Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

ObjectiveTo investigate the therapeutic effect of Astragali Radix-mediated changes in gut microbiota on treating type 2 diabetes (T2DM). MethodsA 12-week randomized, placebo-controlled clinical trial enrolled eighty patients with newly diagnosed type 2 diabetes and poor glycemic control in the Qi deficiency type. All patients received insulin therapy. The observation group (40 cases) was administered with Astragali Radix Granules, while the control group (40 cases) received a placebo. Both treamtents were taken orally twice daily. Changes in gut microbiota were assessed by 16s rDNA sequencing. Serum glucagon-like peptide-1 (GLP-1) levels were measured using enzyme-linked immunosorbent assay (ELISA). Glucose metabolism indicators including fasting blood glucose (FPG), 2-hour postprandial blood glucose (2 h PG),glycated albumin(GA), and glycated hemoglobin (HbA1c) were evaluated. Pancreatic function was evaluated using fasting C-peptide (FCP), 2-hour postprandial C-peptide (2 h CP), and C-peptide area under the curve (AUCcp). Traditional Chinese medicine (TCM) syndrome scores, clinical efficacy, and safety indicators were also observed. ResultsIn terms of glucose metabolism indicators, compared with the baseline, both groups exhibited significantly lower FPG, 2 h PG, GA and HbA1C (P<0.01),while FCP, 2 h CP and AUCcp were significantly higher (P<0.01). Compared with the control group after the treatment, the observation group showed significantly lower FPG, 2 h PG, GA and HbA1C(P<0.05, P<0.01),and significantly higher FCP, 2 h CP and AUCcp (P<0.05, P<0.01), indicating that Astragali Radix can improve glucose metabolism. In terms of the diversity of gut microbiota, no significant differences were detected in the Chao1, Shannon and Simpson indexes of the two groups compared with their respective baselines. However, compared with the post-treatment control group, the observation group demonstrated significant increases in the Chao1, Shannon and Simpson indexes (P<0.05, P<0.01). The β-diversity analysis showed significant separation in gut microbiota composition before and after treatment in both groups, indicating that Astragali Radix can significantly alter the structure and improve the diversity of gut microbiota. At the phylum level, compared with the baseline, both groups showed a significant increase in the relative abundance of Bacteroidota(P<0.01). The relative abundance of the potentially harmful phylum Proteobacteria was significantly lower in the observation Group after treatment (P<0.01). Compared with the post-treatment control group, the observation group had a significantly higher relative abundance of Bacteroidota(P<0.01). No significant difference was found in Firmicutes/Bacteroidota (F/B) ratio between the two groups after treatment, and other phyla showed no significant differences. At the genus level, compared with the baseline, the observation group exhibited a significant increase in Bacteroides (P<0.01) and a significant decrease in Escherichia-Shigella (P<0.01), whereas no significant difference was seen in the control group . Compared with the control group after treatment, the observation group after treatment had a significantly higher relative abundance of Bacteroides (P<0.01). No significant differences were seen in other genera. Linear discriminant analysis (LDA) identified potential characteristics taxa: in the observation group, Bacteroidota at the phylum level and Bacteroides and Dubosiella at the genus level, in the control group, Proteobacteria at the phylum level as well as Barnesiella and Staphylococcus at the genus level. Correlation analysis based on a heatmap revealed that GLP-1 levels were positively correlated with Firmicutes, F/B ratio and Fusobacterium, and negatively correlated with Bacteroidota, Proteobacteria, Bacteroides and Escherichia-Shigella. In terms of clinical efficacy, compared with the control group, the total effective rate of the observation group was significantly higher (P<0.05). Compared with the baseline, the scores for shortness of breath, fatigue, weakness, spontaneous sweating and reluctance to speak significantly decreased in both groups (P<0.01). Compared with the control group after treatment, the score for weakness was significantly lower in the observation group (P<0.01),indicating that Astragali Radix could improve clinical symptoms and alleviate weakness symptoms. In terms of safety, compared with the baseline, alanine aminotransferase (ALT) levels significantly decreased in both groups (P<0.05,P<0.01),indicating that Astragali Radix did not induce any significant abnormalities in liver and kidney functions. ConclusionAstragali Radix demonstrates the potential to significantly improve the gut microbiota environment in patients of newly diagnosed type 2 diabetes with Qi deficiency. The therapeutic effect may contribute to glycemic control, possibly mediated by an elevation in GLP-1 level. These findings may support its further clinical investigations and potential applications.
4.Research advances in iron metabolism disorder and intracranial atherosclerotic cerebral infarction
Journal of Apoplexy and Nervous Diseases 2026;43(2):185-192
Intracranial atherosclerosis (ICAS) is an important etiology of ischemic stroke and has a complex pathogenesis. Iron is an essential trace element for maintaining normal physiological functions of the human body, and the regulation of iron homeostasis is of great significance for ensuring proper physiological activities. Studies in recent years have shown that iron metabolism disorder plays a pivotal role in the development and progression of intracranial atherosclerotic cerebral infarction, involving various pathological processes such as inflammatory response, cell death, lipid metabolism, and blood-brain barrier dysfunction. This article systematically elaborates on the mechanisms through which iron overload promotes ICAS, including oxidative stress, inflammatory response, and lipid peroxidation,with a focus on the key role of related molecular mechanisms (including glutathione depletion, inhibition of GPX4 activity, and lipid peroxide accumulation)in intracranial atherosclerotic cerebral infarction, in order to provide new ideas for the prevention and treatment of intracranial atherosclerotic disease.

OBJECTIVE:
To carry out genetic testing and clinical phenotypic characterization on a four-generation Chinese pedigree affected with Stickler syndrome type I and explore its genotype-phenotype correlation.
METHODS:
A child presented at the Second Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine in February 2023 for micrognathia, glossoptosis and cleft palate and his family members were selected as the study subjects. Clinical data were collected from the affected members, and peripheral blood samples were obtained from 17 participants (including 4 patients and 13 asymptomatic individuals). Whole exome sequencing (WES) was carried out. Candidate variant was verified by Sanger sequencing. Genotype-phenotype correlation was analyzed by integrating the sequencing data with evidence from existing literature. This study has bee granted by the Ethics Committee of Guangdong Provincial Hospital of Traditional Chinese Medicine and Guangzhou Women and Children's Medical Center (Ethics No.: 2022-406B00).
RESULTS:
The four-generation pedigree has comprised 19 members. In addition to the proband, 5 affected individuals had manifested with high myopia, congenital cataracts, and progressive vision loss. Two deceased members reportedly exhibited similar ocular manifestations. Among the four living patients, two had developed retinal detachment, while two others presented with chronic joint pain onset between 35 ~ 40 years of age. One patient required hip replacement surgery at age 42 secondary to femoral head necrosis. The proband, the youngest affected member, exhibited characteristic phenotypes including congenital micrognathia and cleft palate, consistent with Pierre-Robin syndrome. Genetic analysis revealed a heterozygous nonsense mutation in COL2A1 (NM_001844.5: c.2668C>T; p.Gln890Ter) segregating with the disease in all four symptomatic patients. This variant was absent in asymptomatic family members and unaffected controls. While the mutation is listed in ClinVar, no clinical case report has associated it with this phenotypic spectrum. It was not recorded in population databases (gnomAD v4.1.0, 1000 Genomes Project, or ExAC), supporting its potential pathogenicity.
CONCLUSION
This study has diagnosed a four-generation Chinese pedigree with Stickler syndrome type I attributed to the pathogenic COL2A1 variant c.2668C>T (p.Gln890Ter), which is a rare nonsense mutation associated with ocular predominance and variable skeletal involvement. Notably, this family exhibited marked clinical heterogeneity despite sharing the identical genotype, which highlighted the challenges in phenotype-genotype correlation. The autosomal dominant transmission pattern observed in this pedigree has provided critical insights into COL2A1-related collagenopathies and underscored the necessity of ultrasonographic monitoring for ocular anomalies during prenatal diagnosis. Above findings have advanced our understanding of the pleiotropic effects in type Ⅱ collagen disorders and laid the foundation for precision-based genetic counseling, enabling targeted cascade screening and implementation of tertiary prevention strategies against congenital disabilities for high-risk families.

Objective:To develop and validate machine learning-based radiomics models using preoperative CT images for individualized prediction of mitotic index (MI) in patients with gastrointestinal stromal tumors (GIST).Methods:The study was a case-control study. The data of 348 GIST patients confirmed by pathology were retrospectively collected from two independent medical centers: the Affiliated Hospital of Qingdao University (center 1) and Shandong Provincial Hospital Affiliated to Shandong First Medical University (center 2), covering the period from January 2013 to June 2018. Patients from center 1 were divided into a training cohort (176 cases) and an internal validation cohort (75 cases) at a ratio of 7∶3 using random sampling. Patients from center 2 served as an independent external validation cohort (97 cases). The primary endpoint was MI, categorized into high MI (145 cases) and low MI (203 cases) groups. Radiomic features were extracted from the portal venous phase images of preoperative contrast-enhanced CT scans. Five machine learning algorithms, including logistic regression, support vector machine, random forest, decision tree, and extreme gradient boosting (XGBoost),were employed to construct MI prediction models. The optimal model was identified using receiver operating characteristic curves. An individualized prediction model was developed by integrating the the optimal machine learning model combined with selected independent clinical factors, and the importance of features was visualized using Shapley Additive Explanation (SHAP) analysis. Patients were followed up, and Kaplan-Meier curves along with log-rank tests were used to evaluate recurrence-free survival (RFS) differences between the predicted high MI and low MI groups.Results:Among the five constructed machine learning models, the XGBoost model demonstrated the best predictive performance, with area under the curve (AUC) of 0.809 (95% CI 0.738-0.872), 0.693 (95% CI 0.571-0.809), and 0.718 (95% CI 0.605-0.822) in the training cohort, internal validation cohort, and external validation cohort, respectively. An individualized prediction model combining the XGBoost model with independent clinical factors (tumor location and tumor size) was developed. The model achieved AUC of 0.843 (95% CI 0.785-0.899), 0.791 (95% CI 0.680-0.894), and 0.777 (95% CI 0.678-0.861) in the training cohort, internal validation cohort, and external validation cohort, respectively. SHAP analysis indicated that radiomic features had the highest predictive impact. In both the training cohort and internal validation cohort, the RFS of patients predicted to be in the high MI group was lower than that of the low MI group, with statistically significant differences ( χ2=14.58, 9.52, both P<0.001). However, there was no statistically significant difference in RFS in the external validation set ( χ2=6.18, P=0.080). Conclusions:The optimal XGBoost model based on radiomic features extracted from preoperative portal venous phase CT images, when combined with clinical factors, can effectively predict the MI of GIST patients.

Objective:To evaluate the value of ultrasound radiomics combined with machine learning for early diagnosis of seronegative Hashimoto’s thyroiditis (SN-HT) .Methods:This retrospective study included 164 patients from Liaoning Provincial People’s Hospital , Lixin County People’s Hospital, Linghai Dalinghe Hospital, Fengcheng Phoenix Hospital, who underwent thyroidectomy for solitary nodules with normal thyroid function between Nov. 2016 and Jan. 2024. Postoperative pathology confirmed Hashimoto’s thyroiditis (HT) in some cases, who were further categorized into antibody-positive and antibody-negative groups based on serum antibody status. Patients without Hashimoto’s thyroiditis served as the control group. A total of 298 ultrasound images were analyzed. Radiomics features were extracted from hypoechoic non-nodular areas within 0.5 cm surrounding the tumor. Two senior pathologists and two senior ultrasound physicians independently assessed lymphocytic infiltration, eosinophilic changes of follicular epithelium, and the proportion of hypoechoic areas in pathology and ultrasound images, respectively. A machine learning model, CCH-NET, was developed using linear regression and t-distributed stochastic neighbor embedding (t-SNE) techniques. The dataset was divided into a training set (80%) and a validation set (20%) to compare the diagnostic accuracy of CCH-NET with that of senior ultrasound physicians. Results:In internal validation, CCH-NET achieved a diagnostic accuracy of 88.89% for both antibody-positive and antibody-negative groups, significantly higher than the 66.67% accuracy of senior ultrasound physicians ( P<0.01). In external validation, CCH-NET achieved 75.00% and 66.67% accuracy for the two groups, compared to 50.00% by senior ultrasound physicians. For the control group, both methods achieved 93.33% accuracy. The AUC of CCH-NET was 0.848, outperforming senior ultrasound physicians (0.681) ,demonstrating superior diagnostic performance. Conclusion:The radiomics-based CCH-NET model, using non-nodular hypoechoic areas as a specific indicator, can accurately identify early SN-HT in euthyroid patients. It significantly outperforms senior ultrasound physicians, improving diagnostic accuracy and reducing missed diagnoses.
