Chinese Journal of Practical Nursing 2009;25(9):15-18
Objective To explore the impact of nursing intervention on negative moods, compliance behavior and life quality of patients with chronic heart failure (CHF). Methods We randomized 100 patients with CHF into the observation group and the control group. The control group only accepted basic nursing, life nursing and treatment; besides these, the observation group were given other interventions, including health education, comfortable environment, physical activity, compliance behavior, diet and mental guidance 3 days after the patients were admitted into hospital. The two groups were tested for anxiety, depression, compliance behavior as well as life quality with Minnesota Living with Heart failure questionnaire both 3 days after the patients were admitted into hospital and when they were discharged. χ2 test and t test were used to analyze the data. Results Before intervention, there were no statistical difference in their anxiety, depression, compliance behavior, and life quality between the observation group and the control group. After intervention, the observation group was superior than the control group in anxiety and depression score, compliance behaviors including on-time medicine administration, regular recheck, rational diet, smoke abatement and alcohal restriction, physical activity, life quality score including physical limitation, emotion, symptom and social constrain. Conclusions Nursing intervention could help improve anxiety and depression of the patients with CHF, promote their compliance behaviors and improve their life quality.

OBJECTIVE:To compare the pharmacodynamics of active parts in crude Atractylodes lancea and A. lancea fired with bran. METHODS:170 rats were randomly divided into 17 groups,including blank control group,spleen and stomach damp obstruction model group,volatile oil of crude A. lancea and A. lancea fired with bran high-dose and low-dose(0.747,0.083 mg/ml by the concentration of crude medicinal materials,similarly hereinafter)groups,solvent control 2% polysorbate 80 group,dichlo-romethane extract of crude A. lancea and A. lancea fired with bran high-dose and low-dose groups,solvent control 1‰ polysorbate 80 group,n-butyl alcohol extract of crude A. lancea and A. lancea fired with bran high-dose and low-dose groups,solvent control stomach damp obstruction model distilled water control group. Except blank control group,other 16 groups were given Sennae foli-um decoction ig for 14 d to induce spleen and stomach damp obstruction model,and then received relevant medicine or solvent ig once a day for consecutive 7 d. Body weight of rats were determined before and after medication,and the serum levels of amylase, D-xylose,gastrin,vasoactive intestinal peptide and NO were determined after medication. RESULTS:Compared with spleen and stomach damp obstruction model group,the body weight and serum levels of gastrin,amylase and D-xylose increased significantly in rats of active part in A. lancea fired with bran groups(P<0.05),while vasoactive intestinal peptide and NO decreased signifi-cantly(P<0.05). Compared active part in crude A. lancea group,except the body weight,above indicators of active part in A. lan-cea fired with bran groups had greater change,with statistical significance (P<0.05). CONCLUSIONS:There are pharmacody-namic differences in the active parts between crude A. lancea and A. lancea fired with bran,the latter one is stronger.

Objective To evaluate the feasibility of multi-parameter MRI in diagnosing ovarian endometrial cysts. Methods Pelvic MRI of 68 patients with confirmed pathological diagnosis were retrospectively reviewed. The patients were divided into ovarian endometriosis (35 patients with 42 lesions, group A) and other cystic lesions (33 patients with 38 lesions , group B).The signal intensity value of T1WI, T2WI of cyst fluid and iliopsoas, ADC value, phase values and R2*values were obtained, cyst fluid/iliopsoas ratios (T1R and T2R) were calculated. The non-parametric Mann-Whitney U test was employed to compare parameter values between the two groups. The values of diagnostic performance were analyzed by using receiver operating characteristic curve (ROC). Use the Logistics regression parameters of diagnostic efficacy to select the highest Youden index for the best parameter association after combining the parameters step by step. Results The median of T1R, T2R, ADC, phase, T1R and R2*values for group A were 3.39, 5.28, 1.20×10-3 mm2/s,2.19×10-2, 15.08 Hz respectively, and that of group B were 0.91, 10.85, 2.64×10-3mm2/s,2.67×10-2, 3.01 Hz, respectively. There were statistically significant difference between the two groups (P<0.01).The AUC of T1R, T2R, ADC value, phase values and R*2 value were 0.930, 0.874, 0.891, 0.685 and 0.924 respectively, and there was no difference among them (P>0.05). When combining T1R, ADC value, R2*value together, the Youden index (0.849 7) was highest. Conclusion Combining T1R, ADC and R2* values can provide an effective way to discriminate endometrial ovarian cyst from other ovary cystic lesions.

Objective To evaluate the feasibility of renal artery angiography with interpolated finite impulse response (IRFR) sequence on 1.5T MR. Methods A total of 122 subjects underwent MR scan with IFIR sequence. On axial image of IFIR, bilateral signal-to-noise ratio (SNR) and breath artifact of renal artery were measured and 3D maximum intensity projection (MIP) images were reconstructed on workstation ADW 4.3, and each branch was scored according to its displaying quality. Influence of SNR, age and breath artifact on the displaying of renal artery were compared and analyzed. Results Renal segmental artery could be seen in 112 subjects (91.80%). Among them, segmental artery was showed clearly in 78 subjects (63.93%), post-segmental artery was showed in 54 subjects (44.26%) and branches of post-segmental artery was showed in 22 subjects (18.03%). There was statistical difference of renal artery scores mean rank between ≥60 years group and <60 years group (49.25 vs 67.48, P=0.006), as well as between the group without and with breath artifact (66.66 vs 43.35, P=0.002). No statistical difference of SNR was found among renal artery scores from 1-5 (P=0.177). Conclusion IFIR sequence is simple and safe for renal artery angiography on 1.5T MR, and different grades of renal artery branch can be showed clearly.

Cell morphometry method was applied in courting a nd analyzing 12 ultrastruc-ture morphological parameters of the rough endoplasmic reticulum and ribosome from 10 female patients of the simple breast carcinoma in the late stage by pathological diagnosis. The best equation was set up with stepwise regression analysis was as follows: y=0.22+0.503N6-013N7. Due to above equation, selecting the best parameters were the surface density of free ribosome N6 and specific surface of rough endoplasmic reticulum N7. They could be used to distinguish the normal cell-apparatus from carcinoma cell-apparatus. These results show that N6 and N7 in varying degrees could provide fixed quantity basis for the prognosis of breast carcinoma.
