RESUMO
OBJECTIVE@#To investigate the phenotypes and gene frequencies of Kell blood group system K antigen and Rh blood group system D antigen in Xinjiang, and summarize and understand the distribution of Kell(K) blood type and Rh(D) blood type in this area.@*METHODS@#A total of 12 840 patients who met the inclusion criteria during physical examination and treatment in our hospital and 18 medical institutions in our district from January 1, 2019 to December 31, 2019 were collected for identification of Kell blood group system K antigen and Rh blood group System D antigen, and the distribution of K and D blood groups in different regions, genders and nationalities were investigated and statistically analyzed.@*RESULTS@#The proportion of K positive in the samples was 1.39%, the highest was 1.91% in southern Xinjiang, and the lowest was 1.03% in northern Xinjiang(P<0.01). The proportion of Rh(D) negative samples was 2.75% and the gene frequency was 16.64%. The proportion of Rh(D) negative samples was 4.03% and the gene frequency was 20.10% in southern Xinjiang, followed by eastern Xinjiang and the lowest in northern Xinjiang (P<0.01). The frequency of K antigen in Uygur nationality was the highest, reaching 2.16%, Kirgiz 1.54%, and the distribution trend of D/d antigen was similar to that of K antigen. Among women, the K positive frequency of Kazak nationality was slightly higher than that of Mongolian nationality. The highest proportion of K positive in Uygur women was 2.38%, which was higher than that in Uygur men (1.86%). The frequency of d phenotype in Kazak women was 3.15%, which was higher than that in Kirgiz （2.89%） (P<0.01).@*CONCLUSION@#The distributions of Kell(K) and Rh(D) blood groups in northern and southern Xinjiang and eastern Xinjiang had its own unique characteristics and differences. There are significant differences in blood group distribution among different ethnic groups and gender groups. In the future, k antigen detection can be included to further improve the investigation on the distribution of Kell blood group system in this region.

Objective: According to theory of Chinese medicine property, the ecological environment shapes properties (natures and flavors) of Chinese materia medica (CMM) and there are close relationships between certain natures and flavors. However, to date these observations have not been validated scientifically in the context of the whole flora of a region. The present study aims to address this gap. Methods: We collected geographical distributions of 3637 vascular plant species native to the Xinjiang region of northwest China, of which around 812 are medicinal plants. The CMM property characters of these medicinal plants were also collected. All medicinal plants were then analyzed in the occurrence of their natures (cold, cool, neutral, warm, and hot) and flavors (sweet, bitter, sour, salty, and pungent). Possible correlations between these properties and environmental factors, notably climate, as well as correlations with plant species richness of the wider native flora of Xinjiang were then investigated using permutation test and regression. Results: Cold species (38.5%) were more numerous than warm (21.0%) and neutral (22.3%), while bitter species (43.3%) were more numerous than pungent (25.6%), sweet (22.4%) and sour (6.7%) ones. Species with bitter flavor were most commonly also cold (48.6%) in nature, sour flavor usually coincided with cold (44.2%) or cool nature (26.0%), whereas pungent or sweet species tended to be warm (34.4%, 28.4%) or neutral (27.8%, 28.4%). The percentages of species of cold/cool nature, bitter flavor were higher in mountainous regions, and the percentages of warm/neutral and pungent/sweet/sour were higher in basins. The percentages of species of cold/cool, bitter were positively correlated with actual evapotranspiration (AET), and also plant species richness but had a bell-shaped relationship with potential evapotranspiration (PET), whereas the inverse situation was shown for warm/neutral and pungent/sweet/sour species. Conclusion: Analysis of the data in Xinjiang region of China supports the qualitative observations concerning natures and flavors in traditional theory of Chinese medicine property. Specifically, (i) certain natures and flavors co-occur more frequently than if randomly distributed; (ii) correlations between proportions of natures and flavors and climatic variables suggest a role for the environment in shaping the properties of CMM.
RESUMO
Objective To understand the development status of healthcare-associated infection (HAI)management organizations in Xinjiang region,and effectively improve the management level of HAI in Xinjiang.Methods 101 secondary and above medical institutions in Xinjiang were selected by cluster random sampling method,a retrospec-tive survey was conducted from February 15 to March 31,2016.Development of HAI management organizations in each hospital in 1995,2000,2005,2010,and 2015 were surveyed,statistical analysis of the surveyed results were conducted.Results Of 101 hospitals,22 were tertiary hospitals,79 were secondary hospitals.In 2005 and before, more than 70% of hospitals with >300 beds and 20% of hospitals with300 beds and less than 5% of hospitals with 50% of full-time professionals received secondary vocational school and below education,in 2005 and after,about 80% of full-time professionals received at least college and above education;in 2000 and before,> 70% of full-time professionals didn’t receive training.In 2015,the percentage of nursing staff engaged in HAI management dropped to 65.90%,and doctors and other professionals both accounted for 17.05%,40.09% of HAI management professionals received university education,92.08% par-ticipated in autonomous region level and above training,1.98% didn’t receive training.Conclusion HAI infection management organizations in Xinjiang region in the past 20 years have developed,the allocation of professionals and professional quality can not meet the needs of HAI infection management in this region.
RESUMO
Twenty-eight moderately halophilic bacteria isolated from salt lakes in Xinjiang Regions were analyzed by 16S rDNA PCR-RFLP in comparison with nine reference strains of related species. The 16S rRNA PCR products of the tested stains were digested by four restriction enzymes (AluI, HinfI, RsaI and HaeⅢ). The results showed that all tested strains were clustered into three groups at 74% similarity level. Group I included 2 reference strains Chromohalobacter marismortui, Nesterenkonia halobia and new isolate CI. Group Ⅱ included seven type strains belonging to Halomonas and eight new isolates. Group Ⅲ included ninteen new isolates.
RESUMO
Twenty nine moderately halophilic bacteria isolated from salt lakes in Xinjiang Region were compared with nine reference strains of relative species by performing a numerical analysis of 112 phenotypic characteristics. All the new isolates are Gram negative and can grow on the media containing 0～25% NaCl. The results showed that all tested strains were clustered into 2 phena at 76 % similarity level. Phenon I was composed by 25 new isolates strains,and phenon II included 9 reference strains and 4 new lsolated strains. Most of the new isolated strains were clusted into 3 subphena at 86 % similarity level. There were 10 new isolated strains in subphenon 1, 8 new isolated strains in subphenon 2, and 1 new isolated strain and 5 reference strains were included in subphenon 3. The results indicated that there were great differences between the new isolates and the reference strains.
