Objective:To explore the application value of real-time shear wave elastography(SWE)and ultrafast pulse wave velocity(UFPWV)techniques in assessing carotid artery stiffness of patients with gouty arthritis(GA).Methods:A total of 80 GA patients admitted to the First People's Hospital of Yibin from August 2022 to July 2023 were selected as GA group.Among of them,24 cases combined with bone erosion who were confirmed by imaging examination,and 56 cases did not combine with bone erosion.In addition,a total of 40 healthy individuals,who underwent physical examinations in our hospital during the same period,were selected as the healthy control group.SWE and UFPWV were used to detect the maximum,minimum and mean values of Young's modulus values of the vessel wall of common carotid artery,and the pulse wave velocity at the beginning of systole(PWVBS)and pulse wave velocity at the end of systole(PWVES)of the vessel wall of common carotid artery of all subjects,and to assess the hardness of circumferential and longitudinal vessel wall of common carotid artery of them.The differences in Young's modulus values,PWVBS and PWVES between two groups were compared.And then,the correlations between bone erosion and Young's modulus values,PWVBS,PWVES of GA patients were further analyzed.Results:The maximum,minimum,mean values,PWVBS and PWVES in the GA group were respectively(78.80±12.38)kPa,(57.83±7.42)kPa,(67.67±8.38)kPa,(7.06±0.59)m/s and(9.50±0.63)m/s,which were significantly higher than those in the healthy control group(t=11.066,8.216,11.751,14.159,19.118,P＜0.05).The maximum,minimum,mean values,PWVBS and PWVES of GA patients with bone erosion were respectively(82.95±6.37)kPa,(59.59±5.29)kPa,(72.18±7.62)kPa,(7.37±0.43)m/s,(10.43±0.47)m/s,which were significantly higher than those[(77.01±5.32)kPa,(57.08±4.73)kPa,(65.73±4.54)kPa,(6.92±0.39)m/s and(9.10±0.41)m/s]of GA patients without bone erosion,the differences were significant(t=4.309,2.099,4.699,4.586,12.720,P＜0.05).Spearman correlation analysis showed that there was significant correlations between maximum,minimum,mean values,PWVBS,PWVES and the combined bone erosion in GA patients(r=0.602,0.421,0.682,0.647,0.732,P＜0.05).Conclusion:SWE and UFPEV techniques can evaluate the hardness of vascular wall of GA patients,and the hardness of circumferential and longitudinal vessel wall of common carotid artery of GA patient is higher than that of healthy person,and the hardness of circumferential and longitudinal vessel wall of common carotid artery of GA patient with bone erosion is higher.

Nanomaterials, with the advantages of unique microstructure, have been widely used in the fields of material manufacturing, microelectronics and computer technology, medicine and health, environment and energy. Compared with traditional hemostatic materials, nanomaterials can improve the bioavailability and stability of traditional hemostatic drugs to a certain extent, enhance the controlled and targeted release of drugs, which lay a good foundation for the development of new-style modern hemostatic nanomaterials. This paper reviews the advanced design and application progress of various nanomaterials in hemostasis, such as liposomes, nanoparticles, self-assembled nano peptides, nanofibers, etc. Finally, the challenges and prospects of hemostatic nanomaterials are briefly described.

Novel Coronavirus Pneumonia (NCP) is a class B infectious disease, which is prevented and controlled according to class A infectious diseases. Recently, children′s NCP cases have gradually increased, and children′s fever outpatient department has become the first strategic pass to stop the epidemic. Strengthening the management of the fever diagnosis process is very important for early detection of suspected children, early isolation, early treatment and prevention of cross-infection. This article proposes prevention and control strategies for fever diagnosis, optimizes processes, prevents cross-infection, health protection and disinfection of medical staff, based on the relevant diagnosis, treatment, prevention and control programs of the National Health and Health Commission and on the diagnosis and treatment experience of experts in various provinces and cities. The present guidance summarizes current strategies on pre-diagnosis; triage, diagnosis, treatment, and prevention of 2019-nCoV infection in common fever, suspected and confirmed children, which provide practical suggestions on strengthening the management processes of children′s fever in outpatient department during the novel coronavirus pneumonia epidemic period.

To determine the impact of IL-23 knockdown by RNA interference on the development and severity of ovalbumin (OVA)-induced asthmatic inflammation, and the potential mechanisms in mice, the IL-23-specific RNAi-expressing pSRZsi-IL-23p19 plasmid was constructed and inhaled into OVA-sensitized mice before each challenge, as compared with that of control mice treated with alum or budesonide. Inhalation of the pSRZsi-IL-23p19, significantly reduced the levels of OVA-challenge induced IL-23 in the lung tissues by nearly 75%, determined by RT-PCR. In addition, knockdown of IL-23 expression dramatically reduced the numbers of eosinophils and neutrophils in BALF and mitigated inflammation in the lungs of asthmatic mice. Furthermore, knockdown of IL-23 expression significantly decreased the levels of serum IgE, IL-23, IL-17, and IL-4, but not IFNgamma, and its anti-inflammatory effects were similar to or better than that of treatment with budesonide in asthmatic mice. Our data support the notion that IL-23 and associated Th17 responses contribute to the pathogenic process of bronchial asthma. Knockdown of IL-23 by RNAi effectively inhibits asthmatic inflammation, which is associated with mitigating the production of IL-17 and IL-4 in asthmatic mice.
