为了探讨肝激酶B1(LKB1)蛋白在食管鳞癌组织中的表达水平及其与食管鳞癌临床特征及生存期的关系,应用免疫组化方法检测120例食管鳞癌患者组织中LKB1蛋白表达情况并对诸多临床特征进行相关性分析研究,发现LKB1蛋白在食管癌旁正常组织的阳性表达率高于癌组织;LKB1蛋白表达与患者年龄、性别、肿瘤部位、病变长度及浸润深度无关而与分化程度、淋巴结转移及临床分期(TNM)相关,且LKB1蛋白阴性组预后较阳性组差.可见LKB1视为抑癌基因影响食管鳞癌的预后,可能成为食管鳞癌新型的临床预后指标之一. 相似文献

Parents of children with Type 1 diabetes (T1D) experience high levels of distress, which may negatively impact child functioning. However, little is known about mechanisms that may buffer the adverse impact of parental distress. The current study explored the possible buffering role of maternal adaptive cognitive emotion regulation (CER) for the relationship between maternal distress and child psychological functioning. Forty-three children with T1D (8–15 years) completed measures assessing trait anxiety and depressive symptoms. Their mothers reported on general distress, illness-related parenting stress, and adaptive CER. Maternal illness-related parenting stress (but not general distress) was significantly associated with child psychological functioning. No buffering role for maternal adaptive CER was observed. As the current study is rather preliminary, future research using other methods to examine maternal adaptive CER, and examining other parental variables that may buffer against the negative impact of parental distress is warranted. 相似文献

The transition to parenthood is a period of both joy and challenge for most parents. There is a recognized need to support parents during this period, yet existing interventions have shown limited evidence of efficacy. This study takes a consumer‐focused approach to examine the needs and preferences of parents both prenatally (n = 77) and postnatally (n = 123) for parenting support. The study used a cross‐sectional design with a purpose‐built online survey. Parents were recruited via online forums, Facebook and parenting blogs, childcare centers, and playgroups. In general, all parents were satisfied with their current levels of both formal and informal support, and about one fourth of parents had accessed a parenting intervention. Parents expressed a moderate level of interest in additional parenting information, and parents expecting their first baby indicated preferences for information about basic baby care needs whereas postnatally, parents expressed more interest in topics around self‐care and behavior management. The implications for developing interventions and engaging families are discussed. 相似文献
