BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Objective:To establish normal reference value ranges for dynamic balance function parameters in healthy Chinese adults aged 20-69 years. Methods:A total of 100 healthy subjects were selected and evenly divided into five age groups: 20-29, 30-39, 40-49, 50-59, and 60-69 years, with equal gender distribution in each group. Balance function was assessed using the EquiTest system （NeuroCom）, with following tests performed Sensory Organization Test （SOT）, Motor Control Test （MCT）, Adaptation Test （ADT）, and Limits of Stability （LOS） test. All parameters were statistically analyzed and expressed as ±S. Results:The normal reference ranges for SOT, MCT, ADT, and LOS parameters were established for each age group. Multiple balance function parameters demonstrated a gradual decline with advancing age, with more pronounced deterioration observed after the age of 60. Specific findings included decreased vestibular ratio and reduced visual preference in SOT, as well as prolonged reaction time, impaired directional control, and reduced maximum excursion in the backward direction during LOS testing. Conclusion:This study is the first to establish age-specific reference ranges for dynamic balance function parameters in a healthy Chinese population aged 20-69 years, providing localized and objective criteria for the assessment of balance function and supporting clinical diagnosis of balance-related disorders in China.

Metformin has been demonstrated to attenuate hyperglycaemia by modulating the gut microbiota. However, the mechanisms through which the microbiome mediates metformin monotherapy failure (MMF) are unclear. Herein, in a prospective clinical cohort study of newly diagnosed type 2 diabetes mellitus (T2DM) patients treated with metformin monotherapy, metagenomic sequencing of faecal samples revealed that Phocaeicola vulgatus abundance was approximately 12 times higher in nonresponders than in responders. P. vulgatus rapidly hydrolysed taurine-conjugated bile acids, leading to ceramide accumulation and reversing the improvements in glucose intolerance conferred by metformin in high-fat diet-fed mice. Interestingly, C22:0 ceramide bound to mitochondrial fission factor to induce mitochondrial fragmentation and impair hepatic oxidative phosphorylation in P. vulgatus-colonized hyperglycaemic mice, which could be exacerbated by metformin. This work suggests that metformin may be unsuitable for P. vulgatus-rich T2DM patients and that clinicians should be aware of metformin toxicity to mitochondria. Suppressing P. vulgatus growth with cefaclor or improving mitochondrial function using adenosylcobalamin may represent simple, safe, effective therapeutic strategies for addressing MMF.

OBJECTIVES: To explore the expression profile of circular RNAs (circRNAs) and their potential roles in prognosis and progression of Wilms' tumor (WT). METHODS: Four pairs of WT and adjacent tissues were collected for high-throughput circRNA sequencing to identify the differentially expressed circular RNAs. RT-qPCR was used to verify the expression levels of the top 6 candidate circRNAs in the clinical samples. hsa_circ_0001900 was selected for analysis of its correlation with clinicopathological features and prognosis in 34 patients with WT. Sanger sequencing and RNase R digestion experiments were used to verify the cycling site and structural stability of hsa_circ_0001900 molecule. RESULTS: A total of 23 978 circular RNA molecules were identified in WT tissues by high-throughput circular RNA sequencing, and among them 614 were differentially expressed in WT. hsa_circ_0001900 showed the highest expression level among the differentially expressed circRNAs, which was consistent with the findings in clinical tumor samples and the sequencing results. Correlation analysis showed that hsa_circ_0001900 expression level was positively correlated with WT volume, and the children with high hsa_circ_0001900 expression had a lowered recurrence-free survival rate. The results of Sanger sequencing verified the circular splice site sequence of the molecule, and Rnase R digestion assay confirmed its stable covalent structure. CONCLUSIONS This study presents a comprehensive expression profile of circular RNAs in WT, and the expression level of hsa_circ_0001900 is related to the size of WT and the patients' prognosis, suggesting its possible role as a key driving gene in WT progression.

Gap junction proteins have a significant impact on the propagation of neuroinflammation after cerebral ischemia.Connexin 43(Cx43),the principal connexin in the central nervous system,typically assembles hexameric hemichannels in an oligomeric state that dock with hemichannels on adjacent cells to form gap junction channels.Ordinarily,the likelihood of cell surface hemichannels opening is minimal.However,during cerebral ischemia,the excessive activation of Cx43 hemichannels leads to the liberation of a substantial quantity of ions(Na+,Cl-,Ca2+,and K+),glutamate,aspartate,and adenosine triphosphate(ATP),thereby resulting in impairment of adjacent cells and aggravation of neuronal injury.Furthermore,the activation of Cx43 hemichannels triggers the release of inflammatory factors,which exhibits a strong association with the activation of NLRP3 inflammasome after cerebral ischemia.Hence,the modulation of Cx43 hemichannels presents a potential avenue for mitigating neuroinflammation and subsequently diminishing cerebral ischemic injury.This article focuses on the relationship between Cx43 hemichannels and NLRP3 inflammasome activation,as well as its role in cerebral ischemia,all of which provide novel insights and therapeutic approaches for managing cerebral ischemia.

Objective:To investigate the influencing factors of secondary osteoporosis in stroke patients with hemiplegia, and to construct a nomogram prediction model and evaluate it.Methods:The study subjects were 110 patients with hemiplegia after stroke who were treated in our hospital from Jun. 2019 to Jun. 2023, and were divided into osteoporosis group and non-osteoporosis group by bone mineral density detection. Clinical data and laboratory indicators were collected. Single factor analysis and binary Logistic multiple factor regression analysis were used to screen the influencing factors. R software (R3.3.2) and software package rms were used to construct the nomogram prediction model.Results:There were 52 patients with osteoporosis and 58 patients without osteoporosis. In the osteoporosis group, the proportion of female, unilateral anterior circulation multiple infarction and less sunlight was significantly higher than that in the non-osteoporosis group, with statistical significance ( χ2=8.27, 14.77 and 6.96, respectively, P<0.05). Systolic blood pressure (159.32±21.72 vs. 151.67±19.52), total cholesterol (4.29±0.50 vs. 3.57±0.42), LDL-C (2.87±0.33 vs. 2.04±0.31), Hcy (3.81±2.51 vs. The level of 112.33±2.47 was significantly higher than that of the non-osteoporosis group, and the difference was statistically significant ( t was 5.23, 8.38, 7.98 and 5.63, respectively, P<0.001). The level of albumin (38.15±5.21 vs. 33.26±5.73) was significantly lower than that of the non-osteoporosis group. The difference was statistically significant ( t=4.90, P<0.05). Binary Logistic regression analysis showed that female, higher total cholesterol, LDL-C, Hcy levels and less sun exposure were independent risk factors for secondary osteoporosis in stroke patients with hemiplegia ( P<0.05). ROC curve analysis results showed that the area under the curve of the established model to predict secondary osteoporosis in stroke hemiplegia patients was 0.891 (0.833-0.949), and the sensitivity and specificity were 80.8% and 79.3%, respectively. Conclusion:The categorization and consistency of the nomogram model based on the influencing factors of secondary osteoporosis in patients with stroke hemiplegia are good, which can provide a certain reference for the identification and early intervention of high-risk groups with stroke hemiplegia.

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 identify the key genes differentially expressed in Wilms tumor and analyze their potential impacts on prognosis and immune responses of the patients. Methods High-throughput RNA sequencing was used to identify the differentially expressed mRNAs in clinical samples of Wilms tumor and paired normal tissues, and their biological functions were analyzed using GO, KEGG and GSEA enrichment analyses. The hub genes were identified using STRING database, based on which a prognostic model was constructed using LASSO regression. The mutations of the key hub genes were analyzed and their impacts on immunotherapy efficacy was predicted using the cBioPortal platform. RT-qPCR was used to verify the differential expressions of the key hub genes in Wilms tumor. Results Of the 1612 differentially expressed genes identified in Wilms tumor, 1030 were up-regulated and 582 were down-regulated, involving mainly cell cycle processes and immune responses. Ten hub genes were identified, among which 4 genes (TP53, MED1, CCNB1 and EGF) were closely related to the survival of children with Wilms tumor. A 3-gene prognostic signature was constructed through LASSO regression analysis, and the patients stratified into with high- and low-risk groups based on this signature had significantly different survival outcomes (HR=1.814, log-rank P=0.002). The AUCs of the 3-, 5-and 7-year survival ROC curves of this model were all greater than 0.7. The overall mutations in the key hub genes or the individual mutations in TP53/CCNB1 were strongly correlated with a lower survival rates, and a high TP53 expression was correlated with a poor immunotherapy efficacy. RT-qPCR confirmed that the key hub genes had significant differential expressions in Wilms tumor tissues and cells. Conclusion TP53 gene plays an important role in the Wilms tumor and may potentially serve as a new immunotherapeutic biomarker as well as a therapeutic target.

Objective:To explore and analyze the predictive value of EuroSCORE Ⅱ and SYNTAX Ⅱ scores for clinical outcomes in patients undergoing coronary artery bypass grafting (CABG) surgery.Methods:A total of 500 coronary artery disease (CAD) patients who underwent CABG in Shanxi Cardiovascular Hospital from April 2014 to July 2023 were selected as the study subjects, all patients were given EuroSCORE Ⅱand SYNTAX Ⅱ scores to evaluate the predictive value of EuroSCOREⅡfor perioperative mortality and SYNTAX Ⅱ for 4-year mortality. Univariate and multivariate Logistic analysis were employed to analyze the independent risk factors for perioperative and 4-year mortality.Results:There were 3 deaths during the perioperative period, with a mortality rate of 0.60%, the predicted mortality rate of EuroSCOREⅡwas 1.71%; there were 21 deaths at 4 years after surgery, with a mortality rate of 4.23% and the predicted mortality rate of SYNTAX Ⅱwas 9.02%. Logistic regression analysis showed that left ventricular ejection fraction (LVEF) was the only independent protective factor for perioperative mortality, and advanced age was the only independent risk factor for 4-year postoperative mortality in patients ( P<0.05). The analysis of the working characteristic curve of the subjects found that the area under the receiver operating characteristic curve ( ROC) of EuroSCORE Ⅱ for perioperative mortality was 0.782, and the area under ROC curve of SYNTAX Ⅱfor postoperative 4-year mortality was 0.743. Conclusion:Both EuroSCORE Ⅱand SYNTAX Ⅱhave certain predictive value for perioperative mortality and postoperative 4-year mortality in patients undergoing CABG, respectively, but the predicted mortality rate is relatively higher.
