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 explore potential association between sedentary time and the risk of all-cause mortality and cardiovascular disease(CVD)in Chinese population using data from the Prospective Urban Rural Epidemiology(PURE-China)cohort study.Methods Baseline data were collected,from 2022 standardized questionnaires and physical examinations,with follow-up until August 31,2022.The primary endpoints were all-cause mortality and cardiovascular events(non-fatal myocardial infarction,stroke or heart failure).Multivariable Cox shared frailty model was used to analyze the association between sedentary time and the risks of all-cause mortality and CVD in the target population,and to compare differences across subgroups based on gender,age and geographic location.Results A total of 47 931 participants were recruited,and 43 367 were included in the final analysis.Over a me-dian follow-up of 11.9±3.0 years,2 277 participants experienced all-cause mortality,3 551 experienced cardiovas-cular events.The Cox model indicated that,compared to individuals with less than 4 h of sedentary time per day,those with 6-8 h had a 23％increased in risk of all-cause mortality(HR=1.23,95％CI:1.06-1.44)and an 18％increased risk of CVD(HR=1.18,95％CI:1.04-1.33).For individuals with more than 8 h of sedentary time,the risk increased by 50％for all-cause mortality(HR=1.50,95％CI:1.16-1.94)and 44％for CVD(HR=1.44,95％CI:1.16-1.79).These associations were more pronounced in men and individuals aged 50 years and older.Conclusions Sedentary behavior is associated with an increased risk of all-cause mortality and cardiovascular disease in Chinese population,especially in the population with sedentary time of 6 hrs or more per day.Reducing sedentary time and increasing physical activity is an important strategy to mitigate the disease burden of cardiovascular disease and premature death.

Objective:To investigate the current application of blood purification in the treatment of acute poisoning within Jiangsu Province and to evaluate the impact of extracorporeal blood purification on the clinical outcomes of critically poisoned patients.Methods:This multicenter, cross-sectional real-world observational study followed patients presenting with poisoning to the emergency departments of nine hospitals in Jiangsu Province between June 2015 and May 2019. Data were collected on demographic characteristics, vital signs within the first hour of emergency presentation, treatment modalities, length of hospital stay, and survival outcomes. Clinical data from patients who underwent extracorporeal blood purification were compared with those who did not, using the Wilcoxon rank-sum test and Chi-square test.Results:A total of 4 178 poisoning cases were included between June 2015 and May 2019. Among them, 21.7% (908/4 178) received blood purification therapy, while 78.3% (3 270/4 178) did not. Hemoperfusion (90.4%) was the most frequently employed method, followed by continuous renal replacement therapy (CRRT) (4.4%). In combined blood purification modalities, 4.8% underwent hemoperfusion combined with CRRT, 0.1% received hemoperfusion with plasma exchange, and another 0.1% underwent hemoperfusion combined with both CRRT and plasma exchange. Among patients who underwent blood purification, pesticide poisoning was the most prevalent (76.3%), with the most common toxic agents being paraquat (23.7%), dichlorvos (8.7%), methamidophos (5.2%), omethoate (4.0%), and glyphosate (3.7%). Compared to the non-blood purification group, patients in the blood purification group were more likely to present within the first hour with a low Glasgow Coma Scale (GCS) score (3-8) (22.6% vs. 9.7%, P <0.05), low mean arterial pressure (8.0% vs. 3.2%, P <0.05), longer hospital stays [5(3,9) days vs. 2(1,4) days, P <0.05] and a higher in-hospital mortality rate (21.1% vs. 5.3%, P <0.05). Follow-up via telephone 28 days after discharge revealed a survival rate of 78.9%, with a mortality rate of 21.1% in the blood purification group. Conclusions:Hemoperfusion is the most commonly utilized blood purification technique for treating poisoning in Jiangsu Province, with pesticides being the primary toxic agents treated. Although the mortality rate is higher in the blood purification group, the intervention may still contribute to improved patient outcomes.

Objective To compare the therapeutic impact of acute anterior wall ST-segment elevation myocardial infarc-tion(STEMI)and primary percutaneous coronary intervention(PCI)in patients with heart failure.Methods 90 patients with anterior wall STEMI with heart failure after primary PCI were selected from the cardiovascular Department of Yunfu People's Hos-pital from July 2021 to June 2023,and they were split into three groups using the random number expression approach,each group containing 30 examples.Group A was treated with furosemide+nitroglycerin,group B was treated with furosemide+nitro-glycerin+neoactin,and group C was treated with furosemide+nitroglycerin+dopamine.The clinical efficacy,cardiac function[left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),left ventricular ejection frac-tion(LVEF),amino terminal B-type natriuretic peptide precursor(NT-ProBNP)]and clinical indexes of the three groups after treatment were compared.Results ①There was significant difference in total treatment rate among the three groups(P＜0.05).Group B and C had significantly greater total effective rates than group A.(P＜0.05).②After 3 days of treatment,the levels of LVEF in the three groups were increased(P＞0.05),while the levels of NT-ProBNP,LVESD and LVEDD were decreased,and the levels of NT-ProBNP,LVESD and LVEDD in group B and C were lower than those in group A(all P＜0.05).③The length of hospital stay and readmission rate of the three groups were significantly different(P＜0.05).The length of hospital staying and readmission rate of group B and C were lower than those of group A(P＜0.05).Conclusion Furosemide+nitroglycerin combined with neoactin or dopamine in the treatment of anterior wall STEMI patients with heart failure after primary PCI is more effective,can enhance patients'heart health,shorten the length of hospital stay,reduce the readmission rate,worthy of clinical promotion.

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.

Objective To investigate the expression of tissue signal transducer and activator of transcription 3(STAT3)and serum STAT3 mRNA,IL-12p40 and IL-13R α 2 levels in children with congenital intestinal atresia and their correlation with prognosis.Methods From January 2020 to January 2023,100 cases of intestinal atresia lesion tissues,normal intestinal tissues and preoperative serum samples were collected from children with congenital intestinal atresia who underwent treatment in Hebei Children's Hospital.According to the Grosfeld typing criteria,these children were categorized into 39 cases of type Ⅰ,22 cases of type Ⅱ,30 cases of type Ⅲ and 9 cases of type Ⅳ.Based on the recovery situation at 6 months after surgery,these children were separated into a good prognosis group(n=78)and a poor prognosis group(n=22).Serum samples from 93 cases of healthy children undergoing medical examinations during the same period were regarded as control samples.Immunohistochemistry was applied to detect the positive expression and localization of STAT3 in tissues.Western blot was applied to detect the expression of STAT3 protein in tissues,and quantitative polymerase chain reaction(qPCR)was applied to detect the expression level of STAT3 mRNA in serum.Pearson correlation was applied to analyze the correlation between serum STAT3 and inflammatory factor levels in children with congenital intestinal atresia.Logistic regression was used to analyze the factors affecting the prognosis of children with congenital intestinal atresia.Receiver operating characteristic(ROC)curve was applied to analyze the predictive efficacy of serum STAT3 level on the prognosis of children with congenital intestinal atresia.Results Immunohistochemical results showed that STAT3 positive expression was mainly localized in the cytoplasm and nucleus.The positive expression rate in congenital intestinal atresia tissue(86％)was higher than that in normal intestinal tissue(18％),and the difference was significant(x2=92.628,P＜0.05).Western blot results showed that the relative expression level of STAT3 in congenital intestinal atresia tissue(1.59±0.21)was higher than that in normal intestinal tissue(0.81±0.12),and the difference was significant(t=30.567,P＜0.05).The results of qPCR showed that serum STAT3(2.13±0.56),IL-12p40(0.89±0.13 ng/ml),and IL-13R α 2 levels(6.42±1.86ng/ml)in the congenital intestinal atresia group were higher than those in the control groups(1.06±0.11,0.37±0.08ng/ml,1.35±0.41ng/ml),and the differences were significant(t=18.101,33.170,25.708,all P＜0.05).The levels of STAT3 and IL-12p40,IL-13R α 2 were gradually increased with the increase of the children's subtypes,and the differences were significant(F=52.666,160.300,25.82,all P＜0.05).Pearson correlation analysis showed a positive correlation between serum STAT3,IL-12p40,and IL-13R α 2 levels in children with congenital intestinal atresia(r=0.496,0.564,all P＜0.001).The expression level of serum STAT3 in poor prognosis group(3.01±0.75)was higher than that in good prognosis group(1.88±0.51),and the differences was statistically significant(t=8.212,P＜0.05).Logistic regression showed that STAT3,IL-12p40,IL-13R α 2,and low birth quality were all independent risk factors for poor prognosis in children with congenital intestinal atresia(all P＜0.05).The ROC curve showed that the area under the curve(AUC)for evaluating the prognosis of children with congenital intestinal atresia by serum STAT3 expression was 0.916,with a sensitivity of 81.82％and a specificity of 88.46％,respectively.When the serum STAT3 mRNA level was higher than 2.47,children with congenital intestinal atresia had a higher probability of poor prognosis.Conclusion The expression of STAT3 is increased in the tissues and serum of children with congenital intestinal atresia.Serum STAT3 may have a predictive value for the prognosis of affected children.

The pursuit of cosmetic effects in post-surgical wounds has led to the development of ultra-minimally invasive techniques in surgery. Minimal invasive surgery has replaced open surgery and has become the new gold-standard for treating diseases. One such technique is the single incision triangulated umbilicus surgery (SITUS), which offers several advantages over traditional laparoscopic and other scarless surgeries, including reduced trauma, faster recovery, and better cosmetic outcomes. SITUS also has a short learning curve, aligns with conventional instrumentation operating habits, and can be used for whole abdominal surgeries. Chinese scholars have made further improvements to the SITUS technology, including expanding its applicability in intra-abdominal surgery and refining its incision closure methods to achieve superior cosmetic results. Currently, SITUS technology is experiencing rapid development in urology applications and has demonstrated satisfactory results in both domestic and international reports. This review aims to discuss the effectiveness and development of the SITUS technique in urology.
