In control group, cows were fed with basic feed, while in Chinese medicine Ⅰ group, cows were fed with basic feed containing 4% compound Chinese herb additive and in Chinese medicine Ⅱ group, cows were fed with basic feed containing 3% compound Chinese herb additive.All cows in the 3 groups were analyzed comparatively.[Result] Adding some compound Chinese herb additive into basic feed would increase milk yield and anti-heat stress ability of Holstein cow,besides,it also could decrease cow diseases such as cow mastitis.Chinese medicine Ⅰ would generate the highest economic benefit of practical production.[Conclusion] Adding Chinese herb additive into basic feed is an effective way for reliefing heat stress and increasing milk yield.展开更多

文摘To promote the growth of cutting seeding of poplar(Populus L.),nitrogen(N)fertilizer and surface weed managements were required.We here conducted a pot experiment to examine the effects of natural vegetation,barnyardgrass(Echinochloa Beauv.),and sesbania(Sesbania cannabina pers.)on the growth of poplar cutting seedlings,soil properties,and ammonia(NH3)volatilization under three N inputs(0,0.5,and 1.5 g/pot,i.e.,N0,N0.5,and N1,respectively).Results showed that N application promoted the growth of poplar cutting seedlings,including plant height,ground diameter,and biomass,compared with N0 treatment.Moreover,under N0,sesbania significantly increased the plant height by 87.1%,barnyardgrass and sesbania significantly increased the ground diameter(16.2%and 51.5%),and biomass(67.4%and 74.7%)of poplar cutting seedlings,compared with natural vegetation management.Compared to natural vegetation,soil organic matter(SOM)of barnyardgrass and sesbania covered soil significantly increased by 12.4%and 18.7%at N1,respectively.In addition,soil total N(TN)content was significantly increased by 15.8%in barnyardgrass planted at N0.The soil ammonium N(NH_(4)^(+)-N)content decreased with the planting of barnyardgrass and sesbania across all levels of N application.At N0.5,the nitrate N(NO_(3)^(−)-N)content of soil planted with barnyardgrass significantly increased compared to both the natural vegetation and the sesbania groups.Compared to the natural vegetation,the soil available phosphorus(AP)content of the barnyardgrass group significantly increasing by 78.8%at N0.5,soil available potassium(AK)content was significantly reduced by 12.5%in the sesbania group at N0 and increased by 24.1%in the barnyardgrass group at N1.We found that cumulative NH3 emissions were significantly higher in all treatment groups at the N1 level than that at the N0.5 level,while the differences among the three plants treated were not significant.The results suggest that both barnyardgrass and sesbania promote seedling growth in the short term,while also increase certain properties.Therefore,effective herb management during the seedling stage is recommended in nurseries to support seedling growth and retain soil fertility.

文摘Sjögren’s syndrome(SS)is an autoimmune disease characterized primarily by oral and periocular dryness.Astragalus-Salvia(AS)and Ophiopogon-Dendrobium(OD)represent two frequently utilized herb pairs in SS treatment.While the combination of AS-OD herb pairs demonstrates clinical efficacy in alleviating SS symptoms,its underlying mechanism remains unclear.This investigation sought to assess the therapeutic effects and elucidate the potential mechanisms of AS-OD in non-obese diabetic(NOD)/Ltj mice with SS.The study utilized NOD/Ltj mice as SS models,administering AS-OD treatment for 10 weeks at doses of 113.1,226.2,and 339.3 mg·d−1·20 g−1.Results demonstrated that AS-OD improved SS symptoms,evidenced by enhanced salivary flow rate,decreased anti-SSA/Ro and anti-SSB/La antibody levels,increased swimming duration,and reduced lactate(LA)and blood urea nitrogen(BUN)levels in NOD/Ltj mice.AS-OD reduced lymphocyte infiltration,enhanced Aquaporin-5(AQP5)expression in the submandibular gland,decreased inflammatory cytokine levels in the submandibular gland,and reduced the T helper type 17/regulatory T lymphocyte(Th17/Treg)cell ratio in the spleen.Transcriptomic and proteomic analyses indicated AS-OD’s involvement in regulating phosphatidylinositol-3-kinase/protein kinase B(PI3K/AKT)and Janus kinase 3/signal transducer and activator of transcription 3(JAK1/STAT3)pathways,with inhibitory effects validated in both NOD/Ltj mice submandibular gland and A-253 cells.Furthermore,AS-OD enhanced cell viability and reduced A-253 cell apoptosis through the PI3K/AKT pathway.In A-253 cells,AS-OD reduced inflammatory cytokine levels,CXC chemokine ligand 9/10(CXCL9/10),and T-cell chemotaxis by inhibiting the JAK1/STAT3 pathway.AS-OD mitigates SS by suppressing inflammation and immune responses through the PI3K/AKT and JAK1/STAT3 pathways.
