Recently, the World Health Organization (WHO) R&D Blueprint for Epidemics released the 2024 priority pathogen list. Over 200 scientists around the world evaluated the evidences of transmissions, virulences of 1 652 pathogens and the availability of medical countermeasures in two years. Finally, 33 pathogens that could potentially cause the next pandemic were included in the priority pathogen list. This list introduces the scientific framework of "family-priority pathogen-prototype pathogen", emphasizing the importance of studying entire pathogen family rather than specific pathogen. The list can be used to guide and coordinate the research and development of medical countermeasures, including vaccine, blood product, antibody, antimicrobial or antiviral drug, diagnostic test, and personal protective equipment, thereby improving the global rapid response to unknown infectious disease threats. This article summarizes the scientific background and main contents of the WHO priority pathogen list and the enlightenment for pandemic preparedness in the development of medical countermeasures in China to provide reference for the disease prevention and control in China.

Objective·To evaluate the effects of normally positioned flap(NPF)and coronally advanced flap(CAF)techniques on clinical results after epulis excision.Methods·A total of 55 patients with epulis who visited the Department of Periodontology,Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from August 2022 to December 2023 were included.The patients were divided into the NPF group and the CAF group.After epulis excision,the surgical area was closed using NPF or CAF technique.The following parameters were recorded:baseline epulis width(EW)and epulis height(EH);papilla width(PW)and papilla height(PH)at 6 months post-surgery;probing depth(PD),attachment loss(AL),and keratinized gingiva width(KGW)at both baseline and 6 months post-surgery.The esthetic outcomes were evaluated using a visual analog scale(VAS)by 2 periodontal specialists.t test was used to compare the differences in periodontal indices between baseline and 6 months post-surgery,as well as between the 2 flap techniques.Results·At 6 months post-surgery,PD of the CAF group was(1.68±0.79)mm,significantly lower than at baseline(P<0.001),but not significantly different from that in the NPF group(P=0.365);the AL in the CAF group was(1.26±1.18)mm,not significantly different from baseline(P=0.746),but significantly lower than in the NPF group(P<0.001).At 6 months post-surgery,PH of the CAF group was(3.74±0.62)mm,significantly higher than that in the NPF group(P<0.001),and the VAS score of the CAF group was significantly higher than that of the NPF group(P<0.001).Conclusion·Compared with NPF,CAF could effectively improve post-surgical KGW and reduce AL,which could prevent periodontal soft tissue defects,and improve esthetic outcome after epulis excision.

Herpes zoster (HZ) and its complications remain one of the major public health problems threatening human health. Four HZ vaccines are currently licensed for commercial use worldwide, while novel HZ vaccine candidates based on diverse technological platforms are in different stages of development. Enhancing public understanding of the effectiveness and safety of HZ vaccines is particularly crucial for increasing vaccine coverage and reducing vaccine hesitancy. This article introduces the overview of licensed HZ vaccines with a focus on elucidating the effectiveness and safety of HZ vaccines in immunocompetent and immunocompromised populations, in order to provide a scientific basis for the deployment of HZ vaccination.

Hand, foot and mouth disease (HFMD) is a common infectious disease among children, and has emerged as a substantial global public health concern, particularly in the Asia-Pacific region. It has a serious impact on children′s health and imposes a significant disease burden on families and society. Currently, there are three globally available HFMD vaccines (all of them are EV71 inactivated vaccine), which were first approved and marketed in China in 2016. Real-world studies have shown a decrease in the incidence, severity, and mortality rate of EV71-related HFMD, providing evidence of its effectiveness. Additionally, related data have indicated a significant change in the pathogen spectrum of HFMD in China in the post-vaccine era. This article aims to provide a comprehensive review of the safety, effectiveness and immune-persistence data of EV71 vaccine acquired through real-world studies.

Stapled peptides with significantly enhanced pharmacological profiles have emerged as promising therapeutic molecules due to their remarkable resistance to proteolysis and performance to penetrate cells. The all-hydrocarbon peptide stapling technique has already widely adopted with great success, yielding numerous potent peptide-based molecules. Based on our prior efforts, we conceived and prepared a double-stapled peptide in this study, termed FRNC-1, which effectively attenuated the bone resorption capacity of mature osteoclasts in vitro through specific inhibition of phosphorylated GSK-3β. The double-stapled peptide FRNC-1 displayed notably improved helical contents and resistance to proteolysis than its linear form. Additionally, FRNC-1 effectively prevented osteoclast activation and improved bone density for ovariectomized (OVX) mice after intravenous injection and importantly, after oral (intragastric) administration. The double-stapled peptide FRNC-1 is the first orally effective peptide that has been validated to date as a therapeutic candidate for postmenopausal osteoporosis (PMOP).
