This paper reviewed the development history of doctor-patient shared decision-making （SDM） at home and abroad， emphasizing the importance of cross-cultural analysis in constructing a Chinese doctor-patient SDM model. It also delved into the relationship between Western “individualistic” sociocultural values and doctor-patient SDM， as well as the influence of China’s “collectivist” sociocultural values on doctor-patient SDM， revealing significant disparities in doctor-patient SDM models under distinct sociocultural contexts. Although the doctor-patient SDM theory in China originated from the West， this theory requires profound “collision” and adaptation with local Chinese culture to form a localized theory suited to China’s national conditions. Through cross-cultural adaptation and integrating China’s familism tradition and medical ethics concepts， the future construction of the doctor-patient SDM model in China should emphasize family members’ involvement and seek cultural balance to facilitate its widespread application in clinical practice.

OBJECTIVE:The main clinical manifestations of knee osteoarthritis are pain,swelling,stiffness,and limited activity,which have a serious impact on the life of patients.Exercise therapy can effectively improve the related symptoms of patients with knee osteoarthritis.This paper uses the method of network meta-analysis to compare the efficacy of different exercise types in the treatment of knee osteoarthritis. METHODS:CNKI,WanFang,PubMed,Embase,Cochrane Library,Web of Science,Scopus,Ebsco,SinoMed,and UpToDate were searched with Chinese search terms"knee osteoarthritis,exercise therapy"and English search terms"knee osteoarthritis,exercise".Randomized controlled trials on the application of different exercise types in patients with knee osteoarthritis from October 2013 to October 2023 were collected.The outcome measures included visual analog scale,Western Ontario and McMaster Universities Osteoarthritis Index score,Timed Up and Go test,and 36-item short form health survey.Literature quality analysis was performed using the Cochrane Manual recommended tool for risk assessment of bias in randomized controlled trials.Two researchers independently completed the data collection,collation,extraction and analysis.RevMan 5.4 and Stata 18.0 software were used to analyze and plot the obtained data.

Objective To evaluate the efficacy and safety of obinutuzumab(OBZ)in the treatment of refractory primary membranous nephropathy(pMN).Methods The clinical data of 15 patients with refractory pMN who received OBZ treatment in Department of Nephrology of The First Affiliated Hospital of Naval Medical University between Jan.2022 and Sep.2024 were retrospectively analyzed,and they included basic information,relevant laboratory indexes,clinical and immunological outcomes,and adverse events.Results Among the 15 patients with refractory pMN,14(93.3％)were phospholipase A2 receptor(PLA2R)-associated membranous nephropathy(10 cases with positive PLA2R by renal biopsy and 4 cases with no recorded PLA2R results by renal biopsy but with positive serum PLA2R antibodies).During the follow-up period,all 15 patients achieved clinical remission,with 4(26.7％)patients achieving complete remission and 11(73.3％)patients achieving partial remission.Of the 12 patients with positive serum PLA2R antibodies,11 patients had continuously positive serum PLA2R antibodies before OBZ treatment,and 9(81.8％)patients achieved immunological remission after OBZ treatment.All the 15 patients had previously received immunosuppressive therapy,and all of them were classified as refractory pMN,with 7(46.7％)patients having been treated with cyclophosphamide combined with corticosteroids,2(13.3％)patients having been treated with calcineurin inhibitor combined with corticosteroids,11(73.3％)patients having received rituximab.During the treatment,2(13.3％)cases of adverse events were observed:1 patient experienced transient liver dysfunction,and the transaminase returned to normal after discontinuing atorvastatin;another patient developed a positive T-cell spot test for Tuberculosis infection during the intertreatment interval and successfully completed the subsequent OBZ treatment and achieved clinical remission after treatment with isoniazid and rifampicin.Conclusion OBZ demonstrates favorable clinical efficacy in the treatment of refractory pMN,with a low incidence of adverse events.

When conducting extravehicular activities under low-gravity conditions like on the moon,the weight of the spacesuit is one of the loads that human body has to bear.The centroid position of the spacesuit will affect the motion control of the human-spacesuit system.In order to reveal the influence of the centroid position of the lunar spacesuit on human motion under lunar-gravity,a suspended 1/6 gravity simulation system was used for the experiment.When subjects were under different load centroids which include front and back on sagittal plane,left and right on coronal plane,up and down on cross-section plane,near to coordinate origin,the postures and plantar pressures of subjects during three typical movements:standing,single-knee standing and walking were captured.Inverse dynamics solution is adopted to analyze the joint torques of human body in above conditions.Combined with the subjective evaluation,the appropriate load centroid area was analyzed by comparative.The experiment shows that,human is non-sensitive to the up and down change of load centroid,the after is back change,the front and right load centroid are the mostly avoided.The results obtained by this study will provide a reference for the layout design of the lunar spacesuit.

Objective:s To investigate the risk factors for delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) in patients with acute carbon monoxide poisoning (ACOP) and to develop predictive models based on machine learning algorithms.Methods:Patients with ACOP hospitalized at the First Affiliated Hospital of Zhengzhou University from August 2019 to October 2024 were included, with the occurrence of DEACMP as the outcome measure. The dataset was randomly divided into training and validation sets at a ratio of 7:3. Lasso regression was used to select features influencing the outcome in training sets. Nine machine learning models—including Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Support Vector Machine (SVM)—were constructed. Receiver operating characteristic (ROC) curves were plotted and the area under the curve (AUC) calculated for each model. Calibration curves were used to assess accuracy, and decision curve analysis (DCA) was applied to evaluate clinical utility. The SHapley Additive exPlanations (SHAP) method was employed to visualize and interpret the best-performing model.Results:A total of 264 ACOP patients were included, of whom 54 (20.5%) developed DEACMP. Lasso regression identified eight key feature variables. Based on these factors, predictive models were constructed, showing good AUC stability across the nine machine learning models in both training (0.92–0.99) and validation sets (0.85–0.91). The RF model performed best, with an AUC of 0.99 in the training set and 0.90 in the validation set; its calibration curve and DCA curve also demonstrated excellent performance. SHAP analysis of the RF model revealed the importance ranking of factors from highest to lowest as follows: Glasgow Coma Scale (GCS) score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, diastolic blood pressure (DBP), and drinking history.Conclusions:The RF model exhibited the highest predictive performance for DEACMP occurrence in ACOP patients. The influencing factors, ranked in order of importance from highest to lowest, are as follows: GCS score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, DBP, and drinking history.

OBJECTIVE To investigate the in vitro inhibitory mechanism of berberine on the proliferation of tumor stem cells and evaluate its in vivo safety. METHODS Flow cytometry was used to select tumor stem cells from mouse skin melanoma B16F10 cells； CD44， CD133， Nanog homologous box protein （NANOG） and octamer-binding transcription factor 4 （OCT4） were used as indicators to characterize tumor stem cells. Tumor stem cells were divided into control group， all-trans retinoic acid （ATRA） group， and berberine group， and the CCK-8 method was used to detect the effects of berberine on the viability of tumor stem cells； flow cytometry was adopted to detect cell apoptotic rate， the proportion of CD44+/CD133+ and the positive cell rate of sex determining region Y box protein 2 （SOX2）； the morphological changes of tumor balls were recorded after treatment with berberine； the morphology of cell pyroptosis in each group was recorded， and the release rate of lactate dehydrogenase （LDH） was detected； Western blot assay was adopted to detect the expressions of pyroptosis-related protein gasdermin E （GSDME）， GSDME- N， caspase-3 and cleaved caspase-3. Preliminary evaluation of in vivo safety of berberine was conducted by using zebrafish embryo toxicity experiments. RESULTS Compared with B16F10 cells， the proportion of CD44+/CD133+ cells in tumor stem cells and the fluorescence intensity of NANOG and OCT4 were significantly increased （P＜0.000 1）. The half-inhibitory concentration of berberine to tumor stem cells was 50.98 μmol/L. Compared with the control group， the apoptotic rate of cells in the berberine group was significantly increased， while the proportion of CD44+/CD133+ cells and the rate of SOX2 positive cells were reduced significantly （P＜0.000 1）； tumor stem cell spheroids were atrophied， with partial cell death. After treatment with berberine， tumor stem cells exhibited swelling in their outermost layer， the release rate of LDH of cells was significantly increased and the release rate of LDH increased with increasing dose； the protein expressions of GSDME-N and cleaved-caspase-3 of cells in berberine 20， 40 μmol/L groups were significantly increased， and the protein expressions of GSDME and caspase-3 were significantly reduced （except for berberine 20 μmol/L group， P＜0.05）. The embryonic development of zebrafish treated with berberine was almost unaffected， and the survival rate of embryo reached 100%， with no obvious abnormalities observed. CONCLUSIONS Berberine has good activity against the proliferation of tumor stem cells， and its mechanism of action may be related to activating GSDME and promoting cell pyroptosis； berberine has good in vivo safety.

Drugs and physical stimulation,including light,electricity,and magnetic fields,can be used to influence how neurons operate,among which chemogenetic and optogenetic technologies are most widely used.In recent years,magnetogenetic technology has also been developed that can acti-vate neurons in magnetic fields through magnetic sensitive actuators,leading to non-invasive and instanta-neous activation of specific brain regions.This article reviews the evolution of and problems with chemoge-netic and optogenetic techniques commonly used in brain science research.It also outlines the latest progress in magnetogenetic technologies,which are not full-fledged yet,as well as the role of transcra-nial electrical stimulation,transcranial magnetic stimulation,deep brain stimulation and transcranial ultra-sound stimulation technology in the functional regulation of brain diseases.Constant adjustment and improvement can make it possible for these technologies to be used more widely for the study of brain sciences and the treatment of brain diseases.

Purpose To evaluate the consistency and repeatability of cerebral blood flow(CBF)values measured by automatic segmentation of region of interest(ROI)and arterial spin labeling(ASL)functional image fusion in hippocampal sclerosis patients with medial temporal lobe epilepsy.Materials and Methods From January 2021 to October 2022,a total of 52 patients with medial temporal lobe epilepsy confirmed by MRI or pathology in General Hospital of Ningxia Medical University were retrospectively collected.All subjects were scanned on 3.0T MRI to obtain axial T1 weighted three-dimensional magnetization reserve gradient echo(3D-T1W1-MPGAGE)sequence and three-dimensional pseudo continuous ASL sequence.The 3D-T1W1-MPGAGE imaging were automatically segmented.Two physicians used the freeview visualization interface of freeSurfer software to fuse the ROI and ASL functional images of the hippocampal subregions and to measure the CBF values.The intra-observer and inter-observer consistency and repeatability were evaluated and analyzed.The consistency analysis and repeatability evaluation were performed via intraclass correlation coefficient(ICC),Bland-Altman diagram and Wilcoxon rank sum test.Results The ICC of CBF values measured by two physicians were all>0.750,with an average of 0.868±0.095.The ICC of left and right hippocampal subregions were as follows:subiculum(SUB):0.818/0.801,cornu ammonis(CA)1:0.920/0.907,CA2-3:0.759/0.978,CA4:0.757/0.758 and dentate gyrus(DG):0.990/0.991;The ICC delineated by the same physician's ROI were all>0.990 with an average of 0.994±0.002.The ICC of left and right hippocampal subregions were as follows:SUB:0.993/0.993,CA1:0.996/0.995,CA2-3:0.989/0.994,CA4:0.992/0.995 and DG:0.993/0.996.The Bland-Altman diagram showed the scatter distribution and consistency,and the coefficient of repeatability was obtained.The same observer had certain repeatability for the fusion measurement of automatic segmentation ROI and ASL functional images.Conclusion The CBF values measured by fusing ROI and ASL functional images of automatically segmented hippocampal subregion have higher consistency and repeatability.

ObjectiveTo explore the molecular mechanism of Sanhuang Xiexintang （SHXXT） in protecting stress gastric ulcer （SGU） in rats through network pharmacology， molecular docking， and animal experiments. MethodThe active ingredients and corresponding targets in SHXXT were collected and screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Traditional Chinese Medicine Information Database （TCMID）， Bioinformation Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）， and Swiss Target Prediction database. SGU-related targets were screened from the Online Mendelian Inheritance in Man （OMIM）， Therapeutic Target Database （TTD）， GeneCards database， and PharmGKB database. Herbal-ingredient-target （H-C-T） network was constructed by using Cytoscape 3.9.1 software. Protein-protein interaction （PPI） of drug and disease intersection targets was analyzed by using the Protein Interaction Platform （STRING） database. Gene ontology （GO） enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis were conducted through the Database for Annotation Visualization and Integrated Discovery （DAVID）. The active ingredients and key targets were validated using AutodockVina 1.2.2 molecular docking software， and the experimental results were further validated through animal experiments. ResultThe 55 active ingredients were screened， and 255 potential target genes for SHXXT treatment of SGU were predicted. The PPI analysis showed that protein kinase B （Akt）， phosphatase and tensin homolog deleted on chromosome ten （PTEN）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and cyclooxygenase-2 （COX-2） are the core targets of SHXXT for protecting SGU. GO and KEGG analyses showed that SHXXT may affect the development of SGU by regulating various biological processes such as the phosphoinositide 3-kinase （PI3K）/Akt signaling pathway and inflammatory processes. The molecular docking results showed that both the active ingredients and key targets had good binding ability. Animal experiments showed that compared with the blank group， the ulcer index （UI） of the model group was significantly increased （P<0.01）， and the serum levels of TNF-α and IL-1β significantly increased （P<0.01）. The phosphorylation level of PTEN in gastric mucosal tissue was significantly down-regulated （P<0.05）. The phosphorylation levels of PI3K， Akt， and nuclear factor kappa-B （NF-κB） were significantly up-regulated （P<0.05）. Compared with the model group， the UI of the treatment group was significantly reduced （P<0.01）， and the serum levels of TNF-α and IL-1β were significantly reduced （P<0.01）. The phosphorylation level of PTEN in gastric mucosal tissue was significantly up-regulated （P<0.01）， and the phosphorylation levels of PI3K， Akt， and NF-κB were significantly downregulated （P<0.01）. ConclusionThe application of network pharmacology prediction， molecular docking simulation， and animal experimental validation confirms that SHXXT regulates the PI3K/Akt/NF-κB signaling pathway to regulate the inflammatory response of rats and thus protects the gastric mucosa of SGU rats.

Objective:To elucidate the primary elements pertaining to the perception of relapse risk and to in-vestigate the characteristics and alterations of perception of the risk of recurrence in patients with schizophrenia.Methods:By using the method of phenomenological study,semi-structured in-depth interviews were conducted among schizophrenic patients with first onset,first recurrence and multiple recurrences.Twenty-three 23 outpatient and inpatient cases that met the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were included,and all patients had PANSS scores below 60.The interview data were collated and analyzed according to Colaizzi analysis.Results:The perception of recurrence risk in patients with schizophrenia en-compassed 4 major themes and 11 sub-themes,namely susceptibility(limited overall understanding,transition from optimism to objectivity),detection of early warning symptoms(dynamic escalation,assistance from family mem-bers in identification),understanding risk factors(lack of understanding,the relationship between psychosocial fac-tors and relapse,dynamic understanding of medication-relapse relationship),and apprehension of the consequences of recurrence(care burden and financial constraints,impaired social functioning and maladjustment,impact on pub-lic safety,personal health risks).Conclusion:The content of risk perception of recurrence in patients with schizo-phrenia is relatively substantial.The overall level of risk perception of recurrence in patients with schizophrenia is low.
