Objective The dynamic accumulation trend of secondary metabolite in cultivated Spatholobus suberectus Dunn at different growth time was studied to provide scientific basis for confirming its reasonable harvesting time. Methods Ethanol-soluble extractives were measured by the method recorded in Chinese Pharmacopoeia ( A) Appendix XA ( 2010 edition). The content of total flavonoids was tested by ultraviolet spectrophotometer. The contents of protocatechuic acid, catechin, and epicatechin in Spatholobus suberectus Dunn were determined by high performance liquid chromatography ( HPLC). Results The contents of ethanol-soluble extractives, total flavonoids and the major components such as protocatechui cacid, catechin and epicatechin in Spatholobus suberectus Dunn showed increasing trend with the prolongation of growth time. The changes of contents of alcohol-soluble extract, total flavonoids and epicatechin in samples collecting at different months in one year showed a parabolic trend, and the contents reached the peak values from July to September. Catechin content kept increasing continually. The content of ethanol -soluble extractives of Spatholobus suberectus Dunn aged 4-6 years met the requirements of the current edition of Chinese Pharmacopoeia when harvested from July to September. Conclusion It is preliminarily recommended that Spatholobus suberectus Dunn cultivated for more than 7 years is suitable for harvesting, but the optimal harvest period and the harvest month still need to be further studied.

Objective To explore the seed protein extraction method for Amomum villosum Lour., so as to lay the foundation for the study of differential proteomics of Amomum villosum Lour. during seed dormancy and germination. Methods We used the four kinds of commonly-used protein extraction methods for the experiment, including Tris-HCl extraction method, trichloroacetic acid (TCA) /acetone precipitation method, direct lysis buffer method and improved Tris-saturated phenol method. The obtained proteins were quantified, and then were analyzed by sodium dodecyl sulphate- polyacrylamide gel electrophoresis (SDS-PAGE) . Results The protein yield was the highest when using direct lysis buffer method, which was mainly composed of small molecule protein. The protein yield was the lowest using Tris/HCl method, characterized by the diffused stripes in SDS-PAGE spectra. The protein yield was moderate using TCA/acetone method and improved Tris-saturated phenol method, and the obtained protein by the TCA/acetone method had less stripes in SDS-PAGE spectra than that by Tris-saturated phenol method, and was characterized by macromolecular protein. Conclusion The combination of direct lysis buffer extraction method and improved Tris-saturated phenol method may provide reference for seed protein extraction method of two-dimensional electrophoresis for Amomum villosum Lour..

Objective:To investigate the clinical value ofplatelet distribution width ratio (RDW) and neutrophil lymphocyte ratio (NLR) in the prediction of coronary no reflow in patients treated with acute percutaneous coronary intervention (PCI).Methods:66 patients underwent emergency PCI treatment in our hospital from January 2016 December 2016 were selected as the research object,RDW and NLR of the patients before treatment were detected,and coronary no reflow phenomenon after emergency PCI rate were statistically calculated.RDW and NLR of patients with no reflow and normal blood flow were compared,the relationship between RDW and NLR with no reflow and the value of them predicting coronary no reflow were analyzed.Results:The incidence of coronary no reflow after emergency PCI was 30.30% (20/66).Compared with patients with normal blood flow,the RDW and NLR of patients with coronary no reflow were elevate (P<0.05).Spearman correlation analysis results showed that RDW and NLR were positively correlated with coronary no reflow (r=0.826,0.878,P<0.05).Further ROC curve analysis showed that AUC of preoperative RDW combined with NLR predicting the postoperative coronary no reflow in patients treated with emergency PCI were higher than RDW and NLR alone.Conclusion:RDW and NLR in patients treated with emergency PCI were closely related to the postoperative coronary no reflow,which might be used as reference index for evaluation of coronary no reflow after emergency PCI.

The construction of work style is related to the image of the Party and the government,the success or failure of the cause,and is a strategic task of the Party's construction.This article starts from the actual work of public hospital style con-struction,combines responsibility implementation,system construction,especially the practice and effectiveness of project-based management in key areas,reflects the exploration and construction of a long-term mechanism for hospital style construction by Nantong Cancer Hospital in Jiangsu Province,clarifies the target path,and explores a set of supervision work mechanism that is in line with the actual development of public hospitals,To provide strong political support for the hospital's further high-quality development under the current situation.
