BACKGROUND:In the skeleton,various endogenous or exogenous stimuli cause imbalance in bone metabolism,leading to changes in bone mass and bone strength,which in turn cause a series of bone-related diseases such as osteoarthritis and osteoporosis.In this process,Forkhead box transcription factor O1(FoxO1)plays an important role,and FoxO1 can regulate bone metabolism by regulating oxidative stress,cell proliferation,differentiation and apoptosis. OBJECTIVE:This paper focuses on FoxO1,and by summarizing its upstream and downstream regulatory mechanisms,it provides new ideas for the future treatment of bone-related diseases. METHODS:The search terms"FoxO1,Bone"were used for literature retrieval in CNKI and WanFang Databases,and the search terms"FoxO1,Bone,Skeleton"were used in PubMed and Web of Science databases.The old,repetitive,poor quality and irrelevant papers were excluded,and 56 papers were finally included for review and analysis. RESULTS AND CONCLUSION:(1)FoxO1 promotes the differentiation of bone marrow mesenchymal stem cells into osteoblasts by increasing the expression of runt-related transcription factor 2,alkaline phosphatase and osteocalcin,and transforms bone marrow mesenchymal stem cells from lipogenic differentiation to osteogenic differentiation by inhibiting peroxisome proliferator-activated receptor γ,thereby increasing bone formation.In addition,FoxO1 may also affect bone formation by increasing the number of osteoblasts.(2)Inhibition of FoxO1 in bone marrow mononuclear macrophages can reduce the expression of macrophage colony-stimulating factor,receptor activator of nuclear factor-κB ligand and nuclear factor of activated T cells 1,promote the expression of FoxO1 in osteoclasts,and thus inhibit osteoclast differentiation.In addition,direct activation of FoxO1 also inhibits osteoclast differentiation and weakens osteoclast activity.(3)Upregulation of FoxO1 in chondrocytes can regulate chondrocyte homeostasis,protect chondrocytes from oxidative stress,and promote the expression of autophagy related genes and the secretion of proteoglycan 4 by chondrocytes.(4)This paper details the molecular mechanism of FoxO1 regulation in different bone cells in detail,and elaborates the key role of FoxO1 in the treatment of bone-related diseases more comprehensive and deeply,providing new ideas for the treatment of osteoarthritis,osteoporosis,delayed fracture healing and other bone-related diseases.

ObjectiveTo evaluate pharmacological effects of Shengmai injection（SMI）on cerebral ischemia and study its neuroprotective mechanism. MethodsMale specific pathogen-free （SPF） Sprague-Dawley （SD） rats were randomly divided into a sham group， a model group， a low-dose SMI group（3 mL·kg^-1）， a middle-dose SMI group（6 mL·kg^-1）， a high-dose SMI group（12 mL·kg^-1）， and a Ginaton group（4 mL·kg^-1）according to the random number table method， with 12 rats in each group. The rat model of cerebral ischemia-reperfusion（MCAO/R）was prepared via the suture method. The administration groups were intraperitoneally injected with corresponding concentrations of SMI or Ginaton injection after reperfusion， which was conducted for 3 consecutive days. The sham group and model group were administered the equivalent volume of physiological saline. The pharmacological effects of SMI on brain injury in MCAO/R rats were evaluated by neurological function scores， cerebral infarction area， hematoxylin-eosin （HE） staining， Nissl staining， terminal deoxynucleotidyl transferase dUTP nick-end labeling （TUNEL） staining， and Western blot. The dominant link and key protein of SMI treating cerebral injury were explored using proteomic analysis. The related mechanisms of SMI were further validated using enzyme-linked immunosorbent assay （ELISA）， Western blot， and chloride ion fluorescence probe with oxygen-glucose deprivation/reoxygenation（OGD/R）-treated PC12 cells and MCAO/R rats. ResultsCompared with the sham group， the model group showed significantly increased neurological function scores， cerebral infarction area， neuronal apoptosis rate， and expression levels of apoptosis related proteins （P<0.05， P<0.01）and significantly decreased density of Nissl bodies and neurons（P<0.01）. Compared with the model group， the SMI groups exhibited significantly decreased neurological function scores， cerebral infarction area， neuronal apoptosis rate， and expression levels of apoptosis related proteins （P<0.05， P<0.01）and significantly increased density of Nissl bodies and neurons （P<0.05）. The proteomic analysis results showed that oxidative stress and inflammatory response were important processes of SMI intervening in MCAO/R injury， and the chloride intracellular channel protein 1 （CLIC1） was one of key proteins in its action network. The levels of representative indicators of oxidative stress and inflammatory response in the MCAO/R rats of the SMI groups were significantly reduced， compared with those in the model group（P<0.05， P<0.01）， and the expression levels of CLIC1 and downstream NOD-like receptor protein 3 （NLRP3） decreased （P<0.01）. In addition， the experimental results based on the OGD/R PC12 cells showed that SMI significantly increased the cell survival rate（P<0.01） and significantly decreased the intracellular chloride ion concentration（P<0.05）. ConclusionSMI has neuroprotective effects. Oxidative stress and inflammatory response are key processes of SMI intervening in MCAO/R injury. The potential mechanism is closely related to the regulation of CLIC1.

OBJECTIVE To evaluate the efficacy， safety and economics of the centrally procured generic versus original esomeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding （ANVUGIB）. METHODS A retrospective collection of real-world clinical data was conducted for ANVUGIB patients who received treatment at Shenzhen People’s Hospital and University of Hong Kong-Shenzhen Hospital from January 2018 to March 2024. Patients were divided into imported original drug group （original drug group， 221 cases） and centrally procured generic drug group （generic drug group， 75 cases） according to the types of drug used. Propensity score matching （PSM） was performed at a ratio of 3∶1 to compare the clinical efficacy， safety and economics between the two groups. RESULTS Totally 241 patients were included after PSM， with 170 in the original drug group and 71 in the generic drug group. There were no significant differences between the two groups in terms of rebleeding rate， rate of second endoscopic intervention， blood transfusion rate， length of hospital stay， mortality due to gastrointestinal bleeding， 30-day readmission due to rebleeding， and overall survival rate （P＞0.05）. The incidence of adverse events among all patients in both groups also showed no statistically significant difference （P＞0.05）； furthermore， the adverse events reported by the respective hospitals to the National Center for ADR Monitoring were comparable between the two groups. After PSM， the median total drug cost and high-dose esomeprazole cost in the generic drug group were significantly lower than those in the original drug group， while the median nursing fee and bed fee were significantly higher than those in the original drug group （P＜0.05）. There was no statistically significant difference between the two groups in terms of median total hospitalization expenses， total treatment costs， laboratory fees， examination fees， material costs， or consultation fees （P＞0.05）. CONCLUSIONS The clinical efficacy and safety of centrally procured generic esomeprazole in the treatment of ANVUGIB are comparable to those of the original drug， and it is more economical.

Objective:This study aims to analyze the threshold changes in distortion product otoacoustic emissions（DPOAE） and auditory brainstem response（ABR） in adult Otof-/- mice before and after gene therapy, evaluating its effectiveness and exploring methods for assessing hearing recovery post-treatment. Methods:At the age of 4 weeks, adult Otof-/- mice received an inner ear injection of a therapeutic agent containing intein-mediated recombination of the OTOF gene, delivered via dual AAV vectors through the round window membrane（RWM）. Immunofluorescence staining assessed the proportion of inner ear hair cells with restored otoferlin expression and the number of synapses.Statistical analysis was performed to compare the DPOAE and ABR thresholds before and after the treatment. Results:AAV-PHP. eB demonstrates high transduction efficiency in inner ear hair cells. The therapeutic regimen corrected hearing loss in adult Otof-/- mice without impacting auditory function in wild-type mice. The changes in DPOAE and ABR thresholds after gene therapy are significantly correlated at 16 kHz. Post-treatment,a slight increase in DPOAE was observeds,followed by a recovery trend at 2 months post-treatment. Conclusion:Gene therapy significantly restored hearing in adult Otof-/- mice, though the surgical delivery may cause transient hearing damage. Precise and gentle surgical techniques are essential to maximize gene therapy's efficacy.

OBJECTIVE To evaluate the therapeutic efficacy and safety of vonoprazan-based triple therapy in treatment-naive patients with Helicobacter pylori （Hp） infection. METHODS From March 2022 to August 2023， 198 treatment-naive patients with Hp infection treated at the outpatient service of department of gastroenterology in our hospital were assigned to the vonoprazan- based triple therapy group （VAC group， n＝98） and the bismuth-based quadruple therapy group （BQT group， n＝100） using the random number table method. Patients in VAC group were given Vonoprazan fumarate tablets （20 mg） + Amoxicillin capsules （1 g） + Clarithromycin tablets （0.5 g）， all twice daily. Patients in BQT group were given Esomeprazole magnesium enteric-coated tablets （20 mg， twice daily） + Metronidazole tablets （0.4 g， four times daily） + Tetracycline tablets （0.5 g， three times daily） + Bismuth potassium citrate capsules （0.6 g， twice daily）. The treatment course for both groups was 14 days. The Hp eradication rates were compared between the two groups in intention-to-treat （ITT）， modified intention-to-treat （MITT）， and per-protocol （PP） analysis sets， while adverse reaction occurrence and medication compliance of two groups were recorded. RESULTS In the ITT， MITT and PP analyses sets， the Hp eradication rates in VAC group were non-inferior to those in BQT group. The incidences of grades 1-2 nausea， vomiting， and loss of appetite in VAC group were significantly lower than in BQT group， and the proportion of patients with good compliance was significantly higher in VAC group （P＜0.05）. Regardless of whether the body mass index （BMI） ≤25 kg/m2 or ＞25 kg/m2， no statistically significant difference was observed in the Hp eradication rates between the two groups （P＞0.05）. CONCLUSIONS Vonoprazan-based triple therapy is non-inferior to bismuth-based quadruple therapy in the treatment of treatment-naive patients with Hp infection， with higher safety and good patient medication compliance. BMI has no significant impact on the Hp eradication rate.

Objective To explore the differential gene expression profile and small molecule drugs for chronic atrophic gastritis(CAG)by bioinformatics technology.Methods Two gene expression samples of CAG chips(GSE27411,GSE116312)were obtained through the Gene Expression Synthesis(GEO)database,screen the differentially expressed genes(DEGs)of CAG by R language,and CAG immune-related genes were obtained for gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis.Protein-protein interaction(PPI)network was constructed using STRING database to screen out core genes,further study on immune invasion of core genes based on GSE27411 dataset,small molecular compounds interacting with core genes were predicted,molecular docking was carried out by MOE2022,and survival analysis was carried out by GEPIA2 website.Results A total of 517 DEGs were screened out based on GEO database.GO function enrichment analysis found that it mainly involved in granulocyte chemotaxis、leukocyte chemotaxis and neutrophil chemotaxis biological processes.KEGG pathway enrichment analysis showed that it mainly involved in cytokine-cytokine receptor interaction、nuclear factor kappa B signaling pathway、interleukin-17 signaling pathway.Six key genes of NR1H4、CCK、CCL20、CXCL1、LCN2、SAA1 were obtained by PPI network,through relevant verification,NR1H4 was regarded as the core gene.Immune cell infiltration analysis showed that central memory CD8 T cell、effector memeory CD4 T cell、gamma delta T cell、natural killer T cell、neutrophil and other immune cells may be involved in the development of CAG,and the neutrophil was positively correlated with NR1H4.It was predicted that six small molecular drugs,corilagin,stigmasterol,geniposide,tangeretin,chenodeoxycholic acid and epigallocatechin 3-gallate,have good binding force with NR1H4.Conclusion The potential mechanism of CAG is preliminarily explored in this study,the key gene of NR1H4 and neutrophil may play an important role in the"inflammatory cancer transformation"process of CAG,which can provide a certain reference for the study of the"inflammatory cancer transformation"mechanism of CAG.

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

Objective:To explore the impact of uncertain resection on postoperative survival in non-small cell lung cancer.Methods:This is a retrospective cohort study. A retrospective analysis was conducted on the data of 477 patients with non-small cell lung cancer who underwent lobectomy in the Department of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from December 2012 to December 2013. There were 302 males and 175 females, aged (59±8) years (range: 27 to 79 years). According to the surgical resection criteria issued by the International Association for the Study of Lung Cancer, the patients were divided into the intact resection group (R0 group, 286 cases) and the uncertain resection group (R (un) group, 191 cases). Clinical data between the two groups were compared using χ2 test, and propensity score matching (PSM) was performed on patients using the R language, with matching variables including gender, age, smoking history, adjuvant therapy, TNM stage, pathological type, and tumor site. The nearest-neighbor method was used for 1∶3 matching and the caliper value was 0.02. The survival curve was plotted using the Kaplan-Meier method and compared using the Log-rank test. The Cox proportional hazards regression model was used to identify risk factors in overall survival (OS). Subgroup analysis was based on TNM staging and mediastinal lymph node metastasis status. Results:In the R (un) group, 68 patients had positive lymph in the highest group and 129 patients did not undergo complete dissection of the mediastinal lymph nodes. The baseline data for the R0 group and the R (un) group were corrected using PSM, and a total of 369 patients were successfully matched, including 227 cases in the R0 group and 142 cases in the R (un) group. After PSM, the 5-year survival rates of the R0 group and the R (un) group were 64.3% and 52.1%, respectively ( P=0.021). The 5-year survival rates of stage Ⅰ, Ⅱ, and Ⅲ patients were 85.2%, 65.9%, and 34.8%, respectively ( P<0.01). TNM stage ( χ2=46.913, P<0.01), pathological classification of adenosquamous cell carcinoma ( HR=5.970, 95% CI: 3.117 to 11.431, P<0.01) and R (un) resection ( HR=1.512, 95% CI: 1.065 to 2.147, P=0.021) were prognostic factors for postoperative survival. Subgroup analysis showed that in stage Ⅲ patients, 5-year survival rates of the R0 group and the R (un) group after resection were 45.8% and 9.5%, respectively ( P=0.002). Among patients with mediastinal lymph node metastasis, 5-year survival rates of the R0 group and the R (un) group were 50.6% and 7.1%, respectively ( P<0.01). Conclusions:TNM staging, pathological type, and R (un) resection are prognostic factors for overall postoperative survival in non-small cell lung cancer. In stage Ⅰ and Ⅱ patients, R (un) is not a prognostic factor for postoperative survival of non-small cell lung cancer. In patients with stage Ⅲ and mediastinal lymph node metastasis, R (un) is a prognostic factor for non-small cell lung cancer after surgery.
