ObjectiveTo observe the clinical efficacy of Sanren Runchang formula in treating constipation-predominant irritable bowel syndrome (IBS-C) by regulating the brain-gut axis and the effects of the formula on serum levels of 5-hydroxytryptamine (5-HT), vasoactive intestinal peptide (VIP), and substance P (SP). MethodsA randomized controlled design was adopted, and 72 IBS-C patients meeting Rome Ⅳ criteria were randomized into observation and control groups (36 cases).The observation group received Sanren Runchang formula granules twice daily, and the control group received lactulose oral solution daily for 4 weeks. IBS Symptom Severity Scale (IBS-SSS), IBS Quality of Life Scale (IBS-QOL), and Bristol Stool Form Scale (BSFS) were used to assess clinical symptoms, and bowel movement frequency was recorded. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were employed to evaluate psychological status. ELISA was employed to measure the serum levels of 5-HT, VIP, and SP. ResultsThe total response rate in the observation group was 91.67% (33/36), which was higher than that (77.78%, 28/36) in the control group (χ2=4.50, P<0.05). After treatment, both groups showed increased defecation frequency and BSFS scores, decreased IBS-SSS total score, abdominal pain and bloating scores, IBS-QOL health anxiety, anxiety, food avoidance, and behavioral disorders scores, SAS and SDS scores, serum 5-HT and VIP levels, and increased SP levels (P<0.05, P<0.01). Moreover, the observation group showed more significant changes in the indicators above than the control group (P<0.05, P<0.01). The SP level showed no significant difference between the two groups. During the 4-week follow-up, the recurrence rate was 5.88% in the observation group and 31.25% in the control group. No adverse events occurred in observation group, and 2 cases of mild diarrhea occurred in the control group. ConclusionSanren Runchang formula demonstrated definitive efficacy in alleviating gastrointestinal symptoms and improving the psychological status and quality of life in IBS-C patients, with a low recurrence rate. The formula can regulate serum levels of neurotransmitters such as 5-HT and VIP, suggesting its potential regulatory effect on the brain-gut axis through modulating neurotransmitters and neuropeptides. However, its complete mechanism of action requires further investigation through detection of additional brain-gut axis-related biomarkers.

ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction (清肺渗湿汤) combined with western medicine for patients with bronchial asthma of heat wheezing syndrome, and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group, each group with 43 participants. The control group received conventional western medicine, and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group, 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness; secondary outcome measures included traditional Chinese medicine (TCM) syndrome score, asthma control test (ACT) score, pulmonary function indices such as forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), serum inflammatory factor levels including interleukin-4 (IL-4), tumour necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), and immune function indices including CD3+, CD4+, CD8+, CD4+/CD8+. All outcome measures were evaluated before and after treatment. Vital signs were monitored, and electrocardiography, blood routine, urine routine, liver function, and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% (39/40), which was significantly higher than that of the control group (85.0%, 34/40, P<0.05). After treatment, both groups showed decreased TCM syndrome scores, IL-4, TNF-α, hs-CRP, and CD8+ levels, as well as increased ACT scores, CD3+, CD4+, CD4+/CD8+, FEV1, FVC, and PEF levels (P<0.05 or P<0.01). Moreover, the improvements in these indices were more significant in the treatment group than in the control group (P<0.05 or P<0.01). No significant abnormalities in safety indicators were observed in either group, and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms, pulmonary function, and clinical effectiveness, with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

OBJECTIVE To compare the efficacy and safety of evolocumab and probucol in patients with ultra-high-risk atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI). METHODS A retrospective analysis was conducted on 156 ultra-high-risk ASCVD patients who underwent PCI in our institution between January 1, 2023 and December 31, 2024. According to the lipid-lowering regimen, the patients were categorized into evolocumab group ( n =86) and probucol group ( n =70). Changes in lipid parameters [total cholesterol (TC), low-density lipoprot ein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, lipoprotein (a), and lipid goal achievement rate ] , inflammatory markers [interleukin-6 (IL-6) and C-reactive protein (CRP) ] , and cardiac function indices (left ventricular ejection fraction, left ventricular end-systolic diameter, left ventricular end-diastolic diameter, and N-terminal pro-B-type natriuretic peptide) were compared between two groups at baseline and after 6 months of treatment. The incidence of adverse clinical events during treatment, including acute myocardial infarction, in-stent restenosis, acute heart failure, cerebral hemorrhage, and stroke, was also evaluated. RESULTS No statistically significant differences were observed between the two groups at baseline ( P >0.05). After 6 months of treatment, both groups demonstrated significant improvements in lipid profiles (except HDL-C) and inflammatory markers compared to those at baseline ( P <0.05). The evolocumab group exhibited greater reductions in TC, LDL-C, IL-6, and CRP, along with a higher lipid target achievement rate, compared with the probucol group ( P <0.05). There were no statistically significant differences in the cardiac function-related indicators before and after treatment between the two groups, nor in the incidence of adverse events during the treatment ( P >0.05). CONCLUSIONS For ultra-high-risk ASCVD patients after PCI, both of the above treatment options are associated with improvements in blood lipid and inflammatory response, with good safety during short-term follow-up. Evolocumab shows superior efficacy in TC, LDL-C and inflammatory markers reduction and lipid target achievement, compared to probucol.

BackgroundThe violent aggressive behaviors of patients with schizophrenia usually have the characteristics of suddenness, unpredictability, high severity, and great difficulty in prevention. Early identification and accurate assessment of their risk of violent aggression have significant clinical significance. ObjectiveTo construct a predictive model for the violence risk in hospitalized patients with schizophrenia, to identify the key factors influencing the occurrence of violent behavior in these patients, so as to provide references for clinical precise quantitative assessment and early intervention. MethodsA total of 200 patients with schizophrenia who were hospitalized at Taiyuan Psychiatric Hospital from March 2022 to September 2024 and met the diagnostic criteria of the International Classification of Diseases, eleventh edition (ICD-11) were collected to form the modeling cohort. They were randomly divided into a training set (n=140) and a test set (n=60) at a ratio of 7∶3. Based on the least absolute shrinkage and selection operator (LASSO) regression algorithm, the feature variables were screened and dimension-reduced. The support vector machine (SVM) from machine learning was selected for model training and prediction. The discrimination efficacy of the model was evaluated by the area under the receiver operating characteristic (ROC) curve (AUC), accuracy, precision, sensitivity, specificity, F1 value, and Brier value. ResultsLASSO regression screening identified 16 feature variables. Pearson correlation analysis revealed a positive correlation between prior violent behavior frequency and clinical psychiatric symptom scores (r=0.580, P<0.01), a positive correlation between hospitalization compliance and current disease status (r=0.550, P=0.003), and a positive correlation between educational level and family per capita monthly income (r=0.367, P<0.01). The SVM model achieved an AUC of 0.853, accuracy of 0.800, precision of 0.810, sensitivity of 0.895, specificity of 0.636, F1 value of 0.850, and Brier value of 0.168. ConclusionThe SVM model has a relatively high level of applicability and overall predictive performance in the assessment of violent risk in schizophrenia patients, which is helpful for the early identification of violent risks in such patients.

ObjectiveTo investigate the mechanism of salt processing of Psoraleae Fructus (PF) through modern analytical techniques and biotechnology, focusing on its effects related to hepatotoxicity and anti-osteoporosis activity. MethodsThe zebrafish model was utilized to evaluate the impact of PF and salt-processed Psoraleae Fructus (SPF) on the hepatotoxicity (using 134.17 , 178.89, 268.34 mg·L-1 as low, medium, and high dose groups of PF, 135.04, 180.06, 270.08 mg·L-1 as low, medium, and high dose groups of SPF, respectively) and anti-osteoporotic activity (using 33.54 , 67.08 and 134.17 mg·L-1 as low, medium, and high dose groups of PF, 33.76, 67.52, 135.04 mg·L-1 as low, medium, and high dose groups of SPF, respectively), which was using alizarin red skull staining of zebrafish as an indicator of different batches of PF. The specific dosage of a batch of PF was taken as an example. Then ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry(UPLC-Q-TOF-MS) analysis was employed to identify the chemical composition of PF before and after salt processing, and PCA, OPLS-DA, and independent sample t-test were used to elucidating the compositional changes associated with the effects of salt processing on hepatotoxicity and anti-osteoporosis activity. ResultsUnder specific conditions, PF induced notable hepatotoxicity in zebrafish while simultaneously demonstrating protective effect against prednisolone-induced osteoporosis. In comparison to PF, SPF showed alleviated hepatotoxicity while retaining significant anti-osteoporosis activity. UPLC-Q-TOF-MS analysis revealed that after salt processing, the overall chemical composition of PF showed a downward trend, with 69 components showing a decrease in content, represented by psoralen, and 13 components showing an increase, represented by 4′-O-methyl psoralen B. Further multivariate statistical analysis revealed 11 key differential components before and after salt processing of PF, including psoralen and bakuchiol. ConclusionSalt processing effectively diminishes hepatotoxicity without impairing therapeutic efficacy against osteoporosis of PF, which may be related to the compositional changes before and after salt processing of PF and provides key evidence to reveal the scientific significance of salt processing of PF.

Objective To comprehensively analyze the current epidemic characteristics and disease burden of brucellosis in Tongliao City, and to provide a basis for the prevention and control strategy of brucellosis in Tongliao City. Methods The report data of brucellosis in Tongliao City from 2018 to 2023 were collected. Descriptive methods were used for data analysis, and the disability-adjusted life years and indirect economic losses were calculated. Results From 2018 to 2023, a total of 22 034 cases were reported in Tongliao City, with an average annual incidence of 136.17/100 000. The incidence was statistically different between men and women ( χ2=12.23, P=0.032). The majority of cases were farmers (94.25%), followed by herdsmen (1.67%). The age group was concentrated between 30-60 years old (79.30%), among which the majority of cases were in the 40-50 years group (6 883/22 034). The onset time had seasonal characteristics, and the peak period was from March to August (the seasonal index was between 115.40%-151.29%). In terms of regional distribution, cases were reported in all counties (banners). The average annual incidence was highest in Kulun Banner (233.85/100 000) and Zalut Banner (210.13/100 000), and lowest in Keerqin District (42.28/100 000) and Holingol City (31.87/100 000). The analysis of disease burden showed that a total of 677.55 person-years (YLD) were lost from 2018 to 2023, with an average annual loss of 112.92 person-years. The total indirect economic loss was 59.3576 million yuan, with an average annual loss of 9.892 9 million yuan, and the people over 60 years old had the lowest annual loss. Conclusion The overall brucellosis epidemic in Tongliao City has shown a fluctuating downward trend. The epidemic prevention and control should be strengthened in farmers, people aged 40-50 years old, and areas such as Zalut Banner and Kulun Banner to further control the epidemic of brucellosis.

ObjectiveTo investigate the potential mechanisms of Zingiberis Rhizoma in treating inflammatory bowel disease (IBD) by integrating network pharmacology with in vitro and in vivo experiments. MethodsTraditional Chinese Medicine Systems Pharmacology Database And Analysis Platform (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID) Database were used to obtain the active component targets of Zingiberis Rhizoma. GeneCards was used to obtain the IBD targets. DAVID was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses on core targets. Cytoscape 3.10.2 was used to establish the "active component-disease target-signaling pathway" interaction network. Mice were randomly assigned to control, model, and Zingiberis Rhizoma (400 mg·kg-1) groups. An IBD model was induced via dextran sulfate sodium (DSS). The colonic tissue was collected post-treatment to assess histology, expression of Ly6C+ monocytes/macrophages, and mRNA levels of Toll-like receptor 4 (TLR4), and inflammatory cytokines. The effect of Zingiberis Rhizoma aqueous extract on RAW264.7 cell viability was evaluated. Furthermore, the effects of the extract at 100, 10, and 1 mg·L-1 on LPS-induced differentiation of RAW264.7 cells into Ly6Chi monocytes/macrophages, mRNA levels of TLR4 and inflammatory cytokines, and protein levels of factors in the TLR4/mitogen-activated protein kinase (MAPK) signaling pathway. ResultsA total of 241 targets were identified for Zingiberis Rhizoma and 6 787 for IBD, with 122 shared targets among Zingiberis Rhizoma, ulcerative colitis (UC), and Crohn's disease (CD). The enrichment analyses yielded 297 GO terms and 88 KEGG pathways. Associations were noted between Zingiberis Rhizoma's active component targets and IBD targets. In vivo experiments: Compared with the control group, the model group showed decreased body weight and disease activity index (DAI)(P<0.01), shortened colon length, damaged mucosal epithelium with inflammatory cell infiltration, raised pathological scores (P<0.05), increased Ly6Chi and Ly6Clo monocytes/macrophages (P<0.05), and up-regulated mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.05) and protein levels of TLR4, phosphorylated extracellular signal-regulated protein kinase 1/2 (p-ERK1/2), and phosphorylated p38 MAPK (p-p38 MAPK) (P<0.05). Zingiberis Rhizoma intervention reversed these changes and reduced Ly6Chi monocytes/macrophages (P<0.01). In vitro experiments: compared with the control, LPS increased the proportion and number of Ly6Chi monocytes/macrophages and mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.01) and enhanced the expression of TLR4, p-ERK1/2, and p-p38 MAPK (P<0.05). Zingiberis Rhizoma reduced Ly6Chi monocytes/macrophages (P<0.05), down-regulated the mRNA levels of inflammatory cytokines (P<0.05), and suppressed the TLR4/MAPK pathway (P<0.05). ConclusionZingiberis Rhizoma alleviates IBD by suppressing the TLR4/ERK/p38 MAPK signaling pathway and reducing inflammatory cytokine levels in Ly6Chi monocytes/macrophages.

ObjectiveTo clarify the repair effect of Mume Fructus on the intestinal mucosal epithelial barrier in the mouse model of inflammatory bowel disease (IBD) and explore the repair mechanism. MethodsThirty-six male C57BL/6 mice were randomly assigned into six groups: normal, model, low-, medium-, and high-dose (200, 400, and 800 mg·kg-1) Mume Fructus, and sulfasalazine (300 mg·kg-1). Except the normal group, the rest groups had free access to 2% dextran sulfate sodium (DSS) solution for seven days to establish the IBD model, followed by a seven-day drug intervention. The body weight change and disease activity index (DAI) were recorded. After the last administration, spleen and colon tissue samples were collected to analyze the differences in colon length and spleen index. Hematoxylin-eosin staining was used to observe the morphology of the colon tissue. The level of diamine oxidase (DAO) in the serum was measured by the DAO assay kit. Immunohistochemistry was employed to determine the expression of tight junction proteins such as Claudin-1, Occludin, and zonula occludens-1 (ZO-1) in the colon tissue. Real-time PCR was performed to measure the mRNA levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the colon tissue. Finally, Western blot was employed to determine the protein levels of mitogen-activated protein kinase kinase (MEK), extracellular signal-regulated kinase (ERK), phosphorylated (p)-MEK, and phosphorylated ERK in the colon tissue. ResultsCompared with the normal group, the model group exhibited decreases in body weight and colon length (P<0.01), increases in DAI, spleen index, and serum DAO level (P<0.01), damaged colonic epithelium and goblet cells, and obvious infiltration of inflammatory cells. In addition, the model group exhibited higher positive expression of Claudin-1, Occludin, and ZO-1 (P<0.01), higher mRNA levels of TNF-α and IL-1β (P<0.01), and higher protein levels of p-MEK and p-ERK (P<0.05, P<0.01) than the normal group. However, sulfasalazine and three doses of Mume Fructus markedly decreased the body weight and DAI (P<0.05), recovered the colon length and spleen index, alleviated colon tissue damage, lowered the level of DAO in the serum (P<0.01), and down-regulated the mRNA levels of TNF-α and IL-1β (P<0.01) and the protein levels of p-MEK and p-ERK (P<0.05). Sulfasalazine and low- and medium-dose Mume Fructus increased the positive expression of Occludin, Claudin-1, and ZO-1 (P<0.05, P<0.01). Furthermore, high-dose Mume Fructus elevated the protein expression of Occludin (P<0.05). ConclusionMume Fructus can restore the expression of intestinal epithelial tight junction proteins by inhibiting the phosphorylation of proteins in the MEK/ERK signaling pathway and down-regulating the levels of TNF-α and IL-1β, thus repairing the intestinal mucosal barrier in the mouse model of IBD.

ObjectiveTo investigate the modulating effect of modified Wumeiwan (MWMW) on the ulcerative colitis (UC)-associated intestinal helper T cell 17 (Th17)/regulatory T cell (Treg) balance and intestinal flora by using a human flora-associated model of UC patients with dampness-heat obstruction syndrome, thus providing a new idea for the UC-related research and therapeutic strategies. MethodsThe 24 male C57BL/6J mice were randomized into normal control, model, and MWMW groups (n=8). Model and MWMW groups were first treated with an antibiotic cocktail (vancomycin, 0.1 g·kg-1; neomycin sulfate, 0.2 g·kg-1; ampicillin, 0.2 g·kg-1; metronidazole, 0.2 g·kg-1) for 21 days. At the end of antibiotic treatment, the gavage of fecal microbiota suspension from UC patients with dampness-heat obstruction syndrome was started at a dose of 0.2 mL·d-1 for 19 consecutive days, by which a human flora-associated model of UC was obtained. The MWMW group was administrated daily with MWMW liquid (12.5 g·kg-1), while the normal control and model groups were administrated by gavage with an equal amount of sterile water for 7 consecutive days. The symptoms of dampness-heat obstruction were observed. The colon length and spleen index were measured and calculated, and the proportions of Th17 and Treg cells were detected by flow assay. The intestinal flora was analyzed by 16S rRNA high-throughput sequencing. ResultsCompared with the normal control group, the model group showed shortened colon (P<0.05) and increased spleen index (P<0.01). Compared with the model group, the MWMW group showed prolonged colon (P<0.01) and decreased spleen index (P<0.05). After the intervention of MWMW, the Th17 proportion and Th17/Treg ratio in the colon decreased (P<0.01), and the proportion of Treg cells increased (P<0.05). The number of species and alpha and beta diversity of intestinal flora in mice were regulated by MWMW (P<0.05). In terms of intestinal flora composition, MWMW increased the relative abundance of several phyla (Firmicutes, Proteobacteria, Fusobacteriota, Actinobacteriota, and Gemmatimonadota), the genus Bacteroides, and two species (Bacteroides thetaiotaomicron and B. fragilis) in model mice. Moreover, Spearman's correlation analysis showed that the relative abundance of B. thetaiotaomicron and B. fragilis were negatively correlated with the Th17 level (P<0.05). In addition, the above changes in intestinal flora caused the changes in microbial genes involved in 14 pathways, such as glycolysis, amino acid degradation, inorganic nutrient metabolism, biosynthesis of pyrimidine deoxyribonucleotides, antibiotic resistance, and degradation of polysaccharides. ConclusionsThe human flora-associated model successfully simulated the changes (marked by a decrease in the abundance of Bacteroides) of intestinal flora in UC patients with dampness-heat obstruction syndrome. MWMW can enrich the abundance of beneficial bacteria such as B. thetaiotaomicron and B. fragilis and promote the synergistic intestinal immune modulation with the metabolic functions centered on glycolysis, amino acid metabolism, and nucleotide synthesis through bacterial polysaccharide utilization sites to reduce the Th17/Treg ratio, thereby exerting a protective effect on UC.

OBJECTIVE To explore the effects and potential mechanism of Huangqi jianzhong decoction on intestinal inflammation in the rats of irritable bowel syndrome with diarrhea (IBS-D) based on the mitogen-activated protein kinase (MAPK)/ nuclear factor-κB (NF-κB) signaling pathway. METHODS Male SD rats were selected. Ten rats were randomly chosen as the control group, and the remaining rats (50 rats) were used to prepare the IBS-D model by acetic acid enema+restraint stress. The rats with successful modeling were randomly divided into the IBS-D group, the traditional Chinese medicine (TCM) group (Huangqi jianzhong decoction 15 g/kg), the positive control drug group (Rifaximin tablets 150 mg/kg), the activator group (anisomycin 125 μg/kg, the activator of p38 MAPK), and the TCM+activator group (Huangqi jianzhong decoction 15 g/kg+ anisomycin 125 μg/kg), with 10 rats in each group. Rats in each group were given a gavage or tail vein injection of the corresponding medicine liquid or the same volume of normal saline, once a day for two consecutive weeks. After the last administration, feces within 24 hours were collected for the calculation of fecal water content and fecal trait score, and the minimum volume threshold was detected. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 in serum were detected; the pathological changes of colonic tissue were observed; the expressions of tight junction protein ZO-1, occludin mRNAs and proteins related to the MAPK/NF- κB signaling pathway in colonic tissue were determined. RESULTS Compared with the control group, obvious edema and inflammatory cell infiltration could be observed in the colonic tissue of rats in the IBS-D group. The fecal water content and trait score, serum levels of inflammatory factors, as well as the protein phosphorylation levels of p38 MAPK and NF-κB p65 in the colonic tissue were significantly increased, while the minimum volume threshold and the mRNA expressions of ZO-1 and occludin were significantly decreased or down-regulated (P<0.05). Compared with the IBS-D group, the pathological changes of colonic tissue in the TCM group and positive control drug group were alleviated, and the above indicators improved significantly (P<0.05), while the above indicators in the activator group deteriorated further (P<0.05). Compared with the TCM group, the above indicators in the TCM+activator group were significantly reversed (P<0.05). CONCLUSIONS Huangqi jianzhong decoction can alleviate colonic inflammation in IBS-D rats, relieve visceral hypersensitivity, and has a certain protective effect on their intestinal barrier function. The above-mentioned effects may be related to the inhibition of the MAPK/NF- κB signaling pathway.
