[Objective] To evaluate the feasibility of a novel outpatient infusion model for blinatumomab in two acute lymphoblastic leukemia (ALL) patients, aiming to address challenges of poor treatment tolerance, high healthcare costs, and compromised quality of life, thereby providing clinical insights for broader adoption of this approach. [Methods] Two post-allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients undergoing blinatumomab maintenance therapy were selected to evaluate the efficacy of the outpatient infusion model. Patient selection criteria, nursing protocols, standardized workflows, and advancements in infusion practices were systematically analyzed combined with a review of global developments in this field. [Results] Both patients completed outpatient blinatumomab infusion without severe adverse events, demonstrating preliminary feasibility and safety of this model. The novel approach enhanced treatment convenience, reduced hospitalization costs, and improved quality of life. [Conclusion] Despite the limited sample size, this pilot study highlights the potential of outpatient blinatumomab administration as a viable alternative to traditional inpatient regimens.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Miller-Fisher syndrome （MFS） is a rare neurological disorder and a variant of Guillain-Barré syndrome， with the main manifestations of ophthalmoplegia， ataxia， and absent tendon reflexes， and there are rare case reports of complete eyeball fixation. This article reports a case of MFS with complete eyeball fixation， and the patient had no response to conventional treatment and was improved after treatment with aigamoide α injection. Aigamoide α injection binds to Fc receptors in the body and accelerates the degradation of pathogenic immunoglobulin G （IgG） antibodies in lysosomes， thereby blocking the IgG cycle， and therefore， it is expected to become a potential therapy for GBS.
Ophthalmoplegia

Objective:To construct a representative index system for evaluating pediatric orthopedic nursing quality, providing a basis for hospital pediatric orthopedic nursing quality assessment and monitoring.Methods:From April to July 2023, using the "structure-process-outcome" three-dimensional quality structure model as the theoretical framework, a literature review was conducted, and an item pool was formulated. Through two rounds of Delphi method expert consultations, the hierarchical analysis method was finally employed to determine the indicators and their weights at each level.Results:The effective recovery rates of the questionnaire of the two rounds of expert consultations were 100% (20/20), the authority coefficients of experts were 0.87 and 0.88, the coefficients of variation were 0.00 to 0.27 and 0.00 to 0.24. The Kendell harmony coefficients of the second and third indicators in the two rounds of inquiry were 0.140, 0.166 and 0.192, 0.161(all P<0.05). The final pediatric orthopedic nursing quality evaluation index system included 3 primary indicators, 21 secondary indicators and 83 tertiary indicators. Among the primary indicators, the weight of process quality was the highest at 0.493 4, followed by outcome quality at 0.310 8, and the lowest was structural quality at 0.195 8. In the secondary indicators, "assessment criteria of limb blood circulation" had the highest weight at 0.099 8. Conclusions:The constructed pediatric orthopedic nursing quality evaluation index system covers key aspects and is more operationally feasible. It provides better guidance for nursing interventions and quality control.

Objective:To explore the MR enterography (MRE) features of intestinal Behcet disease (BD) and Crohn disease (CD) in pediatric patients.Methods:This study was a cross-sectional study. The BD patients and CD patients were retrospectively enrolled from Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2019 to October 2022. There were 17 children with intestinal BD, including 6 males and 11 females, aged 5-12 (8.4±2.6) years, and 23 children with CD, including 15 males and 8 females, aged 7-15 (10.2±2.7) years. The MRE images were observed, and the evaluation contents included the diseased intestine (terminal ileum, ileum+ascending colon, ileum+ascending colon+transverse colon, whole colon), the form of intestinal wall thickening (uniform/eccentric thickening), MRI signal (fat suppression T 2WI, DWI), the enhancement mode (uniform/layered enhancement), intestinal stenosis, intestinal dilatation, mesentery comb sign, mesentery fatty fibrosis, lymph node enlargement, and the extraintestinal complication (anal fistula, fluid collection). The comparison of MRE signs between groups was performed using the χ2 test or Fisher exact test. Results:All children were completed MRE examination with good intestinal filling, and no adverse reactions. The significant differences were found in the scope of the diseased bowel, the form of intestinal wall thickening, DWI signal, intestinal dilatation, lymph node enlargement, anal fistula and fluid collection between the intestinal BD and CD patients ( P<0.05), while no significant differences were found in the fat suppression T 2WI signal, enhancement mode of the lesion, intestinal stenosis, mesentery comb sign, and mesentery fatty fibrosis ( P>0.05). Conclusion:MRE is safe and effective, and there are certain significantly different MRE features between children with intestinal BD and CD.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Purpose To explore the application value of computed tomography enterography(CTE)in differentiating active staging of pediatric Crohn disease.Materials and Methods The clinical data of 83 pediatric Crohn disease children performed by CTE examination and conducted with pediatric Crohn disease activity index(PCDAI)from January 2019 to October 2022 were selected.According to their different PCDAI scores,the patients were divided into four groups,which were remission stage(11 cases),mild activity period(47 cases),moderate activity period(14 cases)and severe activity period(11 cases),and the parameters of CTE were analyzed.Then the results associated with CTE and the stages of pediatric Crohn disease activity were analyzed.Results The CTE images of different clinical PCDAI activity stages were manifested in the scope of the diseased intestine(χ2=49.934),the enhancement mode of diseased intestinal wall(χ2=56.561),the degree of intestinal cavity stenosis(χ2=31.932),the degree of intestinal wall thickened(χ2=46.535),lymph node enlargement(χ2=17.330);in which there was a significantly difference(P<0.05),respectively.With the aggravation of PCDAI activity stages,the extent of diseased intestinal canal(more than 50 mm,31 cases,37.3%),the layered reinforcement of diseased intestinal wall(27 cases,32.5%),the luminal stenosis(less than 5 mm,19 cases,22.9%),the thickening of intestinal wall(more than 5.0 mm,54 cases,65.1%)were more common.The proportion of occurrence in the enlargement of lymph nodes(more than 7 mm,16 cases,19.3%)was high,with significant statistical significance(P<0.05).Spearman correlation analysis showed that there was a significant positive correlation between pediatric Crohn disease clinical activity stage(all P<0.01)and the extent of the lesion intestinal canal(r=0.500),the enhancement mode of the lesion intestinal wall(r=0.574),the luminal stenosis(r=0.316),the thickening of intestinal wall(r=0.533).Conclusion With the extent of diseased intestinal canal,the degree of the luminal stenosis,the enhancement mode of diseased intestinal wall and intestinal wall thickened increase,and the clinical stage gradually increase.The above four parameters use as characteristic indicators to reflect the activity stage of pediatric Crohn disease.

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.

Objective:To investigate the preoperative nutritional status of cardiac surgery patients in southwest China, analyze the incidence and characteristics of nutritional risk, and provide basis for establishing a standardized individualized nutritional intervention program for cardiac surgery patients.Methods:A cross-sectional survey was conducted on the nutritional status and intervention status of preoperative patients in cardiac surgery department of 23 general hospitals in Yunnan, Guizhou, Sichuan and Chongqing districts. At 00: 00 on July 7, 2022, the patients aged > 18 years old in cardiac surgery departments of the above hospitals who planned to undergo surgical treatment were enrolled as the survey objects to investigate the nutritional status on July 6, 2022 (the survey date), including basic information (general information, nutrition indicators, etc.), nutrition screening and evaluation (nutrition risk screening and organ support, etc.), nutrition treatment (nutrition supplement methods and prescriptions, etc.) and nutrition awareness of medical staff.Results:The 126 questionnaires were collected, of which 125 were valid (99.2%). ① Basic information: of the 125 patients, 67 patients were male (53.6%) and 58 patients were female (46.4%). The age ranged from 19 years old to 86 years old, with an average of (53.13±14.74) years old. Body mass index (BMI) was (22.21±3.78) kg/m 2. The age and BMI of men were significantly higher than those of women [age (years old): 56.63±13.34 vs. 49.09±15.35, BMI (kg/m 2): 22.74±3.86 vs. 21.59±3.61, both P < 0.05]. Of the 125 patients, 75 had valvular disease and 50 were with non-valvular diseases, which mainly included congenital heart disease [19 cases (15.2%)], aortic dissection [13 cases (10.4%)], coronary heart disease [12 cases (9.6%)], etc. The course of disease was 0.5 hour to 36 years, of which 93 patients (74.4%) were more than 6 months and 32 patients (25.6%) were equal to or less than 6 months. The proportion of female patients with disease duration > 6 months was significantly higher than that of male patients [87.9% (51/58) vs. 62.7% (42/67), P < 0.01]. The basic diseases mainly included hypertension [38 cases (30.4%)], coronary heart disease [12 cases (9.6%)], diabetes [7 cases (5.6%)], chronic obstructive pulmonary disease [COPD, 6 cases (4.8%)], etc. Among 125 patients, total protein (TP) < 60 g/L in 24 cases (19.2%), albumin (Alb) < 40 g/L in 64 cases (51.2%), anemia [male hemoglobin (Hb) < 120 g/L, female Hb < 110 g/L] in 33 cases (26.4%). A total of 60 cases of prealbumin data were collected, of which 23 cases (38.3%) were less than 200 mg/L.② Nutrition screening and assessment: 33.6% of the 125 patients did not undergo routine nutrition screening after admission, including the provincial and municipal tertiary hospitals. Among the 83 patients undergoing nutritional screening, 41 (32.8%) were at nutritional risk. Further analysis of patients with nutritional risk showed that of the 41 patients, 20 were male (48.8%) and 21 were female (51.2%); 27 cases (65.9%) was with valvular diseases and 14 cases (34.1%) was with non-valvular diseases; the course of disease was more than 6 months in 30 cases (73.2%), and ≤ 6 months in 11 cases (26.7%). Statistical comparison of the above 83 patients showed that women, basic disease, long term-valvular disease, anemia, low TP, and low Alb before operation were more prone to innutrition. ③ Nutritional therapy: of the 125 patients, 5 were receiving mechanical ventilation (4.0%) and 2 were using vasoactive drugs (1.6%); there were 5 cases with gastrointestinal dysfunction (4.0%), mainly manifested as abdominal distension, abdominal pain, constipation and diarrhea. One patient was treated with enteral nutrition through gastric tube combined with parenteral nutrition support, 124 patients were fed orally, and an irregular phenomenon of injecting amino acid fat emulsion through peripheral vein in 2 patients. ④ Nutrition awareness of medical staff: 124 (99.2%) of the 125 patients had a nutrition department in their hospital; 71 cases (56.8%) received nutrition education, of which 37 cases (52.1%) were consulted by the nutrition department. Of all the cases, only 38 (30.4%) were consulted by the nutrition department, of which 1 (2.6%) did not receive nutrition education after consultation. Conclusions:At present, the incidence of preoperative malnutrition in patients undergoing cardiac surgery is high in southwest China. The incidence of malnutrition in patients with basic diseases, long term-valvular disease, low TP, low Alb and anemia before operation is higher, and the incidence of malnutrition is hidden in women. The course of disease of women is longer than that of men at the time of treatment, and malnutrition is more likely to occur. The attending physicians should pay attention to the above groups. It is necessary to establish a standardized individualized nutritional intervention program and apply it to actual clinical diagnosis and treatment, so as to ultimately improve the prognosis of patients undergoing cardiac surgery and increase the benefits of patients in treatment.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
