ObjectiveTo optimize the extraction method for polysaccharides from turnip(Brassica rapa), and analyze and evaluate the primary structure of the isolated and purified turnip polysaccharide fraction(BP-1) and its hypoglycemic effects in diabetic zebrafish. MethodsTaking polysaccharide yield as the evaluation index, a semi-bionic extraction method was employed. Single-factor experiments and Box-Behnken response surface methodology were used to investigate three factors of solid-to-liquid ratio, extraction time and extraction temperature, in order to optimize the extraction process. BP-1 was isolated and purified using the Sevage method and DEAE-52 cellulose column chromatography. Structural characterization of the turnip polysaccharides was performed using ultraviolet-visible spectrophotometry(UV), gas chromatography-mass spectrometry(GC-MS), Congo red assay, and Fourier-transform infrared spectroscopy(FT-IR) to determine purity, monosaccharide composition, triple-helix structure, and functional groups. The microstructure of the polysaccharides was observed using scanning electron microscopy(SEM) and atomic force microscopy(AFM). Zebrafish were divided into the blank group(adding E3 medium), and BP-1-1, BP-1-10, BP-1-50, BP-1-200, BP-1-1 000 groups(adding BP-1 solutions at concentrations of 1, 10, 50, 200, 1 000 mg·L-1, respectively), and zebrafish embryos were subjected to a 96-hour exposure experiment. The maximum tolerated concentration of BP-1 in zebrafish was determined by evaluating its effects on phenotype, survival rate, malformation rate, and heart rate. Experimental animals were randomly divided into the blank group, model group, BP-1-10 group(10 mg·L-1), BP-1-50 group(50 mg·L-1), and BP-1-200 group(200 mg·L-1). The blank group was cultured in E3 medium, the model and treatment groups were induced to establish a diabetic model in 4 day-post-fertilization(dpf) zebrafish embryos using 10 g·L-1 of glucose combined with 500 µmol·L-1 of alloxan. The treatment groups received corresponding doses of BP-1 solution, while the blank and model groups received an equal volume of saline. Glucose and insulin(INS) levels were measured using enzyme-linked immunosorbent assay(ELISA) kits, the effects on the liver were observed by hematoxylin-eosin(HE) histopathological sections. The mRNA expression levels of glucagon(Glucagon), insulin(Insa), and phosphoenolpyruvate carboxykinase 1(PCK1) were detected with real-time fluorescence quantitative polymerase chain reaction(Real-time PCR). ResultsThe optimized extraction conditions were determined as follows:solid-to-liquid ratio of 1∶40(g·mL-1), extraction time of 66 min, and extraction temperature of 79 ℃. Under these conditions, the yield of turnip polysaccharides was (10.34±0.96)%. UV analysis indicated that BP-1 contained no proteins or nucleic acids, GC-MS analysis revealed that BP-1 consisted of six monosaccharides(arabinose, rhamnose, ribose, mannose, galactose and glucose). Congo red assay indicated that the molecular conformation did not exhibit a triple-helix structure, FT-IR analysis showed the presence of α-glycosidic bonds and uronic acids, SEM analysis revealed an irregular flaky structure with a flat and smooth surface, AFM analysis suggested that the aggregated structure might be formed by the entanglement of molecular chains and intramolecular hydrogen bonding. The maximum tolerated concentration of BP-1 in zebrafish over 96 h was determined to be 200 mg·L-1. Pharmacodynamic results showed that, compared with the blank group, the model group exhibited significantly increased glucose levels and significantly decreased INS levels(P<0.01). Compared with the model group, the BP-1-50 group significantly reduced glucose levels and increased INS levels(P<0.05). Histopathological examination of liver tissue revealed that various doses of BP-1 had a certain reparative effect on damaged liver tissue. The liver tissue structure in the BP-1-200 group was nearly normal, with hepatocytes appearing plump. Real-time PCR results showed that, compared with the blank group, the model group exhibited significantly upregulated mRNA expressions of Glucagon and PCK1, and significantly downregulated mRNA expression of Insa(P<0.01). Compared with the model group, the BP-1-50 and BP-1-200 groups showed significantly downregulated mRNA expressions of Glucagon and PCK1, and significantly upregulated mRNA expression of Insa(P<0.01). ConclusionThe semi-bionic extraction method for turnip polysaccharides yields a high extraction rate, is simple to operate, has low costs, making it suitable for large-scale industrial production. BP-1 consists of six monosaccharides, contains α-glycosidic bonds and uronic acids, exhibits hypoglycemic activity, and provides a certain protective effect on the liver of alloxan-induced diabetic model zebrafish.

ObjectiveTo investigate the material basis and mechanism of action of Tuoli Xiaodu San in treating ulcerative colitis (UC) by integrating transcriptomics, network pharmacology, and experimental validation. MethodsNetwork pharmacology was initially employed to screen the active components and potential mechanisms of Tuoli Xiaodu San for treating UC. A UC mouse model was established by dextran sulfate sodium (DSS) induction. The mice were divided into the following groups: normal, model, high-dose (11.3 g·kg-1) Tuoli Xiaodu San, low-dose (5.7 g·kg-1) Tuoli Xiaodu San, and positive control (mesalazine, 0.4 g·kg-1). Intragastric administration commenced on day 1 of modeling and continued for 7 consecutive days. The disease activity index (DAI) was assessed daily. Hematoxylin-eosin (HE) staining was used to observe colonic pathological changes. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Transcriptome sequencing was performed on mouse colonic tissues, and the results were integrated with network pharmacology findings for in-depth analysis of Tuoli Xiaodu San's potential mechanisms in treating UC. Finally, the expression of key genes and proteins in the identified signaling pathways were detected using Western blot and Real-time polymerase chain reaction (Real-time PCR). ResultsThe combined analysis of network pharmacology and transcriptomics results showed that the multi-pathway network with phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway as its core was the key mechanism of Tuoli Xiaodu San in the treatment of UC. Tuoli Xiaodu San administration significantly ameliorated weight loss, diarrhea, and bloody stools in UC mice, reduced the DAI scores (P<0.05, P<0.01), lowered the colonic histopathological scores (P<0.01), alleviated colon shortening (P<0.01), and downregulated serum levels of TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01). Molecular biology experiments confirmed that Tuoli Xiaodu San significantly inhibited the mRNA and protein expression, as well as the phosphorylation levels, of PI3K, Akt, and p65 in colonic tissues (P<0.05, P<0.01). ConclusionTuoli Xiaodu San can regulate the multi-pathway network with PI3K/Akt as its core through multi-component synergy, thereby reducing colonic inflammatory damage and exerting a therapeutic effect on UC.

ObjectiveTo investigate the impact of portal vein tumor thrombus (PVTT) classification on rebleeding in hepatocellular carcinoma (HCC) patients with different PVTT subtypes and esophagogastric variceal bleeding (EGVB), and to provide a reference for formulating rational treatment regimens for such patients. MethodsA retrospective study was performed for 130 patients with HCC and PVTT who were treated due to EGVB in Beijing Ditan Hospital, Capital Medical University, from July 2020 to January 2025, and according to whether endoscopic treatment was performed, the patients were divided into endoscopic treatment group with 97 patients and conservative treatment group with 33 patients. Demographic and clinical data were collected from all patients, and the two groups were compared in terms of hemostasis success rate and rebleeding rate. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to estimate the cumulative incidence rate of rebleeding in patients with different subtypes of PVTT. Propensity score matching (PSM) was performed for the endoscopic treatment group and the conservative treatment group to balance the baseline data of the two groups. The Cox proportional hazards model was used to perform univariate and multivariate analyses and identify independent risk factors for rebleeding. ResultsThe endoscopic treatment group had a significantly lower cumulative rebleeding rate within 6 months than the conservative treatment group (35.1% vs 57.6%, hazard ratio [HR]=0.480, 95% confidence interval [CI]: 0.272—0.851, P=0.019). The PVTT Ⅲ—Ⅳ group had a significantly higher cumulative rebleeding rate within 6 months than the PVTT Ⅱ group (52.2% vs 37.5%, HR=1.744, 95%CI: 1.008 — 3.018, P=0.022). After PSM, there was no significant difference in rebleeding rate between the endoscopic treatment group and the conservative treatment group (38.1% vs 14.3%,HR=1.500,95%CI:0.125 — 2.002, P=0.588), while the PVTT Ⅲ—Ⅳ group had a significantly higher cumulative rebleeding rate than the PVTT Ⅱ group (58.8% vs 12.5%,HR=1.561,95%CI:1.195 — 12.499,P=0.033). The multivariate Cox regression analysis showed that PVTT subtype (HR=1.412, 95%CI: 0.998 — 1.997, P=0.049), platelet count (HR=1.006, 95%CI: 1.001 — 1.010, P=0.021), C-reactive protein (HR=1.011, 95%CI: 1.001 — 1.021, P=0.026), and ascites (HR=1.803, 95%CI: 1.059 — 3.068, P=0.030) were independent risk factors for rebleeding. ConclusionFor HCC patients with PVTT and EGVB, endoscopic treatment can successfully achieve hemostasis, while it fails to significantly reduce rebleeding rates. PVTT classification can affect the risk of rebleeding, and patients with PVTT types Ⅲ—Ⅳ have a relatively high rebleeding rate.

Objective To investigate and compare the effects of electroacupuncture and dexamethasone on lung function and histomorphology and behavior in the offspring of perinatal nicotine exposure(PNE)rats.Methods Twenty-four pregnant Sprague-Dawley rats were randomly divided into control,model,electroacupuncture shallow needling,and dexamethasone groups using the random number table method(n=6 rats per group).A pulmonary dysplasia model in offspring rats with PNE was prepared by cervicodorsal subcutaneous injection with nicotine,and successful establishment of the model was confirmed by demonstrating statistically significant differences in growth parameters,lung function,and lung morphology compared to the control group.From the sixth day of maternal conception,the control group received cervicodorsal subcutaneous injection with 0.9%sodium chloride solution(1 mg/kg once per day),and the remaining groups were similarly injected with nicotine(1 mg/kg once per day).Concurrent with the nicotine injections,the electroacupuncture shallow needling group received electroacupuncture interventions at the"Zusanli"(ST 36)acupoint on both sides once a day for 20 min.In contrast,the offspring rats in the dexamethasone group received intraperitoneal dexamethasone injections from postnatal day 8(1.5 mg/kg once per day for 3 days),with a later dose of 0.75 mg/kg once per day for 4 days.Following successful model establishment,four offspring per rat were retained in each group using the random number table method.Until the 21st day after the birth of the offspring,using the random number table method,one offspring randomly selected from the four retained offspring per rat in each group was assigned to growth parameter assessment including body weight,lung weight,and lung index;simultaneously,one offspring was randomly selected for pulmonary function which was detected by a small animal pulmonary function machine,with the parameters of forced vital capacity(FVC),functional residual capacity(FRC),dynamic lung compliance(Cdyn),peak expiratory flow(PEF),peak inspiratory flow(PIF),and airway resistance(RL);concurrently,one offspring was randomly selected for hematoxylin and eosin staining to observe the histomorphology of the lung tissue,alveolar numbers,and mean alveolar septal thickness;additionally,one offspring was randomly selected for Morris water maze testing to evaluate the effects of the two intervention methods on learning and memory capabilities in offspring rats with PNE.Results Compared with the control group,the body weight,lung weight,lung index,FVC,PEF,FRC,Cdyn,alveolar number,platform crossing times,target quadrant time percentage,and target quadrant path percentage in the Morris water maze experiment were significantly decreased in the offspring rats of the model group(P<0.01).In contrast,PIF,RL,average thickness of alveolar septa,and latency of the Morris water maze experiment were significantly increased in the offspring rats of the model group(P<0.01).Compared with the model group,both electroacupuncture shallow needling group and dexamethasone group exhibited significant increases in body weight,lung weight,lung index,FVC,PEF,FRC,Cdyn,and alveolar numbers(P<0.05,P<0.01),along with significant decreases in PIF,RL values,and mean alveolar septal thickness(P<0.01).However,in the Morris water maze experiment,compared with the model group,the electroacupuncture shallow needling group demonstrated significantly more platform crossing times and a higher target quadrant time percentage and target quadrant path percentage(P<0.01),coupled with reduced latency period(P<0.01),whereas the dexamethasone group showed no significant differences compared to the model group.Compared to the electroacupuncture shallow needling group,the dexamethasone group showed significantly less platform crossing times and a lower target quadrant time percentage and target quadrant path percentage,coupled with increased latency period(P<0.01).Conclusion Both electroacupuncture and dexamethasone demonstrated protective effects on lung development in PNE offspring rats by ameliorating lung histomorphology and pulmonary function.However,offspring receiving late,small-dose,short-course dexamethasone exhibited inferior learning and memory capabilities,whereas the electroacupuncture group showed significantly superior cognitive performance compared to the dexamethasone group.

Objective:To examine the long-term efficacy and complications of fecal microbiota transplantation (FMT) for the treatment of diseases related to intestinal dysbiosis.Methods:This was a retrospective descriptive study. Relevant data were collected from the records of 15 000 patients who had undergone FMT and been followed up for more than 3 months during the period from May 2017 to September 2024. The patient cohort comprised 3746 male and 11 254 female patients aged (45.3±12.2) years. The inclusion criterion was meeting the indications for FMT. Application of this criterion yielded 8258 patients with constipation, 684 with Clostridium difficile infection, 1730 with chronic diarrhea, 510 with inflammatory bowel disease, 432 with radiation enteritis, 1940 with irritable bowel syndrome, 365 with autism, 870 with postoperative gastrointestinal dysfunction, and 211 with neurodegenerative diseases. The three routes of delivering FMT comprised infusion of an enterobacterial solution through a nasoenteric tube into the jejunum for 6 consecutive days (upper gastrointestinal FMT group, 11 125 patients), oral intake of enterobacterial capsules for 6 consecutive days (oral capsule FMT, 3597 patients), and a single injection of a bacterial solution into the colon via colonoscopy (lower gastrointestinal FMT group, 278 patients). Other treatments were discontinued during the treatment and follow-up period and administration of other medications was not recommended unless absolutely necessary. The primary outcomes were the efficacy of FMT after 3, 12 and 36 months of treatment, and improvement in chronic constipation, C. difficile infection, chronic diarrhea, inflammatory bowel disease, radiation enteritis, irritable bowel syndrome, post-surgery gastrointestinal dysfunction, and autism. Other outcomes included the occurrence of short-term (within 2 weeks after treatment) and long-term (within 36 months after treatment) adverse reactions.Results:At 3, 12 and 36 months after treatment, the overall rates of effectiveness of treatment were 71.8% (10 763/15 000), 64.4% (7600/11 808) and 58.8% (3659/6218), respectively. Specifically, the rates of clinical improvement were 70.3% (5805/8258), 62.6% (3970/6345), and 56.5% (1894/3352), respectively, for constipation; 85.8% (587/684), 72.3% (408/564), and 67.3% (218/324), respectively, for C.difficile infection; 81.0% (1401/1730), 78.1% (1198/1534), and 72.3% (633/876), respectively, for chronic diarrhea; 64.3% (328/510), 52.3% (249/476), and 46.6 % (97/208), respectively, for inflammatory bowel disease; 77.3% (334/432), 65.4% (212/324), and 53.6% (82/153), respectively, for radiculitis; 70.6% (1370/1940), 64.5% (939/1456), and 60.4% (475/786), respectively, for irritable bowel syndrome; 75.3% (275/365), 70.0% (201/287), and 63.6% (112/176), respectively, for autism; 65.3% (568/870), 54.3% (355/654), and 46.5% (114/245), respectively, for post-surgical gastrointestinal dysfunction; and 45.0% (95/211), 40.5% (68/168), and 34.7% (34/98), respectively, for neurodegenerative diseases. At 3, 12, and 36 months post-treatment, clinical improvement rates were 77.1% (8580/11 125), 67.1% (6437/9595), and 62.1% (3196/5145), respectively, in the upper gastrointestinal route group; and 57.3% (2062/3597), 53.6% (1115/2081), and 45.0% (453/1006), respectively, in the oral capsule group; and 43.5% (121/278) , 36.4% (48/132) and 14.9% (10/67), respectively, in the lower gastrointestinal route group. No serious adverse reactions occurred during treatment or follow-up. The most common adverse reactions in the upper gastrointestinal route group, oral capsule group, and lower gastrointestinal route group were respiratory discomfort (20.4%, 2269/11 125), nausea and vomiting on swallowing the capsule (7.6%, 273/3597), and diarrhea (47.5%, 132/278), respectively; these symptoms resolved at the end of treatment. At 36 months of follow-up, 19 patients reported exacerbation of symptoms of pre-existing diseases and there had been 16 deaths that were not directly related to FMT. Additionally, no systemic diseases had developed after FMT.Conclusion:FMT for the treatment of intestinal dysfunction associated with disorders of the intestinal flora and related extraintestinal diseases is effective and not associated with serious adverse events.

Objective:To investigate the effects of multimodal and multisensory stimulation training on feeding-swallowing and neurological functions in stroke patients with dysphagia.Methods:Stroke patients with dysphagia treated at Henan Provincial People's Hospital from January 2023 to October 2024 were enrolled. Patients were randomly divided into three groups according to the random number table method, with 36 patients in each group. These three groups underwent different interventions for a period of 8 weeks: multisensory stimulation intervention (stimulation group), multimodal rehabilitation training intervention (rehabilitation group), and innovative multimodal and multisensory stimulation training intervention (combined group). The Kubota water swallow test and functional oral intake scale (FOIS) were used to assess the effective improvement rate of feeding function. Differences in scores of modified Mann assessment of swallowing (MMASA), swallowing quality of life (SWAL-QOL), and National Institute of Health Stroke scale (NIHSS) among the three groups were compared before intervention, and at 4 and 8 weeks post-intervention. SPSS 27.0 software was used to analyze the data by one-way ANOVA, repeated measures ANOVA, Kruskal-Wallis H test, Mann-Whitney U test and Pearson correlation analysis. Results:(1) After 8 weeks of intervention, the effective improvement rates of feeding function were 75.00%(27/36) and 72.22%(26/36) in the stimulation group and rehabilitation group, respectively, which were both lower than that in the combined group (94.44%(34/36), both P<0.05). (2) The interaction effect between time and group was significant in MMASA scores among the three groups before and after intervention ( F=2.569, P<0.05). MMASA scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, MMASA scores in the combined group (85.64±11.26, 92.56±10.55) were higher than those in the stimulation group (73.52±12.65, 82.97±12.84) and rehabilitation group (72.47±11.38, 84.39±12.29) (all P<0.05). (3) The interaction effect between time and group was significant in SWAL-QOL total scores among the three groups before and after intervention ( F=18.561, P<0.05). SWAL-QOL total scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups ( P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, SWAL-QOL total scores in the combined group (115.64±9.26, 135.68±9.55) were higher than those in the stimulation group (108.42±8.65, 113.75±8.84) and rehabilitation group (108.37±8.38, 114.39±9.29) (all P<0.05). (4) The interaction effect between time and group was significant in NIHSS scores among the three groups before and after intervention ( F=7.890, P<0.05). NIHSS scores at 8 weeks post-intervention were lower than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also lower than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, NIHSS scores in the combined group (8.36±1.35, 5.22±1.05) were lower than those in the stimulation group (11.65±2.11, 8.78±1.12) and rehabilitation group (11.32±2.03, 8.36±1.17) (all P<0.05). Conclusion:Multimodal and multisensory stimulation training can improve feeding-swallowing function and neurological impairment in stroke patients with dysphagia, with intervention effects superior to those of either approach used alone.
