OBJECTIVE To assess the correlation between the steady-state minimal concentration (cmin) and 24 h area under the drug concentration-time curve (AUC24)/minimal inhibitory concentration (MIC) ratio (AUC24/MIC) of vancomycin in pediatric patients, and analyze independent risk factors for treatment failure. METHODS Data of hospitalized children treated with vancomycin and receiving therapeutic drug monitoring in our hospital from January 2021 to July 2024 were retrospectively collected and divided into success group and failure group according to whether the treatment was successful or not. Spearman correlation analysis was used to analyze the correlation between cmin and AUC24/MIC of vancomycin, and one-way and multifactorial Logistic regression analyses were used to screen the independent risk factors for vancomycin treatment failure. RESULTS A total of 59 children were included, with 41 in the success group and 18 in the failure group. Compared with the failure group, AUC24/MIC of vancomycin was significantly higher in the success group (P=0.038), but there was no statistically significant difference in the cmin of the two groups (P>0.05); cmin of vancomycin was significantly positively correlated with AUC24/MIC (r=0.499, P<0.001), but it has a certain efficacy in predicting the achievement of the AUC24/MIC standard (≥400) (area under the receiver operator characteristic curve=0.696), with an optimal cutoff value of 6.05 mg/L determined by the Youden index. The efficacy of AUC24/ MIC in predicting treatment failure was superior to cmin (areas under the receiver operator characteristic curve were 0.671 vs. 0.523, P were 0.038 vs. 0.684), with higher sensitivity (83.3% vs. 66.7%). Hypoproteinemia and AUC24/MIC≤369.1 were independent risk factors for vancomycin treatment failure (P<0.05). The incidence of nephrotoxicity was 3.4%. CONCLUSIONS There is a significant positive correlation between cmin and AUC24/MIC of vancomycin in pediatric patients; hypoproteinemia and AUC24/MIC≤369.1 are independent risk factors for vancomycin treatment failure in children.

Ginsenoside Rg_2(GRg2) is a triterpenoid compound found in Panax notoginseng. This study explored its effects and mechanisms on diabetic retinopathy and angiogenesis. The study employed endothelial cell models induced by glucose or vascular endothelial growth factor(VEGF), the chorioallantoic membrane(CAM) model, the oxygen-induced retinopathy(OIR) mouse model, and the db/db mouse model to evaluate the therapeutic effects of GRg2 on diabetic retinopathy and angiogenesis. Transwell assays and endothelial tube formation experiments were conducted to assess cell migration and tube formation, while vascular area measurements were applied to detect angiogenesis. The impact of GRg2 on the retinal structure and function of db/db mice was evaluated through retinal thickness and electroretinogram(ERG) analyses. The study investigated the mechanisms of GRg2 by analyzing the activation of Yes-associated protein(YAP) and Toll-like receptors(TLRs) pathways. The results indicated that GRg2 significantly reduced cell migration numbers and tube formation lengths in vitro. In the CAM model, GRg2 exhibited a dose-dependent decrease in the vascular area ratio. In the OIR model, GRg2 notably decreased the avascular and neovascular areas, ameliorating retinal structural disarray. In the db/db mouse model, GRg2 increased the total retinal thickness and enhanced the amplitudes of the a-wave, b-wave, and oscillatory potentials(OPs) in the ERG, improving retinal structural disarray. Transcriptomic analysis revealed that the TLR signaling pathway was significantly down-regulated following YAP knockdown, with PCR results consistent with the transcriptome sequencing findings. Concurrently, GRg2 downregulated the expression of Toll-like receptor 4(TLR4), TNF receptor-associated factor 6(TRAF6), and nuclear factor-kappaB(NF-κB) proteins in high-glucose-induced endothelial cells. Collectively, GRg2 inhibits cell migration and tube formation and significantly reduces angiogenesis in CAM and OIR models, improving retinal structure and function in db/db mice, with its pharmacological mechanism likely involving the down-regulation of YAP expression.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

Adverse childhood experiences (ACEs) refer to traumatic events such as abuse and neglect experienced before the age of 18 years, which have negative impacts on an individual's physical and mental health. Studies have shown that ACEs not only increase the risk of health-harming behaviors such as smoking and alcohol abuse, but are also risk factors for depression and anxiety. The influence of ACEs on depression and anxiety exhibits type-specificity, cumulative effects, and temporal dynamics. The impact of ACE types on depression and anxiety varies across populations and genders, a dose-response relationship exists between the number of ACEs and depression/anxiety, and the phase, trajectory, and frequency of ACEs also significantly influence depression and anxiety. This article collected literature on ACEs and depression/anxiety from January 1995 to June 2024 by searching the CNKI and PubMed databases. It provides a comprehensive review of the associations between different ACEs types, quantities, categories, timing, trajectories, frequencies, and the risks of depression and anxiety, while also exploring the underlying mechanisms of these associations. The findings aim to offer references for the prevention and intervention of ACEs and the improvement of mental health.

OBJECTIVES:
To study the clinical characteristics of rashes induced by trimethoprim-sulfamethoxazole (TMP-SMZ) in children treated for pertussis and to inform safe medication practices.
METHODS:
A retrospective analysis was conducted on 238 children diagnosed with pertussis and treated with TMP-SMZ at Wuhu First People's Hospital from January to August 2024. The incidence and clinical features of rashes were summarized.
RESULTS:
Of 238 children, 34 (14.3%) developed rashes; 19 (55.9%) were boys, and the 5 to <10-year age group accounted for the highest proportion (70.6%, 24/34). A history of allergic disease was present in 50.0% (17/34). Rashes typically appeared on or after day 7 of therapy (82%, 28/34) and were predominantly erythematous or maculopapular eruptions (97%, 33/34); 71% (24/34) were pruritic. Fever occurred in 56% (19/34); among those who were tested for respiratory viruses, 77% (10/13) were positive for viruses such as rhinovirus and adenovirus. After discontinuation of TMP-SMZ, rashes resolved within 3 days in 97% (33/34) of patients (41% within 1 day; 56% within more than 1 but within 3 days). There was no significant difference in rash incidence between photoprotection and non-photoprotection groups (P>0.05).
CONCLUSIONS
TMP-SMZ for pertussis can induce rashes, particularly in children aged 5 to <10 years. The eruption is usually a pruritic erythematous or maculopapular rash, with over half of cases accompanied by fever and frequent concomitant viral infections. Most rashes resolve within 3 days after drug withdrawal. The potential association between the rash and sun exposure warrants further investigation.

BACKGROUND:
The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States.
METHODS:
A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed.
RESULTS:
During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms.
CONCLUSIONS
SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

OBJECTIVES:
To investigate the impact of high expression of transmembrane and coiled helix structural domain 1 (TMCO1) on prognosis of gastric cancer and the possible mechanisms.
METHODS:
TMCO1 expression in gastric cancer and its effect on gastric cancer progression and prognosis were analyzed using publicly available databases and clinical data of patients undergoing radical surgery in our hospital, and its possible biological functions were explored using KEGG and GO analyses. In gastric cancer HGC-27 cells, the effects of lentivirus-mediated TMCO1 overexpression and TMCO1 silencing on cell apoptosis, proliferation, invasion and migration were examined.
RESULTS:
TMCO1 expression was significantly elevated in gastric cancer tissues (P<0.05), and its high expression was positively correlated with cancer progression (P<0.001) and a lowered postoperative 5-year survival rate of the patients (P<0.05). Bioinformatic analyses suggested that TMCO1 may affect gastric cancer cell apoptosis via Wnt signaling. In HGC-27 cells, TMCO1 overexpression significantly promoted tumor cell proliferation, inhibited cell apoptosis, and enhanced cell migration and invasion, whereas TMCO1 silencing produced the opposite effects. Western blotting showed that β-catenin levels were significantly upregulated in TMCO1-overexpressing cells and downregulated in cells with TMCO1 silencing.
CONCLUSIONS
TMCO1 is overexpressed in gastric cancer tissues, and its high expression promotes gastric cancer progression and affects long-term prognosis of the patients possibly by activating the Wnt/ β-catenin signaling pathway to inhibit apoptosis of gastric cancer cells.

Objective:To compare the effects of high-power and conventional power atrial fibrillation ablation on intraoperative acute pulmonary vein isolation, postoperative troponin levels, and atrial fibrillation recurrence.Methods:A retrospective selection was conducted on 105 patients with paroxysmal atrial fibrillation admitted to the Baoding NO.1 Central Hospital from January 2017 to December 2020. According to different treatment methods, they were divided into a high-power ablation group of 52 cases and a conventional power ablation group of 53 cases. The intraoperative rate of single circle acute pulmonary vein isolation, the recovery of electrical conduction after acute pulmonary vein isolation, and the location and number of points that need to be added were compared between the two groups; At the same time, two groups were compared in terms of surgical time, ablation time, surgical radiation exposure time and radiation dose, intraoperative complications postoperative cardiac troponin levels at 12 hours, and recurrence of atrial fibrillation within 1 year after ablation.Results:The intraoperative single loop pulmonary vein isolation rate and postoperative troponin levels in the high-power atrial fibrillation ablation group were higher than those in the conventional atrial fibrillation ablation group (all P<0.05). The surgical time, ablation time, and the number of sites and points that need to be added during surgery were less than those in the conventional atrial fibrillation ablation group (all P<0.05). There was no statistically significant difference in the incidence of intraoperative complications and postoperative atrial fibrillation recurrence between the two groups (all P>0.05). Conclusions:High power atrial fibrillation ablation has a higher single loop acute pulmonary vein isolation rate, fewer patch sites and points, shorter surgical time, and greater ablation damage compared to conventional ablation, and the clinical efficacy of the two groups is similar after surgery.

Chinese Journal of School Health 2024;45(8):1115-1119
Objective:
To understand the prevalence of school bullying and the comorbidity of anxiety and depressive symptoms among middle school students and their association, so as to provide a basis for developing related intervention strategies.
Methods:
From September to December 2023, a multistage random cluster sampling was employed to select 107 851 middle school students across 104 counties in Anhui Province. The Center for Epidemiological Studies Depression Scale (CES-D) and the Generalized Anxiety Disorder-7 (GAD-7) Scale were used to assess depressive and anxiety symptoms. Logistic regression analysis was utilized to examine the correlations between experiences of school bullying and the comorbidity of anxiety and depressive symptoms.
Results:
The findings revealed that 2.80% of middle school students had experienced school bullying in the past 30 days. Additionally, 27.03% exhibited potential symptoms of depression, 8.94% showed signs of anxiety symptom, and the comorbidity rate of anxiety and depressive symptoms was 8.04%. Logistic regression analysis showed that statistically significant correlations were identified between experiences of school bullying and increased risks of depressive symptoms (OR=6.42, 95%CI=5.93-6.94, P<0.01), anxiety symptoms (OR=5.94, 95%CI=5.47-6.44, P<0.01), and their comorbidity (OR=6.38, 95%CI=5.88-6.93, P<0.01). Compared with those who did not suffer from school bullying, junior high school students, ordinary senior high school students, vocational senior high school students, boys and girls who suffered from school bullying all had increased risks of comorbidity of anxiety and depressive symptoms (OR=7.25, 5.55, 4.80, 6.42, 6.27, P<0.01).
Conclusions
The study underscores the significant impact of school bullying on increasing the risk of comorbidity of anxiety and depressive symptoms among middle school students. It is important to pay attention to the psychological health of bullied students and implement timely psychological intervention measures.
