VEGF and EGFR signaling pathways are involved in the baicalein attenuation of OVA-induced airway inflammation and airway remodeling in mice.

BACKGROUND: Although Traditional Chinese Medicine (TCM) has been used for treating asthma for centuries, the understanding of its mechanism of action is still limited. Thus, the purpose of this study was to explore the possible therapeutic effects, and underlying mechanism of baicalein in the treatment of asthma. METHODS: Freely availabled atabases (e.g. OMIM, TTD, Genecards, BATMAN-TCM, STITCH 5.0, SEA, SwissTargetPrediction) and software (e.g. Ligplot 2.2.5 and PyMoL) were used for disease drug target prediction and molecular docking by network pharmacology. The efficacy and mechanism of action of baicalein in the treatment of asthma were validated using an ovalbumin (OVA)-induced asthma mouse model and molecular biology techniques. RESULTS: A total of 1655 asthma-related genes and 161 baicalein-related targets were identified from public databases. Utilizing common databases and software for network pharmacology and molecular docking analysis, seven potential target proteins for the therapeutic effects of baicalein on asthma were selected, including v-akt murine thymoma viral oncogene homolog 1 (AKT1), vascular endothelial growth factor A (VEGFA), epidermal growth factor receptor (EGFR), proto-oncogene tyrosine-protein kinase Src (SRC), mitogen-activated protein kinase 3 (MAPK3), matrix metallopeptidase 9 (MMP9), and MAPK1. In vivo, baicalein treatment via intraperitoneal injection at a dose of 50 mg/kg significantly reduced airway inflammation, collagen deposition, smooth muscle thickness, lung interleukin (IL)-4 and IL-13 levels, peripheral blood immunoglobulin (Ig)E levels, as well as the count and ratio of eosinophils in bronchoalveolar lavage fluid (BALF) in an OVA-induced asthma mouse model. Further validation by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blotting analysis revealed that the VEGF and EGFR signaling pathways involving VEGFA, MAPK1, MAPK3, and EGFR were inhibited by baicalein in the asthma mouse model. CONCLUSION: Baicalein attenuates airway inflammation and airway remodeling through inhibition of VEGF and EGFR signaling pathways in an OVA-induced asthma mouse model. This will provide a new basis for the development of baicalein as a treatment for asthma and highlights the potential of network pharmacology and molecular docking in drug discovery and development.

Network pharmacology-based prediction of potential effective components of traditional Chinese medicine and their molecular mechanisms of action in the anti-angiogenic treatment of Kaposi′s sarcoma / 中华皮肤科杂志

Objective:To investigate potential effective components of traditional Chinese medicine and their molecular mechanisms of action in the anti-angiogenic treatment of Kaposi′s sarcoma based on network pharmacology, and to predict key targets and signal pathways in the anti-angiogenic treatment of Kaposi′s sarcoma with traditional Chinese medicine.Methods:According to the previous network pharmacology-based analysis results, main chemical components and targets of Rhizoma Polygoni Cuspidati, Cortex Mori, Rhizoma Smilacis Glabrae and Fructus Perillae were obtained by using the traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP); potential therapeutic targets for angiogenesis and Kaposi′s sarcoma were obtained by searching the GeneCard, OMIM, DrugBank and TTD databases, and a Venn diagram was constructed to obtain targets for the interaction between Kaposi′s sarcoma and anti-angiogenic drug components; a protein-protein interaction model was constructed using the STRING 11.5 platform; the Cytoscape 3.6.0 software was used to construct the component-target visual network. Meanwhile, the Metascape platform was used to analyze the Gene Ontology (GO) functions and the enrichment of Kyoto Encyclopedia of Genes and Genome (KEGG) -based pathways. The main active ingredients and core targets obtained through the above analyses were then verified by molecular docking. Results:The core components of anti-Kaposi′s sarcoma angiogenesis drugs were resveratrol (degree: 142), quercetin (degree: 141), kaempferol (degree: 56), luteolin (degree: 56), β-sitosterol (degree: 37), arachidonic acid (degree: 36), naringenin (degree: 36), etc., and the core target was prostaglandin-endoperoxide synthase 2 (PTGS2). KEGG analysis revealed that the cancer signaling pathways were the important pathways related to the inhibiton of angiogenesis in Kaposi′s sarcoma; functional enrichment analysis showed that the positive regulation of cell migration was the most significantly enriched GO term in the biological process category. Molecular docking results showed that resveratrol, quercetin, kaempferol and luteolin had good affinity with PTGS2, especially quercetin and luteolin exhibited the strongest binding abilities to PTGS2, with the binding energies being -9.4 and -9.5 kcal/mol, respectively.Conclusion:This study showed that the 4 traditional Chinese medicines recorded in TCMSP (including Rhizoma Polygoni Cuspidati., Cortex Mori, Rhizoma Smilacis Glabrae and Fructus Perillae) may play an anti-angiogenic role by regulating cancer signaling pathways and acting on targets such as PTGS2, and predicted the possible anti-angiogenesis mechanisms of traditional Chinese medicines in Kaposi′s sarcoma.

Study on the material basis of cold and hot properties of traditional Chinese medicines in Lamiaceae based on pattern recognition / 药学学报

To study the material basis of cold and hot properties of traditional Chinese medicines (TCMs) in Lamiaceae and to establish a cold and hot properties identification model, a database of material components of TCMs in Lamiaceae was established. A three-level classification system of material components was used to obtain the material basis of cold and hot properties of the Lamiaceae family by using data mining methods such as frequency analysis, association rule analysis, logistic regression, and feature selection. Several identification models were established to recognize the cold and hot properties. The chi-square test results showed that the material composition ratios of cold and hot properties were significantly different at the first-level, second-level, and third-level classification (P < 0.05), and the differences varied as the levels of substance classification changed. The average coefficients of variation were 42.30%, 79.07%, and 91.51% at the first-level, second-level, and third-level classification levels, respectively. In other words, in terms of the percentage differences in material composition ratio, the first-level was smaller than the second-level, and the second-level was smaller than the third-level. The results of the association rule analysis showed that under the third-level classification, there were many effective association rules, and 27 core groups and 34 specific groups of chemical components were obtained based on these rules. 15 decisive groups were obtained from the feature selection results. Multinomial logistic regression analysis was used to successfully establish a cold and hot properties identification model with an overall accuracy of 89%. The material basis of cold and hot properties of TCMs in Lamiaceae is different and intersect with each other. Twenty-seven groups of chemical components, such as bicyclic diterpenes, are the core groups of cold and hot properties, of which 15 groups are the decisive groups. The cold and hot properties are often characterized by the interaction of multiple classes of substances, and a single class of substances often cannot be used to characterize the properties. The organic combination of multiple classes of substances is the material basis of cold and hot properties.

ObjectiveTo construct the mental health benefits of physical activity of Tai Chi and framework for college students based on International Classification of Functioning, Disability, and Health (ICF), and to systematically review the effect of physical activity of Tai Chi on anxiety, depression and sleep quality of college students. MethodsRelevant literatures about the health outcomes on anxiety, depression and sleep quality of college students participating in physical activity of Tai Chi were retrieved from databases of Web of Science, PubMed, Medline, Scopus, CNKI, Wanfang data, from the establishment to November 10th, 2022, and screened and reviewed. ResultsTen randomized controlled trials were included finally, from China and U.S.， involving 960 participants (aged 16.4 to 40 years). The main sources were from journals about physical activity and health, with publication dates from 2016 to 2021. The quality of the included literatures was evaluated using the Physical Therapy Evidence Database (PEDro) scale with a mean score of 6.3. The main mental health problems of college students mainly focused on depression, anxiety, high stress, and poor sleep quality. The physical activity of Tai Chi included 24 simplified Tai Chi and Chen style Tai Chi. The frequency of physical activity of Tai Chi was mainly 1 to 6 times a week, 45 to 90 minutes (60 minutes mostly) a time, for 4 to 18 weeks. The health benefits of Tai Chi on anxiety, depression, and sleep quality for college students in the ICF were mainly in the affective function (b152), psychomotor function (b147), energy and drive function (b130), and sleep function (b134). The beneficial outcomes of physical activity of Tai Chi involved reducing anxiety, alleviating depressive symptoms and reducing stress. Compared with physical activity of Tai Chi, physical activity of Tai Chi with the addition of a twenty-four-pattern Taijiquan theory course was more effective in improving depression levels in patients with mild and moderate depression. Tai Chi also can help to improve sleep quality, shorten the time to sleep, and reduce sleep disturbances and daytime dysfunction. ConclusionA PICO framework of Tai Chi for the health benefits of college students has been constructed using ICF. Tai Chi engaged in by college students are mainly 24 simplified Tai Chi. The frequency of physical activity of Tai Chi is 45 to 90 minutes (60 minutes mostly) a time, 1 to 6 times a week, for 4 to 18 weeks. The physical activities of Tai Chi can benefit in reducing anxiety and depression of college students and improving the quality of sleep.

Comparison of Effect of Euodiae Fructus Processed with Different Proportions of Glycyrrhizae Radix et Rhizoma on Oxidative Stress and Autophagy in Mouse Liver Under Toxic Dose / 中国实验方剂学杂志

ObjectiveTo investigate the principle and scientific connotation of Euodiae Fructus（EF） processed with Glycyrrhizae Radix et Rhizoma（Gly） by comparing the effects of unprocessed products of EF（UEF） and processed products of EF with the different proportions of Gly（GEFs） at toxic doses on oxidative stress and autophagy in the liver of mice. MethodSeventy mice were randomly divided into 7 groups， namely the control group， the UEF group， the group of the processed products of EF without Gly（PEF） and 4 groups of GEFs（the mass ratios of EF to Gly were 100∶3， 100∶6， 100∶12 and 100∶24， respectively， hereinafter referred to as the processed products of EF with the mass ratios of 100∶3， 100∶6， 100∶12 and 100∶24 of Gly）. The mice were given purified water， the decoction of UEF， PEF and GEFs by gavage at a dose of 30 g·kg-1. PEF and GEFs were prepared according to the method under EF in the 2020 edition of Chinese Pharmacopoeia. Levels of alanine aminotransferase（ALT） and aspartate aminotransferase（AST） were determined by ultraviolet-visible spectrophotometry， hematoxylin-eosin（HE） staining was used to evaluate the pathological changes of liver tissue， the level of reactive oxygen species（ROS） was detected by fluorescence method， the mRNA expression of heme oxygenase-1（HO-1）， quinone oxidoreductase-1（NQO1）， glutathione-S-transferase 1（GSTA1）， Kelch-like epichlorohydrin-associated protein 1（Keap1） and p62 were measured by Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， western blot was used to detect the protein expression of phosphorylated mammal target of rapamycin（p-mTOR）， phosphorylated ribosomal p70 S6 protein kinase（p-p70S6K）， p62， microtubule-associated protein 1 light chain 3Ⅰ（LC3Ⅰ） and LC3Ⅱ. ResultCompared with the control group， after 7 d of administration， the increase in body mass of mice in the UEF group began to slow down and the difference gradually increased， and the liver body index significantly increased（P<0.01）， pathomorphological observation showed that the structure of hepatic lobules was disordered， and local hepatic sinuses were narrowed or disappeared， and there were inflammatory infiltration and local bleeding， the levels of ALT and AST in serum and ROS in liver tissue were significantly increased（P<0.01）， and the expressions of Keap1， HO-1， NQO1， GSTA1， p62 mRNA and p-mTOR， p-p70S6K， p62 protein in liver tissue were significantly decreased（P<0.01）， and LC3Ⅱ/LC3Ⅰ was significantly increased（P<0.01）. Compared with the UEF group， the body mass of mice increased， and the liver body index， the levels of ALT and AST in serum， and the level of ROS in liver tissue all decreased in the groups of PEF and GEFs. Among these groups， only the liver lobules in GEF（100∶6） group were intact， and the size of liver sinuses was close to that in the control group. The mRNA expressions of Keap1， HO-1， NQO1， GSTA1 and p62 in liver tissue showed an overall upward trend in the groups of PEF and GEFs. Among these groups， only the ones of the above mRNA in the GEF（100∶6） group had a significant increase（P<0.05， P<0.01）. The protein expressions of p-mTOR， p-p70S6K， p62 and LC3Ⅱ/LC3Ⅰ had a callback in the groups of PEF and GEFs， of which the protein expressions of p-mTOR， p-p70S6K and LC3Ⅱ/LC3Ⅰ in the GEF（100∶6） group and the expression of p62 protein in the GEF（100∶24） group had the largest callback. Except for p-mTOR protein， other protein expressions were statistically significant（P<0.05， P<0.01）. ConclusionThe hepatotoxicity of EF is closely related to its ability to induce oxidative stress， which leads to pathological autophagy and hepatocyte damage. This ability can be reduced by the processing with different proportions of Gly， especially the ratio of 100∶6.

Effect of electroacupuncture at Baihui ameliorated neurologic deficit and hemodynamic stability in rat model of post-cardiac arrest syndrome / 中华危重病急救医学

Objective:To observe the results of electroacupuncture (EA) on the resuscitation of a rat model of asphyxia cardiac arrest (CA). And to explore its effect on the neurologic deficits and hemodynamic instability of post-cardiac arrest syndrome (PCAS).Methods:A total of 107 male SD rats were randomly divided into sham, CA, and EA groups. Each group received arterial catheterization and tracheal intubation. The sham group was not induced asphyxia. Asphyxial cardiac arrest was established by endotracheal tube clamping. Rats in the CA group received basic respiratory support and fluid resuscitation in return of spontaneous circulation (ROSC) and rats in the EA group received EA at Baihui based on the treatment of CA group after ROSC, with a dense-dispersed wave at frequencies of 4-20 Hz, while the current intensity was adjusted minimum to induce a twitch of the scalp, the course of treatment was 30 minutes. The baseline data, hemodynamics after ROSC, neurological deficit score (NDS), pathological changes of brain tissue, and levels of serum biomarker were recorded and compared among the three groups. The 72-hour survival of rats was analyzed by Kaplan-Meier survival curve. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of necrotic neurons in the hippocampal CA1 region of rat brain. Meanwhile, Nissl staining and TdT-mediated dUTP nick-end labeling (TUNEL) were used to detect cell apoptosis and injury.Results:Compared with the CA group, the mean arterial pressure (MAP) in the EA group increased significantly at 15 minutes after ROSC [mmHg (1 mmHg≈0.133 kPa): 125.00 (94.00, 136.25) vs. 92.00 (72.00, 122.50), P < 0.05]. There was no significant difference in the NDS score between the EA group and the sham group. Still, the NDS score of the rats in the CA group at 6 hours after ROSC were significantly lower than that in the sham group (46.00±10.61 vs. 80.00±0.00, P < 0.05). Kaplan-Meier survival curve analysis showed that EA did not improve the 72-hour survival rate of rats (100% in the sham group, 25% in the CA group, and 30% in the EA group, P > 0.05). The analysis by TUNEL showed that the apoptosis rate of neurons in CA1 region of the hippocampus in EA group at 6 hours after ROSC was significantly lower than that in CA group [(62.84±2.67)% vs. (71.29±3.70)%, P < 0.05]. Compared with the CA group, the level of serum S100 calcium binding protein B (S100B) in the EA group at 6 hours after ROSC was significantly lower (ng/L: 19.30±13.87 vs. 132.28±31.67, P < 0.05), but there were no significant differences in the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) between these two groups. Conclusions:In the present study, EA at Baihui can stabilize the hemodynamic, moreover, it has a particular neuroprotective effect on PCAS rats. Still, EA at Baihui does not reduce the systemic inflammatory response and improve the survival rate of rats, and its mechanism remains to be verified in further research.

Comparison of gait speed and grip strength for the prediction of all-cause mortality in elderly inpatients / 中华老年医学杂志

Objective:To analyze the relationship between gait speed or grip strength and all-cause mortality in elderly inpatients over 75 years old, and to compare their predictive value for all-cause mortality.Methods:A prospective cohort study was conducted and enrolled elderly patients aged ≥75 years hospitalized from December 2016 to December 2019 at the Department of Integrated Medicine and Geriatrics, Fuxing Hospital, Capital Medical University.Gait speed(m/s)and grip strength(kg)were respectively measured via the 6-meter walk test and a dynamometer.The patients were followed up for more than 1 year after discharge, and the time of all-cause mortality was recorded.The Cox regression model was used to analyze the correlation between gait speed, grip strength or their combination and the risk of all-cause mortality.ROC curves were statistically analyzed using the DeLong test.Results:A total of 704 patients were enrolled, with an average age of(83.8±6.3)years; the median follow-up time was 33(24, 42)months.During the follow-up period, all-cause death occurred in 131 cases(18.6%).Compared with the high gait speed and high grip strength groups, the low gait speed and low grip strength groups had higher all-cause mortality(all P<0.05).The Cox regression model was used to analyze the relationships between gait speed, grip strength and all-cause mortality.The results showed that gait speed( HR=2.255, 95% CI: 1.462-3.477, P<0.001)and grip strength( HR=1.815, 95% CI: 1.232-2.673, P<0.001)were associated with the risk of all-cause mortality after adjustment for other factors; When gait speed slowed down and grip strength decreased, the risk of death reached the highest level( HR=3.156, 95% CI: 1.829-5.445, P<0.001).The AUC of the gait speed model(0.703, 95% CI: 0.667-0.736)was higher than the AUC of the grip strength model(0.648, 95% CI: 0.611-0.683), with a difference of 0.055(95% CI: 0.006-0.103, P=0.026). Conclusions:Decreased gait speed or grip strength is related to an increase of death risk.The risk of death is highest when the patient has both slowed gait speed and decreased grip strength.The predictive value of gait speed for death is better than grip strength.Together they can be used as simple, rapid and effective tools to predict all-cause mortality in this population.

Herbal Textual Research on Ligustici Rhizoma et Radix in Famous Classical Formulas / 中国实验方剂学杂志

By referring to the materials of ancient materia medica， prescriptions and medical books， combining with modern literature， this paper made textual research on the name， origin， producing area， quality evaluation， harvesting and processing methods of Ligustici Rhizoma et Radix in famous classical formulas， so as to provide a basis for the selection and use of Ligustici Rhizoma et Radix in the development of famous classical formulas. Through textual research， it can be seen that Ligustici Rhizoma et Radix is the correct name in all dynasties， but it still has many aliases. The main strain of Ligustici Rhizoma et Radix was Ligusticum sinense and L. jeholense， in addition， there are also L. tenuissimum， Sinodielsia yunnanensis， and Conioselinum vaginatum， L. sinense var. hupehense used in different regions. Since modern times， the textual examination of its scientific name is more complicated. Different foreign scholars have given many scientific names from their local observation， but most of them do not match the actual situation of Ligustici Rhizoma et Radix in ancient China. It is probably because they did not collect the original plants of Chinese Ligustici Rhizoma et Radix and conduct accurate identification. After the founding of the People's Republic of China， the L. sinense and L. jeholense was identified as the original plants through systematic investigation and arrangement of Ligustici Rhizoma et Radix. Since modern times， L. sinense is distributed in the upper and middle reaches of the Yellow River and the south of the region， a small amount of production in Sichuan， Hubei， Hunan and Jiangxi. L. jeholense is distributed in the middle and lower reaches of the Yellow River and the north of the region， mostly produced in Liaoning and Hebei. The ancient harvesting period of Ligustici Rhizoma et Radix was concentrated in January and February according to the lunar calendar with thick roots， dry， fragrant， heavy quality as the best. But now the collection of roots and rhizome more than concentrated in spring before seedling emergence and autumn when leaves were gone， and take the large， dry， yellow， strong， fragrant， less roots， residual short as the best. In the past dynasties， raw products were the main processing methods， and there were also roasting， grinding and so on. Based on the research results， it is suggested that the raw roots and rhizomes of L. sinense and L. jeholense should be used in the development of famous classical formulas.

Effects of Cognitive Behavioral Therapy for Depression and Anxiety, Response Rates and Adverse Events in Patients with Locoregional Advanced Nasopharyngeal Carcinoma.

PURPOSE: This retrospective study investigated the effects of cognitive behavioral therapy (CBT) on depression, anxiety, response rates, and adverse events in patients with locoregional advanced nasopharyngeal carcinoma (NPC). METHODS: A total of 269 patients with diagnosis of stage III-IVA NPC received either CBT plus chemoradiotherapy (CBT group, n = 136) or treatment as usual (TAU) plus chemoradiotherapy (TAU group, n = 133). Patients in the CBT group received a series of 6 CBT sessions for 6 weeks during concurrent chemoradiotherapy. Depression and anxiety were assessed using the Hospital Anxiety and Depression Scale (HADS) score at baseline, the completion of radiotherapy, and 6, 12, and 24 months after radiotherapy. Response rates and adverse events were also evaluated. RESULTS: Patients in the CBT group showed significantly less depression and anxiety than patients in the TAU group after the completion of radiotherapy (P < .05). Complete response rates were 99.3% (135/136) and 92.5% (123/133) in the CBT group and TAU group with a small effect size (Phi coefficient = .171), respectively (P = .005). Compared with the TAU group, the CBT group showed a significantly lower incidence of acute adverse events and late toxic effects. CONCLUSIONS: The addition of CBT to chemoradiotherapy significantly reduced depressive and anxiety symptoms. CBT combined with chemoradiotherapy is associated with improved response rates, with reduced incidence of toxic effects in patients with locoregional advanced NPC. Based on this study, we registered a randomized controlled clinical trials to better define the role of CBT in patients with locoregional advanced NPC (Registration number: ChiCTR2000034701).

Differences in the chemical composition of Dendrobium officinale Kimura et Migo and Dendrobium crepidatum Lindl based on UPLC-Q-TOF-MS/MS and metabolomics / 药学学报

italic>Dendrobium officinale Kimura et Migo is a rare Chinese herbal medicine, while Dendrobium crepidatum Lindl is a local medicine in Yunnan, both of which have the function of nourishing yin and stomach. To reveal the differences in chemical composition between the two species, ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) was used to analyze the chemical composition of stems and leaves of D. officinale and D. crepidatum. Principal component analysis (PCA) and partial least squares discriminant analysis (OPLS-DA) were used to determine the differences in metabolites between species and parts of Dendrobium. Fifty-eight chemical compounds were identified in the two species. Analysis indicated that the side ring of alkaloids connected with nitrogen was readily cleaved during analysis. The results of PCA analysis showed that the stems and leaves of D. officinale and D. crepidatum could be easily differentiated, and the chemical constituents of D. officinale and D. crepidatum were significantly different. OPLS-DA analysis showed that there were 16 metabolite differences between the stems and 22 differences in metabolites between the leaves of D. officinale and D. crepidatum. The main metabolite differences in components between the two Dendrobium species were dendrocrepidine B, dendrocrepidine C and dendrocrepine. There were 14 differences in metabolites between the stems and leaves of D. crepidatum. In conclusion, the chemical compositions of D. officinale and D. crepidatum are quite different; the small molecular compounds of D. officinale are mainly terpenoids and flavonoids, and the content of alkaloids is low. There is no significant difference between stem and leaf. In contrast, D. crepidatum is mainly composed of alkaloids and terpenoids, with crepidamine and dendrocrepine as its unique components, and there are great differences in the components between stems and leaves. This study provides a theoretical basis for the development and utilization of Dendrobium resources.

Study on drug-target binding kinetics profiles of flavonoids in Chrysanthemum morifolium and xanthine oxidase / 中国中药杂志

Based on the target occupancy mathematical model, the binding kinetic process of potential active ingredients of lowering uric acid in Chrysanthemum morifolium with xanthine oxidase(XOD) was evaluated. The potential active ingredients of lowering uric acid in Ch. morifolium were screened by UPLC-Q-Exactivems MS technology, reference substance identification and in vitro enzymatic kinetics experiments. The binding kinetic parameters of xanthine oxidase and potential inhibitor in Ch. morifolium were determined by surface plasma resonance(SPR). The verified mathematical model of the XOD target occupancy evaluated the kinetic binding process of inhibitors and xanthine oxidase in vivo. According to UPLC-Q-Exactive MS and reference substance identification, 39 potential uric acid-lowering active ingredients in Ch. morifolium extracts were identified and the inhibitory activities of 23 compounds were determined. Three potential xanthine oxidase inhibitors were screened, namely genistein, luteolin, and apigenin. whose IC_(50 )were 1.23, 1.47 and 1.59 μmol·L~(-1), respectively. And the binding rate constants(K_(on)) were 1.26×10~6, 5.23×10~5 and 6.36×10~5 mol·L~(-1)·s~(-1), respectively. The dissociation rate constants(K_(off)) were 10.93×10~(-2), 1.59×10~(-2), and 5.3×10~(-2 )s~(-1), respectively. After evaluation by different administration methods, the three selected compounds can perform rapid and sustained inhibition of xanthine oxidase in vivo under combined administration. This study comprehensively evaluated the target occupancy process of three effective components in different ways of administration in vivo by UPLC-MS, concentration-response method, SPR technology and xanthine oxidase target occupancy model, which would provide a new research idea and method for screening active ingredients in traditional Chinese medicine.

Tongxinluo Ameliorates Myocardial Ischemia-Reperfusion Injury Mainly via Activating Parkin-Mediated Mitophagy and Downregulating Ubiquitin-Proteasome System / 中国结合医学杂志

OBJECTIVE@#To investigate the protective effects and mechanism of Chinese herbal compound Tongxinluo Capsule (, TXL) on the Parkin-mediated mitophagy and the ubiquitin-proteasome system in a rat model of myocardial ischemia-reperfusion injury (MIRI).@*METHODS@#Seventy adult male Sprague-Dawley rats were randomly divided into 7 groups: sham group, MIRI group, low- and high-dose TXL (0.5 and 1 g·kg@*RESULTS@#Compared with the sham group, the MIRI group exhibited a larger infarcted area (27.13%±0.01%, P<0.01), a higher apoptotic index (34.33%±2.03% vs.1.81%±0.03%, P<0.01), and higher cTnI expression (14.18±1.01 vs. 7.96±0.32, P<0.01). The mitochondrial integrity was damaged in the MIRI group, while TXL and ATV alleviated the damage of MIRI. More autophagosomes were observed in the high-dose TXL group than in the MIRI group (7.00±0.58 vs. 4.33±1.15, P<0.05). More amounts of PTEN-induced putative kinase protein 1 (PINK1) and Parkin translocated onto the mitochondria were detected in the high-dose TXL group than in the MIRI group (P<0.05). The ubiquitin response was signifificantly downregulated in the high-dose TXL group relative to the MIRI group (P<0.05). CQ administration abolished the activation of autophagy flux and the PINK1/ Parkin pathway induced by high-dose of TXL.@*CONCLUSIONS@#TXL ameliorates MIRI via activating Parkin-mediated mitophagy in rats. The downregulation of the ubiquitin-proteasome system is also involved.
