Objective:To investigate the risk factors for the relapse of autoimmune pancreatitis (AIP) after steroid therapy.Methods:Clinical data of 72 AIP patients treated with steroids in Nanjing Drum Tower Hospital from January 2012 to December 2023 were collected retrospectively. AIP patients were divided into relapse group ( n=25) and non-relapse group ( n=47) based on the presence or absence of their relapse after steroid therapy. Patients' age of onset, gender, history of diabetes mellitus, first clinical manifestations, serum IgG4 and CA19-9 level, imaging features and other organ involvements were recorded. Oral prednisone was used at an initial dose of 0.6 mg·kg -1·d -1, gradually reduced to 5-10 mg/d and then maintained at a low dose. The follow-up period started from steroid initiation to the last follow-up or relapse. The presence of maintenance steroid treatment, time interval between onset and steroid initiation, the presence of significant IgG4 decrease and the presence of persistently enlarged pancreas after therapy were recorded. The cumulative relapse rate curve after steroid therapy was drawn by Kaplan-Meier method. Univariate and multivariate analyses were performed by Cox proportional hazard regression model. The receiver operator characteristic curves (ROC) were plotted and the area under the curve (AUC) was calculated. The Log-Rank test was used to analyze the differences on the relapse between different groups. The subgroup forest plot was drawn to assess the effect of risk factors on the relapse of AIP in different subgroups. Results:The 72 patients with AIP had a median follow-up of 42 (12-127) months. 34.7% (25/72) of patients relapsed after steroid therapy during the follow-up period. The percentages of patients whose first clinical manifestation was abdominal distension or acute pancreatitis, whose interval between onset and steroid initiation was more than 1 year and whose pancreases were persistently enlarged after steroid therapy in the relapse group were higher than those in the non-relapse group, and the differences were all statistically significant (all P value <0.05). The 1-, 3- and 5-year cumulative relapse rate after steroid therapy was 20.8%, 34.1% and 37.8%, respectively. Univariate analysis found that the first clinical manifestations of abdominal distension or acute pancreatitis, interval between onset and steroid initiation more than 1 year, and persistently enlarged pancreas after steroid therapy were all significantly associated with relapse (all P value <0.05). Multivariate analysis found that interval between onset and steroid initiation more than 1 year and persistently enlarged pancreas after steroid therapy were independent risk factors for relapse of AIP [hazard ratio ( HR)=3.606 and 6.515, 95% confidence interval (95% CI) 1.362-9.854 and 2.088-20.326]. Kaplan-Meier survival curves showed that the relapse rate after steroid therapy was higher in AIP patients whose interval between onset and steroid initiation was more than 1 year than in those whose interval was less than 1 year (55.6% versus 27.8%), and the relapse rate in AIP patients with persistently enlarged pancreas after steroid therapy was higher than that in those without it (77.8% versus 28.6%), and the differences were both statistically significant (both P<0.05). Subgroup forest plot showed that persistently enlarged pancreas after steroid therapy was an independent risk factor for relapse of AIP regardless of the presence of a diabetes mellitus history, the first manifestation of abdominal pain, the diffuse or focal type in pancreatic imaging, and the presence of dilated pancreatic duct or not (all P value <0.05). Conclusions:Time interval between onset and steroid initiation more than 1 year and persistently enlarged pancreas after steroid therapy were independent risk factors for the relapse of AIP after steroid therapy.

Objective: To compare the long-term clinical and radiographic outcomes of transforaminal endoscopic lumbar discectomy (TELD) versus microdiscectomy (MD). Methods: The data of 154 patients with lumbar disc herniation (LDH) who underwent TELD (n = 89) or MD (n = 65) were retrospectively analyzed. The patients’ clinical outcomes were evaluated using visual analogue scales for leg and low back pain, the Japanese Orthopaedic Association (JOA) score, and the Oswestry Disability Index (ODI). The evolution of radiographic manifestations was observed during follow-up. Potential risk factors for a poor clinical outcome were investigated. Results: During a mean follow-up of 5.5 years (range, 5–7 years), the recurrence rate was 4.49% in the TELD group and 1.54% in the MD group. All scores significantly improved from preoperatively to postoperatively in both groups (p < 0.01). The improvement in the ODI and JOA scores was significantly greater in the TELD than MD group (p < 0.05). Forty-seven patients (52.8%) in the TELD group and 32 (49.2%) in the MD group had Modic changes before surgery, most of which showed no changes at the last follow-up. The degeneration grades of 292 discs (71.0%) were unchanged at the last follow-up, while 86 (20.9%) showed improvement, mostly at the upper adjacent segment. No significant difference was observed in the intervertebral height index or paraspinal muscle-disc ratio. Conclusion Both TELD and MD provide generally satisfactory long-term clinical outcomes for patients with LDH. TELD can be used as a reliable alternative to MD with less surgical trauma. Modic type II changes, decreased preoperative intervertebral height, and a high body mass index are predictors of a poor prognosis.

Objective The scope of related research on ethical conflicts in the interprofessional collaboration in nursing was reviewed,so as to summarize the obstacles and coping strategies that lead to ethical conflicts in interprofessional collaboration and provide references for promoting nurse engagement in interprofessional collaboration.Methods Based on the methodological framework of the scope review,we systematically searched domestic and foreign databases including the Cochrane Library,CINAHL,Embase,PubMed,Web of Science,CNKI,VIP,Wanfang and SinoMed.The time limit for database retrieval was from the establishment of each database to March 2023.The selected studies were summarized and analyzed.Results Totally 13 articles published between 1991 and 2022 were included.The obstacle factors that lead to ethical conflicts in nurse engagement of interprofessional collaboration can be divided into 3 categories,including personal factors(insufficient professional knowledge,differences in professional values),interprofessional factors(imbalanced power between professions,lack of respect and collaboration between cooperators)and environmental factors(insufficient resources and staffing,high-intensity workload,and high-pressure work environment).At the same time,in view of these 3 aspects,it puts forward some countermeasures,such as enhancing professional knowledge,strengthening interprofessional education,improving understanding and cooperation among medical workers in different wards,providing medical practitioners with a team-based,ethical work environment that facilitates interprofessional collaborations and open dialogues.Conclusion It is of great significance for nurses to get involved in interprofessional collaborations,in order to ensure high-quality nursing services.Further studies are needed for the development of education and the core competency framework construction for interprofessional collaborations in nursing.More attention should be paid to develop the organizational atmosphere at the same time,so as to continuously improve nurse'capabilities in interprofessional collaborations.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

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.

Myocardial fibrosis （MF） is a common pathological manifestation of various heart diseases. Due to the non-renewable nature of myocardial cells， the occurrence of MF represents irreversible damage to the myocardium. Previous studies have suggested that fibroblast-mediated collagen deposition is the main mechanism of MF. Recent studies have found that there is an immune regulation mechanism in the heart itself， and macrophage activation/polarization plays an important role in MF. With the deepening of traditional Chinese medicine research， scholars have found that traditional Chinese medicine can interfere with MF by regulating the renin-angiotensin-aldosterone system （RAAS） system and the inflammatory process， repairing the extracellular matrix， managing oxidative stress， and maintaining the balance of autophagy. This process is closely related to the activation and M1/M2 polarization of macrophages. Throughout the MF process， macrophage activation is beneficial， but excessive activation will be harmful. In the early stage of MF， appropriate M1 macrophage polarization is conducive to activating immunity and removing harmful substances. In the middle and late stages of MF， appropriate M2 macrophage polarization is conducive to remodeling the damaged myocardium. If macrophage activation is excessive/insufficient， or the balance of M1/M2 macrophage polarization is broken， the effect changes from improvement to destruction. Traditional Chinese medicines that regulate the activation/polarization of macrophages have the effects of replenishing Qi and nourishing Yin， as well as regulating Qi and activating blood， but there are also some heat-clearing， dampness-drying， and detoxification products. Therefore， the occurrence of MF may be caused by Qi and Yin deficiency， damp heat accumulation， and Qi stagnation and blood stasis. By summarizing the biological processes involved in macrophage activation/polarization in MF， this paper expounded on the research progress of traditional Chinese medicine in regulating macrophage activation and M1/M2 polarization from different angles to improve MF， so as to provide a reference for the treatment of MF with traditional Chinese medicine.

BACKGROUND:Previous studies have shown the correlation between lumbosacral sagittal plane parameters and natural absorption of lumbar disc herniation.However,the lumbosacral sagittal plane parameters included lumbar lordosis angle,lumbosacral joint angle,sacral inclination angle and many other parameters.The effects of each parameter on the natural absorption of the herniated disc were different.In addition,there are few studies on the reabsorption of a specific segment of intervertebral disc herniation at present,and most of the measured data are obtained from digital radiography or CT,while the correlation between lumbosacral sagittal plane parameters measured from MRI and reabsorption after L5/S1 intervertebral disc herniation is rarely reported. OBJECTIVE:To study the corresponding changes of lumbar sagittal plane parameters after L5/S1 intervertebral disc herniation reabsorption and to screen out the lumbosacral sagittal plane parameters with the most significant changes during intervertebral disc reabsorption. METHODS:Totally 57 patients with lumbar disc herniation who had complete MRI image data were selected and met the diagnostic criteria for lumbar disc herniation and only received non-surgical treatment for reabsorption of L5/S1 protrusion segments.MRI measured the protrusion area of the maximum protrusion plane in the coronal plane,lumbosacral sagittal plane parameters[lumbar curvature index,lumbar lordosis(α),L5/S1 disc angle(β),intervertebral height measurement,lumbosacral joint angle,sacral platform angle,sacral inclination angle,and lower lumbar lordosis angle].Besides,lumbosacral sagittal plane parameters were ranked in the importance of variables by random forest model in R software,and then significant variables were fitted with multiple linear regression.The changes between parameters before and after treatment were analyzed and compared by paired sample t-test. RESULTS AND CONCLUSION:(1)A total of 57 patients with L5/S1 lumbar disc herniation were included in this study,and the symptoms and imaging features of the patients were significantly relieved to a large extent.(2)Before treatment,there were 4 cases of grade 1,29 cases of grade 2 and 24 cases of grade 3 according to the Classification of Michigan State University.After treatment,there were 48 cases of grade 1 and 9 cases of grade 2.(3)The random forest model suggested that intervertebral height,lumbar curve index,sacral inclination angle,and lower lumbar lordosis angle changed significantly in L5/S1 disc herniation reabsorption,and the order of their change significance was lumbar curve index>intervertebral space height>sacral inclination angle>lower lumbar lordosis angle.(4)Lumbar curve index,lumbar lordosis and sacral platform angle increased,with statistical significance(P<0.05).There were no significant differences in disc angle,intervertebral height,lower lumbar lordosis angle,sacral inclination angle or lumbosacral joint angle(P>0.05).(5)Lumbar curvature index was the most significant parameter of the lumbosacral sagittal plane in herniated disc reabsorption.In addition,lumbar curve index,sacral inclination angle,and lower lumbar lordosis angle are commonly used clinically to describe the change of lumbar curvature,suggesting that L5/S1 disc herniation reabsorption is correlated with the change of lumbar curvature.It is indicated that in the treatment of lumbar disc herniation,a clinical cure can be achieved by improving or restoring the disordered lumbar curvature.

Objective:Efficiency is a key factor in the sustainable operation of the medical insurance system.By measuring the current efficiency of the urban employee basic medical insurance system in 31 provinces in China from 2020 to 2021,it discovers possible problems,and provides reference suggestions for improving the efficiency of the system.Methods:Using the super efficiency SBM model based on unexpected output and the Malmquist index to measure the static and dynamic efficiency of employee medical in-surance in 31 provinces in China,and using Tobit regression analysis to analyze its influencing factors.Results:The overall compre-hensive efficiency of the national employee medical insurance operation is 0.826 in 2020 and 0.827 in 2021 respectively.The efficien-cy of employee medical insurance operation in the eastern region is significantly higher than that in the central and westem regions.Over 60％of provinces have inefficient operation of employee medical insurance.The overall total factor productivity of employee medical insurance operation is showing a downward trend,and the decline in technological progress is the main limiting factor.The level of economic development has a significant promotion effect on the efficiency of employee medical insurance operation,and the degree of population aging has a significant inhibitory effect on it.Conclusion:The efficiency of employee medical insurance opera-tion in China still needs to be improved,and there is a significant efficiency gap among different regions.Therefore,investment and attention should be increased in the central and western regions to bridge regional gaps and promote the equity development of medi-cal insurance.Therefore,the reform efforts should be continuously intensified to achieve technological progress.In addition,attention should also be paid to the driving role of economic development in the efficiency of employee medical insurance operation and the for-mulation of positive policies on population aging.
