Objective: To summarize the best evidence for the management of patients with gastrointestinal graft-versushost disease after hematopoietic stem cell transplantation, and provide evidence-based references for clinical nursing work. Methods: A systematic search was conducted for relevant evidence on the management of patients with gastrointestinal graft-versus-host disease after hematopoietic stem cell transplantation from domestic and foreign databases, as well as websites of blood and bone marrow transplantation related societies. The search period was from the establishment of the database until February 2026. Results: After screening, a total of 19 articles were included, encompassing 3 clinical decisions, 1 recommended practice, 4 guidelines, 7 expert consensuses, and 4 evidence summaries. Twenty-five pieces of best evidence were summarized across 8 aspects: multidisciplinary collaboration, influencing factors, assessment and monitoring, diagnostic differentiation, symptom management, dietary nutrition, medication guidance, and health education. Conclusion: Summarizing the relevant evidence on the management of patients with gastrointestinal graft-versus-host disease after hematopoietic stem cell transplantation can provide evidence-based support for clinical medical staff, and it is recommended to apply it in combination with clinical practice and patient wishes.

Objective:To investigate the pain intensity,location and relationship between pain and foot-ankle function in patients with functional ankle instability(FAI).Method:From September 2022 to July 2023,163 FAI patients were assessed at Beijing Tongren Hospital,with ankle pain location,pain intensity(visual analogue scale,VAS),and foot-ankle function(American or-thopedic foot and ankle society ankle and hindfoot score,AOFAS)scores recorded.The VAS and AOFAS of various pain locations and the number of pain locations was compared across groups.Multiple linear regression was used to examine the association between the number of pain locations,VAS,and AOFAS.Result:Out of 163 FAI patients,150 reported the pain.Among them,37.33％had pain in a single location,34％in two locations,and 28.67％in multiple locations(＞2).The most common pain locations were the sinus tarsi(32％)and the anterior talofibular ligament(31％).There were no significant differences in VAS and AO-FAS among different pain locations in FAI patients with the same number of pain locations(P＞0.05).The VAS of FAI patients with multi-location pain(＞2 regions)was higher than that of patients with single-loca-tion pain and 2-location pain(P＜0.01),whereas the AOFAS was lower(P＜0.05).The number of pain loca-tions and VAS were negatively correlated with AOFAS score(P＜0.05),which could predict 20.9％of the AO-FAS score.Conclusion:The majority of FAI patients experience pain,and the pain intensity and number of pain loca-tions impact foot and ankle function.When establishing and implementing rehabilitation strategies for FAI pa-tients,pain relief and minimizing the number of pain locations should be emphasized.Future research should investigate effective pain management measures to improve ankle function in patients with FAI at specific loca-tions with a high incidence(e.g.,tarsal sinus,anterior talofibular ligament).

Objective:To explore the potential risk factors for cancer in patients with adenomatous polyps based on tumor markers and polyp lesion characteristics.Methods:A retrospective analysis was conducted to collect clinical data of 115 patients with adenomatous intestinal polyps who visited Nanjing Jiangbei Hospital from November 2022 to November 2024. They were divided into a cancerous group (17 cases) and a non cancerous group (98 cases) based on whether they were cancerous or not. Clinical data such as tissue type and polyp site and tumor marker levels such as carcinoembryonic antigen (CEA) and cancer antigen 72-4 (CA72-4) were collected at the first visit of all patients. The potential risk factors of adenomatous intestinal polyp canceration were investigated by Logistic regression analysis.Results:Univariate analysis revealed that the proportion of villous tubular adenomas, central depression of polyps, and lobulated polyps in the cancerous group were higher than those in the non cancerous group. Serum levels of CEA and CA72-4 were also higher in the cancerous group than in the non cancerous group : 13/17 vs.47.96% (47/98), 7/17 vs. 15.31% (15/98), 6/17 vs. 8.16% (8/98), (6.41 ± 1.81) μg/L vs. (4.23 ± 1.48) μg/L, (6.98 ± 1.83) kU/L vs. (5.66 ± 1.78) kU/L, respectively. The difference was statistically significant ( P<0.05). The results of Logistic regression analysis showed that the histological subtype of villous tubular adenoma, central depression of polyps, lobulated polyps, and high levels of CEA and CA72-4 were independent risk factors for cancer in patients with adenomatous intestinal polyps ( P<0.05). A nomogram risk model was constructed based on the influencing factors of canceration in patients with adenomatous intestinal polyps. The calibration curve was drawn, and the calibration curve was similar to the Y-X straight line, suggesting that the evaluation results of the nomogram risk model were highly consistent with the actual observation results. The receiver operating characteristic (ROC) curve was drawn. The results showed that the area under the curve (AUC) of the nomogram risk model for evaluating the canceration of patients with adenomatous intestinal polyps was 0.956, and the evaluation value was high. The decision curve was drawn, with the threshold of high risk as the horizontal coordinate and the net rate of return as the vertical coordinate. The results showed that when the threshold was in the range of 0 - 0.85, 0.96 - 0.99, the net benefit rate of predicting the cancer risk of patients with adenomatous intestinal polyps was greater than 0 and the maximum net benefit rate was 0.148. Conclusions:The histological classification of villous tubular adenoma, central depression of polyps, lobulated polyps, and high levels of CEA and CA72-4 are independent risk factors for cancer in patients with adenomatous intestinal polyps; The evaluation efficiency of the column chart risk model constructed based on the above factors is good.

Objective To explore the characteristics and molecular mechanisms of dynamic changes in ovarian function during natural aging in mice.Methods Eighteen female ICR mice of 2,6,10 and 14 months of age(referred to as 2 M,6 M,10 M,and 14 M)were included.The estrous cycle,ovarian index,pregnancy rate and embryo number were detected.The number of follicles was observed using HE staining.Serum anti-Müllerian hormone(AMH)levels were measured using ELISA.Protein and mRNA expression of P16,P21,proliferator-activated receptor-γ coactivator-1α(PGC-1α),and mitochondrial transcription factor A(TFAM)were detected through IHC and qPCR,respectively,and the protein expression of PGC-1α and TFAM was detected by Western blot.Relationships between indicators were evaluated based on Spearman's rank correlation coefficients and logistic regression analyses.Results Compared with estimates in the 2 M group,the percentage of estrous cycle disorders(P＜0.05 in 10 M group,P＜0.01 in 14 M group),ovarian index(P＜0.05 in 10 M group,P＜0.01 in 14 M group),serum AMH level(P＜0.01 in 10 M group,P＜0.01 in 14 M group),number of embryos(P＜0.01 in the 10 M group,P＜0.01 in 14 M group),and pregnancy rate(P＜0.01 in 14 M group)were significantly lower;the number of follicles at all levels and total number of follicles were lower(all P＜0.01),and the number of atretic follicles(all P＜0.01)was higher.Furthermore,P16 and P21 mRNA(P16:P＜0.01 in 10 M and 14 M groups;P21:P＜0.05 in 10 M group,P＜0.01 in 14 M group)and protein levels(P16:P＜0.01 in each group;P21:P＜0.01 in 10 M and 14 M groups)were elevated.Spearman's correlation analyses showed that the age in months was negatively correlated with the ovarian index,serum AMH level,primordial follicle number,number of embryos,and expression of PGC-1αand TFAM and positively correlated with the expression of atretic follicle,P16 and P21(all P＜0.01).Logistic regression analysis revealed a significant negative correlation between the age in months and pregnancy rate(P＜0.01).PGC-1α mRNA was significantly decreased(all P＜0.01),and TFAM mRNA was significantly decreased in 10 M and 14 M groups(P＜0.01).PGC-1α levels were significantly decreased in the 10 M group(IHC:P＜0.05;Western blot:P＜0.01)and 14 M group(all P＜0.01);TFAM levels were significantly lower in 6 M,10 M,and 14 M groups than in the 2 M group(IHC:P＜0.01;Western blot:P＜0.01).Compared with the 2 M group,expression levels of PGC-1α and TFAM were positively correlated with the ovarian index and serum AMH level and negatively correlated with P16 and P21 expression(all P＜0.01).Conclusions Ovarian function in mice declines progressively with age in months,as reflected by reductions in follicles and fertility and the up-regulation of aging markers,which may be associated with the decreased expression of the mitochondrial biogenesis factors PGC-1α and TFAM.

Objective:To explore the efficacy of a bleeding risk graded management program in patients with lower extremity deep vein thrombosis (DVT) undergoing catheter-directed thrombosis (CDT) .Methods:Convenience sampling was used to select 100 DVT patients who underwent CDT from October 2021 to December 2023 in the Nanjing First Hospital as study subjects. According to the propensity matching score ratio of 1: 1, patients were divided into control group and observation group, with 50 cases in each group. Control group implemented CDT routine nursing and rehabilitation exercises, and observation group implemented a bleeding risk graded management program based on control group by dynamically monitoring changes in plasma fibrinogen and blood pressure. Differences in the rates of swelling reduction in the limbs, venous patency, bleeding events and hospitalization satisfaction were compared between the two groups.Results:After the intervention, the swelling reduction rate of the limbs of DVT patients in observation group was (85.07±11.96) %, and the rate of venous patency was (89.00±25.33) %, and that of control group was (70.85±21.73) %, (75.00±35.36) %, and the differences were statistically significant (all P<0.05). The rate of bleeding events was lower in the observation group than in the control group, and the difference was statistically significant ( P<0.05). The difference in hospitalization satisfaction between the two groups was not statistically significant ( P>0.05) . Conclusions:The bleeding risk graded management program developed after comprehensive assessment can realize the balance between the therapeutic benefit and bleeding risk of CDT for DVT patients, and can improve the safety and effectiveness of CDT.

Chronic visceral pain is a persistent and debilitating condition arising from dysfunction or sensitization of the visceral organs and their associated nervous pathways. Increasing evidence suggests that imbalances in central nervous system function play an essential role in the progression of visceral pain, but the exact mechanisms underlying the neural circuitry and molecular targets remain largely unexplored. In the present study, the ventral tegmental area (VTA) was shown to mediate visceral pain in mice. Visceral pain stimulation increased c-Fos expression and Ca²⁺ activity of glutamatergic VTA neurons, and optogenetic modulation of glutamatergic VTA neurons altered visceral pain. In particular, the upregulation of NMDA receptor 2A (NR2A) subunits within the VTA resulted in visceral pain in mice. Administration of a selective NR2A inhibitor decreased the number of visceral pain-induced c-Fos positive neurons and attenuated visceral pain. Pharmacology combined with chemogenetics further demonstrated that glutamatergic VTA neurons regulated visceral pain behaviors based on NR2A. In summary, our findings demonstrated that the upregulation of NR2A in glutamatergic VTA neurons plays a critical role in visceral pain. These insights provide a foundation for further comprehension of the neural circuits and molecular targets involved in chronic visceral pain and may pave the way for targeted therapies in chronic visceral pain.
