Background The thirteen-valent pneumococcal conjugate vaccine(PCV13)is not included in the national immu-nization program and is administered voluntarily with informed consent in China.In preparation for assessing the impact of pilot introduction in Hainan Province,we conducted a carriage study among children under 5 years of age from four locations in Hainan Province,China.Methods From March to June 2022,nasopharyngeal(NP)swabs,collected from healthy children aged younger than 59 months who lived in the 4 different locations(Haikou,Wanning,Baisha and Qiongzhong)in Hainan Province,were tested for pneumococcus using conventional culture.Pneumococcal isolates were serotyped using the Quel-lung reaction.Risk factors associated with pneumococcal colonization were assessed using univariate analysis and multivariable logistic regression adjusting for age,daycare attendance and other factors.Results Pneumococcus was isolated in 710(30.4%)of the 2333 children enrolled.Of 737 pneumococci,29 serotypes were identifed;60.9%were PCV13 serotypes;the most common vaccine serotypes were 6B(20.4%),19F(13.0%),6A(11.9%)and 23F(6.1%);and the most common nonvaccine serotypes were 23A(12.9%),34(6.1%)and nontypeable(NT)pneumococci(5.6%).Children vaccinated with PCV13 had lower carriage(17.7%vs 32.5%;P=0.0001)and fewer PCV13 serotypes(41.9%vs 62.7%;P=0.0017)compared to unimmunized children.After adjustment,NP carriage Was higher among children attending daycare(aOR=2.3,95%CI:1.7-3.2),living in rural areas(aOR=1.4,95%CI:1.1-1.8),living with siblings(aOR=1.3,95%CI:1.0-1.6)and whose mothers had completed senior high/technical sec-ondary school(aOR=1.5,95%CI:1.1-2.0).In contrast,completion of 3-4 doses of PCV13 were associated with a lower carriage rate(aOR=0.6,95%CI:0.4-0.9).Conclusions We established the baseline of pneumococcal carriage,serotype distribution and PCV13 immuni-zation rates among healthy children under 5 years of age in Hainan Province,prior to the introduction of PCV13 into the national immunization program.The high proport

Do nocturnal birds use acoustic and visual cues to avoid predation by bats?

Integrative Zoology 2024年第3期19卷 524-537页

Anti-predation strategies are critical to animal survival and are fundamental to deciphering predator–prey interactions.As an important defense strategy,sensory predator detection(such as through acoustic and visual cues)enables animals to assess predation risk and execute predator-avoidance behavior;however,there are limited studies on the anti-predation behavior of nocturnal animals.The prey of bats provides an excellent representative system for examining the anti-predation behavior of nocturnal animals.Here,we broadcasted different types of echolocation calls of the bird-eating bat Ia io to two wild passerine birds,namely,Zosterops japonicus and Sinosuthora webbiana,that are preyed upon by I.io,and presented the birds with individual bats under different light intensities.The results showed that both bird species were able to perceive the low-frequency audible portion of the bats’echolocation calls;however,they did not exhibit escape responses to the acoustic stimuli.In the dark and under moonlit conditions,both bird species were unable to respond to active bats at close range and the birds only exhibited evasive flight behavior when bats approached or touched them.These results suggest that nocturnal passerine birds may not be able to use acoustic or visual cues to detect bats and adopt evasive maneuvers to avoid predation.This work suggests that bat predation pressure may not elicit primary predator-avoidance responses in nocturnal passerine birds.The results provide new insights into the anti-predation behavior of nocturnal animals.

Optimal scheduling of renewable energy sources and building energy systems serves as a pivotal strategy for achieving zero carbon emission.However,the coordination of zero carbon building energy systems(ZCBS) is still challenging due to the complicated interactions among multi-energy hybrid storage and the complex coordination between seasonal and daily scheduling.Therefore,this study develops a coordination scheduling approach for ZCBS.An operation model and a seasonal-daily scheduling approach are developed to optimize the operation of hydrogen,geothermal,and water storage devices.The performance of the developed method is demonstrated using numerical case studies.The results show that the ZCBS can be achieved by using renewable energy sources with the system flexibility provided by hydrogen,geothermal,and water storage devices.It is also found that the developed scheduling approach reduces operation costs by more than 43.4%under the same device capacity,compared with existing scheduling approaches.

Chinese Medical Journal 2024年第2期137卷 190-199页

Background:Acute-on-chronic liver failure(ACLF)is a severe liver disease with complex pathogenesis.Clinical hypoglycemia is common in patients with ACLF and often predicts a worse prognosis.Accumulating evidence suggests that glucose metabolic disturbance,especially gluconeogenesis dysfunction,plays a critical role in the disease progression of ACLF.Lon protease-1(LONP1)is a novel mediator of energy and glucose metabolism.However,whether gluconeogenesis is a potential mechanism through which LONP1 modulates ACLF remains unknown.Methods:In this study,we collected liver tissues from ACLF patients,established an ACLF mouse model with carbon tetrachloride(CCl 4),lipopolysaccharide(LPS),and D-galactose(D-gal),and constructed an in vitro hypoxia and hyperammonemia-triggered hepatocyte injury model.LONP1 overexpression and knockdown adenovirus were used to assess the protective effect of LONP1 on liver injury and gluconeogenesis regulation.Liver histopathology,biochemical index,mitochondrial morphology,cell viability and apoptosis,and the expression and activity of key gluconeogenic enzymes were detected to explore the underlying protective mechanisms of LONP1 in ACLF.Results:We found that LONP1 and the expressions of gluconeogenic enzymes were downregulated in clinical ACLF liver tissues.Furthermore,LONP1 overexpression remarkably attenuated liver injury,which was characterized by improved liver histopathological lesions and decreased serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in ACLF mice.Moreover,mitochondrial morphology was improved upon overexpression of LONP1.Meanwhile,the expression and activity of the key gluconeogenic enzymes were restored by LONP1 overexpression.Similarly,the hepatoprotective effect was also observed in the hepatocyte injury model,as evidenced by improved cell viability,reduced cell apoptosis,and improved gluconeogenesis level and activity,while LONP1 knockdown worsened liver injury and gluconeogenesis disorders.Conclusion:We demonstrated that gluconeogenesis dysfunc

Macrophages,a heterogeneous population of innate immune cells,exhibit remarkable plasticity and play pivotal roles in coordinating immune responses and maintaining tissue homeostasis within the context of metabolic diseases.The activation of inflammatory macrophages in obese adipose tissue leads to detrimental effects,inducing insulin resistance through increased inflammation,impaired thermogenesis,and adipose tissue fibrosis.Meanwhile,adipose tissue macrophages also play a beneficial role in maintaining adipose tissue homeostasis by regulating angiogenesis,facilitating the clearance of dead adipocytes,and promoting mitochondrial transfer.Exploring the heterogeneity of macrophages in obese adipose tissue is crucial for unraveling the pathogenesis of obesity and holds significant potential for targeted therapeutic interventions.Recently,the dual effects and some potential regulatory mechanisms of macrophages in adipose tissue have been elucidated using single-cell technology.In this review,we present a comprehensive overview of the intricate activation mechanisms and diverse functions of macrophages in adipose tissue during obesity,as well as explore the potential of drug delivery systems targeting macrophages,aiming to enhance the understanding of current regulatory mechanisms that may be potentially targeted for treating obesity or metabolic diseases.
