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.

ObjectiveThis paper aims to systematically reveal the effect difference and mechanisms of Zishenwan against chronic prostatitis （CP） before and after salt-processing of Anemarrhenae rhizoma and Phellodendri chinensis cortex based on an integrated strategy of ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry （UPLC-Q-Orbitrap-MS/MS）， network pharmacology， and serum metabolomics. MethodsZishenwan samples before and after salt-processing of Anemarrhenae rhizoma and Phellodendri chinensis cortex were extracted by alcohol-water dual extraction. The chemical components of each sample were detected by UPLC-Q-Orbitrap-MS/MS， and differential components were screened by multivariate statistical analysis. Network pharmacology analysis was performed based on the identified chemical components of Zishenwan to construct a protein-protein interaction （PPI） network of "component， target， and pathway"， and the core components， targets， and pathways of Zishenwan against CP were screened. Forty-two male Sprague-Dawley （SD） rats were randomly divided into a blank group， a model group， a Qianliekang group （1.54 g·kg^-1）， low- and high-dose raw Zishenwan groups （1.8， 5.4 g·kg^-1）， and low- and high-dose salt-processed Zishenwan groups （1.8， 5.4 g·kg^-1）. The CP rat model was established by intraprostatic injection of carrageenan. After one week of recovery， the rats were administered the corresponding drugs for 21 days， while those in the blank group and model group received the same volume of normal saline. After the experiment， serum and tissue samples were collected to evaluate pharmacodynamic indicators including organ indices， histopathology， and inflammatory factors in serum. Subsequently， untargeted serum metabolomics technology was used to analyze metabolite changes and perform pathway enrichment analysis. The network pharmacology was used to construct a network of "differential metabolite， reaction， enzyme， and gene". ResultsA total of 76 components were identified in raw and salt-processed Zishenwan， and 34 differential components were screened by multivariate statistical analysis. Among them， the contents of 14 components， including berberine， berberrubine， and phellodendrine， increased after salt-processing， while the contents of 20 components， such as neomangiferin， decreased. The 28 active components and 185 potential targets were screened out by network pharmacology. The core components included berberine， phellodendrine， magnoflorine， and jatrorrhizine， and the core targets included signal transducer and activator of transcription 3 （STAT3）， protein kinase B1 （Akt1）， and transcription factor AP-1 （JUN）. These targets were significantly enriched in pro-inflammatory signaling pathways such as phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） and mitogen-activated protein kinase （MAPK）. Compared with the model group， all Zishenwan administration groups showed decreased prostate index， reduced levels of interleukin （IL）-1β， IL-18， and B-cell lymphoma-2 （Bcl-2） in serum （P<0.05， P<0.01）， as well as varying degrees of alleviation in histopathological damage. At the same dose， compared with the raw Zishenwan groups， the salt-processed Zishenwan groups showed lower prostate index， pathological scores， and IL-1β， IL-18， and Bcl-2 levels in serum， but the differences were not statistically significant. Metabolomics reveals that 38 differential metabolites were reversed after salt-processed Zishenwan administration. Both raw and salt-processed Zishenwan regulated pathways such as β-alanine metabolism and tryptophan metabolism. In addition to the common regulated pathways， the salt-processed group specifically regulated pantothenate and coenzyme A biosynthesis， pyrimidine metabolism， and arginine and proline metabolism. The intersecting pathways between network pharmacology and metabolomics were tryptophan metabolism and arginine and proline metabolism， with overlapping targets including monoamine oxidase A （MAOA） and arginase 1 （ARG1）. ConclusionThe increased contents of components such as berberine and phellodendrine in salt-processed Zishenwan may enhance its therapeutic effect on CP by inhibiting the PI3K/Akt and MAPK signaling pathways， along with multi-target regulation of tryptophan， arginine， and pantothenate metabolism pathways to comprehensively regulate inflammatory and immune responses.

ObjectiveTo develop a novel clinical predictive model for metabolic dysfunction-associated fatty liver disease （MAFLD） based on metabolic markers and anthropometric indicators， and to provide a more effective tool for the early screening and intervention of MAFLD. MethodsA retrospective analysis was performed for 2 824 individuals who underwent abdominal color Doppler ultrasound at Health Examination Center of The First Hospital of Lanzhou University from January 1， 2024 to January 1， 2025， and at a ratio of 7∶3， they were randomly divided into training set with 1 976 patients and validation set with 848 patients. Clinical data， serological markers， and abdominal ultrasound results were collected from all patients， and triglyceride-glucose （TyG） index， triglyceride-to-high-density lipoprotein cholesterol （TG/HDL-C） ratio， and anthropometric indicators were calculated. The independent samples t-test was used for comparison of normally distributed or approximately normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The multivariate logistic regression analysis was used to identify independent predictive factors for MAFLD and intermediate- to high-risk MAFLD. Five risk prediction models were established for MAFLD based on the independent influencing factors， and a nomogram was plotted. The receiver operating characteristic （ROC） curve was plotted to assess model performance， and the area under the ROC curve （AUC） was calculated. The calibration curve was used to evaluate the predictive accuracy of the models， and decision curve analysis was used to assess the clinical practicability of the models. These models were then compared with traditional models. ResultsAmong the 1 976 individuals in the training set， 937 （47.42%） were diagnosed with MAFLD， and 423 （21.41%） were diagnosed with intermediate- to high-risk MAFLD； among the 848 individuals in the validation set， 406 （47.88%） were diagnosed with MAFLD. The multivariate logistic regression analysis showed that male sex （odds ratio ［OR］=0.23， 95% confidence interval ［CI］： 0.13 — 0.39， P<0.05）， waist circumference （OR=1.11， 95%CI： 1.06 — 1.17， P<0.05）， alanine aminotransferase （ALT） >40 U/L （OR=2.24， 95%CI： 1.44 — 3.51， P<0.05）， high-density lipoprotein cholesterol （HDL-C） （OR=0.07， 95%CI： 0.04 — 0.15， P<0.05）， TyG index （OR=8.27， 95%CI： 5.09 — 13.44， P<0.05）， TG/HDL-C ratio （OR=0.84， 95%CI： 0.71 — 0.99， P<0.05）， A Body Shape Index （ABSI） （OR=0.45， 95%CI： 0.39 — 0.52， P<0.05）， and body roundness index （BRI） （OR=2.31， 95%CI： 1.50 — 3.55， P<0.05） were independent influencing factors for MAFLD， and male sex （OR=0.17， 95%CI： 0.10 — 0.31， P<0.05）， age （OR=1.09， 95%CI： 1.07 — 1.11， P<0.05）， hemoglobin （OR=0.98， 95%CI： 0.97 — 0.98， P<0.05）， platelet count （OR=0.81， 95%CI： 0.70 — 0.93， P<0.05）， fasting blood glucose （OR=0.80， 95%CI： 0.71 — 0.89， P<0.05）， triglycerides （OR=0.14， 95%CI： 0.07 — 0.29， P<0.05）， TG/HDL-C ratio （OR=0.78， 95%CI： 0.67 — 0.91， P<0.05）， TyG index （OR=5.26， 95%CI： 3.32 — 8.33）， waist circumference （OR=2.50， 95%CI： 1.72 — 3.61， P<0.05）， ABSI （OR=0.58， 95%CI： 0.51 — 0.66， P<0.05）， and BRI （OR=0.01， 95%CI： 0.00 — 0.21， P<0.05） were independent influencing factors for intermediate- to high-risk MAFLD. Among the five models established， model 5 （incorporating sex， ALT elevation， HDL-C， TyG index， TG/HDL-C ratio， waist circumference， and ABSI） had the best performance， with an AUC of 0.917 （95%CI： 0.905 — 0.929） in the training set and 0.911 （95%CI： 0.892 — 0.930） in the validation set. The calibration curve showed that model 5 had good predictive accuracy， and the decision curve analysis confirmed its clinical practicability. ConclusionThe predictive model for MAFLD constructed based on metabolic markers and anthropometric indicators has good discriminatory ability and can be used to assess the risk of MAFLD. In addition， this study shows that waist circumference， TyG index， TG/HDL-C ratio， ABSI， and BRI are independently associated with intermediate- to high-risk MAFLD， but further studies are needed to confirm their value in predicting liver fibrosis progression.

Objective To explore the characteristics and correlation between perivascular spaces (PVS) and diffusion tensor image analysis along perivascular spaces (DTI-ALPS) index in patients with amnestic mild cognitive impairment (aMCI). Methods A retrospective study was conducted on a total of 118 participants, including cognitive normal (CN) healthy controls and aMCI patients, recruited from the Department of Neurology, Zhongshan Hospital, Fudan University from September 2020 to September 2022. All participants underwent structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). An automatic segmentation algorithm was used to quantify PVS metrics in the brain, and DTI-ALPS index was calculated based on DTI. Differences in DTI-ALPS index and PVS metrics between the CN and aMCI groups were compared. Multivariate logistic regression was used to identify independent factors influencing aMCI. Correlation analysis was performed to assess relationships among DTI-ALPS index, PVS metrics, and cognitive scores. Results A total of 80 CN healthy controls and 38 aMCI patients were included. The DTI-ALPS index was significantly lower in the aMCI group compared with the CN group (1.28±0.18 vs 1.37±0.21, P＝0.018), while differences in PVS metrics between groups were not statistically significant. Multivariate logistic regression analysis indicated that DTI-ALPS index was an independent factor affecting aMCI (OR＝0.097, 95%CI 0.011–0.833, P＝0.033). Correlation analysis revealed a positive relationship between DTI-ALPS index and MMSE score (r＝0.210, P＝0.023) as well as PVS length in the centrum semiovale (r＝0.216, P＝0.019). Conclusions The DTI-ALPS index may serve as an imaging biomarker for identifying early cognitive impairment, and patients with aMCI exhibit abnormal DTI-ALPS indices, suggesting that brain glymphatic system dysfunction may occur prior to morphological changes.

Objective:To assess the levels and abnormal rates of trace elements and vitamins among older patients in Beijing Hospital, and to analyze the correlations between these measured indicators.Methods:This study selected 49 older individuals who underwent physical examinations at Beijing Hospital between May 2021 and March 2024.The participants were divided into two age groups: 60-79 years old(23 cases)and 80-100 years old(26 cases). Levels' differences of trace elements and vitamins between the two age groups were analyzed.Pearson correlation analysis was used to investigate the correlations among the tested indicators, and multivariate analysis was conducted using a generalized linear regression model.Results:Among the 49 older individuals, the overall abnormal rate for trace element test results was 8.16%(4 cases), with 2 cases of iron(Fe)deficiency(4.08%)and 2 cases of calcium(Ca)deficiency(4.08%). The overall abnormal rate for vitamin test results was 24.49%(12 cases), which included 5 cases of vitamin B2 deficiency(10.20%), 1 case of vitamin C deficiency(2.04%), and 6 cases of vitamin D deficiency(12.24%). Statistically significant differences were observed between the two age groups in zinc(Zn)and vitamin C levels( t=2.84, 2.83; P=0.007, 0.007). Pearson correlation analysis revealed correlations among 19 pairs of indicators.The top five correlations were between plumbum(Pb)and cadmium(Cd)( r=0.769, P<0.001), Fe and manganese(Mn)( r=0.685, P<0.001), Ca and magnesium(Mg)( r=0.677, P<0.001), vitamin B12 and vitamin C( r=0.455, P=0.001), and vitamin B9 and vitamin D( r=0.422, P=0.003), respectively.The results of the multivariate analysis indicated that, after adjusting for the effects of age group and gender, statistical differences in correlations remained among the remaining trace elements and vitamins, except for those between vitamin B1 and vitamin B12, vitamin B1 and vitamin C, and vitamin A and vitamin D (all P<0.05). Conclusions:The deficiency rates of trace elements and vitamins remain notably high among older patients in our hospital, underscoring the necessity for enhanced nutritional supplementation and regular monitoring of trace element and vitamin levels within this population.Furthermore, a correlation exists between trace elements and vitamins, which offers valuable insights for the diagnosis and treatment of related diseases.

Heat stress(HS)is a critical factor contributing to male infertility,primarily by disrupting the testicular spermatogenic microenvironment,leading to oligospermia,asthenospermia,teratospermia and other male healthcare con-cerns.Sertoli cells are the major components of spermatogenic microenvironment and the blood-testis barrier(BTB),provi-ding structural and nutritional support for spermatogenesis.HS impairs the structure and function of Sertoli cells and the BTB,disrupts the spermatogenesis,and damages other testicular cells and extracellular matrix components.Current re-search predominantly employs surgical or environmental simulation models.A large number of studies have found that natu-ral compounds and traditional Chinese medicines exhibit therapeutic potential through antioxidant,anti-apoptotic,and hor-mone synthesis-regulating mechanisms.Patent and market translation efforts focus on optimizing formulars and developing novel antioxidant molecules.This review systematically summarizes the mechanisms of HS-induced reproductive damage,advances in basic research,and translational progress,aiming to provide a theoretical foundation for clinical diagnosis,treatment,and product development,while enhancing awareness of male reproductive health protection.

The SVA and different serotypes of VSV(VSNJV and VSIV)are susceptible to infect pigs and cause blister injuries to the lips and hoof of pigs.The clinical symptoms of diseases caused by these viruses are very similar,which is easy to cause misdiagnosis.Therefore,a multiplex nano-PCR method was developed for the simultaneous defection of VSV,VSNJV and VSIV.In this stud-y,three pairs of specific primers were designed according to the SVA-P gene,VSNJV-N gene and VSIV-N gene.The optimal annealing temperature and optimal primer concentration were tested,and the reaction system and conditions were optimized.We have developed a novel,rapid and sensitive multiple nano-PCR detection method for simultaneous detection of SVA,VSNJV and VSIV,which was developed by using nano-metal materials.The specific test results showed that the method could specifically amplify the target genes of SVA,VSNJV and VSIV,with no cross-reactivity to PRV,ASFV,PCV2 and PHEV.The sensitivity test results showed that the minimum nucleic acid detection of the method was 10 copies/μL,which sensitivity was great.In addition,the optimal primers showed good reactivity and stability to different batches of enzymes and plasmids.There were 7 among 50 of diseased pig samples were SVA positive by multiple nano-PCR detec-tion method,and 5 out of 50 of diseased pig samples were SVA positive by ordinary single PCR method.Moreover,no VSNJV and VSIV were detected by the two methods.In conclusion,this es-tablished multiple nano-PCR detection method has higher specificity and sensitivity in the detec-tion of SVA,VSNJV and VSIV.And this study could provide technical support for the rapid differ-ential diagnosis,prevention and control of swine viral vesicular diseases in clinical settings.

Objective To investigate the syndromic characteristics of upper airway cough syndrome in children and the rules of tra-ditional Chinese medicine(TCM)prescription and medication.Methods The literature related to the treatment of upper airway cough syndrome in children by TCM in CNKI,Weipu,Wanfang and China Biomedical Literature Service System from the establishment of the database to December 1,2023 was retrieved,extracted the symptoms,signs and prescriptions,and performed data mining using the Chi-nese Medicine Inheritance Computing Platform V3.5.Results Ninety-three articles,25 types of symptoms,119 prescription and 199 flavors of TCM were finally included in the study.The cough was mainly in the morning,and the high-frequency symptoms were nasal congestion,runny nose,and mucus adherence on the posterior wall of the pharynx,and the postnasal drip sensation was present in 25.29％of the children;The main type of symptoms was"wind-heat offending the lungs",followed by"phlegm-heat depleting the lungs"and"wind-phlegm adhering to the lungs",etc.The top five TCM used were Flos magnoliae,Balloonflower root,Siberian cocklebur fruit,Liquorice root and Angelica dahurica;the medicinal properties of these medicines were mainly warm-natured and cold-natured,and the five flavors of these medicines were mainly pungent and bitter;most of the categorized meridians were the lung meridian,and the core medicinal pairs were"Flos magnoliae,Siberian cocklebur fruit""Flos magnoliae,Balloonflower root","Balloonflower root,Liquo-rice root".Three pairs of core drug combinations were obtained by K-Means clustering,all of which were additions to Siberian cocklebur fruit decoction,and their treatment was based on ventilate the lung and inducing resuscitation.Conclusion The diagnosis and treatment of upper airway cough syndrome in children should pay attention to the nasopharyngeal signs,and should pay attention to the passage of the orifices and the pharynx while dredging the wind and clearing the heat and promoting the lung to stop coughing,so as to achieve the effect of the simultaneous treatment of the lung and nose and the lung and throat.
