泌尿系统感染是临床常见的感染性疾病,在医院感染中仅次于呼吸道感染,占第二位 [1] 。泌尿系统感染如果能够得到及时有效的治疗,效果显著,但随着抗菌药物的广泛应用,细菌对抗菌药物的耐药性逐年增加,耐药细菌引起的泌尿系统感染给临床治疗带来更大的难题 [2] 。本文对近年我院尿培养中分离细菌的分布及耐药性进行研究,为临床诊治提供重要依据。1材料与方法1.1菌株来源2016年10月至2017年10月我

卵巢癌和宫颈癌是女性生殖器官恶性肿瘤之中最常见的,其中卵巢恶性肿瘤的发病率处在第三位,第一位为子宫颈癌,第二位为子宫体癌,卵巢癌对妇女的生命健康造成极其严重的威胁.有大量的研究数据证明,肿瘤标志物的早期发现与卵巢癌的预后有重要的关系,本文就卵巢癌的肿瘤标志物进行综述.

Objective To investigate the expression and significance of CNN1 in colorectal cancer and adjacent tis-sues.Methods Two-dimensional chromatography and mass spectrometry were used to detect the different proteins of colorectal cancer,in addition,the expression of diferential proteins were verified by Western blot.Results Forty-four differentially expressed proteins were detected in colorectal cancer based on the corresponding non-tumor normal tis-sues,and 23 of them were down-regulated,in which,CNN1 was one of the down regulated proteins.Conclusion The low expression of CNN1 has a relationship with a varity of cancers,including colorectal cancer,so CNN1 may play a role as a cancer suppressor.
