Objective:To estimate the burden of influenza-associated outpatient consultations in China from 2011 to 2021 surveillance years to provide a reference for developing influenza prevention, control strategies, and vaccination policies.Methods:Data on influenza-like illness (ILI) and virological confirmation of sentinel specimens from 2011 to 2021 surveillance years were extracted from China's national sentinel surveillance system. Generalized additive models were fitted to estimate influenza-associated excess ILI outpatient burden, accounting for seasonal baselines and meteorological factors.Results:Influenza was associated with an average of 1.66 (95% CI: 1.51-1.80) excess ILI consultations per 1 000 person-years (py) in China each year from 2011 to 2021 surveillance years. The influenza-associated outpatient burden was similar across different virus types/subtypes. Influenza A(H1N1)pdm09 led to a higher rate of influenza- associated ILI consultations [0.65 (95% CI: 0.53-0.76) per 1 000 py] compared to other types/subtypes. The age groups with the highest burdens were children aged 0-4 years and 5-14 years, with excess outpatient consultation rates of 15.23 (95% CI: 13.73-16.73) per 1 000 py and 13.53 (95% CI: 12.49-14.52) per 1 000 py, respectively. Conclusions:Influenza caused many outpatient consultations in China, particularly among children aged 0-14. Continuous influenza monitoring and disease burden assessment should be conducted, and close attention should be paid to the changing trends of various influenza virus types/subtypes. When formulating vaccination strategies, priority should be given to recommending vaccination for high-risk populations, such as children.

One of the important causes of developmental epileptic encephalopathy (DEE) is the mutation of ion channel genes, including the mutation of the CACNA1E gene. CACNA1E-related DEE cases were first reported in 2018.The mutation types include new missense mutations, nonsense mutations and frameshift mutations, but the correlation between mutation sites and types with the phenotype of DEE is not clear.This review aims to summarize the reported CACNA1E-related DEE cases, and explore the correlation between the clinical phenotype of CACNA1E-related DEE and gene mutation sites and mutation types.Meanwhile, possible pathogenesis of CACNA1E-related DEE and the progress of drug intervention were reviewed to provide references for the diagnosis and precise treatment of DEE.

OBJECTIVE To investigate the effects and mechanism of atractylodin on inflammatory injury of periodontal tissue and alveolar bone loss in periodontitis rats. METHODS A total of 144 SD rats were divided into control group (intragastric and intraperitoneal injection of normal saline), model group (intragastric and intraperitoneal injection of normal saline), atractylodin low-dose, medium-dose and high-dose groups (intraperitoneal injection of 6.665, 13.33, and 26.66 mg/kg atractylodin), metronidazole group (positive control group, intragastric injection of 0.05 g/kg metronidazole, intraperitoneal injection of normal saline), AMD3100 [stromal cell-derived factor-1 (SDF-1)/CXC chemokine receptor-4 (CXCR4) pathway inhibitor] group (intragastric injection of 1 mg/kg AMD3100, intraperitoneal injection of normal saline), atractylodin high-dose+AMD 3100 group (intraperitoneal injection of 26.66 mg/kg atractylodin, intragastric injection of 1 mg/kg AMD3100), with 18 rats in each group. Except for the control group, all other groups of rats were inoculated with Porphyromonas gingivalis to construct a periodontitis model. After successful modeling, they were given relevant medicine or normal saline, once a day, for 4 consecutive weeks. The gingival index of rats was detected; the levels of interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) in rat serum were also determined; alveolar bone resorption, periodontal histopathologic changes and the number of osteoclasts were detected by methylene blue staining, HE staining and TRAP staining, respectively. The expressions of osteoprotegerin (OPG), receptor activator of NF-κB ligand (RANKL), SDF-1 and CXCR4 proteins were determined. RESULTS Compared with the control group, serious pathological injury of periodontal tissue was found in the model group, the gingival index, the levels of IL-6 and TNF- α, alveolar bone absorption value, the number of osteoclasts, and the expression of RANKL protein were all increased significantly (P<0.05), while the expressions of OPG, SDF-1 and CXCR4 proteins were decreased significantly (P<0.05). Compared with the model group, pathological injury of periodontal tissue in rats was reduced; the gingival index, the levels of IL-6 and TNF-α, alveolar bone resorption value, osteoclast number and RANKL protein expression were decreased significantly, while protein expressions of OPG, SDF-1 and CXCR4 were increased significantly in atractylodin low-dose, medium-dose and high-dose groups and metronidazole group (P<0.05). The change trend of corresponding indexes in the AMD3100 group was opposite to the above (P<0.05). AMD3100 attenuated the inhibitory effect of high-dose atractylodin on inflammatory response and alveolar bone loss in rats with periodontitis (P<0.05). CONCLUSIONS Atractylodin may improve the inflammatory response and alveolar bone loss in periodontitis rats by activating the SDF-1/CXCR4 signaling pathway.
