ObjectiveTo investigate the potential mechanism of heat-sensitive moxibustion on chronic atrophic gastritis （CAG） through the phosphoinositide 3-kinase/protein kinase B （PI3K/Akt） signaling pathway. MethodsFifty-eight SD rats were randomly divided into blank group （n=14） and modeling group （n=44）. Rats in the blank group were fed routinely， while the rats in the modeling group received drinking water containing 1-methyl-3-nitro-1-nitrosoguanidine （MNNG） at a concentration of 140 μg/ml， combined with irregular fasting and feeding for 12 weeks to establish CAG model. After successful modeling， the rats were randomly divided into model group （n=10）， inhibitor group （n=10） and moxibustion group （n=20）. After 40 minutes of suspended moxibustion at "Zhongwan" （CV 12） daily， the rats in the moxibustion group were divided into heat-sensitive moxibustion group （n=10） and non-heat-sensitive moxibustion group （n=9） according to the change of tail temperature during moxibustion. The inhibitor group was bound for 40 minutes daily， and then administered with PI3K/Akt signaling pathway inhibitor， rapamycin solution， by gavage at a dose of 1 mg/kg. The model group received intragastric administration of 1 ml/kg normal saline after 40 minutes of restraint stress each day. All interventions were administered once daily for 28 consecutive days， while the blank group received no intervention. After the intervention finished， the body weight of rats in each group was compared. HE staining was used to observe the histopathological changes of gastric mucosa. The apoptosis-positive rate of gastric mucosal cells was detected by TUNEL assay. Immunohistochemistry was performed to determine the protein levels of matric metalloproteinase-7 （MMP7）， vascular endothelial growth factor A （VEGFA） and epidermal growth factor receptor （EGFR） in gastric mucosa. The mRNA expression levels of PI3K， Akt and mammalian target of rapamycin （mTOR） in gastric mucosal tissues were detected by qPCR. The protein levels of phosphorylated Akt （p-Akt） and phosphorylated mTOR （p-mTOR） in rat gastric mucosal tissues were measured by Western Blotting. ResultsCompared to the blank group， rats in all other groups exhibited decreased body weight， significantly increased gastric mucosal cell apoptosis-positive rates， elevated protein levels of MMP7， VEGFA and EGFR in gastric mucosa， increased mRNA expression levels of PI3K， Akt and mTOR， and enhanced protein expression levels of p-Akt and p-mTOR （P＜0.05 or P＜0.01）. Histopathological examination revealed thinning of the gastric mucosa， glandular disorganization and atrophy， accompanied by intestinal metaplasia.Compared to the model group， the heat-sensitive moxibustion group， the non-heat-sensitive moxibustion group and the inhibitor group all showed significant improvements in the above-mentioned indicators （P＜0.05 or P＜0.01）. Compared to the heat-sensitive moxibustion group， the non-heat-sensitive moxibustion group and the inhibitor group exhibited increased positive rates of gastric mucosal cell apoptosis； the non-heat-sensitive moxibustion group showed increased protein levels of MMP7， VEGFA and EGFR， as well as mRNA expression levels of PI3K， Akt and mTOR， and protein expressions of p-Akt and p-mTOR； the inhibitor group exhibited elevated protein expression level of EGFR （P＜0.05 or P＜0.01）. Histopathological examination showed that the gastric mucosal glands in the heat-sensitive moxibustion group were arranged more regularly， with an approximately normal structural appearance. ConclusionHeat-sensitive moxibustion can improve the body weight of CAG rats and repair gastric mucosal injury. Its therapeutic effects may be mediated by inhibiting excessive activation of gastric mucosal PI3K/Akt signaling pathway， thereby reducing gastric mucosal cell apoptosis.

Objective To compare the safety and efficacy of balloon-occluded retrograde transvenous obliteration(BRTO),endoscopic ultrasound(EUS)-guided coil embolization combined with endoscopic injection of cyanoacrylate,and titanium clip-assisted endoscopic cyanoacrylate injection(CLIP-ECI)in the treatment of gastric varices based on a network meta-analysis.Methods A computerized retrieval of randomized controlled trials(RCT)and retrospective studies concerning the"balloon-occluded retrograde transvenous obliteration""EUS-guided coil embolization combined with endoscopic injection of cyanoacrylate"and"titanium clip-assisted endoscopic cyanoacrylate injection"from the databases of PubMed,Web of Science,Cochrane Library,Embase,CNKI,Wanfang Medical Network,and CBM was conducted.The retrieval time period was from the establishment of the database to July 1,2024.Studies were selected based on inclusion and exclusion criteria,and data were processed using a random-effects model with STATA14.0 software for network meta-analysis.Results A total of 22 articles,including 7 RCTs and 15 retrospective studies,were included in this analysis,with a total sample size of 2 122 patients.The network meta-analysis showed that in terms of rebleeding prevention,the BRTO group(SUCRA 93.5)had the lowest rebleeding rate,followed by the EUS group(SUCRA 72.0);in terms of mortality,the CLIP-ECI group(SUCRA 82.1)had the lowest overall mortality,followed by the BRTO group(SUCRA 75.5);in terms of ectopic embolism rate,the BRTO group(SUCRA 68.7)had the smallest likelihood of ectopic embolism,while the ECI group(SUCRA 23.8)had the highest likelihood;in terms of gastric variceal eradication,the BRTO group(SUCRA 95.4)had the highest variceal eradication rate,followed by the EUS group(SUCRA 60.7).Conclusion Compared with endoscopic therapy,BRTOcan reduce the rebleeding rate of gastric varices and increase the eradication rate,with lower rates of ectopic embolization and mortality.Therefore,BRTO is an effective and safe means for the treatment of gastric varices.

Objective To explore the influencing factors of cognitive impairment in non-dialysis patients with chronic kidney disease(CKD).Methods A total of 60 hospitalized non-dialysis patients with CKD in the Department of Nephrology of Northern Jiangsu People's Hospital Affiliated to Yangzhou University from September 2022 to September 2023 were enrolled as research objects.According to the estimated glomerular filtration rate(eGFR),they were divided into stage 1 to 2 of CKD group[eGFR ≥60 mL/(min·1.73 m2)]with 23 cases,the stage 3 of CKD group[eGFR 30～＜60 mL/(min·1.73 m2)]with 20 cases,and stage 4 to 5 of CKD group[eGFR＜30 mL/(min·1.73 m2)]with 17 cases.The Montreal Cognitive Assessment Scale(MoCA)was used to evaluate the cognitive function of the patients.Basic data and common clinical laboratory in-dicators on hospital admission were collected to analyze the differences in cognitive function levels under different renal function statuses and to explore the influencing factors of cognitive impairment.Results The incidence rates of cognitive impairment in the stage 1 to 2 of CKD group,stage 3 of CKD group,and stage 4 to 5 of CKD group were 47.8％,85.0％,and 94.1％respectively,the median MoCA scored 26,24 and 20 respectively,with statistically significant between-group differ-ences(P＜0.05).Cognitive function was significantly negatively correlated with age(r=-0.634,P＜0.001),blood urea nitrogen(BUN)(r=-0.574,P＜0.001),serum creatinine(Cr)(r=-0.417,P＜0.001),cystatin C(Cys-C)(r=-0.327,P=0.011),serum β2-microglobulin(β2-MG)(r=-0.259,P=0.046),and N-terminal pro-brain natriuretic peptide(NT-proBNP)(r=-0.474,P＜0.001),and was significantly positively correlated with hemoglobin(HB)(r=0.401,P=0.001)and eGFR(r=0.485,P＜0.001).Multivariate Logistic regression analysis showed that age(P=0.006)and NT-proBNP(P=0.041)were influencing factors of cognitive im-pairment in non-dialysis patients with CKD.Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC),sensitivity,and specificity of age for prediction were 0.860,0.864 and 0.812 respectively,the AUC,sensitivity,and specificity of NT-proBNP for pre-diction were 0.808,0.795 and 0.875 respectively,and the combined prediction of age and NT-proBNP had an AUC,sensitivity,and specificity of 0.893,0.955,and 0.750,respectively.Conclusion As renal function deteriorates,the incidence rate and severity of cognitive impairment in non-dialysis patients with CKD tend to increase.Advanced age,renal function deterioration,high NT-proBNP level,and anemia are associated with the occurrence of cognitive impairment in non-di-alysis patients with CKD,among which age and NT-proBNP are influencing factors for cognitive im-pairment.

Objective To explore the regulatory mechanism of NFE2L2/KEAP1 in alveolar bone repair induced by periodontitis.Methods A rat periodontitis model was established and divided into four groups:Control group(n=6);Periodontitis model group(n=6);Periodontitis+lentivirus empty vector group(n=6);Periodontitis+NFE2L2 overexpression plasmid group(n=6).Histopathological changes in each group were observed using HE staining.TRAP staining was used to detect osteoclast positivity,while ELISA was employed to measure inflammatory cytokine levels in tissues.Immunofluorescence and qPCR were used to detect NFE2L2 expression,and western blot was used to assess the expression of osteogenic proteins ALPL2,RUNX2,and COL1.Primary periodontal ligament cells(hPDLCs)were cultured,and cells were transfected to overexpress NFE2L2 and KEAP1.The cells were divided into six groups:Normal group;Model group;pcDNA-NC group;pcDNA-NFE2L2 group;pc-NFE2L2+pcDNA-NC group;pc-NFE2L2+pcDNA-KEAP1 group.A cellular model was established,and the morphology of primary hPDLCs was observed under a microscope.Cell proliferation was assessed using CCK-8.Osteogenic mineralization was observed using alizarin red staining,and western blot was used to detect osteogenic proteins and autophagy markers.Cell migration was observed using a scratch assay.Results(1)After model induction,redness,swelling of the gums,extensive inflammatory infiltration,and alveolar bone resorption were observed,confirming successful model establishment.Partial tissue recovery occurred after NFE2L2 overexpression via lentivirus.(2)After model induction,osteoclast positivity increased,confirming successful model establishment.Overexpression of NFE2L2 reduced osteoclast positivity(P<0.001).(3)After model induction,levels of IL-1β,IL-10,and TNF-α were significantly higher than in the normal group(P<0.05),confirming successful model establishment.Transfection with NFE2L2 lentivirus reduced inflammatory cytokine levels(P<0.0001).After model induction,osteogenic protein expression decreased compared to the normal group,but overexpression of NFE2L2 increased osteogenic protein expression(P<0.05).(5)LPS treatment significantly reduced cell viability,while NFE2L2 overexpression enhanced it(P<0.0001).(6)LPS treatment reduced calcified nodules,while NFE2L2 overexpression increased them.Addition of pcDNA-KEAP1 reduced mineralized nodules.(7)LPS treatment decreased osteogenic protein expression,while NFE2L2 overexpression increased it.However,addition of pcDNA-KEAP1 reduced osteogenic protein expression(P<0.05).(8)LPS treatment reduced cell migration,whereas NFE2L2 overexpression enhanced it(P<0.0001).(9)Expression of autophagy markers decreased after LPS treatment,but increased after transfection with NFE2L2 plasmid.However,addition of pcDNA-KEAP1 reduced the expression of autophagy markers(P<0.05).Conclusion This study identified the regulatory role of NFE2L2/KEAP1 in periodontitis,providing a scientific basis for the treatment of periodontitis.

Objective: To investigate the association between the physical fitness index (PFI) and symptoms of depressive, anxiety and stress symptoms among college students, providing a reference for mental health interventions. Methods: From June to September 2025, combined convenience and cluster random sampling approach was used to administer questionnaire surveys and perform physical fitness tests on 2 712 college students from Zhejiang Chinese Medical University. The Depression Anxiety Stress Scales-21 Items (DASS-21) was used to assess mental health status. Chi square test and multivariate Logistic regression analysis were used to determine the associations between the PFI and the PFI component indicators with depressive, anxiety and stress symptoms. Results: The prevalence of depressive, anxiety and stress among college students were 24.26%, 33.22% and 13.68%, respectively. Statistically significant differences in the prevalence of these symptoms were detected across groups differing in sleep quality, physical activity, weekly breakfast frequency, and history of low back or neck pain ( χ 2=9.33-151.83, all P <0.05). After adjusting for confounding factors, Logistic regression revealed that the moderate and high PFI groups had significantly reduced risks of depressive and anxiety compared to the low PFI group ( OR =0.73, 0.63; 0.61, 0.72, all P <0.05). Poor speed (50 m run) and lower body strength (standing long jump) emerged as common risk factors affecting anxiety and depressive symptoms in both male and female college students (all P <0.05). Increased muscle strength (sit up for 1 min) in female students reduced the risk of depressive ( OR =0.81), anxiety ( OR =0.85), and stress symptoms ( OR =0.79) (all P <0.05). Enhanced lung capacity in male students decreased the risk of depressive ( OR =0.84) and anxiety symptoms ( OR =0.85) (both P <0.05). Conclusions The PFI is negatively correlated with depressive and anxiety symptoms among college students with notable gender differences. Insufficient speed and lower body explosive power represent common risk factors for mental health among male and female college students.

BACKGROUND: As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034. METHODS: The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC). RESULTS: Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively. CONCLUSIONS The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

This review summarizes recent advances in neoadjuvant immunotherapy for advanced gastric cancer.Through literature search in PubMed,Web of Science,and CNKI databases from 2020 to 2023,we systematically analyzed the mechanisms,clinical applications,and bio-marker research.Programmed death-1(PD-1)inhibitors combined with chemotherapy significantly improve patient outcomes,while mi-crosatellite instability(MSI),programmed death-ligand 1(PD-L1)expression,and tumor mutational burden(TMB)have been identified as important predictive biomarkers.Multi-omics analysis shows great potential in identifying optimal responders,with pyroptosis-related gene scoring system(PRS)positively correlating with anti-tumor immune infiltration.Metabolic reprogramming and epigenetic regulation in the tumor microenvironment play key roles in immune evasion,while emerging targets such as Claudin 18.2 and combination targeting strategies further enhance therapeutic efficacy.Despite significant progress,precise patient selection and overcoming resistance mechan-isms remain major challenges.Future research should focus on biomarker validation,personalized treatment strategy development,tumor microenvironment dynamic analysis,and novel combination therapy exploration to improve clinical outcomes.

Objective To investigate the significance of CD4 and CD8 T lymphocyte ATP release assays for the assessment of cellular immune function in patients with digestive tract tumors.Methods 51 digestive tract tumor patients from the Department of Oncology and Department of Radiotherapy of the General Hospital of Southern Theater Command of PLA during 2023～2024 as a study group,and 51 healthy medical checkups were collected from the Physical Examination Center of that Hospital during 2018～2020 as a control group,and the counts of leukocytes,lymphocytes,CD4 T lymphocyte,and CD8 T lymphocyte were conducted to detect the release of ATP from CD4,CD8 T lymphocyte before and after the stimulation of PHA Levels of ATP release from CD4 and CD8 T lymphocytes before and after PHA stimulation.Results Lymphocyte counts[1.45(1.12,1.75)×109/L]and CD8 T lymphocyte counts[357.00(232.13,451.35)个/μl]in the research group was lower than in the control group[2.04(1.24,2.27)×109/L,454.36(368.00,566.10)个/μl],and the differences were statistically significant(Z=-4.719,-3.209,all P<0.05).After PHA stimulation,the ATP release level of CD4 T lymphocytes in the research group was lower than that in the control group(Z=-2.181,P＜0.05),and the level of ATP release level of CD8 T lymphocytes in the research group before and after PHA stimulation were lower than those in the control group(Z=-3.314,-3.462,all P<0.05).There was no correlation between CD4 T lymphocyte ATP release values and CD4 T lymphocyte counts in the research group(r=0.617,P=0.093),and there was a positive correlation between CD4 T lymphocyte ATP release values and CD4 T lymphocyte counts in the control group(r=0.276,P=0.049).There was no significant correlation between the ATP release values of CD8 T lymphocytes and lymphatic counts in the research group(r=0.033,P=0.816),and a positive correlation between the ATP release values of CD8 T lymphocytes and lymphatic counts in the control group(r=0.278,P=0.048).Conclusion The CD4 and CD8 T lymphocyte ATP release assay can be used as a method to evaluate the dynamic function of cellular immunity,and in combination with static cell counting can provide a more comprehensive assessment of cellular immunity in patients with gastrointestinal tumors.
