ObjectiveThis study aims to elucidate the potential mechanism of Zuojinwan in improving liver fibrosis through hepatic tissue metabolomics analysis. MethodsTwenty-four mice were randomly allocated into normal group， model group ， positive drug group （silymarin， 100 mg·kg^-1）， and Zuojinwan group （Zuojinwan solution， 2.5 g·kg^-1）， with per group six mice. Liver fibrosis model was induced via intraperitoneal injection of olive oil solution with 10% carbon tetrachloride （CCl₄） （0.5 μL·g^-1， three times weekly for 8 weeks） in all groups except the normal group. During the final 4 weeks， the silymarin group received silymarin （100 mg·kg^-1） by gavage thrice weekly， while the Zuojinwan group was administered Zuojinwan solution （2.5 g·kg^-1） under the same regimen. After the last administration， the levels of liver fibrosis indicators and liver injury markers in serum were detected. The pathological morphological changes of the liver tissues were observed. The levels of liver fibrosis markers α-smooth muscle actin （α-SMA） and Collagen Ⅰ（ColⅠ） were detected. Metabolomics was analyzed on mice's liver tissues. The mice's serum was collected for metabolomics analysis. ResultsCompared with the model group， Zuojinwan significantly improved indicators related to liver fibrosis and liver injury. Compared with the normal group， the model group showed significantly elevated levels of fibrosis markers such as laminin （LN）， hyaluronic acid （HA）， procollagen typeⅢ （PC-Ⅲ）， and type Ⅳ Collagen （Ⅳ-C）， while liver injury indicators such as alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， alkaline phosphatase （ALP）， lactate dehydrogenase （LDH）， and total bilirubin （TBIL）， exhibited a marked upward trend （P<0.05）. Compared with the model group， the silymarin group showed a significant decrease in the aforementioned indicators （P<0.05）. Notably， compared with the model group， the Zuojinwan group exhibited a significant reduction in all these indicators （P<0.05）， with efficacy comparable to that of the silymarin group. Zuojinwan reduced mRNA and protein levels of α-SMA and ColⅠ in the liver tissue. Metabolomics results revealed that compared with the model group， Zuojiinwan significantly reduced levels of glucose metabolism-related metabolites such as D-fructose 1，6-bisphosphate （FBP）， nicotinamide adenine dinucleotide phosphate （NADPH）， sodium beta-D-fructose 6-phosphate （F6P）， dihydroxyacetone phosphate （DHAP）， fumaric acid， and D-glucose 6-phosphate （G6P） （P<0.05）. Serum enzyme-linked immunosorbent assay （ELISA） was used to detect glucose metabolism indicators and further validate the regulatory effect of Zuojinwan on glucose metabolism. ConclusionThese results suggest that Zuojinwan may improve liver fibrosis by regulating the dysregulated levels of glucose metabolism during the progression of liver fibrosis.

Over the past two decades, genome-wide association study(GWAS) has identified numerous genetic variants and loci associated with heritable diseases. With the gradual maturation and saturation of GWAS methodologies, transcriptome-wide association study(TWAS) offers a novel perspective by linkinggenetic phenotypes to gene expression levels. By integrating TWAS with other multi-omics analyses, researchers can gain a deeper understanding of heritable diseases. This article provides an overview of recent groundbreaking and representative TWAS methods and tools, analyzes their strengths and limitations, and discusses future trends in TWAS development.

The differences in microscopic characteristics between the Plantago asiatica from different populations were mainly reflected in the number of non-glandular hairs on the leaf surface, the shape of the petiole endothelial layer cells, and the number of large vascular bundles, and the number of layers of mesophyll palisade tissue cells, etc. Conclusion Plantago asiatica from different populations can be identified through mini-character and microscopic; by comparing the relevant identification features, which can provide a basis for revising and improving the standards of Plantago asiatica.

OBJECTIVE To investigate the equivalence of different decoction processes based on rat model of hypertension with liver-yang hyperactivity. METHODS Inductively coupled plasma mass spectrometry （ICP-MS） was used to compare the dissolution differences of inorganic elements in the powder-directly-decocted decoction versus the pieces-decocted-first decoction of Ostreae Concha- Haliotidis Concha- Margaritifera Concha drug pair. Six SD rats were included in the normal group. The spontaneously hypertensive rats were given Aconite decoction for six weeks to induce the hypertension model with liver-yang hyperactivity. After successful modeling， 48 rats were randomly divided into the model group， the captopril group [positive control， 8 mL/（kg·d） ] ， as well as low-， medium-， and high-dose groups of pieces decocted first or directly powder decocted [2.02， 4.05， 8.10 mL/（kg·d） ] ， with 6 rats in each group. Each group received the corresponding drug or equal volume of pure water intragastrically， once a day， for two consecutive weeks. After the last administration， the degree of irritability， facial temperature， pressure pain threshold， blood pressure， and pathological changes of the thoracic aorta were observed in each group. Serum nitric oxide （NO） and plasma angiotensin Ⅱ （Ang Ⅱ）， renin， and aldosterone （ALD） levels were also measured. RESULTS ICP-MS analysis results showed statistically significant differences in the contents of macroelements Li， Na， Mg， Ca， Mn， Ga， Sr， Mo， Cd， Sn， and Sb， between the powder-directly-decocted decoction and the pieces-decocted-first decoction （ P ＜0.05） ，the elements P， Cr， Fe， Ni， Zn， Hg， Tl， and Pb were not detected in either decoction. Animal experiments showed that after two weeks of administration， compared with the model group， the facial temperature， and blood pressure decreased in all treatment groups， while the pressure pain threshold increased； plasma levels of Ang Ⅱ， renin and ALD， as well as the serum level of NO were all decreased， and thoracic aortic media thickness was significantly reduced， most of the differences in the above indicators were statistically significant （ P ＜0.05 or P ＜0.01 or P ＜0.001）. Pathological observation showed improvement in thoracic aortic pathological injury. CONCLUSIONS The powder-directly-decocted process for the Ostreae Concha- Haliotidis Concha- Margaritifera Concha drug pair significantly promotes the dissolution of key elements such as Ca， Mg， and Sr without increasing the dissolution of harmful elements. It is equivalent to the traditional pieces-decocted-first in alleviating liver-yang hyperactivity syndrome， lowering blood pressure， and protecting the vascular endothelium， and even shows better performance in some indicators.

ObjectiveTo compare the effects of different formulations of Yinqiao Powder （银翘散， YP） on inflammation and immune function in a rat model of acute pharyngitis induced by ammonia water. MethodsA rat model of acute pharyngitis was established by spraying 15% ammonia water into the pharynx of male SD rats using a laryngeal atomizer twice daily （three sprays each time） for three consecutive days. Successfully modeled rats were randomly divided into 5 groups， including a model group （normal saline， 10 ml/kg）， YP decoction group （10.73 g/kg）， YP granule group （10.73 g/kg）， cydiodine group （0.39 mg/kg） and blank control group （normal saline， 10 ml/kg）， with 12 rats in each group. All groups received intragastric administration once daily for 10 consecutive days. After the final gavage administration， frequency of back arching per minute， frequency of vibrissae grooming per minute， and grooming episodes per five minutes were recorded in rats. The cumulative body weight change was calculated as the difference in body weight between day 10 and day 1 of gavage administration. Behavioral observations were performed using the open field test， and the total distance traveled was recorded. After sample collection， the lung index and thymus index were calculated. Histopathological changes in the pharyngeal and tracheal tissues were observed using HE staining. Serum inflammatory markers including eosinophil cationic protein （ECP）， angiotensin-converting enzyme 2 （ACE2）， and C-reactive protein （CRP）， as well as immune parameters including immunoglobulin M （IgM）， immunoglobulin A （IgA）， immunoglobulin G （IgG）， CD4， CD4/CD8 ratio， and CD8 were measured by ELISA. In addition， ELISA was used to determine the levels of inflammatory mediators in pharyngeal tissues， including phospholipase A2 （PLA2）， cyclooxygenase-1 （COX-1）， cyclooxygenase-2 （COX-2）， prostaglandin E2 （PGE2）， vascular cell adhesion molecule-1 （VCAM-1）， C-X-C motif chemokine ligand 1 （CXCL1）， vascular endothelial growth factor （VEGF）， and matrix metalloproteinase-9 （MMP-9）. ResultsCompared to the blank control group， the model group exhibited significantly increased frequencies of back arching per minute， vibrissae grooming per minute， and grooming episodes per five minutes， and lung index， and decreased cumulative body weight change， thymus index， and total distance traveled， as well as elevated serum levels of ECP， ACE2， and CD8， reduced levels of IgM， IgA， IgG， CD4， and CD4/CD8 ratio， and increased levels of PLA， COX-1， COX-2， PGE2， VCAM-1， CXCL1， VEGF， and MMP-9 in pharyngeal tissues （P＜0.05）. Histopathological examination revealed keratinization of the superficial epithelial layer of the pharyngeal mucosa， accompanied by congestion and edema in the lamina propria and infiltration of inflammatory cells； in the tracheal mucosa， extensive inflammatory cell infiltration， ciliary disruption， and goblet cell damage were observed. Compared to the model group， except for CRP， IgG， and CD4， all above mentioned indicators were improved in the YP granule group， YP decoction group， and cydiodine group （P＜0.05）. Histopathological lesions in the pharyngeal and tracheal tissues were also alleviated. Compared to the YP decoction group， rats in the YP granule group exhibited decreased frequencies of back arching per minute， vibrissae grooming per minute， and grooming episodes per five minutes， as well as reduced serum ECP levels. Meanwhile， the cumulative body weight gain and serum levels of IgM， IgA， IgG， and CD4/CD8 increased， whereas CD8 levels decreased （P＜0.05）. ConclusionYP can effectively alleviate symptoms of acute pharyngitis in a rat model， improve inflammatory responses and immune-related indicators， demonstrating superior therapeutic effects in the dosage form of granule.

ObjectiveTo investigate whether the effect of Danggui Shaoyaosan （DSS） on cognitive impairment is related to its promotion of ketone body metabolism in the brain and regulation of glutamate/α-amino-3-hydroxy-5-methyl-4-isox-azolepropionic acid receptor （AMPAR） pathway. MethodsMale APP/PS1 mice were randomized into model， low-dose （3.2 g·kg^-1） DSS， medium-dose （6.4 g·kg^-1） DSS， high-dose （12.8 g·kg^-1） DSS， ketogenic diet， and inhibitor （talampanel， 5 mg·kg^-1） groups. C57BL/6J wild-type mice were selected as the normal group. The talampanel group was intragastrically administered for 2 consecutive weeks from the 6th week， and the other groups were continuously treated for 8 weeks before behavioral testing. The ultrastructure of synapses in hippocampal CA1 region was observed by transmission electron microscopy， and calcium/calmodulin-dependent kinase Ⅱ （CaMKⅡ） expression was detected by immunohistochemistry （IHC）. The levels of β-hydroxybutyrate （BHB） and lactic acid （LAC） were measured by biochemical kits， and those of glutamate （Glu）， glutamine （Gln）， γ-aminobutyric acid （GABA）， and synaptophysin （SYP） by enzyme-linked immunosorbent assay （ELISA）. The mRNA levels of glutamine synthetase （GS）， glutaminase （GLS）， glutamate decarboxylase （GAD）， CaMKⅡ， and AMPAR subunits GluA1 and GluA2 were quantified by Real-time quantitative polymerase chain reaction （Real-time PCR）， and the protein levels of GS， GLS， GAD， GluA1， and GluA2 by Western blot. ResultsCompared with the normal group， the model group exhibited decreased recognition index， spontaneous alternation rate， and residence time in the target quadrant （P<0.01）， increased escape latency and ratio of the time in the opposite side of the target quadrant to the time in the target quadrant （P<0.05， P<0.01）， damaged synaptic ultrastructure of hippocampal CA1 region， increased positive expression of CaMKⅡ， no significant difference in BHB level， elevated LAC and Glu levels （P<0.01）， declined SYP， Gln， and GABA levels （P<0.01）， downregulated mRNA and protein levels of GS， GAD， and GluA2 （P<0.05， P<0.01）， and upregulated mRNA and protein levels of GLS and GluA1 （P<0.05， P<0.01） and mRNA level of CaMKⅡ （P<0.01）. Compared with the model group， DSS intervention improved the behavioral indexes of mice （P<0.05， P<0.01）， enhanced the synaptic ultrastructure plasticity in hippocampal CA1 region， decreased the positive expression of CaMKⅡ， raised the BHB level （P<0.01）， reduced the LAC and Glu levels （P<0.01）， elevated the SYP， Gln， and GABA levels （P<0.01）， upregulated the mRNA and protein levels of GS， GAD， and GluA2， and downregulated the mRNA and protein levels of GLS and GluA1 （P<0.05， P<0.01） and the mRNA level of CaMKⅡ （P<0.01）. ConclusionDSS can improve the learning and memory and enhance the synaptic plasticity of APP/PS1 mice. Its neuroprotective effect is coupled with the promotion of ketone body formation and remodeling of brain energy metabolism， and is related to the regulation of glutamate/AMPAR pathway.

Diabetes mellitus （DM） is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells， posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs， including the eyes， heart， liver， kidneys， nerves， and feet， making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications， challenges such as high costs and adverse drug reactions remain. Thus， identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component， astragaloside Ⅳ， possesses various biological activities， including anti-inflammatory， antioxidant， and antiviral effects， as well as benefits for cardiac and cerebral function， nerve conduction， and myocardial protection. Meanwhile， the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a crucial role in regulating oxidative stress， inflammatory responses， apoptosis， and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications， leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally， it highlights its protective effects on basic cardiac function， inhibition of retinal cell damage， improvement of cerebral nerve dysfunction， reduction of chronic kidney and liver damage， and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer， astragaloside Ⅳ， in the treatment of DM and its complications.
