Objective To detect the expression of CD 44 +/CD24 -and E-cadherin and vimentin in non-small cell lung cancer and its clinical prognostic relevance .Methods By immunohistochemistry , detecting , 500 cases of non-small cell lung cancer E -cadherin ,Vimentin and CD44 +/CD24 -expressions′correlation ,we analyzed the relationship with non -small cell lung cancer .Results In non-small cell lung cancer , vimentin was related to tissue differentiation,TNM staging(P<0.05);there was relationship between CD44 +/CD24 -and EMT by E-cadherin expression(P <0.05);CD44 +/CD24 -expression was related to lymph node metastasis , differentiation(P<0.05);their expressions were not obviously related to age ,sex,smoking history,clinical patho-logical type .The survival time of CD44 +/CD24 -high expression in NSCLC was significantly shorter than lower expression in NSCLC(P<0.05).Conclusion EMT malignant phenomenon raises cancer stem cells ,which can lead to the development of malignant cells poorly differentiated trends ,they are not an isolated process;important role in the development of EMT and CD 44 +/CD24 -union occurs in non -small cell lung cancer and prognosis with patients ,which provides a potential breakthrough in the treatment of cancer prevention and treatment targets .

Objective In order to understand the influence of disease uncertainty to emotion among advanced lung cancer chemotherapy patients, in order to guide the clinical nursing work. Methods A total of 146 advanced lung cancer chemotherapy patients were selected as the research object, using the general information, Disease Uncertainty Scale and Brief Profile of Mood States Scale for investigation. Results The disease uncertainty scores of advanced lung cancer chemotherapy patients were 77.91 ± 16.87; scores of emotion was 39.37 ± 18.72; they were positively correlated (r=0.363,P<0.01). Patients′family per capita income, cultural degree, two dimensions of disease uncertainty (uncertainty, poor information) were the main influencing factors of emotion (t=-4.947-4.603, P<0.05). Conclusions Advanced lung cancer chemotherapy patients with the higher level of disease uncertainty have more bad emotion. The patient's family per capita income level, cultural level and disease uncertainty will affect the mood of patients. Targeted intervention measures should be taken to reduce the patient′s disease uncertainty, and improve the patient′s emotion, improve the quality of life.
