The phylogenetic analyses of the subfamily Limenitidinae are performed based on 1 471 bp of mtDNA cytochrome oxidase subunit I （COI） gene sequence data which were obtained from 21 individuals spanning 9 genera, along with those of 17 species obtained from GenBank, using Apatura iris, Aglais urticae, and Polyura dolon as outgroup species. Although the transitions at the third codon positions of the COI data set were highly saturated, they were still retained for analysis as they contain the majority of the phylogenetic information, and thus, the maximum pasimony （MP） under different weighting schemes and maximum likelihood （ML） trees were reconstructed in this study. The results showed that within this subfamily, the results based on the COI gene sequences are approximately identical to the traditional classification results. However, the clustering of Lexias pardalis and Tanaecia julii within the genus Euthalia as well as the clustering of Phaedyma aspasia within the genus Neptis with weak support are different from that of the current classification scheme made by Chinese scholars. The genus Limenitis is splited into two subclusters in the trees constructed by using MP and ML methods. These results support one of the strongest hypotheses for the tribe relationships within Limenitidinae.

BACKGROUND:Many studies have confirmed that serum total cholesterol(sTC) concentrations were associated with underlying liver damage and the synthesis capacity of ***, the role of postoperative sTC level on evaluating graft function and predicting survival of recipients who underwent liver transplantation has not been ***:Clinical data of 231 living donor liver transplantation recipients from May 2003 to January 2015 were retrospectively collected. Patients were stratified into the low sTC group(sTC <1.42 mmol/L, 57 recipients) and high sTC group(sTC ≥1.42 mmol/L, 174 recipients) according the sTC level on postoperative day 3 based on receiver-operating characteristic curve analysis. The clinical characteristics and postoperative short-and long-term outcomes were compared between the two ***:Recipients with sTC <1.42 mmol/L experienced more severe preoperative disease conditions, a higher incidence of postoperative early allograft dysfunction(38.6% vs 10.3%, P<0.001), 90-day mortality(28.1% vs 10.9%, P=0.002)and severe complications(29.8% vs 17.2%, P=0.041) compared to recipients with sTC ≥1.42 mmol/L. The multivariate analysis demonstrated that sT C <1.42 mmol/L had a 4.08-fold(95% CI:1.83-9.11, P=0.001) and 2.72-fold(95% CI:1.23-6.00,P=0.013) greater risk of developing allograft dysfunction and 90-day mortality, and patients with sTC <1.42 mmol/L had poorer overall recipient and graft survival rates at 1-, 3-, and 5-year than those with sTC ≥1.42 mmol/L(67%, 61% and 61% vs 83%, 71% and 69%, P=0.025; 65%, 59% and 59% vs 81%,68% and 66%, P=0.026, respectively). Cox multivariate anal-ysis showed that sTC <1.42 mmol/L was an independent predicting factor for total recipient survival(HR=2.043; 95% CI:1.173-3.560; P=0.012) and graft survival(HR=1.905; 95% CI:1.115-3.255; P=0.018).CONCLUSIONS:sTC <1.42 mmol/L on postoperative day 3 was an independent risk factor of postoperative early allograft dysfunction, 90-day mortality, recipient a

Symbiotic microbiomes of Sphagnum have been confirmed to play a fundamental role in carbon and nitrogen cycles, however, little is known about microbiomes associated with other bryophytes in subtropical peatland ecosystems. To explore the differences in community structure, metabolic potential and interaction relationship of bacterial microbiomes associated with different bryophytes species, the gametophytes of three bryophyte species(Sphagnum palustre, Aulacomnium androgynum, and Polytrichum commune) and their underlying peat sediments were collected from the subtropical Dajiuhu Peatland and subjected to Illumina high-throughout sequencing of 16S r RNA gene. Results showed that bacterial diversity was lowest in S. palustre, the dominant moss species, among the three moss species investigated in Dajiuhu Peatland. Bacterial communities from bryophytes clearly separated with those from sediments as indicated by both phylogenetic and taxonomical approaches. Linear discriminant analysis effect size(LEf Se) identified 30 and 36 indicator taxa in mosses and peat sediments. Bacteroidetes, Verrucomicrobia and Thermoleophilia significantly enriched in S. palustre, A. androgynum and P. commune, Chloroflexi, Proteobacteria and Acidobacteria subgroup 6 was indicator taxa for corresponding underlying sediments, respectively. Despite of these differences in compositions, bacterial functional structures were similar among all bryophytes, such as abundant aerobic heterotrophs, rare nitrifiers and denitrifiers. This phenomenon was also observed among the underlying sediments. Network analysis indicated that Proteobacteria and Acidobacteria located in the center of network and exerted strong interactions to other taxa. The sub-network of bacterial communities in sediments was more connected and microbial groups were more competitive than those in bryophytes subnetwork. Our results offer new insight into the community structure, ecological function and interaction pattern of bacterial

As an important component of cryospheric provisioning services, freshwater provisioning services of the cryosphere is particularly critical to human well-being and socio-economic sustainability. It is imperative to quantitatively estimate the value of freshwater provisioning services to facilitate informed decision-making for ecosystem management and economic development. This study assessed the economic value and associated changes in benefits of freshwater provisioning services for industrial, agricultural, services and domestic water uses combining cost-based method and hydrological model in the Urumqi River during 2010–2016. The results showed that the average annual economic value of agricultural, services, domestic and industrial water uses generated from freshwater provisioning services were estimated to be 1.7, 4.4, 9.9, and 15.7 million CNY. The annual value of snowmelt provisioning services of sectorial water uses was much higher than that of glacier meltwater due to the greater contribution of snowmelt to outlet streamflow than glacier melt. The relative contributions of agricultural, services, domestic and industrial sectors to total economic value of freshwater provisioning services were 6%, 13%, 32%, and 49% respectively, depending on the meltwater supply and market prices. The benefits of freshwater provisioning services from different sectors generally increased in 2010–2016, with a significant increase in the services sector. Considering the impact of changes in freshwater supply under climate change on the assessment of cryospheric provisioning services, the results emphasize the necessity of promoting industrial structure optimization and adopting resource-efficient policies.

Background The influence of homocysteine （Hcy） on the migration and proliferation of vascular smooth muscle cells has been well established. However, the impact of Hcy levels on the progression of non-culprit coronary lesions （NCCLs） is controversial. This study aims to evaluate whether the plasma level of Hcy is related to the progression of NCCLs after percutaneous coronary stent implantation in elderly patients with acute coronary syndrome （ACS）. Methods A total of 223 elderly patients （〉 65 years old） with ACS undergoing stent im- plantation and follow-up coronary angiography were enrolled. Laboratory determination comprised of blood sample evaluation for Hcy was carried out before baseline coronary intervention. The patients were classified into two groups according to the blood Hcy tertiles （〉 15 mmol/L or 〈 15 mmol/L）. Patients were followed up for 12.2 months. NCCL progression was assessed by three-dimensional quantitative coronary angiography. Results A significantly higher ratio of NCCL progression was observed in the group with baseline Hcy concentrations above 15 mmol/L compared to the group with concentrations below 15 mmol/L （41/127, 32.3% vs. 14/96, 14.6%, P = 0.002）. Multivariate Cox regression analysis showed that Hcy and diabetes mellitus were independent risk factors for NCCL progression. The crude haz- ard ratio （HR） of NCCL progression for Hcy level was 1.056 （95% CI： 1.01-1.104, P = 0.015）. The adjusted HR of NCCL progression for Hcy level was 1.024 （95% CI： 1.007-1.042, P = 0.007）. The adjusted HR of NCCL progression for diabetes mellitus was 1.992 （95% CI： 1.15-3.44, P = 0.013）. Conclusions Hcy is an independent risk factor for NCCL progression after 12 months of follow-up in elderly patients with ACS who has undergone percutaneous coronary stenting.

A microcalorimetric study on molecular recognition of p-sulfonatocalix[4]arene derivatives at selfassembled interface in comparison with in bulk water was performed,inspired by the dramatic change in physicochemical characteristics from bulk water to interface.A total of six cationic molecules were screened as model guests,including ammonium（NH_4~＋）,guanidinium（Gdm~＋）.N,N＇-dimethyl-1,4-diazabicyclo[2.2.2]octane（DMDABCO^（2＋））,tropylium（Tpm~＋）,N-methyl pyridinium（N-mPY＊） and methyl viologen（MV^（2＋））.The complexation with NH_4~＋.Gdm~＋ and DMDABCO2＊ is pronouncedly enhanced when the recognition process moved from bulk water to interface,whereas the complexation stabilities with Tpm~＋,N-mPY~＋ and MV2＊ increase slightly or even decrease to some extent.A more interesting phenomenon arises from the NH_4~＋/Gdm~＋ pair that the thermodynamic origin at interface differs definitely from each other although with similar association *** results were discussed in terms of differential driving forces,electrostatic,hydrogen bond as well as π-stacking interactions,originating from the unique physicochemical features of interfaces,mainly the polarity and dielectric constant.
