Objective: To investigate the current situation and influence factors of perceived professional benefits among nurses working in day-care unit. Methods: Convenience sampling method was adopted, totally 245 nurses working in day-care unit were investigated by nurses' perceived professional benefit questionnaire, psychological capital questionnaire, psychological sub-health questionnaire and a self-designed demographic questionnaire. The data were collected and analyzed statistically. Results: The scores of perceived professional benefit among nurses working in day-care unit were 117.96±14.06. Multiple regression analysis shows that working years, scores of psychological capital questionnaire and psychological sub-health questionnaire were positive factors to perceived professional benefit; while the education level was negative predictors to perceived professional benefit. The regression equation was: the scores of perceived professional benefit among nurses = 70.582-4.882 x the education level + 2.520 x working years+ 0.329 x scores of psychological capital questionnaire + 0.250 x psychological sub-health questionnaire. Conclusions It showed higher level of perceived professional benefit as tested in previous study. Managers can pay more attention to nurses with less working years and higher degree of education, and improve the level of psychological capital and mental health, so as to improve the level of perceived professional benefit.

OBJECTIVETo examine the associations of apparent diffusion coefficient (ADC) value from MR diffusion-weighted imaging (DWI) with Ki-67 expression and differentiation grade in gastric cancer.

METHODSImages and pathologic data of 68 gastric cancer patients between September 2013 and February 2015 in Affiliated Changshu Hospital of Soochow University were analyzed retrospectively. The expression of Ki-67 antigen in cancer tissue sample was determined by immunohistochemistry. Ki-67 labeling index(LI) was calculated to divide the cases into low Ki-67 group(Ki-67 LI <50%) and high Ki-67 group (Ki-67 LI ≥ 50%). Associations of ADC value with differentiation grade and Ki-67 LI were examined.

RESULTSMean ADC value of low Ki-67 LI group was significantly higher than that of high Ki-67 LI group [(0.977 ± 0.100) × 10(-3) mm(2)/s vs. (0.859 ± 0.064) × 10(-3) mm(2)/s, P=0.000]. The ADC value was negatively correlated with Ki-67 LI (r=-0.685, P=0.000). Mean ADC value of well differentiated adenocarcinoma, moderately differentiated adenocarcinoma, poorly differentiated adenocarcinoma, and signet-ring cell carcinoma was (1.124 ± 0.080) × 10(-3) mm(2)/s, (0.950 ± 0.064) × 10(-3) mm(2)/s, (0.899 ± 0.091) × 10(-3) mm(2)/s, and (0.894 ± 0.081) × 10(-3) mm(2)/s respectively. Difference of ADC value among differentiation grades was significantly different (F=11.405, P=0.000). Difference of ADC value between well differentiated adenocarcinoma and non-well differentiated adenocarcinoma was significantly different(P=0.000).

CONCLUSIONADC value is associated with differentiation grade and Ki-67 LI of gastric cancer, which may be used as a noninvasive predictor for evaluating the proliferation and differentiation grade of gastric cancer.

OBJECTIVETo investigate the value of diffusion-weighted imaging (DWI) in the diagnosis of T staging for rectal cancer.

METHODSClinicopathologic data and MR images of 46 patients with rectal cancer in our hospital from July 2013 to September 2014 were retrospectively analyzed. The diagnostic sensitivity, specificity and accuracy of T2WI were compared with those of T2WI plus DWI in T staging for rectal cancer. The relationship of mean apparent diffusion coefficient (ADC) value with different T stages of rectal cancer was analyzed.

RESULTSThere were no significant differences in the diagnostic sensitivity, specificity and accuracy between T2WI and T2WI plus DWI (all P>0.05). The mean ADC value of DWI performed in pathologic T2, T3a, T3b, T3c and T4 stage was (1.110 ± 0.117) × 10⁻³ mm²/s, (1.035 ± 0.121) × 10⁻³ mm²/s, (0.948 ± 0.109) × 10⁻³ mm²/s, (0.932 ± 0.122) × 10⁻³ mm²/s and (0.843 ± 0.050) × 10⁻³ mm²/s, respectively (F=6.972, P=0.000).

CONCLUSIONDWI can serve as a complement for T2WI in the diagnosis of T stage patients with rectal cancer, and its ADC value presents a downward trend with the advance of T stage.

UNLABELLEDThis investigation was made to explore the chaotic characteristics of cardiac system and differences of autonomic nervous system development of normal pregnant rats and fetuses. The electrocardiograms, chaotic graphics and digital characteristics of heart period signal (HPS) of normal pregnant rats and fetuses by day 21st were evaluated with a computerized HPS extracting and analyzing system.

RESULTS(1) The mean values of frequency and voltage of fetal rats electrocardiograms were lower than those of pregnant rats significantly (P < 0.01). (2) Being similar to those in human, the chaotic graphics showed three-amplitudes spectral features in both normal pregnant rats and fetuses. However, the second amplitude and third amplitude were lower in fetal rats than in pregnant rats. (3) The Heart Relative Dispersion, Lyapunov Exponent and Fractional Dimension were significantly lower in fetal rats than in pregnant rats (P < 0.01). These findings demonstrated that the autonomic nervous system development of fetal rat was still immature and it exhibited lower complexity of HPS and chaotic degree than that of pregnant rat did.

UNLABELLEDTo investigate the relationship between imbalance of cardiac autonomic nervous system and sudden death in fetuses of rats with intrahepatic cholestasis of pregnancy (ICP), the animal model of ICP was induced by hypodermic injection of 17-alpha-ethinylestradiol and progesterone. The electrocardiograms and frequency domain analysis of heart rate variability (HRV) including low frequency (LF), high frequency (HF) and the ratio between low and high frequencies (LF/HF) of fetal rats by the 21st day of gestation were evaluated with Chart 5 software of Powerlab biologic signal extracting and analyzing system.

RESULTS(1) The serum total bile acids (TBA) levels of pregnant rats were (78.5 +/- 4.5) micromol/L in Group ICP and (24.6 +/- 3.6) micromol/L in Group control; significant difference was noted between the two groups (P < 0.01). (2) In Group ICP, fetal rats arrhythmias appeared after (29.3 +/- 6.4) minutes' observation, and fetal rats died suddenly after (23.5 +/- 4.6) minutes' arrhythmias; However, the fetal rats in Group control all showed normal electrocardiograms over 90 minutes' continuous observation. (3) The values of LF and LF/HF of fetal rats in Group ICP within 20 minutes before fetal rats arrhythmias were significantly higher than those in Group control (LF 48.45 +/- 4.11 nu vs. 33.87 +/- 4.31 nu, and LF/HF 0.99 +/- 0.14 vs. 0.61 +/- 0.10, respectively, P < 0.01). (4) Dynamic power spectral analysis of HRV indicated that the values of LF and LF/HF of fetal rats in Group ICP increased progressively within 15 minutes before the sudden death of fetal rats. These demonstrated that autonomic imbalance in association with increased sympathetic activity has been strongly implicated in the pathophysiology of fetal arrhythmogenesis and sudden death in ICP. HRV analysis could be a useful tool for fetal surveillance, especially for ICP.

OBJECTIVETo investigate retrospectively the efficacy of cyclosporine A (CsA) in the treatment of membranous lupus nephropathy (MLN).

METHODSTwenty-four patients with systemic lupus erythematosus (SLE) and biopsy-proven MLN were treated with CsA in combination with prednisone. CsA was given at a starting dosage of 5 mg x kg(-1) x d(-1) for 3 months, with a 1 mg x kg(-1) x d(-1) reduction every month and then maintained at a dosage of 2 mg x kg(-1) x d(-1). The dosage of oral prednisone differed from person to person according to levels of extra-renal activity. Clinical efficacy and adverse reactions were retrospectively analyzed. Complete remission was defined as having a urinary proteinuria level (Upr) of < 0.4 g/d, and normal serum albumin and serum creatinine (SCr) levels, without SLE activity. Partial remission was defined as having a UPr decrement > 50% of baseline value and a serum albumin value of 30 - 35 g/L, without SLE activity. No response was defined as having a Upr decrement < 50% of baseline value and > 2.0 g/d, or as a deterioration of renal function, or as having active SLE.

RESULTSOne patient could no longer undergo follow-up, and the other 23 patients were treated with CsA and followed up for 6 - 36 months (mean 16.8 +/- 8.4 months). The mean starting dosage of CsA was 4.7 +/- 0.5) mg x kg(-1) x d(-1) and the trough level of the whole blood CsA was 248 +/- 110) micro g/L. Twelve patients (52.2%) achieved complete remission, 10 patients (43.3%) achieved partial remission after CsA treatment, and one patient showed no response. At different CsA treatment timepoint, the complete remission rates were 17.4% (3rd month), 21.7% (6th month), 40% (12th month), 88.9% (18th month) and 100% (24th month) respectively. SCr elevation, when within a normal limit was not observed in most patients during early CsA administration, and at the end of the follow-up all the patients had a normal SCr. Relapse occurred in 33.3% of the patients after withdrawing CsA for 4 - 24 months. No chronic CsA renal toxicity was observed in 4 patients who had a repeat renal biopsy after CsA treatment for 6 - 24 months.

CONCLUSIONSCsA could be regarded as an effective therapy for patients with membranous lupus nephropathy, but its adverse effects, especially its nephrotoxicity, should be carefully monitored during CsA treatment.
