ObjectiveTo characterize the changes of metabolites of Blumea balsamifera in the process of sweating by non-targeted metabolomics， and to investigate the influence of sweating processing on the constituents of B. balsamifera. MethodsUltra performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap-MS） metabolomics was used to identify the metabolites in no sweating group（F1）， sweating 2 d group（F2） and sweating 4 d group（F3）， the differences of metabolites between the groups were compared by principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， and differential metabolites were screened according to the variable importance in the projection（VIP） value>1 and P<0.05， and the pathway enrichment of the differential metabolites was analyzed by Kyoto Encyclopedia of Genes and Genomes（KEGG）. ResultsThe results of PCA and OPLS-DA showed a clear distinction between the three groups of samples， indicating significant differences in the compositions of the three groups of samples. A total of 433 differential metabolites were screened between the F1 and F2， with 154 up-regulated and 279 down-regulated， the significant up-regulated metabolites were tangeritin， 5-O-demethylnobiletin and so on， while the metabolites with significant down-regulation included alternariol， fortunellin， etc. A total of 379 differential metabolites were screened between the F2 and F3， with 150 up-regulated and 229 down-regulated， the significant up-regulated metabolites were isoimperatorin， helianyl octanoate and so on， and the significant down-regulated metabolites were hovenoside I， goyasaponin Ⅲ， etc. KEGG pathway enrichment analysis showed that tyrosine metabolism， isoquinoline alkaloid biosynthesis， phenylalanine， tyrosine and tryptophan biosynthesis， tryptophan metabolism， valine， leucine and isoleucine biosynthesis， pantothenate and coenzyme A biosynthesis may be the key pathways affecting metabolite differences of B. balsamifera after sweating treatment. ConclusionSweating can reduce the content of endophytic mycotoxins in B. balsamifera and has a great impact on the synthesis and metabolic pathways of total flavonoids and auxin. This study can provide a reference for the process research on the sweating conditions of B. balsamifera.

This study applied the grading of recommendations assessment, development and evaluation(GRADE) system and the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(Eff-iEC) to evaluate the evidence for 12 commonly used Chinese patent medicines for the treatment of osteoporosis, which are frequently recommended in guidelines or expert consensuses. The results showed that Xianling Gubao Capsules/Tablets were rated as C(low-level evidence) according to the GRADE system, and as BA~+B~+(intermediate evidence) according to the Eff-iEC system. Jintiange Capsules were rated as C(low-level evidence) by the GRADE system, and as AA~+B(high-level evidence) by the Eff-iEC system. Gushukang Granules/Capsules were rated as C(low-level evidence) by GRADE system, and as BA~+B~+(intermediate evidence) by Eff-iEC system. Zuogui Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Qianggu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B~+(high-level evidence) by Eff-iEC system. Zhuanggu Zhitong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BA~+B(intermediate evidence) by Eff-iEC system. Jingui Shenqi Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B(high-level evidence) by Eff-iEC system. Quanduzhong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AD~+B~+(low-level evidence) by Eff-iEC system. Epimedium Total Flavones Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AAB~+(high-level evidence) by Eff-iEC system. Yougui Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~(++)B~(+ )(high-level evidence) by Eff-iEC system. Qigu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BB~+B(intermediate evidence) by Eff-iEC system. Liuwei Dihuang Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Overall, the Eff-iEC system provides a more comprehensive assessment of the effectiveness evidence for traditional Chinese medicine(TCM) than the GRADE system. However, it still has certain limitations that hinder its wider promotion and application. In terms of clinical evidence evaluation, both the Eff-iEC and GRADE systems reflect that the current clinical research quality on Chinese patent medicines for the treatment of osteoporosis is generally low. High-quality clinical trials are still needed in the future to further validate clinical efficacy.

Hepatocellular carcinoma (HCC) expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming. Aldolase A (ALDOA) plays a prominent role in glycolysis; however, little is known about its role in HCC development. In the present study, we aim to explore how ALDOA is involved in HCC proliferation. HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout, which is consistent with ALDOA overexpression encouraging HCC proliferation. Mechanistically, ALDOA knockout partially limits the glycolytic flux in HCC cells. Meanwhile, ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase; ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function. A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun, and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells. In HCC patients, the expression level of ALDOA was correlated with the phosphorylation level of c-Jun (Thr93) and poor prognosis. Remarkably, hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models, and the knockdown of A ldoa strikingly decreased HCC development in vivo. Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription, opening additional avenues for anti-cancer therapies.

OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Aim To explore the molecular mechanism of luteolin against acute lung injury by network phar-macology and molecular docking technology,and to conduct experimental verification.Methods The re-lated targets of luteolin were predicted by PubChem and Swiss Target Prediction databases.Acute lung in-jury-related targets were collected through the Gene-Cards database.Venny 2.1 was used to draw the Venn diagram,and the common targets of drug and disease were obtained.The protein interaction network(PPI)was established by String online platform,and the core targets were screened by Cytoscape 3.8.2 software.The functional enrichment analysis of Gene Ontology(GO)and pathway enrichment analysis of Kyoto Ency-clopedia of Gene and Genome(KEGG)were per-formed on the common targets using the DAVID data-base,and the results were visualized.Finally,molecu-lar docking was performed by Auto Dock software,and the molecular results were visualized by Pymol.The mouse acute lung injury model was constructed.HE staining was used to detect histopathology,and Western blot was used to detect lung tissue related proteins.Results After screening,85 common targets were ob-tained.Among them,the core targets were AKT1,EG-FR,SRC,MMP9,ESR1,PTGS2,etc.GO enrichment analysis obtained 265 biological processes,including signal transduction,protein phosphorylation,and nega-tive regulation of apoptosis.There were 48 cells,main-ly including plasma membrane,cell solute,cytoplasm,etc.There are 107 molecular functions,mainly inclu-ding ATP binding,protein serine/threonine/tyrosine ki-nase activity,protein kinase activity and so on.A total of 92 signaling pathway were obtained by KEGG path-way enrichment analysis,which mainly acted on PI3 K-AKT signaling pathway,ErbB signaling pathway,VEGF signaling pathway,etc.Molecular docking results showed that luteolin had good docking activity with core targets AKT1,EGFR,SRC,MMP9,ESR1,PTGS2,MMP2,GSK3 B,KDR and PARP1.The binding ener-gy of ERS1,GSK3B and MMP2 was lower than-5.0 kal·mol-1,and the affinity with luteolin was stronger.The pathological results of lung tissue showed that lute-olin could inhibit inflammatory infiltration and had a strong anti-inflammatory effect in LPS-induced acute lung injury model in mice.Western blot experiments showed that luteolin might alleviate the inflammatory response by inhibiting the phosphorylation of AKT.Conclusions Luteolin can play an anti-acute lung in-jury role through multi-target and multi-channel mecha-nisms,which may be closely related to the inhibition of AKT phosphorylation.

The study aims to investigate and compare the effects of probiotics and docosahexaenoic acid (DHA) with the Alzheimer's disease (AD) therapeutic drug donepezil on the learning cognition and brain damage related indexes in AD mice, and to provide experimental basis for its treatment of AD. All animal experiments were approved by the Ethics Committee of the Henan University of Chinese Medicine (ethics number DWLL2018080003). Fifty male C57BL/6J mice were randomly assigned to one of five groups: sham-operated, model, donepezil (10 mg·kg^-1), probiotic (2.7×10⁹ CFU·d^-1), and DHA (0.104 g·kg^-1). Except for the sham-operated group, the AD animal model was established by injecting Aβ_25-35 (200 μmol·L^-1) in the lateral ventricle, followed by gavage administration for 4 weeks. In all mouse groups, learning memory ability, neuronal morphology in the hippocampus, apoptosis of primary hippocampal cells, and immune cell levels were detected. The levels of Aβ_1-42, Aβ_1-40, p-Tau, AchE, Ach, oxidative stress, glial cell activation, and the inflammatory factors IL-1β, IL-10, and TNF-α in the brain tissue of mice were also detected. 16S rDNA sequencing was used to further investigate the effects of donepezil and probiotics on AD. Donepezil, probiotics and DHA improved cognitive deficits and enhanced learning memory in Aβ_25-35-induced mice by increasing locomotion time, locomotion distance, autonomic alternation rate, and shortening the time to reach the plateau; it significantly attenuated Aβ_25-35-induced brain injury and neuroinflammation in mice by decreasing Aβ_1-42, Aβ_1-40, p-Tau, AchE, IL-1β, TNF-α, and MDA and increasing the levels of Ach, IL-10, GSH-Px, and T-SOD in brain tissues, as well as decreasing the activation of glial cells, and had a modulatory effect on immune cells. 16S rDNA sequencing shows that both donepezil and probiotics restore flora homeostasis and that differential bacteria are strongly associated with cognition, AD pathology, and neuroinflammation. Combining all indicators, donepezil and probiotics were more effective than DHA. All in all, donepezil, probiotics and DHA ameliorate Aβ_25-35-induced cognitive dysfunction and brain damage in mice by modulating immune cells, reducing the number of apoptotic cells and glial cell activation in the brain, and decreasing the levels of oxidative stress and inflammatory factor expression, among which the effects of donepezil and probiotics were better than those of DHA, and the therapeutic effects of donepezil and probiotics on AD were closely related to the modulation of gut microbiome.

Parabacteroides distasonis is a gram-negative bacterium initially isolated from a clinical specimen in the 1930s. The strain was re-classified to form the new genus Parabacteroides in 2006. P. distasonis can regulate intestinal barrier function and plays a key role in immune response and metabolic regulation of bodies. Traditional Chinese medicine(TCM) is closely related to the intestinal microbiota. Polysaccharides, saponins, and other ingredients of TCM can treat diseases by interacting with P. distasonis, but the specific mechanisms underlying these processes are still unclear, requiring further exploration. This study reviewed the roles and related mechanisms of P. distasonis in inflammatory-immune diseases, metabolic diseases, cardiovascular disease, neuropsychiatric diseases, cancer, and other diseases and summarized the relevant research results of TCM to prevent and treat diseases by regulating P. distasonis. This study provides a reference for subsequent exploration of P. distasonis and research on the interaction between TCM and intestinal microbiota.

Plasma metabolomics based on UHPLC-Q-TOF-MS/MS technique was developed for profiling the mechanism on attenuating hepatic fibrosis of Bupleuri Radix (BR) and Paeoniae Radix Alba (PRA) before and after vinegar-processing and compatibility, and to screen potential pharmacodynamic substances by spectrum-effect correlation method in this study. Firstly, SD rats with CCl₄-induced hepatic fibrosis were used as an in vivo model. The blood and tissue samples were collected for the analyses of pharmacodynamic indexes and plasma metabolomics after six weeks’ administration of BR, vinegar-processed BR (VPBR), PRA, vinegar-processed PRA (VPPRA), BR-PRA herb-pair, and VPBR-VPPRA herb-pair. The experiment was approved by the experimental animal ethics committee from Nanjing University of Chinese Medicine (No.202103A002). The results of pharmacodynamics indicated that the levels of alanine aminotransferase (ALT, P < 0.01), aspartate aminotransferase (AST, P < 0.01), and hydroxyproline (HYP, P < 0.01) were decreased significantly, while the level of glutathione peroxidase (GSH-Px, P < 0.05) was increased obviously after administration of all treatment groups. Next, UHPLC-Q-TOF-MS/MS was performed to characterize the endogenous metabolites. A total of 20 differential endogenous metabolites related to the pathogenesis of hepatic fibrosis were identified in positive and negative ion modes, mainly involving five metabolic pathways of retinol metabolism, glycerol phospholipid metabolism, glyceride metabolism, fatty acid biosynthesis, and arachidonic acid metabolism. Meanwhile, a concept named correction rate was introduced to evaluate the back-regulation effects of all treatment groups on differential metabolites, and 10 differential metabolites were corrected by all treatment groups. The correction effects of the vinegar-processed herb groups were better than those of the crude ones, and the correction effects of the herb-pair groups were better than those of the single ones. Interestingly, the best correction effect was found in the VPBR-VPPRA herb-pair group, which further verified the efficacy improvement through vinegar-processing and compatibility. Partial least square method and VIP analysis combined with spectrum-effect correlation were applied for screening pharmacodynamic markers, and 38 ingredients with higher correlation with four classical pharmacodynamic indexes (ALT, AST, HYP, and GSH-Px) were identified as pharmacodynamic markers of the anti-hepatic fibrosis effects of BR and PRA before and after vinegar-processing and compatibility. The results of the investigation could not only lay a foundation for clarifying the pharmacodynamic materials and mechanism of vinegar-processing and compatibility of BR and PRA in the treatment of hepatic fibrosis as well as provide a theoretical basis for demonstrating the scientific connotation of processing and compatibility, but also provide a reference for further drug design and development of BR and PRA in clinic.

A quantitative analysis method for six principal active constituents (acubin, geniposidic acid, chlorogenic acid, pinoresinol di-O-glucopyranoside, geniposide, and pinoresinol 4-O-glucopyranoside) of crude Eucommiae Cortex (EC) and its salt-processed product extracts was developed to investigate and compare their pharmacokinetic behaviors in adenine-induced renal fibrotic rats in vivo. UHPLC-QqQ-MS/MS technology was employed. Scan was conducted in negative ion mode and quantitative determination was carried out by MRM paired ion. The established method was fully validated by specificity, linearity, precision, accuracy, stability, recovery, and matrix effect, and the results of methodological investigation met the requirements of biological sample analysis. Then, a quick, sensitive, and accurate method was successfully established, which could simultaneously measure the contents of six active constituents of crude and salt-processed EC extracts in rat plasma. After a single administration to renal fibrotic rats of crude EC and its salt-processed product extracts, the plasma concentration of each constituent at different time points was measured, the pharmacokinetic parameters were calculated and the concentration time curves were structured. The experiment was approved by the experimental animal ethics committee from Nanjing University of Chinese Medicine (No. 202103A008). The results showed that compared to the crude Eucommiae Cortex group, the t_max of aucubin, pinoresinol di-O-glucopyranoside, geniposide, and pinoresinol 4-O-glucopyranoside in the salt-processed Eucommiae Cortex group rat plasma were significantly lower than those in the crude group (P < 0.05, P < 0.01); the C_max and AUC_{0-48 h} of chlorogenic acid, the C_max, AUC_{0-48 h} and AUC_0-∞ of pinoresinol di-O-glucopyranoside, and the C_max of geniposide and pinoresinol 4-O-glucopyranoside were significantly higher than those in the crude group (P < 0.05, P < 0.01). Our investigation found that compared to crude Eucommiae Cortex, a variety of active ingredients could play a role of quick effect with higher peak blood concentration and bioavailability after oral administration of salt-processed Eucommiae Cortex, which were consistent with the traditional Chinese medicine theory of "salt-processing enhancing drug into kidney meridian", providing an experimental basis for the selection of quality control indexes and the in-depth study of processing mechanisms and metabolic rules in vivo of Eucommiae Cortex and its salt-processed product.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.
