Anthropogenic activities usually contaminate water environments, and have led to the eutrophication of many estuaries and shifts in microbial communities. In this study, the temporal and spatial changes of the microbial community in an industrial effluent receiving area in Hangzhou Bay were investigated by 454 pyrosequencing. The bacterial community showed higher richness and biodiversity than the archaeal community in all sediments. Proteobacteria dominated in the bacterial communities of all the samples; MarineGroupⅠand Methanomicrobia were the two dominant archaeal classes in the effluent receiving area. PCoA and AMOVA revealed strong seasonal but minor spatial changes in both bacterial and archaeal communities in the sediments. The seasonal changes of the bacterial community were less significant than those of the archaeal community, which mainly consisted of fluctuations in abundance of a large proportion of longstanding species rather than the appearance and disappearance of major archaeal species. Temperature was found to positively correlate with the dominant bacteria, Betaproteobacteria, and negatively correlate with the dominant archaea,MarineGroupⅠ; and might be the primary driving force for the seasonal variation of the microbial community.

Occurrence and distribution of antibiotic resistance genes in the sediments of the East China Sea bays

The coastal area of the East China Sea has experienced rapid urbanization and industrialization in China since 1980 s, resulting in severe pollution of its *** resistance genes(ARGs) are regarded as a kind of emerging pollutant with potential high risk. The sediment samples were collected from Hangzhou Bay(HB),Xiangshan Bay(XB), and Taizhou Bay(TB) to investigate the spatial occurrence and distribution of 27 ARGs and class I integron–integrase gene(intI1) in the coastal area of the East China Sea. The PCR results showed the frequent presence of 11 ARGs and intI1 in the sediments of the three bays. The qPCR results further showed that sulfonamide resistance was the most prevalent ARG type and antibiotic target replacement and protection were the most important resistance mechanisms in the sediments. Regarding the subtype of ARGs, sulI, tetW, and dfrA13 were the most abundant ARGs, in which sulI was higher in TB(based on both the absolute and relative abundances) and dfrA13 was higher in HB(based on the relative abundances). The network analysis revealed that intI1 had significant correlations with tetC, sulI, sulII, and blaPSE-1. Oil was the key connected factor, which had positive connections with sulI, sulII, and blaPSE-1. In addition, the joint effect of heavy metals and nutrients & organic pollutants might be crucial for the fate of ARGs in the coastal sediments.

目的探讨血小板-白蛋白-胆红素指数(PALBI)联合AIMS65评分对肝硬化并发急性上消化道出血(AUGIB)患者入院后6周内再出血及死亡的预测价值。方法选取2021年2月—2022年10月在锦州医科大学附属第一医院住院治疗的肝硬化并发AUGIB患者238例,所有纳入患者均随访6周,根据预后情况分为死亡组(n=65)和生存组(n=173)、未再出血组(n=149)和再出血组(n=89)。收集患者的一般资料及实验室指标(血常规,肝、肾功能及凝血指标等),计算入院时的PALBI评分、AIMS65评分、Child-Turcotte-Pugh(CTP)评分、终末期肝病模型(MELD)评分。计量资料两组间比较采用成组t检验或Mann-Whitney U检验;计数资料两组间比较采用χ2检验。采用多因素Logistic回归模型分析肝硬化并发AUGIB患者入院治疗后6周内死亡或再出血的危险因素。通过受试者工作特征曲线(ROC曲线)及曲线下面积(AUC)评估各评分系统的预测效能;AUC的比较采用DeLong检验。结果死亡组和生存组患者比较,呕血、既往有静脉曲张病史、Alb、TBil、INR、Cr、PT、收缩压、PALBI评分、AIMS65评分、CTP评分和MELD评分差异均有统计学意义(P值均<0.05);多因素Logistic回归分析结果显示,呕血(OR=4.34,95%CI:1.88~10.05,P<0.001)、既往有静脉曲张病史(OR=3.51,95%CI:1.37~8.98,P=0.009)、PALBI评分(OR=4.49,95%CI:1.48~13.64,P=0.008)及AIMS65评分(OR=3.85,95%CI:2.35~6.30,P<0.001)是患者死亡的独立危险因素;各评分预测生存情况的ROC曲线结果显示,CTP评分、MELD评分、PALBI评分、AIMS65评分、PALBI联合AIMS65评分的AUC分别为0.758、0.798、0.789、0.870、0.888,其中PALBI联合AIMS65评分的AUC明显高于4种评分单独预测的AUC(P值均<0.05)。再出血组和未再出血组患者比较,呕血、糖尿病病史、Alb、TBil、INR、Cr、PT、PALBI评分、AIMS65评分、CTP评分和MELD评分差异均有统计学意义(P值均<0.05);多因素Logistic回归分析结果显示,PALBI评分(OR=2.41,95%CI:1.17~4.95,P=0.017)和AIMS65评分(OR=1.58,95%CI:1.17~2.15,P=0.003)是患者再出血的独立危险因素;各评分预测再出血的ROC曲线结果显示,CTP评分、MELD评分、PALBI评分、AIMS65评分、PALBI联合AIMS65评分的AUC分别为0.680、0.719、0.709、0.711、0.741,PALBI联合AIMS65评分的AUC最大(P值均<0.05),但特异度较低。结论PALBI评分联合AIMS65评分对肝硬化并发AUGIB患者入院后6周内的死亡具有一定的预测价值,优于CTP评分及MELD评分单独检测;对6周内再出血预测价值较低,准确性一般。
