OBJECTIVE:To summarize the development history,research status,hot spots,and future development trends of artificial intelligence technology in the field of bone trauma to provide new insights for future research. METHODS:This study selected relevant literature from the Web of Science core database,covering the period from the inception to August 2023,and retrieved 420 articles related to the application of artificial intelligence,machine learning,and deep learning in the field of bone trauma.After manual screening,202 articles related to this article were exported,and Citespace software was used for visual analysis of cooperation of countries,institutions,cited journals,citation analysis,keyword co-occurrence,and other aspects. RESULTS AND CONCLUSION:(1)The overall number of publications from the 202 selected articles showed an upward trend,indicating significant research potential for future studies.The country with the highest centrality and the highest publication volume was the United States.The University of California(USA)was the most prolific research institution.(2)The top five most commonly used keywords in bone trauma research using artificial intelligence were deep learning,artificial intelligence,bone density,machine learning,and diagnosis.The keyword with the highest centrality was bone density,and the keyword with the highest frequency was deep learning.(3)The top 10 most cited reference papers provided comprehensive insights into the feasibility of applying artificial intelligence techniques to the diagnosis of bone trauma from various perspectives.Among them,eight papers focused on bone and joint injuries and deep convolutional neural networks.One paper discussed the use of deep learning in detecting osteoporosis in CT scans to prevent fragility fractures,while another paper explored the correlation between the application of artificial intelligence in identifying changes in skin texture and the recognition of bone characteristics.(4)In the future,the research hotspots of artificial intelligence will mainly focus on the specific study of fractures caused by bone and joint trauma and osteoporosis.The research trend mainly focuses on improving the performance of artificial intelligence algorithms,using new artificial intelligence technologies to accurately classify and quickly and efficiently diagnose bone injuries,especially for the diagnosis of complex and hidden fractures.By establishing finite element analysis models,more standardized evaluations of bone injuries can be achieved.

Intravitreal injection of anti-vascular endothelial growth factor(VEGF)agents has become the primary treatment for macular edema associated with retinal vascular disease such as diabetic retinopathy and retinal vein occlusion, but there are limitations such as variable treatment efficacy and insufficient durability of therapeutic effects. As the first bispecific antibody applied in ophthalmic treatment, Faricimab achieves favorable outcomes by simultaneously targeting both VEGF-A and angiopoietin-2(Ang-2)pathways. Based on evidence from recent clinical trials and real-world studies, this article reviews the research progress on Faricimab for the treatment of diabetic macular edema(DME), retinal vein occlusion-associated macular edema(RVO-ME)and refractory macular edema compared to the therapeutic effects of other agents. Additionally, based on Faricimab's safety characteristics and future potential, its therapeutic prospects for macular edema associated with retinal vascular diseases are discussed. This review aims to provide evidence-based references for optimizing clinical treatment strategies, thereby contributing to mitigating the risk of vision loss due to macular edema.

Gallbladder polypoid lesions (GPLs) refer to any elevated lesion of the mucosal surface of the gallbladder wall, and the prevalence is estimated to be between 0.9% and 12.1%. GPLs include benign polyps and malignant polyps. Benign polyps are further classified as non-neoplastic polyps and neoplastic polyps. Cholesterol polyps are the most common benign polyps and adenocarcinoma is the main type of malignant polyp. Hepatitis B virus infection, liver function abnormalities, dyslipidemia, and obesity are the main risk factors for GPLs. Studies of biological mechanisms have focused on malignant gallbladder polyps, the development of which is regulated by hormone levels in vivo, gut microbiota, inflammation, oxidative stress, Salmonella typhimurium, and related molecules. Diagnostic modalities include chemical examination and imaging examination, with imaging examination currently being the mainstay. Treatment of patients with GPLs is based on the presence or absence of symptoms, age, size of the polyps, tendency of the polyp to increase, and risk factors for symptomatic malignancy to determine whether surgery should be performed.

Objective:To investigate the efficacy of continuous irrigation and drainage combined with lesion debridement surgery in the treatment of purulent bone and joint infections in children.Methods:A case-control study was conducted to retrospectively analyze the clinical data of 76 children with purulent bone and joint infections who received treatment at Hangzhou Children's Hospital from January 2021 to October 2022. Based on different treatment methods, these children were divided into a control group and an observation group, with 38 cases in each group. The control group received lesion debridement surgery, while the observation group underwent continuous irrigation and drainage combined with lesion debridement surgery. The clinical outcomes of the two groups were compared.Results:The total response rate in the observation group was 97.37% (37/38), which was significantly higher than that in the control group [76.32% (29/38), χ2 = 7.36, P < 0.05]. After treatment, the white blood cell count, erythrocyte sedimentation rate, and percentage of neutrophils in the observation group were (4.32 ± 0.95) × 10 9/L, (14.20 ± 2.50) mm/h, and (52.12 ± 8.45)%, respectively, all of which were significantly lower than those in the control group [(5.68 ± 1.02) × 10 9/L, (22.35 ± 3.35) mm/h, and (66.65 ± 6.20)%, t = 6.01, 12.01, 8.54, all P < 0.05]. The levels of interleukin-6, C-reactive protein, procalcitonin, and tumor necrosis factor-α in the observation group were (5.20 ± 1.02) ng/L, (8.20 ± 1.11) mg/L, (0.80 ± 0.12) μg/L, and (3.20 ± 1.02) ng/L, respectively, which were significantly lower than those in the control group [(8.12 ± 1.10) ng/L, (14.34 ± 2.20) mg/L, (1.12 ± 0.20) μg/L, and (7.50 ± 1.12) ng/L, t = 11.99, 15.36, 8.45, 17.49, all P < 0.05). At 1 week, 1 month, and 3 months after treatment, the Visual Analog Scale scores in the observation group were significantly lower than those in the control group ( t = 3.14, 2.33, 11.36, all P < 0.05). The recurrence rate in the observation group was significantly lower than that in the control group [2.63% (1/38) vs. 21.05% (8/38), χ2= 4.53, P < 0.05). Conclusion:Continuous irrigation and drainage combined with lesion debridement surgery is more effective for treating purulent bone and joint infections in children than lesion debridement surgery alone. This combined therapy can more effectively reduce inflammatory responses, alleviate pain, and lead to a lower recurrence rate.

Cancer-associated thrombosis (CAT) is a common complication and cause of death in cancer patients. Accurately and efficiently identifying high-risk groups for CAT using risk assessment models and implementing targeted early prevention is key. Although numerous CAT risk assessment models currently exist, their predictive capabilities vary across different populations. This article provides a comprehensive review of CAT risk assessment models and their application status, aiming to offer a reference for clinical nursing staff to understand and choose appropriate risk assessment tools.

Objective:To develop the Cancer-associated Thrombosis (CAT) Prevention Knowledge, Attitude and Practice Questionnaire for Nurses, and conduct reliability and validity tests.Methods:This study was a questionnaire development study. Guided by the theory of knowledge, attitude, and practice, an initial CAT Prevention Knowledge, Attitude, and Practice Questionnaire for Nurses was formed through literature review, group discussion, two rounds of expert consultation, and pre-survey. From April to May 2023, convenience sampling was used to select 700 in-service nurses from Chinese Academy of Medical Sciences & Peking Union Medical College as the research subject, and the reliability and validity of the questionnaire were tested.Results:A total of 700 questionnaires were distributed, and 593 valid questionnaires were collected, with a valid response rate of 84.71% (593/700). The final version of the CAT Prevention Knowledge, Attitude, and Practice Questionnaire for Nurses included three dimensions of knowledge, attitude, and practice, with a total of 39 items. The scale-level content validity index ( S- CVI) was 1.000, with an average S- CVI of 0.971 and an item-level CVI (I- CVI) of 0.860 to 1.000. Exploratory factor analysis extracted a total of seven common factors, with a cumulative variance contribution rate of 77.376%. The total Cronbach's α coefficient of the questionnaire was 0.937, and the Cronbach's α coefficients for each dimension were 0.923, 0.987, and 0.979. The half reliability coefficient was 0.984. After two weeks, the reliability coefficients for each dimension of retesting were 0.959, 1.000, and 0.994. Conclusions:The CAT Prevention Knowledge, Attitude, and Practice Questionnaire for Nurses developed in this study has good reliability and validity, and can be used as an evaluation tool for the cognition of clinical nurses in CAT prevention.

Objective:To explore the symptom management experience in young and middle-aged patients with home peritoneal dialysis.Methods:Using the descriptive phenomenological research method and purposive sampling method, 13 young and middle-aged peritoneal dialysis patients were selected for semi-structured interviews, and the interview data was analyzed and sorted out to extract themes.Results:A total of four themes were summarized, including difficulties in symptom management (lack of symptom management knowledge, insufficient symptom perception ability), effect of poor symptom management effectiveness (limited daily life behavior, weakened family roles, obstacles in returning to the workplace, withdrawal of social activities and increased economic burden), polarized symptom management coping strategies (positive and negative responses) and multifaceted symptom management needs (longing for new treatment methods, hoping for disease knowledge popularization and craving for social support in various aspects) .Conclusions:There are many obstacles and needs in the process of symptom self-management of young and middle-aged home peritoneal dialysis patients. It is suggested that medical staff should combine the characteristics and psychology of middle-aged and young peritoneal dialysis patients, implement targeted intervention measures, and improve their symptom management ability.

Objective To explore the effect of fluid shear stress on the expression of glucose regulatory protein 78(GRP78)and C/EBP homologous protein(CHOP)in human umbilical vein endothelial cells(HUVECs).Methods HUVECs were used as experimental cells,and a fluid dynamics simulation experimental system was designed and constructed.Different fluid shear stresses were applied to the experimental cells by controlling the flow rate of the perfusion fluid in the experimental system.According to the fluid shear stress experienced by the experimental cells in the experimental system,they were divided into low shear stress group(group A;0.4Pa),medium shear stress group(group B;0.8 Pa)and high shear stress group(group C;1.2 Pa).Each group of HUVECs consisted of 3 cell slides,and each slide was repeatedly circulated through the perfusion solution of the experimental system for 12 h.Western blotting was used to detect the levels of GRP78 and CHOP proteins,and real-time quantitative reverse transcription polymerase chain reaction was used to determine the levels of GRP78 and CHOP and their messenger RNA(mRNA)in each group.GraphPad Prism 8.0 software was used to statistically analyze the data.Results(1)The relative expression levels of GRP78 protein in groups A,B and C were 1.33±0.46,0.93±0.34,0.64±0.30,respectively,the difference among groups was statistically significant(F=36.17,P＜0.05).The relative expression level of GRP78 protein in group A was higher than that in group B and group C(both P＜0.01),and the relative expression level of GRP78 protein in group B was higher than that in group C(P=0.0013).The relative expression levels of CHOP protein in the three groups were 1.29±0.38 in group A,0.90±0.34 in group B,and 0.59±0.29 in group C,the difference among groups was statistically significant(F=41.27,P＜0.05).The relative expression level of CHOP protein in group A was higher than that in group B and group C(both P＜0.01),and the relative expression level of CHOP protein in group B was higher than that in group C(P=0.0 004).(2)The relative expression levels of GRP78 mRNA in groups A,B,and C were 18.3±3.4,11.3±1.8,5.4±2.2,respectively,the difference among groups was statistically significant(F=189.20,P＜0.05).The relative expression level of GRP78 mRNA in group A was higher than that in group B and group C(both P＜0.01),and the relative expression level of GRP78 mRNA in group B was higher than that in group C(P＜0.01).The relative expression levels of CHOP mRNA in the three groups were 20.4±3.8 in group A,14.2±2.1 in group B,and 7.8±1.3 in group C,the difference among groups was statistically significant(F=171.80,P＜0.05).The relative expression level of CHOP mRNA in group A was higher than that in group B and group C(both P＜0.01),and the relative expression level of CHOP mRNA in group B was higher than that in group C(P＜0.01).Conclusion Low fluid shear stress may increase the protein and mRNA expression levels of GRP78 and CHOP in HUVECs.

Schizophrenia is a common chronic mental disorder.Cognitive dysfunction is one of its core symptoms,which severely affects the social functioning of patients.Currently,antipsychotic medication treatments have poor efficacy in improving cognitive functions.Recent studies have found that metformin can improve cognitive dysfunction in patients with schizophrenia.However,the mechanism of action remains unclear.This review summarizes the therapeutic effects of metformin on cognitive dysfunction in schizophrenia patients such as improving insulin resistance,repairing neuronal damage,regulating neuroimmunity,and combating oxidative stress,thereby providing new insights for the treatment of cognitive dysfunction in schizophrenia.

[Objective]To summarize Professor CHU Haoran's understanding and treatment experience on diarrhea type irritable bowel syndrome(IBS-D).[Methods]Through clinical study with teachers,consulting ancient books and combining modern literature research,summarize the understanding and treatment ideas of Professor CHU for IBS-D,clarify the basic diagnosis and treatment rules of the disease,and provide a clinical medical case as evidence.[Results]Professor CHU believes that disordered movement of Qi in the middle-Jiao is the core pathomechanism of IBS-D.He advocates for the treatment principle of"ascending Qi mechanism,regulating the middle-Jiao,and nourishing vital energy".The acupoint Tianshu(ST25)is considered the focal point,complemented by Zhongwan(CV12),Zhangmen(LR13),Shangjuxu(ST37),Dachangshu(BL25),and Zusanli(ST36)to regulating the middle-Jiao.This is paired with the needling technique of"Dragon and Tiger battle"to assist in facilitating the flow of Qi in the middle-Jiao.A key selection is"Baihui(DU20)-Neiguan(PC6)"to regulate the clear Qi,comb the mind and spirit located in the head,and elevate the overall movement of Qi.Additionally,"Guanyuan(RN4)-Zusanli(ST36)"are used to firm the foundation and cultivate the primal Qi,supplementing the innate vital energy.In a case study,the patient was diagnosed with syndrome differentiation of spleen and stomach deficiency,with concurrent restlessness of the heart spirit and signs of deficient Yang Qi.Professor CHU treated the patient by using the method of raising the clear Qi,managing the middle-Jiao,and nourishing vital energy,supplementing the postnatal to nourish the prenatal while calming the spirit,resulting in significant effects.[Conclusion]In clinical practice,Professor CHU modifies acupoints according to syndrome differentiation.By integrating groups of acupoints,he facilitates the beneficial ascent and descent of Qi within the middle-Jiao,creating a distinctive"regulating the middle and restoring the vital energy"diagnostic and treatment system for IBS-D,which provides a new approach to the clinical treatment of IBS-D.
