Objective: : The objective of this study was to assess the relationship between spermine synthase (SMS) expression, tumor occurrence, and prognosis in lower-grade gliomas (LGGs). Methods: : A total of 523 LGG patients and 1152 normal brain tissues were included as controls. Mann-Whitney U test was performed to evaluate SMS expression in the LGG group. Functional annotation analysis was conducted to explore the biological processes associated with high SMS expression. Immune cell infiltration analysis was performed to examine the correlation between SMS expression and immune cell types. The association between SMS expression and clinical and pathological features was assessed using Spearman correlation analysis. In vitro experiments were conducted to investigate the effects of overexpressing or downregulating SMS on cell proliferation, apoptosis, migration, invasion, and key proteins in the protein kinase B (AKT)/epithelialmesenchymal transition signaling pathway. Results: : The study revealed a significant upregulation of SMS expression in LGGs compared to normal brain tissues. High SMS expression was associated with certain clinical and pathological features, including older age, astrocytoma, higher World Health Organization grade, poor disease-specific survival, disease progression, non-1p/19q codeletion, and wild-type isocitrate dehydrogenase. Cox regression analysis identified SMS as a risk factor for overall survival. Bioinformatics analysis showed enrichment of eosinophils, T cells, and macrophages in LGG samples, while proportions of dendritic (DC) cells, plasmacytoid DC (pDC) cells, and CD8+ T cells were decreased. Conclusion : High SMS expression in LGGs may promote tumor occurrence through cellular proliferation and modulation of immune cell infiltration. These findings suggest the prognostic value of SMS in predicting clinical outcomes for LGG patients.

Objective:To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application.Methods:A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1∶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively.Results:A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] ( Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=-2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ 2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference ( Z=-0.78, P=0.439). Conclusions:Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

CircRNA is a new endogenous non-coding RNA(ncRNA ) and a member of the competitive endogenous RNA(ceRNA) family. Some researches have found that circRNA exists widely in organisms and interacts with miRNA, which has certain influence on the occurrence and development of liver diseases. This article reviews the research progress of circRNA and its biological functions, as well as the relationship between circRNA and liver disease, in order to expound the role of circRNA in liver diseases and guide clinical practice better.

Objective: To analyze the relationship between clinical characteristics and prognosis of patients with acute herbicide poisoning marked diquat. Methods: A multi-center, retrospective clinical study of patients with acute diquat poisoning admitted into Emergency Department was conducted from June 2015 to August 2018 in 8 hospitals in Jiangsu Province. Results: A total of 43 patients (22 males and 21 females) were collected and the peak age of poisoning ranged 20-39 years old. The only route of poisoning was ingestion. Among these cases, suicide was the most common cause of poisoningaccounting for 90.70%. In emergency treatment, the constituent ratios of gastric lavage, hemoperfusion and glucocorticoid were 87.50%, 72.50% and 42.50%, respectively. The total mortality increased to 60.00% after follow-up, while the in-hospital mortality was 18.60%. The mortality of patients with toxic dose < 50 mL was 11.11%. Conclusions The incidence of acute herbicide poisoning with "diquat" as commercial component is gradually increasing. At present, the mortality is very high. Ingestion poisoning dose is the key factor affecting prognosis, and the prognosis of patients with oral dose > 50 mL is poor.

Objective To explore the relations between pulse pressure and LDL-C for elderly patients with hyperten-sion. Methods A total of 451 elderly patients with hypertension were selected and divided into four groups. Group A was 65 to 69 years of age, group B was 70 to74 years of age, group C was 75 to 79 years of age, and group D was ≥80 years of age. They were also divided into four groups according to PP levels: PP1 group ≤40 mm Hg, PP2 group 41 to 60 mm Hg, PP3 group 61 to 80 mm Hg, and PP4 group>80 mm Hg. They were divided into LDL-C group 1 (≥2.6 mmol/L) and LDL-C group 2 (<2.6 mmol/L) according to their LDL-C levels. Distribution of different age groups in four PP groups and the effects of different levels of LDL-C on pulse pressure were analyzed. Results (1) The propor-tions of PP2 group among the four age groups were 59.41%, 48.84%, 55.45% and 51.67%. The proportions of PP4 a-mong the four age groups were 4.95%, 3.88%, 3.96% and 7.50%. (2) Compared with PP1 group, the proportion of LDL-C ≥2.6 mmol/L in PP2 group, PP3 group and PP4 group was significantly increased. Conclusion (1) PP levels in different ages groups are concentrated on 41-60 mmHg. Among elderly patients with hypertension>80 mmHg, the pro-portion of patients with advanced age (≥years of age) is relatively higher. (2) LDL-C is the risk factor of increased pulse pressure for elderly patients with hypertension.
