Laboratory animal science is an emerging interdisciplinary field supporting life science and medical research, and a key component of talent cultivation and technological innovation in medical colleges. Currently, this field faces challenges such as a significant imbalance between talent supply and demand and a weak systematic training system. To respond to national strategies and societal needs, Shandong First Medical University established the School of Laboratory Animal through industry-education integration during the 14th Five-Year Plan period. The school is based on The Medical Laboratory Technology major, cultivates application-oriented, interdisciplinary professionals in laboratory animal science, and has constructed a three-in-one training system integrating "course learning–scientific research–industry practice". Specific measures for talent cultivation include: optimizing the general education, professional courses, and intensive practical modules in the talent training program, and establishing the "Yellow River Class" integrating industry and education; implementing an undergraduate mentor system, and conducting scientific research training based on The Model Animal Research and Development Engineering Laboratory; collaborating with bases across the entire industrial chain of laboratory animal production, research, application, and quality control, appointing industry mentors, and strengthening practical teaching. Practice has shown that this system has been remarkably effective: a total of 320 undergraduate students have been enrolled since 2020; the employment rate of undergraduate graduates for two consecutive cohorts has reached 100%, and the postgraduate enrollment rate has exceeded 50%; undergraduate students have won numerous national and provincial awards in academic competitions, and have obtained multiple patents and published papers. In the future, the school will further integrate the advantages of medicine, agriculture, and science, optimize the depth and breadth of courses, strengthen the construction of faculty and teaching materials, and improve the undergraduate-master's integrated training mechanism. This article can provide a reference for the training of professionals in laboratory animal science and related biomedical fields in medical colleges.

Gut microbiota is the microbial community that is specifically planted in the human gut and interacts with the human body.It plays an important role in the human body by regulating the basal metabolism and immunity of the host to maintain the homeostasis of the human body.Once the intestinal flora is dysregulated,it can lead to multi-system diseases.Hashimoto's thyroiditis is an organ-specific autoimmune disease.The pathogenesis of Hashimoto's thyroiditis is complex and its incidence is increasing year by year,which is gradually becoming a serious public health disease affecting the world.In recent years,the relationship between gut microbiota and bridge onychitis has received extensive attention.A large number of studies have shown that the richness and diversity of intestinal flora in Hashimoto's thyroiditis patients are changed compared with healthy people.Studies have shown that traditional Chinese medicine therapy can play a role in treating this disease by regulating intestinal flora.This article systematically summarizes the relationship between the two and the effect of traditional Chinese medicine on the treatment of bridge onychitis by regulating intestinal flora,so as to provide some reference for research in this field.

BACKGROUND:Currently,different methods of model establishment have been derived from different injury modes of spinal cord injury.Traditional physical injury modeling methods have their own advantages and disadvantages,and there is a lack of more effective and stable animal models of spinal cord injury. OBJECTIVE:To establish a reproducible,controllable,trauma-free,low-mortality,more stable,widely applicable,and short-term postoperative care rat model of spinal cord injury. METHODS:Forty Sprague-Dawley rats with similar body mass and ages were randomly divided into a control group and an improved group,with 20 rats in each group.Animal models of spinal cord injury in the control group were constructed using a clip model method,while the improved group used a modified ligation method based on the compression method to make the spinal cord injury models using suture ligation based on fenestration.Postoperative comparisons were made between the two groups,assessing urination behavior,hematuria,pyuria(infection rate),mortality,scoliosis rate and Basso-Beattie-Bresnahan locomotor rating scale scores at 1,3,5,and 7 days after modeling. RESULTS AND CONCLUSION:Compared with the conventional modeling method,the modified ligation method based on the compression method resulted in faster recovery of urination behavior,lower hematuria rate,lower infection rate,lower mortality rate,lower scoliosis rate,and more concentrated and stable Basso-Beattie-Bresnahan scores(all below 2 points within 1 week).This proves that the modified ligation method based on compression is more suitable for the establishment of spinal cord injury models in rats.

OBJECTIVE To compare the anti-hepatitis mechanisms of Abrus pulchellus subsp. cantoniensis （Hance） Verdc. （AC） and Abrus pulchellus subsp. mollis（Hance） Verdc. （AM）. METHODS SD rats were randomly divided into blank group， AC- treated group， and AM-treated group， with each group consisting of 10 rats. The rats’ orbital venous blood was collected at 5， 15， 30 minutes， and 1， 1.5， 2， 4， 6， 8， 12 hours after gavage administration of 24 g/kg of the corresponding drug （calculated by crude drug） or water， respectively. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry technology was utilized to identify the prototype components present in the serum. The network pharmacology method was adopted to predict the anti-hepatitis active components， key targets， and signaling pathways of AC and AM. Additionally， molecular docking technology was utilized to verify the binding activity of the core active components with key targets. RESULTS A total of 35 prototype components migrating to the blood of AC and AM were identified in the serum of administered rats， among which 24 were common components. The active components in AC， such as acetylanguidine， physcion， soyasaponin A3 and soyasaponin Ⅰ， as well as those in AM， including vicenin 3， acetylanguidine，soyasaponin Ⅰ and schaftoside， all acted on key targets such as steroid receptor coactivator， phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit alpha， epidermal growth factor receptor （EGFR）， and protein kinase B1（Akt1）. These components modulated pathways in cancer， EGFR tyrosine kinase inhibitor resistance， and the phosphoinositide 3-kinase （PI3K） -Akt pathway， thereby exerting anti-hepatitis effects. Furthermore， the binding energies between these active components and their key targets were all less than －5 kJ/mol. CONCLUSIONS There are differences in the active components of AC and AM against hepatitis， but their mechanisms of action are similar. Both may exert their anti-hepatitis effects through pathways in cancer， EGFR tyrosine kinase inhibitor resistance， and the PI3K-Akt pathway.

OBJECTIVES: To investigate the role of the calcium/calmodulin (CaM)-mediated activation of calcineurin (CN)-nuclear factor of activated T cells (NFAT) signaling pathway in mediating the regulatory effect of hyperforin (HY) on stress-induced depression-like disorder (DP) in mice. METHODS: C57BL/6J mice were randomly divided into control group, DP model group, and hyperforin treatment group (n=15). Behavioral changes of the mice were assessed using open field test (OFT), sucrose preference test (SPT), tail suspension test (TST), light/dark box test (LDB), and novel object suppression test (NSFT). Immunohistochemistry was used to detect tyrosine hydroxylase (TH) expression in the CA1 region of the hippocampus, and serum serotonin (5-HT) and norepinephrine (NA) levels were detected with ELISA. Western blotting was used to analyze the expressions of TNF-α, IL-1β, IL-2, and CN-NFAT pathway proteins. In cultured BV-2 microglial cells with lipopolysaccharide (LPS) stimulation, the effects of hyperforin and CN inhibitor (CNIS) on expressions of ionized calcium-binding adapter molecule 1 (IBA-1), 5-HT, NA, inflammatory cytokines and CN-NFAT pathway proteins were examined using immunofluorescence assay, ELISA or Western blotting. RESULTS: Compared with the control mice, the mice in DP group showed significantly reduced activity in OFT, decreased sucrose consumption in SPT, reduced shuttle crossing in LDB, and lowered food intake in NSFT with significantly increased immobility in TST. The mice with DP showed significantly decreased TH-positive neurons, lowered 5-HT and NA levels, and increased expressions of TNF-α, IL-1β, IL-2 and CaM-CN-NFAT pathway proteins. In cultured BV-2 cells, LPS stimulation strongly increased cellular IBA-1 expression, decreased the levels of neurotransmitters (5-HT and NA), and increased the levels of inflammatory cytokines and CN-NFAT signaling, and these changes were effectively reversed by treatment with hyperforin or CNIS. CONCLUSIONS Hyperforin improves stress-induced depression-like behaviors in mice and activated BV-2 cells by targeting the CN-NFAT signaling pathway.

Objective To investigate the effect and mechanism of Congrong Shujing Granules on promoting microglial polarization and inhibiting neuroinflammation through the nucleotide-binding oligomeric domain-like receptor protein 3(NLRP3)/Caspase-1 signaling pathway.Methods Twenty Sprague-Dawley rats were assigned to the blank serum and Congrong Shujing Granules containing serum groups using random number table method,with 10 rats in each group.Rats in the Congrong Shujing Granules containing serum group received intragastric administration of Congrong Shujing Granules(2.57 g/kg)and the rats in the blank serum group received intragastric administration of physiological saline of equal volume.Blank serum and Congrong Shujing Granules containing serum were prepared separately.Mouse microglia cells BV-2 were cultured in vitro,and the optimal concentration of 1-methyl-4-phenylpyridine(MPP+)and optimal volume fraction of Congrong Shujing Granules containing serum were selected by the CCK-8 assay and immunofluorescence staining.And the NLRP3 inhibitor MCC950 was used as a postive control.Cells were divided into the blank serum group(10%blank serum),model group(10%blank serum+500 μmol/L MPP+),Congrong Shujing Granules containing serum group(10%Congrong Shujing Granules containing serum+500 μmol/L MPP+),and MCC950 group(10%blank serum+10 μmol/L MCC950+500 μmol/L MPP+),and intervened separately.After 14 h of intervention,morphological changes in BV-2 cells were observed.The contents of interleukin(IL)-1β,tumor necrosis factor-α(TNF-α),IL-6,and IL-4 were detected by an enzyme-linked immunosorbent assay.The mRNA expressions of differentiation cluster 86(CD86),inducible nitric oxide synthase(iNOS),CD206,and arginase 1(Arg1)were detected by real-time fluorescence PCR.The expressions of CD86,Arg1,Ionized calcium binding adaptor molecule 1(Iba1),and NLRP3 were detected by immunofluorescence staining.The expression of iNOS,Arg1,TNF-α,IL-6,IL-4,NLRP3,pro-cysteinyl aspartate specific proteinase 1(pro-Caspase-1),and Caspase-1 proteins was detected by Western blotting.Results Iba1 activation and expression increased under the MPP+(12 h,500 μmol/L)intervention(P<0.05),and cell viability was not affected.There was no statistically significant effect on cell viability after treatment with 10%Congrong Shujing Granules containing serum alone or in combination with MPP+(P>0.05).Compared to the blank serum group,BV-2 cells in the model group showed multiple branches and protruded in the shape of an amoeba.The contents of IL-1β,TNF-α,and IL-6 increased,while the contents of IL-4 decreased.The mRNA expressions of CD86 and iNOS increased,while mRNA expressions of CD206 and Arg1 decreased.The mean fluorescence intensity of CD86,Iba1,and NLRP3 increased,while the mean fluorescence intensity of Arg1 decreased.The protein expressions of iNOS,TNF-α,IL-6,NLRP3,pro-Caspase-1,and Caspase-1 increased,while the protein expressions of Arg1,IL-4 decreased,P<0.05.Compared to the model group,the Congrong Shujing Granules containing serum group and MCC950 group showed a decrease in the branch of cell protrusions,reduced cell activation,decreased levels of IL-1β,TNF-α,and IL-6,increased levels of IL-4,decreased expression of CD86 and iNOS mRNA,increased expression of CD206 mRNA,the decreased mean fluorescence intensity of CD86,Iba1,and NLRP3,the increased mean fluorescence intensity of Arg1,decreased expression of iNOS,TNF-α,IL-6,NLRP3,pro-Caspase-1,and Caspase-1 proteins,and increased expression of Arg1 and IL-4 proteins,P<0.05.Conclusion Congrong Shujing Granules containing serum may alleviate the MPP+-induced neuroinflammatory response by inhibiting the NLRP3/Caspase-1 signaling pathway to regulate M1/M2 phenotype polarization of microglia.

Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.
