ObjectiveTo investigate the liver-protecting and anti-liver fibrosis effects of astragaloside Ⅳ （AS-Ⅳ） in vitro and in vivo， as well as its mechanism of action in intervention against liver fibrosis. MethodsIn the animal experiment， C57BL/6J mice were divided into control group， model group， low-dose AS-Ⅳ （20 mg/kg） group， and high-dose AS-Ⅳ （80 mg/kg） group. The mice were given intraperitoneal injection of carbon tetrachloride for 6 weeks to induce liver fibrosis， and since week 3 of injection， the mice in the low-dose AS-Ⅳ group and the high-dose AS-Ⅳ group were given AS-Ⅳ by gavage at a dose of 20 mg/kg and 80 mg/kg， respectively. The serum levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were measured after 4 weeks of administration， as well as the serum levels of hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ N-terminal peptide （PⅢNP）， and collagen type Ⅳ （Col-Ⅳ）. HE staining， picrosirius red staining， and Masson staining were used to observe liver histopathology and collagen deposition； RT-qPCR was used to measure the mRNA expression levels of Acta2， Col1a1， and Col3a1 in liver tissue， and Western blot was used to measure the protein expression levels of α-smooth muscle actin （α-SMA）， collagen type Ⅲ （Col-Ⅲ）， phosphatidylinositol 3-kinase （PI3K）， phosphorylated PI3K （pPI3K）， protein kinase B （Akt）， and phosphorylated AKT （p-Akt） in liver tissue； transcriptome sequencing was performed for liver tissue to identify differentially expressed genes and perform a bioinformatics analysis. In the cell experiment， transforming growth factor-β （TGF-β） was used to induce the activation of LX-2 cells， and the PI3K inhibitor LY294002 and the PI3K activator 740 Y-P were used for intervention. The cells were divided into control group， model group， AS-Ⅳ group， LY294002 group， and AS-Ⅳ+740 Y-P group， and the cells were harvested after 36 hours of intervention. Changes in the protein expression levels of α-SMA， Col-Ⅲ， pPI3K/PI3K， and pAkt/Akt in LX-2 cells were measured， as well as changes in the relative mRNA expression levels of Acta2， Col1a1， and Col3a1. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsIn the animal experiment， compared with the model group， the AS-Ⅳ treatment group had significant reductions in the serum levels of ALT， AST， HA， LN， PⅢNP， and Col-Ⅳ （all P<0.01）， the mRNA expression levels of Acta2， Col1a1， and Col3a1 in liver tissue （all P<0.05）， and the protein expression levels of α-SMA， Col-Ⅲ， pPI3K， and pAkt （Ser473） in liver tissue （all P<0.05）. In the cell experiment， compared with the control group， the model group had significant increases in the protein expression levels of α-SMA， Col-Ⅲ， pPI3K， and pAkt （Ser473） after TGF-β induction （all P<0.05）； compared with the model group， the AS-Ⅳ group had significant reductions in the protein expression levels of α-SMA， Col-Ⅲ， pPI3K， and pAkt （Ser473） （all P<0.05）， and both the AS-Ⅳ group and the LY294002 group had significant reductions in the protein expression level of pPI3K and the relative mRNA expression levels of Acta2， Col1a1， and Col3a1 （all P<0.05）. Compared with the AS-Ⅳ group， there were significant increases in the protein expression level of pPI3K and the relative mRNA expression levels of Acta2， col1a1， and Col3a1 after 740 Y-P intervention （all P<0.05）. ConclusionAS-Ⅳ can inhibit hepatic stellate cell activation and improve liver fibrosis， possibly by inhibiting the PI3K/Akt signaling pathway.

ObjectiveThis paper aims to systematically reveal the effect difference and mechanisms of Zishenwan against chronic prostatitis （CP） before and after salt-processing of Anemarrhenae rhizoma and Phellodendri chinensis cortex based on an integrated strategy of ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry （UPLC-Q-Orbitrap-MS/MS）， network pharmacology， and serum metabolomics. MethodsZishenwan samples before and after salt-processing of Anemarrhenae rhizoma and Phellodendri chinensis cortex were extracted by alcohol-water dual extraction. The chemical components of each sample were detected by UPLC-Q-Orbitrap-MS/MS， and differential components were screened by multivariate statistical analysis. Network pharmacology analysis was performed based on the identified chemical components of Zishenwan to construct a protein-protein interaction （PPI） network of "component， target， and pathway"， and the core components， targets， and pathways of Zishenwan against CP were screened. Forty-two male Sprague-Dawley （SD） rats were randomly divided into a blank group， a model group， a Qianliekang group （1.54 g·kg^-1）， low- and high-dose raw Zishenwan groups （1.8， 5.4 g·kg^-1）， and low- and high-dose salt-processed Zishenwan groups （1.8， 5.4 g·kg^-1）. The CP rat model was established by intraprostatic injection of carrageenan. After one week of recovery， the rats were administered the corresponding drugs for 21 days， while those in the blank group and model group received the same volume of normal saline. After the experiment， serum and tissue samples were collected to evaluate pharmacodynamic indicators including organ indices， histopathology， and inflammatory factors in serum. Subsequently， untargeted serum metabolomics technology was used to analyze metabolite changes and perform pathway enrichment analysis. The network pharmacology was used to construct a network of "differential metabolite， reaction， enzyme， and gene". ResultsA total of 76 components were identified in raw and salt-processed Zishenwan， and 34 differential components were screened by multivariate statistical analysis. Among them， the contents of 14 components， including berberine， berberrubine， and phellodendrine， increased after salt-processing， while the contents of 20 components， such as neomangiferin， decreased. The 28 active components and 185 potential targets were screened out by network pharmacology. The core components included berberine， phellodendrine， magnoflorine， and jatrorrhizine， and the core targets included signal transducer and activator of transcription 3 （STAT3）， protein kinase B1 （Akt1）， and transcription factor AP-1 （JUN）. These targets were significantly enriched in pro-inflammatory signaling pathways such as phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） and mitogen-activated protein kinase （MAPK）. Compared with the model group， all Zishenwan administration groups showed decreased prostate index， reduced levels of interleukin （IL）-1β， IL-18， and B-cell lymphoma-2 （Bcl-2） in serum （P<0.05， P<0.01）， as well as varying degrees of alleviation in histopathological damage. At the same dose， compared with the raw Zishenwan groups， the salt-processed Zishenwan groups showed lower prostate index， pathological scores， and IL-1β， IL-18， and Bcl-2 levels in serum， but the differences were not statistically significant. Metabolomics reveals that 38 differential metabolites were reversed after salt-processed Zishenwan administration. Both raw and salt-processed Zishenwan regulated pathways such as β-alanine metabolism and tryptophan metabolism. In addition to the common regulated pathways， the salt-processed group specifically regulated pantothenate and coenzyme A biosynthesis， pyrimidine metabolism， and arginine and proline metabolism. The intersecting pathways between network pharmacology and metabolomics were tryptophan metabolism and arginine and proline metabolism， with overlapping targets including monoamine oxidase A （MAOA） and arginase 1 （ARG1）. ConclusionThe increased contents of components such as berberine and phellodendrine in salt-processed Zishenwan may enhance its therapeutic effect on CP by inhibiting the PI3K/Akt and MAPK signaling pathways， along with multi-target regulation of tryptophan， arginine， and pantothenate metabolism pathways to comprehensively regulate inflammatory and immune responses.

OBJECTIVE To analyze the serum chemical composition of rats after intragastric administration of water extract of crude Anemarrhenae Rhizoma-crude Phellodendri Chinensis and salted Anemarrhenae Rhizoma-salted Phellodendri Chinensis based on liquid chromatography-mass spectrometry(LC-MS)technology,predict the effect of salt processing on the treatment of type 2 dia-betes in Anemarrhenae Rhizoma-Pheellodendri Chinensis combined with network pharmacology,and preliminarily verify it through in vitro experiments.METHODS Rats were continuously intragastrically administered with crude Anemarrhenae Rhizoma-crude Phello-dendri Chinensis drug pair and salted Anemarrhenae Rhizoma-salted Phellodendri Chinensis drug pair water extract twice,with an in-terval of 1 h.After 60 min of the last administration,the blood was taken from the abdominal aorta,and the protein was precipitated by methanol.After dissolution,the chromatographic column was Shim-pack GIST C18(4.6 mm×150 mm,5 μm);the mobile phase A was 0.1%formic acid water,and the mobile phase B was 0.1%formic acid-acetonitrile;gradient elution,positive and negative ion full scan mode,mass scan range 100-1 500 m/z.Combined with the secondary spectrum of the database and literature,the blood compo-nents of crude Anemarrhenae Rhizoma-crude Phellodendri Chinensis drug pair and salted Anemarrhenae Rhizoma-salted Phellodendri Chinensis drug pair were analyzed and identified.The disease targets of type 2 diabetes were retrieved,and the protein interaction net-work analysis,GO and KEGG pathway enrichment analysis were performed on the intersection targets of blood components and diseases.The"blood components-targets"network diagram was constructed,and the selected core components and core targets were verified by molecular docking using AutoDock software.In the verification experiment,HepG2 cells were used as the experimental ob-ject,and the insulin resistance model was induced by high insulin and high glucose.CCK8 method was used to test the effect of Rhizo-ma Anemarrhenae-Phellodendri Chinensis on cell proliferation before and after salt processing.Western blot was used to detect the ex-pression of PI3K-AKT signaling pathway-related proteins.RESULTS 15 prototype components and 1 mangiferin metabolic compo-nent were identified in the serum of rats.17 prototype components and 1 mangiferin metabolite were identified in the rat serum of the water extract of Anemarrhenae Rhizoma-Phellodendri Chinensis after salt processing.The contents of mangiferin,berberine and 3-isobutylglutaric acid in the blood components after salt-processing were higher than those in the raw products.According to the results of KEGG and GO,the treatment of type 2 diabetes may be related to the transcriptional regulation of RNA polymerase,inflammatory re-sponse,AGE-RAGE,PI3K-AKT pathway and insulin resistance.Cell experiments showed that the ratio of p-PI3K/PI3K,p-AKT/AKT and GLUT4 protein expression could be up-regulated before and after salt processing,and the effect of salt processing group was better than that of the crude group.CONCLUSION This experiment preliminarily revealed the components of Anemarrhenae Rhizo-ma-Phellodendri Chinensis drug pair entering the blood before and after salt exposure,and suggested that ferulic acid,berberine,ber-berrubine,mangiferin,mTOR,SIRT1,EGFR and PPARA may be the main components and targets of Rhizoma Anemarrhenae-Phel-lodendri Chinensis after salt processing to enhance the therapeutic effect of type 2 diabetes.The mechanism may be to enhance the role of PI3K-AKT and other related signaling pathways,providing an important reference for the pharmacodynamic material basis and clini-cal application of Anemarrhenae Rhizoma-Phellodendri Chinensis before and after salt processing.

This article presents a case of acute ST-segment elevation myocardial infarction (STEMI) in a pregnant woman caused by coronary artery dissection. The 41-year-old patient had undergone cardiac valve surgery at the age of 1 and had no risk factors such as hypertension, diabetes, smoking, alcohol use, or a family history of coronary artery disease. At 31 +1 weeks of gestation, she experienced sudden chest pain for 4 hours and was emergently referred to Peking University First Hospital on June 1, 2021. Electrocardiogram revealed ST-segment elevation in leads I, aVL, and V 2 to V 6. Biochemical assays showed elevated levels of high-sensitivity cardiac troponin I and creatine kinase-MB. Echocardiography indicated segmental ventricular wall motion abnormalities (apical) and reduced left ventricular function, confirming the diagnosis of acute anterior wall STEMI. The patient promptly underwent emergency coronary angiography and percutaneous coronary intervention and confirmed coronary artery dissection. Postoperative care included antiplatelet, anticoagulation, and supportive treatment. At 34 +3 weeks of gestation, with the condition of acute anterior wall STEMI being relatively stable, a cesarean section was successfully performed. Regular cardiology follow-ups were scheduled postpartum, and cardiac function was normal in two years after discharge.

Objective To explore the role of MAPK4 in cervical squamous cell carcinoma(CSCC)for the identification of candidate prognostic prediction biomarkers and molecular therapeutic targets.Methods The TCGA cohort was subjected to Kaplan-Meier survival analysis.Immunohistochemistry experiments were conducted on clinical samples to explore the correlation between MAPK4 and patient prognosis.A nomogram was constructed based on MAPK4 mRNA levels.Western blot,CCK-8,colony formation,and Transwell cell function experiments were performed to clarify the abnormal expression and role of MAPK4 in CSCC.DIA proteome sequencing was used to identify effector molecules regulated by MAPK4.Combined with the above cell function experiments,the knockdown of MAPK4 and the overexpression of effector molecules revealed that MAPK4 regulated effector molecules to mediate tumor progression.Results CSCC patients with elevated MAPK4 mRNA levels and high protein expression have a worse prognosis.The constructed nomogram based on MAPK4 can accurately predict the 1-,3-,and 5-year survival rates of patients.Compared with that in normal cervical tissues,MAPK4 protein expre-ssion was up-regulated in tumors.MAP-K4 knockdown substantially inhibited the proliferation,colony formation,mig-ration,and invasion of CSCC ME180 and SiHa cells.SLC3A2 is a downs-tream effector molecule of MAPK4.Overexpression SLC3A2 can weaken the inhibitory effect of MAPK4 knockdown on cell proliferation,colony formation,migration,and invasion.Conclusion MAPK4 is a candidate prognostic biomarker for patients with CSCC.MAPK4 positively regulates SLC3A2 protein expression and accelerates tumor progression,making it a potential molecular therapeutic target for patients with CSCC.

Objective To explore the risk factors of aspiration during hospitalization in patients with ischemic stroke (IS) and establish a predictive model. Methods Based on the case-control design, clinical materials of 316 IS patients treated in the Department of Neurology of Suzhou Ninth Hospital Affiliated to Soochow University from March 2022 to October 2023 were retrospectively collected. According to incidence of aspiration during hospitalization, the patients were divided into case group with 89 cases (aspiration occurred during hospitalization) and control group with 227 cases (no aspiration occurred during hospitalization). Univariate and multivariate Logistic regression analyses were performed in both groups to screen out the risk factors of aspiration during hospitalization in IS patients. R software was used to extract 70 % of the data from the two groups as the training set (establishing a Nomogram model), and the remaining 30 % data was used as test set. Value of predictive model was evaluated by area under the curve (AUC) of the receiver operating characteristic (ROC) curve, calibration curve, and decision curve. Results There were significant differences in the terms of age, the National Institutes of Health Stroke Scale (NIHSS) score, number of lesions, homocysteine (Hcy) level, spontaneous cough, and grading of Wada drinking water test between the case group and the control group (P < 0.05). Multivariate Logistic analysis showed that large age (OR=2.201, 95 %CI, 1.254 to 3.865), high NIHSS score (OR=4.816, 95 %CI, 1.652 to 14.041), multiple lesions (OR=2.649, 95 %CI, 1.249 to 5.613), high level of Hcy (OR=1.501, 95 %CI, 1.044 to 2.158), weakened or absent spontaneous cough (OR=3.384, 95 %CI, 1.639 to 6.987), and high grading of Wada drinking water test (OR=2.878, 95 %CI, 1.422 to 5.783) were the risk factors of aspiration during hospitalization in IS patients (P < 0.05). In the training set, the AUC of the Nomogram model for predicting aspiration during hospitalization in IS patients was 0.872 (95 %CI, 0.827 to 0.919), and was 0.859 (95 %CI, 0.807 to 0.904) in the test set. The calibration curve analysis showed that P value was 0.869 in the training set and 0.898 in the test set. The decision curve analysis for both the training set and test set showed that the Nomogram model was of good clinical applicability. Conclusion The risk of aspiration during hospitalization in IS patients is related to large age, high NIHSS score, multiple lesions, high level of Hcy, weakened or absent spontaneous cough, and high grading of Wada drinking water test. The Nomogram predictive model established on these factors can effectively evaluate the risk of aspiration during hospitalization in IS patients.

A 24-year-old male was admitted due to recurrent redness, swelling, fever and pain in the ankle, frequently accompanied by hungry feeling. Dual energy CT scans showed multiple small gouty stones in the posterior edge of the bilateral calcaneus and in the space between the bilateral metatarsophalangeal joints. The laboratory examination results indicated hyperlipidemia, high lactate lipids, and low fasting blood glucose. Histopathology of liver biopsy showed significant glycogen accumulation. The results of gene sequencing revealed the compound heterozygous mutations of the G6PC gene c.248G>A (p.Arg83His) and c.238T>A (p.Phe80Ile) in the proband. The c.248G>A mutation was from mother and the c.238T>A mutation was from father. The diagnosis of glycogen storage disease type Ⅰa was confirmed.

ObjectiveTo investigate the key compounds affecting the irritation and to clarify the effect of heating and the addition of ginger juice as the auxiliary material during the processing on the irritation of Magnoliae Officinalis Cortex（MOC） by comparing the irritation and composition of volatile oil in MOC and its different processed products. MethodVolatile oil in raw products， water-processed products， ginger-dried products， ginger-fried products（the amounts of ginger were 10%， 50%， respectively） of MOC were extracted by steam distillation and subjected to rabbit eye irritation experiment， and the volatile components of each sample were detected by gas chromatography-mass spectrometry（GC-MS）. Principal component analysis（PCA）and orthogonal partial least squares-discriminant analysis（OPLS-DA） were used to analyze the data of each sample by SIMCA 14.1. The relative contents of different processed products were compared two by two with those of and raw products or ginger-fried products， and the markers that might be related to the irritation were sorted out according to the principles of variable importance in the projection（VIP） value >1 and P<0.05， and the factors influencing the differences in irritation were analyzed. ResultCompared with the blank group， the administration groups all had irritation to the eyes of rabbits， and the degree of irritation was in the order of raw products>water-processed products>ginger-dried products>ginger-fried products（10%）>ginger-fried products（50%）. The results of PCA and OPLS-DA showed that there were differences in the volatile oil from raw products and different processed products. According to VIP value>1 and P<0.05， and combined with the results of eye irritation experiment， ten volatile compounds related to irritation changes were screened out. Among them， cis-cinnamaldehyde was only detected in raw products， the relative contents of β-caryophyllene， （+）-delta-cadinene， α-humulene， γ-muurolene， （-）-isoledene and citral all increased to different degrees， the contents of p-cymene， 1（10）-4-cadinadien-15-ol and β-eudesmol all decreased to different degrees. ConclusionThe irritation of MOC is reduced after heating and processing with ginger juice， and the synergistic effect of both is more effective for reducing irritation. Among the differential markers associated with changes in irritation， the increase in the relative content of citral is closely related to the addition of ginger juice， while the decrease in the relative contents of cis-cinnamaldehyde， p-cymene， 1（10）-4-cadinadien-15-ol is related to heating， and the changes of other components may be related to the synergistic effect of heating and ginger juice.
