The pathogenesis of ulcerative colitis(UC)is still unclear,and the pathogenesis based on intestinal mucosal immune imbalance is now widely recognized."Spleen as the defense"refers to the function of the spleen to protect the body and defend against pathogenic factors,which is highly consistent with modern mucosal immunology theory.The abnormal function of"Spleen as the defense"is the key reason for the immune imbalance of UC intestinal mucosa.In this paper,"spleen as the defense"as the starting point,to explore the mechanism of UC intestinal mucosal immune dysfunction,to consolidate the theoretical basis for the treatment of UC based on spleen,and to provide a theoretical basis for the treatment of UC from the perspective of restoring intestinal mucosal immune homeostasis.

Objective To understand the current status and hot spots of research on spleen deficiency syndrome of functional dyspepsia in China,and to provide reference for clinical treatment and mechanism research of this disease.Methods Research literature on spleen deficiency syndrome of functional dyspepsia included in the three major Chinese databases CNKI,Wanfang database and VIP from January 1,2000 to June 16,2023 were searched and manually screened.NoteExpress 3.6.0.9220 was used to screen duplicate research literature and manage them,and CiteSpace 5.7.R5 software was applied to draw cooperative network graphs and tables of authors and their research institutions,construct co-occurrence network graphs and tables of keywords,emergent graphs,clustering network graphs and tables,and clustering timeline graphs,and analyze them one by one.Results A total of 407 research papers on spleen deficiency in functional dyspepsia were included,with an overall fluctuating upward trend in the number of annual publications;the high-producing authors were Tang Xudong,Lv Lin,Wang Fengyun,Zhang Shengsheng,Huang Suiping,Yin Xiaolan,and Ma Xiangxue in order;the research institutions with more publications were Beijing University of Traditional Chinese Medicine,Hunan University of Traditional Chinese Medicine,Xiyuan Hospital of the Chinese Academy of Traditional Medicine,Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University,and the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine,in order;The high-frequency keywords were"functional dyspepsia","liver depression and spleen deficiency","spleen deficiency and qi stagnation","Chinese medicine therapy","clinical research","spleen deficiency syndrome",etc.Accordingly,a list of high-centered keywords(centrality≥0.1),the top 20 emergent words,14 clustering labels and a timeline diagram of research literature were generated.Conclusion The research direction of functional dyspepsia spleen deficiency in China is mainly focused on three aspects:TCM syndrome type,clinical research and mechanism research.

Objective To construct and apply an intelligent follow-up information system for patients with cancer pain,providing references for improving the efficiency of hospital follow-up and promoting pain management of patients at home.Methods The intelligent discharge follow-up system for patients with cancer pain includes 2 platforms,namely a patient self-report platform and an administrator operation platform.The administrator operation platform consists of 5 modules,namely the workbench module,the follow-up plan module,the follow-up results module,the health education module and the data statistics module.In January 2022,the system was officially put into clinical application.The use of the system was analyzed,and patients'completion rate,medication compliance,incidence of moderate and severe pain and satisfaction with pain control were compared before(from January 2020 to December 2021)and after(from January 2022 to November 2023)the application of the system.Results At present,this system has been applied in 95 cancer-related wards of our hospital.From January 2022 to November 2023,the number of people who should be followed up was 4 248,and the number of people who actually completed the follow-up was 4 127;the rate of follow-up completion was 97.2%;the rate of timely completion of the follow-up was 94.9%;the rate of automatic follow-up by the system was 40.1%;the rate of patient abnormality report was 31.9%;the rate of timely treatment of patient abnormality report was 89.1%.After the application of the system,the completion rate of pain follow-up was increased,and the difference was statistically significant(P<0.001).After the application of the system,the medication compliance rate of patients with cancer pain increased from 86.9%to 91.0%;the incidence of moderate and severe pain decreased from 6.8%to 5.2%;the satisfaction with pain control increased from 81.0%to 83.5%(P<0.05).Conclusion The intelligent discharge follow-up system for patients with cancer pain can effectively improve the discharge follow-up efficiency and promote the management of patients with cancer pain at home.

Pemphigus is a group of life-threatening chronic autoimmune bullous diseases. It is currently believed that the humoral immunity mediated by anti-desmoglein IgG antibodies is the primary mechanism underlying the occurrence of pemphigus. However, recent studies have indicated a critical role of various T cell subsets in the occurrence of pemphigus.

OBJECTIVE The abnormal amyloid-β(Aβ)and oxidative stress assiociated with the progression of Alzheimer disease(AD).Quercetin has been reported to possess antioxidant and anti-inflammatory properties in neurodegenerative disorders.In this present study,we designed to characterize the mechanisms by which quer-cetin exerts neuroprotective effects in murine neuroblas-toma N2a cells stably expressing human Swedish mutant amyloid precursor protein(N2a/APP).METHODS N2a/APP cells were treated with quercetin at concentrations of 10,20 and 50 μ mol·L-1 for 24 h.Cell viability was examined with CCK-8 assays.The protein levels of ERK1/2 and Akt were detected by Western blotting.Intra-cellular reactive oxygen species(ROS)was detected by a fluorescent probe 2,7-dichlorofluorescein diacetate(DCFH-DA).The mitochondrial membrane potential(Δψ m)in N2a/APP cells was detected by using JC-1 staining method.Immunofluorescence was used to detect the generation of 8-hydroxy-2′-deoxyguanosine(8-OHdG)and 4-hydroxynonenal(4-HNE).RESULTS Quercetin attenuated the enhancement of p-ERK1/2,reductions of p-Akt,and decreased levels of APP expression.More-over,quercetin alleviated loss of mitochondria membrane potential(MMP)since it attenuates these oxidative stress,as reflected in the levels of ROS,4-HNE and 8-OHdG,was elevated in N2a/APP cells and these effects were again ameliorated by quercetin.CONCLUSION Neuroprotection by quercetin in N2a/APP cells involves normalizing the impaired mitochondrial function and reducing oxidative stress via inactivation of the ERK1/2 and activation of the Akt pathways.

Objective:To investigate the change of D-Dimer (D-D), cardiac troponin I (cTnI) and vasoactive-inotropic score (VIS) after Stanford type A aortic dissection (TAAD) and thier predictive effect on death outcome.Methods:120 patients with TAAD who were treated in the Affiliated Hospital of Jining Medical College from January 2019 to January 2022 were retrospectively selected and divided into death group ( n=17) and survival group ( n=103) according to the 28-day survival after operation. The difference of clinical data between the two groups was compared, and the influencing factors of postoperative death in TAAD patients were analyzed by logistic regression method. Results:The age, deep hypothermic circulatory arrest time, D-D and cTnI of the patients in the death group were (60.50±5.42)years old, (30.40±9.92)min, (15.65±5.52)g/L and (3.32±0.82)mg/L, respectively, which were significantly higher than those in the survival group (all P<0.05). The VIS score and change of VIS score in the death group at 24 hours after operation were (9.66±1.10)points and (4.50±0.91)points respectively, which were significantly higher than those in the survival group (all P<0.05). Logistic regression analysis showed that age, D-D, cTnI and change of VIS score were the influencing factors of death after TAAD (all P<0.05). The area under the receiver operating characteristic (ROC) curve predicted by the D-D, cTnI and change of VIS score for death in TAAD patients was 0.718, 0.691 and 0.789 respectively (all P<0.05). Conclusions:Postoperative death of TAAD patients is affected by their age, D-D, cTnI and change of VIS score. The D-D, cTnI and change of VIS score have certain application value in predicting postoperative death of patients.
