Objective To study the effects of hypoxia on adhesion and migration of ovarian carcinoma cell line Caov-3 in vitro. Methods The ovarian carcinoma cell Caov-3 was cultured under normoxic condition or in hypoxic condition. In vitro adhesion of Caov-3 on extracellular matrix fibronectin and matrigel was detected using MTT colorimetric assay. In vitro migration of Caov-3 on extracellular matrix matrigel was assayed with cellular migration test. Results In vitro cell adhesion experiment showed that, compared with the control cells, hypoxia increased cell adhesion to extracellular matrix matrigel and fibronectin by 17.1% and 15.2%, respectively. There were significant differences between the normal conditions and hypoxia (P

Objective To provide basis for the formulation of policies and measures that will reduce the work pressure on nurses and to provide them with a better working environment. Methods An investigation was made via questionnaires into 942 nurses working in designated SARS hospitals and a comprehensive analysis was conducted by means of multivariant stepwise regression. Results The major factors affecting the pressure on nurses include: lack of support from and communications with families, arduousness of tasks to an unbearable point, extreme strictness in management, and unsoundness of treatment and living conditions. Conclusion Good communications with families are of great significance to nurses working in isolated areas. It is imperative to rationally allocate the human resources of nurses, show more concern for them, encourage them to participate in management, and strengthen scientific prevention so as to create a better working environment.

Objective To investigate multiparametric immunophenotypic features in patients with acute myelocytic leukemia(AML)-M_2 bearing AML-1/ETO gene rearrangements and its predicting value.Methods A multiparametric flow cytometry was used in the study of phenotypic characterization of the subtype of AML.Immunophenotype of 30 patients with AML(M_2/ETO~+)was analyzed by fluorescence in situ hybridization(FISH).The results were compared with 36 patients of AML-M_2 with AML-1/ETO~- (M_2/ETO~-)and 34 acute promyelocytic leukemia(APL)patients.Results There were a population. 15.89%-68.53% the blast cell and a population of more differentiated and heterogeneous myeloid cells in the marrow of 30 patients with M_2/ETO~+.The blast cells had a myeloid phenotype(CD_(33),CD_(13)and MPO) and showed a characteristic pattern of antigen expression.The fluorescent intensity of CD_(33)in patients with M_2/ETO~+ was less than in patients with M_2/ETO~-and APL [ mean fluorescent intensity(MFI):98?75 v. 244?184 and 845?523,both P

This paper presents a case of post-pancreatitis diabetes mellitus with seriously damaged islet function. The blood glucose level was successfully controlled by continuous subcutaneous insulin infusion ( CSII )therapy both in short and long terms.

Basal rate verification is the process to find and verify the basal rate of continuous subcutaneous insulin infusion (CSⅡ) required for basal glucose metabolism.In the present study,five cases of brittle diabetes were treated by CSⅡ with Insulin Lispro.After doses were adjusted to reach steady blood glucose levels,basal rate verifying tests were carried out.The results showed that the overall level and stability of blood glucose were improved markedly after CSⅡ.Before and after the verification of the basal rate,there was no significant difference in CSⅡ total doses.Basal rates decreased from 50％ of total to 30％ (P＜0.05),and boluses increased to 70％ (P＜0.05).The basal rates during lunch and supper time were reduced by half (P＜0.05),the boluses of lunch and supper were increased 1.5 times (P＜0.05),and square waves were needed to control postprandial blood glucose.These results suggest that the CSⅡ could smoothly control blood glucose level in brittle diabetes without basal rate verification.However,the implementation of the verification could better determine the basal rates for basal glucose metabolism,and thus help to identify diet-related boluses.

OBJECTIVE To analysis the effect of air disinfection by using nanometer light catalysis decontamination machine in operating room. METHODS By compare the effectiveness of air disinfection both by using nanometer light catalysis decontamination machine and ultraviolet rays light. RESULTS The result of tests is 0 CFU/m~2 by nanometer light catalysis decontamination machine and 33.3 CFU/m~2 by ultraviolet rays light in unmanned environment;By different groups: F=220.423,P=0.000,P

Objective:To understand the anxiety and depression status of junior standardized training nurses and its influencing factors,to explore the humanistic care strategies for anxiety and depression,and thus to provide the basis for improving the psychological state of the nurses and the content of standardized training.Methods:Across-sectional questionnaire survey were conducted among 161 standardized training nurses in one Three-A hospital using Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS).Results:The positive rate of depression and anxiety in 161 standardized training nurses were 51.60％ and 34.70％,respectively.The coarse average scores of depression and anxiety were (39.73 ± 8.55) and (37.21 ± 8.64),respectively,which were higher than Chinese norm (33.46 ± 8.55) and (29.78 ± 6.46) (P ＜ 0.05).Family burden,clinical profes-sional knowledge and skills and work environment had influences on depression;family burden and the differences of rotation departments had influences on anxiety.Conclusion:The formulation of content of standardized train-ing should consider the different characteristics of rotation department.We should create a good working atmo-spherefor standardized training nurses,improve the training of professional knowledge and skills on the basis of paying attention to humanistic care,strengthen the training of psychological quality and psychological counseling.
