review and experiments, a sample preparation procedure that matches with LC-MS/MS technique and can get wider analyte coverage was outlined. The developed SALLE method is rapid, reliable, and suitable for bioanalysis of analytes with diverse polarity, which was expected to be a promising strategy for the pharmacokinetic studies of herbal medicines.

Abstract
Dictamnine (DIC), a typical furan-quinoline alkaloid, has a wide range of pharmacological and toxicological effects, such as anti-bacterial, antifungal, anti-cancer, and hepatoxicity. But the molecular mechanism of DIC-induced hepatoxicity in mice remains unclear. This study aimed to clarify the biotransformation patterns of DIC in vitro/in vivo and the relative molecular mechanism of DIC-induced hepatoxicity in mice. All metabolites of DIC were identified by comparing the blank and drug-containing urine, feces, plasma, and liver samples. The structure of epoxide intermediate derived from DIC was confirmed by trapping assay. Oxidative stress injury and inflammation have been confirmed to be involved in the toxicological process of DIC-induced hepatoxicity in mice by detecting the relative biochemical indexes. The results will help to develop a deeper understanding about the biotransformation patterns of DIC, structure of the epoxide intermediate, and the molecular mechanism of DIC-induced hepatoxicity in mice.

Abstract
Current methods to dynamically tune three-dimensional hydrogel mechanics require specific chemistries and substrates that make modest, slow, and often irreversible changes in their mechanical properties, exclude the use of protein-based scaffolds, or alter the hydrogel microstructure and pore size. Here, we rapidly and reversibly alter the mechanical properties of hydrogels consisting of extracellular matrix proteins and proteoglycans by adding carbonyl iron microparticles (MPs) and applying external magnetic fields. This approach drastically alters hydrogel mechanics: rheology reveals that application of a 4000 Oe magnetic field to a 5 mg/mL collagen hydrogel containing 10 wt % MPs increases the storage modulus from approximately 1.5 to 30 kPa. Cell morphology experiments show that cells embedded within these hydrogels rapidly sense the magnetically induced changes in ECM stiffness. Ca2+ transients are altered within seconds of stiffening or subsequent softening, and slower but still dynamic changes occur in YAP nuclear translocation in response to time-dependent application of a magnetic field. The near instantaneous change in hydrogel mechanics provides new insight into the effect of changing extracellular stiffness on both acute and chronic changes in diverse cell types embedded in protein-based scaffolds. Due to its flexibility, this method is broadly applicable to future studies interrogating cell mechanotransduction in three-dimensional substrates.

Abstract
Codonopsis pilosula is a traditional Chinese medicine and food supplement that is widely used in China. This study aimed to investigate the antifatigue and antihypoxia activities of different extracts and fractions from C. pilosula, including ethanol extract (ETH), water extract (WAT), polysaccharides (POL), inulin (INU) and oligosaccharides (OLI). Different extracts and fractions were orally administered to mice at the doses of 0.25, 0.5 and 1.0 g kg-1 once a day for 21 days. Antifatigue activity was assessed through the weight-loaded swimming test on the 21st day, and antihypoxia activity was evaluated through the normobarie hypoxia test on the following day. Finally, biochemical parameters, such as liver glycogen (LG), muscle glycogen (MG), blood urea nitrogen (BUN), lactic dehydrogenase (LDH), malondialdehyde (MDA), and glutathione (GSH) levels, were determined. The results showed that, compared with the control treatment, only POL treatment significantly prolonged the swimming time of the mice. POL groups had the strongest hypoxia tolerance, followed by the OLI and WAT groups. The levels of LG and MG were significantly increased by treatment with POL at the doses of 0.5 and 1.0 g kg-1, whereas BUN and LDH levels in POL groups were significantly lower than those in the control group. MDA under POL and OLI treatment was significantly lower than that under the control treatment. In addition, treatments with POL and OLI, except for treatment with a low dose of OLI, significantly increased GSH levels. In conclusion, POL could efficiently enhance antifatigue and antihypoxia abilities by increasing energy resources, decreasing detrimental metabolite accumulation, and enhancing antioxidant activity. OLI could improve antihypoxia activity by preventing lipid peroxidation and enhancing antioxidant activity.

Abstract
A rapid ultra-fast liquid chromatography tandem mass spectrometry method was developed and validated to determine ginsenosides Rk1 and Rg5, a pair of isomers, in rat plasma, which was successfully applied to their pharmacokinetic studies. Two ginsenosides were given to male Sprague-Dawley rats via intragastrical and intravenous routes, respectively, and the impact of double bond position on the pharmacokinetic features of the two ginsenosides was elucidated in rats. Ginsenoside Rg3 was used as internal standard and ethyl acetate was applied to extract analytes and internal standard. Chromatographic separation was carried out on a reverse-phase UPLC HSS T3 column (100 × 2.1 mm, 1.8 μm). The flow rate was set to 0.4 ml/min. The fragmentation transition was m/z 765.4 → m/z 101.1 for two ginsenosides. The mobile phases were composed of 0.1% formic acid aqueous solution and acetonitrile. The linear range was 2-1,000 ng/ml for the two ginsenosides. Intra- and inter-day precisions were <11.67%, and accuracy fluctuated from -7.44 to 6.78%. The extraction recovery, matrix effect and stability were within acceptable levels. After treatment with ginsenosides Rk1 and Rg5, some differences were found in their pharmacokinetic profiles in rats. The maximum plasma drug concentration and the area under the plasma drug concentration-time curve of ginsenoside Rg5 were about 5 times bigger than those of ginsenoside Rk1 after oral administration, and 3 times higher after intravenous administration. The oral bioavailabilities of ginsenosides Rk1 and Rg5 were 0.67 and 0.97%, respectively. The results indicated that ∆20(22) -ginsenosides showed better pharmacokinetic features than ∆20(21) -ginsenosides with the same glycosylation.

Abstract
Elemental identification of individual microsized aerosol particles is an important topic in air pollution studies. However, simultaneous and quantitative analysis of multiple constituents in a single aerosol particle with the noncontact in situ manner is still a challenging task. In this work, we explore the laser trapping-LIBS-machine learning to analyze four elements (Zn, Ni, Cu, and Cr) absorbed in a single micro-carbon black particle in air. By employing a hollow laser beam for trapping, the particle can be restricted in a range as small as ∼1.72 μm, which is much smaller than the focal diameter of the flat-topped LIBS exciting laser (∼20 μm). Therefore, the particle can be entirely and homogeneously radiated, and the LIBS spectrum with a high signal-to-noise ratio (SNR) is correspondingly achieved. Then, two types of calibration models, i.e., the univariate method (calibration curve) and the multivariate calibration method (random forests (RF) regression), are employed for data processing. The results indicate that the RF calibration model shows a better prediction performance. The mean relative error (MRE), relative standard deviation (RSD), and root-mean-squared error (RMSE) are reduced from 0.1854, 363.7, and 434.7 to 0.0866, 179.8, and 216.2 ppm, respectively. Finally, simultaneous and quantitative determination of the four metal contents with high accuracy is realized based on the RF model. The method proposed in this work has the potential for online single aerosol particle analysis and further provides a theoretical basis and technical support for the precise prevention and control of composite air pollution.

Abstract
Stem-leaf saponins (SLSs), the total saponins from aerial part of P. notoginseng, are by-products of notoginseng, a famous traditional Chinese medicine. SLSs have been used as a health functional food in China, but its mild effects limited clinical applications in diseases. Inspired by steaming of notoginseng to enhance its pharmacological activity, a steaming protocol was developed to treat SLSs. SLSs were steamed at 100, 120, and 140°C for 1, 2, 3, and 4 h, respectively. The ultra-performance liquid chromatography coupled with quadrupole time-of-flight MS and ultra-performance liquid chromatography-tandem triple quadrupole mass spectrometry were applied to analyze the dynamic changes in chemical compositions. The anti-acetylcholinesterase activity of steamed SLS were assessed in vitro by directly determining the metabolic product of acetylcholine/choline. The components of SLSs were significantly changed by steaming. A total of 117 saponins and aglycones were characterized, and 35 of them were newly generated. The anti-acetylcholinesterase activity of steamed SLSs gradually increased with the extension of steamed time and the increase of steamed temperature and reached the maximum after 140°C for 3 h. Furthermore, ginsenosides Rk1 and Rg5, the main components of steamed SLSs, showed dose-dependent anti-acetylcholinesterase activities with half maximal inhibitory concentration (IC50 ) values of 26.88 ± 0.53 μm and 22.41 ± 1.31 μm that were only 1.8- and 1.5-fold higher than that of donepezil with IC50 values of 14.93 ± 4.17 μM, respectively.

Abstract
OBJECTIVES Early childhood experiences influence cognitive-emotional development, with insecure attachment predisposing to potential psychopathologies. We investigated whether narratives containing attachment-specific speech patterns shape listeners' emotional responses and social intentions. DESIGN First, 149 healthy participants listened to three narratives characteristic for secure, insecure-preoccupied, and insecure-dismissing attachment. Following each narrative, the well-being and interpersonal reactivity as a particular aspect of emotional reactivity of the listener were assessed. Likewise, psychopathological aspects of personality were evaluated. A follow-up study compared 10 psychosomatic patients with a current depressive episode and/or personality disorder with distinct depressive symptoms and 10 age- and gender-matched healthy controls. METHODS Effects of narratives on listeners' mental state were tested with repeated-measures AN(C)OVA. Mediating effects in the listener (attachment characteristics in the context of personality traits) were explored. Narrative effects were compared between patients and controls. RESULTS Listening to insecure attachment narratives reduced well-being in controls. Nevertheless, tendency for social interaction was highest following the insecure-preoccupied narrative. Importantly, listeners' individual attachment characteristics mediated the relationship between well-being/interpersonal reactivity following the insecure-preoccupied narrative and levels of psychopathology. Furthermore, compared with healthy participants, patients showed higher emotional reactivity following exposure to the insecure-preoccupied narrative, represented by lower well-being and lower estimation of friendliness towards the narrator. CONCLUSIONS Exposure to attachment-specific speech patterns can result in dysphoric mood changes. Specifically, the insecure-preoccupied narrative influenced the listeners' emotional state, which was further mediated by the individual attachment patterns and psychopathological personality characteristics. This deepens the understanding of interpersonal processes, especially in psychotherapeutic settings. PRACTITIONER POINTS In clinical populations, insecure-preoccupied attachment has a high prevalence. In this study, listening to a narrative characteristic of insecure-preoccupied speech patterns resulted in reduced well-being in healthy listeners. Patients with depressive symptoms showed a higher emotional reactivity towards the insecure-preoccupied narrative compared to healthy controls. While working on (childhood) traumata, for example, in group therapy or inpatient settings, therapists should raise awareness to possible mood changes through discourse-conveyed attachment characteristics in listeners as a 'side effect'.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Peganum harmala Linn have been widely used for the treatment of nervous, cardiovascular, gastrointestinal, respiratory, and endocrine diseases and many other human ailments. However, tremor toxicity occurs after overdose and is tolerated following multiple dosing. Thus far, little is known about the underlying mechanisms of tremors and tremor tolerance. AIM OF THE STUDY To investigate the potential mechanisms of tremors and tremor tolerance induced in rats by the repeated administration of total alkaloid extracts from the seeds of P. harmala (TAEP). MATERIALS AND METHODS A tremor model was induced in male Wistar rats by administering TAEP at a dose of 150 mg/kg/day. To evaluate tremor action, behavioral assessment was conducted by using a custom-built tremor acquisition and analysis system. To investigate the relationships between tremors and neurotransmitter levels in the brain, various neurotransmitters were simultaneously quantified by an ultra-performance liquid chromatography combined with electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS) system, and the association between these two parameters was analyzed using Pearson correlation coefficients. To further elucidate the potential mechanisms of the alterations of neurotransmitter levels in cortical tissues, the protein expression levels of several important enzymes and transporters that are closely related to neurotransmitter levels were investigated. In addition, neuropathological analysis was conducted to assess the effect of TAEP on neurons in the brain. To further clarify the potential mechanisms of TAEP-induced neurodegeneration in the brain, c-fos was subjected to immunohistochemical analysis, and oxidative stress markers were examined. RESULTS Tremors initially occurred in rats after the oral administration of TAEP at a dose of 150 mg/kg/day. However, they were tolerated following repeated dosing. The levels of 5-hydroxytryptamine (5-HT) and glycine (Gly) in cortical tissues were most likely associated with the tremor response. Tremor tolerance also likely resulted from the degeneration of cerebellar Purkinje cells. Furthermore, the alteration of 5-HT levels was mainly attributed to the downregulated expression of monoamine oxidase A (MAO-A). The degeneration of Purkinje neurons might have resulted from the overexpression of c-fos and increased oxidative stress in the cerebellum after the multiple dosing of TAEP. CONCLUSION The tremor response induced by TAEP at high doses is closely related to the concentrations of 5-HT and Gly in cortical tissues. Tremor tolerance may also be attributed to the degeneration of cerebellar Purkinje cells after the repeated dosing of TAEP. Further studies should be conducted to elucidate the interaction of the alkaloids on the neurotransmitter receptors, the expression of related neurotransmitter receptors, the specific signaling pathway involved in regulating MAO-A, and the mechanism of the loss and functional recovery of cerebellar Purkinje neurons.

Abstract
The unprecedented pandemic of coronavirus disease 2019 (COVID-19) demands effective treatment for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The infection of SARS-CoV-2 critically depends on diverse viral or host proteases, which mediate viral entry, viral protein maturation, as well as the pathogenesis of the viral infection. Endogenous and exogenous agents targeting for proteases have been proved to be effective toward a variety of viral infections ranging from HIV to influenza virus, suggesting protease inhibitors as a promising antiviral treatment for COVID-19. In this Review, we discuss how host and viral proteases participated in the pathogenesis of COVID-19 as well as the prospects and ongoing clinical trials of protease inhibitors as treatments.

Abstract
Background and Objective:
Kang Fu Xin liquid (KFX) is an official preparation made from
the ethanol extract product from P. Americana. The present quality control method cannot control the
quality of the preparation well. The aim of the present study is to establish a convenient HPLC method
for multicomponents determination combined with fingerprint analysis for quality control of KFX.
Methods:
An HPLC-DAD method with gradient elution and detective wavelength switching program
was developed to establish HPLC fingerprints of KFX, and 38 batches of KFX were compared and
evaluated by similarity analysis (SA), hierarchical clustering analysis (HCA), and principal component
analysis (PCA). Meanwhile, six nucleosides and three amino acids, including uracil, hypoxanthine, uric
acid, adenosine, xanthine, inosine, tyrosine, phenylalanine and tryptophan in KFX were determined
based on the HPLC fingerprints.
Results:
An HPLC method assisted with gradient elution and wavelength switching program was established
and validated for multicomponents determination combined with fingerprint analysis of KFX.
The results demonstrated that the similarity values of the KFX samples were more than 0.845. PCA
indicated that peaks 4 (hypoxanthine), 7 (xanthine), 9 (tyrosine), 11, 13 and 17 might be the characteristic
contributed components. The nine constituents in KFX, uracil, hypoxanthine, uric acid, adenosine,
xanthine, inosine, tyrosine, phenylalanine and tryptophan, showed good regression (R2 > 0.9997) within
test ranges and the recoveries of the method for all analytes were in the range from 96.74 to 104.24%.
The limits of detections and quantifications for nine constituents in DAD were less than 0.22 and 0.43
μg•mL-1, respectively.
Conclusion:
The qualitative analysis of chemical fingerprints and the quantitative analysis of multiple
indicators provide a powerful and rational way to control the KFX quality for pharmaceutical companies.

Abstract
The aerial parts of Dracocephalum moldavica L. are extensively used in traditional ethnic medicines in China as a remedy for cardiovascular and cerebrovascular damage. However, the chemical composition and the accumulation of main secondary metabolites of D. moldavica in different natural environments remain unclear. This study aimed to conduct a qualitative and quantitative analysis of the main secondary metabolites to explore the quality variation of D. moldavica in markets. The evaluation of space-time accumulation of main secondary metabolites in D. moldavica was carried out during different growth periods and in different geographical locations. A total of 35 ingredients were detected and 24 identified, including 21 flavonoids, two phenolic acids and one coumarin by UPLC-QTOF-MS method. Furthermore, a simple and convenient HPLC method was successfully developed for the simultaneous determination of lutelin-7-O-glucuronide and tilianin and rosmarinic acid in D. moldavica. The results of space-time accumulation analysis showed the distinct variation of secondary metabolites of D. moldavica with the growth period and geographical location. Finally, the current study provided a meaningful and useful approach for comprehensively evaluating the quality of D. moldavica.

Abstract
Zanthoxylum nitidum (Roxb.) DC. (ZN) belongs to the genus Zanthoxylum of Rutaceae and has various chemical ingredients and pharmacologic effects. Alkaloids are its main active constituents responsible for diverse pharmacologic effects, such as anti-tumor, anti-bacterial, anti-inflammatory, and analgesic activities. The chemical and pharmacological effects of ZN are well reported, but the in vivo pharmacokinetic profiles of its main active alkaloids are poorly investigated. This study aims to elucidate the absorbed constituents and pharmacokinetic behavior of main active ingredients in rat plasma after the oral administration of ZN extract. The absorbed constituents in rat plasma were qualitatively analyzed using ultra-high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Ultra-high-performance liquid chromatography with triple quadrupole mass spectrometry (UPLC-MS/MS) method was developed for the simultaneous determination and pharmacokinetic studies of dihydrochelerythrine (DHCHE), nitidine chloride (NIT), chelerythrine (CHE), sanguinarine (SAN), liriodenine (LIR), skimmianine (SKI), γ-fagarine (FAG), and dictamnine (DIC) in rat plasma. Eighteen prototypes and metabolites were identified according to exact mass, characteristic diagnostic fragment ions, and reference standards. The established UPLC-MS/MS quantitative method met the requirements of FDA for biological analysis methods. Method validation showed that this method has good linearity (r ≥ 0.9910), precision (RSD ≤ 18.63 %), accuracy (88.11 %-117.50 %), and stability. The limit of detection (LOD) could reach 1 ng/mL, and the limit of quantitation could reach 2 ng/mL. The plasma drug concentration of benzophenanthridine alkaloids, such as NIT, CHE, and DHCHE, were still low even after dose differences were deducted. For the furan quinoline alkaloids (such as SKI, FAG, and DIC), only SKI showed high plasma drug concentration, although SKI content comprised only approximately 1/6 of benzophenanthridine alkaloids. This study is the first to simultaneously determine the above-mentioned active alkaloids in rat plasma and would contribute to the comprehensive understanding of in vivo pharmacokinetic behavior on active alkaloids in ZN extract.

Abstract
Harmine (HAR) is a β-carboline alkaloid with anti-inflammatory and antipruritic effect. However, the low bioavailability and side effects of HAR severely limited its clinical application. The main objective of this study was to develop harmine-loaded ethosomes (HLE) drug delivery system for topical application to treat inflammation. HLE were obtained by ethanol injection method and characterized. The morphology of HLE was evaluated by transmission electron microscopy (TEM). HLE exhibited a good biocompatibility with human embryonic skin fibroblasts and rat skin. The in vitro skin penetration studies showed that HLE had the greatest skin deposition than harmine-loaded liposomes (HLL) and harmine solution (HS). In vivo pharmacokinetic study demonstrated that AUC(0-∞) and Cmax of HLE in subcutaneous tissues were much higher than that of in blood. Moreover, for convenience of fixing on skin, HLE were mixed with gel. HLE gel significantly inhibited the overexpression of inflammation cytokines prostaglandin E2, interleuking (IL)-1β, nitric oxide, and tumor necrosis factor-alpha (TNF-α) in the inflammation model of rat paw edema compared with HS gel. In short, HLE was promising formulation for topical delivery in treatment of inflammatory diseases.

Abstract
Ulcerative colitis (UC) is usually accompanied with symptoms of abdominal pain, diarrhea, and bloody stool, which impair the quality of life of patients. Previous studies have shown that Andrographis paniculata extracts, which have andrographolide (AND) as their main compound, can relieve UC symptoms in patients. The aim of the study was to investigate the alleviating effect of AND on UC using the oxazolone (OXZ)-induced UC rat model. A total of 66 healthy male Sprague Dawley rats were used to evaluate the efficacy and mechanism of AND on UC (n = 11 per group) and grouped into control, model, SASP (sulfasalazine, positive control group, 500 mg/kg), AND-L (40 mg/kg), AND-M (80 mg/kg), and AND-H (120 mg/kg). The colonic disease activity index (DAI), colon length, spleen coefficient, pathological damage, and inflammation-related cytokine and protein expression levels were used as indices for evaluation. Results showed that the AND groups had reduced DAI and mortality, and significantly improved colon length and spleen coefficient compared with the model group. Furthermore, OXZ-induced histological injury was relieved significantly after AND treatment due to an improved crypt structure and reduced infiltration of inflammatory cells. Moreover, AND inhibited myeloperoxidase (MPO) activity and the secretion of interleukin-4 (IL-4), IL-13, and tumor necrosis factor α (TNF-α). The results of the anti-inflammatory mechanism revealed that AND blocked the signal transduction by reducing IL-4/IL-13 specific binding to IL-4 receptor (IL-4R) and inhibiting the phosphorylation of the signal transducer and activator of transcription 6 (p-STAT6). In conclusion, aside from natural plants, AND may be a candidate ingredient for UC therapy.

Abstract
We report on the investigation on the transverse effect of superradiation (SR) in Rb atomic medium by analyzing and comparing the diffraction patterns in the far-field under the circumstances that Gaussian and Bessel beam are taken as the excitation respectively. It is found that Gaussian SR shows a ring-pattern and its beam profile is closely dependent on the incident power and position of the sample cell. The experimental results are in good agreement with the simulations using semi-classical theory of SR together with spatial self-phase modulation (SPM), indicating that the transverse effect of SR is mainly attributed to its propagation in the nonlinear medium. By contrast, the beam profile of Bessel SR is hardly influenced by the input power thanks to its non-diffraction property. The comparison further confirms that the transverse effect of the SR is the result of the nonlinear effect for SR. This work provides useful information in understanding the physics behind the transverse effect of SR, which would be of significance in the applications of SR, such as enhancement on the beam quality and efficiency of the SR sources.

Abstract
INTRODUCTION Patient-reported outcome-based symptom monitoring and alerting have been attractive for patient care after a tumour-removal surgery. However, the implementation parameters of this patient-centred symptom management system in perioperative patients with lung cancer are still lacking. We aim to develop a perioperative symptom scale (PSS) for monitoring, to determine the optimal time points for symptom assessment and to define the alert thresholds for medical intervention. METHODS AND ANALYSIS This study will prospectively recruit 300 patients undergoing lung cancer surgery in six hospitals. The MD Anderson Symptom Inventory-Lung Cancer Module (MDASI-LC) is used to collect longitudinal symptom data preoperatively, daily postoperatively during in-hospital stay and weekly after discharge until 4 weeks or the start of postoperative oncological therapy. Symptoms that change significantly over time will be generated as the PSS. We will determine the optimal time points for follow-up using the generalised linear mixed-effects models. The MDASI-LC interference-measured functional status will be used as the anchor for the alert thresholds. ETHICS AND DISSEMINATION Ethics Committee of Sichuan Cancer Hospital approved this study on 16 October 2017 (No. SCCHEC-02-2017-042). The manuscript is based on the latest protocol of Version 3.0, 15 September 2019. The results of this study will be presented at medical conferences and published in peer-reviewed journals.

Abstract
We report on the study of the thermally induced nonlinear optical (NLO) properties of the commonly used organic solvents at the near-infrared range using spatial cross-phase modulation (SXPM). The results indicate that those solvents (alcohols, formic acid, and acetic acid) with -OH and -COOH functional groups have obvious NLO effect in the near-infrared range due to the third overtone absorption of the O-H band. In addition, the NLO effect of the ketones and aldehydes is enhanced when water or nitric acid is added, because the products with -OH and -COOH are generated, respectively, according to the nucleophilic addition reactions. Finally, real-time visualization of the acetone nucleophilic addition reaction is realized by monitoring the SXPM diffraction patterns' variation with time. This work not only is of importance in studying the NLO properties of the materials, e.g, interpreting the results performed in solutions and selecting suitable solvents, but also provides a simple way to visualize chemical reactions.

Abstract
BACKGROUND Aerial parts of Peganum harmala Linn is used as a traditional medical herb for treatment of amnesia in Uighur medicine in China. Deoxyvasicine (DVAS) is one of the chief active ingredients in P. harmala, it possesses strong acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities in vitro, but the therapeutic effect and mechanisms on amnesia in vivo are unclear. PURPOSE The objective of this study was to investigate the improvement effect of DVAS from P. harmala in learning and memory deficits of scopolamine-induced mice and elucidate the underlying mechanisms involved. METHODS Mice were pretreated with DVAS (5, 15 and 45 mg/kg) and huperzine-A (0.2 mg/kg) by gavage for 7 days, and subsequently were daily intraperitoneally injected with scopolamine (1 mg/kg) to induce learning and memory deficits and behavioral performance was assessed by Morris water maze. To further evaluate the potential mechanisms of DVAS in improving learning and memory capabilities, pathological change, levels of various biochemical markers and protein expressions related to cholinergic system, oxidative stress, and neuroinflammation were examined. RESULTS The results showed that DVAS could alleviate learning and memory deficits in scopolamine-treated mice. DVAS could regulate cholinergic function by inhibiting AChE and activating choline acetyltransferase (ChAT) activities and protein expressions. DVAS could induce brain-derived neurotrophic factor and protect hippocampal pyramidal cells against neuronal damage. DVAS also enhanced antioxidant defense via increasing the antioxidant enzyme level and activity of glutathione peroxidase, and anti-inflammatory function through suppressing tumor necrosis factor-α. Additionally, DVAS could regulate the neurotransmitters by elevating acetylcholine, 5-hydroxytryptamine, γ-aminobutyric acid and reducing 5-hydroxyindole-3-acetic acid and glutamic acid. CONCLUSION Results illustrated that DVAS may be a promising candidate compound against amnesia via restoration of cholinergic function, regulating neurotransmitters, attenuating neuroinflammation and oxidative stress.

Abstract
The challenges in achieving a green and scalable integration of two-dimensional (2D) materials with flexible polymer substrates present a major barrier for the application of 2D materials, such as graphene, MoS2, and h-BN for flexible devices. Here, we create a sono-assisted surface energy driven assembly (SASEDA) method that can achieve foot-scale to micrometer-scale assembly of 2D materials, form a conductive network in as short as 10 s, and build hierarchical and hybrid flexible devices such as sensors, resistors, and capacitors by using water as the dispersion solvent. SASEDA highlights two counterintuitive innovations. First, we use an "unfavorable" solvent (i.e., water) for both 2D materials (e.g., graphene, MoS2, and h-BN) and polymer substrates (e.g., polydimethylsiloxane) to drive the assembly process. Second, we use a weak sono-field (0.3 W/cm2) generated by a regular sonication bath cleaner to enhance the assembly efficiency and reorganize and unify the assembly network. This method and its principle pave the way toward affordable large-scale 2D material-based flexible devices.

Abstract
BACKGROUND β-Carboline alkaloid harmine (HAR) and harmaline (HAL) are monoamine oxidase (MAO) and acetylcholinesterase (AChE) inhibitors. However, whether HAR and HAL inhibit MAO or AChE selectively and competitively is unclear. PURPOSE The purpose of this study was to investigate the potential competition inhibition of HAR and HAL on MAO and AChE in brain endothelial cells (RBE4) and in healthy rats to provide a basis for the application of the inhibitors in the treatment of patients with depression and with Parkinson's disease or Alzheimer's disease. STUDY DESIGN/METHODS The transport properties of HAR and HAL by using blood-brain barrier models constructed with RBE4 were systematically investigated. Then, the modulation effects of HAR and HAL on CNS neurotransmitters (NTs) in healthy rat brains were determined by a microdialysis method coupled with LC-MS/MS. The competition inhibition of HAR and HAL on MAO and AChE was evaluated through real time-PCR, Western blot analysis, and molecular docking experiments. RESULTS Results showed that HAL and HAR can be detected in the blood and striatum 300 min after intravenous injection (1 mg/kg). Choline (Ch), gamma-aminobutyric acid (GABA), glutamate (Glu), and phenylalanine (Phe) levels in the striatum decreased in a time-dependent manner after the HAL treatment, with average velocities of 1.41, 0.73, 3.86, and 1.10 (ng/ml)/min, respectively. The Ch and GABA levels in the striatum decreased after the HAR treatment, with average velocities of 1.16 and 0.22 ng/ml/min, respectively. The results of the cocktail experiment using the human liver enzyme indicated that the IC50 value of HAL on MAO-A was 0.10 ± 0.08 µm and that of HAR was 0.38 ± 0.21 µm. Their IC50 values on AChE were not obtained. These findings indicated that HAL and HAR selectively acted on MAO in vitro. However, RT-PCR and Western blot analysis results showed that the AChE mRNA and protein expression decreased in a time-dependent manner in RBE4 cells after the HAR and HAL treatments. CONCLUSION NT analysis results showed that HAL and HAR selectively affect AChE in vivo. HAL and HAR may be highly and suitably developed for the treatment of Alzheimer's disease.

Abstract
Traditionally, pomegranate (Punica granatum L.) has been consumed as fresh fruit or as pomegranate juice. Pomegranate peel, the dried husk of P· granatum, is an important herbal medicine for treating diarrhea, hemostasis and insect-induced abdominal pain in China. However, the quality control methods for pomegranate peel remain unsatisfactory. In this work, a new HPLC-based qualitative and quantitative method for quality control of pomegranate peel was developed and validated for the simultaneous determination of polyphenols and triterpenes (including punicalagins A and B, ellagic acid, oleanolic acid and ursolic acid) by solvent extraction and ratio blending method in tandem with wavelength switching. The average recoveries were 98.07-100.61% with relative standard deviation no more than 4.27%. In addition, the fingerprint analysis was conducted to interpret the consistency of the quality test. Thirteen characteristic peaks were selected to evaluate the similarities of 16 batches of pomegranate peel. The similarities of samples were all more than 0.80, indicating that the samples from different areas of China were consistent. The results demonstrated that quantitative analysis and the HPLC fingerprint as a characteristic distinguishing method combining similarity evaluation can be successfully used to assess the quality and to identify the authenticity of pomegranate peel.
