Objective This study aims to explore the efficacy and complication rates of the transcranial approach(TCA)and extended endoscopic endonasal approach(EEEA)for the treatment of craniopharyngiomas based on the QST classification,providing a scientific reference for clinical decision-making on surgical approach.Methods A total of 151 patients who underwent craniopharyngioma surgery at our center from January 2018 to December 2023 were enrolled.The patients were categorized into Q-CP(suprasellar type),S-CP(infundibular type),and T-CP(tuberal type)according to the QST classification.Systematic collection and analysis were performed on the outcomes of TCA and EEEA treatments,respectively.The differences in effectiveness between the two approaches were evaluated based on the QST classification.Results The improvement rate of visual symptoms was overall higher in the EEEA group than in the TCA group(59.1%vs.36.5%,P=0.006),and the visual deterioration rate was lower(3.0%vs.14.1%,P=0.006).However,the incidence of cerebrospinal fluid leakage was higher in the EEEA group(15.2%vs.3.5%,χ2=4.986,P=0.026).The incidence of postoperative seizures(8.2%vs.0,P=0.019),brain contusions(10.6%vs.0,P=0.005),and subdural hematoma(9.4%vs.0%,P=0.01)was higher in the TCA group.For patients with Q-CP type,the EEEA group had a higher rate of total tumor resection(92.9%vs.65.2%,P=0.025)and a lower recurrence rate(3.6%vs.21.7%,P=0.047),with shorter hospital stays and lower postoperative costs.The TCA group had higher intraoperative blood loss in this type(300 mL vs.200 mL,Z=-2.261,P=0.024).For S-CP type patients,the EEEA group showed a higher rate of total tumor resection(91.3%vs.74.2%)and a lower recurrence rate(0 vs.12.9%,P=0.031),with lower postoperative hospital costs.In T-CP type,due to the deeper location,EEEA showed limitations in protecting hypothalamic function and the TCA group had a better postoperative hypothalamic function score(P=0.035).Conclusion Based on QST classification,EEEA has advantages in Q-CP and S-CP types and is recommended as the preferred surgical procedure;In the T-CP type,TCA surgery is more helpful in protecting hypothalamic function.

Objective To explore the differences in clinical characteristics of sudden sensorineural hearing loss(SSNHL)between patients with coronavirus disease 2019(COVID-19)and those without-COVID-19.Methods 31 SSNHL patients with COVID-19 who were hospitalized in a department during the COVID-19 epidemic period(from December 2022 to January 2023)were included as the study group,and 12 SSNHL patients without COVID-19 who received treatment during the non-COVID-19 epidemic period(from December 2021 to January 2022)were co-llected as the control group.Two groups of patients received standardized treatment,and their clinical characteristics and prognosis were compared.Clinical characteristics of SSNHL patients with COVID-19 during the COVID-19 epidemic period were analyzed.Results The time interval from patients developed COVID-19 to the onset of SSNHL in the study group was 3-30 days.The time interval from onset to consultation were 3(1,7)days and 5(4,6)days in the study group and the control group,respectively,with no significant difference(P＞0.05).The average age of patients in the study group was(44.16±13.54)years,which was higher than that of the control group(35.23±9.24)years,and the difference was statistically significant(P＜0.05).The hearing at damaged fre-quency of the study group improved by 6.5(0.5,24.5)dB after therapy,which was lower than that of the control group(36.0[27.0,38.0]dB),with statistically significant difference(P＜0.05).There was a negative correlation of the interval of consultation with the average improvement level of hearing at damaged frequency(r=-0.318,P=0.033).The longer the interval,the less the hearing improvement and the worse the therapeutic effect.Corre-lation analysis was further conducted on the time interval from development of COVID-19 to SSNHL onset and the time interval of consultation in patients in the study group,which showed no correlation(r=-0.337,P=0.059).There was no statistically significant difference in the types and degree of SSNHL between two groups of patients(both P＞0.05).After standardized treatment,the rate of ineffective patients in the study group was 56.25％,which was higher than that in the control group(15.38％),and the difference was statistically significant(P＜0.05).Conclusion After adjusting the COVID-19 prevention and control policies,there are more hospitalized COVID-19 patients with SSNHL,with a higher proportion in patients of older age,with poorer efficacy,and inef-fective treatment.The earlier the treatment for SSNHL patients,the better the effect can achieve.COVID-19 may be a potential inducement and/or etiological factor of SSNHL,and further research is needed.

Objective:To investigate the correlation of neutrophil-to-albumin ratio (NAR) and glucose-to-lymphocyte ratio (GLR) with in-hospital death in patients with acute myocardial infarction (AMI).Methods:The clinical data of 2 657 patients with AMI from January 2017 to December 2022 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. Using receiver operating characteristic (ROC) curve to determine the optimal cutoff values of GLR and NAR (6.02 and 0.25) for predicting in-hospital mortality in patients with AMI, the patients were divided into high GLR group (GLR≥6.02, 768 cases) and low GLR group (GLR<6.02, 1 889 cases), high NAR group (NAR≥0.25, 547 cases) and low NAR group (NAR<0.25, 2 110 cases) according the optimal cutoff values. The baseline characteristics and occurrence of in-hospital major adverse cardiovascular events (MACE) were recorded. Multivariate Logistic regression was used to analyze the independent risk factors for in-hospital death in patients with AMI.Results:Among the 2 657 patients with AMI, 265 patients had in-hospital MACE (10.0%), and 50 patients (1.9%) died. The age, proportion of Killip≥ 2 grade, proportion of diabetes, proportion of myocardial infarction, proportion of cerebral infarction history, proportion of ST-elevation myocardial infarction (STEMI), thrombolysis in myocardial infarction clinical trial score (TIMI score), global registry of acute coronary event score (GRACE score), fibrinogen, fasting blood glucose, glycated hemoglobin, high-density lipoprotein cholesterol (HDL-C), cardiac troponin I (cTnI) peak, N-terminal B-type natriuretic peptide (NT-proBNP), hypersensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), NAR, GLR, neutrophil count, left ventricular end-diastolic diameter (LVEDD) in high GLR group were significantly higher than those in low GLR group, the proportion of males, body mass index (BMI), proportion of smoking history, proportion of non-ST elevation myocardial infarction (NSTEMI), albumin, estimated glomerular filtration rate (eGFR), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), lymphocyte count, monocyte count and left ventricular ejection fraction (LVEF) were significantly lower than those in low GLR group, and there were statistical differences ( P<0.01 or <0.05). The proportion of Killip≥2 grade, proportion of STEMI, TIMI score, GRACE score, fibrinogen, fasting blood glucose, TC, LDL-C, cTnI peak, hs-CRP, IL-6, NAR, GLR, white blood cell count, neutrophil count and monocyte count in high NAR group were significantly higher than those in low NAR group, the age, proportion of myocardial infarction history, proportion of NSTEMI, albumin, lymphocyte count, left atrial diameter (LAD) and LVEF were significantly lower than those in low NAR group, and there were statistical differences ( P<0.01 or <0.05). The incidences of in-hospital MACE, death, ventricular fibrillation or pulseless ventricular tachycardia, atrial fibrillation, cardiac arrest and bleeding in high GLR group were significant higher than those in low GLR group: 15.2% (117/768) vs. 7.8% (148/1 889), 4.6% (35/768) vs. 0.8% (15/1 889), 5.3% (41/768) vs. 2.9% (54/1 889), 6.9% (53/768) vs. 4.0% (75/1 889), 4.7% (36/768) vs. 1.4% (26/1 889) and 2.3% (18/768) vs. 0.7% (13/1 889), and there were statistical differences ( P<0.01); there was no statistical difference in the incidence of heart rupture between two groups ( P>0.05). The incidence of in-hospital MACE, death, ventricular fibrillation or pulseless ventricular tachycardia, cardiac arrest, cardiac rupture and bleeding in high NAR group were significantly higher than those in low NAR group: 16.6% (91/547) vs. 8.2% (174/2 110), 5.9% (32/547) vs. 0.9% (18/2 110), 8.0% (44/547) vs. 2.4% (51/2 110), 5.9% (32/547) vs. 1.4% (30/2 110), 1.6% (9/547) vs. 0.4% (9/2 110) and 2.4% (13/547) vs. 0.9% (18/2 110), and there were statistical differences ( P<0.01); there was no statistical difference in the incidence of atrial fibrillation between two groups ( P>0.05). Multivariate Logistic regression analysis result showed that the Killip 3 and 4 grades, high NAR, high GRACE score, high fasting glucose and low LVEF were independent risk factors for in-hospital death in patients with AMI ( OR = 3.827, 4.660, 3.779, 1.020, 1.095 and 0.962; 95% CI 1.158 to 12.649, 1.184 to 18.344, 1.856 to 7.649, 1.009 to 1.032, 1.027 to 1.167 and 0.932 to 0.993; P<0.05 or <0.01). Conclusions:The NAR can independently predict the risk of in-hospital death in patients with AMI.

Allogeneic haemopoietic stem cell transplantation (allo-HSCT)-related nephrotic syndrome is a rare complication, recognized as a clinical manifestation of chronic graft versus host disease (GVHD). T cell dysfunction is thought to play a significant role in the pathogenesis of allo-HSCT-related nephrotic syndrome, but the precise mechanism remains unclear. This paper reported a case of X-linked adrenoleukodystrophy (X-ALD) who had good control of the disease after allo-HSCT, but developed proteinuria and progressed to nephrotic syndrome after immunosuppressive therapy was tapered. Kidney biopsy revealed secondary membranous nephropathy, which responded well to treatment with glucocorticoids and tacrolimus. Limited literature exist on allo-HSCT-related nephrotic syndrome in children. This study provides a comprehensive summary of its mechanism, clinical features, pathology, diagnosis,and treatment, offering valuable insights for diagnosing and managing allo-HSCT-related nephrotic syndrome in pediatric patients.

This article reports a case of membranous nephropathy in an adolescent accompanied by monoclonal IgG1-κ deposition. The 16-year-old female patient was hospitalized for experiencing proteinuria and hematuria for more than 20 days. The patient had a history of mycoplasma infection and acute kidney injury, and renal pathology revealed glomerular membrane lesions accompanied by crescent formation. Electron microscopy showed electron dense deposits in the subepithelial and mesangial regions, and immunofluorescence demonstrated monotypic IgG1-κ deposits in the glomerulus. Bone marrow examination did not find any abnormal plasma cells, nor were there significant abnormalities in serum or urine free light chain κ/λ ratio. The diagnosis was proliferative glomerulonephritis characterized by membranous lesions with monoclonal IgG1-κ deposits. This disease is rare in children and adolescents, and currently there is limited understanding of its mechanism, with limited clinical treatment experience. This article aims to provide clinical insights through case analysis and literature review.

Tacrolimus is an immunosuppressant that was clinically used for organ transplantation in the 1990s. In the early 2000s, tacrolimus began to be used to treat pediatric kidney diseases in China. This article reviews the therapeutic effects, clinical dosages, and treatment methods of tacrolimus in the treatment of steroid-resistant, steroid-dependent, frequently relapsing, different pathological types, and monogenic mutation-related childhood nephrotic syndrome. It explores the clinical guiding role of machine learning in tacrolimus treatment for childhood nephrotic syndrome, aiming to provide references for the clinical research and application of tacrolimus in pediatric kidney diseases.

Objective:To investigate the molecular markers involved in death related to acute myocardial infarction (AMI) and provide new targets for early intervention.Methods:Consecutive patients who hospitalized in department of cardiology, Xuanwu Hospital, Capital Medical University from January 2017 to December 2021 and diagnosed with AMI were enrolled. The clinical factors and markers associated with in-hospital death after AMI were analyzed. In addition, patients diagnosed with AMI hospitalized in department of cardiology, Xuanwu Hospital, Capital Medical University from September 2022 to April 2023 were enrolled. We prospectively analyzed the plasma protein of death related to AMI via Olink Precision Proteomics based on proximity extension assay (PEA) technology.Results:In the retrospective study, 2 325 patients with AMI were analyzed, including 75 patients in the in-hospital death group and 2 250 subjects in the survival group. The overall mortality rate during hospitalization was 3.23% (75/2325). The patients in the death group were older: 72 (64, 80) years vs. 63 (55, 71) years. And Interleukin-6 (IL-6), hypersensitive C-reactive protein (Hs-CRP), leukocyte counts and neutrophil counts were markedly higher in the death group than those in the survival group: 69.0 (26.7, 136.6) ng/L vs. 18.2 (9.4, 36.5) ng/L, 45.7 (28.7, 50.5) mg/L vs. 5.5 (2.0, 17.2) mg/L, 12.0 (9.8, 14.1) ×10 9/L vs. 8.9 (7.2, 11.2) × 10 9/L, 9.8 (7.8, 12.1) ×10 9/L vs. 6.5(4.7, 8.8) ×10 9/L ( P<0.01). In this prospective study, 86 patients with AMI were analyzed. 61 proteins including Insulin-like growth factor-binding protein 1, 2 (IGFBP-1, IGFBP-2), Chitotriosidase-1 (CHIT1), Complement component C1q receptor (CD93) were independently associated with in-hospital death related to AMI ( P<0.05). The differential proteins were mainly enriched in inflammatory response, cell adhesion, cytokine signaling pathway and apoptosis. Moreover, 22 proteins including Urokinase plasminogen activator surface receptor (U-PAR), Trefoil factor 3 (TFF3), Perlecan (PLC), Growth differentiation factor 15 (GDF-15), Junctional adhesion molecule A (JAM-A) were plotted according to a logistic regression model, and the area under the curve (AUC) was more than 0.9, showing the high accuracy in predicting in-hospital death after AMI. Conclusions:Molecular markers of the inflammatory response, cell adhesion, cell growth and apoptosis might be involved in death related to AMI, which provides new targets for early intervention.

Objective To assess the efficacy of combining specialized scenarios with workshop-based teaching in training newly recruited nurses for occupational exposure.Methods This study was conducted with 200 nurses recruited between January 2020 and December 2021 as the control group and 200 nurses from January 2022 to December 2023 as the intervention group.The control group and the intervention group received routine training and workshop-based training,respectively.The efficacy was assessed through theoretical exams,skills assessments,occupational exposure incidence,and training satisfaction,measured u-sing the Simulation Design Scale(SDS).Results The intervention group demonstrated higher scores on theoretical knowledge and operational skills assessments compared to the control group.The occupational exposure were lower in the intervention group.Additionally,the intervention group scored higher on the SDS and reported greater satisfaction with the training(P＜0.05).Conclusion The teaching method integrated with specialized scenarios and workshop-based teaching effectively enhances the theoretical knowledge and operational skills related to occupational exposure among newly recruited nurses.It reduces the inci-dence of occupational exposure,such as needlestick injuries,and improves training outcomes and nurse satisfaction,making it a valuable approach for clinical application.

BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.
