Polygonatum sibiricum， as a traditional Chinese medicine with both medicinal and edible properties， has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs， tonifying the spleen and benefiting Qi， and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system， effectively enhancing and improving the morphology and function of immune organs， stimulating the proliferation and activation of immune cells， and regulating the secretion and release of immune factors， thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum， there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore， this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years， and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects： including increasing the organ index of the spleen and thymus， increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells， improving intestinal flora imbalance， regulating the quantity and proportion of T lymphocyte subsets， increasing the level of immunoglobulin， promoting the proliferation of macrophages， enhancing the activity of natural killer cells， increasing the number of white blood cells， and promoting the maturation of dendritic cells， providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum， and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

Objective:To explore the latent class characteristics of demoralization in severely disabled stroke patients, and analyze the differences and influencing factors of each class by latent class analysis.Methods:Convenience sampling was used to select 335 patients in the Neurointensive Care Unit of three Class Ⅲ Grade A hospitals in Anhui Province from October 2023 to March 2024, and were confirmed to be with post-stroke disability through follow-up as research subjects. General Information Questionnaire and Demoralization Scale-Ⅱ were used for a survey. Latent class analysis was used to identify latent classes of demoralization, and multiple logistic regression was used to analyze the influencing factors of different latent classes.Results:A total of 335 questionnaires were distributed, and 321 valid questionnaires were retrieved. The effective recovery rate of the questionnaires was 95.8%. Demoralization of severe stroke patients with disability was classified into four categories of low demoralization (40.2%, 129/321), moderate demoralization with coping loss (12.1%, 39/321), moderate demoralization with goal loss (21.2%, 68/321), and high disability (26.5%, 85/321). Multiple Logistic regression analysis showed that age, gender, per capita monthly income of the family, whether was the economic pillar of the family, long-term residence, and relationship with cohabitants were the influencing factors of demoralization in severe stroke patients with disability (all P<0.05) . Conclusions:There are four latent classes of demoralization in stroke patients with disability, and age, gender, per capita monthly income of the family, whether they are the economic pillar of the family, long-term residence, and relationship with cohabitants are the influencing factors of demoralization in severe stroke patients with disability.

Objective:To carry out evidence-based practice in the management of exercise rehabilitation for kinesiophobia patients after degenerative lumbar spine disease surgery, construct review indicators, analyze barriers and facilitators to evidence-based practice, and develop strategies for action change.Methods:Using the integrated-promoting action on research implementation in health services model (i-PARIHS model) as a theoretical framework, clinical nursing problems were identified, the evidence-based practice group was built, evidence was systematically retrieved, evaluated, and summarized, and review indicators were developed and review methodology was clarified. An evidence-based baseline review of 36 healthcare professionals in the Department of Orthopedics of the First Affiliated Hospital of Bengbu Medical University was conducted from October 2023 to January 2024 using the Evidence-based Readiness Scale. Barriers and facilitators to the evidence-based practice were analyzed based on the results of the baseline review, strategies for action were developed accordingly.Results:A total of 23 pieces of best evidence were included and 32 review indicators were developed. In the baseline review, 25 of the review indicators had an accurate implementation rate of < 60% and 14 had an implementation rate of 0. The main barriers of evidence-based practice were lack of effective feedback systems, lack of kinesiophobia mentoring programs, and lack of management processes and educational materials. The main facilitators were active support from organizational leadership and high motivation of patients and their families to participate. A total of 15 action strategies were eventually developed.Conclusions:This study constructed review indicators for the management of exercise rehabilitation in kinesiophobia patients after degenerative lumbar spine disease surgery based on the best evidence. There are several barriers in clinical practice. The action change strategy developed is scientifically sound and feasible.

Objective:To systematically evaluate patients' experience of receiving home parenteral nutrition (HPN) , and to provide a reference for improving patients' quality of life and developing relevant clinical nursing measures.Methods:Qualitative studies on patients' experiences, feelings and needs for HPN were electronically searched in PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, Wanfang Data, and VIP.

Objective:To evaluate the interaction between remimazolam and propofol for sedation during hysteroscopy.Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 20-45 yr, with body mass index of 18-28 kg/m 2, scheduled for elective hysteroscopy, were included. The test was conducted in two steps. Up-and-down sequential allocation was used to determine the median effective dose (ED 50) of remimazolam (group A) and propofol (group B). The ED 50 obtained in A and B groups were then used as the standard to determine the combination regimen in group C (0.25×ED 50 of remimazolam+ 0.75×ED 50 of propofol as the initial dose), in group D (0.5×ED 50 of remimazolam+ 0.5×ED 50 of propofol as the initial dose), and in group E (0.75×ED 50 of remimazolam+ 0.25×ED 50 of propofol as the initial dose). Up-and-down sequential allocation was used to determine the ED 50 of propofol when propofol and remimazolam were combined in C, D and E groups. The interaction between the sedative effects of two drugs was analyzed using the isobolographic analysis method, and the interaction coefficient and synergistic dose ratio of two drugs were calculated. Results:The ED 50 of remimazolam was 0.180 mg/kg in group A, and the ED 50 of propofol was 1.167 mg/kg in group B. The results of isobolographic analysis showed that remimazolam and propofol had a synergistic effect. When remimazolam 0.045, 0.090 and 0.135 mg/kg were combined with propofol 0.546, 0.288 and 0.160 mg/kg, the interaction coefficients were 1.393, 1.339 and 1.127 respectively. The synergistic dosage ratio of remimazolam and propofol was 1.0∶(3.2 to 12.0). Conclusions:Remimazolam and propofol have a synergistic effect on sedation when used for hysteroscopy, and the dose ratio is 1.0∶(3.2-12.0).

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.
