Objective: To systematically evaluate the association between random urinary electrolyte levels and hypertension among children and adolescents in Guizhou Province, so as to provide evidence for region specific dietary guidance and interventions. Methods: In 2023, a total of 2 480 children and adolescents aged 6 to 17 years were recruited from a nine-year coherent style school in Guizhou Province in a children health cohort, with follow ups conducted in 2024 and 2025. Random urine samples were collected to measure urinary sodium, potassium, calcium, and chloride, and the urinary sodium to potassium ratio (Na/K) was calculated. The diagnosis of hypertension was based on the criteria established by the Chinese Guidelines for Hypertension Prevention and Treatment (2024 revised edition) and relevant research. Linear mixed models and multinomial Logistic regression were used to assess the associations of urinary electrolytes with systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and the risk of hypertension. Results: At baseline, SBP, DBP, and MAP were 102.33 (94.33, 110.33), 61.33 (56.33, 67.00) and 75.22 (69.67, 81.33)mmHg among children and adolescents, respectively. After adjusting for potential confounders and two follow-ups, higher urinary Na/K ratio was positively associated with higher of SBP ( β=0.054, 95%CI =0.028- 0.081 ) and MAP ( β=0.038, 95%CI =0.010-0.066), as well as higher risks of hypertension ( OR=1.248, 95%CI =1.006-1.548) (all P <0.05). Higher of urinary chloride levels were positively associated with higher of SBP ( β=0.088, 95%CI = 0.009- 0.167), whereas higher of urinary potassium (SBP: β=-0.062, 95%CI =-0.096 to -0.028; MAP: β=-0.041, 95%CI = -0.078 to -0.005) and calcium levels (SBP: β=-0.036, 95%CI =-0.065 to -0.007) were negatively associated with blood pressure (all P < 0.05 ). Conclusion The urinary Na/K, as a comprehensive electrolyte marker, more stably reflects sodium load and excretory pressure in children and adolescents, and may serve as an early predictor of hypertension risk.

OBJECTIVE To investigate the protective effects and potential mechanism of alisol B 23-acetate on acute alcoholic liver injury in mice. METHODS Fifty male Kunming mice were divided into the blank group， model group， and alisol B 23-acetate low-， medium- and high-dose groups （10， 20， 40 mg/kg）， with 10 mice in each group. Each group was given relevant drug solution or normal saline intragastrically， once a day， for 2 consecutive weeks. On the 15th day， mice in the blank group were given normal saline intragastrically， while the other four groups were given 12 mL/kg white wine intragastrically， twice at six-hour intervals， to establish an acute alcoholic liver injury model. On the 16th day of the experiment， the liver indexes of mice in each group were calculated； the serum levels of alanine transaminase （ALT）， aspartate transaminase （AST）， total cholesterol （TC）， triglycerides （TG）， malondialdehyde （MDA） and glutathione （GSH） were also determined. The histopathological morphology of their liver tissues was observed and scored. The protein expressions of cytochrome P450 2E1 （CYP2E1）， Kelch-like ECH-associated protein 1 （Keap1）， nuclear factor erythroid 2-related factor 2 （Nrf2） and NAD（P）H： quinone oxidoreductase 1 （NQO1） were measured in liver tissue. RESULTS Compared with model group， mice in each dosage group of alisol B 23-acetate showed varying degrees of recovery in body weight， along with improvements in pathological changes in liver tissues such as inflammatory cell infiltration and fatty vacu oles. Their liver indexes， histopathological scores of liver tissue， serum levels of ALT， AST， TC， TG and MDA， as well as the protein expressions of CYP2E1 and Keap1 in liver tissue， were all significantly decreased （ P ＜0.05 or P ＜0.01）. The serum GSH levels and the protein expressions of Nrf2 （except for the alisol B 23-acetate low-dose group） and NQO1 in liver tissue were significantly increased （ P ＜0.05 or P ＜0.01）， and the changes in the above quantitative indicators showed a dose-dependent pattern. CONCLUSIONS Alisol B 23-acetate can ameliorate acute alcoholic liver injury in mice， and its mechanism may be related to improving antioxidant capacity by regulating the Keap1/Nrf2/NQO1 signaling pathway while simultaneously improving liver lipid metabolism-related indexes.

Objective To understand the current status of blood pressure variability and dyslipidemia in young and middle-aged patients with ischemic stroke, and to explore their relationship with prognosis. Methods A total of 312 young and middle-aged patients with ischemic stroke who met the inclusion criteria in Beijing Pinggu District Hospital from January 2022 to January 2025 were selected. The prognosis status [modified Rankin scale (mRS)], blood pressure variability, and blood lipids [total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] were analyzed. The correlation of blood pressure variability and blood lipids levels with prognosis was explored by logistic regression analysis. Results There were 206 patients with good prognosis and 106 patients with poor prognosis. The number of patients who received diversified health education in the good prognosis group was more than that in the poor prognosis group (P<0.05). The systolic blood pressure successive variation (SV) and average real variability (ARV), and diastolic blood pressure SV and ARV were lower in the good prognosis group than those in the poor prognosis group (P<0.05). Furthermore, compared with the poor prognosis group, the good prognosis group had lower levels of TC, TG and LDL-C, while the number of patients receiving diversified health education and the level of HDL-C were higher (P<0.05). After logistic regression analysis, it was found that the levels of TC, TG, LDL-C, systolic blood pressure SV and ARV, and diastolic blood pressure SV and ARV were risk factors for poor prognosis. Conversely, receiving diversified health education and HDL-C level were protective factors for poor prognosis (P<0.05). Conclusion High blood pressure fluctuation, dyslipidemia, and lack of health education will increase the risk of poor prognosis in young and middle-aged stroke patients.

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.

Riboflavin-ultraviolet A (UVA) collagen cross-linking has not only achieved good clinical efficacy in the treatment of corneal diseases such as dilatation keratopathy, bullae keratopathy, infectious keratopathy, and in the combined treatment of corneal refractive surgeries, but also its efficacy and safety in scleral collagen cross-linking have been initially confirmed. To better promote the application of cross-linking in the clinical treatment of corneal and scleral diseases, exploring controllability and predictability of the surgical efficacy are both important for evaluating the surgical efficacy and personalized precision treatment. In this paper, the progress on the cross-linking depth of riboflavin-UVA collagen cross-linking, and its relationship with the cross-linking effect will be reviewed. It will provide the reference for further application of this procedure in ophthalmology clinics.

OBJECTIVES: To explore the molecular mechanism by which lncRNA SNHG15 regulates proliferation, invasion and migration of lung adenocarcinoma cells. METHODS: The lncRNA microarray chip dataset GSE196584 and LncBase were used to predict the lncRNAs that interact with miR-30b-3p, and their association with patient prognosis were investigated using online databases, after which lncRNA nucleolar RNA host gene 15 (SNHG15) was selected for further analysis. The subcellular localization of lncRNA SNHG15 and its expression levels in normal human lung epithelial cells and lung adenocarcinoma cell lines were detected using fluorescence in situ hybridization and qRT-PCR. In cultured A549 cells, the changes in cell proliferation, migration, and invasion following transfection with a SNHG15 knockdown plasmid (sh-SNHG15), a miR-30b-3p inhibitor, or their co-transfection were assessed with EdU, wound healing, and Transwell assays. Bioinformatics analyses were used to predict the regulatory relationship between lncRNA SNHG15 and COX6B1, and the results were verified using Western blotting and rescue experiments in A549 cells transfected with sh-SNHG15, a COX6B1-overexpressing plasmid, or both. RESULTS: LncRNA SNHG15 was shown to target miR-30b-3p, and the former was highly expressed in lung adenocarcinoma, and associated with a poor patient prognosis. LncRNA SNHG15 was localized in the cytoplasm and expressed at higher levels in A549 and NCI-H1299 cells than in BEAS-2B cells. In A549 cells, lncRNA SNHG15 knockdown significantly inhibited cell migration, invasion and proliferation, and these changes were reversed by miR-30b-3p inhibitor. A regulatory relationship was found between lncRNA SNHG15 and COX6B1, and their expression levels were positively correlated (r=0.128, P=0.003). MiR-30b-3p knockdown obviously decreased COX6B1 expression in A549 cells, and COX6B1 overexpression rescued the cells from the inhibitory effects of lncRNA-SNHG15 knockdown. CONCLUSIONS LncRNA SNHG15 may compete with COX6B1 to bind miR-30b-3p through a ceRNA mechanism to affect proliferation, migration, and invasion of lung adenocarcinoma cells.

Objective To investigate the relationships of computed tomography (CT) angiography (CTA)-derived coronary plaque properties with platelet function and whole blood cell-derived inflammatory markers in elderly patients with coronary heart disease. Methods The clinical data of 142 elderly patients with coronary heart disease who underwent coronary CTA examination in the hospital between April 2022 and April 2025 were retrospectively analyzed. The CT value of CTA, platelet function parameters (mean platelet volume, platelet-derived growth factor BB, von Willebrand factor), and whole blood cell-derived inflammatory markers were recorded at admission. The correlations of the CT value of CTA-derived coronary plaque properties with platelet function parameters and whole blood cell-derived inflammatory markers in elderly patients with coronary heart disease were analyzed using Pearson correlation coefficients. Based on the evaluation of CTA-derived coronary plaque properties, the patients were divided into a soft plaque group (CT value ≤ 60 HU), a calcified plaque group (CT value ≥ 130 HU), and a mixed plaque group (60 HU < CT value < 130 HU). The platelet function parameters (mean platelet volume, platelet-derived growth factor BB, von Willebrand factor) and whole blood cell-derived inflammatory markers (systemic immune-inflammation index, systemic inflammation response index, neutrophil-to-lymphocyte ratio, and monocyte-to-lymphocyte ratio) on admission were compared among the three groups. Results The coronary CTA examination showed 37 (26.06%) cases in the calcified plaque group, 47 (33.10%) cases in the soft plaque group, and 58 (40.84%) cases in the mixed plaque group. The CT values were (189.57 ± 22.14) HU for the calcified plaque group, (31.74 ± 4.12) HU for the soft plaque group, and (94.52 ± 8.29) HU for the mixed plaque group. The levels of platelet function parameters and whole blood cell-derived inflammatory markers at admission were in the following order: soft plaque group > mixed plaque group > calcified plaque group, and the differences were statistically significant (P < 0.05). After adjustment for sex, age, cardiac function grading, hypertension, diabetes, and blood lipids as covariates, partial correlation analysis revealed that the CT value of CTA-derived coronary plaque properties in elderly patients with coronary heart disease was negatively correlated with the levels of platelet function parameters and whole blood cell-derived inflammatory markers (P < 0.05). Conclusion In this study, the coronary plaque CT value in elderly patients with coronary heart disease was negatively correlated with the levels of platelet function parameters and whole blood cell-derived inflammatory markers. Furthermore, increasing plaque instability may be associated with more pronounced platelet activation and a heightened systemic inflammatory state.

OBJECTIVE: To explore the clinical phenotypes and genetic characteristics of a pedigree with Distal arthrogryposis type 5D (DA5D) caused by compound heterozygous variants in the ECEL1 gene. METHODS: A child (proband) diagnosed with DA5D and his family members (proband's parents and sister) who was admitted to the Department of Rehabilitation Medicine of Henan Children's Hospital in July 2022 due to "multiplex distal arthrogryposis" were enrolled into this study. Clinical data of the proband were collected and peripheral blood samples were obtained from the proband and members of his family about 3 mL. Trio-whole genome sequencing (trio-WGS) was carried out to detected the genetic variations of the proband and his family members. The candidate's pathogenic gene variants were screened and analyzed by Genome Aggregation Database (gnomAD) and other databases. The screened variants were annotated for clinical phenotypes using databases like the Online Mendelian Inheritance in Man (OMIM). The pathogenicity of the candidate variants was predicted by bioinformatics tools such as Provean. Based on the guidelines of the American College of Medical Genetics and Genomics (ACMG), pathogenicity ratings were conducted for variant sites. The protein conservation and mutation structure prediction of ECEL1 protein among species were carried out though MEGA-X and PyMOL. The research protocol of this study was reviewed by the Ethics Committee of Henan Provincial Children's Hospital (Approval No. 2023-H-H01), and informed consent for clinical research was obtained from the guardians of the probands. RESULTS: The proband had multiplex distal arthrogryposis involving hands, feet, knees, and ankles, and had right ptosis, micrognathia, low auricular position, and upturned nose. The parents and sister both had normal phenotypes. Trio-WGS and Sanger sequencing revealed that the child had compound heterozygous variants of paternal c.1742_c.1743insT and maternal c.2314T>G, for which the father and sister were carriers of the c.1742_c.1743insT heterozygous variant and the mother was carrier of c.2314T>A. Neither mutation site has been reported. According to guidelines of ACMG, the c.1742_c.1743insT variant was classified as likely pathogenic (PSV1+PM2_Supporting), and c.2314T>G was classified as uncertain (PM2_Supporting+PM3+PP3). The results of conserved analysis of amino acid residue sequences of ECEL1 protein showed that the missense mutation of the maternal c.2314T>G (p.Cys772Gly) was highly conserved among humans and other seven species. The protein structure prediction revealed that the c.1742_c.1743insT frameshift mutation led to the protein truncation, and the c.2314T>G missense mutation resulted in the failure of forming 1 disulfide bond. CONCLUSION The compound heterozygous variants of ECEL1 gene were considered to be pathogenic for this DA5D patient, which have expanded the mutational spectrum of the ECEL1 gene and provided a reference for clinical diagnosis as well as genetic counseling for this family.

Objective:To compare the training effect between the laparoscopic simulated uterine model (LSUM) with multi-angle suture and the traditional surgical model and to identify a laparoscopic model more suitable for gynecological resident training.Methods:Forty-eight residents who were trained in Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine from February 2021 to February 2023 were selected. They were trained in batches, with each batch randomly divided into two groups of the same size. The observation group was trained with the traditional surgical model and general surgical videos, while the experimental group was trained with a self-developed LSUM with multi-angle suture and corresponding surgical videos. Finally, the two groups were compared for the assessment results, and a questionnaire survey was conducted in the experimental group. The statistical software SPSS 20.0 was used for t-test or chi-square test of the results. Results:There were no significant differences between the two groups in age, gender distribution, education level, and clinical experience. In theoretical assessment results, no significant difference was shown between the experimental group and the observation group [(82.63±3.93) vs. (85.00±6.15), P>0.05]. In skill assessment results, there was no significant difference between the two groups in the anterior wall assessment [(83.08±4.47) vs. (82.79±3.58), P=0.804]. However, in the assessment of the lateral and posterior walls, the proficiency, accuracy, and degree of coordination between two hands of the experimental group were better than those of the observation group, with the total score being significantly different [(64.13±3.34) vs. (46.75±3.50), (62.25±4.41) vs. (45.00±2.89), P<0.001]. In the questionnaire survey, the experimental group had a high degree of satisfaction with the LSUM and thought that the highly simulated model was beneficial to their training. Conclusions:Compared with the traditional surgical model, the LSUM with multi-angle suture can effectively improve the operation level of residents, which provides a new idea for the laparoscopic simulation training of gynecological residents in the future.
