Objective To investigate the differences in the attitudes toward physician-nurse collaboration among undergraduate nurses and physicians,and provide evidence for creating good physiciannurse atmosphere of cooperation.Methods The Jefferson Scale of Attitudes toward Physician-Nurse Collaboration (JSAPNC) was administered to 96 undergraduate nurses and 52 physicians in admitting department.Results The participants' score of JSAPNC were relatively high,especially on the items Caring as opposed to curing and Nurse autonomy.The score of undergraduate nurses was lower than physicians on the item there are a lot of overlap responsibilities between nurses and physicians ;the score of undergraduate nurses was higher than physicians on the item physician authority.Conclusions Undergraduate nurses and physicians have a positive attitude toward physician-nurse collaboration.Nurses believe that some of their duties are common during their work,but the communication was not ideal.The overall health care rounds should include physicians and nurses,which can increase the communication,strengthen the spirit of collaboration and create good physician-nurse atmosphere.

Objective To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive ability in patients suffering from mild cognitive impairment (MCI) after ischemic stroke.Methods Forty five ischemic stroke survivors with MCI but not meeting the criterion for diagnosis as dementia were recruited, and were randomly assigned into an rTMS group (32 patients) and a control group (30 patients) according to a random number table.Both groups received the routine drug therapy of medicine and cognitive function training, and the rTMS group was additionally given rTMS over the left dorsolateral prefrontal cortex at 5 Hz and 80％ motor threshold.The treatments lasted for 4 weeks.The Montreal Cognitive Assessment (MoCA) and auditory event related potential (ERP) were tested for both group before and after the treatment.Results After the treatment, two groups showed significant improvements in the average score of MoCA compared to that before the treatment, and that of the rTMS group was significantly higher than that of the control group.For both groups, the P300 latency shortened and the amplitude increased after the treatment.Moreover, the latency and amplitude of the rTMS group increased to 355.67 ± 16.43 ms and 8.69 ± 1.65 μV, respectively, after the treatment, significantly shortened and lengthened than that of the control group [(372.76 ± 23.35 ms and 7.03 ± 3.04 μV), respectively].Conclusions rTMS can significantly improve the cognitive ability of ischemic stroke survivors in a relatively safe way.

Objective To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive ability of patients after ischemic stroke. Methods 45 patients with mild cognitive impairment (MCI) after ischemic stroke were randomly assigned into control group (n=22) and observation group (n=23). Both groups received routine drugs and cognitive training. The observation group received rTMS over the left dorsolateral prefrontal cortex (DLPFC) (5 Hz, 80% motor threshold) in addition for 4 weeks. Results The score of Montreal Cognitive Assessment (MoCA), P300 latencies and amplitudes improved after treatment in both groups (P<0.001), and were better in the observation group than in the control group (P<0.05). The MoCA score was negatively related with P300 latency (r=-0.851, P<0.05). There was no severe adverse effect during the treatment. Conclusion rTMS could improve the cognitive ability of patients with MCI after stroke, with little side effect.

ObjectiveTo assess the effect of comprehensive rehabilitation on facial paralysis.Methods80 patients with facial paralysis were divided into observation group receiving comprehensive rehabilitation(medicine, physical therapy, functional exercise and psychological treatment), and control group with medicine and physical therapy.ResultsThere was a significant difference in the scores for Portmann's Simple Scale between before and after treatment in two groups (P<0.01). There was a significant difference in the clinical effect between observation group and control group (P<0.05).ConclusionComprehensive rehabilitation has a better effect on facial paralysis.

In this paper the application of DNA fingerprints to evaluate the efficiency of DNA extraction was studied DNA mixtures of landfill leachate and active sludg e were extracted using three different methods and the DNA extraction was evalua ted by ARDRA and RISA fingerprints The results showed that RISA is a effecti ve way to evaluate DNA extraction

BACKGROUND:Titanium aloy and stainless steel are two common internal fixation materials, but there are some difference in their therapeutic effects and biocompatibility. OBJECTIVE:To explore the therapeutic effects and biocompatibility of titanium aloy and stainless steel internal fixation materials for the treatment of spinal tuberculosis. METHODS:Seventy-one spinal tuberculosis patients, 35 males and 36 females, aged 17-81 were enroled. Among them, 35 patients received titanium aloy internal fixation, and the 36 patients underwent stainless steel internal fixation. At the end of 12-month folow-up, Cobb angle changes, therapeutic effect and Frankel grade were analyzed in the two groups. RESULTS AND CONCLUSION:Before treatment, there was no difference in the spinal kyphosis angle and Frankel grade between the two groups. At the last folow-up, the Frankel grade and Cobb angle were both improved in the two groups (P < 0.05), but there was stil no difference between the two groups. The cure rate was 97% (n=34) in the titanium aloy group and 92% in the stainless steel group (n=33), and no significant difference was found between the two groups. These two kinds of internal fixation materials exhibited good biocompatibility, and no infection and other adverse reactions occurred. These findings indicate that both titanium aloy and stainless steel as internal fixation materials have good biocompatibility and therapeutic effects.

Objective:To investigate the effects of Daidzein on behavior of chronic stress depression rats and the expression of hippocampal brain-derived neurotrophic factor ( BDNF ) , neuropeptide Y ( NPY ) and non-specific immune regulation.Methods: 40 healthy adult male SD rats with body weight(210±19)g,clean grade,were chosen and fed with 1%sucrose solution for 4 d to change drinking habits.On the fifth day rats were subjected to water deprivation for 24 h without fasting.On the sixth day rats were fed with 1%surcrose solution.4 h later, preference of 1% surcrose solution was examined.According to the 1% sucrose solution preference and weight rats were randomly divided into 4 groups,normal control group(CG),model control group,(MG),fluoxetine group(FG,10.0 mg/kg),daidzein group(DG,80.0 mg/kg).At the same time of establishing model,rats were administered orally once a day for 32 d.The depression model was established by chronic unpredictable mild stress model and separation.The behavioral changes of the rats were observed, and expression of BNDF in hippocampus and NPY was measured by Western blot technology and immunohistochemistry.It was observed the proliferation function of lymphocytes,spleen index,the number of peripheral blood leukocytes and antibody-secreting cell function.Results: Compared with the normal control group(CG),the weight of rats with chronic stress protocol was lower, 1%sucrose consumption decreased,scores of rats in the open field test dropped significantly,the immobility time in the forced swimming test prolonged,the level of expression of BNDF and NPY decreased,all the differences above were statistically sig-nificant(P<0.01).Compared with model group,weight of rats in fluoxetine treatment group(FG) and daidzein treatment group(DG)in-creased,sugar consumption,scores in the open field test and the levels of expression of BNDF and NPY significantly increased,the differences were statistically significant( P<0.05 or P<0.01 ).The number of peripheral blood leukocytes and antibody-secreting cell function and proliferation of lymphocytes force in daidzein treatment group was significantly higher than the model group,daidzein dose spleen index was significantly higher than the model group(P<0.01).Conclusion: The daidzein can antagonize depressive symptoms in chronic stress mice,daidzein may increased content of BDNF in hippocampus and NPY protein, and enhanced the role of humoral immune response and lymphocyte proliferation in rats with chronic stress model.The mechanisms of antidepressant effects of daidzein might be related to the increase of content of BDNF in hippocampus and NPY protein and non -specific immune regulation.

Established rat models with subclinical hypothyroidism (SCH) were divided into three groups:subclinical hypothyroid(SCH),SCH treated with levothyroxine (L-T4),and control group.The L-T4 group displayed lowered total cholesterol and endothelin levels compared with the SCH group[(1.29 ±0.05 vs 2.38 ±0.55) mmol/L,(98.54 ± 32.43 vs 160.62 ±37.25) nmol/L,both P＜0.05].Nitric oxide levels,left ventricular systolic pressure,and blood flow in abdominal aorta were significantly higher in the L-T4 group than those in the SCH group.The results of this study indicate that L-T4 treatment may improve endothclial dysfunction and hemodynamic changes in rats with SCH.
