Inflammatory bowel disease is a chronic, idiopathic, and recurrent gastrointestinal disorder with an unclear etiology and uncertain pathogenesis. Traditional treatment strategies rely on frequent administration of high doses of medication to reduce inflammation, whereas these approaches have limitations and may induce potential complications. Therefore, finding more effective and safe therapeutic drugs and methods is particularly important. Plant-derived exosome-like nanovesicles(PDELNs) are nano-sized vesicles with a lipid bilayer structure that are secreted by plant cells. The bioactive molecules contained within, such as lipids, proteins, and nucleic acids, can serve as information carriers, playing a role in the transmission of information and substances between cells and across species. PDELNs can carry and transfer their own bioactive substances or act as carriers for delivering other active components or drugs. Due to the high biocompatibility, low toxicity, and significant bioactivity, PDELNs have garnered widespread attention. Compared with other exosomes, PDELNs are not destroyed in the gastrointestinal tract when taken orally and can reach the intestines. This unique property makes PDELNs a promising oral nanodrug for treating intestinal diseases, showing great potential in this area. This article reviews recent research literature on PDELNs regarding the physicochemical characteristics, extraction and purification methods, functions, application characteristics and mechanisms in the treatment of intestinal diseases, and use as a carrier for treating intestinal diseases, aiming to provide a reference for the use of PDELNs in the treatment of intestinal diseases.

Objective To evaluate the efficacy and safety of botulinum toxin A (BTX-A) injection into the external urethral sphincter in combination with sacral neuromodulation (SNM) for the treatment of idiopathic non-obstructive urinary retention (INOUR). Methods A total of 57 INOUR patients treated in our hospital during May 2022 and May 2024 were enrolled. Patients were divided into the BTX (n=30) and combined groups (n=27) according to whether they chose SNM after BTX-A injection. The baseline, postoperative 1-month and 6-month consecutive 3-day voiding diaries, quality of life score (QoL), and post-void residual (PVR), preoperative and postoperative 1-month urodynamic results, and postoperative complications were recorded and compared between the two groups. Results One month after surgery, the average number of voiding frequency per day and PVR were lower in both groups than those before surgery (P<0.05), while the average daily urine volume and maximum flow rate (MFR) were higher (P<0.05). There was no statistically significant difference between the maximum detrusor pressure during micturition in both groups before and after surgery (P>0.05). One month after surgery, the average number of voiding frequency per day, average daily urine volume, PVR, QoL, MFR, bladder compliance (BC), and maximum cystometric capacity (MCC) were better in the combined group than in the BTX group (P<0.05), and the efficiency was higher in the combined group (88.9% vs.63.3%, P<0.05). Six months after surgery, the efficacy of the BTX group returned to the baseline level with no statistically significant difference, whereas the efficacy of the combined group was stable (not different from the postoperative 1-month indicators, but better than the baseline level). During the follow-up, there was no difference in the incidence of complications between the BTX group and combined group [43.3% (13/30) vs. 48.1% (13/27), P>0.05]. Conclusion BTX-A injection into the external urethral sphincter combined with SNM improves the short-term outcomes of INOUR patients and maintains the efficacy 6 months postoperatively, which is a safe and reliable treatment option.

OBJECTIVE: To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective. METHODS: Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ₊TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction. RESULTS: TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45⁺ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01). CONCLUSIONS TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.

Objective:To explore the expression and clinical significance of heme oxygenase-1 (HO-1) and quinone oxidoreductase (NQO-1) in children with different severity levels of mycoplasma pneumoniae (MP) infection.Methods:A total of 140 children with MP infection who were treated at the Affiliated Hospital of Jining Medical University from January to June 2022 were selected as the observation group, while 100 healthy children who underwent physical examination were selected as the control group. The serum levels of interleukin-2 (IL-2), IL-6, IL-10, IL-1β, tumor necrosis factor α (TNF-α), interferon γ (IFN-γ), HO-1, and relative expression of NQO-1 protein were compared between the control group and the observation group, as well as between children with different degrees of MP infection, Forced vital capacity (FVC), maximum expiratory volume in the first second (FEV 1), peak expiratory flow rate (PEF), 50% forced expiratory flow rate and maximum mid expiratory flow rate (MEF 25-70), 50% forced expiratory flow rate (MEF 50), and 25% forced expiratory flow rate (MEF 25). Pearson correlation method was used to analyze the correlation between the expression of HO-1 and NQO-1 with inflammatory factors and lung function indicators. The receiver operating characteristic (ROC) curve was used to analyze the value of HO-1 and NQO-1 expression in predicting severe MP. Results:The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group were significantly higher than those in the control group (all P<0.05), while the relative expression level of NQO-1 protein was significantly lower than that in the control group ( P<0.05). The FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 in the observation group were significantly lower than those in the control group (all P<0.05). The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group of severe children were significantly higher than those in mild children (all P<0.05), while the relative expression of NQO-1 protein, FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 were significantly lower than those in mild children (all P<0.05). HO-1 in children with MP infection is positively correlated with IL-6, IL-1β, and IFN-γ, while the relative expression level of NQO-1 protein is negatively correlated with IL-6, IL-1β, and IFN-γ (all P<0.05); HO-1 was negatively correlated with MEF 50 and MEF 25, while the relative expression level of NQO-1 protein was positively correlated with MEF 50 (all P<0.05). The area under the ROC curve for predicting the relative expression levels of HO-1 and NQO-1 proteins in severe MP was 0.871 and 0.934, respectively (all P<0.05). Conclusions:The expression of serum HO-1 and NQO-1 in children with MP infection is correlated with cytokines and lung function indicators, and has certain application value in predicting severe illness.

The connotation of theory of"toxin"in TCM is rich,and"toxin"is closely related to the occurrence and development of chronic liver disease.Treatment from"toxin"is an important treatment for chronic liver disease.In this article,by summarizing the ancient and modern literature to explain the theory of"toxin",and combined with clinical experience,it concluded that"toxin"has the pathogenic characteristics of strong bias,lingering nature,complex and changeable in chronic liver disease.The authors put forward the view that"toxin leads to disease occurrence and accelerates disease progression",and explored the idea of treating chronic liver disease from"toxin",including tracing the source of toxins,clarifying the nature of toxins,identifying changes of toxins,strengthening the body and eliminating toxins,in order to provide ideas for the clinical treatment of chronic liver disease.

Objective:To investigate possible neuromodulatory mechanisms involved in the involvement of parvalbu-min(PV)expression in the basal ganglia output nuclei,entopeduncular nucleus(EPN)and substantia nigra pars etic-ulata(SNr),in exercise-induced chronic fatigue impairs working memory capacity.Methods:Male SD rats were divid-ed into control group and Fatigue group by random number method,and a three-stage incremental load treadmill training program was selected to establish a chronic exhaustion exercise-induced fatigue rat model.The working memory ability of rats was assessed by the Y-maze autonomous alternation experiment.Immunohistochemical staining was used to ob-serve the expression of parvalbumin(PV)positive neurons and cysteine aspartate-specific protease-3(caspase-3)in EPN and SNr of rats.Results:The accuracy of voluntary alternation in the fatigue group was obviously lower than that in control group(P＜0.05).The results of immunohistochemical staining showed that the density of PV positive neu-rons and the degree of positive fiber staining in EPN and SNr in the fatigue group were obviously lower than those in the control group(P＜0.05,P＜0.01).The number of caspase-3 positive cells per unit area of EPN and SNr in the fa-tigue group was obviously higher than that in the control group(P＜0.05,P＜0.01).Conclusion:The mechanism of impairing working memory in rats caused by exercise-induced chronic fatigue may be related to the apoptosis of PV posi-tive neurons in EPN and SNr.
