【Objective】 To explore the status and characteristics of voluntary blood donors in rural areas of Dali Bai Autonomous Prefecture (referred as Dali), and to provide basis for scientific and effective voluntary blood donation in rural population in regions inhabited by ethnic groups. 【Methods】 The data of rural blood donors who donated blood in Dali from 2010 to 2019 were collected, including demographic data as nationality, gender, age, educational background, as well as the blood donation frequency and blood infection screening (index) results. The above data of urban blood donors who donated blood in Dali during the same period were selected to investigate the increasing trend of blood donation rate. SPSS26.0 was used for statistical analysis of the collected data of rural and urban blood donation population. 【Results】 From 2010 to 2019,the number of blood donors in Dali increased from 13 949 to 19 479,with an increasing rate of 39.64%. The number of rural blood donors increased from 2 623 to 8 727,among which the number of ethnic minority groups increased from 1 779 to 5 059.The ratio of male to female blood donors was 70.30% (1 844/2 623) vs 29.70% (779/2 623) in 2010,56.37% (4 919/8 727) vs 43.63%(3 808/8 727) in 2019. Those with educational level of junior middle school or below were the most, accounted for 43.97%(38 443/85 836),with ethnic donors of 24.47%(23 583/85 836). The proportion of donors aged between 36 and 45 was the highest[40.73% (30 477/74 827) ], with ethnic donors of [28.56% (21 374/74 827), and the proportion of repeated blood donors was 54.87%(35 279/64 299),with ethnic donors of 49.89%(18 080/36 240) [the proportion of repeated blood donors in urban donors in the same period was 48.13% (55 677/115 675) ] (P<0.01). The unqualified rate of ALT was the highest [1.21%(1 272/105 489) ] [The unqualified rate in local donors was 1.99%(3 837/192 552) ] (P<0.01), and that of the ethnic donors was 1.51%(358/56 718). There was no significant difference in the unqualified rates of HB-sAg, anti-HCV, anti-HIV and anti-TP among urban and rural blood donors (P>0.05). 【Conclusion】 It is of great significance to explore the characteristics of blood donors in rural areas (especially regions inhabited by ethnic groups) and the reasons for disqualification, in order to scientifically carry out the recruitment of voluntary blood donors and further promote blood donation for rural residents

Genus Polygonatum,belonging to the Liliaceae family,is mostly medicine food homology species,which have been documented as treating " dry mouth,less food,and internal heat and thirst" in medical ancient books. In traditional Chinese medicine clinic,it was used to treat diabetes,hyperlipemia and asa rehabilitation therapy of cancer. With deepening the basic research and industrial development of this genus,the bioactive component groups and their action mechanisms of prevention and treatment of diabetes and diabetic complication continue to be revealed. By consulting ancient Chinese herbal medicine and modern literature,the research on the herbology,material basis and mechanism of the genus Polygonatum were reviewed. The result indicated that the plants of Polygonatum were used for the treatment of diabetes,based on the ancient herbal literature and modern research,the polysaccharides,flavonoids and saponins were their active ingredients. Among them,the significant chemical constituents of decreasing blood glucose were Polygonatum polysaccharides,and the flavonoids and saponins also have this function. Although some scholars have studied the anti-diabetic efficacy and material basis of genus of Polygonatum,the pharmacodynamics,mechanism and metabolic pathways are not clear. Therefore,further strengthening of the related research of genus of Polygonatum,especially use of modern scientific and technological research to clarify the material basis of its efficacy,and mechanisms,are crucial to accelerate the modernization and development of anti-diabetic drugs and utilization of genus of Polygonatum.

OBJECTIVE：To study the mechanism of Periplaneta americana extract degreasing cream and CⅡ-3（shorted for “degreasing cream ”and“CⅡ-3”）reversing the multi-drug resistance of human HepG 2/ADM cells. METHODS ：MTT assay was used to investigate the toxicity effects of different concentrations of sorafenib （positive control ），degreasing cream and C Ⅱ-3 on HepG2/ADM cells ，then IC 20 was calculated. The experiment was divided into sensitivity drug ，drug-resistance group ，sorafenib group，degreasing cream group and C Ⅱ-3 group. HepG 2 cells were included in sensitivity group ，and HepG 2/ADM cells were included in the latter 4 groups. Sensitivity group and drug-resistance group were treated with routine medium ，and other 3 groups were treated with relevant medicine （IC20 as drug concentration ）. The content of ADM in HepG 2/ADM cells was determined by Laser scanning confocal microscopy. The expression of apoptosis-related protein as Bcl- 2 and Cleaved-Caspase- 9 p37 were detected by Western blotting assay. RT-qPCR and immunocytochemistry were adopted to detect mRNA and protein expressions that related to multidrug resistance [P-gp （expression produce of MDR1 gene），LRP，BCRP] and that related to enzyme-mediated multidrug resistance pathway （GST-π and Topo Ⅱ）. RESULTS ：The IC 20 of degreasing cream ，CⅡ-3 and sorafenib were （2.40±0.16）， （200.44±27.52），（18.00±1.82）μg/mL，respectively. Compared with sensitivity group ，the protein expressions of Bcl- 2，P-gp， LRP，BCRP and Topo Ⅱ，the mRNA expressions of MDR 1， LRP，BCRP and GST-π were increased significantly in drug resistance group （P＜0.05 or P＜0.01）. Compared with @qq.com drug-resistance group ，the mRNA and protein expression of MDR1 mRNA and LRP ，BCRP，GST-π were significantly decreased in degreasing cream group and C Ⅱ-3 group（P＜ 0.05 or P＜0.01）；the protein expression of Bcl- 2 and the mRNA expression of Topo Ⅱ were significantly decreased （P＜0.01）， while the protein expression level of Cleaved-Caspase- 9 p37 was significantly increased in C Ⅱ -3 group （P＜0.05）. CONCLUSIONS：Degreasing cream and C Ⅱ-3 can reverse multidrug resistance of HepG 2/ADM cells by reducing drug efflux ， promoting cell apoptosis ，reducing the mRNA and protein expression of multi-drug resistance gene as well as gene in enzyme-mediated multi-drug resistance pathway. The effect of C Ⅱ-3 is better than that of degreasing cream.

Objective·To isolate lipopolysaccharide (LPS) and capsular polysaccharide (CPS) from Porphyromonas gingivalis (Pg) and analyze their ability to induce THP-1 cells to secrete interleukin 8 (IL-8) in vitro. Methods·LPS and CPS were isolated from the polysaccharides by gel filtration chromatography, which had already been extracted from Pg ATCC33277 and SJD4. The isolated LPS and CPS from different strains were used to stimulate THP-1 cells in different doses and for different periods. The level of IL-8 in the cell culture suspension was measured by ELISA. Results·LPS and CPS were successfully separated from the polysaccharides in Pg ATCC33277 and SJD4. The relative molecular masses of LPS and CPS were 20000-50000 and 150000-500000, respectively. LPS and CPS could induce THP-1 cells to produce IL-8 in vitro in a time- and dose-dependent manner. The effect of LPS from ATCC33277 on secretion of IL-8 was greater than that of CPS with the dose of 0.1 μg/mL (P<0.05). However, the difference could only be found at 24 h in SJD4, and the effect of CPS was greater (P<0.05). Conclusion·As a component of polysaccharides extracted from Pg, CPS can induce THP-1 cells to secrete IL-8 in vitro in a time- and dose-dependent manner.
