Objective: To design and develop a biological rhythm monitor and data analysis system for studying biological rhythm in animals under different conditions.
Methods: The system was a distributed digital control system consisting of a computer and zeitgeber generators. Acquisition of data on animal activity and generation of zeitgeber were modularized to meet the multiple requirements of experiment. System functions and animal adaptability to this system were detected by monitoring the rhythm of mouse activities under different light-dark cycles.
Result: The animal experiment showed that the functions of this system, including data acquisition, data communication, light regulation and data analysis, were qualified for application. There was no apparent malfunction.
Conclusion: The system is safe, reliable and easy to operate. The system could be a very useful system to study biological rhythm in animals.

Body size declines are a common response to warming via both plasticity and evolution, but variable size responses have been observed for terrestrial ectotherms. We investigate how temperature-dependent development and growth rates in ectothermic organisms induce variation in size responses. Leveraging long-term data for six montane grasshopper species spanning 1,768-3 901 m, we detect size shifts since ~1960 that depend on elevation and species' seasonal timing.

Through mid-January, the risk of outpatient illness due to influenza A is reduced by about half among vaccinated vs unvaccinated individuals. Adjusted VE is 53% (95% CI: 36-65) against A(H1N1)pdm09, comprised of clades 5a.

Vaccination coverage for influenza among diabetic populations remains suboptimal. Various factors contribute to this low vaccination rate, with a prominent issue being skepticism among potential vaccine recipients regarding vaccine effectiveness. We conducted a retrospective test-negative case-control study among diabetic patients aged 60 years and older in Ningbo, Zhejiang Province, China, spanning for four influenza seasons from 2018-19 to 2021-22.

Background: Hypertensive Disorder during Pregnancy (HDP) is the most prevalent obstetric conditions in maternal health, but the etiology of most cases remains unexplained. Seasonal variations in the conception of HDP may offer insights into the potential seasonal-specific risk factors.
Methods: Data were sourced from the China's National Maternal Near Miss Surveillance System (NMNMSS) between January 1, 2012, and December 31, 2021.
