Chinese Journal of Biologicals 2026;39(01):44-49
Objective To analyze the rotavirus(RV) vaccine coverage among children in the birth cohorts in Shijingshan District of Beijing from 2015 to 2023, so as to provide a scientific support for RV vaccination.Methods The data were collected through the Beijing Immunization Planning Information Management System, and descriptive epidemiological methods were used for statistical analysis.Results A total of 36 248 doses of RV vaccines were inoculated among children born in Shijingshan District of Beijing from 2015 to 2023, and the overall coverage levels for the first, second, and third doses were 43. 03%, 28. 55% and 18. 72%, respectively. The vaccination rate had shown an overall upward trend over the years(χ~2_(trend)= 4 554. 383, 8 016. 090 and 9 143. 411, respectively, each P < 0. 001). The coverage levels for the first, second, and third doses of Lanzhou lamprotavirus vaccine(LLR) were 22. 91%, 9. 04% and 1. 28% among the 2015-2023 birth cohorts respectively, and the vaccination rate had shown an upward trend followed by a downward trend with the years. The coverage levels for the first, second, and third doses of pentavalent human-bovine reassortant rotavirus vaccine(RV5) among the 2018-2023 birth cohorts were 33. 30%, 32. 30% and 28. 87%, respectively, and the vaccination rate had shown an overall upward trend over the years(χ~2_(trend)= 3 745. 642, 3 402. 195 and 3 237. 052, respectively, each P < 0. 001). The vaccination rates of the first, second, and third doses of LLR and RV5 in different regions showed statistically significant differences(LLR: χ~2=1 244. 175, 1 100. 036 and 44. 453, respectively, each P < 0. 001; RV5: χ~2= 649. 139, 567. 390 and 464. 887, respectively,each P < 0. 001), with a gradual increasing trend from west to east area.Conclusion The vaccination rate of RV vaccine among children born in Shijingshan District of Beijing from 2015 to 2023 is relatively low, and it is necessary to further strengthen publicity and enhance parental awareness, so as to increase the RV vaccination rate for the effective prevention of childhood RV diarrhea.

Hypercholesterolemia is a significant risk factor for the development of atherosclerosis. 2',3',5'-Tri-O-acetyl-N 6-(3-hydroxyphenyl) adenosine (IMM-H007), a novel AMPK agonist, has shown protective effects in metabolic diseases. However, its impact on cholesterol and triglyceride metabolism in hypercholesterolemia remains unclear. In this study, we aimed to elucidate the effects and specific mechanisms by which IMM-H007 regulates cholesterol and triglyceride metabolism. To achieve this goal, we used Apoe -/- and Ldlr -/- mice to establish a hypercholesterolemia/atherosclerosis model. Additionally, hepatocyte-specific Ampka1/2 knockout mice were subjected to a 5-week high-cholesterol diet to establish hypercholesterolemia, while atherosclerosis was induced via AAV-PCSK9 injection combined with a 16-week high-cholesterol diet. Our results demonstrated that IMM-H007 improved cholesterol and triglyceride metabolism in mice with hypercholesterolemia. Mechanistically, IMM-H007 modulated the AMPKα1/2-LDLR signaling pathway, increasing cholesterol uptake in the liver. Furthermore, IMM-H007 activated the AMPKα1-FXR pathway, promoting the conversion of hepatic cholesterol to bile acids. Additionally, IMM-H007 prevented hepatic steatosis by activating the AMPKα1/2-ATGL pathway. In conclusion, our study suggests that IMM-H007 is a promising therapeutic agent for improving hypercholesterolemia and atherosclerosis through the activation of AMPKα.

Objective:To observe the effect of mirror threshold load training on respiration of persons with respiratory muscle fatigue after a cerebral hemorrhage.Methods:Fifty cerebral hemorrhage patients with respiratory muscle fatigue were randomly divided into an observation group and a control group, each of 25. In addition to routine rehabilitation training, the control group was given threshold load training of the respiratory muscles, while the observation group was provided with mirror threshold load training, twice a day in the morning and afternoon, 5 days a week for 4 weeks. Before the experiment and after 1, 2, 3 and 4 weeks of the treatment, everyone′s maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) was recorded. Before and after the 4 weeks forced expiration volume in the first second (FEV1) was measured along with 25% of the forced expiration volume (FEF25), maximum sound time (MPT) and respiration rate (RR).Results:At each time point the MIP and MEP values of both groups were significantly better than those before the treatment. After 4 weeks the average MIP and MEP values of the observation group were significantly better than those of the control group. And after 4 weeks the FEV1, FEF25, MPT and RR values of both groups had also improved significantly, on average. All of the observation group′s averages except MPT were then significantly better than the control group′s averages.Conclusions:Mirror threshold load training of the respiratory muscles can significantly improve the respiration of persons with respiratory muscle fatigue after a cerebral hemorrhage. It is more effective than respiratory muscle threshold load training.
