Objective To learn the status quo of core competency of registered nurses in tertiary level first-class hospitals in Liaoning Province and compare the level and characteristics of core competency of registered nurses in different working years in order to supply evidence to establish contrapuntal training protocol.Methods "The Competency Inventory for Registered Nurse scale"(CIRN,by LIU Ming)was distributed to investigate the core competency of registered nurses,the data underwent analysis.Results The overall score of core competency level was (174.11±31.89),the score of the nurses with 16～20 years of working experience was the highest,while the score of nurses working for 1～5 years was the lowest.The core competency varied with working years,evident difference existed in different dimensions and total scores.Conclusions The overall core competency is at the upper middle level for registered nurses from five tertiary level first-class hospitals in Liaoning Province.They are competent enough to provide health care.With the increasing length of working time,nurses' core competency level will strengthen gradually.

Objective To study the expression and pathologic significance of CD147,cyclophilin A (CyPA)and cyclophilin B(CyPB)in psoriatic lesions.Methods Immunohistochemical method was ap- plied to detect the expression of CD147,CyPA and CyPB in skin specimens of 15 patients with psoriasis pustulosa(PP),20 patients with progressive psoriasis vulgaris(PPV),and 20 patients with inactive psori- asis vulgaris(IPV).Immunoreactivity intensity distribution index(IRIDI)was calculated to assess the expres- sion intensity of CD147,CyPA and CyPB.Results CD147,CyPA and CyPB were detected in all speci- mens.The IRIDI scores of CD147 and CyPA were significantly higher in keratinocytes of psoriatic lesions than in those of the control specimens(all P0.05).The IRIDI score of CyPB in T lymphocytes of PP lesions was significantly elevated than that in PPV lesions,which was in turn higher than that in IPV lesions(all P0.05).Conclusion CD147,CyPA and CyPB may play a role in the occurrence and development of psoriasis.

Objective To explore the bioactive constituents of Gentiana rhodantha for its serum pharmacochemistry research.Methods The blood migrating constituents of Gentiana rhodantha were determined by comparing the HPLC fingerprints of the aqueous extracts,drug contained serum and blank serum.Results Twenty compounds were detected in drug contained serum,four among which were original constituents of Gentiana rhodantha,the rest might be metabolites of the original ingredients.Conclusion These twenty constituents absorbed in blood could be the bioactive components of Gentiana rhodantha.Further studies will be useful to clarify the bioactive constituents and action mechanisms of Gentiana rhodantha.

Objective To study the impact of the off-pump coronary artery bypass compared to the on-pump coronary artery bypass technique on the rate of acute kidney injury.Methods A retrospective analysis of 824 patients accepted coronary artery bypass surgery in FuWai Hospital Surgical ICU from March 2011 to January 2013.Patients were divided into two groups according to the surgical approach,597 patients in on-pump group and 227 patients in off-pump group.Then compared the difference of acute kidney injury incidence in the two groups.Results 92 patients in the on-pump group occurred AKI,the incidence of AKI was 15.4％.32 patients in the off-pump group occurred AKI,the incidence of AKI was 14.1％.Two groups of patients had no statistical difference in the incidence of AKI,x2 =0.222,P =0.638.Based on the preoperative baseline creatinine clearance levels.We defined normal creatinine clearance (SCR ≥ 60 ml/min),mild renal insufficiency (45 ml/min ＜ SCR ＜60 ml/min),moderate renal dysfunction group(31 ml/min ＜ SCR ＜45 ml/min).Decline with the preoperative creatinine clearance rate,the AKI incidence was elevated significantly,P ＜0.05.Patients with moderate renal insufficiency,offpump patients had lower incidence of AKI than those in on-pump group,P ＜ 0.05.The incidence of renal replacement in the two group patients had no statistical differences.Conclusion The incidence of AKI after coronary artery bypass surgery had no statistical differences with or without pump.In the patients with preoperative moderate renal insufficiency,off-pump can reduce the incidence of AKI,but could not change the kidney the incidence of renal replacement treatment.

Objective To explore the correlation between lower urinary tract symptoms (LUTS) with prostate volume and peak flow rate in aging staff men with benign prostatic hyperplasia (BPH). Methods A total of 180 elderly patients were randomly enrolled. They were diagnosed with BPH by rectal touch and transected ultrasound from April 2008 to December 2008. The international prostate symptom score (IPSS), prostate volume (PV) as well as peak flow rate (QMAX)were analyzed respectively. Results IPSS were ( 9. 1 ± 0. 7 ) scores, ( 12. 1 ± 0. 7 ) scores and (14.0±1.3) scores in 60-69 years old group, 70-79 years old group and more than 80 years old group. PV were (40. 6±1.9) ml, (42. 4±1.9) ml and (48. 7±2.8) ml in corresponding groups, and PV was elevated along with aging (F= 5. 705, 2. 983, P＜0. 05). QMAX were ( 14.7 ± 0. 6) ml/s,(14.0±0. 5) ml/s and (12.6±0.9) ml/s, and QMAX was decreased along with aging (F=2. 131, P＞0. 05). Along with aggravation of LUTS, PV (ml) increased (39. 2±18. 1 vs. 45.7±16.9 vs. 47. 9± 16. 5) and QMAX (ml/s) decreased ( 15.0 ± 4.8 vs. 13. 5 ± 5.06 vs. 11.5 ± 4. 7, F= 3. 427, 4. 742, P ＜0.05). Conclusions The LUTS of patients with BPH is aggravated with aging, at the same time, the degree of LUTS increases with PV and decreases with QMAX. If get active treatment of drugs if available, they may improve their quality of life.

Objective To detect the expression of SALL4 in patients with acute myeloid leukemia (AML) and analyze its potential clinical significance. Methods Reverse transcription polymerase chain reaction and Real-time fluorescence quantitative reverse transcription polymerase chain reaction (FQ-RT-PCR) was used to examine SALLA expression in peripheral blood mononuclear cells (PBMCs) of 68 cases of AML including 36 cases in acute phase and 32 cases in remission phase, 30 healthy controls, Kasumi-1 cells and THP-1 cells. Then, flow cytometry, bone marrow smear and automated hematology analyzer were used to analyze the relationship between the SALL4 expression and blast cell counts in the bone marrow, peripheral white blood cell (WBC) counts, peripheral large unstained cell (LUC), CD34 in blast cells. Further, the change of SALL4 level during pre-chemotherapy, chemotherapy (2nd w to 3rd w) and remission were investigated in 5 AML cases. Results The level of SALL4 expression in patients with AML in acute phase [69.01 (17.20-120.28)] was 26-fold and 61-fold high compared with that in remission phase [2.64(1.35-5.41)] and in healthy control [1.14(0.50-1.62)] (Z=-6.48,-6.83,P<0.01). The level of SALL4 expression in remission phase was 2.3-fold high compared with that in healthy control (Z=-3.61 ,P<0.01). The expression level of SALL4 was decreased along with efficient chemotherapy in 5 AML cases in which SALL4 expression level was 79.74 (33.76-89.09), 7.19 (5.97-20.21) and 3.40 (1.44-15.53) during pre-chemotherapy, chemotherapy (2nd w to 3rd w) and remission, respectively. In groups of abnormal increased counts of blast cell, peripheral LUC% and CD34%, expression of SALL4 [33.82 (16.00-144.01), 30.70(23.75-72.50) and 56.25(23.79-153.81), respectively] were higher than that in groups of normal counts [2.74 (1.59-5.13), 5.71 (2.52-22.40) and 20.82 (14.03-55.12), respectively ] (Z=-4.64,-2.18,-3.66,P<0.01 or P<0.05). The expression of SALL4 in the group of increased WBC counts [89.26(23.75-154.34)] was higher than that in the group of normal WBC counts [3.86(2.03-6.01)] and the group of decreased WBC counts [6.66(2.51-17.06)] (Z=-4.91,-4.21,P<0.01). The level of SALL4 expression was positively correlated with blast cell counts in bone marrow and peripheral WBC counts (r=0.45,0.40,P<0.01). Conclusions FQ-RT-PCR method can be used successfully to detect the expression of SALL4,and the expression of SALLA may be useful to predict disease progression of AML.
