ObjectiveTo preliminarily explore the active components and target pathways of Angelicae Sinensis Radix-Polygonati Rhizoma （ASR-PR） herb pair in the treatment of simple obesity through network pharmacology and molecular docking， and to verify and investigate its mechanism of action via animal experiments. MethodsThe chemical constituents and targets of ASR and PR were predicted using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）. Targets related to simple obesity were identified by retrieving the GeneCards， Online Mendelian Inheritance in Man （OMIM）， Pharmacogenomics Knowledgebase （PharmGKB）， and DisGeNET databases. The intersection of drug and disease targets was used to construct an active component-target network using Cytoscape software. This network was imported into the STRING database to construct a protein-protein interaction （PPI） network， and topological analysis was conducted to identify core genes. Gene Ontology （GO） analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis and mapping were performed using the DAVID database and the Microbioinformatics platform. AutoDock 1.5.7 software was used to perform molecular docking between the top five active components and core targets. An animal model of simple obesity was established by feeding C57BL/6J mice a high-fat diet. The mice were administered ASR （2.06 g·kg^-1）， PR （2.06 g·kg^-1）， or ASR-PR （4.11 g·kg^-1） for 10 weeks， while the model group received an equal volume of purified water by gavage. After the administration period， the mice were sacrificed to measure body fat weight and serum levels of total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein （HDL）， and low-density lipoprotein （LDL）. Hematoxylin-eosin （HE） staining was used to observe histopathological sections of liver and adipose tissue. Serum levels of leptin， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） were determined by enzyme-linked immunosorbent assay （ELISA）， and the mRNA expression levels of epidermal growth factor receptor （EGFR） and signal transducer and activator of transcription 3 （STAT3） in liver tissue were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsNetwork pharmacology and molecular docking results indicated that the treatment of simple obesity by ASR-PR may involve the regulation of protein expression of core targets EGFR and STAT3 by its main components MOL009760 （Siberian glycoside A_qt）， MOL003889 （methyl protodioscin_qt）， MOL009766 （resveratrol）， MOL006331 （4′，5-dihydroxyflavone）， and MOL004941 （baicalin）， thereby modulating the PI3K/Akt and JAK/STAT signaling pathways. The animal experiment results showed that compared with the normal group， the model group had significantly increased body weight， body fat weight， and serum levels of TG， TC， TNF-α， IL-6， and leptin （P<0.01）. EGFR mRNA expression was significantly elevated （P<0.05）， while STAT3 mRNA expression was significantly decreased （P<0.01）. Histological analysis revealed disordered hepatic architecture in the model group， with pronounced lipid vacuoles， cytoplasmic loosening， lipid accumulation， and steatosis. Adipocytes in white adipose tissue （WAT） and brown adipose tissue （BAT） of the model group exhibited markedly increased diameters， reduced cell counts per unit area， and irregular morphology. Compared with the model group， the ASR-PR group significantly reduced body weight， body fat weight， serum TC， IL-6， TNF-α， leptin levels， and EGFR mRNA expression （P<0.01）. TG levels were also significantly decreased （P<0.05）， while STAT3 mRNA expression was significantly increased （P<0.01）. Histopathological improvements included reduced size and number of hepatic lipid vacuoles and restoration of liver cell morphology toward that of the normal group. The diameter of adipocytes significantly decreased， and the number of adipocytes per unit area increased. ConclusionASR-PR may regulate the expression of key target proteins such as EGFR and STAT3 via its core active components， modulate the PI3K/Akt and JAK/STAT signaling pathways， repair damaged liver and adipose tissues， and thereby alleviate the progression of obesity in mice.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Objective:To investigate the mechanism of Polygonati Rhizoma-Angelicae Sinensis Radix in the treatment of prediabetes based on network pharmacology and animal experiments.Methods:The active components of Polygonati Rhizoma and Angelicae Sinensis Radix were retrieved from the TCMSP database. The potential targets of the active components were predicted using the Swiss Target Prediction database. The "drug-active component-target" network was constructed by Cytoscape 3.10 software. The disease targets were obtained from OMIM, Genecards, TTD and the U.S. National Library of Medicine. The common targets of drugs and diseases were screened by Venny 2.1.0 platform and imported into STRING database to construct the PPI network. The DAVID database was employed to perform Gene Ontology (GO) functional and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses on the common targets of drugs and diseases. The prediabetes model was established by feeding C57BL/6J mice with high-fat diet. 24 high-fat fed mice were divided into four groups using a random number table: the model group, Polygonati Rhizoma group, Angelicae Sinensis Radix group and Polygonati Rhizoma-Angelicae Sinensis Radix group (herb pair group), with 6 mice in each group. Another 6 normal mice were set as the normal group. Polygonati Rhizoma group was intragastrically administered with Polygonati Rhizoma granule solution at 2.055 g/kg, the Angelicae Sinensis Radix group was intragastrically administered with Angelicae Sinensis Radix granule solution at 2.055 g/kg, and the herb pair group was intragastrically administered with Polygonati Rhizoma-Angelicae Sinensis Radix herb pair at 4.11 g/kg, once daily. The model group and the normal group were intragastrically administered with an equal volume of deionized water for 10 weeks. Fasting blood glucose (FBG) and oral glucose tolerance tests (OGTT) were regularly performed. After 10 weeks of intragastric administration, the levels of serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and fasting insulin (FINS) were measured; glycogen deposition in liver tissues was observed using periodic acid-Schiff (PAS); the mRNA expression levels of FGF1, FGF2, PGF, KDR, IGF1R, INSR, PI3Kca, PI3Kcb, PI3Kcg, Akt1, Akt2 and GSK-3β in liver tissues were detected by Real-time PCR; the protein expression levels of PI3K, phosphorylated (p)-Akt, Akt, p-GSK-3β and GSK-3β in liver tissues of mice were detected by Western blot.Results:205 core targets of Polygonati Rhizoma-Angelicae Sinensis Radix in the treatment of prediabetes were identified; KEGG enrichment analysis revealed that the herb pair may exert hypoglycemic effects by activating the PI3K-Akt signaling pathway. Compared with the model group, the FBG level and AUC values in the herb pair group decreased ( P<0.05), the levels of LDL-C and HDL-C decreased ( P<0.01), the FINS and HOMA-IR levels decreased ( P<0.05), the mRNA expression levels of FGF1, FGF2, PGF, KDR, IGF1R, INSR, PI3Kca, PI3Kcb, PI3Kcg, Akt1, Akt2 and GSK-3β in liver tissues were elevated significantly ( P<0.01), and the protein expression levels of PI3K/β-actin, p-Akt/Akt and p-GSK-3β/GSK-3β in liver tissues of the herb pair group significantly increased ( P<0.01). Conclusion:Polygonati Rhizoma-Angelicae Sinensis Radix may activate PI3K/Akt/GSK-3β signaling pathway by up-regulating FGF1, FGF2, PGF, etc., and affect insulin resistance, glycogen synthesis and other processes, so as to treat prediabetes.

ObjectiveTo evaluate the effects of Wuhua herbal tea on chronic unpredictable mild stress (CUMS)-induced depression and explore its mechanism of action in combating depression.MethodsWe tested the antidepressant effects of Wuhua herbal tea in a rat model of CUMS-induced depression using fluoxetine as a positive control. The rats were divided into four groups: control group, model group, fluoxetine group, and Wuhua herbal tea group. The rats underwent body weight measurements, sucrose preference test, and open-field test. Enzyme-linked immunosorbent assay kits were used to detect the serum levels of serotonin, dopamine, adrenocorticotropic hormone (ACTH), corticosterone, norepinephrine, and interleukin-6. Intergroup comparisons and detection of brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) mRNA expression in the hippocampus were performed using RT-PCR. Immunohistochemistry was used to identify the expression of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) proteins in hippocampal paraffin sections of CUMS rats.ResultsCompared with the control group, the model group rats had depressive tendencies, exhibiting low vitality and interest in various behavioral indicators which were signs of despair. The Wuhua herbal tea group statistically increased the levels of serotonin and dopamine in the serum of CUMS rats to varying degrees (P = .015 and P = .002); reduced serum levels of ACTH, corticosterone, norepinephrine, and interleukin-6 (all P .05); and decreased mRNA expression of BDNF, CREB, JAK2, and STAT3 in the hippocampus (all P .05); and decreased p-STAT3 protein levels (P = .006).ConclusionWuhua herbal tea shows antidepressant potential in CUMS rats by modulating the HPA axis and inhibiting JAK2-STAT3 overactivation, alleviating neuroinflammation. It also restores BDNF-CREB pathway function, reducing depressive symptoms.

Background Some occupational asthma patients have a high risk of poor prognosis, and early assessment and screening of the high-risk groups with poor prognosis are crucial. Objective To evaluate the prognostic value of serum histone deacetylase 2 (HDAC2) and soluble suppression of tumorigenicity 2 (sST2) in occupational asthma patients. Methods An occupational asthma group containing 100 occupational asthma patients admitted to Baodi District People's Hospital of Tianjin between March 2020 and March 2023 were divided into a mild group of 38 cases, a moderate group of 40 cases, and a severe group of 22 cases, and re-divided into a good prognosis group of 66 cases and a poor prognosis group of 34 cases. During the same period, 98 ordinary asthma patients were recruited as the ordinary asthma group and 98 healthy individuals as the healthy control group. A multivariate logistic regression analysis was performed to investigate the relationships of prognosis with HDAC2, sST2, patients separated from allergen after diagnosis, age, body mass index (BMI), gender, smoking history, years of work, family history of asthma, allergy history, good medication adherence, regular follow-up visits. Receiver operating characteristic (ROC) curve was used to evaluate potential predictive value of serum HDAC2 and sST2, and Z-test was used to compare the area under the curve (AUC). Results The serum HDAC2 concentration [(11.13±2.26) ng·L⁻¹] in the occupational asthma group was lower than that in the ordinary asthma group and the healthy control group [(16.72±3.15), (22.75±4.92) ng·L⁻¹], while the sST2 concentration [(16.64±3.47) ng·L⁻¹] in the occupational asthma group was lower than that in the ordinary asthma group and the healthy control group [(12.49±2.31), (9.04±1.98) ng·L⁻¹] (F=256.623, 201.091; P<0.05). The serum HDAC2 concentration [(7.60±1.67) ng·L⁻¹] in the severe group was lower than that in the moderate and the mild groups [(10.02±2.35), (14.34±3.88) ng·L⁻¹], while the sST2 concentration [(24.65±6.31) ng·L⁻¹] in the severe group was lower than that in the moderate and the mild groups [(16.88±3.50), (11.75±3.09) ng·L⁻¹](F=41.731, 67.564; P<0.05). The serum HDAC2 and the proportion of patients separated from allergen after diagnosis in the poor prognosis group were lower than those in the good prognosis group [(8.19±1.94) vs (12.64±3.29) ng·L⁻¹, 64.71% vs 93.94%], and the serum sST2 in the poor prognosis group was higher than that in the good prognosis group [(21.67±5.86) vs (14.05±3.62) ng·L⁻¹] (t/χ²=7.253, 12.177, 8.020; P<0.05). HDAC2 and sST2 were associated with poor 6-month prognosis in the occupational asthma patients (P<0.05). The AUCs for predicting poor prognosis in the occupational asthma patients by serum HDAC2 and sST2 concentrations alone and in combination were 0.826, 0.838, and 0.902, respectively. Conclusion The serum HDAC2 concentration decreases and the sST2 concentration increases in patients with occupational asthma, and these two indicators may have important predictive value for poor disease prognosis.

Objective:To explore the prognostic factors associated with clear cell adenocarcinoma (CCAC) of the uterine cervix based on data in the Surveillance, Epidemiology and End Results (SEER) database.Methods:Clinical data were collected from 431 patients with confirmed CCAC in the SEER database from 1976 to 2017. Survival analysis was performed using the Kaplan-Meier method with log-rank test for comparison between subgroups. Cox proportional hazards model was used to analyze the influencing factors of overall survival (OS).Results:The median age [ M ( Q1, Q3)] of 431 patients was 54 years old (40 years old, 71 years old); there were 333 cases (77.3%) of whit. The median OS time of 431 patients was 93 months (95% CI: 47-148 months), and the 1-, 2-, and 5-year OS rates were 80.1%, 65.8% and 54.2%, respectively. The median OS time was not reached in patients with American Joint Committee on Cancer (AJCC) stage Ⅰ, 83 months (95% CI: 21-144 months) for stage Ⅱ, 32 months (95% CI: 16-47 months) for stage Ⅲ, and 9 months (95% CI: 5-13 months) for stage Ⅳ ( P < 0.001). Median OS time was not reached in patients with SEER stage of localized lesions, 46 months (95% CI: 8-83 months) for regional lesions stage, and 9 months (95% CI: 5-12 months) for distant metastases stage ( P < 0.001). Of the patients with clear AJCC staging and some with unspecified AJCC staging, 118 received surgical treatment alone and 119 received postoperative radiotherapy, the median OS time of the two groups was 443 months (95% CI: 162-723 months) and 102 months (95% CI: 75-129 months), and the difference in OS between the two groups was statistically significant ( P < 0.001). Among the patients with AJCC stage Ⅰ, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 82.5% and 78.5%, the stage Ⅱ were 80.0% and 52.3%, and the stage Ⅲ were 27.8% and 63.3%, respectively; the differences in OS between different stages were not statistically significant (all P>0.05). Among the patients with SEER localized lesions stage, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 88.9% and 73.1%, and the difference was statistically significant ( P = 0.012); the regional lesions stage were 45.5% and 60.0%, and the difference was not statistically significant ( P = 0.568). The results of multivariate Cox regression analysis showed that AJCC staging (stage Ⅰ vs. stage Ⅳ, HR = 0.281, 95% CI: 0.178-0.543, P < 0.001; stage Ⅱ vs. stage Ⅳ, HR = 0.347, 95% CI: 0.113-0.439, P < 0.001; stage Ⅲ vs. stage Ⅳ, HR = 0.399, 95% CI: 0.030-0.145, P < 0.001), SEER staging (localized lesions stage vs. distant metastases stage, HR = 0.104, 95% CI: 0.059-0.182, P < 0.001; regional lesions stage vs. distant metastases stage, HR = 0.301, 95% CI: 0.195-0.463, P < 0.001) and whether or not receive surgery (yes vs. no, HR = 0.359, 95% CI: 0.241-0.535, P < 0.001) were independent influencing factors of OS in CCAC patients. Conclusions:AJCC staging, SEER staging and surgery are independent influence factors for OS in patients with CCAC, and postoperative radiotherapy may not provide more survival benefit.

The aim of this experiment was to investigate the effects of Chinese angelica polysaccha-ride(CAP)on peritoneal macrophage function before and after selenization.In the experiment,CAP and selenized Chinese angelica polysaccharide(sCAP)were applied to mouse peritoneal mac-rophages,and the phagocytic activity of macrophages as well as the expression of the cellular phe-notypes F4/80,MHC-Ⅱ,CD80 and CD86 were detected by flow cytometry,and the changes of IL-6,IL-10,NO,MIP-1α,and TNF-α content in the supernatant of macrophage were detected by ELISA.The results showed that the phagocytic activity of peritoneal macrophages was significantly higher in the sCAP mass concentration of 1.96 mg/L than in the other groups(P＜0.05);and the expression of F4/80,MHC-Ⅱ,CD80 and CD86 were significantly higher in the sCAP mass concen-tration of 1.96 mg/L than in the CAP group and cell control group(P＜0.05);the contents of IL-6,IL-10,NO,and MIP-1α in the supernatant of macrophages were significantly higher than those in other groups when the mass concentration of sCAP ranged from 7.81 to 1.96 mg/L(P＜0.05).The results showed that sCAP had an enhancing effect on the immunomodulatory function of ab-dominal macrophages and was optimal at a mass concentration of 1.96 mg/L.

To investigate the role of chebulagic acid(CA)in regulating lipopolysaccharide(LPS)-in-duced inflammatory response in endometrial tissue of dairy cows,and to provide new ideas for the treatment and new drug development of endometritis in dairy cows.The endometrial tissues of dairy cows were isolated and cultured in vitro,stimulated with 1 mg/L LPS for 1 h and then co-cultured with CA(12.5,25.0,50.0,100.0 mg/L).Then the endometrial tissues of different treat-ment groups were collected for experiments.The protein secretion and gene expression levels of TNF-α,IL-6 and IL-1β were detected by ELISA and real-time fluorescence quantitative PCR.HE staining was used to observe the degree of endometrial tissue damage.The expressions of high mobility protein 1(HMGB-1)and hyaluronidase binding protein 2(HABP-2)were detected by immunofluorescence.The phosphorylation levels of ERK,p65 and IκBα were detected by Western blot.The results showed that the protein secretion levels of TNF-α at 6,24 h and IL-6 at 6,12 and 24 h,and the gene expression levels of IL-1β and IL-6 at 6,9,and 12 h and TNF-α at 6 h were sig-nificantly down-regulated after CA treatment with the LPS-induced endometrial tissue inflammation response model of dairy cows.HE staining showed that compared with the LPS group,the LPS+CA group had some improvements,the degree of epithelial cell exfoliation was reduced,the struc-ture of glands and blood vessels was relatively complete,the degree of inflammatory cell infiltra-tion was reduced,and there was no obvious necrosis or hemorrhage.The expression of HMGB-1 and HABP-2 in LPS+CA group was also significantly down-regulated.The phosphorylation levels of ERK,IκBα and p65 in the LPS+CA group were significantly decreased.In conclusion,CA can reduce LPS-induced inflammation in the endometrial tissue of dairy cows by inhibiting the activa-tion of MAPK and NF-κB pathways and down-regulating the expression of inflammatory factors in the uterine tissue.It is concluded that CA may be a potential therapeutic agent for endometritis in dairy cows and deserves further research and development.
