OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Objective:To explore the short-term oncological efficacy of the total prostatic urethra preservation（TPUP）technique in laparoscopic radical prostatectomy and its impact on postoperative urinary continence rate.Methods:The clinical data of 17 prostate cancer patients admitted to Shaoxing People’s Hospital from July 2023 to July 2024 were retrospectively analyzed. The age was（70.5 ± 6.5）years，the body mass index was（23.6 ± 2.5）kg/m 2，and the prostate-specific antigen（PSA）level was（7.845 ± 3.929）ng/ml. The preoperative biopsy pathological Gleason score were 6 in 8 cases，and 7 in 9 cases. All patients underwent laparoscopic radical prostatectomy，and the TPUP technique was used during the operation. The integrity of the preserved urethra was improved by preserving the prostatic surgical capsule closely attached to the corpus spongiosum of the urethra. During the operation，the urethra was completely preserved in 2 cases，nearly completely preserved in 14 cases，and partially preserved in 1 case. The recovery of urinary continence on the day of catheter removal and at 1 and 3 months after the operation was recorded. Recovery of urinary continence was defined as pad within 24 hours. PSA was re - examined at 6 weeks and 3 months after the operation. Results:All 17 operations in this study were successfully completed. The operation time was（143.6 ± 31.6）minutes，and the intraoperative blood loss was 50.0（20.0，50.0）ml. None of the cases was converted to open surgery，and no Clavien - Dindo grade ≥ 2 complications such as blood transfusion or intestinal injury occurred during the peri-operative period. The PSA levels at 6 weeks and 3 months after the operation were 0.054（0.008，0.215）ng/ml and 0.008（0.005，0.037）ng/ml，respectively. The indwelling catheter time after the operation was（13.4 ± 2.1）days. The number of cases with recovered urinary continence on the day of catheter removal and at 1 and 3 months after the operation was 10，15，and 17，respectively.Conclusions:The TPUP technique in laparoscopic radical prostatectomy leads to good recovery of postoperative urinary continence，and there is a slowly PSA decrease in the short term.

BACKGROUND:Some studies have found that ferroptosis of osteoblasts can be an important mechanism to induce the occurrence and development of hormone-induced femoral head necrosis.With the development of Chinese medicine,some scholars have found that some Chinese medicine monomer,Chinese medicine compound and Chinese patent medicine can regulate the ferroptosis of osteoblasts through various pathway mechanisms,and finally play a role in the treatment of steroid-induced avascular necrosis of femoral head. OBJECTIVE:To investigate the relationship between ferroptosis and steroid-induced avascular necrosis of femoral head and the mechanism of Chinese medicine regulating ferroptosis of osteoblasts in the treatment of steroid-induced avascular necrosis of femoral head,so as to provide new ideas for the diagnosis and treatment of steroid-induced avascular necrosis of femoral head. METHODS:With"ferroptosis,steroid-induced avascular necrosis of femoral head,osteoblast,Chinese herbal medicine,glucocorticoid,iron metabolism,reactive oxygen species,glutathione peroxidase"as Chinese search terms,and"ferroptosis,hormonal necrosis of the femoral head,osteoblast,Chinese herbal medicine,glucocorticoid,iron metabolism,ROS,GPX4"as English search terms,the search was conducted on CNKI,PubMed,WanFang,VIP and other databases.The relevant articles on osteoblast ferroptosis and steroid-induced avascular necrosis of femoral head and the regulation of Chinese herbal medicine intervention from the establishment of each database to 2023 were screened.Finally,76 articles were systematically analyzed. RESULTS AND CONCLUSION:(1)Ferroptosis of osteoblasts plays an important role in the pathogenesis of steroid-induced avascular necrosis of femoral head.(2)The occurrence of ferroptosis in osteoblasts is regulated by a variety of mechanisms,such as intracellular iron overload causing ferroptosis.Lipid peroxidation damages cell membrane and causes ferroptosis.Cystine/glutamate reverse transporter induced ferroptosis by influencing glutathione level and glutathione peroxidase 4 activity.Fenton reaction in the cell produces a large number of reactive oxygen species and causes ferroptosis.(3)Chinese medicine monomer icariin,Chinese medicine compound Qinge pills and Chinese patent medicine Bushen Huoxue granules can regulate the occurrence of osteoblast ferroptosis,and help to prevent and treat steroid-induced avascular necrosis of femoral head.(4)The mechanism of ferroptosis in osteoblasts is still unclear.Further investigation on the mechanism of action of both is expected to provide a new choice for clinical treatment of steroid-induced avascular necrosis of femoral head.

Objective To construct an injectable hydrogel(IH)entrapment system of bone marrow mesenchymal stem cells(BM-MSCs)and to explore its effect of promoting articular cartilage repair and underlying mechanism.Methods The primary BM-MSCs of mice were cultured by whole bone marrow adherent method.The differentiation potential was identified by alizarin red(ARS),oil red O(ORO)and Alcian blue(AB)staining,and the expres-sion of CD44,CD90,CD105,CD34 and CD45 on the surface was detected by flow cytometry.BM-MSCs loaded with IH(BM-MSC-IH)was prepared,and the rheological properties of BM-MSC-IH were tested by rheological test.The model of full-thickness injury of knee cartilage in mice was established,and the mice were randomly divided into normal saline group,BM-MSC group and BM-MSC-IH group with 8 in each.The mice were injected with BM-MSC-IH 0.2 mL,cell suspension 0.2 mL and 0.9％NaCl solidion,independently.After 6 and 12 weeks of in-jection,the repair of knee cartilage in mice was observed by safranin-fast green staining,and the expression of typeⅡ collagen in knee joint was examined by immunohistochemical staining microscopy.Results The primary cultured cells showed positive expression of CD44,CD90 and CD105,but negative expression of CD34 and CD45,and had the potential of osteogenic,adipogenic and chondrogenic differentiation.The constructed BM-MSC-IH sys-tem was solid colloid,and the rheological properties were consistent with the basic characteristics of hydrogel.BM-MSC-IH effectively promoted the regeneration of mouse knee cartilage and increase the local expression of typeⅡ collagen.Conclusions Bone marrow-mesenchymal stem cells embedded with injectable hydrogel effectively pro-mote the repair of injured cartilage and the underlying mechanism is potentially promoting the differentiation of chondrocytes and the expression of type Ⅱ collagen.Its effect is better than application of BM-MSCs alone.

BACKGROUND:Although obesity is associated with osteoarthritis,it remains unclear whether visceral adipose tissue has a causal relationship with osteoarthritis. OBJECTIVE:To investigate the causal relationship between visceral adipose tissue and osteoarthritis using two-sample Mendelian randomization methods. METHODS:A total of 221 single nucleotide polymorphisms strongly associated with visceral adipose tissue without linkage disequilibrium were screened from the genome-wide association study (GWAS). Pooled data for osteoarthritis were derived from a large genome-wide association analysis that included up to 826690 subjects (177517 osteoarthritis patients and 649173 controls) from nine different populations. We conducted two-sample Mendelian randomization analyses to assess the causal associations between visceral adipose tissue and early-onset any-site osteoarthritis (before age 45),any-site osteoarthritis,knee osteoarthritis,hip osteoarthritis,knee or hip osteoarthritis,spinal osteoarthritis,thumb osteoarthritis,and finger osteoarthritis. Inverse variance weighting was employed as the primary Mendelian randomization analysis method,with weighted median and MR-Egger methods used for supplementary clarification. RESULTS AND CONCLUSION:Inverse variance weighting results revealed a positive causal effect of visceral adipose tissue on eight types of osteoarthritis:early-onset any-site osteoarthritis[odds ratio (OR)=1.91,95％ confidence interval (CI):1.64-2.24,P=6.04×10-16],any-site osteoarthritis (OR=1.44,95％ CI:1.38-1.49,P=3.65×10-75),knee osteoarthritis (OR=1.87,95％ CI:1.75-2.00,P=1.29×10-79),hip osteoarthritis (OR=1.34,95％ CI:1.24-1.45,P=2.84×10-14),knee or hip osteoarthritis (OR=1.71,95％ CI:1.62-1.80,P=2.97×10-83),spinal osteoarthritis (OR=1.42,95％ CI:1.31-1.54,P=8.89×10-17),thumb osteoarthritis (OR=1.26,95％ CI:1.10-1.44,P=6.21×10-4),and finger osteoarthritis (OR=1.29,95％ CI:1.13-1.49,P=2.68×10-4). Sensitivity analyses showed no heterogeneity,pleiotropy,or outliers in the causal effects of visceral adipose tissue on the eight types of osteoarthritis. These findings indicate that visceral adipose tissue is a risk factor of osteoarthritis,and excessive visceral adipose tissue may increase the risk of osteoarthritis.

Existing epidemiologic and clinical studies have demonstrated that obesity is associated with the risk of a variety of cancers. In recent years, an increasing number of experimental and clinical studies have unraveled the complex relationship between obesity and cancer risk and the underlying mechanisms. Obesity-induced abnormalities in immunity and biochemical metabolism, including chronic inflammation, hormonal disorders, dysregulation of adipokines, and microbial dysbiosis, may be important contributors to cancer development and progression. These contributors play different roles in cancer development and progression at different sites. Lifestyle changes, weight loss medications, and bariatric surgery are key approaches for weight-centered, obesity-related cancer prevention. Treatment of obesity-related inflammation and hormonal or metabolic dysregulation with medications has also shown promise in preventing obesity-related cancers. In this review, we summarize the mechanisms through which obesity affects the risk of cancer at different sites and explore intervention strategies for the prevention of obesity-associated cancers, concluding with unresolved questions and future directions regarding the link between obesity and cancer. The aim is to provide valuable theoretical foundations and insights for the in-depth exploration of the complex relationship between obesity and cancer risk and its clinical applications.

Shift handover is a process of transferring power and responsibility between medical staff,and it is also a basic part of medical activities.Intensive care unit(ICU)is the core area for the treatment of critically ill patients,with complex patient conditions and fine and diverse treatment.If clinical information cannot be shared accurately and in time,it will lead to the delay of the patient's condition,diagnosis and treatment plan.At the same time,the omission of handover information and communication problems can easily lead to safety risks,prolonged hospital stay and increased number of readmissions.Therefore,as one of the important links in ICU diagnosis and treatment and nursing work,accurate,complete and effective handover can ensure the rapid and accurate transmission of patient information and promote the smooth development of diagnosis and treatment and nursing work.This paper reviews the application scope of ICU shift handover model,analyzes the main characteristics,application status and application effects of ICU shift model,and discusses the problems and shortcomings of the existing ICU shift model,in order to provide a reference for further optimizing the quality of ICU shift.PRISMA extension for scoping reviews(PRISMA-ScR)as methodological guidance,we conducted a systematic search across major databases including PubMed,Web of Science,Embase,Cumulative Index to Nursing and Allied Health Literature(CINAHL),and Chinese databases(Wanfang,CNKI,Chinese Medical Association,CBM)using both subject headings and free-text terms).The search time limit was from the establishment of the database to July 18,2024.The preliminary retrieved literature bibliographer was imported into Endnote 20.0 software,and the obtained literature was selected and screened by two researchers.A total of 14 articles were included,of which 10 were from China and 4 were from the United States,and all were published between 2012 and 2022.The analysis showed that the ICU shift mode mainly included improved shift mode,group system shift mode,anti-shift mode,checklist type shift sheet mode and electronic information ICU shift.The shift mode showed diversified characteristics,optimized staffing to a certain extent,standardized the specific content and process of shift,and improved the quality of shift.Significant advances have been made in information delivery and quality of care.However,domestic research is mostly focused on the improvement of the shift mode,which faces the shortcomings of increasing workload,coordination and communication challenges,and the scientification and standardization of tools.Electronic information technology makes up for the shortcomings of information omission in the traditional shift process through the advantages of automatic data collection and information collection,and shows positive results in the process of shift.Future research needs to further explore the basis of not increasing the load of ICU clinical medical staff,ensuring the efficiency of shift and normal work flow.Pay attention to the intelligent,standardized and personalized construction of ICU shift,improve the quality of diagnosis and treatment and nursing,and ensure the safety of patients.

Objective:To explore the effect of chronic intermittent hypoxia(CIH)on learning and memory dysfunc-tion in rats,as well as the expression of high mobility group box-1(HMGB1)and nuclear transcription factor-KB(NF-κB)in the hippocampus region.Methods:The CIH rat model was established,and forty SD rats were randomly divid-ed into four groups:normoxia group,hypoxia for 4 weeks group(CIH4 group),hypoxia for 8 weeks group(CIH8 group),and hypoxia for 12 weeks group(CIH12 group).Morris water maze was used to assess the learning memory ability of rats,and immunohistochemistry and ELISA were used to detect the expression of HMGB1 and NF-κB in the hippocampus of rats.Results:Compared with the normoxia group,the CIH12 and CIH8 groups had longer escape la-tency,the number of crossing the platform and the residence time in the quadrant of the platform were significantly shortened,but there was no significant difference in the CIH4 group.Additionally,there was no significant expression of HMGB1 and NF-κB in the hippocampal region of the normoxia group,but little expression was observed in CIH4 group,and significantly expressed in CIH8 group and CIH12 group,and the expression of CIH12 group was significantly higher than that of CIH8 group.Conclusion:CIH can lead to a decline in learning and memory function in rats,and the longer time of intermittent hypoxia led to the more significant effect on their learning and memory function.In addi-tion,CIH also leads to increased expression levels of HMGB1 and NF-κB in the hippocampus region,and the expres-sion increased more significantly after hypoxia for 12 weeks,comparing to hypoxia for 8 weeks.
