The Datong Lake is the largest freshwater aquaculture lake in Hunan Province. The macrofauna community and the environmental quality status were investigated in the Datong Lake in June 2019. Species composition, diversity and community structure of macrofauna were analyzed. The water quality was assessed by Shannon-Wiener diversity index (H'), biological index (BI) and Goodnight-Whitley index (IGW). A total of 32 species, belonging to 5 classes, 3 phyla were recorded. The dominant species were Bellamya aeruginosa, Paratanytarsus grimmii, Limnodrilus helveticus, Limnodrilus claparedianus, Limnodrilus hoffmeisteri, and Aulodrilus prothecatus. The values of Shannon-Wiener diversity, species evenness index and richness index were 1.51-3.62, 0.58-0.94 and 0.63-2.30, respectively. Compared with the historical data investigated in 1997 and 2008-2009, the species number, abundance and biomass of mollusks decreased, and the dominant group of mollusks showed a trend of succession from Bivalvia to Gastropoda. Assessment results by BI and IGW showed that most sites were in medium-heavy pollution status, and some sites were in light pollution status, while results of Shannon-Wiener index showed that most sites were in light pollution status.

Objective: To investigate the relationship between red blood cell distribution width (RDW), Neutrophils to lymphocytes ratio (NLR) and clinicopathological characteristics and prognosis of advanced non-small cell lung cancer (NSCLC) patients. From May 2017 to May 2019, 106 patients with advanced NSCLC (NSCLC group) in our hospital and 102 patients who were normal in physical examination (control group) were selected as the research object. Detection of RDW and NLR was performed, the relationship between RDW, NLR and clinicopathological characteristics and prognosis of NSCLC patients were analyzed. RDW, NLR in the NSCLC group were higher than those in the control group (P<0.05), RDW in age ≥ 60 years and lymph node metastasis with NSCLC patients were higher than those of age < 60 years and no lymph node metastasis with NSCLC patients (P<0.05), NLR in TNM staging Ⅳ stage, lymph node metastasis with NSCLC patients were higher than those in TNM staging Ⅲ stage, no lymph node metastasis with patients (P<0.05). Kaplan-Meier survival curve analysis showed that the surose in the low RDW group and the low NLR group (P<0.05). Univariate COX regression analysis showed that the differentiation degree, TNM stage, lymphatic metastasis, RDW and NLR were correlated with the prognosis of NSCLC patients (P<0.05), while multivariate COX regression analysis showed that lymphatic metastasis, RDW and NLR were correlated with the prognosis of NSCLC patients (P<0.05). RDW and NLR of advanced NSCLC patients are higher, RDW is related to age and lymph node metastasis, NLR is related to TNM stage and lymph node metastasis. High levels of RDW and NLR predict poor prognosis of NSCLC, which can be used as auxiliary indicators for prognosis assessment. [ABSTRACT FROM AUTHOR]

As the most important procedures during sugarcane harvesting, leaves cleaning and tails severing are influenced by different growth height and lodging status, and the operating speeds of the rollers not only affect the operating efficiency of the sugarcane harvester, but also influence the quality of harvesting. In order to investigate the effect laws on the quality of peeling leaves and breaking tails of leaf-crushing impeller, leaf-cleaning impeller and tail wheel, the leaf-crushing and tail-breaking system was designed and manufactured for sugarcane harvester test bench after sugarcane harvesting. In the system, elastic wire springs were arranged uniformly on the leaf-crushing impellers, the outer edge of the leaf-cleaning impeller were installed with rubber plates, and the severing tail components on the tail wheels were elastic rib. As the test bench works, the rolling leaf-crushing impeller, leaf-cleaning impeller and tail wheel lacerated and peeled leaves attached tightly on the canes by producing centrifugal and frictional force. According to the mechanical properties that anti-deformation and impact resistance of the tails were significantly lower than other parts, the anti-float mechanism was designed for breaking tails, the groove of the circular arc can prevent the lateral movement and ensure the smooth transportation of the sugarcane. The experiments of peeling leaves and breaking tails of sugarcanes were conducted in Zhejiang University, 2015. A quadratic general rotary unitized design was carried out with leaf-crushing impeller speed, leaf-cleaning speed and tail wheel speed as experimental factors, and with non-cleaning rate, tail broken rate, skin broken rate and non-break rate as experiment indices. By using SAS 9.3 regression analysis method, response surface method and combined with nonlinear optimization calculation method, the working parameters were calculated optimally, and the optimal factor combination was established. The results indicated that, the tail-broken rate and skin broken rate were influenced by the speeds of the three impellers significantly, however, the non-break rate was influenced by the speed of tail wheel only, but it had no effect on the non-cleaning rate. The contribution rate order of non-cleaning rate was leaf-crushing impeller speed, leaf-cleaning speed and tail wheel speed. The contribution rate order of tail broken rate was tail wheel speed, leaf-crushing impeller speed and leaf-cleaning speed. The contribution rate order of skin broken rate was tail wheel speed, leaf-cleaning speed and leaf-crushing impeller speed. The contribution rate order of non-break rate was tail wheel speed, leaf-cleaning speed and leaf-crushing impeller speed. The optimum parameter combination of the test bench after optimization was 512.9 r/min of leaf-crushing impeller speed, 418.8 r/min of leaf-cleaning speed and 307.0 r/min of tail wheel speed. At this level, non-cleaning rate achieved theoretical optimum value of 4.98%, tail broken rate was 88.39%, skin broken rate was 5.19% and non-break rate was 96.21%.Verification experiment showed that the experimental value of non-cleaning rate was 4.86%, tail broken rate was 90%, skin broken rate was 4.78% and non-break rate was 97.5%, which indicated that the experimental values were consistent with predicted results, and regression models established by the experiment were appropriate, which can provide references to design whole-stalk sugarcane harvester and improve the harvesting quality.
