Objective To study the clinical application of 3-dimensional arterial spin labeling technology (3D-ASL) in brain tumors.Methods Twenty patients with the pathological diagnosis of brain tumors were selected in this study,with low grade glioma in 4 cases,the high grade glioma in 2 cases,lymphoma in 1 case,metastatic tumor in 7 cases,meningioma in 6 cases.All patients were appLIed preoperative 3D-ASL and dynamic contrast-enhanced perfusion magnetic sensitive (DSC) MR imaging line two methods,to analyze the value of 3D-ASL in brain tumors.Results 3D-ASL examination lesions in patients with brain tumors might be displayed in high or low perfusion; 3D-ASL and DSC were obtained from tumor tissue blood supply,the local relative cerebral blood flow (rCBF),there was no significant difference (P ＞ 0.05).The high grade glioma in 3D-ASL image showed a high perfusion,rCBF was 3.0 ± 1.3; Low grade gliomas showed low perfusion,rCBF was 0.6 ± 0.2,the rCBF between the high-and low-grade gliomas was significantly different (P ＜ 0.01).Metastatic tumor 3D-ASL showed ring high perfusion,central necrosis and edema area of low perfusion.Lymphoma 3D-ASL showed slightly higher perfusion.Meningioma showed high perfusion,and highest rCBF,3.5 ± 1.9.Conclusions 3D-ASL in the diagnosis of brain tumors,has high repeatability,non-invasive,without contrast agent.3D-ASL can be further developed into the brain blood flow dynamics of conventional evaluation methods,and can be used for brain tumors level assessment,has broad application prospects.

The acute respiratory distress syndrome,a common severe case,can cause life-threaten multiple organ failure.Statins has been clinically applied in prevention of cardiovascular diseases and cerebrovascular disease.Previous studies indicate that statins can modulate inflammatory responses.In this paper,we discussed the mechanisms of statins,mechanisms and application of statins in acute lung injury and acute respiratory distress syndrome,and the effectiveness and safety of statins.

Objective To explore the impact of health education on negative mood,social support and life quality of patients with breast cancer.Methods 90 patients with breast cancer receiving chemotherapy were divided into the observation group and the control group randomly,and each group with 45.The regular health education was given to the control group,and personalized health education was provided to the observation group and their related family member,the measures included mental communication,psychological counseling and life guidance.SAS,SDS,SSRS and QOL were carried out at two time points:the time when admission to hospital and 4 weeks after admission.Results Before health education,there were no statistical significance between the observation group and the control group on anxiety,depression,social support and life quality.After health education,the observation group was better than the control group in scores of anxiety,depression,social support and life quality.Conclusions The health education given simultaneously to the patients and their family members can improve their negative mood,increase their social support,and improve their life quality.

Objective:To establish the parallel bi-vein graft with valves animal model and to seek a new surgical method for patients with deep valvular incompetence.Methods:The parallel bi-vein with valves autogenic graft animal model was established in 12 rabbits by microsurgery and the hemorheology and hemodynamics were examined by real time color-duplex scanning and phlebography.Results:Among all of the 12 rabbits, autogenic graft of the parallel bi-vein with valves animal model was successfully established and was under observation for 4 weeks postoperatively.Only in 1 rabbit it was obstructed after 4 weeks.The rest remained unobstructed and were kept in favorable configuration and steady blood stream with laminar flow.Conclusion:The autogenic graft parallel bi-vein containing valves by microsurgery technique in rabbits is feasible.The opretion may be a feasible and promising method for clinical patients with chronic venous insufficiency in lower limb.

Objective To discuss the difference of preoperative examination and matters needing attention between osteoarthritis(OA)and rheumatoid arthritis(RA)patients who received total knee replacement(TKR).Methods Preoperative examination results were analyzed retrospectively between OA patients(362 cases)and RA patients(91 cases)who received TKR.Results The age of OA patients was significantly higher than RA patients[(66.55±7.78)years vs.(58.93±13.46)years,P＜0.05].There was significant difference in rate of diabetes between OA and RA patients[26.52％(96/362)vs.37.36％(34/91),P＜0.05].There was no significant difference in the rate of lumbar vertebrae disease between OA and RA patients[33.43％(121/362)vs.23.08％(21/91),P＞0.05].The body mass index,haematocrit and hemoglobin in OA patients were significantly higher than those in RA patients[(27.71±3.98)kg/m2 vs.(24.37±4.30)kg/m2,0.38±0.05 vs.0.33±0.06,(130.17±17.59)g/L vs.(111.45±18.56)g/L,P＜0.01].The erythrocyte sedimentation rate,C-reactive protein and D-dimer in OA patients were significantly lower than those in RA patients[(27.77±27.66)mm/1 h vs.(59.76±32.00)mm/1 h,(17.23±27.66)mg/L vs.(30.00±32.27)mg/L,(268.54±299.83)μ g/L vs.(990.09±550.91)μg/L,P＜0.01 or＜0.05].The rate of using glucocorticoid in RA patients was significantly higher than OA patients[8.8％(8/91)vs.0,P＜0.01].There was no significant difference in the rate of urinary system infection(P＞0.05).Conclusions The preoperative examination is found significantly different between OA and RA patients who received TKR.According to different focuses on,dealing with various kinds of complications and correct guidance on preoperative treatment,can ensure the safety of operation.

OBJECTIVE To discuss rational layout of Sterilizing and Supply Room in the Department of Stomatology and its scientific utilization of sterilizing equipment which ensure safe medical treatment of patients. METHODS Funds should be invested to the Stomatology Department according to plan and environment and equipment should be transformed. RESULTS Transformed conditions of Sterilizing and Supply Room had conformed to Operation Rules of Sterilization of Dental Medical Instruments in Medical Institutions promulgated by the Ministry of Health.One patient could certainly use his own medical goods with absolute sterilization.This not only reduced opportunities of cross infection,but also protected and made things convenient for medical personnel. CONCLUSIONS The fundamental guarantee of safe medical treatment of patients is rational layout of Sterilizing and Supply Room in the Stomatology Department and rational allocation and scientific utilization of sterilizing equipment.

Objective To explore the effect of comprehensive experiments on clinical practice of internal medicine nursing in the patients with advanced simulation human Simman3G.Methods Two grades of nursing students were selected by random cluster sampling and divided into the experimental group and the control group.The control group used the traditional clinical probation method to carry out clinical probation teaching in Department of internal medicine,the experimental group used the advanced simulation human Simman3G to conduct a comprehensive simulation of teaching before clinical probation.After the completion of the internship the self compiled questionnaire was given to two groups of students to investigate their opinion on the clinical probation.Then we compared,the semester examination results between two groups.Results In the experimental group,the grade of internal medicine nursing was higher than the control group at the end of the semester,P ＜ 0.05.The results of questionnaire survey showed that there was no significant difference between the two groups in the promotion of theoretical knowledge and the two dimensions of the survey of nursing work environment.In the training of clinical thinking,improve nursing skill,communication skill,and the learning interest.At the great harvest of 5 dimensions of probation,the experimental group of students' recognition degree was significantly higher than the control group,P ＜ 0.01.Conclusion Before clinical probation of internal medicine nursing,the application of high-end analog teaching can significantly improve the effectiveness of clinical probation.
