The release of nitrogen and phosphorus from the decomposition of Nernopilerna nomurai was examined in a series of experiments under different incubation conditions such as different pH values, salinity values, temperatures and nitrogen and phosphorus concentrations. The results showed that the complete decomposition of Nemopilema nomurai generally took about 4-8 d. The release of nitrogen and phosphorus from the decomposition of Nemopilema nomurai could be divided into two stages： the early stage and the later stage, although the efflux rate of nitrogen was one order more than phosphorus. In the early stage of the decomposition of Nemopilema nomurai, the concentrations of dissolved nitrogen, dissolved phosphorus, total nitrogen and total phosphorus in seawater increased rapidly, and the concentration of nitrogen could reach the highest level in the whole degradation process. In the later stage of the decomposition, the concentrations of dissolved nitrogen and total nitrogen declined slowly, while the concentration of phosphorus in water could reach a maximum in the degradation process. High pH, low salinity, high temperature and N/P will promote the release of nitrogen; low pH is unfavorable to the release of nitrogen but favorable to the release of phosphorus. In addition, we found the concentrations of ammonium and phosphate in the bottom water were higher than those in the surface water during the period of jellyfish bloom in the ]iaozhou Bay, proving that nutrients released by the decomposition of jellyfish have significant influence on nitrogen and phosphorus in the field. For the whole Yellow Sea, nutrients released by jellyfish carcasses may reach up to （2.63±2.98）x10^7 mol/d of dissolved nitrogen （DN） and （0.74±0.84）x10^8 mol/d of dissolved phosphorus （DP） during the period of jellyfish bloom. The values are comparable to riverine inputs in a day, but much higher than sediment-water exchange flux in the Yellow Sea. The great amounts of nutrients must have significant influence on the nutrients balance of the Yellow Sea during the period of jellyfish dead and decomposition. Both the experimental data and field observations proved that the decomposition of jellyfish may release a great amount of nutrient to the surrounding environment during the period of jellyfish decomposition.展开更多

The scholars abroad have reconstructed uplift history of the plateau by studying geological process of the inner globe, they considered that the altitude of the plateau got up to the maximum at 14Ma (M.Coleman et al, 1995; S.Turner et al, 1993)or the plateau got to the present elevation at about 8Ma (T.M.Harrison,1992). The Chinese geologists make use of substitutes of outer environmental elements to deduce that the uplift of Qinghai—Tibet plateau began from 3 4Ma(Li Jijun,1995). It is obvious that there are the different views and controversies about the plateau uplift history.展开更多

Despite a ...The India-Asia collision and uplift of the Tibetan plateau are the most important geological events in Earth＇s history; it profoundly affects our understanding of global climate change during the Cenozoic. Despite a research history over half a century, the uplifting history remains hotly controversial. The early uplifting model suggested that the Lhasa terrane attained an elevation of 3-4 km at -99 Ma due to the Lhasa-Qiangtang collision. However, the evidences are mainly from deformation of the Lhasa terrane and inconsistency with the palaeontological data.展开更多

The existing evidence conflict measure methods are analyzed, and a new evidence conflict measure method called evidence similarity measure based on the Tanimoto measure is proposed, while a new evidence combination method is proposed on the basis of evidence similarity measure. Firstly, the conflict degrees between evidences are obtained through the evidence similarity measure. Then the evidence sources are modified based on the credibility of different evidences and the weights of conflicted parts of evidences on different focal elements are determined. Finally, the fusion result is obtained by this method. Numerical examples show that the proposed method can effectively fuse evidences when evidences are consistent or highly conflicted, and it has a fast convergence speed, a high degree of accuracy and good adaptability.展开更多

When the behaviors of illegally collecting evidences occur,does this mean that the followed-up series of collecting evidences behaviors are illegal?This is the issue with the exclusion of repeated verbal evidences. The exclusion of repeated verbal evidences is the inevitable requirement of the effective enforcement of the exclusionary rules of illegal evidences. Also,the exclusion of illegal evidences is the key and premise program of excluding repeated verbal evidences,but in Chinese judicial practice,the negative attitude of a kind of malfeasance of the court to enforce the exclusionary rules of illegal evidences,the 'homogeneous'kind of relationship between our court system,police system and procuratorial system in current period all mean that the exclusion of repeated verbal evidence will surely face ring upon ring obstacles. Otherwise,the restriction of judicial discretion in judicial practice requires the exclusion of repeated verbal evidences to insist on the principle of absolute exclusion,and this determines that the method of depending on judicial discretion to solve the problem of the scope of exclusion is inapplicable.展开更多

When the behaviors of illegally collecting evidences occur,does this mean that the followed-up series of collecting evidences behaviors are illegal?This is the issue with the exclusion of repeated verbal evidences. The exclusion of repeated verbal evidences is the inevitable requirement of the effective enforcement of the exclusionary rules of illegal evidences. Also,the exclusion of illegal evidences is the key and premise program of excluding repeated verbal evidences,but in Chinese judicial practice,the negative attitude of a kind of malfeasance of the court to enforce the exclusionary rules of illegal evidences,the 'homogeneous'kind of relationship between our court system,police system and procuratorial system in current period all mean that the exclusion of repeated verbal evidence will surely face ring upon ring obstacles. Otherwise,the restriction of judicial discretion in judicial practice requires the exclusion of repeated verbal evidences to insist on the principle of absolute exclusion,and this determines that the method of depending on judicial discretion to solve the problem of the scope of exclusion is inapplicable.
文摘Background:Cyclin-dependent kinase 4/6(CDK4/6)inhibitors have transformed the management of hormone receptor–positive/HER2–negative(HR+/HER2–)advanced breast cancer,yet evidence for elderly or poor-performance patients remains limited.This study examined real-world outcomes of palbociclib plus endocrine therapy in Asian patients,with additional subgroup analyses by age and performance status.Methods:We retrospectively analyzed 46 consecutive Asian patients with recurrent or de novo HR+/HER2−breast cancer treated with first-line palbociclib plus ET between April 2021 and March 2025.The primary endpoint was progression-free survival(PFS).Secondary endpoints included overall response rate(ORR),disease control rate(DCR),and safety.Subgroup analyses were performed by age(<70 vs.≥70 years)and performance status(PS;0–1 vs.2–3).Results:The median PFS was 26.6 months(range,1.4–69.5).Stratified by age,median PFS was 26.9 months in patients<70 years and 26.2 months in those≥70 years(p=0.760).By PS,PFS was 26.9 months for PS 0–1 and 17.8 months for PS 2–3(p=0.099).ORR was 60.9%and DCR 93.5%;notably,all PS 2–3 patients achieved disease control.Hematologic toxicities were common,with neutropenia(80.4%)and leukopenia(86.7%)predominating,but grade≥3 anemia was rare(2.2%).Elderly patients experienced anemia more frequently,while overall toxicity remained manageable.Dose reductions occurred in 47.8%without loss of efficacy.Conclusions:In routine Japanese practice,palbociclib plus ET provided prolonged PFS and high disease control consistent with pivotal trials and international real-world evidence.Importantly,elderly patients tolerated treatment well,and selected PS 2–3 patients also derived clinical benefit.These findings indicate that neither age nor PS alone should preclude the use of palbociclib in carefully monitored real-world patients.
