Spinal cord injury （SCI） is a prevalent neurological disorder that often results in motor， sensory， cognitive， balance， and walking impairments， and can even lead to pain， significantly affecting the physical and mental health and quality of life of patients. Conventional treatment methods， primarily conducted in hospital settings， tend to be monotonous and lack engagement， leading to low patients’ compliance， motivation and cooperation. In contrast， virtual reality （VR） technology can serve as an effective adjunctive therapeutic approach， immersing patients in simulated virtual environments for functional training in specific contexts and tasks， thereby providing a sense of real experience to achieve assessment and therapeutic outcomes. The interactive and engaging nature of VR technology markedly enhances patients’ interest and motivation in treatment， offering new possibilities for home-based rehabilitation and presenting patients with alternative treatment options. This review systematically introduces the application of VR technology in the treatment of patients with SCI， focusing on its roles in assessing functional impairments， improving motor function， enhancing balance and walking abilities， alleviating pain， and promoting recovery from cognitive and psychological disorders， as well as its impact on other functional impairments and its combined use with other technologies. Furthermore， this article delves into the current advantages and limitations of VR technology， aiming to deepen the understanding of VR among physicians and therapists， promote its widespread clinical application， advance the field of rehabilitation medicine， provide theoretical foundations and directions for future research， and offer new insights and references for clinical practice.

Objective To analyze the correlations between the thoracic electrical impedance tomography(EIT)-derived parameters global inhomogeneity(GI),center of ventilation(COV),regional ventilation delay(RVD),and atelectasis in hospitalized patients,and to explore their effectiveness in evaluating atelectasis.Methods The clinical data of 140 hospitalized patients monitored by thoracic EIT between Sep.2024 and Jan.2025 were retrospectively analyzed.Patients were assigned to 2 groups based on chest computed tomography confirmation of atelectasis within the preceding short-term period during EIT monitoring:non-atelectasis group or atelectasis group.The algorithm software designed with MATLAB was used to acquire GI and COV.RVD was obtained through analysis with the Dr?ger EIT Data Analysis Tool 6.3 software,and patients'general data were concurrently documented.Comparative analysis of EIT-derived parameters between groups was conducted.Multivariate logistic regression analysis was employed to investigate the correlations of GI,COV,and RVD with atelectasis,while receiver operating characteristic curve analysis was performed to assess the efficacy of EIT-derived parameters in evaluating atelectasis.Results A total of 140 patients were enrolled,with 19(13.6%)cases presenting atelectasis.Compared to the non-atelectasis group,the atelectasis group demonstrated significantly higher proportions of male patients and cardiovascular disease and thoracic surgery(non-pulmonary)histories,lower body mass index(BMI),and alongside elevated GI and RVD values with reduced COV(all P＜0.05).Multivariate logistic regression analysis revealed that GI,COV,and RVD maintained independent associations with atelectasis after adjusting for age,gender,BMI,pleural effusion,and emphysema(odds ratio[OR]=1.39,95%confidence interval[CI]1.20-1.67;OR=0.85,95%CI 0.75-0.96;OR=1.22,95%CI 1.09-1.39;all P＜0.05).The area under curve(AUC)values of GI,COV,and RVD for evaluating atelectasis in hospitalized patients were 0.82,0.80,and 0.82,respectively(while RVD demonstrated a higher AUC,its clinical applicability was influenced by respiratory patterns).Conclusion Thoracic EIT-derived parameters GI and COV demonstrate significant correlations with atelectasis and may serve as valuable indicators for evaluating atelectasis in hospitalized patients.

Objective:To investigate the application effect of propofol combined with remifentanil for anesthesia in children undergoing plasma adenoidectomy.Methods:Clinical data of 103 children who underwent plasma adenoidectomy in our hospital from Apr 2023 to Apr 2024 were retrospectively analyzed.Children were divided into two groups according to different anesthesia schemes.Children who received propofol+ketamine anesthesia were enrolled in the control group(n=52)and children who received propofol+remifentanil anesthesia were enrolled in the study group(n=51).Hemodynamic parameters were compared between the two groups at four time points:before anesthesia(T0),immediately after extubation(T1),5 minutes after extubation(T2),and 10 minutes after extubation(T3).The pain scores(CHIPPS)of the two groups were compared at 10,20,and 30 min after extubation.Post-anesthesia evaluation of discomfort(PAED)and incidence of restlessness during recovery in children were compared.The indicators of stress response(cortisol and epinephrine)were measured preoperatively and 1 day postoperatively.Total perioperative adverse events were analyzed.Results:The recovery times for spontaneous breathing,eye-opening,and extubation in the study group were shorter than those in the control group(P＜0.05).The heart rate and mean arterial pressure level in the study group at T1-T3 were lower than those in the control group(P＜0.05).The CHIPPS scores at 10,20,and 30 min after extubation and PAED scores during the recovery period in the study group were lower than those in the control group(P＜0.05).The incidence of restlessness during the recovery period in the study group was lower than that in the control group(P＜0.05).The levels of cortisol and epinephrine in the study group were lower than those in the control group on day 1 after surgery(P＜0.05).There was no significant difference in the overall incidence of adverse reactions between the two groups(P＞0.05).Conclusion:The use of propofol combined with remifentanil in plasma adenoidectomy can effectively shorten the recovery time of anesthesia in children,enhance analgesic effects,reduce blood circulation fluctuations and stress reactions,and reduce the incidence of restlessness,with reliable safety.

Objective To explore the value of dynamic nomogram constructed by multi spiral computed tomography(MSCT)features combined with inflammatory indicators in predicting the status of microvascular invasion(MVI)of hepatocellular carcinoma(HCC)before surgery.Methods The clinical and imaging data of 137 patients with postoperative pathologically confirmed HCC were analyzed retrospectively.According to the status of the MVI,they were divided into positive group(44 cases)and negative group(93 cases).Multivariate logistic regression analysis was used to screen independent risk factors for predicting the MVI status of HCC patients,and a joint prediction model was constructed,which was displayed in the form of a dynamic nomogram.The receiver operating characteristic(ROC)curve,calibration curve and Hosmer-Lemeshow test were used to evaluate the diagnostic efficiency,calibration and goodness of fit of the model,Akaike information criterion(AIC)and Bayesian information criterion(BIC)were used for comparison between the models,and a 5-fold cross-validation and decision curve analysis(DCA)were also used to evaluate the stability and clinical applicability of the model.Results Multivariate logistic regression analysis showed that necrosis and delayed-phase enhancement(DEd),and alkaline phosphatase to lymphocyte ratio(ALR)were independent risk factors for predicting MVI status in HCC patients.The area under the curve(AUC)of the dynamic nomogram was 0.721,with the sensitivity of 0.705 and the specificity of 0.656.The AIC and BIC values were 152.372 and 158.212,respectively.The calibration curve and the Hosmer-Lemeshow test showed that the model had a high degree of calibration and goodness of fit(χ2=2.372,P=0.967),the average AUC of the 5-fold cross-validation was 0.787,and the DCA showed that the nomogram model had a good clinical applicability.Conclusion The dynamic nomogram model constructed by MSCT features combined with inflammatory indicators is feasible to predict the MVI status of HCC patients before surgery,and the dynamic nomogram can directly generate the prediction results of different individuals.

Objective:To explore the risk factors for recurrence of intussusception in children after successful ultrasound-guided saline enema reduction.Methods:The clinical and follow up data of 355 hospitalized children with intussusception at the First Affiliated Hospital of Zhengzhou University from Feb 2018 to Feb 2023 were reviewed.Patients were divided into two groups by recurrence develped and the differences were compared, Data with significant differences were incorporated into multi-factor logistic analysis.Results:The overall recurrence rate was 15.8% (56/355). By univariate variable analysis model, there were statistically significant differences between the two groups in age, previous intussusception history, vomiting, maximum diameter of concentric circles shown by ultrasound, and concurrent bowel organic diseases (lead points) (all P<0.05). In multivariate Logistic regression model, age, previous intussusception history, maximum diameter of concentric circles, and lead points were independent risk factors for recurrent intussusception after saline enema.The optimal cut-off values for age and maximum diameter of concentric circles were 2 years and 33.5 mm, respectively, according to ROC curve analysis. Conclusion:Age older than 2 years, previous intussusception history, maximum diameter of concentric circles longer than 33.5 mm, and lead points are independent risk factors for recurrence after saline enema.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
