Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

Objective To systematically evaluate the effect of threshold inspiratory muscle training on pulmonary rehabilitation in postoperative lung cancer patients,with a focus on exploring the difference in efficacy under different interven-tion modes.Methods Randomized controlled trials on the effect of threshold inspiratory muscle training on pulmonary rehabilitation in postoperative lung cancer patients were retrieved from PubMed,Cochrane Library,Embase,Web of Science,CNKI,Wanfang data,VIP and China Biomedical Literature Database.Meanwhile,gray literature from ProQuest and clinicaltrials.gov was searched as supplements.The retrieval period was from the establishment of each data-base to May 9,2025.Cochrane 5.1.0 was used to evaluate the quality of literature,and a meta-analysis was per-formed using RevMan 5.4.Results Twelve studies involving 701 patients were included,all of which were of moderate to high quality.Threshold inspiratory muscle training could reduce the pulmonary complications of postoperative lung cancer patients(OR=0.45,95%CI 0.29 to 0.68,P<0.001),shorten the hospital stay(MD=-1.85,95%CI-3.29 to-0.42,P=0.010),improve the inspiratory muscle strength(MD=5.84,95%CI 0.96 to 10.71,P=0.020),enhance their ex-ercise endurance(SMD=0.40,95%CI 0.10 to 0.71,P=0.010),and did not increase the risk of pulmonary air leakage(OR=0.88,95%CI 0.47 to 1.63,P=0.680).Subgroup analysis revealed that shortening of hospital stay(MD=-2.98,95%CI-5.87 to-0.09,P=0.040)and the improvement in exercise endurance(SMD=0.57,95%CI 0.14 to 1.00,P=0.009)were significant only when threshold inspiratory muscle training was combined with aerobic exercise.However,standalone threshold inspiratory muscle training showed no statistical signifi-cance in these two outcomes.Conclusion Threshold inspiratory muscle training can effectively reduce postoperative pulmonary complications and im-prove inspiratory muscle strength in postoperative lung cancer patients with good safety.Threshold inspiratory muscle training could shorten hospital stay and improve exercise endurance only when combining with aerobic exercise.

Objective To integrate the Timing It Right(TIR)framework with Phase Ⅰ Cardiac Rehabilitation(CR)strategies to develop a staged,individualized rehabilitation protocol for patients after Transcatheter Aortic Valve Replacement(TAVR)and verify its clinical effectiveness.Methods A quasi-experimental study design was employed.A total of 128 TAVR patients admitted to Kunming Yan'an Hospital between January 2023 and December 2024 were selected as participants and randomly assigned via a random number table to either an intervention group(n=64)or a control group(n=64).The control group received routine care,while the intervention group received TIR theory-based Phase Ⅰ cardiac rehabilitation nursing care in addition to routine care.This intervention was implemented across three stages:diagnostic,perioperative,and discharge preparation period.Comparisons were made between the two groups regarding Left Ventricular Ejection Fraction(LVEF),the 6-Minute Walk Test(6MWT)distance,the incidence of Major Adverse Cardiac and Cerebrovascular Events(MACCE),scores across all domains of the China Questionnaire of Quality of Life in patients with Cardiovascular Diseases(CQQC),and patient satisfaction before and after the intervention.Results After the intervention,the intervention group demonstrated significantly higher LVEF and 6MWT results at both discharge and 3 months postoperatively compared to the control group(P<0.05).The incidence of MACCE was significantly lower in the intervention group(4.84％)than in the control group(13.33％).Scores across all CQQC domains and patient satisfaction were significantly superior in the intervention group than in the control group(P<0.05).Furthermore,The length of ICU stay and total hospitalization duration were significantly shorter in the intervention group compared to the control group(P<0.05).Conclusion Phase I cardiac rehabilitation nursing care based on the Timing It Right theory effectively improves cardiac function and exercise tolerance in TAVR patients,reduces the risk of MACCE.

Objective To analyze the predictive value of serum levels of procalcitonin(PCT)and cytokines on the prognosis of patients with COVID-19 at admission.Methods From November 2022 to February 2023,patients diagnosed with COVID-19 who were admitted to Beijing Chest Hospital were enrolled.Chemiluminescence was used to detect serum PCT levels,and flow microsphere array was used to detect serum cytokines IL-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17A,IL-17F,IL-22,TNF-α,TNF-β,IFN-γ level.ICU admission,mechanical ventilation and in-hospital death were defined as poor prognosis.After excluding patients with bacterial infection,the relationship between serum PCT and cytokine levels at admission and the prognosis of COVID-19 patients was analyzed.After excluding patients with bacterial infection,the relationship between serum PCT and cytokine levels at admission and the prognosis of COVID-19 patients was analyzed.Results A total of 176 patients with complete data were included,including 134 in the PCT-normal group and 42 in the PCT-elevated group,with a median age of 71.50 years and 71.59%males.Patients in the PCT elevated-group had significantly higher rates of ICU admission(38.41%vs.13.11%,P<0.05),mechanical ventilation(76.92%vs.24.59%,P<0.001)and in-hospital mortality(38.46%vs.6.56%,P<0.001)were significantly higher than those in the PCT-normal group.Serum levels of cytokines IL-6(7.40 pg/mL vs.4.78 pg/mL,P = 0.033 4)and IL-8(10.97 pg/mL vs.5.92 pg/mL,P<0.001)were significantly higher in patients with poor prognosis than in those with good prognosis.The area under the curve for PCT,IL-6,and IL-8 to predict poor prognosis in COVID-19 patients was 0.687,0.660,and 0.746,respectively;sensitivity was 52.78%,55.17%,and 72.41%,respectively;and specificity was 81.58%,74.19%,and 74.19%,respectively,as calculated from the ROC curve.When PCT,IL-6 and IL-8 jointly predict the prognosis of COVID-19 patients,the area under the curve is 0.764,the sensitivity is 70.00%,and the specificity is 80.00%.Conclusion Serum PCT and cytokines IL-6 and IL-8 could be used as predictive markers for poor prognosis in patients with COVID-19.

The functional role of glutamatergic (vGluT2) neurons in the pedunculopontine nucleus (PPN) in modulating motor activity remains controversial. Here, we demonstrated that the activity of vGluT2 neurons in the rostral PPN is correlated with locomotion and ipsilateral head-turning. Beyond these motor functions, we found that these rostral PPN-vGluT2 neurons remarkably respond to salient stimuli. Furthermore, we systematically traced the upstream and downstream projections of these neurons and identified two downstream projections from these neurons to the caudal pontine reticular nucleus/anterior gigantocellular reticular nucleus (PnC/GiA) and the zona incerta (ZI). Our findings indicate that the projections to the PnC/GiA inhibit movement, consistent with 'pause-and-play' behavior, whereas those to the ZI promote locomotion, and others respond to a new 'pause-switch-play' pattern. Collectively, these findings elucidate the multifaceted influence of the PPN on motor functions and provide a robust theoretical framework for understanding its physiological and potential therapeutic implications.

Objectives:To report a novel mutation site in the pathogenic gene TTR of transthyretin cardiac amyloidosis(ATTR-CA),and to identify family members at risk,and provide suitable clinical diagnosis and treatment. Methods:A retrospective analysis was conducted on the clinical data of the proband with ATTR-CA who visited the Department of Cardiology,the First Affiliated Hospital of Zhengzhou University in March 2021.The proband underwent whole exome sequencing using high-throughput methods to detect mutation genes.Sanger sequencing was used to test candidate pathogenic loci in suspected family members,and relevant literature was reviewed. Results:Among 51 individuals spanning 5 generations in the pedigree,10 family members(including the proband)carried the heterozygous TTR gene c.163A>G mutation,resulting in the amino acid residue at position 55 changing from lysine(Lys)to glutamic acid(Glu).This mutation follows an autosomal dominant inheritance pattern,with early onset in adulthood,rapid progression,and presenting as a mixed-type ATTR-CA.Five mutation carriers had different clinical manifestations,while the remaining 5 mutation carriers,who are at younger age,have not yet shown symptoms.Within the pedigree,7 individuals died(the proband's uncle[Ⅱ-1]who died from stroke at 65 years old,the rest 6 family members died from heart disease before the age of 50). Conclusions:According to the American College of Medical Genetics and Genomics guidelines,TTR gene Lys55Glu mutation is classified as likely pathogenic,this mutation site has not been reported in the literature before.Present study adds clinical evidence that might broaden the spectrum of TTR mutations.

Objective:To explore the mechanism of exacerbating chronic graft versus host disease (GVHD) in mice with inflammatory status and enhancing immune injury in mice with PD-1.Method:Bone marrow and spleen cells of DBA/2 mice were injected into BALB/C mice pretreated with chemotherapy regimen (Flu+Bu) for constructing a chronic GVHD model. The animals were assigned into two groups of zymosan (100M SPL+10M BM+Zymosan) and control (100M SPL+10M BM+ PBS). After transplantation, two groups of mice were observed for weight changes, survival status and chronic GVHD manifestations. Target organ tissues were harvested for pathological scoring. Flow cytometry was employed for detecting cell subpopulations and surface co-stimulatory molecules in target organs. PD-1 monoclonal antibody was injected into inflammatory murine model. Mice were observed and target organ cells were harvested for subsets and co-stimulatory factors.Result:In in vivo experiments, zymosan group showed more significant changes of chronic GVHD with higher mortality rate, faster weight loss and more severe symptoms of GVHD. At Week 2 post-transplantation, hematoxylin-eosin stain of target organ tissue was performed for pathology examination. Zymosan group showed more lymphocyte infiltration, more severe inflammation and more significant tissue injury with higher GVHD pathological score. The proportion of M2 in liver/lung of zymosan group was significantly lower than that of control group ( P<0.05) and no significant difference existed in the proportion of M1. In in vivo experiments, M1 ratio of splenic cell spiked markedly in zymosan group as compared to control group while M2 ratio declined greatly. The secretions of IL-4 and IL-10 dropped significantly while co-stimulatory molecules CD80 and CD86 rose obviously. Conclusion:The worsening graft-versus-host disease in inflammatory mice with anti-PD1 treatment is associated with a decline of Treg proportion.

Objective:To explore the effect of Xingnao Kaiqiao acupuncture treatment on brain network reorganization for the patients with stroke recovery, and therefore understand the neural mechanism underlying Xingnao Kaiqiao acupuncture treatment.Methods:Prospective case series study. Thirteen acute ischemia stroke patients were recruited from the Department of Neurology, Shanghai Minhang Hospital of Integrated Traditional Chinese and Western Medicine from Aug 2018 to Oct 2019. They were treated with Xingnao Kaiqiao acupuncture once a day for 10 consecutive days in addition to routine treatments, and received clinical assessments before treatment and 14 days after treatment onset. EEG signals were recorded during the first acupuncture treatment, from before inserting the needles (the baseline), during needle retention, to after removal of the needles. The brain network was constructed using phase locking index, and its clustering coefficient (CC), characteristic path length (PL) and small-worldness (S) were analyzed using one-way repeated ANOVA.Results:Compared with the baseline, the CC of delta-band network (sparsity=0.10: t=3.306, P=0.006; 0.12: t=2.909, P=0.013; 0.14: t=2.331, P=0.038) and the PL of delta-band (sparsity=0.12: t=3.236, P=0.007; 0.14: t=2.754, P=0.017, 0.18: t=2.878, P=0.014) and alpha-band (sparsity=0.10: t=2.432, P=0.032) networks were significantly decreased during the needle retention stage. Clinical assessments demonstrated a significant treatment efficacy of Xingnao Kaiqiao acupuncture, and its efficacy which was indicated by improved NIHSS score, was significantly correlated with the CC changes in the delta band network from baseline to needle retention. The correlation was strongest when the network sparsity was 0.12 ( r=0.78, P=0.002). Conclusion:Xingnao Kaiqiao acupuncture can regulate the brain network of stroke patients in real time, and this immediate regulation maybe associated with its treatment effect.
