The incidence of cardiovascular diseases(CVD)has been increasing year by year,with atherosclerosis(As)being the leading cause in terms of both incidnce and mortality for CVD in China.Traditional theories suggest that the pathogenesis of atherosclerotic CVD is associated with endothelial dysfunction and inflammatory responses caused by the accumulation of oxidized low density lipoprotein(ox-LDL).However,recent studies have demonstrated that perivascular adipose tissue(PVAT)can positively influence the occurrence and development of CVD through the vascular adventitia pathway.This article reviews the connection between PVAT and CVD,effective pathways for promoting CVD improve-ment,and the regulatory role of AMP-activated protein kinase(AMPK)on PVAT,aiming to explore effective intervention targets for CVD.

Objective To explore the protective effects of pretreatment with the Mongolian medicine Jiruhen Gurigumu-7(JG-7)and Guangzao Sanwei Tang(GZ-3)on myocardial ischemia-reperfusion injury(MIRI)in mice.Methods 60 male C57BL/6J mice were randomly divided into sham operation(Sham)group,model(Model)group,compound danshen drip pill(CDDP)positive control group,JG-7 group,GZ-3 group,and 12 mice in each group to establish the MIRI model,and the H9C2 cells were randomly divided into Control(normoxic)group,H/R(hypoxia 6 h reoxygenation 14 h)group,H/R+JG-7 group,H/R+GZ-3 group.The mice in each group were tested for cardiac function indexes after 30 min of ischemia,24 h and 7 d of reperfusion,TTC staining to detect infarct area after 24 h of MIRI,HE staining to detect myocardial tissue structure and cellular morphology after 24 h of MIRI,TUNEL apoptosis kit to detect apoptosis of myocardial cells after 24 h of MIRI,Masson staining to detect myocardial fibrosis after 7 d of MIRI.Blood was taken from the abdominal aorta,serum was separated,and the indexes after oxidative stress of MIRI were detected in each group of mice,and the survival rate of H9C2 cells after H/R was detected in each group by CCK-8 method.Results The results of TTC showed that JG-7 and GZ-3 reduced the infarct area after 24 h of MIRI in mice.ELISA and kit assays proved that JG-7 and GZ-3 reduced creatine phosphokinase isoenzyme(Creatinekinase-MB,CK-MB),Lactic dehydrogenase(LDH),malondialdehyde(MDA)levels,and increased superoxide dismutase(SOD)levels.HE staining showed that JG-7 and GZ-3 improved myocardial pathology after MIRI 24 h.The results of TUNEL apoptosis assay showed that JG-7 and GZ-3 improved apoptosis in myocardial tissues 24 h after MIRI.Masson staining results showed that JG-7 and GZ-3 could reduce the area of myocardial tissue fibrosis after MIRI 7 d.CCK-8 assay results showed that JG-7 and GZ-3 could improve the cell survival rate after H/R in H9C2 cells.Conclusion Pre-treatment with Mongolian medicine Jiruhen Gurigumu-7 and Guangzao Sanwei Tang can reduce the damage caused after ischemia-reperfusion(I/R),decrease the area of myocardial infarction and fibrosis after I/R in mice,and protect the heart.

Objective:To investigate the differences in protein profile expression in serum samples from children with corona virus disease 2019（COVID-19）related encephalopathy and to explore the underlying mechanisms.Methods:From December 1,2022 to January 31,2023,28 children with COVID-19 who were admitted to the Department of Pediatric Intensive Medicine at Shandong Provincial Hospital Affiliated to Shandong First Medical University were collected,including 21 patients with encephalopathy(COVID-19 with encephalopathy group) and seven patients without encephalopathy(COVID-19 without encephalopathy group).Three children from each group were selected for serum proteomic analysis using tandem mass spectrometry labeling proteomics technology.Proteins were considered significantly different if the fold change was >1.2 or <0.8，with P<0.05.Bioinformatics analysis，including Gene Ontology and Kyoto Encyclopedia of Genes and Genomes Pathway Enrichment were performed on differentially expressed proteins.Protein-protein interaction networks were analyzed using the STRING database.Selected proteins were further validated by enzyme-linked immunosorbert assay. Results:A total of 41 differentially expressed proteins were identified between the two groups.Among these，14 proteins were upregulated and 27 proteins were downregulated in COVID-19 patients with encephalopathy compared to those without encephalopathy.Bioinformatics analysis revealed that these proteins were primarily enriched in critical signaling pathways，including complement and coagulation regulation，neutrophil degranulation and activation，and platelet degranulation.Enzyme-linked immunosorbert assay validation confirmed significant differences in key coagulation-regulating proteins(von willebrand factor upregulated，serpin family F member 2 downregulated in COVID-19 patients with encephalopatly）between the two groups.Conclusion:Coagulation dysfunction may play a role in the development of COVID-19 associated encephalopathy in children，providing valuable insights for future research.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective:To explore the application effect of ketamine and remifentanil in pediatric ophthalmic laryngeal mask placement general anesthesia surgery.Methods:A total of 68 children who underwent ophthalmic laryngeal mask placement general anesthesia surgery in Zhangjiakou Fourth Hospital from July 2020 to May 2023 were prospectively selected and they were randomly separated into a ketamine group (34 cases, anesthesia with ketamine combined with propofol) and a remifentanil group (34 cases, propofol combined with remifentanil). The mean arterial pressure (MAP), heart rate (HR), and blood oxygen saturation (SpO 2) of the two groups were compared at before anesthesia (T 1), after anesthesia (T 2), intraoperative 5 min (T 3), intraoperative 20 min (T 4) and after surgery (T 5). Meantime, the satisfaction with anesthesia among the surgeons, perioperative adverse reactions, surgical duration, recovery time and time to transfer out of the postanesthesia care unit (PACU) were compared between the two groups. Results:The MAP and HR of the remifentanil group at T 2 to T 4 were lower than before anesthesia, MAP: (72.83 ± 8.25), (74.18 ± 8.57) and (74.49 ± 9.13) mmHg (1 mmHg = 0.133 kPa) vs. (76.26 ± 9.51) mmHg; HR: (83.21 ± 6.63), (85.18 ± 7.06) and (86.81 ± 7.53) times/min vs. (89.72 ± 7.46) times/min ( P< 0.05), while the MAP and HR of the ketamine group at T 2 to T 5 were higher than before anesthesia, MAP: (81.67 ± 9.31), (85.06 ± 11.25), (86.34 ± 11.56) and (87.51 ± 9.30) mmHg vs. (77.58 ± 10.22) mmHg; HR: (95.04 ± 9.78), (97.60 ± 8.24), (98.64 ± 10.47) and (100.21 ± 8.56) times/min vs. (88.53 ± 9.15) times/min ( P<0.05), there was no difference in SpO 2 in the two groups between T 2 to T 5 and T 1 ( P>0.05), while the MAP and HR of the remifentanil group were lower than those of the ketamine group at T 2 to T 5, MAP: (72.83 ± 8.25) mmHg vs. (81.67 ± 9.31) mmHg, (74.18 ± 8.57) mmHg vs. (85.06 ± 11.25) mmHg, (74.49 ± 9.13) mmHg vs. (86.34 ± 11.56) mmHg, (75.38 ± 8.96) mmHg vs. (87.51 ± 9.30) mmHg; HR: (83.21 ± 6.63) times/min vs. (95.04 ± 9.78) times/min, (85.18 ± 7.06) times/min vs. (97.60 ± 8.24) times/min, (86.81 ± 7.53) times/min vs. (98.64 ± 10.47) times/min, (88.45 ± 9.51) times/min vs. (100.21 ± 8.56) times/min ( P<0.05), there was no difference in T 2 to T 5 SpO 2 between the two groups ( P>0.05); the satisfaction with anesthesia among the surgeons in the remifentanil group was higher than that in the ketamine group: 82.35% (28/34) vs. 58.82% (20/34), and the incidence of perioperative adverse reactions was lower than that in the ketamine group: 11.76% (4/34) vs. 32.35% (11/34); the surgical time, recovery time, and time to transfer out of PACU in the remifentanil group were all shorter than those in the ketamine group: (48.26 ± 9.54) min vs. (56.32 ± 11.86) min, (13.84 ± 4.12) min vs. (18.36 ± 5.08) min, (21.50 ± 6.14) min vs. (27.98 ± 8.62) min ( P<0.05). Conclusions:Compared with ketamine, remifentanil has a better effect in pediatric ophthalmic laryngeal mask placement general anesthesia surgery, which is more conducive to stabilizing the cardiovascular system during surgery, reducing the occurrence of adverse reactions such as perioperative restlessness, and shortening the surgical time and recovery time.
