Objective:To develop a 5-year mortality risk prediction model for patients with small cell neuroendocrine carcinoma of the cervix(SCNEC).Methods:Based on the Surveillance,Epidemiology,and End Results(SEER)database and R software version 4.3.3,variables were screened via Lasso regression,followed by multivariable logistic regression and stepwise regression to develop a 5-year mortality risk prediction model for SCNEC patients.The Akaike Information Criterion(AIC),C-index,receiver operating characteristic(ROC)curve,Hosmer-Lemeshow test,and calibration curve were employed to evaluate the model.Results:Age,M stage,surgical status,and lymph node metastasis were ultimately selected as variables to construct the 5-year mortality risk prediction model for SCNEC patients.The model demonstrated superior predictive performance compared to FIGO staging(P＜0.01).The Hosmer-Lemeshow test yielded a P-value＞0.05.The C-index values for the training and validation sets were 0.808 and 0.755,respectively,with the areas under the ROC curves of 0.826 and 0.744.The calibration curves of the model fluctuated near the diagonal line,indicating good agreement between predicted and observed outcomes.The decision curve analysis demonstrated significant clinical net benefit.Results showed that higher mortality risk was associated with advanced age,M1 status,lymph node metastasis,and lack of surgical opportunity.Conclusions:The model exhibits good discriminatory power and accuracy,providing significant benefits to patients.Enhanced management should be implemented for patients with advanced age,distant metastasis,lymph node metastasis,or ineligibility for surgery.Lymph node metastasis is an independent risk factor for 5-year mortality in patients with SCNEC.

Objective To develop a platform for reporting medication near miss events and evaluate its application effectiveness,aiming to enhance medication safety of patients.Methods Based on literature review,qualitative interviews,and expert group meetings,a medication near-miss event reporting platform was constructed,including 4 modules:event content filling,event risk grading,event handling,and statistical analysis.50 nurses were conveniently selected from the pediatric ward of a tertiary grade A hospital in Henan Province as the application subjects.The reporting situation and filling duration of medication near miss events,the score of the Medication Near Miss Reporting Disorder Scale,and the incidence of medication near miss events were compared after the application of the platform(from March to August 2023)and before the application(from September 2022 to February 2023).Results The reporting rate of medication near miss events after the application of the platform was higher than that before the application of the platform,and the comparison of the distribution of event nature and occurrence links showed statistically significant differences(P＜0.05).After the application of the platform,the reporting duration of medication near miss events was shorter than that before the application of the platform,and the score of the Medication Near Miss Reporting Disorder Scale was lower than that before the application of the platform.The differences were statistically significant(P＜0.001).There was no statistically significant difference in the incidence of medication near miss events before and after the application of the platform(P=0.241).Conclusion Using this platform can help improve the reporting rate of medication near miss events,reduce the time taken to fill out reports,and minimize reporting barriers for nurses.

Objective To evaluate the clinical efficacy of platelet-rich plasma(PRP)in treat-ment of diabetic foot ulcers(DFU)using a meta-analysis approach.Methods Relevant literature on PRP for treatment of DFU was collected by searching databases including PubMed,Cochrane Library,Embase,Web of Science,NEJM,CNKI,Wanfang Data,VIP Database,and China Biology Medicine disc.Relevant literature on PRP for treatment of DFU was collected.The literature was read,and effect sizes were extracted.The extracted data were then subjected to a meta-analysis using RevMan 5.3 software.Results A total of 6 studies were included in this meta-analysis,involving 440 pa-tients.Among them,there were 208 patients in experimental group(PRP combined with conventional treatment)and 232 patients in control group(conventional treatment,blank control,or placebo treat-ment).The ulcer healing efficacy rate in the experimental group was higher than that in the control group(OR=1.29,95％CI,1.19 to 1.40,P＜0.05).The incidence of adverse reactions in the experimental group was lower than that in the control group(OR=0.33,95％CI,0.12 to 0.93,P=0.94).The healing time(MD=-14.37,95％CI,-23.12 to-5.62,P=0.001),thickness of granulation tissue on the ulcer surface(MD=1.60,95％CI,1.31-1.88,P＜0.000 01),coverage rate of granulation tissue on ulcer surface(MD=6.03,95％CI,3.79 to 8.26,P＜0.05),and level of vascular endothelial growth factor on the ulcer surface(MD=7.62,95％CI,1.57 to 13.67,P=0.01)in the experimental group were all superior to those in the control group.Con-clusion PRP treatment for DFU has the advantages of improving the ulcer healing efficacy rate,shortening the ulcer healing time,promoting the growth of granulation tissue on the ulcer surface,and reducing the incidence of adverse reactions.

Critically ill patients are at high risk for hospital acquired infections, which can significantly increase the mortality rate and treatment costs for these patients. Therefore, in the process of treating the primary disease, strict prevention and control of new hospital infections is an essential component of the treatment for critically ill patients. The treatment of critically ill patients involves multiple steps and requires a concerted effort from various aspects such as theory, management, education, standards, and supervision to achieve effective prevention and control of hospital infections. However, there is currently a lack of unified understanding and standards for hospital infection prevention and control. To address this, in March 2024, a group of experts in critical care medicine, infectious diseases, and hospital infection from China discussed the current situation and issues of hospital infection control in the intensive care unit together. Based on a review of the latest evidence-based medical evidence from both domestic and international sources, 2024 Expert Consensus on Hospital Acquired Infection Control Principles in the Department of Critical Care Medicine was formed, aiming to provide a basis for the development of hospital infection prevention and control strategies in the field of critical care medicine.

Periodontitis is a chronic inflammatory disease marked by a dysregulated immune microenvironment, posing formidable challenges for effective treatment. The disease is characterized by an altered glucose metabolism in macrophages, specifically an increase in aerobic glycolysis, which is linked to heightened inflammatory responses. This suggests that targeting macrophage metabolism could offer a new therapeutic avenue. In this study, we developed an immunometabolic intervention using quercetin (Q) encapsulated in bioadhesive mesoporous polydopamine (Q@MPDA) to treat periodontitis. Our results demonstrated that Q@MPDA could reprogram inflammatory macrophages to an anti-inflammatory phenotype (i.e., from-M1-to-M2 repolarization). In a murine periodontitis model, locally administered Q@MPDA reduced the presence of inflammatory macrophages, and decreased the levels of inflammatory cytokines (IL-1β and TNF-α) and reactive oxygen species (ROS) in the periodontium. Consequently, it alleviated periodontitis symptoms, reduced alveolar bone loss, and promoted tissue repair. Furthermore, our study revealed that Q@MPDA could inhibit the glycolysis of inflammatory macrophages while enhancing oxidative phosphorylation (OXPHOS), facilitating the shift from M1 to M2 macrophage subtype. Our findings suggest that Q@MPDA is a promising treatment for periodontitis via immunometabolic rewiring.

Objective:To investigate the effect of internal fixation of medial support and lateral wall on initial weight-bearing stability of femoral intertrochanteric fracture after reconstruction of intertrochanteric fracture.Methods:Based on the digital model of Sawbones femur, intertrochanteric fracture models with different medial support and lateral wall states were constructed. Combined with various intramedullary and extramedullary fixation methods, the mechanical models after fixation were simplified, and seven mechanical simplified models were obtained. The individual body weight load (70 kg) was simulated by applying concentrated force (700 N) to the end nodes of the femoral head. Through the analysis and calculation of each model in StrucMaster software, the axial force, shear force, bending moment, displacement deformation, and support reaction force of each bar in each mechanical model were obtained, and the results were output through the supporting SMConsole.Results:The median bending moment of model 1 was 11.55(5.57, 18.00) N·m, and the median bending moment was 2.89(2.81, 2.94) rad. The median bending moment of model 2 was 13.72(9.30, 20.05) N·m, and the median bending moment was 2.93(2.77, 3.05) rad. The median bending moment of model 3 was 19.65(10.23, 26.11) N·m, and the median bending moment was 2.93 (2.77, 3.05) rad. The median bending moment of model 4 was 25.95(25.14, 36.70) N·m, and the median bending moment was 4.38(3.16, 5.15) rad. The median bending moment of model 5 was 13.66(7.99, 25.62) N·m, and the median bending moment was 3.50(3.32, 3.56) rad. The median bending moment of model 6 was 24.60(9.33, 29.37) N·m, and the median bending moment was 3.90(3.69, 4.10) rad. The median bending moment of model 7 was 41.14(0.16, 41.30) N·m, and the median bending moment was 5.50(5.50, 7.05) rad. The mechanical properties of model 1 were better than those of the other six models.Conclusion:The simplified mechanical model and its mechanical calculation analysis based on the lever reconstruction balance theory can be used to preliminarily reveal the mechanical characteristics of femoral intertrochanteric fractures after internal fixation. The internal fixation methods of the medial support and lateral wall of femoral intertrochanteric fracture reconstruction can improve the initial stability of the weight bearing after internal fixation of femoral intertrochanteric fractures and have guiding significance for the functional rehabilitation of early postoperative weight bearing.

Objective: To evaluate the effect of venous anastomosis by using microvascular coupler during repair and reconstruction surgery after recection of tumor in oral and maxillofacial area. Methods: 20 patients with oral and maxillofacial tumor were chosen for repair of the defects via free flap. Microvascular coupler was applied to combine venous system,however,traditional methods were used in arterial anastomosis. Results: The average time of venous anastomosis using microvascular coupler was (5. 75 ± 0. 53) min,none of the cases were suffered from thrombosis after surgery. Vascular nerosis resulted from arterial spasm occured in 1 flap,reaching the flap survival rate of 95％(19 /20). Neck bleeding occurred in 1 case after surgery,the reflux of the anastomosed vein went smoothly when the blood clot was cleared,flap healing was unaffected. In another case,the coupler released during the surgery due to thick blood vessel wall as well as hypertension among the anastomotic edge,the vessels were manually sutured. Conclusion: With the appropriate indications, application of microvascular coupler may shorten the operating time,without affecting the effect of vascular anastomosis. The possibility of coupler loosing should be alarmed when bumped into great anastomotic tension or thick wall of the vein.
