Objective To verify the relationship between personality traits and clinical nurse competence in five third-A level hospitals in Shenyang. Methods A total of 1559 clinical nurses from five tertiary-level hospitals in Shenyang were recruited into this study. Two self-report questionnaires, the Nurse Competence Scale (NCS) and the Tridimensional Personality Questionnaire (TPQ), were used to collect data. Results The average score of NCS was 71.97 ± 13.25.Nursing competence increased with the increase of working years (β=0.272, P<0.01) and RD (β=0.134, P<0.01). Practicing nurses with the lower HA appear to have a higher level of competence (β=-0.117, P<0.01). Conclusions The overall level of nurses' competencies good in third-A level hospitals in Shenyang. The predicting factors of nursing competence are work experience, HA and RD. More psychological courses should be provided in fundamental nursing education and continuing nursing education for helping nurses shape their good personality traits.

Objective To evaluate the efficacy of chemoradiotherapy alone and prognostic factors for locally advanced rectal cancer. Methods The clinical data of 47 patients with locally advanced rectal cancer who were admitted to our hospital and mostly treated with chemoradiotherapy alone from 2003 to 2010 were retrospectively analyzed. Three of the patients received radiotherapy alone. The Kaplan?Meier method was used to estimate overall survival (OS), progression?free survival (PFS), and distant metastasis?free survival ( DMFS ) rates, and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox regression model was used for multivariate prognostic analysis. Results In all patients, the 3?and 5?year OS rates were 53?2% and 33?2%, respectively, while the 3?and 5?year PFS rates were 37% and 31%, respectively. During the follow?up, 15 patients (32%) had local progression with PFS of 1?60 months (median PFS, 14 months);23 patients (49%) had distant metastasis with DMFS of 2?60 months ( median DMFS, 17 months) . Patients treated with high?dose radiotherapy had significantly lower 3?and 5?year local progression rates than patients treated with medium?dose radiotherapy ( 11% vs. 54%;11%vs. 57%;P=0?004). After chemoradiotherapy, 9 patients (19%) had clinical complete response (cCR), and the 3?and 5?year OS and PFS rates in those patients were all 8/9. The univariate analysis indicated that tumor distance from the anus and cCR were influencing factors for prognosis ( P= 0?026;P= 0?000 ) . However, the multivariate analysis showed that cCR was the only influencing factor for survival ( HR=12?24;95% CI, 1?64 ?91?29;P= 0?015 ) . Conclusions Chemoradiotherpay or radiotherapy alone is effective and safe in the treatment of patients with locally advanced rectal cancer who have to give up surgery or have unresectable tumors. High?dose radiotherapy may improve local control rate. Complete response to chemoradiotherapy predicts satisfactory treatment outcomes.

Objective:To methodologically establish the lentivirus granule packaging, concentration and infection against CD34~+ cells from umbilical blood. Methods:The lentivirus system of the 3~(rd) generation was used to produce the virus. Ultrafiltration and ultracentrifugation were employed to concentrate virus. Several treatments were used to improve virus infection including in vitro amplification culture, facilitation of rest cells into cell cycle, promotion of cell adhesion and immobilization during infection, and repeat infection methods. Results:CD34~+ cells were not obviously changed by checking the expression level of CD34 marker on the cell surface after 48 h culture. After two-step concentration, virus titer was increased up to 5.06×10~7/ml, and the infection rate against CD34~+ cells from umbilical blood was increased up to 37.7%.Conclusion:Lentivirus supernatant with over 10~7/ml titer can be obtained using the above methods. Efficient infection against CD34~+ cells from umbilical blood can be achieved.

OBJECTIVE:
To study the interactive regulatory effect of histone acetylation and methylation on cardiomyogenesis, and to provide a theoretical basis for the prevention and treatment of congenital heart disease.
METHODS:
A total of 24 Kunming mice were randomly divided into embryo day 14.5 (ED 14.5) group, embryo day 16.5 (ED 16.5) group, postnatal day 0.5 (PND 0.5) group, and postnatal day 7 (PND 7) group, with 6 mice in each group, and the heart tissue of fetal and neonatal mice was collected. Colorimetry was used to measure the activities of histone acetylases (HATs) and histone methyltransferases (HMTs) in the myocardium. Western blot was used to measure the expression of H3K9ac and H3K9me3 in the myocardium.
RESULTS:
Colorimetry showed that the activities of HATs and HMTs were higher before birth and were lower after birth. There was a significant difference in the activity of HATs in the myocardium between the PND 0.5 and PND 7 groups and the ED 14.5 group (P<0.05), as well as between the PND 7 group and the ED 16.5 group (P<0.05). There was also a significant difference in the activity of HMTs in the myocardium between the PND 7 group and the ED 14.5 and ED 16.5 groups (P<0.05). Western blot showed higher expression of H3K9ac and H3K9me3 before birth and lower expression of H3K9ac and H3K9me3 after birth, and there were significant differences in the expression H3K9ac and H3K9me3 in the myocardium between the PND 0.5 and PND 7 groups and the ED 14.5 and ED 16.5 groups (P<0.05).
CONCLUSIONS
The dynamic expression of HATs, HMTs, H3K9ac, and H3K9me3 is observed during cardiomyogenesis, suggesting that histone H3K9ac acetylation and histone H3K9me3 methylation mediated by HATs and HMTs may play a role in interactive regulation during cardiomyogenesis.

BACKGROUNDIt is well recognized that meteorological factors have important infuences on the onset and development of many kinds of diseases. The present study was undertaken to investigate the effects of the meteorological elements on admission rates of cerebral infarction patients with hypertensive nephropathy at Changchun city, Jilin Province, northeast China.
METHODSA total of 763 medical records of inpatients from nine hospitals at Changchun city, during a period from April 6 to April 17 in 2010, were reviewed. These patients were admitted to hospitals due to the occurrence of cerebral infarction. The hypertensive nephropathy was evidenced with certain diagnosis of essential hypertension and hypertension-related kidney injuries. The cerebral infarction was diagnosed according to the World Health Organization (Stroke) standard. All the meteorological data were from practical monitoring records in Jilin Province Meteorological Observatory. The relationships between the epidemiological prevalence of cerebral infarction and meteorological variables were analyzed using the time series models of statistics.
RESULTSCompared with admission rates before the violent change in meteorological status (April 6 to April 17, 2010), the number of admission patients suffering from cerebral infarction remarkably peaked on April 12. Such an increase was highly correlated with heavy precipitation, elevation of daily average relative humidity, and reduction of average daily air temperature. With the betterment of the meteorological conditions on April 17, the admission rates of cerebral infarction patients dropped to the same level as the dates before snowing (April 6 to April 11).
CONCLUSIONSThe meteorological changes are highly associated with the occurrence of cerebral infarction in patients with hypertensive renal injury in northeast China. This study also suggested that an intensive medical interference for those patients with hypertension-induced organ injuries is very necessary in preventing the occurrence of cerebral infarction with hypertensive nephropathy when there is a violent change in meteorological condition.

The yeast fusant ZFF-28, which is high in biomass production and rich in selenium, was constructed after mutagenesis and protoplasts fusion between yeast strains. The total selenium content of ZFF-28 is 1.8 and 1.0 times higher than that of the parental strains Saccharomyces cerevisiae ZY-67 and Saccharomyces kluyveri SZY-198 respectively. Using single factor tests and a L16(4(3) x 2(1)) orthogonal design, the cultivation conditions was optimized as: 50mL culture in 250mL shake flasks in molasses containing 6% sugar and 60microg/mL Se at 28 degree C for 25h at 220 r/min, with the initial pH adjusted to 6.0 - 6.5. Under the optimized conditions, the biomass (dry weight) reached 8.2g/L and the Se content of the cells reached 2050microg/g, with organic and inorganic Se contents being 91% and 9% respectively.
