Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

ObjectiveTo investigate the incidence of stroke in patients with type 2 diabetes mellitus (T2DM) in the community of Shanghai, and to explore its influencing factors. MethodsA two-way cohort study was used to observe the incidence of stroke in a dynamic cohort of14 743 community-based T2DM patients who were enrolled for management from January 2016 to December 2018 in Hongkou District, Shanghai. All the research subjects were followed up for 3 years to observe the stroke occurrence. Outcome events were retrospectively collected from the Shanghai Stroke and Acute Myocardial Infarction Registry Reporting Information System and the Cause of Death Registry System, and information on stroke onset and verification of past medical history were collected by family physicians through clinic follow-up, home follow-up, and telephone follow-up. Cox proportional hazards model was used to identify the risk factors of stroke in TDM2 patients, and the hazard ratio (HR) and its 95% confidence interval (CI) were calculated. ResultsAfter a mean follow up of 3.5 years, the standardized incidence of stroke in patients with T2DM was 8.65‰, and the risk of standardized incidence was 3.50 (95%CI: 3.26‒3.77) compared with that of the total national population. Cox proportional hazards regression analysis showed that age (HR=1.18, 95%CI: 1.13‒1.23), being female (HR=1.14, 95%CI: 1.01‒1.29), physical activity <600 metabolic equivalent (MET)·min·week^-1 (HR=1.24, 95%CI: 1.06‒1.44), substandard of HbA1c control (HR=1.16, 95%CI: 1.03‒1.30), occasional smoker(HR=1.23, 95%CI: 1.04‒1.45), and those who took insulin therapy (HR=1.36, 95%CI: 1.11‒1.66) were associated with an increased risk of stroke, while those received contracted services from family doctors were associated with a decreased risk of stroke(HR=0.78, 95%CI: 0.71‒0.88). ConclusionCommunity T2DM population in Shanghai has a high risk of stroke. It is necessary to continue to explore the positive role of family doctor contract service management model, strengthen individualized exercise, smoking cessation and other lifestyle interventions, and strictly control blood glucose as soon as one can to delay or avoid the occurrence of complications.

Objective:To analyze the epidemiological and clinical characteristics of influenza A/B virus (IAV/IBV) infection in children aged 0-4 years in Jining city from 2022 to 2024.Methods:A retrospective analysis was conducted on the data of 3 106 influenza affected children who visited two monitoring outpost hospitals in Jining city from January 2022 to January 2024. They were separated into two groups based on the type of virus infection: IAV group (n=1 829) and IBV group (n=1 277). Two groups were compared for general information, epidemiological characteristics, and laboratory test indicators.Result:The majority of influenza patients were boys (59.01%) and 1-4 years old (63.01%), with peak body temperature mainly ranging from 37.8 to 38.9 ℃ (59.30%). Coughing (69.00%) and runny nose (66.03%) were the main manifestations. The onset season was concentrated in winter (42.43%) and spring (40.44%), and the exposure target were family members (51.90%), and the proportion of influenza vaccine injections (20.90%) was relatively low. The proportions of visit time≤3 d, peak body temperature≥39.0 ℃, myocardial damage, liver function damage, white blood cell count (WBC) of 4-10×10 9/L, and neutrophil percentage (N)>70% in the IAV group were higher than those in the IBV group ( P<0.05). The proportions of preschool children and WBC>10×10 9/L in the IBV group were higher than those in the IAV group ( P<0.05). Conclusions:Children aged 0-4 years who are infected with IAV in Jining City are more common in terms of high fever, early medical attention, impaired heart and liver function, normal WBC, and abnormal N elevation compared to those infected with IBV. However, children aged 0-4 who are infected with IBV have abnormally high WBC and are more common in daycare.

OBJECTIVE: To review the role and research progress of mechanotransduction signaling pathway in distraction osteogenesis, so as to provide theoretical basis and reference for clinical treatment. METHODS: The role and research progress of mechanotransduction signaling pathway in distraction osteogenesis were summarized by extensive review of relevant literature at home and abroad. RESULTS: The mechanotransduction signaling pathway plays a central role of "sensation-transformation-execution" in distraction osteogenesis, and activates a series of molecular mechanisms to promote the regeneration and remodeling of bone tissue by integrating external mechanical signals. Mechanical stimuli are converted into mechanotransduction signals through the perception of integrins, Piezo1 ion channels and bone cell networks. Activate downstream molecules are transduce through signal pathways such as Wnt/β-catenin, transforming growth factor β/bone morphogenetic protein-Smad, mitogen-activated protein kinase, protein kinase Hippo-Yes-associated protein/transcriptional coactivator with PDZ-binding motif, and phosphatidylinositol 3-kinase/ protein kinase B, so as to achieve the effects of promoting osteoblasts proliferation, accelerating endochondral ossification, regulating bone resorption and the like, thereby promoting the regeneration of new bone in the distraction area. The study of mechanotransduction signaling pathways in distraction osteogenesis is expected to optimize the mechanical parameters of distraction osteogenesis and provide targeted intervention strategies for accelerating new bone regeneration and mineralization in the distraction zone. However, the specific mechanism of mechanotransduction signaling pathway in distraction osteogenesis remains to be further elucidated, and artificial intelligence and multi-omics analysis may be the future development direction of mechanotransduction signaling pathway. CONCLUSION In distraction osteogenesis, mechanotransduction signal transduction is the core mechanism of bone regeneration in the distraction zone, which regulates cell behavior and tissue regeneration by converting mechanical stimulation into biochemical signals.

Objective:To explore the impact of early and late antibody-mediated rejection (AMR) on treatment options and allograft outcomes after kidney transplantation (KT).Methods:From January 2013 to December 2022, the study retrospectively enrolled 141 KT allograft recipients receiving allograft biopsy and diagnosed as AMR according to the Banff 2019 criteria. Recipients with a diagnosis of AMR within 30 days post-KT were classified into early AMR group (n=19) while the remainders assigned as late AMR group (n=122). The outcome endpoints included recipient survival rate, death-censored graft survival rate, follow-up estimated glomerular filtration rate (eGFR) and immunodominant donor-specific antibody (DSA) intensity. Wilcoxon's test was utilized for assessing the differences in eGFR and DSA intensity while Kaplan-Meier curve and Log-rank test were employed for evaluating graft survival impact. Treatment regimens for AMR were collected and categorized.Results:The median follow-up duration was 2.6(1.2, 5.2) year. No graft failure was noted in early AMR group while 44 recipients in late AMR group experienced graft failure, with 34 cases (77.2%) due to AMR progression. The 5-year death-censored graft survival rate was significantly better in early AMR group than that in late AMR group [100% vs 60.1%(50.5%, 71.6%), P=0.002]. The one-year change in eGFR for early AMR group was significantly superior to that of late AMR group [19.3(-2.6, 38.1) vs -3.3(-14.0, 5.4), P=0.001]. One-year mean fluorescent intensity (MFI) of early AMR group was 1 158(401.5, 3 126.5). It was significantly lower than that when diagnosed with early AMR [3 120.5(2 392.8, 9 340.0)] and one-year MFI of late AMR group [8 094(2 251.5, 13 560.5)] ( P=0.005, P<0.001). Early AMR group primarily received standard treatment (3/19, 15.8%) and regimens centered on rituximab and/or bortezomib (7/19, 43.8%). Late AMR group mainly received standard (16/122, 13.1%) or intensified regimens (9/122, 7.4%) and regimens focused upon rituximab and/or bortezomib (32/122, 26.2%) and MP monotherapy (21/122, 17.2%). Conclusion:The outcome for early AMR is significantly better than that for late AMR. For early AMR, early and robust immunosuppression is recommended. For late AMR, early detection and timely treatment are crucial and individualized strategies should be implemented.

bstract: Objective To elucidate the distribution characteristics of mosquito species and the population genetic diversity of important mosquito species in the Wuyi Mountain Nature Reserve, with the aim of providing a scientific basis for the prevention and control of mosquito-borne diseases in the region. Methods Within Wuyi Mountain Nature Reserve 2022- 2023, 16 sampling sites were selected, where larvae were collected using the pipette method and adult mosquitoes were collected using the mosquito trap lamp method. Mosquito species identification was accomplished by integrating morphological characteristics and molecular identification techniques based on CO Ⅰ and CO Ⅱ gene sequences. Software tools such as ClustalX, DnaSP v5.0, and Network v4.6.1.0 were utilized to analyze the genetic differentiation (Fst), gene flow (Nm) among populations of Aedes japonicus, Aedes albopictus and Armigeres subalbatus. Results The mosquito specimens collected from the Wuyi Mountain Nature Reserve were identified as 30 species belonging to 8 genera within the Culicidae family. Among them, there were 10 species of Aedes, 13 species of Culex, 1 species each of Armigeres, Orthopodomyia, Uranotaenia, Tripyeroides, and Anopheles, and 2 species of Toxorhynchites. Analysis of the genetic structure of important mosquito populations showed that the haplotype diversity index (Hd) of Ae. japonicus was 0.994 7, with a generally moderate degree of differentiation between populations and a higher degree of genetic differentiation between populations 6 and 12; Aedeslbopictus had a haplotype diversity index of 0.634 0, with significant genetic differentiation between populations 1 and 2 compared to other groups; Armigeres subalbatus had a haplotype diversity index of 0.703 3, with substantial genetic differentiation and limited gene flow between population 2 and populations 3, 4, 6, and 7. Conclusions The mosquito species are rich in Wuyi Mountain Nature Reserve. A comprehensive survey of the composition and distribution of mosquito populations was carried out, and the characteristics of the population genetic structure of the important species of Ae. japonicus, Ae. Albopictus, and Ar. subalbatus populations were analyzed, providing valuable scientific data reference for local mosquito-borne ecological research and disease prevention and control.
