Objective To investigate the possible protective effect of adenoviral vector expressing interleukin-1β (IL-1β) small hairpin RNA (shRNA) on spinal cord injury (SCI) and its mechanism in rats.Methods Forty-eight adult male Sprague-Dawley rats were randomly assigned to 4 groups including the Sham, the Vehicle,the Ad-GFP and the Ad-shIL-1β groups.SCI was induced by epidural compression.Motor function of hind limbs was evaluated by Basso-Beattie-Bresnahan (BBB) score, the expressions of green fluorescence in injured spinal cord tissue were observed by fluorescence microscope.Enzyme-linked immunosorbent assay (ELISA) and immunofluorescence were also performed.Results The expressions of green fluorescence in injured spinal cord tissue were observed in the Ad-GFP and Ad-shIL-1β groups one day after SCI.Significant functional improvement was observed in the Ad-shIL-1β group (8.17 ± 1.17, 10.17 ± 0.98 and 11.33 ± 0.82, respectively) compared to the Vehicle (4.00 ± 0.89, 5.67 ± 1.03 and 6.17 ± 1.17, respectively) and Ad-GFP (3.83 ± 0.98, 5.33 ± 1.21 and 5.67 ± 1.03, respectively) groups at 7, 14 and 21 days after SCI (P ＜ 0.05).Rats in the Ad-shIL-1β group had less neuronal loss 21 days after SCI.In addition, IL-1β downregulation significantly decreased IL-1β, tumor necrosis factor-or (TNF-α) and IL-6 levels (138.83 ± 7.96,143.38 ± 10.20 and 120.43 ± 9.79 in Ad-shIL-1β group;169.33 ± 11.45, 172.33 ± 8.26 and 163.00 ± 9.57 in Vehicle group;172.83 ± 10.85,167.48 ± 8.19 and 159.48 ± 10.98 in Ad-GFP group, respectively) one day after SCI (P ＜ 0.05).Conclusion This study demonstrated that the IL-1β downregulation may have potential therapeutic benefits for improving the outcomes after SCI.

Objective To more intuitively understand the quality control for laboratory animals and further achie-ving a more scientific and reasonable management of laboratory animals, the infection index as evaluation criteria was intro-duced. Then the best way to calculate infection index was explored in order to more scientifically reflect the infection status of laboratory animals. Methods Infection index, also called the degree of infection, is a qualitative indicator of monito-ring laboratory animal quality. After arranging, analyzing, processing and gathering the data from laboratory animal quality monitoring, the index reflects synthetically the pathogen infection status or trend of a particularly investigated experimental animal population or the development of certain experimental animals. Results In general, the pathogen infection index of mice was slightly decreased, while the pathogen infection index of rats roughly increased year by year. In comparing infec-tion index by different pathogens, the parasite infection index of mice was found to be higher than bacteria and virus infec-tion indexes, while the bacteria infection index of rats was higher than parasite infection index and virus ones. Conclusions The infection index model intuitively reflects the quality control status of laboratory animals. The analysis also reveals that the parasite monitoring of the mice and the bacteria detection of rat needs to be reinforcement. In addition, the index of infection reveals that the pathogen infection of mice is well under control, while that of rats tends to be more serious year by year.

Objective To compare the differences of bacterial distribution of intestinal flora in Microtus fortis living under laboratory feeding and wild survival conditions. Methods The 16S rDNA-V4-V5 region of bacteria in the ileocecal contents from Microtus fortis raised in lab and captured in wild were measured by high-throughput sequencing. The number of operational taxonomic units(OTUs)were sorted and calculated,and the species abundance and distribution and difference were analyzed. Results The rarefaction curves indicated that adequate sampling was achieved. At the phylum level,the distribution of intestinal flora between two groups was similar. The experimental group had a unique phylum, Lentisphaerae. The wild type group had 3 unique phylums,Fusobacteria,Thaumarchaeota and an unclassified phylum. At the genus level, the kind of intestinal flora in the wild type group was more abundant than the experimental group. Ruminococcus is the largest differential genus. Conclusions The microbial community structure and differences of Microtus fortis living under different conditions are obtained. It may further enrich the basic biology data of Microtus fortis.

As the incidence of male infertility has been increasing during recent years, it is urgent to reveal the pathogenesis of male infertility, as well as to develop the new drugs for treatment of male infertility, in order to solve the declining birth rate and aging problems. The construction and application of male infertile animal models is critical for drug development, which plays an important role in accurately evaluating the efficacy and mechanism of infertility treatment. A suitable infertility model not only can reduce the repeated drug efficacy evaluations, reduce animal usage and the cost of new drug development, but also has important reference value for subsequent clinical trial research. Male infertility laboratory animal models can be constructed through chemical, physical, endocrine, environmental estrogen, gene modification, and immune methods. This article mainly introduces the existing male infertility animal models available for drug development, and briefly introduces the application progress of each model to provide reference for the male infertility drug researchers.

In recent years, with the rapid development of life sciences, the use of laboratory fish in toxicology, genetics, developmental biology and medicine has increased dramatically, and they have gradually become important new model organisms. At the same time, the welfare of laboratory fish has also received increasing attention. Although the research level of experimental fish welfare is still in a relatively early stage compared to terrestrial experimental animals, developed regions such as Europe and America have established corresponding legal frameworks to safeguard the welfare of laboratory fish in research. This article elucidates the current developmental status of laboratory fish welfare, discusses the rationale behind the imperative to prioritize and enhance their welfare, deeply investigates factors influencing their welfare from the feeding stage and experimental stage. Moreover, it explores strategies for augmenting welfare standards, with the overarching aim of propelling the continual improvement of laboratory fish welfare in our country.
