ObjectiveBased on the theory of "spleen governing transportation and transformation"， this study investigates the efficacy of Atractylodis Macrocephalae Rhizoma processed with Aurantii Fructus Immaturus juice（AMR-AFI） in improving slow-transit constipation（STC）， as well as the synergistic regulatory mechanism involving the microbiota-metabolism axis， thereby elucidating the scientific basis of its processing theory. MethodsAnimals were randomly divided into the control group， model group， positive drug（mosapride） group（3 mg·kg^-1）， and low-， medium-， and high-dose groups of AMR-AFI（3.9， 7.8， 15.6 g·kg^-1）. Except for the control group， the remaining five groups were induced with STC using loperamide hydrochloride. Following modeling， interventions were administered. All groups received continuous administration for 15 d， during which fecal samples， colon tissue， and serum were collected. Constipation improvement was assessed by measuring fecal moisture content and small intestinal propulsion rate， histological morphology of colonic tissue was observed via hematoxylin-eosin（HE） staining， and the levels of interleukin（IL）-6， tumor necrosis factor（TNF）-α， and IL-2 in serum were detected using enzyme-linked immunosorbent assay（ELISA）. Furthermore， the microbial community structure in mouse feces was analyzed by 16S rRNA sequencing， while transcriptomic sequencing was employed to screen differentially expressed genes in colonic tissue， followed by gene ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analyses. Finally， Spearman correlation analysis was conducted to explore the association between differential microbiota and differential genes. ResultsCompared with the control group， the intestinal propulsion rate and fecal moisture content in the model group were significantly decreased（P<0.01）， while serum levels of IL-6， TNF-α， and IL-2 were significantly elevated（P<0.01）. HE staining showed damage and shedding of colonic mucosal epithelial cells， along with a reduction in goblet cells in the model group. In comparison with the model group， all treatment groups improved the pathological state of the colonic mucosa to varying degrees and reduced serum levels of IL-6， TNF-α， and IL-2（P<0.01）. Among these， the high-dose group of AMR-AFI significantly increased the intestinal propulsion rate and fecal moisture content of rats（P<0.05， P<0.01）. Further transcriptomic analysis revealed that a total of 104 differentially expressed genes were identified from comparisons between the model group and the control group， as well as between the model group and the high-dose group of AMR-AFI. These genes were mainly enriched in pathways closely related to STC pathogenesis， such as arachidonic acid metabolism and aldosterone-regulated sodium reabsorption. 16S rRNA sequencing results indicated that AMR-AFI reversed the structural imbalance of the gut microbiota in model mice， increased species richness， downregulated the relative abundance of pro-inflammatory bacteria such as Parasutterella， and enriched beneficial and butyrate-producing bacteria， including Lachnospiraceae_NK4A136_group， Ruminococcaceae， and Lachnospiraceae. Spearman correlation analysis further showed that the beneficial bacteria enriched in the AMR-AFI group were negatively correlated with genes involved in the arachidonic acid metabolic pathway and positively correlated with genes in the aldosterone-regulated sodium reabsorption pathway. In contrast， pro-inflammatory bacteria in the model group exhibited the opposite correlation trends. ConclusionAMR-AFI can effectively exert synergistic therapeutic effects on STC by regulating intestinal microbiota， arachidonic acid-mediated inflammatory metabolism， and aldosterone-regulated water-salt balance pathways.

Objective To evaluate the long-term survival of patients with T1a-bN0M0 non-small cell lung cancer (NSCLC) after sublobar resection. Methods Patients with T1a-bN0M0 NSCLC who underwent sublobar resection from 2004 to 2015 were selected from the Surveillance, Epidemiology, and End Results (SEER) database, and divided into a segmentectomy group and a wedge resection group according to the resection method. After propensity-score matching at a ratio of 1:1, the overall survival (OS) and disease-specific survival (DSS) of patients were analyzed using Cox regression model, log-rank test, and restricted mean survival time (RMST). Results A total of 3262 patients were included in the study, including 1321 males and 1941 females, with a median age of 69.0 years. Among them, 2419 patients were in the wedge resection group and 843 patients were in the segmentectomy group. After matching, 843 pairs of patients were obtained. The results showed that the 10-year DSS rate (68.0% vs. 60.6%, P=0.011) and 10-year OS rate (40.8% vs. 37.0%, P=0.049) of the segmentectomy group were better than those of the wedge resection group, while there was no statistical difference in the 5-year DSS rate (82.9% vs. 79.5%, P=0.112) or 5-year OS rate (68.9% vs. 64.9%, P=0.096). Multivariate Cox regression analysis revealed that male gender [HR=1.54, 95%CI (1.28-1.86), P<0.001] and age [HR=1.02, 95%CI (1.01-1.03), P<0.001] were independent risk factors for DSS, while increased number of regional nodes dissected (RND) [HR=0.98, 95%CI (0.96-1.00), P=0.018] and segmentectomy [HR=0.82, 95%CI (0.68-0.98), P=0.030] served as protective factors. For OS, male gender [HR=1.54, 95%CI (1.35-1.75), P<0.001], age [HR=1.04, 95%CI (1.03-1.04), P<0.001], and histological subtypes of squamous cell carcinoma [HR=1.62, 95%CI (1.41-1.86), P<0.001] or large cell carcinoma [HR=1.64, 95%CI (1.07-2.52), P=0.023] were identified as independent risk factors, whereas increased RND was a protective factor [HR=0.98, 95%CI (0.97-0.99), P=0.002]. Surgical approach was not an independent prognostic factor for OS. Subgroup analysis showed that segmentectomy had a better 10-year OS-RMST in patients with adenocarcinoma (P=0.045), right lower lobe tumor (P=0.014), and tumor diameter ≤1.6 cm (P=0.006). Conclusion Increasing lymph node dissection during sublobar resection may improve prognosis. Compared with wedge resection, segmentectomy may improve the long-term DSS rate of patients with T1a-bN0M0 NSCLC.

Cardiac arrest (CA) is a critical condition in the field of cardiovascular medicine. Despite successful resuscitation, patients continue to have a high mortality rate, largely due to post CA syndrome (PCAS). However, the injury and pathophysiological mechanisms underlying PCAS remain unclear. Experimental animal models are valuable tools for exploring the etiology, pathogenesis, and potential interventions for CA and PCAS. Current CA animal models include electrical induction of ventricular fibrillation (VF), myocardial infarction, high potassium, asphyxia, and hemorrhagic shock. Although these models do not fully replicate the complexity of clinical CA, the mechanistic insights they provide remain highly relevant, including post-CA brain injury (PCABI), post-CA myocardial dysfunction (PAMD), systemic ischaemia/reperfusion injury (IRI), and the persistent precipitating pathology. Summarizing the methods of establishing CA models, the challenges encountered in the modeling process, and the mechanisms of PCAS can provide a foundation for developing standardized CA modeling protocols.

OBJECTIVES: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. METHODS: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling. The changes in body weight, disease activity index (DAI), colon length, spleen weight, and colon histological scores of the mice were examined, and the percentages of Th17 and IFN-γ⁺ CD8⁺ T cells in the mesenteric lymph nodes and spleen were analyzed using flow cytometry. The expressions of tight junction proteins (Occludin and ZO-1), proteins associated with inflammasome activation (caspase-1 and p20), IL-1β and TNF-α in the colon tissues were detected using Western blotting or ELISA. In the cell experiment, mouse bone marrow-derived macrophages (BMDMs) primed with lipopolysaccharide (LPS) were treated with DMQ, followed by stmulation with nigericin to activate the classical NLRP3 inflammasome pathway. In cultured human peripheral blood mononuclear cells (PBMCs) treated with either LPS alone or LPS plus nigericin, the effects of DMQ on inflammasome activation, pyroptosis, and cytokine release were evaluated via Western blotting, ELISA, and flow cytometry. RESULTS: In DSS-treated mice, DMQ treatment significantly alleviated DSS-induced body weight loss, colon shortening, spleen enlargement, and colon inflammation. The DMQ-treated mice showed significantly reduced percentages of Th17 cells and IFN-γ⁺ CD8⁺ T cells in the mesenteric lymph nodes and spleen, with increased occludin and ZO-1 expressions and decreased caspase-1 expression in the colon tissue. DMQ obviously inhibited classical NLRP3 inflammasome activation in mouse BMDMs and both the classical and alternative pathways of NLRP3 activation in human PBMCs, causing also suppression of caspase-1-dependent pyroptosis. CONCLUSIONS DMQ ameliorates DSS-induced UC in mice by inhibiting NLRP3 inflammasome activation.

OBJECTIVE: To explore the clinical features of the sepsis in immunocompromised hosts and establish an early warning equation. METHODS: A retrospective study was conducted on sepsis patients admitted to the intensive care unit (ICU) of Binzhou Medical University Hospital from October 2011 to October 2022. General information, infection site, etiology results and drug susceptibility, clinical symptoms, inflammatory indicators, acute physiology and chronic health status evaluation II (APACHE II), sequential organ failure assessment (SOFA), incidence of immune paralysis, and outcome during hospitalization were collected. Based on whether they met the diagnostic criteria for immunocompromised hosts, patients were divided into immunocompromised group and immune normal group. The clinical information of the two groups were compared. Multivariate Logistic regression was used to analyze the risk factors of patients with immunocompromised sepsis and the regression equation model was initially established. Omnibus test and Hosmer-Lemeshow test were used to evaluate the model. RESULTS: A total of 169 patients with sepsis were included, including 61 in the immunocompromised group and 108 in the normal immune group. The top 3 infection sites in the immunocompromised group were bloodstream infection, pulmonary infection and abdominal infection. The top 3 infection sites in the normal immune group were pulmonary infection, bloodstream infection and abdominal infection. The infection rate of Gram-negative bacteria in the immunocompromised group was significantly lower than that in the normal group [49.2% (30/61) vs. 64.8% (70/108), P < 0.05]. The infection rate of Gram-positive bacteria [27.9% (17/61) vs. 13.9% (15/108)] and multidrug-resistant bacteria [54.1% (33/61) vs. 29.6% (32/108)] were significantly higher than those in normal immune group (both P < 0.05). In terms of clinical symptoms, the proportion of fever in the immunocompromised group was significantly lower than that in the immune normal group [49.2% (30/61) vs. 66.7% (72/108), P < 0.05]. Neutrophil count (NEU) and neutrophil percentage (NEU%) in the immunocompromised group were significantly lower than those in the normal immune group. Lymphocyte percentage (LYM%), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), APACHE II score, combined shock rate, incidence of immune paralysis, and mortality during hospitalization in the immunocompromised group were significantly higher than those in the normal immune group. Logistic regression analysis showed that NLR, CRP and PCT were risk factors for patients with immunocompromised sepsis (all P < 0.05). The above indicators were used as covariables to construct a Logistic regression equation, that was, Logit (P) = 0.025X₁+0.010X₂+0.013X₃-2.945, where X₁, X₂ and X₃ represent NLR, CRP and PCT respectively. Omnibus test and Hosmer-Lemeshow test show that the model fits well and has certain early warning value. CONCLUSIONS Patients with immunocompromised sepsis have more intense inflammatory response, with Gram-negative bacteria being the predominant pathogen, and a higher incidence of Gram-positive bacterial infections and multi-drug resistant infections. The severity of the disease, in-hospital mortality, the incidence of shock and the incidence of immune paralysis after sepsis were significantly higher. NLR, CRP and PCT were independent risk factors for sepsis in immunocompromised hosts. The regression equation constructed based on this may have early warning significance for patients with immunocompromised sepsis.

OBJECTIVE: To investigate the effectiveness of basal osteotomy of the first metatarsal combined with first metatarsophalangeal joint replacement for the treatment of hallux valgus combined with hallux rigidus. METHODS: A retrospective analysis was conducted on the medical records of 15 patients (16 feet) with hallux valgus combined with hallux rigidus who underwent first metatarsal basal osteotomy combined with first metatarsophalangeal joint replacement between May 2019 and December 2024. The patients included 1 male and 14 females, aged 60-80 years, with an average age of 68.5 years. According to the Mann classification of hallux valgus, 2 feet were moderate and 14 feet were severe. According to the Hallux Rigidus Coughlin grading, 12 feet were grade 3 and 4 feet were grade 4. The evaluation indicators included hallux valgus angle (HVA) and intermetatarsal angle (IMA) measured on weight-bearing X-ray film at preoperation and last follow-up; the American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were used to evaluate the improvement of walking function, metatarsophalangeal joint function, and pain relief in patients. RESULTS: All patients underwent surgery successfully without complications such as vascular or nerve injury during operation. One foot developed a superficial incisional infection postoperatively, which healed after dressing changes; the remaining 15 feet had primary incision healing. All patients were followed up 5-55 months, with an average of 17.5 months. All osteotomies achieved bony union, with a union time ranging from 8 to 13 weeks, averaging 11.8 weeks; no elevation of the first metatarsal was observed. At last follow-up, no complications such as prosthesis loosening, dislocation, fracture, toe shortening, bone dissolution, synovial reaction, or metatarsalgia was found. The appearance and function of the affected feet significantly improved, and the pain significantly relieved. At last follow-up, the HVA, IMA, AOFAS score, and VAS score showed significant differences when compared with preoperative values ( P<0.05). CONCLUSION Basal osteotomy of the first metatarsal combined with first metatarsophalangeal joint replacement for the treatment of hallux valgus with hallux rigidus can correct deformities through osteotomy, restore the normal flexion-extension axis of the metatarsophalangeal joint, relieve pain, and preserve a certain degree of mobility, achieving good short- and mid-term effectiveness.

OBJECTIVE: To investigate the effectiveness of endoscopic-assisted median nerve decompression with one-stage extensor indicis proprius (EIP) tendon transfer for reconstruction of thumb abduction in patients with severe carpal tunnel syndrome (CTS). METHODS: The clinical data of 12 patients with severe CTS who met the selection criteria between December 2019 and December 2024 were retrospectively analyzed. There were 2 males and 10 females with an average age of 55.4 years ranging from 35 to 67 years. The symptom duration of CTS was 12-120 months (mean, 48.7 months) and the thenar muscle atrophy duration was 6-48 months (mean, 13.4 months). The median nerve was released with the help of endoscope, and the EIP tendon was transferred to reconstruct the abduction function of the thumb. The operation time and complications were recorded. Two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, and pinch force of the thumb were measured and compared before operation and at last follow-up, and the effectiveness was evaluated by Kapandji score and Disabilities of the Arm, Shoulder and Hand (DASH) score. The satisfaction of the operation was evaluated at last follow-up. RESULTS: All surgeries were successfully completed with a mean operation time of 54 minutes (range, 45-68 minutes). All patients were followed up 6-50 months, with an average of 15.3 months. There was no complications such as wound infection, scar pain of wrist, or tendon rupture of transposition, and there were 3 cases of mild limitation of finger extension in the donor site of index finger. At last follow-up, two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, Kapandji score, and DASH score were significantly better than those before operation ( P<0.05), but there was no significant difference in thumb pinch force between pre- and post-operation ( P>0.05). The evaluation of surgical satisfaction showed that 7 cases were very satisfied and 5 cases were satisfied. CONCLUSION The combination of endoscopic-assisted median nerve decompression and one-stage EIP tendon transfer effectively improves hand function and quality of life in patients with severe CTS by restoring thumb abduction and alleviating neurological symptoms.

Objective: To understand the current status of tuberculosis prevention and control knowledge and perceived stress among college and middle school students with pulmonary tuberculosis (PTB) in Yantai City, and to analyze the related factors, so as to provide a basis for the school to carry out health education and psychological counseling. Methods: A matched case control study was conducted, with 100 PTB student patients in junior high school and above who were diagnosed at designated medical institutions from October 2020 to October 2024. Four healthy control students of the same gender, same dormitory, or same class were selected for each case. Therefore, 100 cases and 400 controls were investigated by questionnaire. The following information was collected: personal basic information; tuberculosis prevention and control awareness; and scores of the Chinese Perceived Stress Scale (CPSS). Conditional Logistic regression model and mixed linear models were used to compare the PTB prevention and control awareness rate, as well as the perceived stress between the case and control groups. Multiple linear regression analysis was used to analyze the factors that may affect the perceived stress of students with PTB. Results: The awareness rates of four tuberculosis knowledge items (symptoms of PTB, main causes of onset after infection, consequences of PTB patients not receiving standardized and complete treatment, the most important method to prevent PTB) were higher in the case group (40.00%, 72.00% , 38.00%, 49.00%) than the control group (21.50%, 57.50%, 22.25%, 31.25%) and the differences were statistically significant ( Wald χ 2=18.44, 8.78, 13.20, 16.89, all P <0.01). The tension score (10.49±4.20), loss of control score ( 11.21± 4.58), and total score (21.70±6.88) in the case group were higher than the control group (9.35±4.73, 9.75±5.60, 19.09±8.36) and the differences were statistically significant ( t =2.21, 2.42, 2.88, all P <0.05). The results of multiple linear regression analysis showed that age ≥ 18 years and family history of tuberculosis were the related factors affecting the overall perceived stress and tension of college and middle school students with PTB ( B total scores =4.50, 5.91; B tension score =2.39, 3.23, all P <0.05). Conclusions The tuberculosis prevention and control awareness rate, and the perceived stress of college and middle school students with PTB in Yantai are both higher than students without tuberculosis. Moreover, the perceived stress of students with PTB who are aged ≥18 years or have a family history of tuberculosis is even higher.

Objective:To identify and validate the key genes of ferroptosis in phospholipase A2 receptor (PLA2R) associated membranous nephropathy through bioinformatics analysis and in vitro experiments, and to explore the potential role of ferroptosis in PLA2R associated membranous nephropathy (PMN). Methods:The GSE115857 dataset obtained by retrieving the Gene Expression Omnibus (GEO) database and the ferroptosis-related genes obtained by retrieving the FerrDb database were intersected. The intersected genes were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The key ferroptosis genes associated with PMN were identified by intersecting genes selected using support vector machines-recursive feature elimination and least absolute shrinkage and selection operator regression. The results were validate by real-time PCR, cell counting kit-8, Western blotting and immunofluorescence in human renal podocyte line AB 8/13 from both the control group and model group.Results:A total of 25 genes related to ferroptosis of PMN were obtained, and GO and KEGG analysis showed that these genes were mainly involved in cell ferroptosis metabolism. The key ferroptosis genes of PMN obtained by machine learning method were activating transcription factor 3 ( ATF3) and coiled coil domain containing 6 ( CCDC6). The results of in vitro experiments showed that the human renal podocyte line AB 8/13 in the model group was significantly deformed and retracted compared with the control group. The surface area density of foot processes was significantly reduced, and the podocyte cytoskeleton was allosteric. The morphology of F-actin was disordered and the expression of synaptopodin was decreased. The cell proliferation activity was significantly decreased ( P<0.05). The expression of PLA2R protein was increased ( P<0.05), and the expression of GPX4 protein was decreased ( P<0.01). The protein and mRNA levels of ATF3 and CCDC6 were significantly up-regulated (all P<0.05). Conclusions:Ferroptosis may be one of the key mechanisms in the occurrence and development of PMN. In vitro experiments show that ATF3 and CCDC6 are the key genes in the ferroptosis of PMN podocytes, which provides new insights and ideas for the pathogenesis of PMN.
