| 1 | Response of community composition and biomass of submerged macrophytes to variation in underwater light, wind and trophic status in a large eutrophic shallow lake显示文摘Light climate is of key importance for the growth, community composition of submerged macrophytes in lakes and, they, in turn, are affected by lake depth and the degree of eutrophication. To test the relationships between submerged macrophyte presence and the ratio of Secchi disk depth(SDD) to water depth, i.e. SDD/depth, nutrients and wind, we conducted an extensive sampling campaign in a macrophyte-dominated area of the eastern region( n = 36) in 2016 in Lake Taihu, China, and combined the data gathered with results from extensive physico-chemical monitoring data from the entire lake. We confirmed that SDD/Depth is the primary factor controlling the community composition of macrophytes and showed that plant abundance increased with increasing SDD/Depth ratio( p < 0.01), but that only SDD/Depth > 0.4 ensured growth of submerged macrophytes. Total phosphorus and total nitrogen also influenced the growth and community composition of macrophytes( p < 0.01), while Chl a was an indirectly affecting factor by reducing underwater light penetration. Wave height significantly influenced plant abundance( p < 0.01), whereas it had little effect on the biomass( p > 0.05). The key to restore the macrophyte beds in the lake is to reduce the nutrient loading. A decrease of the water level may contribute as well in the shallow bays but will not bring plants back in the main part of the lake. As the tolerance of shade and nutrients varied among the species studied, this should be taken into account in the restoration of lakes by addition of plants. | Baili Dong Yongqiang Zhou Erik Jeppesen Kun Shi Boqiang Qin | 2021 | Journal of Environmental Sciences2021，33，5： | 10 |

| 3 | The role of endotoxin in the pathogenesis of gastric mucosal damage in cirrhotic rats with portal hypertensive gastropathy显示文摘Objective:To study the role and the mechanism of endotoxin in the pathogenesis of gastric mucosa during portal vein hypertension gastrography(PHG) in the rats with cirrhosis.Methods: Rat model for PHG was established by injection of tetrachloride.The animals were injected with endotoxin i.p.at 3 mg/kg and endotoxin antagonist BPI21 i.v.at 2.0 mg/kg.The plasma level of endotoxin as well as the gastric mucosal level of tumor necrosis factor alpha(TNF-α) was measured with azobenzene and ELISA respectively.Furthermore,the pathological changes of the gastric mucosa were studied with HE stainning.Results:In rats with PHG,increased endotoxin and TNF-αas well as the gastric pathological lesion were observed.Injection of endotoxin remarkably increased plasma level of endotoxin as well as the gastric mucosal level of tumor necrosis TNF-αand induced more serious gastric lesion.Animals injected with endotoxin antagonist BPI21 showed improved gastric mucosal lesion,accompanied by the declining TNF-αlevel.Conclusions:Our results suggestes that endotoxin may play a pathogenetic role in PHG by inducing the expression of TNF-α. | Cheng Lan Xiaoning Sun Liwei Dong Baili Huang Su Yuan Keli Wu | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，3： | 0 |
