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.

ObjectiveTo investigate whether modified Taohe Chengqitang （JTCT） treats liver fibrosis by inhibiting hepatic sinusoidal capillarization， and to verify whether its specific mechanism is related to the Homologous genes responsible for the notches along the edges of Drosophila wings（Notch） signaling pathway and endothelial nitric oxide synthase （eNOS） signaling pathway. MethodsFifty C57BL/6 mice were randomized into 5 groups： Control， model （5 mL·kg^-1·3 d^-1）， low-dose JTCT， medium-dose JTCT， and high-dose JTCT （JTCT-L，JTCT-M，JTCT-H）. Except the control group， the other groups were intraperitoneally injected with 20% carbon tetrachloride （CCl₄） olive oil solution every 3 days for 4 weeks to induce liver fibrosis. Meanwhile， JTCT-L， JTCT-M， and JTCT-H groups were administrated with JTCT by gavage at doses of 16.6， 33.3， and 66.6 g·kg^-1·d^-1， respectively， for 4 consecutive weeks （the control and model groups received equal volumes of normal saline by gavage）. Primary liver sinusoidal endothelial cells （LSECs） were isolated from rat livers through in situ perfusion of collagenase， Percoll density gradient centrifugation， and selective removal of Kupffer cells. After verification of cell phenotype， LSECs were used for experiments. For cells at the logarithmic growth phase， the small interfering RNA（siRNA） kit was used to knock down the expression of soluble guanylate cyclase （sGC） through transient transfection. Subsequently， the Notch agonist Jagged-1 was applied. Cell counting kit-8 （CCK-8） was used to examine the cytotoxicity of JTCT on LSECs. Real-time PCR and Western blot were employed to measure the expression of molecules in the Notch and eNOS signaling pathways at mRNA and protein levels， respectively. Intracellular Ca²⁺ was labeled with the fluorescent probe Fluo-4 acetoxymethyl ester（Fluo-4/AM）. ResultsThe animal experiment showed that compared with the control group， the model group exhibited hepatic steatosis， inflammatory cell infiltration， hepatocyte degeneration and necrosis， lobular structural disorder， and fibrous tissue hyperplasia in the mouse liver tissue， significantly elevated serum levels of hydroxyproline （Hyp）， alanine transaminase （ALT）， and aspartate transaminase （AST） （P<0.01）， significantly upregulated expression levels of Notch1， Hes family bHLH transcription factor 1（Hes1）， Cluster of Differentiation 31（CD31）， and von Willebrand factor（vWF） （P<0.01）， and significantly downregulated phosphorylate（p）-eNOS/eNOS ratio and sGC expression （P<0.01）. Compared with the model group， all the JTCT groups showed significantly reduced serum Hyp， ALT， and AST levels （P<0.01）， downregulated expression of Notch1， Hes1， CD31， and vWF （P<0.05， P<0.01）， and upregulated p-eNOS/eNOS ratio and sGC expression （P<0.05， P<0.01） in the liver tissue， with the JTCT-H group showing the most significant changes （P<0.01）. The cell experiment showed that compared with the LSEC-1day group， the LSEC-5day group exhibited significantly increased expression of Notch1， Hes1， CD31， and vWF （P<0.01）， significantly decreased p-eNOS/eNOS ratio and sGC expression （P<0.01）， and elevated intracellular Ca²⁺ concentration （P<0.01）. Compared with the LSEC-5day group， the JTCT group showed decreased expression of Notch1， Hes1， CD31， and vWF （P<0.01）， significantly increased p-eNOS/eNOS ratio （P<0.01）， and significantly reduced intracellular Ca²⁺ concentration （P<0.01）. No significant differences were observed in the expression of Notch1， Hes1， eNOS， p-eNOS， CD31， vWF， sGC， or intracellular Ca²⁺ concentration between the Jagged1 group and the Jagged1+JTCT group. Compared with the LSEC-5day group， the sGC knockout group （sGC-KO） showed significantly increased expression of CD31 and vWF （P<0.01）. There was no significant difference in CD31 or vWF expression between the sGC-KO group and the sGC-KO+JTCT group. ConclusionJTCT inhibits the activation of the Notch signaling pathway and restores the activity of the eNOS signaling pathway to suppress sinusoidal capillarization of LSECs， thereby treating liver fibrosis.

Endometrial cancer (EC) is one of the most common gynecological malignancies, with an increasing incidence rate worldwide. Accurate segmentation of lesion areas in computed tomography (CT) images is a critical step in assisting clinical diagnosis. In this study, we propose a novel deep learning-based segmentation model, termed spatial choice and weight union network (SCWU-Net), which incorporates two newly designed modules: the spatial selection module (SSM) and the combination weight module (CWM). The SSM enhances the model's ability to capture contextual information through deep convolutional blocks, while the CWM, based on joint attention mechanisms, is employed within the skip connections to further boost segmentation performance. By integrating the strengths of both modules into a U-shaped multi-scale architecture, the model achieves precise segmentation of EC lesion regions. Experimental results on a public dataset demonstrate that SCWU-Net achieves a Dice similarity coefficient (DSC) of 82.98%, an intersection over union (IoU) of 78.63%, a precision of 92.36%, and a recall of 84.10%. Its overall performance is significantly outperforming other state-of-the-art models. This study enhances the accuracy of lesion segmentation in EC CT images and holds potential clinical value for the auxiliary diagnosis of endometrial cancer.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To explore the related risk factors contributing to re-fracture after hip surgery in elderly patients.Methods:This retrospective analysis was conducted on the clinical data of 2 415 elderly individuals who underwent surgical treatment for hip fractures and were discharged from Shanghai Sixth People's Hospital between January 2016 and December 2021.Patients were grouped into re-fracture and non-re-fracture cohorts based on whether a second fracture occurred within three years after surgery.Demographics, clinical data, and postoperative functional rehabilitation outcomes of the two groups were collected, and univariate and multivariate logistic regression analyses were applied to identify the independent risk factors for re-fractures after surgery.Results:A total of 2, 000 patients who completed follow-up were included in the final analysis, aged 60~91 years, with a mean age of (75.4±8.2) years.Among them, 855 were male(42.75%), and the postoperative re-fracture incidence was 28.25% (565/2 000). Univariate analysis indicated that advanced age, fracture type at first onset, lower Harris scores, insufficient rehabilitation training, osteoporosis, diabetes, cerebrovascular disorders, visual impairment, and syncope were all significantly associated with re-fracture (all P<0.05), while gender differences were not statistically significant ( P>0.05). Multivariate regression confirmed the following as independent risk factors: age ≥75 years, postoperative Harris score <80, non-standard rehabilitation training, combined osteoporosis, diabetes, cerebrovascular disease, visual impairment, and syncope ( OR、 RR>1). Conclusions:Elderly patients are prone to re-fracture after hip surgery, and its occurrence is closely related to advanced age, inadequate functional rehabilitation, osteoporosis, and multiple internal medical comorbidities.In clinical practice, attention should be paid to standardized postoperative rehabilitation, systematic anti-osteoporotic therapy, and active intervention of comorbidities to reduce the incidence of re-fracture and improve the long-term prognosis of patients.

Objective:To prepare a novel ginseng polypeptide thermosensitive hydrogel,and to investigate its repair effect on heat-induced skin injury in the rats and explore the underlying mechanisms.Methods:Thermosensitive hydrogels were formulated using Pluronic F127 and β-sodium glycerophosphate(β-GP),and their phase transition temperatures,spatial structures,elemental compositions,and water retention capacities were evaluated.The rat models of heat-induced skin injury were established and the model rats were divided into PBS group,Gel group,and ginseng polypeptide gel(GP-Gel)group.After 11 d of treatment,the morphological changes of wound and collagen deposition in the wound of the rats in various groups were observed by HE and Masson staining.Immunohistochemistry was used to detect the expression levels of α-smooth muscle actin(α-SMA),connective tissue growth factor(CTGF),basic fibroblast growth factor(bFGF),proliferating cell nuclear antigen(PCNA),cell proliferation marker Ki67,epidermal growth factor(EGF),CD31,vascular endothelial growth factor(VEGF),P50 and P65 proteins in the skin wound tissue of the rats in various groups.Western blotting method was used to detect the expression levels of Toll-like receptor 4(TLR4)in the skin wound tissue of the rats in various groups.ELISA method was used to measure the levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),interleukin-6(IL-6),interleukin-15(IL-15),and interleukin-10(IL-10)in the serum of the rats in various groups.Results:Compared with PBS and Gel groups,the wound area of the rats in GP-Gel group was reduced(P＜0.01),the expression levels of PCNA,Ki67,EGF,CD31,VEGF,α-SMA,and CTGF proteins in the skin wound tissue were increased(P＜0.05 or P＜0.01),and the expression levels of P65 and TLR4 proteins were decreased(P＜0.01);the level of anti-inflammatory factor IL-10 in serum was increased(P＜0.01),while the levels of pro-inflammatory factors TNF-α,IL-1β,IL-6 and IL-15 were decreased(P＜0.05 or P＜0.01).Conclusion:The ginseng polypeptide thermosensitive hydrogel promotes the repair of heat-induced skin injury by enhancing cell proliferation,collagen synthesis,angiogenesis,and reducing inflammatory responses.

AIM: To observe the influence of different intraocular lens implantation methods on visual quality in patients with cataract.METHODS: Retrospective study. Totally 85 patients(113 eyes)with cataract who received phacoemulsification combined with intraocular lens implantation in the hospital June 2020 to December 2023 were selected. According to the different implanted lenses, they were divided into monofocal group(42 cases, 55 eyes)and bifocal group(43 cases, 58 eyes). The uncorrected near visual acuity(UNVA), uncorrected intermediate visual acuity(UIVA), uncorrected distance visual acuity(UDVA), best corrected near visual acuity(BCNVA), best corrected intermediate visual acuity(BCIVA), best corrected distance visual acuity(BCDVA), contrast sensitivity(CS), objective visual quality, National Eye Institute 25-item Visual Function Questionnaire(NEI-VFQ-25)scores and complications were compared between both groups of patients at 3 mo after surgery.RESULTS:At 3 mo after surgery, the UNVA(LogMAR)of the bifocal group was significantly better than that of the monofocal group(0.24±0.06 vs 0.53±0.13, P<0.001), but there were no statistical differences in UIVA, UDVA, BCNVA, BCIVA and BCDVA between the two groups(all P>0.05). The 18 c/d spatial frequency scotopic CS in the bifocal group at 3 mo after surgery was significantly lower than that in the monofocal group(0.84±0.17 vs 0.92±0.22, P<0.05), while the CS in other frequency was not statistically significant(all P>0.05); the objective scatter index(OSI)was higher in the bifocal group than that in the monofocal group(P<0.05), while OV 20% and OV 9% were lower than those in monofocal group(all P<0.05), but there were no statistically significant differences in modulation transfer function cut off(MTFcut off), Strehl ratio(SR)and OV 100% between the two groups(all P>0.05). The scores of overall visual acuity and near visual activity in the bifocal group at 3 mo after surgery were higher than those in the monofocal group(all P<0.001), but there were no statistical differences in the scores of dimensions of overall health, distance visual activity, peripheral visual acuity, color vision, dependence degree, social function, social role and mental health between the two groups(all P>0.05). Furthermore, there were no statistical significance in the incidence of complications in the two groups(P>0.05).CONCLUSION: Phacoemulsification combined with bifocal intraocular lens implantation can provide more ideal near visual acuity and visual-related quality of life for patients with cataract, but its objective visual quality is worse, The two types of intraocular lenses have their own advantages and disadvantages, and it is still necessary to choose the appropriate intraocular lens according to the actual needs of patients.
