Objective:To analyze the clinical characteristics, RAN-binding protein 2 ( RANBP2) gene variations, and prognosis in Chinese acute necrotizing encephalopathy (ANE) patients. Methods:A retrospective analysis of ANE cases registered in the Peking Union Medical College Hospital Encephalitis Registry System from 2022 to 2024, involving patients from Peking Union Medical College Hospital and other hospitals, was conducted. A descriptive study was performed on the clinical characteristics, treatments and prognosis, cerebrospinal fluid examination results, and imaging findings of these patients based on adjusted ANE diagnostic criteria. Whole-exome sequencing technology was used to detect gene mutations in these patients.Results:A total of 18 ANE cases were included, ranged in age from 2 to 72 [20(5, 43)] years. The male-to-female ratio was 4∶5. All patients were found with precipitating infections including COVID-19, influenza A virus and Mycoplasma pneumoniae infections. All patients presented with fever, with varying degrees of consciousness disturbance observed in 16 cases, and seizures in 10 cases. All patients underwent lumbar puncture, with normal or mildly elevated white cell counts [3(2, 13)×10 6/L] and mildly to moderately elevated protein levels [1.90(0.92, 4.65) g/L]. A total of 6 patients were found with extremely elevated interleukin-6 level [950(164, 2 000) pg/ml] in cerebrospinal fluid. Bilateral symmetric thalamic lesions were typical imaging features of ANE, while involvement of other areas such as cortical and subcortical white matter, brainstem, and cerebellum was also observed. A total of 14 patients performed genetic tests while 4 patients were identified with RANBP2 gene mutations (c.1754C>T in 3 cases, c.1966A>G in 1 case). All patients received immunotherapy, and 7 patients died at discharge while other patients presented with neurological sequelae of varying degrees. Conclusions:ANE is a rare and severe parainfectious encephalopathy that can occur in both children and adults. Clinically, it is characterized by rapidly progressing encephalopathy following systematic infection, with bilateral symmetric thalamic lesions. The detection of RANBP2 gene mutations could help make the diagnosis.

Objective To assess the level of research integrity awareness among clinical nursing personnel in Yunnan Province,analyze the influencing factors,and identify related risks.Methods From June 2025 to July 2025,a research integrity awareness questionnaire was conducted on 697 clinical nursing personnel from a university-affiliated tumor hospital and children's hospital using the Questionnaire Star platform.The survey content included basic information,research integrity awareness status,research integrity construction awareness,and the causes of research misconduct.Data were analyzed using SPSS 27.0.Results The research integrity awareness score of clinical nursing personnel was(47.49±11.06),with an overall awareness rate of 51.48%.Univariate analysis showed statistically significant differences in awareness scores based on nursing categories(t=-2.45),marital status(F=5.557),age(F=2.735),work experience(F=4.775),highest education level(F=13.11),whether serving as a master's supervisor(t=2.693),participation in research projects(t=4.95),whether they had published papers as the first author or corresponding author(t=5.11),and attendance of research integrity training(t=12.48)(P<0.05).Multivariate linear regression analysis indicated that marital status,highest education level,and participation in research integrity training were significant factors influencing clinical nursing personnel's research integrity awareness(P<0.05).The main reason for research misconduct was lack of research integrity awareness The(76.47%),and 92.37%of clinical nursing personnel believed further strengthening of research integrity construction was necessary.Conclusion The research integrity awareness level of clinical nursing personnel needs improvement.Hospitals should enhance research integrity training,improve research integrity management systems,and optimize scientific talent evaluation mechanisms.

Depression is primarily characterized by persistent low mood,emotional disorders,and loss of interest.Somatization disorder is a type of neurotic disorder,primarily featuring recurrent,varied,and non-organic physical discomfort symptoms.In traditional Chinese medicine,depression with somatization disorder can be classified under the category of"depression"and"hysteria"according to its clinical symptoms.This article focuses on the dynamic evolution of the functions of the kidney,spleen,and liver,and explains the core pathogenesis of depression with somatization disorder based on the theory of"cold water,damp earth,and stagnant wood"proposed by HUANG Yuanyu.It explores the causes and related manifestations.Symptoms mainly characterized by cramps and convulsions can be attributed to the liver;symptoms primarily characterized by heaviness,distension,and dull pain accompanied by weakness can be attributed to the spleen;symptoms primarily characterized by stiffness,reluctance to move or inability to move,and reluctance to extend outward can be attributed to the kidney.Liver depression and spleen dampness,as well as wood depression and earth congestion,are treated by strengthening the spleen and soothing the liver,drying dampness and calming wind,and the modified Xiaoyao Powder combined with Yueju Pill is recommended.Spleen dampness and kidney coldness,earth failure and water overflow,are treated by tonifying the spleen and kidney,warming water and transforming dampness,and the modified Jingui Shenqi Pill combined with Linggui Zhugan Decoction is recommended.Kidney coldness and liver hyperactivity,water not nourishing wood,are treated by warming the kidney and enriching essence,replenishing water and nourishing wood,and the modified Dihuang Yinzi is recommended.This article explores the corresponding etiology,pathogenesis,treatment methods,and prescriptions for depression with somatization disorder,with the aim of providing new insights for clinical diagnosis and treatment.

Parkinson's disease is a common neurodegenerative disease with clinical manifestations in-cluding complex motor symptoms and non-motor symptoms,which seriously affects the quality of life in the patients.Multidisciplinary rehabilitation care plays an important role in improving the disease symptoms and delaying the disease progression,which obtains the wide recommendation in the Parkinson's disease treatment guidelines at home and abroad.The international Parkinson Foundation published"Multidisciplinary Rehabili-tation Care in Parkinson's Disease:an International Consensus Statement"in January 2024,which analyses and summarizes the recommendations of guidelines and evidence-based recommendations related to rehabilita-tion care in Parkinson's disease.This paper interprets the 7 aspects of the consensus contents,including the five basic contents of rehabilitation care for Parkinson's disease,commonly used rehabilitation therapy tech-niques,and recommendations related to emerging rehabilitation therapies in order to provide a reference basis for clinically carrying in the high quality of Parkinson's disease rehabilitation care.

Objective:To analyze the impact of cecal ligation and puncture (CLP)-induced sepsis on the proliferation and differentiation of intestinal epithelial cells.Methods:① Animal experiment: sixteen male C57BL/6 mice were divided into sham operation group (Sham group) and CLP-induced sepsis model group (CLP group) by random number table method, with 8 mice in each group. After 5 days of operation, the jejunal tissues were taken for determination of leucine-rich-repeat-containing G-protein-coupled receptor 5 (LGR5) and intestinal alkaline phosphatase (IAP) by polymerase chain reaction (PCR). The translation of LGR5 was detected by Western blotting. The expression of proliferating cell nuclear antigen (Ki67) was analyzed by immunohistochemistry. IAP level was detected by modified calcium cobalt staining and colorimetry. Immunofluorescence staining was used to detect the expression of Paneth cell marker molecule lysozyme 1 (LYZ1) and goblet cell marker molecule mucin 2 (MUC2). ② Cell experiment: IEC6 cells in logarithmic growth stage were divided into blank control group and lipopolysaccharide (LPS) group (LPS 5 μg/mL). Twenty-four hours after treatment, PCR and Western blotting were used to analyze the transcription and translation of LGR5. The proliferation of IEC6 cells were detected by 5-ethynyl-2'-deoxyuridine (EdU) staining. The transcription and translation of IAP were detected by PCR and colorimetric method respectively.Results:① Animal experiment: the immunohistochemical results showed that the positive rate of Ki67 staining in the jejunal tissue of CLP group was lower than that of Sham group [(41.7±2.5)% vs. (48.7±1.4)%, P = 0.01]. PCR and Western blotting results showed that there were no statistical differences in the mRNA and protein expressions of LGR5 in the jejunal tissue between the CLP group and Sham group (Lgr5 mRNA: 0.7±0.1 vs. 1.0±0.2, P = 0.11; LGR5/β-actin: 0.83±0.17 vs. 0.68±0.19, P = 0.24). The mRNA (0.4±0.1 vs. 1.0±0.1, P < 0.01) and protein (U/g: 47.3±6.0 vs. 73.1±15.3, P < 0.01) levels of IAP in the jejunal tissue were lower in CLP group. Immunofluorescence saining analysis showed that the expressions of LYZ1 and MUC2 in the CLP group were lower than those in the Sham group. ②Cell experiment: PCR and Western blotting results showed that there was no significant difference in the expression of LGR5 between the LPS group and the blank control group (Lgr5 mRNA: 0.9±0.1 vs. 1.0±0.2, P = 0.33; LGR5/β-actin: 0.71±0.18 vs. 0.69±0.04, P = 0.81). The proliferation rate of IEC6 cells in the LPS group was lower than that in the blank control group, but there was no significant difference [positivity rate of EdU: (40.5±3.8)% vs. (46.5±3.6)%, P = 0.11]. The mRNA (0.5±0.1 vs. 1.0±0.2, P < 0.01) and protein (U/g: 15.0±4.0 vs. 41.2±10.4, P < 0.01) of IAP in the LPS group were lower than those in the blank control group. Conclusion:CLP-induced sepsis inhibits the proliferation and differentiation of intestinal epithelial cells, impairing the self-renewal ability of intestinal epithelium.

Infantile hemangioma (IH) is the most common benign tumor in infants and young children, with a typical period of proliferation and regression. However, some infantile hemangioma grows rapidly, affects function and even endangers life, and requires active treatment. In recent years, the risk factors for infantile hemangioma have become a hot topic of research. This paper reviews the research status of the risk factors for infantile hemangioma from the aspects of genetic factors and maternal factors, so as to provide help for early clinical diagnosis and treatment.

Objective:To analyze the clinical features, differential diagnosis, treatment and prognosis of complex lymphatic malformations.Methods:The clinical data of patients with complex lymphatic malformation were retrospectively analyzed from April 2010 to April 2022 in the Multidisciplinary Outpatient Department of the Vascular Disease Team of West China Hospital, Sichuan University. All patients were diagnosed with complex lymphatic malformation after consultation with multidisciplinary experts in pediatric surgery, radiology, plastic surgery, pathology, rehabilitation and other departments. The clinical manifestations, blood routine, coagulation function, magnetic resonance imaging and treatment methods of the patients were analyzed. According to the follow-up and disease results, the patients were divided into improvement, stability, progress and death.Results:A total of 18 patients with complex lymphatic malformations were included in the study, including 6 males and 12 females. The age of first diagnosis ranged from 1 month to 29 years old, and the median age was 2.5 years old. Patients were followed up and treated for 0.4 to 12.0 years, with an average follow-up of 3.5 years. Ten patients had pleural and pericardial effusion; 15 patients had visceral involvement which showed multifocal changes in imaging examinations; 9 cases were accompanied by bone destruction, which in Gorham-Stout disease patients broke through the cortex while in generalized lymphatic anomalies it did not; 14 patients had various degrees of coagulation abnormalities, of which 8 patients with severe coagulation dysfunction were all diagnosed as kaposiform lymphangiomatosis. Of the 18 patients, one kaposiform lymphangiomatosis patient died; six patients progressed; eight patients were stable; and three patients improved.Conclusion:The clinical characteristics of patients with complex lymphatic malformations are systemic, diverse and complex. The clinical symptoms of patients with diffuse lymphatic malformation accompanied by involvement of bone and multiple internal organs, chest and abdominal effusion, and coagulation dysfunction should be considered as complex lymphatic malformation. However, due to overlapping clinical characteristics of each subtypes, it is difficult to distinguish patients with complex lymphatic malformation, and the curative effect and prognosis are poor. Precision targeted drugs are the future research direction for the treatment of such diseases.
