To investigate the role of the DPP4-nestin axis in liver fibrosis induced by alveolar cyst infection,a murine model was established using C57BL/6 mice via hepatic portal vein injection.Liver histopathological changes were assessed using HE staining,while immunohistochemistry and immunofluorescence were employed to evaluate the expression levels of nestin and DPP4 in infected mouse livers.In vitro,J S1 cell line was stimulated with recombinant DPP4 protein to es-tablish a cellular model,and qPCR,Western blot,and shRNA lentivirus interference techniques were utilized to examine the involvement of the DPP4-nestin axis in hepatic stellate cell activation.The findings demonstrated that compared to the Sham group,liver tissue structure disruption and collagen deposition were evident along with significantly increased expressions of nestin and DPP4(P＜0.050 0),which colocalized with nesin and α-SMA.Furthermore,stimulation with recombi-nant DPP4 protein significantly enhanced JS1 cell activation(P＜0.050 0)as well as upregulated nestin expression(P＜0.050 0)when compared to control group cells.Notably,shRNA lentivirus-mediated inhibition of nestin expression effectively suppressed the activating effects exerted by re-combinant DPP4 protein on JS1 cells(P＜0.050 0).Collectively,these results highlight the crucial regulatory role played by the DPP4-nestin axis in hepatic stellate cell activation triggered by alveo-lar infection;thus,targeting this axis may represent a novel therapeutic strategy for treating alveo-lar infection-induced liver fibrosis.

Objective:To develop postoperative care plans based on intervention diagram for young and middle-aged postoperative glioma patients, and validate their effectiveness.Methods:A convenience sample of 68 young and middle-aged glioma patients who underwent surgery at Beijing Tiantan Hospital, Capital Medical University, between September 2023 and April 2024 was recruited. Patients were randomly assigned to either the intervention group or the control group (34 cases each) using a random number table. The control group received routine nursing care, while the intervention group received additional care based on the intervention diagram program. Self-perceived burden scores, psychological distress scores, and quality of life scores were compared between the two groups before the intervention and after one month.Results:Prior to the intervention, there were no statistically significant differences between the two groups in terms of total or dimensional scores of self-perceived burden ( P>0.05). After the intervention, the intervention group showed lower scores in all dimensions and total scores of self-perceived burden compared to the control group, with statistically significant differences ( P<0.05). Similarly, no significant differences were found between the two groups in psychological distress and quality of life scores before the intervention ( P>0.05) ; however, after the intervention, the intervention group demonstrated lower psychological distress and higher quality of life scores than the control group, with statistically significant differences ( P<0.05) . Conclusions:The intervention diagram-based program effectively reduces self-perceived burden and psychological distress, and enhances quality of life in young and middle-aged postoperative glioma patients.

Aim To explore the mechanism of action of Guizhi Jia Gegen decoction(GGD)in treating pneu-monia-enteritis induced by H1N1 influenza virus infec-tion in a mouse model,using network pharmacology and molecular docking techniques,followed by in vivo verification.Methods A pneumonia-enteritis mouse model was established,and the intervention effects of GGD on the model mice were evaluated using indica-tors such as body weight,rectal temperature,lung in-dex,colon length,H1N1 M gene expression,relative mRNA expression levels of inflammatory cytokines,and pathological sections of the lung and intestine.The targets of the blood-absorbed components of GGD were identified using the Swiss Target Prediction platform,and the disease targets were retrieved from the Gene-Cards platform.The intersecting targets were analyzed through PPI network analysis using the STRING data-base to identify core targets.GO analysis and KEGG pathway enrichment analysis were performed using the Metascape database.RT-qPCR was employed to vali-date the core targets and pathways.Molecular docking was conducted using AutoDock Tools software to verify the interactions between blood-absorbed components and key targets.Results GGD demonstrated signifi-cant therapeutic effects on the pneumonia-enteritis mouse model.The results of network pharmacology in-dicated that the therapeutic effects of GGD were strong-ly associated with targets such as TNF,ALB,PTGS2,MMP9,EGFR,ESR1,SRC,HSP90AA1,PPARG and MMP2.RT-qPCR results indicated that GGD could intervene in pneumonia-enteritis by regulating the targets TNF,ALB,EGFR and the related targets of the NF-κB pathway.Molecular docking results re-vealed that blood-absorbed components such as puerar-in and liquiritin could stably bind to TNF,ALB and EGFR.Conclusion Components such as puerarin and liquiritin in GGD may exert therapeutic effects on pneumonia-enteritis induced by H1N1 influenza virus infection by acting on targets such as TNF,ALB and EGFR.

Objective To investigate the anesthesia effects of different concentrations of sevoflurane combined with propofol during primary liver cancer resection surgery,as well as the changes in immune function in patients.Methods Using single-blind method,120 cases of primary hepatocellular carcinoma admitted to the Third Affiliated Hospital of Naval Military Medical University from January 2023 to September 2023 were prospectively selected as the study subjects,and the patients were randomly(using the randomized numerical table method)included in the control group(60 cases)and the observation group(60 cases).During hepatic cancer resection,the control group was given 0.5 alveolar minimum effective concentration(MAC)sevoflurane combined with propofol target-controlled infusion anesthesia,and the observation group was given 1.0 MAC sevoflurane combined with propofol target-controlled infusion anesthesia,and both groups were observed for 3 d postoperatively.The perioperative related indexes,the sedation and quality of awakening in the immediate moment of extubation,15 min after extubation,and 30 min after extubation,the cognitive function before and at 1 and 3 d postoperatively,vital signs before induction of anesthesia,after induction of anesthesia,at the moment of intubation,at the end of surgery,immune function before and 1 d postoperative,and adverse reactions during the observation period were compared between the two groups.Results The time for extubation,recovery of spontaneous respiration,recovery of orientation,and awakening in the observation group were(11.25±1.69)min,(9.76±1.34)min,(69.23±3.35)min,and(10.13±1.43)min,and the control group were(14.57±2.28)min,(13.55±2.76)min,(73.44±4.52)min,(14.26±2.25)min,all of which were shorter in the observation group than in the control group(P＜0.05).The Ramsay sedation score at the immediate moment of extubation was(4.16±0.22)in the observation group,and(3.21±0.10)in the control group;the standardized(Aldrete)score in the awakening room of the observation group at the immediate moment of extubation,and 15 min after extubation were(9.56±0.12)and(9.77±0.20),respectively,and the control group was(9.02±0.13),respectively,(9.05±0.17)points;the scores of the brief mental state examination(MMSE)scale in the observation group were(26.23±1.12)points and(25.17±0.98)points in the control group in the 1 d postoperative period,which were higher than those of the control group(P＜0.05).The heart rate(HR)at the moment of intubation and at the end of operation in the observation group were(73.08±4.10)beats/min,(75.27±6.03)beats/min,and the mean arterial pressure(MAP)was(81.56±4.49)mmHg and(86.07±5.48)mmHg,respectively,and in the control group the HR was(75.47±5.78)beats/min,(77.91±6.79)beats/min,and the MAP was(85.22±5.08)mmHg and(88.25±6.01)mmHg in the observation group,respectively,which were lower than those in the control group(P＜0.05).The whole blood natural killer(NK)cells,CD4+and CD4+/CD8+in the observation group at 1 d postoperatively were(35.62±5.54)％,(50.09±3.32)％,and(1.42±0.25),the control group were(24.12±4.09)％,(43.17±4.20)％,and(1.20±0.19),the observation group was higher than the control group(P＜0.05);whole blood CD8+was(26.55±3.02)％in the observation group and(28.71±4.45)％in the control group,the observation group was lower than the control group(P＜0.05).The total incidence of adverse reactions during the observation period was 16.67％in the observation group and 5.00％in the control group,which was higher than the control group(P＜0.05).Conclusion Compared with 0.5 MAC sevoflurane combined with propofol target-controlled infusion anesthesia,1.0 MAC sevoflurane combined with propofol target-controlled infusion anesthesia had less effect on hemodynamics and immune function in patients undergoing resection for primary hepatocellular carcinoma,and it could improve the quality of patients'awakening,cognitive function,and promote postoperative recovery,and the anesthesia was more effective,but it had more adverse effects.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

[Purpose]To analyze the survival of colorectal cancer patients in Jiashan County of Zhejiang Province from 1991 to 2020.[Methods]The data of newly reported cases of colorectal cancer were collected in Jiashan County from January 1,1991 to December 31,2020,and pa-tients were followed-up till December 2023.The observed survival rate(OSR)and relative survival rate(RSR)were calculated using the life table and Ederer Ⅱ method with 5-year intervals.Rela-tive survival was adjusted using the International Cancer Survival Standards.The Joinpoint re-gression model was used to calculate the average annual percentage change(AAPC)to analyze the change trend of survival rate.[Results]The 5-year RSR of colorectal cancer increased from 21.7％during 1991 to 1995 to 73.4％during 2016 to 2020,showing an increasing trend(AAPC=4.6％,P＜0.05),for men it increased from 17.7％to 72.7％and for women it increased from 30.0％to 74.3％,with AAPCs of 3.9％and 4.3％,respectively(P＜0.05).The 5-year RSR of colorectal can-cer in all age groups showed an increasing trend(P＜0.05 for all age groups,except for 75+),and the highest increase was found in the age group of 65～74 years old(AAPC=4.9％).[Conclusion]From 1991 to 2020,the 5-year survival rate of colorectal cancer in Jiashan County showed a steady increase,for women and those aged 65～74 years old the increase was more significant.The cancer screening of high-risk groups should be focused on to improve colorectal cancer survival rate.

Objective:To evaluate the application value of the Supply-Processing-Distribution(SPD)supply chain mode in the refined management for medical consumables in hospital on the basis of SPD supply chain mode.Methods:An integrated efficiency index system was constructed based on SPD,and the Analytic Hierarchy Process(AHP)and Entropy Method were used to determine index weights by combined weighting.Medical consumables were classified and managed according to the index weight values.A total of 63,461 types of medical consumables(included low-value medical consumables and high-value medical consumables)that was used in clinical practice at Beijing Anzhen Hospital,Capital Medical University from January to June 2021 and January to June 2023 were selected.In them,the 54,632 types of medical consumables that were used between January and June 2021 were managed by adopting conventional supply chain mode,while 56,471 types of medical consumables that were used(included 47,642 types of medical consumables that were managed by conventional supply chain made at the first stage,and 8,829 types of new medical consumables)between January and June 2023 were managed by adopting the SPD supply chain mode.The inventory amount,inventory quantity,loss rate,and return or change rate of medical consumables of the two management modes were compared.A self-designed satisfaction questionnaire was used to evaluate the satisfaction of medical staffs,who used these medical consumables,for the two kinds of management modes.Results:The inventory amount of low-value medical consumables that were managed by the SPD supply chain mode was(1,424.09±75.68)million CNY,which was lower than(2,290.79±215.93)million CNY of adopting conventional supply chain mode,with a statistically significant difference(t=8.85,P<0.05).The inventory amount of high-value medical consumables that were managed by the SPD supply chain mode was 0,which was lower than(7,692.32±360.53)million CNY of adopting conventional supply chain mode,with a statistically significant difference(Z=-2.201,P<0.05).The inventory quantities of both low-value and high-value medical consumables of adopting SPD supply chain mode were significantly lower than those of adopting conventional supply chain mode,with statistically significant differences(t=10.443,11.225,P<0.05).The average loss rates of both low-value and high-value medical consumables of adopting SPD supply chain mode were significantly lower than those of adopting conventional supply chain mode,with statistically significant differences(Z=-2.207,-2.201,P<0.05).The average return or change rates of both low-value and high-value medical consumables of adopting SPD supply chain mode were significantly lower than those of adopting conventional supply chain mode,with statistically significant differences(t=14.685,8.716,P<0.01).The satisfaction scores of medical staffs from different departments for medical consumables of adopting the SPD supply chain mode were higher than those of adopting conventional supply chain mode,with a statistically significant difference(t=7.674,P<0.05).Conclusion:The application of the SPD supply chain mode for medical consumables in hospital can reduce the inventory amount,inventory quantity,loss rate,and return or change rate of medical consumables,and improve the satisfaction of medical staffs.

Objective:To discern the association between autism-like behaviors and resilience within the ado-lescent demographic.Methods:A total of 7 063 middle school students were selected to assess ASD-like behaviors and resilience in adolescents using the Autism Spectrum Screening Questionnaire(ASSQ)as well as the Resilience Scale for Chinese Adolescent(RSCA).Subgroups bounded by P5 and P95 of the total ASSQ score,a comparative analysis of the resilience scores between these groups was executed.A correlation evaluation and linear regression a-nalysis was carried out between ASSQ and RSCA scores from all participants.Results:The RSCA scores within the high ASSQ scoring group,were inferior to those in the low scoring group.ASSQ scores were negatively correlated with RSCA scores for the full sample(Ps＜0.01);Social interaction scores on the ASSQ were negatively correlated with the five-factor RSCA scores(β=-0.23,-0.27,-0.11,-0.23,-0.37,Ps＜0.05).Conclusion:There was a negative association between autism spectrum disorder-like behaviors and resilience in adolescents,with more severe social interaction symptoms being associated with poorer resilience.
