Objective To investigate the general self-efficacy of the clinical nurses and explore the relationship between general self-efficacy and job burnout .Methods 473 clinical nurses from 13 hospitals of the third and the second grade in Leshan city were recruited and investigated with general self-efficacy scale and mashach burnout inventory .Results (1)The mean score of the clini-cal nurses′general self-efficacy was(2 .63 ± 0 .49) scores ,which was lower than that of military nurses (2 .69 ± 0 .58) scores (P<0 .05) .(2)There was a significant difference of nurses′general self-efficacy in different employment types ,administrative positions , marital statuses ,length of service and professional titles (P<0 .05) .(3)The score of general self-efficacy was negatively correlated with that of emotional exhaustion and of depersonalization (P<0 .01) ,but positively correlated with that of personal accomplish-ment(P<0 .01) .Conclusion Nurses′overall general self-efficacy was at a moderate level .Administrators could reduce nurses′job burnout more effectively by improving their self-efficacy .

Changes in SOM-like neurons of the hippocampal formation were investigated inWistar male rats(young-2 months old;adult-10 months old;aged-24 months old)by using the combination of the IGSS method and image quantitative analysis.The following results were obtained:1.Number of SOM-like neurons decreased markedly(P

Objective To analyse the fusion genes derived from chromosome structural aberrations in acute myeloid leukemia(AML) and the relationship between fusion genes and the MICM classification, clinical diagnosis, chemotherapy and prognosis. Methods The expression of fusion gene in bone marrow samples was detected with multiplex RT-PCR technique and chromosome karyotypes, immunological phenotypes and clinical data were analyzed in 60 acute myeloid leukemia newly diagnosed. Results 37 cases(61.67 %) of 60 patients carried 5 kinds of fusion genes consisting of MLL-AF9, TLS-ERG, CBFβ-MYH1, AML1-ETO and PML-RARα. The activation of oncogene HOX11 was detected in 13 AML cases, three of them with other chromosome aberration simultaneously.23 cases of 31 patients carrying AML1-ETO or PML-RARα, reached complete remission(CR) after chemotherapy and without relapse. Conclusion Gene typing is the most precise classification method that can direct clinical treatment and evaluate prognosis. Multiplex RT-PCR technique, which can quickly screen 29 kinds of fusion gene derived from chromosome structural aberrations at one time, maybe helpful to improve M1CM classification and guide the choice of treatment.

Objective To explore the deletion of chromosome 13 in multiple myeloma (MM), clinical significance of FISH-defined partial deletion chromosome 13 in MM patients were investigate. Methods Fluorescence in situ hybridization (FISH ) was performed on bone marrow from 38 patients with MM to study the deletion of Rb-1 gene and locus 13q14 on chromosome 13. Fisher exact propability was used to study the relations between partial deletion of chromosome 13 and clinical features. Results 20 out of the 38 cases were found with deletion of chromosome 13; deletion of Rb-1 gene in 4 cases; deletion of locus 13q14 in 2 out of 38 cases; and 14 cases with both of deletions. Fisher exact propability showed that deletion of chromosome 13 was associated with hypso-serum lactic dehydrogenase, stage of ISS. Conclusion Deletion of Rb-1 gene and locus 13q14 were both common cytogenetic changes in MM patients with effect on the biological behavior of the disease, but the value of del (13q14) in MM needs further investigation. FISH was a rapid, accurate and sensitive technique in the analysis of del (13q14) in MM.

Objective To detect expression of TEL-AML1 fusion genes in pediatric cases with acute lymphoblastic leukemia(ALL) and discuss the role of reverse transcriptase polymerase chain reaction(RT-PCR)and fluorescence in situ hybridization(FISH) in detection of t(12 ;21) and the clinical significance. Methods TEL-AML1 fusion gene was identified in bone marrow munonuclear cells from 31 newly diagnosed childhood ALL patients by NRT-PCR, FISH and conventional cytogenetic analysis (CCA). Results TEL-AML1 fusion gene was found in 7 out of 31 cases, accounting for 22.6 % in pediatric ALL, and 7 out of 31 cases accounting for 25.9 % in B-ALL Seven cases were found with t (12;21) by FISH and NRT-PCR. The incidence of the t(12;21) was 22.6 % in newly diagnosed pediatric ALLs. Conclusion It is concluded that TEL-AML1 rearrangement is a frequent molecular abnormality in childhood ALL. t(12;21) is the most common cytogenetic translocations in Chinese pediatric ALLs, but it is always difficult to identify by routine CCA.Other molecular methods, e.g. NRT-PCR and FISH are powerful in detecting such a critical genetic translocation.

Objective To evaluate reference range for fasting venous blood cells in the healthy 51 584 elderly people from Shuyang,China.Methods Totally 1000 non-old people and 51 584 elderly people were involved in this study.Fasting venous blood cells were collected from each group of subjects using standard procedures.The collected aliquots were processed according to standard operating procedures to determine participants' complete blood counts.Non-parametric methods were employed to calculate the reference intervals and 95 ％ confidence intervals for complete blood counts by Sysmex XE-2100 blood cell analyzer.Results The reference ranges of fasting venous blood cells in elderly subjects (male,female) were [(3.25-9.45) × 109/L and (3.35-9.39) × 109/L,WBC];[(3.87-5.55) × 1012/L and (3.71-5.19) × 1012/L,RBC] ; [(116.2-169.5)g/L and(107.4-153.6)g/L,Hb] ; [(37.2-52.4) ％ and(35.2-48.6) ％,HCT] ; [(86.3-104.8)fl and (85.2-103.5) fl,MCV] ; [(27.0-33.4) pgand(26.4-32.5)pg,MCH]; [(297.1-335.4)g/L and(293.3-330.5)g/L,MCHC];[[(38.4-54.2) and (38.6-52.9),RDW-SD]; [(11.3-15.4)％ and(11.4-15.3)％,RDW-CV];[(98.8-303.8) × 109/L and (109.9-334.8) × 109/L,PLT] ; [(1.10-3.42) and (1.20-3.78) ml/L,PCT];[(11.2-15.6) fl and(11.3-15.5)fl,MPV]; [[(8.89-16.7)％ and(9.48 17.1)％,PDW];[(20.3-49.1) ％ and (20.5-48.6) ％,PLCR],respectively.13 parameters of fasting venous blood samples in elderly people had statistically significant differences compared with non-old people (all P ＜0.05).Conclusions The reference range of fasting venous blood samples in elderly people are significantly different from non-old people.It is necessary to scientifically and reasonably establish the reference ranges for fasting venous blood cells in local elderly people.
