RESUMEN

Objective: The objective of this study was to investigate the transition readiness of juvenile epilepsy patients during the transition period from childhood to adulthood and analyze the impact of patients' basic characteristics and self-management on their transition readiness. Methods: A total of 376 adolescent epileptic patients were selected as research objects from 3A general hospitals located in Chongqing, Guizhou, and Yunnan respectively, and a 3A children's specialist hospital in Chongqing, Jiangxi from May 2021 to February 2022. The readiness for transition was assessed using a transition readiness questionnaire, and patients' self-management skills were evaluated using the Self-Management Scale for Epilepsy Patients. Data analysis was conducted to determine the readiness for transition and examine the factors influencing it. Results: The mean overall transition readiness score in adolescent epilepsy patients was (56.60±12.51). Among the six dimensions, drug management, disease understanding, doctor-patient interaction, health responsibility, medical involvement, and resource utilization were ranked highest to lowest. The examination identified age, epilepsy duration, medication types, and primary caregivers as the primary factors influencing transition readiness in adolescent epilepsy patients (P < .001). Additionally, there was a favorable correlation between the total disease self-management score and transition readiness (r=0.487, P < .01), signifying the positive predictive impact of self-management skills on transition readiness. Conclusion: Adolescent epilepsy patients exhibited moderate readiness for the transition from childhood to adulthood. Older patients with longer disease duration and stronger self-management skills displayed a higher level of readiness. Targeted clinical interventions that prioritize self-management skills are essential for facilitating a smoother transition into adulthood for patients.

RESUMEN

The stability of microbial communities, especially among core taxa, is essential for supporting plant health. However, the impacts of disease infection on the stability of rhizosphere fungal core microbiome remain largely unexplored. In this study, we delved into the effects of root rot infestation on the community structure, function, network complexity, and stability of Sanqi fungal core microbiomes, employing amplicon sequencing combined with co-occurrence network and cohesion analyses. Our investigation revealed that root rot disease led to a decrease in the α-diversity but an increase in the ß-diversity of the Sanqi fungal core microbiomes in the rhizosphere. Notably, Ilyonectria, Plectosphaerella, and Fusarium emerged as indicator species in the rhizosphere core microbiome of root rot-infected Sanqi plants, while Mortierella predominated as the dominant biomarker taxa in healthy soils. Additionally, root rot diminished the complexity and modularity of the rhizosphere networks by reducing the metrics associated with nodes, edges, degrees, and modularity. Furthermore, root rot resulted in a reduction in the proportion of negative connections in the network and the negative/positive cohesion of the entire core fungal microbiome. Particularly noteworthy was the observation that root rot infection destabilized the rhizosphere core fungal microbiome by weakening the negative connectivity associated with beneficial agents. Collectively, these results highlight the significance of the negative connectivity of beneficial agents in ensuring the stability of core microbial community.IMPORTANCERoot rot disease has been reported as the most devastating disease in the production process of artificial cultivated Sanqi ginseng, which seriously threatens the Sanqi industry. This study provides valuable insights into how root rot influences microbial relationships within the community. These findings open up opportunities for disease prevention and the promotion of plant health by regulating microbial interactions. In summary, the research sheds light on the ecological consequences of root rot on rhizosphere fungal microbiomes and offers potential strategies for managing soil-borne diseases and enhancing plant health.

RESUMEN

BACKGROUND: The addition of immune checkpoint inhibitors to neoadjuvant chemotherapy in operable advanced gastric or gastroesophageal junction (G/GEJ) cancer aroused wide interest. This study was designed to assess the efficacy and safety of neoadjuvant sintilimab, a programmed cell death protein-1 (PD-1) inhibitor, in combination with fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy for HER2-negative locally advanced G/GEJ cancer. METHODS: Eligible patients with clinical stage cT4 and/or cN+M0 G/GEJ cancer were enroled in this phase II study. Patients received neoadjuvant sintilimab (200 mg every 3 weeks) for three cycles plus FLOT (50 mg/m 2 docetaxel, 80 mg/m 2 oxaliplatin, 200 mg/m 2 calcium levofolinate, 2600 mg/m 2 5-fluorouracil every 2 weeks) for four cycles before surgery, followed by four cycles of adjuvant FLOT with same dosages after resection. The primary endpoint was the pathological complete response (pCR) rate. RESULTS: Thirty-two patients were enroled between August 2019 and September 2021, with a median follow-up of 34.8 (95% CI, 32.8-42.9) months. Thirty-two (100%) patients received neoadjuvant therapy, and 29 underwent surgery with an R0 resection rate of 93.1%. The pCR (TRG0) was achieved in 5 (17.2%; 95% CI, 5.8-35.8%) patients, and the major pathological response was 55.2%. Twenty-three (79.3%) patients had T downstaging, 21 (72.4%) had N downstaging, and 19 (65.5%) had overall TNM downstaging. Six (20.7%) patients experienced recurrence. Patients achieving pCR showed better event-free survival (EFS), disease-free survival (DFS), and overall survival (OS) than non-pCR. The estimated 3-year EFS rate, 3-year DFS rate, and 3-year OS rate were 71.4% (95% CI, 57.2-89.2%), 78.8% (95% CI, 65.1-95.5%), and 70.9% (95% CI, 54.8-91.6%), respectively. The objective response rate and disease control rate were 84.4% (95% CI, 68.3-93.1%) and 96.9% (95% CI, 84.3-99.5%), respectively. Twenty-five (86.2%) received adjuvant therapy. The main grade ≥3 treatment-related adverse events (TRAEs) were lymphopenia (34.4%), neutropenia (28.1%), and leukopenia (15.6%). no patients died from TRAE. The LDH level exhibited a better predictive value to pathological responses than PD-L1 and MSI status. CONCLUSIONS: The study demonstrated an encouraging efficacy and manageable safety profile of neoadjuvant sintilimab plus FLOT in HER2-negative locally advanced G/GEJ cancer, which suggested a potential therapeutic option for this population.

RESUMEN

Conventional transnasal brain-targeted drug delivery strategies are limited by nasal cilia clearance and the nasal mucosal barrier. To address this challenge, we designed dissolving microneedles combined with nanocarriers for enhanced nose-to-brain drug delivery. To facilitate transnasal administration, a toothbrush-like microneedle patch was fabricated with hyaluronic acid-formed microneedles and tannic acid-crosslinked gelatin as the base, which completely dissolved in the nasal mucosa within seconds leaving only the base, thereby releasing the loaded cyclodextrin-based metal-organic frameworks (CD-MOFs) without affecting the nasal cilia and nasal microbial communities. As nanocarriers for high loading of huperzine A, these potassium-structured CD-MOFs, reinforced with stigmasterol and functionalized with lactoferrin, possessed improved physical stability and excellent biocompatibility, enabling efficient brain-targeted drug delivery. This delivery system substantially attenuated H2O2- and scopolamine-induced neurocyte damage. The efficacy of huperzine A on scopolamine- and D-galactose & AlCl3-induced memory deficits in rats was significantly improved, as evidenced by inhibiting acetylcholinesterase activity, alleviating oxidative stress damage in the brain, and improving learning function, meanwhile activating extracellular regulated protein kinases-cyclic AMP responsive element binding protein-brain derived neurotrophic factor pathway. Moreover, postsynaptic density protein PSD-95, which interacts with two important therapeutic targets Tau and ß-amyloid in Alzheimer's disease, was upregulated. This fruitful treatment was further shown to significantly ameliorate Tau hyperphosphorylation and decrease ß-amyloid by ways including modulating beta-site amyloid precursor protein cleaving enzyme 1 and a disintegrin and metalloproteinase 10. Collectively, such a newly developed strategy breaks the impasse for efficient drug delivery to the brain, and the potential therapeutic role of huperzine A for Alzheimer's disease is further illustrated.

RESUMEN

Narcissin is a natural flavonoid from some edible and traditional medicinal plants. It has been proven to have multiple biological functions and exhibits potential therapeutic effects on hypertension, cancer, and Alzheimer's disease. However, the toxicity of narcissin is largely unknown. Here, we revealed that narcissin treatment led to reduced hatchability, increased malformation rate, shorter body length, and slowed blood flow in zebrafish. Furthermore, bradycardia, pericardial edema, increased SV-BA distance, diminished stroke volume, ejection fraction, and ventricular short-axis shortening rate were also found. A large accumulation of ROS, increased apoptotic cells, and histopathological changes were detected in the heart region. Moreover, the gene expression profiles and molecular docking analysis indicated that Nrf2/HO-1 and calcium signaling pathways were involved in narcissin-induced toxicity. In conclusion, here we provide the first evidence that demonstrates narcissin-induced developmental toxicity and cardiotoxicity in zebrafish via Nrf2/HO-1 and calcium signaling pathways for the first time.

RESUMEN

Pathological pain, a multifaceted and debilitating ailment originating from injury or post-injury inflammation of the somatosensory system, poses a global health challenge. Despite its ubiquity, reliable therapeutic strategies remain elusive. To solve this problem, resveratrol, a naturally occurring nonflavonoid polyphenol, has emerged as a potential beacon of hope owing to its anti-inflammatory, antioxidant, and immunomodulatory capabilities. These properties potentially position resveratrol as an efficacious candidate for the management of pathological pain. This concise review summaries current experimental and clinical findings to underscore the therapeutic potential of resveratrol in pathological pain, casting light on the complex underlying pathophysiology. Our exploration suggests that resveratrol may exert its analgesic effect by the modulating pivotal signaling pathways, including PI3K/Akt/mTOR, TNFR1/NF-κB, MAPKs, and Nrf2. Moreover, resveratrol appears to attenuate spinal microglia activation, regulate primary receptors in dorsal root sensory neurons, inhibit pertinent voltage-gated ion channels, and curb the expression of inflammatory mediators and oxidative stress responses. The objective of this review is to encapsulate the pharmacological activity of resveratrol, including its probable signaling pathways, pharmacokinetics, and toxicology pertinent to the treatment of pathological pain. Hopefully, we aim to map out promising trajectories for the development of resveratrol as a potential analgesic.

RESUMEN

Hepatocellular carcinoma (HCC), ranking as the seventh most prevalent cancer worldwide, poses a significant health challenge. Actinidia chinensis Planch Root extracts (acRoots), a traditional Chinese medicine, has exhibited promising inhibitory effects on the proliferation, invasion, and migration of various cancer cell types. Nevertheless, its specific impact and underlying mechanisms concerning HCC remain unclear. This research aimed to elucidate the anticancer properties and potential molecular mechanisms of acRoots in the HepG2 and LM3 cell lines. Our findings demonstrate that acRoots effectively hampers the in vitro proliferation, migration, and invasion of HCC cells. Furthermore, acRoots induces apoptosis and autophagy by impeding the AKT/mTOR signaling pathway, with its inhibitory effects on cells being restored under AKT activator induction. This study, for the first time, elucidates that acRoots can suppress HepG2 and LM3 cell proliferation by blocking the Akt/mTOR pathway, thereby activating apoptosis and autophagy. These results underscore the potential of acRoots as a promising antitumor agent for HCC.

RESUMEN

An integrated anaerobic digestion system for the simultaneous removal of carbon and nitrogen from fish sludge was developed by coupling iron sludge supplementation with intermittent aeration. In terms of nitrogen removal, Fe(III) in iron sludge could trigger Feammox reactions and intermittent aeration could drive the Fe(II)/Fe(III) cycle to sustain continuous ammonia removal. Mass balance analysis suggested that nitrate was the main product of Feammox, which was subsequently removed through heterotrophic denitrification. In terms of carbon removal, the Fe(III)-induced dissimilatory iron reduction (DIR) process significantly promoted fish sludge hydrolysis and provided more simple organics for methanogens and denitrifiers, but aeration showed a negative impact on methanogenesis. To promote nitrogen removal and avoid serious methanogenesis inhibition, different aeration intensities were studied. Results showed that compared with the control without aeration or iron sludge addition, aeration for 5 min every 3 days (150 mL/min) contributed to a 29.0% lower NH4+-N concentration and a 12.1% lower total chemical oxygen demand level on day 28, and the decline in methane yield was acceptable (only 13.5% lower). Simultaneous methanogenesis, Feammox, and denitrification in a single reactor treating fish sludge were achieved, which provides a simple and low-cost strategy for the treatment of organic wastewater.

RESUMEN

Continuous cultivation of medicinal plants can disrupt the rhizosphere's microbial community. There is still a need to know about the beneficial bacterial community, their putative drivers, and the potential functions they may have. This study used different growth years of Sanqi ginseng (Panax notoginseng) with root rot to look at the beneficial microbial community structure, the function of microbial carbon source utilization, and the function of rhizosphere soil metabolism. The beneficial bacterial community changed and the relative abundance of beneficial agents was suppressed significantly with the successive Sanqi ginseng plantings. The carbon source utilization capacity and diversity increased significantly, whereas three autotoxin degradation-related pathways (biosynthesis of other secondary metabolites, metabolism of terpenoids and polyketides, and xenobiotics biodegradation and metabolism) were downregulated considerably with planting year extended. The changes in the beneficial agents were driven by the shifts in phenolic acid profiles, and the decline of beneficial microbes led to the loss of microbial autotoxin degradation functions. Overall, these results provide insight into beneficial microbes, microbial functions, phenolic acids, and their interactions, and these findings are essential for maintaining healthy and sustainable cultivation of Sanqi ginseng. IMPORTANCE Sanqi ginseng is a valuable perennial Chinese herb with various benefits for human health. However, continuous cultivation causes a high incidence of root rot disease, which leads to decreased yield and serious economic losses and ultimately impedes the sustainable development of Chinese medicine production. The significance of this study is to reveal the pattern of changes in beneficial bacteria and their related functions in root rot diseased rhizosphere with the successive planting years of Sanqi ginseng. This study found that the decline of beneficial bacterial agents mediated by phenolic acid profiles appears to be associated with the loss of microbial autotoxin degradation functions. This result may have new implications for deciphering the causes of Sanqi ginseng's continuous cropping obstacles.

RESUMEN

Significance: Skin is the largest organ and also the first barrier of body. Skin diseases are common, and cutaneous microcirculation is relative to various diseases. Researchers attempt to develop novel imaging techniques to obtain the complex structure, components, and functions of skin. Modern optical techniques provide a powerful tool with non-invasiveness, but the imaging performance suffers from the turbid character of skin. In vivo skin optical clearing technique has been proposed to reduce tissue scattering and enhance penetration depth of light and became a hot topic of research. Aim: The aim of this review is to provide a comprehensive overview of recent development of in vivo skin optical clearing methods, how in vivo skin optical clearing enhances imaging performance, and its applications in study and light therapy of various diseases. Approach: Based on the references published over the last decade, the important milestones on the mechanism, methods, and its fundamental and clinical applications of in vivo skin optical clearing technique are provided. Results: With the deepening understanding of skin optical clearing mechanisms, efficient in vivo skin optical clearing methods were constantly screened out. These methods have been combined with various optical imaging techniques to improve imaging performances and acquire deeper and finer skin-related information. In addition, in vivo skin optical clearing technique has been widely applied in assisting study of diseases as well as achieving safe, high-efficiency light-induced therapy. Conclusions: In the last decade, in vivo skin optical clearing technique has developed rapidly and played an important role in skin-related studies.

RESUMEN

The immunomodulatory effect of Saposhnikoviae Radix polysaccharide(SRP) was evaluated based on the zebrafish mo-del, and its mechanism was explored by transcriptome sequencing and real-time fluorescence-based quantitative PCR(RT-qPCR). The immune-compromised model was induced by navelbine in the immunofluorescence-labeled transgenic zebrafish Tg(lyz: DsRed), and the effect of SRP on the density and distribution of macrophages in zebrafish was evaluated. The effect of SRP on the numbers of macrophages and neutrophils in wild-type AB zebrafish was detected by neutral red and Sudan black B staining. The content of NO in zebrafish was detected by DAF-FM DA fluorescence probe. The content of IL-1ß and IL-6 in zebrafish was detected by ELISA. The differentially expressed genes(DEGs) of zebrafish in the blank control group, the model group, and the SRP treatment group were analyzed by transcriptome sequencing. The immune regulation mechanism was analyzed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment, and the expression levels of key genes were verified by RT-qPCR. The results showed that SRP could significantly increase the density of immune cells in zebrafish, increase the number of macrophages and neutrophils, and reduce the content of NO, IL-1ß, and IL-6 in immune-compromised zebrafish. The results of transcriptome sequencing analysis showed that SRP could affect the expression level of immune-related genes on Toll-like receptor pathway and herpes simplex infection pathway to affect the release of downstream cytokines and interferon, thereby completing the activation process of T cells and playing a role in regulating the immune activity of the body.

RESUMEN

Free-falling cubic Test Masses (TMs) are a key component of the interferometer used for low-frequency gravitational wave (GW) detection in space. However, exposure to energetic particles in the environment can lead to electrostatic charging of the TM, resulting in additional electrostatic and Lorentz forces that can impact GW detection sensitivity. To evaluate this effect, the high-energy proton data set of the Geostationary Operational Environmental Satellite (GOES) program was used to analyze TM charging due to Solar Proton Events (SPEs) in the 24th solar cycle. Using the Geant4 Monte Carlo toolkit, the TM charging process is simulated in a space environment for SPEs falling into three ranges of proton flux: (1) greater than 10 pfu and less than 100 pfu, (2) greater than 100 pfu and less than 1000 pfu, and (3) greater than 1000 pfu. It is found that SPEs charging can reach the threshold within 535 s to 18.6 h, considering a reasonable discharge threshold of LISA and Taiji. We demonstrate that while there is a somewhat linear correlation between the net charging rate of the TM and the integrated flux of [Formula: see text] 10 MeV SPEs, there are many cases in which the integrated flux is significantly different from the charging rate. Therefore, we investigate the difference between the integral flux and the charging rate of SPEs using the charging efficiency assessment method. Our results indicate that the energy spectrum structure of SPEs is the most important factor influencing the charging rate. Lastly, we evaluate the charging probability of SPEs in the 24th solar cycle and find that the frequency and charging risk of SPEs are highest in the 3rd, 4th, 5th, 6th, and 7th years, which can serve as a reference for future GW detection spacecraft.

RESUMEN

Tumor multidrug resistance (MDR) remains one of the most challenging barriers to successful cancer treatment. Several previous studies have suggested that high mobility group box 1 (HMGB1) may be a promising therapeutic target for overcoming cancer drug resistance. Emerging evidence has indicated that HMGB1 functions as a 'double­edged sword' that plays both pro­ and anti­tumor roles in the development and progression of multiple types of cancer. HMGB1 has also been found to be a key regulator of several cell death and signaling pathways, and is involved in MDR by mediating cell autophagy and apoptosis, ferroptosis, pyroptosis and multiple signaling pathways. Additionally, HMGB1 is regulated by a variety of non­coding RNAs (ncRNAs), such as microRNAs, long ncRNAs and circular RNAs that are involved in MDR. Thus far, studies have been conducted to identify strategies with which to overcome HMGB1­mediated MDR by the targeted silencing of HMGB1 and the targeted interference of HMGB1 expression using drugs and ncRNAs. Therefore, HMGB1 is closely associated with tumor MDR and is a promising therapeutic target.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Angiogenesis is particularly important in ischemic cardiovascular diseases such as coronary heart disease (CHD). Xinkeshu tablets (XKS) are a commonly used Chinese patent medicine for CHD with a defined clinical effect. However, the proangiogenic effect of XKS remains unknown. AIM OF THE STUDY: We attempted to investigate the chemical composition and proangiogenic effect of XKS, as well as its underlying mechanisms. MATERIALS AND METHODS: The chemical composition of a XKS methanol extract was analyzed using a UPLC-Q-Orbitrap-MS system. The compound's proangiogenic effects were evaluated in zebrafish embryos and human umbilical vein endothelial cells (HUVECs). Furthermore, the underlying mechanisms were investigated using transcriptome assays and real-time quantitative PCR validation. RESULTS: We identified 116 chemical constituents of XKS. XKS significantly stimulated subintestinal vessel plexus (SIVs) growth and rescued tyrosine kinase inhibitor (PTK787)-induced intersegmental vessels (ISVs) injury in zebrafish in a concentration-dependent manner. XKS significantly rescued the proliferation, migration capacity and tube formation of Recombinant VEGFR tyrosine kinase inhibitor II (VRI)-injured HUVECs. XKS promoted angiogenesis through multiple signaling pathways, including metabolic pathways, the PPAR signaling pathway, the AGE-RAGE signaling pathway, the NOD-like receptor signaling pathway, the VEGF signaling pathway, and the PI3K/Akt signaling pathway. CONCLUSION: Herein, we identified 116 chemical constituents of XKS for the first time and demonstrated that XKS may regulate angiogenesis through multiple signaling pathways to treat CHD.

RESUMEN

Anthocyanins and selenium (Se) play critical roles in antioxidant, anticancer, antibacterial, and antiviral treatments. Previous studies indicate that colored-grain wheat accumulates more Se than regular wheat, and Se synergistically promotes anthocyanin synthesis. However, the mechanism through which Se regulates anthocyanin synthesis remains unclear. We studied anthocyanin accumulation during the grain-filling stage of colored-grain wheat development by employing transcriptomics and metabolomics. We show that Se biofortification increased the concentrations of Se, anthocyanin, chlorophyll a and b, and carotenoids in colored-grain wheat. Genes related to biosynthesis of anthocyanins, phenylpropanoids biosynthesis, and flavonoids biosynthesis were significantly upregulated after Se treatment, which led to the accumulation of anthocyanin metabolites in colored-grain wheat. Genetic alterations in the expression profiles of several genes and transcription factors were observed, which slowed down lignin and proanthocyanidin biosynthesis and accelerated anthocyanin synthesis. Our results deepen the understanding of anthocyanin metabolism in Se-treated colored-grain wheat, which will likely promote harvest of these varieties.

RESUMEN

Diabetic nephropathy (DN) is the most important cause of chronic renal and end-stage kidney disease in China. Hypertension (HTN) is highly prevalent in individuals with diabetic nephropathy. Arterial HTN affects two-thirds of people with type 2 diabetes (T2D). In these patients, HTN increased the potential of both micro- and macrovascular complications, and the co-occurrence of 2 such principal causes results in a 4-fold increased risk for cardiovascular disease (CVD) when contrasted with normotensive controls without diabetes. Therefore, the results of valsartan and amlodipine tablets combined with alpha-lipoic acid on total antioxidant capacity (T-AOC) need to be investigated. The aim of this study was to analyze the effects of valsartan (VA) and amlodipine tablets combined with alpha-lipoic acid (α-LA) on T-AOC, IL-6 and ß2-MG levels in patients with DN. We performed statistical analysis including the chi-square test, independent t-test, paired t-test and Analysis of Variance (ANOVA). Our findings indicate that VA, amlodipine and α-LA has a significant effect in patients with DN.

RESUMEN

BACKGROUND: Evidence suggests that Dachengqi and its modified decoctions are effective for treating abdominal pain, multiple organ dysfunction syndrome (MODS) and inflammation in various disease conditions. We performed a meta-analysis to ascertain the effectiveness of a series of chengqi decoctions in patients with severe acute pancreatitis (SAP). METHODS: We searched Pubmed, Embase, Cochrane library, Web of Science, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature, Wanfang database and China Science and Technology Journal Database before August 2022 to identify eligible randomized controlled trials (RCTs). Mortality and MODS were chosen as primary outcomes. Secondary outcomes included time until relief of abdominal pain, APACHE II score, complications, effectiveness, IL-6 and TNF-α levels. The risk ratio (RR) and standardized mean difference (SMD) with a 95% confidence interval (CI) were selected as effect measures. The quality of evidence was independently assessed by two reviewers using Grading of Recommendations Assessment Development and Evaluation (GRADE) system. RESULTS: Twenty-three RCTs (n = 1865) were finally included. The results showed that, compared with routine therapies, chengqi-series decoctions (CQSDs) treatment groups were associated with lower mortality rate (RR: 0.41, 95%CI: 0.32 to 0.53, p = 0.992) and incidence of MODS (RR: 0.48, 95%CI: 0.36 to 0.63, p = 0.885). They also reduced remission time of abdominal pain (SMD: -1.66, 95%CI: -1.98 to -1.35, p = 0.000), complications (RR: 0.52, 95%CI: 0.39 to 0.68, p = 0.716), APACHE II score (SMD: -1.04, 95%CI:-1.55 to -0.54, p = 0.003), IL-6 (SMD: -1.5, 95%CI: -2.16 to -0.85, p = 0.000), TNF-α (SMD: -1.18, 95%CI: -1.71 to -0.65, p = 0.000), and improved curative effectiveness (RR:1.22, 95%CI: 1.14 to 1.31, p = 0.757). The certainty of the evidence for these outcomes was low to moderate. CONCLUSION: CQSDs seem to be effective therapy for SAP patients with notable reductions in mortality, MODS and abdominal pain, with low quality evidence. Large-scale, multi-center RCTs that are more meticulous are advised in order to produce superior evidence.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Scutellaria baicalensis (SB) is a traditional Chinese medicine (TCM). In the clinical application of TCM, SB has been divided into two specifications (Ziqin and Kuqin) for a long time. At present, the Chinese Pharmacopoeia Commission no longer distinguishes between the two. However, the two specifications of medicinal materials and pieces are still in circulation in the market. AIM OF THE STUDY: This work aimed at investigating the similarities and differences between Ziqin and Kuqin in anti-inflammatory, analgesic, and antioxidant activities and their material basis. It will provide a new angle for relevant regulations to formulate the specifications and standards of SB. MATERIALS AND METHODS: Here we investigated the similarities and differences between Ziqin and Kuqin in anti-inflammatory, analgesic, and antioxidant activities related to four zebrafish models and three chemical tests. The chemical fingerprints of SB (Ziqin and Kuqin) were profiled by HPLC. Meanwhile, UHPLC-Q-TOF/MS was used to identify the chemical constituents of Ziqin and Kuqin. The main effect-related compounds of SB, Ziqin, and Kuqin were screened out by spectrum-effect relationship. Finally, six monomeric compounds were validated experimentally using the zebrafish inflammation model induced by CuSO4. RESULTS: Both Ziqin and Kuqin had significant anti-inflammatory, analgesic, and antioxidant activities. Kuqin had better anti-inflammatory and analgesic activities, while Ziqin had better antioxidant activity. HPLC fingerprint and UHPLC-Q-TOF/MS evaluation showed that the chemical composition types and main components of Ziqin and Kuqin were basically the same, while the contents and proportions of chemical components in Ziqin and Kuqin were different. By spectrum-effect relationship, compounds X1, X2 (luteoloside), X3, X4 (baicalin), X6 (wogonoside), X7 (baicalein), X8 (wogonin), and X9 (oroxylin A) were the same active chemical constituents of Ziqin and Kuqin. The core components of anti-inflammatory and analgesia activities in Kuqin were compounds X1, X2, X3, X5, X6, X7, X8, and X9. The antioxidant core active components of Ziqin were compounds X2, X3, X4, X6, X7, and X9. Among them, luteoloside, baicalin, wogonoside, baicalein, wogonin, and oroxylin A were validated successfully with good anti-inflammatory effects. CONCLUSIONS: This study revealed that Ziqin and kuqin have high similarity in chemical composition, but their proportions and active core components are different. This may be one of the main reasons why they have the same activity but different activity trends. These findings will help to improve the understanding of the different clinical applications of Ziqin and Kuqin, and provide a reference for the formulation of quality standards and their further research.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Artemisia vestita Wall. ex Besser is wildly distributed in the western high-altitude area of China and has been used as a Tibetan medicine to treat inflammatory diseases. We previously demonstrated the total flavonoids of Artemisia vestita Wall. ex Besser (TFA) showed obvious anti-inflammatory effects and its content was 276.62 mg/g. However, the chemical profile, active ingredients, and anti-inflammatory mechanisms of TFA are not clear. AIM OF THE STUDY: This study aimed to study the components of TFA, evaluate the anti-inflammatory effects of TFA, and preliminarily predict the anti-inflammatory mechanism of TFA. MATERIALS AND METHODS: TFA was prepared by the semi-biomimetic extraction method and purified by macroporous resin. The components of TFA were analyzed based on LC-MS combined with the targeted metabolomics method. The anti-inflammatory activity of TFA was evaluated using CuSO4-induced and tail cutting-induced zebrafish inflammation models. Based on the network pharmacology method, the anti-inflammatory mechanism of the main components of TFA was preliminarily predicted. RESULTS: A total of 185 components were identified in TFA. TFA showed significant anti-inflammatory effects on CuSO4-induced and tail cutting-induced zebrafish inflammation models. According to network pharmacology prediction and experimental verification, 10 compounds were identified as the main active ingredients, including 3,7-di-O-methylquercetin, Hesperetin 5-O-glucoside, Myricitrin, et al. Twenty key targets were recognized, such as TNF, AKT1, VEGFA, MMP9, EGFR, PTGS2 et al. Moreover, the TNF signaling pathway and NOD-like receptor signaling pathway were identified to play vital roles in the anti-inflammatory effects of TFA. CONCLUSIONS: This study revealed the chemical profile of TFA and identified the main active ingredients, key targets, and pathways of TFA in anti-inflammatory effects, which is helpful to elucidate the pharmacodynamic substances and action mechanisms of Artemisia vestita Wall. ex Besser, to promote its clinical rational application.

RESUMEN

OBJECTIVE: To investigate the anti-angiogenic activity of Kunxian Capsule (KX) extract and explore the underlying molecular mechanism using zebrafish. METHODS: The KX extract was prepared with 5.0 g in 100 mL of 40% methanol followed by ultrasonication and freeze drying. Freeze dried KX extract of 10.00 mg was used as test stock solution. Triptolide and icariin, the key bioactive compounds of KX were analyzed using ultra-high performance liquid chromatography. The transgenic zebrafish Tg(flk1:GFP) embryos were dechorionated at 20-h post fertilization (hpf) and treated with PTK 787, and 3.5, 7, 14 and 21 µg/mL of KX extract, respectively. After 24-h post exposure (hpe), mortality and malformation (%), intersegmental vessels (ISV) formation, and mRNA expression level of angiogenic pathway genes including phosphoinositide 3-kinase (PI3K), protein kinase B (AKT), extracellular signal-regulated kinases (ERKs), mitogen-activated protein kinase (MAPK), vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF-2) were determined. Further, the embryos at 72 hpf were treated with KX extract to observe the development of sub-intestinal vein (SIV) after 24 hpe. RESULTS: The chromatographic analysis of test stock solution of KX extract showed that triptolide and icariin was found as 0.089 mg/g and 48.74 mg/g, respectively, which met the requirements of the national drug standards. In zebrafish larvae experiment, KX extract significantly inhibited the ISV (P<0.01) and SIV formation (P<0.05). Besides, the mRNA expression analysis showed that KX extract could significantly suppress the expressions of PI3K and AKT, thereby inhibiting the mRNA levels of ERKs and MAPK. Moreover, the downstream signaling cascade affected the expression of VEGF and its receptors (VEGFR and VEGFR-2). FGF-2, a strong angiogenic factor, was also down-regulated by KX treatment in zebrafish larvae. CONCLUSION: KX extract exhibited anti-angiogenic effects in zebrafish embryos by regulating PI3K/AKT-MAPK-VEGF pathway and showed promising potential for RA treatment.
