BackgroundIndividuals with schizophrenia are prone to higher rates of hospital readmission， presenting significant clinical challenges and imposing considerable social burdens within the mental health domain. In recent years， various risk prediction models have been developed to forecast readmission in patients with schizophrenia and support clinical decision-making， but their predictive performance and clinical applicability require comprehensive evaluation. ObjectiveTo systematically evaluate the risk prediction models for readmission in patients with schizophrenia， so as to provide insights for the development of high-performance and highly applicable readmission risk prediction models for patients with schizophrenia. MethodsOn July 5， 2025， a systematic literature search was conducted across multiple electronic databases， including PubMed， Embase， Cochrane Library， Web of Science， CINAHL， CNKI， China Biomedical Literature Database， Wanfang Database， and VIP Database， to identify risk prediction models for readmission in patients with schizophrenia. The search period was from the establishment of the databases to July 1， 2025. Two researchers independently performed literature screening， data extraction， risk of bias assessment， and applicability assessment. ResultsA total of 9 studies were included in this review， encompassing 18 risk prediction models for readmission in patients with schizophrenia. Among them， 4 models reported the area under the receiver operating characteristic （ROC） curve （AUC）， ranging from 0.734 to 0.820， 16 models provided AUC values of 0.642–0.879 for internal validation， and 1 model demonstrated an AUC of 0.841 for external validation. Key predictors included disease duration and the concomitant therapy of antipsychotic medications. The risk of bias was assessed as "high" in all included studies. ConclusionThe development of risk prediction models for readmission in patients with schizophrenia remains in an exploratory stage. Although the model exhibits favorable predictive performance， it is associated with a high risk of bias and insufficient performance evaluation.

Objective To conduct a multidimensional and multi-level evaluation of the comprehensive clinical value of empagliflozin in the treatment of type 2 diabetes mellitus.Methods Based on the National Essential Medicines List(2018 Edition),dapagliflozin was selected as the control.A comprehensive clinical evaluation index system was established through literature review,focus group interviews and in-depth expert interviews,encompassing six dimensions:safety,efficacy,economy,suitability,innovation,and accessibility.The Delphi method and hierarchical direct weighting method were used to screen indicators and determine their weights.Evidence for each indicator was collected and integrated both qualitatively and quantitatively through literature research,real-world studies,and pharmacoeconomic evaluations.Experts scored the indicators based on the collected evidence,and a total score for the comprehensive clinical evaluation of empagliflozin was calculated by combining these scores with indicator weights,followed by a comparative analysis with dapagliflozin.Results A comprehensive clinical evaluation of empagliflozin in the treatment of type 2 diabetes mellitus was successfully established,consisting of 6 primary indicators,14 secondary indicators,and 41 tertiary indicators.The overall evaluation score for empagliflozin was 90.35,and 89.47 for dapagliflozin.Conclusion The comprehensive clinical value of empagliflozin in the treatment of type 2 diabetes mellitus is slightly higher than that of dapagliflozin.This finding can serve as a reference for rational clinical drug use and related decision-making.

Objective To screening and validation of key genes for programmed cell death(PCD)in gout through bioinformatics and machine learning and immunoinfiltration analysis.Methods Gout-related datasets were obtained from the Gene Expression Omnibus(GEO)database,comprising the human gout dataset GSE160170 and murine gout dataset GSE190138,which served as the training cohort.Differentiall expression genes(DEGs)were screened with difference factor>2 and P<0.05.The DEGs of two data sets were intersected to obtain the common DEGs(co-DEGs).The co-DEGs were enriched by GO function and KEGG pathway analysis.The combination of co-DEGs and PCD related gene set was used to obtain PCD related DEGs.A PPI network was built in the STRING database.The key module genes were screened in Cytoscape's MCODE,the hub genes were screened in 12 algorithms built into the Cytohubba plugin,including Degree,MCC,DMNC,MCN,EPC,BottleNeck,EcCentricity,closness,Radiality,Betweeness,Stress and Clusteringcoefficoent,the common genes of the two was as candidate genes.The regression model of least absolute shrinkage and selection operator(LASSO)was used to screen key genes in the GSE160170 and GSE190138 data sets respectively,and the intersection of the two was adopted to obtain key genes.The diagnostic value of key genes in gout was evaluated by receiver operating characteristic(ROC)curve.The expression difference of gout related immune cells was investigated by single sample gene set enrichmemt analysis(ssGSEA)immunoinfiltration analysis.Finally,blood samples from 30 gout patients admitted to the Department of Rheumatology,Xi'an Fifth Hospital from February to April 2024 were collected as the experimental group,while blood samples from 30 healthy subjects were collected as the control group.RNA was extracted from the Peripheral blood mononuclear cell(PBMC).Quantitative real time polymerase chain reaction(RT-qPCR)was used to validate the expression of key genes in clinical samples.Results 53 common DEGs of GSE160170 and GSE190138 were obtained,among which 43 genes were up-regulated and 10 were down-regulated.GO and KEGG indicated that most genes were involved in cell death,apoptosis,interlenkin(IL)-17 signaling pathway,tumor necrosis facter(TNF)signaling pathway and nucleotide-binding oligomerization domain-(NOD)-like receptor signaling pathway.12 co-DEGs of programmed cell death and gout were obtained.A total of 7 candidate genes were screened.LASSO regression model screened 5 genes and 4 genes respectively in two datasets,and 3 key genes were abtained by the intersection of the two datasets,which were IL-6,plasminogen activator urokinase receptor(PLAUR)and NOD-like receptor thermal protein domain associated protein3(NLRP3).Validation within the training set revealed that all three genes attained perfect diagnostic performance for gout,with area under the ROC(AUC-ROC)curve values of 1.00.Immunoinfiltration analysis showed that the changes of activated CD4+T cells,activated CD8+T cells and natural killer cells were closely related to the occurrence and development of gout.In the clinical samples,compared with the control group,PLAUR,NLRP3 and IL-6 were highly expressed in gout patients,and the differences were statistically significant(t=18.852,9.633,8.293,all P＜0.05).Conclusion IL-6,PLAUR and NLRP3 provide potential biomarkers and therapeutic targets for the diagnosis and treatment of gout,offering new directions in this field.

This study investigated the prevalence and potential mechanisms of gentamicin heterore-sistance in Streptococcus isolates from dairy cows.In this study,A total of 39 Streptococcus isola-ted from raw milk were collected,and the minimum inhibitory concentration(MIC)of gentamicin and other drugs on the isolates was determined by micro broth dilution method,and the K-B paper diffusion method,colony analysis profile(PAP),and resistance stability test were used to investigate the heteroresistance characteristics of Streptococcus,and the mechanism of heteroresis-tance was analyzed based on whole genome sequencing and resequencing.Seven suspected heterore-sistance strains were identified by K-B paper diffusion method,accounting for 17.95％(7/39)of the total number of suspected strains.PAP confirmed that the MIC to MNIC ratio of L147,L108 and L174 was greater than 8,and the frequency of resistant subgroups ranged from 1.38×10-5 to 8.18 × 10-5,which was greater than 1 × 10-7,confirming that they were heteroresistance strains.Resistance stability tests revealed that the resistant subpopulations of all three strains were not stably inherited.Whole-genome sequencing revealed mutations in the ribosomal target genes of aminoglycoside antibiotics,rsmA,rsmB and rsmE,compared with the reference genome,which may lead to heteroresistance to gentamicin in Streptococcus.The occurrence of heteroresistance of Streptococcus to gentamicin is high in dairy sources,so more attention should be paid to the occur-rence of heteroresistance when using gentamicin for clinical treatment.

Objective:To evaluate the perceived level of home exercise behavior in elderly patients with ovarian cancer and analyze its influencing factors, so as to promote home exercise behavior of patients and improve the quality of life.Methods:A total of 227 elderly patients with ovarian cancer from January 1, 2021 to October 1, 2023 in the First Affiliated Hospital, School of Medicine, Zhejiang University were selected by convenience sampling method. A cross-sectional survey was conducted by General Information Questionnaire, Exercise Benefits/Barriers Scale (EBBS), Social Support Rating Scale (SSRS), General Self-efficacy Scale (GSES) and Brief Fatigue Inventory (BFI). The influencing factors on the perceived level of home exercise behavior in elderly patients with ovarian cancer were analyzed.Results:There were 227 elderly female patients with ovarian cancer, including 151 patients aged<70 years old and 76 patients aged ≥70 years old. The scores of EBBS, SSRS, GSES, BFI were (123.37±11.02), (37.68±7.44), (29.35±6.54), (5.82±2.01) points. The perception of exercise behavior was positively correlated with general self-efficacy and social support ( r=0.752, 0.901, both P<0.01), was negatively correlated with cancer-related fatigue ( r=-0.198, P<0.01). The results showed that general self-efficacy, social support, age≥70 years old, no spouse, not being informed of the benefits of exercise,fatigue due to moderate and severe cancer, duration of disease ≥12 months were the influencing factors ( t values were -4.56 - 4.46, all P<0.05). Conclusions:Elderly patients with ovarian cancer need to improve their perception level of home exercise behavior. In the formulation of home exercise behavior for elderly patients with ovarian cancer, education and cognition on the perceived benefits of home exercise behavior should be strengthened, and patients′ physical and mental status should be evaluated before exercise to actively reduce cancer-related fatigue. At the same time, the combination of family support can improve the perceived level of exercise behavior of elderly patients with ovarian cancer at home, so as to promote home exercise behavior of patients.

Objective:To evaluate the clinical status of long-term oral anticoagulant management in patients with atrial fibrillation, and to analyze the obstacles and promoting factors in the implementation of evidence, so as to provide evidence for clinical transformation.Methods:This study was a cross-sectional study. Through the evidence-based nursing method, guided by the Ottawa Model, the review indicators and review methods were developed based on the best evidence. The clinical status review of 100 patients who met the inclusion criteria in the Department of Cardiology, Affiliated Hospital of Jiangsu University was conducted from August to November 2022 using a convenience sampling method, and based on the results of the review, an analysis of obstacles and promoting factors was carried out to develop a clinical response.Results:This study included 100 patients with atrial fibrillation, 60 males and 40 females, aged (70.14 ± 10.39) years. Totally 26 best items were included, and 24 review indicators were developed, among which only 4 indicators had a compliance rate of 100% , 2 indicators had a compliance rate of >60% , 5 indicators had a compliance rate of <60% , and 13 indicators had a compliance rate of 0. According to the results of the review, a comprehensive and systematic analysis was conducted from the three dimensions of system, practitioners, patients and family members. For each dimension, obstacles and promoting factors were analyzed in depth from evidence-based change, potential adopters and practical environment.Conclusions:There is a gap between the best evidence and clinical status of long-term oral anticoagulant management in patients with atrial fibrillation. In-depth analysis of obstacle factors, formulate countermeasures, and promote the efficient implementation of evidence in clinical practice.

Objective To explore the clinical characteristics of the patients with follicular cysts and menstrual disorders.Methods A total of 178 women with follicular cysts complicated by menstrual disorders were recruited,who were aged 23-53(38.62±6.35)years and came to the Department of Gynecological Endocrinology,Beijing Obstetrics and Gynecology Hospital between August 2022 and July 2024.The participants were divided into three groups according to the age,with 27 women in the age group of 21-30 years(Group 1),77 in the age group of 31-40 years(Group 2),and 74 in the age group of>40 years(Group 3).The age and menstruation of these patients were collected,the body height,weight,follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),progesterone(Po),total testosterone(TT),prolactin(PRL),anti-müllerian hormone(AMH)and thyroid function[blood routine and blood clotting for patients with abnormal uterine bleeding(AUB)]were measured,and the diameter of ovarian cyst and the thickness of endometrium were examined.The clinical characteristics of the patients with follicular cysts complicated by menstrual disorders were described and compared with each other among the three age groups.Results ① Among 178 patients,61(34.3%)patients presented with complaints of cessation of regular menstruation or amenorrhea and 117(65.7%)with complaints of AUB.Out of 178 patients,13(7.3%)patients developed anemia due to AUB,and all the patients were treated with medication.② Follicular cysts disappeared in 1 month for 124(69.7%)patients,disappeared in 2 months for 176(98.9%)patients,and disappeared in 3 months for 178(100%)patients.A total of 177(99.4%)patients had follicular cysts with a diameter less than 5 cm,and only 1(0.6%)patient had follicular cysts with a diameter≥5 cm.③ The overall prevalence of diminished ovarian reserve(DOR)in patients with follicular cysts complicated by menstrual disorders was 82.0%,and the prevalence of DOR was 70.2%for the patients under 40 years old.The prevalence of DOR in three age groups was 37.0%(10/27),81.8%(63/77),and 98.6%(73/74),respectively.The prevalence of DOR gradually increased with age.④ The median AMH values for Group 1,Group 2,and Group 3 were 1.55,0.51,and 0.15 ng/mL,respectively.The FSH level in Group 3 was significantly higher than that in Groups 1 and 2(adjusted P<0.05),while the AMH level was significantly lower than that in Groups 1 and 2(adjusted P<0.05).The AMH level in Group 2 was lower than that in Group 1(adjusted P<0.05).Conclusion Patients with follicular cysts complicated by menstrual disorders are recommended to receive medication treatment,rather than just expecting treatment.The prevalence of DOR in patients with follicular cysts complicated by menstrual disorders is significantly higher than that in normal women,even in women younger than 40 years old.Therefore,it is essential to evaluate the ovarian reserve of these patients while treating menstrual disorders,particularly for young women with fertility needs.

Objective To develop a rehabilitation nursing model for knee osteoarthritis(KOA)of external treatment in traditional Chinese medicine(TCM).Methods Between February and June 2023,a preliminary KOA rehabilitation nursing model was developed through literature search and semi-structured interview method.Two rounds of Delphi consultations were conducted with the selected experts,to establish a rehabilitation nursing model for KOA of TCM external treatment.Results A total of 24 experts from different regions participated in the consultation.The final rehabilitation nursing model of TCM external treatment for KOA included 3 primary indicators,16 secondary indicators and 91 tertiary indicators.The response rates from the two rounds of expert consultation were 96.00%and 100.00%,respectively,and the rates of expert opinion proposal were 58.33%and 8.33%,respectively.The expert authority coefficient were 0.906 and 0.923.The two rounds of expert consultation were 0.137 and 0.236 in Kendall's coefficient of concordance(W),with statistically significant differences(both P<0.001).The importance scores of each item in the second inquiry ranged from 3.75 to 4.88,and the coefficient of variation ranged from 0.07 to 0.30,and the full score ratio ranged from 20.83%to 87.50%.Conclusion The rehabilitation nursing model for KOA of TCM external treatment developed in this study is significant,scientific and feasible.It provides a guidance for medical professionals.

Objective To explore the impact of factors such as economic level,regional differences,and healthcare policies on the medical costs and the clinical treatment behaviors for benign prostatic hyperplasia(BPH)using big data technology.Methods A combination of qualitative and quantitative approaches was employed,including descriptive statistical analysis,central tendency analysis,comparative analysis,and structural analysis to explore regional differences in the treatment of BPH and the underlying causes.Results The mean medical cost per case in the provincial capital city(19 502 yuan)was significantly higher than that in the prefecture-level city(16 526 yuan),with a difference of 2 976 yuan(+18%).Moreover,the cost distribution was more dispersed in the provincial capital([8 370 yuan-26 344 yuan]vs.[9 687 yuan-21 974 yuan]in the prefecture-level city).However,the provincial capital demonstrated better hospitalization efficiency,with a significantly shorter mean length of stay(9.24 days vs 10.21 days,-10.5%).All these differences were statistically significant(P<0.01).Payment methods influenced surgical choices.In the provincial capital,43.99%of patients underwent transurethral resection of the prostate(TURP),with no cases of holmium laser enucleation of the prostate(HOLEP).In contrast,the prefecture-level city reported 22.71%of patients receiving plasmakinetic resection of the prostate(PKRP)and 19.19%undergoing HoLEP.Significant differences were observed in antibiotic utilization patterns.The most commonly used antibiotic in the provincial capital was piperacillin-tazobactam(19.96%),while cefotaxime dominated in the prefecture-level city(21.11%).Notably,ertapenem was frequently used in the provincial capital but rarely in the prefecture-level city,potentially due to cost considerations(P<0.05).Regional preferences were evident in antispasmodic medication;phloroglucinol injection was used in 80%of cases in the prefecture-level city,while anisodamine hydrobromide injection predominated in the provincial capital(P<0.05).For BPH-specific medications,although tamsulosin hydrochloride sustained-release capsules were the primary choice in both regions,the prefecture-level city showed significantly higher usage(80.11%vs 49.17%).Finasteride tablets were more commonly prescribed in the provincial capital(39.03%vs.14.14%,P<0.05).Conclusion Economic levels,healthcare policies,and different hospitals significantly influence clinical decision-making and medical expenses.Hospitals should enhance refined management,while healthcare policy reforms need to advance from multiple perspectives and levels to improve the efficiency and equity of healthcare services.

Objective To explore the efficacy of Da Shuyu Gao(DSG,a formulation developed from the modification of Shuyu Wan and Ziwan Decoction)in treating persistent postural-perceptual dizziness(PPPD)based on the theory of phlegm-qi obstruction.Methods A prospective study was conducted on 120 cases of PPPD patients admitted to the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from January 2022 to July 2023.The patients were randomly divided into a combination group and a control group using a random number table,with 60 patients in each group.The control group received conventional western medicine treatment(Betahistine+Mecobalamin),while the combination group was treated with the decoction of DSG orally in addition to the conventional treatment.The treatment course for the two groups lasted for 2 months.Before and after treatment,the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome score,Somatic Symptom Self-Rating Scale(SSSRS),Hamilton Anxiety Scale(HAMA)score,Hamilton Depression Scale(HAMD)score,Pittsburgh Sleep Quality Index(PSQI)score,and the frequency and duration of dizziness episodes.After two months of treatment,the clinical efficacy of the two groups was compared.Results(1)After 2 months of treatment,the total effective rate of the combination group was 93.33%(56/60),and that of the control group was 78.33%(47/60).The intergroup comparison(tested by chi-square test)showed that the clinical efficacy of the combination group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the scores of TCM symptoms of dizziness,tinnitus,vexation,irritability,dry mouth,and bitterness in the mouth in both groups were improved compared to those before treatment(P＜0.05),and the combination group showed significant improvement compared with the control group(P＜0.01).(3)After treatment,the scores of the cognitive,imaginative,biological,irritability,and inhibitory dimension of SSSRS,as well as the total scores on the SSSRS were significantly improved in both groups compared to those before treatment(P＜0.05),and the combination group showed significant improvement compared with the control group(P＜0.01).(4)After treatment,HAMA,HAMD,and PSQI scores were significantly decreased in both groups compared to those before treatment(P＜0.05),and the decrease in the combination group was superior to that in the control group(P＜0.01).(5)After treatment,the frequency and duration of dizziness episodes were significantly decreased in both groups compared to those before treatment(P＜0.05),and the decrease in the combination group was superior to that in the control group(P＜0.01).Conclusion DSG,formulated based on the theory of phlegm-qi obstruction and clinical practice,demonstrates significant efficacy in treating PPPD.It is effective in decreasing TCM syndrome scores,alleviating somatic symptoms,improving emotional disorders such as anxiety and depression,enhancing sleep quality,and reducing the frequency and duration of dizziness episodes,thereby improving patients'quality of life.The application of DSG will provide a new approach for the clinical treatment of PPPD.
