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 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 discuss the association between occupational acid fog exposure and accelerated biological aging of the workers,and to clarify its related risk factors.Methods:A total of 341 male workers exposed to occupational acid fog and 201 male workers without occupational exposure were selected as the study subjects,and they were divided into exposure group and control group,respectively.The general informations of the subjects in two groups were collected through questionnaires and physical examinations.The levels of red blood cell count(RBC),platelet count(PLT),albumin(ALB),urea(Urea),creatinine(CR),triglycerides(TG),total cholesterol(TC),glycated hemoglobin(HBA1c),and high-sensitivity C-reactive protein(Hs-CRP)in serum of the subjects in two groups were detected.The Klemera-Doubal method(KDM)was used to construct the composite aging measure,KDM-biological age(BA)(KDM-BA).The model parameters were trained using samples from the 2009 China Health and Nutrition Survey(CHNS)Database to calculate the BA acceleration of the subjects in two groups;stratified analysis based on the population characteristics was conducted to analyze the BA of the subjects in two groups with different population characteristics;generalized linear model was used to analyze the factors influencing BA acceleration due to acid fog exposure.Results:The model parameters were trained using samples from the 2009 CHNS Database,including 8 133 cases aged 20-79 years,of which 3 788 were male.The levels of Urea,CR,HBA1c,ALB,and TC,as well as systolic blood pressure(SBP),total working years,sleep duration,and body mass index(BMI)of the subjects between two groups had significant differences(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05).In entire population and exposure group,the BA acceleration in the smokers was significantly higher than that in the non-smokers(P<0.05).In entire population,control group,and exposure group,the BA accelerations of the subjects in different BMI groups were significantly decreased with the increase of BMI(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05),including those under 40 years old,with total working years of 4-7 years,Han nationality,unmarried,smokers,and sleep duration 6-7 h,and with overweight.Acid fog exposure,smoking,and BMI were associated with the BA acceleration(β=0.72,95%CI:0.24-1.21;β=0.59,95%CI:0.11-1.06;β=-0.29,95%CI:-0.35—-0.22).Conclusion:Occupational acid fog exposure may accelerate the biological aging in the workers,and acid fog is a risk factor to accelerate the biological aging of the body.

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.

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.
