Objective To discuss the effect of targeted information support on the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention and its instructive significance to nursing work.Methods We randomized 118 patients treated with percutaneous coronary intervention whose sense of uncertainty and anxiety were relative intensive into the test group and the control group with 59 cases in each group.We gave routine health instructions to the control group while targeted information support besides routine health instructions to the test group.We investigated the patients in two groups by Chinese version of uncertainty scale and State Anxiety Inventory at 4 time points,that is ,the first day in hospital,night before the operation,24 hours after the operation and 1 day before leaving hospital.Results The anxiety level and sense of uncertainty about illness decreased at the night before operation,24 hours after operation and 1 day after operation compared with the control group.The sense of uncertainty and anxiety level has statistical difference between whatever two adjacent time points except for anxiety level between the time points between the first day in hospital and before operation.Drop of sense of uncertainty at 24 hours after operation was significantly different between the two groups(P<0.01).Conclusion Supplying targeted information support could decrease the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention.

Objective To summarize the treatment experience of acute cerebral infarction (ACI)combined with deep venous thrombosis (DVT) of lower extremities in the elderly. Methods Thirty cases of elder patients with ACI combined with DVT (ACI group) were enrolled in this study, and 31 cases of elder patients with DVT were served as control group. All the patients were immobilized for 3 days and treated with low molecular heparin calcium (100 IU/kg,Q12 hX14 d). On the tenth day,warfarin was used and INR was controlled in 2.0～2.5. Low molecular dextran was infused intravenously per day for 14 days (500mg/d). Results Edema in the lower limbs of patients were apparently reduced. 4 eases had cerebral hemorrhage in ACI group, and none in the control group.Hemorrhage occured from 3 to 7 days during the treatment with low molecular heparin calcium. One of the patient died of massive intraeranial hemorrhage with lung infection. Conclnsions It should be more careful to use the low molecular heparin to treat the elder patients older than 80 years old with ACI combined with DVT.

Objective To analyze the language function impairment differences between the two steps from the form to sound processing and from the sound to meaning processing for pseudo-words reading in Alzheimer' s disease (AD).Methods The pseudo-words reading test consists two parts:pseudo-true words and pseudopseudo words.Each part had 10 words.All of the 20 words were presented randomly.Correct reading presents the processing of from form to sound,and correct judging presents the processing of from sound to meaning.Each correct respond get 1 score,otherwise get 0.Each part had a total score of 20.Results The pseudo-words reading test was performed to 41 mild AD participants with Mini-mental State Examination (MMSE) average scores of (21.06 ±2.86),and 135 normal controls with MMSE average scores of (28.08± 1.52).The two groups were matched in age,gender and education.For all of the mild AD group and normal control group,there was no significant difference between reading score and judging score in either pseudo-true words or pseudo-pseudo words (P＞0.05).Comparing with mild AD group and normal control group,there was no significant difference in reading score in either pseudo-true words or pseudo-pseudo words (P＞0.05).For judging score,there was significant difference in pseudotrue words (P＜0.01) but not in pseudo-pseudo words (P＞0.05).Conclusion Understanding real syllable is impaired in patients with mild AD.

Objective To study the impact of local fractionated irradiation on lung metastasis in H22-bearing mice, and to explore its mechanism involved. Methods Subcutaneous transplantation tumor model bearing with H22 was established. Mice were divided into three groups as healthy control, tumor control and irradiation groups. The size of subcutaneous tumors was measured and lung metastasis was observed. The expressions of PCNA, VEGF and MVD were detected immunohistochemically. The plasma levels of CD4 and CD8 were determined by using flow cytometry. Results The tumor size in irradiated group was smaller than that in tumor control group. The tumor inhibition rate in irradiated group was 30%.Lung metastasis in irradiated group was more severe than that in tumor control group (x2 = 8.31,4.48,9. 60, P＜ 0.05 ). The expressions of PCNA, VEGF and MVD in two groups were statistically different( t =23.78,-2.47, -6.43, P ＜ 0. 05). The levels of CD4 and CD8 in irradiated group were statistically different compared to healthy control group ( t = 4. 72 and 3.31, P＜ 0.05 ). Conclusions For the H22 model, radiation might inhibit the local transplantation tumor, but increase the risk of lung metastasis.

Objective To explore the effects of hyperbaric oxygen(HBO) on brain derived neurotrophic factor(BDNF) and the changes of neuron structure after cerebral ischemia-reperfusion(CIR) in mice. Methods Twenty-seven mice were randomly and evenly divided into three groups : a HBO group, a control group and a sham-operation group (SO group). CIR models were established by clamping both carotid arteries in mice for 30 min,and then, untying clamps. 0.20 MPa HBO was applied once a day for 10 days after establishment of models in HBO group,but not in the control and SO groups. Following sacrifice after treatment and acquirement of cortex and hippocamal tissues, HE stain and immunohistochemistry technique were used to observe the changes of neuron structure and expression of BDNF. Results The neural degeneration and necrosis in cortex and hippocampus (issues) were observed under light microscope after CIR, and the amount of abnormal cells in the control group was more than that in HBO group (P
