Obesity， a global chronic disease， is associated with adipose tissue dysfunction， which is one of the contributing factors to obesity. The cyclic adenosine monophosphate （cAMP） signaling pathway， a key regulator of lipid metabolism， plays a pivotal role in obesity development. Various of traditional Chinese medicine monomers， such as flavonoids， lignans， phenols， and terpenoids， as well as traditional Chinese medicine compound formulas like Xiaoyao powder， Shengmai powder， and Zexie decoction， can maintain energy homeostasis， balance adipose tissue function， regulate glucose metabolism， improve insulin resistance， and suppress inflammatory responses through cAMP signaling pathway regulation， thereby intervening in lipid metabolism for obesity treatment. Although a substantial amount of basic research has preliminarily elucidated the potential mechanisms by which traditional Chinese medicine intervenes in obesity through the cAMP signaling pathway， clinical translational research remains inadequate. There is an urgent need for large-sample， high-quality randomized controlled trials to validate these findings.

Objective:To investigate the incidence of collateral circulation in high-risk patients with sleep apnea and stroke treated by continuous positive airway pressure （CPAP） ventilation and to analyze the influencing factors. Methods:A total of 152 patients diagnosed with obstructive sleep apnea-hypopnea syndrome （OSAHS） combined with acute ischemic stroke （AIS） who were admitted to our hospital from January 2020 to June 2022 were selected for this study. Based on the apnea-hypopnea index （AHI）, the patients were divided into three groups: mild （n=44）, moderate （n=72）, and severe （n=36）. After treatment, the patients were further classified into a group without collateral circulation （n=30） and a group with collateral circulation （n=26）, which included those with moderate collateral circulation （n=69） and good collateral circulation （n=27）. Clinical data across the different groups were compared, and multiple factor analysis was performed to identify factors affecting the occurrence of collateral circulation. Results:The AHI and IL-6 levels in the severe group were significantly higher than those in the mild and moderate groups, while the levels of NO and PO2 were significantly lower in the severe group compared to the mild and moderate groups, with statistically significant differences among the three groups （P<0.05）. After treatment, all groups showed improvement, and the proportion of patients with collateral circulation was 84.09% in the mild group, 81.94% in the moderate group, and 72.22% in the severe group. Significant differences in age, AHI, NIHSS, NO, MoCA, and MMSE scores were observed between the groups with and without collateral circulation （P<0.05）. In the group with collateral circulation, the scores for age, AHI, and NIHSS in the good collateral circulation subgroup were significantly lower than those in the poor collateral circulation and moderate collateral circulation subgroups, while the scores for NO, MoCA, and MMSE were significantly higher in the good collateral circulation subgroup. Multi-factor analysis revealed that age, AHI, and NIHSS were independent risk factors for collateral circulation, whereas NO, MoCA, and MMSE served as protective factors that were negatively correlated with collateral circulation. Classification tree model results indicated that AHI had the greatest influence on the occurrence of collateral circulation among the five influencing factors, demonstrating good predictive capability. Conclusion:Most high-risk patients with sleep apnea and stroke are likely to develop collateral circulation following continuous positive airway pressure ventilation. Factors such as age, AHI, NIHSS, NO, MoCA, and MMSE are important determinants affecting the occurrence of collateral circulation.

OBJECTIVE To get the current situation of healthcare associated infection(HAI)and implement targe-ted management through analyzing the trends of HAI incidence rate,the distribution of clinical departments,the sites of HAI and the composition of pathogens in a children's hospital in a five-year period.METHODS Data on HAI cases were collected from all inpatients in Children's Hospital of Soochow University from 2019 to 2023 through the real-time monitoring system of XINGLIN Healthcare acquired Infection Surveillance;Cochran-Armit-age test was used to check for the significant changes of distribution of HAI cases.RESULTS A total of 383,376 hospitalized patients were monitored from 2019 to 2023,of which HAI occurred on 6670 cases and 7209 case-times with an incidence rate of 1.74%and an incidence case rate of 1.88%.The top five departments of HAI inci-dence rates were cardiac,neonatal,surgical and pediatric intensive care unit and department of hematology.HAI mainly occurred in blood and alimentary system,upper and lower respiratory tract.A total of 2668 strains of path-ogenic bacteria were isolated,of which 1346 strains were gram-negative bacteria,1140 strains were gram-positive bacteria and 182 strains were fungi.The top three gram-negative bacteria were Klebsiella pneumoniae,Escherich-ia coli and Pseudomonas aeruginosa;the top three gram-negative pathogens were Streptococcus,Staphylococcus aureus and Staphylococcus epidermidis;and the top three fungi were Candida albicans,Candida parapsilosis and Candida tropicalis.CONCLUSIONS The HAI incidence rate of this hospital steadily declines in the past five years,however the same changes are not observed in the departments with high incidence of HAI.Attention should be paid to the raising bloodstream infections and detection rate of S.epidermidis.

Objective:To assess the levels of circRNA and N6-methyladenosine(m6A)methylation in hippocampal tissue of Alzheimer's disease(AD)mice and wild-type(WT)mice, and to explore the potential role of circRNA m6A methylation modification in the pathogenesis of Alzheimer's disease.Methods:Differentially expressed circular RNAs(circRNAs)in the hippocampal tissue of APPswe/PS1dE9(APP/PS1)double-transgenic Alzheimer's disease(AD)model mice and matched wild type mice were identified using RNA high-throughput sequencing(RNA-seq).Subsequently, Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were conducted on the source genes of these circRNAs.Validation of the RNA-seq results was performed using real-time quantitative PCR(qRT-PCR).Furthermore, the SRAMP website was utilized to predict potential m6A modification sites on the differentially expressed circRNAs.Finally, circRNAs with high confidence were validated and analyzed through methylated RNA immunoprecipitation-quantitative PCR(MeRIP-qPCR).Results:In comparison to the control group, 21 circRNAs exhibited differential expression in the APP/PS1 group, with 15 being up-regulated and 6 down-regulated.GO analysis revealed that the source genes of these differentially expressed circRNAs were primarily associated with synapse structure and function, while KEGG analysis indicated their involvement in the Hippo signaling pathway and Lipid metabolism.qRT-PCR results confirmed that the expression patterns of the differentially expressed circRNAs were consistent with the RNA-seq findings.Specifically, the expression of mmu-Bai3_0007 in the APP/PS1 group was significantly lower than that in the control group(0.033±0.002 vs.1.006±0.136, t=12.38, P<0.01), and the m6A methylation level of mmu-Bai3_0007 was also notably reduced in the APP/PS1 group compared to the control group(0.144±0.018 vs.0.431±0.087, t=5.62, P<0.01). Conclusions:The m6A methylation modification of Bai3circRNA could play a role in Alzheimer's disease by regulating the expression of Bai3 circRNA.

Objective:To explore the data distribution characteristics of hydrogen and methane breath test (HMBT) in Chinese population and to evaluate its applicability for diagnosing small intestinal bacterial overgrowth (SIBO) in Chinese population.Methods:HMBT data of 18 634 individuals who underwent health check-up nationwide from March 2019 to september 2022 were retrospectively collected, which included the levels of hydrogen and methane at 0, 30, 60, and 90 min. After quality control and data cleaning, the final valid sample size was 12 654 cases, comprising 7 146 SIBO-negative cases and 5 508 SIBO-positive cases. In order to exclude confounding factors such as oral hygiene, the 12 654 cases were divided into D0 and D1 dataset, when the 0 min-value of hydrogen and methane were both lower than the 30 min-value, the 0 min-value was taken as the baseline, and induded into the D0 dataset (5 556 cases), and other situations were induded into the D1 dataset (7 098 cases). There were 2 879 SIBO-negative cases and 2 659 SIBO-positive cases in D0 dataset, and 4 249 SIBO-negative cases and 2 849 SIBO-positive cases in D1 dataset. The hydrogen and methane level at each testing time point in the SIBO-negative and SIBO-positive individuals, the difference between the peak gas level at 90 min and the baseline, and the distribution of time points at which peak level occurred were analyzed. Independent-sample t test and Mann-Whitney U test were used for statistical analysis. Results:The overall SIBO positive rate was 43.53% (5 508/12 654). In SIBO-positive cases the hydrogen level at 0, 30, 60, and 90 min were 9.41×10 -6 (5.01×10 -6, 21.90×10 -6), 11.34×10 -6 (6.13×10 -6, 22.94×10 -6), 18.16×10 -6 (11.03×10 -6, 29.37×10 -6) and 29.59×10 -6 (20.12×10 -6, 43.36×10 -6), respectively, and methane level were 9.13×10 -6 (7.12×10 -6, 12.03×10 -6), 9.23×10 -6 (8.07×10 -6, 12.03×10 -6), 10.21×10 -6 (9.02×10 -6, 13.01×10 -6), and 12.03×10 -6 (10.01×10 -6, 14.11×10 -6), respectively, which were higher than those of SIBO-negative cases (6.04×10 -6 (3.10×10 -6, 11.08×10 -6), 6.04×10 -6 (3.21×10 -6, 10.06×10 -6), 6.95×10 -6 (4.03×10 -6, 11.01×10 -6), 8.96×10 -6 (5.01×10 -6, 13.91×10 -6); 8.04×10 -6 (7.02×10 -6, 10.00×10 -6), 8.03×10 -6 (7.03×10 -6, 9.95×10 -6), 8.04×10 -6 (7.03×10 -6, 10.00×10 -6) 8.98×10 -6 (7.12×10 -6, 10.03×10 -6)], and the differences were statistically significant ( U=1.41×10 7, 1.09×10 7, 6.66×10 6, 4.14×10 6, 1.51×10 7, 1.23×10 7, 1.02×10 7, 8.86×10 6; all P<0.001). In both D0 and D1 datasets, the increase in hydrogen and methane of SIBO positive subgroup were higher than those of SIBO negative subgroup (22.39×10 -6(14.82×10 -6, 33.37×10 -6) vs. 4.82×10 -6(1.96×10 -6, 7.85×10 -6), 20.61×10 -6(7.87×10 -6, 31.44×10 -6) vs. 3.25×10 -6(0.79×10 -6, 7.88×10 -6); 3.98×10 -6(2.87×10 -6, 6.87×10 -6) vs. 1.95×10 -6(0.98×10 -6, 2.99×10 -6), 2.95×10 -6(0.98×10 -6, 4.93×10 -6) vs. 0.98×10 -6(0.00×10 -6, 1.99×10 -6)), and the differences were statistically significant( U=7.24×10 6, 9.72×10 6, 5.74×10 6, 8.27×10 6; all P<0.001). In both D0 and D1 datasets, hydrogen and methane concentrations peaked at 90 min. Conclusion:HMBT can be used for non-invasive diagnosis of SIBO in Chinese population, and the differences in hydrogen and methane concentrations at 90 min of the test have critical value for SIBO diagnosis.

Objective:To systematically evaluate studies validating the performance of the Global Leadership Initiative on Malnutrition (GLIM) in diagnosing malnutrition.Methods:Seven Chinese and English databases including Embase, Web of Science (WOS), PubMed, CINAHL, Cochrane Library, SinoMed, CNKI, Wanfang Data, and VIP Database were searched for articles on the validation of GLIM criteria published between September 2018 and September 2024. Two researchers independently performed literature screening and data extraction. The concurrent and predictive validity of the criteria was analyzed.Results:A total of 136 papers were included for analysis. The GLIM criteria for diagnosing malnutrition had a sensitivity of 77%, a specificity of 87%, and an area under the curve (AUC) of 0.90. Malnutrition diagnosed by the GLIM criteria predicted prolonged hospital and intensive care unit (ICU) stays, increased readmission and complication rates (both overall and infectious), reduced survivals (median, overall, and disease-free), and increased in-hospital and follow-up mortalities. Both moderate and severe malnutrition predicted decreased overall survival. However, only three studies analyzed the impact of nutritional therapy on the clinical outcomes of malnourished patients.Conclusions:The GLIM criteria accurately differentiate malnutrition and are a valid predictive tool of clinical outcomes. However, the validity criteria in these validation studies were questionable, along with high methodological heterogeneity. Furthermore, there is a lack of studies validating the role of nutritional therapy in improving the clinical outcomes of malnourished patients.

Objective To explore the distribution characteristics and influencing factors of nasal colonized bacteria of healthcare workers(HCWs)in pediatric intensive care unit(PICU).Methods A cross-sectional study was con-ducted.Nasal swab specimens from 104 HCWs in the PICU of a hospital were collected for bacterial culture and an-timicrobial susceptibility testing.According to the identification and antimicrobial susceptibility testing results of strains,distribution characteristics of colonized bacteria was analyzed.Basic information of studied subjects were collected through questionnaire survey,and risk factors for colonized bacterial infection were conducted using logis-tic regression analysis.Results Among 104 specimens,colonized bacteria were detected from 66 specimens,with an overall detection rate of 63.46％.Gram-positive bacteria was mainly Staphylococcus aureus,with a detection rate of 34.62％(n=36),out of which methicillin-resistant Staphylococcus aureus(MRSA)accounted for 2.88％(n=3).Gram-negative bacteria was mainly Klebsiella spp.,with a detection rate of 21.15％(n=22).Multiva-riate logistic regression analysis showed that HCWs with junior professional titles(OR=11.400,95％CI:2.329-55.801,P=0.003)was an independent risk factor for Staphylococcus aureus colonization,and male(OR=4.260,95％CI:1.160-15.653,P=0.029)was an independent risk factor for Klebsiella spp.colonization.Conclusion Nasal cavity of HCWs in PICU has a high detection rate of colonized bacteria,with Staphylococcus aureus and Klebsiella spp.being the major colonized bacteria.

The prevalence of comorbidity of eating disorders(ED)and bipolar disorder(BD)is high,and patients with comorbid conditions often have a high risk of suicide and poor prognosis.Exploring the pathogenesis of BD comorbid with ED is of great significance for improving clinical efficacy and adverse prognosis in patients.The mechanisms underlying BD comorbid ED remain unclear,involving multifaceted neurobiological factors such as serotonin system dysfunction,dopamine reward pathway disruption,abnormal immune system activation,fluctuations in sex hormone levels,and functional and structural abnormalities in brain regions associated with emotional control and reward system pathways.Therefore,this article provides ideas for the research direction of BD comorbid with ED by analyzing the roles of genetic metabolism,neurobiochemistry,immune,and imaging changes in the comorbidity mechanism.
